Description:Rotational Print Mechanism for Spherical Objects
Field of the Invention
[0001] The present disclosure generally relates to printing systems. Further, the present disclosure particularly relates to a system for rotational printing of a spherical object.
Background
[0002] The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Rotational printing of objects, particularly non-planar and spherical items, is a field encompassing various techniques that seek to address the challenges inherent in applying precise printed materials onto curved surfaces. Spherical objects are frequently printed for applications including decorative items, sports equipment, and custom-designed consumer products. Such applications demand high levels of accuracy and uniformity across the object's surface. Conventional printing methods generally incorporate mechanical fixtures to stabilize the object during the printing process. Stabilization is particularly challenging in the case of spherical objects due to their curved surface, which presents difficulties in achieving a consistent print quality and aligning the object during rotation. Mechanical supports can induce unwanted friction and pressure points, further complicating the application of printing materials across the spherical surface.
[0004] A common technique for printing on spherical objects involves the use of fixtures or physical mounts to secure and rotate the object, enabling the printhead to deposit material while the object rotates. However, such techniques often lead to irregularities in the print quality, as frictional forces between the support mechanism and the object can cause misalignment, slippage, and other printing defects. Furthermore, the need for physical contact may introduce surface blemishes, compromising the aesthetic or functional integrity of the printed object. Although some methods attempt to reduce friction by minimizing points of contact, these approaches frequently fall short of ensuring the precision necessary for high-quality, uniform printing, particularly on spherical surfaces with intricate designs or patterns.
[0005] Additional approaches utilise suction-based systems to stabilize and rotate the spherical object during printing, aiming to eliminate or reduce frictional interactions. Such systems are designed to hold the object using vacuum force, which theoretically allows the object to rotate with reduced resistance. Nonetheless, in practice, suction-based systems present limitations, especially in sustaining a firm hold on spherical objects of varying dimensions or materials. Suction can also result in uneven tension across the object's surface, leading to minor deformation or shifting during rotation. These drawbacks become more pronounced in high-speed printing applications, where even slight positional shifts can lead to significant printing inaccuracies, detracting from the overall precision and reliability of the method.
[0006] Other systems incorporate automated robotic arms or multi-axis mechanisms that attempt to synchronize the rotation of the object with the printhead movement. While such systems theoretically enhance control and precision, they tend to be complex and cost-intensive due to the sophisticated coordination required. Robotic systems for rotational printing on spherical objects often demand substantial calibration and maintenance, as any misalignment or deviation from the programmed path can adversely impact print quality. Furthermore, such systems often lack flexibility, limiting their application to specific sizes and shapes of objects. Additional drawbacks include the increased operational costs associated with maintaining multi-axis robotic systems, which can be prohibitive for certain applications.
[0007] In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and techniques for achieving accurate and consistent rotational printing on spherical objects.

This control system enables stable levitation by continuously adjusting the magnetic force, ensuring that the spherical object remains in a fixed position during rotation. The electromagnetic feedback control system is essential for achieving consistent alignment and smooth rotation, thereby enhancing the accuracy and quality of the printing process. This system may include sensors, actuators, and control circuits to monitor and modify the magnetic field strength as required.
[00032] FIG. 1 illustrates a system (100) for rotational printing of a spherical object, in accordance with the embodiments of the present disclosure. The system (100) for rotational printing of a spherical object, such as a decorative sphere or customized sports ball, where high-precision printing is required across a curved surface. The system (100) comprises a magnetic support assembly (102), which incorporates a magnetic levitation module (104) to suspend a spherical object (106) without physical contact. The magnetic support assembly (102) functions by generating a controlled magnetic field through the magnetic levitation module (104), thereby enabling the spherical object (106) to remain in a levitated state without contact with any surrounding surfaces. This configuration eliminates friction between the object and any supporting structure, allowing the spherical object (106) to maintain a stable and unimpeded position, which is critical for high-precision printing. The magnetic levitation module (104) may use one or more permanent magnets, electromagnets, or a combination thereof to create a magnetic field that counteracts the force of gravity on the spherical object (106), thereby holding it in place. The magnetic levitation module (104) may further be designed with feedback mechanisms that dynamically adjust the magnetic field in real-time, ensuring consistent suspension of the spherical object (106) even if minor positional shifts occur. In certain embodiments, sensors integrated with the magnetic support assembly (102) can detect positional changes in the spherical object (106), and the magnetic levitation module (104) can automatically modify the magnetic field strength to re-stabilize the object as needed. The magnetic support assembly (102) may be configured concentrically with other system components, such as a rotating mechanism (108), ensuring that the spherical object (106) remains centrally aligned, thus enabling optimal rotational control for precise printing.
[00033] The system (100) further includes a rotating mechanism (108) that is integrated with the magnetic support assembly (102) and is responsible for controlling the rotation of the suspended spherical object (106) during the printing process. The rotating mechanism (108) operates by imparting a controlled rotational force on the spherical object (106), allowing it to rotate about a stabilized axis, thereby facilitating uniform material application across the entire surface of the object. In one embodiment, the rotating mechanism (108) is positioned concentrically around the magnetic support assembly (102), creating an annular arrangement that applies balanced rotational torque to the suspended spherical object (106). This configuration enables the spherical object (106) to rotate smoothly with minimal oscillation, thereby reducing the risk of print misalignment or material application inconsistencies. The rotating mechanism (108) may also include speed control elements that allow for adjustable rotation rates, accommodating various printing patterns or materials that may require specific rotation speeds for optimal results. In certain embodiments, the rotating mechanism (108) may further incorporate a stabilizing ring positioned adjacent to the magnetic levitation module (104) to dampen any vibrations within the system (100), thus enhancing the steadiness of the spherical object (106) during rotation. This stabilizing feature is particularly advantageous in high-speed printing applications, where even minor vibrations can result in print defects. The rotating mechanism (108) may be driven by a motor or other drive systems capable of delivering precise control over rotation speed and direction. Additionally, the rotating mechanism (108) is capable of bi-directional rotation, allowing the spherical object (106) to be rotated in either clockwise or counterclockwise directions as required by the printing design. The ability to control both the speed and direction of rotation enables the system (100) to apply complex patterns or multi-layered designs with high accuracy across the spherical surface.
[00034] Adjacent to the spherical object (106) and in operative alignment with the rotating mechanism (108), the system (100) includes a printhead (110) configured to apply printed material onto the surface of the spherical object (106) as it rotates. The printhead (110) is positioned to enable precise deposition of material onto the rotating spherical object (106), ensuring that the printed material is applied uniformly across the object's curved surface. In one embodiment, the printhead (110) is aligned parallel to the equatorial plane of the spherical object (106), allowing it to maintain consistent material application as the object rotates, which is essential for achieving high-resolution detail across the entire surface. The printhead (110) may comprise a multi-nozzle arrangement, allowing the simultaneous application of multiple layers or colors, thus enabling customized printing with varying textures or finishes. Each nozzle within the multi-nozzle arrangement may be independently controlled to allow for precise adjustment of material flow, ensuring consistent layer thickness and uniform color distribution. The printhead (110) may further be equipped with positioning controls that enable it to span the maximum diameter of the spherical object (106), allowing seamless coverage of the entire surface during the printing process. In some embodiments, the printhead (110) includes sensors that monitor the proximity of the printhead (110) to the spherical object (106), ensuring that the correct distance is maintained to prevent contact while optimizing print quality. This distance control is critical, as variations in proximity may lead to inconsistencies in layer thickness or material application. The printhead (110) may be connected to an ink or material reservoir that supplies the printed material through the nozzles, with flow rates controlled in real-time to achieve desired printing effects. The system (100) may also include software or control algorithms that synchronize the printhead (110) operation with the rotation speed of the spherical object (106), enabling complex designs to be printed with precision across the curved surface.
[00035] FIG. 2 illustrates a sequence diagram of a system (100) for rotational printing of a spherical object (106), which operates according to an arrangement of components configured to work in coordination for high-precision printing. The magnetic support assembly (102) initiates the process by activating the magnetic levitation module (104), which generates a magnetic field to suspend the spherical object (106) without physical contact, thereby reducing friction and preventing surface imperfections. Once levitated, the magnetic support assembly (102) engages the rotating mechanism (108), which imparts controlled rotational motion to the spherical object (106), allowing it to rotate about a stabilized axis during the printing process. As the spherical object (106) rotates, the printhead (110), positioned adjacent to the object, applies printed material onto its surface. The printhead (110) is synchronized with the rotation of the spherical object (106) to ensure precise and uniform application across the entire surface. Upon completing a full surface rotation, the system (100) achieves comprehensive coverage of the spherical object (106), ensuring high-resolution, seamless printing. This sequential interaction among components enables the system (100) to deliver consistent quality and detail in applications that require rotational printing on curved surfaces.
[00036] In an embodiment, the magnetic levitation module (104) is arranged concentrically with the rotating mechanism (108) within the system (100) to establish a stabilized axis of rotation for the spherical object (106). This concentric arrangement ensures that the spherical object (106) remains centrally aligned with the rotating mechanism (108), creating a balanced and stabilized rotational axis that minimizes lateral shifts during the printing process. By maintaining a stable axis, the magnetic levitation module (104) enhances printing accuracy, as it prevents the object from deviating from its rotational path, which could otherwise lead to distortions in the printed material. This configuration is particularly beneficial for high-precision printing applications, as it enables the spherical object (106) to rotate smoothly and steadily. The alignment created by the concentric arrangement also optimizes the interaction between the magnetic levitation forces and rotational torque, allowing the spherical object (106) to achieve consistent alignment with the printhead (110) throughout the process. This stability improves overall print quality, as the printhead (110) can apply material evenly across the object's surface without needing to compensate for shifts in object position. Such a configuration also reduces system wear and tear by minimizing the need for mechanical adjustments to correct alignment, thus enhancing the durability and operational efficiency of the system (100).
[00037] In an embodiment, the rotating mechanism (108) includes an annular arrangement positioned peripherally around the magnetic support assembly (102), which facilitates uniform rotational torque on the spherical object (106) suspended by the magnetic levitation module (104). The annular arrangement allows the rotating mechanism (108) to exert balanced force across the circumference of the spherical object (106), promoting smooth rotation with minimal oscillation. This uniform application of rotational torque is critical for precision printing, as it ensures that the object (106) maintains a steady, uninterrupted rotation, which in turn enables the printhead (110) to apply printed material accurately and consistently across the object's surface. The annular configuration of the rotating mechanism (108) is designed to reduce disturbances that could arise from uneven force distribution, thereby preventing rotational wobbling and enhancing the quality of the printed output. In certain embodiments, the annular structure may further incorporate features to modulate torque intensity based on the specific requirements of the printing application, such as altering the torque for different object sizes or adjusting for specific material properties. Additionally, the annular arrangement provides structural stability to the overall system (100), as it is positioned around the magnetic support assembly (102) and works in conjunction with the magnetic levitation forces to stabilize the object (106) without requiring physical contact. This arrangement contributes to the durability and precision of the system (100), ensuring that the spherical object (106) can rotate at controlled speeds, essential for achieving detailed and high-quality printing results.
[00038] In an embodiment, the printhead (110) is positioned in a fixed, parallel alignment with the equatorial plane of the spherical object (106), facilitating uniform application of printed material across the object's surface. Such alignment ensures that the printhead (110) is optimally positioned to apply material consistently around the widest circumference of the spherical object (106) as it rotates. This parallel orientation enables the printhead (110) to maintain an even distance from the object's surface, preventing variations in layer thickness that could arise from positional discrepancies. The fixed positioning also simplifies the printing process by allowing the printhead (110) to operate without the need for dynamic adjustments, enabling high-resolution printing of intricate designs or patterns. Additionally, aligning the printhead (110) with the equatorial plane ensures that material is applied symmetrically, reducing the risk of asymmetrical patterns or uneven color distribution. In some embodiments, the printhead (110) may feature multiple nozzles to support the application of different colors or textures simultaneously, enhancing the aesthetic quality and versatility of the printed output. The fixed alignment with the equatorial plane is particularly beneficial for designs that require precise control over material placement, such as logos or detailed imagery, as it allows the printhead (110) to cover the surface accurately as the rotating mechanism (108) turns the spherical object (106) around its stabilized axis.
[00039] In an embodiment, the magnetic support assembly (102) and the printhead (110) are aligned longitudinally, allowing the printhead (110) to span the maximum diameter of the spherical object (106). This longitudinal alignment optimizes the coverage area of the printhead (110) across the object (106), enabling a seamless printing process that effectively covers the entire surface without leaving gaps or inconsistencies. By positioning the printhead (110) to span across the widest portion of the spherical object (106), the system (100) achieves full-surface printing, ensuring that even the extremities of the object are reached. This alignment also enables the printhead (110) to operate efficiently, as it minimizes the need for multiple passes over the same area, thereby reducing processing time and improving production efficiency. Furthermore, the

longitudinal alignment between the magnetic support assembly (102) and the printhead (110) provides a stable configuration that enhances control over material application. This arrangement allows for greater precision in layer thickness and color uniformity, which is essential for high-quality printing on spherical surfaces. Additionally, the longitudinal alignment aids in maintaining the structural integrity of the system (100), as it reduces the risk of misalignment that could lead to printing errors or defects, thereby contributing to consistent and reliable operation.
[00040] In an embodiment, the rotating mechanism (108) includes a stabilizing ring positioned adjacent to the magnetic levitation module (104) to minimize vibrations within the system (100) during the printing process. The stabilizing ring provides structural support, ensuring that the spherical object (106) remains steady while rotating, which is critical for achieving accurate and high-quality printing. By dampening vibrations, the stabilizing ring reduces the risk of rotational deviations or oscillations that could compromise the precision of the printhead (110) application. This vibration reduction is particularly beneficial for intricate designs that require consistent layer thickness and detail across the entire surface of the spherical object (106). In certain embodiments, the stabilizing ring may be made from materials with vibration-absorbing properties, such as rubber or specialized polymers, further enhancing its ability to maintain stability. The placement of the stabilizing ring in close proximity to the magnetic levitation module (104) allows it to work in conjunction with the magnetic field, creating a cohesive support structure that maximizes stability. This configuration ultimately enhances the durability and efficiency of the system (100), as it prevents mechanical wear caused by excessive movement, thereby contributing to long-term operational reliability.
[00041] In an embodiment, the printhead (110) comprises a multi-nozzle arrangement that enables the application of varied layers of printed material onto the spherical object (106). This multi-nozzle configuration provides the flexibility to apply different types of materials, colors, or textures, allowing customization at each layer for enhanced durability and aesthetic quality. Each nozzle within the arrangement may be individually controlled, enabling precise adjustments in flow rate, material thickness, and composition for each layer of application. This setup allows the system (100) to create multi-layered designs with distinct material properties, such as increased abrasion resistance or specific color effects, which is beneficial for applications that demand high-quality finishes. In certain embodiments, the multi-nozzle arrangement may include dedicated nozzles for base layers, mid-layers, and top coats, ensuring that each section of the spherical object (106) receives the appropriate treatment for desired durability and appearance. This configuration enhances the versatility of the system (100), making it suitable for complex printing tasks that require precise control over each layer's characteristics.
[00042] In an embodiment, the rotating mechanism (108) is equipped with a rotational speed control module, which allows adaptive adjustments to the rotation rate of the spherical object (106) based on the complexity of the printing patterns. This speed control capability ensures that the object (106) rotates at a rate that aligns with the specific requirements of the printhead (110) application, maintaining uniform layer application regardless of rotational velocity. The rotational speed control module may include sensors that monitor the object's position and adjust rotation speed dynamically in real-time, accommodating changes in design complexity or material viscosity. For example, intricate patterns or multi-layer designs may require slower rotation to allow the printhead (110) to deposit material accurately, while simpler patterns may benefit from faster rotation to improve efficiency. This flexibility in speed adjustment enhances the precision and quality of the printed material, as it ensures that each section of the spherical object (106) receives the required attention based on design requirements.
[00043] In an embodiment, the magnetic support assembly (102) comprises an electromagnetic feedback control system configured to dynamically adjust the magnetic field strength, thereby compensating for any positional deviations of the spherical object (106) to maintain precise levitation throughout the printing process. This feedback control system operates by monitoring the position of the spherical object (106) in real time, using sensors to detect any shifts or variations in its alignment. When positional deviations are detected, the feedback control system instantly adjusts the magnetic field generated by the magnetic levitation module (104), ensuring that the object (106) remains stably suspended at a fixed position and does not interfere with the rotation or printing. This capability is essential for maintaining a high level of print accuracy, as even minor positional shifts could result in misalignments that affect layer consistency and detail precision. The feedback system thus provides a robust solution for continuous stability, allowing the system (100) to operate efficiently with minimal manual intervention, thereby enhancing the reliability and quality of the printing process on spherical objects. In an embodiment, magnetic support assembly (102) comprising magnetic levitation module (104) creates a frictionless environment by suspending spherical object (106) without physical contact. This suspension eliminates mechanical interference, enabling consistent alignment and reducing surface imperfections that could arise from physical supports. By preventing direct contact, magnetic levitation module (104) minimizes wear on the spherical object (106) and allows smoother, uninterrupted rotation, which is essential for precise and high-quality printing. The non-contact levitation mechanism also contributes to greater longevity of the system (100) by reducing maintenance requirements associated with traditional mechanical supports.
[00044] In an embodiment, magnetic levitation module (104) is arranged concentrically with rotating mechanism (108), resulting in a stabilized axis of rotation for spherical object (106). This concentric arrangement ensures the object (106) remains aligned along a central rotational axis, which prevents lateral shifts that could otherwise disrupt print accuracy. This stabilized axis enhances the uniformity of material application by allowing printhead (110) to consistently apply material across the object (106) without adjusting for positional misalignment. As a result, the concentric arrangement improves precision and reduces the risk of print defects caused by uneven rotation.
[00045] In an embodiment, rotating mechanism (108) includes an annular arrangement around magnetic support assembly (102), providing uniform rotational torque on spherical object (106). The peripheral positioning of the annular arrangement minimizes oscillations, allowing the object (106) to rotate steadily with minimal vibration, which is essential for accurate material application by printhead (110). The uniform torque distribution enhances print quality by preventing rotational imbalances that could lead to irregularities in layer thickness or pattern accuracy. This configuration supports high-resolution printing across the entire surface of the spherical object (106).
[00046] In an embodiment, printhead (110) is aligned in a fixed, parallel orientation to the equatorial plane of spherical object (106). This alignment allows printhead (110) to maintain an optimal distance from the object's surface throughout the rotation, which ensures even layer application across the widest circumference of the object (106). The parallel positioning enhances printing precision by providing consistent material deposition, resulting in high-resolution detail across the rotational surface. By reducing variability in layer thickness, this configuration enhances print quality and minimizes errors in complex or intricate designs.
[00047] In an embodiment, magnetic support assembly (102) and printhead (110) are positioned in a longitudinal alignment, allowing printhead (110) to span the maximum diameter of spherical object (106). This alignment enables printhead (110) to cover the entire surface of object (106) without requiring multiple passes, facilitating a seamless and continuous printing process. By spanning the maximum diameter, this configuration reduces processing time and eliminates potential gaps or inconsistencies in material application. The longitudinal alignment thus improves operational efficiency and ensures that the entirety of spherical object (106) is uniformly covered.
[00048] In an embodiment, rotating mechanism (108) includes a stabilizing ring adjacent to magnetic levitation module (104), which provides structural support to minimize vibrations within system (100). The stabilizing ring enhances rotational steadiness of spherical object (106) by damping vibrations that could lead to rotational deviations during the printing process. This stability is particularly important for maintaining high print quality, as it prevents misalignment that could result in uneven application of material. The stabilizing ring therefore supports precision printing by ensuring the object (106) remains steady, contributing to a consistent and defect-free printed surface.
[00049] In an embodiment, printhead (110) incorporates a multi-nozzle arrangement, allowing for the application of varied layers of printed material on spherical object (106). This configuration enables customization of each printed layer, supporting properties such as enhanced durability or specific aesthetic effects. Each nozzle in the multi-nozzle arrangement can be controlled independently, allowing different materials or colors to be applied simultaneously. This feature improves flexibility in design and quality, enabling complex, multi-layered patterns that enhance the overall functionality and visual appeal of the printed object (106).
[00050] In an embodiment, rotating mechanism (108) is integrated with a rotational speed control module, allowing adaptive adjustments to the rotation rate of spherical object (106) according to the complexity of the printing patterns. This speed control ensures that rotation speed matches the demands of intricate designs, where slower speeds may be necessary for accuracy, while faster speeds can be used for simpler patterns. By adjusting rotational velocity based on design requirements, this feature supports uniform application across varying pattern densities, ensuring each layer is consistently applied, regardless of complexity.
[00051] In an embodiment, magnetic support assembly (102) includes an electromagnetic feedback control system that dynamically adjusts magnetic field strength to maintain precise levitation of spherical object (106). This control system detects positional deviations and compensates by adjusting the magnetic field in real time, ensuring that the object (106) remains stably suspended during rotation. By continuously monitoring and correcting object position, the feedback control system prevents shifts that could lead to print misalignment, enhancing both accuracy and reliability of the printing process. This capability supports consistent print quality and operational stability.
