[0020] As used herein, the singular forms "a," "an," and "the" designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to an automated circular wooden bangle carving device that is capable of manufacturing a wooden bangle as per the user specified diameter as well as maintaining cleanliness and hygiene in surrounding of the device while carving the bangle.

[0022] Referring to Figure 1 and figure 2, an isometric view of an automated circular wooden bangle carving device and a bottom view of a platform associated with the proposed device is illustrated, comprising a circular platform 101 positioned on the workpiece, a telescopic rod 102 configured with the platform 101, a suction cup 103 attached with a free-end of the rod 102, a touch interactive display panel 104 mapped on the platform 101, an inverted L-shaped telescopic link 202 suspended from the platform 101, an inverted U-shaped cutting unit 107 attached with the link 202, a motorized circular sliding arrangement 204 coupled between the link 202 and platform 101, an artificial intelligence-based imaging unit 201 mounted on the platform 101, a robotic link 203 configured with an abrasive sheet 205 and install on the platform 101, a speaker 105 mapped on the platform 101, cleaning unit 106 is configured on the platform 101, a receptacle 206 integrated within the cleaning unit 106.

[0023] The proposed invention is comprises a circular platform 101 configured with a telescopic rod 102 and developed to be positioned by a user manually on a wooden workpiece, wherein the platform 101 is cast with highly durable materials and is rigid in nature with a flat cuboidal shape, offering a large space to accommodate multiple mechanical and electrical units. The platform 101 is constructed from sturdy and robust materials that may include but not limited to stainless steel, aluminum. These materials offer rigidness and robustness to the platform 101 making the platform 101 resistant to mechanical stress and pressure.

[0024] Further, a suction cup 103 is attached with free-end of the rod 102 for affixing with surface of the workpiece. The suction cup 103 are consist of a circular disc which are made of a flexible material mostly rubber with a rounded edge, whenever the pressure is applied by the concerned person in the center of the disc, a concave shape is generated and when the cup 103 is forced against surface of the workpiece a vacuum is created in the cup 103 which causes the cup 103 to stick strongly with the surface of the wooden workpiece to attain stability for further process on the workpiece.

[0025] Upon affixing with surface of the workpiece, an inbuilt microcontroller activate an ultrasonic sensor mapped on the platform 101 for detecting height of the user. The ultrasonic sensor works by generating ultrasonic waves, wherein the waves hit the user's body and are diffracted back. The diffracted waves are received by a receiver integrated within the sensor. The pattern of the received waves gets converted into an analogue value which is further converted into an electrical signal, wherein the electrical signal is send to the microcontroller. The microcontroller then processes the received signal from the sensor, thus detecting height of the user in accordance to which the microcontroller evaluates height of the platform 101 is to be extend for the user convenient.

[0026] Upon determining the height of the user, the microcontroller actuate the rod 102 to position the platform 101 at an optimum height. The extension of the rod 102 is powered by a pneumatic unit associated with the device and includes an air compressor, air cylinder, air valves and piston. The air compressor used herein extract the air from surrounding and increases the pressure of the air by reducing the volume of the air. The air compressor is consist of two main parts including a motor and a pump. The motor propels the compressor pump which uses the energy from the motor drive to draw in atmospheric air and compress to elevated pressure. The compressed air is then sent through a discharge tube into the cylinder across the valve. The compressed air in the cylinder tends to pushes out the piston to extend the rod 102 to position the platform 101 at the optimum height.

[0027] Upon positioning the platform 101 at optimum height, the microcontroller activate a touch interactive display panel 104 mapped on the platform 101 for enabling the user to input details regarding diameter of a bangle that the user desires to manufacture. The display panel 104 consists of tiny wires that complete a circuit when connected by the touch of the user while providing the input data. The input data is registered within a database of an inbuilt microcontroller associated with the device for processing the input data given by the user.

[0028] As per the user command, the microcontroller activate an inverted L-shaped telescopic link 202 suspended from the platform 101 to position an inverted U-shaped cutting unit 107 attached with the link 202. The link 202 operate on the same principle as that the rod 102 disclosed above, thus the link 202 get extend and position the cutting unit 107 over the workpiece.

[0029] Upon positioning the cutting unit 107 over the workpiece, the microcontroller activate a touch sensor installed on the cutting unit 107 for detecting placement of the cutting unit 107 on the workpiece. The touch sensor works as a switch, such that when the sensor is subjected to the contact of the cutting unit 107, the sensor gets activated and work as a closed switch that allows the flow of current through the circuit. The current is sent to the microcontroller linked with the sensor in the form of data. The microcontroller then processes the detected data and determines the placement of the cutting unit 107 on the workpiece.

[0030] Upon determining the positioning of the cutting unit 107 on the workpiece, the microcontroller activate an IR (Infrared) sensor is mapped on the platform 101 for detecting surface texture of said workpiece. The IR (infrared) sensor consists of an IR emitter and an IR receiver. The emitter emits infrared light towards the surface of the workpiece and are bounced back from the workpiece and returns to the receiver. The sensor then sends an electrical signal to the microcontroller for processing and based on which the microcontroller process the signal and compared with pre-fed database and evaluate the surface texture of said workpiece .

[0031] In case any wooden spikes or bents are detected, the microcontroller activate a speaker 105 mapped on the platform 101 for generating audio alerts to notify the user regarding the low quality of workpiece. The speaker 105 works by receiving signals from the microcontroller, converting them into sound waves through a diaphragm's vibration, and producing audible sounds with the help of amplification and control circuitry in order to notify the user to replace the present workpiece with an another workpiece of good quality.

[0032] Further, the microcontroller actuates a motorized sliding arrangement 204 coupled between the link 202 and platform 101 for providing rotational motion to the link 202. The motorized sliding arrangement 204 incorporates an electric motor to drive a circular movement of the link 202 along a track. Upon actuation of the sliding unit by the microcontroller, the motor's power is harnessed to move the slider in an automated and precise way for a smooth and controlled rotational motion of the link 202 over the workpiece. Simultaneously, actuation of the link 202 for extending gradually that aids in cutting of the workpiece.

[0033] Thereafter, the microcontroller actuate the motorized cutter unit to cut the workpiece in a shape of user specified diameter. The motorized cutter consists of motor connected to a set of blades for cutting the workpiece. The motor is the key component that converts electrical energy into mechanical energy to provide movement to the blade. Upon actuation of the cutter by the microcontroller, the motor starts rotating the blades in a clockwise/anti-clockwise direction by imparting the rotational motion to the blades thus cutting the workpiece of the user specified diameter.

[0034] Upon cutting workpiece of the user specified shape, the microcontroller activate an artificial intelligence-based imaging unit 201 mounted on the platform 101 to determine successful manufacturing of the bangle. The imaging unit 201 comprises of an image capturing arrangement 204 including a set of lenses that captures multiple images of the workpiece and the captured images are stored within a memory of the imaging unit 201 in form of an optical data. The imaging unit 201 also comprises of a processor that is integrated with artificial intelligence protocols, such that the processor processes the optical data and extracts the required data from the captured images. The extracted data is further converted into digital pulses and bits and are further transmitted to the microcontroller. The microcontroller processes the received data and determines successful manufacturing of the bangle.

[0035] Simultaneously, the microcontroller actuate a robotic gripper attached with the platform 101 for gripping the bangle from the workpiece. The robotic gripper includes a pole connected with multiple motorized ball and socket joints and a gripper for smooth and precise gripping of bangle.

[0036] The motorized ball and socket joint includes a motor powered by the microcontroller generating electrical current, a ball shaped element and a socket. The ball move freely within the socket. The motor rotates the ball in various directions that is controlled by the microcontroller that further commands the motor to position the ball precisely. The microcontroller further actuates the motor to generate electrical current to rotate in the joint for providing movement to the gripper for gripping and extracting the bangle from the workpiece.

[0037] Upon extracting the bangle from the workpiece, the microcontroller activate a LiDAR (Light Detection and Ranging) sensor installed on the platform 101 and synced with the imaging unit 201 for detecting presence of any uneven surface on the manufactured bangle. The LiDAR sensor sends out rapid laser pulses in a sweeping motion towards bangle for detecting defected bangle. These pulses travel through the air and interact with the surface of the bangle. When the laser pulses encounter the bangle, the laser bounces off from the surface of the bangle. The LiDAR sensor precisely measures the time takes for these laser pulses to travel to the surface of the bangle and back to the sensor and calculations is performed by the sensor based on the time interval between the sending signal and receiving echo to determine uneven surface on the bangle.

[0038] In case the uneven surface is detected on the bangle, the microcontroller actuate a robotic link 203 configured with an abrasive sheet 205 and configured on the platform 101 for rubbing the sheet 205 on the manufactured bangle. The robotic link 203 is operated on the same principle as that the robotic gripper disclosed above, thus the robotic link 203 position the abrasive sheet 205 on the bangles which have uneven surface and move the sheet 205 over the surface accordingly for rubbing the sheet 205 on the manufactured bangle that aids in smoothening of the bangle and elimination of uneven surface from the bangle.

[0039] Additionally, a vacuum based cleaning unit 106 is configured on the platform 101 that is actuated by the microcontroller to withdraw wood dust generated from cutting of the workpiece. The cleaning unit 106 operates on the principle of creating a vacuum to generate negative pressure within a cleaning unit 106. This is facilitated by a combination of components: the pliable suction cup 103 forms an airtight seal against the ring, while a piston mechanism enables controlled movement for
extension and retraction. When activated, a vacuum pump removes air from the space between the cup 103 and the ring, causing the cup 103 to adhere firmly. This synchronized action allows the cleaning unit 106 to securely withdraw wood dust from the working station and stored in a receptacle 206 integrated within the cleaning unit 106.

[0040] Lastly, a battery is installed within the device which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is generally a dry battery which is made up of Lithium-ion material that gives the device a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the device is battery operated and do not need any electrical voltage for functioning. Hence the presence of battery leads to the portability of the device i.e., user is able to place as well as moves the device from one place to another as per the requirements.

[0041] The proposed device is work well in the following manner, where the platform 101 as disclosed in the invention is configured with the telescopic rod 102 and placed over the workpiece by the user. Further, the ultrasonic sensor detect the height of the user, based on which the microcontroller actuate the rod 102 for positioning the platform 101 at an optimum height as per the user convenient. Thereafter, the microcontroller activate the touch interactive display for the user input regarding diameter of the bangle. As per the user input, the microcontroller activate the telescopic link 202 to position the cutting unit 107 over the workpiece. Then, the IR (Infrared sensor) determine quality of the workpiece and in case the quality is low, the microcontroller actuate the speaker 105 to notify the user to change the workpiece accordingly. After then, the touch sensor detect the placement of the cutting unit 107 over the workpiece. Then, the microcontroller actuate the sliding arrangement 204 to rotate the link 202 and also change cutting unit 107 as per the user specified diameter of the bangle followed by actuation of the links for extending gradually that aids in cutting of the workpiece. Upon complete manufacturing of the bangle, the microcontroller activate the artificial intelligence-based imaging unit 201 determines successful manufacturing of the bangle. Simultaneously the microcontroller actuates a robotic gripper for gripping and extracting the bangle from the workpiece. Upon extracting the bangle from the workpiece, the LiDAR (Light Detection and Ranging) sensor to detect the presence of any uneven surface on the manufactured bangle. In case the uneven surface is detected, the microcontroller actuates a robotic link 203 integrated with abrasive sheet 205 for rubbing the sheet 205 on the manufactured bangle in view of smoothening of the bangle and elimination of uneven surface from the bangle. Upon completion of the bangle manufacturing processes, the microcontroller actuate the cleaning unit 106 to withdraw wood dust and stored in a receptacle 206.
