Specification

Description:FIELD OF THE INVENTION

[0001] The present invention relates to an automated PPF (paint protection film) applying device that is capable of facilitating a user in automatically layering of a paint protection film (PPF) over outer body of a vehicle in order to save time and manual efforts along with enhancing precision. In addition, the proposed device is capable of monitoring presence of contaminants including dust, stains, scratch, swirl and oxidation dirt on vehicle's body without any manual inspection, and also providing means to remove the contaminants.

BACKGROUND OF THE INVENTION

[0002] Generally, people used to drive vehicles in their usual lives for travelling or for moving from one location to another in an efficient manner. Correspondingly, they apply a paint protection film sheet on their vehicle for protecting their
vehicle from road debris, stone chips and other potential damage. Paint
Protection Film is a transparent, self-healing film that helps in maintaining
the appearance of the vehicle's paint by preventing scratches and chips. This
PPF is install on the outer body of the vehicle, basically in the workstations.
Thereby, workers that work in the work station use to install the paint
protection film sheet manually via using some handy tools like squeegees or
heat gun. These tools help workers to install the PPF efficiently, however
these tools take a lot of physical efforts as well as installing PPF with such
tools are time consuming. Thus, they use an equipment that install the paint
protection film efficiently within less period of time and less physical
efforts.

[0003] Some conventional ways were used by the workers for installing a paint protection film within outer body of a vehicle. They usually install the paint protection film sheet manually via using some handheld tools like squeegee or applicator tool. This is basically a handheld tool with a soft, smooth edge and is used to smooth out and press the film on to the vehicle surface via eliminating air
bubbles and ensuring proper adhesion. However, using such tools for installing
paint protection film on a vehicle is time consuming, also these tools are less
efficient. Thereby, they use some tools that install the paint protection film
in a more efficient manner and within less time, as the workers afterwards uses
laser alignment tool. This tool ensures precise placement and alignment of the
PPF on the vehicle's body. But a skilled worker is required for operating such
tool efficiently.

[0004] CN215278222U discloses about an invention that includes a protective film coating device which comprises a processing table and a coating machine arranged above the processing table, the outer side of

Additionally, these existing devices also lack in determining presence of the dust over the surface of the outer body and are insufficient in removing the dust from the body.

[0006] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a device that is capable of fixing paint protection film
within outer body of a vehicle in accordance with specified dimension of the
vehicle, in an effective manner. Correspondingly, the device also assesses the
amount of paint protection film sheet that is required for covering outer body

[0019] 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.

[0020] The present invention relates to an automated PPF (paint protection film) applying device that is capable of automatically sheathing a paint protection film (PPF) over outer body of a vehicle in view of reducing manual efforts and time. In addition, the proposed device is capable of determining contaminants including dust, stains, scratch, swirl and oxidation dirt on vehicle's body without any manual inspection, and also providing means to remove the contaminants.

[0021] Referring to Figure 1 and Figure 2, an isometric view of an automated PPF (paint protection film) applying device and an isometric view of a detachable roller associated with the proposed device are illustrated, respectively comprising a platform 101 developed to be positioned on a ground surface, a microphone 102 is configured with the platform 101, an artificial intelligence-based imaging unit 103 installed on the platform 101, plurality of motorized wheels 104 arranged underneath the platform 101, a water chamber 105 is attached to the platform 101 and integrated with an electronically controlled valve 106, a pair of motorized grippers 107 installed on the platform 101, a box 108 positioned on the platform 101, a robotic arm 109 installed on the platform 101, a motorized buffing pad 110 configured with the arm, a detachable roller 201 is attached on the platform 101 and wrapped with a PPF (paint protection film) sheet, a motorized blade 202 configured in proximity to the roller 201, an electronically controlled nozzle 111 installed on the platform 101 via a receptacle 112 integrated on the platform 101 and a speaker 113 installed on the platform 101.

[0022] The proposed device comprises of a platform 101 101 which is positioned on a ground surface in proximity to a vehicle over which a user is desiring to layer a PPF (paint protection film) sheet. The platform 101 is developed a protective exterior of the device and the components associated with the device are mounted over the platform 101. The platform 101 is preferably rectangular in shape and made up of stainless steel that offers a corrosion resistant, strength and durability to the device and is easy to maintain. Initially the user is required to access a microphone 102 configured with the platform 101 to provide voice command to activate/deactivate the device. The microphone 102 works by converting sound waves into electrical signals.

[0023] The microphone 102 is designed to detect variations in air pressure caused by user's voice in the surrounding and transform those pressure fluctuations into electrical signals that is further processed, stored, or transmitted to the microcontroller. Whenever, the user speaker 113, it creates a series of compressions and rarefactions in the surrounding medium, which constitute sound waves. The microphone 102 typically consists of a diaphragm, a magnet, and a coil. The diaphragm is a thin, flexible membrane that vibrates in response to the changes in air pressure caused by sound waves in the housing.

[0024] When the diaphragm vibrates, it moves the coil relative to the magnet, inducing an electric current in the coil due to electromagnetic induction. As the coil moves within the magnetic field of the sensor, it generates a varying electrical voltage proportional to the diaphragm's motion. This voltage represents the electrical analog of the sound waves and is often referred to as the audio signal. The electrical signal is amplified and converted into an analog electrical signal which is processed by the microcontroller. After processing the microcontroller fetches the user's voice input.

[0025] After receiving the command, the microcontroller actuates an artificial intelligence based imaging unit 103 installed on the platform 101 for evaluating a three dimensional mapping of the vehicle. The imaging unit 103 comprises of a processor and a camera which on actuation capture the multiple image of the surrounding. The camera is comprised of a lens and a digital camera sensor, wherein the camera lens takes all the light rays rebounding around the surrounding and utilizes the lenses to transmit them to a single point for creating a sharp image. When all of those light rays rebound back and meet together on a digital camera sensor, create a digital image of the surrounding by performing various operations like pre-processing, feature extraction and classification which is transmitted to the processor. The processor further extracts all the required information from the digital images and transmit to an inbuilt microcontroller associated with the device, which further processes the information shared by the processor in order to evaluate the mapping of the vehicle.

[0026] Further, the evaluated mapping is displayed over a computing unit of the user, for enabling the user to select a portion over which the sheet is to be layered. The computing unit is wirelessly linked with a microcontroller via a communication module which includes but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module employed herein acts as an intermediate between various electronic components, wherein the module is used to establish the communication between the user's computing unit and the microcontroller. The customized Global System for Mobile communication (GSM) module is designed for establishing a wireless connection between computing unit and the microcontroller. This module is able to receive serial data from radiation monitoring devices such as computing unit and transmit the data to microcontroller.

[0027] After receiving the input regarding a portion to be applied with sheet, the microcontroller actuates plurality of motorized wheels 104 (preferably four in number) arranged underneath the platform 101, to move the platform 101 towards the specified portion of the vehicle. The motorized wheels 104 are a circular object that revolves on an axle to enable the body to move easily over the ground surface. For maneuvering the platform 101 each of the wheels 104 need to rotate and which is governed by a hub motor fit in the hub of each of the wheels 104. The hub motor is an electric motor that is integrated into the hub of the wheels 104.

[0028] The hub motor comprises of a series of permanent magnets and electromagnetic coils. When the motor is activated, a magnetic field is set up in the coil and when the magnetic field of the coil interacts with the magnetic field of the permanent magnets, a magnetic torque is generated causing the stator of the motor to turn and that provides the rotation motion to the wheels 104 for maneuvering the platform 101 on the ground surface for positioning platform 101 near specified portion. As soon as the platform 101 gets positioned in close proximity to the specified portion as detected by the imaging unit 103, the microcontroller via a dust sensor which is integrated on the platform 101 and in synced with the imaging unit 103, determines presence and location of contaminants including dust, stains, scratch, swirl and oxidation dirt on the specified portion.

[0029] The dust sensor used herein is based on an optical sensing method to detect dust. The dust sensor consists of a photo sensor and an infrared light-emitting diode (IR LED). The IR- LED emits the IR rays on the user-specified portion on the vehicle and the photo-sensor receive the reflected IR LED rays from the user-specified portion on the vehicle. The reflected rays and the visuals from the imaging unit 103, are processed by the microcontroller to detect the presence of the contaminants over the user-specified portion on the vehicle.

[0030] A water chamber 105 is attached to the platform 101 and dedicated to store water. If the dust is detected to be accumulated over the specified portion, then the microcontroller actuates an electronically controlled valve 106 integrated on the chamber 105 to dispense water on the specified portion detected with dust for removing the dust from specified portion of vehicle. The electronically controlled valve 106 used herein consists of a gate and magnetic coil, which on energizing generates magnetic force to push the gate to open and allowing the water to be dispensed over the specified portion in order to clean the dust.

[0031] A box 108 positioned on the platform 101 and stored with multiple clay bars. If the specified portion is detected to be accumulated with stains, then the microcontroller actuates a pair of motorized grippers 107 installed on the platform 101 to grip one of clay bar stored from box 108 and rub gripped clay bar over the specified portion along with dispensing of water to remove the contaminants from the vehicle. The motorized grippers 107 contains a robotic link and an end effector which is installed at free end of the link. The robotic link is made of several segments that are attached together by joints also referred to as axes. Each joint of the segments contains a step motor that rotates and allows the robotic link to complete a specific motion in translating the equipped effector towards the box 108.

[0032] Further, the step motor, is a kind of motor which rotates in small, precise steps, unlike other motors which rotates continuously. The step motor comprises of a rotor and stator. The rotor is the rotating part of the motor, and the stator is the stationary part. The stator consists of multiple conducting coils of wire which are arranged in a specific manner.

[0033] When current flows through the coils, the magnetic field is setup around the coil and that cause the rotor to move in precise steps to translate the link towards the box 108 for positioning the end effector in contact with clay bars. Further the end effector comprises of a pair of jaws assembled with each other by means of another step motors which enables the opening/closing of the jaws in order to grip one of the bar from the box 108 and after gripping the microcontroller directs the grippers 107 again for rubbing the bars on the detected stain along with dispensing of water to remove the contaminants from the vehicle.

[0034] If the specified portion is detected to be accumulated with a scratch, swirl and oxidation dirt then the microcontroller actuates a robotic arm 109 installed on the platform 101 to position a motorized buffing pad 110 configured with the arm over the detected scratch, swirl and oxidation dirt. The robotic arm 109 contains several segments that are attached together by motorized joints also referred to as axes. Each joints of the segments contains a step motor that rotates and allows the robotic arm 109 to complete a specific motion in translating the equipped buffing pad 110 over the detected scratch, swirl and oxidation dirt.

[0035] As soon as the pad 110 gets positioned over detected scratch, swirl and oxidation dirt as detected by the imaging unit 103, then the microcontroller actuates the buffing pad 110 to rotate over the location on the vehicle's surface for removing the scratch, swirl and oxidation dirt. The buffing pad 110 comprises of an electric motor and a buffing disc is coupled with a spindle. On actuation the motor rotates the disc and the disc is composed of abrasive grains bonded together in a specific shape. As the rotating disc comes into contact with the scratch, swirls or oxidation dirt, the abrasive grains on the disc grind away small particles to remove scratch, swirls or oxidation dirt.

[0036] Further post cleaning, the microcontroller via a laser measurement sensor which is integrated on the platform 101 and synched with the imaging unit 103, determines dimension of the specified portion. The laser measurement sensor is a type of non-contact sensor which is mostly being used as an electrical measurement instrument. The laser measurement sensor is based on the reflection of the laser beams. The laser measurement sensor consists of a laser emitter and a receiver. On actuation the laser emitter emits multiple beams on the specified portion, which creates a spot on the specified portion. After reflection of the beam on the specified portion, the beams got reflected back and received by the receiver in form of optical signals. A photoelectric converter in the receiver converts the optical signal into electrical signal which is detected and processed by an inbuilt microcontroller for determining the dimension of the specified portion.

[0037] A detachable roller 201 is attached on the platform 101 and wrapped with a PPF (paint protection film) sheet. In accordance to the determined dimension of user-specified portion the microcontroller actuates both grippers 107 to grip a free end of sheet and pull the end in view of unwrapping the sheet from the roller 201 as per the determined dimension of the user-specified portion. As soon as the suitable length of the sheet gets unwrapped, then the microcontroller actuates a motorized blade 202 configured in proximity to the roller 201 for cutting the sheet.

[0038] The motorized blade 202 is preferably a motorized scissor which comprises of a pair of blades which are laid one on top of the other and fastened in the middle by means of a motorized hinge. The motorized hinge is a piece of metal that joins the blades together and allows it to be deployed by revolving along the longitudinal axis whose operation is governed by a bi-directional motor that is linked with the microcontroller. When the motor rotates, then the motor provides movement to the hinge followed by which the blades also rotate so as to allow the blades to be opened and closed for cutting the sheet.

[0039] Post cutting of the sheet, the microcontroller actuates an electronically controlled nozzle 111 installed on the platform 101 to dispense a soap solution stored in a receptacle 112 arranged on the platform 101, on the specified portion of the vehicle for layering the solution on the specified portion of the vehicle. The nozzle 111 used herein consists of a gate and magnetic coil, which on energizing generates magnetic force to push the gate to open and allowing the soap solution to be dispensed over the user-specified portion and followed by actuation of both grippers 107 for alignment of the cut sheet on the specified portion of the vehicle, over the layered solution.

[0040] Post alignment of the sheet over user-specified portion, the microcontroller actuates an articulated link installed on the platform 101 for translating a wiping plate configured with the link, on the aligned sheet for applying pressure on the aligned sheet which results in applying of the sheet on the vehicle's surface along with removing the soap solution. The working of the articulated link in same as of the robotic arm 109. During the exertion of pressure on the sheet, if the microcontroller via the imaging unit 103 detects any wrinkles or bubbles on the applied sheet then the microcontroller directs the robotic link to apply optimum intensity of pressure via the wiping plate to remove the wrinkle and bubbles.

[0041] Throughout the sheet application process, an ultrasonic sensor which is integrated with the platform 101 and in synchronization with the imaging unit 103, monitors length of sheet remaining over the roller 201. The ultrasonic sensor emits high-frequency waves in vicinity of the roller 201 and measures the time it takes for the waves to bounce back after hitting the sheet wrapped over roller 201. The ultrasonic sensor collects a significant amount of data by scanning the entire roller 201 and forms a 3D point cloud, which represents the length of sheet remaining over the roller 201. The ultrasonic sensor sends the data to microcontroller which processes the acquired data and detects the length of sheet and on receding of the detected length beyond a threshold limit, the microcontroller actuates a speaker 113 installed on the platform 101 to generate audible suggestions to change the roller 201.

[0042] During the applying of sheet over the specified portion, the microcontroller via a rust detection sensor which is installed on the platform 101, determines presence of a rust on the surface of vehicle and if the rust is detected to be present then then the microcontroller actuates the speaker 113 to notify the user regarding the detected rust. The corrosion/rust detection sensor used herein is preferably ultrasonic corrosion sensor which consists of an ultrasonic wave emitter, receiver and a sensing module. Upon actuation, the emitter sends the ultrasonic waves on the mast and the waves which are reflect back is received by receiver. The sensing module analyze the reflected back waves and based on the reflected waves, the sensing module determine the level of rust present on mast. After that the sensing module converts the determined data into the form of electrical signal and transmits to the microcontroller.

[0043] Moreover, a weight sensor is embedded in each the water chamber 105, receptacle 112 and box 108 for monitoring quantities of the water, soap solution and the clay bars, respectively. The weight sensor consists of a piezoelectric measuring coil which converts the pressure applied on the coil due to weight of water, soap solution and the clay bars into electric pulse by using the principle of piezoelectricity. Further the microcontroller processes the electric pulse in order to detect the amplitude of the pulse and based on the amplitude the weight of the water, soap solution and the clay bars are detected. On receding of the determined quantities beyond a threshold level, the microcontroller sends a notification to the computing unit to notify the user to refill the chamber 105, receptacle 112 and the box 108.

[0044] A battery (not shown in figure) is associated with the device to supply power to electrically powered components which are employed herein. The battery is comprised of a pair of electrodes named as a cathode and an anode. The battery uses a chemical reaction of oxidation/reduction to do work on charge and produce a voltage between their anode and cathode and thus produces electrical energy that is used to do work in the device.

[0045] The present invention works well in the following manner where the platform 101 positioned on the ground surface in proximity to the vehicle as disclosed in the proposed invention is fabricated with the microphone 102 for allowing the user to activate/deactivate the device. Now, the artificial intelligence-based imaging unit 103 evaluates a three-dimensional mapping of the vehicle and the mapping is then displayed over computing unit for enabling the user to specify a portion on the vehicle's surface to be wrapped with the PPF (paint protection film) sheet.
