[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 leather surface maintenance device that provides a means to the user in maintaining the leather surface by creating a versatile solution that handles the entire leather repair process, from damage detection to material application.

[0022] Referring to Figure 1, an isometric view of an automated leather surface maintenance device is illustrated, comprising a body 101 developed to be positioned on a ground surface, plurality of motorized wheels 102 are provided underneath the body 101, an artificial intelligence-based imaging unit 103 is mounted on the body 101, a multi-sectioned chamber 104 installed on the body 101 having a first and second section, a robotic arm 105 installed on the body 101 for acquiring grip of an electronically controlled nozzles 106 configured with the second section, a flap 107 installed on the body 101 by means of an extendable rod 108, a motorized ball and socket joint 109 is integrated in between the rod 108 and flap 107, a robotic clipper 110 installed on the body 101, a robotic link 111 installed on the body 101, a motorized cutter 112 arranged on the link 111.

[0023] The proposed device comprises of a body 101 developed to be positioned on a ground surface. The device is made up of stainless steel that offers corrosion resistance, strength and durability to the device and is easy to maintain. A push button is integrated in the device for activating or deactivating the device. The user manually pushes the button, when the button is pressed the electrical circuit gets completed, allowing flow of electric current to actuates a microcontroller associated with the device that regulates the working of the device.

[0024] The body 101 is configured with multiple motorized wheels 102 for providing maneuverability in proximity to an object which is to be repaired. The wheels 102 enable the body 101 to move with precision and stability, allowing it to be positioned accurately near the object that requires repair. The motorized functionality ensures that the movement is controlled remotely or automatically, facilitating efficient access to various parts of the object, thereby enhancing the repair process.

[0025] The motorized wheel comprises a disc or a wheel coupled with a motor via a shaft wherein upon receiving the command from the microcontroller by the motor, the motor starts to rotate in clockwise or anti-clockwise direction in order to provide movement to the wheel via the shaft. The wheel thus provides a maximum level of assistance to the user and also allow the user to maintain a steady speed while moving the body 101 in proximity to the object to be repaired.

[0026] The microcontroller actuates an artificial intelligence-based imaging unit 103 is installed on the body 101 to captures and processes multiple images of the area in proximity to the body 101 in order to detect the damaged portions on the leather surface of the object that requires repair. The artificial intelligence-based imaging unit 103 comprises of a camera lens and a processor, wherein the 360 degree rotatable camera captures multiple images in vicinity of the body 101 and then the processor carries out a sequence of steps including pre-processing, feature extraction and segmentation. In pre-processing, the unwanted data like noise, background is removed out and the image is converted into a format recommended for feature extraction. The features like pixel intensities of the foreground image are extracted and are sent for classification to detect the damaged portions on leather surface.

[0027] Upon detecting the damaged portions on leather surface, the microcontroller actuates a robotic arm 105 installed on the body 101 to acquire grip on electronically controlled nozzles 106 configured with the second section for positioning the nozzles 106 accurately onto the damaged patches of the object. Once in place, the nozzles 106 dispense an appropriate amount of glue from the chamber 104 onto the patches to ensure precise application of adhesive to the damaged areas, aiding in the effective repair of the leather surface by delivering the correct amount of glue directly where it is needed.

[0028] The robotic arm 105 comprises of a robotic link 111 and a clamp attached to the link 111. The robotic link 111 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 111 to complete a specific motion of the arm. Upon actuation of the robotic arm 105 by the microcontroller, the motor drives the movement of the clamp to position the nozzles 106 accurately onto the damaged patches of the object.

[0029] The electronic nozzle works by utilizing electrical energy to automize the flow solution in a controlled flow pattern by converting the pressure energy of a fluid into kinetic energy, which increases the fluid's velocity to dispense the glue. Upon actuation of nozzle by the microcontroller, the electric motor or the pump pressurizes the incoming glue, increasing its pressure significantly. High pressure enables the solution to be sprayed out with a high force over the patches.

[0030] Upon dispensing the glue on the patches, the microcontroller actuates a flap 107 installed on the body 101 using an extendable rod 108, to position the flap 107 precisely onto the dispensed glue. The action ensures that the glue is evenly spread or pressed onto the damaged leather patches, aiding in the bonding process and contributing to a smooth and secure repair. The extendable rod 108 is linked to a pneumatic unit, including an air compressor, air cylinders, air valves and piston which works in collaboration to aid in extension and retraction of the flap 107.

[0031] The pneumatic unit is operated by the microcontroller, such that the microcontroller actuates valve to allow passage of compressed air from the compressor within the cylinder, the compressed air further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the flap 107 and due to applied pressure the flap 107 extends and similarly, the microcontroller retracts the telescopically operated flap 107 by closing the valve resulting in retraction of the piston. Thus, the microcontroller regulates the extension/retraction of the piston in order to extend/retract for positioning the flap 107 onto the dispensed glue.

[0032] The microcontroller actuates a motorized ball and socket joint 109 integrated between the rod 108 and flap 107 in order to provide spreading movement to the dispensed glue for the even application of glue over the damaged patches, ensuring a uniform layer is applied to facilitate effective adhesion and repair of the leather surface.

[0033] The controlled movement enabled by the ball and socket joint 109 helps in achieving a smooth and consistent spread of glue across the patches. The ball and socket joint 109 is a coupling consisting of a ball joint securely locked within a socket joint 109, where the ball joint is able to move in a 360-dgree rotation within the socket thus, providing the required rotational motion to the flap 107. The ball and socket joint 109 is powered by a DC (direct current) motor that is actuated by the microcontroller thus providing multidirectional movement to the flap 107 for evenly applying the glue over the patches.

[0034] Upon applying the glue over the patches, the microcontroller actuates a robotic clipper 110 configured on the body 101 for gripping a suitable leather sheet from the chamber 104 and position it over a slot provided on the body 101. A robotic clipper 110 comprises of a robotic arm 105 equipped with a specialized clipping tool. The arm, powered by motors and actuators, moves with high precision to the designated spots, where the clipping tool, often driven by pneumatic or electric mechanisms, executes the clipping action to grip and position the suitable leather over the slot provided on the body 101.

[0035] An ultrasonic sensor embedded in the clipper 110 determines the dimensions of the leather sheet, ensuring that the sheet is of appropriate size and correctly aligned for the repair process. The precise measurement and placement help in effectively covering the damaged patches on the leather surface. The ultrasonic sensor works by emitting ultrasonic waves and then measuring the time taken by these waves to bounce back after hitting the surface of the leather sheet. The ultrasonic sensor includes two main parts viz. transmitter, and a receiver for leather sheet.

[0036] The transmitter sends a short ultrasonic pulse towards the surface of leather sheet which propagates through the air at the speed of sound and reflects back as an echo to the transmitter as the pulse hits the leather sheet. The transmitter then detects the reflected eco from the surface ….and calculations is performed by the sensor based on the time interval between the sending signal and receiving echo to determine the dimension of the leather sheet. The determined data is sent to the microcontroller in a signal form, based on which the microcontroller further process the signal.

[0037] In case the dimensions of the leather sheet mismatch the dimensions of the damaged patch, the microcontroller actuates a robotic link 111 installed on the body 101 to position the patch in proximity to the excess portions of the sheet in order to allow for the accurate alignment and trimming of the leather sheet to ensure it precisely fits the damaged area, ensuring a seamless repair of the leather surface. The robotic link 111 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 111 to complete a specific motion of the arm. Upon actuation of the robotic arm 105 by the microcontroller, the motor drives the movement of the clamp to position the patch in proximity to excess portions of the sheet.

[0038] Upon positioning the patch in proximity to excess portions of the sheet, the microcontroller actuates a motorized cutter 112 arranged on the link 111 to target the excess portions of the sheet. The cutter 112 is designed to trim the sheet precisely, cutting away the excess material to obtain a sheet of appropriate size and shape. The motorized feature allows for controlled and accurate cutting, ensuring that the sheet is tailored to the desired dimensions without manual intervention. The motorized cutter 112 assembled with a body 101 arranged on one end of the frame is actuated by the microcontroller for cutting the sheet.

[0039] The cutter 112 consists of motor connected to a set of blades for cutting the sheet. The motor is the key component that converts electrical energy into mechanical energy to provide movement to the blade. Upon actuation of the cutter 112 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 length the sheet to obtain an appropriate sheet.

[0040] A tactile sensor embedded on the cutter 112 monitors the hardness of the sheet. Based on the sensor's feedback, the microcontroller adjusts the speed of the cutter 112 to ensure optimal cutting performance and precision. The regulation helps in achieving a clean cut, regardless of the sheet's hardness, and ensures the sheet fits perfectly during the repair process. The tactile sensor detects the hardness of the sheet by measuring the force of contact between the sensor and the surface of sheet. The sensor is typically a small, flat component that is placed against surface of the sheet and then pressed down. As the force of contact increases, the sensor measures the amount of pressure being applied and sends a
signal to the microcontroller. The microcontroller then interprets the signal
and determines the hardness of sheet before cutting the sheet.

[0041] After cutting the sheet to the appropriate size, the robotic arm 105 is actuated to position the cut sheet onto the area where the glue has been applied. The microcontroller then directs the rod 108 to position the flap 107 onto the sheet, applying the necessary pressure to ensure that the sheet adheres properly to the patch. The process ensures a secure and even application of the sheet over the damaged patch, completing the repair.

[0042] Upon pasting the sheet over the patch, a color sensor embedded in the body 101 of the device determine the color of the leather surface. The sensor analyzes the color of the leather to ensure that the repair materials, such as glue and replacement sheets, match the original color of the leather in order to achieve a seamless repair that blends well with the existing leather, maintaining the aesthetic integrity of the item.

[0043] The color sensor operates by detecting and analyzing the wavelength of light reflected or emitted by the leather surface deposited on the spillway of the dam to determine the color of the leather surface. The sensor typically uses phototransistors that are sensitive to different wavelength of light. When light strikes the debris, the sensor measures the intensity of reflected light across specific color bands. The microcontroller further processes the signal to determine the color of the leather surface.

[0044] Upon determining the color of the leather surface, the microcontroller actuates multiple electronically controlled valves installed on the body 101 and configured with a multi-sectioned container that stores multiple liquid paints of varying colors. The microcontroller directs the robotic arm 105 to grip a suitable valve and position it onto the pasted sheet. The valve spray the selected paint onto the sheet, thereby renewing the object’s surface. The process ensures a precise color match and effective repair, ultimately maintaining the leather surface of the object. The electronically controlled valve is used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of the paint onto the sheet.

[0045] The chamber 104 is configured with a counter proximity sensor for counting the number of leather sheets. The counter proximity sensor detects the presence or absence of objects within a defined range using electromagnetic fields, typically infrared or radio waves. When an object enters the sensor’s range, it alters the electromagnetic field, causing a change in the sensor's output signal. This signal change is detected by the sensor's circuitry, which then processes it to determine the object's presence. The sensor often includes a counter to track the number of the leather sheets.

[0046] When the count of the leather sheets drops below a predetermined threshold, the microcontroller activates a speaker installed on the body 101. The speaker then produces an audio signal to alert the user that the first section needs to be refilled with additional leather sheets. The speaker 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 refill the leather sheets.

[0047] A level sensor embedded in each section of the container monitor the material levels. The sensor continuously measures the amount of material in its respective section. When the material level drops below a predefined threshold, the sensor sends this information to a microcontroller. The microcontroller then processes the data and directs the speaker to alert the user to refill the section in order to maintain the proper operation of the container and prevent interruptions caused by low material levels. The level sensor used herein is a preferably an ultrasonic level sensor.

[0048] The ultrasonic level sensor works by emitting ultrasonic waves and then measuring the time taken by these waves to bounce back after hitting the surface of the material level. The ultrasonic sensor includes two main parts viz. transmitter, propagator, reflector and a receiver for measuring the level of material level in the container. The transmitter sends a short ultrasonic pulse towards the surface of material level which propagates through the air at the speed of sound and reflects back as an echo to the transmitter as the pulse hits the key. The transmitter then detects the reflected eco from the surface of the material level and calculations is performed by the sensor based on the time interval between the sending signal and receiving echo to determine the level of material levels in the container.

[0049] 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.

[0050] The present invention works best in the following manner, comprises of the body 101 positioned on the ground and maneuvered near the object needing repair using motorized wheels 102. The artificial intelligence-based imaging unit 103 mounted on the device captures and processes images of the surrounding area to detect any damaged portions on the leather surface. Upon detecting damage, the device's microcontroller activates the robotic arm 105 that grips the electronically controlled nozzle connected to the chamber 104 storing glue. The nozzle is positioned over the damaged patch, and glue is dispensed onto the area. The flap 107 is then positioned over the dispensed glue. The motorized ball-and- socket joint 109 provides the spreading movement, ensuring the glue is evenly applied over the patch. The robotic clipper 110 grips the leather sheet from the chamber 104 and positions it over the slot on the device. The ultrasonic sensor embedded in the clipper 110 measures the dimensions of the sheet. If the sheet’s dimensions do not match the patch size, the microcontroller activates the robotic link 111 that positions the sheet near its excess portions. The motorized cutter 112 then trims the sheet to the correct size. The robotic arm 105 then places the cut sheet onto the glued patch, and the flap 107 is used to apply pressure, securing the sheet in place. To match the repaired area with the original leather surface, the color sensor embedded in the device determines the surface color. The device then selects the appropriate paint from the multi-sectioned container storing various liquid colors. The robotic arm 105 positions the valve over the patched area to spray the matching paint, effectively renewing the leather surface.
