Description

Technical Field

[0001] This invention belongs to the field of tire processing technology, specifically relating to a device for brushing tire beads on all-steel tires and its usage method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In the production of all-steel tires, the forming process is the core link that determines the overall performance and service life of the tire. The bead, as a key component connecting the tire to the rim, directly affects the airtightness, impact resistance, and high-speed stability of the tire after assembly due to the quality of its adhesion to the tire carcass ply and the triangular rubber. Defects in bead coating can easily lead to gaps at the bonding interface between the bead and the carcass. Under long-term load, thermal cycling, and frictional impact, this can easily cause delamination, bulges, or even tire blowouts. Therefore, quality control of the bead coating process is crucial. With the increasing automation in the all-steel tire industry, specialized automated bead coating equipment has gradually emerged to address the problems of high labor intensity, low efficiency, and poor quality consistency associated with traditional manual bead coating, replacing some manual operations. While these existing automated devices have reduced worker labor intensity and improved basic production efficiency to some extent, certain problems still exist.

[0004] Firstly, existing automated tire bead brushing equipment generally adopts a fixed bead and moving brush operation mode: the tire bead is fixed to the worktable by simple double-sided clamping blocks, and the clamping force needs to be manually adjusted according to the tire bead specifications. If the clamping force is too loose, the tire bead is prone to slight displacement during brushing; if the clamping force is too tight, it may cause deformation of the tire bead edge or surface damage, affecting the subsequent assembly accuracy. At the same time, the fixing structure of some equipment has poor adaptability, requiring frequent disassembly and replacement of positioning components for all-steel tire beads of different diameters and widths.

[0005] Secondly, the coating uniformity is insufficient, resulting in poor quality stability. Existing equipment requires a robotic arm to drive the brush in a compound motion along the circumference and both end faces of the tire bead to complete the coating. During this process, the contact pressure between the brush and the tire bead surface, as well as the moving speed, are easily affected by the transmission accuracy of the robotic arm and the roundness error of the tire bead surface. For example, a local protrusion on the circumference of the tire bead may cause an instantaneous increase in brush pressure, resulting in an excessively thick coating; while a slight deviation in the robotic arm trajectory may cause missed areas in the critical transition zone where the tire bead and the triangular adhesive bond, ultimately leading to differences in the coating thickness of tire beads from the same batch. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a device and method for brushing tire bead on all-steel tires, which is adaptable to tires of different sizes and has strong applicability; it also ensures uniform brushing and improves work efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A device for brushing tire bead of an all-steel tire includes an oil tank, which is connected to a brushing device on a robotic arm via an oil supply pipe. A device platform is provided at one end of the robotic arm, and a tire bead support is provided at the upper end of the device platform. A drive motor is installed inside the tire bead support, and the output end of the drive motor is connected to a rotating gear. A rotating plate is provided at the end of the rotating gear. A plurality of protrusions are spaced apart on the tire bead support, and the protrusions engage with the rotating gear. The rotating plate is connected to the tire bead support. The upper end of the rotating plate is provided with a retaining ring device, which includes a retaining ring claw mounting base. The upper end of the retaining ring claw mounting base is provided with a retaining ring claw. The retaining ring claw includes a mounting block, a moving block, and a driving structure. The mounting block is located at the upper end of the retaining ring claw mounting base and is detachably connected to the retaining ring claw mounting base. The upper end of the mounting block is provided with a moving block. One side of the moving block is fixedly connected to a connecting rod, and the connecting rod is connected to the driving structure.

[0008] As a further technical solution, one end of the oil delivery pipe is detachably connected to the oil drum, and the other end of the oil delivery pipe is detachably connected to the oil brushing device; a flow control valve is installed on the oil delivery pipe.

[0009] As a further technical solution, the oiling device is mounted on the robotic arm, and the oiling device is detachably connected to the robotic arm.

[0010] As a further technical solution, the brushing device is a clamping gasoline brush, which clamps the triangular rubber position of the tire bead to brush the tire during brushing.

[0011] As a further technical solution, the device platform is movably connected to the tire bead support, and the device platform is used to support the tire bead support; the rotating plate and the tire bead support are fixedly connected.

[0012] As a further technical solution, the drive motor is installed inside the tire bead support. The drive motor drives the rotating gear to rotate. The rotating gear is movably connected to the tire bead support. The rotating gear and the protrusion cooperate to drive the tire bead support to rotate, thereby driving the rotating plate to rotate.

[0013] As a further technical solution, the buckle device is arranged in several intervals around the center position of the rotating plate, and the lower end of the buckle mounting base is fixedly connected to the rotating plate; the upper end of the buckle mounting base is provided with several first screw holes at intervals.

[0014] As a further technical solution, the upper end of the mounting block is provided with a plurality of second screw holes at intervals, the second screw holes penetrate the mounting block, and mounting bolts are provided in the second screw holes. The mounting bolts are screwed into the second screw holes and the first screw holes in sequence to connect the mounting block and the buckle mounting seat; a movable block is provided at the upper end of the mounting block, and the movable block is movably connected to the mounting block.

[0015] As a further technical solution, a control device is also included, which includes a controller and an operation panel. The operation panel is provided with a start rotary switch, and the controller is electrically connected to the start rotary switch, the drive motor, the drive structure, and the flow control valve.

[0016] The method of using a brush bead device for all-steel tires includes the following steps: Place the tire bead to be brushed steadily in the center area of ​​the tire bead support, ensuring that the lower surface of the tire bead fits tightly against the tire bead support without tilting or shifting; press the start rotary switch on the operation panel, the command is transmitted to the controller, the controller synchronously drives the drive structure of the bead-fastening device, so that the moving block moves towards the tire bead until the moving block firmly clamps the steel ring position of the tire bead, thus completing the secure fixing of the tire bead. The controller drives the robotic arm to move the oil brushing device, so that the gasoline brush is precisely aligned with the triangular rubber position of the tire bead and clamped and fixed; the controller starts the drive motor, the drive motor drives the rotating gear to rotate, the rotating gear further drives the tire bead support to rotate, which in turn drives the rotating plate to rotate, which in turn drives the bead fastening device and the tire bead to rotate at a constant speed. At the same time, the controller opens the flow control valve on the oil delivery pipe, and the gasoline in the oil drum is delivered to the oil brushing device through the oil delivery pipe. The clamp-type gasoline brush evenly brushes both sides of the tire bead as the tire bead rotates until the tire bead rotates one full turn and the brushing operation is completed. After the paint is applied, the controller receives a signal that the tire bead has rotated one revolution, automatically stops the drive motor, and closes the flow control valve to cut off the gasoline supply. The paint brushing device releases its grip on the triangular rubber, and the robotic arm drives the paint brushing device back to its initial position. The drive structure of the bead fastening device moves the moving block in the opposite direction, releasing the fixation on the tire bead. The painted tire bead can then be removed from the tire bead support.

[0017] Compared with the prior art, the advantages and positive effects of this invention are: The bead clamp mounting base and mounting block of this invention are detachably connected via a first screw hole, a second screw hole, and mounting bolts. When the bead size is large, only the mounting bolts need to be removed to adjust the fixed position of the mounting block on the bead clamp mounting base, without replacing the entire positioning component. The movable block at the upper end of the mounting block is fixedly connected to the drive structure. When the bead size changes slightly, the controller drives the drive structure to move the movable block along the mounting block, quickly adapting to the bead clamping requirements. This avoids the cumbersome operation of frequently replacing positioning components in existing equipment and eliminates the need for repeated manual adjustment of the clamping force, ensuring that all-steel tire beads of different specifications can be stably fixed, thus improving the applicability of the device.

[0018] The drive motor, rotating gear, and protrusion within the tire bead support of this invention engage. The drive motor rotates the rotating gear, which in turn rotates the tire bead support. The tire bead support then rotates the rotating plate, which in turn rotates the tire bead fixed by the bead-fastening device at a uniform speed, preventing missed areas caused by deviations in the robotic arm's trajectory. Simultaneously, the robotic arm precisely aligns and clamps the triangular rubber position of the tire bead with the clamping gasoline brush, ensuring a fixed contact position between the brush and the tire bead, unaffected by errors in the roundness of the tire bead surface. Furthermore, the flow control valve on the fuel line stably controls the gasoline delivery, preventing coating thickness variations caused by fluctuations in fuel volume. During the brushing process, the brush maintains a stable contact with the tire bead surface, and the brushing trajectory naturally covers the surface as the tire bead rotates, ensuring consistent brushing quality for each tire bead.

Detailed Implementation

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] Existing automated tire bead brushing equipment generally adopts a fixed bead and moving brush operation mode: the tire bead is fixed to the worktable by simple double-sided clamping blocks, and the clamping force needs to be adjusted manually according to the tire bead specifications. If the clamping force is too loose, the tire bead is prone to slight displacement during brushing; if the clamping force is too tight, it may cause deformation of the tire bead edge or surface damage, affecting the subsequent assembly accuracy. At the same time, the fixing structure of some equipment has poor adaptability, and for all-steel tire beads of different diameters and widths, the positioning components need to be frequently disassembled and replaced.

[0023] Secondly, the coating uniformity is insufficient, resulting in poor quality stability. Existing equipment requires a robotic arm to drive the brush in a compound motion along the circumference and both end faces of the tire bead to complete the coating. During this process, the contact pressure between the brush and the tire bead surface, as well as the moving speed, are easily affected by the transmission accuracy of the robotic arm and the roundness error of the tire bead surface. For example, a local protrusion on the circumference of the tire bead may cause an instantaneous increase in brush pressure, resulting in an excessively thick coating; while a slight deviation in the robotic arm trajectory may cause missed areas in the critical transition zone where the tire bead and the triangular adhesive bond, ultimately leading to differences in the coating thickness of tire beads from the same batch.

[0024] Example 1: The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a device for brushing the bead of an all-steel tire, such as... Figure 1 As shown, it includes an oil drum 1, which is connected to an oil brushing device 4 on a robotic arm 3 via an oil supply pipe 2. A device platform 5 is set at one end of the robotic arm 3, and a tire bead support 9 is set at the upper end of the device platform 5. A drive motor 6 is installed inside the tire bead support 9, and the output end of the drive motor 6 is connected to a rotating gear 7. A rotating plate 10 is set at the end of the rotating gear 7. Several protrusions 11 are spaced apart on the tire bead support 9, and the protrusions 11 are engaged with the rotating gear 7. The rotating plate 10 is connected to the tire bead support 9. A retaining ring device 8 is provided at the upper end of the rotating plate 10. The retaining ring device 8 includes a retaining ring claw mounting base 81. A retaining ring claw is provided at the upper end of the retaining ring claw mounting base 81. The retaining ring claw includes a mounting block 83, a moving block 87, and a driving structure 86. The mounting block 83 is provided at the upper end of the retaining ring claw mounting base 81 and is detachably connected to the retaining ring claw mounting base 81. The moving block 87 is provided at the upper end of the mounting block 83. One side of the moving block 87 is fixedly connected to the connecting rod 88. The connecting rod 88 is connected to the driving structure 86.

[0025] Specifically, the drive structure 86 is a hydraulic cylinder equipped with corresponding hydraulic lines to provide hydraulic power. The output end of the hydraulic cylinder is connected to the connecting rod 88; one end of the connecting rod is connected to the moving block 87. Specifically, the bead clamp mounting base 81 and the mounting block 83 are detachably connected via the first screw hole 82, the second screw hole 84, and the mounting bolt 85. When the tire bead size is large, only the mounting bolt 85 needs to be removed to adjust the fixed position of the mounting block 83 on the bead clamp mounting base 81, without replacing the entire positioning component. The moving block 87 at the upper end of the mounting block 83 is fixedly connected to the drive structure 86. When the tire bead size changes slightly, the controller drives the drive structure 86, which in turn moves the moving block 87 along the mounting block 83, quickly adapting to the tire bead clamping requirements. This avoids the cumbersome operation of frequently replacing positioning components in existing equipment and eliminates the need for repeated manual adjustments of the clamping force, ensuring that all-steel tire beads of different specifications can be stably fixed, thus improving the applicability of the device.

[0026] The drive motor 6 inside the tire bead support 9, through the cooperation of the rotating gear 7 and the protrusion 11, ultimately drives the rotating plate 10 to rotate, which in turn drives the tire bead fixed by the bead-fastening device 8 to rotate at a uniform speed, avoiding missed brushing caused by the trajectory deviation of the robotic arm 3. At the same time, the robotic arm 3 drives the clamping gasoline brush to precisely align and clamp the triangular rubber position of the tire bead, so that the brush and tire bead contact position is always fixed and not affected by the roundness error of the tire bead surface. In addition, the flow control valve on the fuel line 2 can stably control the gasoline delivery volume, preventing coating thickness differences caused by fuel volume fluctuations. During the brushing process, the brush and tire bead surface always maintain a stable contact state, and the brushing trajectory naturally covers the surface as the tire bead rotates, ensuring that the brushing quality of each tire bead is consistent.

[0027] One end of the oil delivery pipe 2 is detachably connected to the oil drum 1, and the other end of the oil delivery pipe 2 is detachably connected to the oil brushing device 4; a flow control valve is installed on the oil delivery pipe 2.

[0028] Specifically, when the gasoline in oil drum 1 is exhausted and needs to be replaced, the operator does not need to use special tools. He only needs to manually unplug the quick connector connecting one end of the oil supply pipe 2 to the oil outlet of oil drum 1 to remove the empty oil drum 1 and replace it with a full oil drum 1. Then, the quick connector is reconnected and fixed. If the oil brushing device 4 is worn and needs to be repaired or replaced, the oil supply pipe 2 and the oil brushing device 4 can be quickly separated by unplugging the quick connector connecting the other end of the oil supply pipe 2 to the oil inlet of the oil brushing device 4, thus avoiding the extended downtime caused by the overall disassembly.

[0029] Specifically, the brushing device 4 is an integrally molded duckbill contact device, which is an existing structure. The brushing device 4 is in contact with the tire bead and clamped. The clamping force is less than the rotational friction force, so it will not affect the rotation of the tire bead.

[0030] Meanwhile, the flow control valve installed in the middle of the oil pipeline 2 is electrically connected to the controller of the control device. When applying paint to tire bead of different sizes, the operator can send instructions to the controller through the control panel, and the controller can adjust the opening and closing degree of the flow control valve. For example, when applying paint to a narrower tire bead, the valve opening and closing degree can be reduced to reduce the amount of gasoline delivered and avoid gasoline waste; when applying paint to a wider tire bead, the valve opening and closing degree can be appropriately increased to ensure full coverage of the application area, without the need for manual adjustment of the valve.

[0031] The paint brushing device 4 is mounted on the robotic arm 3 and is detachably connected to the robotic arm 3. The paint brushing device 4 is a clamping gasoline brush, which clamps the triangular rubber part of the tire bead to brush the tire during painting.

[0032] Specifically, during the brushing operation, the robotic arm 3 moves according to the trajectory preset by the controller, driving the clamping gasoline brush to precisely approach the triangular rubber position of the tire bead. After the clamping mechanism of the gasoline brush is aligned with the triangular rubber, the controller drives the clamping mechanism to close, clamping the triangular rubber to fix the brushing position. Then the tire bead begins to rotate, and the clamping gasoline brush, while maintaining the clamping state, brushes the key area where the tire bead and the triangular rubber meet, as well as both sides of the tire bead.

[0033] The device platform 5 is movably connected to the tire bead support 9, and the device platform 5 is used to support the tire bead support 9; the rotating plate 10 is fixedly connected to the tire bead support 9. The drive motor 6 is installed inside the tire bead support 9, and the drive motor 6 drives the rotating gear 7 to rotate. The rotating gear 7 is movably connected to the tire bead support 9. The rotating gear 7 and the protrusion 11 cooperate to drive the tire bead support 9 to rotate, which in turn drives the rotating plate 10 to rotate.

[0034] Specifically, the inner side of the tire bead support 9 has a pre-reserved mounting cavity that matches the size of the drive motor 6. The drive motor 6 is fully embedded in the mounting cavity, and the motor housing is fixed to the inner wall of the tire bead support 9 with bolts to prevent displacement during motor operation. The output shaft end of the drive motor 6 is fixed to the rotating gear 7 by a key connection, and the upper end face of the rotating gear 7 is connected to the center position of the lower surface of the rotating plate 10 by bolts.

[0035] When the controller sends a start command to the drive motor 6, the motor output shaft drives the rotating gear 7 to rotate, the rotating gear 7 drives the tire bead support 9 to rotate, and then drives the rotating plate 10 to rotate. The tire bead placed on the rotating plate 10 rotates at a constant speed with the rotating plate 10.

[0036] A plurality of retaining ring devices 8 are arranged at intervals around the center position of the rotating plate 10. The lower end of the retaining ring mounting base is fixedly connected to the rotating plate 10. A plurality of first screw holes 82 are arranged at intervals on the upper end of the retaining ring mounting base. A plurality of second screw holes 84 are arranged at intervals on the upper end of the mounting block 83. The second screw holes 84 penetrate the mounting block 83. Mounting bolts 85 are installed in the second screw holes 84. The mounting bolts 85 are screwed into the second screw holes 84 and the first screw holes 82 in sequence to connect the mounting block 83 and the retaining ring mounting base. A movable block 87 is provided on the upper end of the mounting block 83. The movable block 87 is movably connected to the mounting block 83.

[0037] Specifically, four bead-fastening devices 8 are evenly spaced around the center of the rotating plate 10, and the four bead-fastening devices 8 are distributed in a circle to ensure that the clamping force on the tire bead is evenly distributed.

[0038] When the size of the tire bead to be brushed changes significantly, that is, when changing from a small tire to a large tire or vice versa, the operator unscrews the mounting bolt 85 that passes through the second screw hole 84 and the first screw hole 82, moves the mounting block 83 along the length of the bead claw mounting seat 81, so that the position of the mounting block 83 matches the outer contour of the new size tire bead, and then screws the mounting bolt 85 back in to fix the mounting block 83.

[0039] If the change in tire bead size is small, that is, the size of the replacement tire is close, there is no need to remove the bolts: the controller drives the drive structure 86 in the bead-locking device 8, such as an electric push rod. The piston rod of the electric push rod is fixedly connected to the moving block 87. Under the push of the drive structure 86, the moving block 87 moves along the slide rail preset on the upper end face of the mounting block 83 until the inner clamping surface of the moving block 87 is in contact with the steel ring position of the tire bead, thus completing the quick adjustment.

[0040] It also includes a control device, which includes a controller and an operation panel. The operation panel is equipped with a start rotary switch. The controller is electrically connected to the start rotary switch, the drive motor 6, the drive structure 86, and the flow control valve.

[0041] Specifically, the control panel is installed on the side of the device platform 5, which is convenient for operators to stand and operate. The control panel is equipped with a start rotary switch with an indicator light. The controller is installed in the electrical control box inside the device platform 5. It is electrically connected to the start rotary switch, drive motor 6, drive structure 86 of buckle device 8 and flow control valve through wires to form a centralized control system.

[0042] When the operator presses the start rotation switch, the switch indicator light illuminates, and a start signal is sent to the controller. The controller first sends a command to the drive structure 86 of the bead-fastening device 8 to drive the moving block 87 to clamp the tire bead; then it sends a command to the robotic arm 3 to drive the oil brushing device 4 to clamp the triangular rubber; next, it sends a command to the drive motor 6 to start the motor and drive the tire bead to rotate; finally, it sends a command to the flow control valve to open the valve and deliver gasoline.

[0043] Throughout the process, the controller receives feedback signals from each component in real time. When the tire bead completes one rotation, the controller sequentially sends a stop command to the drive motor 6, a close command to the flow control valve, a release command to the oil brushing device 4, and a release command to the bead fastening device 8, thereby achieving linkage control of each component without the need for manual step-by-step operation.

[0044] Example 2: The method of using a brush bead device for all-steel tires includes the following steps: Place the tire bead to be brushed steadily in the center area of ​​the tire bead support 9, ensuring that the lower surface of the tire bead fits tightly against the tire bead support 9 without tilting or shifting; press the start rotary switch on the operation panel, the command is transmitted to the controller, the controller synchronously drives the drive structure 86 of the bead-fastening device 8, so that the moving block 87 moves towards the tire bead until the moving block 87 firmly clamps the steel ring position of the tire bead, thus completing the secure fixing of the tire bead; The controller drives the robotic arm 3 to move the oil brushing device 4, so that the gasoline brush is accurately aligned with the triangular rubber position of the tire bead and clamped and fixed; the controller starts the drive motor 6, the drive motor 6 drives the rotating gear 7 to rotate, the rotating gear 7 further drives the tire bead support 9 to rotate, which in turn drives the rotating plate 10 to rotate, which in turn drives the bead fastening device 8 and the tire bead to rotate at a uniform speed. At the same time, the controller controls the flow control valve on the oil pipe 2 to open, and the gasoline in the oil drum 1 is transported to the oil brushing device 4 through the oil pipe 2. The clamp-type gasoline brush evenly brushes both sides of the tire bead during the tire bead rotation until the tire bead rotates one full turn and the brushing operation is completed. After the coating is completed, the controller receives a signal that the tire bead has rotated one revolution, automatically stops the drive motor 6, and closes the flow control valve to cut off the gasoline supply. The brushing device 4 releases its grip on the triangular rubber, and the robotic arm 3 drives the brushing device 4 back to its initial position. The drive structure 86 of the bead-fastening device 8 drives the moving block 87 to move in the opposite direction, releasing the fixation on the tire bead. The coated tire bead can then be removed from the tire bead support 9.

[0045] Adjust the bead-fastening device 8 according to the actual size of the all-steel tire bead to be brushed, and send a command to the controller through the operation panel. The controller drives the drive structure 86 in the bead-fastening device 8 to move, causing the moving block 87 to move along the movable track of the mounting block 83 until the clamping surface of the moving block 87 matches the position of the steel bead of the tire bead to be brushed.

[0046] Alternatively, remove the mounting bolt 85 from the second screw hole 84 on the mounting block 83 to separate the mounting block 83 from the bead clamp mounting seat 81; according to the requirements of the bead size change, move the mounting block 83 to the position of the matching first screw hole 82 on the bead clamp mounting seat 81 to ensure that the moving block 87 at the upper end of the mounting block 83 can cover the bead clamping range; screw the mounting bolt 85 into the second screw hole 84 of the mounting block 83 and the first screw hole 82 of the bead clamp mounting seat 81 in sequence to tighten and fix the mounting block 83; then fine-tune the position of the moving block 87 through the drive structure 86 to complete the precise adaptation of the bead fixing size; After the brushing operation is completed, turn off the main power supply of the device and clean the residual gasoline and impurities on the brushing device 4; check the connection status of the moving block 87 and the mounting block 83. If different sizes of tire bead need to be replaced later, the size can be adjusted by the buckle device 8 to ensure the stability of the equipment when it is used next time.

[0047] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.

9. A tire bead brush device for all-steel tires as described in claim 1, characterized in that, It also includes a control device, which includes a controller and an operation panel. The operation panel is equipped with a start rotary switch, and the controller is electrically connected to the start rotary switch, the drive motor, the drive structure, and the flow control valve.

10. The method of using the all-steel tire brush bead device as described in any one of claims 1-9, characterized in that, Includes the following steps: Place the tire bead to be brushed steadily in the center area of ​​the tire bead support, ensuring that the lower surface of the tire bead fits tightly against the tire bead support without tilting or shifting; press the start rotary switch on the operation panel, the command is transmitted to the controller, the controller synchronously drives the drive structure of the bead-fastening device, so that the moving block moves towards the tire bead until the moving block firmly clamps the steel ring position of the tire bead, thus completing the secure fixing of the tire bead. The controller drives the robotic arm to move the oil brushing device, so that the gasoline brush is precisely aligned with the triangular rubber position of the tire bead and clamped and fixed; the controller starts the drive motor, the drive motor drives the rotating gear to rotate, the rotating gear further drives the tire bead support to rotate, which in turn drives the rotating plate to rotate, which in turn drives the bead fastening device and the tire bead to rotate at a constant speed. At the same time, the controller opens the flow control valve on the oil delivery pipe, and the gasoline in the oil drum is delivered to the oil brushing device through the oil delivery pipe. The clamp-type gasoline brush evenly brushes both sides of the tire bead as the tire bead rotates until the tire bead rotates one full turn and the brushing operation is completed. After the paint is applied, the controller receives a signal that the tire bead has rotated one revolution, automatically stops the drive motor, and closes the flow control valve to cut off the gasoline supply. The paint brushing device releases its grip on the triangular rubber, and the robotic arm drives the paint brushing device back to its initial position. The drive structure of the bead fastening device moves the moving block in the opposite direction, releasing the fixation on the tire bead. The painted tire bead can then be removed from the tire bead support.
