Description

Technical Field

[0001] This utility model relates to the field of automotive parts painting, specifically an automotive parts painting robot. Background Technology

[0002] In the automotive manufacturing industry, it is necessary to coat the surfaces of automotive parts to improve their appearance quality and corrosion resistance. Since manual painting is labor-intensive and the quality is inconsistent, coating of automotive parts is now mostly done by painting robots. A search reveals an automotive parts painting robot disclosed in application number CN202411000934.5, which describes a robot body with cantilever arms fixedly connected to both the front and rear sides of the robot body's bottom. A support plate is fixedly connected to the top of each cantilever arm, and a fixed frame is fixedly connected to the top of the support plate. The fixed frame contains a flipping mechanism for flipping the gripped automotive parts. The structural design involves a servo motor driving a drive gear to rotate. The drive gear meshes with two sets of racks, causing the racks to move in opposite directions. During this movement, the racks drive the driven gears that mesh with them to rotate, causing the driven gears to flip. This flipping of the driven gears causes the clamping assembly to rotate, thereby flipping the car parts clamped and fixed on the clamping assembly so that the back of the car parts can be painted. However, the above description has the following drawbacks in actual use: the painting effect of this painting robot is insufficient, it lacks flexibility, and it cannot be adjusted according to the length of some car parts. Therefore, it is necessary to design a more practical car parts painting robot. Utility Model Content

Please see Figure 3 Adjustment component 2 includes a reciprocating motor 21 installed on one side of the inner wall of the slide 11. The output shaft of the reciprocating motor 21 is fixedly connected to a threaded rod 22. The other end of the threaded rod 22 is rotatably connected to the other side of the inner wall of the slide 11 through a bearing 23. A slider 24 is threadedly connected to the surface of the threaded rod 22. A movable seat 25 is fixedly connected to the top of the slider 24. The two sides of the bottom of the movable seat 25 are slidably connected to the surfaces of two T-shaped slide rails 26. Limiting blocks 27 are provided at both ends of the two T-shaped slide rails 26. The bottom of the two limiting blocks 27 is fixedly connected to one side of the top of the base plate 1.

The threaded rod 22 drives the slider 24 to move reciprocally on the inner wall of the slide groove 11. The slider 24 drives the moving seat 25 to move on the surface of the two T-shaped slide rails 26. With the help of two limit blocks 27, the movement range of the moving seat 25 is limited, thereby facilitating the movement of the spraying structure on the mounting base 31. This allows for the adjustment of the reciprocating spraying position of long automotive parts, improving the flexibility of the spraying process.

[0017] Please see Figure 4 The spraying assembly 3 includes a mounting base 31 installed on the movable base 25. The top of the mounting base 31 has a first groove 32.

[0019] In practical use: the first motor 33 drives the first turntable 34 to rotate in the first annular groove 35. The first turntable 34 drives the first robotic arm 36, the second robotic arm 37 and the third robotic arm 38 to rotate, thereby changing the angle. The first robotic arm 36, the second robotic arm 37 and the third robotic arm 38 cooperate with each other to further adjust the spraying angle according to the shape and size of the automotive parts. The pump body 16 and the liquid extraction pipe 15 extract the liquid from the storage tank 12 and send it to the liquid supply connector 310 through the telescopic hose 17. Finally, the liquid is sprayed onto the surface of the automotive parts on the tray frame 112 through the nozzle 39 to complete the painting operation and improve the practicality of the painting robot.

In practical use: two sets of electric push rods 115 drive two sets of cross blocks 114 to move within the inner walls of two sets of cross grooves 113. The two sets of cross blocks 114, in conjunction with the connecting rod, drive two sets of support blocks 116 to move until the sides of the two sets of support blocks 116 support the inner wall of the circular automotive part, thus fixing it. The second motor 19 drives the second turntable 110 to rotate within the second annular groove 111. The second turntable 110, in conjunction with the plate frame 112, drives the fixed automotive part to rotate, thereby facilitating the adjustment of the spraying position during the spraying process and improving the spraying efficiency.

[0022] Please see Figure 3 The bottom of the movable seat 25 has T-shaped grooves 28 on both sides, and the inner walls of the two T-shaped grooves 28 are slidably connected to the surfaces of the two T-shaped slide rails 26.

[0026] Please see Figure 1 The reciprocating motor 21, the first motor 33, and the second motor 19 are all electrically connected to an external power supply via a control panel.

[0027] In practical use: The reciprocating motor 21, the first motor 33 and the second motor 19 are controlled by the control panel, which facilitates the painting robot to perform painting operations on automotive parts.

[0028] In use, after the automotive parts are fixed in place, the first motor 33 drives the first turntable 34 to rotate within the first annular groove 35. The first turntable 34 drives the first robotic arm 36, the second robotic arm 37, and the third robotic arm 38 to rotate, thereby changing the angle. The first robotic arm 36, the second robotic arm 37, and the third robotic arm 38 work together to further adjust the spraying angle according to the shape and size of the automotive parts. The pump body 16 and the liquid extraction pipe 15 draw liquid from the reservoir 12, which is then delivered through the telescopic hose 17 to the liquid supply connector 310. Finally, the liquid is discharged... The nozzle 39 sprays onto the surface of the automotive parts on the tray 112. During this process, the reciprocating motor 21, in conjunction with the bearing 23, drives the threaded rod 22 to rotate. The threaded rod 22 drives the slider 24 to move reciprocally along the inner wall of the slide groove 11. The slider 24 drives the moving seat 25 to move on the surfaces of the two T-shaped slide rails 26. The two limit blocks 27 limit the movement range of the moving seat 25, which facilitates the movement of the spraying structure on the mounting base 31. This allows for the adjustment of the reciprocating spraying position for long automotive parts, completing the painting operation and improving the practicality of the painting robot.
