[0028] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0029] See attached document Figure 1 This embodiment of an automotive parts painting production line includes a transmission component 1, which is composed of parts such as a conveyor belt. In use, the automotive parts to be painted are placed on the conveyor belt, and the conveyor belt is used to transport the automotive parts.

[0030] See attached document Figure 1 , Figure 3 and Figure 4The transmission component 1 is externally mounted with a frame 2. A height adjustment component 3 is mounted on the frame 2. The height adjustment component 3 includes a first double-rotation screw 301 rotatably mounted on the frame 2. A first motor 302 is mounted on the frame 2, and the output shaft of the first motor 302 is connected to the first double-rotation screw 301. When in use, the first motor 302 is turned on, and its output shaft drives the first double-rotation screw 301 to rotate. A first guide rod 303 is mounted on both sides of the first double-rotation screw 301 on the frame 2. A first movable seat 304 is threadedly connected to both sides of the first double-rotation screw 301, and the first guide rod 303 passes through both first movable seats 304, thus achieving... The first movable seat 304 on both sides is limited, so that the first movable seat 304 on both sides can move towards each other or away from each other during the rotation of the first double-rotation screw 301. A lifting pad 307 is provided below the first double-rotation screw 301. Two first connecting seats 305 are fixedly installed on the top of the lifting pad 307. A first connecting rod 306 is movably installed between the first movable seat 304 and the first connecting seat 305 on the same side. Under the connection of the first connecting rod 306, the first movable seat 304 on both sides moves towards each other or away from each other, so as to realize the adjustment of the height of the lifting pad 307, and thus adjust the distance between the nozzle 9 and the automotive parts.

[0031] See attached document Figure 1 , Figure 3 and Figure 4 A connecting pad 4 is located below the height adjustment component 3. The height of the connecting pad 4 is adjusted along with the lifting pad 307. A column 5 is fixedly installed at the middle of the top of the connecting pad 4, and the connecting pad 4 is connected to the height adjustment component 3 through the column 5. That is, the column 5 and the lifting pad 307 are rotatably connected. The height adjustment component 3 is equipped with a drive component 6 that drives the column 5 to rotate. The drive component 6 includes a large gear 601 fixedly installed on the top of the column 5. A second motor 602 is installed on the lifting pad 307. The output shaft of the second motor 602 is connected to a small gear 603 that meshes with the large gear 601. When in use, the second motor 602 is turned on, and the output shaft of the second motor 602 drives the small gear 603 to rotate, thereby realizing the rotation of the large gear 601 and the column 5, and in turn, the rotation of the connecting pad 4 and the nozzle 9. The spray direction can be adjusted according to the spraying requirements, improving spraying efficiency and coverage area.

[0032] See attached document Figure 1 , Figure 5 and Figure 6A flip-up pad 7 is hinged to one side of the connecting pad 4. An angle adjustment assembly 8 is provided between the connecting pad 4 and the flip-up pad 7. The angle adjustment assembly 8 includes two upright plates 801 fixedly installed at the bottom of the connecting pad 4. A one-way screw 802 is rotatably installed between the two upright plates 801. A No. 3 motor 803 is installed on one of the upright plates 801, and the output shaft of the No. 3 motor 803 is connected to the one-way screw 802. When in use, the No. 3 motor 803 is turned on, and the output shaft of the No. 3 motor 803 drives the one-way screw 802 to rotate. A No. 2 screw is threaded onto the one-way screw 802. The second movable seat 806 is positioned such that its top is in contact with the bottom of the connecting pad 4, thus limiting its movement and allowing it to move during the rotation of the one-way screw 802. A second connecting seat 804 is fixedly mounted on the flip pad 7, and a second connecting rod 805 is movably mounted between the second movable seat 806 and the second connecting seat 804. Under the connection of the second connecting rod 805, when the second movable seat 806 moves, the angle of the flip pad 7 also changes, thereby adjusting the angle of the nozzle 9.

[0033] See attached document Figure 1 , Figure 7 and Figure 8 Multiple nozzles 9 are provided below the flip pad 7. Specifically, the bottom of the flip pad 7 is fixedly installed with a number of mounting seats 10 equal to the number of nozzles 9. Both sides of the mounting seat 10 are provided with insertion holes 11. Limiting holes 12 are provided on the insertion holes 11, and the limiting holes 12 are perpendicular to the insertion holes 11. The mounting seat 10 is provided with a mating seat 13. Both sides of the mating seat 13 are fixedly installed with insertion rods 14 that are compatible with the insertion holes 11. The insertion rods 14 are provided with mounting holes. Springs 15 are fixedly installed in the mounting holes. Limiting blocks 16 that are compatible with the limiting holes 12 are fixedly installed on the outer end of the springs 15. When installing nozzle 9, first place nozzle 9 between mounting base 10 and mating base 13. Then press the limiting block 16 on mating base 13, causing the limiting block 16 to retract into the mounting hole. At this time, spring 15 is in a compressed state. Then, insert the insertion rod 14 on mating base 13 into the insertion hole 11 on mounting base 10. When the limiting block 16 just pops out from the limiting hole 12, the connection between mounting base 10 and mating base 13 is achieved, thus completing the installation of nozzle 9. The installation of nozzle 9 is achieved using a snap-fit ​​structure, which is simple to operate and easy to disassemble and replace.

[0034] See attached document Figure 1 and Figure 2In another embodiment, brackets 17 are fixedly installed on both sides of the frame 2, and a second double-rotating screw 18 is rotatably installed between the two brackets 17. A fourth motor 19 is installed on one of the brackets 17, and the output shaft of the fourth motor 19 is connected to the second double-rotating screw 18. When in use, the fourth motor 19 is turned on, and the output shaft of the fourth motor 19 drives the second double-rotating screw 18 to rotate. Movable plates 20 are threadedly connected to both sides of the second double-rotating screw 18, and a limit rod is fixedly installed between the two brackets 17. 21, and the limiting rod 21 passes through the two moving plates 20, thereby limiting the moving plates 20, so that the two moving plates 20 can move towards or away from each other during the rotation of the second double-rotation screw 18. Multiple correction rollers 22 are rotatably installed on the inner wall of the moving plate 20. The correction rollers 22 on both sides move synchronously with the two moving plates 20. By using the correction rollers 22 on both sides, the position of the automotive parts to be sprayed on the transmission assembly 1 can be corrected to ensure the spraying quality.

[0035] In operation, automotive parts are placed on the conveyor belt of the transmission assembly 1 and move forward to the spraying area as the conveyor belt moves. The height adjustment assembly 3, based on the size of the parts and the spraying requirements, drives the first moving seat 304 to move along the first guide rod 303 by rotating the first double-rotating screw 301. Then, the height of the lifting pad 307 and the nozzle 9 is adjusted by the first connecting rod 306 to ensure that the nozzle 9 maintains an appropriate distance from the parts. At the same time, the second motor 602 in the drive assembly 6 drives the pinion 603 to rotate. The pinion 603 meshes with the large gear 601 to drive the column 5 and the connecting pad 4 to rotate, realizing all-round spraying of the nozzle 9. The angle adjustment assembly 8 drives the unidirectional screw 802 to rotate by the third motor 803, causing the second moving seat 806 to move along the unidirectional screw 802. The second connecting rod 805 drives the flipping pad 7 and the nozzle 9 to rotate around the connecting pad 4 to adjust the spray angle of the nozzle 9. In addition, the correction roller 22 assembly is driven by the No. 4 motor 19 to rotate the No. 2 double-rotating screw 18, so that the moving plates 20 on both sides and the correction roller 22 move synchronously to correct the position of the parts on the conveyor belt and ensure the spraying accuracy.
