[0004] Based on the above patent, hydraulic telescopic rods are arranged in the middle of the inner walls on both sides of the box body. A push plate is fixedly connected to one end of the hydraulic telescopic rod. A plurality of springs are arranged inside the push plate. One end of the spring is provided with a clamping rod. When clamping an automobile panel, the push plate is driven to move forward by the hydraulic telescopic rod, so that the clamping rod expands and contracts through the spring to complete the clamping work of the panel.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present invention: A surface painting device for automotive panel processing, comprising:

[0032] A spraying chamber 1 for placing parts, fixed frames 4 are fixedly connected to both the left and right ends of the inner wall of the spraying chamber 1, and the rear end of the spraying chamber 1 is connected to a heating wire 16 through a hot air drying group for heat drying the parts placed in the spraying chamber 1. The hot air chamber 3 fixedly connected to the outer wall of the rear end of the spraying chamber 1 penetrates through, and a plurality of circulating fans 25 are fixedly connected to the top end of the inner wall of the hot air chamber 3, and the outer wall of the heating wire 16 is fixedly connected to the bottom end of the inner wall of the hot air chamber 3.

[0033] Specifically: When the infusion water pump 8 is started, the paint in the stirring chamber 5 is transported to the spray head 14 through the infusion pipe 10 and evenly sprayed on the surface of the parts to be painted. At the same time, the circulating fan 25 in the hot air chamber 3 starts to operate, inhaling external air and heating it through the heating wire 16 to generate hot air. The hot air is then introduced into the spraying chamber 1 through the nozzle to dry the painted parts. In this way, not only is the uniform adhesion of the paint ensured, but also the spraying efficiency is improved through the rapid drying process, preventing the paint from sagging or having defects on the surface of the parts, and further improving the overall quality of the coating.

[0034] Refer to Figure 5 and Figure 6, as a fixed shell 2 for spraying paint, an infusion water pump 8 is fixedly connected to the rear side of the top of the spraying bin 1, and the output end of the infusion water pump 8 is connected to a spray head 14 through an infusion group for infusing paint into the spray head 14, and the opposite end of the inner wall of the fixed shell 2 is fixedly connected to a second motor 9, and the driving end of the second motor 9 is connected to a moving column 13 through a moving group for adjusting the spraying angle at the spray head 14, an infusion tube 10 fixedly connected to the output end of the infusion water pump 8, and the input end of the infusion water pump 8 is fixedly connected to the outer wall of the stirring bin 5 and penetrates, and a reciprocating screw rod 11 fixedly connected to the driving end of the second motor 9, and a slider 12 is sleeved on the outer wall of the reciprocating screw rod 11, and a connecting plate 15 is rotatably connected to the upper and lower sides of the opposite end of the moving column 13, and the outer wall of the slider 12 is fixedly connected to the inner wall of the moving column 13, and the upper and lower connecting plates 15 at the opposite ends are respectively rotatably connected to the opposite ends of the spray head 14, and the opposite ends of the upper and lower spray heads 14 are respectively rotatably connected to the upper and lower sides of the opposite end of the fixed frame 4.

[0035] Specifically: During the spraying process, the spray head 14 performs precise spraying operations by starting the second motor 9. The second motor 9 drives the reciprocating screw 11, which drives the slider 12 mounted on its outside, so that the slider 12 pushes the connected moving column 13 to move back and forth in the fixed shell 2. As the moving column 13 moves, the connecting plate 15 will also move accordingly, thereby driving the spray head 14 to rotate up and down along the position of the fixed frame 4. This design enables the spray head 14 to flexibly adjust the spraying angle and expand the coverage range of the spraying. In this way, the spray head 14 can not only fully cover parts of complex shapes, but also ensure the uniformity of paint coating on different parts, significantly improving the overall effect of paint spraying. This automated angle adjustment and coverage expansion not only reduces errors in manual operation, but also effectively improves production efficiency and coating quality, and meets the needs of modern manufacturing industries for high-precision and high-efficiency spraying processes.

[0036] Reference Figure 2 and Figure 7, as the stirring bin 5 for the function of mixing and stirring paint, a fixed pipe 6 is fixedly connected to the right end of the stirring bin 5, a first motor 7 is fixedly connected to the right end of the fixed pipe 6, and the driving end of the first motor 7 is respectively connected to a worm 19 and a chute pipe 20 through a gear set for driving the driving force of the first motor 7 to drive the chute pipe 20 and the worm 19 to rotate. A stirring rod 21 is slidably connected to the inner wall of the chute pipe 20, and a moving block 24 is connected to the outer wall of the worm 19 through a traction group for moving the stirring rod 21 when it rotates. The driving end of the first motor 7, a first gear 17 fixedly connected to the right end of the worm 19, and a second gear 18 fixedly connected to the right end of the chute pipe 20. The second gear 18 and the worm 19 are meshed. A worm gear 22 is meshed with the outer wall of the worm 19. A traction plate 23 is rotatably connected to the front outer wall of the worm gear 22. The left end of the traction plate 23 is rotatably connected to the front outer wall of the moving block 24. The bottom outer wall of the moving block 24 is slidably connected to the inner wall of the fixed pipe 6. The inner wall of the moving block 24 is rotatably connected to the left end outer wall of the stirring rod 21.

[0037] Specifically: When the first motor 7 is started, by driving the first gear 17, the second gear 18 starts to rotate. As the second gear 18 rotates, the worm 19 and the chute pipe 20 also rotate accordingly. The rotation of the worm 19 not only drives the worm gear 22 but also causes the traction plate 23 to move, thereby pulling the moving block 24 to linearly move along the fixed pipe 6. During this process, the worm 19 also drives the stirring rod 21 to move synchronously. When the moving block 24 pushes the stirring rod 21 to move, the stirring rod 21 starts to rotate and move back and forth in the stirring bin 5. This operation ensures that the paint mixture in the stirring bin 5 can be fully and evenly stirred. Through this fine stirring process, the paint ratio in the stirring bin 5 can reach an ideal uniform state, making it more in line with the production requirements during spraying.

[0038] Working principle: When the infusion water pump 8 starts, it pumps the paint in the stirring bin 5 through the infusion pipe 10 and sprays the paint to the part through the spray head 14. The circulating fan 25 in the hot air bin 3 inhales air and the heating wire 16 generates heat to form hot air, and the hot air in the hot air bin 3 is sprayed towards the spraying bin 1 to dry the tool. When the spray head 14 is spraying, the second motor 9 is started to make the reciprocating lead screw 11 drive the slider 12 sleeved outside it, and the slider 12 drives the moving column 13 to reciprocate in the fixed shell 2, and the moving column 13 drives the spray head 14 to rotate up and down along the fixed frame 4 through the connecting plate 15, so as to adjust the spraying angle of the spray head 14, expand the spraying range and improve the paint spraying effect. When the first motor 7 starts, it drives the first gear 17 to make the second gear 18 rotate, so that the worm 19 and the chute pipe 20 rotate. The worm 19 drives the worm wheel 22 to make the traction plate 23 traction the moving block 24 to move in the fixed pipe 6, and the worm 19 drives the stirring rod 21 to move, and the moving block 24 drives the stirring rod 21 to move, so that the stirring rod 21 rotates and moves at the same time, and the stirring rod 21 mixes the proportioned paint in the stirring bin 5 evenly, so that the paint meets the production requirements when spraying.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
