During the intermittent rotation, the drying component 5 performs a comprehensive drying operation on the outer surface. Then, after the drying operation is completed, the shark fin is ejected by the positioning and rotating component 4 to demold the automobile plastic shark fin.

[0034] The control box 3 mentioned above is a mature control technology means and equipment in the prior art. In this solution, its controllable functions are utilized, and its internal structure, principle and connection method are not further elaborated.

[0035] Specifically, in order to achieve the positioning and intermittent rotation of the plastic shark fin on the car, refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 In this embodiment, the positioning and rotation assembly 4 includes a servo motor 41 fixedly connected to the right front end of the base 1, a conveying mechanism 42 is provided at the upper end of the base 1, a positioning mechanism 43 and an intermittent rotation mechanism 44 are provided on the inner surface of the base 1, an ejection mechanism 45 is provided on the inner surface of the positioning mechanism 43, and a protective mechanism 46 is symmetrically provided on the left and right inner surface of the base 1.

[0036] For further information, see Figure 3 and Figure 4 In this embodiment, the conveying mechanism 42 includes two rotating rods 421 rotatably connected to the inner surface of the base 1. The front end of the right rotating rod 421 is fixedly connected to the output end of the servo motor 41 through a coupling. The outer surfaces of the two rotating rods 421 are symmetrically wrapped with conveyor belts 422. The ends of the two conveyor belts 422 close to each other are commonly fixedly connected to a fixed plate 423, and the inner surface of the fixed plate 423 is rotatably connected to a rotating ring 424.

[0037] For further information, see Figure 3 、 Figure 5 and Figure 7 In this embodiment, the positioning mechanism 43 includes a hollow rod 431 fixedly connected to the inner surface of the rotating ring 424, the inner surface of the hollow rod 431 is rotatably connected to a round block 432, the inner surface of the round block 432 is fixedly connected to a cylinder 433, the inner surface of the cylinder 433 is slidably connected to a piston rod 434, the upper end of the rotating ring 424 is fixedly connected to a round hole airbag 435, the inner surface of the cylinder 433 is fixedly connected to a connecting tube 1 436, the outer surface of the connecting tube 1 436 is rotatably connected to a connecting tube 2 437 fixedly connected to the inner surface of the round hole airbag 435, the lower end of the piston rod 434 is fixedly connected to a roller 4310, the lower part of the inner surface of the base 1 is fixedly connected to a guide rail 4311, the upper end of the guide rail 4311 is fixedly connected to two limit plates 4312, and the outer surface of the piston rod 434 is provided with a return spring 4313, the two ends of the return spring 4313 are respectively fixedly connected to the piston on the piston rod 434 and the inner surface of the cylinder 433.

[0038] During the implementation process, the automobile plastic shark fin is placed on the upper end of the rotating ring 424, and then the output end of the servo motor 41 is started to drive the rotating rod 421 to rotate through the coupling, and under the action of the winding connection, the fixed plate 423 on the conveyor belt 422 is driven to move to the left, thereby driving the automobile plastic shark fin to move to the left. During the movement, the roller 4310 at the lower end of the piston rod 434 will gradually move upward from the first inclined surface of the guide rail 4311, and be squeezed by the guide rail 4311, so that the piston rod 434 slides upward on the inner surface of the cylinder 433, and the return spring 4313 is in a stretched state, squeezing the air inside the cylinder 433 into the connecting tube 1 436 and into the connecting tube 2 437, and into the circular hole airbag 435, so that the circular hole airbag 435 is expanded, so that the outer surface of the circular hole airbag 435 can be tightly attached to the inner surface of the automobile plastic shark fin, thereby fixing the inner surface of the automobile plastic shark fin and avoiding contact with the outer surface of the painted automobile plastic shark fin, causing scratches and wear on the paint surface.

[0039] The servo motor 41 mentioned above is a mature driving technology means and equipment in the prior art. In this solution, its output end is used to rotate forward and reverse through a coupling, and it can stop in time after the set number of rotations is completed. Its internal structure, principle and connection method will not be explained again.

[0040] The circular hole airbag 435 is made of polyamide fiber, which is resistant to high temperatures and has good stability.

[0041] For further information, see Figure 3 and Figure 8 In this embodiment, the intermittent rotation mechanism 44 includes a concave frame 441 rotatably connected to the outer surface of the hollow rod 431, the concave frame 441 is slidably connected to the base 1, the outer surface of the hollow rod 431 is fixedly connected to the intermittent disk 442, the inner surface of the concave frame 441 is rotatably connected to the transmission rod 446, the upper end of the transmission rod 446 is fixedly connected to the round rod disk 443, the upper end of the round rod disk 443 is fixedly connected to the notched disk 444, the upper end of the concave frame 441 is rotatably connected to the limiting rod 445, the square block at the upper end of the concave frame 441 is fixedly connected to the spring sheet 449 fixedly connected to the limiting rod 445, the outer surface of the transmission rod 446 is fixedly connected to the gear 448 through a one-way bearing, and the upper end of the front limiting plate 4312 is fixedly connected to the rack 447 meshing with the gear 448.

[0042] During implementation, after the plastic shark fin is inflated and fixed by the round hole airbag 435, it will continue to move to the left. When the gear 448 on the transmission rod 446 is engaged with the rack 447, the gear 448 will drive the round rod disk 443 to rotate, so that the round rod on the round rod disk 443 will rotate into the inner surface of the intermittent disk 442. As the round rod disk 443 rotates one circle, the intermittent disk 442 will rotate a certain angle once, and the bevel on the round rod disk 443 will be tightly attached to the outer surface of the limiting rod 445. When the outer surface of the limiting rod 445 is tightly attached to the arc edge on the round rod disk 443, the round rod disk 443 will squeeze the arc block on the limiting rod 445 and fit it tightly. On the arc surface of the intermittent disk 442, and at this time the spring sheet 449 is in a compressed state, realizing the limited fixation of the round rod disk 443, each rotation of the round rod disk 443 will drive the hollow rod 431 to rotate on the fixed plate 423, realizing intermittent rotation of the rotating ring 424, and the fixed plastic shark fin can continuously change the angle during the drying process, so that the paint surface of the shark fin can be evenly heated in all directions, effectively avoiding the difference in drying degree caused by local uneven heating, reducing the appearance of mottled and sagging on the paint surface, improving the drying effect and the stability of the paint surface quality, helping to improve drying efficiency, reduce drying time, and improve the overall production efficiency of the painting operation.

[0043] The gear 448 is engaged with the rack 447 to drive the intermittent disk 442 to rotate two complete circles.

[0044] For further information, see Figure 3 、 Figure 5 and Figure 6 In this embodiment, the ejection mechanism 45 includes a hollow cylinder 451 fixedly connected to the inner surface of the round block 432, the inner surface of the hollow cylinder 451 is slidably connected to the ejection rod 452, and the lower part of the inner surface of the cylinder 433 passes through and extends to the inner surface of the hollow cylinder 451 and is fixedly connected to the air pipe 453.

[0045] During the implementation process, when the drying operation is completed, the roller 4310 at the lower end of the piston rod 434 will contact the second inclined surface of the guide rail 4311. At this time, the piston rod 434 will move downward under the reaction of the return spring 4313, squeezing the air in the cylinder 433 into the hollow cylinder 451 through the air pipe 453. Under the action of air compression, the ejector rod 452 is pushed to slide upward on the inner surface of the hollow cylinder 451, so that the ejector rod 452 extends into the inner surface of the car shark fin. At this time, the round hole airbag 435 continues to shrink and no longer fixes it. The ejector rod 452 ejects the car shark fin after the drying operation to achieve unloading, effectively avoiding damage to the paint surface of the car shark fin caused by scratches, stains, etc. caused by human contact, and maintaining the integrity and beauty of the paint surface to the greatest extent. The ejector rod 452 extends into the inner surface of the shark fin to achieve ejection, which will neither damage the appearance of the shark fin nor have an adverse effect on its internal structure, thereby ensuring the stability of product quality.

[0046] For further information, see Figure 3 and Figure 9 In this embodiment, the protective mechanism 46 includes a fixed round rod 461 fixedly connected to the inner surface of the base 1, a spring 462 fixedly connected to the outer surface of the fixed round rod 461, one end of the spring 462 fixedly connected to a protective cloth 463, and a connecting plate 464 fixedly connected to the protective cloth 463 is slidably connected to the inner surface of the base 1.

[0047] From the above, it can be seen that the left and right movement of the hollow rod 431 will drive the connecting plate 464 to slide on the inner surface of the base 1, so that the protective cloth 463 can always be in a taut state under the deformation force of the spring 462, preventing the hot air from entering the inner cavity of the base 1 during the drying process, and providing stable airflow movement for the drying operation of the car shark fin.

[0048] Embodiment 2: Based on the embodiment 1, this embodiment adds a drying component 5 for drying automobile plastic parts in all aspects, thereby achieving the purpose of drying automobile plastic parts in all aspects.

[0049] Specifically, in order to fully dry automotive plastic parts, refer to Figure 3 and Figure 10 In this embodiment, the drying component 5 includes a hot air box 51 fixedly connected to the upper end of the base 1, an angle mechanism 52 is provided at the front end of the hot air box 51, and a follower mechanism 53 is provided on the inner surface of the shell 2.

[0050] For further information, see Figure 3 and Figure 10In this embodiment, the angle mechanism 52 includes an air outlet pipe 521 fixedly connected to the front end of the hot air box 51, one end of the air outlet pipe 521 is fixedly connected to a soft bellows 522 fixedly connected to the outer shell 2, and one end of the soft bellows 522 is fixedly connected to an angle tube 523.

[0051] For further information, see Figure 3 and Figure 10 In this embodiment, the follower mechanism 53 includes a slide rod 531 that is slidably connected to the upper inner surface of the shell 2, a fixed rod 532 is fixedly connected to the upper end of the front conveyor belt 422, the upper end of the fixed rod 532 and the lower end of the slide rod 531 are fixedly connected to magnets 534, and the left and right ends of the slide rod 531 are symmetrically fixedly connected to the disengagement rods 533.

[0052] During the implementation process, in order to allow the plastic shark fin of the car to be exposed to hot air throughout the process of the base 1 moving to the left, when the fixed rod 532 moves to the left with the conveyor belt 422, when the magnet 534 at the upper end of the fixed rod 532 and the magnet 534 at the lower end of the slide rod 531 attract each other, the fixed rod 532 will drive the slide rod 531 to slide on the inner surface of the shell 2, so that the slide rod 531 will drive the angle tube 523 to move with the fixed car shark fin, start the hot air box 51 to generate hot air of suitable temperature, and enter the angle tube 523 through the outlet pipe 521 and the soft bellows 522. When the rod 531 moves to the far left, the disengagement rod 533 on the left side of the slide rod 531 will contact the inner surface of the shell 2, and the fixed rod 532 will continue to move to the left. Under the blocking action of the disengagement rod 533 and the shell 2, the slide rod 531 and the fixed rod 532 are disengaged. Combined with the intermittent rotation of the car shark fin, the car plastic shark fin can be exposed to hot air throughout the movement to the left, allowing the hot air to blow evenly to various surfaces of the shark fin, which helps to evenly dry the paint surface. Through the layout of the angle tube 523, the hot air can more comprehensively contact the car plastic shark fin, reducing drying dead corners and improving the drying effect and quality.

[0053] The angle tubes 523 mentioned above are three tubes, and the angles formed with the rotating ring 424 are 30 degrees, 60 degrees and 90 degrees respectively.

[0054] The hot air box 51 mentioned above is a mature hot air generating technical means and equipment in the prior art, and its internal structure, principle and connection method are no longer described in this solution.

[0055] Working process: When in use, the shark fin of the car is placed in the positioning mechanism 43, and the inner surface of the shark fin of the car is fixed during the conveying process of the conveying mechanism 42 to achieve non-contact paint surface. In the process of conveying, the intermittent rotation mechanism 44, the angle mechanism 52 and the follow-up mechanism 53 are used to achieve intermittent angle rotation and comprehensive drying of the shark fin of the car. After the drying operation is completed, the shark fin of the car can be ejected by the ejection mechanism 45 to achieve unloading.
