[0053] The auxiliary plate 38 is also equipped with a pneumatic gripper 37, and the two grippers 371 of the pneumatic gripper 37 are located on both sides of the radial direction of the lens 9.

[0054] Before polishing, the suction head of the pneumatic suction cup 36 picks up the upper surface of the lens 9 and moves the lens 9 to the contour polishing mechanism 4. After polishing, the two claws 371 of the pneumatic gripper 37 move toward each other to clamp the peripheral wall of the lens 9 to avoid damaging the polished surface of the lens 9.

[0055] The cleaning and drying mechanism 5 includes a cleaning tank 51, a first nozzle 52, and a second nozzle 53.

[0057] After polishing, the pneumatic gripper 37 moves the lens 9 from the polishing table 11 to the cleaning tank 51. First, water is sprayed onto the lens 9 by nozzle 1 52, and then air is blown onto the lens 9 by nozzle 2 53 to dry it, thus cleaning the lens 9. Finally, the lens 9 is moved from the cleaning tank 51 to the unloading area 222 of the mounting box 22.

[0058] The implementation principle of an automatic polishing device for automotive resin lenses 9 according to an embodiment of this application is as follows:

[0059] The conveyor belt moves the mounting box 22 containing the lens 9 and the small iron 91 to below the moving frame 35 of the moving loading and unloading mechanism 3. Then, the second linear module 32, the third linear module 33, and the fourth linear module 34 work together to move the lens 9 and the small iron 91 from the loading area 221 of the mounting box 22 to the placement seat 12 of the polishing table 11. Then, the rotating seat 13 is driven to rotate by the rotating motor, thereby driving the small iron 91 and the lens 9 to rotate. Then, the sliding component 43 drives the swing arm 41 to move along the length direction of the polishing table 11 to above the lens 9. Then, the swing component 44 drives the swing arm 41 to swing along the curved surface of the lens 9. At the same time, the sliding plate 432 moves back and forth along the radial direction of the lens 9, so that the polishing shaft assembly 42 can polish the surface of the lens 9 along the curved surface of the edge of the lens 9.

[0060] After polishing, the pneumatic gripper 37 moves the lens 9 from the polishing table 11 to the cleaning tank 51. First, the nozzle 1 52 sprays water onto the lens 9, and then the nozzle 2 53 blows air onto the lens 9 to dry it, so as to achieve the purpose of cleaning the lens 9.

[0061] Finally, the lens 9 is moved from the cleaning tank 51 to the unloading area 222 of the mounting box 22.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
