Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a polishing mechanism for contact lens processing, comprising a base 1, a contact lens buckle 15 and a polishing liquid storage cup 17. A lifting cylinder 2 is fixedly connected to the top of the base 1, a piston top of the lifting cylinder 2 is fixedly connected to a limit seat 3, a motor 4 is fixedly connected to the top of the limit seat 3, a driving rod 5 is fixedly connected to the bottom of the output shaft of the motor 4, a rubber belt 6 is arranged on the outside of the driving rod 5, a driven block 7 is arranged on the rubber belt 6, the driving rod 5 is transmission-connected to the driven block 7 through the rubber belt 6, a rotating rod 8 is fixedly connected to the driven block 7, and a clamping block 9 is fixedly connected to the bottom of the rotating rod 8.

[0021] Furthermore, the piston of the lifting cylinder 2 is fixedly connected to the limit seat 3, so that after the lifting cylinder 2 is started, it can drive the limit seat 3 to move up and down, and the limit seat 3 can drive the rotating rod 8 and the clamping block 9 to move synchronously. The clamping block 9 can clamp and fix the contact lens buckle 15, thereby driving the contact lens buckle 15 and the contact lens body 16 to rotate.

[0022] Furthermore, the output shaft of the motor 4 is fixedly connected to the driving rod 5, so that the motor 4 can drive the driving rod 5 to rotate after it is started. The friction coefficient between the driving rod 5 and the driven block 7 and the rubber belt 6 is much larger than the friction coefficient between the rotating rod 8 and the limiting seat 3, and the fitting degree between the rotating rod 8 and the limiting seat 3 is high, and the friction loss is small, thereby ensuring the stability of the rotation of the rotating rod 8, the clamping block 9, the contact lens buckle 15 and the contact lens body 16, thereby ensuring the polishing accuracy of the contact lens body 16 by the polishing seat 10.

[0023] Furthermore, the first annular groove 501, the third annular groove 701 correspond to one of the rubber belts 6, and the second annular groove 502, the fourth annular groove 702 correspond to another rubber belt 6, so that when the driving rod 5 rotates, the two driven blocks 7, the rotating rod 8 and the clamping block 9 can be driven to rotate through the two rubber belts 6 respectively, and the clamping block 9 plays the role of clamping and fixing the contact lens buckle 15.

[0024] Furthermore, the polishing seat 10 serves to polish the contact lens body, the baffle 11 serves to intercept the splashed polishing liquid, the discharge pipe 12 serves to discharge the polishing liquid in the baffle 11, the placement plate 13 serves to place the receiving cup 14, the receiving cup 14 serves to temporarily store the polishing liquid, and the polishing liquid storage cup 17 serves to store the polishing liquid.

[0025] Embodiment 1:

[0026] When polishing two contact lens bodies 16 at the same time, two rubber belts 6 are wound around the driving rod 5 and two driven blocks 7. When polishing only one contact lens body 16, only one rubber belt 6 needs to be wound around the driving rod 5 and one of the driven blocks 7.

[0027] Embodiment 2:

[0028] The contact lens buckle 15 with the contact lens body 16 is clamped and fixed on the clamping block 9, and polishing liquid is added to the polishing seat 10 through the polishing liquid storage cup 17. The motor 4 is started, and the driving rod 5 drives the driven block 7, the rotating rod 8, the clamping block 9, the contact lens buckle 15 and the contact lens body 16 to rotate through the rubber belt 6. The lifting cylinder 2 drives the limit seat 3 to move downward, so that the contact lens body 16 in the rotating state contacts with the polishing seat 10, so as to polish the contact lens body 16. The fit between the rotating rod 8 and the limit seat 3 is high, and the friction loss is small, so that the rotation stability of the rotating rod 8, the clamping block 9, the contact lens buckle 15 and the contact lens body 16 is guaranteed, thereby ensuring the polishing accuracy of the contact lens body 16.
