In order to facilitate people's lives, people have invented various types of glasses, and glasses have become a necessity in people's lives. The most critical part of glasses is the lens. The lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. After polishing, it is often assembled with glasses frames to form glasses. It is used to correct the user's vision and obtain a clear field of vision. Because the degree of each person's eyes is different, each lens needs to be precisely polished to ensure that it is suitable for personal use.

[0023] Furthermore, a driving rod 82 is installed on the inner wall of the movable plate 81 through a bearing, one end of the driving rod 82 passes through and extends to the back side of the movable plate 81, an adjusting gear 83 is fixedly sleeved on the outer surface of one end of the driving rod 82, and a first servo electric cylinder 84 is fixedly installed on the back side of the movable plate 81. The rotation of the adjusting gear 83 drives the driving rod 82 to rotate, and the driving rod 82 is positioned and rotated through the cooperation of the bearing.

[0024] Furthermore, one end of the piston rod of the first servo electric cylinder 84 is fixedly connected to a rack 85, the tooth surface of the rack 85 meshes with the tooth surface of the adjusting gear 83, and the other end of the driving rod 82 is fixedly connected to a swing support plate 86. The telescopic movement of the piston rod of the first servo electric cylinder 84 drives the rack 85 to move, and the movement of the rack 85 drives the meshing adjusting gear 83 to move. Through the cooperation between the rack 85 and the adjusting gear 83, the driving rod 82 is driven to perform precise rotation adjustment.

[0025] Furthermore, a top plate 87 is fixedly connected to the front of the swing support plate 86, a second servo electric cylinder 88 is fixedly installed on the inner wall of the top plate 87, one end of the piston rod of the second servo electric cylinder 88 is fixedly connected to a mounting frame 89, the swing support plate 86 drives the top plate 87 to swing and adjust, and the second servo electric cylinder 88 drives the mounting frame 89 to adjust the longitudinal height.

[0029] Working principle: Step 1, place the lens to be polished on the vacuum suction cup 3 to fix it, then drive the fixed lens to rotate by rotating the rotating base 2, start the second servo motor 810 to drive the rotating shaft 811 to rotate, the rotation of the rotating shaft 811 drives the grinding disc 812 to rotate, then start the piston rod of the second servo electric cylinder 88 to extend, thereby driving the mounting frame 89 to move downward, so that the rotating grinding disc 812 moves downward to contact the lens for polishing;

[0030] Step 2: When grinding the raised curved surface as a whole, start the piston rod of the first servo electric cylinder 84 to extend, and the extension of the piston rod of the first servo electric cylinder 84 drives the rack 85 to move, and the movement of the rack 85 drives the driving rod 82 to rotate through the meshing adjustment gear 83, and the rotation of the driving rod 82 drives the top plate 87 to rotate through the swing support plate 86, thereby driving the grinding disc 812 to adjust the angle;

The rotation of the screw 7 guides and limits the threaded block 8 through the guide moving groove 5, so that the threaded block 8 drives the moving plate 81 to move. The movement of the moving plate 81 drives the grinding disc 812 to move horizontally through the cooperation of the swing support plate 86 and the top plate 87, so as to cooperate with the angle adjustment of the grinding disc 812, and through the telescopic cooperation of the piston rod of the second servo electric cylinder 88, the grinding disc 812 is always in contact with the convex curved surface of the lens when the angle is adjusted, thereby realizing the grinding and polishing of the curved surface of the lens.
