Technical Field

[0001] The utility model relates to the technical field of lens fixing, in particular to a fixing device for lens edge grinding processing. Background Technique

[0002] After pouring, curing and demolding, a blank lens is obtained. Some foreign matters will remain on the edge of the demolded blank lens. Therefore, it is necessary to trim the edge of the blank lens to make it smooth. At present, when grinding the edge of the lens, it is not convenient to fix the blank lens after placing it. It is necessary to hold the blank lens by hand and then the clamping mechanism can be close to clamp the blank lens. There is a problem that it is not convenient to fix the blank lens after placing it.

[0027] A placing rack 21 is fixedly installed on the top of the workbench 1. A placing portion 22 for placing a blank lens is formed in the placing rack 21;

[0028] A first cylinder 8 is fixedly installed on the inner top of the workbench 1. A push block for pushing the push seat 18 is fixedly installed on the telescopic rod of the first cylinder 8.

[0029] In an alternative embodiment: The first cylinder 8 is arranged below the placing rack 21.

[0030] In an alternative embodiment: The driving mechanism includes a first driving motor 2 and a first rotating rod 3. The first driving motor 2 is fixedly installed on the inner top of the workbench 1. The output shaft of the first driving motor 2 is fixedly connected with the first rotating rod 3 through a coupling. The connecting seat 4 is fixedly installed at the upper end of the first rotating rod 3.

[0031] It should be noted that through the cooperation of the first driving motor 2 and the first rotating rod 3, the connecting seat 4 can be driven to rotate, so that when the connecting seat 4 rotates, it can drive the mounting seat 5 to rotate, so that the mounting seat 5 adsorbed with the blank lens can be moved below the clamping mechanism, and the blank lens is pressed and fixed by the clamping mechanism.

[0032] In an alternative embodiment: A plurality of positioning blocks 19 for positioning are uniformly arranged on the surface of the push seat 18 along the circumferential direction. A plurality of positioning grooves 20 corresponding to the positioning blocks 19 are formed in the inner wall of the movable ring 17. The positioning blocks 19 are inserted into the positioning grooves 20.

[0033] It should be noted that through the cooperation of the positioning blocks 19 and the positioning grooves 20, the positioning of the movable ring 17 can be realized, so that when the blank lens is rotated and adjusted, the cooperation of the positioning blocks 19 and the positioning grooves 20 can conveniently drive the movable ring 17 to rotate, so as to facilitate the edge grinding of the blank lens.

[0034] In an alternative embodiment: A bracket 12 is fixedly installed on the top of the workbench 1. A clamping mechanism is provided on the bracket 12. The clamping mechanism includes a second cylinder 13, a lifting rod 14, a second rotating rod 9 and a pressing disc 10. The second cylinder 13 is fixedly installed on the top of the bracket 12. The lifting rod 14 is fixedly installed on the telescopic rod of the second cylinder 13. The second rotating rod 9 is movably installed in the lifting rod 14.

[0036] It should be noted that through the cooperation of the second driving motor 7, the second rotating rod 9 and the pressing disc 10, the blank lens can be driven to rotate. Thus, when the blank lens is rotated and adjusted, a grinding device (not shown in the figure) can grind the blank lens.

[0037] In an alternative embodiment: The top of the lifting rod 14 is fixedly connected with a guide rod 24. The guide rod 24 is movably inserted into the bracket 12.

[0038] It should be noted that the lifting rod 14 can be positioned through the guide rod 24, so that the lifting rod 14 can move smoothly.

[0039] In an alternative embodiment: A second rubber pad 15 is provided on the inner top of the placing rack 21. The placing part 22 is arc-shaped.

[0040] It should be noted that through the setting of the second rubber pad 15, when the blank lens is adsorbed and fixed, the second rubber pad 15 can prevent the blank lens from being scratched and affecting the quality of the blank lens. By setting the placing part 22 to be arc-shaped, when the first driving motor 2, the first rotating rod 3, the connecting seat 4 and the mounting seat 5 cooperate to drive the blank lens to move, the blank lens can move out of the placing rack 21.

[0041] During specific use, first place the blank lens in the placing part 22. The placing part 22 can position the blank lens. By starting the first cylinder 8, the telescopic rod of the first cylinder 8 pushes the push block 25. After the push block 25 rises, it can push the push seat 18. When the push seat 18 moves up, it can push the suction cup 16. After the suction cup 16 contacts the bottom of the blank lens, the blank lens is lifted. When the blank lens contacts the second rubber pad 15, it is pressed against the placing rack 21, so that the blank lens can be adsorbed and fixed on the suction cup 16. The pre-fixation of the blank lens can be realized through the suction cup 16.

[0042] After the first cylinder 8 pushes the push block 25, by starting the first cylinder 8, the telescopic rod of the first cylinder 8 drives the push block 25 to return to its original position, and then the first driving motor 2 is started. The output shaft of the first driving motor 2 rotates to drive the first rotating rod 3 to rotate, so that when the first rotating rod 3 rotates, it can drive the connecting seat 4 to rotate. When the connecting seat 4 rotates, it drives the blank lens to move below the first rubber pad 11. By starting the second cylinder 13, the second cylinder 13 drives the lifting rod 14 to move, so that the first rubber pad 11 can be pressed tightly on the blank lens, thereby fixing the blank lens. By starting the second driving motor 7, the output shaft of the second driving motor 7 rotates to drive the first rubber pad 11 to rotate through the second rotating rod 9. When the first rubber pad 11 rotates, the blank lens can be rotationally adjusted. Thus, when the blank lens is rotationally adjusted, a grinding device (not shown in the figure) grinds the blank lens.
