Technical Field

[0001] The utility model relates to the technical field of lens production, in particular to an optical lens production clamping structure. Background Art

[0002] Optical lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. After polishing, it can be used to make glasses, magnifying glasses, and assembled on various telescopes and instruments. Because different devices require different polishing sizes and shapes, each optical lens needs to be fixed with a clamping mechanism to ensure that it is accurately polished to ensure that it is suitable for use in various devices.

[0003] At present, the traditional lens grinding method requires re-clamping after the outer edge of the lens is polished because the clamping mechanism of the lens grinding device clamps the lens, and the re-clamping requires re-positioning, which is not only cumbersome and time-consuming, but also has positioning errors, resulting in low precision of the two processing and grinding.

[0024] The top of the connecting plate 6 is connected to the slide groove set on the top of the bracket body 1, and a sliding structure is formed between the connecting plate 6 and the threaded rod 5. The driving motor 3 drives the threaded rod 5, and the connecting plate 6 set on the surface of the threaded rod 5 drives the connecting rod 11 to slide. After polishing, it returns to its original position through the threaded rod 5, forming a circulation state.

[0025] The clamping mechanism 4 includes a slider 401, a servo electric cylinder 402, an air pump 403, a suction cup 404 and a ratchet 405. The slider 401 is connected by a connecting rod 11, and a servo electric cylinder 402 is arranged below the slider 401. A suction cup 404 is connected below the servo electric cylinder 402. An air pump 403 is arranged above the slider 401. A ratchet 405 is arranged on the top of the suction cup. The air pump 403 tightens the suction cup 404 to fix the optical lens. The servo electric cylinder 402 presses the lens against the elastic telescopic rod 7 to accurately position it.

[0026] The elastic telescopic rod 7 includes a rotating motor 701, a rod sleeve 702, a compression spring 703, a connecting block 704, a support plate 705, a rubber pad 706 and a pulley 707. The rotating motor 701 is arranged above the base plate 2, and the rotating motor 701 and the base plate 2 are fixed by bolts. The compression spring 703 is connected to the top of the rotating motor 701, and the rod sleeve 702 is arranged on the outside of the compression spring 703. The support plate 705 is installed on the top of the compression spring 703, and the support plate 705 and the compression spring 703 are connected by a connecting block 704. The support plate 705 is pasted with a rubber pad 706, and pulleys 707 are installed on both sides of the bottom of the rotating motor 701. The rotating motor 701 drives the support plate 705 to rotate the lens in the clamping mechanism 4 above it, and the surface of the support plate 705 is installed with a rubber pad 706 for protecting the lens.

[0027] A snap button is provided on the top surface of the bottom plate 2, which is used to locate the placement position of the elastic telescopic rod 7 after the upper clamping mechanism 4 returns to reduce positioning deviation.

[0028] Working principle: When using the optical lens production clamping structure, first, place the optical lens in the suction cup 404 in the clamping mechanism 4, and the servo electric cylinder 402 arranged above the suction cup 404 presses the bottom of the optical lens against the top surface of the elastic telescopic rod 7, compressing the compression spring 703 to the specified position, and the air pump 403 above the slider 401 draws out the air in the suction cup 404 to fix it.

[0029] Secondly, turn on the power, and the driving motor 3 set on the top of the bracket body 1 drives the threaded rod 5 to rotate, so that its connecting plate 6 drives the connecting rod 11 to slide, and drives the slider 401 set on the surface of the connecting rod 11. The end of the connecting rod 11 is connected to the limit plate 10, and the rear of the limit plate 10 is a spring to increase its moving length.

[0030] Next, the rotating motor 701 at the bottom of the elastic telescopic rod 7 drives the connecting block 704 installed on the top of the compression spring 703, and a rod sleeve 702 is provided on the outside of the compression spring 703 to protect the safe operation of the compression spring 703. The connecting block 704 then drives the support plate 705 and the rubber pad 706. The surface of the rubber pad 706 contacts the optical lens to make it rotate, and a pulley 707 is provided on the top of the bottom plate 2. The pulley 707 is set in the corresponding slide groove at the bottom of the elastic telescopic rod 7, so that when the clamping device 4 moves toward the grinding equipment, it can drive the elastic telescopic rod 7 to move together.

[0031] Finally, after the edge is polished by the grinding wheel inside the polishing wall 8, the servo electric cylinder 402 contracts to separate the elastic telescopic rod 7 from the clamping mechanism 4. After the elastic telescopic rod 7 loses power, it will be recovered to the space below the grinding disc 9, and the optical lens fixed by the clamping mechanism 4 continues to move toward the grinding disc 9. The grinding disc 9 has a different rotation direction from the rotating motor 701, so that the ratchet 405 can only rotate in one direction and be polished by it. The unique size set between the polishing wall 8 and the grinding disc 9 allows the second lens to wait at the rear while the third lens is being polished on the outside. After all are completed, they are brought back to their original positions via the threaded rod 5 to circulate, and a plurality of clamping mechanisms 4 are installed on the connecting rod 11 to increase production output. A snap is provided on the top surface of the bottom plate 2 to position the placement of the elastic telescopic rod 7 after the upper clamping mechanism 4 returns to reduce positioning deviation, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
