Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens manufacturing technology, and in particular to a jig for lens manufacturing and processing. Background Technology
[0002] In the field of optical manufacturing, lenses, as core optical components, are widely used in imaging, communication, laser processing, and many other industries. During lens production and processing, the performance of the fixtures plays a crucial role in product quality and production efficiency. With the rapid development of optical technology, market demands for lenses are becoming increasingly diversified, requiring not only higher optical precision but also designs that meet different shapes and sizes.
[0003] Currently, most lens manufacturing fixtures on the market adopt a traditional fixed structure design. These fixtures typically consist of a base, a fixed clamping plate, and a clamping device. The shape and size of the fixed clamping plate are customized according to the specific lens profile and specifications, and the lens is fixed between the clamping plates by bolts, nuts, or pneumatic clamping mechanisms.
[0004] However, with continuous innovation in optical products, lens shapes are increasingly becoming asymmetrical and irregular, such as aspherical lenses, freeform lenses, and complex prism structures. Traditional fixed-structure jigs exhibit significant limitations when dealing with these complex-shaped lenses. Due to the fixed shape of their clamping plates and the fixed clamping method, it is difficult to accurately position asymmetrical and irregularly shaped lenses. In actual processing, misalignment frequently occurs, causing the lens to lose its correct posture during processing. Furthermore, because the jig cannot perfectly conform to the irregular contours of the lens, it is prone to suspended support, causing the lens to wobble or even fall out of the jig when subjected to cutting forces or grinding pressure. Therefore, a new jig for lens manufacturing is proposed to address these problems. Utility Model Content

This avoids the problem that traditional fixed structure fixtures are only suitable for lenses of specific shapes.

This avoids the problem that traditional fixed-size fixtures can only be used for lenses of a single specification. When processing different sizes, the machine needs to be stopped to change the fixture, which wastes time and affects the continuity of production. In addition, if the clamping range is too small, the lens cannot be fixed stably. If it is too large, the clamping force will be concentrated and damage the edge of small-sized lenses. This improves production efficiency and flexibility, increases clamping stability and processing accuracy, and reduces fixture costs. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a lens manufacturing fixture, including a worktable 1, a clamping plate 2 on the top of the worktable 1, a clamping assembly on the top of the worktable 1, and a fixing assembly on the outer wall of the clamping plate 2. The fixing assembly includes a sliding block 5, which is a C-shaped block structure used to connect the clamping plate 2 and a guide rail 4, enabling the clamping plate 2 to slide and adjust horizontally to flexibly adapt to different lens widths. The outer wall of the sliding block 5 is located on the outer wall of the clamping plate 2, and a fixing block 3 is fixedly connected to the outer wall of the clamping plate 2. The inner wall of the fixing block 3 is slidably connected to the guide rail 4. The fixing block 3 and the guide rail 4 cooperate to form a linear sliding pair, allowing the sliding block 5 to slide along the inner wall of the fixing block 3. Sliding adjustment is achieved to adapt to different lenses. The outer wall of sliding block 5 is fixedly connected to the outer wall of guide rail 4. The inner wall of sliding block 5 is slidably connected to guide rail 6. The outer wall of guide rail 6 is fixedly connected to sliding block 7. The inner wall of sliding block 7 is slidably connected to guide rail 8. The outer wall of guide rail 8 is fixedly connected to sliding block 9. Sliding blocks 5, 7, and 9 work together with guide rail 4, 6, and 8 to rotate and adjust, thus adapting to lenses of different shapes and increasing the versatility of the equipment. The outer wall of sliding block 9 is fixedly connected to pad 10, which is used to buffer the clamping force of the clamping plate 2 on the lens, avoid rigid contact damage to the lens surface, and effectively disperse pressure.
[0036] Reference Figure 1 , Figures 3-6 The clamping assembly includes a movable block 19, which carries and moves the clamping plate 2 along the slide rail 20 to achieve the clamping and releasing action of the lens. The outer wall of the movable block 19 is set on the top of the worktable 1. A connecting plate 11 is fixedly connected to the top of the worktable 1, and a frame 12 is fixedly connected to the top of the connecting plate 11. The connecting plate 11 and the frame 12 provide stable support for the entire clamping assembly, preventing shaking during the fixing process and increasing the stability of the equipment operation. A fixing frame 21 is fixedly connected to the inner wall of the frame 12, and the slide rail 20 is fixedly connected to the bottom of the fixing frame 21. The inner wall of the movable block 19 is slidably connected to the outer wall of the slide rail 20. A fixed frame 13 is fixedly connected to the base of the fixed frame 13. An electric push rod 14 is fixedly connected to the output end of the electric push rod 14. A push block 15 is fixedly connected to the outer wall of the push block 15. A connecting arm 17 is rotatably connected to the outer wall of the rotating arm 16. A rotating column 18 is rotatably connected to the inner wall of the connecting arm 17. The top of the rotating column 18 is fixedly connected to the bottom of the moving block 19. When the output end of the electric push rod 14 extends or retracts, the push block 15 pushes the connecting arm 17 to swing. In conjunction with the rotating columns 16 and 18, this causes the moving block 19 to move linearly along the slide rail 20, thus converting the extension and retraction motion of the electric push rod 14 into the linear motion of the moving block. This achieves the effect of clamping or releasing the lens. A connecting plate 22 is fixedly connected to the top of the moving block 19. A connecting arm 21 is fixedly connected to the top of the connecting plate 22. A connecting post 30 is rotatably connected to the inner wall of the connecting arm 21. A rotating block 28 is fixedly connected to the bottom of the connecting post 30. A fixing post 39 is fixedly connected to the inner wall of the rotating block 28. The bottom of the fixing post 39 is fixedly connected to the outer wall of the clamping plate 2. A fixing post 27 is rotatably connected to the inner wall of the rotating block 28. A rotating block 1 26 is fixedly connected to the bottom of the fixing post 27. A fixing post 1 25 is rotatably connected to the inner wall of the rotating block 1 26. The rotating blocks 1 26, 28, 1 25, and 25 are connected to each other. The cooperation of the second 27 and the third 29 with the fixed column achieves the transfer of the movement of the moving block 19 to the clamping plate 2, achieving the effect of fixing lenses of different sizes and increasing the versatility of the equipment. The bottom of the first 25 is fixedly connected to the third 22, the outer wall of the third 22 is fixedly connected to the outer wall of the frame 12, the top of the third 22 is fixedly connected to the guide block 23, the inner wall of the guide block 23 is slidably connected to the guide column 24, one end of the guide column 24 is fixedly connected to the outer wall of the clamping plate 2, the guide column 24 cooperates with the guide block 23 to move linearly, avoiding shaking during the clamping of the lens, which would prevent the lens from being fixedly fixed, thus increasing the stability of the equipment.
[0037] Working principle: When fixing lenses of different shapes, the clamping plate 2 first moves the fixing block 3, which in turn moves the guide rail 4. Then, the guide rail 4 moves the sliding block 5, which in turn moves the guide rail 6. The guide rail 6 then moves the sliding block 7, which in turn moves the guide rail 8. The guide rail 8 then moves the sliding block 9, which in turn moves the pad 10 to fix the lens. The guide rails 4, 6, and 8 slide on the inner walls of the fixing block 3, sliding block 5, and sliding block 7 to fix lenses of different shapes. This avoids the problem that traditional fixing fixtures are only suitable for lenses of specific shapes. For asymmetrical or irregularly shaped lenses, the complex contours make precise positioning difficult, which can lead to problems such as misalignment, suspended support, and shaking or even falling off during processing.
[0038] When clamping and fixing lenses of different specifications, the electric push rod 14 first drives the push block 15 to move, then the movement of the push block 15 drives the rotating column 16 to move, then the movement of the rotating column 16 drives the connecting arm 17 to rotate, then the rotation of the connecting arm 17 drives the rotating column 18 to move, then the movement of the rotating column 18 drives the moving block 19 to slide on the outer wall of the slide rail 20, and then the movement of the moving block 19 drives the connecting plate 32 to move. The movement of 32 causes the second connecting arm 31 to move, which in turn causes the connecting column 30 to move. The movement of the connecting column 30 then causes the second rotating block 28 to rotate, which in turn causes the third fixed column 29 to move. The movement of the third fixed column 29 then causes the clamping plate 2 to clamp and fix the lens. The movement of the clamping plate 2 then causes the guide column 24 to slide on the inner wall of the guide block 23. The movement of the second rotating block 28 then causes the second fixed column 27 to move, which in turn causes the first rotating block 26 to rotate. The rotation of the first rotating block 26 on the outer wall of the first fixed column 25 causes the second rotating block 28 to rotate. This avoids the problem that traditional fixed-size fixtures can only accommodate lenses of a single specification. When processing different sizes, the machine needs to be stopped to change the fixture, which wastes time and affects the continuity of production. In addition, too small a clamping range will cause the lens to be unstable and fixed, while too large a clamping range will damage the edge of small-sized lenses due to concentrated clamping force.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
