Abstract
Description
Technical Field
[0001] This invention relates to the field of optical lens polishing technology, specifically to a polishing apparatus for optical lens processing. Background Technology
[0002] The optical lens polishing process aims to remove the surface damage layer left by the lens grinding process and precisely adjust the surface shape accuracy of the lens to meet the surface roughness, aperture number, and local aperture requirements specified in the design drawings. This results in a smooth, transparent optical working surface without obvious defects. For most optical lenses, both sides need to be polished with high precision to ensure that light has good transmission performance and wavefront quality when passing through the lens, thereby ensuring that the final image is clear and stable, and meeting the core image quality requirements of the optical system.
[0003] In existing technologies, when polishing optical lenses on both sides, the side surface of the lens is usually fixed by a clamping mechanism first, and a support device that matches the shape of the lower surface of the lens is used to stably support and limit the lens. Then, the upper polishing device polishes the locked upper surface of the lens. Since the two surfaces of the same lens often have different shapes, such as one side being convex and the other side being concave or flat, and even if the shape types are the same, their radii of curvature often differ, after polishing one side, it is usually necessary to replace the support device or transfer and fix the lens to another suitable support device to match the shape of the other surface of the lens. This ensures that the lens receives stable support and precise shape control during the polishing process, thereby ensuring that the final polishing quality meets the optical design requirements.
[0004] However, the traditional method of double-sided polishing of optical lenses has the following problems: 1. In the existing technology, the support structure currently used for lens polishing can often only match the surface shape and curvature of a specific lens. There is a lack of a support device that can flexibly adapt to different surface shapes. Therefore, when the first surface is polished and the other surface needs to be processed, the operator must replace the current support device or disassemble the lens and transfer it to another suitable support device. The above replacement or transfer process not only increases the proportion of non-processing time, but also leads to cumbersome process connections, reduced overall efficiency, and decreased economic benefits. At the same time, frequent disassembly and assembly operations may also introduce positioning errors, affecting the surface shape. 1. Inconsistent control can negatively impact polishing accuracy and production rhythm. 2. In existing technologies, support devices are typically designed specifically for the surface shape and diameter of a particular lens, resulting in poor versatility and difficulty in flexibly adapting to lenses of different diameters or surface shapes. Therefore, when switching between different lens models for polishing, it is often necessary to remanufacture or purchase corresponding dedicated support devices. This not only increases equipment procurement and customization costs but also brings additional warehousing and management burdens. At the same time, frequent tooling changes reduce the overall flexibility of the production line, especially limiting overall processing efficiency and economy in high-mix, small-batch production scenarios.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention, through the support mechanism, can flexibly adapt to optical lenses of different diameters, surface shapes, and radii of curvature, so as to provide precise and multi-point stable support for various types of optical lenses. Thus, the support adaptation required for double-sided polishing of various lenses can be completed with a single device, without the need to frequently change the support device or re-clamp the lens due to differences in lens surface shape or size. This significantly reduces non-processing and production interruption time, greatly improves polishing efficiency, ensures consistency in surface shape control, and reduces positioning errors caused by disassembly and assembly. At the same time, since the support mechanism of the present invention has good versatility and adaptive adjustment capabilities, it is not necessary to repurchase or customize special support components when switching to polishing different types of lenses. This saves equipment purchase and warehousing management costs and enhances the flexibility and economy of the production line in dealing with multi-variety, small-batch orders.
[0019] 2. This invention, through the cooperation of the support mechanism and the clamping mechanism, can achieve stable clamping and automatic flipping of the optical lens during the polishing process. It can complete the efficient conversion of the two sides of the lens and adaptive support without disassembling or replacing the clamps, thereby ensuring the continuity and efficiency of the double-sided polishing process of the optical lens and shortening the non-operation time.
[0020] 3. Through the locking mechanism, this invention can further integrate and reinforce the support mechanism and clamping mechanism into a whole after the support mechanism and clamping mechanism have completed the support, positioning and clamping of the optical lens, forming a synergistic and enhanced stable lock. This effectively improves the rigidity and anti-disturbance capability of the lens clamping lock, avoids micro-displacement caused by external force or vibration during the polishing process, and significantly improves the accuracy of surface shape control and the stability of the polishing process. At the same time, the locking mechanism and clamping mechanism can be matched and adjusted according to the diameter of different lenses to enhance the flexibility and adaptability to various lenses.

Detailed Implementation
[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Please see Figure 1 A polishing apparatus for optical lens processing includes a clamping table 2 and a polishing device 1. The clamping table 2 is provided with a clamping mechanism 4 and a supporting mechanism 3 distributed vertically. The clamping mechanism 4 is provided with a locking mechanism 5. The polishing device 1 for polishing optical lenses is provided above the clamping mechanism 4.
[0033] Please see Figure 1 The supporting mechanism 3 includes an adjustment and mating part 31 disposed on the clamping table 2 for lifting and rotating adjustment, a mating and mating part 32 disposed on the adjustment and mating part 31 for mating and supporting the lower surface of the optical lens, a mating and mating part 33 disposed on the mating and mating part 32 for matching and supporting the curved surface of the lens, and a mating and locking part 34 disposed on the mating and locking part 34 for cooperating with the locking mechanism 5 for locking and reinforcement.
[0034] Please see Figure 1 and Figure 2The adjusting and cooperating part 31 includes an electric push rod 311 fixedly installed on the lower side of the clamping table 2. The telescopic end of the electric push rod 311 is fixedly installed with a lifting platform 312 located above the clamping table 2. Multiple guide rods 1 that are slidably connected to the clamping table 2 are fixedly installed on the lower side of the lifting platform 312. Supports 1 are symmetrically fixedly installed on the upper side of the lifting platform 312. Rotary cylinders 313 are fixedly installed on opposite sides of the supports 1. A rotating platform 314 located between the supports 1 is fixedly installed between the drive ends of the symmetrically installed rotary cylinders 313.
[0035] The electric actuator 311 can drive the lifting platform 312 and the rotating platform 314 to move up and down for adjustment, and the rotary cylinder 313 can drive the rotating platform 314 to rotate at a fixed angle for adjustment.
[0036] Please see Figure 2 , Figure 3 and Figure 4 The docking support 32 includes three mounting slots 321 evenly opened on the rotating table 314 in the circumferential direction. Each mounting slot 321 is equipped with a support platform 322 by bolts. Taking the upper support platform 322 as an example, the upper support platform 322 is provided with locking slots 323 on both the left and right sides. The locking slots 323 distributed on the left and right sides are staggered vertically, with the right locking slot 323 on the upper side and the left locking slot 323 on the lower side.
[0037] When it is necessary to support an optical lens with a flat lower surface, the rotary table 314 can be rotated at a fixed angle by the rotary cylinder 313 until the right support table 322 is rotated to the upper side, so that the flat surface of the support table 322 away from the corresponding mounting groove 321 supports the lower surface of the optical lens.
[0038] Please see Figure 1 , Figure 3 and Figure 4 The mating part 33 includes a receiving groove 331 opened on the side of the upper and left support platform 322 away from the corresponding mounting groove 321. Taking the upper support platform 322 as an example, a support ring 332 is installed on the inner side of the receiving groove 331 of the upper support platform 322 by bolts. By replacing the support ring 332 with different inner diameters, it can adapt to optical lenses of different diameters. An adjustment groove 333 is opened on the lower side of the receiving groove 331 of the upper support platform 322. Multiple telescopic grooves 334 are evenly opened on the lower side of the adjustment groove 333. A support column 335 with a hemispherical upper end is elastically slidably arranged in the telescopic groove 334 by spring. The upper support column 335 is longer than the left support column 335. The hemispherical end of the support column 335 in the upper support platform 322 is located on the upper side of the corresponding receiving groove 331, and the hemispherical end of the support column 335 in the left support platform 322 is located on the inner side of the corresponding receiving groove 331.
[0039] When supporting and limiting an optical lens with a concave lower surface, the lens is first placed face down on the upper support platform 322 using the existing placement device. The concave lower surface of the lens then contacts the hemispherical end of the support column 335 extending from the corresponding receiving groove 331, causing the support column 335 to compress the spring downwards. Under the elastic action of the spring, the support column 335 also stably supports the concave lower surface of the lens through its hemispherical end until the outer edge of the lower side of the optical lens contacts and tightly adheres to the upper surface of the support ring 332. When the lenses are in contact, the clamping mechanism 4 can stably clamp and lock the optical lens by limiting its position on the side surface of the lens, thereby keeping the lens concentric with the corresponding receiving groove 331 and the supporting ring 332. Then, the locking mechanism 5 simultaneously and stably locks the supporting platform 322 and each support column 335 compressed by the concave surface of the lens, preventing them from moving up and down. At the same time, the clamping mechanism 4 is also locked simultaneously by the locking mechanism 5, thereby achieving stable clamping and locking of the optical lens and multi-point uniform and stable support of its lower concave surface.
[0040] When supporting and limiting an optical lens with a convex lower surface, the rotary cylinder 313 first rotates the rotary table 314 at a fixed angle until the left support platform 322 is rotated to the upper side. Then, the optical lens is placed on the support platform 322 with its convex surface facing down using the existing delivery device. The convex lower surface of the optical lens then contacts the hemispherical end of the support column 335 inside the corresponding receiving groove 331, causing the support column 335 to compress the spring downwards. Under the elastic action of the spring, the support column 335 also stably supports the convex lower surface of the lens through its hemispherical end until the outer edge of the lower side of the optical lens contacts and tightly adheres to the upper surface of the support ring 332. At this point, the clamping mechanism 4 can stably limit and clamp the side surface of the optical lens, thereby... The optical lens is stably clamped and locked, and its concentricity with the corresponding receiving groove 331 and supporting ring 332 is maintained. Then, the supporting platform 322 and each support column 335 compressed by the lens convex surface are simultaneously and stably locked by the locking mechanism 5, so that they cannot move up and down. At the same time, the clamping mechanism 4 is also locked simultaneously by the locking mechanism 5, thereby achieving stable clamping and locking of the optical lens and multi-point uniform and stable support of its lower convex surface. The support column 335 on the supporting platform 322 is relatively short, which can effectively reduce the deformation of the spring when the lens convex surface drives the support column 335 to compress the spring. Thus, while ensuring that the support column 335 is stably attached to the lens convex surface, the reaction force of the spring is effectively reduced, so as to ensure the relative stability of the optical lens during placement.
[0041] When polishing the surface on the other side of the optical lens, the locking mechanism 5 first releases the locking mechanism 4 and the corresponding support platform 322. Then, the electric push rod 311 moves the lifting platform 312 and the rotating platform 314 downward to make room. Next, the clamping mechanism 4 rotates the optical lens 180 degrees, and at the same time, the rotating cylinder 313 rotates the rotating platform 314 at a fixed angle until the support platform 322, which matches the shape of the polished surface of the optical lens, is rotated to the upper side. Then, the electric push rod 311 moves the rotating platform 314 upward to reset until the upper surface of the support ring 332 contacts and fits tightly with the outer edge of the polished surface on the lower side of the optical lens. Finally, the locking mechanism 5 locks the corresponding support platform 322, support column 335 and clamping mechanism 4 again, so that the polishing equipment 1 can stably polish the surface on the other side of the optical lens.
[0042] The above-described operation method can flexibly adapt to optical lenses of different diameters, surface shapes, and radii of curvature, providing precise and multi-point stable support for various types of optical lenses. Thus, a single device can complete the support adaptation required for double-sided polishing of multiple lenses, eliminating the need for frequent replacement of support devices or re-clamping of lenses due to differences in lens surface shape or size. This significantly reduces non-processing and production downtime, greatly improves polishing efficiency, ensures consistency in surface shape control, and reduces positioning errors caused by disassembly and assembly. Furthermore, since the support mechanism 3 of this invention has good versatility and adaptive adjustment capabilities, there is no need to repurchase or customize special support components when switching between different types of lenses for polishing. This saves on equipment purchase and warehousing management costs and enhances the flexibility and economy of the production line in handling multi-variety, small-batch orders.
[0043] For ease of description, it should be noted that the orientation of the docking locking part 34 in the following text will be explained using the upper side as an example.
[0044] Please see Figure 1 , Figure 4 and Figure 5 The docking locking part 34 includes a locking plate 341 that is slidably disposed in the adjustment groove 333 and distributed vertically. The locking plate 341 has a straight locking groove 342 that runs vertically through and extends horizontally. The locking plate 341 is elastically slidably connected to the adjustment groove 333 by a plurality of left-right symmetrical spring rods. The vertically distributed locking plates 341 correspond to the vertically staggered locking slots 323. The locking slots 323 have docking slots 343 that communicate with the adjustment groove 333 horizontally. The right support platform 322 has a receiving slot 344 in the locking slot 323, and the receiving slot 344 is longer than the docking slot 343.
[0045] Please see Figure 1 and Figure 6The clamping mechanism 4 includes a return frame 41 fixedly mounted on the upper side of the clamping table 2 by multiple L-shaped support plates. The return frame 41 is provided with a flip clamping part 42 for clamping and flipping the lens. The flip clamping part 42 is provided with a docking adjustment part 43 for cooperating with the locking mechanism 5 for adjustment and locking.
[0046] Please see Figure 6 and Figure 7 The flipping clamping part 42 includes an electric push rod 421 that is symmetrically fixed on the outside of the return frame 41. A rotary cylinder 422 is fixedly installed at the telescopic end of the electric push rod 421. A return frame 423 is fixedly installed at the driving end of the rotary cylinder 422. A sliding groove with internal and external through-holes is opened on the upper side of the return frame 423. A clamping head 424 is fixedly installed on the front side of the return frame 423.
[0047] When the optical lens placed on the corresponding support platform 322 needs to be clamped and locked, the two electric push rods 421 simultaneously drive the corresponding U-shaped frame 423 and the clamping head 424 to move towards the optical lens until the two clamping heads 424 cooperate to stably clamp and lock the front and rear sides of the optical lens. At the same time, it can also ensure that the clamped and fixed optical lens is concentric with the corresponding receiving groove 331 and the support ring 332. When the clamped and fixed optical lens needs to be flipped, the two rotary cylinders 422 simultaneously drive the corresponding U-shaped frame 423 and the clamping head to rotate 180 degrees, thereby causing the optical lens to flip 180 degrees.
[0048] The above operation method can achieve stable clamping and automatic flipping of the optical lens during the polishing process. It can complete the efficient conversion of the two sides of the lens and adaptive support without disassembling or changing the clamps, thereby ensuring the continuity and efficiency of the double-sided polishing process of the optical lens and shortening the non-operation time.
[0049] Please see Figure 6 and Figure 8 The docking adjustment part 43 includes a docking slide column 431 that is slidably disposed in the U-shaped frame 423 and moves back and forth. The docking slide column 431 has locking slots 432 symmetrically provided on the left and right sides. The upper side of the docking slide column 431 is fixedly provided with a threaded seat 433 that is slidably connected to the corresponding slide groove. The upper side of the U-shaped frame 423 is rotatably provided with an adjusting screw 434 that is threadedly connected to the corresponding threaded seat 433 through a support. A knob 435 is fixedly provided on the side of the adjusting screw 434 away from the corresponding clamping head 424.
[0050] Rotating the knob 435 drives the adjusting screw 434 to rotate synchronously, so that the adjusting screw 434 drives the docking slide 431 to move back and forth along the corresponding loop frame 423 through the screw transmission with the corresponding threaded seat 433.
[0051] Please see Figure 1 and Figure 6 The locking mechanism 5 includes a clamping and reinforcing part 51 disposed on the retractable frame 41 for clamping and reinforcing the lens. The clamping and reinforcing part 51 is provided with a supporting and locking part 52 for reinforcing and locking the docking support part 32 and the docking mating part 33, and a clamping and locking part 53 for reinforcing and locking the flipping clamping part 42.
[0052] Please see Figure 6 and Figure 9 The clamping and reinforcing part 51 includes electric push rods 3 511 that are symmetrically fixed on the outside of the return frame 41. A U-shaped frame 512 is fixedly installed at the telescopic end of the electric push rods 3 511. A guide rod 2 that is slidably connected to the return frame 41 is symmetrically fixed on the side of the U-shaped frame 512 close to the corresponding electric push rods 3 511. A clamping head 2 513 is fixedly installed on the opposite side of the U-shaped frame 512.
[0053] When it is necessary to reinforce the clamped optical lens, the electric push rod 3 511 drives the corresponding U-shaped bracket 512 and clamping head 2 513 to move towards the optical lens until the two clamping heads 2 513 also clamp and fix the left and right sides of the optical lens, thereby further reinforcing the optical lens.
[0054] Please see Figure 6 and Figure 9 The supporting locking part 52 includes an adjusting screw 521 connected to the lower side of the corresponding U-shaped frame 512 by a support three-thread connection. On the opposite side of the adjusting screw 521, a plug 522 is fixedly provided to engage with the corresponding locking slot 323. On the opposite side of the plug 522, a push rod 523 is fixedly provided to engage with the corresponding docking slot 343 or receiving slot 344 and to push with the corresponding locking plate 341.
[0055] When the electric actuator 511 drives the corresponding clamping head 513 to clamp and reinforce the optical lens, the U-shaped frame 512 moves synchronously through the support 3, driving the adjusting screw 521. The adjusting screw 521 then drives the bolt 522 to engage with the corresponding locking slot 323 on the support 322, thus locking the support 322 stably. The push rod 523 also engages with the bolt 522 and is inserted into the corresponding docking slot 343 or receiving slot 344. If the push rod 523 is engaged with the docking slot 343, the end of the push rod 523 away from the corresponding bolt 522 extends into the corresponding adjusting slot 33. Within 3, the corresponding locking plate 341 is pushed simultaneously, and the upper and lower distributed locking plates 341 move relative to each other, driving the corresponding ends of the linear locking grooves 342 to move towards the corresponding support column 335, until the two corresponding linear locking grooves 342 distributed vertically are tightly fitted with the side surface of the support column 335 through their corresponding ends, thereby cooperating to stably clamp and lock the corresponding support column 335, preventing it from moving up and down, and thus synchronously and stably locking the corresponding support platform 322 and each support column 335; after the top rod 523 resets and disengages from the corresponding locking plate 341, the spring rod drives the corresponding locking plate 341 to move and reset synchronously.
[0056] The rotating adjusting screw 521 can drive the corresponding bolt 522 and top rod 523 to move left and right through the three-helix transmission between the adjusting screw 521 and the corresponding support. This ensures that when the clamping head 513 and clamping head 424 clamp optical lenses of different diameters, the bolt 522 and top rod 523 can always stably lock and reinforce the support platform 322 and the support column 335.
[0057] Please see Figure 6 and Figure 9 The clamping and locking part 53 includes a support four that is symmetrically fixed on the U-shaped frame 512. An adjusting screw three 531 is threadedly connected to the support four. A plug two 532 that is fixedly provided on the side of the adjusting screw three 531 away from the corresponding electric push rod three 511 and is engaged with the corresponding locking slot two 432 for locking.
[0058] When the electric push rod 3 511 drives the corresponding clamping head 2 513 to clamp and reinforce the optical lens, the U-shaped frame 512 moves synchronously through the support 4, driving the adjusting screw 3 531. The adjusting screw 3 531 then drives the plug 2 532 to engage and insert into the corresponding locking slot 2 432 on the corresponding docking slide 431, thereby stably locking the corresponding docking slide 431 and the clamping head 1 424 on the U-shaped frame 423. The rotating adjusting screw 3 531 can drive the corresponding plug 2 532 to move left and right through the screw drive of the adjusting screw 3 531 and the corresponding support 4, and simultaneously drive the docking slide 431 to move back and forth through the adjusting screw 1 434 to ensure that the locking slot 2 432 and the corresponding plug 2 532 are always aligned. Thus, when the clamping head 1 424 and the clamping head 2 513 clamp optical lenses of different diameters, the plug 2 532 can always stably lock and reinforce the U-shaped frame 423 and the clamping head 1 424.
[0059] The above-described operation method enables the support mechanism 3 and the clamping mechanism 4 to be integrated and reinforced into a whole after they have completed the support, positioning and clamping of the optical lens, forming a synergistic and enhanced stable lock. This effectively improves the rigidity and anti-disturbance capability of the lens clamping lock, avoids micro-displacement caused by external force or vibration during the polishing process, and significantly improves the accuracy of surface shape control and the stability of the polishing process. At the same time, the locking mechanism 5 and the clamping mechanism 4 can be matched and adjusted according to the diameter of different lenses to enhance the flexibility and adaptability to various lenses.
[0060] It should be noted that existing technologies can also modify the adaptive support component in the support mechanism 3 into three specific shapes of non-adjustable support structures, such as support structures that adapt to the concave, convex, or flat surfaces of specific optical lenses. These structures can also be adjusted by rotation to meet the support requirements of the lower surface of a specific type of optical lens. However, this only solves the support needs of a single or limited number of optical lenses, and does not adapt to the support needs of optical lenses with various surface shapes, curvatures, and diameters. When polishing other types of optical lenses not covered by the aforementioned support structure, it is still necessary to repurchase or customize the corresponding support structure, thereby increasing costs and non-processing time. In contrast, the present invention not only solves the support needs of various different surface shapes, but also... This invention addresses the support requirements of optical lenses with varying shapes, curvatures, and diameters without increasing procurement or customization costs, while significantly reducing non-processing time. Compared to existing support devices, this solution, although adding adaptive support components to accommodate different surface shapes and curvatures, consists of conventional mechanical structural parts without any high-cost precision components. A one-time investment is sufficient for long-term use, thus the cost of adding these structures is low. Compared to the increased costs associated with purchasing or customizing new support structures and the reduced production efficiency due to longer non-processing time, the cost of adding these structures is negligible. In summary, the above-mentioned technical solution of this invention is a specific improvement based entirely on the existing technology and aimed at solving the technical problems.
