Description

Technical Field

[0001] The present invention relates to the technical field of optical lens polishing, in particular to a polishing device for optical lens processing. Background Art

[0002] The purpose of the optical lens polishing process is to remove the surface damage layer left by the lens fine grinding process and accurately adjust the surface accuracy of the lens to meet the surface roughness, aperture number and local aperture requirements specified in the design drawings, so that the lens surface can form a smooth, transparent, and defect-free optical working surface; for most optical lenses, both sides of the surface need to be polished with high precision to ensure that the light has good transmission performance and wavefront quality when passing through the lens, thereby ensuring that the final image is clear and stable, to meet the core requirements of the optical system for image quality.

[0003] In the prior art, when performing double-sided polishing on an optical lens, the side surface of the lens is generally first fixed by a clamping mechanism, and a supporting device that matches the shape of the lower surface of the lens is used to stably support and limit the lens, and then the upper polishing equipment is used to polish the locked upper surface of the lens; because the two surfaces of the same lens often have different surface shapes, for example, one side is convex and the other side is concave or flat, and even if the surface shape type is the same, the curvature radius often differs, so after completing the polishing of one side, it is usually necessary to replace the supporting device or transfer and fix the lens to another suitable supporting device to match the surface shape of the other surface of the lens, thereby ensuring that the lens obtains stable support and precise surface shape control during the polishing process, and further ensuring that the final polishing quality meets the optical design requirements.

[0004] However, the traditional double-sided polishing method of the optical lens has the following problems: 1. In the prior art, the support structure used for lens polishing can only match the surface shape and curvature of a specific lens, and there is a lack of a support device that can adapt to different surface shapes. Therefore, when polishing the first surface and processing the other surface, the operator must replace the current support device or disassemble and transfer the lens to another adapted support device. The above replacement or transfer process not only increases the proportion of non-processing time, resulting in complicated process connection, reduced overall efficiency, and decreased economic benefits, but also introduces positioning errors due to frequent disassembly and assembly, affecting the consistency of surface shape control, thereby adversely affecting polishing precision and production rhythm; 2. In the prior art, the support device is usually specially designed for the surface shape and diameter size of a specific lens, resulting in poor universality and difficulty in flexible adaptation to lenses of different diameters or surface shape specifications. Therefore, when switching between different types of lenses for polishing, it is often necessary to re-manufacture or purchase corresponding special support devices, which not only increases the cost of equipment procurement and customization, but also brings additional storage and management burden. Frequent tool replacement also reduces the overall flexibility of the production line, especially in high-mix and small-batch production scenarios, limiting overall processing efficiency and economy.

[0034] See also Figure 1 and Figure 2The adjusting fitting part 31 comprises an electric push rod I 311 fixedly arranged on the lower side of the clamping table 2, the telescopic end of the electric push rod I 311 is fixedly arranged with a lifting table 312 located above the clamping table 2, the lower side of the lifting table 312 is fixedly arranged with a plurality of guide rods I in sliding connection with the clamping table 2, the upper side of the lifting table 312 is fixedly arranged with a support I in symmetry front and back, the opposite sides of the support I are fixedly arranged with rotary air cylinders I 313, and the driving ends of the front and back rotary air cylinders I 313 are fixedly arranged with a rotary table 314 located between the supports I.

[0035] The lifting table 312 and the rotary table 314 can be driven by the electric push rod I 311 to move up and down for adjustment, and the rotary table 314 can be driven by the rotary air cylinder I 313 to rotate at a fixed angle for adjustment.

[0036] Please refer to Figure 2 , Figure 3 and Figure 4 , the butt joint supporting part 32 comprises three mounting grooves 321 uniformly opened in the circumferential direction on the rotary table 314, and the mounting grooves 321 are all mounted with supporting tables 322 through bolts, and the upper supporting table 322 is taken as an example, the left and right sides of the upper supporting table 322 are both provided with locking insertion grooves I 323, and the left and right locking insertion grooves I 323 are distributed in up and down staggered manner, wherein the right locking insertion groove I 323 is located on the upper side, and the left locking insertion groove I 323 is located on the lower side.

[0037] When the optical lens with the plane on the lower side is to be supported, the rotary table 314 can be driven by the rotary air cylinder I 313 to rotate at a fixed angle for adjustment, until the right supporting table 322 is rotated to the upper side, so that the supporting table 322 is away from the flat surface on one side of the corresponding mounting groove 321 to support the lower side surface of the optical lens.

[0038] Please refer to Figure 1 , Figure 3 and Figure 4 , the butt joint fitting part 33 comprises a receiving groove 331 opened on the side away from the corresponding mounting groove 321 of the upper and left supporting tables 322, the receiving groove 331 of the upper supporting table 322 is internally mounted with a supporting ring 332 through a bolt, different supporting rings 332 with different inner diameters are replaced to adapt to optical lenses with different diameters, the receiving groove 331 of the upper supporting table 322 is provided with an adjusting groove 333 on the lower side, a plurality of telescopic grooves 334 are uniformly opened on the lower side of the adjusting groove 333, a supporting column 335 which moves up and down and has a hemispherical upper end is elastically and slidingly arranged in the telescopic groove 334 through a spring, wherein the upper supporting column 335 is longer than the left supporting column 335, and the hemispherical end of the supporting column 335 in the upper supporting table 322 is located on the upper side of the corresponding receiving groove 331, and the hemispherical end of the supporting column 335 in the left supporting table 322 is located on the inner side of the corresponding receiving groove 331.

[0039] When the optical lens with concave lower surface is to be supported and positioned, the existing feeding device is used to place the optical lens with concave lower surface on the upper supporting table 322, and the lower concave surface of the optical lens is in contact with the hemispherical end of the supporting column 335 extending into the corresponding supporting groove 331, and the supporting column 335 is compressed downward, and under the elastic force of the spring, the supporting column 335 is stably attached to the lower concave surface of the optical lens, until the outer edge of the lower surface of the optical lens is in contact with and closely attached to the upper surface of the supporting ring 332, at which time the clamping mechanism 4 can be used to stably clamp and position the side surface of the optical lens, so as to stably clamp and lock the optical lens and keep it concentric with the corresponding supporting groove 331 and the supporting ring 332, then the supporting table 322 and the supporting columns 335 compressed by the lens are synchronously and stably locked by the locking mechanism 5, so that they cannot move up and down, and at the same time the clamping mechanism 4 is also synchronously locked by the locking mechanism 5, thereby realizing stable clamping and locking of the optical lens and uniform and stable support of the lower concave surface of the optical lens.

[0040] When the optical lens with convex lower surface is to be supported and positioned, the rotating table 314 is adjusted by the rotating cylinder 313 to rotate at a certain angle, until the left supporting table 322 is rotated to the upper side, and then the existing feeding device is used to place the optical lens with convex lower surface on the supporting table 322, and the lower convex surface of the optical lens is in contact with the hemispherical end of the supporting column 335 inside the corresponding supporting groove 331, and the supporting column 335 is compressed downward, and under the elastic force of the spring, the supporting column 335 is stably attached to the lower convex surface of the optical lens, until the outer edge of the lower surface of the optical lens is in contact with and closely attached to the upper surface of the supporting ring 332, at which time the clamping mechanism 4 can be used to stably clamp and position the side surface of the optical lens, so as to stably clamp and lock the optical lens and keep it concentric with the corresponding supporting groove 331 and the supporting ring 332, then the supporting table 322 and the supporting columns 335 compressed by the lens are synchronously and stably locked by the locking mechanism 5, so that they cannot move up and down, and at the same time the clamping mechanism 4 is also synchronously locked by the locking mechanism 5, thereby realizing stable clamping and locking of the optical lens and uniform and stable support of the lower convex surface of the optical lens; the supporting column 335 on the supporting table 322 is shorter, which can effectively reduce the deformation of the spring when the convex surface of the lens drives the supporting column 335 to compress the spring, thereby effectively reducing the reaction force of the spring while ensuring the stable attachment of the supporting column 335 to the convex surface of the lens, to ensure the relative stability of the optical lens during placement.

[0041] When the surface on the other side of the optical lens is to be polished, the locking mechanism 5 is first used to release the locking of the clamping mechanism 4 and the corresponding support table 322, and then the electric push rod one 311 is used to drive the lifting table 312 and the rotating table 314 to move downward to make room, and then the clamping mechanism 4 is used to drive the optical lens to flip by 180 degrees, and at the same time the rotating cylinder one 313 is used to drive the rotating table 314 to rotate at a fixed angle for adjustment, until the support table 322 that is adapted to the shape of the polished surface of the optical lens is rotated to the upper side, and then the electric push rod one 311 is used to drive the rotating table 314 to move upward to reset, until the upper surface of the support ring 332 is in contact with and closely fitted with the outer edge of the lower polished surface of the optical lens, and finally the locking mechanism 5 is used to again synchronously lock the corresponding support table 322, the supporting column 335 and the clamping mechanism 4, so that the polishing equipment 1 can stably polish the surface on the other side of the optical lens.

[0042] The above operation mode can flexibly adapt to optical lenses of different diameters, surface shapes and radii of curvature, so as to accurately and stably support various types of optical lenses, thereby completing the support adaptation required for double-sided polishing of various lenses by a single device, without the need to frequently replace the support device or re-clamp the lens due to differences in lens surface shape or size, significantly reducing non-processing and production interruption time, greatly improving polishing efficiency, ensuring surface shape control consistency, and reducing positioning errors caused by disassembly. At the same time, due to the good universality and self-adaptive adjustment capability of the support mechanism 3 of the present application, when switching between different types of lenses for polishing, there is no need to re-purchase or customize special support components, which not only saves equipment purchase and storage management costs, but also enhances the flexibility and economy of the production line in response to multiple varieties and small batch orders.

The upper and lower distributed locking plates 341 are moved relative to each other, and the corresponding end of the straight locking slot 342 is moved to the corresponding support column 335, until the two corresponding straight locking slots 342 are tightly fitted with the side surface of the support column 335 through the corresponding end, so as to stably clamp and lock the corresponding support column 335, so that it cannot move up and down, and then the corresponding supporting table 322 and each support column 335 are synchronously and stably locked. After the top rod 523 is reset and separated from the corresponding locking plate 341, the spring rod drives the corresponding locking plate 341 to move synchronously and reset.

[0056] The rotating adjusting screw rod two 521 can drive the corresponding plug-in bolt one 522 and the top rod 523 to move left and right for adjustment through the screw transmission of the adjusting screw rod two 521 and the corresponding support three, so that the plug-in bolt one 522 and the top rod 523 can be stably locked and reinforced on the supporting table 322 and the support column 335 when the clamping head two 513 and the clamping head one 424 clamp different diameter optical lenses.

[0057] Please refer to Figure 6 and Figure 9 , the clamping and locking part 53 includes a support four symmetrically fixed on the U-shaped frame 512, and an adjusting screw rod three 531 is threadedly connected to the support four. The side of the adjusting screw rod three 531 away from the corresponding electric push rod three 511 is fixedly provided with a plug-in bolt two 532 which is inserted and locked in cooperation with the corresponding locking slot two 432.

[0058] When the electric push rod three 511 drives the corresponding clamping head two 513 to clamp and reinforce the optical lens, the U-shaped frame 512 drives the adjusting screw three 531 to move synchronously through the support four, and the adjusting screw three 531 drives the plug two 532 to dock and insert into the corresponding locking slot two 432 on the corresponding docking slide post 431, thereby stably locking the corresponding docking slide post 431 and the clamping head one 424 on the return frame 423; wherein the rotating adjusting screw three 531 can drive the corresponding plug two 532 to move left and right through the adjusting screw three 531 and the corresponding support four spiral transmission, and simultaneously drive the docking slide post 431 to move back and forth through the adjusting screw one 434 to ensure that the locking slot two 432 and the corresponding plug two 532 are always aligned, so that when the clamping head one 424 and the clamping head two 513 cooperate to clamp optical lenses of different diameters, it can ensure that the plug two 532 always stably locks and reinforces the return frame 423 and the clamping head one 424.

[0059] The above-mentioned operation method can achieve that after the supporting mechanism 3 and the clamping mechanism 4 complete the supporting positioning and clamping fixation of the optical lens respectively, the two can be further integrated and reinforced into a whole to form a synergistically enhanced stable lock, thereby effectively improving the rigidity and anti-disturbance ability of the lens clamping lock, avoiding micro-displacement caused by external force or vibration during the polishing process, and significantly improving 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 flexible adaptability to various lenses.

[0060] It should be noted that the prior art can also change the adaptive supporting component in the supporting mechanism 3 into three specific shapes that cannot be adjusted, such as supporting structures corresponding to the concave, convex or flat surfaces of specific optical lenses, and also adjust the support requirements of the lower surface of a specific type of optical lens by rotation. However, it only solves the support requirements of a single or a small number of types of optical lenses, but does not adapt to the support requirements of a variety of optical lenses with different surface shapes, curvatures and diameters. When replacing other types of optical lenses not covered by the above-mentioned supporting structure for polishing, it is still necessary to re-purchase or customize the corresponding supporting structure, which will also increase the corresponding cost and non-processing time; however, in the solution of the present invention, not only the support requirements of a variety of different surfaces are solved, but also the support requirements of the lower surface of the optical lens are also adjusted. The support requirements of optical lenses with different shapes, curvatures and diameters are met without increasing procurement and customization costs, while significantly reducing non-processing time. Compared with the supporting device in the prior art, although this solution adds adaptive supporting components that adapt to different surface shapes and curvatures, they are all conventional ordinary mechanical structural components, and there are no high-cost precision parts. Only one investment is required for long-term use. Therefore, the cost of adding the above structure is low. Compared with the increased cost caused by purchasing or customizing a new supporting structure and the reduced production efficiency caused by the long non-processing time, the cost of adding the above structure is negligible. In summary, the above technical solution of the present invention is a specific improvement based entirely on the above existing technical conditions and solving technical problems.
