Description

Technical Field

[0001] This invention belongs to the field of optical cold processing technology, specifically a high-precision optical lens processing device. Background Technology

[0002] Optical lenses are core imaging components in optoelectronic products such as cameras, microscopes, telescopes, automotive cameras, and high-end mobile phone camera modules. With the rapid development of consumer electronics, autonomous driving, and machine vision, increasingly higher demands are being placed on the imaging accuracy, surface quality, and production efficiency of optical lenses. In the cold processing of optical lenses, the polishing process is a crucial step that determines the surface smoothness, surface shape accuracy (aperture, astigmatism), and final image quality of the lens.

[0003] Currently, high-precision optical lens polishing generally employs a slurry-assisted mechanochemical polishing process. To achieve continuous production and reduce consumable costs, most existing polishing equipment is equipped with a slurry recycling system, designed to collect, filter, and reuse the used slurry at the polishing interface.

[0004] Traditional polishing slurry circulation systems mostly employ gravity filtration, relying on the liquid's gravity to pass through the filter screen, lacking active driving force. When the solid content in the polishing slurry increases or the filter screen becomes clogged, the filtration flux drops sharply, and insufficient slurry supply severely restricts production cycle time, requiring frequent shutdowns for cleaning. Furthermore, glass shards, abrasive agglomerates, and other particles easily form a dense filter cake on the filter media surface, leading to rapid pore blockage. Interruption of the slurry supply causes the polishing interface to lose lubrication and cooling, resulting in the ablation and carbonization of the polishing tools; simultaneously, the uniformity of the liquid film is disrupted, easily causing scratches, orange peel, and other defects on the lens surface, significantly reducing the yield of finished products. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision optical lens processing apparatus to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-precision optical lens processing apparatus, comprising a processing table, a turntable assembly for mounting optical lenses, and a polishing cover that cooperates with the turntable assembly to polish the optical lenses; A polishing fluid pipe for spraying polishing fluid onto optical lenses is provided on one side of the turntable assembly. The end of the polishing fluid pipe away from the turntable assembly is installed inside the processing table. A circulation pump and a storage tank are provided inside the processing table. The two ends of the circulation pump are connected to the storage tank and the polishing fluid pipe respectively through a liquid supply pipeline. The bottom of the turntable assembly is provided with a filter plate and a filter cylinder for filtering the polishing liquid. An annular cavity for the filter cylinder to rotate is opened in the processing table. A recovery pipe is connected to one side of the bottom of the annular cavity. The end of the recovery pipe away from the annular cavity is connected to a storage tank. A receiving ring is fixedly installed on the top of the filter cylinder, and the receiving ring is located below the filter plate. A second scraper is rotatably installed on the top of the filter plate. The filter cartridge is provided with an inlet and an outlet at the top and bottom, respectively, and a first ball valve is installed in the outlet by means of a control mechanism.

[0007] As a further technical solution of the present invention, the control mechanism includes a dual-axis motor installed inside the filter cartridge, both ends of the dual-axis motor are fixedly connected to a drive shaft, and the outside of one of the drive shafts is connected to a first valve stem through a belt drive mechanism, and the first valve stem is fixedly installed on the outer wall of the first ball valve. A discharge ring is fixedly installed at the bottom of the filter cartridge, and the discharge ring is rotatably installed inside the processing table; A first scraper is rotatably installed inside the filter cartridge.

[0008] As a further technical solution of the present invention, a first ring gear is fixedly installed on the outside of the filter cartridge, a first gear meshes with the inner wall of the first ring gear, a first rotating shaft is fixedly connected inside the first gear, and a motor is installed at the bottom of the first rotating shaft.

[0009] As a further technical solution of the present invention, a second ring gear is fixedly installed on the top of the first scraper, a second gear is meshed on one side of the second ring gear, a second rotating shaft is embedded in the second gear, a third gear is installed on the outer wall of the second rotating shaft, a third ring gear is meshed on the outer wall of the third gear, and the third ring gear is fixedly installed in the processing table.

[0010] As a further technical solution of the present invention, a connecting part is fixedly installed on the outer wall of the second rotating shaft, and the connecting part is slidably installed in the third gear and the second gear; The bottom of the second rotating shaft is provided with a cam, which is fixedly mounted on the outside of the other drive shaft.

[0011] As a further technical solution of the present invention, a second ball valve is rotatably installed in the feed port via a second valve stem, and a movable rod is slidably connected to the outside of the second valve stem, with one end of the movable rod located at the top of the second rotating shaft; A slider is fixedly installed inside the movable rod, and the slider is slidably installed in a slide groove, which is formed on the outer wall of the second valve rod.

[0012] As a further technical solution of the present invention, the second scraper is evenly installed in a ring array inside the rotating ring, and the rotating ring is located at the top of the receiving ring; A first connecting block is fixedly installed on the outer wall of the rotating ring. A connecting rod is installed inside the first connecting block. The bottom of the connecting rod is embedded in a second connecting block. The second connecting block is fixedly installed on the outer wall of the receiving ring. A guide block is provided at the end of the connecting rod away from the first connecting block. The guide block is rotatably installed in the processing table via a fourth rotating shaft. A fourth gear is fixedly installed on the outer wall of the fourth rotating shaft, and the fourth gear meshes with the second connecting block.

[0013] The beneficial effects of this invention are as follows: 1. This invention constructs a two-stage filtration system, from coarse filtration to centrifugal fine filtration, by incorporating a filter plate and a filter cartridge. Polishing waste liquid first passes through the filter plate to intercept large particles, then enters the high-speed rotating filter cartridge. Powerful centrifugal force actively separates micron-sized impurities, completely replacing the inefficient traditional gravity-fed filtration method. This combination significantly improves filtration throughput and liquid supply stability, ensuring that the polishing interface always receives a sufficient amount of clean polishing liquid. This effectively avoids the ablation and carbonization of polishing tools due to interrupted liquid supply and greatly reduces the risk of scratches, orange peel, and pitting on the lens surface, ensuring the yield and processing speed of high-precision optical lenses.

[0014] 2. This invention achieves precise control and active cleaning of the slag discharge process by incorporating a first scraper and a dual-axis motor. When slag discharge is required, the dual-axis motor drives the first ball valve to open the discharge port. Simultaneously, through the linkage of the cam and the magnetic connection, the first scraper rotates only at the moment of discharge, actively peeling off the compacted impurity layer on the inner wall of the filter cartridge and guiding it to the outlet. This solves the problems of impurity bridging and adhesion, ensuring thorough and clean slag discharge. During the high-speed centrifugal separation stage, the first scraper remains stationary, avoiding unnecessary friction and excessive crushing of impurities. This significantly extends the service life of the scraper and filter cartridge and prevents secondary contamination of the polishing liquid by fine particles, thereby ensuring the stability and efficiency of the equipment during long-term continuous operation.

[0017] 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.

[0018] like Figures 1 to 9 As shown in the embodiment of the present invention, a high-precision optical lens processing device includes a processing table 1, a turntable assembly 2 for mounting optical lenses, and a polishing cover 3 that cooperates with the turntable assembly 2 to polish the optical lenses. A polishing liquid pipe 4 for spraying polishing liquid onto optical lenses is provided on one side of the turntable assembly 2. The end of the polishing liquid pipe 4 away from the turntable assembly 2 is installed in the processing table 1. A circulation pump 5 and a storage tank 6 are provided in the processing table 1. The two ends of the circulation pump 5 are connected to the storage tank 6 and the polishing liquid pipe 4 respectively through the liquid supply pipeline. The bottom of the turntable assembly 2 is provided with a filter plate 7 and a filter cylinder 10 for filtering the polishing liquid. The processing table 1 has an annular cavity 8 for the filter cylinder 10 to rotate. A recovery pipe 9 is connected to one side of the bottom of the annular cavity 8. The end of the recovery pipe 9 away from the annular cavity 8 is connected to the liquid storage tank 6. A receiving ring 19 is fixedly installed on the top of the filter cylinder 10. The receiving ring 19 is located below the filter plate 7. A second scraper 35 is rotatably installed on the top of the filter plate 7. The filter cartridge 10 has an inlet and an outlet at the top and bottom, respectively, and a first ball valve 11 is installed in the outlet by means of a control mechanism.

[0019] During processing, the optical lens is first installed on the outer surface of the turntable assembly 2, and then the polishing cover 3 is placed on top of the turntable assembly 2. The polishing mechanism makes the polishing cover 3 rotate on top of the turntable assembly 2 and cooperate with the rotation of the turntable assembly 2 to polish the optical lens. Simultaneously, polishing liquid is drawn from storage tank 6 by circulation pump 5 and sprayed onto the polishing area through polishing liquid pipe 4. The polishing liquid and polished impurities, such as glass fragments, fall into the groove on the platform. After preliminary filtration by filter plate 7, it enters filter cartridge 10. The filter cartridge 10 then rotates at high speed in annular cavity 8, generating strong centrifugal force for solid-liquid separation. After filtration, impurities remain in filter cartridge 10, while polishing liquid enters annular cavity 8 and is recovered to storage tank 6 via recovery pipe 9 for recycling. During centrifugal filtration, the first ball valve 11 can also be opened to discharge impurities.

[0020] The above-mentioned method of coarse filtration through filter plate 7 followed by fine filtration through filter cartridge 10 ensures that the polishing fluid used in circulation has a high degree of cleanliness, thereby significantly reducing the risk of the lens being scratched, developing orange peel or pitting.

[0021] It replaces the traditional, inefficient gravity flow method, achieving active solid-liquid separation. This provides a stable and high-flow-rate liquid supply, meeting the cycle time requirements of continuous polishing operations and fundamentally solving the problem of sharp reduction in filtration flux caused by clogging in traditional solutions.

[0022] The second scraper 35 continuously cleans the surface of the filter plate 7, disrupting the conditions for impurities to form a "filter cake layer", ensuring that the filter plate 7 always maintains high permeability and that the filtration throughput does not decrease due to prolonged operation.

[0023] The inlet and outlet of the storage tank 6 are connected to the annular cavity 8 and the circulating pump 5, respectively.

[0024] To prevent abrasive sedimentation and ensure a constant concentration, an agitation mechanism should also be installed inside the storage tank 6. The agitation mechanism is existing technology and will not be described in detail here.

[0025] The processing table 1 has an annular groove for guiding the liquid, which surrounds the polishing station and forms a closed annular flow channel. It collects the splashed and flowing waste liquid during the polishing process and serves as a guide channel.

[0026] A through hole is provided at the connection between the receiving ring 19 and the feed inlet, so that the polishing liquid inside the receiving ring 19 can enter the filter cartridge 10 through the through hole.

[0027] Multiple filter cartridges 10 can be set up, and the multiple filter cartridges 10 are evenly distributed in a ring array, which can improve the total processing capacity and production cycle.

[0028] The patent application CN120696883B discloses an optical lens processing turntable. This patent discloses the processing table 1, turntable assembly 2, polishing cover 3, polishing mechanism, the rotation method of turntable assembly 2 and the fixing method of optical lenses proposed in this application. These technical means will not be described in detail here.

[0029] like Figure 6 and Figure 7 As shown, the control mechanism includes a dual-axis motor 12 installed inside the filter cartridge 10. Both ends of the dual-axis motor 12 are fixedly connected to a drive shaft 13. The outside of one of the drive shafts 13 is connected to the first valve stem 14 through a belt drive mechanism. The first valve stem 14 is fixedly installed on the outer wall of the first ball valve 11. A discharge ring 26 is fixedly installed at the bottom of the filter cartridge 10, and the discharge ring 26 is rotatably installed inside the processing table 1; A first scraper 20 is rotatably installed inside the filter cartridge 10.

[0030] The processing table 1 has an annular discharge groove for the discharge ring 26 to rotate. A discharge port is connected to one side of the annular discharge groove to facilitate the discharge of impurities.

[0031] When it is necessary to discharge impurities from the filter cartridge 10, the dual-shaft motor 12 drives the transmission shaft 13 to rotate. When the transmission shaft 13 rotates, it drives the first valve stem 14 to rotate through the belt transmission mechanism. When the first valve stem 14 rotates, it drives the first ball valve 11 to rotate 90 degrees, opening the bottom discharge port of the filter cartridge 10, so that the impurities in the filter cartridge 10 can be discharged into the annular discharge trough.

[0032] During discharge, the first scraper 20 inside the filter cylinder 10 rotates, actively peeling off the impurities located on the inner wall of the filter cylinder 10 and guiding them to the discharge port at the bottom, thus solving the problem of incomplete discharge caused by impurity bridging or adhesion, thereby ensuring the high efficiency and stability of the equipment in long-term continuous operation.

[0033] A third scraper is fixedly installed at the bottom of the discharge ring 26. The third scraper slides against the inner wall of the annular discharge trough. The filter cylinder 10 drives the discharge ring 26 to rotate, causing the discharge ring 26 to drive the third scraper to rotate in the annular discharge trough, actively pushing out the impurities in the annular discharge trough and discharging them from the discharge port.

[0034] like Figures 1 to 9 As shown, a first ring gear 15 is fixedly installed on the outside of the filter cartridge 10, a first gear 16 meshes with the inner wall of the first ring gear 15, a first rotating shaft 17 is fixedly connected inside the first gear 16, and a motor 18 is installed at the bottom of the first rotating shaft 17.

[0035] like Figure 2 , Figure 3 and Figure 5As shown, a second ring gear 21 is fixedly installed on the top of the first scraper 20. A second gear 22 meshes with one side of the second ring gear 21. A second rotating shaft 23 is embedded in the second gear 22. A third gear 24 is installed on the outer wall of the second rotating shaft 23. A third ring gear 25 meshes with the outer wall of the third gear 24. The third ring gear 25 is fixedly installed in the processing table 1.

[0036] When the filter cartridge 10 rotates, it drives the third gear 24 to rotate together within the annular cavity 8. The rotation of the third gear 24 meshes with the third ring gear 25 and rotates on its own. When the third gear 24 rotates, it drives the second gear 22 to rotate via the second rotating shaft 23. When the second gear 22 rotates, it drives the second ring gear 21 to rotate. When the second ring gear 21 rotates, it drives the first scraper 20 to rotate within the filter cartridge 10, providing it with power. This eliminates the need for a separate motor 18, reducer, cylinder, and control system for the rotation of the first scraper 20, significantly simplifying the equipment structure.

[0037] Furthermore, the mechanical transmission mechanism is set on the rotation path, and the driving torque provided by the mechanical transmission is relatively constant. It is less affected by fluctuations in working conditions such as the viscosity of the polishing liquid and the thickness of impurity accumulation. This ensures that the scraping force applied by the first scraper 20 at various positions on the inner wall of the filter cartridge 10 is basically consistent, thus ensuring clean slag discharge and no residual dead corners.

[0038] The teeth on the outer wall of the second rotating shaft 23 are intermittently arranged to cause the third gear 24 to rotate intermittently, thereby causing the first scraper 20 to rotate intermittently within the filter cartridge 10. This minimizes the frequency and speed of friction between the first scraper 20 and the filter cartridge 10, thus improving its service life.

[0039] like Figure 7 and Figure 8 As shown, a connecting part 28 is fixedly installed on the outer wall of the second rotating shaft 23, and the connecting part 28 is slidably installed in the third gear 24 and the second gear 22; The bottom of the second rotating shaft 23 is provided with a cam 27, which is fixedly installed on the outside of another drive shaft 13.

[0040] The bottom of the second rotating shaft 23 is elastically connected to the filter cartridge 10 via the first spring; The connecting parts 28 are all slidably and magnetically connected to the interior of the third gear 24 and the second gear 22; When the first ball valve 11 is rotated to open the discharge, the drive shaft 13 rotates, driving the cam 27 to rotate. The rotation of the cam 27 drives the second rotating shaft 23 to move upward, so that the connecting part 28 is embedded in the second gear 22 and the two are magnetically connected. Then, the rotation of the second rotating shaft 23 drives the second gear 22 to rotate, providing power for the rotation of the first scraper 20.

[0041] The first scraper 20 rotates only during material discharge to minimize high-speed friction, improve service life, and prevent the first scraper 20 from repeatedly crushing glass shards and polishing scale fragments already attached to the cylinder wall when the filter cartridge 10 is centrifugally separating the polishing liquid. This could crush these impurities into finer particles, allowing them to penetrate the through holes in the inner wall of the filter cartridge 10 and be remixed into the clean polishing liquid.

[0042] like Figure 6 and Figure 7 As shown, a second ball valve 29 is rotatably installed inside the feed inlet via a second valve stem 30, and a moving rod 31 is slidably connected to the outside of the second valve stem 30, with one end of the moving rod 31 located at the top of the second rotating shaft 23; A slider 32 is fixedly installed inside the moving rod 31. The slider 32 is slidably installed in the slide groove 33, which is formed on the outer wall of the second valve rod 30.

[0043] The movable rod 31 is elastically mounted inside the filter cartridge 10 via a second spring; The slide 33 is set to be arc-shaped; The contact surface between the moving rod 31 and the second rotating shaft 23 is set as an inclined surface; When the first ball valve 11 rotates to open the discharge port, the second rotating shaft 23 moves upward, causing the moving rod 31 to move to one side. The movement of the moving rod 31 causes the slider 32 to slide within the slide groove 33. Guided by the arc shape of the slide groove 33, the second valve rod 30 rotates, thereby causing the second ball valve 29 to rotate and close the feed port of the filter cartridge 10. This prevents new material from entering when impurities are discharged from inside the filter cartridge 10, thus preventing continuously flowing new waste liquid from flowing directly out of the open bottom discharge port without secondary filtration. This ensures the stability and reliability of the high-precision optical lens during continuous processing.

[0044] like Figure 3 , Figure 4 and Figure 5 As shown, the second scraper 35 is evenly installed in a ring array inside the rotating ring 34, and the rotating ring 34 is located on top of the receiving ring 19; A first connecting block 36 is fixedly installed on the outer wall of the rotating ring 34. A connecting rod 38 is installed inside the first connecting block 36. The bottom of the connecting rod 38 is embedded in the second connecting block 37. The second connecting block 37 is fixedly installed on the outer wall of the receiving ring 19. A guide block 39 is provided at the end of the connecting rod 38 away from the first connecting block 36. The guide block 39 is rotatably installed in the processing table 1 via the fourth rotating shaft 40. A fourth gear 41 is fixedly installed on the outer wall of the fourth rotating shaft 40. The fourth gear 41 meshes with the second connecting block 37.

[0045] The connecting rod 38 is elastically connected to the first connecting block 36 via a third spring; The rotating ring 34 is connected to the receiving ring 19 by embedding the connecting rod 38 into the second connecting block 37. When the filter cylinder 10 is rotating, the second scraper 35 rotates on the top of the filter plate 7 for active cleaning.

[0046] The bottom of the connecting rod 38 is arc-shaped, and a connecting groove for the connecting rod 38 to be inserted is opened in the second connecting block 37. The size of the connecting groove is slightly larger than the size of the connecting rod 38, so that the two can be connected better. The top of the guide block 39 is magnetically connected to the connecting rod 38, and the two repel each other when they have the same pole. When the filter cartridge 10 rotates, the receiving ring 19 rotates, and the receiving ring 19 drives the second connecting block 37 to rotate. When the second connecting block 37 rotates to one side of the fourth gear 41, it drives the fourth gear 41 to rotate. When the fourth gear 41 rotates, it drives the guide block 39 to rotate through the fourth rotating shaft 40.

[0047] When the guide block 39 rotates to the bottom of the connecting rod 38, the magnetic drive causes the connecting rod 38 to move upward, disengaging the rotating ring 34 and the receiving ring 19. The second scraper 35 then stops rotating on top of the filter plate 7. When the second connecting block 37 re-engages with the fourth gear 41, the guide block 39 continues to rotate at a certain angle. When the guide block 39 rotates away from the connecting rod 38 and the second connecting block 37 is positioned below the connecting rod 38, the third spring causes the connecting rod 38 to embed into the second connecting block 37, reconnecting the two. The second scraper 35 then rotates on top of the filter plate 7 again. This intermittent rotation of the second scraper 35 ensures that the filter plate 7 will not become clogged due to prolonged lack of cleaning, while also avoiding unnecessary wear caused by excessively frequent cleaning.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
