Description

Technical Field

[0001] This invention relates to the field of optical lens processing technology, and in particular to an optical lens processing and grinding equipment. Background Technology

[0002] Optical lens grinding utilizes the synergistic effects of mechanical grinding, chemical hydrolysis, and thermal surface flow, combined with a physical-chemical composite processing of diamond abrasives and polishing fluids such as cerium oxide, to gradually eliminate micron-level unevenness and nano-level damage on the lens surface. This ultimately achieves a high-cleanliness optical surface with a surface roughness Ra ≤ 0.5 nm and an aperture accuracy N ≤ 3. Its core significance lies in ensuring precise optical power and low scattering characteristics by precisely controlling the radius of curvature and eliminating subsurface cracks, thus providing fundamental components for precision optical systems such as high-resolution imaging and laser transmission.

[0003] In the process of optical lens processing, it is necessary not only to ensure the flatness of the upper and lower end faces, but also to ensure that the sidewalls of the lens are smooth without burrs or chipping. Therefore, it is necessary to have the processing capability of both double-sided flat grinding and sidewall fine grinding. Traditional optical lens grinding equipment has a single function and can mostly only achieve simple flat grinding processing. It cannot take the grinding of the lens sidewalls at the same time. It requires separate equipment and separate processes for processing, which is cumbersome and has low processing efficiency. Summary of the Invention

[0031] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] Reference Figure 1-6This invention provides an optical lens processing and grinding apparatus, including a grinding machine table 1 and an upper grinding device. The grinding machine table 1 has a grinding table surface 2 on its top, a limiting toothed ring 21 in the grinding table surface 2, a lower grinding plate 22 in the limiting toothed ring 21, a rotating table 23 in the middle of the lower grinding plate 22, an inner toothed ring 24 on the rotating table 23, and multiple grinding placement pieces 3 installed between the inner toothed ring 24 and the limiting toothed ring 21. The outer wall of each grinding placement piece 3 meshes with the limiting toothed ring 21 and the inner toothed ring 24. Each grinding placement piece 3 has a first mounting groove 31, in which multiple mounting brackets 32 are provided. Each mounting bracket 32 ​​is rotatably connected to a grinding ring 33. A gear 34 is installed in the middle of the first mounting groove 31. A fourth mounting groove 37 is provided in the middle of the grinding placement piece 3, in which a bearing 38 is installed. The bearing 38 is connected to the gear 34. The top is provided with a connecting groove 35. The outer wall of the grinding ring 33 meshes with the gear 34. The grinding ring 33 is provided with a grinding groove 36 for the optical lens to contact the lower grinding plate 22. The outer wall of the rotating table 23 is provided with limiting grooves 231. The grinding machine table 1 is provided with a control panel 5. The upper grinding device 4 includes a support frame 41. A cylinder 42 is installed on the top of the support frame 41. The output end of the cylinder 42 is rotatably connected to the upper grinding frame 43. An upper grinding plate 44 is installed at the bottom of the upper grinding frame 43. The grinding area of ​​the upper grinding plate 44 is corresponding to the grinding area of ​​the lower grinding plate 22. A driving component 45 is installed on the upper grinding frame 43 to drive the gear 34 to rotate. A fixing component 46 for fixing the optical lens is also installed on the upper grinding frame 43. The middle of the upper grinding plate 44 is provided with a through hole 47 that matches the rotating table 23. The inner wall of the through hole 47 is provided with a locking block 471 that matches the limiting groove 231.

[0033] Specifically, under normal double-sided grinding conditions, the operator first places the grinding placement piece 3 on the lower grinding plate 22, engaging it with the limiting gear ring 21 and the internal gear 34. Simultaneously, it needs to be placed in a corresponding manner with the limiting grooves 231 on the rotating table 23 for subsequent positioning. Then, the optical lens to be ground is smoothly placed into the grinding groove 36 inside the grinding ring 33. The lens's orientation is adjusted so that the complete bottom surface of the lens is tightly fitted against the grinding working surface of the lower grinding plate 22, ensuring uniform contact between the bottom of the lens and the grinding reference surface. After loading the lens, the cylinder 42 at the top of the support frame 41 is activated. The output end of the cylinder 42 extends downward, pushing the upper grinding frame 43 vertically downward, simultaneously causing the lower upper grinding plate 44 to slowly adhere to the grinding table 2. During the downward pressing and fitting process of the upper grinding plate 44, the locking block 471 on the inner wall of the through-hole 47 in the middle of the plate will precisely engage with the rotating table. Inside the limiting groove 231 corresponding to the outer wall of the rotating table 23, the locking block 471 engages with the limiting groove 231, and the rotating table 23 rotates to allow the upper and lower grinding plates to grind in opposite directions. At the same time, the internal gear 34 drives the grinding placement piece 3 to rotate and grind. When the equipment is in the process of grinding, the various driving components in the grinding machine table 1 are started to start the lower grinding plate 22. This is for normal double-sided grinding. After the double-sided grinding is completed, when the side wall of the lens needs to be ground, the driving component 45 is connected to the connecting groove 35 on the gear 34. Then, the limiting gear ring 21 and the rotating table 23 are used to fix the grinding placement piece 3. The optical lens is then fixed by the fixing component 46 of the upper grinding device 4. The driving component 45 is then started to rotate the gear 34 to drive the grinding ring 33 on the mounting frame 32 to rotate, so that the side wall of the optical lens can be ground.

[0034] Reference Figure 7-10 According to some embodiments of the present invention, optionally, the drive assembly 45 includes a sliding plate 451, a first motor 452 corresponding to the gear 34 is mounted on the top of the sliding plate 451, a connecting rod 453 matching the connecting groove 35 is mounted on the bottom of the first motor 452, the upper grinding plate 44 is provided with a first through hole 458 for the connecting rod 453 to pass through, lead screws 454 are provided on both sides of the sliding plate 451, the lead screws 454 are connected to a second motor 455, the second motor 455 is mounted on the top of the upper grinding frame 43, the sliding plate 451 is also connected to a limiting rod 456, the limiting rod 456 is installed between the upper grinding plate 44 and the upper grinding frame 43, and the top of the upper grinding frame 43 is provided with a sliding opening 457 for the first motor 452 to move up and down.

[0035] Specifically, when sidewall grinding is required, the grinding placement piece 3 needs to be placed in accordance with the limiting groove 231, and then locked using the limiting gear ring 21 and the inner gear ring 24. Then, the upper grinding device 4 is lowered using a cylinder, so that the upper grinding plate 44 fits against the grinding placement piece 3. Then, the second motor 455 is started to drive the lead screw 454 to rotate. The lead screw 454 drives the sliding plate 451 to slide down steadily and vertically along the limiting rod 456, driving the first motor 452 and the connecting rod 453 to move down as a whole, so that the connecting rod 453 passes through the first through hole 458 of the upper grinding plate 44 and is precisely inserted into the connecting groove 35 at the top of the gear 34, completing the precise power docking. After docking, the first motor 452 is started to independently drive the gear 34 to rotate at high speed, thereby driving the grinding ring 33 to rotate to complete the grinding of the lens sidewall. In the double-sided grinding condition, the sliding plate 451 can be controlled to move upward, so that the connecting rod 453 is completely disengaged from the gear 34, completing the grinding.

[0036] Reference Figure 7-10 According to some embodiments of the present invention, optionally, the fixing component 46 includes a fixing rod 461, the fixing rod 461 being positioned corresponding to the grinding ring 33, the upper grinding plate 44 having a second through hole 462 for the fixing rod 461 to pass through, and a flexible pad 463 being installed at the bottom of the fixing rod 461.

[0037] Specifically, during the sidewall grinding operation, the fixing rod 461 extends downward and passes through the second through hole 462 to press the bottom flexible pad 463 against the upper surface of the optical lens, thereby vertically limiting and fixing the lens to prevent it from jumping, shifting, slipping, or flipping during the double-sided grinding revolution and sidewall rotation fine grinding process, ensuring that the lens processing posture remains stable. At the same time, the flexible pad 463 flexibly contacts the lens, which can avoid hard clamping and damaging the optical surface of the lens.

[0038] Reference Figure 7-10 According to some embodiments of the present invention, optionally, the bottom of the connecting rod 453 is provided with an abrasive pad 459 that matches the first through hole 458, the outer wall of the connecting rod 453 is provided with an annular groove 4531, a plurality of first magnets 4532 are installed in the annular groove 4531, the S pole and N pole of the first magnets 4532 are installed alternately, and a plurality of second magnets 351 are installed in the connecting groove 35, the S and N poles of the second magnets 351 correspond to the N pole and S pole of the first magnets 4532, respectively.

[0039] Specifically, when the connecting rod 453 descends and engages with the gear 34 for sidewall grinding, the first magnet 4532, which is alternately arranged on the outer wall of the connecting rod 453, attracts the opposite poles of the second magnet 351 inside the connecting groove 35, thereby achieving automatic magnetic centering and alignment. This automatically corrects the assembly deviation between the connecting rod 453 and the connecting groove 35, eliminates the docking gap, ensures high coaxiality of the power transmission, and eliminates eccentricity and wobbling during rotation, making the sidewall grinding more uniform and stable. Furthermore, a grinding pad 459 is set at the bottom of the connecting rod 453, which can be used to cover the first through hole 458 for grinding when sidewall grinding is not being used.

[0040] Reference Figure 7-10 According to some embodiments of the present invention, optionally, the mounting bracket 32 ​​is ring-shaped, the top of the mounting bracket 32 ​​is provided with a plurality of rolling grooves 321, a plurality of rolling balls 322 are installed in the rolling grooves 321, and the bottom of the grinding ring 33 is provided with a second mounting groove 323 that matches the mounting bracket 32.

[0041] Specifically, during the sidewall grinding process, the grinding ring 33 rotates continuously at high speed. The second mounting groove 323 at the bottom of the grinding ring 33 is fastened to the annular mounting bracket 32. A rolling support structure is formed by the top rolling ball 322, which changes the traditional sliding friction to rolling friction, greatly reducing the rotational resistance of the grinding ring 33 and making the grinding ring 33 rotate more smoothly and stably.

[0042] Reference Figure 7-10 According to some embodiments of the present invention, optionally, the top of the upper grinding frame 43 is provided with a water tank 431, the bottom of the water tank 431 is connected to the water outlet 433 provided on the upper grinding plate 44 through multiple water pipes 432, and water is introduced from above the water tank 431 through the water inlet pipe 434 provided on the support frame 41.

[0043] Specifically, external cooling water is fed into the water tank 431 through the water inlet pipe 434 of the support frame 41, and then evenly distributed to the water outlet 433 of the upper grinding plate 44 by multiple water pipes 432. This sprays the grinding area at multiple points to cool it down, promptly removing the high temperature generated by the double-sided grinding and high-speed grinding of the side wall, preventing thermal deformation of the lens, and continuously flushing away the fine debris generated during grinding to ensure the cleanliness of the grinding surface.

[0044] Reference Figure 7-10 According to some embodiments of the present invention, optionally, the upper grinding frame 43 is provided with a plurality of protective housings 48 on its top, the second motor 455 is installed in the protective housing 48, and the remaining protective housings 48 are provided with batteries 481, the batteries 481 supply power to all motors on the upper grinding frame 43, the outer wall of the support frame 41 is provided with a switch door 411, and the top of the protective housing 48 is provided with a connecting plate 49, the connecting plate 49 being rotatably connected to the cylinder 42.

[0045] Specifically, the protective casing 48 provides enclosed protection for the second motor 455 and the battery 481, effectively isolating them from grinding moisture, dust, and debris, preventing electrical components from being damaged by moisture, and ensuring long-term stable operation of the equipment. The battery 481 centrally supplies power to the entire motor, with simple wiring and stable operation. The cylinder 42 rotates and cooperates with the upper grinding frame 43 through the connecting plate 49, allowing for appropriate positioning and fine-tuning to ensure precise engagement of the locking block 471 and the limiting groove 231. The switch door 411 on the outside of the support frame 41 facilitates later maintenance and charging of the battery 481.

[0046] Reference Figure 3-5 According to some embodiments of the present invention, optionally, the top of the grinding groove 36 is provided with a plurality of slots 361, in which a detachable grinding sleeve 362 is installed, and the bottom of the grinding sleeve 362 is attached to the lower grinding plate 22 to cover the entire grinding groove 36.

[0047] Specifically, staff can quickly install and replace different specifications of grinding sleeves 362 through slot 361 according to the lens size, double-sided grinding precision, and side wall grinding roughness requirements. This adapts to different product processing needs and is highly versatile. The grinding sleeve 362 completely covers the grinding groove 36, ensuring uniform support at the bottom of the lens and avoiding local suspension that could lead to grinding deviations.

[0048] Reference Figure 5 According to some embodiments of the present invention, optionally, the inner wall of the grinding sleeve 362 is provided with a plurality of placement grooves 363, a first spring 364 is provided in the placement groove 363, the first spring 364 is connected to a grinding block 365, the grinding block 365 is vertically arranged along the grinding sleeve 362 and the contact surface is arc-shaped, and the bottom surface of the grinding placement piece 3 is covered with a drainage groove 366.

[0049] Specifically, during the lens sidewall grinding process, the first spring 364 continuously pushes the arc-shaped grinding block 365 to adaptively fit the arc-shaped sidewall of the lens, which can perform flexible fine finishing on the lens edge, remove chipped edges and burrs, and improve the smoothness of the side. At the same time, it allows water and grinding debris to flow away along the edge. In conjunction with the drainage groove 366 at the bottom of the grinding placement plate 3, grinding wastewater and grinding debris can be quickly discharged to prevent impurities from accumulating and scratching the lens surface.

[0050] Reference Figure 10 According to some embodiments of the present invention, optionally, the top of the fixing rod 461 is provided with a third mounting groove 464, the third mounting groove 464 is provided with a second spring 465, the bottom of the second spring 465 is provided with a push rod 466, and the push rod 466 is connected to the flexible pad 463.

[0051] Specifically, during the double-sided grinding and sidewall grinding processes, the second spring 465 can adaptively extend and retract, and the downward pressure is buffered by the push rod 466. It automatically adapts to the thickness error of the lens and achieves flexible and stable clamping. This ensures that the lens is firmly fixed and does not loosen, while avoiding the lens chipping and breaking caused by rigid pressure, thus greatly improving the processing yield.

[0052] This equipment operates in two modes: double-sided planar grinding and lens sidewall fine grinding. When performing double-sided grinding, firstly, the grinding placement piece 3 is assembled above the lower grinding plate 22, so that the inner and outer sides of the grinding placement piece 3 are engaged with the limiting toothed ring 21 and the inner toothed ring 24 respectively, and are aligned with the limiting groove 231 of the rotating table 23 to complete the pre-positioning of the work station. Then, the optical lens is placed in the grinding groove 36, so that the bottom surface of the lens is in contact with the lower grinding plate 22. The cylinder 42 is started to drive the upper grinding frame 43 to move down, the upper grinding plate 44 is in contact with the grinding table surface 2, and the locking block 471 is locked into the limiting groove 231 to complete the locking and positioning. After the equipment is started, the lower grinding plate 22 and the upper grinding plate 44 rotate in opposite directions. Together with the inner toothed ring 24 and the limiting toothed ring 21, they drive the grinding placement piece 3 to rotate as a whole, ensuring that the upper and lower surfaces of the lens are evenly ground, completing double-sided planar grinding. When fine grinding of the sidewalls is required after double-sided grinding, the lens does not need to be removed. The grinding placement piece 3 is locked and fixed by the rotating table 23 and the limiting toothed ring 21. The lens is vertically stabilized and fixed by the fixing component 46. Then, the second motor 455 drives the lead screw 454 downwards, causing the connecting rod 453 to be magnetically... The gear 34 is connected to the groove 35 to complete the power connection. The first motor 452 is started to drive the gear 34 to rotate independently, which drives the grinding ring 33 to rotate autonomously. The arc-shaped grinding block 365 on the inner side of the grinding sleeve 362 is used to perform a circumferential fine grinding on the side wall of the lens to remove edge burrs and chipping. The entire process can be cooled and chipped by spraying cooling water through the water tank 431. The bottom drainage channel 366 guides the flow and discharges the slag. The flexible and elastic clamping structure stabilizes the lens throughout the process, and finally realizes the integrated automatic processing of double-sided grinding and side wall fine grinding of circular planar optical lenses.
