Description
Technical Field
[0001] This invention relates to the field of optical lens processing technology, specifically to a lens core extraction machine and its working method for optical lens processing. Background Technology
[0002] With the rapid development of optoelectronic technology, optical lenses are increasingly widely used in consumer electronics, medical devices, industrial inspection, aerospace and other fields. These applications place increasingly higher demands on the processing precision and imaging quality of optical lenses. In the processing of optical lenses, the eccentricity error of the lens (i.e., the geometric center of the lens does not coincide with the optical center) is one of the key factors affecting imaging quality. In order to eliminate or reduce this eccentricity error, the lens must undergo precise centering and edge grinding, a process commonly referred to as "core taking" or "centering".
[0003] In order to achieve the transfer of optical lenses in the core-taking equipment, the process relies on the clamping structure driven by the servo mechanism to transfer the optical lenses between the storage station and the grinding station. Since the optical lenses need to pass through the feeding, positioning, grinding and storage stations in sequence and complete a single processing cycle, the optical lenses need to be transferred back and forth. The transfer stroke is long and consumes a long transfer time, which seriously limits the processing efficiency of optical lenses. Therefore, a core-taking machine for optical lens processing and its working method are proposed. Summary of the Invention

[0018] A method for operating a lens core extraction machine for optical lens processing includes the following steps:
[0019] S1. Lens loading: Optical lenses are fixedly placed on the upper part of the feeding plate in a matrix. During operation, the feeding head is moved to the upper part of the feeding plate by the feeding servo slide. Then, the feeding plate is moved and positioned by the cooperation of the first servo slide and the second servo slide, so that the feeding head is directly above the optical lens to be picked up. Then, the feeding head is moved down by the lifting cylinder. The optical lens is picked up and fixed by the picking suction head at the lower part of the feeding head. Then, the optical lens is moved to the upper part of the lens positioning seat at the feeding position on the servo turntable. After placement, the optical lens is fitted into the lens positioning groove in the middle of the lens positioning seat, and the optical lens loading is completed.
[0020] S2, Lens Transfer and Positioning: After the optical lens is placed, the servo turntable rotates counterclockwise at a fixed angle. During the transfer process, the photoelectric sensor on the side of the docking drive cylinder verifies and detects the transfer of the servo turntable. After the rotation and transfer, the next set of optical lenses is placed by the feeding head seat. This process is repeated to complete the rotation and transfer of the optical lenses. When the optical lens rotates to the picking position, the docking drive cylinder drives the docking end to move up. During the process, the upper end of the docking end contacts and fits with the groove surface of the docking slot at the bottom of the lens positioning seat. After fitting, the docking end and the air hole in the middle of the docking slot are sealed and connected. Then, the micro-motion cylinders on both sides of the lens positioning slot are driven by the connecting air path to work. The optical lens is aligned and centered by the centering guide. The micro-motion cylinder retracts and resets. Then, the docking drive cylinder drives the docking end to move down and reset, completing the positioning of the optical lens.
[0021] S3. Lens Picking: After the optical lens is positioned, the servo rotary table drives the transverse servo slide to rotate 90 degrees counterclockwise. Then, the transverse servo slide drives the double-head suction cup to move horizontally to directly above the positioned optical lens. After that, the displacement drive motor drives the double-head suction cup to rotate 90 degrees to make the transfer head of the double-head suction cup vertical. Then, the lifting drive slide drives the double-head suction cup to move down to complete the picking up of the optical lens.
[0022] S4. Lens Grinding: After the optical lens is picked up, the double-head suction unit moves the optical lens to above the grinding tool holder. Then, the double-head suction unit flips 90 degrees to make the transfer suction head horizontal. After that, the double-head suction unit moves the optical lens down to make the optical lens and the grinding drive head coaxial. Then, the grinding head drive slide drives the two sets of grinding drive heads to approach the double-head suction unit and completes the adsorption limit of the optical lens through the adsorption end. Then, the double-head suction unit moves up to leave the processing area. After completion, the two sets of grinding drive heads continue to approach to clamp and fix the optical lens in the grinding position. Then, the grinding drive head drives the optical lens to rotate on a fixed axis. At the same time, the grinding tool holder drives the grinding tool disc to approach and contact the optical lens to complete the optical lens grinding process.
[0023] S5. Lens Unloading: After grinding, the optical lens is picked up and fed in the same manner as described above. While installing the optical lens, the transfer head on the other side of the double-headed suction cup is used to pick up and limit the processed optical lens. Then, the double-headed suction cup moves up and away from the processing area, placing the processed optical lens on the upper part of the lens positioning seat in an empty position. Then, the servo turntable rotates and changes position again, and the double-headed suction cup completes the picking up of the next set of optical lenses. After that, the processed optical lens follows the servo turntable to rotate and change position. When it reaches the unloading position, the picking head is driven by the picking drive slide to pick up the processed optical lens. Then, the picking head is used to transfer the processed optical lens to the upper part of the storage plate, completing the unloading of the optical lens.
[0024] Compared with the prior art, the present invention, employing the above technical solution, has the following technical effects:
[0025] 1. The core extraction machine adopts a rotary transfer auxiliary structure. A servo turntable is set on the upper part of the processing table, and the feeding and storage areas are set on the side of the servo turntable. During operation, the feeding head is driven by the servo structure to complete the feeding and transportation of optical lenses. Then, the optical lens is transferred to the workstation by the fixed-angle rotation of the servo turntable. This eliminates the need for sequential transfer between multiple transport components, reduces the transfer stroke of the optical lens, and enables the simultaneous operation of multiple transport components, which can further shorten the transfer time of optical lenses and improve the processing efficiency of optical lenses.
[0026] 2. A lens positioning seat is set on the upper part of the servo turntable, and a micro-motion cylinder is installed on the side of the positioning groove in the middle of the lens positioning seat. During the transfer of optical lenses, the centering and pushing of the micro-motion cylinders on both sides of the positioning groove can realize the rapid and accurate positioning of the optical lenses. The structure is simple and the operation is reliable, which is conducive to improving the processing accuracy of optical lenses. In addition, the micro-motion cylinder adopts a split docking type drive method. The micro-motion cylinder relies on the lifting drive of the docking drive cylinder installed below the picking station to realize the docking and connection of the working air circuit. The structure is simple and the operation is reliable, eliminating the need for the layout of pneumatic connection structures such as connecting air pipes and control valve groups, which is conducive to improving the rotational working accuracy of the servo turntable and the overall working stability of the device.
[0027] 3. It adopts a dual-head material handling structure, relying on the dual-head suction base installed under the material handling support to complete the material handling of optical lenses. The dual-head suction base is equipped with dual suction heads, which can simultaneously pick up and limit two sets of optical lenses. The dual-head suction base is driven by a switching drive motor to rotate. Through a 90-degree flip-up switching position, it can quickly switch between vertical and horizontal material handling modes. During operation, it can efficiently complete the material handling and transfer of optical lenses, which is conducive to improving the transfer efficiency of optical lenses.

[0049] A method for operating a lens core extraction machine for optical lens processing includes the following steps:
[0050] S1. Lens loading: Optical lenses are fixedly placed on the upper part of the feeding plate 1 in a matrix. During operation, the feeding head seat 6 is moved to the upper part of the feeding plate 1 by the feeding servo slide 5. Then, the feeding plate 1 is moved and positioned by the cooperation of the first servo slide 3 and the second servo slide 4, so that the feeding head seat 6 is directly above the optical lens to be picked up. Then, the feeding head seat 6 is moved down by the lifting cylinder. The optical lens is picked up and fixed by the picking suction head at the lower part of the feeding head seat 6. Then, the optical lens is moved to the upper part of the lens positioning seat 10 at the feeding position on the servo turntable 9. After placement, the optical lens is fitted and installed in the lens positioning groove in the middle of the lens positioning seat 10, thus completing the optical lens loading work.
[0051] S2, Lens Transfer and Positioning: After the optical lens is placed, the servo turntable 9 rotates counterclockwise at a fixed angle. During the transfer process, the photoelectric sensor 14 on the side of the docking drive cylinder 12 verifies and detects the transfer of the servo turntable 9. After the rotation and transfer, the feed head seat 6 completes the placement of the next set of optical lenses. This process is repeated to complete the rotation and transfer of the optical lenses. When the optical lens rotates to the picking position, the docking drive cylinder 12 drives the docking end 13 to move upward. During this process, the upper end of the docking end 13 contacts and fits against the groove surface of the docking slot 15 at the bottom of the lens positioning seat 10. After fitting, the docking end 13 and the air hole in the middle of the docking slot 15 are sealed and connected. Then, the micro-motion cylinders 11 on both sides of the lens positioning slot are driven by the connecting air path to work. The optical lens is aligned and centered by the centering guide. The micro-motion cylinder 11 retracts and resets. Then, the docking drive cylinder 12 drives the docking end 13 to move downward and reset, completing the positioning of the optical lens.
[0052] S3. Lens Picking: After the optical lens is positioned, the servo rotary table 16 drives the transverse servo slide 18 to rotate 90 degrees counterclockwise. Then, the transverse servo slide 18 drives the double-head suction cup 21 to move horizontally to directly above the positioned optical lens. After that, the position drive motor 20 drives the double-head suction cup 21 to rotate 90 degrees to make the transfer head of the double-head suction cup 21 vertical. Then, the lifting drive slide 17 drives the double-head suction cup 21 to move down to complete the picking up of the optical lens.
[0053] S4. Lens Grinding: After the optical lens is picked up, the double-head suction base 21 moves the optical lens to above the grinding tool holder 24. Then, the double-head suction base 21 flips 90 degrees to make the transfer suction head horizontal. Then, the double-head suction base 21 moves the optical lens down to make the optical lens and the grinding drive head 23 coaxial. Then, the grinding head drive slide 22 drives the two sets of grinding drive heads 23 to approach the double-head suction base 21 and completes the adsorption limit of the optical lens through the adsorption end. Then, the double-head suction base 21 moves up to leave the processing area. After completion, the two sets of grinding drive heads 23 continue to approach to make the optical lens clamped and fixed in the grinding position. Then, the grinding drive head 23 drives the optical lens to rotate on a fixed axis. At the same time, the grinding tool holder 24 drives the grinding tool disc to approach and contact the optical lens to complete the grinding process of the optical lens.
[0054] S5. Lens Unloading: After the grinding process is completed, the optical lens is picked up and fed in the same way as described above. While the optical lens is being installed, the transfer suction head on the other side of the double-head suction base 21 is used to pick up and limit the processed optical lens. Then the double-head suction base 21 moves up and leaves the processing area, and the processed optical lens is placed on the upper part of the lens positioning seat 10 which is in an empty state. Then the servo turntable 9 rotates and changes position again, and the double-head suction base 21 completes the picking up of the next set of optical lenses. After that, the processed optical lens follows the servo turntable 9 to rotate and change position. When it reaches the unloading position, the picking head seat 8 is driven by the picking drive slide 7 to complete the picking up of the processed optical lens. Then the picking head seat 8 is used to transfer the processed optical lens to the upper part of the storage plate 2, and the unloading of the optical lens is completed.
[0055] In summary, the core extraction machine adopts a rotary transfer auxiliary structure. A servo rotary table 9 is set on the upper part of the processing table, and the feeding and storage areas are separated on the side of the servo rotary table 9. During operation, the feeding head seat 6 is driven by the servo structure to complete the feeding and transportation of optical lenses. Then, the optical lenses are transferred to the workstation by the fixed-angle rotation of the servo rotary table 9. This eliminates the need for sequential transfer between multiple transport components, reduces the transfer stroke of the optical lenses, and enables simultaneous operation of multiple transport components, further shortening the transfer time of optical lenses and improving the processing efficiency of optical lenses. A lens positioning seat 10 is set on the upper part of the servo rotary table 9, and a micro-actuator 11 is installed on the side of the positioning groove in the middle of the lens positioning seat 10. During the transfer of optical lenses, the centering and guiding push of the micro-actuator 11 on both sides of the positioning groove can achieve rapid and accurate positioning of the optical lenses. The structure is simple, the operation is reliable, and it is beneficial to... The precision of optical lens processing is improved, and the micro-motion cylinder 11 adopts a split docking drive method. The micro-motion cylinder 11 relies on the lifting drive of the docking drive cylinder 12 installed below the picking station to realize the docking connection of the working air circuit. The structure is simple and reliable, eliminating the need for pneumatic connection structures such as connecting air pipes and control valve groups. This is conducive to improving the rotational working accuracy of the servo turntable 9 and the overall working stability of the device. The dual-head picking working structure relies on the dual-head suction seat 21 installed under the picking support 19 to complete the picking of optical lenses. The dual-head suction seat 21 adopts a dual suction head setting, which can simultaneously pick up and limit two sets of optical lenses. The dual-head suction seat 21 is driven by the switching drive motor 20 to rotate. Through a 90-degree flip-up switching position, the vertical and horizontal picking modes can be quickly switched. During operation, the picking and transfer of optical lenses can be completed efficiently, which is conducive to improving the transfer efficiency of optical lenses.

Lens loading: Optical lenses are fixedly placed on the upper part of the feeding plate (1) in a matrix. During operation, the feeding head seat (6) is driven to move above the feeding plate (1) by the feeding servo slide (5). Then, the feeding plate (1) is moved and positioned by the cooperation of the first servo slide (3) and the second servo slide (4), so that the feeding head seat (6) is directly above the optical lens to be picked up. Then, the feeding head seat (6) is driven to move down by the lifting cylinder. The optical lens is picked up and fixed by the picking suction head at the bottom of the feeding head seat (6). Then, the optical lens is moved to the upper part of the lens positioning seat (10) at the feeding position on the servo turntable (9). After placement, the optical lens is fitted and installed with the lens positioning groove in the middle of the lens positioning seat (10), thus completing the optical lens loading work. S2, Lens Transfer and Positioning: After the optical lenses are placed, the servo turntable (9) rotates counterclockwise at a fixed angle. During the transfer process, the photoelectric sensor (14) on the side of the docking drive cylinder (12) verifies and detects the transfer of the servo turntable (9). After the rotation and transfer, the next set of optical lenses is placed by the feeding head seat (6). The rotation and transfer of optical lenses are completed in this way. When the optical lens rotates to the picking position, the docking drive cylinder (12) drives the docking end (13) to move upward. During the process, the upper end of the docking end (13) contacts and fits against the groove side of the docking slot (15) at the lower part of the lens positioning seat (10). After fitting, the docking end (13) and the air hole in the middle of the docking slot (15) are sealed and connected. Then, the micro-movement cylinders (11) on both sides of the lens positioning slot are driven to work through the connecting air path. The optical lens is aligned and centered by the centering guide. The micro-movement cylinder (11) retracts and resets. Then, the docking drive cylinder (12) drives the docking end (13) to move down and reset, thus completing the positioning work of the optical lens. S3, Lens Picking: After the optical lens is positioned, the servo turntable (16) drives the transverse servo slide (18) to rotate 90 degrees counterclockwise. Then, the transverse servo slide (18) drives the double-head suction cup (21) to move horizontally to directly above the positioned optical lens. Then, the displacement drive motor (20) drives the double-head suction cup (21) to rotate 90 degrees to make the transfer head of the double-head suction cup (21) vertical. Then, the lifting drive slide (17) drives the double-head suction cup (21) to move down to complete the picking up of the optical lens. S4. Lens Grinding: After the optical lens is picked up, the double-head suction base (21) moves the optical lens to the top of the grinding tool holder (24). Then, the double-head suction base (21) flips 90 degrees to make the transfer suction head horizontal. Then, the double-head suction base (21) moves the optical lens down to make the optical lens and the grinding drive head (23) coaxial. Then, the grinding head drive slide (22) drives the two sets of grinding drive heads (23) to approach the double-head suction base (21) and completes the adsorption limit of the optical lens through the adsorption end. Then, the double-head suction base (21) moves up to leave the processing area. After completion, the two sets of grinding drive heads (23) continue to approach to make the optical lens clamped and fixed in the grinding position. Then, the grinding drive head (23) drives the optical lens to rotate on a fixed axis. At the same time, the grinding tool holder (24) drives the grinding tool disk to approach and contact the optical lens to complete the grinding process of the optical lens. S5. Lens unloading: After the grinding process is completed, the optical lens is picked up and fed in the same way as above. While the optical lens is installed, the optical lens is picked up and limited by the transfer suction head on the other side of the double-head suction seat (21). Then the double-head suction seat (21) moves up and leaves the processing area. The optical lens is placed on the upper part of the lens positioning seat (10) which is in an empty state. Then the servo turntable (9) rotates and changes position again. The next set of optical lenses is picked up by the double-head suction seat (21). The optical lens is then rotated and changed position with the servo turntable (9). When it reaches the unloading position, the picking head seat (8) is driven by the picking drive slide (7) to pick up the optical lens. Then the optical lens is transferred to the upper part of the storage plate (2) by the picking head seat (8) to complete the unloading of the optical lens.
