[0025] In the manufacturing process of lenses, polishing is a crucial process that can significantly improve the surface accuracy, overall quality and optical performance of the lens. Ion beam polishing is an advanced non-contact polishing technology. Its working principle is to bombard the surface of the optical lens with a high-energy ion beam emitted by an ion source in a vacuum environment, and use the physical sputtering effect to achieve atomic-level material removal. This technology is known for its high precision, high certainty, excellent surface quality and wide range of applications.
[0026] However, during the ion source polishing process, the surface to be polished is firstly inspected in detail to determine the optimal ion source parameters and polishing path, and then the entire system is evacuated to ensure that the ion beam can perform polishing in an interference-free environment. After the first polishing, the system needs to be re-inflated, the lens is disassembled and flipped, and after the flipping is completed, the surface needs to be inspected again, vacuumed again, and the second polishing operation is performed. This series of operations is not only time-consuming, but also places extremely high demands on the operator's technical level and patience. Each step needs to be precisely controlled to ensure the final polishing result.
[0027] To this end, an ion beam polishing device, referring to Figure 1 to Figure 4 , which includes a vacuum box 1, a first polishing mechanism 2, a second polishing mechanism 3 and a clamping mechanism 4, wherein an installation space is provided in the vacuum box 1, wherein the first polishing mechanism 2 is arranged at the upper part of the installation space, wherein the second polishing mechanism 3 is arranged at the lower part of the installation space, wherein the second polishing mechanism 3 is arranged symmetrically with the first polishing mechanism 2, wherein the clamping mechanism 4 includes a clamping assembly 401 and a fixing assembly 402, wherein the fixing assembly 402 is arranged on the inner bottom surface of the vacuum box 1, wherein the clamping assembly 401 includes two lifting sleeves 403, two telescopic rods 404 and two clamps 405, wherein the lifting sleeves 403 are slidably connected to the fixing assembly 402 so that the lifting sleeves 403 are adjusted up and down, wherein the fixed ends of the telescopic rods 404 are fixedly connected to the lifting sleeves 403 in a one-to-one correspondence, wherein the movable ends of the telescopic rods 404 are fixedly connected to the clamps 405 in a one-to-one correspondence, and wherein the clamps 405 are used to fix the lens.
[0028] By adopting the symmetrically arranged first polishing mechanism 2 and second polishing mechanism 3, the double-sided polishing operation of the lens can be completed in a vacuum environment, reducing the number of times the lens is flipped and the vacuum is re-drawn, thereby significantly improving the polishing efficiency. The fixing component 402 is designed and installed on the inner bottom surface of the vacuum box 1. The clamping component 401 can effectively clamp and fix the workpiece to be polished, ensuring that the workpiece remains stable during the polishing process, thereby improving the polishing quality and accuracy. The clamping component 401 is combined with the fixing component 402 by a sliding connection, so that the clamping component 401 can move up and down within a certain range, enhancing the convenience and reliability of its operation. Through the coordinated work of the lifting sleeve 403 and the telescopic rod 404, the clamp 405 can accurately position and clamp the workpiece, thereby ensuring the stability and repeatability of the entire clamping process.
[0029] When in use, first move the clamping assembly 401 to a position close to the door panel 102 through the fixing assembly 402 to facilitate the installation of the optical lens, place the lens between the two clamps 405, and adjust the distance between the two clamps 405 through the telescopic rod 404 to ensure that the lens is firmly clamped; after clamping the lens, adjust the relative position of the lifting sleeve 403 on the telescopic rod 404 through the locking screw 413 to move the lens to a suitable height, thereby ensuring the accuracy of subsequent operations; next, the motor 408 in the device drives the screw 409 to rotate so that the slider 411 moves on the seventh guide rail 410, thereby driving the lens to move between the first detection device 501 and the second detection device 502. The two detection devices simultaneously perform surface shape detection on the top and bottom surfaces of the lens to obtain detailed surface shape data of the top and bottom surfaces of the lens, which will then be transmitted to the control system. After calculation and analysis, the system will derive the best polishing route to ensure that the surface of the lens reaches the expected accuracy and smoothness; after obtaining the best polishing route, the slider 411 continues to move on the seventh guide rail 410, driving the lens to continue to move between the first polishing mechanism 2 and the second polishing mechanism 3; the vacuum box 1 begins to evacuate to ensure that the lens remains stable during the polishing process, and then the first polishing mechanism 2 and the second polishing mechanism 3 perform synchronous polishing processing on the top and bottom surfaces of the lens, and drive the ion source to move through the three-axis drive device to obtain precise control; after the polishing process is completed, the vacuum box 1 will complete the inflation operation to restore it to a normal pressure state; the motor 408 is started again to drive the slider 411 to move, so that the optical lens moves along the seventh guide rail 410 to a position close to the door panel 102 for easy disassembly, and the telescopic rod 404 retracts outward to contact and release the clamping of the lens, completing the entire disassembly process.

Based on these data, the two ion sources can flexibly set different ion source parameters according to the different surface shapes of the upper and lower surfaces of the lens, and the two ion sources can plan their respective polishing paths respectively, and calculate the optimal residence time according to the specific conditions of the lens surface, thereby generating two independent processing codes. Through this improvement, the polishing device can not only improve the processing accuracy of the optical lens, but also significantly improve the production efficiency, and ultimately provide users with higher quality optical products.

The slider 411 is provided with a first threaded hole, and the screw 409 is threadedly connected to the first threaded hole, so that the slider 411 can rotate along the screw 409 and achieve precise positioning. The output shaft of the motor 408 is fixedly connected to the screw 409. Driven by the motor 408, the slider 411 can reciprocate along the seventh guide rail 410. The reciprocating motion of the slider 411 makes the movement of the device in the front and rear directions more flexible and efficient.
[0038] The displacement of the lens position has an adverse effect on the processing effect. Therefore, in one embodiment, a second threaded hole is provided on the side wall of the lifting sleeve 403, and a locking screw 413 is provided on the second threaded hole, and one end of the locking screw 413 passes through the second threaded hole and abuts against the support rod 412. The second threaded hole is installed in conjunction with the locking screw 413, and one end of the locking screw 413 passes through the second threaded hole and is in close contact with the support rod 412. Such a design enables the lifting sleeve 403 to be positioned more stably during the up and down movement, thereby improving the reliability of the overall equipment and the accuracy of operation. In this way, the lifting sleeve 403 can effectively prevent displacement caused by vibration or external force when performing its function, ensuring the stable operation of the equipment in various working environments.
