Technical Field
[0001] The utility model relates to the technical field of lens processing, and specifically relates to a coating device for lens processing. Background Technique
[0002] The coating device for lens processing is usually called a coating machine. Such a device can coat various types of coating materials on the surface of the lens to change its optical properties or increase its wear resistance. These devices usually include components such as coating nozzles, motors, and fixing mechanisms to achieve an automated coating process;
[0003] Traditional coating devices for lens processing usually use clamping fixtures or clamping devices to fix the lens at a specific position or angle. These devices fix the lens by mechanical manual or hydraulic means for processing or other treatments;
[0004] Traditional coating devices for lens processing have the following problems: Since only a few or even a single lens can be fixed for coating at a time, multiple lenses cannot be clamped simultaneously, resulting in low production efficiency and inability to achieve batch processing, leading to an extended production cycle and increased costs. Moreover, manual adjustment of the clamping device is required to adapt to lenses of different sizes, increasing the manual operation and time costs during the production process. For this reason, we propose a coating device for lens processing. Content of the Utility Model

[0014] Furthermore, the adaptive clamping mechanism includes a sliding hole, a sliding column, a spring and a clamping plate. The sliding holes are respectively opened at one end of the first rack plate near the center of the workbench. The inner walls of the sliding holes are both slidably connected with the sliding columns. One end of each sliding column near the center of the workbench is fixedly connected with a clamping plate. A spring is fixedly connected between the outer side surface of the clamping plate and one end of the adjacent first rack plate near the center of the workbench. The springs are all sleeved on the outer surfaces of the sliding columns, and can automatically adjust the clamping force according to the different sizes of the lenses.
[0015] Furthermore, the fixing mechanism also includes a second gear and a rotating shaft. The rotating shafts are respectively rotatably connected between two vertically adjacent limiting plates. The upper and lower ends of each rotating shaft are fixedly sleeved with a second gear. The second gears are all meshed with the first rack plate adjacent to the left side, realizing the ability to clamp multiple lenses at the same time.
[0016] Furthermore, the fixing mechanism also includes a first gear, a second rack plate and a guiding sliding groove.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows: The coating equipment for lens processing of the present utility model has the following advantages:
[0020] 1. Place the lens between two longitudinally adjacent clamping plates, and then regulate the operation of the motor through the single-chip microcomputer. The rotation of the output shaft of the motor drives the rotation of the front lead screw. The front lead screw makes the second rack plate move to the right along the guiding chute through threaded connection and meshes with the uniformly distributed first gears to rotate, thereby driving the rotation of the upper and lower second gears fixed on the rotating shaft. The second gears then drive the rotation by meshing with the adjacent first rack plates, so that the first rack plates slide along the left inner wall of the limiting plate, gradually making the front clamping plate approach the outer surface of the lens. While the front clamping plate approaches the lens, the rotation of the front lead screw drives the rotation of the front third gear, which meshes with the rear third gear to rotate and drives the rotation of the rear lead screw. The rear lead screw makes the rear second rack plate move to the right along the guiding chute through threaded connection and meshes with the uniformly distributed first gears to rotate, thereby driving the rotation of the upper and lower second gears fixed on the rotating shaft. The second gears then drive the rotation by meshing with the rear adjacent first rack plates, so that the rear first rack plate slides along the left inner wall of the limiting plate, gradually making the rear clamping plate approach the outer surface of the lens until every two longitudinally adjacent clamping plates are in complete contact with the outer surface of the lens, ensuring the firmness and stability of clamping during coating, so that multiple lenses can be clamped simultaneously, more lenses can be processed at the same time, and the coating production cycle is shortened.
[0021] 2. When the clamping plate contacts lenses of different sizes, according to the size change of the lens, the clamping plate will feel different extrusion forces. For larger lenses, the extrusion force will make the clamping plate drive the sliding column to move along the inner wall of the sliding hole and compress the spring, while for smaller lenses, the spring will undergo elastic recovery, enabling the clamping plate to adaptively adjust its position, so that the clamping force can be automatically adjusted according to the different sizes of the lenses, ensuring a more stable clamping effect during the coating process and realizing a more flexible lens coating operation.

The fixing mechanism 7 further includes a first rack plate 702, a limiting plate 704 and an adaptive clamping mechanism 705.

The inside of the first rack plate 702 near one end of the center of the workbench 10 is provided with an adaptive clamping mechanism 705. The adaptive clamping mechanism 705 includes a sliding hole 7051, a sliding column 7052, a spring 7053 and a clamping plate 7054. The sliding holes 7051 are respectively opened at one end of the first rack plate 702 near the center of the workbench 10. The inner walls of the sliding holes 7051 are both slidably connected with the sliding columns 7052. The ends of the sliding columns 7052 near the center of the workbench 10 are both fixedly connected with the clamping plates 7054.

The fixing mechanism 7 further includes a first gear 701, a second rack plate 706 and a guiding chute 707. The guiding chutes 707 are respectively opened at the front and rear ends between the upper and lower inner walls of the installation groove 11.

The two lead screws 708 are respectively rotatably connected between the left and right inner walls at the front and rear ends of the installation groove 11. The middle parts of the lead screws 708 are both threadedly connected with the inside of the adjacent second rack plate 706.

The two third gears 709 are meshed and connected. The fixing mechanism 7 further includes a motor 711. The motor 711 is arranged on the inner wall of the right installation shell 9. The left end of the output shaft of the motor 711 is fixedly connected with the right end of the front lead screw 708. The input end of the motor 711 is electrically connected to the output end of the single-chip microcomputer 6. Before coating, the lens needs to be fixed on the fixing mechanism 7. First, open the sealing door 4, then place the lens between two longitudinally adjacent clamping plates 7054, and then control the motor 711 to operate through the single-chip microcomputer 6. The rotation of the output shaft of the motor 711 drives the front lead screw 708 to rotate. The front lead screw 708 makes the second rack plate 706 move to the right along the guiding chute 707 through threaded connection and meshes with the evenly distributed first gears 701 to rotate.Thus, the two gears 703 fixed at the upper and lower ends on the rotating shaft 710 are driven to rotate. The second gear 703 then rotates by meshing with the adjacent first rack plate 702, causing the first rack plate 702 to slide along the left inner wall of the limiting plate 704, gradually bringing the front clamping plate 7054 closer to the outer surface of the lens. While the front clamping plate 7054 approaches the lens, the front lead screw 708 rotates to drive the front gear 709 to rotate, which meshes and rotates with the rear gear 709, and drives the rear lead screw 708 to rotate. The rear lead screw 708 is threadedly connected to cause the rear rack plate 706 to move rightward along the guiding chute 707 and mesh and rotate with the uniformly distributed first gears 701, thus driving the two gears 703 fixed at the upper and lower ends on the rotating shaft 710 to rotate. The second gear 703 then rotates by meshing with the adjacent first rack plate 702 at the rear, causing the rear first rack plate 702 to slide along the left inner wall of the limiting plate 704, gradually bringing the rear clamping plate 7054 closer to the outer surface of the lens until every two longitudinally adjacent clamping plates 7054 are in full contact with the outer surface of the lens, ensuring the firmness and stability of the clamping, so that multiple lenses can be clamped simultaneously, more lenses can be processed at the same time, and the production cycle is shortened. When the clamping plate 7054 contacts lenses of different sizes, according to the size change of the lens, the clamping plate 7054 will feel different extrusion forces. For larger lenses, the extrusion force will cause the clamping plate 7054 to drive the sliding column 7052 to move along the inner wall of the sliding hole 7051 and compress the spring 7053. For smaller lenses, the spring 7053 will undergo elastic recovery, enabling the clamping plate 7054 to adaptively adjust its position, so that the clamping force can be automatically adjusted according to the different sizes of the lenses to ensure a stable clamping effect;
[0034] Wherein: it further includes a single-chip microcomputer 6, which is arranged at the front end of the right side of the coating housing 2, and the input end of the single-chip microcomputer 6 is electrically connected to the output end of the coating nozzle 12.
[0035] The working principle of a coating device for lens processing provided by the utility model is as follows: Before coating, the lens needs to be fixed on the fixing mechanism 7. First, open the sealing door 4, then place the lens between two longitudinally adjacent clamping plates 7054, and then regulate the operation of the motor 711 through the single-chip microcomputer 6. The output shaft of the motor 711 rotates to drive the front screw rod 708 to rotate. The front screw rod 708 drives the rack plate two 706 to move rightward along the guiding chute 707 through threaded connection and meshes with the uniformly distributed gear one 701 to rotate, thereby driving the gear two 703 at the upper and lower ends fixed on the rotating shaft 710 to rotate. The gear two 703 then drives the adjacent rack plate one 702 to rotate through meshing, causing the rack plate one 702 to slide along the left inner wall of the limiting plate 704, gradually bringing the front clamping plate 7054 closer to the outer surface of the lens. While the front clamping plate 7054 approaches the lens, the front screw rod 708 rotates to drive the front gear three 709 to rotate, meshes with the rear gear three 709 to rotate, and drives the rear screw rod 708 to rotate. The rear screw rod 708 drives the rear rack plate two 706 to move rightward along the guiding chute 707 through threaded connection and meshes with the uniformly distributed gear one 701 to rotate, thereby driving the gear two 703 at the upper and lower ends fixed on the rotating shaft 710 to rotate. The gear two 703 then drives the adjacent rack plate one 702 at the rear to rotate through meshing, causing the rear rack plate one 702 to slide along the left inner wall of the limiting plate 704, gradually bringing the rear clamping plate 7054 closer to the outer surface of the lens until every two longitudinally adjacent clamping plates 7054 are in full contact with the outer surface of the lens, ensuring the firmness and stability of clamping, so that multiple lenses can be clamped simultaneously, more lenses can be processed at the same time, shortening the production cycle. When the clamping plate 7054 contacts lenses of different sizes, according to the size change of the lens, the clamping plate 7054 will feel different extrusion forces. For larger lenses, the extrusion force will cause the clamping plate 7054 to drive the sliding column 7052 to move along the inner wall of the sliding hole 7051 and compress the spring 7053, while for smaller lenses, the spring 7053 will undergo elastic recovery, enabling the clamping plate 7054 to adaptively adjust its position, thereby being able to automatically adjust the clamping force according to the different sizes of the lenses to ensure a stable clamping effect. Then, regulate the operation of the coating nozzle 12 through the single-chip microcomputer 6 to coat the lenses uniformly distributed in the fixing mechanism 7. At the same time, regulate the operation of the motor 5. The output shaft of the motor 5 rotates to drive the rotating shaft 8 to rotate, and the rotating shaft 8 drives the lenses on the fixing mechanism 7 in the workbench 10 to rotate together, improving the uniformity of coating. However, during the coating process, the coating state can be observed through the transparent window 3.
[0036] It should be noted that the specific model of the single-chip microcomputer 6 disclosed in the above embodiments is S7-200. For the motor 5, it is recommended to select D180M-0160030B-E. The motor 711 can be selected as BMR-50. The coating nozzle 12 can be the coating nozzle on the HCMS-1212 magnetron sputtering coating equipment. The single-chip microcomputer 6 controls the operation of the motor 5, the motor 711 and the coating nozzle 12 by using the methods commonly used in the prior art.
[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
