Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, and in particular to a lens coating device for optical lens processing. Background Technology

[0002] In the production process of optical lenses, in order to reduce or increase light reflection, beam splitting, color separation, filtering, polarization, etc., it is usually necessary to coat the surface of the optical lens with one (or multiple) metal (or dielectric) thin film. In order to improve the imaging quality of the optical lens, optical coatings need to be applied to both sides of the optical lens. Specific types include vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy and PLD laser sputtering, etc., mainly divided into evaporation and sputtering.

[0003] Existing coating devices coat one side of the optical lens element. After coating one side, the optical lens element needs to be flipped over to continue coating. This is inefficient and the direct contact between the operator and the optical lens element during flipping inevitably contaminates the optical element.

[0004] Therefore, we propose a lens coating apparatus for optical lens processing. Utility Model Content

[0029] Example 1: A lens coating apparatus for optical lens processing, such as... Figures 1-2 As shown, the coating machine 10 is a mature existing technology and will not be described in detail here. The front end of the inner wall of the coating machine 10 is movably mounted with a door 11 via a hinge. The top of the coating machine 10 is provided with a multi-angle rotating device 12. The multi-angle rotating device 12 includes a mounting cover 13, and the lower end of the inner wall of the mounting cover 13 is threadedly connected to the upper end of the outer wall of the coating machine 10. The top of the mounting cover 13 is fixedly mounted with a mounting shield 14, and the top of the mounting shield 14 is provided with a multi-angle rotating mechanism 15. By setting the multi-angle rotating mechanism 15, the optical lens can be rotated at multiple angles and uniformly coated during the coating process, thereby ensuring that both sides of the lens can be uniformly coated, improving coating efficiency and coating quality, and avoiding the contamination problem caused by direct contact between the optical lens and the operator.

[0030] Example 2: Based on Example 1, as follows Figure 3As shown, the multi-angle rotation mechanism 15 includes a servo motor 16, with the bottom of the servo motor 16 fixedly connected to the top of the mounting cover 14. A sun gear 17 is fixedly mounted on the output end of the servo motor 16. A retainer 18 is movably mounted on the upper end of the sun gear 17 at the output end of the servo motor 16. A first rotating frame assembly 19 is movably mounted on the left side of the inner wall of the retainer 18 via a rotating shaft. A second rotating frame assembly 20 is movably mounted on the right side of the inner wall of the retainer 18 via a rotating shaft, and the structure of the second rotating frame assembly 20 is the same as that of the first rotating frame assembly 19. A third rotating frame assembly 21 is movably mounted on the front end of the inner wall of the retainer 18 via a rotating shaft, and the structure of the third rotating frame assembly 21 is the same as that of the first rotating frame assembly 19. A fourth rotating frame assembly is movably mounted on the rear end of the inner wall of the retainer 18 via a rotating shaft. The rotating frame assembly 22, and the structure of the fourth rotating frame assembly 22 are the same as those of the first rotating frame assembly 19. The upper end of the outer wall of the first rotating frame assembly 19 is movably engaged with an internal gear ring 23, and the inner wall of the internal gear ring 23 is movably engaged with the upper end of the outer walls of the second rotating frame assembly 20, the third rotating frame assembly 21 and the fourth rotating frame assembly 22 respectively. The top of the internal gear ring 23 is fixedly connected to the top of the inner wall of the mounting cover 13. By setting a retainer 18, the first rotating frame assembly 19, the second rotating frame assembly 20, the third rotating frame assembly 21 and the fourth rotating frame assembly 22 are movably mounted in the retainer 18 through a rotating shaft. The structures of these rotating frame assemblies are the same, so they can perform planetary motion synchronously, which not only improves the stability and reliability of the coating device, but also makes the coating process more efficient and uniform.

[0031] Example 3: Based on Examples 1 and 2, as follows... Figure 4 As shown, the first rotating frame assembly 19 includes a planetary gear 24, and the top of the planetary gear 24 is movably connected to the inner wall of the cage 18 via a rotating shaft. One side of the outer wall of the planetary gear 24 is movably meshed with the outer wall of the sun gear 17, and the other side of the outer wall of the planetary gear 24 is movably meshed with the inner wall of the internal gear ring 23. A rotating column 25 is fixedly installed at the bottom of the planetary gear 24. Double-sided clamps 26 are evenly arranged on the outer wall of the rotating column 25. The double-sided clamps 26 are existing mature technology and will not be described in detail here.

[0032] The working principle of this utility model:

[0033] When the servo motor 16 starts, its output drives the sun gear 17 to rotate. The rotation of the sun gear 17 then drives the planetary gear 24, which meshes with it, to perform planetary motion within the cage 18. That is, the planetary gear 24 rotates around the center of the sun gear 17 and simultaneously rotates on its own axis. Since the other side of the outer wall of the planetary gear 24 is in movable engagement with the inner wall of the internal gear ring 23, the fixed state of the internal gear ring 23 restricts some degrees of freedom of the planetary gear 24, allowing the planetary gear 24 to move stably on a predetermined trajectory. As the planetary gear 24 rotates, the rotating column 25, which is fixedly mounted at the bottom of the planetary gear 24, also rotates. The double-sided clamps 26, which are evenly arranged on the outer wall of the rotating column 25, are used to clamp the optical lens to be coated. Since the double-sided clamps 26 rotate with the rotating column 25, multi-angle rotation of the optical lens can be achieved during the coating process, thereby ensuring that both sides of the lens can be uniformly coated. Furthermore, since the first rotating frame assembly 19, the second rotating frame assembly 20, the third rotating frame assembly 21, and the fourth rotating frame assembly 22 are movably mounted within the retainer 18 via rotating shafts, and these rotating frame assemblies have identical structures, they can perform planetary motion synchronously. This design not only improves the stability and reliability of the coating apparatus but also makes the coating process more efficient and uniform. In summary, this invention, by employing a multi-angle rotating device and a multi-rotating frame assembly design, achieves multi-angle rotation and uniform coating of optical lenses during the coating process, improving coating efficiency and coating quality, while avoiding contamination problems caused by direct human contact with optical lenses.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
