[0002] With the development of technology, optical lenses have been widely used in digital cameras, mobile phones, projectors, camcorders and other technical fields. During the production process, optical lenses need to ensure high purity, transparency and uniformity. The coating process is one of the important steps in the subsequent processing. Using a coating machine, a single or multiple thin film is deposited on the surface of the optical lens through physical or chemical methods. The interference effect generated by the incident, reflected and transmitted light at the thin film interface is used to achieve focusing, collimation, filtering, reflection and refraction. In the coating process, a coating plate is generally used to fix the optical lens, thereby facilitating the coating work. However, in the existing coating technology, the optical lens is simply placed in a reserved placement slot. During the coating process, it is easily affected by external factors, which can cause it to shift and affect the coating effect. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content

[0024] In this technical solution, a coating plate 4 is fixed to the top of the coating base 1. Twenty lens placement slots 2 are evenly and equidistantly arranged on the top of the coating plate 4 for placing the lens coating.

The lens can be placed on the lens carrier plate 15 and the lens pressing ring 11 is set on the lens carrier plate 15, thereby limiting the lens inside the lens pressing ring 11. One end of the pressing plate 9 rotates in the rotating seat 7 through the rotating shaft 8, and the other end is connected to the lens pressing ring 11 through the connecting rod 10, thereby driving the movement of the lens pressing ring 11 on the lens carrier plate 15. The pressing plate 9 is made of elastic material. When the lens pressing ring 11 is placed on the lens carrier plate 15, the positioning mechanism 12 is inserted into the positioning slot 13 to fix the lens pressing ring 11.
