[0002] Currently, 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 industry employs various methods to manufacture optical lenses to meet market demands for different specifications. Simultaneously, to reduce costs and improve efficiency, mass production is implemented to meet the demand for optical lenses. Generally, coating is one of the important steps in subsequent processing. Coating refers to depositing single or multiple thin films on the surface of optical elements using physical or chemical methods. The interference effect generated at the thin film interface by incident, reflected, and transmitted light achieves effects such as focusing, collimation, filtering, reflection, and refraction.

[0003] 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 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
