[0026] The device is used in the coating process of optical lenses. First, the optical lenses to be coated are placed in the lens modules 24 after being washed. In this process, the spring assembly 241 in the lens module 24 is compressed, and the wedge-shaped block 242 is pressed and fixed on the optical lenses under the pressure of the spring assembly 241. After the optical lenses are completely placed in the lens module 24, the mounting plate 23 is placed on the multi-sided shaft 22 by the handle, and then installed on the output shaft of the first motor 21. Then, the electric push rod 17 is started by the controller 15, the output shaft of the electric push rod 17 drives the gear ring 18 to descend, and the gear ring 18 is pressed tightly on the output shaft of the first motor 21 in the descending process.
