Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to an evaporation coating device for optical lenses. Background Art

[0002] Optical coating refers to the process of coating a layer (or multiple layers) of metal (or dielectric) film on the surface of optical parts. The purpose of coating on the surface of optical parts is to reduce or increase the reflection, beam splitting, color separation, light filtering, polarization and other requirements of light. The coating of optical lenses is achieved by evaporating the coating.

[0003] For example, the optical lens coating evaporation device with the authorization announcement number "CN210458347U" is provided with a film frame. The staff lifts the fixing rod and places the evaporation film on the top of the film frame so that the four sides of the evaporation film are all located below the fixing rod. Then the fixing rod is lowered and the four sides of the evaporation film are fixed on the top of the film frame by the pressure pad. Finally, the buckle piece is pushed upward so that the buckle piece buckles to the top of the fixing rod to fix the fixing rod. The operation is simple and convenient, which is convenient for the staff to place or replace the evaporation film. It is firmly fixed and will not cause the phenomenon that the rest of the film body falls after a part of the film body evaporates. However, the device requires the operator to manually push the buckle piece to fix the fixing rod, and then fix the film frame through the fixing rod. The working time is long, which increases the workload of the operator and reduces the working efficiency of the device. After the device completes the coating of the optical lens, the operator needs to open the film frame and then take out the optical lens after the coating is completed. The coated optical lens is easy to cause burns to the operator, which reduces the safety of the device. Utility Model Content
