Optical lens vacuum coating jig

Abstract

The invention relates to the technical field of film coating, in particular to an optical lens vacuum film coating jig which comprises a shell, an interlayer is arranged on the side wall of the shell, a spiral heat conduction pipe is arranged in the interlayer, a vacuum film coating cavity is formed in the shell, a rodless air cylinder is fixedly connected to the right side in the vacuum film coating cavity, and a film coating emission source is arranged on the left side of the rodless air cylinder. The outer surface of the bottom end of the shell is fixedly connected with a motor, a rotating shaft of the motor is fixedly connected with a disc set, the upper surface of the disc set is fixedly connected with a fastening mechanism, the fastening mechanism comprises a plurality of spring sets, and the outer surface of each spring set is provided with a rubber coating. The rotating shaft of the motor rotates to drive the disc to rotate, so that the optical lens is uniformly coated with a film, the spring sets form the lens placement frames suitable for different specifications by utilizing the elasticity of the springs, the lens placement frames are suitable for fastening the lenses of different specifications, and the actual use performance of the vacuum coating machine for the optical lens is improved.

Description

technical field [0001] The invention relates to the technical field of coating, in particular to a vacuum coating tool for optical lenses. Background technique [0002] Vacuum coating machine mainly refers to a type of coating that needs to be carried out under a high degree of vacuum, including many types, including vacuum resistance heating evaporation, magnetron sputtering, etc. The main idea is to divide it into two types: evaporation and sputtering, which require coating The substrate is called the substrate, and the material to be plated is called the target. The substrate and the target are in the same vacuum chamber. Evaporation coating generally heats the target so that the surface components are evaporated in the form of atomic groups or ions, and settle on the substrate. The surface is formed into a thin film through a film formation process. [0003] Vacuum coating the optical lens can reduce the reflected light on the surface of the lens, make the vision clear,...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the coating operation of optical lenses is to place the lens in a coating machine, and under vacuum conditions, vapor-deposit a layer or multi-layer films on the lens substrate upwards from the evaporation source, During this period, the optical lenses need to be placed on the rack. It is difficult to adjust the traditional racks to adapt to lenses of different shapes and thicknesses. A rack can often only place optical lenses of one specification, which has great limitations.
