Film coating correction plate and assembly method thereof

Abstract

The invention provides a film coating correction plate which comprises a substrate, at least one wing panel with different lengths, and one aluminium foil paper, wherein the at least one wing panel can detachably and rotatably assembled on the substrate, the aluminium foil paper wraps the substrate and the at least one wing panel along an outer contour of the substrate and the at least one wing panel, thereby being capable of preventing influences of artificial tailoring on shapes of the film coating correction plate, improving quality and efficiency of the film coating, and being capable of changing shapes of the film coating correction plate to meet different demands. The invention further provides an assembly method of the film coating correction plate.

Description

technical field [0001] The invention relates to coating technology, in particular to a coating correction plate and an assembly method thereof. Background technique [0002] The coating machine includes a crucible and an umbrella frame set relative to the crucible. The umbrella frame is formed with multiple rings of receiving holes from the center to the edge, and each receiving hole accommodates one or more workpieces to be coated. During coating, the material in the crucible is bombarded by the electron beam after evaporation and reacts with the reaction gas, and then attaches to the workpiece to be coated to form a film layer, and the umbrella stand rotates so that the film gas obtained by the workpiece to be coated in the same circle of holding holes is basically the same , so that the film thicknesses of the workpieces to be coated in the same ring of receiving holes are basically the same. However, in general, the film gas concentration in several circles of holding ...

AI Technical Summary

Problems solved by technology

At present, the shape of the coating correction plate can depend on the shape of the substrate or the aluminum foil paper. The former foil wraps the substrate along the outline of the substrate. In this way, the shape of the coating correction plate is determined. When other shapes of the coating correction plate are required, it needs to be remade. , poor versatility

The latter’s aluminum foil is larger than the substrate and spread out and pasted on the substrate. However, at present, the aluminum foil is mainly obtained by manual cutting, which is difficult to follow a unified standard. It is often necessary to cut and test the coating to confirm the effect of the coating correction plate. Not only the quality of the coating is difficult Guaranteed and inefficient
