Hemispherical glass outer surface film coating device and method

Abstract

The invention relates to a hemispherical glass outer surface film coating device and method. The hemispherical glass outer surface film coating device comprises a film coating cavity, a film coating mechanism, an adjustable fixing mechanism and a rotating mechanism. The film coating mechanism is arranged in the film coating cavity and used for conducting the film coating technology on multiple circular ring surfaces in sequence. The adjustable fixing mechanism is arranged on the film coating cavity, and the position of the adjustable fixing mechanism can be adjusted according to the film coating position of a piece of hemispherical glass. The rotating mechanism is connected with the adjustable fixing mechanism in a pivot joint mode and can be driven by the adjustable fixing mechanism to adjust the position of the rotating mechanism. The rotating mechanism is used for achieving the process that when the film coating technology is conducted, the rotating mechanism is connected with the hemispherical glass, drives the hemispherical glass to rotate, controls the multiple circular ring surfaces to face the film coating mechanism in sequence by rotating around the pivot joint end of therotating mechanism, and conducts the film coating technology on the multiple circular ring surfaces in sequence. According to the hemispherical glass outer surface film coating device and method, thehemispherical glass is divided into the multiple circular ring surfaces, the multiple circular ring surfaces are subjected to the film coating technology in sequence, and therefore the whole film coating process can be accomplished only through one cathode.

Description

technical field [0001] The invention relates to a film coating device and a film coating method, in particular to a film coating device and a film coating method for the outer surface of hemispherical glass. Background technique [0002] With the growth of the national economy, the market demand for the glass industry is increasing, and there are more and more glass forms required, including the special demand for hemispherical glass. [0003] At the same time, in order to improve the performance of the glass, in the prior art, the magnetron sputtering process is usually used to coat the surface of the glass, so that the glass has the characteristics of high gloss, oxidation resistance, acid and alkali resistance, and ultraviolet resistance. Played a very good protective effect on the glass. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Due to the particularity of the...

Problems solved by technology

[0005] Due to the particularity of the hemispherical glass, the entire outer surface of the glass is a spherical surface. During the magnetron sputtering coating, the cathode tooling in the existing magnetron sputtering device cannot meet the coating requirements, and a special cathode tooling is required, resulting in increased manufacturing. cost, and the thickness of the film layer during coating cannot be guaranteed to be uniform and stable
