A glass coating production line

Abstract

The invention provides a glass film-plating production line. The glass film-plating production line comprises an inlet chamber, an inlet buffering chamber, an inlet transition chamber, a sputtering chamber, an outlet transition chamber, an outlet buffering chamber and an outlet chamber in sequence along the conveying direction of a glass material; a conveying roller, which is parallel to the glass material, is paved in each of the chambers, and an exhausting hole connected with a vacuum system is arranged in each of the chambers; the inlet transition chamber and the outlet transition chamber are provided with separation devices; the separation devices comprise an upper separation device and a lower separation device; the upper separation device is provided with an upper separation plate for extending to an upper side of a glass material conveying plane from top to bottom; the lower separation device is provided with a lower separation plate for extending to a lower side of the glass material conveying plane from bottom to top; a lower edge of the upper separation plate is higher than an upper surface of the conveying roller; an upper edge of the lower separation plate is lower than the upper surface of the conveying roller; a material channel for the glass material to pass through is formed between the upper separation plate and the lower separation plate; the upper separation plate and the lower separation plate are aligned with or are diagonally opposite to the glass material conveying direction.

Description

technical field [0001] The invention relates to the field of glass coating production equipment. Background technique [0002] Glass coating is to coat one or more layers of metal, alloy or metal compound films on the glass surface to change the optical properties of the glass to meet certain specific requirements. [0003] Glass coating is achieved by filling a small amount of working gas (such as Ar, O 2 , N 2 etc.), the plasma is formed in the sputtering chamber through the discharge between the electrodes, and the metal target is bombarded by ions, so that the metal particles in the metal target overflow and gradually deposit on the glass surface to form a metal film or a metal compound film. [0004] Since the glass coating process needs to be carried out in a high vacuum environment, and the influence of air impurities on the working gas needs to be eliminated to ensure the quality of the coating, a series of transition chambers are required before the glass material...

AI Technical Summary

Problems solved by technology

[0007] In the process of realizing the present invention, the inventor has found that there is the following problem in the prior art: because in the prior art, the pressure difference between the inlet chamber and the atmospheric environment is relatively large, the period of deflation-vacuumizing the inlet chamber is obviously longer than that of The degassing-vacuumizing cycle of other chambers, so the bottleneck that leads to improving the efficiency of the entire glass coating production line lies in the degassing-vacuumizing cycle of the inlet chamber. If this time period cannot be effectively shortened, the efficiency of the glass coating production line cannot be effectively improved, affecting Product production speed, and lead to waste of target material
