Vacuum glass getter placement structure and manufacturing method thereof

Abstract

The invention provides a vacuum glass getter placement structure which is characterized in that punching is performed on an upper piece of glass of vacuum glass to form an extraction opening, a sealing ring is prepared at the periphery of the extraction opening and the lower surface of the upper piece of glass, an annular sealing box is placed on a lower piece of glass, and a sealing cover is further arranged on the annular sealing box; after edges of the upper piece of glass and the lower piece of glass are sealed, the getter is placed into the extraction opening, the extraction opening is covered with the sealing cover, then metal solder is placed into the annular sealing box or on the sealing cover, the extraction opening is vacuumized and heated, the getter is automatically activated at high temperature and under high vacuum, meanwhile metal solder is melted into liquid at high temperature, the liquid is retained in the annular sealing box, edge parts of the sealing ring and the sealing cover are submerged into the liquid, the extraction opening is in self sealing by utilizing the liquid sealing principle and the getter is further sealed in the vacuum layer, and after cooling, the liquid is solidified, and air tightness seal is realized. According to the method provided by the invention, mass production can be realized, production efficiency and qualified rate of the vacuum glass are greatly improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to the field of vacuum glass, and in particular relates to a placement structure of a vacuum glass getter and a manufacturing method thereof. [0002] Background technique [0003] The existing vacuum glass is generally composed of two or three pieces of flat glass. The glass is sealed with low-temperature glass solder around the edges, and there is a tiny support in the middle. A thin layer of 0.1-0.2mm thickness is formed between the two pieces of glass by pumping air. Vacuum layer. Since there is no heat and sound transmission of gas, and the inner surface of the glass can have a transparent low-heat radiation film, the vacuum glass has good heat insulation and sound insulation effects, and is one of the best performance energy-saving glasses. [0004] The key technologies of the existing vacuum glass include: one is edge sealing, the other is the placement of supports, and the third is the acquisition and maintenance of vacu...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a novel vacuum glass getter placement structure and its manufacturing method in view of the defects in the placement structure of the existing vacuum glass getter. The manufacturing method of the placed structure is simple in process, and the manufactured vacuum glass, including tempered vacuum glass, can overcome the deficiencies in the prior art for placing getters, can effectively ensure the high vacuum degree of the vacuum layer of the vacuum glass, prolong the service life of the vacuum glass, and It can improve the production efficiency of vacuum glass containing getter and reduce the production cost
