Placement structure of vacuum glass getter and method of making the same

Abstract

An accommodating structure of vacuum glass getter is characterized in that a hole is formed in the upper glass of vacuum glass so as to form an extraction opening; a sealed groove is formed in the upper surface of the upper glass and in a position at the periphery of the extraction opening; a sealing cover is arranged on the sealed groove; the edge part of the sealing cover is inserted into the sealed groove; after the edges of the upper glass and lower glass are sealed, the vacuum glass getter is put into the extraction opening; the sealing cover is closed; metal solder is put into the sealed groove or onto the sealing cover; vacuum pumping and heating are perform at the extraction opening; the vacuum glass getter is activated automatically under the conditions of high temperature and high vacuum while the metal solder is molten into liquid due to high temperature; the liquid is kept in the sealed groove; the edge part of the sealing cover is immersed in the liquid; the extraction opening is sealed automatically according to the liquid seal principle; the vacuum glass getter is sealed in a vacuum layer; after temperature reduction, the liquid freezes, so as to realize airtightness sealing. According to the manufacture method provided by the invention, mass production can be realized, the production efficiency and qualification rates of vacuum glass can be greatly improved, and the manufacturing cost of the vacuum glass is lowered.

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. Background technique [0002] 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. [0003] 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 vacuum. The m...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a new type of vacuum glass getter placement structure and its manufacturing method for the defects of the existing vacuum glass getter placement structure. The manufacturing method of the placement structure is simple, and the vacuum glass produced, including the tempered vacuum glass, can overcome the deficiency of the getter in the prior art, 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
