Problems solved by technology

Due to the small space in the vacuum layer of vacuum glass and the transparency of the glass, the protection and activation of the getter needs to be considered, so it is very difficult to place the getter in the vacuum layer
The traditional method of placing the getter in the vacuum glass is to first package the getter under vacuum, and then place it in the groove pre-opened on the glass. After sealing the edge of the vacuum glass, vacuuming, and sealing the suction port , and then use laser or infrared rays to open the package of the getter to activate the getter. The disadvantage of this method is that the encapsulation and placement process of the getter is complicated, the amount of the getter is small, and the appearance and mechanical properties of the glass are affected.

Abstract

The invention relates to a double-vacuum-layer glass getter sealed placement structure. The structure has the following characteristics: one round hole is drilled on each of the upper glass and the intermediate glass of vacuum glass, such that air-exhaust ports are prepared; one round pipe is prepared and is inserted in each of the air-exhaust ports; the lower parts of the round pipes are welded with glass, and the upper parts of the round pipes form sealing grooves with the air-exhaust ports; sealing caps are provided on the upper parts of the sealing grooves; the edges of the sealing caps are inserted into the sealing grooves; when the glass is edge-sealed; a getter is placed into the air-exhaust ports, and the ports are covered by using the sealing caps; a metal solder is placed in the sealing grooves or on the sealing caps; the air-exhaust ports are vacuumed and heated, such that the getter is automatically activated under high temperature and high vacuum, and also the metal solder is molten into liquid under the high temperature; the liquid is retained in the sealing grooves, and the edges of the sealing caps are immersed in the liquid; the air-exhaust ports are automatically sealed with a liquid sealing principle, and the getter is sealed in the vacuum layers. The method provided by the invention is suitable for mass productions. With the method, vacuum glass production efficiency and qualification rate can be greatly improved, and production cost can be reduced.

Description

technical field [0001] The invention belongs to the field of vacuum glass, and in particular relates to a sealed placement structure of a double-vacuum layer 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...
