Description

Getter vacuum cavity feeding device

Technical Field

The utility model relates to vacuum glass, in particular to a production tool of the vacuum glass.

Background

The vacuum glass is a novel glass deep processing product and is developed based on the principle of a vacuum flask. The structure of the vacuum glass is similar to that of hollow glass, but the difference is that the gas in the cavity of the vacuum glass is very thin and almost close to vacuum.

The vacuum glass is formed by sealing the peripheries of two pieces of flat glass, vacuumizing the gap between the two pieces of flat glass and sealing an exhaust hole, wherein the gap between the two pieces of flat glass is 0.3mm, at least one of the two pieces of vacuum glass is generally low-radiation glass, so that the heat dissipated by conduction, convection and radiation of the vacuum glass is reduced to the minimum, and the working principle of the vacuum glass is the same as that of a glass vacuum flask. The vacuum glass is a great achievement of cooperative cooperation of glass technology, material science, vacuum technology, physical measurement technology, industrial automation, building science and the like, and multiple subjects, multiple technologies and multiple processes.

In order to ensure the vacuum degree between the vacuum glasses, a getter is required to be put between the vacuum glasses, so that even a small amount of gas enters the vacuum cavity of the vacuum glass, the gas can be adsorbed by the getter, and the vacuum degree is ensured. Therefore, the getter is required to be put in the vacuum glass production, the getter is required to be supplemented in the vacuum glass production, the vacuum chamber is required to be opened under normal conditions, the getter is required to be put in a feeding mechanism of the vacuum chamber, the vacuum of the vacuum chamber is damaged, the vacuum chamber is required to be vacuumized again in the subsequent production, time is wasted, and production consistency is damaged.
