Device and method for automatically removing oxygen and moisture from transition cabin of vacuum glove box

Abstract

The invention provides a device and a method for automatically removing oxygen and moisture from a transition cabin of a vacuum glove box. An oxygen sensor module, a moisture sensor module, an air pressure sensor module, a transition cabin vacuum control module, a transition cabin inert gas control module, a transition cabin bracket access control module and a processor are arranged; the oxygen sensor module, the moisture sensor module, the air pressure sensor module, the transition cabin inert gas control module, the transition cabin vacuum control module and the transition cabin bracket access control module are electrically connected with the processor; the oxygen sensor module, the moisture sensor module and the air pressure sensor module respectively collect data in the transition cabin and send the data to the processor; and the processor carries out processing according to the received data and sends corresponding instructions to control the working states of the transition cabin inert gas control module and the transition cabin vacuum control module, so that moisture and oxygen in the transition cabin are automatically removed, and automatic entering and exiting of a transition cabin tray are achieved.

Description

technical field [0001] The invention relates to the field of vacuum equipment, in particular to a device for automatically removing oxygen and moisture in a transition chamber of a vacuum glove box. Background technique [0002] The vacuum glove box is a laboratory equipment that fills the box with high-purity inert gas and circulates to filter out the active substances. The glove box is mainly composed of a box body, a transition chamber, gas purification, automatic control, etc., mainly for O 2 , H 2 Clearance of O et al. Widely used in moisture-free, oxygen-free and dust-free environments, such as in the research and development and production of lithium-ion batteries and materials, semiconductors, supercapacitors, etc. [0003] The transition chamber is used as a transition space between the main box and the outside of the box. When in use, in order to avoid introducing moisture and oxygen into the main box, tools and materials need to be put into the transition room ...

AI Technical Summary

Problems solved by technology

But sometimes, because the user is not familiar with the operation process or has not completed the operation according to the prescribed process, he hurriedly transfers the tools or materials into the main box. Because the moisture and oxygen are not completely removed, the oxygen and moisture in the main box The increase of the content will not only easily affect the effect of follow-up work, but also shorten the use time of the main box, and the main box must be frequently regenerated and restored after not being used for a long time
