Abstract

The invention discloses equipment for detecting negative pressure leakage detection. The equipment comprises a detection box, a negative pressure butt joint assembly and a negative pressure detection part, the detection box comprises an outer box body and an inner support, and a detection cavity is formed in the outer box body; the inner support is arranged in the detection cavity of the outer frame body; the negative pressure butt joint assembly comprises a plurality of negative pressure detection columns which are parallel to one another, the negative pressure detection columns are arranged on the top of the outer box body side by side in pairs, and every two negative pressure detection columns in pairs are connected with each other through a connecting rod; the negative pressure detection component is arranged in the detection cavity of the outer box body and comprises a digital display meter and a digital display meter mounting piece, the digital display meter is arranged in the detection cavity of the outer box body through the digital display meter mounting piece, and an external connector of the digital display meter is communicated with the negative pressure detection column pipeline. The gas leakage detection device has the beneficial effects that whether gas in the negative pressure pipeline of the formation equipment leaks or not can be rapidly detected, the production process of gas pressure leakage detection can be controlled, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of leak detection tooling, in particular to a device for detecting negative pressure leak detection. Background technique [0002] The formation process is an important step in the production process of prismatic lithium batteries, and the purpose is to activate the battery. During the chemical formation process of the battery, gas will be generated inside, and negative pressure is generally used to extract the gas in the industry. As the gas is discharged, part of the electrolyte in the battery also enters the negative pressure pipeline, and over time, crystals are formed in the pipeline, which blocks the pipeline and affects the quality of the battery. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention proposes a device for detecting negative pressure leaks. [0004] The present invention is achieved through the following technical solutions: [0005] A device for dete...
