Power battery cover plate helium leak detection system

Abstract

The invention discloses a power battery cover plate helium leak detection system comprising a feeding conveyor belt, a first discharging conveyor belt, and a second discharging conveyor belt. A first vacuum leak detection box is arranged on one side of a first dust collection box. A second vacuum leak detection box is arranged on one side of a second dust collection box. A linear module II, which is connected with a linear module III and a linear module IV, is arranged above the first vacuum leak detection box and the second vacuum leak detection box. A linear module I, the linear module III, the linear module II and the linear module IV are equipped with vacuum chucks at the bottom. A helium leak detector is arranged on one side of the first vacuum leak detection box. With the system adopted, online and full-automatic detection, simultaneous feeding of multiple cover plates, PLC programmed control, sequential and independent detection of cover plates, automatic discharging, sorting, and distinguishing between qualified and unqualified products can be realized. Full-automatic and intelligent power battery cover plate helium leak detection is realized. The mechanical structure is intelligent. The technological process is reasonable and perfect. The efficiency is improved. The accuracy is ensured.

Description

technical field [0001] The invention relates to a leak detection system for a power battery, in particular to a helium leak detection system for a power battery cover. Background technique [0002] The power battery is an important part of the new energy battery. The power battery hinders the development of new energy vehicles. Therefore, the safety and practical performance of the battery are particularly important performance parameters, and the sealing and connection effect of the power battery cover is one of them. The key point, good sealing and connection effects can increase the safety performance of the battery and the convenience and quickness of the battery assembly into a linear module, etc., especially to prevent helium leakage, which requires helium leak detection on the power battery cover to ensure Its tightness, but the traditional power battery helium leak detection system has certain shortcomings. The existing manual system, the lower cabins are connected t...

AI Technical Summary

Problems solved by technology

A few large leaks may occur, and helium gas is pumped into the leak detector, resulting in a high background level, making it difficult to continue leak detection

And the efficiency is low, the precision is not high
