Abstract

The invention relates to a sealing tightness testing device for a high-performance battery. The sealing tightness testing device comprises a supporting frame device, a supporting cabinet and a testing device, wherein the supporting cabinet and the testing device correspond with the supporting frame device. The testing device is arranged below the supporting cabinet. The supporting cabinet is provided with a checking device. The checking device is connected with the injection inlet of the battery through a testing tube. The end of the injection inlet and the testing tube is connected with a sealing ring. The supporting frame device comprises a placing board and supporting columns which are arranged at two sides of the placing board. The testing device comprises a testing trough, a lifting device, and a placing rack device which is fixedly connected with the lifting device and is used for placing the battery. Through arranging a movable pressing rod, the sealing tightness testing device can test batteries in different specifications, thereby realizing multiple functions. Furthermore through an air pressure instrument in the checking device, a user can clearly determine whether the sealing tightness of the battery is qualified. The sealing tightness testing device has advantages of simple structure, high automation degree, high operation stability, etc.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a leak detection device for high-performance storage batteries. Background technique [0002] As we all know, batteries have the advantages of low cost, large capacity range, easy maintenance, and long service life, so they are widely used in various fields. In the battery manufacturing process, detection is a very important link, and the detection of battery airtightness is the most important among many detection links, especially the airtightness detection of valve-regulated sealed batteries. If the battery is not well sealed, it will cause many problems such as liquid leakage, rapid drop in open circuit voltage, and decline in battery charging performance, and may even cause serious disasters such as fire. But the existing storage battery airtight detection device is expensive and complicated to operate. [0003] For above-mentioned technical problem, so need to im...
