Novel cylindrical battery formation and capacity grading jig

Abstract

The invention discloses a novel cylindrical battery formation and capacity grading jig. The jig comprises an upper jig part and a lower jig part, wherein the upper jig part comprises an upper probe combination, an upper circuit board and an upper shell. The upper circuit board is mounted at one side of the upper shell, and the upper probe combination is mounted at one side of the upper circuit board. The jig lower part comprises a cylindrical battery, a lower probe combination, a lower circuit board and a lower housing, wherein the lower circuit board is mounted at the inner side of the lowershell, and the lower probe combination is mounted on the lower circuit board. The jig improves the probe replacement and maintenance efficiency, improves the percent of pass of products, reduces the shutdown probability of equipment, and reduces the use and maintenance cost.

Description

technical field [0001] The invention relates to the technical field of formation and containment of cylindrical batteries, in particular to a novel cylindrical battery formation and containment jig. Background technique [0002] With the increasingly serious energy crisis and environmental problems, under the strong support of the state for the new energy industry, the key technologies of power batteries have gradually matured, and various power batteries have been widely used in electric cars, electric motorcycles, electric bicycles, solar energy, mobile communications Terminal products and energy storage products. [0003] Battery formation is an essential process in the battery manufacturing process. The quality of capacity and formation is directly related to the overall performance of the battery, the yield rate and the service life of the battery in the later period. The structural design of the jig is very important to the whole process, but the traditional equipment...

AI Technical Summary

Problems solved by technology

[0004] There are the following disadvantages in the existing technology: 1. The jig and the probe are separated, which requires higher alignment accuracy and installation requirements for the entire equipment, which increases the cost of the equipment, thereby increasing the cost of producing batteries

2. The fixture is separated from the probe, and the installation of the probe inside the equipment will cause problems such as maintenance diagnosis of the entire equipment and probe replacement
