A lithium battery module assembly production process

Abstract

This application relates to a lithium battery module assembly production process, and relates to the technical field of lithium battery module lines, which includes the following steps: S1. Loading materials at the loading station; S2. Detecting a single lithium battery at the single battery detection station. The internal resistance and voltage of the battery; S3, welding the lithium battery module at the welding station; S4, testing the welded lithium battery module at the lithium battery module testing station; S5, cutting the material at the cutting station. During testing and welding, the lithium battery modules are placed on the tray to reduce the positional deviation of the lithium battery module when it moves on the conveyor belt. When the tray is processed at the corresponding station, it is separated from the conveyor belt in the vertical direction to ensure The positioning accuracy of the module in the horizontal direction and the height direction, thereby enabling this process to reduce the displacement of the lithium battery module during the assembly and welding process, so as to reduce the occurrence of dimensional errors after welding and other adverse conditions.

Description

technical field [0001] The present application relates to the technical field of lithium battery module lines, in particular to a lithium battery module assembly production process. Background technique [0002] In the production of traditional lithium battery modules, it is often necessary to manually test the terminals on a single lithium battery, and then sort and weld the qualified lithium batteries according to the actual design voltage, so that all batteries in the same lithium battery module series or parallel. In order to facilitate the movement of lithium batteries during the test process, lithium batteries are often transported on a conveyor belt at the production site, thereby reducing manual labor. [0003] Regarding the above-mentioned related technologies, the inventor believes that there are the following defects: the lithium batteries directly placed on the conveyor belt usually need to be removed and placed on the workbench beside the conveyor belt for test...

AI Technical Summary

Problems solved by technology

[0003] For the related technologies mentioned above, the inventor believes that there are the following defects: the lithium battery directly placed on the conveyor belt usually needs to be removed and placed on the workbench beside the conveyor belt for testing or welding, and then put back on the conveyor belt

During the process of the lithium battery going back and forth to the conveyor belt, the position of the lithium battery in the same lithium battery module is prone to shift when welding is not completed, resulting in the occurrence of adverse conditions such as the size and specification of the lithium battery module, which affects the economy. benefit
