Lithium battery module assembly production process

Abstract

The invention relates to a lithium battery module assembly production process, and relates to the technical field of lithium battery module lines. The lithium battery module assembly production process comprises the following steps: S1, feeding at a feeding station; S2, detecting the internal resistance and voltage of a single lithium battery at a single battery detection station; S3, welding a lithium battery module at the welding station; S4, detecting the welded lithium battery module at a lithium battery module detection station; and S5, discharging at a discharging station. According to the invention, during testing and welding, lithium battery modules are placed on trays so as to reduce the position deviation of the lithium battery modules when the lithium battery modules move on a conveying belt, and the trays are separated from the conveying belt in the vertical direction when the trays are machined at the corresponding stations so as to ensure the positioning accuracy of the lithium battery modules in the horizontal direction and the height direction, so that the displacement of the lithium battery module in the assembling and welding process can be reduced, and the bad conditions of size errors and the like after welding are reduced.

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
