Description

Technical Field

[0001] The present application relates to the technical field of soft-pack battery preparation, and in particular to a soft-pack battery tab shaping device. Background Art

[0002] At present, on the automated soft-pack lithium battery production line, the batteries that have been automatically packaged will be placed sideways in a dedicated material frame. Multiple batteries can be placed in each material frame and transferred to the next process through an automatic logistics line. During the automatic packaging process, the battery tabs will be partially bent due to force. In the process of loading the battery into the material frame, the interaction between the top seal air bag and the material frame will also cause the battery tabs to bend. The thicker the battery, the more serious the bending of the tabs. Currently, after high-temperature aging, the material frame containing the battery will automatically flow into the capacity separation test process for testing. If the battery tabs are bent too much and exceed the guide spacing of the capacity separation test clips, the tabs will fold, resulting in poor contact of the battery tabs during the capacity separation test, affecting the test results and causing poor product appearance.
