Description

Technical Field

[0001] This utility model relates to the field of battery cell production technology, and specifically to a battery cell performance testing device. Background Technology

[0002] During the battery cell production process, it is generally necessary to test the battery cells to confirm whether the quality of the battery cells meets the process standards; and the battery cell testing process is generally carried out by connecting the battery cell connector to an external testing system to realize the performance testing of the battery cells.

[0003] When the flexible circuit board (FPCB) is short, the large end faces of the battery cell and the connector are generally parallel to each other, meaning both the battery cell and the connector are in a horizontal position for convenient testing. However, when the FPCB is long, it often needs to be bent to reduce the overall usable space of the battery cell. Therefore, after bending the FPCB, the large end faces of the battery cell and the connector are often located in different planes. Furthermore, to ensure the aesthetics and consistency of the battery cell after production, the large end face of the connector is generally bent to be perpendicular to the large end face of the battery cell.

[0004] Existing battery cell performance testing equipment typically uses devices where the large end face of the battery cell and the large end face of the battery cell connector are parallel to each other. This only meets the performance testing needs of battery cell products with short flexible circuit boards. For battery cell products with longer flexible circuit boards and where the large end face of the battery cell and the large end face of the battery cell connector are located on different planes, testing can generally only be performed manually using auxiliary fixtures. This is not only inefficient, but also prone to damaging the flexible circuit board and battery cell connector if the manual operation is improper. Utility Model Content

This device combines a battery cell flipping mechanism, a battery cell loading mechanism, and a battery cell testing mechanism to automate the performance testing of battery cell products where the battery cell and its connector are located in different planes.
