[0002] With the wide application of lithium batteries, the requirements for various indicators of lithium batteries are getting higher and higher, especially the safety performance indicators. Therefore, after the winding of the batteries is completed, it is necessary to perform short-circuit detection on the batteries, because the short-circuited batteries are in the There is a safety hazard of explosion when in use
[0003] The existing short-circuit detection method is a single detection. The battery is on the conveyor belt, and the positive and negative tabs of the battery are passively in contact with the positive and negative electrodes of the short-circuit detector. The first-class problem may mistake the short-circuited cell as a qualified product

The invention discloses a lithium battery cell short-circuit detection device, comprising: a carrier plate, a lifting adjustment device, a cell clamping assembly and a short-circuit detector. The cell clamping assembly is fixedly connected with the carrying plate. For clamping the cell tabs, the short-circuit detector is connected to the cell clamping assembly for contacting the cell tabs to perform short-circuit detection, and the lift adjusting device is used to adjust the height of the carrier plate. During the detection process, the cells to be tested are clamped by the cell clamping components and are in a fixed state. Compared with the traditional detection method of passive contact between the cell tabs and the short-circuit detector, the accurate position of the cells can be ensured. Therefore, it is convenient for the short-circuit detector to accurately detect the battery cells.
