[0002] In recent years, the state has strongly encouraged and supported the development of new energy technologies. The demand for new energy power batteries from many manufacturers has increased significantly, which brings great development opportunities to power battery manufacturers.

[0003] Lithium secondary battery packs with high energy density, high operating voltage, good storage characteristics and life characteristics are widely used as energy sources for various types of mobile devices and various electronic products. During the processing of power battery modules, generally several battery cells (power battery blocks) need to be stacked into cell modules with different volumes and power according to actual needs. The stacking of batteries is completed on a stacking platform. The existing stacking platform adopts single-station stacking, and the waiting time for loading and unloading during stacking is relatively long, resulting in low stacking efficiency. Another defect is that the battery positioning frame on the stacking platform is fixedly arranged and cannot be adjusted according to the size of the battery, so the adaptability is relatively low.
