Description

Square electric core stacks extrusion device Technical Field The utility model relates to the field of battery cell production, in particular to a square battery cell stacking and extruding device. Background In the process of stacking and extruding the production modules, the accurate positioning and stable extrusion of the battery cells are vital links. However, conventional production methods rely mainly on manual operations in this link, which brings about various challenges and disadvantages. First, it is difficult to ensure the stacking accuracy and consistency by manually stacking the cells. Due to the difference of skill level and physical state of operators, the battery cells often have the problems of offset, dislocation and the like in the stacking process, which not only affects the orderly arrangement of the battery cells, but also can cause uneven stress in the subsequent extrusion process, thereby affecting the quality of products.
