In a battery manufacturing process, it is necessary to use a material carrying mechanism to store a material such as an insulating membrane and an electrode sheet, to facilitate a pick-up mechanism to pick up the material.

It can be understood that a battery may be a battery cell, that is, the smallest electric energy storage unit formed by winding or stacking a positive electrode sheet, a negative electrode sheet and a separator; or may be a battery module, that is, an electric energy storage device formed by connecting and arranging a plurality of battery cells in series, parallel or series-parallel connection; or may be a battery pack, that is, an electric energy storage device formed by connecting and arranging a plurality of battery cells or a plurality of battery modules in series, parallel or series-parallel connection.
