Bag-making type stacking apparatus and stacked product

Abstract

The present application relates to the technical field of battery production configuration, in particular to a bag-making type stacking apparatus and a stacked product. The bag-making type stacking apparatus comprises: a negative electrode bag-making system, comprising a negative electrode plate plate-making system (1) and a unit plate composite bag-making system (2) which are arranged in a spaced manner; a positive electrode plate plate-making system (3) spaced apart from the negative electrode bag-making system; a stacking device (4) spaced apart from the negative electrode bag-making system and the positive electrode plate plate-making system (3); and a carrying device (5) spaced apart from the stacking device (4), the carrying device (5) is provided with a carrying member which reciprocates between the unit plate composite bag-making system (2), the stacking device (4) and the positive electrode plate plate-making system (3). The bag-making type stacking apparatus can stack a plurality of unit plates (100) and a plurality of positive electrode plates (200) in one instance, thereby greatly improving the stacking speed, and improving the production efficiency; and importantly, the tension change amplitude of a diaphragm is small, and the diaphragm is always kept in a properly tensioned state, thereby avoiding wrinkles during stacking, prolonging the cycle life of a battery, avoiding thermal runaway caused by diaphragm contraction, and ensuring safety of the battery.
