Abstract

The invention discloses a lamination method for manufacturing electric cores and electric core pole group manufacturing equipment. The lamination method includes arranging a first diaphragm and a second diaphragm opposite to each other, and inserting positive plates into the first diaphragm and the second diaphragm one by one. between them, and alternately set the negative electrode sheets on the side of the first diaphragm facing away from the second diaphragm and on the side of the second diaphragm facing away from the first diaphragm. According to the stacking method of the present invention, two diaphragms can be stacked at the same time, which shortens the manufacturing time of the battery pole group, improves the manufacturing efficiency of the battery pole group, and thus improves the battery manufacturing efficiency.

Description

technical field [0001] The invention relates to the field of vehicle manufacturing, in particular, to a lamination method for manufacturing electric cores and equipment for manufacturing electric core pole groups. Background technique [0002] In related technologies, with the development of new energy machinery such as new energy vehicles, the application of batteries is becoming more and more extensive. In the field of lithium batteries and other batteries, z-shaped lamination technology is usually used when manufacturing the electrode group of the battery cell, that is, when laminating, the negative electrode sheet is stacked first, then the negative electrode sheet is coated with a separator, and then the positive electrode sheet is stacked. Wrap the separator around the positive electrode. The lamination unit of this lamination method is a single pole piece or a single diaphragm, and the speed of using this lamination method is slow, resulting in low efficiency of cell...
