Laminated cell dismantling equipment and dismantling method

Abstract

The invention relates to a dismantling equipment and method for laminated battery cells. The dismantling equipment for laminated battery cells includes: a battery cell placement platform for positioning and placing laminated battery cells to be disassembled; a diaphragm winding mechanism including The reel, which is arranged above the cell placement platform and can rotate around its own axis, unfolds the folded diaphragms in the laminated cells sequentially by winding the diaphragm; The core is placed between the platform and the positive electrode plate receiving area, so that the positive electrode plate on the diaphragm can be absorbed and dismantled during the expansion process of the diaphragm and transferred to the positive electrode plate receiving area; The core is placed between the platform and the negative electrode sheet receiving area, so that the negative electrode sheet on the diaphragm can be adsorbed and disassembled during the diaphragm expansion process and transferred to the negative electrode sheet receiving area; the positive electrode sheet suction cup transfer mechanism and the negative electrode sheet suction cup transfer mechanism , which is used to absorb the corresponding pole piece with the suction cup assembly.

Description

technical field [0001] The invention relates to a dismantling device and a dismantling method for laminated electric cores. Background technique [0002] In the manufacturing process of lithium-ion laminated cells, due to the lack of positioning function of the positioning platform, the error of the equipment itself, etc., the positions of the pole pieces will be shifted, resulting in the positive and negative pole pieces of the stacked cells not in the specified position. Therefore, it is necessary to disassemble the unqualified laminated cells. [0003] In the prior art, the laminated cells are generally disassembled manually. When dismantling, the operator needs to lift the diaphragm with one hand and dismantle the pole piece with the other hand, and the disassembly efficiency is low; at the same time, during manual disassembly, the pole piece is lifted from the side of the pole piece to remove the pole piece from the diaphragm If the pole piece is disassembled from the...
