Cell stacking device

Abstract

The present application discloses a cell stacking device, including: a stacking assembly and a swing assembly; the stacking assembly includes: a stacking table, the stacking table has a working surface and a side, and the side includes a first side and a second side; The swing assembly includes: a swing arm shaft, which is fixed above the working surface and can rotate around the first axis; an intermediate piece connected to the swing arm shaft at one end; a guide mechanism connected to the other end of the intermediate piece, including: a first guide piece and a second guide piece. The guide piece, the pole piece belt is located in the gap between the first guide piece and the second guide piece; the support piece is arranged obliquely relative to the guide piece; the swing arm shaft rotates around the first axis, and the support piece can be connected with the first side, the second The two sides are in contact, and the pole strip can be laid on the working surface along a laying direction perpendicular to the first axis direction. In the present application, the Z-shaped guide of the pole piece belt can be realized through the rotational movement of the swing assembly, thereby effectively improving the production efficiency of the electric core.

Description

technical field [0001] The invention relates to the technical field of lithium-ion batteries, in particular to a cell stacking device. Background technique [0002] Lithium-ion batteries usually use laminated cells: the separator is folded in a "Z shape", and then the positive and negative pole pieces are inserted. This type of cell usually requires about 50-60 layers of laminations (or even more). At present, the "Z-type lamination method" is often used, and the lamination table moves to the left and right to drive the diaphragm to fold. The moving distance required for the stacking table to move to the left and right is too long, resulting in a longer cycle of completion of the battery cells, which cannot meet the existing production needs. [0003] In addition, in the actual production process, in order to increase the lamination speed, many equipments are equipped with lamination stations, which makes the equipment bulky. Each stacking station is used to stack one bat...

Problems solved by technology

The moving distance required for the stacking table to move to the left and right is too long, resulting in a longer cycle of completion of the battery cells, which cannot meet the existing production needs

[0003] In addition, in the actual production process, in order to increase the lamination speed, many equipments are equipped with lamination stations, which makes the equipment bulky

Each stacking station is used to stack one battery cell. After the stacking of a single station is completed, it needs to be shut down, and then the battery cell is taken out from the station for the blanking process, so that the subsequent stacking of the battery cell can be carried out, which affects the stacking process. chip efficiency
