Laminated battery cell production system

Abstract

The invention relates to a laminated battery cell production system, which comprises an anode conveying mechanism capable of providing an anode unit with a predetermined size; an isolating membrane packaging mechanism arranged at the downstream of the anode conveying mechanism and used for clamping the anode unit between isolating membranes; a laminating mechanism capable of connecting with the isolating membrane and laminating the isolating membrane; an electrostaticizing mechanism which is arranged at the upstream of the isolating membrane packaging mechanism and can enable the isolating membrane to be electrified so as to adsorb the anode unit; a cathode conveying mechanism which is arranged at the upstream of the laminating mechanism and can provide a cathode unit with a preset size; and a cathode compounding mechanism which is arranged at the downstream of the cathode conveying mechanism, wherein the isolating membrane can penetrate through the cathode compounding mechanism to thelaminating mechanism, and the cathode compounding mechanism is used for connecting the cathode unit to the surface, far away from the anode unit, of the isolating membrane. According to the laminatedbattery cell production system provided by the embodiment of the invention, the laminating precision and efficiency can be improved, the occupied area is small, and production and manufacturing of battery cells are facilitated.

[0003] In the traditional stacking equipment, the pole piece is first punched and shaped by the pole piece punching machine and installed on the material box, after filling a material box, the pole piece is transferred to the stacker, and the pole piece is stacked through the stacking platform. The stacking platform usually adopts a linear movement method to stack the pole pieces. Specifically, in the production process of the stacked cells, the stacking platform is first translated to the position where the positive pole piece is located, so as to stack the positive pole pieces. After the positive pole pieces are stacked, the lamination platform is moved to the position of the negative pole pieces in a straight line, and then the negative pole pieces are stacked. This kind of stacking method has defects such as low stacking efficiency and large floor space. It is not conducive to the production and manufacture of laminated cells
