Continuous prismatic cell stacking system and method

摘要

A continuous prismatic cell stacking system and method are disclosed. The continuous prismatic cell stacking system, comprises: a frame; a conveyer belt; a plurality of air suction pans; at least three units for distributing separator including separator spool, positioning sensor of separator layer, upper roller of separator layer, lower roller of separator layer and cutter of separator layer; at least one unit for distributing cathode including cathode spool, positioning sensor of cathode layer, upper roller of cathode layer, lower roller of cathode layer, and cutter of cathode layer; and at least one unit for distributing anode including anode spool, positioning sensor of anode layer, upper roller of anode layer, lower roller of anode layer, and cutter of anode layer.

1. A method of forming a prismatic cell stack comprising a plurality of stacked prismatic cell layers comprising:
transporting an air suction pan along an inlet conveyor to a plurality of stacking stations; collecting one of the plurality of prismatic cell layers onto the air suction pan at each of the plurality of stacking stations to form the prismatic cell stack, wherein the prismatic cell layers collected onto the respective air suction pan for least some of the plurality of stacking stations comprises a stacking layer that is at least one of a separator layer, a cathode layer, or an anode layer,
wherein the collecting of the stacking layers for at least some of the plurality of stacking stations comprises:engaging a spool consisting of a continuous sheet of the respective separator layer, the cathode layer, or the anode layer;cutting the continuous sheet to form a cut portion of the stacking layer;engaging a plurality of rollers to push and place the cut portion of the stacking layer to pre-set positions; andengaging at least one position sensor to ensure that the cut portion of the stacking layer is aligned to the pre-set positions; andadhering the cut portion of the stacking layer onto the prismatic cell stack.
