Abstract

The invention discloses a battery cell discharging device and method. The battery cell discharging device comprises a stretching mechanism and a flattening mechanism. The stretching mechanism is used for clamping the upper end and the lower end of a battery cell in the vertical direction and enabling the upper end and the lower end of the battery cell to move in the direction away from each other so as to stretch the battery cell. The flattening mechanism is used for receiving the stretched battery cell and flattening the battery cell in the thickness direction of the battery cell. According to the battery cell discharging device and method, the battery cell is stretched in the vertical direction, so that an inner-layer pole piece and a diaphragm of the battery cell are in a vertical state when a winding needle mechanism is pulled out, and the inner-layer pole piece and the diaphragm of the battery cell cannot droop due to the influence of self gravity; and compared with the manner of horizontally stretching the battery cell, redundancy of the pole piece and the diaphragm at corners is easily eliminated during flattening, the corners of the battery cell are not prone to wrinkling, and therefore the quality of the battery cell can be improved.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a cell blanking device and a cell blanking method. Background technique [0002] After the battery core is wound, the battery core needs to be loaded and unloaded from the needle winding mechanism. Existing cell blanking methods (such as figure 1 As shown) two sets of clamping rods are used to clamp the left and right ends of the battery cell respectively, and then the needle rolling mechanism is pulled out from the battery core, and then the two sets of clamping rods are used in the horizontal direction ( figure 1 The battery core is stretched by moving opposite to each other in the left and right directions, and then the middle part of the battery core is preloaded from top to bottom with a pressure rod. Using the above cell blanking method, when the needle winding mechanism is pulled out from the cell, the heads of the anode pole piece b and the cathode pole pi...
