3) Stacking pole pieces: a piece feeding assembly is respectively arranged in front of and behind the center of the lamination (7), positive and negative pieces are pressed on two sides of a diaphragm on the lamination position at the same time, after the pressure is released, a pair of pressing knives (402) of the left winding head (1) are rotated by 90 degrees clockwise by a motor (601) for moving the pair of pressing knives (402) to move away from the center of the lamination (7), meanwhile, a pair of pressing knives (402) of the right winding head (2) do the same action, are far away from the center of the lamination (7) after the pressure is released, move towards the lamination position after the respective movement distance is in place, and clamp the diaphragm and pole piece assembly after the movement is in place;
4) Winding: the motor (501) for rotating the left winding head (1) drives the pressing knife (402) to rotate 180 degrees clockwise, the motor (501) for rotating the right winding head (2) drives the pressing knife (402) to rotate 180 degrees anticlockwise, the diaphragm pole piece assembly is driven to rotate, and the diaphragm is wound on the outer sides of the positive pole piece and the negative pole piece;
5) The cycle is then completed until the laminated pole pieces reach a certain thickness to complete lamination (7).
