In the multi-sheet lamination process, four groups of parallel pole piece groups are arranged in the horizontal direction after lamination is finished, and the diaphragms between the adjacent pole piece groups are in a continuous state, so that the diaphragms between the adjacent pole piece groups are cut off through a multi-sheet cutting and pole piece group manufacturing process, and independent pole piece groups are formed.
