[0039] It is worth noting that the material preparation mechanism 2 clamps the plate stack 102 laterally according to its height and then pushes the material forward as a whole to avoid misalignment of the upper plate 101 of the plate stack 102 due to inertia during the pushing process. This embodiment can effectively achieve stable material replenishment of the plate stack 102.

[0040] As a preference, Figure 3As shown, the material preparation mechanism 2 is arranged to move forward and backward to push the plate stack 102 for replenishment or return it to its original position.

[0042] During operation, the material preparation mechanism 2 loads the spare group of pole plate stacks 102 when the two material preparation bin plates 21 are in a folded state. In the folded state, the width dimension of the material preparation bin 20 is adapted to the left and right width dimensions of the pole plate 101, so that the left and right sides of the spare group of pole plate stacks 102 can be limited and aligned, and the front and rear sides of the pole plate stack 102 are shaped and aligned under the cooperation of the pushing part 22 and the clamping part 11 when the replenishment material is pushed into place.

[0043] As a preference, Figure 2 As shown, a material pushing portion 22 is protruding from the inner wall of the material preparation bin plate 21 , and the rear side of the electrode stack 102 abuts against the material pushing portion 22 so as to be pushed forward by the material pushing portion 22 .

[0044] Preferably, a clamping portion 11 is provided at one end of the hopper mechanism 1 away from the material preparation mechanism 2 , and the clamping portion 11 cooperates with the pushing portion 22 to limit the end point of the replenishment pushing of the plate stack 102 and to shape and align the front and rear sides of the plate stack 102 .

[0051] Taking the case where two stock bins 20 are provided, as a preferred embodiment, Figure 4 As shown, the side of the material pushing portion 22 facing the material preparation bin 201 is set as a material pushing plane 221 parallel to the rear side of the electrode stack 102;
