Group 14, the movable mounting frame 11 is installed above the frame, a lamination table 61 is installed below the diaphragm roller moving group 14, and the diaphragm roller moving group 14 includes two guide rollers 141 arranged spaced apart from each other, and between the two guide rollers 141 A guide channel 142 is formed, the diaphragm unwinding device 20 unwinds a diaphragm M1 into the guide channel 142 , the diaphragm roller moving group 14 is installed on the output end of the moving driver 12 , and the moving driver 12 drives the diaphragm roller moving group 14 on the moving mounting frame 11 . The two guide rollers 141 for translational simple harmonic motion drive the diaphragm M1 in the guide channel 142 to be stacked back and forth on the lamination table 61, and the pole pieces are loaded. The device 13 alternately places the positive electrode sheet J1 and the negative electrode sheet J2 on the diaphragm M1 on the lamination table 61, and the cell reclaiming device 30 takes off the laminated cell to the end winding device 40, and the end winding device 40 pairs After finishing the battery cells, they are sent to the glue sticking device 50 for sticking. Therefore, in the battery stacker 100 of the present invention, the diaphragm roller moving group 14 performs a translational simple harmonic motion on the moving mounting frame 11, so as to make it wear on the battery stacker 100. The diaphragm M1 in the guide channel 142 performs a translational back-and-forth movement of the lower film, and the diaphragm M1 is folded back and forth and placed on the lamination table 61, so the swinging film lowering method is avoided, which effectively improves the production efficiency and realizes the movement of the diaphragm roller. The translational movement of the group 14 is simpler than the transmission structure required to realize the swinging movement, so the battery stacker 100 of the present invention also has the advantage of a simple structure.

The above disclosures are only preferred examples of the present invention, and cannot limit the scope of the rights of the present invention. Therefore, the equivalent changes made according to the claims of the present invention all belong to the scope covered by the present invention.
