The transition over roller 31 is used for conveying the diaphragm and winding the diaphragm on the plurality of roller bodies 32 in sequence, and conveying the diaphragm to the lamination platform. It should be noted that the diaphragm roll 40 on the unwinding roller 21 is unwound, and the diaphragm is conveyed through the transition over roller 31 and the plurality of roller bodies 32 during the conveying process. The number of roller bodies 32 can be determined according to actual needs, such as 3, 4, 5, etc. In the present embodiment, a second driving member is arranged for driving the transition over roller 31 and the plurality of roller bodies 32 to rotate, and the second driving member is fixed on the rack 10. In the present embodiment, the second driving member is a motor.

[0025] Further, referring to Figure 1The rack 10 is provided with a tension swing roller 50 for adjusting the tension of the diaphragm. The tension swing roller 50 is located on one side of the transition roller 31. The diaphragm roll 40 is unwound from the transition roller 31 after being unwound from the unwinding roller 21, and then wound on the tension swing roller 50, and then transmitted to the laminated platform through a plurality of roller bodies 32. It should be noted that the tension swing roller 50 is used to adjust the tension of the diaphragm, so as to avoid the mismatch between the unwinding speed of the diaphragm and the use speed of the diaphragm in the laminated plate, so as to avoid the change of the tension of the diaphragm and the tearing of the diaphragm.

[0026] With reference to Figure 1 and Figure 2 , the transition roller 31 is provided with a foolproof plate 60. One side of the foolproof plate 60 is fixed to the rack 10. The foolproof plate 60 is used for the foolproof operation of the diaphragm unwinding anti-wrong structure. The transition roller 31 is provided with a frame body 70 for fixing the transition roller 31. The frame body 70 is arranged in an inverted C shape. One side of the frame body 70 is arranged in an opening. The transition roller 31 is rotatably arranged in the opening of the frame body 70. One end of the frame body 70 is fixed to the rack 10, so that the transition roller 31 is rotatably arranged on the rack 10.

[0027] With reference to Figure 2 , the foolproof plate 60 is located below the frame body 70. The foolproof plate 60 is used to prevent the diaphragm from being passed from below the transition roller 31 when the diaphragm is replaced. The foolproof plate 60 is arranged in an F shape. The foolproof plate 60 is provided with two first parts 61 and second parts 62 arranged transversely. Specifically, the frame body 70 is provided with a slot 71 along the length direction.
