[0051] As Figure 2 shown, as a further solution of the present utility model: further includes a first limiting member 220 and a second limiting member 230 for limiting the transfer mechanism 900.

[0052] The first limiting member 220 and the second limiting member 230 are used to limit the running stroke of the transfer block 210.

[0053] Working principle: The first foil 510 and the second foil 520 are laminated into the laminated foil 500 by the lamination mechanism 400. The linear drive device is set according to the required length of each section of the laminated foil 500 after cutting, and the first limiting member 220 and the second limiting member 230 are used to limit the running stroke of the transfer block 210, so that the stroke of the transfer block 210 is equal to the required length of each section of the laminated foil 500 after cutting. The first cylinder 300 is deflated, so that the upper cylinder connecting member 310 and the lower cylinder connecting member 320 move closer to the middle, and then drive the upper clamp connecting member 330 and the lower clamp connecting member 340 respectively to move closer to the middle. The upper clamp connecting member 330 and the lower clamp connecting member 340 drive the upper clamp 350 and the lower clamp 360 respectively to move closer to the middle, so as to clamp the laminated foil 500. Then, as the transfer block 210 moves, the connecting member 930, the support member 910 and the first cylinder 300 are transferred, and the upper clamp connecting member 330 and the lower clamp connecting member 340 are indirectly transferred to transfer the laminated foil 500 to the cutting position. Then, the second cylinder 600 and the third cylinder 700 are inflated. As the second piston 610 and the third piston 710 extend outward, the upper cutting knife 810 and the lower cutting knife 820 move closer to the middle to cut the laminated foil 500. Then, the first cylinder 300 is inflated, indirectly causing the upper clamp 350 and the lower clamp 360 to move away from each other to release the laminated foil 500. Finally, the transfer block 210 moves back, indirectly driving the upper clamp 350 and the lower clamp 360 to return to their original positions, and then the first cylinder 300 is deflated for repeated operations to cut the laminated foil 500.

[0054] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention without departing from the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
