COMPOUNDING DEVICE AND LAMINATION MACHINE

The present application relates to a composite device, including a first electrode material strip unwinding mechanism, a crease mechanism, and a first composite mechanism; the first electrode material strip unwinding mechanism is configured to unwind the first electrode material strip; the crease mechanism is disposed downstream of the first electrode material strip unwinding mechanism and is configured to form a plurality of creases spaced apart along a length direction of a first electrode material strip and extending along a width direction of the first electrode material strip on the first electrode material strip in a path; and the first composite mechanism is disposed downstream of the crease mechanism and is configured to combine a first diaphragm, a second diaphragm, and the first electrode material strip, so as to stack the first diaphragm, the second diaphragm, and the first electrode material strip in sequence to form a first composite material strip. By arranging the above composite device, during a process of folding the first composite material strip, it may be directly folded along the creases. The composite device uses belt-shaped pole sheets directly without cutting, which effectively improves efficiency of subsequent lamination. The present application also relates to a laminating machine.
