The invention provides a
die cutting lamination
system and method. The
system comprises an unwinding mechanism, an
anode cutting mechanism, a preheating rolling device, a
cutting mechanism, a detection device and a lamination device, wherein the
anode cutting mechanism is matched with the
anode unwinding mechanism and cuts an anode sheet to obtain a lamination of the anode sheet relative to at least one of a first diaphragm, a second diaphragm and a
cathode sheet in
interval distribution; the rolling device enables at least two of the first diaphragm, the second diaphragm, the
cathode sheet and the anode sheet to be adhered to each other; the lamination is
cut by the cutting mechanism to obtain a core lamination unit and a
cathode lamination unit, or obtain the core lamination unit, the cathode lamination unit and a diaphragm lamination unit; the detection device detects whether the lamination unit has defects or not; the lamination device is used for laminating the lamination units. The
system has the advantages of the relatively simple structure, the high lamination speed, the low
failure rate, the small horizontal lamination space
occupancy rate, the convenient lamination cutting and the high cutting precision, and the negative influence of the diaphragm on the performances such as
internal resistance and specific capacity of the battery is small.
