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.
