Nanocrystalline soft magnetic composite device, nanocrystalline soft magnetic composite process and multilayer nanocrystalline soft magnetic structure

The invention relates to the technical field of nanocrystalline magnetic thin film manufacturing, in particular to a nanocrystalline soft magnetic composite device and process and a multi-layer nanocrystalline soft magnetic structure. According to the key points of the technical scheme, the device comprises a rack and further comprises an unwinding mechanism used for unwinding an adhesive layer, a protective layer and a soft magnetic layer; the first pressing mechanism is located at the downstream of the unwinding mechanism and used for pressing and pasting the soft magnetic layer and the adhesive layer; the second pressing mechanism is located at the downstream of the first pressing mechanism and used for pressing and attaching the protective layer to the side, back to the adhesive layer, of the soft magnetic layer so as to form a semi-finished product; the die cutting mechanism is located at the downstream of the second pressing mechanism and used for conducting die cutting on the adhesive layer, the protec
