Laminated coil and manufacturing method therefor

A manufacturing method of a laminated coil comprising following steps:

• S1. laminated unit procedure, which comprising processing on a base plate to form a base body including a plurality of laminated units, and reserving a connection unit at both ends of the base body;
• wherein each laminated unit of the plurality of laminated units comprises an opening, a first common edge and a second common edge, wherein opening directions of two adjacent laminated units are opposite, and the laminated unit is separately jointed with two adjacent laminated units by means of the first common edge and the second common edge;
• S2. folding and lamination procedure, which comprising folding the base body along the first common edge and the second common edge of the laminated unit to form a middleware with laminated units laminated successively;
• S3. molding procedure, which comprising molding the middleware according to a preset structure, and reserving an insulation layer interval in the middleware;
• and
• S4. insulation procedure, which comprising adding an insulation layer into the insulation layer interval in the middleware, and wrapping the insulation layer on the base body.

A manufacturing method of a laminated coil comprising following steps:

• S1. folding procedure, which comprising folding a base plate and reserving a connection unit at both ends of the base plate to form a first middleware in a laminated state;
• S2. laminated unit procedure, which comprising processing on the first middleware in a laminated state to form a base body with a plurality of hollow laminated units having an opening, wherein opening directions of two adjacent laminated units are opposite, and each laminated unit of the plurality of hollow laminated units is separately jointed with two adjacent laminated units by means of the first common edge and the second common edge to form a second middleware with laminated units laminated successively;
• S3. molding procedure, which comprising molding the second middleware according to a preset structure, and reserving an insulation layer interval in the second middleware;
• and
• S4. insulation procedure, which comprising adding an insulation layer into the insulation layer interval in the second middleware, and wrapping the insulation layer on the base body.
