The invention relates to a fine vertically wound enamelled copper flat wire and its manufacturing equipment and manufacturing process, which is especially suitable for three-dimensional winding coils and belongs to the technical field of electrical machinery and equipment manufacturing in the wire and cable industry. The fine vertically wound enamelled copper flat wire includes a metal conductor core and an insulating varnish layer covering the outside of the metal conductor core. Including the following manufacturing processes: 1), cleaning, drying, calendering; 2), cleaning, drying, softening; 3), cleaning, drying, cooling; 4), painting, baking, oiling. The invention can prevent impurities and dust from being pressed into the surface of the copper flat wire, can completely remove the impurities and dust generated in the bare copper flat wire after trimming the flat wire drawing die to specifications, and solves the problem of the paint film on the product affected by the impurities and dust on the surface of the copper wire Adhesion issues.
