Its core functions include accurate delivery, positioning, winding and blanking of wire. Specifically, the equipment clamps wire by rubber wheel and drives it to feed uniformly, then the wire enters the wire slot inside the mold, and forms a ring-shaped coil after bending through arc structure. The equipment is widely used in electronic component manufacturing field, and is an indispensable key equipment in the production of precision electronic components such as resistors and inductors. Although the traditional winding machine can realize basic winding function, it still relies on manual operation in the blanking link, and it is urgent to improve the automation level and production efficiency through technical innovation.
