Winding method for integrated magnetic component winding

Abstract

The invention discloses a winding method for an integrated magnetic component winding, comprising placing a transformer skeleton, an inductor skeleton and wires at corresponding positions of an automatic winding machine; rotating the transformer skeleton to wind a first group of wires around the transformer skeleton to form a part of a secondary coil, and not cutting off a lead-out end; rotating the inductor skeleton to wind a second group of wires around the inductor skeleton to form an inductor winding, and not cutting off a lead-out end; successively engaging the wire at the lead-out end ofthe inductor winding with a wire duct at the other end of the inductor skeleton and a wire duct at the other end of the transformer skeleton, simultaneously rotating the transformer skeleton and theinductor skeleton in the same direction in order to wind the second group of wires around a part of the secondary coil to form a primary coil, introducing the lead-out end into the wire duct and thencutting off the lead-out end; using the lead-out end of a part of the secondary coil as the starting end of the other part of the secondary coil, and simultaneously rotating the transformer bobbin andthe inductor bobbin in the same direction in order to winding the first group of wires around the primary coil to form the other part of the secondary coil, introducing the lead-out end into the wireduct and then cutting off the lead-out end.

Description

technical field [0001] The invention relates to magnetic components, in particular to a winding method for integrated magnetic components. Background technique [0002] Magnetic components are widely used in new energy vehicles, photovoltaic / wind power generation, power harmonic control, inverters, electronic information, UPS, PC and other fields. As one of the core devices, the magnetic component has parameters such as its size that directly affect the product quality. With the change of the use environment and different application fields, the performance of the components will also vary greatly. Especially in the field of new energy vehicles, the requirements for component volume, weight and application environment are extremely high. Therefore, it is imperative to develop a high-power-density, highly-integrated vehicle-mounted magnetic component. At present, when making magnetic components integrated with transformers and inductors, the traditional winding method is m...
