Description

Technical Field

[0001] The utility model relates to the technical field of transformer winding, in particular to an automatic winding device for an electronic transformer. Background Art

[0002] An electronic transformer is an electronic device that converts the alternating voltage of the mains electricity into direct current (DC), which is then converted into a high-frequency AC voltage output through semiconductor switching devices, electronic components, and high-frequency transformer windings. It is also a type of AC-DC-AC inverter circuit described in electronics theory. It primarily consists of a high-frequency transformer core (iron core) and two or more coils, which do not change position with each other. They convert AC power from one or more electrical circuits into AC voltage and current through electromagnetic induction. Current automatic winding devices for electronic transformers typically secure the core bobbin to a rotating device, which rotates the core bobbin to wind the enameled wire. However, during the winding process, the wire exit angle on the wire roller is fixed for a short period of time, which can easily cause the enameled wire wrapped around the core bobbin to accumulate, affecting the quality of the final product.
