Description

Technical Field

[0001] This utility model relates to the technical field of electronic component manufacturing, and in particular to a needle winding mechanism for a foot winding machine. Background Technology

[0002] In the production of electronic products such as filters and transformers, a magnetic ring (also known as a coil) needs to be placed inside the housing. The copper wire on the magnetic ring is then wound onto pins on both sides of the housing for subsequent processing. Conventional pin winding uses a semi-automatic structure. A vision system or manual operation aligns the winding pin with the pin position on the winding jig, and the copper wire on both sides of the magnetic ring is connected to the housing by winding the copper wire. However, when different pin positions on the same housing require winding copper wire of different thicknesses, different winding pins must be used, which is inconvenient and results in low production efficiency.
