AI Technical Summary
In existing inductor winding devices, the wires are prone to overlap or the spacing between wires changes during the winding process, resulting in unstable product quality. This problem is particularly prominent when the surface roughness of the magnetic core is uneven or the wire diameter is small.
An inductor coil winding device was designed, which uses a feeding assembly including a mandrel, a push ring, a connecting sleeve, and a clamp. The mandrel is driven to rotate by a winding motor and the push ring moves along the magnetic core axis to ensure that the wire is wound evenly on the magnetic core surface. The thread is used to match the wire diameter and the wire spacing to stabilize the winding process.
This method enables the wires to be wound uniformly on the surface of the magnetic core, improving the quality of the finished product, ensuring the stability and consistency of the wiring, and enhancing the overall performance of the inductor coil.
