Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic component manufacturing, in particular to a processing and assembling device for reactor coil and core. BACKGROUND

[0002] The reactor is also called inductor, which is widely used in circuit. Because of the existence of electromagnetic induction effect in the circuit, there is certain inductance, which can play a role in preventing current change. When a conductor is energized, a magnetic field will be generated in a certain space range occupied by the conductor. Therefore, all current-carrying conductors have inductance in general sense. The existing device needs to fix the core at a specified position and then sleeve the coil outside the top end of the core during the assembly of the coil and the core.

[0003] Three-phase ring reactor requires 120-degree winding to symmetrical magnetic field distribution, and the core is a closed ring. If manual winding is used without positioning tool, the coil may be crossed, overlapped or loose due to angle deviation or uneven tension. Too small tension during winding will cause the coil to be loose, and the wire cannot be pressed tightly during layer changing, which may cause winding crossing accident. Too large tension may damage the wire or destroy the insulation. On the other hand, the edge of the core column is not chamfered, the wire may slip and be incorrectly clamped during winding, and the concave-convex surface may cause uneven winding distribution, resulting in local accumulation and looseness.
