Manual winding of magnetic ring inductor is a very careful manual work, how to better and more effective winding, which is also a problem worth thinking about by many manufacturers?

A, how about the manual winding technology of magnetic ring inductor?

With the continuous improvement of integrated inductance production and research and development technology, the price of integrated inductance will be lower and lower, I believe there will be more customers will choose integrated inductance.

Two, magnetic ring inductor manual winding technique?

If the number of turns is more, manufacturers need to prepare a plastic coil, to be large and thin, can open. First hang the wire reel on the magnetic ring, then wrap the enamelled wire around the wire reel, and fix it simply with tape to prevent it from falling out. Then the wire reel is wound to the magnetic ring, the wire reel also turns, each time the free part is wound, tear the tape, and remove a circle from the wire reel.

1, single-layer winding method

The so-called single-layer winding method is to wrap the coil turns in a single-layer way on the outer surface of the insulated pipe, the single-layer winding method can be divided into tight winding and indirect winding, indirect winding is generally used in some high-frequency resonant circuits, because this way of winding method can reduce the capacitance of the high-frequency resonance diagram, while also stabilizing some of its characteristics. The tight winding method is based on some coils with a relatively small resonant coil range.

The inductance of the coil is relatively large, and the winding method of the coil is a multi-layer winding method. The multi-layer winding method includes two types: honeycomb winding and dense winding. The dense winding method is arranged closely and needs to be distributed layer by layer, and the capacitance generated by the wound coil is relatively large. However, its capacitance is relatively small compared to the tight winding method.

Three, the winding process of magnetic ring inductor?

Coil winding manufacturing process is mainly divided into: winding, forming, sandblasting, gluing, coil full inspection, spot welding, etc. If the product is found to be poorly tested, it needs to be scrapped or reworked and repaired, packed and stored.

1. The specific production process and description of the winding inductor of the magnetic ring inductor are as follows:

1, magnetic ring inductor winding; Wind the copper wire to a fixed shape and size according to the requirements.

2, inductor coil dispensing; The surface of the integrated molding product is sprayed with corresponding paint according to customer requirements.

3, magnetic ring inductance inkjet; Spray print product labels on products according to customer requirements.

4, magnetic ring inductance bending foot; Use automatic equipment to cut off the excess material of the molded product, bend the end foot and stick flat on the surface of the product.

5, magnetic ring inductor test; Use equipment testing to test the electrical performance of products according to customer requirements.

6. Spot welding of integrated inductance coil; Weld the wound coil to the foot of the sheet using current fusion.

7, inductance coil forming; The spot-welded sheet is put into the mold and the iron powder is wrapped and stamped by a hydraulic punching machine.

8, coil sandblasting; The sand blasting machine uses glass sand blasting to punch the surface of the molded product.

9, coil external inspection; Detect if the appearance meets customer requirements.

10, coil braid; According to customer requirements, the qualified products are put into the woven carrier belt, which is easy to use by the end customer.

11, coil packaging; Put the woven carrier tray into the packing box to meet the transportation requirements and ensure that the product is not damaged.
