A common mode inductor winding method and its equipment

Abstract

The invention discloses a common-mode inductance winding method and its equipment. In the method, the starting end of the enameled wire is fixed at the pre-clamping device, which solves the hidden danger of the wire head flying in the winding process, and uses a tensioner to adjust the tension of the enameled wire. The size to the tight state avoids the problems of loose wire winding and easy detachment of pad hanging wires. The use of tensioner also avoids the occurrence of wire breakage caused by excessive tension. The position of the wire hanging on the plate effectively reduces the difficulty of adjusting the position of the wire hanging on the pad, and the threading column is fixed on the fixture, which also avoids the problem of inconsistent positions of the enameled wire when different fixtures hang the wire to the pad. The invention can make the wiring The wire-hanging position of the path and pad is intuitive and easy to adjust, which solves the problem of difficult wire-hanging. It not only improves the winding efficiency and stability, but also improves the production efficiency and product qualification rate, reduces the cost, and makes the magnetic of the common mode inductor The winding effect of the core is easy to adjust.

Description

technical field [0001] The present invention relates to the technical field of common-mode inductors, and more specifically, relates to a common-mode inductor winding method and equipment thereof. Background technique [0002] Common mode inductors, also known as common mode chokes or common mode filters, are used for common mode noise suppression, suitable for digital product signal lines, automotive fields, industrial control product signal lines, power lines and various communication equipment. At present, the winding method of common mode inductors on the market is relatively single. The traditional manual winding of common mode inductors is low in accuracy, time-consuming and labor-intensive, and largely dependent on labor, with low yield, low efficiency, and high cost. In the wiring process, it is easy to scratch the enameled film of the copper wire, causing poor voltage resistance, and it is easy to have more or less windings, resulting in poor number of turns, result...

At present, the winding method of common mode inductors on the market is relatively single. The traditional manual winding of common mode inductors is low in accuracy, time-consuming and labor-intensive, and largely dependent on labor, with low yield, low efficiency, and high cost. In the wiring process, it is easy to scratch the enameled film of the copper wire, causing poor voltage resistance, and it is easy to have more or less windings, resulting in poor number of turns, resulting in poor consistency of product characteristics, and even product NG. Uneven distribution will also affect high-frequency characteristics, resulting in insufficient margin for high-frequency parameters
