Phase position-distinguishing manufacturing method for inductor

Abstract

The invention relates to the technical field of electronic elements, and particularly discloses a phase position-distinguishing manufacturing method for an inductor. The method comprise the steps of winding: utilizing and winding copper wires into spring-like hollow coils; phase position distinguishing: providing a material piece, and shearing an oblique angle at the end part of the frame of one side of the material piece for phase position distinguishing; spot-welding: spot-welding multiple coils onto a material piece along the same winding direction, and electrically connecting each coil with two electrode pins on the material piece; cutting line heads; molding: forming a magnetic solid body molded by a metal magnetic powder material outside each coil, and extending the two electrode pins along the two end parts of each magnetic solid body; baking: baking in an oven of 80-160 DEG C; character printing; bending pins: bending the electrode pins of each magnetic solid body to enable the electrode pins to be tightly attached to the face of the magnetic solid body; testing: using a test instrument for testing and judging good and inferior products; and appearance checking and packaging. The phase position-distinguishing manufacture method for the inductor is simple in manufacturing process, easy for performing phase distinguishing and convenient for pasting on a board in the later period.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to a manufacturing method of an inductor. Background technique [0002] Inductors, also known as inductance coils, are one of the basic components of electronic circuits. According to the phenomenon of electromagnetic induction, as long as the magnetic flux passing through the coil changes, the electromotive force will be induced in the coil, and when the magnetic flux changes due to the change of the current in a coil, not only the induced electromotive force will be generated in the county weight, but also the electromotive force will be induced. Induced electromotive force may also be generated in other adjacent coils, which leads to the problem of judging the homonym of the mutual induction coil. [0003] Distinguishing the homonym of the mutual inductance coil is not only necessary in theoretical analysis, but also very important in practical application. Becaus...

Problems solved by technology

However, in the prior art, in the production process of inductors, not only the process flow is relatively cumbersome, but also there is no phase distinction for inductors, and there is no effective method for distinguishing coil phases, and only experienced technicians can judge visually The polarity of the outgoing coil

This operation method of relying on visual identification of the polarity of the coil not only requires high experience of the staff, but also has low work efficiency, which is not conducive to industrialized mass production.

During this process, if the polarity judgment is wrong, the coil cannot be put into the subsequent processing fixture

Furthermore, since the inductors are not polarized during the production process, it is not convenient for post-board use
