Embodiment Construction

[0040] The following is attached Figure 1-3 The application is described in further detail.

[0041] The embodiment of the present application discloses a prefabrication process of a coil pin. The prefabrication process of the coil pins includes the following steps:

[0042] S1, prefabricated T buckle 1 and carrier tape 2:

[0043] refer to figure 1 and figure 2 , the metal sheet is put into the corresponding blanking die, and the carrier tape 2 is punched out. The carrier tape 2 consists of a plurality of supporting frames 21 spliced ​​with each other, two connecting bars 22 arranged in each supporting frame 21 and It is used to connect two connecting bars 22 and an extension piece 23 on the inner side wall of the support frame 21. The support frame 21 is composed of two positioning bars that are parallel to each other and set opposite to each other, and are erected between the two positioning bars and are used to separate adjacent ones. The support strips of the two e...

Abstract

The invention relates to a prefabrication process of a coil pin, which comprises the process steps of prefabricating a T buckle and a carrier tape, assembling, blanking and welding, performing powder hot press molding, cutting and molding, performing insulation treatment and performing contact electroplating. A coil sleeves a middle column on the T buckle, and the T buckle with the coil and the carrier tape are integrally assembled; the length of a coil pin is shorn to a certain length, the coil pin is welded and fixed to a connecting strip on a carrier tape, meanwhile, the connecting strip, a T buckle and the coil are wrapped in a formed inductor body through the integrated hot-press forming technology, one side face of the connecting strip is exposed out of the inductor body to serve as a contact of the inductor, and then the connection part of the carrier tape and the inductor body is cut off, the surface of the inductor body except the contact area is subjected to insulation treatment, and the contact area is subjected to electroplating treatment. The process has the advantages that the coil pins do not need to be bent, the inductor cracking phenomenon caused by the bending procedure can be avoided, and the effect of improving the inductor yield is achieved.

Description

technical field [0001] The present application relates to the field of inductor manufacturing technology and equipment, in particular to a prefabrication process of coil pins. Background technique [0002] Inductors, also known as inductors or inductance coils, are one of the basic components that make up electronic circuits. The inductor structure mainly includes an inductor body, a coil wrapped inside the inductor body, and two coil pins fixedly connected to the coil and extending to the outside of the inductor body. [0003] In the existing inductor production process, most of the coil pins are first pressed into a flat shape, and then a certain amount of metal powder is added to the cavity of the powder molding mold, and then the coil is placed in the cavity and the metal is added again. The powder covers the coil, and after the powder is pressed and formed to form an inductor, the coil pins are bent several times so that the flat pins of the coil fit on the outer surfa...
