Description

Apparatus for manufacturing choke coil

The present invention relates to a choke coil manufacturing apparatus, and more particularly, to a choke coil manufacturing apparatus capable of mass-producing a spiral wound choke coil including a core.

In general, the choke coil is a coil component for obtaining inductance, and serves to block current of a relatively high frequency and pass only a current of DC or relatively low frequency. The choke coil is divided into an iron core choke coil having a ferromagnetic iron core and an air core choke coil made by winding a coil around a frame of other nonmagnetic materials such as fiber and plastic without having a ferromagnetic iron core.

There are several methods for producing the iron core choke coil mentioned above, but the method is to wind the coil around the core and fix it with a binder, and after producing the coil and the core, apply a binder to the core and apply it to the inside of the coil. It is manufactured through the method of inserting and bonding the core.

When manufacturing the iron core choke coil as described above, the process of winding the coil on the core or applying the binder to the core, and inserting the core into the coil are all manually performed by the worker, resulting in poor productivity and high defect rate. there was.

A technique for solving this is published in Korean Patent Registration No. 10-1400458 (hereinafter referred to as 'citation invention'). Cited invention relates to a choke coil production apparatus that is configured to be inserted into a coil while applying a binder to the core and rotating, so that the binder is adhered to the coil while coated on the outer surface of the core.

The above cited invention is only an automatic process of bonding a core with a binder to a coil wound in a spiral shape during the entire process of producing the choke coil, and although it is possible to improve a little productivity, the rest of the process has to be performed manually, so it is still There is a problem that it is not suitable for mass production.
