Description

TECHNICAL FIELD [0001] The present invention relates to a magnetic field shielding sheet manufacturing apparatus and a manufacturing method thereof,

The present invention relates to a manufacturing apparatus and a manufacturing method of a magnetic shield sheet. More specifically, the magnetic plate body is formed with a plurality of through slits so as to be spaced apart from each other so that one magnetic plate body is not separated from the magnetic plate. It is possible to divide one magnetic plate body into a plurality of magnetic body portions without further processing, precisely control the position and shape of each magnetic body portion, and prevent loss due to eddy current in the magnetic plate body The present invention also relates to a manufacturing apparatus and a manufacturing method of a magnetic shield sheet which can prevent the permeability and the shielding performance from being deteriorated.

In general, various functions such as RFID, NFC, wireless charger, and pentell are added to mobile terminals such as mobile phones, tablet PCs and notebooks. Most of the additional functions of the portable terminal use a magnetic field ranging from several tens of kHz to several tens MHz. When exposed to a magnetic field of such frequency, various components built in a portable terminal such as a battery are affected.

Therefore, a magnetic shielding sheet is essentially used to prevent the portable terminal from affecting portable terminal components such as a battery due to the magnetic field used, and to improve the function of using the magnetic field by focusing the magnetic field.

However, since the magnetic plate that performs the shielding function in the conventional magnetic shield sheet is separated into fine pieces by a physical pressing force, it is disorderly arranged, and it is difficult to precisely control the position and shape of the gap.

In addition, since the magnetic plate that performs the shielding function in the conventional magnetic shield sheet is separated into fine pieces by the physical pressing force, the magnetic plates are separated from each other by the adhesive force between the fine pieces .

In addition, since a magnetic plate which performs a shielding function in a conventional magnetic shield sheet is separated into fine pieces by a physical pressing force, loss due to eddy current in the magnetic plate can be prevented, but due to a high clearance density But rather has a drawback that the permeability is reduced and consequently the shielding performance is lowered.
