Description

Roll packing method of electromagnetic shielding gasket

The present invention relates to a roll packing method of a gasket for electromagnetic wave shielding, and relates to a roll packing method for an electromagnetic wave shielding gasket, characterized in that a sheet on which the gasket is disposed is packed in a roll type using a winding device.

In general, electromagnetic waves emitted from electronic and communication devices such as TVs, plasma display panels (PDPs), personal computers, etc. are known to adversely affect the human body by causing changes in body temperature and irregularities in circadian rhythms when exposed to the human body. .

In order to prevent such harmful effects, electromagnetic wave shielding gaskets are used on PCB circuit boards in electronic and communication devices, in the case of power noise generating units, or in areas with electromagnetic interference (EMI) of various electronic devices.

These gaskets are made by wrapping a fabric that conducts electricity in a urethane sponge, EPDM sponge, PE sponge, or silicone sponge to shield electromagnetic waves through grounding in various forms.

On the other hand, the above-described gasket is generally manufactured so that several gaskets can be attached to the sheet and used, and such a sheet-type gasket sheet is described in Patent Document 1 below as “Electromagnetic shielding conductive gasket sheet and manufacturing method thereof (Registered Patent of Korea) As in the publication No. 10-0852442), it is a conductive gasket sheet for electromagnetic wave shielding used in electronic and communication devices. A high-density polyurethane foam layer 10 having a plurality of through-holes made of copper (Cu), cobalt (Co), nickel (Ni), silver ( Ag), aluminum (Al), iron (Fe), and a conductive metal selected from the group consisting of gold (Au) is dry-deposited conductive metal layers (20, 20') to a thickness of 500 to 4000 Å; and the conductivity first plating layers 30 and 30' in which copper (Cu) is electrolytically plated to a thickness of 1-5 μm on the metal deposition layers 20 and 20'; and nickel (Ni), cobalt (Co), nickel (Ni)-cobalt (Co), or nickel (Ni)-iron (Fe)-cobalt (Co) in the first plating layers 30 and 30 ′ is 1 to It is manufactured including the second plating layer (40, 40') electrolytically or electrolessly plated to a thickness of 3㎛.

On the other hand, in the "conductive gasket sheet for electromagnetic wave shielding and manufacturing method thereof" of Patent Document 1, a worker manually removes or attaches a gasket on the sheet according to the manufacturing method, thereby reducing production efficiency, increasing labor costs, and in particular, manual work. There was a problem that negative effects such as deformation of the gasket, exposure of contaminants, and deterioration of adhesiveness and electrical properties may occur.

In addition, since the gasket is exposed on the sheet, the gasket may be arbitrarily deformed or damaged during storage or use, resulting in defective products.
