Description

Roll packing method of electromagnetic shielding gasket {Roll packing method of electromagnetic shielding gasket}

The present invention relates to a method for roll packing of a gasket for shielding electromagnetic waves, and relates to a roll packing method for a gasket for shielding electromagnetic waves, characterized in that the 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), and personal computers are known to have harmful effects on the human body by causing changes in body temperature and irregularities in biorhythms when exposed to the human body. .

In order to prevent such harmful effects, gaskets for shielding electromagnetic waves are used in PCB circuit boards in electronic and communication devices, cases of power noise generators, or parts with electromagnetic interference (EMI) of various electronic devices.

These gaskets shield electromagnetic waves through grounding in various forms, such as by wrapping fabric that conducts electricity around a urethane sponge, EPDM sponge, PE sponge, or silicon sponge.

On the other hand, it is common for the above-mentioned gasket to be manufactured so that several gaskets can be attached to a sheet and used, and such a sheet-type gasket sheet is described in Patent Document 1 below as “conductive gasket sheet for shielding electromagnetic waves and its manufacturing method (Republic of Korea Patent Publication No. 10-0852442)”, in the form of a conductive gasket sheet for shielding electromagnetic waves used in electronic and communication devices, with a specific gravity of 0.1 to 1.1 g/cm 3 and perforated at regular intervals on both sides. A high-density polyurethane foam layer 10 having a plurality of through holes, and copper (Cu), cobalt (Co), nickel (Ni), silver ( A conductive metal deposited layer (20, 20') in which a conductive metal selected from the group consisting of Ag), aluminum (Al), iron (Fe), and gold (Au) is dry-deposited to a thickness of 500 to 4000 Å; and the conductivity first plating layers 30 and 30' in which copper (Cu) is electrolytically plated on the metal deposition layers 20 and 20' to a thickness of 1 to 5 μm; and nickel (Ni), cobalt (Co), nickel (Ni)-cobalt (Co), or nickel (Ni)-iron (Fe)-cobalt (Co) in the first plating layer (30, 30') It is manufactured including second plating layers 40 and 40' electrolytically or non-electrolytically plated to a thickness of 3 μm.

On the other hand, the "conductive gasket sheet for shielding electromagnetic waves and its manufacturing method" in Patent Document 1 requires a worker to manually remove or attach a gasket on the sheet according to the manufacturing method, thereby reducing production efficiency, increasing labor costs, and especially, manual work There was a problem that negative effects such as deformation of the gasket, exposure of contaminants, and deterioration of adhesiveness and electrical characteristics may occur due to this.

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