Description

전자파차폐용 용접헬맷{welding helmat}Welding Helmet for Electromagnetic Shielding {welding helmat}

본 발명은 전자파차폐용 용접헬맷에 관한 것으로서, 구체적으로는 작업자의 안면을 커버하는 용접헬맷에 있어서 용접에 의한 전자파가 차폐될 수 있도록 전자파차폐용 보호커버가 헬맷에 장착되어 있는 전자파차폐용 용접헬맷에 관한 것이다.
The present invention relates to a welding helmet for electromagnetic shielding, and in particular, in a welding helmet covering the operator's face, an electromagnetic shielding welding helmet equipped with a shield for electromagnetic shielding so as to shield electromagnetic waves by welding. It is about.

일반적으로 용접헬멧은 용접이나 절단 등의 작업을 수행할 경우 눈과 안면을 보호하기 위하여 사용된다. 그리고 이러한 용접헬멧에는 용접이나 절단 등의 작업을 수행할 경우 발생되는 강렬한 유해광으로부터 사용자의 눈을 보호하기 위한 눈In general, welding helmets are used to protect eyes and face when performing welding or cutting operations. In addition, these welding helmets are designed to protect the user's eyes from the intense harmful light generated when welding or cutting is performed.

부심방지장치(카트리지)가 고정 장착된다. 이와 같은 카트리지는 통상 780nm(IB)이상 365nm(UV)미만의 광선을 차단시키고 가시광선의 투과량을 제어하여 눈부심 없이 용접위치를 눈으로 확인할 수 있다.A primitive stopper (cartridge) is fixedly mounted. Such cartridges typically block light of less than 780nm (IB) and less than 365nm (UV) and control the amount of visible light to visually check the welding position without glare.

용접헬멧은 용접이나 절단 등의 작업을 수행할 경우 유해 전자파가 발생한다. 전자파란 전기 및 자기의 흐름에서 발생되는 광범위한 주파수 영역을 갖는 일전자기 에너지를 일컫는 것으로서 빛의 속도와 같이 초당 30만km로 진행한다. 전자파는 주파수에 따라 가정용 전원주파수(60Hz), 극저주파(0～1000Hz), 저주파(1～500kHz), 통신주파(100kHz～300MHz; AM, FM, TV 방송), 마이크로웨이브(300MHz～300GHz)로 분류되고, 적외선, 가시광선, 자외선, X선, 감마선 순으로 주파수가The welding helmet generates harmful electromagnetic waves when performing operations such as welding or cutting. Electromagnetic waves refer to the energy of a single electromagnetic field with a wide frequency range generated from the flow of electricity and magnetism. It travels at 300,000km per second like the speed of light. Electromagnetic waves are household power frequency (60Hz), ultra low frequency (0 ~ 1000Hz), low frequency (1 ~ 500kHz), communication frequency (100kHz ~ 300MHz; AM, FM, TV broadcasting), microwave (300MHz ~ 300GHz) depending on the frequency. Classified into infrared, visible, ultraviolet, x-ray, and gamma rays

높아지고 그만큼 파괴력이 증가한다.Increases and the destructive power increases.

한편, EMI(Electromagnetic Interference), 즉 전자파 장해는 전자파가 방사 또는 전도되어 다른 기기의 성능에 장해를 주는 것을 말하는 것으로서 전자파 방출에 대한 규제가 엄격해짐에 따라 전자제품 제조업계에서는 전자파 차폐에 대하여 보다 많은 연구를 하지 않을 수 없는 실정이다. 전자파 차폐처리를 수행하는 재료, 즉 소지재로는 아크릴로니트릴-부타디엔-스티렌(ABS), 폴리스티렌, 폴리카보네이트, 노릴, 자이롤, 아크릴, 아크릴변성 폴리염화비닐, 경질 염화비닐, FRP, 기타의 사출물 등이 사용되고 있다.On the other hand, electromagnetic interference (EMI), or electromagnetic interference, refers to electromagnetic radiation being radiated or conducted, which interferes with the performance of other devices. As the regulations on electromagnetic emission become more stringent, the electronics manufacturing industry is more concerned about electromagnetic shielding. Research is inevitable. Materials for the electromagnetic wave shielding treatment, i.e., the base material, include acrylonitrile-butadiene-styrene (ABS), polystyrene, polycarbonate, noryl, gyrol, acrylic, acrylic modified polyvinyl chloride, hard vinyl chloride, FRP, and other materials. Injection products and the like are used.

일반적으로 전자파 차폐기술은 재질의 하우징이나 시스템을 차폐하는 기술로서 소지면에 전자파 차폐용 도료를 코팅하는 것이다. 전자파 차폐기술을 적용하면 종래 사용되오던 고가의 금속 쉬트나 다른 부자재를 사용하지 않아도 되며 접지능력 및 차폐효과 자체를 직접 하우징이 갖게 된다.In general, electromagnetic shielding technology is to shield the housing or system of the material is to coat the electromagnetic shielding paint on the surface. Application of electromagnetic shielding technology eliminates the need for expensive metal sheets or other subsidiary materials that have been used in the past, and provides the housing with a grounding ability and a shielding effect itself.

전자파 차폐방법으로는 금속성분을 포함하는 도료를 사용하는 방법, 플라스틱 도금, 그리고 진공증착 등을 들 수 있다. 그러나, 진공증착의 경우는 가격이 고가이며 저항치에 대한 장기적인 신뢰성이 문제가 되고 있어 극히 제한적으로 사용되고 있다. 바람직한 방법은 도전성 촉매를 포함하는 코팅제로 소지면을 코팅하는 방법이며 종래 코팅제로는 니켈과 은의 얼로이를 포함하는 것을 들 수 있는 데, 이는 차폐효과가 낮아 그 응용에 있어서 한계가 있으며, 저항이 높고 전기적 특성이 불안하여 그 사용에 제한을 받아 왔다. 또한, 은으로만 이루어진 코팅제의 경우는 차폐효과가 향상될 수는 있으나 고가의 은만을 다량 첨가해야 하므로 가격상승을 초래하여 시장성이 떨어진다.
Examples of the electromagnetic shielding method include a method of using a paint containing a metal component, plastic plating, and vacuum deposition. However, in the case of vacuum deposition, the price is high and the long-term reliability of the resistance value becomes a problem and is used extremely limitedly. The preferred method is a method of coating a surface with a coating agent containing a conductive catalyst, and the conventional coating agent includes an alloy of nickel and silver, which has a low shielding effect and is limited in its application. Unstable traits have limited their use. In addition, in the case of a coating agent consisting only of silver, the shielding effect may be improved, but only a large amount of expensive silver should be added, resulting in an increase in price, resulting in poor marketability.

본 발명은 종래의 문제점을 개선하기 위한 것으로서, 용접헬맷의 전자파 치폐용으로서 여러가지 형태로 제작된 보호커버로 전자파를 커버할 수 있는 전자파차폐용 용접헬맷을 개발하는데 그 목적이 있다.An object of the present invention is to develop a welding shield for electromagnetic shielding which can cover electromagnetic waves with a protective cover made in various forms for shielding electromagnetic waves of a welding helmet.
