본 고안은 음극선관(陰極線管)에 관한 것으로, 더 상세히는 음극선관의 폭축(implosion)을 방지하는 방폭밴드(防爆 band)에 관한 것이다.The present invention relates to a cathode ray tube, and more particularly to an explosion-proof band for preventing the expansion of the cathode ray tube.
음극선관은 전자총에서 전자를 발생시켜 이를 집속 및 가속시켜 형성한 전자빔(electron beame)으로 형광면을 선택적으로 발광시킴으로써 화상을 표시하는 장치이다. 이에따라 전자빔의 안정적 발생과 가속을 위해서는 전자빔의 이동 경로상에 기체분자등이 존재하면 안되므로 음극선관의 내부는 고진공상태로 배기(排氣)되지 않으면 안된다.A cathode ray tube is an apparatus that displays an image by selectively emitting a fluorescent surface with an electron beam formed by generating electrons from an electron gun, focusing and accelerating them. Accordingly, in order to stably generate and accelerate the electron beam, gas molecules and the like must not exist on the path of the electron beam, so the inside of the cathode ray tube must be exhausted in a high vacuum state.
이와같이 음극선관을 배기시켜 밀봉하면, 제1도에 도시한 바와같이 대기압에 의해 음극선관(T)의 패널(panel:P)과 펀넬(funnel:F)은 내측으로 수축하고자 하고 패널(P)의 스커어트(skirt:S)로 외측으로 팽창하고자 하는 큰 응력상태가 발생된다.When the cathode ray tube is evacuated and sealed in this manner, as shown in FIG. 1, the panel (P) and the funnel (F) of the cathode ray tube T are caused to shrink inward by atmospheric pressure, and the panel P A large stress condition is created to expand outward with a skirt (S).
이러한 응력은 통상적인 상태에서는 음극선관(T)의 자체 강도에 의해 지탱될 수 있으나, 음극선관(T)은 취성(脆性) 재질인 유리로 제작되므로 외부 충격 등에 의해 급격히 촉축될 위험성이 상존한다.Such a stress may be supported by the strength of the cathode ray tube T in a normal state, but since the cathode ray tube T is made of glass, which is brittle, there is a risk of being rapidly accelerated due to an external impact.
이에따라 패널(P)의 스커어트(S)외주에 방폭밴드를 큰 인장력으로 감아주어 팽창응력을 감소시키는 보강방법이 사용되고 있다. 이러한 방폭밴드는 밴딩(banding) 방식에 따라 열수축(shrinkage) 밴딩방식과 인장(tension) 밴딩방식으로 나뉘는데, 특히 열수축 밴딩방식이 생산 자동화에 적절한 공정특성을 가져 관심이 집중되고 있다.Accordingly, a reinforcing method is used to reduce the expansion stress by winding the explosion-proof band with a large tensile force on the outer periphery of the skirt P of the panel P. The explosion-proof band is divided into a heat shrink banding method and a tension banding method according to a banding method, and in particular, the heat shrink banding method has an attention process because it has an appropriate process characteristic for production automation.
이러한 열수축 밴딩 방식은 제2도에 도시한 바와같이 음극선관(T)의 유리재질 보다 열팽창율이 큰 금속제 밴드(B)를 고온으로 가열한 뒤, 패널(P)에 씌워 냉각시킴으로써 열팽창율의 차이에 의해 인장력을 부여하게 된다. 그런데 고온의 금속제 밴드(B)를 유리제 패널(P)에 직접 씌우면 패널(P)에 열충격등으로 크랙(crack)이 발생되기 쉬우며, 냉각에 따른 인장력의 증가에 의해 패널(P)로부터 이탈되기 쉽다. 이에따라 절연과 이탈방지 목적으로 패널(P)의 스커어트(S) 외주에 접착테이프(A)를 부착한 뒤, 그 위에 방폭밴드(B)를 감아주는 방법이 일반적으로 사용되고 있다.In this heat shrink banding method, as shown in FIG. 2, the thermal expansion coefficient is different by heating the metal band B having a higher thermal expansion rate than the glass material of the cathode ray tube T to a high temperature and then covering the panel P with cooling. The tensile force is given by. However, when the high-temperature metal band B is directly covered on the glass panel P, cracks are likely to occur due to thermal shocks on the panel P, and are separated from the panel P by an increase in tensile force due to cooling. easy. Accordingly, a method of attaching the adhesive tape A to the outer periphery of the skirt S for the purpose of insulation and separation, and then winding the explosion-proof band B thereon is generally used.
그러나 이러한 종래의 방법은 접착 테이프(A)를 별도의 공정을 통해 패널(P)에 부착하는 것이므로 밴딩작업이 번잡하여 생산성이 저하될 뿐만 아니라 그에 따른 공수증가와 설비가 요구되어 음극선관(T)의 제조원가도 상승하는 문제가 있었다.However, since the conventional method is to attach the adhesive tape (A) to the panel (P) through a separate process, the bending work is complicated, not only decreases the productivity, but also increases the air supply and equipment according to the cathode ray tube (T). There was also a problem of rising manufacturing costs.
본 고안의 목적은 상술한 종래의 문제점을 감안하여 접착테이프를 별도의 공정을 통하지 않고서도 패널에 부착시킬 수 있는 음극선관의 방폭밴드를 제공하는 것이다.It is an object of the present invention to provide an explosion-proof band of a cathode ray tube capable of attaching an adhesive tape to a panel without a separate process in view of the above-described conventional problems.
이와같은 목적을 달성하기 위해 본 고안에 의한 음극선관의 방폭밴드는 그 내주에 패널의 스커어트 외주에 부착되는 접착테이프가 구비되는 것을 특징으로 한다.In order to achieve the above object, the explosion-proof band of the cathode ray tube according to the present invention is characterized in that the adhesive tape is attached to the outer periphery of the skirt of the panel.
본 고안의 바람직한 특징에 의하면, 접착테이프가 양면 테이프로 구성된다.According to a preferred feature of the present invention, the adhesive tape is composed of a double-sided tape.
이에따라 본 고안은, 방폭밴드를 패널 외주에 밴딩하는 한 번의 작업으로 이들간에 접착테이프를 개재시킬수 있게되므로 음극선관의 공수와 원가절감 및 생산성 향상에 큰 효과를 발휘한다.Accordingly, the present invention, because it is possible to interpose the adhesive tape between them in one operation of bending the explosion-proof band to the outer periphery of the panel, it has a great effect on the airborne and cost reduction and productivity of the cathode ray tube.
이하 첨부된 도면을 참조하여 본 고안의 한 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제3도에서, 음극선관(T)의 패널(P) 외주에 밴딩되는 금속제 방폭밴드(B)의 내주에는 본 고안의 특징에 따라 밴딩시 온도차에 의한 패널(P)의 열충격 방지와 밴드(B)의 이탈을 방지하는 접착테이프(A)가 구비된다. 이에따라 접착테이프(A)는 패널(P)의 스커어트(S) 외주에 안정되게 부착되는 것이 바람직한 바, 본 고안 접착테이프(A)는 바람직하기로 양면 테이프로 구성되어 방폭밴드(B)의 내부에 부착됨으로써 구비된다.In Figure 3, the inner circumference of the metal explosion-proof band (B) that is banded to the outer circumference of the panel (P) of the cathode ray tube (T) in accordance with the features of the present invention prevents thermal shock and band (B) of the panel (P) due to the temperature difference when An adhesive tape (A) for preventing the separation of the) is provided. Accordingly, the adhesive tape (A) is preferably attached stably to the outer periphery of the skirt (S) of the panel (P), the adhesive tape (A) of the present invention is preferably composed of a double-sided tape to the inside of the explosion-proof band (B) It is provided by being attached to.
이와같이 구성된 본 고안 방폭밴드(B)는 열수축 밴딩방식으로 패널(P)의 스커어트(S) 외주에 밴딩되는데, 그 내주에 접착테이프(A)가 구비되어 있으므로 방폭밴드(B)를 가열하여 패널(P) 외주에 씌운 뒤 냉각시키는 작업만으로도 패널(P)과의 사이에 접착테이프(A)를 개재시켜 밴딩할 수 있게된다. 이에따라 종래와 같이 별도의 테이프 부착공정 없이도 접착테이프(A)를 패널(P)의 스커어트(S) 외주에 부착시킬 수 있다.The explosion-proof band (B) of the present invention configured as described above is banded on the outer periphery of the skirt (S) of the panel (P) by a heat shrink banding method. (P) It is possible to band by interposing the adhesive tape A between the panel P only by cooling the cover after covering the outer periphery. Accordingly, the adhesive tape A may be attached to the outer periphery of the skirt P of the panel P without a separate tape attaching process as in the related art.
이와같이 본 고안에 의하면, 별도의 테이핑(taping)공정 없이도 패널과 방폭밴드간에 접착테이프를 간단하게 개재시킬 수 있으며, 이에따라 본 고안은 음극선관의 공수와 원가 절감은 물론 생산성을 향상시키게 된다.As such, according to the present invention, an adhesive tape can be easily interposed between the panel and the explosion-proof band without a separate taping process. Accordingly, the present invention improves productivity and cost as well as the cost and cost of the cathode ray tube.
