본 고안은 음극선관의 알루미늄 증착용 히이터에 관한 것으로서 더 상세하게는 패널 내면에 균일한 알루미늄 증착막을 형성할 수 있도록 그 구조를 개량한 것에 관한 것이다.The present invention relates to a heater for aluminum deposition of a cathode ray tube, and more particularly, to an improved structure to form a uniform aluminum deposition film on the inner surface of the panel.
일반적으로 음극선관의 패널(P) 내면에는 형광막(S)이 소정의 패턴으로 형성되고 그 위에 형광막의 발광휘도증가, 형광면의 전위강화 및 이온충격에 의한 형광면의 탄화방지를 위한 알루미늄막(A)이 진공증착에 의해 형성된다(제1도 참조). 이러한 알루미늄막의 진공증착방법은 음극선관 내부를 세정, 락카막, 흑연 도포 등의 전처리 공정을 실시한 다음 제1도에 표현한 바와 같은 코일형 히이터(H')에 알루미늄 재료(W)를 얹고 이를 네크튜브(neck tube)에 삽입한 후 내부공기를 빼내어 진공화시키고 나서 히이터(H')를 가열하여 고순도의 알루미늄(99.99%)을 증발시키는 방법에 의해 음극선관 내부에 얇은 알루미늄막(A)이 형성된다.In general, the fluorescent film S is formed in a predetermined pattern on the inner surface of the panel P of the cathode ray tube, and the aluminum film A is used for preventing the carbonization of the fluorescent surface by increasing the luminance of the fluorescent film, enhancing the potential of the fluorescent surface, and ion bombardment thereon. ) Is formed by vacuum deposition (see FIG. 1). In this vacuum deposition method of the aluminum film, the inside of the cathode ray tube is subjected to a pretreatment process such as washing, lacquer film and graphite coating, and then the aluminum material (W) is placed on the coil heater (H ') as shown in FIG. A thin aluminum film (A) is formed inside the cathode ray tube by inserting it into the neck tube, evacuating the internal air, evacuating it, and heating the heater H 'to evaporate high purity aluminum (99.99%). .
그러나 상기의 방법을 통하여 실시되는 종래 음극선관의 알루미늄 증착용 히이터는 제2도에 도시된 바와 같이 텅스텐 코일히이터(H')를 형성함에 있어서, 일측전극(1')이 수직으로 뻗어 오르다가 상부에서 권회되어 일정한 피치와 지름으로 코일형 몸체(2')를 형성하되 하부에서 중앙을 횡단하여 알루미늄재료(W)가 얹혀지는 받침대(3')를 만들어 주고 아래로 뻗어 타측전극(4')을 형성하게끔 구성되어 있다.However, the aluminum deposition heater of the conventional cathode ray tube carried out through the above method, as shown in FIG. 2, in forming the tungsten coil heater H ', one electrode 1' is vertically extended and then It is wound at to form a coil-shaped body (2 ') with a constant pitch and diameter, but make a pedestal (3') on which the aluminum material (W) is placed across the center from the bottom and extends down the other electrode (4 ') It is configured to form.
그러나 이와 같이 구성된 종래 음극선관의 알루미늄 증착용 히이터는 코일형 몸체(2')가 동일직경으로 형성되어 히이터(H)의 열에 의해 증발되는 알루미늄재료(W)가 상기 코일형 몸체(2')에 의해 패널(P) 내면의 가장자리로부로 원활하게 증발되지 못하고 중앙부로 집중적으로 증발됨에 따라 패널 내면의 가장자리부보다 중앙부에 집중적으로 알루미늄이 증착되게 되어(본원인의 실험에 의하면 중앙부가 가장자리 보다 약 15∼20% 정도 증착이 많이 됨) 소망하는 형광면의 발광휘도 및 형광면의 전위를 얻을 수 없는 문제점이 있었다.However, in the heater for aluminum deposition of the conventional cathode ray tube configured as described above, the coil type body 2 'is formed with the same diameter so that the aluminum material W is evaporated by the heat of the heater H to the coil type body 2'. As a result of the concentrated evaporation to the center part rather than the evaporation to the edge of the inner surface of the panel P smoothly, aluminum is deposited more centrally than the edge of the inner surface of the panel P. Deposition of about 20% is abundant) There is a problem in that the emission luminance of the desired fluorescent surface and the potential of the fluorescent surface cannot be obtained.
본 고안은 상술한 바와 같은 문제점을 감안하여 안출된 것으로서, 패널내면에 알루미늄막을 균일하게 형성시킬 수 있는 음극선관의 알루미늄 증착용 히이터를 제공함에 그 목적이 있다.The present invention has been made in view of the above problems, and an object thereof is to provide a heater for aluminum deposition of a cathode ray tube capable of uniformly forming an aluminum film on an inner surface of a panel.
상기의 목적을 달성하기 위하여 본 고안은, 상부로 부터 하부로 갈수록 점차적으로 그 직경이 크도록 권회된 코일형 몸체를 구비하여 된 점에 그 특징이 있다.In order to achieve the above object, the present invention is characterized in that it is provided with a coiled body wound so that its diameter gradually increases from the top to the bottom.
이하 본 고안에 따른 음극선관의 알루미늄 증착용 히이터의 바람직한 일 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, a preferred embodiment of a heater for aluminum deposition of a cathode ray tube according to the present invention will be described in detail with reference to the accompanying drawings.
제3도에는 본 고안에 따른 음극선관의 알루미늄 증착용 히이터가 도시되어 있는바, 이는 일측전극(1)이 수직상방으로 뻗어 오르다가 상부에서 권회되어 코일형 몸체(2)를 형성하되 그 하부에서 중앙을 횡단하여 알루미늄 재료(W)가 얹혀지는 받침대(3)를 형성하고 아래로 뻗어 타측전극(4)을 형성하게끔 구성된다. 그리고 본 고안의 특징에 따라 상기 코일형 몸체(2)는 상부에서 하부로 갈수록 그 직경이 점차적으로 크게 형성되어 있다.3 is a heater for aluminum deposition of a cathode ray tube according to the present invention, which is one electrode (1) extends vertically upward and is wound from the top to form a coil-shaped body (2) at the bottom It is configured to form a pedestal 3 on which the aluminum material W is placed across the center and to extend downward to form the other electrode 4. And according to the characteristics of the present invention, the coil-like body 2 is formed to gradually increase in diameter from the top to the bottom.
이와 같이 구성된 본 고안의 따른 음극선관의 알루미늄 증착용 히이터는 코일형 몸체(2)가 상부에서 하부로 갈수록 그 직경이 점차적으로 크게 권회되어 있으므로 히이터(H)의 열에 의해 증착되는 알루미늄재료(W)가 권회된 코일형 몸체(2)의 직경차로 인해 생긴 틈을 통하여 패널(P) 내면의 가장자리부로의 증발이 원활하게 됨에 따라 패널 내면의 중앙부와 가장자리부에 균일하게 알루미늄이 증착되게 된다.The aluminum deposition heater of the cathode ray tube according to the present invention configured as described above is the aluminum material (W) is deposited by the heat of the heater (H) because the diameter of the coil body (2) is gradually wound larger from the top to the bottom As the evaporation to the edge of the inner surface of the panel P is smooth through the gap created by the diameter difference of the coiled body 2 wound around, the aluminum is uniformly deposited at the center and the edge of the inner surface of the panel.
이와 같이 본 고안에 따른 음극선관의 알루미늄 증착용 히이터는 패널 내면에 균일하게 알루미늄막을 형성할수 있으므로 음극선관의 형광면 발광휘도의 향상 및 형광면의 전위를 향상시킬수 있어 선명한 화상을 가진 음극선관을 제작할 수 있게 된다.As described above, the aluminum deposition heater of the cathode ray tube according to the present invention can form an aluminum film uniformly on the inner surface of the panel, thereby improving the fluorescent surface luminous luminance of the cathode ray tube and improving the potential of the fluorescent surface, so that a cathode ray tube having a clear image can be manufactured. do.
