본 고안은 칼라음극선관의 스크린 제조시 노광과정에서 조도보정용 편광필터의 오염으로 인한 스크린의 흑점불량을 방지하기 위한 칼라 음극선관 제조용 노광장치에 관한 것이다.The present invention relates to an exposure apparatus for manufacturing a color cathode ray tube for preventing a black spot defect of the screen due to contamination of the luminance correction polarization filter during the exposure process during the manufacturing of the color cathode ray tube.
칼라음극선관의 스크린에는 R,G,B형광체가 소정의 패턴을 형성하여 부착되는 바, 이들 형광체가 패턴을 이루게 하기 위하여 스크린 상에 감광성수지를 도포하고 노광하여 현상처리한 다음, 노광부에 소정 색상의 형광체를 도포하는 공정을 3회 반복하여 소망의 형광체패턴이 형성되게 하고 있다.On the screen of the color cathode ray tube, R, G, and B phosphors are attached to form a predetermined pattern. In order to form the phosphors, photosensitive resins are applied on the screen, exposed to light, and developed. The process of applying the phosphor of color is repeated three times so that a desired phosphor pattern is formed.
상술한 공정에 있어서, 노광은 제3도에 도시한 바와 같은 셔터(S)가 설치된 수은램프(L)을 노광원으로 하고, 이 수은램프(L)의 상측에 보정렌즈(LS)와 조도보정필터(F)를 순차 배열된 노광장치를 사용하여, 칼라음극선관의 페이스(FA)에 패턴마스크(M)을 개재시켜서 노광을 행하고 있다.In the above-described process, exposure is performed by using a mercury lamp L provided with a shutter S as shown in FIG. 3 as an exposure source, and correcting the correction lens LS and illuminance on the mercury lamp L side. Exposure is performed using the exposure apparatus in which the filter F was arrange | positioned sequentially through the pattern mask M on the face FA of a color cathode ray tube.
상술한 노광장치에서, 보정렌즈(LS)의 상방에 위치하는 조도보정 필터(F)는 패턴마스크(M)을 통과하여 투사되는 빛이 스크린의 중앙과 주변에서 균일한 크기의 돗트나 스트라 이프로 나타나게 하는 역활을 한다.In the above-described exposure apparatus, the illumination correction filter F located above the correction lens LS has a dot or stripe of uniform size at the center and the periphery of the screen where the light projected through the pattern mask M is projected. It serves to make it appear.
그러나, 이 조도보정필터(F)는 노광장치에서 홀더에 의해 고정설치되는 것이므로, 만약에 조도보정필터(F)의 표면에 먼지나 이물질이 유착하게 되면 광의 투과율이 부분적으로 저하되기 때문에 노광패턴이 균일치 않게되는 결점을 나타내고 있다.However, since the illuminance correction filter F is fixedly installed by the holder in the exposure apparatus, if dust or foreign matter adheres to the surface of the illuminance correction filter F, the light transmittance is partially lowered. The defect which becomes uneven is shown.
즉, 조도보정필터(F)에 이물이 존재할 경우, 페이스(FA)의 스트린에서 이 부분에 대응하는 노광부위는 비노광 혹은 불완전한 노광으로 되어, 세척시 씻겨나가 버리므로 스크린에 패턴형성이 되지않는 흑점불량이 발생하고, 그 밖에도 조도분포가 좋지 않게 되는 결점이 있다.That is, if foreign matter is present in the illuminance correction filter F, the exposed part corresponding to this part in the screen of the face FA becomes non-exposed or incomplete exposure, and is washed away during cleaning, thereby preventing pattern formation on the screen. There are other disadvantages such as unsatisfactory sunspot defects and poor illuminance distribution.
이와같은 조도보청필터(F)에 의해 발생하는 결점은 노광시에 이를 회전시킴으로써 해결될 수 있다.The defect caused by such a roughness hearing filter F can be solved by rotating it at the time of exposure.
따라서, 본 고안의 목적은 조도보정필터를 회전시킬 수 있게 구성하여, 스크린 제조후의 흑점불량을 방지할수 있는 칼라음극선관 제조용 노광장치를 제공함에 있다.Accordingly, an object of the present invention is to provide an exposure apparatus for manufacturing a color cathode ray tube that can be configured to rotate the roughness correction filter to prevent black spot defects after screen manufacturing.
상기 목적에 따라, 본 고안의 노광장치는 내주에 조도보정필터가 끼워지고 외주에 워엄휠을 형성하고 있는 링체와, 전기한 워엄휠에 치차연결되는 워엄기어를 출력단에 보유하는 구동모우터가 렌즈 장착대상에 배치되어 있음을 특징으로 한다.According to the above object, the exposure apparatus of the present invention has a ring body having an illuminance correction filter fitted into an inner circumference and forming a worm wheel on an outer circumference, and a drive motor having a worm gear connected to the electric worm wheel at an output stage at the output end thereof. It is characterized in that it is disposed on the mounting object.
이하, 본 고안의 바람직한 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안 노광장치의 구조를 나타내는 측단 면도로서, 셔터(1)이 배치된 수은램프(2)의 상측에는 보정렌즈(3)을 고정하기 위한 렌즈 장착대(4)가 위치하고 있다.FIG. 1 is a side end view showing the structure of the exposure apparatus of the present invention, and a lens mount 4 for fixing the correcting lens 3 is located above the mercury lamp 2 in which the shutter 1 is disposed.
상기한 렌즈 장착대(4)는 페이스(5)를 재치하기 위한 스크린 장착대(6)가 함께 지지대(7)에 의해 설치되어있다.The lens mount 4 is provided with a screen 7 with a screen 7 for mounting the face 5 thereon.
렌즈 장착대(4)의 상측 내주면에는 베어링(8)이 끼워져 있고, 이 베어링(8)은 후술하는 링체(9)를 회전 가능하게 지지하고 있다.A bearing 8 is fitted to the upper inner peripheral surface of the lens mount 4, and the bearing 8 rotatably supports the ring body 9 described later.
링체(9)는 내부에 조도보정필터(10)을 고정부착하고 있는 것으로서 제2도에 도시한 바와 같이, 그 외주에 형성된 치차에 의해 워엄휠(11)을 이루고 있다.The ring body 9 is fixed to the illuminance correction filter 10 therein, and as shown in FIG. 2, the worm wheel 11 is formed by a gear formed on its outer periphery.
상기한 워엄휠(11)에는 워엄기어(12)가 맞물려 있으며, 이 워엄기어(12)는 모우터(13)의 출력축(14)에 일체로 형성된 것이다.The worm gear 12 is engaged with the worm wheel 11, and the worm gear 12 is formed integrally with the output shaft 14 of the motor 13.
이상과 같은 구성에 의해, 본 고안의 노광장치에서는 조도보정 필터(10)이 회전할 수 있게 된다.With the above configuration, the illuminance correction filter 10 can rotate in the exposure apparatus of the present invention.
즉, 모우터(13)의 구동에 의해 출력축(14)가 회전을 시작하면, 그 선단측 워엄기어(12)에 맞물린 워엄휠(1)이 회전하게 되고, 이 워엄휠(11)의 회전은 그 내부에 고정된 조도보정필터(10)의 회전을 초래하게 되며, 그결과로 전기한 조도보정필터(10)의 광 투과면에 이물이 흡착되어 있는 경우, 전기한 이물흡착면이 링체(9)의 회전에 수반하여 회전 이동되기 때문에 종래와 같이 스크린 상의 어느 한 부분이 비노광되거나 혹은 불완전하게 노광되는 일이 없게 되는 것이다.That is, when the output shaft 14 starts to rotate by the drive of the motor 13, the worm wheel 1 meshed with the front worm gear 12 rotates, and the rotation of this worm wheel 11 When the foreign matter is adsorbed on the light transmitting surface of the roughness correction filter 10, as a result, rotation of the roughness correction filter 10 fixed therein is carried out. Because of the rotational movement with the rotation of), any portion on the screen is not exposed or incompletely exposed as in the prior art.
그러므로 본 고안 노광장치에 의하면, 균일한 노광을 통한 스크린패턴을 얻을 수 있어서 화질의 향상을 도모할 수 있는 실용성을 갖는 것이다.Therefore, according to the exposure apparatus of the present invention, it is possible to obtain a screen pattern through uniform exposure, thereby having practicality that can improve image quality.
상술한 실시예에서 조도보정필터를 회전시키기 위한 수단으로서, 워엄과 워엄휠을 예시하고 있으나, 본 고안은 이에 한정되는 것은 아니며, 본 고안의 기술적 사상을 일탈하지 않는 범위 내에서 변경 실시가 가능하며,예컨대 워엄과 워엄휠 대신에 풀리를 사용한 벨트전동방식이나 혹은 스프로켓을 사용한 체인구동방식으로 변경시킬 수도 있다.As a means for rotating the illuminance correction filter in the above-described embodiment, the worm and the worm wheel are exemplified, but the present invention is not limited thereto, and modifications may be made without departing from the technical spirit of the present invention. For example, it could be changed to belt drive using pulley instead of worm and worm wheel, or chain drive using sprocket.
