본 고안은 칼라브라운관의 노광장치와 관련하여 새도우마스크의 슬릿(SLIT)을 통과한 광원으로부터의 빛이 노광대상 브라운관 형광면상의 소망되는 지점에 정확히 랜딩되는지의 여부를 검사할 때 새도우마스크가 광원으로부터의 열에 의해 도밍(DOMING)을 일으킴으로서 검사가 부정확하게 되는 것을 방지할 수 있도록 안출한 칼라브라운관의 노광검사장치에 관한 것이다.The present invention relates to an exposure apparatus of a color CRT, so that when a light from a light source passing through a SLIT of the shadow mask is accurately landed at a desired point on the CRT fluorescent surface to be exposed, the shadow mask is removed from the light source. The present invention relates to an exposure inspection apparatus for a color brown tube, which is designed to prevent the inspection from being inaccurate by causing doming by heat.

노광장치는 제1도에서 보는 바와 같이 면판(1)에 노광대상 브라운관판넬(4)을 올려 놓고 수은램프로 된 광원(3)을 작동시키면 이 광원(3)으로부터의 빛이 보정렌즈(2)들을 거쳐 적절히 보정된 후 새도우마스크(5)의 슬릿(5a)들을 통과하여 판넬(4)내면의 형광면에 조사됨으로써 이 형광면을 소정패턴으로 노광하도록 되어 있다.As shown in FIG. 1, when the exposure target CRT panel 4 is placed on the face plate 1 and the light source 3 made of mercury lamp is operated, the light from the light source 3 is corrected. After correcting properly through the slit 5a of the shadow mask 5, the fluorescent surface is irradiated to the fluorescent surface of the inner surface of the panel 4 to expose the fluorescent surface in a predetermined pattern.

이와 같은 노광장치를 사용하여 노광을 행함에 있어서는 실제의 노광작업에 들어가기저에 준비된 표준 판넬을 면판(1)상에 올려서 새도우마스크(5)의 슬릿(5a)들을 통과한 광원(3)으로부터의 빛이 상기 표준 판넬(4)상의 블랙스트라이프들사이의 구역에 정확히 랜딩되는지의 여부를 검사하고 그 검사결과에 따라 노광장치를 다시 정확시 세팅시킨 후 실제의 노광작업에 들어가게 되는데, 종래의 노광검사시에는 상술한 광원(3)으로부터의 빛의 랜딩검사시 새도우마스크(5)가 상기 광원(3)으로부터의 빛의 열에너지에 의해 도밍을 일으켜서 검사 및 그 검사결과에 의거한 노광장치의 교정작업이 종종 부정확하게 이루어짐으로써 대량의 불량을 유발하는 일이 빈번한 문제점이 있었다.In performing exposure using such an exposure apparatus, the standard panel prepared on the basis of the actual exposure operation is placed on the face plate 1 from the light source 3 passing through the slits 5a of the shadow mask 5. It is checked whether the light is landing in the area between the black stripes on the standard panel 4 correctly, and the exposure apparatus is correctly set again according to the inspection result, and the actual exposure operation is performed. In the case of the landing inspection of the light from the light source 3 described above, the shadow mask 5 is dommed by the thermal energy of the light from the light source 3 so that the inspection and the calibration operation of the exposure apparatus based on the inspection result are performed. Often inaccurate, causing a large amount of defects was a frequent problem.

본 고안은 이러한 종래의 문제점을 해소하기 위해 안출한 것으로서, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is devised to solve such a conventional problem, it will be described in detail based on the accompanying drawings as follows.

제2도는 본 고안에 따른 노광검사장치의 구성개요를 보여주는 그림인데, 이 장치는 판넬이 올려져 지지되는 면판(10)과 보정렌즈(20)들 및 광원(30)과 같은 통상적인 노광장치의 구성요소들을 포함하는 것이외에 상기 한편(10)상에 표준판넬(40)을 올려 놓고 광원(30)을 작동시켜서 새도우마스크(50)의 슬릿(50a)들을 통과한 상기 광원(30)으로부터의 빛이 판넬(40)내면상의 소정지점들에 올바로 랜딩되는지의 여부를 검사할 때 광원(30)의 빛에 의한 새도우마스크(50)의 도밍을 방지할 수 있도록 면판(10)내측에 설치제공되는 도밍방지판(60)을 포함하는 구성으로 되어 있다.2 is a view showing the configuration of the exposure inspection apparatus according to the present invention, which is a panel of the conventional exposure apparatus such as the face plate 10 and the correction lens 20 and the light source 30 is supported The light from the light source 30 passing through the slits 50a of the shadow mask 50 by operating the light source 30 with the standard panel 40 on the one side 10 in addition to including the components. Doming provided on the inside of the face plate 10 so as to prevent the shadowing of the shadow mask 50 by the light of the light source 30 when inspecting whether or not it lands properly at predetermined points on the inner surface of the panel 40. It is the structure containing the prevention plate 60.

상술한 랜딩검사는 표준 판넬(40)상의 모든 부위들에 대하여 실시해야 하는 것이 아니라 필요한 몇군데 부위들에 대해서만 실시하면 되므로 상기 도밍방지판(60)은 제3도의 예에서 보는 바와 같이 표준 판넬(40)상에 있어서 랜딩 검사사 필요한 부위들에 대해서만 광원(30)으로부터의 빛을 제한적으로 통과시켜 제공하는 통공(60a)들이 뚫리어 설치되어 있으며, 바람직하게는 열전도성이 낮고 내구성이 좋은 재질의 판체상에 이러한 통공(60a)들을 형성하여 구성토록 한다.The above-mentioned landing inspection is not required to be performed for all parts on the standard panel 40 but only for a few necessary parts. Therefore, the anti-domming plate 60 is used as a standard panel (as shown in the example of FIG. 3). 40) is provided with through holes (60a) to provide a limited passing of light from the light source 30 to only the parts required by the landing inspector, preferably of low thermal conductivity and durable material The through holes 60a are formed on the plate to be configured.

상기와 같은 도밍방지판(60)의 설치사용은 광원(30)으로부터의 빛중에서 검사목적상 꼭 필요한 최소한의 빛만 새도우마스크(50)쪽으로 제한 통과시킬 수 있으므로 상기 광원(30)의 빛에 의한 새도우마스크(50)의 도밍현상을 극소화시켜 정확한 랜딩검사가 이루어지도록 하여 주고 이로써 노광과 관련한 불량발생을 크게 줄일 수 있는 현저한 효과를 제공한다.Since the installation and use of the anti-doping plate 60 as described above can limit only the minimum light necessary for inspection purposes among the light from the light source 30 toward the shadow mask 50, the shadow by the light of the light source 30 can be limited. By minimizing the doming phenomenon of the mask 50 to ensure accurate landing inspection, thereby providing a remarkable effect that can greatly reduce the occurrence of defects associated with exposure.
