본 고안은 편광필터에 관한 것으로서, 더욱 상세하게는 음극선관의 제조공정중에 판넬 내면의 소점위치에 형광체를 도포하기 위하여 행하는 일련의 노광작업수행을 위한 노광대용 편광필터에 관한 것이다.The present invention relates to a polarizing filter, and more particularly, to a polarizing filter for an exposure stage for performing a series of exposure operations performed to apply a phosphor to a point on the inner surface of the panel during the manufacturing process of the cathode ray tube.

일반적으로 판넬 내면의 소정위치에 형광체를 도포하기 위해서 감광 제도포, 노광현상, 형광체도포 등을 행하는 소정의 과정을 거치는데 여기서, 규정된 조건으로 조정된 노광대에 새도우 마스크가 결합된 판넬을 올려놓고 광원에서 나오는 광량을 적절히 조정하여 노광을 행하는 것이다.In general, in order to apply a phosphor to a predetermined position on the inner surface of the panel, a predetermined process of performing photosensitive drawing, exposure phenomenon, and phosphor coating is performed. Here, a panel in which a shadow mask is combined is placed on an exposure table adjusted under prescribed conditions. The exposure is performed by appropriately adjusting the amount of light emitted from the light source.

종래에는 제1도에 도시된 바와 같이 노광대상면(9)의 중앙에 투광성의 면판(2)이 고정되어 있으며 내부에 광원(3), 제1렌즈(4), 제2렌즈(5) 및 제3렌즈(6)가 장착되어 있는 노광대(1)의 면판(2)위에 섀도우 마스크가 결합된 판넬(8)을 올려놓고 광원(3)으로 광을 조사하면서 판넬(8)의 곡률에 대응시켜 광원(3)의 기울기를 조정하여 노광을 하는데 이때 편면형 필터(7)를 이용하여 노광작업을 하였다.Conventionally, as shown in FIG. 1, the transmissive face plate 2 is fixed to the center of the exposure target surface 9, and the light source 3, the first lens 4, the second lens 5 and The panel 8 combined with the shadow mask is placed on the face plate 2 of the exposure table 1 on which the third lens 6 is mounted, and irradiates light with the light source 3 to correspond to the curvature of the panel 8. Exposure by adjusting the inclination of the light source 3 by using the single-sided filter 7 at this time.

그런데 종래와 같이 노광작업시 평면형 필터(7)를 이용하는 경우에는 판넬의 중심부에서 노광된 홀의 그 크기가 서로 다르고, 또한 R, G, B 각각에 대해서도 그 크기가 서로 다르기 때문에 튜브의 특성이 저하되는 문제점이 있었다.However, in the case of using the planar filter 7 during the exposure operation as in the prior art, the size of the hole exposed at the center of the panel is different from each other, and the sizes of the R, G, and B are different. There was a problem.

본 고안은 상기한 바와 같이 종래의 문제점을 해소하고자 안출된 것으로서, 본 고안은 편광 필터링(Filtering)을 통하여 광의 직선성 효과를 높임으로써 노광된 홀의 크기가 판넬의 중심부와 주변부 및 R, G, B 각각에 대해서 모두 동일하게 하여 튜브의 특성을 향상시킬 수 있는 편광 필터를 제공하는 것을 목적으로 한다.The present invention is conceived to solve the conventional problems as described above, the present invention is to increase the linearity effect of the light through polarization filtering (filtering) the size of the exposed hole in the center and periphery of the panel and R, G, B It aims at providing the polarizing filter which can improve the characteristic of a tube by making it the same about each.

상술한 목적을 달성하기 위해 본 고안에 의한 편광필터는 판넬의 곡률과 동일한 곡률을 갖도록 형성되어 있는 상면부의 상기 상면부로부터 수직하게 연장하는 측벽부를 구성되는 것을 특징으로 한다.In order to achieve the above object, the polarizing filter according to the present invention is characterized in that it comprises a side wall portion extending vertically from the upper surface portion formed to have the same curvature as the curvature of the panel.

이하 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

제3도는 도시되어 있는 바와 같이 본 고안에 따른 편광필터(11)가 장착된 노광대(1)의 내부에는 종래와 마찬가지로 내부에 광원(3), 제1렌즈(4), 제2렌즈(5) 및 제3렌즈(6)가 구비되어 있다. 그리고 노광대(1)에 설치된 필터 고정대(10)에는 본 고안에 따른 편광필터(11)를 고정시킨다. 상기 편광필터(11)는 제2도에 상세히 도시되어 있다. 상기 편광필터(11)는 대략 판넬(8)의 곡률과 유사한 형상으로 이루어져 있다. 즉 상기 편광필터(11)는 판넬(8)의 곡률과 유사한 곡률을 갖도록 형성되어 있는 상면부(12)와 상기 상면부(12)로부터 수직하게 연장하는 측벽부(13)로 구성되어 있다. 상기 측벽부(13)의 길이는 대략 판넬(8)의 크기 대 편광 필터(11)의 크기만큼 판넬(8)의 측벽부의 길이에 대응하는 길이로 형성하는 것이 바람직하다. 상기와 같이 형성된 편광필터(11)는 한 측벽부(13)의 하단부를 필터 고정대(10)에 고정시킨다.3 is a light source 3, a first lens 4, and a second lens 5 inside the exposure table 1 equipped with the polarization filter 11 according to the present invention, as shown. ) And a third lens 6. In addition, the polarizing filter 11 according to the present invention is fixed to the filter holder 10 installed on the exposure table 1. The polarization filter 11 is shown in detail in FIG. The polarizing filter 11 has a shape that is approximately similar to the curvature of the panel 8. That is, the polarization filter 11 is composed of an upper surface portion 12 formed to have a curvature similar to that of the panel 8 and a side wall portion 13 extending vertically from the upper surface portion 12. The length of the side wall portion 13 is preferably formed in a length corresponding to the length of the side wall portion of the panel 8 by approximately the size of the panel 8 to the size of the polarization filter 11. The polarization filter 11 formed as described above fixes the lower end of one side wall portion 13 to the filter holder 10.

도면 중 미설명부호 9는 노광대상면이다.In the figure, reference numeral 9 denotes an exposure target surface.

이와 같이 구성된 본 고안은 내부에 광원 (3), 제1, 제2 및 제3렌즈(4,5,6)가 장착되어 있는 노광대(1)의 면판(8)을 올려놓고 광원(3)으로 광을 조사하면서 판넬(8)의 곡률에 대응시켜 광원(3)의 기울기를 조정하여 노광을 할 때 상기 편광필터(11)를 이용하여 노광작업을 한다. 그러면 상기 광원(3)으로부터의 광이 상기 편광필터(11)의 필터링 효과에 의하여 선형적으로 필터링되어 판넬(8)의 내면에 조사된다.According to the present invention configured as described above, the light source 3 is mounted with the face plate 8 of the exposure table 1 on which the light source 3, the first, second and third lenses 4, 5, 6 are mounted. The exposure is performed using the polarization filter 11 when the exposure is performed by adjusting the inclination of the light source 3 in correspondence with the curvature of the panel 8 while irradiating light with the light. Then, the light from the light source 3 is linearly filtered by the filtering effect of the polarization filter 11 and irradiated to the inner surface of the panel 8.

이와 같이 편광 필터링을 통하여 광이 선형적으로 필터링되어 판넬 내면의 감광수지막에 조사되기 때문에 광의 직선성 효과가 증대됨으로써 노광된 홀의 크기가 판넬의 중심부와 주변부 및 R, G, B 각각에 대해서 모두 동일하게 노광을 할 수 있다.As the light is linearly filtered through the polarization filtering and irradiated to the photoresist film on the inner surface of the panel, the linearity effect of the light is increased, so that the size of the exposed hole is the center and the periphery of the panel and the R, G, and B, respectively. The exposure can be performed similarly.

상술한 바와 같이 본 고안에 의하면 노광작업시 노광된 홀이 판넬의 중심부와 주변부에서 그 크기가 서로 다르고, 또한 R, G, B 각각에 대해서도 그 크기가 서로 다르게 되는 문제점을 해소하여 튜브의 특성을 향상시킬 수 있는 효과가 있다.As described above, the present invention solves the problem that the holes exposed during exposure are different in size from the center and the periphery of the panel, and the sizes are different for R, G, and B, respectively. There is an effect that can be improved.
