본 고안은 노광대에 관한 것으로서, 더욱 상세하게는 음극선관에 제조공정중에 판넬 내면에 형광막을 형성하기 위하여 소정의 노광작업을 행하기 위한 노광대에 관한 것이다.The present invention relates to an exposure stage, and more particularly, to an exposure stage for performing a predetermined exposure operation to form a fluorescent film on the inner surface of the panel during the manufacturing process in the cathode ray tube.
일반적으로 판넬 내면에 형광체를 도포하기 위하여 감광막도표, 노광 현상 및 형광체막형성 등의 과정을 거치는데 규정된 조건으로 조정된 노광대에 섀도우 마스크가 결합된 판넬을 올려놓고 광원에서 나오는 광량을 적절히 조절하여 노광을 하게 된다.In general, in order to apply the phosphor on the inner surface of the panel, the photoresist diagram, exposure development, and phosphor film formation are performed. Exposure is performed.
종래에는 제1도에 도시된 바와 같이 노광대상면(9)의 중앙에 투광성의 면판(2)이 고정되어 있으며 내부에 광원(3), 제1렌즈(4), 제2렌즈(5), 제3렌즈(6) 및 배광필터(7)가 장차되어 있는 노광대(1)의 면판(2)위에 섀도우 마스크가 결합된 판넬(8)을 올려놓고 광원(3)을 이용하여 노광을 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, The panel 8 combined with the shadow mask was placed on the face plate 2 of the exposure table 1 in which the third lens 6 and the light distribution filter 7 were mounted, and the exposure was performed using the light source 3.
그런데 브라운관완성 후 ITC 작업시 YBC(Yoke Pull Back)의 수치가 작거나 큰 경우 ITC 작업의 능률의 떨어지며 튜브 자체의 품위가 저하되므로 YPB를 보정하여야 하는데 종래의 조광대(1)에 의한 노광작업으로는 YPB를 보정할 수 없는 문제점이 있었다,.However, if the value of YBC (Yoke Pull Back) is small or large during the ITC work after completion of the CRT, the efficiency of ITC work is reduced and the quality of the tube itself is deteriorated. Therefore, the YPB should be corrected. There was a problem that could not correct YPB.
본 고안은 상기한 바와 같은 종래의 문제점을 해소하고자 안출된 것으로서, 본 고안은 ITC 작업시 YPB 수치가 작거나 큰 경우 노광수정작업에 의해 YPB 수치를 보정할 수 있어 ITC 작업의 능률과 브라운관의 품위를 향상시킬 수 있는 노광대를 제공하는 것을 목적으로 한다.The present invention was devised to solve the conventional problems as described above, the present invention can correct the YPB value by the exposure correction operation when the YPB value is small or large during the ITC operation, the efficiency of the ITC operation and the quality of the CRT It is an object of the present invention to provide an exposure table capable of improving.
상술한 목적을 달성하기 위해 본 고안에 의한 노광대는 내측 벽부에 구비된 다수개의 브라켓에 장착되며 실린더봉을 구비한 다수개의 실린더와, 다수개의 상기 실린더봉의 상부에 고정지지되며 노광대상면에 형성된 원형구멍을 통하여 상하로 슬라이딩 가능하게 유지되는 면판과, 상기 다수개의 실린더에 전기적 신호를 주어 다수개의 실린더봉을 상하로 이동시키기 위한 조작수단으로 구성되는 것을 특징으로 한다.In order to achieve the above object, the exposure table according to the present invention is mounted on a plurality of brackets provided on the inner wall, and includes a plurality of cylinders having a cylinder rod, and a plurality of cylinders fixed on an upper portion of the plurality of cylinder rods and formed on an exposure target surface. It is characterized in that it comprises a face plate which is maintained to be slidable up and down through the hole, and the operation means for moving the plurality of cylinder rods up and down by giving an electrical signal to the plurality of cylinders.
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.
제2도에 도시되어 있는 바와 같이 본 고안에 따른 노광대(20)의 내부에는 종래와 마찬가지로 내부에 광원(3), 제1렌즈(4), 제2렌즈(5), 제3렌즈(6) 및 배광필터(7)가 장착되어 있다. 그리고 노광대(20)의 내측 벽부에는 2개의 브라켓(13)이 구비되어 있다. 상기 브라켓(13)에는 각각 실린더(14)가 장착되며 실린더봉(15)의 상부는 면판(12)에 고정된다. 면판(12)은 실린더봉(15)의 상부에 고정지지되며 노광대(20)의 노광대상면(10)에 형성된 원형구멍(11)의 상하로 슬라이딩 가능하게 유지되어 있다. 노광대(20)의 외측 벽부의 상부 부근에는 2개의 실린더(14)에 전기적 신호를 주어 실린더봉(15)을 동시에 상하로 이동시키기 위한 조작수단(16)이 구비되어 있다.As shown in FIG. 2, the light source 3, the first lens 4, the second lens 5, and the third lens 6 are inside the exposure table 20 according to the present invention as in the prior art. ) And light distribution filter 7 are mounted. In addition, two brackets 13 are provided on the inner wall of the exposure table 20. Cylinders 14 are mounted on the brackets 13, respectively, and an upper portion of the cylinder rod 15 is fixed to the face plate 12. The face plate 12 is fixedly supported on the upper part of the cylinder rod 15 and is slidably held up and down of the circular hole 11 formed in the exposure target surface 10 of the exposure table 20. In the vicinity of the upper portion of the outer wall of the exposure table 20, operation means 16 for providing an electrical signal to the two cylinders 14 to move the cylinder rod 15 up and down simultaneously is provided.
이와 같이 구성된 본 고안은 ITC 작업시 YPB 수치가 작거나 큰 경우 노광수정작업에 의해 상기 YPB 수치를 보정하고자 할 경우 노광대(20)의 면판(12)위에 안치된 판넬(8)에 노광작업을 할 때 조작수단(16)을 조작하게 되면 실린더(14)의 실린더봉(15)이 상하로 동시에 이동된다. 이에 따라 실린더봉(14)의 상부에 고정지지되어 있는 면판(12)이 상하로 이동되어 광원(3)으로부터 판넬(8)까지의 거리를 조절할 수 있게 된다. 이때 상기 2개의 실린더봉(15)이 동시에 이동되기 때문에 면판(12)은 수평을 유지하면서 이동된다. 상기와 같이 광원(3)과 판넬(8) 사이의 거리를 조절하여 노광 작업함으로써 YPB 수치를 보정할 수 있다.According to the present invention configured as described above, when the YPB value is small or large during the ITC operation, when the YPB value is to be corrected by the exposure correction operation, the exposure operation is performed on the panel 8 placed on the face plate 12 of the exposure table 20. When the operation means 16 is operated when the cylinder rod 15 of the cylinder 14 is simultaneously moved up and down. Accordingly, the face plate 12 fixed to the upper portion of the cylinder rod 14 is moved up and down to adjust the distance from the light source 3 to the panel 8. At this time, since the two cylinder rods 15 are moved at the same time, the face plate 12 is moved while maintaining the horizontal. As described above, the YPB value can be corrected by adjusting the distance between the light source 3 and the panel 8 to perform the exposure operation.
상술한 바와 같이 본 고안에 의하면 ITC 작업시 YPB 수치가 작거나 큰 경우 노광수정작업에 의해 YPB 수치를 보정할 수 있어 ITC 작업의 능률과 브라운관의 품위를 향상시킬 수 있는 효과가 있다.As described above, according to the present invention, when the YPB value is small or large during the ITC operation, the YPB value can be corrected by the exposure correction operation, thereby improving the efficiency of the ITC operation and the quality of the CRT.
