본 고안은 음극선관용 노광장치에 관한 것으로서, 보다 상세하게는 노광시 광원의 조사점을 조절할 수 있도록 구조되는 음극선관용 노광장치에 관한 것이다.The present invention relates to an exposure apparatus for a cathode ray tube, and more particularly, to an exposure apparatus for a cathode ray tube, which is structured so as to adjust an irradiation point of a light source during exposure.
일반적으로, 음극선관은 열 전자를 집속 및 가속시켜 전자빔으로 형성시킴과 아울러 상기 전자빔으로 일정 형태로 순차 배열된 형광체를 발광시킴으로써 소정의 색상과 형상을 재현한다.In general, a cathode ray tube focuses and accelerates hot electrons to form an electron beam, and emits phosphors sequentially arranged in a predetermined form with the electron beam to reproduce a predetermined color and shape.
패널의 내면에 형광막을 형성하기 위해, R.G.B. 형광체 도포 및 노광과정을 거치게 되는데, 통상적인 노광장치는, 제3도에 도시한 바와 같이, 패널(P)이 안착된 베이스(50)와, 상기 베이스(50)의 내부에 순차적으로 설치된 필터(51)와 렌즈(52) 및 광원(53)을 포함한다. 광원(53)으로부터 방사되는 빛이 렌즈(52)와 필터(51)를 통과하므로써 패널(P)을 노광시키게 된다.In order to form a fluorescent film on the inner surface of the panel, R.G.B. Phosphor coating and exposure process, the conventional exposure apparatus, as shown in Figure 3, the panel 50 is mounted on the panel P, and the filter (sequentially installed inside the base 50) 51, a lens 52, and a light source 53. The light emitted from the light source 53 passes through the lens 52 and the filter 51 to expose the panel P.
광원(53)은 소정의 이동장치에 의해 R.G.B. 형광체 도포시 이동가능하도록 설치된다. 광원(53)은, 제4도에 도시한 바와 같은, 광원 커버(54)에 의해 외부가 차단되며, 광원 커버(54)에 형성된 투과공(55)에 의해 광원(53)의 조사점 형상이 결정된다. 따라서, 상기 투과공(55)의 형상에 따라 패널(P)에 조사되는 광원이 형상이 변화되므로써 패널(P)의 노광시 가장 적절한 형상의 광원을 조절하게 된다.The light source 53 is a R.G.B. It is installed to be movable when the phosphor is applied. As shown in FIG. 4, the outside of the light source 53 is blocked by the light source cover 54, and the shape of the irradiation point of the light source 53 is defined by the transmission hole 55 formed in the light source cover 54. Is determined. Therefore, the shape of the light source irradiated to the panel P is changed according to the shape of the transmission hole 55 to adjust the light source having the most appropriate shape when the panel P is exposed.
그러나, 상기한 바와 같은 음극선관용 노광장치에 있어서는, 광원(53)의 형상이 광원 커버(54)에 형성된 투과공(55)에 의해 결정되기 때문에, 광원(53)의 형상이 항상 일정한 형상으로 유지되므로써 일정 곡률로 형성되는 패널(P)의 각 부위에 적절하게 빛을 조사할 수 없게 되는 문제점이 있었다.However, in the exposure apparatus for cathode ray tubes as described above, since the shape of the light source 53 is determined by the transmission hole 55 formed in the light source cover 54, the shape of the light source 53 is always kept in a constant shape. Therefore, there was a problem in that light cannot be appropriately irradiated to each portion of the panel P formed with a constant curvature.
그러므로, 본 고안의 목적은 음극선관용 노광장치에서 광원의 형상이 광원커버에 형성된 투과공에 의해 하나로 한정되므로써 패널의 각 부위별로 적절한 빛의 조사를 할 수 없게 됨과 아울러 패널의 각 기종별로 각각의 광원 커버를 제작해야 하는 문제를 개선한 음극선관용 노광장치를 제공함에 있다.Therefore, the object of the present invention is that the shape of the light source in the exposure apparatus for cathode ray tube is limited to one by the through hole formed in the light source cover, so that appropriate light cannot be irradiated for each part of the panel and each light source for each model of the panel An object of the present invention is to provide an exposure apparatus for cathode ray tubes, which has improved the problem of manufacturing a cover.
상기 목적을 달성하기 위해, 본 고안은 패널이 안착된 베이스와, 상기 베이스의 내부에 순차적으로 설치된 필터와 렌즈 그리고 광원을 포함하는 음극선관용 노광장치에 있어서, 상기 광원에 2개로 분리 형성됨과 아울러 압축되면 투과공이 작아지고 확장되면 투과공이 커지도록 형성되며 각각 구동수단에 의해 슬라이드이동 가능하게 되는 한 쌍의 광원 커버를 설치하여 구성함을 특징으로 한다.In order to achieve the above object, the present invention is a cathode ray tube exposure apparatus comprising a base on which a panel is seated, a filter, a lens, and a light source sequentially installed in the base, wherein the light source is separated into two and is compressed. When the transmission hole is small and is enlarged when the transmission hole is enlarged, and characterized in that it is configured by installing a pair of light source cover which is slide-movable by each driving means.
이하, 첨부한 도면을 참조로 하여 본 고안의 바람직한 실시예를 상술하며, 도면 전체를 통하여 동일한 부분에는 동일한 도면부호를 사용하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the same reference numerals will be used for the same parts throughout the drawings.
제1도를 참조하면, 본 고안에 따른 광원 커버를 도시한 사시도를 도시하고, 제2(a)도에는 제1도의 광원 커버의 동작상태를 도시한 개략 평면도를 도시하며, 제2(b)도에는 본 고안에 따른 광원 커버가 음극선관용 노광장치에 설치된 상태를 나타내는 단면도를 도시한다.Referring to FIG. 1, a perspective view showing a light source cover according to the present invention is shown, and FIG. 2 (a) shows a schematic plan view showing an operating state of the light source cover of FIG. FIG. 10 is a sectional view showing a state in which a light source cover according to the present invention is installed in an exposure apparatus for cathode ray tubes.
본 고안에 따른 음극선관용 노광장치는 한 쌍의 광원 커버(1,2)를 포함하며, 각각의 광원 커버(1,2)는 대체로 'ㄷ'자의 형상을 취하게 된다. 하부 광원 커버(1)상에 상부 광원 커버(2)를 위치시킴으로써, 'ㄷ'자의 형상을 취하는 한 쌍의 광원 커버(1,2)의 상하부 벽은 서로 중첩되며, 서로 중첩되는 한 쌍의 광원 커버(1,2) 사이에는 정방형 또는 장방형 투과공(4)이 형성된다. 베이스(50)의 내부에서 베이스(50)의 바닥벽에는 지지벽(3)이 설치되고, 지지벽(3)에는 홈이 형성된다. 상기 한 쌍의 광원 커버(1,2)는 상기 홈에 슬라이딩 이동가능한 방식으로 끼워지며, 각각의 광원 커버(1,2)는 모터와 같은 적당한 구동수단에 의해 구동될 수 있게 된다.The exposure apparatus for cathode ray tubes according to the present invention includes a pair of light source covers 1 and 2, and each light source cover 1 and 2 generally takes the shape of a 'c'. By placing the upper light source cover 2 on the lower light source cover 1, the upper and lower walls of the pair of light source covers 1 and 2 taking the shape of 'c' overlap each other, and the pair of light sources overlap each other. A square or rectangular through hole 4 is formed between the covers 1 and 2. Inside the base 50, a support wall 3 is provided on the bottom wall of the base 50, and a groove is formed in the support wall 3. The pair of light source covers 1, 2 are fitted in a slidingly movable manner in the grooves, and each light source cover 1, 2 can be driven by a suitable driving means such as a motor.
각각의 광원 커버(1,2)의 상부벽과 하부벽 사이에 마련되는 공간의 높이는 서로 동일하게 된다(제2(a)도 참조). 그러므로, 모터와 같은 구동수단에 의해 2개의 광원 커버(1,2)가 슬라이딩 이동되면, 상기 한 쌍의 광원 커버(1,2) 사이에 마련되는 투과공(4)의 크기가 폭방향으로 조절될 수 있게 된다.The heights of the spaces provided between the upper wall and the lower wall of each light source cover 1, 2 are equal to each other (see also second (a)). Therefore, when the two light source covers 1 and 2 are slid and moved by a driving means such as a motor, the size of the transmission hole 4 provided between the pair of light source covers 1 and 2 is adjusted in the width direction. It becomes possible.
상기한 바와 같은 광원 커버(1,2)의 동작을 설명하면 제2(b)도에 도시한 광원(53)으로부터 빛이 발생됨과 아울러 렌즈(52)와 필터(51)를 통해 패널(P)을 노광시키게 되는 바, 패널(P)의 주변부에서는 상기 투과공(4)의 크기가 커져 보다 많은 빛을 패널(P)로 조사하게 되고 중앙부에서는 크기가 작아져 빛의 양을 적게 한다.Referring to the operation of the light source covers 1 and 2 as described above, light is generated from the light source 53 shown in FIG. 2 (b) and the panel P is provided through the lens 52 and the filter 51. As the light is exposed, the size of the through hole 4 increases at the periphery of the panel P to irradiate more light to the panel P, and at the center part to decrease the size of the light.
상기 빛의 조사량 조절은 2개의 광원 커버(1,2)가 중앙부로 모이면 투과공(4)이 작아지고 벌어지면 투과공(4)이 커짐을 이용한 것이다. 패널(P)의 중앙부에서 빛의 조사량을 줄이는 것은 패널(P)의 중앙부가 패널(P)의 주변부보다 많은 빛을 받을 수 있기 때문이다. 한 쌍의 광원 커버(1,2)는 실린더 등과 같은 구동수단에 의해서도 슬라이드 이동될 수 있게 된다.The irradiation amount of light is controlled by using two light source covers 1 and 2 as the central portion penetrates the through hole 4 and opens up the through hole 4. The amount of light emitted from the central portion of the panel P is reduced because the central portion of the panel P may receive more light than the periphery of the panel P. The pair of light source covers 1, 2 can also be slidably moved by a driving means such as a cylinder.
본 고안의 상기한 바와 같은 구성에 따라, 음극선관용 노광장치에서 광원 커버를 2개로 분리하여 형성함과 아울러 이를 각각 슬라이드이동 가능하게 구상하므로써 패널의 조사 위치에 따라 투과공의 크기를 조절하여 빛의 조사량을 임의적으로 조절 가능하게 되는 잇점이 발생된다.According to the configuration as described above of the present invention, by separating the light source cover into two in the cathode ray tube exposure apparatus and envisioning the slide movement respectively, by adjusting the size of the transmission hole according to the irradiation position of the panel An advantage arises in that the dose can be arbitrarily adjusted.
본 고안을 특정의 바람직한 실시예에 관련하여 도시하고 설명하였지만, 본 고안이 그에 한정되는 것은 아니고 이하의 실용신안등록청구의 범위에 의해 마련되는 본 고안의 정신이나 분야를 이탈하지 않는 한도내에서 본 고안이 다양하게 개조 및 변화될 수 있다는 것을 당 업계에서 통상의 지식을 가진 자는 용이하게 알 수 있다.Although the present invention has been illustrated and described with reference to certain preferred embodiments, the present invention is not limited thereto and is not limited to the spirit or field of the present invention provided by the scope of the following utility model registration claims. It will be readily apparent to one of ordinary skill in the art that the design can be modified and varied in a variety of ways.
