Abstract
본 고안은 개선된 칼라 음극선관용 봉착홀더를 개시한다.The present invention discloses an improved sealing holder for color cathode ray tubes.
종래에는 패널과 펀넬을 각각 지지하는 두 스토퍼가 전용 조절나사에 의해 독립조정되었으므로 조절작업이 어려울 뿐 아니라 자칫 양자가 어긋날 우려가 많았다.In the past, the two stoppers supporting the panel and the funnel, respectively, were independently adjusted by dedicated adjusting screws.
본 고안에서는 상호 연결되어 두 스토퍼에 동축으로 접촉하는 두 안내봉을 한 조절나사로 조정함으로써, 간단하면서도 패널과 펀넬을 정확히 정합 지지할 수 있도록 하였다.In the present invention, two guide rods which are interconnected and coaxially contact the two stoppers are adjusted with one adjusting screw, so that the panel and the funnel can be precisely matched.

본 고안은 칼라 음극선관(color 陰極線官) 제조에 관한 것으로, 더 상세히는 패널(panel)과 펀넬(funnel)을 봉착(sealing)하기 위해 지지하는 홀더(holder)에 관한 것이다.The present invention relates to the production of color cathode ray tubes, and more particularly, to a holder for sealing a panel and a funnel.
칼라 음극선관은 흑백 음극선관과는 달리 섀도우마스크(shadow mask)등의 각종 기공부품(機工部品)을 구비하므로 패널과 펀넬로 분리 제조된 뒤, 패널에 기공부품들을 장착하고 펀넬과 결합하여 구성된다. 이들의 결합방법으로는 펀넬의 시일면 (seal face)에 결정성 분말유리인 프리트 글레스(frit glass)를 도포하고, 이에 패널을 얹어 건조한 뒤 소성함으로써 용융 접합시키는 방법이 일반적으로 사용된다.Unlike black and white cathode ray tubes, colored cathode ray tubes have various pore parts such as shadow masks, so they are manufactured separately from panels and funnels, and then the pores are mounted on the panels and combined with the funnels. . As a bonding method of these, a method in which a fused glass, which is crystalline powder glass, is applied to a seal face of a funnel, and a panel is placed on it, dried and calcined, is then melt-bonded.
제1도에는 이와같은 봉착공정에서 패널과 펀넬을 지지하는 종래의 벌브홀더(1)를 개략적으로 도시하였다. 이것은 소정각도로 기울어진 L자형의 프레임(frame: 2)상에 복수의 지지블럭(支持 block: 3)이 설치되고, 각 지지블럭(3)의 삽입구멍(3a)에는 패널(P)과 펀넬(F)의 측면을 각각 접촉지지하는 두 스토퍼(stopper: 4)가 이동 가능하게 설치된다. 또한 지지블럭(3)에는 두 스토퍼(4)의 후단에 접촉하여 그 상대위치를 조절하는 조정나사(5)가 각각 나사결합된다. 한편 스토퍼(4)는 전열에 의한 크랙(crack)방지를 위해 열전도율이 매우 낮은 재질로 구성된다.FIG. 1 schematically illustrates a conventional bulb holder 1 supporting a panel and a funnel in such a sealing process. This is provided with a plurality of support blocks 3 on an L-shaped frame 2 inclined at a predetermined angle, and a panel P and a funnel in the insertion hole 3a of each support block 3. Two stoppers 4 each supporting the side surfaces of F are movable. In addition, the support block 3 is screwed in each of the adjustment screw (5) for contacting the rear ends of the two stoppers (4) to adjust their relative positions. On the other hand, the stopper 4 is made of a material having a very low thermal conductivity in order to prevent cracking by heat transfer.
그런데 이러한 종래의 봉착홀더(1)는 패널(P)과 펀넬(F)을 지지하는 두 스토퍼가 상호 분리되어 각각의 조정나사(5)에 의해 개별 동착하므로 패널(P)과 펀넬(F)을 정합(alignment)시키기가 대단히 어려울 뿐 아니라 조정작업도 번잡한 문제가 있었다. 이에 따라 점선으로 도시한 바와같이 패널(P)과 펀넬(F)이 어긋날 우려가 매우 많았으며, 이 경우 화면중심과 전자총 중심이 불일치되어 화질이 저하될 뿐 아니라 심하면 소성과정에서 어긋난 부위에 응력이 집중되어 후속되는 배기(排氣)과정에서 폭축(implosion)을 야기시키게 된다.However, in the conventional sealing holder 1, the two stoppers for supporting the panel P and the funnel F are separated from each other and individually fitted by the respective adjusting screws 5, so that the panel P and the funnel F are separated. Not only is it very difficult to align, but there are also troublesome adjustments. As a result, as shown by the dotted line, the panel P and the funnel F are very likely to be misaligned. In this case, the center of the screen and the electron gun are inconsistent and the image quality is degraded. It is concentrated and causes an implosion in the subsequent exhaust process.
본 고안은 상술한 종래의 문제들을 감안하여 패널과 펀넬을 정확히 정합시켜 지지할 수 있는 칼라 음극선관의 봉착홀더를 제공하는 것이다.The present invention is to provide a sealing holder of a color cathode ray tube that can accurately support the panel and the funnel in view of the above-described conventional problems.
이와같은 목적을 달성하기 위해 본 고안에 의한 칼라 음극선관의 봉착홀더는 프리트가 도포된 패널과 펀넬의 측면을 각각 접촉 지지하는 지지블럭을 구비하는 칼라 음극선관용 봉착홀더에 있어서, 상호 연결되어 지지블럭에 함께 이동가능하게 설치되며 복수의 스토퍼 후단에 각각 접촉하는 복수의 안내봉과, 복수의 안내봉을 지지블럭에 대해 상대이동시키는 조절나사를, 구비하는 것을 특징으로 한다.In order to achieve the above object, a sealing holder of a color cathode ray tube according to the present invention is a sealing holder for a color cathode ray tube having a frit coated panel and a support block for contacting and supporting the sides of the funnel, respectively. And a plurality of guide rods installed to be movable together and contacting the rear ends of the plurality of stoppers, and an adjustment screw for relatively moving the plurality of guide rods with respect to the support block.
이에 따라 본 고안은, 패널과 펀넬을 정확히 정합시킨 상태로 지지할 수 있게 되므로 음극선관의 제조불량률 감소와 화질향상등에 기여하게 된다.Accordingly, the present invention can support the panel and the funnel in a state where it is accurately matched, thereby contributing to the reduction of manufacturing defect rate of the cathode ray tube and the improvement of image quality.
이하 첨부된 도면을 참조하여 본 고안의 한 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제2도에서, 본 고안에 의한 칼라 음극선관용 봉착홀더(11)는 소성로내의 이동시 진동등에 의한 패널(P)과 펀넬(F)의 어긋남을 방지하기 위해 프레임(12)이 소정각도로 기울어지게 설치된다. 프레임(12)상에는 복수의 지지블럭(13)이 소정위치에 배열되고, 이 지지블럭(13)의 소정위치에는 두 삽입구멍(13a)이 형성되어 패널(P)과 펀넬(F)의 측면을 각각 접촉 지지하는 두 스토퍼(14)를 이동가능하게 삽입한다.In FIG. 2, the sealing holder 11 for the color cathode ray tube according to the present invention is installed so that the frame 12 is inclined at a predetermined angle to prevent misalignment of the panel P and the funnel F due to vibration or the like during movement in the kiln. do. On the frame 12, a plurality of support blocks 13 are arranged at predetermined positions, and two insertion holes 13a are formed at predetermined positions of the support blocks 13 to form side surfaces of the panel P and the funnel F. Two stoppers 14, which are in contact with each other, are movably inserted.
본 고안의 특징에 따라 지지블럭(13)에는 두 스토퍼(14)의 후단에 각각 접촉하는 두 지지봉(16)이 한 지지판(15)에 의해 상호 연결되어 스토퍼(14)와 동축으로 함께 이동되도록 설치된다. 지지블럭(13)의 두 삽입구멍(13a) 사이의 중간에는 나사구멍(13b)이 형성되어 지지판(15)을 지지블럭(13)에 대해 상대 이동시키는 조절나사(17)가 결합된다. 이에따라 조절나사(17)는 바람직하기로 지지판(15)과 공회전가능하게 결합된다.According to a feature of the present invention, the support block 13 is installed such that two support rods 16 respectively contacting the rear ends of the two stoppers 14 are interconnected by one support plate 15 to be moved coaxially with the stopper 14. do. In the middle between the two insertion holes 13a of the support block 13, a screw hole 13b is formed, and an adjustment screw 17 for moving the support plate 15 relative to the support block 13 is coupled. Accordingly, the adjustment screw 17 is preferably coupled to the support plate 15 to be idling.
이와같이 구성된 본 고안 봉착홀더(11)는 조절나사(17)를 정,역 회전시킴에 딸라 지지판(15)으로 연결된 두 안내봉(16)이 지지블럭(13)에 대해 함께 전진 또는 후진하게 되므로 두 스토퍼(14)가 동시에 같은 범위로 동작되게 된다. 이에따라 패널(P)과 펀넬(F)을 어긋남 없이 정확히 정합시킬 수 있다.The sealing holder 11 of the present invention configured as described above has two guide rods 16 connected to the support plate 15 by rotating the adjusting screw 17 forward and backward, so that the two guide rods 16 move forward or backward together with respect to the support block 13. The stopper 14 is operated in the same range at the same time. Accordingly, the panel P and the funnel F can be accurately matched without misalignment.
이와같이 본 고안에 의하면, 패널과 펀넬을 정확히 정합시켜 지지할 수 있으므로 전자총과 화면중심의 정합이 보장되고 조절작업도 매우 간단해 진다. 따라서 본 고안은 칼라 음극선관의 제조불량률 감소와 화질 및 품위향상에 큰 효과가 있다.Thus, according to the present invention, since the panel and the funnel can be accurately matched and supported, the match between the electron gun and the screen center is ensured, and the adjustment work is very simple. Therefore, the present invention has a great effect on reducing the manufacturing defect rate of the color cathode ray tube and improving the image quality and quality.
