본 발명은 평면 브라운관의 새도우마스크 고정장치에 관한 것으로 특히 판넬에 일체로 형성된 레일에 새도우마스크를 고정시키는 것에 관한 것이다.The present invention relates to a shadow mask fixing device of a flat CRT, and more particularly, to fixing a shadow mask to a rail integrally formed in a panel.
종래의 평면 브라운관은 제1도와 같이 전면으로 방폭특성을 유지시키기 위하여 실리콘 밴드로 고정되어 있는 판넬(1)과, 상기 판넬(1)에 전면부가 융착되고 넥크부(3)가 일체로 형성된 펀넬(4)과, 상기 넥크부(3)에 봉입되어 R, G, B 3개의 전자비임(5)을 판넬(1)쪽으로 발사시키는 전자총(6)과, 상기 판넬(1)에는 공극 형상 또는 원형의 작은 구멍이 무수히 뚫린 새도우마스크(7)가 일정간격을 유지시키도록 지지시키는 레일(8)을 구성하였다.Conventional flat CRT has a panel (1) fixed with a silicone band to maintain the explosion-proof characteristics to the front as shown in FIG. 1, and a funnel in which the front part is fused to the panel (1) and the neck part (3) is integrally formed. 4), an electron gun 6 encapsulated in the neck portion 3 to shoot R, G, and B three electron beams 5 toward the panel 1, and the panel 1 has a void shape or a circular shape. The shadow mask 7 in which a number of small holes were drilled constituted a rail 8 for supporting a constant interval.
이와같이 형성된 평면브라운관의 판넬(1)에 레일(8)을 프리트 그라스(Frit glass)(9)로 접촉하여 고정하였다.The rail 8 was fixed to the panel 1 of the flat brown tube thus formed by contacting with frit glass 9.
이와같이 판넬(1)에 철판으로된 레일(8)을 프리트 그라스(9)로 부착함으로써 작업공정이 복잡할 뿐만 아니라 상기 레일(8)을 연마할 때 레일(8)이 철판이기 때문에 연마작업이 불편하였다.By attaching the rail 8 made of iron plate to the panel 1 in this way with the frit glass 9, the work process is not only complicated, but the polishing work is inconvenient because the rail 8 is iron plate when the rail 8 is polished. It was.
즉 종래에는 평면 브라운관의 새도우마스크와 새도우마스크를 판넬에 지지고 정하는 레일에 있어서, 새도우마스크를 레일에 고정시킬 때 새도우마스크를 레일에 용접고정시켰다. 그러기 위해서는 철제로 된 레일을 판넬에 부착하는 공정이 필요하고, 레일 연마작업이 불편하였으며, 또한 새도우마스크를 레일에 용접 고정시킴으로써 새도우마스크가 뒤틀리는 현상이 발생하는 등 문제점이 발생하였다.That is, conventionally, in a rail for holding and fixing a shadow mask and a shadow mask of a flat CRT on a panel, the shadow mask is welded to the rail when the shadow mask is fixed to the rail. To this end, a process of attaching iron rails to the panel is required, and rail grinding is inconvenient, and shadow masks are distorted by welding and fixing the shadow masks to the rails.
본 발명은 이러한 점을 감안하여 제안한 것으로써 판넬에 레일을 일체로 형성하고 상기레일에 새도우마스크를 부착함으로써 평면브라운관의 제조를 용이토록 하는데 그 목적이 있다.The present invention has been made in view of this point, and has an object of facilitating the manufacture of a flat brown tube by forming a rail integrally on a panel and attaching a shadow mask to the rail.
본 발명 평면 브라운관의 새도우마스크 고정장치를 제2도에 의하여 설명하면 다음과 같다.Referring to FIG. 2, the shadow mask fixing device of the present invention flat CRT is as follows.
판넬(101)에 일체로 성형된 레일(102)과, 상기 레일(102)을 일정 규격으로 연마한 면에 접착제로 부착한 새도우마스크(103)와, 상기 새도우마스크(103)의 가장자리가 판넬(101)과 펀넬(104)의 접착부(105)에 접착되어 고정되도록 하였다.The rail 102 integrally formed on the panel 101, the shadow mask 103 attached with an adhesive to the surface of the rail 102 polished to a predetermined standard, and the edges of the shadow mask 103 have a panel ( 101) and the adhesive portion 105 of the funnel 104 to be fixed.
즉 본 발명은 판넬(101)에 일체로 성형된 레일(102)을 이용하고, 새도우마스크(103)를 레일면에 접착제로 부착하고, 새도우마스크(103)의 가장자리를 판넬(101)과 펀넬(104)의 접착부에 접착되게 고정시킨다. 좀더 상세히 설명하면 판넬(101)과 같은 재질인 유리로 레일(102)을 판넬(101)에 일체로 형성시키고, 새도우마스크(103)가 레일(102)에 접착되는 부분에는 제3도와 같이 새도우마스크가 접착이 잘 되도록 새도우마스크상의 레일이 접착되는 부분에 유공부(106)를 확장구비하고, 새도우마스크(103)의 가장자리는 판넬(101)과 펀넬(104)이 접착되는 부분에 고정시킨다.That is, the present invention uses the rail 102 integrally molded to the panel 101, attaches the shadow mask 103 to the rail surface with an adhesive, and the edges of the shadow mask 103 to the panel 101 and the funnel ( And securely adhere to the bonding portion of 104). In more detail, the rail 102 is integrally formed on the panel 101 with glass made of the same material as the panel 101, and the shadow mask 103 is bonded to the rail 102 with the shadow mask as shown in FIG. The hole 106 is expanded and provided to the part to which the rail on the shadow mask is bonded so that the adhesive is well adhered, and the edge of the shadow mask 103 is fixed to the part to which the panel 101 and the funnel 104 are bonded.
이와같이 새도우마스크(103)가 고정되는 본 발명은 판넬(101)에 레일(102)을 접착제로 부착하는 공정으로 종래의 새도우마스크를 레일에 용접하던 공정을 제외시킬 수 있기 때문에 판넬(101)의 제조가 간편하다.As such, the present invention in which the shadow mask 103 is fixed is a process of attaching the rail 102 to the panel 101 with an adhesive so that the process of welding the conventional shadow mask to the rail can be excluded. Is simple.
그리고, 판넬(101)에 일체로 성형된 레일(120)이 판넬(101)과 일체인 유리로 성형되어져 있기 때문에 종래와 같이 철재로된 레일을 연마하는 것보다 연마작업이 잘 이루어진다.In addition, since the rail 120 integrally formed on the panel 101 is formed of glass integrated with the panel 101, the polishing operation is better than that of the conventional rail rail.
그리고, 종래와 같이 레일에 새도우마스크를 부착함에 있어서 용접하는 것을 제외시킴으로써 작업공정상의 복잡성도 해결하고, 용접으로 인한 새도우마스크가 뒤틀리는 현상등을 방지할 수 있은 발명이다.In addition, by removing the welding in attaching the shadow mask to the rail as in the prior art, the complexity of the work process is also solved, and the phenomenon in which the shadow mask is distorted due to welding is prevented.
