본 발명은 평면브라운관의 새도우마스크 고정장치에 관한 것으로 특히 판넬의 제작이 용이하고 판넬에 새도우마스크를 간편하게 부착할 수 있도록 한 것이다.The present invention relates to a shadow mask fixing device of a flat brown tube, in particular to facilitate the manufacture of the panel and to easily attach the shadow mask to the panel.
종래 평면브라운관의 새도우마스크 고정장치를 제1도에 의하여 설명한다.The shadow mask fixing device of the conventional flat brown tube is described with reference to FIG.
전면으로 방폭특성을 유지시키기 위하여 방폭유리(2)를 부착한 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 다수개 뚫린 새도우 마스크(7)가 일정간격을 유지시키도록 지지시키는 레일(8)을 구성하였다.In order to maintain the explosion-proof characteristics in the front surface of the panel (1) attached to the explosion-proof glass (2), the front panel is fused to the panel (1) and the neck portion (3) integrally formed with the neck (3) and the neck portion ( 3) an electron gun (6) enclosed in 3) to fire the three RGB electron beams (5) toward the panel (1), and the panel (1) has a shadow mask (7) in which a plurality of voids or circular small holes are drilled. The rail 8 which supports to maintain a fixed space | interval was comprised.
이와같이 형성된 평면브라운관의 판넬(1)에 레일(8)을 프리트그라스(Frit glass)(9)로 접착하여 고정하였다.The rail 8 was attached to the panel 1 of the flat brown tube formed as described above and fixed with frit glass 9.
그러나 이러한 종래의 브라운관은 새도우마스크를 일정간격으로 유지하기 위하여 레일을 일정 두께로 만들기 위해 연마 작업을 함으로써 연마작업시 일정두께를 유지하기 힘들고, 레일의 주성분이 철판으로 구성되어 있어 브라운관에 열처리를 할 경우 판넬(1)과 레일(8)의 열 팽창계수가 서로 상이하여 판넬(1)의 힘이 발생함으로써 전자빔(5)의 원래 위치가 아닌 서로 다른 지점에 방사되어 형광체를 발광시켜 타색 불량을 발생시키는 문제점이 발생되었다.However, such a conventional CRT is difficult to maintain a constant thickness during polishing by grinding the rail to a certain thickness in order to maintain the shadow mask at a predetermined interval, and the main component of the rail is made of iron plate, so that the CRT can be heat treated. In this case, the thermal expansion coefficients of the panel 1 and the rail 8 are different from each other, so that the force of the panel 1 is generated, which is radiated to different points instead of the original positions of the electron beams 5 to emit phosphors, thereby causing other color defects. A problem has arisen.
본 발명은 상기 문제점을 해결하고자 레일의 재질을 판넬의 재질과 동일한 유리(Glass)로 함으로써 판넬 가공시 일정두께를 만들어 성형할 수 있으므로 연마작업의 불편을 해소할 수 있고, 또한 판넬과 열팽창 계수가 동일한 유리 재질을 사용함으로써 열처리시 판넬의 휨을 방지할 수 있어 전자빔 방사시 타색 불량을 방지하도록 함을 그 목적으로 한다.In order to solve the above problems, the rail material is made of the same glass as that of the panel, so that a certain thickness can be formed during panel processing, thereby eliminating the inconvenience of polishing, and the panel and the coefficient of thermal expansion. By using the same glass material, the panel can be prevented from warping during heat treatment, and the purpose is to prevent other color defects during electron beam radiation.
본 발명에 의한 평면브라운관의 새도우마스크 고정장치를 첨부된 제2도 내지 제3도의 도면에 의하여 상세히 설명한다.The shadow mask fixing device of the flat brown tube according to the present invention will be described in detail with reference to the accompanying drawings.
판넬(101)에 일체로 성형된 레일(102)과, 상기 레일(102)에 새도우마스크(103)를 용접에 의하여 고정하는 고정수단을 구비하였다.A rail 102 integrally formed on the panel 101 and fixing means for fixing the shadow mask 103 to the rail 102 by welding.
그리고, 상기 고정수단은 레일(102)에 형성된 턱부(102')와, 상기 턱부(102')에 삽입되는 삽입홈(104)이 형성된 프레임(105)과, 상기 프레임(105)에 새도우마스크(103)를 용접하여 고정하였다.The fixing means includes a jaw portion 102 'formed on the rail 102, a frame 105 having an insertion groove 104 inserted into the jaw portion 102', and a shadow mask on the frame 105. 103) was fixed by welding.
상기 프레임(105)위에 새도우마스크(103)를 80% 정도 탠션(Tension)을 인가한 상태에서 용접한 후 새도우마스트(103)가 용접된 프레임(105)을 20% 탠션을 추가 인가하여 패널(101)의 턱부(102')와 결합시켰다.After the shadow mask 103 is welded on the frame 105 in a state in which a tension is applied about 80%, the panel 101 is further applied by applying 20% tension to the frame 105 to which the shadow mask 103 is welded. Jaw portion 102 ').
이와 같이 구성된 본 발명을 구체적으로 설명하면, 판넬(101)을 성형할 때 레일(102)이 일체로 성형되게 함으로써 종래와 같이 성형된 판넬에 레일을 프리트 그라스(Frit glass)로 접착하여야 하는 공정을 제외시킬 수 있기 때문에 판넬(101)의 제조공정이 단조로워 지기 때문에 판넬(101)의 제조가 용이하다.The present invention configured as described above will be described in detail. In this case, when the panel 101 is molded, the rail 102 is integrally molded so that the rail is adhered to frit glass by the glass. Since the manufacturing process of the panel 101 can be forged because it can be excluded, the manufacturing of the panel 101 is easy.
또한, 본 발명은 레일(102)이 판넬(101)과 같은 재질이면서 일체로 성형되어 재질이 유리이기 때문에 레일(102)의 연마작업이 종래것에 비하여 작업이 간편하다.In addition, since the rail 102 is made of the same material as the panel 101 and integrally molded and made of glass, the rail 102 is more easily polished than the conventional one.
그리고, 본 발명은 판넬(101)에 일체로 성형된 레일(102)의 턱부(102')에 프레임(105)의 삽힙홈(104)을 삽입하여 프레임(105)을 레일(102)에 고정함으로써 종래와 같이 판넬에 레일을 프리트그라스로 접착하는 공정보다 작업이 훨씬 편리한 것이다.In addition, the present invention inserts the insertion groove (104) of the frame 105 into the jaw portion (102 ') of the rail 102 integrally formed in the panel 101 by fixing the frame 105 to the rail 102 As in the prior art, the operation is much more convenient than the process of bonding the rail to the panel with frittgrass.
이와 같이 본 발명은 종래것에 비하여 판넬이 제조가 용이하고 또한 레일의 구성 및 새도우마스크의 고정이 편리한 것으로써 작업공정을 줄여 생산가를 낮출 수 있는 유익한 발명이다.As described above, the present invention is an advantageous invention that the panel is easy to manufacture and the rail structure and the fixing of the shadow mask are convenient as compared with the conventional ones, thereby reducing the production process by reducing the work process.
