본 고안은 평면브라운관의 레일구조에 관한 것으로 특히 새도우마스크의 인장력에 따라 레일이 변형되는 것을 방지할 수 있도록 한 것이다.The present invention relates to a rail structure of a flat brown tube, in particular, to prevent the rail from being deformed according to the tension of the shadow mask.
종래의 평면브라운관은 제1도와 같이 전면으로 방폭특성을 유지시키기 위하여 실리콘밴드로 고정되어 있는 판넬(1)과, 상기 판넬(1)에 전면부가 융착되고 넥크부(3)가 일체로 형성된 판넬(4)과, 상기 넥크부(3)에 봉입되어 R.G.B 3개의 전자빔(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 유지하도록 지지시키는 레일(8)을 구성하였다.Conventional flat brown tube is a panel (1) is fixed with a silicon band in order to maintain the explosion-proof characteristics to the front as shown in Figure 1, the front panel is fused to the panel (1) and the neck portion (3) integrally formed panel ( 4), an electron gun 6 encapsulated in the neck portion 3 for firing three electron beams 5 of RGB toward the panel 1, and the panel 1 has numerous holes or voids in the shape of a void. A rail 8 supporting the shadow mask 7 to maintain a constant interval was configured.
상기 레일(8)은 판넬(1)에 프리트그라스(frit glass)(9)를 이용하여 접착 고정하였다.The rail 8 was adhesively fixed to the panel 1 using frit glass 9.
그리고, 상기 레일(8)을 연마한 후 새도우마스크(7)를 용접하여 고정하였다.After the rail 8 was polished, the shadow mask 7 was welded and fixed.
이와같이 구성된 상태에서 전자총(6)에서 방사되어 나온 전자빔(5)은 새도우마스크(7)의 마스크 구멍을 통과하여 판넬(1)내면에 도포되어진 형광체에 충돌한다. 그리고 충돌된 전자빔(5)의 운동에너지는 형광체를 발광시켜 화상을 재현하게 되는데, 이때 새도우마스크(7)의 전자빔 통과공을 통과하는 전자빔은 전체 전자빔의 약 20%에 불과하고 나머지는 새도우마스크(7)에 충돌하여 열로 변환되며 이 열에 의하여 새도우마스크(7)가 열팽창하게 되는 도밍현상이 야기된다.In this configuration, the electron beam 5 emitted from the electron gun 6 passes through the mask hole of the shadow mask 7 and impinges on the phosphor applied to the inner surface of the panel 1. The kinetic energy of the collimated electron beam 5 emits a phosphor to reproduce an image. At this time, the electron beam passing through the electron beam passing hole of the shadow mask 7 is only about 20% of the total electron beam, and the rest is shadow mask ( 7) is converted into heat, which causes a doming phenomenon in which the shadow mask 7 thermally expands.
그래서 상기 도밍 현상을 해결하기 위해서 최근에는 텐션마스크(Tension Mask)를 사용하는데, 텐션마스크는 강제적으로 인장시켜 마스크에 인장력을 인가시켜 놓았기 때문에 전자의 충돌로 발생하는 마스크의 열팽창을 강제적으로 인가한 기구적인 장력으로 대처하므로 높은 온도에서도 마스크에 형성시킨 홀의 위치를 변화시키지 않는다.In order to solve the dominant phenomenon, a tension mask has recently been used. Since the tension mask is forcibly tensioned to apply a tensile force to the mask, the thermal expansion of the mask caused by the collision of electrons is forcibly applied. It copes with mechanical tension and does not change the position of the holes formed in the mask even at high temperatures.
또한 종래의 레일은 레일(8)의 전체적인 형상이 제2도에서와 같이 각변이 직선으로 이루어져 새도우마스크(7)가 판넬(1)에 일정간격을 유지시키도록 지지하고 있다.In addition, in the conventional rail, the overall shape of the rail 8 is formed in a straight line as shown in FIG. 2 so that the shadow mask 7 supports the panel 1 to maintain a constant distance.
그리고 마스크는 인장되어 상기 레일에 용접되어진다. 이때 새도우마스크(7)는 용접된 레일(8)에서 힘(F)으로 레일을 당기게 된다. 이때 프리트그라스(9)의 지지가 약하면, 판넬로부터 이탈하게 된다(제3도 참조). 상기 레일(8)은 프리트그라스(9)에 의해서 판넬(1)에 고정되고, 레일(8)의 위에는 새도우마스크(7)가 인장되어 용접고정된다. 레일(8)에 새도우마스크(7)가 용접고정될 때 새도우마스크(7)가 인장되어 있기 때문에 제3도에 나타낸 바와 같이 마스크가 용접되어진 레일면에 힘(F)이 작용된다.The mask is then tensioned and welded to the rail. At this time, the shadow mask 7 is pulled by the force (F) in the welded rail (8). At this time, if the support of the frit glass 9 is weak, it is separated from the panel (see FIG. 3). The rail 8 is fixed to the panel 1 by fritgrass 9, and the shadow mask 7 is tensioned and welded on the rail 8. Since the shadow mask 7 is tensioned when the shadow mask 7 is fixed to the rail 8 by welding, the force F is applied to the rail surface to which the mask is welded as shown in FIG.
상기 힘(F)이 레일(8)을 판넬에 부착시키는 프리트그라스(9)의 부착력보다 강하면 레일이 판넬로부터 이탈하여 불량이 발생한다.If the force F is stronger than the adhesive force of the fritgrass 9 attaching the rail 8 to the panel, the rail is separated from the panel and a failure occurs.
본 고안은 상기의 문제점을 해결하기 위해서 레일(8)을 충분히 고정시킬 수 있도록 접착면을 증가시키는 방법과 가해지는 힘(F)의 분포를 넓게 하는 방법을 동시에 만족시킬 수 있는 구조로 레일의 전체 형상을 형성하고 있다.In order to solve the above problems, the present invention has a structure that can satisfy both the method of increasing the adhesive surface to widen the rail 8 sufficiently and the method of widening the distribution of the applied force (F) at the same time. It forms a shape.
즉, 제4도와 같이 레일(102)의 각변을 종래(제2도의 8)의 직선 형상과는 달리 원호를 갖는 형상을 갖게 함으로서 레일(8)을 고정시킬 수 있는 접착면의 전체 넓이가 증가되고, 레일(102)위에 인장되어 용접되어있는 새도우마스크가 가하는 힘(F)과 반대방향으로 레일의 형상(레일의 각변을 바깥쪽으로 원호를 갖는 형상)을 형성함으로써 상기 힘(F)의 분포를 넓힐 수 있다.That is, as shown in FIG. 4, the overall width of the adhesive surface to which the rail 8 can be fixed is increased by making the sides of the rail 102 have a circular arc shape, unlike the linear shape of the conventional (8 in FIG. 2). , The distribution of the force (F) is broadened by forming the shape of the rail (a shape having an arc of each side of the rail outward) in a direction opposite to the force (F) applied by the shadow mask that is tensioned and welded on the rail (102). Can be.
따라서 레일의 판넬에 고정하고 있는 프리트그라스에 가해지는 전단력이 접착력보다 크게 되는 것을 방지하여 레일이 판넬로부터 이탈되는 것을 방지할 수 있다.Therefore, the shear force applied to the frit glass fixed to the panel of the rail can be prevented from becoming larger than the adhesive force, thereby preventing the rail from being separated from the panel.
