본 고안은 음극선관용 보강밴드에 관한 것으로 특히 보강밴드를 개선하여 대형구 제조시에 조립정도를 높이기에 적당하도록 한 것이다.The present invention relates to a reinforcing band for a cathode ray tube, in particular to improve the reinforcing band to be suitable for increasing the assembly degree when manufacturing a large sphere.

수상관용 음극선관의 구조는 제1도와 같이 전면 패널(1)과 후단훤넬(2)로서 프리트 접착되고 훤넬(2)의 후단에 전자빔을 발생시키는 전자총(3)을 갖는 구조로서 그 내부는 10 토르 정도의 고진공을 유지한 유리용기로 되어 있다.The structure of the cathode ray tube for a water tube is a structure having an electron gun (3) frit-bonded as a front panel (1) and a rear channel (2) and generating an electron beam at the rear end of the channel (2), as shown in FIG. It is a glass container that maintains a high degree of vacuum.

이러한 음극선관은 외부충격에 쉽게 파괴될 수 있는 단점이 있기 때문에 이를 보호하기 위한 수단을 필요로 한다.Such a cathode ray tube requires a means for protecting the cathode tube because it has a disadvantage of being easily destroyed by an external shock.

일반적으로 이러한 상태의 음극선관을 보강하는 방법으로는 제1도와 같은 음극선과의 전면 패널(1) 측면부를 띠상의 밴드로서 장력을 주어 묶은다음 체결하는 방법과, 전면 패널(1)의 주위에 수지를 부착한 림밴드로서 감싼다음 다시 그 위를 밴드로서 장력을 주어 묶는 방법 및 음극선관의 전면 패널(1) 외주보다 약간 작은 밴드(4)를 미리 준비하고 전술한 밴드를 가열, 신장시킨 다음 음극선관을 밴드에 삽입하여 이때 발생하는 금속의 쉴린케이지압을 이용하는 쉴린케이지 보강방법이 있다.In general, a method of reinforcing the cathode ray tube in such a state is a method of tightening and tightening a side portion of the front panel 1 with a cathode band as a band as shown in FIG. 1, and then tightening the resin around the front panel 1. Wrapped with a rim band attached and then tensioned on top of it as a band, and a band (4) slightly smaller than the outer circumference of the front panel (1) of the cathode ray tube was prepared in advance, and the band described above was heated and elongated. By inserting the tube into the band there is a method of reinforcing the shilin cage using the shilin cage pressure of the metal generated at this time.

종래의 칼라수상관 제조 공정은 제3도에 나타낸 바와 같이 ①패널부(1)의 형광면 도포공정(Screen) ②프릿백킹(prebaking) 공정 ③프리트 실링(Frit Sealing) 공정 ④건시일(Gun Seal) 및 익저스트(Exhaust) 공정 ⑤ 외장 흑연 도포 공정 다음에 ⑥ 밴드롤 본딩(bonding)하는 공정순으로 되어 있었다.As shown in FIG. 3, a conventional color water pipe manufacturing process is as follows: ① fluorescent surface coating process (screen) of panel portion (1) ② frit backing process (3) frit sealing process (4) Gun seal And the step (6) band roll bonding (Exhaust) step (5) followed by the exterior graphite coating step (6).

따라서 종래 수상관 제조공정시의 밴드를 본딩하는 보강공정은 제일 마지막에 공정이 이루어졌다.Therefore, the reinforcing step of bonding the band in the conventional water pipe manufacturing process was the last step.

그러나 최근의 대형구 제조시에 있어서는 그라스가 대형화 됨에 따른 응력문제 때문에 제3도의 프리베이크(prebake) 공정전에 밴드로 보강하는 제4도와 같은 제조방식이 많이 사용되고 있다.However, in the production of large-sized balls in recent years, the production method such as the fourth degree of reinforcing the band before the prebake process of FIG.

또한 프리트실링 공정에서는 제6도와 같은 프리트 홀더(Holder), (6)에서 패널(1)의 위치는 상측의 미오나이트(7)에 의해 결정되어 지는데 미오나이트(7)에 닿는 패널(1)의 위치는 제1도의 위치표시부(9)이고 훤넬(2)의 위치는 하측의 미오나이트(8)에 의해 결정되어진다.In the frit sealing process, the positions of the panel 1 in the frit holders and 6 as shown in FIG. 6 are determined by the upper myonite 7, but the panel 1 is in contact with the myonite 7. The position is the position display portion 9 of FIG. 1 and the position of the channel 2 is determined by the lower myonite 8.

이때의 훤넬(2)의 위치는 제1도의 패드(10)이다.The position of the channel 2 at this time is the pad 10 of FIG.

종래기술의 경우 패널(1)의 제5도와 같이 밴드(4)로 본딩(bonding)된 상태에서 프릿트실링(Frit Sealing)을 할 경우 패널(1)의 위치표시부(9)가 밴드(4)로 덮여지기 때문에 정확한 조정을 할 수 없으며 제5도와 같은 상태에서 보강밴드(4) 부분을 기준으로 할 경우 두께의 불균일로 인해 패널(1)과 훤넬(2)의 정확한 조립정도를 얻을 수 없다.In the prior art, when the frit sealing is performed in the state of bonding the band 4 to the band 4 as shown in FIG. 5 of the panel 1, the position display part 9 of the panel 1 is the band 4. Because it is covered with, it is impossible to make an accurate adjustment, and when the reinforcing band 4 part is referred to in the state as shown in FIG. 5, the assembly accuracy of the panel 1 and the channel 2 may not be obtained due to the thickness unevenness.

본 고안은 상기의 문제를 감안하여 이를 해소하고자 안출된 것으로서 보강밴드의 형상을 개선하여 패널의 정확한 위치에서 밴드를 체결하도록 하였다.The present invention was conceived to solve this problem in consideration of the above problems, and improved the shape of the reinforcing band to fasten the band at the correct position of the panel.

본 고안은 제4도와 같이 스크린⇒보강⇒프리베이크 프릿트시일 및 익저스트⇒외장흑연도포⇒CRT완성으로 되는 제조공정에 있어서, 보강밴드(14)의 형상을 제7도에서와 같이 종래의 보강밴드(4)에서 패널(1)의 위치표시부(9)에 대응되는 부위에 수직장공으로 된 위치표시공(14a)을 형성시켜서 되었다.In the manufacturing process of the screen ⇒ reinforcement ⇒ pre-baked frit seal and ulcer ⇒ exterior graphite coating ⇒ CRT completion as shown in Fig. 4, the shape of the reinforcing band 14 is conventionally reinforced as shown in FIG. In the band 4, the position display hole 14a which becomes a vertical hole was formed in the site | part corresponding to the position display part 9 of the panel 1, and was formed.

이와같은 본 고안은 상기 위치표시공(14a)을 형성시키므로 해서 프릿트시일(Frit Seal) 공정시 상기 패널(1)의 정확한 위치에 홀더(6)의 미오나이트(7)를 위치시킬 수가 있다.The present invention can form the position indication hole 14a so that the myonite 7 of the holder 6 can be positioned at the correct position of the panel 1 during the frit seal process.

패널(1)과 훤넬(2)이 융착되는 프릿트시일(Frit Sealing) 공정의 경우 훤넬(2)의 윗면(Seal 면)에 패널(1)과 훤넬(2)이 융착되도록 3-5㎜높이로 프릿트액을 입힌후 제6도와 같은 홀더(6)에 얹어 놓고 최고온도 약 450℃정도의 노에 통과시킨다.In the case of the frit sealing process in which the panel 1 and the channel 2 are fused, a height of 3-5 mm is applied so that the panel 1 and the channel 2 are fused to the upper surface of the channel 2 (seal). After applying the frit liquid, it is placed on the holder 6 as shown in FIG. 6 and passed through a furnace at a maximum temperature of about 450 ° C.

이 노를 통과하는 도중 훤넬(2) 윗면에 입혀진 프리트액이 녹아 결정화되면서 패널(1)과 훤넬(2)이 결합하게 된다.While passing through the furnace, frit liquor coated on the top of the channel 2 melts and crystallizes, thereby joining the panel 1 and the channel 2.

이때 패널(1)과 훤넬(2)이 융착되는 도중에 프리트액이 녹음으로 인해 패널(1)과 훤넬(2)쪽으로 약 2-3㎜ 내려오게 되며 따라서 제7도와 같이 보강밴드(14)의 위치표시공(14a) 형상을 수직쪽으로 약간 길게 해 줄 필요가 있다.At this time, while the panel 1 and the channel 2 are fused, the frit liquid comes down about 2-3 mm toward the panel 1 and the channel 2 due to the recording, and thus the position of the reinforcing band 14 as shown in FIG. It is necessary to lengthen the shape of the display hole 14a to the vertical direction slightly.

이렇게 프릿트시일된 브라운관은 제4도와 같이 봉지(Gun Seal)공정을 거치게 되는데 이때에도 음극선관을 잡아주는 기준은 패널(1)의 위치표시부(9)와 훤넬(2)의 패드(10)이므로 본 발명에 의한 보강밴드(14)로 작업을 할 경우 작업시간이 크게 단축되어 생산성이 향상되고 작업정도가 높게 된다.The frit-sealed CRT is subjected to a `` Gun Seal '' process as shown in FIG. 4, but the criterion for holding the cathode ray tube is the pad 10 of the position indicator 9 and the channel 2 of the panel 1. When working with the reinforcing band 14 according to the present invention, the working time is greatly shortened, productivity is improved, and the working degree is high.
