본 고안은 브라운관에 있어서 전자총을 지지한 유리스템과 네크사이를 봉합하는 방법의 개선에 관한 것이다.The present invention relates to an improvement of the method of sealing between the glass stem supporting the electron gun and the neck in a CRT.

브라운관은 제1도에서 보는 바와 같이 판넬(PANEL)(1) 훤넬(FUNNEL)(2), 네크(NCCK)(3)의 조합구성으로 몸통이 이루어지고, 이 몸총의 네크(3) 내부에 유리 스템(4)에 지지된 전자총(5)을 삽입설치한 후 상기 네크(3)의 단부 및 스템(4) 사이를 봉합밀봉하여 완성되어진다.As shown in Fig. 1, the CRT is made of a combination of a panel (1), a panel (FUNNEL), and a neck (NCCK) (3), and the glass is inside the neck (3) of the body. After inserting and installing the electron gun 5 supported on the stem 4, it is completed by sealing-sealing between the end of the neck 3 and the stem 4.

이러한 브라운관의 제작에 있어서 종래에는 가열토오치(6)와 같은 수단을 사용하여 브랑운관의 네크(3)와 스템(4)간의 봉합부위를 직접 가열융착시켜 봉합토록 하는 방법을 써 왔는바, 이와 같은 종래의 전자총 봉합 방법은 상기 네크(3) 및 스텝(4)이 변형, 편위되기 쉬워 전자총의 설치불량을 초래하게 되는 문제점이 있었다.In the manufacture of such CRT, conventionally, a method of heating the heat-sealed portion between the neck 3 and the stem 4 of the Brunn tube using a means such as a heating torch 6 has been used. The conventional electron gun sealing method has a problem in that the neck 3 and the step 4 are easily deformed and biased, resulting in a poor installation of the electron gun.

본 발명은 이러한 종래의 문제점을 매우 효과있게 해소하면서 브라운관 제작공정 간소화 및 비용절감에 크게 기여할 수 있도록 안출된 새롭고 유용한 전자총 봉합방법인 것으로, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is a novel and useful electron gun sealing method devised to contribute greatly to the simplification and cost reduction of the CRT manufacturing process while effectively solving the conventional problems, which will be described in detail based on the accompanying drawings.

즉, 본 발명에 따른 브라운관의 전자총 봉합방법은 제2도, 제3도에 도시된 바와 같이 해당 브라운관의 네크(3)와 스텝(4)사이를 이들 사이에 프리트 글라스(FRIT GLASS)(7)를 개재시켜 조립고정한 후 이 프리트 글라스(7)의 용융접합에 의해 네크(3)와 스텝(4) 사이의 봉합을 이루도록 하는 것을 특징으로 하는 것이 바람직한 실시예에 있어서, 상기 프리트 글라스(7)는 해당 브라운관의 판넬(1) 및 훤넬(2)간의 봉합에 사용되는 통상의 프리트 글라스(8)와 동일유사한 것을 사용토록 하고, 이 브라운관을 제2도에 도시된 양태로 픽스쳐(9)에 고정시켜 통상적인 판넬-훤넬 봉합로를 통과시킬 때 상기 프리트 글라스(7)(8)의 융착에 의한 네크(3)와 스텝(4) 사이의 봉합 및 판넬(1)과 훤넬(2) 사이의 봉합이 동시에 이루어지게 하는 것이 매우 유리하다.That is, the electron gun sealing method of the CRT according to the present invention is a frit glass (FRIT GLASS) (7) between the neck (3) and step (4) of the CRT as shown in Figs. In the preferred embodiment of the present invention, the frit glass 7 is sealed between the neck 3 and the step 4 by melt bonding of the frit glass 7. An analogous to the common frit glass 8 used for sealing between the panel 1 and the channel 2 of the CRT is used, and the CRT is fixed to the fixture 9 in the form shown in FIG. When passing through a conventional panel-channel suture, the sealing between the neck 3 and the step 4 by fusion of the frit glass 7 and 8 and the sealing between the panel 1 and the channel 2 It is very advantageous to make them at the same time.

상기에서 네크(3)와 스텝(4)이 조립된 외측에는 이들간의 조립위치를 안정적으로 고정유지시킬 수 있는 적정의 고정구(10)가 씌워져 설치될 수 있다.In the above, the neck 3 and the step 4 may be installed on the outer side where the appropriate fastener 10 can be installed to stably hold the assembly position therebetween.

이와 같은 본 발명의 봉합방법은 종래와 같이 네크(3)와 스텝(4)을 직접 가열 융착시켜 봉하하는것이 아니라 상기 네크(3) 및 스텝(4)의 취약화 내지는 변형, 손상을 초래하지 않는 비교적 저온에서 프리트 글라스(7)만 융착시켜 목적하는 바의 전자총 봉합을 간편히 이루어낼 수 있도록 되어 있기 때문에 종래에 이러한 전자총 봉합공정에서 빈발하였던 브라운관 네크부의 취약화 및 스텝의 변형, 편위로 인한 전자총의 설치불량을 완전해소할 수 있고, 또 상기 전자총의 봉합공정은 기존의 판넬-훤넬 봉합설비를 이용하여 전자총 봉합공정시 함께 동시에 이루어지게 할 수 있어 이를 위한 별도의 설비와 동력제공 및 시간소요가 필요없으므로 관련 브라운관의 제작공정을 더욱 간소 효율화할 수 있고 비용도 크게 절감할 수 있게 된 뛰어난 장점을 지닌 것이다.The sealing method of the present invention does not directly seal and seal the neck 3 and the step 4 as in the related art, but does not cause the weakening, deformation, or damage of the neck 3 and the step 4. Since only the frit glass 7 is fused at a relatively low temperature, the electron gun can be easily sealed as desired. Installation defects can be completely eliminated, and the sealing process of the electron gun can be simultaneously performed during the sealing process of the electron gun by using the existing panel-channel sealing equipment, which requires separate equipment, power, and time for this. As a result, the manufacturing process of the relevant CRT can be more streamlined and the cost can be greatly reduced. All.
