본 고안은 전자총용 스템봉착 지그에 관한 것으로서, 보다 상세하게는 벌브의 네크부 길이를 최소화하여 원가절감을 이룩할 수 있는 전자총용스템봉착 지그에 관한 것이다.The present invention relates to a stem sealing jig for an electron gun, and more particularly, to a stem sealing jig for an electron gun which can achieve cost reduction by minimizing the neck length of the bulb.

음극선관은 내면에 형광면이 형성됨과 아울러 섀도우마스크가 설치되는 패널, 전자총으로 부터 발사되는 전자비임을 편향시키는 편향요크가 외측에 장착되는 펀넬, 상기한 전자총이 위치되는 네크로 크게 구성되어 있다.The cathode ray tube has a fluorescent surface formed on the inner surface, a panel on which a shadow mask is installed, a funnel on which a deflection yoke for deflecting an electron beam emitted from an electron gun is mounted on the outside, and a neck on which the electron gun is located.

이러한 음극선관은 패널과 펀넬의 제작공정, 마스크공정 및 용접공정, 패널내면의 블랙매트릭스막 몇 형광막형성공정, AL막 증작공정, 형광막소성공정, 패널 및 펀넬의 봉착공정, 전자총의 봉입공정, 배기공정, 에이징공정등으로 제조된다.These cathode ray tubes are manufactured by manufacturing panels and funnels, masking and welding processes, forming a few fluorescence films on the inner surface of the panel, forming an AL film, firing a fluorescent film, sealing panels and funnels, and encapsulating electron guns. , Exhaust process, aging process, etc.

상기한 공정중에서 전자총을 봉일할때는 별도의 봉입기를 사용하여 벌브의 네크부에 전자총을 봉입한 다음,스템을 네트부에 열융착시킨 후 배기를 실시하게 되는데, 전자총에는 음극선관 내부에 지지설치되여 애노드전압을 인가하기 위한 복수개의 지지 스프링이 외측으로 확개되어 부착되어 있는가 하면, 게터 물질이 저장된 게터 홀더판이 외측으로 탄발 설치되어 있기 때문에 전자총을 봉입하기 위해서는 네크부의 종단을 확개하여 봉입시 제한을 받지 않도록 하고 있다.When the electron gun is sealed in the above process, the electron gun is enclosed in the neck of the bulb using a separate encapsulator, and then the stem is thermally fused to the net and exhausted. The electron gun is supported inside the cathode ray tube and is mounted on the anode. A plurality of support springs for applying a voltage are extended and attached to the outside, and the getter holder plate in which the getter material is stored is shot outwardly, so that the end of the neck is expanded to enclose the electron gun so that it is not restricted. Doing.

따라서 벌브의 네크부 길이가 필요 이상으로 길어지게 됨에 기인하여 스템융착 후 절단되어 버려지는 네크부가 제조원가를 상승시키는 한 요인으로 작용하는 문제점이 있다.Therefore, the length of the neck portion of the bulb is longer than necessary, and there is a problem in that the neck portion cut after the stem fusion acts as a factor to increase the manufacturing cost.

본 고안은 상기한 바와 같은 종래 기술의 문제점을 해소하기 위하여 안출된 것으로서, 본 고안의 목적은 스템융착 후 버려지는 네크부의 길이를 최소화 할 수 있는 전자총용 스템봉착 지그를 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide a stem sealing jig for an electron gun that can minimize the length of the neck portion discarded after stem fusion.

이를 실현하기 위하여 본 고안은 전자총 봉입기의 가이드 축에 슬라이드 가능하게 삽입되는 볼부시를 지지대의 양측단에 설치함과 아울러 이 지지대의 중앙부에 전자총 봉입구를 설치하여 이루어지는 전자총용 스템봉착지그를 제공한다,In order to realize this, the present invention provides a stem mounting jig for an electron gun formed by installing a ball bush slidably inserted into a guide shaft of an electron gun encapsulator at both ends of the support, and an electron gun enclosing hole in the center of the support. do,

상기한 전자총 봉입구는 상하단이 확개 형성됨을 특징으로 한다.The electron gun enclosing opening is characterized in that the upper and lower ends are expanded.

이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

제1도는 본 고안의 스템봉작 지그의 사시도로서, 부호(1)은 전자총 봉입기의 가이드 축을 자칭한다.1 is a perspective view of a stem sewing jig according to the present invention, and reference numeral 1 denotes a guide shaft of an electron gun encapsulation machine.

본 고안의 지그는 상기한 가이드 축(1)을 따라 별도의 승강기구(도시생략)에 의해 승강하도록 되어 있다.상기한 가이드 축(1)에 슬라이드 가능하게 삽입되는 볼부시(2)가 지지대(3)의 소정위치에 고정 설치되어 있으며, 지치대(3)의 중앙에는 전자총 봉입구(4)가 설치되어 있다.The jig of the present invention is lifted up and down by a separate lifting mechanism (not shown) along the guide shaft 1 described above. A ball bush 2 slidably inserted into the guide shaft 1 includes a support ( It is fixed at the predetermined position of 3), and the electron gun enclosing hole 4 is provided in the center of the support stand 3.

상기한 전자총 봉입구(4)는 상하단부가 벌어져 확개부(5)(6)를 형성하고 있으며, 그 내측에는 벌브의 네크부 끝단이 지지되는 턱부(7)가 형성되어 있다.The upper and lower ends of the electron gun enclosing hole 4 are opened to form the extension parts 5 and 6, and a jaw portion 7 in which the neck end of the bulb is supported is formed inside.

이와 같이 구성되는 본 고안의 지그는 전자총 봉입기의 가이드 축(1)에 지지대(3)의 볼부시(2)가 삽입된 상태에서 음극선관을 장착대(T)에 장착시킨 다음, 별도의 승강기구를 동작시켜 전자총봉입구(4)가 음극선관의 네크부와 접촉되는 상태가 되도록 한다.The jig according to the present invention configured as described above mounts the cathode ray tube to the mounting table T in a state where the ball bush 2 of the support 3 is inserted into the guide shaft 1 of the electron gun encapsulation machine, and then a separate elevator The sphere is operated to bring the electron gun enclosing hole 4 into contact with the neck portion of the cathode ray tube.

이때 전자총 봉입구(4)의 턱부(7)에 제3도에 도시한 바와 같이 음극선관의 네크부 끝단부(S)가 닿도록 한다.이와 같이 지그의 상승이 완료되면 전자총 마운팅 로도(R)를 상승시켜 전자총(E)을 상승시킨다.At this time, the neck end S of the cathode ray tube is brought into contact with the jaw portion 7 of the electron gun insertion hole 4 as shown in FIG. 3. When the ascending of the jig is completed, the electron gun mounting rod R To increase the electron gun (E).

이러한 과정에서 지지 스프링(C)은 전자총 봉입구(4)의 확개부(6)내면을 따라서 서서히 좁혀지는 상태로 상승하게 되므로 원활한 삽입을 기대할 수 있다.In this process, the support spring (C) is raised in a state that is gradually narrowed along the inner surface of the expansion portion 6 of the electron gun insertion opening (4) can be expected smooth insertion.

제4도는 상기한 일련의 동작으로 전자총 마운트가 완전히 삽입된 상태를 나타내는 도면으로서, 이 상태에서 토오치(K)로 음극선관의 네크부와 전자총의 스템부의를 가열하여 융착 시킨다.4 is a view showing a state in which the electron gun mount is completely inserted in the above-described series of operations, in which the torch K heats and fuses the neck portion of the cathode ray tube and the stem portion of the electron gun.

스템을 융착하는 작업은 종래와 동일하게 행하여지는 것으로서, 상세한 설명은 생략한다.The operation of fusing the stem is performed in the same manner as in the prior art, and detailed description thereof will be omitted.

스템의 융착이 완료된 상태에서 전자총 봉입구(4)를 상승 유지시켜주는 승강기구의 자세를 반전시키게 되면 전자총 봉입구(4)로 위로 받쳐주는 힘이 소멸하게 되므로 전자총 봉입구(4)는 자중에 의해 가이드축(1)을 타게 내리오게 된다.When the posture of the lift mechanism that maintains the gun gun opening 4 in the state of fusion of the stem is completed, the force supported by the gun gun opening 4 disappears, so the gun gun opening 4 is caused by its own weight. The guide shaft 1 is lowered.

이와 같이 행해지는 스템융착 공정은 전자총 봉입구(4)가 음극선관의 네트부와 융착이 이루어지지 않고 전자총 봉입시 안내기능을 하게 되므로 음극선관의 네크부 길이를 봉착에만 필요한 길이로 할 수 있다.In the stem fusion process performed as described above, since the electron gun encapsulation opening 4 does not fusion with the net portion of the cathode ray tube and serves as a guide function when enclosing the electron gun, the length of the neck portion of the cathode ray tube can be made as a length necessary only for sealing.

따라서 스템봉착시 절단되는 손실을 감소시킬 수 있는 이점이 있다.Therefore, there is an advantage that can reduce the cutting loss when sealing the stem.

이상 설명한 바와 같이 전자총 봉입을 위한 별도의 지그를 사용함으로서, 종래 음극선관의 네크부 종단을 길게하여 전자총 안내기능 갖게 하는데에 따른 제반 문제점을 해소 할 수 있다.As described above, by using a separate jig for encapsulating the electron gun, it is possible to solve the problems associated with having the electron gun guide function by lengthening the neck end of the conventional cathode ray tube.
