본 고안은 음극선관의 넥크부 봉지 장치에 관한 것으로서, 보다 상세하게는 음극선관의 넥크부 봉지 길이가 스템핀의 길이보다 짧게 형성되도록 하는 음극선관의 넥크부 봉지 장치에 관한 것이다.The present invention relates to a neck portion encapsulation device of a cathode ray tube, and more particularly, to a neck portion encapsulation device of a cathode ray tube such that the neck portion encapsulation length of the cathode ray tube is shorter than the length of the stem pin.
일반적으로 음극선관은 안쪽에 섀도우 마스크가 지지 설치되어지는 패널부와, 편향요크가 외주에 설치되어지는 퍼늘부와, 전자총이 설치되어지는 넥크부로 이루어져 있다.Generally, a cathode ray tube consists of a panel part in which a shadow mask is supported inside, a perch part in which a deflection yoke is provided on the outer periphery, and a neck part in which an electron gun is installed.
이러한 음극선관은 패널과 펀넬의 제작공정, 마스크가 공및 용접공정, 패널내면의 블랙 매트릭스막 및 형광막 형성공정, 알루미튬막 증착공정, 형광막 소성공정, 패널 및 펀넬의 봉착공정, 전자총의 봉입공정, 배기공정, 에이징 공정 등으로 순차 진행되어 제작완료 된다.These cathode ray tubes are used for manufacturing panels and funnels, masking and welding processes, forming black matrix and fluorescent films on the inner surface of panels, aluminium film deposition processes, fluorescent film firing processes, panel and funnel sealing processes, and electron gun encapsulation. The process is completed by the process, the exhaust process, and the aging process.
이와 같이 음극선관의 조립이 이루어지면, 음극선관 내를 진공상태로 하기 위하여, 음극선관 내의 공기를 뽑아내게 되는데, 이를 위하여 음극선관의 넥크부에는 공기를 뽑아 내기위한 배기관이 연장 형성되어 있다.When the cathode ray tube is assembled in this way, in order to vacuum the inside of the cathode ray tube, air is drawn out of the cathode ray tube. To this end, an exhaust pipe for extracting air is formed in the neck portion of the cathode ray tube.
이러한 배기관은 음극 선관 내의 공기를 뽑아 내어 음극선관이 진공 상태로 되면 절단함과 동시에 봉지 시키게 되는데, 제2도에배개관이 절단되어 봉지된 상태의 넥크부가 도시되어 있다.The exhaust pipe is drawn out of the air in the cathode ray tube to be cut at the same time and sealed when the cathode ray tube is in a vacuum state, the neck portion of the exhaust pipe is cut and sealed in Figure 2 is shown.
즉, 넥크부(A)의 후단에는 전자총의 각 전극에 전압을 인가하기 위한 스템핀(B)가 다수개 돌출 형성되어 있으며, 이들 스템핀(B)가 다수개 돌출 형성되어 있으며, 이들 스템핀(B)의 중앙에는 배기관이 잘려져 봉지된 봉지부(C)가 스펨핀(B)의 길이보다 길게 형성되어 있다.That is, at the rear end of the neck portion A, a plurality of stem pins B are formed to protrude from each electrode of the electron gun, and a plurality of stem pins B are formed to protrude. In the center of (B), the exhaust pipe is cut off, and the encapsulation portion (C) sealed is formed longer than the length of the spempin (B).
제3도는 종래의 음극선관의 넥크부 봉지 장치의 단면도로서, 베이스판(D)의 윗면에는 넥크부(A)가 삽입되는 홈(E)가 형서되어 있으며, 이 홈(E)의 아래측으로는 히이터(F)가 주위에 설치된 구멍(G)가 뚫려져 있는 구성으로 되어 있다.3 is a cross-sectional view of a neck portion sealing device of a conventional cathode ray tube, in which a groove E into which the neck portion A is inserted is formed on the upper surface of the base plate D. The heater G has a structure in which the hole G provided around it is drilled.
이와 같이 구성되는 넥크부 봉지 장치는 홈(E)에 음극선관의 넥크부(A)를 삽입시키게 되면 홈(E)의 바닥면에 스템핀(B)가 지지되고, 배기관이 구멍(G)를 관통하는 상태를 놓여지게 된다.When the neck portion sealing device configured as described above inserts the neck portion A of the cathode ray tube into the groove E, the stem pin B is supported on the bottom surface of the groove E, and the exhaust pipe opens the hole G. The penetrating state is placed.
이 상태에서 히터(F)에 전원을 인가하면 히터(F)의 아래측 끝단부에서 2/3되는 지점에 위치된 배기관이 용융되어 절단되면서 봉지 된다.When power is applied to the heater F in this state, the exhaust pipe located at a point 2/3 at the lower end of the heater F is melted and cut and sealed.
따라서 배기관은 스템핀(B)의 끝단부 보다 아래부 위가 절단되어 제2도에 도시한 바와 같이 봉지부(C)는 스템핀(B)보다 길게 된다.Therefore, the exhaust pipe is cut below the end of the stem pin (B) so that the sealing portion (C) is longer than the stem pin (B) as shown in FIG.
이와 같이 봉지부(C)가 스템핀(B)보다 길게 형성되면 다음 공정에서 작업을 할 때 이 봉지부(C)가 작업자의 부주의에 의해 파손되는 문제점이 있으며, 음극선관을 반제품 상태로 수출하는 경우에는 포장시나 운반시에 봉지부(C)가 주변물체에 부딪쳐 파손되어 버리는 문제점이 있다.If the sealing portion (C) is formed longer than the stem pin (B) in this way there is a problem that the sealing portion (C) is damaged by carelessness of the operator when working in the next process, and export the cathode ray tube in semi-finished state In this case, there is a problem that the encapsulation part C hits the surrounding object and breaks during packaging or transportation.
본 고안은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은 음극선관의 넥크부 봉지 길이가 스템핀의 길이보다 짧게 형성되도록 하는 음극선곤의 넥크부 봉지 장치를 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 neck portion sealing device of the cathode line so that the length of the neck portion of the cathode ray tube shorter than the length of the stem pin. It is.
상기한 바와 같은 목적을 달성하기 위하여 본 고안은 윗쪽부에 뚫려진 배기관 삽입 구멍과 연통되어 히이터의 상단부측이 위치되는 홈이 뚫려짐과 아울러 다수개의 스테핀 삽입구멍이 뚫려진 커바오, 아래쪽부에 뚫려진 배기관 관통 구멍과 연통되어 히이터 하단 부측이 위치되는 홈이 뚫려진 베이스판으로 구성된 음극선관의 넥크부 봉지 장치를 제공한다.In order to achieve the above object, the present invention communicates with an exhaust pipe insertion hole drilled in the upper part, and a groove in which the upper end side of the heater is located is drilled, and a plurality of stepper insertion holes are drilled, the lower part. Provided is a neck portion sealing device of a cathode ray tube composed of a grooved base plate communicating with an exhaust pipe through hole drilled in the groove and having a heater lower side.
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 음극선관의 넥크부 봉지 장치의 측단면도로서, 부호(1)은 베이스판을 나타낸다.1 is a side cross-sectional view of a neck portion sealing device of a cathode ray tube according to the present invention, and reference numeral 1 denotes a base plate.
베이스판(1)의 중앙부 위쪽에는 홈(2)가 형성되어 히이터(3)이 하단부측이 위치되어 있으며, 홈(2)는 베이스판(1)의 아래쪽에 뚫려진 배기관 관통구멍(4)와 연통되어 있다.A groove 2 is formed above the central portion of the base plate 1 so that the heater 3 is located at the lower end side thereof, and the groove 2 has an exhaust pipe through hole 4 drilled under the base plate 1. In communication.
상기한 베이스핀(1)의 윗쪽면에는 커버(5)가 체결수단에 의해 일체로 결합되어 있다.The cover 5 is integrally coupled to the upper surface of the base pin 1 by a fastening means.
커버(5)의 중앙부 위쪽에는 넥크부(A)의 후단면이 안치되는 시이트(6)이 형성되어 있으며, 이 시이트(6)에는 스템핀 삽입 구멍(7)이 뚫려져 커버(5)의 아래면까지 연장 형성되어 있다.A sheet 6 having a rear end surface of the neck portion A is formed above the central portion of the cover 5, and a stem pin insertion hole 7 is drilled in the sheet 6 to form a lower portion of the cover 5. It extends to the surface.
그리고 커버(5)의 배기관 삽입 구멍(8)의 아래측으로는 홈(9)가 연장 형성되어 히이터(3)의 상단부측이 위치되어 있다.A groove 9 extends below the exhaust pipe insertion hole 8 of the cover 5, and the upper end side of the heater 3 is located.
이와 같이 구성되는 본 고안은 제1도에 도시한 바와 같이, 스펨핀 삽입 구멍(7)에 넥크부(A)로 부터돌출형성된 스템핀(B)를 삽입시키고, 넥크부(A)의 후단면을 시이트(6)에 안치 시키면, 배기관은 커버(5)의 홈(9)와 베이스판(1)의 홈(2)를 경유하여 배기관 관통 구멍(4)를 관통하는 상태로 위치된다.The present invention configured as described above, as shown in FIG. 1, inserts the stem pin (B) protruding from the neck portion (A) into the spempin insertion hole (7), the rear end surface of the neck portion (A) Is placed in the sheet 6, the exhaust pipe is positioned in the state of passing through the exhaust pipe through-hole 4 via the groove 9 of the cover 5 and the groove 2 of the base plate 1.
이러한 상태에서 히이터(3)에 전압을 인가시켜 통상의 봉지 방법으로 배기관을 봉지시키게 되면, 히이터(3)의 아래쪽으로 부터 2/3되는 지점이 용융되어 절단 되면서 봉지 된다.When the exhaust pipe is sealed by the normal sealing method by applying a voltage to the heater 3 in such a state, the point 2/3 from the bottom of the heater 3 is melted and cut and sealed.
따라서 봉지부의 길이는 스펨핀(B)보다 작게 된다.Therefore, the length of the encapsulation portion is smaller than the spempin (B).
이상 설명한 바와 같이 본 고안은 넥크부 봉지 장치로 배기관을 봉지하게 되면 봉지부의 길이가 스펨핀 보다 작게 형성됨으로써, 다음 공정에서 작업할때나 반제품 상태로 운반 및 포장을 할때 봉지부가 주변물체와 부딪치지 않게 되어 파손을 방지할 수 있다.As described above, the present invention encapsulates the exhaust pipe with the neck part encapsulation device so that the length of the encapsulation part is smaller than that of the spempin, so that the encapsulation part does not collide with the surrounding object when working in the next process or carrying and packaging the semifinished product. To prevent damage.
