본 고안은 칼라 브라운관 제조에 관한 것으로, 특히 전자총(electron gun) 중간 조립체(sub assembly)의 정합(alignment)상태를 검사하는데 사용되는 신규한 구성의 지그(jig)에 관한 것이다.FIELD OF THE INVENTION The present invention relates to the production of color CRTs, and more particularly to a jig of a novel construction used to check the alignment of an electron gun subassembly.

전자총 어셈블리는 판재를 성형 및 용접하여 각 구성전극(4)을 제작하고 이를 비드글래스(bead glass; 2)로 융착 고정한 뒤 이에 스템(stem; 3)을 부착하는 과정을 거쳐 제1도에 도시된 바와 같은 전자총 중간조립체(1)를 형성하게 된다. 금속제 부품의 조립에 의한 공차(公差)는 그다지 크지 않으나 비드글래스(2)와 스템(3)은 유동체(流動體)인 유리이므로 이들에 의해 결합 지지되는 전자총 어셈블리의 전합은 매우 정밀하게 관리되지 않으면 정확한 화상의 형성이 어렵게 된다.The electron gun assembly is formed by forming and welding a sheet material to fabricate each component electrode 4, and then fusion-fixing it with bead glass 2 and attaching a stem 3 to it. The electron gun intermediate assembly 1 is formed. Tolerance due to the assembly of metal parts is not very large, but the bead glass 2 and the stem 3 are fluid glass, so the total of the electron gun assemblies held together by them is not managed very precisely. Accurate image formation becomes difficult.

이에 따라 유리를 사용하는 공정이 모두 완료되는 스템 부착이 완료되면 일차적으로 이 전자총 중간조립체의 정합상태를 검사하는 것이 바람직하다. 그러나 전자총 어셈블리의 정합상태 파악의 기준이 되는 것은 스템(3)과 컨버전스 컵(convergence cup)이므로 컨버전스 컵(5; 제1도에 점선으로 표시됨)의 용접전에는 이를 검사할 수 없었다.Accordingly, it is preferable to first check the mating state of the electron gun intermediate assembly when the attachment of the stem is completed. However, since the stem 3 and the convergence cup were the criteria for determining the matching state of the electron gun assembly, it could not be inspected before welding the convergence cup 5 (indicated by the dotted line in FIG. 1).

이에 따라 종래에는 정합이 불량하여 편심(mount tilt)이 발생한 전자총 중간조립체(1)에 계속적으로 리본(ribon)접속등을 행하여 가다가 컨버전스컵의 부착후에야 이를 발견하게 되므로 무익한 작업공수와 자재의 손실이 큰 문제가 있었다.Accordingly, conventionally, the ribbon is connected to the electron gun intermediate assembly 1 which has a misalignment due to misalignment, and is found only after the convergence cup is attached. There was a big problem.

본 고안은 이러한 종래의 문제를 감안하여 스템이 부착되는 즉시 전자총 중간 조립체의 정합상태를 검사할 수 있는 신규한 구성의 지그를 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a jig of a novel configuration that can check the mating state of the electron gun intermediate assembly immediately upon attachment of the stem.

이러한 목적을 달성하기 위해 본 고안에 따른 전자총 정합 검사용 지그는 컨버전스 컵과 동일한 외경을 가지는 몸체와, 이 몸체에 설치되어 각각 중간 조립체 후단 전극의 전극 구멍에 삽입되는 3개의 결합핀을 구비하는 것을 특징으로 한다.In order to achieve this purpose, the jig for electron gun matching inspection according to the present invention has a body having the same outer diameter as the convergence cup, and three coupling pins installed in the body and inserted into the electrode holes of the intermediate electrode of the intermediate assembly. It features.

이하 첨부된 도면을 참조하여 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제2도에서, 본 고안에 따른 지그(6)는 컨버전스 컵과 동일한 외경을 가지는 원통형의 몸체(7)와, 이 몸체(7)로부터 하방으로 연장되는 세 결합핀(8)을 구비한다. 결합핀(8)간의 배열은 델타(Δ)형 칼라 브라운관의 경우에는 정삼각형으로 배열되고, 인라인(in-line)형 칼라 브라운관의 경우에는 수평으로 배열된다.In FIG. 2, the jig 6 according to the present invention has a cylindrical body 7 having the same outer diameter as the convergence cup and three coupling pins 8 extending downward from the body 7. The arrangement between the coupling pins 8 is arranged in an equilateral triangle in the case of the delta (Δ) type color CRT and in a horizontal in the case of the in-line type CRT.

각 결합핀(8)간의 간격은 후단 구성전극(4)의 전극구멍(4a)간격에 대응하게 되지만, 본 고안 지그(6)를 크기가 유사한 여러 규격의 전자총 검사에 범용으로 사용하기 위해서는 양측 결합핀(8b)의 직경은 각 규격의 후단전극의 전극구멍을 겹쳐서 투영한 경우 각 전극구멍의 교차선에 내접하는 최대원의 직경으로 구성하는 것이 바람직하다. 한편, 중앙의 결합핀(8a)은 최종전극을 관통하여 충분히 연장되는 것이 바람직한 바, 양측의 결합핀(8b)에 비해 더 길게 구성된다.The spacing between the coupling pins 8 corresponds to the spacing of the electrode holes 4a of the rear end electrode 4, but in order for the jig 6 of the present invention to be used universally for inspection of electron guns of various sizes having similar sizes, both couplings are used. It is preferable that the diameter of the pin 8b is comprised by the diameter of the largest circle which inscribes in the intersection line of each electrode hole, when the electrode hole of the back electrode of each specification is projected overlapping. On the other hand, the coupling pin (8a) of the center preferably extends sufficiently through the final electrode, it is configured longer than the coupling pin (8b) on both sides.

이와 같이 구성된 본 고안 지그(6)는 전자총 중간조립체(1)의 후단 구성 전극(4)에 삽입되어 이의 정합상태를 검사하는데 사용된다.The jig 6 of the present invention configured as described above is inserted into the rear end electrode 4 of the electron gun intermediate assembly 1 and used to check its mating state.

즉, 제3도에서, 본 고안 지그(6)가 삽입된 전자총 중간조립체(1)는 스템(3)이 회전 지지부(9)상에 설치되어 검사된다.That is, in FIG. 3, the electron gun intermediate assembly 1 into which the jig 6 of the present invention is inserted is inspected with the stem 3 installed on the rotation support 9.

본 고안 지그(6)의 측면에는 기준 측정점으로서 프루브(probe; 10)가 접촉되고 이 상태에서 전자총 중간조립체(1)를 회전시켜 이 프루브(10)와의 이탈정도를 측정한다. 이러한 측정에 의해 얻어진 프루브(10) 선단으로부터 최대 이격거리와 최소 근접거리의 차이의 1/2이 이 전자총 중간 조립체(1)의 편심량이 된다.Probe 10 is contacted to the side of the jig 6 as a reference measurement point, and in this state, the electron gun intermediate assembly 1 is rotated to measure the degree of departure from the probe 10. One half of the difference between the maximum separation distance and the minimum proximity distance from the tip of the probe 10 obtained by this measurement becomes the eccentricity of the electron gun intermediate assembly 1.

이때 측정된 편심량이 소정의 허용치를 초과하게 되면 이 전자총 중간 조립체는 편심이 과도한 불량품으로 처리되고, 양품으로 검사된 전자총 중간 조립체만이 후속공정에 투입된다.At this time, if the measured eccentricity exceeds a predetermined allowance, the electron gun intermediate assembly is treated as a defective product with excessive eccentricity, and only the electron gun intermediate assembly inspected as good is put into the subsequent process.

이와 같이 본 고안에 의하면 정합불량인 전자총 중간 조립체를 조기에 검사파악하여 처리함으로써 무익한 공수 및 자재의 투입을 방지할 수 있으며, 전자총 중간 조립체 제조공정의 품질 관리가 용이해지게 된다.As such, according to the present invention, by inspecting and treating the misalignment of the electron gun intermediate assembly at an early stage, it is possible to prevent the use of unnecessary airborne and materials, and to facilitate the quality control of the electron gun intermediate assembly manufacturing process.

이에 따라 본 고안은 브라운 제조의 원가절감과 품질향상에 큰 효과를 발휘하게 된다.Accordingly, the present invention has a great effect on cost reduction and quality improvement of brown manufacturing.
