본 고안은 음극선관에 사용되는 전자총의 캐소드조립체에 있어서 인너슬리브(inner sleeve)의 구조개선에 관한 것으로, 특히 인너슬리브에 대한 간단한 구조개선을 통해 이 인너슬리브와 캐소드캡간의 조립이 보다 원활, 정확하게 되도록 하여 그 조립불량을 크게 줄일 수 있도록 안출한 것이다.The present invention relates to the structural improvement of the inner sleeve in the cathode assembly of the electron gun used in the cathode ray tube. Especially, the assembly between the inner sleeve and the cathode cap is more smoothly and accurately through the simple structural improvement of the inner sleeve. It is designed to greatly reduce the assembly defects.

음극선관용 전자총의 캐소드조립체를 구성함에 있어서는 파우더상의 전극 구성물이 부착지지되는 캐소드캡과, 이 캐소드캡을 단부에 설치지지하고 내부에는 상기 캐소드캡을 가열하여 캡상의 전극구성물로부터 전자비임이 방출되도록하기 위한 열선이 내장되는 인너슬리브간을 조립용접해주는 과정이 필요하게 되는데, 현재 이러한 캐소드캡 및 인너슬리브간의 조립용접과정을 포함한 전자총의 조립완성은 전자총을 구성하는 각 부품의 이송공급장치 및 용접장치등을 포함하는 일련의 자동화된 조립라인을 통해 수행되고 있다.In the cathode assembly of the cathode ray tube electron gun, the cathode cap to which the powdery electrode component is attached and supported, and the cathode cap is installed at the end and the cathode cap is heated therein to emit the electron beam from the electrode component of the cap. The process of assembling and welding between inner sleeves with built-in heating wires is required. At present, the assembly of the electron gun including the assembly welding process between the cathode cap and the inner sleeve is completed. It is carried out through a series of automated assembly lines including.

종래의 인너슬리브(1')는 제1도에서 보는 바와 같이 슬리브(1') 전체가 단순원통체로 되어 있었기 때문에 통상의 전자총조립라인상에 있어서 정해진 두 위치 사이에서 원호운동하는 캐소드캡이송아암(5)이 그 단부에 공급파지된 한 캐소드캡(2)을 일정위치에 공급정지되어 있는 한 인너슬리브(1')상단에 정확히 안착조립시킬 수 있도록하려면 그와 관련한 장치들의 기구적구성 및 운동매카니즘이 고도로 정밀하게 이루어져야 할 것이 요구되는데, 실제 현장에서는 관련기구들의 마모나 요철형성, 주변진도, 운동부유격등과 같은 여러 가지 요인에 의해 상기 인너슬리브(1')에 대한 캐소드캡(2)의 조립위치가 조금씩 어긋나게되는 일이 빈번히 발생하여 목적한 바의 조립이 이루어지지 않거나 불량조립된 제품이 다발하고 있는 실정이다.In the conventional inner sleeve 1 ', as shown in FIG. 1, since the entire sleeve 1' is a simple cylinder, a cathode cap transfer arm that arcs between two predetermined positions on a conventional electron gun assembly line ( 5) In order to be able to accurately seat and attach the cathode cap 2 supplied at its end to the inner sleeve 1 'as long as the supply cap is stopped at a certain position, the mechanical configuration and the movement mechanism of the related devices This highly precise requirement is required. In practice, the assembly of the cathode cap 2 to the inner sleeve 1 'may be caused by various factors such as wear, irregularities, periphery, and movement of the related equipment. As the position is shifted little by little, the assembly of the intended bar is not made or the defective assembly is bundled.

본 고안은 이러한 종래의 문제점을 매우 효과적으로 해소할 수 있도록 안출된 새롭고 유용한 인너슬리브구조인 것으로, 그 구체적인 기술내용과 작용효과를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is a new and useful inner sleeve structure devised to solve such a conventional problem very effectively, the specific technical details and effects will be described in detail based on the accompanying drawings.

즉, 본 고안은 제2도에서 보는 바와 같이 통상적인 전자총 캐소드조립체의 인너슬리브(1)를 구성함에 있어서, 캐소드캡(2)이 삽착조립되는 상기 인너슬리브(1)의 일측 단부에 끝부분으로 갈수록 점차 직경이 작아지는 원추상부(1a)를 형성하여서 된 것이다.That is, the present invention, in the inner sleeve 1 of the conventional electron gun cathode assembly, as shown in Figure 2, the cathode cap 2 is inserted into the end portion at one end of the inner sleeve (1) The conical part 1a which becomes small gradually in diameter is formed.

상기 원추상부(1a)를 형성하는 바람직한 실시예로서는 제3도에서 보는 바와 같이 전술한 캐소드캡(2)과의 조립을 위해 일정위치상의 심봉(3)에 공급삽지된 인너슬리브(1)의 단부를 캐소드캡(2)이 조립되기전 원추상요부(4a)를 가진 공구(4)로 압박하여 목적하는 바의 원추상부(1a)를 포밍토록 할 수 있다. 여기에서 상기 공구(4)는 전자총조립라인상의 관련기구들, 예컨대 캐소드캡이송 아암(5)등의 작용과 관련하여 적시에 왕복운동하면서 그 원추상 요부(4a)로 상기 인너슬리브(1)의 단부에 원추상부(1a)를 적시에 자동형성해주도록 설치할 수 있다.As a preferred embodiment of forming the conical portion 1a, as shown in FIG. 3, the end of the inner sleeve 1 supplied and inserted into the mandrel 3 at a predetermined position for assembly with the cathode cap 2 described above is used. Before the cathode cap 2 is assembled, it can be pressed with the tool 4 having the conical recesses 4a to form the conical portions 1a of the desired bar. The tool 4 here is adapted to move the inner sleeve 1 into its conical recess 4a while reciprocating in a timely manner with respect to the action of the associated mechanisms on the electron gun assembly line, such as the cathode cap feed arm 5 and the like. The conical portion 1a may be installed at the end to automatically timely form.

이와 같이 된 본 고안의 인너슬리브(1)는 캐소드캡(2)이 이동조립되는 그 단부에 끝부분쪽으로 갈수록 폭이 좁아지는 원추상부(1a)를 가지기 때문에 아암( 5)에 의해 이 원추상부(1a)쪽으로 이동된 캐소드캡(2) 연부가 원추상부(1a)의 어느 부위로부터 접촉조립되더라도 상기 원추상부(1a)사 캐소드캡(2)을 인너슬리브 (1) 본체상의 소망되는 위치로 원활하게 안내해주게 됨으로써 항시 목적하는 바의 조립상태로 정확, 원활하게 조립되는 뛰어난 효과를 제공한다.Since the inner sleeve 1 of the present invention has a conical portion 1a, the width of which is narrowed toward the end portion at the end portion of the cathode cap 2 that is moved and assembled, this conical portion ( Even if the cathode cap 2 moved toward 1a is assembled by contact from any part of the conical portion 1a, the conical portion 1a's cathode cap 2 is smoothly moved to a desired position on the inner sleeve 1 body. By guiding, it provides an excellent effect of assembling accurately and smoothly at the desired state of assembly.

따라서 본 고안은 간단하면서도 매우 효과적인 구조개선을 통해 전자총부품의 조립불량을 현저히 줄여 제품의 품질향상 및 생산성향상에 크게 기여 할 수 있게 된 신규유용한 고안인 것이다.Therefore, the present invention is a novel and useful design that can significantly contribute to the improvement of product quality and productivity by significantly reducing assembly defects of electronic gun parts through simple and very effective structural improvement.
