Abstract

본 발명은 브라운관의 배기 공정중에 진공도 변화를 알아보기 위한 브라운관의 진공도 측정장치에 관한 것으로, 전자총을 봉입한 튜브를 싣고서 배기로를 통과하기 위한 통상의 돌리의 흡입관에 연결되어 진공상태를 감지하고 신호화하는 진공도 감지 수단과, 상기 진공도 감지 수단에서 출력되는 신호를 인가받아 해당되는 진공도를 표시하기 위한 계측 수단을 포함 구성하여 배기 공정하에서 브라운관의 진공도를 측정할 수 있도록 한 것을 특징으로 하는 브라운관의 진공도 측정장치를 제공하여 종래의 배기공정상 배기펌프의 효율 대 동작시간의 비를 데이터로 하여 배기공정을 제어 동작하므로서, 튜프(Tube)내의 진공도가 일정하게 유지될 수 있도록 제어하기가 어려운 문제점이 발생하여 생산되는 모든 튜프(Tube)의 수명이 달라지는 문제점을 해소하는 효과가 있다.The present invention relates to a vacuum tube vacuum measuring device for checking the vacuum degree change during the exhaust tube exhaust process, and is connected to the suction tube of a conventional dolly for passing through the exhaust path by loading the tube filled with the electron gun, A vacuum degree detecting means for signaling and a measuring means for displaying a corresponding vacuum degree by receiving a signal output from the vacuum degree detecting means, so that the vacuum degree of the CRT can be measured under an exhaust process. It is difficult to control so that the vacuum degree in the tube can be kept constant by controlling the evacuation process by providing the vacuum degree measuring device and controlling the evacuation process using the ratio of the efficiency of the exhaust pump to the operating time in the conventional exhaust process as data. Solve the problem that the lifespan of all the tubes produced This has the effect of.
