Abstract

본 발명은 칼라 음극선관의 봉지각도 자동측정 및 조정방법에 관한 것이다. 봉지각도 측정 및 조정방법에 있어서 종래에는, 마운트에 있는 구멍을 통과할 상을 스크린에 맺히게 한 후 CCD카메라를 통해 모니터에 출력시켜 작업자가 모니터에 출력된 상의 크기를 보면서 작업을 수행하였었다. 때문에 모니터에 출력된 상의 크기가 최대라고 판단하는 것은 어떤 일정한 기준값이 없이 순전히 작업자의 주관적인 판단에 의하는 것이므로 각 작업자의 시력차이 및 숙련도, 그리고 그 날의 컨디션에 따라 변화 여지가 매우 많아 오판으로 인한 불량의 원인이 되고 있으며, 작업을 행하는데 있어 시간이 많이 걸린다는 문제점 등이 있었다.The present invention relates to a method for automatically measuring and adjusting the sealing angle of a color cathode ray tube. In the method of measuring and adjusting the sealing angle, conventionally, the image to pass through the hole in the mount is formed on the screen, and then outputted to the monitor through a CCD camera, and the operator performed the operation while looking at the size of the image output on the monitor. Therefore, judging that the size of the image displayed on the monitor is the maximum is based on the subjective judgment of the worker without any constant reference value, so there is a lot of room for change depending on the eyesight difference and skill of each worker and the condition of the day. There have been problems such as the cause of the defects and the time required to perform the work.

본 발명은 상기와 같은 종래의 문제점들을 개선 및 해소시키기 위하여 창안한 것으로 CCD카메라와 모니터 사이에 이미지 프로세서를 사용하여 연상처리를 수행함으로써, 종래 작업자의 육안 판정에 따르던 측정을 수치화시켜 스크린에 맺힌 상과 함께 모니터에 출력시킴으로써 이중의 판단자료를 제공하고, 더 나아가 이 수치화된 영상의 데이타를 스테핑모터의 구동 제어회로에 연결하여 자동적으로 봉지각도를 맞출 수 있게한 봉지각도 자동측정 및 조정방법에 관한 것이다.The present invention has been devised to improve and solve the above-mentioned problems. By performing an associative process using an image processor between a CCD camera and a monitor, an image formed on a screen by digitizing a measurement according to the naked eye of a conventional operator is digitized. And the method for automatic measurement and adjustment of the encapsulation angle, which provides double judgment data by outputting the result to the monitor, and automatically connects the digitized image data to the stepping motor driving control circuit to automatically adjust the encapsulation angle. will be.
