배터리의 경우 스티커의 이상 유무, 인쇄유무, (+),(-) 기호의 음각인쇄 여부, 캡의 유무 등을 검사하게 되는데, 본 발명에 의하면 전면감시카메라(7)와 배면감시카메라(8) 그리고 2대의 상면감시카메라(9)에서 이들을 동시에 스캔하여 도 3과 같이 영상으로 검사자에게 출력함과 동시에 컴퓨터(4)에서 검사 소프트웨어를 통해서 제품(A)의 상태를 판단하게 감사자에게 시청각적으로 고지하게 되는 것이다.In the case of the battery, whether the sticker is abnormal, printing, whether the negative (+), (-) sign engraved, whether there is a cap or the like, according to the present invention, the front surveillance camera (7) and rear surveillance camera (8) In addition, the two top surveillance cameras 9 simultaneously scan them and output them to the inspector as an image as shown in FIG. 3, and at the same time, the auditor visually determines the state of the product A through the inspection software in the computer 4. It will be announced.

도 4는 본 발명에서 제공하는 머신비전 검사기의 시스템 구조도를 도시한 것이다.4 is a diagram illustrating a system structure of the machine vision inspector provided in the present invention.

도시된 바에 의하면 머신비전 검사기(1)에 장착된 감지센서(10)를 통해서 검사 제품(A)의 입력이 확인되면 PLC(11)에서 이송컨베이어(6)로 이송정지 신호를 보낸다.As shown, when the input of the inspection product A is confirmed through the sensor 10 mounted on the machine vision inspector 1, the PLC 11 sends a transport stop signal to the transport conveyor 6.

이때, IO-인터페이스(interface)를 통해서 PLC(11)는 컴퓨터(4)에 검사시작신호(Start)신호를 전송한다.At this time, the PLC 11 transmits a test start signal (Start) signal to the computer 4 via the IO-interface.

컴퓨터(4)의 검사 소프트웨어는 1394 인터페이스(interface)를 통해서 전면 및 배면감시카메라(7)(8)와 상면감시카메라(9)에 영상획득을 위한 촬영신호를 보내서 영상을 획득한다.The inspection software of the computer 4 acquires an image by sending a capture signal for image acquisition to the front and rear surveillance cameras 7 and 8 and the top surveillance camera 9 via a 1394 interface.

획득된 영상은 컴퓨터(4)의 검사 소프트웨어에서 분석해서 OK 혹은 NG 신호를 PLC로 다시 보내며, OK의 경우 다음 제품을 지속적으로 검사하게 되지만, NG의 경우에는 도시되지는 않았지만 PLC(11)의 장비 구동부에서 제품을 다른 곳으로 이송시킨다.The acquired image is analyzed by the inspection software of the computer 4 and sends an OK or NG signal back to the PLC, and in the case of OK, the next product is continuously inspected, but in the case of NG, the equipment of the PLC 11 is not shown. Drive the product to another place.
