1. automatic optical detecting system is formed with the detected object of flexible printed-circuit board unit continuously above being used to detect, this automatic optical detecting system comprises:

  • Be used to provide the loading bin of detected object;

    The primary vision detection components is used to detect the surface of the detected object that loading bin provides;

    AndBe used to unload the emptier of detected object to be detected,Wherein, said primary vision detection components comprises a plurality of image pick-uping parts that the surface of said detected object is taken,Each said image pick-uping part comprises video camera, makes said automatic optical detecting system comprise first video camera, second video camera and the 3rd video camera at least,Wherein, first video camera is used to take the internal lead district, so that detect bending, stain, cut and the foreign matter of the internal lead of said flexible printed-circuit board unit;

    Second video camera;

    Be used to take the pattern coating region and the solder resist district of said flexible printed-circuit board unit;

    So that the pin hole in the cosmetic issue of check pattern coating region, solder resist district and cut position deviation, the cosmetic issue of said pattern coating region are stain, cut and foreign matter;

    AndThe 3rd video camera is used to take the width of said detected object, so that detect pin hole, the cut position in the solder resist district of said flexible printed-circuit board unit and depart from and carry breaking of datum hole,These image pick-uping parts have the different visual scope, correspond respectively to the test item of said detected object.
