The working principle of the utility model are as follows: AOI automated optical inspection main function is to search each of PCB instead of artificial
Kind open defect scans backlight by optical method, when backlight is lit on AOI automated optical inspection station
When, by the motor driven screw rod beaten on lamp device, height adjustment is carried out to the three-basic-colour lamp being mounted on the first mounting rack, and
By manual rotation's three-basic-colour lamp, angular adjustment is carried out to three-basic-colour lamp by adjusting knob, at this point, the light source of three-basic-colour lamp by
45 ° are irradiated backlight plate surface, and by manually carrying out colour switching to three-basic-colour lamp, since three-basic-colour lamp can carry out three
The colour switching each time of secondary colour switching (red, green, blue) and three-basic-colour lamp shoots image to backlight by CCD camera, leads to
Cross logical algorithm and compared with the image shot three times, to be detected to backlight plate surface, discover whether there are white point,
Scratch defects, if unchanged after the image contrast shot three times, backlight detection is qualified.
The utility model has the following beneficial effects: the utility model beats lamp device by the adjustable height of setting and angle,
And it is beaten when the three-basic-colour lamp on lamp device carries out colour switching and each colour switching by manual control and passes through CCD camera to point
Backlight after bright is shot, and judges whether backlight is qualified after comparing by the image shot three times, so not only
The case where solving due to blocking for white light and depositing the missing inspection occurred when detecting and erroneous detection, and detect precisely, further mention
The production quality of high product.
