Amount puies forward efficient purpose again.
Optic test method is increasingly taken seriously in recent years.Automatic visual inspection system (Automatic Optical
Inspection System, abbreviation AOpeitao) core be a set of CCD camera systems, AC Servo Control workbench and figure
As processing system.When being detected, the printed circuit board (PCB) for needing to detect is placed on the workbench of AOI system first, passed through
Positioning, recalls the detection program for needing to detect product, and wiring board is sent to below camera lens by workbench, and camera lens captures wiring board
After image, processor will be when workbench moves to next position to the image analysis processing captured, by entering to image
Row continuous processing, obtains higher detection speed.And in order to realize detection, it is necessary to it is matched with device on line detection circuit plate and leaks
Insert, insert inclined camera system, basic preparation is carried out for detection.
But according to the measurement request of circuit board, in addition it is also necessary to inspection survey is carried out to its face character, direction polarity, spacing etc.
Amount.
