AUTOMATED OPTICAL INSPECTION INSTRUMENT EQUIPPED WITH ADJUSTABLE COMBINATION OF IMAGE ACQUISITION, AND ADJUSTMENT METHOD FOR COMBINATION OF IMAGE ACQUISITION

摘要

To provide an automated optical inspection (AOI) instrument that is equipped with an adjustable combination of an image acquisition, and to provide an adjustment method for combination of the image acquisition.SOLUTION: An automated optical inspection instrument includes: at least one image acquisition device; at least one movable light source; and a movement mechanism of a device under test (DUT). A control circuit is configured to move the DUT; select the one light source; and control the light source to move or rotate the light source. The control circuit is capable of implementing an acquisition action by sequentially replacing a plurality of combinations of image acquisition. Respective combinations of the image acquisition are configured to record the image acquisition device, a position and angle of the DUT, the light source and a position and angle of the light source with respect to the DUT. A position or angle of the acquisition combination is different. Accordingly, many image acquisition results can be quickly and automatically acquired with respect to the DUT.SELECTED DRAWING: Figure 2
