Domain is quite varied, such as detecting pcb board (i.e. printed circuit board (PCB)), because pcb board is complicated, its designed lines is more and more,
The number of plies is also more and more, therefore is used in line optics detector to detect that pcb board is ripe more than manual detection mode, efficient, so that
Advantageously in guarantee accuracy of detection, and then control product quality.
Pcb board is placed on a flat board during existing online optical detector detection, a table of pcb board is first detected
Face, then by pcb board turn-over, to detect another surface of pcb board, two surfaces of pcb board can not be thus detected simultaneously,
So as to cause its detection efficiency low；Further, since micro bending may occur for measured piece, and light source intensity of illumination not
Reach and there is the factors such as shadow region, acquired pictorial information precision can be thus influenceed, so as to influence accuracy of detection.
The theoretical conclusion obtained with experiment, the camera of two-way setting is when the pcb board to consistency of thickness take pictures operation
Preferably effect can be obtained, but after having changed the different pcb board of thickness, because focal length is different with illumination, shooting it is clear
Clear degree is by large effect, and the precision of detection can be also greatly reduced, so that needing to readjust camera and wiring board
Between focal length can attain the Way preferably accuracy of detection.
