A kind of camera module has the circuit board detection device of elevating function
Technical field
Wiring board detection field is the utility model is related to, more particularly to a kind of camera module has the wiring board of elevating function
Detection means.
Background technology
A kind of advanced online measuring technique of circuit board detection device, it obtain after the image information on detected member surface and
The image information of pieces O.K. is contrasted, so as to detect whether measured piece is qualified.At present, using for online optical detector is led
Domain is quite varied, such as detecting pcb board (i.e. printed circuit board (PCB)), due to pcb board is complicated, its designed lines is more and more,
The number of plies is also more and more, therefore ripe more than manual detection mode, efficient to detect pcb board used in line optics detector, so as to
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, first detects a table of pcb board
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
Enough and the factors such as shadow region be present, 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
Preferable effect can be obtained, but after having changed the different pcb board of thickness, because focal length and illumination are different, 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 preferable accuracy of detection.
