Frequency is 2500 times/second；The transfer rate of described roller conveying device is 6 ms/min.
It is interlaced setting that described A-wire, which stitches the bright light of both light extraction stroboscopic lamp and second linear slit light extraction stroboscopic lamp, turned off the light,
's.
The beneficial effects of the invention are as follows：Due to the roller conveying device 4 including being erected on long square frame-shaped chassis 5, pass through
Side stand 6 be erected at the square surrounding frame frame 3 of the top of roller conveying device 4, the adjustable roof beam structure 1 for being erected at the top surface of peripheral frame frame 3, with can
Multiple high frequency line scan cameras 2 being distributed by linear array of the connection of roof beam structure 1, fore-and-aft clearance distribution frame are adjusted to be scanned located at high-frequency line
A-wire seam light extraction stroboscopic lamp 9 and second linear slit between 4 overall top surface of the array entirety bottom surface of camera 2 and roller conveying device go out optical frequency
Flashing light 11, pattern recognition system, controller；The pattern signal output end of high frequency line scan camera 2 and pattern recognition system it is defeated
Enter end connection；Global focus line, the caustic of A-wire seam light extraction stroboscopic lamp 9, the second linear slit of the array of high frequency line scan camera 2 go out optical frequency
The caustic three of flashing light 11 is crossed in glass screen 8 for optically focused alignment line 10.
So, the photo figure of whole 8 each segment of glass screen can be preset in it is qualified small in pattern recognition system
The standard photographs figure of section is compared, and controller is commented automatically according to the quantity of unqualified segment in whole glass screen 8
Level is graded, and automaticity is high, detection efficiency is high, the relatively more objective comprehensive glass screen on-line measuring device of grading, uses
Effect is more preferable.
