It is demarcated with the second vision-based detection mechanism 86, it is specific as shown in Figure 10.Upper detection vision system camera and lower detection in Figure 10
Vision system camera respectively represents the detection camera of First look testing agency 85 and the second vision-based detection mechanism 86, calibration process
It is as follows：An arbitrarily selected calibration point on liquid crystal display panel, support plinth 81 drive First look testing agency 85 and second to regard
Feel that testing agency 86 moves, by the detection camera of First look testing agency 85 and the second vision-based detection mechanism 86 respectively to liquid crystal
Panel is shot, obtain calibration point on liquid crystal display panel upper imaging area (imaging area of First look testing agency 85) and under
Position in imaging area (imaging area of the second vision-based detection mechanism 86), then with the phase of calibration point position and picture centre
To position, on the basis of the detection camera of the second vision-based detection mechanism 86, the position of adjustment First look testing agency 85 makes the
The central axis of the detection camera 7 of one vision-based detection mechanism 85 and the second vision-based detection mechanism 86 overlaps, and by adjusting machine
Structure 84 adjusts the position of First look testing agency 85 in the vertical direction, keeps imaging most clear, completes calibration.
The second module 8 of the present invention, can also be right before to liquid crystal display panel and then secondary positioning after completing to demarcate
Liquid crystal display panel carries out stitching state detection.As shown in figure 11, due to liquid crystal display panel generally include upper and lower surfaces board group at, above
Plate is equipped with multiple protrusions, and lower panel is equipped with multiple recess corresponding with protrusion, is realized by the cooperation of protrusion and recess
The fastening of top panel and lower panel.The second locating module of the present invention can be detected the fastening quality of liquid crystal display panel, right
The fastening quality testing process of liquid crystal display panel is as follows：It can be at top panel protrusion certain distance (distance can arbitrarily be set)
A selected upper calibration point, is selecting a lower calibration point at lower panel recess certain distance (distance can arbitrarily be set),
Upper position of the calibration point in upper imaging area is obtained by First look testing agency 85, is obtained by the second vision-based detection mechanism 86
Remove position of the calibration point in lower imaging area, you can exist to obtain upper deviation and lower calibration point of the calibration point in upper imaging area
Deviation in lower imaging area, in conjunction with selection upper calibration point at a distance from protrusion, lower calibration point is at a distance from recess, you can it is right
The chimeric degree of top panel and lower panel makes judge.
