700 are defined in specified location, and limiting section can be adjusted with to various sizes of backlight to be measured in movement on carrying platform 101
Module 700 carries out spacing, the actual bearer region of adjustment carrying platform 101.Specifically, carrying platform 101 is provided with limited block
1012 and slide rail 1011, this limited block 1012 be fixed on using screw on slide rail 1011, during detection, backlight module 700 be placed in by
In the specified location that limited block 1012 limits, when the size of backlight module 700 to be measured changes, it can first unscrew screw, will limit
Position block 1012 slides into suitable position, then tightens screw again and retightens limited block 1012 on slide rail 1011,
Thus, carrying platform 101 can reliablely and stablely carry various sizes of backlight module to be measured 700.
In addition, there is the emergency to happen suddenly to tackle backlight module detection arrangement 1000, Fig. 5, backlight mould refer to
Set detecting device 1000 also includes control panel 600, and control panel 600 couples with control unit (not shown), control panel 600
Scram button 601 and SR 602 are provided with, when scram button 601 is used in detection process break down, forces to stop
Workbench 100, SR 602 reset workbench 100 after being used for Failure elimination.It is normal in backlight module detection arrangement 1000
During work, workbench 100 can automatically rotate according to the program of setting, when a failure occurs it, can pass through scram button the last 601
Stop table 100 processed, makes it stop operating,, can be by multiple after failure to be repaired to prevent personnel from injuring and damage of product
Position button 602 causes the automatic rotation again of workbench 100.
Including the first carrying platform 101a and the second carrying platform 101b below with workbench 100, (i.e. workbench 100 includes
The situation of two carrying platforms 101) exemplified by backlight module detection process is discussed in detail：Identity-acquiring unit 200 and IMAQ
The position of unit 300 is fixed, and during original state, the first carrying platform 101a is located at the lower section of identity-acquiring unit 200, and second
Carrying platform 101b is located at the lower section of image acquisition units 300, and a backlight module 700a to be measured is had to the one side of patch material
(i.e. the back side) is placed in the first carrying platform 101a (now the second carrying platform 101b does not carry backlight module also) and by body upward
Part collecting unit 200 gathers above-mentioned backlight module 700a to be measured identity coding (as shown in Figure 1), and by identity coding send to
Processing unit 400, then control unit according to the instruction of processing unit 400 control rotating mechanism rotate, above-mentioned treat will be carried
A rotates 180 degree to the lower section of image acquisition units 300 to survey backlight module 700a the first carrying platform 101a along clockwise direction
(as shown in Fig. 2 now the second carrying platform 101b is located at the lower section of identity-acquiring unit 200), image acquisition units 300 gather
And obtain the above-mentioned backlight module 700a to be measured actual image in surface, and send handled to processing unit 400 and judge with
And send to display unit 500 and shown, at the same time, staff, which has another backlight module 700b to be measured, attaches material
The one side (i.e. the back side) of material is placed in the second carrying platform 101b and gathers above-mentioned another back of the body to be measured by identity-acquiring unit 200 upward
Optical mode group 700b identity coding (as shown in Figure 2), and this identity coding is sent to processing unit 400, it is above-mentioned another to detect
