Main control unit sends idsplay order, the electricity to be measured by measurement of the display characteristics control panel 32 to circuit board under test 7
Road plate 7 is shown according to idsplay order control display screen 71；
The display performance of acquisition module collection display screen 71 is simultaneously uploaded to main control unit；
Main control unit is contrasted information is gathered with prestored information, to judge the display of the display screen 71 of circuit board under test 7
Whether performance is qualified.
Specifically, in measurement of the display characteristics device 3, display measurement jig includes track belt, track cylinder, display
Test needle bed, baffle plate, baffle plate cylinder, pressing plate, front end sensors and sensors in place；Pressing plate be fixed on track belt and with
The lifting of track belt one.Measurement of the display characteristics is first carried out in test step：The circuit board under test 7 sent out by programming device 2 leads to
Track Belt Conveying is crossed to region to be measured；After circuit board under test 7 enters region to be measured, front end sensors are triggered, display property
The controlling baffle plate cylinder action of energy test controller 34, baffle plate cylinder driving baffle plate ascend into region to be measured；When circuit board under test 7
Sensors in place is triggered when touching baffle plate, measurement of the display characteristics controller 34 controls track belt out of service, and controls track
Cylinder acts, and declines track belt, because pressing plate is fixed on track belt, pressing plate pushes down the both sides of circuit board under test 7 with rail
Road belt declines together, until the display test interface of the probe contact measured circuit board 7 of display test needle bed, track belt stop
Only decline.
Display test needle bed connects foregoing measurement of the display characteristics control panel 32 by lead, in circuit board under test 7 in place
Afterwards, measurement of the display characteristics controller 34 instructs to the output display of measurement of the display characteristics control panel 32, measurement of the display characteristics control panel
Idsplay order is sent to circuit board under test 7 by 32, and circuit board under test 7 is shown according to idsplay order control display screen 71, is
Ensure the accuracy of test, usually require that display screen 71 sequentially shows multiple different numerals, for example test program setting is aobvious
Display screen 71 shows 8,2,6 three numerals successively, in actual test, only display screen 71 in that same order complete display 8,2,
6 three numeral it is just qualified, if display order mistake, show numeric error or display brightness/color it is defective be not
It is qualified；Display screen 71 often shows a numeral, and camera 33 all carries out once photo taking, and image data is uploaded on measurement of the display characteristics
Position machine 31, to the image data of upload and the standard information to prestore according to above-mentioned criterion in measurement of the display characteristics host computer 31
Contrasted, thus judge whether the display performance of circuit board under test 7 is qualified.
