On band 61, pressing plate 65 is pushed down the both sides of circuit board under test 7 and declined with track belt 61, until the spy of display test needle bed 60
The display test interface of pin contact measured circuit board 7, track belt 61 stop declining.
Display test needle bed 60 connects foregoing measurement of the display characteristics control panel 2 by lead, in circuit board under test 7 with showing
After showing the probe contact of test needle bed 60, controller 3 is instructed to the output display of measurement of the display characteristics control panel 2, and display performance is surveyed
Idsplay order is sent to circuit board under test 7 by examination control panel 2, and circuit board under test 7 is carried out according to idsplay order control display screen 71
It has been shown that, in order to ensure the accuracy of test, usually require that display screen 71 sequentially shows multiple different numerals, such as test program
Setting display screen 71 show 8,2,6 three numerals successively, and in actual test, only display screen 71 completely shows in that same order
Show that 8,2,6 three numerals are just qualified, if display order mistake, display numeric error or display brightness/color are defective
It is unqualified；Display screen 71 often shows a numeral, and camera 5 all carries out once photo taking, and image data is uploaded to host computer 1,
The image data of upload is contrasted with the standard information to prestore according to above-mentioned criterion in host computer 1, thus judges to treat
Whether the display performance of the display screen 71 of slowdown monitoring circuit plate 7 is qualified.
Test result is understood in time for ease of tester, and host computer 1 is additionally provided with display 4, the test that host computer 1 is drawn
As a result can be shown by display 4, can be to be measured to this polylith in the case where having polylith circuit board under test 7 while testing
Circuit board 7 is numbered successively, on the test program interface of display 4, by the test knot of the circuit board under test 7 of reference numeral
Fruit is identified, qualified to be shown with green light, unqualified, is shown with red light.Unqualified reason and picture store automatically, so as to
Later stage is traced, and these test datas be able to can also upload onto the server, so as to subsequent calls, judgement, mark.
After the completion of measurement of the display characteristics, reply host computer 1 and complete signal, controller 3 controls track cylinder 62 to act, makes rail
Road belt 61 rises, and then controls track belt 61 to start, bracket 8 is sent out together with circuit board under test 7 from plate outlet 612, entered
Enter other processes.
In the case where polylith circuit board under test 7 is tested simultaneously, if taken pictures using a camera, it is desirable to shooting figure
The display performance of all circuit board under test display screens can be included in piece, the picture quality of collection can be caused to decline, increase identification is difficult
Degree, therefore, two cameras 5 are provided with the present embodiment, the corresponding four pieces of circuit board under test display screens 71 of collection of each camera 5 show
Show performance, it is ensured that can react four pieces of circuit board under test display screens clearly, exactly in the pictorial information acquired in each camera 5
71 display performance, in the case where meeting the requirement of polylith circuit board under test 7 while test, and can ensures picture quality of taking pictures.Thus
Those skilled in the art are it is also contemplated that using four cameras, the corresponding two pieces of circuit board under test display screens of collection of each camera show
Show performance, such scheme is also all in the scope of protection of the utility model.
