Embodiment
About technology contents of the present utility model and detailed description, existing accompanying drawings is as follows:
Fig. 1 to Fig. 6 is that backlight module machines of the present utility model is formed structural representation.As shown in the figure, backlight module machines of the present utility model comprises: board 1, and the carrier 2 that can on board 1, move horizontally, in conjunction with the light detection module 3 that is disposed on the board 1 and has automatic focusing, focusing function, thereby can carry out Defect Detection, and can directly be sent to the maintenance station by network, for the maintenance personal provides the necessary coordinate data to carry out follow-up repairing with detecting data, simultaneously can carry out digitizing to the outward appearance flaw, to reduce artificial erroneous judgement, to improve the production quality.
Board 1, be provided with the platform 10 of transmission module (all not shown among the figure) in the surface configuration of its board body 11, above platform 10, be provided with upper casing 12, upper casing 12 forms accommodation space 13, accommodation space 13 collocation have dustless equipment 4, below dustless equipment 4, dispose at least more than one light detection module 3, in addition configurable at least one monitoring unit 5 and input block 6 in the outer face of upper casing 12 bodies.
Carrier 2 is used to place treats that detected backlight module 7, carrier 2 are driven by described transmission module and can move horizontally on platform 10, backlight module 7 can be entered or by the testing scope on the platform 10.
Photodetection assembly 31 (CCD) and the pedestal 32 in order to provide photodetection assembly 31 automatic focusings to move are provided light detection module 3, pedestal 32 is provided with at least one surperficial guide rails 33, dispose moving member 34 on the guide rails 33, be set with adaptor 35 on the moving member 34, in order to affixed photodetection assembly 31.
The testing result of photodetection assembly 31 will further be carried out datumization by monitoring unit 5 and be handled, as coordinatograph data etc., and can utilize network or wireless communication technology to be sent to assigned address by monitoring unit 5 and carry out record, perhaps be sent to maintenance department, handle directly to carry out correct repairing according to data.
Monitoring unit 5 can be computing machine, processor of single chip computer, wherein a kind of of the computing machine, processor of single chip computer etc. that perhaps has a display.Input block 6 is a keyboard.
Fig. 7, Fig. 8 are the detection focusing action synoptic diagram of backlight module machines of the present utility model.As shown in the figure, photodetection assembly 31 of the present utility model, be incorporated into pedestal 32 by moving member 34, and form by guide rails 33 and to vertically move guiding, under the control of software, when the carrier 2 that is equipped with backlight module 7 moves on platform 10 or passes through the light detection zone, can focus automatically by 31 pairs of backlight modules 7 of photodetection assembly, detect after obtaining pinpointed focus, further to carry out outward appearance.
