Operation principle of the present utility model is: be placed in detection platform 1 by detected backlight module 4, simultaneously will be by
The power end 41 of the backlight module 4 of detection is with the positive pole copper sheet 31 detecting A plate 11, negative pole copper sheet 32 is corresponding electrically connects, and it is right to confirm
After standard is errorless, then transparent protective film 5 is covered on detected backlight module 4, is then turn on power supply and lights backlight module 4,
And start vacuum pump.Vacuum pump extracts detection A plate 11 cavity 112, adsorption hole 111 and inspection out by the through hole 121 of detection B plate 12
Survey the air between A plate 11 and transparent protective film 5 so that transparent protective film 5 is less than transparent towards the pressure of detection A plate 11 side
The pressure of protecting film 5 opposite side.Under the effect of pressure, transparent protective film 5 can be pressed on detection A plate 11 and detected backlight
On module 4, and backlight module 4 is produced disposable and omnibearing by pressure, and then replace scraper plate of the prior art operation
The white point of detection backlight module 4 is bad, foreign body is bad, white group is bad, thus overcomes scraper plate and detect the scuffing product caused
Defect；The relative position of product and detection tool can not be changed, it is ensured that product is good with contacting of detection tool simultaneously, it is to avoid
Cause the operation that need to repeat to light during scraper plate detection, improve work efficiency.
The backlight module detection tool that this utility model provides is by vacuum pump suction detection A plate 11 and transparent protective film 5
Between air so that transparent protective film 5 towards the pressure of detection A plate 11 side less than the pressure of transparent protective film 5 opposite side.
Transparent protective film 5 is pressed on detected backlight module 4 under pressure action so that backlight module 4 is capable of disposably
Comprehensive being pressed, to detect, the white point in backlight module 4 is bad, foreign body is bad, white group is bad；Simultaneously because of the detected back of the body
Light module 4 is comprehensive being pressed, during detection, and the power end 41 of detected backlight module 4 and the positive pole copper of detection A plate
Sheet 31, the relative position of negative pole copper sheet 32 will not be changed, and can avoid the backlight module being detected and contacting of detecting tool
Bad causing needs again to light, thus improves work efficiency.It should be noted that, this utility model can either play scraper plate inspection
The effect surveyed, the defect scratching product that scraper plate detection can be overcome again to be caused, cause during avoiding scraper plate detection simultaneously
Product and the loose contact detecting tool need the operation again lighted, and improve work efficiency.
Preferably, for reducing testing staff's scuffing to detected backlight module 4 further, improve work effect simultaneously
Rate.In the present embodiment, this utility model backlight module detection tool also includes the connection assembly being fixed on the bottom surface of detection B plate 12
6.Wherein, connect assembly 6 and include the first connector 61 and the second connector 62.First connector 61 cuts with scissors with the first support column 211
Connecing, the second connector 62 is hinged with the second support column 212.Specifically, the first connector 61 (is not shown in figure by the first bolt
Go out) hinged with the first support column 211；Wherein, the first connector 61 offers the first through hole 611, the first support column 211 away from
One end of base offers the second through hole 612；First bolt-through the first through hole 611 and the second through hole 612, and the first bolt
End and the first nut (not shown) connect.Second connector 62 is hinged by the second bolt and the second support column 212.Its
In, the second connector 62 offers third through-hole 621, the second support column 212 offers fourth hole away from one end of base
622；Second bolt (not shown) runs through third through-hole 621 and fourth hole 622, and the end of the second bolt and second
Nut (not shown) connects.It should be noted that, on detection platform 1 can make with the first bolt and the second bolt for the strong point
Lower flip-flop movement.After detected backlight module 4 is tightly adsorbed in detection platform 1 with transparent protective film 5, testing staff
, to adjust the position of detected backlight module 4 detected backlight module 4 can be entered by spinning upside down detection platform 1
The detection of row full visual angle.The hinged testing staff of avoiding between detection platform 1 and a support component 2 directly picks up the light of the detected back of the body
Module 4 carries out the detection of full visual angle, reduces testing staff's scuffing to detected backlight module 4, can improve work effect simultaneously
Rate.
Further, for convenience of the detection to detected backlight module 4 of the testing staff full visual angle, in the present embodiment,
The first support column 211 in backlight module detection jig base is contour with the second support column 212, the 3rd support column 213 and the 4th
Support column 214 is contour, and the first support column 211 is higher than the 3rd support column 213.First support column the 211, second support column 212 with
The difference in height of the 3rd support column the 213, the 4th support column 214 is so that backlight module 4 detected in detection platform 1 inclines
Tiltedly, testing staff can be with the luminous zone of the most detected convenient backlight module 4, to detect detected backlight module
4 bad.
Preferably, complete detection is not reached, specifically in order to avoid detected the be pressed power of backlight module 4 is uneven
Ground, adsorption hole 111 is evenly distributed on first of detection A plate 11.Equally distributed adsorption hole 111 can allow transparent protective film
Being uniformly distributed by pressure of 5 pairs of detected backlight modules 4, to avoid the backlight module 4 being detected to occur, local is pressed
Power is not enough and can not reach the Detection results of scraper plate tool.
The foregoing is only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model,
Every under inventive concept of the present utility model, the equivalent structure utilizing this utility model description and accompanying drawing content to be made becomes
Change, or directly/be indirectly used in other relevant technical fields and be included in scope of patent protection of the present utility model.
