The utility model embodiment is described in detail with reference to the accompanying drawings
Shown in please referring to Fig.1 to Fig.3, according to the backlight check device that the utility model embodiment provides, including support
Frame 10, jig 20 and transparent protective film 30.
Specifically, supporting rack 10 is used to support jig 20, which can be constructed differently to tie as needed
Structure, if can support jig 20 and make the jig 20 be maintained at certain altitude position.
Jig 20 includes the bearing seat being rotatably set on support frame as described above 10, and the upper surface of the bearing seat, which is equipped with, fits
It is laid in the rest area P01 for loading backlight to be checked and around the adsorption zone P02 of the rest area P01, the adsorption zone P02
Multiple adsorption holes 2011 being connected with vacuum source.
That is, the upper surface of bearing seat has in rest area P01 and adsorption zone P02, such as Fig. 1 examples, bearing seat
Construct it is rectangular, be located at bearing seat upper surface middle section be rest area P01, rest area P01 be rectangle, backlight to be checked
Source can install the rest area P01 for the upper surface for being fixed to bearing seat.And the neighboring area of centrally located areas outside is absorption
Area P02, adsorption zone P02 are placed with multiple adsorption holes 2011, adsorption hole 2011 and external vacuum source (such as vacuum pump) phase
Connection is vacuumized by vacuum source and each adsorption hole 2011 may make to generate negative-pressure adsorption effect when vacuum source works.
Bearing seat can relatively rotate on supporting rack 10, and the inclination of the bearing seat can be adjusted by rotating the bearing seat
Angle so that the inspection personnel facilitates the backlight to be checked observed on the bearing seat.
Transparent protective film 30 can at least cover the rest area P01 and adsorption zone P02, and be configured in the absorption
Hole 2011 compresses the backlight being bonded in the rest area P01 when generating vacuum suction effect.It is transparent in Fig. 1 examples
The area of protective film 30 and the area of the upper surface of bearing seat are of substantially equal, and the upper surface of bearing seat can just be completely covered.
When vacuum source works, each adsorption hole 2011 on adsorption zone P02 is made by the vacuum action of vacuum source
Suction-operated is generated, as long as at this point, when transparent protective film 30 is positioned over the upper surface of bearing seat, then transparent protective film 30
It is close to the upper surface of bearing seat under suction-operated.And the middle section of the upper surface of bearing seat is rest area P01, the rest area
Backlight is mounted in P01, so, transparent protective film 30 can generate downward pressure to backlight in the P01 of rest area so that the back of the body
The surface of light source generates a degree of compressing.
It should be noted that the surface of backlight should avoid part from pressing or apply excessive pressure, otherwise can cause
Its structural failure, and in the utility model, transparent protective film 30 is adsorbed by suction-operated, recycles transparent protective film 30 to the back of the body
Light source applies pressure will not damage backlight in this way, can so that pressure is uniform caused by local pressure.Meanwhile passing through vacuum
The adjusting in source can be conveniently adjusted suction-operated, that is, be applied to the pressure on backlight convenient for adjusting transparent protective film 30
Power.
The course of work of the backlight check device of the utility model embodiment is briefly described below.
First, backlight to be checked is fixedly installed to anti-rest area P01 on bearing seat, in installation between the P01 of rest area,
Need to check backlight surface with the presence or absence of dirt, foreign matter, dust etc., it, can be with for example, if there are dirt, foreign matter, dust etc.
It is cleaned, such as is blown by air pressure gun and to wipe the surface of backlight and cleaned with the surface to backlight.
Then, the golden finger on the FPC on backlight is connected to power supply, is provided for backlight by power supply
Operating voltage, so that backlight lights work.
Further, transparent protective film 30 is placed on to the upper surface of bearing seat, and ensures that the covering of transparent protective film 30 is put
Set area P01 and adsorption zone P02.
Further, each adsorption hole 2011 of adsorption zone P02 is vacuumized using vacuum source so that each adsorption hole
2011 generate suction-operated, and transparent protective film 30 is adsorbed on to the upper surface of bearing seat under the suction-operated of adsorption hole 2011,
At this point, transparent protective film 30 can generate downward pressure to backlight in the P01 of rest area so that the surface of backlight generates certain
The compressing of degree.
Finally, inspection personnel is by rotating bearing seat, and then adjusts the angle of bearing seat, and realization is observed under different angle
Backlight surface is with the presence or absence of bad problems such as foreign matter, white points.
According to the backlight check device that the utility model embodiment provides, the adsorption hole 2011 on bearing seat can be utilized
Transparent protective film 30 is adsorbed, so that transparent protective film 30 applies backlight surface certain pressure, in this way, working as backlight
When picture is lighted, the problems such as whether there is foreign matter and white point in the backlight can be intuitively told with simpler, improve the back of the body
The undesirable recall rate of light source foreign matter, white point, reduces the problem of bad products are flowed into market, moreover, detection efficiency is high, meets
The requirement of batch production.Meanwhile the pressure that transparent protective film 30 applies backlight surface is uniform, avoids manual pressure band
The damage risk come.In addition, bearing seat can rotate on supporting rack 10, in this way, being convenient to testing staff's adjustable visual angle, realize
No dead angle checks.
Optionally, perspex material, such as PET materials may be used in transparent protective film 30, the transparent protective film 30
Erroneous judgement when thickness should avoid blocked up, blocked up thickness from being likely to result in inspection, preferably, the thickness of the transparent protective film 30
For 0.05mm to 0.3mm, this thickness can either pack the durability of transparent protective film 30, meanwhile, it can also ensure to check backlight
The picture inspection quality in source reduces erroneous judgement, reaches high yields.
