Description
Technical field
The utility model relates to back light model setting technology field more particularly to a kind of backlight filth test jigs.
Background technique
In liquid crystal display die set industry, when being assembled to backlight module, need to check backlight surface whether
There is foreign matter (such as dust, fiber hair, jelly) or scratch, common way is directly to light backlight module, is seen by worker
Examine whether backlight module surface has foreign matter or scuffing, in this way, backlight module pierces very much after lighting since light is too bright
Eye, backlight module surrounding edge can blind area easy to form cause to check less than and more small foreign matter is also easy due to light
Too bright and missing inspection；It checks human eye long working, also be easy to cause visual fatigue.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of backlight filth test jig.
The technical solution of the utility model is as follows: the utility model provides a kind of backlight filth test jig, comprising: base
Seat, is set to described pedestal one end end at the sliding bottom on the pedestal, the work top on the sliding bottom
Light source bracket, the light source base that is mounted on the light source bracket and the light source for being mounted on the light source seating face, the pedestal
Surface is formed with sliding rail, and the sliding bottom corresponds to the sliding rail equipped with slide unit, and the sliding bottom can be on the pedestal
Sliding is so as to adjust the relative distance with the light source, the light of the light source green-emitting.
Further, the light source is several LED light.
Further, several LED light are uniformly arranged on the light source base.
Further, the light source base is fixed by screw mode and mutually fixes with the light source bracket.
Further, vertical mounting groove is formed on the light source base, installation screw is locked after passing through the mounting groove
In on the light source bracket, to the light source bracket and light source base are fixed, the height of the light source base installation site
It can be adjusted according to position of the installation screw in mounting groove.
Using the above scheme, the utility model structure is simple, and cost is relatively low, can be convenient to backlight surface with the presence or absence of different
Object is checked, while can be mitigated personnel labor intensity and be promoted checkability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the utility model backlight supporting structure schematic diagram.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of backlight filth test jig, comprising: pedestal 1 is set to the pedestal 1
On sliding bottom 2, the work top 3 on the sliding bottom 2, the light source bracket set on 1 one end end of pedestal
4, the light source base 5 that is mounted on the light source bracket 4 and the light source 6 for being mounted on 5 surface of light source base, 1 surface of pedestal
It is formed with sliding rail 11, the corresponding sliding rail 11 of the sliding bottom 2 is equipped with slide unit, and the sliding bottom 2 can be in the pedestal 1
Upper sliding is several LED light so as to adjust the relative distance with the light source 6, the light of 6 green-emitting of light source, the light source 6,
Several LED light are uniformly arranged on the light source base 5.The light source base 5 can also be arranged in 6 upper and lower ends of light source
Lampshade, so that light only emits to certain orientation.
Fig. 1 and Fig. 2 are please referred to, the light source base 5 is fixed by screw mode and fixes with 4 phase of light source bracket.
Vertical mounting groove 41 is formed on the light source base 5, installation screw 7 lock onto the light source branch after passing through the mounting groove 41
On frame 4, so that the light source bracket 4 and light source base 5 are fixed, the height of 5 installation site of light source base can basis
The position of the installation screw 7 in the mounting groove 41 adjusts, and the angle of the light source base 5, can also by
The angle of the light source base 5 is kept when installation, then tightens the mode of the installation screw 7 to control the angle of the light source base 5.
When this equipment works, the light source 6 issues parallel green light, and backlight module is placed on the work top 3, makes
The light source 6 is obtained with the work top 3 in about 20-30 ° of angle, then makes the sliding bottom 3 along the sliding rail 11
Sliding, so that light is radiated on backlight module, testing staff's eyes and backlight module are about in 45 degree, be can be convenient to backlight module
Whether surface has foreign matter to be checked.Since green light is the shorter light of wavelength reflection in visible light, and color is soft does not hurt eye,
The degree of fatigue of staff can be mitigated.
In conclusion this device structure is simple, cost is relatively low, can be convenient and examines to backlight surface with the presence or absence of foreign matter
It looks into, while personnel labor intensity can be mitigated and promote checkability.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
