Abstract
The utility model discloses a kind of light guide plate detecting tool, comprise side base plate (10), be arranged on the lamp bar (20) on side base plate (10) one side, also comprise back up pad (30), described back up pad (30) makes described side base plate (10) certain angle that tilts, the height on one side of described side base plate (10) upper installation lamp bar (20) is lower than the height of its opposite side (11), and described lamp bar (20) light is along the surperficial directive oblique upper of described side base plate (10).Back up pad is by the side base plate that lamp bar is installed certain angle that tilts; make to install on side base plate the height on one side of lamp bar lower than the height of its opposite side; lamp bar light is along described side backplate surface directive oblique upper; so design; can effectively avoid the eyes because of reviewer in light guide plate industry facing to light emitting source, to cause the situation of check leakage to occur for a long time, protect again reviewer's eyes.
Description
Technical field
The utility model relates to serigraphy light guide plate industry, in particular to a kind of light guide plate detecting tool.
Background technology
Along with the thinner lighter development trend of liquid crystal industry, the light guide plate parts reductions of carrying out thickness too, light guide plate is down to 2mm from original 6mm, the higher requirement that this has proposed printing technology quality.
For the market in amiable market, each LCD TV producer has all carried out significantly promoting to the brightness of TV.Lifting brightness originally can only increase the granule number of LED reaches, and so can increase the cost of TV.So industry substitutes original scheme with the higher blooming piece of penetrance now.But, used after the blooming piece that penetrance is higher, the covering property of blooming piece is reduced greatly, and some flaws above original light guide plate all can clearly present.So in current printing industry, for the more effective interception of flaw above light guide plate being carried out to leading portion, some producers are directly used backlight module inspection.But assembling is disassembled frequently, the corner of light guide plate and backlight module friction produce foreign matter, can secondary pollution light guide plate.The producer also having is used the profile of bakelite tool simulation backlight module to make, this scheme can reduce fricative hidden danger greatly, but, because reviewer's eyes are for a long time facing to LED lamp, can cause the dimness of vision, the long-time problem that can cause check leakage, meanwhile, eyes that also can damage survey personnel.
How, meeting under the prerequisite of the high requirement that liquid crystal industry proposes printing technology quality, can make reviewer effectively the flaw above light guide plate be carried out to the interception of leading portion, be a technical matters urgently to be resolved hurrily.
Granted publication CN202216914U, the utility model in May 9 2012 Granted publication day discloses a kind of Photometry inspection device, comprises photometry tooling base and is arranged on the light emitting source on photometry tooling base, and it is as the light source of photometry work base.By using the Photometry inspection device of this utility model, mark analysis, identification inspection ability that light guide plate detects can have been improved.But the Photometry inspection device described in this utility model belongs to the detecting tool of horizontal lying-type, reviewer's eyes facing to light emitting source, can cause the dimness of vision for a long time equally, and then cause the problem of check leakage, meanwhile, and eyes that also can damage survey personnel.
Summary of the invention
The technical matters that the utility model solves: design a kind of light guide plate detecting tool, avoid the eyes because of reviewer in light guide plate industry to cause check leakage facing to light emitting source for a long time.
The utility model provides following technical scheme: a kind of light guide plate detecting tool, comprise side base plate, be arranged on the lamp bar on side base plate one side, also comprise back up pad, described back up pad makes described side base plate certain angle that tilts, the height on one side of lamp bar is installed lower than the height of its opposite side on described side base plate, described lamp bar light is along described side backplate surface directive oblique upper.
In technique scheme, back up pad is by the side base plate that lamp bar is installed certain angle that tilts, make to install on side base plate the height on one side of lamp bar lower than the height of its opposite side, lamp bar light is along described side backplate surface directive oblique upper, so design, reviewer is when check light guide plate, and eyes neither can directly face toward lamp bar, can test by the light source penetrating obliquely upward again.Pass through technique scheme; can effectively avoid the eyes because of reviewer in light guide plate industry facing to light emitting source, to cause the dimness of vision for a long time and then cause the situation of check leakage to occur; thereby promoted the recall rate of reviewer to the flaw above light guide plate; simultaneously; reviewer's eyes have been protected again; therefore, the utlity model has useful technique effect.
As further improvement of the utility model, described lamp bar is LED lamp bar.
As further improvement of the utility model, described back up pad makes described side base plate inclination 45 degree.In check light guide plate, both guaranteed that reviewer's eyes can directly not face toward LED lamp, guarantee again to test by the light source penetrating obliquely upward, side base plate inclination 45 degree are optimal design.
As further improvement of the utility model, described lamp bar is arranged on one side of described side base plate by lamp bar load bearing component.
As further improvement of the utility model, the rectangular triangle in the side of described back up pad, the quantity of described back up pad is three, and described back up pad is parallel to each other, and the spacing between every two of described back up pad equates.So design can make light guide plate detecting tool more firm.
As further improvement of the utility model, also comprise base plate, described side base plate is arranged on described base plate by back up pad.Described base plate bottom surface comprises back-up block.
