A kind of light guide plate inspection body
Technical field:
This utility model relates to light guide plate technical field, in particular to a kind of light guide plate inspection body.
Background technology:
Present LCD TV manufacturer commonly uses the higher blooming piece of penetrance, but, employ penetrance higher
Blooming piece after, i.e. the shielding of blooming piece is greatly reduced, and some flaws above original light guide plate all can be clearly
Present.So, in current printing industry, in order to more effectively the flaw above light guide plate be carried out blocking of leading portion
Cutting, some producers directly use backlight module to check.But, assemble frequently and disassemble, the corner of light guide plate and backlight mould
Group friction produces foreign body, can secondary pollution light guide plate.The producer also having uses the profile of bakelite tool simulation backlight module to carry out
Making, this scheme can be substantially reduced fricative hidden danger, but, because the eyes of reviewer are for a long time facing to LED, meeting
Cause the dimness of vision, the problem that the most i.e. can cause inspection leakage, meanwhile, also can the eyes of damage survey personnel.
Summary of the invention:
For the problems referred to above, this utility model provides following technical scheme:
A kind of light guide plate inspection body, including bottom bar, described bottom bar is bolted on pedestal by several, the described end
The top of bar is enclosed within sleeve, and sleeve is fixed with horizontal plate by bolt, and the lower section of described horizontal plate is provided with half gear, described set
The sidepiece of cylinder is provided with elongated portion, and the second motor is fixed in elongated portion, the installed above little gear of described second motor, described little
Gear and the engagement of half gear;The sidepiece of horizontal plate is provided with hang plate, passes through gemel connection between described hang plate and horizontal plate;Institute
The back stating hang plate is provided with the first straight-bar, and described straight-bar is hinged with tooth bar contiguous block, and described tooth bar contiguous block is fixed with tooth bar,
The other end of described tooth bar is connected to gear-box, and described first motor is arranged on the outer wall of gear-box.
By technique scheme, starting the first motor, the tooth bar in gear-box will elongation or contraction, gear-box and level
Plate is hinged, and gear-box is rotatable, and the tooth bar contiguous block of the tooth bar other end is also hinged with the first straight-bar, simultaneously hang plate and horizontal plate
Between by gemel connection, these three pin joint can make hang plate rotate along horizontal plate, so reaches to regulate Inclined Angle
Purpose, light guide plate is arranged on hang plate, the angle of scalable light guide plate, with facilitate inspection light guide plate whether there is the flaw
Defect.This mechanism also can carry out the regulation of horizontal direction simultaneously, i.e. starts the second motor, and little gear will rotate with half gear engagement,
Owing to sleeve is fixed with horizontal plate, therefore cause horizontal plate to rotate in the horizontal direction, can drive and tooth bar engaging elements simultaneously
Horizontal rotation, it is achieved mechanism's multi-angle regulation.
By technique scheme, can be prevented effectively from light guide plate industry because the eyes of reviewer are for a long time facing to luminescence
Source and cause the dimness of vision and then cause the situation of inspection leakage to occur, thus improve reviewer to the flaw above light guide plate
The recall rate of defect, meanwhile, protects again the eyes of reviewer.
As to the explanation of hang plate back structures in this utility model, the back of described hang plate is additionally provided with brace, institute
The quantity stating brace is two, and said two brace intersects to be installed.The back of described hang plate is additionally provided with the second straight-bar, and described
Two straight-bars and two braces are arranged in a crossed manner, and a blade of described hinge is arranged on the second straight-bar, and another blade is arranged on
On horizontal plate.Hang plate can be played the effect increasing intensity by two braces arranged in a crossed manner at hang plate back, passes through hinge
The second straight-bar connected and horizontal plate, can make to promote hang plate to regulate angle along hinge in the case of tooth bar elongation or contraction
Degree, automaticity is high.
As the explanation to this utility model middle rack kind of drive, the outfan of described first motor is provided with gear, should
Wheel and rack engages, and described tooth bar may pass through gear-box.Described gear-box is hinged with horizontal plate, and described gear-box can be in level
Rotate in plate.The first motor pushing tooth bar elongation or contraction when, tooth bar contiguous block can rotate along the first straight-bar, with
Time gear-box also can rotate along horizontal plate, to adapt to the change of tooth bar length.

Detailed description of the invention:
As shown in Figure 1 to Figure 3, a kind of light guide plate inspection body, including bottom bar 10, described bottom bar 10 is solid by several bolts
Being scheduled on pedestal, the top of described bottom bar 10 is enclosed within sleeve 11, and sleeve 11 is fixed with horizontal plate 26 by bolt, described water
The lower section of flat board 26 is provided with half gear 260, and the sidepiece of described sleeve 11 is provided with elongated portion, and the second motor 28 is fixed on elongated portion
On, the installed above little gear 29 of described second motor 28, described little gear 29 engages with half gear 260;The side of horizontal plate 26
Portion is provided with hang plate 20, is connected by hinge 270 between described hang plate 20 and horizontal plate 26;The back of described hang plate 20 sets
Having the first straight-bar 22, described straight-bar 22 is hinged with tooth bar contiguous block 23, and described tooth bar contiguous block 23 is fixed with tooth bar 24, described tooth
The other end of bar 24 is connected to gear-box 240, and described first motor 25 is arranged on the outer wall of gear-box 240.
As in figure 2 it is shown, the back of described hang plate 20 is additionally provided with brace 21, the quantity of described brace 21 is two, described
Two braces 21 intersect to be installed.
As in figure 2 it is shown, the back of described hang plate 20 is additionally provided with the second straight-bar 27, described second straight-bar 27 and two braces
21 is arranged in a crossed manner, and a blade of described hinge 270 is arranged on the second straight-bar 27, and another blade is arranged on horizontal plate 26
On.
As shown in Figure 3 and Figure 4, the outfan of described first motor 25 is provided with gear, and this wheel and rack 24 engages, described
Tooth bar 24 may pass through gear-box 240.
As shown in Figure 3 and Figure 4, described gear-box 240 is hinged with horizontal plate 26, and described gear-box 240 can be at horizontal plate 26
Interior rotation.
In real work, starting the first motor 25, the tooth bar 24 in gear-box 240 will elongation or contraction, gear-box 240
Hinged with horizontal plate 26, gear-box 240 is rotatable, and the tooth bar contiguous block 23 of tooth bar 24 other end is also hinged with the first straight-bar 22,
Being connected by hinge 270 between hang plate 20 and horizontal plate 26, these three pin joint can make hang plate 20 along horizontal plate simultaneously
26 rotate, and so reach to regulate the purpose of hang plate 20 angle, are arranged on by light guide plate on hang plate 20, scalable light guide plate
