Abstract
The utility model provides a light guide plate parameter test tooling, characterized in that a guide rail is arranged on a bottom plate and is perpendicular to a first strip light installing plate, and a second strip light installing plate slides along the guide rail. By employing the light guide plate parameter test tooling, one tooling can test various types of light guide plates, and each type of light guide plate does not need to wait the processing of the respective test tooling after being produced, thereby saving the cost, shortening the test cycles of the light guide plates, and accelerating the overall production schedule of a liquid crystal screen.
Description
Technical field
The utility model relates to a kind of LGP parameter testing frock.
Background technology
In the exploitation of the side entering type liquid crystal module of routine, all can use LGP, the parameters of LGP has fundamental influence to the imaging effect of whole LCD screen, especially the parameter of LGP.The LGP test fixture mainly is the user mode of analog light source and LGP, the optical property of test LGP.And present LGP test fixture structural member all is the production method that adopts the die sinking tool, and a kind of test fixture can only be applied to a kind of LGP of model, can't be general.Both consumed wide variety of materials, prolonged the test period of LGP again, production efficiency is reduced.
The utility model content
The utility model technical matters to be solved provides a kind of LGP parameter testing frock, and this LGP parameter testing frock is applicable to the test job of multiple LGP.
The technical scheme that the utility model technical solution problem is adopted is: this LGP parameter testing frock; Comprise base plate; Said base plate is provided with the first lamp bar installing plate and the second lamp bar installing plate that is used to install LED lamp bar; On said base plate, also be provided with guide rail, said guide rail is perpendicular to the first lamp bar installing plate, and the said second lamp bar installing plate slides along guide rail.The second lamp bar installing plate slides into the relevant position according to the size of tested LGP, cooperates with the first lamp bar installing plate tested LGP location.
More steady for guaranteeing that the second lamp bar installing plate slides, direction non-migration, said guide rail are two, and parallel to each other.
Also be provided with cover plate on the said first lamp bar installing plate and the second lamp bar installing plate, prevent that LED lamp bar receives damage.
Lower surface at said cover plate is provided with convexity, and said convexity can be pushed down LGP, prevents LGP play in test process.
The beneficial effect of the utility model is: after adopting this kind LGP parameter testing frock; One cover frock can be tested the LGP of multiple model; After producing, need not wait the LGP of different model machining of separately test fixture; Both practice thrift cost, shortened the test period of LGP again, accelerated the production progress of liquid crystal display.

Fig. 1 is the utility model LGP parameter testing frock schematic three dimensional views.
Fig. 2 is the vertical view of the another kind of structure of the utility model LGP parameter testing frock.
Fig. 3 partly cuts open figure along A-A line among Fig. 2.
Fig. 4 is the partial enlarged drawing at B place among Fig. 3.
Embodiment
When the optical parametric of test LGP 8, need frock to confirm the position of LED lamp bar 5 and LGP 8, the light that LED lamp bar 5 is sent is that the user mode according to finished product incides in the LGP 8.As shown in Figure 1, this LGP parameter testing frock is provided with guide rail 4, the first lamp bar installing plates 2 in increase on the base plate 1 and is fixed on the base plate 1, and the second lamp bar is installed version 3 and can be slided along guide rail 4, to adapt to the demand of different model LGP 8.
For making the second lamp bar the more steady of version 3 slips is installed; Guide rail 4 is set to two; And it is parallel to each other and version 2 is installed perpendicular to the first lamp bar; All the time that version 2 is installed is parallel with the first lamp bar in sliding process so the second lamp bar is installed version 3, and the light vertical irradiation that has guaranteed LED lamp bar 5 is to LGP 8.
As shown in Figures 2 and 3, increase is provided with cover plate 6 on the first lamp bar installing plate 2 and the second lamp bar installing plate 3, and protection LED lamp bar 5 can not damage because of external force.As shown in Figure 4, cover plate 6 is structure as a whole with lamp bar installing plate, has simplified annexation, reduced installation steps, and intensity is higher, processes also simpler.Lower surface at cover plate 6 is provided with protruding 7; LGP 8 is packed into after the frock; Clamped with base plate 1 by protruding 7, make LGP 8 that play not take place in test process, LGP 8 is stable with the relative position of LED lamp bar 5; Guaranteed that light direction when test that LED lamp bar 5 sends can not squint, thereby test result is more accurate.
