Abstract
The utility model provides a testing tooling of a light guide plate. The testing tooling of the light guide plate is characterized in that a locating column is cancelled; limiting manner of the light guide plate and arrangement of a limiting device are changed; the original screw connection device is utilized; a fixing screw is a limiting screw; and the top of a nut is contacted with the light guide plate, so that a distance exists between the light guide plate and an LED (Light Emitting Diode) lamp body. The tooling and the light guide plate are simpler in structure and shorter in processing period; furthermore, a limiting structure is arranged between the light guide plate and the LED lamp; therefore, even in the presence of processing error, the distance existing between the light guide plate and the LED lamp body can also be ensured, thus, the testing efficiency is increased.
Description
Technical field
The utility model relates to a kind of LGP test fixture.
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.When the test LGP, just need a frock to simulate the light guide effect of LGP.In frock, be provided with LED lamp, make to be screwed, and need have certain distance between LED lamp and the LGP as light source.Present LGP test fixture structural member all is the production method that adopts the die sinking tool; Confirm the position relation of LGP and LED lamp through the limited post on the frock; Screw only plays the effect of fixed L ED lamp, and LGP also need be provided with spacing hole or the groove with the limited post coupling.The complexity that this has just increased frock and LGP has prolonged the process-cycle, and production efficiency is reduced.And present position limiting structure all is arranged on the both sides that the LED lamp is not installed on the frock, if the groove on reference column or the LGP man-hour occurs error adding, LGP will touch the LED lamp, influence test effect.
The utility model content
The utility model technical matters to be solved provides a kind of LGP test fixture, and this LGP test fixture has been cancelled reference column, adopts screw spacing, simple in structure, and has avoided the influence of mismachining tolerance.
The technical scheme that the utility model technical solution problem is adopted is: this LGP test fixture comprises frock main body and lamp bar; Said lamp bar is fixed on the said frock main body through several gib screws; Said lamp bar is provided with the LED lamp body, and said lamp bar gib screw is a stop screw, and head of a nail top contacts with LGP; There is distance in the upper surface of head of a nail top and LED lamp body, LGP be close to behind the stop screw will and the LED lamp body between a segment distance is arranged.
The beneficial effect of the utility model is: this LGP test fixture has changed the layout to the limit method and the stop means of LGP; Utilize original screw coupling arrangement; Corresponding spacing hole or groove on limited post and the LGP on original frock have been cancelled; Make the structure of frock and LGP more simple, the process-cycle is shorter.And position limiting structure is arranged between LGP and the LED lamp, even there is mismachining tolerance like this, also can guarantee to have distance between LGP and the LED lamp body.Owing to no longer need the accurate localization device between LGP and the frock, thus install and when taking off LGP operational motion simple, improved efficient.
Description of drawings
Fig. 1 is the utility model LGP test fixture vertical view.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Embodiment
As shown in Figure 1, LGP 5 need be installed in when testing in the frock main body 1, is provided with lamp bar 2 in the one or both sides of LGP 5.As shown in Figure 2, be installed on the lamp bar 2 through gib screw 3 as the LED lamp body 4 of analog light source, shine LGP 5 from the side according to test request.After LGP 5 was put into frock, the side of LGP 5 contacted with head of a nail top, had distance between plane, head of a nail top place and LED lamp body 4 upper surfaces, still and between the LED lamp body 4 slit was arranged after making the side of LGP 5 be adjacent to the head of a nail.Because the lamp bar 2 of the same side is provided with a plurality of gib screws 3, so even one of them mismachining tolerance occurs, LGP 5 can not touch LED lamp body 4 yet.Both simplify the structure of frock main body 1 and LGP 5, reached test request again.
Claims (1)
1. LGP test fixture; Comprise frock main body (1) and lamp bar (2); Said lamp bar (2) is fixed on the said frock main body (1) through several gib screws (3), and said lamp bar (2) is provided with LED lamp body (4), it is characterized in that: said gib screw (3) is a stop screw; Head of a nail top contacts with LGP (5), and there is distance in the upper surface of head of a nail top and LED lamp body (4).
