Assembly fixture

Abstract

An assembly jig includes a bearing plate, a base, a first elastic piece, two pairs of sliding blocks opposite to each other and a second elastic piece connected with the sliding blocks. The carrying plate is used to place a reflection sheet and a light guide plate, and at least one positioning column is arranged on the carrying plate. The bearing plate includes opposite first side walls and opposite second side walls adjacent to the first side walls, the first side walls are respectively provided with notches, and the outer sides of the second side walls are respectively facing A pressing plate is extended outward. A groove is provided on the base, one end of the first elastic member is held against the bottom surface of the bearing plate, and the other end is accommodated in the groove. One end of the slider is accommodated in the base, and the other end is accommodated in the notch. In the assembly jig of the present invention, when the bearing plate is pressed down, the second elastic member deforms, shortening the lateral distance between the two sliders, so that the two opposite sliders simultaneously squeeze the light guide plate, so that the reflection sheet and the guide plate The light board is pasted more firmly.

Description

technical field [0001] The invention relates to an assembly jig. Background technique [0002] Most light guide plates need to be pasted with a layer of reflective film on the back to improve the utilization of light. Such as figure 1 As shown, the upper surface 110 of the light guide plate 100 is provided with an asymmetrical first through hole 111 and a second through hole 112, and the upper surface 210 of the reflective sheet 200 is connected to the first through hole 111 and the second through hole. The positions corresponding to the holes 112 are respectively provided with a third through hole 211 and a fourth through hole 212 . The reflection sheet 200 has four independent flaps 220 coated with glue. There is a crease 222 at the junction of the adhesive portion and the non-adhesive portion of the upper surface 210 of the reflective sheet 200 . When assembling, place the upper surface 210 of the reflective sheet 200 upwards, then place the light guide plate 100 on t...

Problems solved by technology

[0003] Since the position of the through hole on the light guide plate is asymmetrical, the reflective sheet is often pasted in the wrong direction during the process of pasting the reflective sheet on the light guide plate. The corresponding through holes on the chip are aligned, and the reflective sheet may be poorly pasted on the light guide plate during the pasting process, which seriously affects the product yield.
