Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: a light guide plate assembly positioning jig comprises a base 1 and a light guide plate 2 arranged on the base 1, wherein a plurality of positioning jigs are arranged on two sides of the light guide plate 2, the positioning jig comprises a fixed seat 3, a first telescopic column 5, a second telescopic column 6 and a movable plate 10, the fixed seat 3 is fixedly arranged on the base 1, and the fixed seat 3 is provided with a placing cavity, the movable plate 10 is arranged on the inner side wall of the placing cavity in a sliding way, three driving grooves 12 are arranged on the moving plate 10, one end of the second telescopic column 6 is fixedly provided with a connecting plate 7, the other end of the second telescopic column 6 penetrates through the fixed seat 3 and is fixedly connected with the pressing plate 4, the first telescopic column 5 is slidably arranged on the fixed seat 3, sliding columns 8 inserted on the driving grooves 12 are fixedly arranged on the first telescopic column 5 and the second telescopic column 6, and the lower ends of the first telescopic column 5 and the second telescopic column 6, which are positioned on the sliding column 8, are all sleeved with springs 9. Through pressing down the clamp plate 4 for the flexible post 6 extrusion spring 9 of second drives clamp plate 4 downstream, thereby makes clamp plate 4 pinpoint light guide plate 2, reduces because of the light guide plate offsets, the optics problem of production, thereby reduces manual work and material cost of maintenance.

As shown in fig. 2 and 3, the second telescopic column 6 is provided with two sets, the driving grooves 12 are composed of a trapezoidal groove at the upper end and a rectangular groove at the lower end, and positioning grooves 13 are formed at the bottoms of the two driving grooves 12 close to the second telescopic column 6. A rectangular long groove is formed in the middle of the lower end of the moving plate 10, a limiting strip 14 is arranged in the rectangular long groove in a sliding mode, the limiting strip 14 is fixedly installed on the side wall of the placing cavity, a first magnet 15 is fixedly arranged on the right side wall of the limiting strip 14, a second magnet 16 is fixedly arranged on one side, away from the limiting strip 14, of the rectangular long groove, and the first magnet 15 and the second magnet 16 are magnets of the same name. The repulsive force between the first magnet 15 and the second magnet 16 with the same name acts on the moving plate 10, so that the moving plate 10 always keeps the movement trend of moving towards the right side under the condition of no external force, the sliding column 8 on the second telescopic column 6 is stably clamped in the positioning groove 13, and the pressing effect of the pressing plate 4 on the light guide plate 2 is realized.

As shown in fig. 2 and 3, a dovetail guide 11 is fixedly connected to a side wall of the moving plate 10, and a sliding groove for accommodating the dovetail guide 11 is formed on an inner wall of the accommodating cavity.
