Description

Light guide plate polishing is with examining utensil

Technical Field

The utility model belongs to the technical field of the light guide plate polishing technique and specifically relates to a light guide plate polishing is with examining utensil is related to.

Background

With the development of the liquid crystal industry, light guide plates have been widely used, and have become an indispensable part in liquid crystal modules at present, and the light guide plate mainly functions to homogenize a light source through later dot reflection after being guided in from a side by an L ED light source.

After the light guide plate is cut, the cut edges, namely four side surfaces of the light guide plate, need to be polished, and the light guide plate is not qualified due to poor polishing such as corner breakage after polishing. The existing light guide plate inspection mode is that a flashlight is manually held to irradiate a light guide plate, whether dark spots or bright spots exist on the side face of the light guide plate is observed, if yes, the light guide plate is judged to be an unqualified product, the labor intensity of the existing light guide plate inspection mode is high, the four side faces of the light guide plate need to be manually detected, the flashlight emits light, and the vision of multiple workers is damaged due to long-time work.

Therefore, there is a need to provide a new technical solution to overcome the above-mentioned drawbacks.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a light guide plate polishing that can effectively solve above-mentioned technical problem is with examining utensil.

In order to achieve the purpose of the utility model, the following technical proposal is adopted:

the utility model provides a light guide plate polishing is with examining utensil, includes the bottom plate, set firmly in the curb plate of bottom plate one side, set firmly in the diffuser plate on the curb plate, be located the curb plate with at least one light between the diffuser plate, the light with curb plate fixed connection, be provided with the cavity on the upper surface of bottom plate, the ball has been placed in the cavity, the ball exposes the cavity to what make the light guide plate level pile up places on the ball.

Further, the illuminating lamp is an L ED lamp strip.

Further: the lighting lamps are arranged at equal intervals and are 6.

Further: the concave cavities are arranged in an array.

Furthermore, 30 concave cavities are arranged in the length direction of the bottom plate, and 20 concave cavities are arranged in the width direction of the bottom plate, namely the concave cavities are arranged in an array of 30 × 20.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses light guide plate polishing is with examining utensil interferes through setting up the diffuser plate and setting up the light, makes it become the parallel light, and the workman reduces the damage that the light caused to workman's vision when looking examining in the side, and through setting up the ball, the light guide plate is placed on the ball to the workman can rotate the light guide plate, detects four faces with the completion to the light guide plate, and artifical intensity of labour is little.

The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

The following will make clear and complete description of the inspection device for polishing light guide plates according to the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 5, the light guide plate polishing inspection device of the present invention comprises a bottom plate 1, a side plate 2 fixed on one side of the bottom plate 1, a diffusion plate 3 fixed on the side plate 2 and integrally connected to the bottom plate 1 and the side plate 2, at least one illuminating lamp 4 fixed between the side plate 2 and the diffusion plate 3, wherein light emitted from the illuminating lamp 4 is interfered by the diffusion plate 3 to become parallel light, the illuminating lamp 4 is fixedly connected to the side plate 2, preferably, the side plate 2 is connected by a bolt, a cavity 5 is disposed on the upper surface of the bottom plate 1, balls 6 are disposed in the cavity 5, the balls 6 are exposed out of the cavity 5, such that the light guide plates are horizontally stacked on the balls 6, and the illuminating lamp 4 is electrically connected to a commercial power grid through an electric wire, and a switch is arranged on the wire, which is the prior art and is not described herein.

Further, the illuminating lamp 4 is an L ED lamp strip.

Further: the light 4 equidistant be provided with 6, can be for horizontal placing, also can be for vertical placing, the user selects according to actual conditions.

Further: the cavities 5 are arranged in an array, so that the balls 6 are arranged in an array, and the light guide plate can stably rotate on the balls 6.

Furthermore, 30 concave cavities 5 are arranged in the length direction of the bottom plate 1, and 20 concave cavities 5 are arranged in the width direction of the bottom plate 1, that is, the concave cavities 5 are arranged in an array of 30 × 20.
