Abstract

A universal light bar assembly light guide plate re-pressing jig comprises a light guide plate, a box body, a limiting strip, a limiting area, a fixing block, an adjusting block, an adjusting groove, a sliding rail, a sliding base, a transverse air cylinder, a mounting table, a shell, a vertical air cylinder, a pressing roller, a negative pressure hole and a driving assembly. The light guide plate is placed on the fixing block and the adjusting block, and one side of the light guide plate extends into the limiting area. A negative pressure system is started to fix a light guide plate to a fixing block and an adjusting block, a transverse air cylinder pushes a shell to move forwards, a pressing roller is aligned with an overlapping area of a light bar and the light guide plate, a vertical air cylinder drives the pressing roller to press downwards in the overlapping area, a motor drives a lead screw to rotate in the positive direction and the negative direction, and the lead screw drives a sliding seat to reciprocate through a sliding block. And bonding of the light bar and the light guide plate is realized. The press-fit assembly is arranged for back-and-forth press-fit, good contact between the light bars and the light guide plate is ensured, and the activation rate of the light bar group light guide plate is increased.

Description

Technical field [0001] The present invention relates to the field of backlight modules, specifically to a general light strip assembly light guide plate repression fixture. Background [0002] Light guide plate (light guide plate) is the use of optical grade acrylic / PC plate, and then with a high-tech material with extremely high reflectivity and non-absorbing light, in the optical grade acrylic plate bottom with laser engraving, V-shaped cross grid engraving, UV screen printing technology printed with light guide point. The use of optical grade acrylic plate to absorb the light emitted from the lamp on the surface of the optical grade acrylic plate, when the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition by the front of the light guide plate. Through a variety of dense, different sizes of light guide points, can make the light guide plate uniformly emitted, in the production process of the light guide...
