Abstract

The invention discloses a mold core processing device for manufacturing a light guide plate, which relates to the technical field of light guide plate mold core manufacturing, and includes a processing table, a controller, a support arm and a telescopic rod, wherein the processing table is fixed with A controller and a support arm, in which a vertically placed lead screw is rotatably arranged, on which the lead screw is driven and connected with a nut seat, the nut seat is connected with a telescopic rod, and the telescopic rod is arranged horizontally and Attached to the outer surface of the support arm, the screw is also driven to rotate by an adjustment motor fixed on the support arm; the telescopic end of the telescopic rod is fixed with a processing head assembly, and the processing head assembly can be controlled by the telescopic rod The drive moves along the expansion and contraction direction of the expansion rod, thereby forming a microstructure on the mold core.

Description

technical field [0001] The invention relates to the technical field of manufacturing a mold core for a light guide plate, in particular to a mold core processing device for manufacturing a light guide plate. Background technique [0002] The known backlight modules can be mainly divided into direct-type and side-type backlight modules. Take the side-type backlight module as an example. The optical structure at the bottom of the light guide plate will destroy the total reflection of light and make the light leave the light guide plate, and then use the optical film set on the top to increase the brightness of the front and control the viewing angle range. In order to make the light energy of the light guide plate can be The effect of being converged to the positive light emission can be achieved by at least using the lower diffuser and matching two BEFs, but the cost of the optical film set used in this method is relatively high, and the thickness of the optical film is relat...

[0002] The known backlight modules can be mainly divided into direct-type and side-type backlight modules. Take the side-type backlight module as an example. The optical structure at the bottom of the light guide plate will destroy the total reflection of light and make the light leave the light guide plate, and then use the optical film set on the top to increase the brightness of the front and control the viewing angle range. In order to make the light energy of the light guide plate can be The effect of being converged to the positive light emission can be achieved by at least using the lower diffuser and matching two BEFs, but the cost of the optical film set used in this method is relatively high, and the thickness of the optical film is relatively thick. Therefore, it is more important to construct the optical structure at the bottom of the light guide plate, so as to improve its light output effect through the microstructure of the light guide plate; in addition, the manufacture of the light guide plate is often formed by using a precision mold core, so the processing of the mold core is more important
