Net point punching device for die core

Abstract

The invention relates to the technical field of displaying and discloses a net point punching device for a die core. The net point punching device comprises a punching mechanism, a laser distance measuring instrument, a displacement calculation controller and an upper computer. The punching mechanism and the laser distance measuring instrument are installed on an installation support, the installation base is installed on a first horizontal guide rail and can horizontally move along the first horizontal guide rail. A first driver is installed on the first horizontal guide rail and connected with the installation base through a first transmission mechanism. The displacement calculation controller is respectively and electrically connected with the laser distance measuring instrument and the upper computer. The upper computer is electrically connected with the punching mechanism and the first driver. The laser distance measuring instrument is adopted for accurately measuring the depth and bore diameter of net points, the flatness of the die core surface and the distance between the net points in real time. In the punching process, net point punching force and the moving position of the punching mechanism can be adjusted in real time, so that the bore diameter, the depth and evenness are accurately controlled, and then the depth and bore diameter tolerance of the net points is reduced.

Description

technical field [0001] The invention relates to the technical field of punching, in particular to a die core dot punching device. Background technique [0002] Thin film transistor liquid crystal display (Thin film transistor liquid crystal display, TFT-LCD for short) technology has been quite mature for applications from small-sized mobile phone screens to large-sized TV screens. [0003] The backlight module of the LCD panel is composed of light source, reflector, light guide plate, diffusion plate, prism film and optical film. One of the main technologies of its products lies in the optical design of the light guide plate, mold design and manufacturing, precision injection molding technology. The most important thing for the light guide plate is the improvement and uniform distribution of the luminance value, so the performance of the light guide plate is directly related to the yield rate of the entire backlight module. [0004] At present, the mainstream technology of...
