Processing device for orientation layer of liquid crystal display screen

Abstract

The invention discloses a processing device for an orientation layer of a liquid crystal display screen, belongs to the technical field of electronic product processing. The processing device comprises a shell, the top of the shell is connected with an air filter through a bolt, a support plate is arranged in the shell, the top of the support plate is connected with a liquid crystal orientation plate through a sucker, and a mounting frame is arranged above the liquid crystal orientation plate. A limiting roller is rotationally connected to the mounting frame, a moving mechanism is arranged on the upper side of the mounting frame, clamping mechanisms are arranged on the left side and the right side of the liquid crystal orientation plate, a U-shaped frame is connected to the bottom of the shell through bolts, ejector rods are connected to the four corners of the bottom of the supporting plate through bolts, and the four ejector rods movably penetrate through the bottom of the shell and extend downwards. The cross-shaped plate drives the supporting plate to ascend and descend through the ejector rods, the rotation amplitude of each time is the same, the equidistant ascending and descending effect is achieved, the distance between the liquid crystal orientation plate and the limiting roller can be flexibly controlled, display screen orientation plates with different thicknesses can be conveniently clamped, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic product processing, and more specifically relates to a liquid crystal display alignment layer processing device. Background technique [0002] LCD A type of display used in digital clocks and many portable computers. LCD displays use two sheets of polarized material with a liquid crystal solution between them. Passing an electric current through the liquid rearranges the crystals so that light cannot pass through them. Thus, each crystal acts like a shutter, allowing light to pass through and blocking it. Liquid crystal displays are currently being developed towards light, thin, short, and small technology information products, and display products with a long history in computer peripherals are certainly no exception. [0003] Liquid crystal alignment technology is mainly the rubbing alignment technology widely used in the field of liquid crystal display. The rubbing alignment technology wi...
