Cutting device and cutting method

Abstract

The invention provides a cutting device and a cutting method. The cutting device comprises a machine table, a slide rail unit disposed on the machine table and parallel to a horizontal plane, a movement unit connected to the slide rail unit and a cutting unit connected to the movement unit; the slide rail unit includes a first sliding rail and a second sliding rail which are parallel to each other, the first sliding rail and the second sliding rail are arranged in a horizontal direction, and when the movement unit slides on the first sliding rail and the second sliding rail, and the bottoms ofthe first sliding rail and the second sliding rail are supported by the machine table, which can prevent the first sliding rail and the second sliding rail from being pressed by the one-side force, thereby prolonging the service life of the slide rail unit.

Description

technical field [0001] The invention relates to the technical field of cutting, in particular to a cutting device and a cutting method. Background technique [0002] Thin Film Transistor (TFT) is the main driving element in current Liquid Crystal Display (LCD) and Active Matrix Organic Light-Emitting Diode (AMOLED). It is related to the display performance of the flat panel display device. [0003] Most of the liquid crystal displays currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to pour liquid crystal molecules between the thin film transistor array substrate (ThinFilm Transistor Array Substrate, TFT Array Substrate) and the color filter (ColorFilter, CF) substrate, and apply pixel voltage on the two substrates respectively. and the common voltage, through the electric field formed between the pixel voltage and the common voltag...

AI Technical Summary

Problems solved by technology

The cutting part of the cutting machine in the prior art is mainly composed of four parts: cutting head, slide rail, optical ruler and linear motor. The linear motor provides power to drive the entire cutting head to run on the slide rail, and the optical ruler is set above the slide rail. , to ensure cutting accuracy, but the existing cutting head, slide rail, optical scale and linear motor are set on the same vertical plane, and all are located on the side of the machine table, resulting in one-sided force on the slide rail, which will cause long-term Serious wear and tear on the slide rail will reduce the service life. In addition, the distance between the optical ruler and the slide rail is relatively close, and the oil on the slide rail and the glass powder produced during the cutting process will pollute the optical ruler, resulting in abnormal accuracy.
