Technical Field

The invention relates to the technical field of laser cutting, in particular to a glass laser cutting system.

Background

A Thin film transistor liquid crystal display (TFT-LCD) is one of the most popular liquid crystal displays, and it uses a TFT technology to improve image quality. The TFT-LCD panel can be seen as two glass substrates with a layer of liquid crystal sandwiched therebetween, the upper glass substrate is a color filter, and the lower glass substrate has a transistor embedded thereon. When the current passes through the transistor, the electric field changes to cause the liquid crystal molecules to deflect, so as to change the polarization of the light, and then the bright and dark states of the pixel are determined by utilizing the polaroid.

In the process of manufacturing the TFT-LCD, according to the requirements of production and processing, the double-layer glass needs to be cut simultaneously, and the cutter wheel cutting is widely applied due to mature and stable technology, simple process, high efficiency and lower cost of the cutter wheel equipment. However, with the technical innovation and the market change, the thickness requirement of the large-size liquid crystal display glass is thinner and thinner, the frame requirement is narrower and narrower, the traditional knife flywheel cutting process is difficult to meet the requirements, and the knife flywheel cutting has the following defects:

(1) the cutting of the cutter wheel belongs to mechanical cutting, remarkable mechanical stress is left at the edge part of the glass after the cutting, the edge strength is poor, in order to improve the edge strength of the glass and prevent the glass from further breaking after the initial cutting, the cutting surface is required to be ground or polished, then the subsequent cleaning process is carried out, and the processing procedures are multiple;

(2) the cutting precision is influenced because the cutting surface and the glass surface are not perpendicular in the cutting process of the cutter wheel;

(3) the cutting of the cutter wheel has obvious defects for ultrathin substrate materials, and in fact, the cutter wheel is very difficult to cut and process the substrate materials with the thickness less than 1mm, the substrate materials are easy to break during cutting, and the success rate is low;

(4) the cutting of the knife wheel is difficult to cut at the sealing glue position of the TFT-LCD double-layer glass, and the cutting of the knife wheel at the sealing glue position is easy to cause liquid leakage (because the sealing glue at the periphery of the LCD double-layer glass is damaged, air enters a liquid crystal display area to cause the generation of bubbles in the display area, which is called liquid leakage);

(5) In order to avoid the liquid leakage phenomenon caused by cutting of the knife wheel, the cutting line of the knife wheel is required to be outside the sealing glue, and the distance between the edge of the cut glass and the display area is more than 2mm, so that the ultra-narrow frame requirements of ultra-narrow spliced LCD splicing screens and ultra-narrow frame LCD liquid crystal display screens cannot be met;

(6) the cutting automation degree of the cutter wheel is low, and the processing efficiency is influenced.

Therefore, a new cutting method is urgently needed to improve the defects of the cutting of the knife wheel.
