摘要
超薄显示玻璃基板是众多显示技术中不可或缺的关键基础材料,围绕超薄显示玻璃基板的物理属性和刀轮切割原理两方面进行了阐述。对超薄显示玻璃基板进行了抗弯强度测试和仿真分析,为后续切割工艺研究提供了基础数据支撑。确定了刀轮选型原则,并对比分析了台板切割和对刀切割两种切割方式。通过切割实验发现对刀切割方式的玻璃基板切割断面更为均匀稳定。此外,针对横向裂纹和纵向裂纹进行了测试和分析,并对对刀切割方式进行仿真,模拟纵向裂纹和横向裂纹,与切割实验进行了对比。更全面深入地掌握了超薄显示玻璃基板切割特性及裂纹产生机制,为超薄显示玻璃基板的切割工艺优化提供了有力依据。
Ultrathin display glass substrate is an indispensable key basic material in many display technologies.This article elaborates on the physical properties of ultra-thin display glass substrate and cutting principle of scribing wheel.Bending strength testing and simulation analysis were conducted on ultra-thin glass substrates,providing basic data support for subsequent cutting process research.The selection principle of blade wheel has been determined,and two cutting methods,namely table cutting and blade cutting,have been compared and analyzed.Through cutting experiments,it was found that the cutting section of glass substrates using the knife cutting method is more uniform and stable.In addition,tests and analyses were conducted on both transverse and longitudinal cracks,and simulations were conducted on the cutting method of the cutting tool to simulate longitudinal and transverse cracks,which were compared with cutting experiments.A more comprehensive and in-depth understanding of the cutting characteristics and crack generation mechanism of ultra-thin display glass substrates provides a powerful basis for optimizing the cutting process of ultra-thin display glass substrates.
