With the continuous development of digital technology,electronic devices such as mobile phones and tablets have become indispensable tools in production and daily life.The cover glass on such equipment is a weak link in daily use,frequent occurrence of accidental fragmentation.This is determined by the impact strength of glass materials.Researched on the falling ball impact method specified in the national standard GB/T 39814-2021,automatic control scheme for forming anti secondary impact devices,avoid secondary impact on the glass sample during the drop ball impact test,ensure the accuracy of experimental data,and reduce experimental costs.
