At present,tempered glass is widely used in many fields,but its self-explosion problem has been troubling the development of the industry.The existing self-explosion defect diagnosis method can not completely solve the contradiction between the increasing use demand and the safety of tempered glass.This paper reviewed the self-explosion defect diagnosis of tempered glass.Firstly,starting from the self-explosion defect,the research status of self-explosion defect occurrence mechanism of tempered glass is introduced.Then,based on the actual application scenario,the research status of tempered glass self-explosion defect diagnosis and identification technology is introduced.Finally,based on the vigorous development of machine learning technology and computer vision technology,the development trend of self-explosion defect diagnosis and identification technology of tempered glass is prospected.The purpose is to comprehensively introduce the mechanism of self-explosion defect in tempered glass and the development status of the industry,and to provide certain reference significance for solving the problem of tempered glass self-explosion.
