摘要/Abstract

摘要： 利用532 nm纳秒激光通过自下而上螺旋线的扫描方式可实现浮法玻璃高效切孔,但纳秒激光作用于玻璃时的明显热效应将使玻璃在激光切孔过程中产生崩边、孔壁表面白斑、表面微观裂纹和凹坑等缺陷行为。围绕该问题,本文通过单因素试验方法,探究了532 nm纳秒激光切孔缺陷行为。结果表明,激光脉冲频率是影响缺陷形态的关键因素,不合适的脉冲频率与脉冲能量会严重增大玻璃孔边缘崩边情况以及孔壁表面粗糙度,同时产生不均匀区域性白斑;增加扫描速度会降低孔壁表面粗糙度;较小螺旋线重叠率会导致玻璃孔壁产生波纹状表面形貌;孔壁质量较差时微观裂纹凹坑更加明显。

Abstract: Efficient cutting of float glass can be achieved by using 532 nm nanosecond laser with the bottom-up spiral scanning method. Due to the obvious thermal effect when the nanosecond laser acts on the glass, it will cause glass edge chipping, white spots on the side wall surface, surface micro cracks and voids and other defect behaviors. Focusing on this problem, the single-factor experimental method was used to explore 532 nm laser hole cutting defect behavior. The results show that the laser pulse frequency is the key factor affecting the defect shape. Improper pulse frequency and pulse energy will seriously increase the glass edge chipping and the surface roughness of hole wall, and also produce uneven regional white spots. Increasing the scanning speed will reduce the surface roughness of hole wall. Smaller spiral overlap rate will cause the corrugated surface morphology of glass hole wall. When the hole wall quality is poor, the micro cracks and voids are more obvious.

Key words: 532 nm nanosecond laser, float glass, surface topography, hole cutting defect, chipping, surface roughness
