摘　　要：为了解决在柱面等曲面上激光打孔的问题和提高打孔成型效果,提出了一种扫描弧形柱面聚焦方案,系统将CO2激光器发射的脉冲激光调制后,入射到柱面聚焦镜压缩为线性光斑,之后经由旋转反射棱镜实现激光扫描,线性扫描光斑在经过弧形柱面聚焦镜后在曲面上聚焦为圆形光斑,实现了对光束的整形和曲面打孔。结果表明实现了在曲面上0.15mm大小的光斑,满足了包括烟支在内的工业生产需求,与传统的平面聚焦打孔方式相比本方案有更大的应用空间。To solve the problem of laser drilling on cylindrical surface and improve the effect of drilling and forming,a scanning arc cylindrical focusing scheme is proposed.After the system modulates the pulse laser emitted by the CO2 laser,the incident laser is compressed into a linear spot on the cylindrical focusing mirror,and then laser scanning is realized by rotating anti reflecting prism.The linear scanning spot is focused on the curved surface after passing through arc cylindrical focusing mirror to become a circular spot,which realizes the shaping of the beam and surface drilling.The results show that the spot of 0.15 mm in the curved surface is realized,which meets the industrial production demand including cigarette,and has a larger application space compared with the traditional plane focus drilling method.
