摘　　要：在壳体成型系统中,激光光束的均匀性和集中性直接影响壳体加工的效率和质量。为了提高壳体固化效率和质量,采用微柱透镜和半圆柱透镜相配合的方式,对壳体固化系统所选用的3bar条半导体激光器所发射的光束进行准直和整形。从物理光学的角度对准直系统的工作原理进行了分析,搭建了仿真光路图并给出了准直后的光斑发散角和整形后的能量分布情况。设计了一款慢轴发散角小于3°、快轴发散角小于5°、光斑尺寸小于20mm×10mm的激光光源整形准直系统。有效的提高了半导体激光器的固化效率和壳体成型质量。In the shell molding system, the quality and the rate of the processing shell were affected by the laser beam＇s uniformity and concentration. In order to improve the curing efficiency and quality of the shell,the combination of micro-column lens and semi-cylindrical lens had been adopted. The beam of a semiconductor laser with three bars was shaped and collimated in the shell curing system. The working principle of direct system was analyzed from the angle of physical optics. The simulation optical path diagram was constructed and the divergence angle of light spot after collimation and the distribution of energy after shaped was given. A laser light source collimation system was completed that divergence angle of the slow axis was less than 3 degrees and the divergence angle of the fast axis was less than 5 degree. The spot size was less than 20 mm × 10 mm,the curing efficiency and shell molding quality of semiconductor laser was improved effectively.
