连续 CO2激光在线膏药群孔加工系统的研究

摘要

Laser scanning and perforating systems have advantages of simple and reliable controlling structure , high perforation efficiency and good quality .Perforation systems have been widely used to perforate thin material such as paper , leather and plaster to improve the permeability and discourage the counterfeit .In order to solve the problem of expensive cost and low efficiency of the existing laser perforating equipment , an online plaster perforation system was proposed based on continuous wave CO2 laser, embedded control system and galvanometer scanning .The experiment results show that the system can adjust hole diameter from 0.2mm to 1.2mm and space between holes in the range of 4mm ~10mm at online speed of 2m/min ~12m/min.This experiment is useful to improve the efficiency of plaster laser perforation processing and expand the market of laser drilling equipment .%激光扫描打孔系统具有结构简单可靠、打孔效率高、质量好等优势，广泛用于非金属薄型材料（如纸张、皮革、膏药）加工以增强其透气度及防伪性能。为了解决现有激光打孔设备价格昂贵、加工效率低等问题，采用嵌入式控制系统与振镜扫描，设计了一套基于连续CO2激光器的在线膏药打孔设备。该膏药打孔设备在生产线2m／min～12m／min的运行速率范围，可实现通孔直径0．2 mm～1．2 mm、孔群间距4 mm～10 mm的调节功能。结果表明，该实验对膏药群孔加工效率的提高和激光打孔设备的推广是有帮助的。
