| 摘 要： | 介绍了激光透射塑料焊接及全息技术的基本原理,提出了一种基于全息原理的激光同步焊接技术。为了达到塑料微小焊缝的同步焊接,采用干涉方法记录下预知焊缝特征形状,再利用衍射方法使得焊缝图形特征再现,同时激光束光斑形状被调制为与预知焊缝形状相同。利用调制完成后的激光束对塑料进行同步焊接,得到理想焊缝与预知焊缝形状相同的结果。结果表明,此项技术适用于焊缝图形小且复杂的场合。

| Abstract: | The principle of laser transmission welding of plastics and holographic technology,and laser simultaneous welding technology based on laser holographic technology were introduced.In order to achieve simultaneous welding of plastics with small weld joint,the facula figure of laser beam was modulated the same as the figure of desired weld joint using interferential method to record the figure of desired weld joint and then using diffractive method to make the figure of desired weld joint reappearance.Using th... |
