机器视觉和激光切割技术在异形吸塑包装中的应用研究

Application of Machine Vision and Laser Cutting in Special-shaped Blister Packaging

为了提高吸塑成型包装生产的自动化程度,改善异形吸塑包装的裁切工艺,提出了将机器视觉和激光切割技术引入吸塑包装的生产中,采用机器视觉与激光相结合实现了对异形吸塑包装的裁剪与切割的方法。该方法采用机器视觉获得异形吸塑包装的裁切模型和裁切路径,通过智能算法辅助加工,生成辅助连接路径,应用激光切割技术实现对吸塑包装的裁切,实现吸塑包装单体的分离或切边处理。介绍了此种裁剪和切割方法的原理与应用、机器视觉的相关算法,并将该方法进行了实际应用,效果良好。

To improve the degree of automation of plastic blister packaging production, and improve cutting process of special-shaped plastic blister packaging, a method was put forward, which introduces machine vision and laser cutting technology into plastic blister packaging production, and combines machine vision with laser cutting to cut the specialshaped plastic blister packaging. The method applies machine vision technology to get the cutting mode and the cutting path of special-shaped plastic blister packaging, generates the auxiliary connection path by intelligent algorithm assisted machining, and uses laser cutting technology to cut plastic blister packaging in order to realize the separation or trimming. The principle and application of the cutting method, and correlation algorithm of machine vision was introduced. This method has been applied to practice and works well.
