Abstract

In this paper, we present an intelligent control strategy for automated screw fastening. In automated assembly processes, there is a large number of dedicated stations for various types/sizes of screw fastening. Problems found in current processes include cross-threading, screw jamming, slippage and the need to apply precise torque. The intelligent controller developed supervises the integrated process of an electric driver mounted on a robotic positioning system to fasten screws. The new scheme controls continuously the motion and driving stages to avoid process caused failures, to achieve a desired precise torque and to detect bad parts at early stages of the assembly. Initial results are encouraging.
螺钉自动紧固的模糊逻辑控制
本文提出了一种自动螺丝紧固的智能控制策略。在自动化装配过程中,有大量的专用工位用于各种类型/尺寸的螺钉紧固。在目前的工艺中发现的问题包括交叉螺纹,螺杆卡塞,滑移和需要施加精确的扭矩。开发的智能控制器监控安装在机器人定位系统上的电动驱动器紧固螺钉的集成过程。新方案连续控制运动和驱动阶段,以避免工艺引起的故障,实现所需的精确扭矩,并在装配的早期阶段检测出不良部件。初步结果令人鼓舞。
