摘要 从避免芯片操作机器人与外界环境碰撞的角度进行了安全性设计研究。设计了一种能够感知碰撞发生信号,基于继电器和电磁制动器实现机器人保护的碰撞保护装置,计算分析了本装置对芯片操作机器人定位精度的影响。实验表明,此装置能够精密控制前冲惯性位移<1 mm,适应性强,不影响操作机器人定位精度,有利于提高微流控芯片自动化制造系统的安全性和自动化水平。 To ensure safety for a handling robot used in polymer microfluidic chip, a reliability design was presented by researching the collision protection between handling robot and objects around. A collision protection system mainly based on a relay and a electromagnetic brake was designed to distin guish collision signal and to complete protection for handling robot immediately. The position precision of the handling robot caused by the collision protection system was calculated and analyzed. The experimental results indicate that the inertial displacement can be controlled to less than 1 mm and the collision protection system has no affect on position precision. These results means that designed system is beneficial to reliability and automation of the microfluidic chip automated fabrication system.
