摘　　要：目的设计一台偏口桶专用旋压盖一体机,以解决偏口桶桶口位置不确定的问题,提高上盖速度和效率。方法采用机器视觉定位系统自动定位桶口位置信息,经坐标转换后,通过TCP通讯将其传递给机器人,利用机器人的快速性及精确性,完成取盖、旋内盖及压外盖操作。结果现场搭载试验系统,对坐标变换进行数值拟合并进行旋压盖操作,定位误差基本控制在0.8 mm以内,寻口准确快速,取盖一次完成,只需对桶口定位一次,即可完成旋盖和压盖2道工序。结论该设备经实际应用,工作可靠,寻口快速,封口效率高。This work was aimed to design an eccentric bunghole cap screwing-pressing machine, in order to solve the problems of slow speed, low efficiency, and poor reliability in bunghole positioning and cap screwing-pressing. The bunghole center was automatically positioned using the robot vision positioning system. After coordinate transformation, the positioning information was transferred to the robot through TCP/IP communications, and the operations of picking up the cap, screwing the inner cap and pressing the outer cap using the rapidity and accuracy of the robot. The test system was built,numerical fitting was conducted for the coordinate transformation, and operations of screwing and pressing the cap were performed. As a result, the bunghole was positioned quickly and precisely with an positioning error of below 0.8 mm.Simultaneously, the two processes of screwing cap and pressing cap were finished at one localization. The practical application showed that the equipment was reliable, with rapid positioning ability and high sealing efficiency.
