摘要/Abstract

摘要： 为了提高水龙头等工件的抛光效率，提高抛光精度及质量，设计了新型多工位工作岛式抛光机器人.为使该机器人结构更加紧凑，在建立抛光机器人运动学和逆运动学方程基础上，分析了该机器人的灵活加工空间，提出采用多目标的粒子群法对抛光机器人的多个布局参数进行优化分析.该方法同时对抛光机器人的2个重要布局参数进行了优化，并应用粒子群法计算该机器人抛光不同大小工件时各自由度的最大关节空间.最后通过分析抛光机器人在不同工作平面上的灵活加工点验证了优化结果的正确性.实验结果表明，优化布局后的机器人完全能满足指定工件的抛光加工需求，并有较大的加工余量，获得了较好的实验抛光效果.

Abstract: In order to improve the efficiency of the workpiece such as faucet polishing and improve the polishing precision, quality, a new multi station working island type polishing robot was designed. In order to make this robot structure more compact, based on the establishment of the polishing robot's kinematics and inverse kinematics equations, further analysis of robot flexible working space was carried out, multi-objective particle swarm optimization method was also proposed to analyze and optimize the multiple layout parameters of this robot., then the various degree of freedom joint space was obtained by particle swarm optimization method while robot polishing deferent size workpiece. Finally, the dexterous machining points of the polishing robot is analyzed, which is verified that the optimized layout parameters is suitable. Through the above analysis. It is shown that the robot with optimized layout parameters can fully meet the specified workpiece polishing requirements, and there is a large machining allowance, better experimental polishing effect was obtained finally.

Key words: multi-station working island type polishing robot, workspace analysis, layout optimization, multi-objective particle swarm optimization
