摘要
针对传统选择顺应性装配机器手臂(Selective Compliance Assembly Robot Arm,SCARA)机器人运动范围不足的缺点,提出一种新型平面机器人结构.首先,通过将SCARA机器人第三关节的丝杆传动结构移动到第一关节,实现机器人整体的上下平移运动,进而扩大机器人的运动空间.其次,在第一关节设置对称的支撑柱,以提升整机的刚度和运行的平稳性,保证机器人的定位精度.再次,通过设计关键部位的结构满足特殊结构的传动需求,根据结构设计和传动方案进行电机和减速机初步选型.最后,利用动力学仿真软件进行关节速度和力矩的仿真分析,验证机器人电机和减速机选型的合理性,为后续样机的生产制造提供参考.
Abstract
Aiming at the shortcoming of traditional SCARA robot,a new planar robot structure was proposed.First,by moving the screw transmission structure of the third joint of the Selective Compliance Assembly Robot Arm(SCARA)robot to the first joint,the overall up and down translation movement of the robot is realized,thus improving the movement space of the robot.Secondly,a symmetrical support column is set in the first joint to improve the stiffness of the whole machine and the smoothness of operation to ensure the positioning accuracy of the robot.Thirdly,through the design of the key parts of the structure to meet the special structure of the transmission needs,according to the structural design and transmission scheme of the motor and reducer preliminary selection.Finally,dynamic simulation software was used to simulate and analyze the joint velocity and torque,to verify the rationality of the robot motor and reducer type selection,and to provide a reference for the production of the subsequent prototype.
