摘　　要：随着国内外注塑行业的快速发展,传统的人工上下料已经无法满足工业化的需求,注塑机械手解决了该问题。根据卧式注塑机上下料工作的特点,设计了一台注塑专用机械手,主要由底座、横梁机构、悬臂机构、主副臂机构、手部机构等部件组成,可以实现3个方向的运动。将绘制的注塑机械手三维模型简化后导入ADAMS中,对其进行运动学仿真分析,得到了机械手完成的各运动的位移、速度等曲线,3个方向的位移和速度均是同步变化的,速度曲线均平滑无尖角,因此,机械手在作各项运动时,比较平稳,没有出现明显的振动,满足注塑机械手的工作要求,验证了设计的合理性,并为注塑机械手的运动控制提供了理论支持。With the rapid development of injection molding industry at home and abroad,the traditional manual loading and unloading had not been able to meet the demand,injection manipulator came into being.According to the characteristics of horizontal injection molding machine,a special manipulator for injection molding was designed,it was mainly composed of the base,the beam mechanism,the cantilever mechanism,the main and secondary arm mechanism,the hand mechanism and other components,and it could realize the movement in three directions.The drawn 3d model of the injection molding manipulator was simplified and imported into ADAMS software.The kinematics simulation analysis of the injection molding manipulator was conducted,and the displacement and velocity curves of each movement of the manipulator were obtained,the displacement and velocity in the three directions all changed synchronously,and the velocity curves were smooth without sharp angles.This meant that the manipulator was relatively stable when doing various movements,there was no obvious vibration which met the working requirements of injection molding manipulator.The rationality of the design was verified and the theoretical support was provided for the motion control of the injection molding manipulator.
