摘　　要：车灯透镜是汽车灯具总成中的重要聚光部件。通过分析传统车灯透镜热压成型加工中上下料过程的弊端,在对成型过程中玻璃棒料进行运动分析的基础上,提出了一种轻型、大行程的上下料机械手。利用卡当机构的特性实现机械手的大行程运动;添加曲柄滑块组合机构,进一步优化机械手的空间尺寸;利用卡当机构构件间相互运动作为组合机构动力源,有效减少驱动数量,改善了机械手的动力学性能;最后,利用虚拟样机对机械手进行运动学仿真,得出了运动轨迹,验证了该设计方案的正确性、优越性。The lamp lens is an important concentrator in the lamp assembly.The disadvantages of the traditional loading and unloading process of the hot forming process of lamp lens are analyzed.A lightweight and large-stroke loading and unloading manipulator is put forward based on the kinematic analysis of the glass rod.Introduced KaDang mechanism to realize the large stroke motion of the manipulator;added slider-crank mechanism to effectively reduce the space size of manipulator.The mutual movements among the components of KaDang mechanism is used to drive the combined mechanism,which can effectively reduce the number of drives and improve the dynamics performance of manipulator.At last,by using the virtual prototype,the kinematic simulation is carried out and the moving trail of manipulator is got,the correctness and superiority of the scheme are verified.
