摘要：By means of Solid Works, three-dimensional model of automated assembly system was established, and kinematic simulation based on Solid Works Motion of assembly process for relay was performed. The simulation results proved the feasibility of mechanical design. Eventually, the productivity was estimated based on simulation analysis. The mechanical design provided a solution with high reference value to practical design of automated assembly system for relay.

摘要：Palletizing robot technology has been applied more and more extensively in logistics automation *** there are some limitations in the current single-arm palletizing robot that it cannot do effective work in the process of moving back to the taking-end and the mechanical arm has so many freedoms that its control system is relatively *** on the translating cam principle,a novel palletizing robot is *** horizontal movement of the palletizing mechanical arm is controlled by changeable outer slides,and the vertical movement is controlled by partitioned up-and-down *** improve palletizing efficiency,the single palletizing mechanical arm is changed into ***,to improve its kinematic properties,the acceleration operating performance,joint driving force and palletizing trajectory are optimized through the multi-objective delaminating sequence *** to the optimization results,the 3D model of the multi-arm palletizing robot is built in Pro/E,and the kinematic simulation is *** simulation results show that the novel mechanism and optimization parameters are rational and *** novel palletizing robot has the advantages of cam mechanism,so it simplifies the driving mode of palletizing movement and can lower the requirements for controlling *** the same time,it can increase palletizing efficiency further by adding mechanical arms.
