机器人冲压生产线的仿真与优化

Simulation and optimization of robot stamping production line

为了对机器人冲压生产线方案进行有效验证及优化,以发动机罩壳冲压生产线为研究对象,选取六轴工业机器人为移料载体,设计出两种生产线整体布局方式,综合分析选择最优整体布局规划,并对生产线中的设备进行三维建模。在FANUC ROBOGUIDE软件中按布局规划方案,建立实际冲压生产线模型和完成对机器人的路径规划,最终在软件中进行仿真运行,实现了机器人取/放物料、压机作业以及物料变形的动态仿真。通过分析仿真结果,进一步优化了机器人作业路径和生产线节拍,使机器人作业路径更加柔性、简洁,整条生产线更加高效、无干涉运行,生产节拍由原来的15.42 s/件,提高到11.61 s/件。研究结果充分证明了优化方法的可行性和实用性。

On the engine cover stamping production line,two kinds of overall layouts for production lines were designed by selecting six-axis industrial robots as carriers so as to realize effective verification and optimization for the solutions of robot stamping production line.Then,a comprehensive analysis was made to select the best overall layout planning,and the 3D model was built for the equipment on the production line. Furthermore,the layout planning solution was realized by FANUC ROBOGUIDE software,and the actual stamping production line models were established as well as the robot path planning was completed. Finally,robots taking or releasing materials,operating the press work and dynamic simulations of material deformation were carried out by software. Based on the analysis of simulation results,the robotic operation path and production step were optimized further to make robot operation path more flexible,simple and efficient moving without any interference. In addition,the production step increased to 11. 61 s per piece from original 15. 42 s per piece.The research results prove the feasibility and practicability of the optimized method.
