Abstract：

In order to reduce the dynamic deformation of robot arm and end picker in hot stamping production line, ensure the feeding accuracy and speed of robot arm in hot stamping production and improve the production efficiency and yield rate of production line, the dynamic deformation of hot blank in feeding process was studied by the method of combining theoretical analysis and finite element numerical simulation from two aspects of designed structure and running speed of robot arm and end picker, and through the theoretical analysis of the model and the influencing factors of vibration, the dynamic deformation of robot arm and end picker can be reduced by decreasing the load factor, increasing the elastic modulus and the inertia moment of section. At the same time, through the comparison of the dynamic deformation of robot arm and end picker under the main rod section of hollow and cross end pickers and the analysis of the vibration deformation curves under different loading speeds, the design basis of Z-axis movement speed and Z-stroke parameters of the robot arm was given to provide technical support for the design of robot arm, end picker and hot stamping production application.
