Abstract：

The transmission system with the industrial robot as the carrier which conveys both cold and hot metal sheets is one of the key links of the automatic production line for high strength steel hot stamping. In order to minimize the heat lose of the hot sheet during transmission, the rapidity and stability of the robots movement must be guaranteed. With the high strength steel hot stamping production line as the research background, the kinematics model of the joint industrial robot with six degrees of freedom was set up. On the basis of analyzing the motion characteristics, a kind of optimized transmission path was found out. After comparing with the former scheme by both the simulation results and the test results, the optimized scheme proved its superiority and adaptability by reducing the transmission time from 2.7 s to 1.8 s and reducing the acceleration simultaneously.
