This article describes the mechanical structure design method of the stacking-destacking robot and puts forward part kinematics analysis. In accordance with the actual technology requirement of modern brick kiln companies in logistics automation industry, a universal stacking-destacking robot is designed based on the functional requirement. And depending on the actual production requirements of the robot, it is designed to a kind of five-dof cylindrical coordinate one. This thesis focuses on the design and analysis of the mechanical structure of the robot. And according to the production requirements, some important components are selected. Finally, the kinematics analysis of the robot was brought forward and they are verified by experiments. The results show that this robot we designed can completely satisfy the technical requirements of the work in brick kilns destacking.
