In order to reduce the high degree of dependence on human resources in the process of hamburger-making, an automatic hamburger-making machine was designed. The machine consisted of mechanical system and control system. The mechanical system included an oven, an overhead travelling crane system, a meat storage cabinet, a manipulator, a pallet trolley, an assembly line, a hamburger sauce adding mechanism and a vegetable adding mechanism. The control system included a touch screen, a communication system and a PLC (Programmable Logic Controller). The control system could regulate the mechanical system to complete a five-step task, including adding bread, adding meat, adding hamburger sauce, adding lettuce and adding bread. The automation and efficiency of hamburger-making was increased by using the automatic hamburg-making machine. The feasibility and rationality of automatic hamburg-making machine were verified by experiments.
