The application of AGV industrial robot creates a good environmental condition, which helps construction machinery manufacturing enterprises to carry out all-round, dynamic and fine monitoring of the overall production environment. Large heavy duty AGV is used to connect the assembly stations of the production line in series to realize the whole intelligent scheduling from online to offline. The operation of each AGV is controlled by the general control system, and the backstage division of labor is orderly and automatic coordination. The control system accepts MES production scheduling instructions and adjusts transportation routes flexibly. AGV flexible intelligent assembly line solutions help enterprises build intelligent unmanned production workshops, improve capacity efficiency and enhance core competitiveness.
