The invention proposes a hydropress automatic production line robot dispatching method based on minimum waiting time. The method comprises the steps of: S1) keeping a present position of a robot, and receiving request tasks; S2) calculating the number i of the received request tasks by the robot; S3) calculating a waiting time value D(n) of each request task; S4) obtaining a minimum waiting time value; S5) driving the robot to a station corresponding to a hydropress with the minimum waiting time value D(*); S6) driving the robot to a station corresponding to a hydropress, firstly giving the request task, in the minimum waiting time value D(*); S7) driving the robot a station corresponding to a request task hydropress; S8) performing a foaming task by the robot, and the robot entering the next round of dispatching after finishing the foaming task; and S9) performing a workpiece pressing task by a corresponding hydropress; and giving a request task or stopping the work after finishing the workpiece pressing task. The method, disclosed by the invention, has the advantages of high working efficiency and low energy consumption in a hydropress automatic production line.
Description
technical field [0001] The invention relates to the technical field of automatic control of hydraulic presses, in particular to a robot scheduling method for automatic production lines of hydraulic presses based on minimum waiting time. Background technique [0002] With the remarkable development of industrial automation level, the manual operation production line with harsh production environment and high labor intensity is gradually replaced by the automatic production line integrating hydraulic press and robot. In an automated production line, multiple hydraulic presses are generally equipped with one robot, and the scheduling of robots has become a key issue in technological transformation. The previous solution was to adopt the method of first request first service, only judging the sequence of request signals, without considering the waiting time of different request tasks, resulting in a large number of hydraulic machines waiting in line for a long time, resulting in...
