A Coordinated Scheduling Method for Multi-task Robots in Auto Roof Welding Production Line

Abstract

The invention relates to a multi-task robot coordination scheduling method for an automobile header welding production line. The multi-task robot coordination scheduling method comprises the followingsteps that a multi-task robot in the production line is started to send self status information and waiting vehicle model request to a PLC; if a workpiece is on an adjacent station, the vehicle modelinformation at the end of the production line is read, the multi-task robot selects a task according to a preset weight, the PLC determines whether the current task can be performed or not, if yes, and the task is executed until the task is completed; and if the adjacent station do not have a workpiece, the multi-task robot reduces task weight to wait to read the vehicle model information of a previous station, whether a workpiece is on the previous station or not is determined, if yes, and the vehicle model information of the previous station is read. The multi-task robot coordination scheduling method for the automobile header welding production line optimizes multi-task robot task scheduling without collision of multiple robots and motion equipment, production takt of the production line is effectively improved, the burden of a line body PLC is reduced, and the production efficiency of the line body is improved.

Description

technical field [0001] The invention relates to the field of dispatching of an automobile top cover welding production line, in particular to a multi-task robot coordination scheduling method for an automobile top cover welding production line. Background technique [0002] In the modern automotive body-in-white welding workshop, multiple production lines serve the main welding line, while the roof production line is generally at the end and has various processes and complex processes. In common workshop planning, because the roof line is at the end of the body-in-white production process, the space is often too tight to accommodate multiple robots, and a certain robot needs to be responsible for dozens of tasks. The increased workload in the management and scheduling of the line body wastes the computing resources of the PLC. This kind of multi-tasking robot is often one of the main reasons for the slow production tempo of the top cover line body, and even directly affects ...

[0002] In the modern automotive body-in-white welding workshop, multiple production lines serve the main welding line, while the roof production line is generally at the end and has various processes and complex processes.

In common workshop planning, because the roof line is at the end of the body-in-white production process, the space is often too tight to accommodate multiple robots, and a certain robot needs to be responsible for dozens of tasks.

The increased workload in the management and scheduling of the line body wastes the computing resources of the PLC. This type of multi-tasking robot is often one of the main reasons for the slow production of the top cover line body, and even directly affects the production efficiency of the main line.
