Automatic production line task scheduling method

Abstract

The invention relates to an automatic production line task scheduling method. With an Ethernet communication interface, network connection is formed based on a TCP / IP protocol to realize automatic control and scheduling of a numerically-controlled machine tool, an industrial robot and an AGV. A main thread is established in an upper computer; for a production task issued by a production management system, a sub thread is started to schedule the AGV to a warehouse to transport to-be-processed material plates stacked at a unified tool to a place specially for AGV parking in front of the numerically-controlled machine tool; unloading is carried out by automatic parking and the AGV returns; the sub thread commands the industrial robot to complete feeding to the numerically-controlled machine tool; after feeding by the industrial robot, the numerically-controlled machine tool is started to carry out part processing; after completion of the parts by the numerically-controlled machine tool, the industrial robot lays off the parts to an original capturing device; and after completion of all parts, the AGV is scheduled to move the processed workpieces to the warehouse.

Description

technical field [0001] The invention belongs to the field of industrial automation and relates to a task scheduling method for an automated production line. Background technique [0002] With the development of intelligent manufacturing technology, industrial robots and CNC machine tools have been widely used, and they have broad prospects in the machining industry. At present, the field of CNC machining is mostly manual operation, especially in large-scale production workshops, where there are many CNC machine tools and equipment, and the operation methods and working methods are different. At the same time, for different products, the products themselves have separate processing characteristics and processing requirements. , so it is necessary for workers to constantly familiarize themselves with and coordinate the various links of loading, processing, and unloading, which not only puts forward high requirements on the skills of workers, but also takes up a lot of labor co...

At present, the field of CNC machining is mostly manual operation, especially in large-scale production workshops, where there are many CNC machine tools and equipment, and the operation methods and working methods are different. At the same time, for different products, the products themselves have separate processing characteristics and processing requirements. , so it is necessary for workers to constantly familiarize themselves with and coordinate the various links of loading, processing, and unloading, which not only puts forward high requirements on the skills of workers, but also takes up a lot of labor costs, and the utilization rate of CNC machine tools is not high at the same time; for large Batch parts production requires manual continuous operation. The application of industrial robots will greatly improve the current situation. The degree of automation of the production line will increase, which seriously restricts the overall production efficiency.
