Multi-task online cutting control method, system and laser cutting equipment

Abstract

An embodiment of the invention discloses a multi-task online cutting control method, a multi-task online cutting control system and laser cutting equipment, which relate to the technical field of laser cutting. The multi-task online cutting control method is characterized in that: a laser cutting main control module specifies a program path of a task program in a task program list, and the laser cutting main control module sends a program path loading completion flag bit to a PLC module after completing the loading of the program path; the PLC module loads the task program specified by means of the laser cutting main control module, and the PLC module sends a program loading completion flag bit to the laser cutting main control module after completing the loading of the task program specified by means of the laser cutting main control module; and the laser cutting main control module sends an execution flag bit to the PLC module, and the PLC module activates an NC module to control laser cutting by means of an NC_PLC interface variable. The multi-task online cutting control method disclosed by the embodiment of the invention automatically loads the next cutting task after the current cutting task is completed, realizes the uninterrupted switching of the multiple tasks, and is beneficial to improving the automation degree of the laser cutting equipment.

Description

technical field [0001] The technical solutions disclosed in the embodiments of the present invention relate to the technical field of laser cutting, in particular to a multi-task online cutting control method, system and laser cutting equipment. Background technique [0002] Laser cutting equipment for online cutting often needs to be used for multi-task cutting, such as continuous cutting of multiple workpieces with different specifications on the entire roll of material or long strip of material. [0003] The inventor found in the process of studying the present invention that the control mode of online cutting in the prior art can only perform a cycle of a single task (that is, continuously cut workpieces of the same specification), but cannot perform continuous cutting between multiple tasks. The continuous cutting between multiple tasks has a low degree of automation. Contents of the invention [0004] The technical solution disclosed in the present invention can sol...
