Abstract

The invention relates to the technical field of laser cutting, and specifically relates to a control system based on multi-axis synchronous movement of an EtherCAT bus, for a laser cutting head. The control system based on the multi-axis synchronous movement of the EtherCAT bus, for the laser cutting head is characterized in that a signal end of an EtherCAT main station is bidirectionally connected with a motor driver for the laser cutting head; a signal output end of a PD controller is connected with a signal input end of an EtherCAT communication controller through a communication line; theEtherCAT communication controller is bidirectionally connected with a first main control board processor through a communication line; the first main control board processor is bidirectionally connected with a second main control board processor through a communication line; the second main control board processor is bidirectionally connected with a lens motor controller through ports separately;and the first main control board processor is bidirectionally connected with a sensor control board through a line port P18. Compared with the prior art, a whole laser cutting process is dynamically monitored and corresponding key process parameters are collected by virtue of an EtherCAT bus technology, any manual intervention is not needed, and a spot diameter size, a focus position and other parameters are automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of laser cutting, in particular to a control system of a laser cutting head based on EtherCAT bus multi-axis synchronous movement. Background technique [0002] Laser cutting is widely used in the processing of metal and non-metal materials. Compared with traditional processing methods, laser cutting can greatly reduce processing time, reduce processing costs and improve workpiece quality. [0003] In recent years, with the gradual popularization of laser cutting, there is an increasing demand for efficient and high-quality cutting of different types of materials. At present, this development trend urgently needs to upgrade the existing laser processing and manufacturing process and technology to achieve high-precision, high-efficiency, and high-quality cutting of different types of materials with different thicknesses. In the current laser cutting process, in order to meet the high-quality processing requi...
