摘要
激光加工技术日益成熟,其技术的核心难点在于其振镜控制系统的设计,目前业界在激光振镜控制部分还存在一些问题。本文针对目前存在的功耗大、精度低、电路复杂等问题,研究一种基于ARM Cortex M7内核和XY2-100协议的高速振镜控制系统,有效降低控制信号传输过程中的衰减,并对激光固有的几何畸变提出一种有效的优化补偿方案,通过制作DEMO板和试验验证了整个系统的运行稳定性,在速度、精度方面比业界现有控制系统更胜一筹,满足实际加工要求,可实现每秒2万多次振镜偏转,位置控制准确,本系统具有较大应用前景。
The laser processing technology is becoming muchmaturer.Its core difficulty lies in the design of the galvanometer control system.At present,there are still some problems in the laser galvanometer control part of the industry.This paper aims at the resolution of the current problem of large power consumption,low precision,and complicated circuit.As a result,a high-speed galvanometer control system based on ARM Cortex M7core is designed.This design effectively reduces the attenuation during control signal transmission based on the XY2-100protocol and proposes an effective optimization compensation for the inherent geometric distortion of the laser.The program,through the production of DEMO plates and experiments to verify the stability of the entire system,the speed,accuracy is superior to the industry's existing control system,which meets the actual processing requirements,and can achieve more than20,000times per second galvanometer deflection,and is of accurate position control.Thus,the system has a large application prospects.
