摘要
针对滚镀过程中电流密度随机多变的特点,设计出一套能够在线监控滚镀过程中电流密度的闭环系统。介绍了该系统的架构,并详细阐述了上位机、高频电源模块和电流密度采集设备的设计思路。设计的闭环系统借助磁敏感传感器采集并经换算获取滚镀过程中的实时电流密度,并将其反馈至控制芯片,通过控制高频电源模块的输出,实现对滚镀过程中电流密度的在线监控。
Barrel plating current density vary irregularly and randomly. According to these characteristics, a closed-loop online monitoring system for barrel plating current density was designed. The system architecture was introduced, and the design idea of each component, that is, host computer, high frequency power module and current density acquisition equipment, was elaborated. Based on the designed closed-loop system, real-time current density was acquisited with magnetic sensitive sensor, and then feedback to control chip. Through controlling the output of high frequency power module, online monitoring of barrel plating current density was realized.
