摘要
低压断路器长延时检测机械定位有不稳定和不准确的缺点,因此,文中采用机器视觉技术结合PLC,在低压断路器的长延时参数检测工位,通过步进电机和磁栅反馈相结合的方式,利用上位机图像采集,再将采集处理后的坐标等信息发送给PLC,PLC再根据接收的参数实时调整工作台的位置,保证螺钉螺母调整顺利、精确完成。与过去人工静态调整脱扣器螺钉和螺帽位置的方法相比,完成了对螺钉和螺帽的动态插补调节,实现了低压断路器长延时参数检测工位的自动化,较手工测试,生产每台断路器的时间减少30%以上。目前该系统已通过相关鉴定,运行状态良好。
The long time-delay of low-voltage circuit breaker used mchanical positioning was instability and inaccuracy,so this paper usd machine vision technology with PLC,in the long time-delay testing station,by means of stepping motor combined with magnetic gate feedback,using PC image acquisition,then the information of coordinates was sent to PLC,while PLC according to the parameters to adjust bench position to ensure completely adjust the bolt and nut.Compared to the past artificial static adjustment tripping device bolt and nut method,this design realized the low-voltage circuit breaker dynamic interpolation adjustment in the long-delay parameters testing.Now the system has reduced by 30% than the past method in testing time.At present,this system has already passed the factory＇s evaluation,and its running is in good condition.
