摘要
为提高微波炉磁控管天线焊接的自动化水平,研制了以三菱FX3U-64MT为核心控制器,触摸屏为人机界面,实现了电磁阀、气缸、电机和中频逆变电阻焊机等外部硬件控制的微波炉磁控管天线焊丝机.焊接设备由机架、传动机构和焊接电源箱、控制机构、传感器组成,控制系统具有急停、报警和温度检测等功能,可能损坏设备或造成人员伤害的动作都设计多重保护.运行结果表明:本焊丝机具有人机界面友好、操作简单和自动化水平高的特点,焊接速度达到2 s/个,不良率为0.4%.
In order to improve the automation level of the magnetron antenna welding of the microwave oven, the control system was developed for microwave oven magnetron antenna welding machine. MITSUBISHI FX3U-64MT was used as the core controller and a touch screen was used to be the man-machine interface to realize the control of the external hardware of the solenoid valve, cylinder, motor and inverter resistance welding machine. The welding equipment consisted of frame, transmission mechanism, welding power supply box, control mechanism and sensor. The control system had functions of emergency stop, warning, temperature detection and so on. The test results showed that the system had the characteristics of friendly man-machine interface, simple operation and high automation level. The welding speed reached 2 s a piece while the defect rate was 0.4%.
