摘要
针对集装箱外焊缝自动抛丸清理设备,设计了检测控制系统。该系统利用PLC作为控制核心,采用激光测距传感器来检测垂直焊缝。传感器被固定在生产线的一侧,集装箱在生产线上流水性通过。当焊缝经过激光传感器前时,激光传感器会检测到距离突变,通过算法可判断出焊缝经过的时刻。在此基础上,PLC可以控制抛头,使磨料准确地抛打清理焊缝。
A measurement and control system is designed for impact cleaning equipment of container. In this system ,the laser distant sensor is used to measure the vertical welding line and the PLC is used to control the system. The equipment is pegged on the side of product line, and the container is being on-line. The distance break can be measured by the laser distance sensor when the welding line passing and the passing time can be calculated using the arithmetic. According to the passing time, the PLC controls the impact to clean the welding line.
