基于PLC、机器人和视觉系统的汽车轮毂全自动搬运系统设计

摘要

为研究自动化控制系统各个环节的设计方法与相互通信方式,设计了一个汽车轮毂全自动搬运系统,采用西门子S7-200 SMART进行系统逻辑控制,完成对视觉系统、ABB工业机器人机械手控制系统、汽车轮毂、光电传感器、上/下料输送线、操作按钮、人机界面、指示灯和安全门开关等各种外设的通信控制工作.经过现场调试,该汽车轮毂全自动搬运系统能对机器人夹具进行快速定位,将来料线上的轮毂较准确地搬运到下料线.同时,人机界面具有实时监视和报警功能,功能齐全,操作简单.实践证明,该系统设计能够满足设计需求,提高生产的稳定性和可靠性.%A full-automatic handing system of automobile hub is designed to study design approach and communication mode of full-automatic control system.S7-200 SMART is utilized to conduct logic control to manage integration communication of peripher -al equipments,which consists of visual system,ABB industrial robot manipulator control system ,automobile hub,photoelectric switches,load-unload conveyer line,control buttons,Human Machine Interface(HMI),indicator lights,safety gates and so on.The field debugging results show that the full-automatic handing system of automobile hub achieves rapid locating clamp of robot to precisely carry automobile hub from feeding line to blanking line.And HMI conducts the real time monitoring and alarm function ,fully-functional and reasonable designing make this system easy to operate.Practice proves that the system meets the design requirements.and improves the stability and reliability of production.
