基于PLC的自动搬运空调机械抱手控制系统设计

Design of Mechanical Hand Automatic Holding Control System of Air-Conditioning Based on PLC

针对工厂生产线之间采用人工搬运空调存在安全隐患大、效率低等缺点,提出了一种基于PLC的自动搬运空调机械抱手的控制系统。机械抱手设计方案以三菱Q系列PLC为控制核心,设计了系统的总体控制模块,包括气动控制模块和电路控制模块。气动控制模块实现抱手夹紧和松开的功能;电路控制模块实现信号的接收和处理功能。课题组采用伺服电机实现抱手和滑板上下移动,采用步进电机实现机械抱手左右移动;根据顺序动作的控制思路,设计软件控制程序;采用GX Works2软件实现机械抱手手动、回原点、自动、自行检测、报警等控制功能。应用结果表明系统具有运行稳定可靠、方便快捷等特点,且可有效提高工厂空调的调度管理能力。本系统能改善人工搬运空调安全隐患大的状况,提高了空调的运输效率。

The factory production line adopts the manual handling of air conditioning,which exists security risks,the low efficiency of air conditioning,easily damaged and other shortcomings,a PLC based mechanical hold hand automatic handling control system of air conditioning was proposed. The design of the mechanical arms designed scheme of mechanical structure,using the MITSUBISHI Q series PLC as control core,overall design of the control module of the system,including the pneumatic control circuit module and control module,pneumatic control module with hand clamping and releasing function,the circuit controlled module to realize the function of signal receiving and processing.To realize the function of moving and hold hand skateboard servo motor was used; stepper motor to achieve the function of moving around with mechanical hands; according to the control theory of motion sequence,the control program was designed by GX Works2 software manual,mechanical hand hold back to the origin,automatic,self detection and alarm control function. The application results show that the system is not only stable,reliable,convenient and quick,but also can effectively improve the scheduling management capability of the plant air conditioner. The system can improve the safety of air handling by manual transportation,and improve the transportation efficiency of air conditioning.
