| 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. |
