and 7 of the cylinder upper and lower limit switch, and spraying is completed and the response signal SF greenware position signal ARP. Output PLC has 18 road, including: 1 ~ 9 9 station motor control signal, transfer machine 37 and 7 CD rise and fall Yan electromagnetic control signal, transfer machine 37 and 7 CD motor control signal, the clamp solenoid control signal, and greenware position signal RI, and answering spraying Ends completion signal ASF. Output control signals YO-Y17 is no direct drive AC contactor or solenoid valve, but is driven by solid state relays, so it will be PLC output interface circuit AC contactor or inductive loads such as solenoid valves to isolate, avoid the coil off current moment generated on PLC affected. The robot glazing peripheral device control system input and output points require control requirements, the system used Mitsubishi FX2N- 48MR-O01 type PLC. Its external wiring circle tSB1 1 motor start button, SG1-SG6 were 2, 3, 5, 7, 8, 9 stations on the motor trip switch. soi and SQ2 for the transfer machine 37 cylinder upper and lower limit switch, SQ3 and SQ4 to transfer machine 7, cylinder soil bit and lower limit switch.
