Control device of automatic sealant spraying and conveying system

The invention relates to the technical field of automobile gluing, and discloses an automatic sealant spraying and conveying system control device which comprises a conveying system, a PLC control system, a power frequency control system and a change-over switch, the PLC control system is connected with the first input end of the change-over switch, the power frequency control system is connected with the second input end of the change-over switch, and the conveying system is connected with the PLC control system. And the control system is connected with the output end of the change-over switch. When the spraying workshop works normally, the PLC system is adopted to control the conveying system, when a fault occurs, the PLC system is switched to the power frequency control system through the change-over switch, the conveying system can continue to operate, the situation that the whole workshop breaks down when the PLC system sends the fault is prevented, and therefore production can be guaranteed; when the PL
