Abstract
In recent years, the technology of special process surface treatment(electroplating) has developed rapidly in the industrial field. Especially microfracture chromalizing technique and flexible electroplating automatic line control technique became the focus of domestic and overseas researcher because of its noticeable characteristics of high efficiency, agility and high precision.
This design introduces a specific solution of microfracture chromalizing automatic line flexible control. With the framework of PT (programmable termination called touch screen) and PLC (programmable Logic controller), we build the control system, which receives and processes the signal from the electroplate equipment. At the same time, the PLC views the state information on the PT, waiting for the input order. The operator inputs the control order by PT, in order to control the states of electroplate equipment. In this way, we can realize the flexible control method. The municates with the control system by RS232 serial interface, so we can refresh the program of the system to meet different produce needs, which makes the control system more convenient for different users. The software and hardware design were carried out and applied to microfracture chromalizing automatic production line of absorber stick essfully.
Firstly, This paper discussed the theories concerning flexible electroplating automatic line. Secondly, this paper proposed solution of flexible control syst
