Abstract
This paper introduced soak spraying production processes and requirements, And improved PLC technology in on the basis of the original production line soak spraying, The original system is used in contact with the control relay, the oven door drive is a hydraulic system, the doors of change are manual, not high degree of automation. Die rails in the campaigns is operation, efficiency is low. At the same time Die link’s weaknesses is no higher precision control. From software and hardware of the system expatiated composition and functions of the PLC and introduced the principle and merit
The core of system is FX2N series, using the power of PLC, make the feeding, heating, soak spraying, drying, cooling a series of working procedure is automated. This paper adopt PLC control unit, and implement the entire control system of reliable and coordinated control, to meet the production line control system needs work。At the same time, with touch-screen technology to convenience the users to use。To solve the original control accuracy is not high, the situation of poor system stability。The design of the overall thinking is the precise control of all the motor running time to control the mold in the oven in the heating and drying time is also time to control the operation of motor control in the mold of the soak spraying, improved product Quality, reduced labor intensity, but also enhanced the production efficiency。
Keywords: soak spraying PLC touch screen product line
