Research And Implementation Of Motion Control System Of Automatic Adhesive Injecting Machine Based On PLC

Because of the rapid development of information industry, requirements of electronic packaging are more strictly. At present, Chinese electronic product manufacturing enterprises are mainly small and medium along the coast. So the economic numerical control system must save money, operate simply and change procedures conveniently. This paper developed a program based on PLC to improve production efficiency and reduce production cost. This paper’s main work includes the following content:(1)The paper analyses the dispensing requirements of the enterprise and learn the structures and applications of various types of motion control system. Through dissertating the kinds of control systems and the developing status of control techniques in native and foreign countries, I find out the advantages and disadvantages of kinds of motion.(2) Demonstrate the advantages of using PLC in this system, and Make deeply study of the control of stepping motor driving technique of FPX—C60T. Establish the hardware of new type open loop whose motion control system is based on PLC and the program is compiled on computer.(3) Discuss the requests of interface functions. In order to program concisely and conveniently, design the interface of control system based on touch screen. PLC can distinguish data from instructions via the interface.(4) Develop linear interpolation and arc interpolation programs according to point to point compare interpolation theory, make the system has point to point and track control functions.Objectively analyses the advantages and disadvantages of domestic and foreign molding products。Take into account of all sorts of the economy and maneuverability of motion control scheme, then determines the automatic machine control system based on PLC. According to panasonic FP series products and combining touch-screen, draws up a set of simple operation control system.After doing experiments on testbed.It prove that motion control system of the dispensing machine can meets the requirements.After further perfecting the normal operation, it can be applied in practical production.
