Abstract:In the production process of hardware, filling magnetism device is widely used in area of filling hardware magnetism, which can be conveniently used in practical application. However, the automation degree of actual device is so low at present, that the productivity is low and the labor intension is high. Further more, the width of production equipment is not reasonable, temperature is very high , the device is easily destroyed by the high heat. The smaller winding fracture restrict the ability of production. This essay designed the filling magnetism automobile system and graphic operating panel with programmable logic controller (PLC) and touch panel. Finished the designation of winding by using the theory of electromagnetism field and power electronic technology. With the debugging of program, the system could satisfy the production process. The system improved the automatism and reliability of filling magnetism device. The device had a ability of mass production. Human machine panel made operation easy and simply, it will make positive meaning to improve fill magnetism device’s automation level . The device had a profound foreground in actual application.Keywords:hardware tool;fill magnetism device;programmable logic controller;touch panel
