Abstract: For the automation needs of filament threading and cutting in filament winding process, the PLC has been proposed as the core of filament threading control system. Meanwhile, the basic structure and work principles of filament threading mechanism is portrayed in detail, coupled with analyzing its working flow and allocating the I/O points. In addition, the overall design of software for control system was realized. And for the automatic mode of operation, pneumatic control, free port communication and stepper motor control were discussed in deep. Initialization of communication port and design of stepper motor speed curve were completed, and the corresponding sample program were listed.

Key words: filament threading mechanism, PLC, pneumatic control, RS485, stepper motor
