The Design Of Control System For Multi-Station Flat-Wire Winding Machine

The flat-wire winding machine is exclusively used for taking-up and secondary winding in photovoltaic solder strip production line. The winding precision is directly determined by its control system. Aimed at improving winding precision and increasing taking-up speed, multi-station flat-wire winding machine is designed in this paper.The design of control system for flat-wire winding machine can obtain high winding precision both at low-and-middle speed and at high speed, which matches the requirement of middle-end and high-end winding machine.First, according to the control requirement of the flat-wire winding machine, the two control schemes are determined, that is the dual-servo system and single closed loop system. The control principles of them are elaborated in detail.Then, through the analysis of the arranging inaccuracy under different winding speed, different frequency regulation modes are adopted to guarantee the winding precision in a wide speed rang. PID control algorithm based on position closed loop is introduced in detail and is used in frequency regulation algorithm of arranging portion to match the winding precision requirement of middle-end and high-end device.Finally,"One screen to multi-PLC"is adopted. Multi-stations are controlled and managed by one screen through writing program. According to the problems possibly arising in the debugging process, some solutions are proposed. Based on the summary of the job which has done in this paper, corrective measure is presented and the developing direction of winding machine is predicted.
