Development Of A Precise Automated Fiber Coil Winding Station

FOG (Fiber Optic Gyroscope) is a viable substitute to the RLG (Ring Laser Gyroscope) and has become an advanced research hotspot both in military and civilian use owing to its significant improvements in reliability, size, weight, dynamic range, cost, accuracy and so on. Research on improving FOG’s measurement accuracy is mainly concentrated on suppressing its noise and error, however, litter attention is paid to the manufacture of fiber coil-the core sensitive component of a FOG, the nonessential disfigurement in the coil is the most important factor that restricts the improvement of the FOG, the precise automated fiber coil winding station with less operator supervision and manual intervention is quite necessary, the development of a precise automated fiber coil winding station is of great significance. The main contents of each chapter are summarized as follows:In chapter 1, the principle and advantages of FOG are briefly introduced. An overview of the present research status of FOG is given in two aspects:the pattern of winding a fiber coil and the development of the winding station. The content and purpose of the research are proposed.In chapter 2, technical requirements were proposed based on the equipment of its kind domestic and overseas, the overall mechanical structure was designed based on winding process requirements, the design of principal axis system, image monitoring system, the supply unit and its positioning system, automated fiber arraying system is introduced respectively, core elements were conformed based on calculation results.In chapter 3, the overall framework of the control system was proposed, motion controller was selected as the lower computer and HMI was selected as the upper computer, the main program and user interface based on process requirements and operational habits was designed, achieved several functions including single machine commissioning, automated production, parameter configuration, fault diagnosing and power off restoration.In chapter 4, a tension control system composed of tension sensor,spring, fiber rolling and unreeling servo motor, tension controller was modeled, the state-space equation by analyzing the whole process was derived. Simulations performed with the software Simulink and self-adjusting fuzzy PID algorithm, the results show that the tension control system can meet the tension demand in different working conditions.In chapter 5, several experiments were conducted with 1# fish wire and fiber, during the testing progress, the mechanical and control system was tested and modified.In chapter 6, the content of the paper is summarized and future work is put forward.
