Carbon fiber winding tension modular control system and control method

Abstract

The invention discloses a modularized control system of carbon fiber winding tension. An unwinding module has the unwinding function; a single fiber bundle tension detection module, an active speed adjusting module, a buffering module, a fiber bundle tension detection module and a speed measuring module are sequentially arranged between the unwinding module and a core mold; a console receives tension signals of the single fiber bundle tension detection module and the fiber bundle tension detection module and speed signals detected by the speed measuring module and controls the active speed adjusting module and the unwinding module after the signals are processed, and therefore the single fiber bundle tension and the fiber bundle tension can be maintained within the preset error range; and the buffering module is used for reducing fluctuation of the fiber tension in the fiber winding process. The modularized control system has the advantages that the tension control accuracy is high, the single fiber bundle tension and the fiber bundle tension can monitored and controlled simultaneously, the response speed is high, and operation is convenient.

Description

technical field [0001] The invention belongs to the technical field of electromechanical control, and relates to a modular control system for carbon fiber winding tension. Background technique [0002] Carbon fiber winding technology is widely used in high-tech industries such as aerospace and new energy. With the continuous improvement of the process requirements of winding products, it is necessary to improve and innovate the existing winding tension control system. In the carbon fiber winding process, the fiber winding tension is a crucial process parameter, which is related to the effect of the fiber during dipping and whether it can be fully expanded on the mandrel, which directly determines the strength of the wound product. In addition, when different products are wound, the requirements for fiber tension are different, and sometimes the gap is relatively large. The traditional tension control system has a limited control range and cannot take into account both large...

Problems solved by technology

In addition, when different products are wound, the requirements for fiber tension are different, and sometimes the gap is relatively large. The traditional tension control system has a limited control range and cannot take into account both large and small tensions. At the same time, there are low control accuracy and slow response speed. question
