Winding machine with high production efficiency, product quality and other characteristics, is the key carbon fiber composite molding process equipment. In view of the demand of small batch and customized production, this paper proposes a modular design method for the winding machine structure and control system to expand the functional diversity of the winding machine. According to the demand of the product, the module configuration model is set up with the goal of the best product performance and the lowest cost. Based on the GGA, the component parts are clustered into standardized modules. Fast classification of non-dominated genetic algorithm (NSGA-II) to solve multi-objective optimization model to complete the mechanical structure of the modular configuration. The structure of distributed network controller based on field bus is proposed. The interface of controller is standardized and networked, and the controller reconfiguration is realized according to the modular configuration of mechanical structure. Based on model component object (COM) technology, the software module is designed as a COM component, and the k-nearest neighbor (k NN) method is used to classify the control modes and rebuild the COM components. The control software dynamically parses the control mode and manages the state transition of the COM components Relationship, in order to achieve the rapid reconstruction of software. Research on the structure, controller and software modular method can realize the rapid reconstruction of the winding machine and expand the function of the winding machine.
