摘　　要：针对电脑绣花机现有自动换底线装置灵活性差、不便于扩展,人工更换底线效率低、工作强度大等工程问题,提出一种基于总线网络且兼容绣花机主控制器的自动换底线系统模块化设计方法。创新设计了一种灵活的换旋梭装置,其内嵌控制电路板作为系统CAN节点控制单元,与换底线集中控制器构成多节点CAN总线网络拓扑,使集中控制器对各个机头换旋梭装置呈分布式控制,完成换底线动作,并详细阐述了驱动元件的控制优化方法。现场调试表明,该系统工作稳定,效率高,可扩展性强,具有较好的市场应用前景。To solve the existing engineering problems of automatic bottom thread replacing devices in computerized embroidery machines on poor flexibility,inconvenience for extension,low efficiency of manual replacement of bottom thread,high labor intensity and the like,a modular design method for an automatic bottom thread replacing system based on the bus network and compatible with the embroidery machine master controller was provided. An innovative design of a flexible bobbin replacing device is performed,and an embedded control circuit board was used as a CAN node control unit,and constituted a multi-node CAN bus network topology with the bottom thread replacement centralized controller. In this way,a distributed control over the bobbin replacing device by the centralized controller is performed to complete the replacement of bottom thread. Besides that,the optimized control method of the driving component was elaborated in detail. The field debugging results show the system is stable in operation,high in efficiency and strong in extensibility,and has good market application.
