Research on Tension Control Technology of Insulation Belt of Automatic Transformer Winding Machine

摘要:

采用传统人工控制技术受到人为因素影响，在排线过程中出现惯性误差，导致控制效率较差，对于实现全自动变压器绕线机的高效率运行，提出了伺服自动排线控制技术的研究。根据绕线机主要设备，分析张力产生原因。使用三菱伺服驱动器，根据执行时发送的脉冲指令改变发送脉冲频率，在指定时间内使漆包线机构跟随绕线机主轴转动，由此获取排线时序图。根据时序图设计具体排线方案，通过调试确定惯性补偿系数，保证绕线能够平滑移动，改善惯性误差，实现恒定张力控制。通过调试结果可知，该技术最高控制效率可达到90%，为线圈绕制中绝缘带的张力控制和轴向紧密度提供保证。

Abstract:

The traditional manual control technology is influenced by man-made factors, and inertia error occurs in the process of wiring arrangement, resulting in poor control efficiency. For the high-efficiency operation of automatic transformer winder, The research on servo automatic cable control technology is put forward. According to the main equipment of winding machine, the cause of tension is analyzed. Using the Mitsubishi servo driver, the transmission pulse frequency is changed according to the pulse command sent during execution, and the enameled wire mechanism is rotated following the winding machine main shaft within a specified time, thereby obtaining the wiring timing chart. According to the time sequence diagram, the specific wiring arrangement scheme is designed, and the inertia compensation coefficient is determined by debugging, which ensures the smooth movement of the winding, improves the inertia error and realizes the constant tension control. The test results show that the highest control efficiency of this technology can reach 90%, which can guarantee tension control and axial tightness of coil winding.
