摘要

针对传统送料机构存在结构复杂、调节精度低、使用柔性差等缺陷，创新地提出了一种可柔性调节的混合驱动送料机构。利用封闭矢量法对混合驱动送料机构进行运动学分析，推导了牙齿轨迹与驱动电动机输出转角的函数关系；对驱动电动机输出转角进行函数规划，详细分析了转角函数中各系数对牙齿轨迹的影响，并针对几种实际缝纫场景提出了牙齿轨迹柔性调节的优化策略；分析了送料过程中牙齿所受的负载，建立了混合驱动送料机构的动力学仿真模型，对驱动电动机极限工况下的动态特性进行了分析；通过高速录像设备结合图形识别分析软件，对混合驱动送料机构的牙齿轨迹进行追踪标定，测试结果与理论计算结果相符合。混合驱动送料机构具有结构简洁、运行可靠、柔性调节等优点，深度契合当前少人化、自动化、智能化的生产需求。

Abstract

Aiming at the defects of the traditional feeding mechanism

such as complex structure

low adjustment accuracy and poor flexibility

a flexible hybrid drive feeding mechanism is proposed. In this study

the closed vector method is used to analyze the kinematics of the hybrid drive feeding mechanism

and the functional relationship between the tooth trajectory and the rotation angles of the drive motors is derived. The rotation angles of the drive motor are planned by functions

and the influence of each coefficient in the rotation angle functions on the tooth trajectory is analyzed in detail. The optimization strategies of flexible adjustment of tooth trajectory are also proposed for several practical sewing scenarios. What's more

the load on the tooth is analyzed during the feeding process

as well as the dynamic characteristics of the drive motors under the extreme working conditions by establishing the dynamic simulation model of the hybrid drive feeding mechanism. By using high-speed video equipment and graphic recognition analysis software

the tooth trajectory of the hybrid drive feeding mechanism is tracked and calibrated

and the test results are consistent with the theoretical calculation results. The hybrid drive feeding mechanism has the advantages of simple structure

reliable operation and flexible adjustment

which deeply meets the current production needs of less people

automation and intelligence.
