目的 研究一种能够提高快递包装效率的辅助夹持装置。方法 通过研究快递包装的流程及方法，利用所设计出的提升机构、夹持机构、旋转封胶机构来实现快递辅助包装的工作，利用Ansys和Matlab进行仿真试验，确定机构可行性之后，制作出物理样机，并进行实地试验。结果 结果显示，包装成功率在95.3%左右，满足了辅助人工包装快递的实际需求；机器包装连续率在96.1%以上，装置在工作时具有较高的可靠性；连续对多个纸箱进行包装的工作情况下，平均包装每个纸箱耗时13 s左右，缩短人工包装所需时间的55.3%以上。结论 快递夹持辅助包装机能够辅助工作人员实现快递包装的夹持工作，能够减轻快递包装人员的劳动强度，提高工作效率。

The work aims to study an auxiliary clamping device that can improve the efficiency of express packaging. By researching the process and method of express packaging, the designed lifting mechanism, clamping mechanism and rotating sealing mechanism were used to realize the work of express auxiliary packaging. Ansys and Matlab were applied to carry out simulation experiment to determine the feasibility of the mechanisms, make the physical prototype and carry out the field test. The results showed that, the packaging success rate was about 95.3%, which satisfied the actual demand of assisting the manual express packaging. The continuous rate of machine packaging was above 96.1%, and the working reliability of the device was high. Under the working condition of continuously packaging multiple cartons, the average packaging time for each carton was about 13 s, which reduced the time required for manual packaging by more than 55.3%. The express clamping auxiliary packaging machine is able to assist the staff in realizing the clamping work of express packaging, which can reduce the labor intensity of express packaging personnel and improve the work efficiency.
