目的 将传统快递物流、移动互联网和机械创新设计相结合，提出一种快递派送最后环节的载运装置应用设计方案。方法 该设计主要包括快递载运机械装置、自动控制系统和快件信息管理APP系统。快递员手持终端APP扫描快递二维码信息，并记录存放所在机械装置的具体位置；取件人收到通知取件的信息后，根据信息查找到快递位置；控制系统步进电机带动机械装置运动，将快递所在存放装置自动运至出口位置。结论 将新型机械装置与智能手机结合，实现了快递放置的整齐有序，快递派送过程中能被准确查找，降低了快递员的劳动强度，提高了物流工作效率，具有一定的应用价值。该装置的应用可以促进智慧物流的发展。

The work aims to combine the traditional express delivery, mobile internet and mechanical innovation design, and then propose a design scheme for carrier application in the last part of express delivery. The design mainly included the carrier delivery mechanism, automatic control system and an express information management APP. Firstly, the courier used a mobile phone APP to scan the express QR code, and recorded the specific location for the storage of the delivery mechanism; secondly, the customer received the message for pickup, and then the express could be easily located; finally, the stepper motor of control system drove the delivery device to move, and the express pallet was transmitted to the exit position automatically. The conclusion is that the new mechanical device in conjunction with the smart phone not only arranges the delivery in a neat and orderly way, but also reduces the labor intensity of courier to find the express quickly and accurately. It also improves the efficiency of delivery and has certain value of application. The application of this device can promote the development of intelligent logistics.
