[0002] Intelligent logistics utilizes advanced Internet of Things technologies such as barcodes, radio frequency identification technologies, sensors, and global positioning systems. Through information processing and network communication technology platforms, it is widely applied to basic activity links in the logistics industry, such as transportation, warehousing, distribution, packaging, and loading and unloading, to achieve automated operation and high-efficiency optimized management of the goods transportation process, improve the service level of the logistics industry, reduce costs, and reduce the consumption of natural resources and social resources. The Internet of Things provides a good platform for the logistics industry to combine traditional logistics technologies with intelligent system operation management, and thus can better and faster realize the informationization, intelligence, automation, transparency, and systematic operation mode of intelligent logistics. In the process of implementation, intelligent logistics emphasizes the wisdom of logistics process data, network collaboration, and decision-making wisdom. Automatic bin handling is an important link in the intelligent logistics system.

[0003] A lifting device of a bin robot with the publication number of CN221116876U includes a frame body. Column assemblies are arranged on both sides of the frame body, and a plurality of reinforcing cross bars are connected between the column assemblies. The column assembly includes a vertically arranged column. Belt pulley fixing seats are arranged at both the upper and lower ends of the column.
