Rotating Handling Robot for Efficient and Safe Logistics Transfer

1.Solution Overview​

This solution proposes a rotating handling robot for logistics transfer, aiming to address issues existing in current handling robots, such as inconvenient rotation, susceptibility of packages to slipping, and difficulty in manually moving the robot itself. Through innovative structural design, this robot integrates flexible mobility, precise rotation, and stable load-bearing functions. It can effectively improve operational efficiency in logistics transfer processes, reduce cargo damage, and enhance the user experience for operators.

​2. Technical Background and Utility Model Purpose​

​2.1 Technical Background​

With the rapid development of the logistics industry, automated equipment has gradually replaced traditional manual handling. However, some handling robots currently on the market still have significant shortcomings:

• ​Inconvenient Rotation:​​ The robot as a whole or its loading platform lacks flexible steering, making it difficult to adjust orientation in confined spaces, which affects sorting and placement efficiency.
• ​Packages Prone to Slipping:​​ The loading platform lacks effective limiting devices, causing cargo to easily slip during movement or turning, leading to increased logistics loss.
• ​Inconvenient Manual Handling:​​ The robot design does not fully consider the need for manual intervention. The body lacks easy-to-grip components, making moving and transferring the robot laborious and posing a risk of dropping.

​2.2 Utility Model Purpose​

To solve the problems mentioned above, this solution aims to provide a new logistics transfer robot with the following core objectives:

• ​Achieve Convenient Rotation:​​ Enable precise and flexible steering of the loading platform through an independent rotation module, facilitating alignment with delivery ports.
• ​Effectively Prevent Package Slipping:​​ Provide physical limits for cargo by setting retaining edges on the loading platform, ensuring stability and safety during transfer.
• ​Optimize Manual Handling Experience:​​ Design a retractable handle structure, making the robot easy to grab and carry, thereby improving operational convenience and safety.

​3. Overall Robot Structure and Component Details​

​3.1 Overall Structure Introduction​

The robot adopts a modular design, using the box (1) as the core supporting structure, integrating four functional modules: mobility, rotation, load-bearing, and operation assistance. The platform (6), as the direct load-bearing body, is connected to the box via the tray (5) and the first rotating rod (4), enabling horizontal rotation.

​3.2 Core Functional Module Details​

​3.2.1 Load-Bearing and Anti-Slip Module​

• ​Tray (5):​​ Located at the upper end of the box, connected movably to the box via the first rotating rod, serving as the direct base for the platform.
• ​Platform (6):​​ Fixed on the upper end of the tray, used for directly placing logistics packages.
• ​Retaining Edge (7):​​ Fixed around the upper end of the platform, forming a guard to effectively prevent packages from slipping during robot movement or rotation.

​3.2.2 Mobility Module​

This module employs a four-wheel drive system to ensure flexible and stable movement.

​3.2.3 Rotation Module​

• ​First Rotating Rod (4):​​ Movably connected between the box and the tray, it is the key component for transmitting rotational motion.
• ​First Rotation Motor (11):​​ Installed inside the box (Model PF60), connected to the first rotating rod, providing power for the horizontal rotation of the platform.

​3.2.4 Power and Protection Module​

• ​Second Rotation Motor (16):​​ Installed inside symmetrical housings (15) (Model PF60), providing power for the mobility wheel set. It is electrically connected to the first rotation motor, accepting unified control.
• ​Housing (15):​​ Protects the internal second rotation motor from external impact and dust.
• ​Base (17):​​ Symmetrically arranged on the upper end of the second rotation motor, providing bottom support and stability.

​3.2.5 Operation Assistance Module​

• ​Recess (8):​​ Symmetrically formed on both sides of the box, used for stowing the handle when not in use, maintaining a smooth box appearance.
• ​Handle (9):​​ Movably connected within the recess, allowing the operator to grip it easily for carrying the entire robot to the target work area.
• ​Actuating Rod (10):​​ Connects the handle to the recess, allowing the handle to be flexibly extended and retracted.

​4. Summary of Solution Advantages​

The logistics transfer robot designed in this solution offers the following significant advantages:

• ​High Efficiency:​​ The independent rotation of the loading platform reduces the need for the entire robot to turn around, making it particularly suitable for operation in narrow spaces and improving transfer efficiency.
• ​High Safety:​​ The platform retaining edge design effectively prevents package slippage, reducing the risk of cargo damage. The ergonomic handle design makes robot handling safer and less laborious.
• ​High Reliability:​​ The modular design and dedicated protective covers (protective covers, motor housings) ensure the stable operation of core components and extend the equipment's service life.
• ​Ease of Operation:​​ The movement and rotation functions are coordinately controlled by motors, making operation simple and intuitive, and reducing operational difficulty for personnel.
