[0002] With the rapid development of artificial intelligence, automation, and information technology, the level of intelligence in last-mile logistics will continue to improve. Intelligent logistics terminals are an inevitable trend in the development of last-mile logistics, and handling robots are one of the main devices that can realize automated handling operations at intelligent logistics terminals. Handling robots can reduce the heavy physical labor of humans.

[0003] Traditional material handling robots consist of a mobile chassis, which includes a chassis body and several rollers mounted on the bottom of the chassis body. The rollers roll to move the chassis body through the warehouse, thus enabling the material handling robot to move and transfer goods within the warehouse. However, when placing multiple stacked items or relatively tall items on a traditional material handling robot, the unstable center of gravity can cause the items to become unstable, making them prone to shaking or falling.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 A handling robot for logistics warehousing includes a mobile chassis 10, a lifting assembly 20, and an auxiliary fixing assembly 30. The lifting assembly 20 is mounted and fixed on the top plane of the mobile chassis 10, and the lifting assembly 20 is provided with a movable part that can move along the height direction. The movable part of the lifting assembly 20 is detachably connected and fixed to the auxiliary fixing assembly 30, so that the movable part of the lifting assembly 20 can adjust the height position of the auxiliary fixing assembly 30. After being lifted to a position above an item placed on the mobile chassis 10, the auxiliary fixing assembly 30 can be used to auxiliaryly fix the item on top, thereby reducing the possible shaking and falling of the item during transportation.

[0023] In this embodiment, the mobile chassis 10 is a conventional structure of a material handling robot used in logistics warehousing in the prior art, and will not be described in detail here. It is understood that visual sensors and infrared sensors are installed on both sides and the front of the mobile chassis 10, so that the mobile chassis 10 can detect obstacles in the path during movement and assist it in planning its movement route.

[0024] See Figure 2The lifting assembly 20 includes a base 21, at least one column 22, a top seat 23, a lifting drive motor 24, a lead screw 25, and a lead seat 26. The base 21 is fixedly mounted on the top of the movable chassis 10. Both ends of the column 22 are fixedly connected to the base 21 and the top seat 23, respectively, so that the top seat 23 is supported and fixed at a certain height. The lifting drive motor 24 is fixedly mounted on the top of the top seat 23, and the output end of the lifting drive motor 24 is connected to the top end of the lead screw 25, allowing the output end of the lifting drive motor 24 to drive the lead screw 25 to rotate. The lead seat 26 is sleeved on the outside of the lead screw 25 and the column 22, and the lead seat 26 is threadedly connected to the lead screw 25. The lead seat 26 is slidably connected to the column 22, so that when the lead screw 25 rotates, the lead seat 26 can move vertically through the threaded engagement between the lead seat and the lead screw, and the guiding engagement of the column 22 with the lead seat 26. Thus, the lead seat 26 constitutes the movable part of the lifting assembly 20.

[0025] See Figure 3 and Figure 4The auxiliary fixing assembly 30 may include a base 31, a linear drive source 32, a top fixing part 33, two connecting arms 34, two side fixing parts 35, a rubber pad 36, a connecting frame 37, and multiple T-shaped seats 38. The connecting frame 37 is fixedly connected to the side of the base 31 facing the lifting assembly 20. The connecting frame 37 is bolted to the movable part of the lifting assembly 20, allowing the screw seat 26 to drive the connecting frame 37 and the base 31 to move vertically. The connection frame 37 can be adjusted according to the height of the item placed on the movable chassis 10, positioning the base 31 at a certain height above the item. The linear drive source 32 is mounted and fixed to the bottom of the base 31, and its output end is connected to the top of the top fixing part 33, allowing the top fixing part 33 to move and adjust its position along the height direction, thereby using the top fixing part 33 to press down on and fix the item. A rubber pad 36 is also adhered to the bottom of the top fixing part 33, covering its lower surface. The lower surface of the rubber pad 36 is provided with anti-slip texture so that when the top fixing part 33 presses down to assist in fixing the object, the rubber pad 36 can contact the object, increasing the frictional resistance between the two and reducing the impact on the object. Two connecting arms 34 are symmetrically arranged on opposite sides of the linear drive source 32, and the bottom ends of both connecting arms 34 are rotatably connected to the top fixing part 33. Two side fixing parts 35 are symmetrically arranged on opposite sides of the base 31, and the tops of both side fixing parts 35 are rotatably connected to the base 31. The top ends of the two connecting arms 34 are rotatably connected to the adjacent side fixing parts 35, so that when the top fixing part 33 moves, the two connecting arms 34 can drive the adjacent side fixing parts 35 to deflect around their connection point with the base 31 as the center of rotation. Furthermore, when the top fixing part 33 moves downward, the two side fixing parts 35 can be deflected toward the object, and the two side fixing parts 35 can block and limit the object on opposite sides, or hold the object in place. Multiple T-shaped seats 38 are respectively installed and fixed below the base 31, above the top fixing part 33, and inside the side fixing parts 35. Rotational connections between the base 31 and the side fixing parts 35, between the connecting arm 34 and the top fixing part 33, and between the connecting arm 34 and the side fixing parts 35 can all be achieved through the T-shaped seats 38 and the pins.

[0026] The system of the present invention may further include a control system for controlling the operation of the aforementioned mobile chassis, motors, and other drive sources to perform automated operations of transferring goods using the handling robot in logistics warehousing. It should be understood that the control system is not particularly limited and can be implemented using existing control technologies, which will not be elaborated upon here.

[0027] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
