[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model provides a robotic arm for multi-layer grasping of battery modules, including a base frame 1. A moving mechanism 2 is provided on the inner side of the base frame 1. A robotic arm device 4 is fixedly mounted on the upper surface of the moving mechanism 2. A suction cup mechanism 3 is fixedly mounted on one end of the robotic arm device 4. The moving mechanism 2 includes a motor 20, which is located on one side of the base frame 1. A threaded rod 25 is fixedly mounted on the output end of the motor 20. A moving block 22 is threadedly fitted on the outer side of the threaded rod 25. Moving rods 23 are fixedly mounted on both sides of the moving block 22. One end of the moving rod 23 slides against one side of the base frame 1. A mounting platform 26 is fixedly mounted on the upper surface of the moving block 22. The upper surface of the mounting platform 26 is fixedly engaged with the robotic arm device 4. During the multi-layer grasping of battery modules, the moving mechanism 2 starts to work. The motor 20 starts, and its output end drives the threaded rod 25 to rotate. Since the moving block 22 is threadedly fitted on the outer side of the threaded rod 25, the moving block 22 begins to move along the axial direction of the threaded rod 25 under the drive of the rotation of the threaded rod 25. The moving rods 23 fixed on both sides of the moving block 22 slide and engage within the moving grooves 24 on both sides of the base frame 1, serving as guides and stabilizers to ensure smooth movement of the moving block 22. As the moving block 22 moves, the mounting platform 26 fixed on its upper surface also moves synchronously. The slider 27 on the lower surface of the mounting platform 26 slides and engages on the slide rail 28 on the upper surface of the base frame 1, further ensuring the accuracy and stability of the movement. Ultimately, this drives the robotic arm device 4, which is fixedly engaged on the upper surface of the mounting platform 26, to the designated position for grasping the battery module.

[0024] Specifically, the suction cup mechanism 3 includes a mounting frame 30. One side of the mounting frame 30 is fixedly engaged with the robotic arm device 4. One side of the mounting frame 30 has multiple fixed frames 33 arranged in a rectangular array. A sliding rod 34 is provided inside the fixed frame 33, and a return spring 35 is sleeved on the outside of the sliding rod 34. A base 37 is fixedly attached to one end of the sliding rod 34, and an adsorption suction cup 36 is fixedly attached to one side of the base 37. When the robotic arm device 4 reaches the battery module position, the suction cup mechanism 3 begins to function. The robotic arm device 4 moves the suction cup mechanism 3 closer to the battery module. At this time, the adsorption suction cup 36 first contacts the surface of the battery module. Since the surface of the battery module may be uneven, the adsorption suction cup 36 slides within the fixed frame 33 via the sliding rod 34 connected to the base 37. Simultaneously, the return spring 35 is compressed, providing cushioning and adapting to different surface shapes, allowing the adsorption suction cup 36 to better conform to the surface of the battery module. Subsequently, an external air source is connected through the air pipe connection port 38 on the outside of the sliding rod 34 to evacuate the suction cup 36, creating a negative pressure inside, thereby stably adsorbing the battery module and achieving battery module gripping. When it is necessary to put the battery module down, the evacuation stops, external air enters the suction cup 36, releasing the adsorption state and completing the placement of the battery module.

[0025] Furthermore, the support frame 21 fixed on one side of the base frame 1 is fixedly engaged with the motor 20. This design can provide stable support for the motor 20, preventing the motor 20 from being displaced or damaged due to vibration or force during operation, ensuring the stable operation of the motor 20, thereby ensuring that the moving mechanism 2 can work normally and reliably, and improving the operational stability and service life of the entire robotic arm device 4.

[0026] Furthermore, the movable grooves 24 on both sides of the base frame 1 slide against one end of the movable rod 23, providing precise guidance for the movement of the movable block 22. As the movable block 22 moves along the threaded rod 25, the movable rod 23 slides within the movable grooves 24, effectively preventing the movable block 22 from rotating or shifting, ensuring that the movable block 22 always moves smoothly along a straight line. This improves the movement accuracy of the moving mechanism 2, enabling the robotic arm device 4 to accurately reach the designated position to grasp the battery module.

[0027] It is worth noting that the two symmetrically distributed slide rails 28 fixed on the upper surface of the base frame 1 slide in conjunction with the two sliders 27 on the lower surface of the mounting platform 26. This design further enhances the smoothness and precision of the movement of the mounting platform 26. The cooperation between the slide rails 28 and the sliders 27 reduces the friction during the movement of the mounting platform 26, making the movement smoother. It also effectively prevents the mounting platform 26 from shaking or deviating during movement, ensuring that the robotic arm device 4 can stably and accurately reach the target position, thus improving the accuracy and efficiency of battery module grasping.

[0028] It is worth noting that the mounting hole 31 on one side of the mounting bracket 30 is fixedly engaged with one end of the robotic arm device 4. This connection method is simple and reliable, ensuring a firm connection between the suction cup mechanism 3 and the robotic arm device 4. The design of the mounting hole 31 allows the suction cup mechanism 3 to be easily and quickly installed onto the robotic arm device 4, while also facilitating subsequent disassembly and maintenance, thus improving the assembly efficiency and maintainability of the robotic arm device 4.

[0029] It is worth mentioning that the multiple reinforcing brackets 32 fixed on one side of the mounting bracket 30 can enhance the overall structural strength of the mounting bracket 30. When the suction cup mechanism 3 grasps the battery module, it will be subjected to a certain force. The reinforcing brackets 32 can effectively disperse these forces, preventing the mounting bracket 30 from deforming or being damaged due to excessive force, ensuring the stability and reliability of the suction cup mechanism 3, and ensuring that the battery module can be grasped safely and effectively.

[0030] It is worth emphasizing that the air pipe connection port 38 on the outside of the sliding rod 34 provides convenience for connecting the suction cup 36 to an external air source. Through the air pipe connection port 38, the air pipe of the external air source can be easily connected to the sliding rod 34, thereby realizing the air extraction and inflation operations of the suction cup 36, enabling the suction cup 36 to work normally and realize the adsorption, gripping and release of the battery module.

[0031] Among them, motor 20 and robotic arm device 4 are existing technologies and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: During the multi-layer gripping of the battery module, the moving mechanism 2 starts working. The motor 20 starts, and its output end drives the threaded rod 25 to rotate. Since the moving block 22 is threaded on the outside of the threaded rod 25, the moving block 22 begins to move along the axial direction of the threaded rod 25 under the drive of the rotation of the threaded rod 25. The moving rods 23 fixed on both sides of the moving block 22 slide and fit in the moving grooves 24 on both sides of the base frame 1, playing a guiding and stabilizing role, ensuring that the moving block 22 moves smoothly. As the moving block 22 moves, the mounting platform 26 fixed on its upper surface also moves synchronously. The slider 27 on the lower surface of the mounting platform 26 slides and engages on the slide rail 28 on the upper surface of the base frame 1, further ensuring the accuracy and stability of the movement, and finally driving the robotic arm device 4 fixed on the upper surface of the mounting platform 26 to the designated position for gripping the battery module.

[0033] Once the robotic arm 4 reaches the battery module, the suction cup mechanism 3 begins to function. The robotic arm 4 moves the suction cup mechanism 3 closer to the battery module, at which point the suction cup 36 first contacts the surface of the battery module. Since the surface of the battery module may be uneven, the suction cup 36 slides within the mounting frame 33 via the sliding rod 34 connected to the base 37. Simultaneously, the return spring 35 is compressed, providing cushioning and adapting to different surface shapes, allowing the suction cup 36 to better conform to the surface of the battery module. Subsequently, an external air source is connected through the air pipe connection port 38 on the outside of the sliding rod 34, evacuating the suction cup 36 to create a negative pressure inside, thus stably adsorbing the battery module and achieving battery module gripping. When it is necessary to lower the battery module, the evacuation stops, external air enters the suction cup 36, releasing the adsorption state and completing the placement of the battery module.
