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. Example

[0027] Please see Figure 1-4 The present invention provides the following technical solution:

[0028] A single-cell lithium battery assembly device, comprising:

[0029] Base plate 1;

[0030] Side frame 2 is fixedly connected to the upper end of the base plate 1;

[0031] The light rod 4 is fixedly connected to the side frame 2. A connecting block 10 is connected to the light rod 4. A connecting plate 11 is fixedly connected to the side end of the connecting block 10. A telescopic rod 12 and a cylinder 15 are fixedly connected to the lower end of the connecting plate 11. A lower plate 13 is fixedly connected to the lower end of the telescopic rod 12. A spring 14 is connected between the telescopic rod 12 and the lower plate 13. A suction cup 16 is fixedly connected to the output end of the cylinder 15. A lithium battery cover 17 is connected to the lower end of the suction cup 16.

[0032] A drive mechanism is provided on the side frame 2 to enable the vertical movement of the connecting plate 11;

[0033] The pressing mechanism is set on the base plate 1 to place the individual lithium batteries during assembly.

[0034] In a specific embodiment of this utility model, the base plate 1 serves as the basic structure of the entire device, providing support and positioning functions to ensure the stability of all components. The side frame 2 supports and fixes the guide rod 4 and the drive mechanism, providing guiding support for the vertical movement of the connecting plate 11. The guide rod 4 provides a linear motion guide path for the connecting block 10, ensuring that the connecting plate 11 and its lower end components can move accurately in the vertical direction. The connecting block 10 cooperates with the guide rod 4 to achieve stable vertical movement of the connecting plate 11. The connecting plate 11 is used to install and support actuators such as the telescopic rod 12 and the cylinder 15, and realizes their action through the drive mechanism. The telescopic rod 12 is responsible for adjusting the height to ensure that the lower plate 13 can contact and properly press the lithium battery, while the spring 14 provides a cushioning effect to protect the equipment and battery from damage. The spring 14 provides an elastic connection between the telescopic rod 12 and the lower plate 13 to absorb impact force, ensure smooth pressure application, and prevent damage to the lithium battery. The cylinder 15 controls the movement of the suction cup 16, which uses suction to grip or release the lithium battery cover 17, assisting in the assembly process of the lithium battery. The lithium battery cover 17 is gripped and positioned by the suction cup 16, ready to be assembled with the lithium battery housing 21.

[0035] Please refer to the details. Figure 1-4 The drive mechanism includes a lead screw 5, a first sprocket 6, a motor 7, a second sprocket 8, and a lead screw nut 9. The lead screw 5 is rotatably connected to the side frame 2. The first sprocket 6 is fixedly connected to the upper end of the lead screw 5. The motor 7 is fixedly connected to the side end of the side frame 2. The second sprocket 8 is fixedly connected to the output end of the motor 7. The second sprocket 8 and the first sprocket 6 are rotatably connected through toothed chain meshing. The lead screw nut 9 is fixedly connected to the connecting block 10 and is connected to the lead screw 5.

[0036] In this embodiment: the lead screw 5 is rotatably connected to the side frame 2, serving as the core component for linear motion conversion. When the lead screw 5 rotates, the rotational motion is converted into linear motion through the cooperating lead screw nut 9, thereby driving the connecting block 10 and its components to move up and down. The first sprocket 6, together with the second sprocket 8, forms a transmission system through a toothed chain, responsible for transmitting the power generated by the motor 7 to the lead screw 5 to drive its rotation. The motor 7 is the power source of the entire drive mechanism. The rotational motion of the motor 7 is transmitted to the first sprocket 6 through the second sprocket 8 at its output end and the toothed chain, thereby driving the lead screw 5 to rotate. The second sprocket 8 accurately transmits the rotational motion of the motor 7 to the first sprocket 6, ensuring the efficiency and accuracy of power transmission. The lead screw nut 9 cooperates with the lead screw 5. As the lead screw 5 rotates, the lead screw nut 9 moves linearly along the lead screw 5, driving the connecting block 10 and connecting plate 11 and other components to move up and down precisely, completing the positioning and operation during the assembly of a single lithium battery.

[0037] Please refer to the details. Figure 1-4The pressing mechanism includes a frame 18, a hydraulic cylinder 19, a placement platform 20, and a lithium battery box 21. The frame 18 is bolted to the upper end of the base plate 1. The hydraulic cylinder 19 is fixedly connected to the upper end of the frame 18. The placement platform 20 is fixedly connected to the upper end of the hydraulic cylinder 19. The lithium battery box 21 is connected to the upper end of the placement platform 20. The lithium battery box 21 matches the lithium battery cover 17.

[0038] In this embodiment: the frame 18 is bolted to the upper end of the base plate 1, providing a stable support structure for the entire pressing mechanism. This not only enhances the overall rigidity of the device but also ensures the accuracy of the position of each component during the pressing process. The hydraulic cylinder 19 controls the height adjustment of the placement platform 20 to accommodate lithium battery cases 21 of different sizes and types. This ensures proper alignment and tight fit between the lithium battery case 21 and the lithium battery cover 17. The placement platform 20 serves as a working platform for supporting and positioning the lithium battery case 21. The lithium battery case 21 is prepared for assembly with the lithium battery cover 17. It matches the lithium battery cover 17, ensuring a seamless connection between the two.

[0039] Please refer to the details. Figure 1-4 The upper end of the frame 18 is provided with a rectangular groove 23, and a second connecting seat 24 is slidably connected in the rectangular groove 23. The lower end of the placement platform 20 is fixedly connected with a first connecting seat 22, and a connecting rod 25 is rotatably connected between the first connecting seat 22 and the second connecting seat 24 through a rotating shaft.

[0040] In this embodiment, the rectangular groove 23 is designed to allow the second connecting seat 24 to slide within it. This sliding connection provides the placement platform 20 with lateral or longitudinal adjustment capabilities. Furthermore, the rectangular groove 23 restricts the movement path of the second connecting seat 24, ensuring it can only move in a predetermined lateral direction, increasing operational stability. The second connecting seat 24 can slide within the rectangular groove 23 and is connected to the first connecting seat 22 via the connecting rod 25. This allows the second connecting seat 24 to adjust its position accordingly to accommodate assembly when the hydraulic cylinder 19 drives the placement platform 20 to move up and down. The first connecting seat 22 serves as the connection point between the placement platform 20 and the connecting rod 25, ensuring the connection. It is responsible for transmitting the force from the hydraulic cylinder 19, enabling the placement platform 20 to rise or fall smoothly. The connecting rod 25 is a key transmission component in the entire pressing mechanism. One end of it is rotatably connected to the first connecting seat 22 via a pivot, and the other end is similarly rotatably connected to the second connecting seat 24 via a pivot. This rotatable connection gives the connecting rod 25 a certain degree of flexibility, allowing it to automatically adjust its angle when the placement platform 20 moves up and down, maintaining optimal working condition.

[0041] Please refer to the details. Figure 1-4 A triangular plate 3 is fixedly connected between the base plate 1 and the side frame 2.

[0042] In this embodiment, the triangular plate 3 serves as a support, fixedly connected between the base plate 1 and the side frame 2, forming a stable triangular structure. According to geometric principles, a triangle is the most stable shape among all polygons and is not easily deformed. Therefore, the triangular plate 3 can significantly improve the structural rigidity and stability of the entire device, especially when subjected to large loads or external impacts, effectively preventing the side frame 2 from tilting or displacing.

[0043] Please refer to the details. Figure 1-4 A reinforcing rib 26 is fixedly connected between the connecting block 10 and the connecting plate 11.

[0044] In this embodiment, the reinforcing rib 26 is fixedly connected between the connecting block 10 and the connecting plate 11, enhancing the overall rigidity of the structure. This helps prevent unnecessary bending or deformation when the drive mechanism moves the connecting plate 11 up and down, ensuring stable movement.

[0045] The working principle and usage process of this utility model are as follows: First, prepare the lithium battery box 21 and lithium battery cover 17 to be assembled. According to the size of the lithium battery box 21, adjust the height of the placement platform 20 through the hydraulic cylinder 19 to ensure that it is in the appropriate position. Place the lithium battery box 21 on the placement platform 20, ensuring that the lithium battery box 21 is aligned with the lithium battery cover 17 to be installed later. Once the position is adjusted, start the cylinder 15 to move the suction cup 16 downward to the preset position. The suction cup 16 grabs the lithium battery cover 17, and uses the drive mechanism screw 5, first sprocket 6, motor 7, second sprocket 8, and screw screw to... The lifting and adjusting mechanism of the mother 9 is used to position the lithium battery cover 17 so that it is fully aligned with the lithium battery box 21. After confirming that everything is ready, the pressing mechanism is activated so that the hydraulic cylinder 19 moves the placement platform 20 and the lithium battery box 21 upward until the lithium battery cover 17 is firmly covering the lithium battery box 21. After the assembly is completed, check the connection between the lithium battery cover 17 and the lithium battery box 21 to ensure that the two are tightly connected without any looseness or misalignment. Turn off the vacuum source of the suction cup 16 to release the assembled lithium battery. Carefully remove the assembled lithium battery from the placement platform 20 to avoid damage.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
