[0033] The present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1 The illustrated device for gluing a cylindrical battery cell S includes a frame 600, a lifting assembly 200, a limiting assembly 100, and a driving assembly 300. The lifting assembly 200 is movably connected to the frame 600 and is used to lift the battery cell S. The lifting assembly 200 can be moved from a first predetermined position to a second predetermined position. The limiting assembly 100 is arranged on the lifting assembly 200 and can move relative to the lifting assembly 200. The limiting assembly 100 is used to limit the axial movement of the battery cell S during the gluing process. The driving assembly 300 is also arranged on the frame 600 and is used to contact the side of the battery cell S to drive the battery cell S to rotate.

[0035] In actual application, when the lifting assembly 200 moves to the second predetermined position, the limiting assembly 100 holds the opposite ends of the battery cell S, and the driving assembly 300 drives the battery cell S to rotate. In this way, the battery cell S cannot move axially during the gluing process, effectively avoiding wrinkles caused by misalignment of the glue.

[0036] The following will introduce the technical details of each component one by one.

[0037] In some embodiments, as Figure 1 、 Figure 2 、 Figure 5As shown, the lifting assembly 200 includes a transverse portion 21, a longitudinal portion 22 and a supporting shaft 23. The longitudinal portions 22 are provided at the opposite ends of the transverse portion 21. The transverse portion 21 and the two longitudinal portions 22 are formed into a U-shaped structure. The end of each longitudinal portion 22 away from the transverse portion 21 is rotatably connected to the supporting shaft 23. The supporting shafts 23 on the two longitudinal portions 22 are respectively used to support the opposite ends of the battery cell S. The battery cell S is located at the opening of the above-mentioned U-shaped structure. Through the above-mentioned design, only one movable mechanism is needed to drive the U-shaped structure to lift the opposite ends of the battery cell S at the same time, thereby avoiding the uneven lifting of the opposite ends of the battery cell S due to errors of multiple lifting movable mechanisms, thereby improving the accuracy of the glue laminating process.

[0038] In some embodiments, as Figure 1 、 Figure 2 、 Figure 5 As shown, the above-mentioned limiting assembly 100 includes a first end 11 and a second end 12, which are movably disposed on the two longitudinal portions 22 and are used to respectively abut against opposite ends of the battery cell S. In actual application, when the lifting assembly 200 moves to the second predetermined position, the first end 11 rigidly abuts against the battery cell S, and the second end 12 elastically abuts against the battery cell S.

[0039] It can be understood that by rigidly abutting one end of the battery cell S and elastically abutting the other end, the battery cell S can be fixed in the axial direction of the battery cell S. If both ends are rigidly abutted, since the battery cell S itself is relatively hard, the rigid abutment of the two ends of the battery cell S can easily cause the two ends of the battery cell S to deform. If both ends of the battery cell S are elastically abutted, the battery cell S cannot be fixed well in its axial direction. Therefore, by rigidly abutting one end and elastically abutting the other end, the purpose of not easily damaging the battery cell S and fixing the battery cell S axially can be achieved, thereby ensuring the accuracy of the battery cell S during the gluing process.

[0040] In some embodiments, as Figure 5 、 Figure 6 As shown, the above-mentioned limiting assembly 100 also includes a first cylinder 13 and a second cylinder 14, wherein the telescopic end of the first cylinder 13 is connected to the first end 11, and the telescopic end of the second cylinder 14 is connected to the second end 12. The first cylinder 13 is used to push the first end 11 to rigidly abut against one end of the battery cell S, and the second cylinder 14 is used to push the second end 12 to elastically abut against the other end of the battery cell S.

[0041] In practical applications, the cylinder-driven method has a simpler structure and lower cost, which is convenient for debugging and also saves the manufacturing cost of the equipment.

[0042] In some embodiments, an elastic member is provided between the telescopic end of the second cylinder 14 and the second end 12. The elastic member may be a spring. When the second end 12 is dragged by the second cylinder 14, the second end 12 can be elastically abutted against the end of the battery cell S. While the structure is simple, the elastic abutment can well satisfy the effect of avoiding damage to the battery cell S during axial fixing of the battery cell S.

[0043] In some embodiments, as Figure 5 、 Figure 6 As shown, the above-mentioned limit assembly 100 also includes an SMC pressure reducing valve (which can reduce the air pressure in the cylinder and stabilize the air pressure inside the cylinder). The SMC pressure reducing valve is connected to the second cylinder 14 to reduce the air pressure inside the second cylinder 14, so that the telescopic end of the second cylinder 14 has the elastic effect of a spring, so that the telescopic end of the second cylinder 14 can elastically abut against the battery cell S, thereby avoiding damage to the battery cell S during the process of axially fixing the battery cell S.

[0044] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the drive assembly 300 includes a drive motor and a pressure wheel 31. The output end of the drive motor is connected to the pressure wheel 31 to drive the pressure wheel 31 to rotate. When the lifting assembly 200 moves to the second predetermined position, the pressure wheel 31 is used to press and contact the side of the battery cell S to drive the battery cell S to rotate for adhesive application. The drive motor can be a servo motor, which can very accurately control the number of rotations of the pressure wheel 31, which helps improve the accuracy of the battery cell S during the rotation and adhesive application process.

[0045] In some embodiments, as Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 As shown, the cylindrical battery cell S gluing device provided in the present application also includes a pushing component 500, the movable end of which is connected to the lifting component 200, for pushing the lifting component 200 from the first predetermined position to the second predetermined position; when the pushing component 500 pushes the lifting component 200 to lift the battery cell S and is in the second predetermined position, the pressing wheel 31 is used to press and fit tightly with the side of the battery cell S.

[0046] The above-mentioned pushing component 500 includes a torque motor 52 and a pushing device 51. The output end of the torque motor 52 is connected to the pushing device 51 to provide power for the pushing device 51. The torque motor 52 is used to drive the pushing device 51. The thrust of the pushing device 51 can be controlled by the torque motor 52. Such a design can avoid excessive thrust causing the side of the battery cell S to be overly compressed and damaged.

[0047] In some embodiments, as Figure 1 、 Figure 2 As shown, the cylindrical battery cell S gluing device provided in the present application also includes a conveying component 400, which includes a conveyor belt 41 and multiple clamping positions 42. The multiple clamping positions 42 are all arranged on the conveyor belt 41, and the clamping positions 42 are used to clamp the battery cell S.

[0048] In actual application, the conveyor belt 41 is used to transport the battery cell S to the lifting assembly 200 through the clamping position 42 for lifting and gluing. By setting multiple clamping positions 42 on the conveyor belt 41, the battery cell S can be continuously transported and glued, thereby improving the processing efficiency of the cylindrical battery cell S gluing device.
