[0027] In order to make the utility model purpose, features, and advantages of the present utility model more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be an intermediate component present at the same time.

[0029] The following further illustrates the technical solutions of the present utility model with reference to the accompanying drawings and through specific embodiments.

[0030] As Figures 1 to 3 shown, the embodiment of the present utility model provides a battery sealing mechanism for preventing liquid spillage, including a rotating column 1, a first gear disk 2, a sealing assembly 3, a clamping seat 4, a follower lifting assembly 5, an annular track 6, and an upward movement limiting assembly 7;

[0031] The first gear disk 2 is arranged at the bottom of the rotating column 1, and the first gear disk 2 is used for meshing connection with an external driving device to drive the rotating column 1 to rotate; the annular track 6 is connected to the bottom of the rotating column 1 through a first slewing bearing. The annular track 6 includes an integrally formed first track portion 61 and a second track portion 62. The first track portion 61 is located in the lower region of the second track portion 62, and a slope difference is formed between the first track portion 61 and the second track portion 62;

[0032] A plurality of the follower lifting components 5 are arranged in the lower region of the rotating column 1. The follower lifting component 5 includes a first fixed seat 51, a slide rail 52, a lifting seat 53, a spring member 54, a first pulley 55 and a second pulley 56. The first fixed seat 51 is connected to the rotating column 1. The slide rail 52 is vertically arranged on the first fixed seat 51, and the slide rail 52 is connected to the lifting seat 53 through a slider. The lifting seat 53 can move along the length direction of the slide rail 52. The bottom of the lifting seat 53 is connected to the first pulley 55 through the spring member 54. The first pulley 55 abuts against the annular track 6. The first pulley 55 is used to apply an upward moving thrust to the lifting seat 53 as the rotating column 1 rotates. In this embodiment, due to the slope difference on the annular track 6, when the rotating column 1 rotates, the movement of the first pulley 55 on the annular track 6 will be affected by the slope difference, resulting in the lifting movement of the first pulley 55. Specifically, when the first pulley 55 moves from the first track portion 61 with a lower slope to the second track portion 62 with a higher slope, the first pulley 55 will move upward, and drive the lifting seat 53 to move upward through the spring member 54. The spring member 54 can provide a resilience to the lifting seat 53, so that the lifting seat 53 can automatically return to the initial position when the first pulley 55 moves along the first track portion 61 with a lower slope. In addition, during the lifting process, the lifting movement of the first pulley 55 caused by the slope difference will generate a certain impact force, and the spring member 54 can absorb and buffer these impact forces, making the moving process smoother.

[0033] The second pulley 56 is arranged on the back of the lifting seat 53, and the second pulley 56 is located above the first pulley 55. The upward movement limiting component 7 is arranged at the bottom of the first fixed seat 51. The upward movement limiting component 7 is located above the second pulley 56. The upward movement limiting component 7 is used to abut against the second pulley 56 when the lifting seat 53 rises, so as to limit the upward travel of the lifting seat 53, prevent the impact force released by the spring member 54 from being too large to oscillate the electrolyte inside the battery and cause liquid leakage and alkali creep, and at the same time avoid damaging the sealing ring of the battery, effectively improving the sealing quality of the battery.

[0034] The clamping seat 4 is arranged on the top of the lifting seat 53. An arc-shaped clamping opening 40 for clamping the battery is arranged on the clamping seat 4. The sealing component 3 is arranged on the rotating column 1 above the clamping seat 4. The sealing component 3 is used to seal the battery on the clamping seat 4. The arc-shaped clamping opening 40 on the clamping seat 4 can firmly clamp the battery, prevent the battery from moving or deviating during the sealing process, and facilitate the accurate sealing operation of the sealing component 3. The sealing component 3 can apply a certain pressure to the battery on the clamping seat 4, so that the sealing part of the battery is tightly combined, ensuring the firmness and tightness of the seal.

[0035] As Figure 2 and Figure 3 shown, further, the upward movement limiting component 7 includes a connecting plate 71 and a limiting plate 72. The limiting plate 72 is arranged on the top of the connecting plate 711, and the limiting plate 72 is located above the second pulley 56. When the lifting seat 53 rises to a predetermined height, the second pulley 56 will contact the limiting plate 72 to form a physical limit to prevent the lifting seat 53 from continuing to rise. Moreover, the limiting plate 72 can absorb part of the impact force during the lifting process, prevent the force released by the spring member 54 from impacting the product sealing ring, and prevent the impact force from oscillating the internal electrolyte of the product, resulting in product alkali leakage.

[0036] As Figure 1 shown, further, it also includes a second gear disc 9. The second gear disc 9 is rotatably connected to the top of the rotating column 1 through a second slewing bearing. The second gear disc 9 can rotate independently relative to the rotating column 1 under the driving action of an external power device.

[0037] As Figure 1 shown, further, the sealing component 3 includes a third gear disc 31, a second fixed seat 32, a rotating shaft 33, and a sealing sleeve 34. The second fixed seat 32 is arranged on the rotating column 1. The rotating shaft 33 is rotatably connected inside the second fixed seat 32. The third gear disc 31 is connected to the top of the rotating shaft 33, and the third gear disc 31 is meshed and connected with the second gear disc 9. The third gear disc 31 is used to drive the rotating shaft 33 to rotate under the rotation of the second gear disc 9. The sealing sleeve 34 is arranged at the bottom of the rotating shaft 33. When the second gear disc 9 rotates, it can drive the third gear disc 31 to rotate. Since the rotating shaft 33 is connected to the third gear disc 31, the sealing sleeve 34 connected to the rotating shaft 33 is driven to rotate synchronously. With such a setting, the sealing sleeve 34 can be aligned with the sealing position of the battery for sealing operation.

[0038] As Figure 2 shown, further, a circular groove 530 is arranged on the top of the lifting seat 53. The circular groove 530 is used for positioning and placing the battery. The setting of the circular groove 530 can stably accommodate the cylindrical battery, prevent the battery from sliding or tilting during the lifting process, and ensure the smooth progress of the sealing process.

[0039] As Figure 1 and Figure 2As shown in the figure, further, an elastic limit component 8 is further included. The elastic limit component 8 includes a mounting seat 81, a first pull rod 82, a tension spring 83 and a second pull rod 84. The mounting seat 81 is arranged on the side wall of the first fixed seat 51. The first pull rod 82 is arranged on the mounting seat 81. The second pull rod 84 is arranged on the lifting seat 53. The first pull rod 82 and the second pull rod 84 are connected by the tension spring 83. The tension spring 83 is used to apply a downward retracting pulling force to the lifting seat 53. When the lifting seat 53 is lifting, the tension spring 83 in the elastic limit component 8 can absorb and buffer the impact force and vibration of the lifting seat 53, reduce the direct impact on the battery, effectively prevent the oscillation and liquid spilling of the electrolyte inside the battery, and improve the smoothness of the sealing process.

[0040] Further, the wheel width of the first pulley 55 is equal to the width of the annular track 6. With such a setting, the contact area between the first pulley 55 and the annular track 6 can be increased, thereby enhancing the stability of the first pulley 55 on the annular track 6 and preventing the first pulley 55 from shifting or skidding.

[0041] In the present utility model, due to the slope difference on the annular track 6, when the rotating column 1 rotates, the movement of the first pulley 55 of the follower lifting component 5 on the annular track 6 will be affected by the slope difference, prompting the first pulley 55 to apply an upward moving thrust to the lifting seat 53, so that the battery on the clamping seat 4 can be sealed by the sealing component 3. The second pulley 56 is arranged on the back of the lifting seat 53, and the upward movement limiting component 7 is located above the second pulley 56. The upward movement limiting component 7 can limit the maximum upward travel of the lifting seat 53, prevent the impact force released by the spring member 54 from being too large to oscillate the electrolyte inside the battery and cause liquid spilling and alkali creeping, and at the same time avoid damaging the sealing ring of the battery, effectively improving the sealing quality of the battery.

[0042] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
