Detailed Implementation

[0035] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] like Figures 1 to 4As shown, a battery sealing mechanism provided in one embodiment of the present invention includes a support base 1, a lifting drive assembly 2, an upper mold assembly 3, and a lower mold assembly 4;

[0037] The upper mold assembly 3 includes an upper plate 31, an upper mold 32, a first wedge 33, and a second wedge 34. The upper mold 32, the first wedge 33, and the second wedge 34 are all mounted on the upper plate 31. The output end of the lifting drive assembly 2 is connected to the upper plate 31.

[0038] The lower mold assembly 4 includes a first lower plate 41, a second lower plate 42, a first connecting piece 43, a second connecting piece 44, a first lower mold half 45, and a second lower mold half 47; the first connecting piece 43 and the second lower mold half 46 are both mounted on the first lower plate 41, and the second connecting piece 44 and the second lower mold half 46 are both mounted on the second lower mold half 47; the first lower plate 41 and the second lower plate 42 are both slidably mounted on the support base 1;

[0039] The lifting drive assembly 2 is used to drive the upper plate 31 to move along a first direction. The first wedge 33 is used to drive the first lower plate 41 to move along a second direction through the first docking member 43. The second wedge 34 is used to drive the second lower plate 42 to move along a second direction through the second docking member 44. The first lower mold 45 and the second lower mold 46 are combined to clamp the battery case 101. The upper mold 32 covers the first lower mold 45 and the second lower mold 46 to drive the upper part of the battery case 101 to bend inward and wrap around the positive electrode cap 102. The first direction is perpendicular to the second direction.

[0040] The lifting drive assembly 2 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, linear motors, and lead screw and nut assemblies; the first wedge 33, the second wedge 34, and the upper mold 32 are all mounted above the upper plate 31. The first docking member 43 is mounted above the first lower plate 41, and the second docking member 44 is mounted below the second lower plate 42; the first lower mold is mounted on the side of the first lower plate 41 facing the second lower plate 42, and the second lower half mold is mounted on the side of the second lower plate 42 facing the first lower plate 41.

[0041] Specifically, before the battery sealing mechanism seals the battery, the positive electrode cap 102 is located inside the battery casing 101, and the wall thickness of the upper part of the battery casing 101 is less than that of the lower part. The lifting drive assembly 2 drives the upper plate 31 to descend in a first direction. The first wedge 33 on the upper plate 31 abuts against the first docking member 43 and drives the first lower plate 41 to move in a second direction. The second wedge 34 on the upper plate 31 abuts against the second docking member 44 and drives the second lower plate 42 to move in a second direction. The first lower mold 45 and the second lower mold 46 merge to clamp the battery casing 101 from opposite sides. The upper plate 31 continues to move downward, and the upper mold 32 covers the merged first lower mold 45 and second lower mold 46. The downward pressure of the upper mold 32 causes the upper part of the battery casing 101 to bend inward and wrap around the positive electrode cap 102, thereby achieving a sealed connection between the battery casing 101 and the positive electrode cap 102.

[0042] In this invention, the upper mold assembly 3 can not only drive the lower mold assembly 4 to close the mold through the first wedge 33 and the second wedge 34, but also cover the lower mold assembly 4 to drive the upper part of the battery shell 101 to bend inward and wrap around the battery cap 102. The battery sealing mechanism has a simple structure, low manufacturing cost, high stability, and ensures the sealing quality of the battery.

[0043] In one embodiment, such as Figure 3 and Figure 4 As shown, the first lower mold 45 and the second lower mold 46 both protrude toward the upper mold 32; the first lower mold 45 is provided with a first semi-groove 451 adapted to the battery case 101, and the second lower mold 46 is provided with a second semi-groove 461 adapted to the battery case 101.

[0044] The upper mold 32 is provided with a molding groove 321, and the upper mold 32 covers the first lower mold 45 and the second lower mold 46 through the molding groove 321.

[0045] The molding groove 321 is adapted to the first lower mold 45 and the second lower mold 46, and the opening of the molding groove 321 faces downward.

[0046] Specifically, when the first lower mold half 45 and the second lower mold half 46 are combined, the first semi-groove 451 and the second semi-groove 461 surround the battery casing 101. Both the first lower mold half 45 and the second lower mold half 46 protrude towards the upper mold 32, allowing the upper mold 32 to cover them from above. In this embodiment, the docking stability between the upper mold assembly 3 and the lower mold assembly 4 is high.

[0047] In one embodiment, such as Figure 2 and Figure 3 As shown, the upper mold assembly 3 also includes a first guide rod 35, a second guide rod 36, a first elastic element (not shown in the figure), and a second elastic element (not shown in the figure); the upper plate 31 is also provided with a first guide hole and a second guide hole;

[0048] One end of the first guide rod 35 is connected to the first wedge 33, and the other end of the first guide rod 35 is slidably inserted into the first guide hole. The opposite ends of the first elastic member abut against the first wedge 33 and the upper plate 31, respectively.

[0049] One end of the second guide rod 36 is connected to the second wedge 34, and the other end of the second guide rod 36 is slidably inserted into the second guide hole. The two opposite ends of the second elastic member abut against the second wedge 34 and the upper plate 31, respectively.

[0050] The first elastic element and the second elastic element include, but are not limited to, springs, tension springs, etc.; the first wedge 33 is slidably mounted on the upper plate 31 along the first direction via the first guide rod 35; the second wedge 34 is slidably mounted on the upper plate 31 along the first direction via the second guide rod 36.

[0051] Specifically, when the upper mold assembly 3 and the lower mold assembly 4 are closed, both the first elastic element and the second elastic element are in a compressed state. The first elastic element ensures that the first wedge 33 and the first mating member 43 are not in rigid contact, and the second elastic element ensures that the second wedge 34 and the second mating member 44 are not in rigid contact. When the upper mold assembly 3 and the lower mold assembly 4 are separated, the elastic element of the first elastic element will drive the first guide rod 35 and the first wedge 33 to reset, and the elastic element of the second elastic element will drive the second guide rod 36 and the second wedge 34 to reset.

[0052] In one embodiment, such as Figure 4 As shown, the lower mold assembly 4 includes a first lower mold base 47, a second lower mold base 48, a third elastic element 49, and a fourth elastic element (not shown in the figure).

[0053] The first lower mold base 47 is mounted on the support base 1, and the first lower plate 41 is slidably mounted on the first lower mold base 47 along the second direction. The opposite ends of the third elastic member 49 are respectively connected to the first lower mold base 47 and the first lower plate 41.

[0054] The second lower mold base 48 is mounted on the support base 1, and the second lower plate 42 is slidably mounted on the second lower mold base 48 along the second direction. The opposite ends of the fourth elastic member are respectively connected to the second lower mold base 48 and the second lower plate 42.

[0055] The third elastic element 49 and the fourth elastic element include, but are not limited to, springs. The first lower plate 41 can be slidably mounted on the first lower mold base 47 via a guide rail slider assembly, a guide rod sliding sleeve assembly, etc., and the second lower plate 42 can be slidably mounted on the second lower mold base 48 via a guide rail slider assembly, a guide rod sliding sleeve assembly, etc.

[0056] Specifically, when the first lower plate 41 and the second lower plate 42 are combined, both the third elastic element 49 and the fourth elastic element are in a stretched state; when the upper mold assembly 3 and the lower mold assembly 4 are separated, the rebound force of the third elastic element 49 causes the first lower plate 41 to move away from the second lower plate 42, and the rebound force of the fourth elastic element causes the second lower plate 42 to move away from the first lower plate 41, thereby moving the first lower plate 41 and the second lower plate 42 to the reset position.

[0057] In one embodiment, such as Figure 4 As shown, the battery sealing mechanism also includes a first bracket 5, a second bracket 6, a first support wheel 51, and a second support wheel 61;

[0058] The first bracket 5 is mounted on the support base 1, and the first support wheel 51 is rotatably mounted on the first bracket 5 and abuts against the first lower plate 41;

[0059] The second bracket 6 is mounted on the support base 1, and the second support wheel 61 is rotatably mounted on the second bracket 6 and abuts against the second lower plate 42.

[0060] In this embodiment, the first support wheel 51 can support the first lower plate 41 from below, and the second support wheel 61 can support the second lower plate 42 from below. During the movement of the first lower plate 41 along the second direction, the first support wheel 51 rolls below the first lower plate 41, and during the movement of the second lower plate 42 along the second direction, the second support wheel 61 rolls below the second lower plate 42, thus ensuring the stability of the movement of the first lower plate 41 and the second lower plate 42 along the second direction.

[0061] In one embodiment, such as Figure 4 As shown, the first docking member 43 includes a first support block mounted on the first lower plate 41 and a first roller (not shown in the figure) rotatably mounted on the first support block; the first wedge 33 is provided with a first inclined surface 331, which is used to drive the first lower plate 41 to move along the second direction through the first roller;

[0062] The second docking member 44 includes a second support block mounted on the second lower plate 42 and a second roller rotatably mounted on the second support block; the second wedge 34 is provided with a second inclined surface, which is used to drive the second lower plate 42 to move along the second direction through the second roller.

[0063] Both the first inclined surface 331 and the second inclined surface are inclined toward the second direction.

[0064] In this embodiment, as the first wedge 33 moves the first docking member 43 along the second direction, the first roller rolls along the first inclined surface 331, thereby reducing the friction between the first wedge 33 and the first docking member 43 and ensuring the stability of the docking between the first wedge 33 and the first docking member 43. Similarly, as the second wedge 34 moves the second docking member 44 along the second direction, the second roller rolls along the second inclined surface, thereby reducing the friction between the second wedge 34 and the second docking member 44 and ensuring the stability of the docking between the second wedge 34 and the second docking member 44.

[0065] In one embodiment, such as Figure 1 and Figure 4 As shown, the battery sealing mechanism also includes a support guide block 7 installed on the support base 1, and the support guide block 7 is provided with a storage slot 71 for storing the battery case 101.

[0066] The support guide block 7 is located below the first lower plate 41 and the second lower plate 42. Furthermore, the storage slot 71 is equipped with a magnetic suction element for attracting the battery case 101.

[0067] In this embodiment, when the first lower mold 45 and the second lower mold 46 are closed, the first lower mold 45 and the second lower mold 46 can clamp the battery case 101 on the support guide block 7. During the clamping process, the battery case 101 can move along the second direction, thereby ensuring the positional accuracy of the battery case 101 during the closing process of the upper mold assembly 3 and the lower mold assembly 4, and ensuring the stability of the upper part of the battery case 101 surrounding the positive electrode cap 102.

[0068] In one embodiment, such as Figure 1 and Figure 4 As shown, the battery sealing mechanism also includes a first guide rail 8 mounted on the support base 1. The support guide block 7 is provided with a first guide groove (not shown in the figure) adapted to the first guide rail 8. The support guide block 7 is slidably mounted on the first guide rail 8 along a third direction through the first guide groove; wherein, the first direction, the second direction and the third direction are perpendicular to each other.

[0069] The first guide rail 8 is fixedly installed on the support base 1 along the third direction, and the support guide block 7 can store a plurality of battery cases 101 distributed at intervals along the third direction.

[0070] In this embodiment, the support guide block 7 can move along the first guide rail 8, so that different battery shells 101 on the support guide block 7 can move along the third direction to between the first lower mold 45 and the second lower mold 46, which improves the convenience of loading and unloading the battery sealing mechanism.

[0071] Furthermore, the battery sealing mechanism also includes a moving drive component, the output end of which is connected to the support guide block 7, and the moving drive component is used to drive the support guide block 7 to move along the third direction.

[0072] In one embodiment, such as Figure 1 As shown, the battery sealing mechanism also includes a sliding component 9, and the upper plate 31 is slidably mounted on the support base 1 along the first direction via the sliding component 9.

[0073] The sliding component 9 includes, but is not limited to, a guide rail slider assembly and a guide rod sleeve assembly. In one specific embodiment, the sliding component 9 includes a second guide rail and a second slider. The second guide rail is mounted on the support base 1 along the first direction, and the second slider is mounted on the upper plate 31 and slidably connected to the second guide rail.

[0074] In this embodiment, the design of the sliding component 9 increases the load capacity of the upper plate 31 and ensures the stability of the upper plate 31 as it moves along the first direction.

[0075] In one embodiment, such as Figure 1 As shown, the upper plate 31 is equipped with at least two upper molds 32 spaced apart; the first lower plate 41 is equipped with at least two first lower half molds 45 spaced apart, and the second lower plate 42 is equipped with at least two second lower half molds 46 spaced apart; the upper molds 32, the first lower half molds 45 and the second lower half molds 46 are arranged in a one-to-one correspondence.

[0076] The number of the upper mold 32, the first lower mold, and the second lower half mold can be set according to actual needs.

[0077] Specifically, the battery casing 101 can be gradually moved under different upper molds 32, so that the battery casing 101 and the battery casing 101 can be squeezed by different upper molds 32. Different upper molds 32 can gradually increase the clamping force between the positive electrode cap 102 and the battery casing 101, further ensuring the stability of the positive electrode cap 102 covering the battery casing 101.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
