[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0032] The present invention provides a battery packaging mechanism. Figure 1 As shown, the battery packaging mechanism includes a mounting assembly 2, multiple groups of head assemblies 3 and a first driving member 1, the mounting assembly 2 includes a first mounting seat 21 and a second mounting seat 22, the first mounting seat 21 includes two first mounting columns 211, and the two first mounting columns 211 are spaced apart in the first direction; multiple groups of head assemblies 3 are spaced apart in the second direction, and the second direction is perpendicular to the first direction. Each group of head assemblies 3 includes a first head 31 and a second head 32, and the first head 31 and the second head 32 are opposite and spaced apart in the second direction, wherein the first head 31 is installed on the two first mounting columns 211, and the second head 32 is installed on the second mounting seat 22; the first driving member 1 connects the two first mounting columns 211 to drive the first head 31 to move relative to the second head 32 in the second direction.

[0033] The battery packaging mechanism of the present invention is provided with a mounting assembly 2 and multiple sets of head assemblies 3, wherein the mounting assembly 2 includes a first mounting seat 21 and a second mounting seat 22, the first mounting seat 21 includes two first mounting columns 211, and the two first mounting columns 211 are spaced apart in the first direction; the multiple sets of head assemblies 3 are spaced apart in the second direction, and the second direction is perpendicular to the first direction, and each set of head assemblies 3 includes a first head 31 and a second head 32, the first head 31 and the second head 32 are opposite and spaced apart in the second direction, and the first head 31 is installed on the two first mounting columns 211 spaced apart in the first direction. The first mounting post 211 is mounted on the second mounting seat 22, and the second head 32 is mounted on the second mounting seat 22. At the same time, the first driving member 1 connects and drives the two first mounting posts 211, thereby driving the first head 31 to move relative to the second head 32 in the second direction, thereby achieving the purpose of utilizing the first head 31 and the second head 32 to cooperate to encapsulate the battery filling port. In this process, since the first head 31 is mounted on two first mounting posts 211 set at intervals, the first head 31 will not shake during the movement toward the second head 32, which has a positive impact on the production quality and production consistency of the battery.

[0034] At the beginning of packaging, the polymer battery is placed between the first and second sealing heads 31, 32. The first driver 1 is activated, driving the two first mounting posts 211 and the first sealing head 31 thereon toward the second sealing head 32. As the first and second sealing heads 31, 32 approach, the space between them gradually decreases, ultimately clamping the packaging position, completing the packaging of the polymer battery. After packaging is complete, the first driver 1 and first sealing head 31 are reset to prepare for the next packaging operation.

[0035] The polymer battery is packaged through the coordinated operation of the first mounting base 21, the multiple sets of sealing head assemblies 3, and the first driving member 1. The packaging process is highly automated, reducing manual intervention and operational difficulty.

[0036] In a specific embodiment, Figure 1 As shown, the first mounting base 21 also includes a first connecting base 212, which is connected to one end of the two first mounting columns 211, and the first driving member 1 is arranged on a side of the first connecting base 212 away from the first mounting columns 211 and is connected to the first connecting base 212.

[0037] Specifically, the first driving member 1 is arranged on the side of the first connecting seat 212 away from the first mounting column 211, so that it cooperates with the first connecting seat 212 to drive the two first mounting columns 211 to move. This can make the product of the length and width of the polymer battery packaging structure smaller, and more battery packaging mechanisms can be arranged in a limited space.

[0038] In a specific embodiment, Figure 4As shown, the battery packaging mechanism also includes a guide assembly 4, which includes two fixing seats 41 and two first guide columns 42. The two fixing seats 41 are spaced apart in the first direction, and the two first guide columns 42 are extended in the first direction. The two first guide columns 42 are installed on the two fixing seats 41, and the two first mounting columns 211 are slidably connected to the two first guide columns 42 respectively.

[0039] Specifically, guide assembly 4 limits the motion trajectory of first mounting post 211, effectively preventing it from shaking or deflecting during movement, thereby enhancing the stability of the entire packaging mechanism. Guide assembly 4 ensures that first mounting post 211 can move along a predetermined path, which is crucial for achieving precise packaging operations. Guide assembly 4 helps reduce errors and defective product rates during the packaging process, further improving product quality and consistency.

[0040] In one embodiment, the guide assembly 4 further includes two first bearing seats 43 . The two first bearing seats 43 are respectively connected to the two first mounting posts 211 . The two first bearing seats 43 are respectively sleeved on the two first guide posts 42 .

[0041] Specifically, first mounting post 211 and first guide post 42 are connected by first bearing seat 43, achieving a sliding connection between the two. The primary function of first bearing seat 43 is to reduce friction between the first mounting post 211 and the first guide post 42, thereby improving the smoothness and efficiency of movement. As a sliding support component, first bearing seat 43 effectively carries and distributes loads during movement, protecting first mounting post 211 and first guide post 42 from wear.

[0042] In a specific embodiment, Figure 4 As shown, the guide assembly 4 includes four first bearing seats 43, two of which are connected to one of the first mounting columns 211 and sleeved on one of the first guide columns 42, and the other two first bearing seats 43 are connected to another first mounting column 211 and sleeved on another first guide column 42.

[0043] Specifically, in this embodiment, the first mounting column 211 and the first guide column 42 are slidingly connected through two first bearing seats 43. Compared with the embodiment in which the first mounting column 211 and the first guide column 42 are slidingly connected only through one first bearing seat 43, it can further ensure that the first mounting column 211 becomes more stable during the movement, thereby ensuring the packaging quality and packaging uniformity of the battery.

[0044] In a specific embodiment, Figure 1 and Figure 4As shown, the first driving member 1 is in contact with the first connecting seat 212, and the battery packaging mechanism also includes two first springs 44, which are respectively mounted on the two first guide columns 42 and clamped between the first bearing seat 43 and the fixed seat 41 away from the first connecting seat 212 to compress and store energy when the first head 31 approaches the second head 32.

[0045] Specifically, the first driving member 1 is in contact with the first connecting seat 212, which means that when the first driving member 1 drives the first connecting seat 212 and drives the first mounting column 211 and the first head 31, the first connecting seat 212, the first mounting column 211 and the first head 31 will not automatically reset. At this time, a reset tool is required. In the utility model, the elastic force of the first spring 44 is used to reset them. The first spring 44 compresses and stores energy, thereby releasing the energy to drive the first connecting seat 212, the first mounting column 211 and the first head 31 to reset; at the same time, the compression and storage of the first spring 44 can also effectively absorb and alleviate the impact and vibration generated when the first head 31 and the second head 32 contact and clamp the polymer battery, protecting the packaging mechanism and the battery from damage. The addition of the first spring 44 can balance these forces, ensure the stability and consistency of the packaging process, and reduce the defective rate by reducing equipment damage and maintenance costs caused by impact and vibration, and improving packaging quality and consistency. The introduction of the first spring 44 helps to reduce overall production costs.

[0046] In another embodiment, the first driving member 1 is connected to the first connecting seat 212 , and the first driving member 1 can drive the first sealing head 31 to move toward and away from the second sealing head 32 .

[0047] In a specific embodiment, Figure 5 As shown, the mounting assembly 2 further includes a first heat insulation plate 23 , and each first bearing seat 43 is connected to the first mounting column 211 via the first heat insulation plate 23 .

[0048] The first heat shield 23 is used to insulate the first mounting post 211 from the first bearing seat 43, preventing deformation of the first bearing seat 43 caused by excessive temperatures. The provision of the first heat shield 23 significantly improves the safety of the battery packaging mechanism, effectively preventing heat damage to the device and reducing the risk of malfunctions and accidents caused by high temperatures. This improves the safety, stability, and performance of the device.

[0049] In a specific embodiment, a heating element (not shown) is disposed inside the two first mounting posts 211. The heating element is used to heat the first sealing head 31 to perform hot-melt sealing on the battery.

[0050] The heating element is arranged inside the first mounting column 211, which can avoid direct heat radiation to the external environment. The first head 31 is arranged on two first mounting columns 211 arranged at intervals, so there are two positions for heating the first head 31, which can ensure that the first head 31 is heated evenly, thereby improving the packaging quality.

[0051] In a specific embodiment, Figure 3 As shown, the second head 32 is fixed on the second mounting seat 22, and the first head 31 includes: a mounting block 311, two first screws (not shown), a heat sealing block 312 and a second screw (not shown), the mounting block 311 is provided with two first waist-shaped holes 3111 extending in the second direction, the first waist-shaped holes 3111 pass through the mounting block 311 in the third direction, the two first waist-shaped holes 3111 are spaced apart in the first direction, and the third direction is perpendicular to the first direction and the second direction; the mounting block 311 is also provided with a first waist-shaped hole 3111 extending in the third direction. Two waist-shaped holes 3112, the second waist-shaped hole 3112 passes through the mounting block 311 in the second direction; the two first mounting columns 211 are provided with first mounting holes (not shown) arranged along the third direction; the two first screws are respectively inserted into the two first waist-shaped holes 3111 and the two first mounting holes; the heat sealing block 312 is installed on the side of the mounting block 311 close to the second head 32; the heat sealing block 312 is provided with a second mounting hole (not shown) arranged along the first direction on the side facing the mounting block; the second screw is sequentially inserted into the second waist-shaped hole 3112 and the second mounting hole.

[0052] Specifically, the design of the first waist-shaped hole 3111 enables the mounting block 311 to have a certain adjustment range in the second direction, and the design of the second waist-shaped hole 3112 enables the heat sealing block 312 to have a certain adjustment range in the third direction. By implementing this embodiment, it can be ensured that when an assembly error causes deviation from the preset position, the first head 31 and the second head 32 can be aligned by adjusting the mounting block 311 and the heat sealing block 312, thereby improving the packaging quality.

[0053] In a specific embodiment, Figure 1 and Figure 2 As shown, the second mounting base 22 includes two second mounting columns 221 and a second connecting base 222, the two first mounting columns 211 and the two second mounting columns 221 are alternately arranged in the first direction, the second head 32 is installed on the two second mounting columns 221, and the second connecting base 222 is connected to one end of the two second mounting columns 221. The battery packaging mechanism also includes a second driving member 5, which is arranged on the side of the second connecting base 222 away from the second mounting column 221 and is connected to the second connecting base 222 to drive the second head 32 to move relative to the first head 31 in the second direction.

[0054] Specifically, the second driving member 5 is arranged on the side of the second connecting seat 222 away from the second mounting column 221, and is connected to the second connecting seat 222 to drive the second head 32 to move relative to the first head 31 in the second direction. Compared with the first head 31 moving toward the second head 32 alone, the implementation of this embodiment can speed up the packaging efficiency of the battery packaging mechanism; since the second head 32 is installed on two spaced-apart second mounting columns 221, the second head 32 will not shake during the movement toward the first head 31; the second driving member 5 is arranged on the side of the second connecting seat 222 away from the second mounting column 221, so that it cooperates with the second connecting seat 222 to drive the two second mounting columns 221 to move, so that the product of the length and width of the packaging mechanism of the polymer battery can be made smaller, and more battery packaging mechanisms can be arranged in a limited space.

[0055] Furthermore, if Figure 4 As shown, the guide mechanism also includes two second guide columns 45, the two first guide columns 42 and the two second guide columns 45 are alternately arranged in the first direction, the two second guide columns 45 are installed on the two fixing seats 41, and the two second mounting columns 221 are slidingly connected to the two second guide columns 45 respectively; the second guide columns 45 have a similar effect to the first guide columns 42, and are used to limit the movement trajectory of the second mounting columns 221, effectively preventing the second mounting columns 221 from shaking and deflecting during the movement, which will not be repeated here.

[0056] Furthermore, if Figure 4 As shown, the guide mechanism further includes two second bearing seats 46, which are respectively connected to the two second mounting posts 221 and respectively sleeved on the two second guide posts 45. The second bearing seats 46 have similar functions to the first bearing seats 43, further ensuring that the second mounting posts 221 are more stable during movement, thereby ensuring the packaging quality and uniformity of the battery. Detailed description thereof will not be given here.

[0057] Furthermore, if Figure 4 As shown, the battery packaging mechanism also includes two second springs 47, which are respectively mounted on the two second guide posts 45 and sandwiched between the second bearing seat 46 and the fixing seat 41 away from the second connecting seat 222. They compress and store energy when the second head 32 approaches the first head 31. The second springs 47 have similar functions to the first springs 44, absorbing and alleviating the impact and vibration generated when the first and second heads 31, 32 contact and clamp the polymer battery, and resetting the second mounting post 221. Details thereof will not be repeated here.

[0058] Furthermore, if Figure 4 and Figure 5As shown, the mounting assembly 2 also includes a second thermal insulation plate 24. Each second bearing seat 46 is connected to a second mounting post 221 via the second thermal insulation plate 24. A heating element (not shown) is provided within each second mounting post 221. The second thermal insulation plate 24, similar to the first thermal insulation plate 23, is used to provide thermal insulation between the second mounting post 221 and the second bearing seat 46. A detailed description thereof will not be repeated here.

[0059] In a specific embodiment, Figure 2 and Figure 3 As shown, a first avoidance groove 313 is provided at a position of the first head 31 close to the second mounting column 221 to avoid the second mounting column 221; a second avoidance groove 321 is provided at a position of the second head 32 close to the first mounting column 211 to avoid the first mounting column 211.

[0060] Specifically, the first head 31 and the second head 32 are respectively provided with a first avoidance groove 313 and a second avoidance groove 321, which can effectively avoid the first head 31 and the second head 32 from colliding with the second mounting column 221, and the second head 32 from colliding with the first mounting column 211 during the movement of the first head 31 and the second head 32, thereby effectively ensuring the safety of the polymer battery packaging.
