[0002] The aluminum-plastic packaging film is a multilayer composite film material composed of plastic, aluminum foil and adhesive, and has the characteristics of high strength, high barrier, electrolyte resistance and the like, and is commonly used for packaging soft package lithium batteries.

[0003] The packaging tool for packaging the soft package battery includes two flat heads, i.e., an upper head and a lower head. The part of the soft package battery to be packaged is located between the upper head and the lower head, and the packaging and fixation of the aluminum-plastic packaging film are achieved by the compression of the upper head and the lower head.

[0004] The soft package battery includes a top side to be packaged, a side edge to be packaged and a bottom side to be packaged. Since the top side of the soft package battery has a tab, the upper head required for the top side to be packaged is different from the upper heads required for the other two, i.e., one packaging tool can only be used for packaging the top side to be packaged of the soft package battery, or can only be used for packaging the side edge to be packaged and the bottom side to be packaged of the soft package battery, resulting in the need to switch at least two tools during the packaging process of the soft package battery, thereby increasing the packaging cycle and cost of the soft package battery.

[0007] In the application, the first packaging part and the second packaging part are arranged on the first head at the same time, so that the first head can meet the packaging requirements of different positions of the soft package battery, thereby reducing the number of tools required during the packaging process of the soft package battery, thereby reducing the packaging cost of the soft package battery.

[0030] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0032] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0034] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0035] Aluminum-plastic encapsulation film is a multi-layer composite film material composed of plastic, aluminum foil and adhesive. It has the characteristics of high strength, high barrier and electrolyte resistance, and is commonly used as the encapsulation for soft-pack lithium batteries.

[0036] Existing encapsulation fixtures for packaging pouch batteries include two flat end caps, an upper end cap and a lower end cap, distributed vertically. The part of the pouch battery to be packaged is located between the upper end cap and the lower end cap. The aluminum-plastic encapsulation film is packaged and fixed by pressing the upper end cap and the lower end cap together.

[0037] A pouch battery includes at least one of a top-side encapsulation portion, a side-side encapsulation portion, and a bottom-side encapsulation portion. Taking a pouch battery that includes a top-side encapsulation portion, a side-side encapsulation portion, and a bottom-side encapsulation portion as an example, since the top side of the pouch battery has tabs, the top end cap required for the top-side encapsulation portion is different from the top end cap required for the other two portions. That is, a single encapsulation tool can only encapsulate the top-side encapsulation portion of the pouch battery, or it can only encapsulate the side-side encapsulation portion and the bottom-side encapsulation portion of the pouch battery. This results in the need to switch at least two types of tooling during the pouch battery encapsulation process, increasing the encapsulation cycle and cost of the pouch battery.

[0038] To address the aforementioned problems, embodiments of this application provide a packaging fixture for a pouch battery, such as... Figure 1 As shown, the packaging fixture includes a first end cap 1 and a second end cap 2 disposed opposite to each other along a first direction X. The gap between the first end cap 1 and the second end cap 2 is used to accommodate the portion of the pouch battery to be packaged. The first direction X is perpendicular to the packaging surface of the pouch battery; wherein, as... Figure 2 and Figure 3 As shown, the first end cap 1 has a first encapsulation surface 15, the first encapsulation surface 15 has a first encapsulation portion 11 and a second encapsulation portion 12, the first encapsulation portion 11 and the second encapsulation portion 12 are arranged circumferentially along the first end cap 1, the first encapsulation portion 11 is used to encapsulate the top side of the soft pack battery to be encapsulated, and the second encapsulation portion 12 is used to encapsulate the side side of the soft pack battery to be encapsulated and / or the bottom side of the soft pack battery to be encapsulated.

[0039] When it is necessary to encapsulate the top part of the soft-pack battery, the first end cap 1 can be adjusted so that the first encapsulation part 11 and the second end cap 2 are directly opposite each other along the first direction X. When it is necessary to encapsulate the side part and / or the bottom part of the soft-pack battery, the first end cap 1 can be adjusted so that the second encapsulation part 12 and the second end cap 2 are directly opposite each other along the first direction X.

[0040] In this embodiment, by simultaneously providing a first encapsulation part 11 and a second encapsulation part 12 on the first end cap 1, the first end cap 1 can meet the encapsulation requirements of different positions of the soft-pack battery, thereby reducing the number of tooling required in the soft-pack battery encapsulation process, thus reducing the encapsulation cost of the soft-pack battery. At the same time, it reduces the number of times tooling needs to be switched during the soft-pack battery encapsulation process, which in turn helps to shorten the encapsulation cycle of the soft-pack battery and improve the encapsulation efficiency of the soft-pack battery.

[0041] The first encapsulation part 11 and the second encapsulation part 12 are arranged circumferentially along the first end cap 1, which helps to reduce the size of the first end cap 1, thereby facilitating the reduction of the overall size of the encapsulation fixture and reducing the material cost of the first end cap 1 and the encapsulation fixture.

[0042] In one embodiment, the position switching of the first packaging section 11 and the second packaging section 12 is manually controlled by the operator to simplify the structure of the packaging fixture.

[0043] In another embodiment, such as Figure 4 As shown, the packaging fixture includes a first driving member 3, which is drivenly connected to the first end cap 1. The first driving member 3 can drive the first end cap 1 to rotate so that the first packaging part 11 or the second packaging part 12 approaches or moves away from the second packaging surface 21 of the second end cap 2.

[0044] In this embodiment, the first end cap 1 is driven to rotate by the first driving member 3 to adjust the position of the first encapsulation part 11 and the second encapsulation part 12, so that one of the first encapsulation part 11 and the second encapsulation part 12 is directly opposite to the second encapsulation surface 21 in the first direction X. This simplifies the difficulty of adjusting the position of the first encapsulation part 11 and the second encapsulation part 12, thereby shortening the adjustment cycle of the first encapsulation part 11 and the second encapsulation part 12, and further shortening the encapsulation cycle of the soft pack battery.

[0045] like Figure 4 As shown, the packaging fixture includes a first plate 4, a first end cap 1 and a first driving component 3, both of which are mounted on the first plate 4; the outline shape of the first packaging surface 15 is arc-shaped, and the first packaging part 11 and the second packaging part 12 are arranged at intervals along the arc surface of the first packaging surface 15.

[0046] like Figure 5 As shown, the packaging fixture also includes a second plate 6 and a second driving member 5. The second driving member 5 is drivenly connected to the first plate 4 and is mounted on the second plate 6. One of the second plate 6 and the first plate 4 is provided with a first slide rail 61 extending along the second direction Y, and the other is provided with a first slider 1B1, for example, as... Figure 5As shown, the second plate 6 is provided with a first slide rail 61, and the first plate 4 is provided with a first slider 1B1. The first slide rail 61 and the first slider 1B1 cooperate, and the second driving member 5 can drive the first plate 4 to move along the second direction Y. The first plate 4 can drive the first end cap 1 to roll along the second direction Y. The second direction Y is parallel to the packaging surface of the soft pack battery, that is, the second direction Y is perpendicular to the first direction X, and both the first direction X and the second direction Y are perpendicular to the axial direction Z of the first end cap 1.

[0047] In this embodiment, the first end cap 1 is arc-shaped and can rotate around the output shaft of the first driving member 3. For example, the output shaft of the first driving member 3 is coaxially arranged with the arc-shaped first end cap 1, meaning the first driving member 3 can drive the first end cap 1 to rotate around its own axis. Simultaneously, the second driving member 5 can drive the first plate 4 to move along the second direction Y, thereby realizing the rolling of the first end cap 1 in the second direction Y. During the rolling process, the first end cap 1 can gradually press the packaged portion of the soft-pack battery with the second end cap 2. Furthermore, during the rolling process, some wrinkles in the aluminum-plastic encapsulation film can be pushed towards the edge, thereby reducing the number of wrinkles after the soft-pack battery is packaged. This reduces the risk of electrolyte leakage due to damage to the aluminum-plastic encapsulation film at the wrinkle locations, thus improving the packaging quality and processing yield of the soft-pack battery. Simultaneously, during the rolling process, excess electrolyte can be squeezed out of the aluminum-plastic encapsulation film, reducing the risk of poor packaging or even leakage of the soft-pack battery, further improving the packaging quality and processing yield of the soft-pack battery.

[0048] During the process of the second driving component 5 driving the first plate 4 to move along the second direction Y, the first slider 1B1 moves along the first slide rail 61. The cooperation between the first slider 1B1 and the first slide rail 61 can limit the movement direction of the first plate 4, thereby improving the accuracy and stability of the movement direction of the first plate 4.

[0049] In one embodiment, the first slider 1B1 is directly mounted on the first plate 4.

[0050] In another embodiment, such as Figure 5 As shown, the packaging fixture also includes a third plate 1B, which is fixed on the first plate 4. A first slider 1B1 is mounted on the third plate 1B, that is, the first slider 1B1 is indirectly mounted on the first plate 4. A second driving member 5 is drivenly connected to the third plate 1B. The second driving member 5 can drive the third plate 1B to move in the second direction Y. The third plate 1B can drive the first plate 4, the first end cap 1, and the first driving member 3 to move synchronously in the second direction Y.

[0051] In addition, such as Figure 5As shown, a first lead screw 62 extending along the second direction Y is provided on the second plate 6, and a first mating block 1B2 is provided on the third plate 1B. The first lead screw 62 is driven to be connected to the second driving member 5, and the first mating block 1B2 is threaded to be connected to the first lead screw 62. The second driving member 5 can drive the first lead screw 62 to rotate around its own axis. The rotation of the first lead screw 62 can drive the first mating block 1B2 to move along the second direction Y, thereby realizing that the second driving member 5 drives the first plate 4 to move in the second direction Y.

[0052] In this embodiment, the cooperation between the first lead screw 62 and the first mating block 1B2 can restrict the movement direction of the first plate 4 in the second direction Y, thereby improving the accuracy and stability of the movement direction of the first plate 4. At the same time, the cooperation between the first lead screw 62 and the first mating block 1B2 can achieve precise control of the movement distance of the first plate 4 in the second direction Y.

[0053] like Figure 1 As shown, the packaging fixture also includes a fourth plate 1C and a third driving member 7. The third driving member 7 is drivenly connected to the second plate 6 and is installed on the fourth plate 1C. One of the fourth plate 1C and the second plate 6 is provided with a second slide rail 1C1 extending along the first direction X, and the other is provided with a second slider 63. For example, the fourth plate 1C is provided with the second slide rail 1C1, and the second plate 6 is provided with the second slider 63. The second slide rail 1C1 and the second slider 63 cooperate. The third driving member 7 can drive the second plate 6 to move along the first direction X, and the second plate 6 can drive the first end cap 1 to move synchronously in the first direction X.

[0054] In this embodiment, the third driving member 7 can drive the second plate 6 to move along the first direction X. The second plate 6 can drive the second driving member 5, the first plate 4, the first end cap 1 and the first driving member 3 to move synchronously in the first direction X, thereby realizing the adjustment of the distance between the first end cap 1 and the second end cap 2 in the first direction X, so that the packaging fixture can meet the packaging requirements of soft-pack batteries of different thicknesses, thereby expanding the applicability of the packaging fixture.

[0055] The second slide rail 1C1 cooperates with the second slider 63. During the process of the third driving member 7 driving the second plate 6 to move along the first direction X, the second slider 63 can move along the second slide rail 1C1 to improve the accuracy and stability of the movement of the second plate 6 in the first direction X.

[0056] In addition, such as Figure 1As shown, the fourth plate 1C is provided with a second lead screw 1C2 extending along the first direction X, and the second plate 6 is provided with a second mating block 64. The second lead screw 1C2 is driven to be connected to the third driving member 7. The second lead screw 1C2 is threaded to the second mating block 64. The third driving member 7 can drive the second lead screw 1C2 to rotate around its own axis. The rotation of the second lead screw 1C2 can drive the second mating block 64 to move along the first direction X, thereby realizing that the third driving member 7 drives the second plate 6 to move in the first direction X.

[0057] In this embodiment, the cooperation of the second lead screw 1C2 and the second mating block 64 can restrict the movement direction of the second plate 6 in the first direction X, thereby improving the accuracy and stability of the movement direction of the second plate 6. At the same time, the cooperation of the second lead screw 1C2 and the second mating block 64 can achieve precise control of the movement distance of the second plate 6 in the first direction X.

[0058] like Figure 2 As shown, the first encapsulation part 11 has a groove 111, which is used to accommodate the tab of the pouch battery to reduce the risk of damage to the tab caused by the first end cap 1 squeezing the tab during the encapsulation process, thereby improving the yield of the pouch battery.

[0059] In any of the above embodiments, such as Figure 6 As shown, the packaging fixture includes a first heating element 8, which contacts the first end cap 1. The first heating element 8 can increase the temperature of the first end cap 1 to improve the packaging reliability of the aluminum-plastic packaging film.

[0060] In one embodiment, the first heating element 8 is disposed inside the first end cap 1.

[0061] In another embodiment, such as Figure 6 As shown, the first end cap 1 includes a first surface 13 and a second surface 14 disposed opposite to each other along its own thickness direction Z, and a first heating element 8 is attached to the first surface 13, and / or the first heating element 8 is attached to the second surface 14.

[0062] In this embodiment, the first heating element 8 is directly attached to the outer surface of the first end cap 1, which simplifies the connection between the first heating element 8 and the first end cap 1 and simplifies the structure of the first end cap 1, thereby reducing the cost of the first end cap 1 and the packaging tooling.

[0063] In any of the above embodiments, such as Figure 7 As shown, the packaging fixture includes a fixing block 9, and the second end cap 2 is mounted on the fixing block 9; the packaging fixture includes a second heating element 1A, and the second heating element 1A and the second end cap 2 are in indirect contact through the fixing block 9.

[0064] In this embodiment, the second heating element 1A is mounted on the fixing block 9, and the second heating element 1A and the second end cap 2 are indirectly in contact through the fixing block 9, which simplifies the connection structure between the second heating element 1A and the second end cap 2, thereby simplifying the structure of the second end cap 2 and reducing the cost of the second end cap 2.

[0065] In one embodiment, the second heating element 1A is directly attached to the surface of the fixing block 9 to simplify the structure of the fixing block 9.

[0066] In another embodiment, such as Figure 8 As shown, the fixing block 9 has a receiving cavity 91, and at least a portion of the second heating element 1A is located in the receiving cavity 91 and contacts the side wall of the receiving cavity 91.

[0067] In this embodiment, the second heating element 1A is placed inside the receiving cavity 91, which reduces the risk of the second heating element 1A being damaged by force during the packaging process, thereby extending the service life of the second heating element 1A and reducing the risk of the second end cap 2 being at a low temperature due to the damage of the second heating element 1A, that is, reducing the risk of the packaging being unstable due to the low temperature of the second end cap 2, thereby improving the packaging stability of the packaging fixture.

[0068] The second aspect of this application provides a packaging device for a pouch battery. The packaging device includes the packaging fixture described in any of the above embodiments. The packaging fixture has a first packaging part 11 and a second packaging part 12, which can meet the packaging requirements of different positions of the pouch battery, thereby reducing the packaging cost of the pouch battery and shortening the packaging cycle. The packaging fixture achieves packaging fixation by rolling the circular end cap, reducing the number of folds and the risk of leakage of the pouch battery. In addition, the packaging device has a highly adjustable function, which enables the packaging fixture to package and fix pouch batteries of different thicknesses.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
