[0003] Cell packaging is a key process in battery cell manufacturing, involving wrapping the battery cell with an aluminum-plastic film. During packaging, fixtures are used to secure the battery cell and the aluminum-plastic film. Traditional cell packaging fixtures can only hold cells of specific sizes; for cells of different thicknesses, fixtures of corresponding sizes must be used, and further adjustments are required after fixture replacement, impacting production efficiency. Summary of the Invention

[0009] The height of the adjustment plate relative to the clamping surface in the direction of cell thickness is adjustable, so as to adjust the height of the clamping space used to clamp the aluminum-plastic film and the cell in the direction of cell thickness.

[0010] The battery cell packaging fixture provided in this application embodiment features an openable first and second clamping disc. Opening the first and second discs allows for the placement and removal of the aluminum-plastic film and battery cell to be packaged, while closing them secures the film and cell for subsequent packaging operations. An adjustment plate is provided on the clamping surface of at least one of the first and second clamping discs. Adjusting the height of the adjustment plate relative to its clamping surface in the battery cell thickness direction allows for adjustment of the clamping space around the battery cell after the first and second discs are closed. This enables the battery cell packaging fixture to be suitable for various battery cells of different thicknesses, reducing or eliminating the need for fixture replacements, saving equipment costs, and improving production efficiency.

[0011] In some embodiments, the surface of the adjustment plate facing away from the clamping surface is configured as a support surface for placing the battery cell, and the support surface is arranged parallel to the clamping surface.

[0012] The battery cell packaging fixture provided in this application embodiment ensures that the adjusting plate only adjusts the height of the clamping space, preventing the battery cell from tilting within the clamping space, thus facilitating the positioning of the battery cell during subsequent packaging. Furthermore, the height of the adjusting plate relative to the clamping surface can be adjusted using the clamping surface as a reference.

[0013] In some embodiments, the adjustment plate is provided with an adjustment member, which is used to adjust the distance between the adjustment plate and the clamping surface in the direction of cell thickness.

[0014] The battery cell packaging fixture provided in this application embodiment can adjust the distance between the adjustment plate and the clamping surface in the direction of battery cell thickness by setting an adjustment component.

[0015] In some embodiments, the adjusting member is configured as a threaded member, which is threadedly connected to the adjusting plate and rotatably connected to the corresponding first clamping plate and / or second clamping plate. The threaded member can be screwed to move the adjusting plate along the axial direction of the threaded member.

[0016] The battery cell packaging fixture provided in this application embodiment can adjust the position of the adjusting plate through the threaded part, thereby changing the distance between the adjusting plate and the clamping surface; at the same time, the threaded part also serves to support the adjusting plate to ensure that the adjusting plate is firmly installed on the first clamping plate and / or the second clamping plate.

[0017] In some embodiments, the adjustment plate is provided with multiple negative pressure adsorption disks, which are used for vacuum adsorption of aluminum-plastic film.

[0018] The battery cell packaging fixture provided in this application embodiment can fix the aluminum-plastic film on the first fixture plate and the second fixture plate, preventing the aluminum-plastic film from shifting or falling off during the closing process of the first fixture plate and the second fixture plate.

[0023] In some embodiments, the adjustment plate on the first clamping plate is configured as the first adjustment plate, and the cell packaging fixture further includes an ejection assembly for ejecting the cell wrapped in aluminum-plastic film away from the first adjustment plate.

[0024] The battery cell packaging fixture provided in this application embodiment, by setting an ejection component, makes it easier to remove the packaged battery cell from the first fixture plate.

[0025] In some embodiments, the ejection component includes:

[0026] The push rod drive is located on the side of the first clamping plate opposite to the clamping space;

[0027] Multiple push rods are spaced apart. One end of each push rod is movably inserted through a first adjusting plate, and the other end is connected to the drive end of a push rod drive component. The push rod drive component is used to drive the push rods to reciprocate.

[0028] The battery cell packaging fixture provided in this application embodiment has a push rod that moves away from the clamping space and then returns to the first adjusting plate to avoid affecting the normal load-bearing function of the first support surface. When it is necessary to eject the battery cell, the push rod drive will drive the push rod to move into the clamping space until the battery cell is ejected from the first support surface.

[0029] In some embodiments, the ejection component further includes:

[0032] In some embodiments, the cell packaging fixture further includes a base, a fixed end of the push rod drive member, and a first clamping plate fixed to the base, and the ejection assembly further includes:

[0033] The guide post is slidably mounted on the base along the moving direction of the top rod, and is connected to the connecting plate.

[0034] The battery cell packaging fixture provided in this application provides guidance for the reciprocating movement of the connecting plate by setting guide posts, which helps the connecting plate and multiple push rods to move more smoothly.

The second adjusting plate moves within the second mounting groove to adjust the distance between the second supporting surface and the second clamping surface.

[0037] In some embodiments, the cell packaging fixture further includes:

[0038] A flip drive assembly is used to drive the second clamping disk to rotate relative to the first clamping disk.

[0039] The battery cell packaging fixture provided in this application embodiment drives the second clamping disk to rotate relative to the first clamping disk by setting a flipping drive component, so as to realize the opening and closing of the second clamping disk and the first clamping disk.

[0040] In some embodiments, the flip-drive component includes:

[0041] Servo motor;

[0042] A connector connects the second clamping disk and the output shaft of the servo motor, and the servo motor drives the second clamping disk to rotate through the connector.

[0044] The aforementioned cell packaging fixture and cell packaging equipment, by providing an openable first clamping plate and a second clamping plate, allow for the placement and removal of the aluminum-plastic film and cell to be packaged, and then clamp the aluminum-plastic film and cell by closing them, enabling subsequent packaging operations to proceed smoothly. An adjustment plate is provided on the clamping surface of at least one of the first and second clamping plates. By adjusting the height of the adjustment plate relative to its clamping surface in the cell thickness direction, the height of the clamping space for the cell after the first and second clamping plates are closed can be adjusted. This allows the cell packaging fixture to be applicable to cell thicknesses of various sizes, reducing or eliminating the need for fixture replacements, saving equipment costs, and improving production efficiency.

Detailed Implementation

[0050] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0051] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0052] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0053] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0054] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0055] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0056] Currently, judging from market trends, the application of batteries is becoming increasingly widespread. Batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of the application areas of power batteries, the market demand for them is also constantly increasing.

[0057] During battery assembly, the battery cells need to be encapsulated, which involves wrapping the cells with an aluminum-plastic film. Generally, clamps are used to secure the cells and the film during encapsulation. Traditional cell encapsulation clamps typically consist of two clamping discs. When the two discs are closed, the aluminum-plastic film is folded in half to wrap around the cell, clamping the film and cell for subsequent encapsulation. However, the clamping space created when the two discs are closed has a specific height, limiting its capacity to cells of a specific thickness. For cells of different thicknesses, clamps of corresponding sizes are required, and further adjustments are needed after each clamping change, impacting production efficiency and hindering adaptation to battery production cycles.

[0058] Based on the above considerations, in order to solve the problem of needing to change the packaging size according to the cell thickness during the battery cell packaging process, the inventors, after in-depth research, designed a battery cell packaging fixture, including a first clamping plate, a second clamping plate, and an adjusting plate. The second clamping plate and the first clamping plate are closable. By setting the adjusting plate on at least one of the first clamping plate and the second clamping plate, and by adjusting the height of the adjusting plate relative to the first clamping plate or the second clamping plate, the height of the clamping space for holding the battery cell formed when the first clamping plate and the second clamping plate are closed can be adjusted, thereby making it suitable for battery cells of different thicknesses.

[0059] The batteries ultimately manufactured using the cell packaging fixtures disclosed in this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. Specifically, these electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., while spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0060] Referring to Figure 1, Figure 1 shows a schematic diagram of the structure of the aluminum-plastic film 100 in one embodiment of this application. The aluminum-plastic film 100 provided in one embodiment of this application has two recesses 110. After the aluminum-plastic film 100 is folded in half, the two recesses 110 are aligned, thus forming a space for placing the battery cell inside the aluminum-plastic film 100. During assembly, the battery cell is placed in one of the recesses 110, and then the aluminum-plastic film 100 is folded in half again to cover it.

[0061] Referring to Figures 2 and 3, Figure 2 is a structural schematic diagram of a battery cell packaging fixture in an open state according to some embodiments of this application; Figure 3 is a structural schematic diagram of a battery cell packaging fixture in a closed state according to some embodiments of this application.

[0062] This application provides a battery cell packaging fixture for clamping and fixing the aforementioned aluminum-plastic film 100 and battery cell. The battery cell packaging fixture includes a first clamping disk 1, a second clamping disk 2, and an adjusting plate 3. The second clamping disk 2 and the first clamping disk 1 are closable. When the second clamping disk 2 and the first clamping disk 1 are closed, their mutually facing surfaces are each configured as their respective clamping surfaces. The adjusting plate 3 is disposed on the clamping surface of at least one of the first clamping disk 1 and the second clamping disk 2, for placing the aluminum-plastic film 100 and the battery cell. The height of the adjusting plate 3 relative to its clamping surface in the battery cell thickness direction is adjustable to adjust the height of the clamping space for clamping the aluminum-plastic film 100 and the battery cell in the battery cell thickness direction.

[0063] The battery cell packaging fixture provided in this application embodiment features an openable first clamping plate 1 and a second clamping plate 2. The first and second plates are opened to pick up and place the aluminum-plastic film 100 and the battery cell to be packaged, and then closed to clamp the aluminum-plastic film 100 and the battery cell, facilitating subsequent packaging operations. An adjustment plate 3 is provided on the clamping surface of at least one of the first and second clamping plates 1 and 2. By adjusting the height of the adjustment plate 3 relative to its clamping surface in the battery cell thickness direction, the height of the clamping space for the battery cell after the first and second clamping plates 1 and 2 are closed can be adjusted. This allows the battery cell packaging fixture to be applicable to various battery cells of different thicknesses, reducing or avoiding the need for fixture replacement, saving equipment costs, and improving production efficiency.

[0064] It is worth noting that, before placing the aluminum-plastic film 100 and the battery cell, as shown in Figure 2, the first clamping plate 1 and the second clamping plate 2 are first opened, and the aluminum-plastic film 100 is placed on the first clamping plate 1 and the second clamping plate 2, so that the two recesses 110 are respectively located on the clamping surfaces of the first clamping plate 1 and the second clamping plate 2. Then, the battery cell is placed into one of the recesses 110, so that the side of the battery cell in the thickness direction contacts the bottom of the recess 110. By closing the first clamping plate 1 and the second clamping plate 2, the aluminum-plastic film 100 is folded in half to wrap the battery cell, and the aluminum-plastic film 100 wrapped with the battery cell is clamped by the first clamping plate 1 and the second clamping plate 2.

[0065] Specifically, when the second clamping disk 2 is closed with the first clamping disk 1, the surface of the first clamping disk 1 facing the second clamping disk 2 is configured as the first clamping surface 12, and the surface of the second clamping disk 2 facing the first clamping disk 1 is configured as the second clamping surface 22.

[0066] In this embodiment of the application, the aforementioned adjustment plate 3 is provided on both the first clamping plate 1 and the second clamping plate 2. By adjusting the distance between the two adjustment plates 3, the height of the clamping space formed by the first clamping plate 1 and the second clamping plate 2 is adjusted.

[0067] It is understood that in some other embodiments, an adjustment plate 3 may be provided only on one of the first clamping disk 1 and the second clamping disk 2. The height of the clamping space can be adjusted by adjusting the height of the adjustment plate 3 on the first clamping disk 1 or the second clamping disk 2 relative to the clamping surface, thereby adjusting the distance between the adjustment plate 3 and the clamping surface of the other clamping disk 1 and the second clamping disk 2.

[0068] In some embodiments, the surface of the adjusting plate 3 facing away from the clamping surface is configured as a support surface for placing the aluminum-plastic film 100, and the support surface is arranged parallel to the clamping surface. This ensures that the adjusting plate 3 only adjusts the height of the clamping space, preventing the battery cell from tilting within the clamping space, thus facilitating the positioning of the battery cell during subsequent packaging. Furthermore, the height of the adjusting plate 3 relative to the clamping surface can be adjusted using the clamping surface as a reference.

[0069] In some embodiments, the adjusting plate 3 is provided with an adjusting member 4, which is used to adjust the distance between the adjusting plate 3 and the clamping surface in the direction of cell thickness. By providing the adjusting member 4, the distance between the adjusting plate 3 and the clamping surface in the direction of cell thickness can be adjusted.

[0070] Optionally, the adjusting member 4 is a threaded member, which is threadedly connected to the adjusting plate 3 and rotatably connected to the corresponding first clamping disk 1 and / or second clamping disk 2. The threaded member can be screwed to move the adjusting plate 3 along its axial direction. While the threaded member is rotatably connected to the corresponding first clamping disk 1 and / or second clamping disk 2, its axial movement is restricted. Thus, the position of the adjusting plate 3 can be adjusted via the threaded member, thereby changing the distance between the adjusting plate 3 and the clamping surface. Simultaneously, the threaded member also supports the adjusting plate 3, ensuring its secure installation on the first clamping disk 1 and / or second clamping disk 2.

[0071] Threaded parts can specifically be adjusting screws or adjusting rods. Adjusting screws and adjusting rods are common components for adjusting the distance between two structures. Their specific structure and working principle will not be elaborated here.

[0072] Optionally, each adjusting plate 3 is provided with multiple adjusting components 4, which are spaced apart and work together to support and adjust the adjusting plate 3, so as to ensure that the adjusting plate 3 is installed stably and adjusted accurately.

[0073] Specifically, the adjusting plate 3 on the first clamping plate 1 is configured as a first adjusting plate 31, and the adjusting member 4 that adjusts the distance between the first adjusting plate 31 and the first clamping surface 12 in the cell thickness direction is an adjusting screw. The cell packaging fixture also includes a base 8, on which the first clamping plate 1 is disposed. One end of the adjusting screw is rotatably connected to the base 8, and the other end of the adjusting screw passes through the first clamping plate 1 and is threadedly connected to the side of the first adjusting plate 31 facing away from the first support surface 311.

[0074] The adjusting plate 3 on the second clamping plate 2 is configured as a second adjusting plate 32. The adjusting component 4, which adjusts the distance between the second adjusting plate 32 and the second clamping surface 22 in the direction of cell thickness, is an adjusting screw. The screw head of the adjusting screw protrudes from the second support surface 321 to the outside, so that the adjusting screw can be turned by the exposed screw head.

[0075] In some embodiments, the adjusting plate 3 is provided with multiple negative pressure adsorption disks 5, which are used for vacuum adsorption of the aluminum-plastic film 100. Specifically, multiple negative pressure adsorption disks 5 are respectively provided on the first adjusting plate 31 and the second adjusting plate 31. In this way, the aluminum-plastic film 100 can be fixed on the first clamping disk 1 and the second clamping disk 2, preventing the aluminum-plastic film 100 from shifting or falling off during the closing process of the first clamping disk 1 and the second clamping disk 2.

[0076] In some embodiments, one side of the second clamping disk 2 is rotatably connected to the first clamping disk 1. The aluminum-plastic film 100 is placed on the first clamping disk 1 and the second clamping disk 2. The battery cell is placed on the first clamping disk 1 and located above the aluminum-plastic film 100. Flipping the second clamping disk 2 can fold the aluminum-plastic film 100 in half to wrap the battery cell. Specifically, the second clamping disk 2 and the first clamping disk 1 can be rotatably connected by a structure such as a pivot or hinge.

[0077] By rotating the second clamping disc 2 to connect it to the first clamping disc 1, the aluminum-plastic film 100 can be folded in half by gradually flipping the second clamping disc 2, so as to wrap the battery cell with the aluminum-plastic film 100.

[0078] Optionally, the second clamping plate 2 can be opened to an angle of 180 degrees with the first clamping plate 1. At this time, the first support surface 311 and the second support surface 321 are parallel, and the aluminum-plastic film 100 will be laid flat on the first support surface 311 and the second support surface 321 without being folded.

[0079] In some embodiments, referring to Figures 2 and 3, in order to drive the second clamping disk 2 and the first clamping disk 1 to open and close, the cell packaging fixture further includes a flip drive assembly 7, which is used to drive the second clamping disk 2 to rotate relative to the first clamping disk 1. By setting the flip drive assembly 7 to drive the second clamping disk 2 to rotate relative to the first clamping disk 1, the opening and closing of the second clamping disk 2 and the first clamping disk 1 can be achieved. Specifically, the fixed end of the flip drive assembly 7 is disposed on the base 8.

[0080] Optionally, the flip drive assembly 7 includes a servo motor 71 and a connector 72. The connector 72 connects the second clamping disk 2 and the output shaft of the servo motor 71. The servo motor 71 drives the second clamping disk 2 to flip through the connector 72.

[0081] In some embodiments, the output shaft of the servo motor 71 is coaxially arranged with the rotation axis of the second clamping disk 2, and the connection point between the connector 72 and the second clamping disk 2 avoids the rotation axis of the second clamping disk 2. When the servo motor 71 drives the connector 72 to rotate, the connector 72 will drive the second clamping disk 2 to rotate synchronously.

[0082] In other embodiments, the flipping drive component 7 can also be configured as a rotary cylinder, which can drive the second clamping disk 2 to rotate and open relative to the first clamping disk 1. The specific structural form of the flipping drive component 7 is not limited.

[0083] In some embodiments, a first receiving groove 11 is provided on the first clamping plate 1, and an adjusting plate 3 on the first clamping plate 1 is configured as a first adjusting plate 31. A first mounting groove is provided at the bottom of the first receiving groove 11, and the first adjusting plate 31 is movably disposed within the first mounting groove. By providing a first receiving groove 11 on the first clamping plate 1, clamping space is reserved for the aluminum-plastic film 100 and the battery cell. The first adjusting plate 31 moves within the first mounting groove to adjust the distance between the first supporting surface 311 and the first clamping surface 12.

[0084] Specifically, the first adjusting plate 31 can be moved to be flush with or lower than the bottom surface of the first receiving groove 11 (i.e., the first clamping surface 12). At this time, the first clamping surface 12 will provide support for the aluminum-plastic film 100.

[0085] The second clamping plate 2 is provided with a second receiving groove 21, and the adjusting plate 3 on the second clamping plate 2 is set as a second adjusting plate 32. The bottom of the second receiving groove 21 is provided with a second mounting groove, and the second adjusting plate 32 is movably disposed in the second mounting groove. By providing a second receiving groove 21 on the second clamping plate 2, clamping space is reserved for the aluminum-plastic film 100 and the battery cell. The second adjusting plate 32 moves within the second mounting groove to adjust the distance between the second supporting surface 321 and the second clamping surface 22.

[0086] Specifically, the second adjusting plate 32 can be moved to be flush with or lower than the bottom surface of the second receiving groove 21 (i.e., the second clamping surface 22). At this time, the second clamping surface 22 will provide support for the aluminum-plastic film 100.

[0087] In some embodiments, the cell packaging fixture further includes an ejection assembly 6, which is used to eject the cell wrapped with aluminum-plastic film 100 away from the first adjusting plate 31. This makes it easier to remove the packaged cell from the first fixture plate 1.

[0088] Optionally, the ejector assembly 6 includes an ejector rod drive 61 and multiple ejector rods 62. The ejector rod drive 61 is disposed on the side of the first clamping disk 1 opposite to the clamping space. The multiple ejector rods 62 are spaced apart, with one end of each ejector rod 62 movably passing through the first adjusting plate 31 and the other end connected to the drive end of the ejector rod drive 61. The ejector rod drive 61 is used to drive the ejector rods 62 to reciprocate. The ejector rod drive 61 may specifically be a cylinder.

[0089] When the push rod 62 moves away from the clamping space, it will return to the first adjusting plate 31 to avoid affecting the normal load-bearing function of the first support surface 311. When it is necessary to push the battery cell out, the push rod drive member 61 will drive the push rod 62 to move into the clamping space until the battery cell is pushed away from the first support surface 311.

[0090] In some embodiments, the ejector assembly 6 further includes a connecting plate 63, which is connected to the drive end of the ejector rod drive member 61, and multiple ejector rods 62 are connected to the connecting plate 63. Thus, by connecting the multiple ejector rods 62 with the connecting plate 63, the ejector rod drive member 61 can drive the connecting plate 63 to move, thereby driving the multiple ejector rods 62 to move synchronously.

[0091] Specifically, the fixed end of the push rod drive component 61 is fixed to the base 8, and the ejection assembly 6 also includes a guide post 64. The guide post 64 is slidably disposed on the base 8 along the moving direction of the push rod 62, and the guide post 64 is connected to the connecting plate 63.
