[0032] The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are only for explaining the relevant utility model and are not intended to limit the utility model.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the embodiments.

[0034] In a first aspect, embodiments of this application provide a cell forming fixture 100, such as... Figure 1-4 As shown, it includes:

[0035] The clamping unit 10 includes a bearing body 11, a first limiting member and a second limiting member. The bearing body 11 has a bearing surface S1. The first limiting member and the second limiting member are respectively disposed on the bearing body 11. One of the first limiting member and the second limiting member is located in a first direction of the bearing body 11 and the other is located in a second direction of the bearing body 11. The first direction is perpendicular to the second direction.

[0036] The shaping unit 20 includes a shaping block 21 located in the second direction. The shaping block 21, the first limiting member, the second limiting member, and the bearing surface S1 define an adjustable accommodating space.

[0037] The vacuum unit includes a vacuum pipeline (not shown in the figure). When the battery cell is located in the housing space, the vacuum pipeline connects the contact area between the battery cell and the bearing surface S1 to exhaust the air between the battery cell and the bearing surface S1.

[0038] It should be noted that the battery cell in the embodiments of this application refers to the battery cell whose main body is encapsulated in an aluminum-plastic film.

[0039] It is understandable that the clamping unit 10 is mainly used to support and limit the battery cell. The supporting body 11, as the main body of the entire clamping unit 10, is mainly used to support the battery cell, the first limiting member, and the second limiting member. The supporting surface S1 of the supporting body 11 refers to the surface that supports the battery cell. When the battery cell is placed on the supporting body 11, the larger surface of the battery cell contacts the supporting surface S1 of the supporting body 11, and the side surfaces of the battery cell contact the first limiting member, the second limiting member, and the shaping block 21, respectively.

[0040] The first and second limiting components can be any type of fixing block, adjusting block 12, or stop block; one of the first and second limiting components is located in a first direction of the bearing body 11, and the other is located in a second direction of the bearing body 11. The first direction can be the width direction of the bearing body 11 (e.g., the width direction of the bearing body 11). Figure 1The second direction can be the length direction of the supporting body 11 (e.g., the Y direction). Figure 1 (in the X direction).

[0041] Specifically, when the first limiting member is located in the first direction of the support body 11, it is used to limit the battery cell from the first direction, and the second limiting member is located in the second direction of the support body 11, it is used to limit the battery cell from the second direction; when the first limiting member is located in the second direction of the support body 11, it is used to limit the battery cell from the second direction, and the second limiting member is located in the first direction of the support body 11, it is used to limit the battery cell from the first direction.

[0042] It is also understood that the shaping unit 20 is used to shape the battery cell, including folding, cutting, or sealing the edges. The shaping block 21 of the shaping unit 20 is set in the second direction. The shaping block 21, together with the bearing surface S1, the first limiting member, and the second limiting member, defines an adjustable accommodating space for accommodating battery cells of various sizes. When the battery cell is placed on the bearing surface S1, the shaping block 21 can fold, cut, or seal the sides of the battery cell. In some embodiments, after shaping one side of the battery cell, the other side of the battery cell can be shaped by rotating the battery cell 180 degrees, depending on the actual processing needs. When the shaping unit 20 performs the shaping operation on the battery cell, the shaping block 21 can be independent of the supporting body 11, or it can be set on the supporting body 11. The side of the shaping block 21 contacts the side of the battery cell to limit the position of the battery cell. The shaping block 21 can be a rectangular positioning plate or an L-shaped positioning plate. The embodiments of this application do not limit this.

[0043] It should be noted that the size of the accommodating space can be adjusted by adjusting the position of at least one of the first limiting member, the second limiting member, and the shaping block 21. For example, the first limiting member is movably connected to the bearing surface S1 and can move along the first direction to adjust the size of the accommodating space; as another example, the shaping block 21 can move toward or away from the bearing body 11 to adjust the size of the accommodating space.

[0044] In other embodiments, at least one of the shaping block 21, the first limiting member, and the second limiting member can also be along a third direction (e.g., Figure 1 The Z-direction (i.e., along the height direction of the supporting body 11) is moved, which is beneficial for accommodating battery cells of different thicknesses.

[0045] It is also understood that the vacuum unit is mainly used to generate negative pressure by drawing a vacuum. The vacuum unit includes a vacuum pipeline, which can be connected to an external vacuum device, such as a vacuum pump, to draw a vacuum and remove the air between the battery cell and the carrier surface S1. The vacuum pipeline can be a pipeline independent of the carrier body 11. When a vacuum is required, the vacuum pipeline is connected to the contact area between the battery cell and the carrier surface S1. In a preferred embodiment, the vacuum pipeline can also be set inside the carrier body 11 and connected to the carrier surface S1. When the battery cell is placed in the receiving space, the air between the battery cell and the carrier surface S1 is directly drawn out. The structure is simple, the operation is convenient, and it is beneficial to the compact structure of the entire battery cell forming fixture.

[0046] The cell forming fixture of this application solves the problems of existing fixtures being unable to meet the forming requirements of cells of various sizes, and being unable to reliably stabilize the position of the cells and guarantee the forming quality of the cells. The cell forming fixture of this application defines an adjustable accommodating space between the support body 11 of the clamping unit 10, the first limiting member, the second limiting member, and the shaping block 21 of the shaping unit 20. This facilitates compatibility with cells of various sizes, makes cell forming processing of various sizes convenient, and thus reduces battery processing costs. Furthermore, the shaping block 21 of the shaping unit 20, in conjunction with the clamping unit 10, facilitates the shaping of the cells, such as, but not limited to, folding, cutting, and sealing the edges. Additionally, the vacuum pipeline of the vacuum unit connects the cell to the support surface S of the support body 11. In the contact area, negative pressure is generated by venting the air between the battery cell and the bearing surface S1 of the bearing body 11. Under the action of negative pressure, it is beneficial to avoid displacement and deviation of the battery cell. For example, when the battery cell after stacking is covered with aluminum-plastic film, the negative pressure adsorption helps to prevent the stacked core and aluminum-plastic film from shifting and deviating, thereby stabilizing and fixing the position of the battery cell, avoiding mechanical damage to the battery cell, ensuring the forming quality of the battery cell, and thus improving the processing efficiency of the battery. The battery cell forming fixture of this utility model has a simple structure, is easy to process, and is convenient to operate.

[0047] As an optional solution, such as Figure 1 As shown, the vacuum pipeline is installed inside the supporting body 11. The vacuum unit also includes a connector 31 and a vacuum hole 30 that communicate with the vacuum pipeline. The vacuum hole 30 is opened on the supporting surface S1. The battery cell is located inside the housing space. Furthermore, the battery cell can completely cover the vacuum hole 30.

[0048] The connector 31 is located on the side of the supporting body 11 and is used to connect to external vacuum equipment.

[0049] It is understood that the vacuum pipeline can be a through channel set inside the support body 11 or a pipeline laid inside the support body 11; the location of the vacuum pipeline inside the support body 11 is conducive to making the entire support body 11 structure compact.

[0050] The vacuum hole 30 is located on the bearing surface S1, connecting the bearing surface S1 to the vacuum pipeline, thereby extracting the air between the battery cell and the bearing surface S1. The connector 31 is located on the side of the bearing body 11 and is mainly used to connect to external vacuum equipment. The position of the connector 31 helps to avoid the battery cell and will not damage the battery cell. At the same time, it can reliably generate negative pressure to stabilize the position of the battery cell.

[0051] It is also understood that the number of vacuum holes 30 can be one, two or more; when the battery cell is placed on the bearing surface S1, the vacuum hole 30 can be opened in the center of the bearing surface S1, that is, the vacuum hole 30 is located in the center of the orthographic projection of the battery cell on the bearing surface S1, and the air in the center of the contact area between the battery cell and the bearing surface S1 is extracted; in some embodiments, the vacuum holes 30 are distributed near the four corners and the center of the orthographic projection of the battery cell on the bearing surface S1, which is conducive to the uniform force on the battery cell.

[0052] In a preferred embodiment, the vacuum holes 30 include a plurality of vacuum holes 30, which are evenly distributed at intervals in the orthographic projection area of ​​the battery cell on the bearing surface S1.

[0053] This embodiment is beneficial to improving the efficiency of extracting air between the contact area of ​​the battery cell and the bearing surface S1. At the same time, the vacuum holes 30 are evenly distributed, which helps to ensure that the battery cell is subjected to uniform force and is stably limited on the bearing surface S1.

[0054] As an implementation method, one of the first limiting member and the second limiting member includes two adjusting blocks 12, which are disposed opposite to each other on the bearing surface S1 in a first direction.

[0055] The other of the first and second limiting members includes a stop bar 13, which is located on the bearing body 11 in the second direction and is disposed opposite to the shaping block 21.

[0056] It is understood that the first limiting member includes two adjusting blocks 12 arranged opposite to each other in the first direction, and the second limiting member includes a stop bar 13 arranged opposite to the shaping block 21 in the second direction;

[0057] In some embodiments, the first limiting member includes a stop bar 13 disposed opposite to the shaping block 21 in a second direction, and the second limiting member includes two adjusting blocks 12 disposed opposite to each other in a first direction.

[0058] In this embodiment, the first limiting member and the second limiting member have a simple structure, which is conducive to limiting the battery cell from two different directions and ensuring the stability of the battery cell position.

[0059] In a preferred embodiment, at least one of the two adjusting blocks 12 can be moved relative to the other along a first direction, either towards or away from it, to adjust the size of the accommodating space.

[0060] Understandably, one adjusting block 12 moves towards or away from another adjusting block 12 along the first direction, thereby increasing or decreasing the distance between the two adjusting blocks 12 in the first direction, which is used to adjust the size of the accommodating space; of course, the other adjusting block 12 can move towards or away from each other along the first direction at the same time, thereby increasing or decreasing the distance between the two adjusting blocks 12 in the first direction, which is used to adjust the size of the accommodating space.

[0061] In this embodiment, the size of the accommodating space can be reliably adjusted by moving the adjusting block 12, which is beneficial for compatibility with battery cells of various specifications and sizes.

[0062] As a feasible approach, such as Figure 3 As shown, a first limiting structure 14 is provided on one of the bearing surface S1 and the adjusting block 12, and a first adjusting structure 15 is provided on the other. The first limiting structure 14 and the first adjusting structure 15 cooperate to fix the position of the adjusting block 12 on the bearing surface S1.

[0063] The first limiting structure 14 may be, but is not limited to, a bolt, a fixing pin, etc., and the first adjusting structure 15 may be, but is not limited to, a groove, a waist-shaped hole, or a guide rail, etc.

[0064] In this embodiment, the first adjustment structure 15 and the first limiting structure 14 facilitate the movement of the adjustment block 12 along the first direction. At the same time, when the adjustment block 12 moves to the predetermined position, the first limiting structure 14 and the first adjustment structure 15 mutually limit and fix the position of the adjustment block 12, thereby facilitating the stabilization of the cell position.

[0065] As an implementation method, one of the supporting body 11 and the stop bar 13 is provided with a second limiting structure, and the other is provided with a second adjusting structure. The second limiting structure and the second adjusting structure cooperate to adjust and fix the stop bar 13 in a third direction. The third direction is a direction perpendicular to the supporting surface S1 and is perpendicular to the first direction and the second direction, respectively.

[0066] Similarly, the second limiting structure may be, but is not limited to, a bolt, a fixing pin, etc., and the second adjusting structure may be, but is not limited to, a groove, a waist-shaped hole, or a guide rail, etc.

[0067] In this embodiment, the second adjustment structure and the second limiting structure facilitate the movement of the stop bar 13 along the third direction. Simultaneously, when the stop bar 13 moves to a predetermined position, the second limiting structure and the second adjustment structure mutually limit and fix the position of the stop bar 13, thereby facilitating the adjustment of the accommodating space in the third direction (e.g., ...). Figure 1 The size of the Z-direction (i.e., the height direction) allows the space to accommodate cells of different thicknesses, improving the compatibility of the cell forming fixture.

[0068] In some other embodiments, the baffle 13 may also move toward or away from the shaping block 21 in a second direction to adjust the size of the accommodating space.

[0069] For example, a guide rail is installed on the side of the supporting body 11, the guide rail extends along the second direction, and a stop bar 13 is installed on the guide rail to enable the stop bar 13 to move along the second direction.

[0070] As an alternative implementation, the shaping unit 20 also includes a drive mechanism that is driven to the shaping block 21. In a second direction, the drive mechanism drives the shaping block 21 to move toward or away from the support body 11 to adjust the size of the accommodating space.

[0071] In some embodiments, the driving mechanism includes a driving member 23 and a transmission member drivenly connected to the driving member 23. The transmission member is drivenly connected to the shaping block 21. The driving member 23 drives the transmission member to move the shaping block 21 toward or away from the support body 11 to adjust the size of the accommodating space.

[0072] The driving component 23 may be, but is not limited to, a machine that can provide power, such as a drive motor or cylinder; the transmission component may be, but is not limited to, a connecting rod, a drive shaft, etc., and the embodiments of this application do not specifically limit this.

[0073] As an implementation method, the driving mechanism includes a driving member 23, a connecting plate 24 and a connecting shaft 25. The connecting plate 24 is drivenly connected to the driving member 23, and the connecting shaft 25 is connected to the connecting plate 24 and the shaping block 21 respectively. The shaping unit 20 also includes a buffer member 26. The buffer member 26 includes an elastic member sleeved on the connecting shaft 25, and the two ends of the elastic member in the deformation direction are in close contact with the shaping block 21 and the connecting plate 24 respectively.

[0074] The connecting plate 24 and the connecting shaft 25 can work together as transmission components. The connecting shaft 25 is used to connect the connecting plate 24 and the shaping block 21, thereby transmitting power to the shaping block 21 and driving the shaping block 21 to move. The buffer 26 is mainly used to prevent the shaping block 21 from causing mechanical damage to the battery cell during contact with the battery cell. The buffer 26 can be, but is not limited to, a spring, a rubber sleeve or a silicone sleeve, etc., which provides buffering force through elastic deformation, thereby avoiding damage to the battery cell.

[0075] The driving mechanism of this embodiment has a simple structure, which is conducive to driving the shaping block 21. At the same time, the buffer 26 provides a buffering force, which helps to stabilize and limit the battery cell while avoiding mechanical damage to the battery cell and ensuring the quality of the battery cell.

[0076] In some embodiments, the cell forming fixture further includes a fixing platform 1, on which the supporting body 11 and the shaping unit 20 are disposed;

[0077] As an optional solution, the shaping unit 20 also includes a fixing block 22, on which the driving mechanism is fixed. One of the fixing block 22 and the fixing platform 1 is provided with a third limiting structure 27, and the other is provided with a third adjusting structure 28. The third limiting structure 27 and the third adjusting structure 28 cooperate to realize the position adjustment and fixation of the driving mechanism in the second direction.

[0078] Understandably, the fixed platform 1 serves as the main support for the entire cell forming fixture and is used to install the clamping unit 10, the shaping unit 20, and the vacuum unit.

[0079] The fixing block 22 of the shaping unit 20 is used to fix the driving mechanism on the fixed platform 1; the third limiting structure 27 may be, but is not limited to, bolts or fixing pins; the third adjusting structure 28 may be, but is not limited to, grooves or limiting holes.

[0080] For example, a plurality of limiting holes are evenly spaced along the second direction on the fixed platform 1, and bolts are connected to the fixed block 22. After the drive mechanism moves to the predetermined position, the bolts are limited to the inside of the limiting holes, and the position of the drive mechanism is fixed.

[0081] The third adjustment structure 28 and the third limiting structure 27 in this embodiment facilitate the movement of the drive mechanism and the shaping block 21 along the second direction. At the same time, when the drive mechanism and the shaping block 21 move to the predetermined position, the third adjustment structure 28 and the third limiting structure 27 mutually limit each other, fixing the position of the drive mechanism. This allows for reliable adjustment of the accommodating space, compatibility with various sizes of battery cells, and ensures that the shaping block 21 reliably limits the battery cells.

[0082] In summary, the battery cell forming fixture of this application defines an adjustable accommodating space between the support body 11 of the clamping unit 10, the first limiting member, the second limiting member, and the shaping block 21 of the shaping unit 20. This facilitates compatibility with battery cells of various sizes, makes it convenient for forming and processing battery cells of various sizes, and thus reduces the processing cost of batteries. Furthermore, the shaping block 21 of the shaping unit 20, in conjunction with the clamping unit 10, facilitates the shaping of the battery cells, such as, but not limited to, folding and sealing the edges of the battery cells. In addition, the vacuum pipeline of the vacuum unit connects to the area where the battery cell contacts the support surface S1 of the support body 11. By venting the air between the battery cell and the support surface S1 of the support body 11, a negative pressure is generated. Under the action of the negative pressure, it helps to prevent the battery cell from shifting or deviating, stabilizes and fixes the position of the battery cell, avoids mechanical damage to the battery cell, ensures the forming quality of the battery cell, and thus improves the processing efficiency of the battery. The battery cell forming fixture of this utility model has a simple structure, is easy to process, and is convenient to operate.

[0083] Furthermore, the buffer 26 of the shaping unit 20 helps to provide buffering force and avoid mechanical damage to the battery cell; the drive mechanism of the shaping unit 20 can move toward or away from the support body 11 in the second direction, further improving the flexibility of the accommodation space adjustment.

[0084] Secondly, embodiments of this application provide a battery processing apparatus, including the cell forming fixture of the first aspect. It is understood that the battery processing apparatus of this application possesses all the features and advantages of the aforementioned cell forming fixture, which will not be repeated here. In summary, the battery processing apparatus of this application is beneficial for improving production efficiency and increasing yield.

[0085] The following specific embodiment will be used to illustrate the cell forming fixture of this application.

[0086] like Figure 1-4 As shown, the battery cell forming fixture includes a fixed platform 1, on which a clamping unit 10, a vacuum unit, and a shaping unit 20 are provided;

[0087] The clamping unit 10 includes a bearing body 11 fixed on the fixed platform 1. The bearing body 11 has a bearing surface S1. Two adjusting blocks 12 are arranged opposite each other on the bearing surface S1 in a first direction. The two adjusting blocks 12 can move along the first direction ( Figure 1 The two adjusting blocks 12 on the bearing surface S1 are spaced apart along the first direction and have multiple first adjusting holes. Each adjusting block 12 has a waist-shaped hole. A bolt is installed inside the waist-shaped hole. The bolt and the first adjusting hole limit each other to realize the position adjustment and fixation of the adjusting block 12. The first adjusting hole and the waist-shaped hole are equivalent to the first adjusting structure 15, and the bolt is equivalent to the first limiting structure 14.

[0088] The main body 11 in the second direction ( Figure 1 A stop bar 13 is provided on one side of the load-bearing body 11 in the X direction, and bolts are provided on the side of the stop bar 13 along the third direction ( Figure 1 An elongated hole is provided in the Z direction. The bolt passes through the elongated hole. After the stop bar 13 moves to the predetermined position, the position of the stop bar 13 is fixed by the cooperation of the nut and the bolt. The elongated hole is equivalent to the second adjustment structure, and the nut and the bolt are equivalent to the second limiting structure.

[0089] The vacuum unit on the support body 11 includes a vacuum pipeline, a vacuum hole 30 and a connector 31. The vacuum pipeline is located inside the support body 11. Multiple vacuum holes 30 are spaced apart on the support surface S1. The vacuum holes 30 are connected to one end of the vacuum pipeline. When the battery cell is located on the support surface S1, the battery cell completely covers the vacuum hole 30. The other end of the vacuum pipeline is connected to the connector 31, which is used to connect to external vacuum equipment.

[0090] The shaping unit 20 includes an L-shaped fixing block 22, a cylinder, a connecting plate 24, a connecting shaft 25, a buffer 26, and a shaping block 21, which is mounted on the fixing platform 1 along the second direction ( Figure 1 A second adjustment hole is provided at intervals in the X direction. Bolts and nuts are provided on the L-shaped fixing block 22. The cylinder is fixedly installed on the L-shaped fixing block 22. When the battery cell is located on the bearing surface S1, the L-shaped fixing block 22 is moved so that the cylinder drives the shaping block 21 to contact the side of the battery cell.
