[0017] 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.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present application will now be described in detail with reference to the embodiments.

[0019] Embodiments of this application provide a cell formation fixture 100, such as Figure 1-2 As shown, it includes: The clamping assembly 10 includes a connecting part and a clamping part, wherein the clamping part is rotatably connected to the connecting part so that the clamping part can rotate about the center of the connecting part; The first moving mechanism includes a first guide member 20 and a flipping assembly 50. The first guide member 20 extends along a first direction, and a connecting part is slidably connected to the first guide member 20 and can move along the extending direction of the first guide member 20. The flipping assembly 50 includes a drive motor 51, and the output shaft of the drive motor 51 is drivenly connected to the first guide member 20 to drive the first guide member 20 to rotate around the output shaft of the drive motor 51, so as to drive the clamping assembly 10 to flip to a predetermined angle.

[0020] It should be noted that the cell formation fixture of the embodiments of this application can be used independently to facilitate the clamping and movement of the cell to the processing station; of course, the cell formation fixture of the embodiments of this application can also be installed on the cell formation device. The cell formation fixture is installed on one side of the cell formation device to replace manual handling of the cell, which helps to reliably avoid problems such as tilting, misassembly, and omission that occur during manual handling. Through the clamping component 10 and the first moving mechanism, the production and processing efficiency is improved, and the consistency of the cell placement position can be guaranteed.

[0021] It is understood that the connecting part is slidably connected to the first guide member 20, so that the connecting part can drive the clamping part to move along the extension direction of the first guide member 20, thereby realizing the position adjustment of the clamping part; and the first guide member 20 rotates along the output shaft of the drive motor 51 under the drive of the drive motor 51, causing the connecting part and the clamping part to flip. Thus, it can be seen that the connecting part and the first guide member 20 are mutually limited in other directions except the first direction, and the connecting part and the first guide member 20 do not produce any relative movement in other directions. For example, the first guide member 20 is provided with a groove along the first direction, the connecting part is sleeved on the first guide member 20, and the connecting part includes a boss that cooperates with the groove. The boss and the groove are slidably engaged, so that while the connecting part moves along the first direction, it can be flipped to a predetermined angle under the rotation of the first guide member 20.

[0022] The first direction can be Figure 2In the X direction, when the clamping assembly 10 is mounted on the first guide member 20, the clamping part faces the vertical direction. Figure 2 In the Z direction), driven by the drive motor 51, the first guide member 20 rotates, causing the entire clamping assembly 10 to flip to the horizontal direction. Figure 2 (Y direction in the process). In actual processing, the cell formation fixture is installed in the direction of the cell formation device, with the clamping part vertically downward, which can accurately place the cell in the accommodating space of the formation zone 210; when the cell formation fixture is installed on one side of the formation zone 210 of the cell formation device in the horizontal direction, and the accommodating space of the formation zone 210 is arranged in the vertical direction, it is necessary to flip the clamping part to the horizontal direction.

[0023] It is also understood that the clamping part can be set according to the actual shape or size of the battery cell, such as, but not limited to, two clamping plates 12, as long as the battery cell is safely clamped; the first guide member 20 can be a slide rail or a long rod; the first moving mechanism can also include a driving member, which is drivenly connected to the clamping assembly 10 and is used to drive the clamping assembly 10 to move along the extension direction of the first guide member 20.

[0024] The cell formation fixture of this application solves the problem in related technologies that it is impossible to accurately adjust the position of the cell in multiple directions, resulting in poor versatility. In the embodiments of this application, the clamping assembly 10 includes a connecting part and a clamping part. The connecting part can rotate around its center, which facilitates the adjustment of the position of the clamping part, allowing it to be accurately aligned with the accommodating space of the formation area 210 of the cell formation device. Furthermore, the first moving mechanism includes a first guide member 20 and a flipping assembly 50. The first guide member 20 is provided to facilitate the adjustment of the position of the clamping part in a first direction. The flipping assembly 50 drives the first guide member 20 to rotate, allowing the clamping part to be flipped at any angle. This makes the cell formation fixture applicable to different types of formation devices, improving the versatility of the entire formation fixture.

[0025] In some embodiments, the output shaft of the drive motor 51 and the first guide member 20 are connected by a fixed flange 53.

[0026] In this embodiment, the first guide member 20 and the output shaft of the drive motor 51 are connected by the fixed flange 53, which is beneficial for the drive motor 51 to reliably drive the first guide member 20 to rotate.

[0027] As a feasible method, the cell formation fixture 100 also includes: The second moving mechanism includes a second guide 30, which extends along a second direction, and the clamping assembly 10 can move along the extension direction of the second guide 30; wherein the second direction is different from the first direction.

[0028] The second direction can be Figure 2 in the Y direction.

[0029] In some embodiments, the first guide member 20 is mounted on the second guide member 30, and the first guide member 20 can move along the extension direction of the second guide member 30, thereby driving the clamping assembly 10 to move along the extension direction of the second guide member 30.

[0030] In this embodiment, the second moving mechanism can adjust the position of the clamping component 10 in the second direction, further improving the flexibility of the position adjustment of the clamping component 10.

[0031] In some embodiments, the second guide member 30 includes two members, which are arranged parallel to each other. The first guide member 20 is disposed between the two second guide members 30, and the drive motor 51 is slidably connected to one of the second guide members 30 so that the first guide member 20 moves along the extension direction of the second guide member 30, thereby driving the clamping assembly 10 to move.

[0032] The second guide member 30 includes two members, and the first guide member 20 is disposed between the two second guide members 30, so that the first guide member 20 is connected to the second guide member 30 at both ends of the extension direction. This helps to ensure that the first guide member 20 moves stably along the second guide member 30, avoids shaking, avoids collision with the battery cell, and ensures the quality of the battery cell.

[0033] It is understandable that a mounting seat can be provided on the second guide member 30, the mounting seat is slidably connected to the second guide member 30, and the drive motor 51 is fixedly mounted on the mounting seat, thereby realizing the slidable connection between the drive motor 51 and the second guide member 30.

[0034] In some embodiments, the flipping assembly 50 further includes a toothed shaft 52, the extending direction of the toothed shaft 52 being parallel to the extending direction of the first guide member 20, the meshing portion of the toothed shaft 52 engaging with the other end of the first guide member 20, and one end of the toothed shaft 52 being slidably connected to another second guide member 30.

[0035] It is understood that the gear shaft 52 includes a body and a meshing part disposed on the body. The meshing part meshes with the first guide member 20 to accommodate the drive motor 51 driving the first guide member 20 to rotate.

[0036] In this embodiment, the gear shaft 52 ensures that the first guide member 20 can rotate reliably under the drive of the drive motor 51, thereby causing the clamping assembly 10 to flip. Furthermore, the gear shaft 52 also facilitates the sliding connection between the first guide member 20 and the second guide member 30, ensuring that the first guide member 20 moves stably along the second guide member 30.

[0037] As a feasible method, the cell formation fixture 100 also includes: The third moving mechanism includes a third guide 40, which extends along a third direction, and the clamping assembly 10 is movable along the extension direction of the third guide 40; wherein the third direction is different from the second direction.

[0038] Among them, the third party can be Figure 2 The Z direction in the equation.

[0039] In this embodiment, the third moving mechanism is provided to increase the degree of freedom of movement of the clamping component 10, so that the position of the clamping component 10 in the vertical direction can be flexibly adjusted to accommodate the space of the formation zone 210 at different heights.

[0040] In some embodiments, the first guide 20 and the second guide 30 are mutually limited in the third direction, so that the second guide 30 can move along the extension direction of the third guide 40, thereby driving the first guide 20 and the clamping assembly 10 as a whole to move along the extension direction of the third guide 40.

[0041] In some embodiments, the third guide member 40 includes at least two third guide members 40, which are correspondingly disposed at both ends of the extension direction of the second guide member 30, and the two third guide members 40 have at least two opposite sides with grooves 41 extending along the extension direction of the third guide member 40. The second guide member 30 has a boss 31 at each end of its extension direction. The boss 31 slides with the slide groove 41 so that the second guide member 30 can move along the extension direction of the third guide member 40, thereby driving the first guide member 20 and the clamping assembly 10 to move.

[0042] It is understandable that a third guide 40 is provided at both ends of the extension direction of each second guide 30, so that both ends of the extension direction of the second guide 30 are supported, which can ensure that the second guide 30 moves smoothly along the extension direction of the third guide 40.

[0043] The groove 41 of the third guide member 40 and the boss 31 of the second guide member 30 slide in the third direction, limiting each other in the first and second directions, ensuring that the second guide member 30 does not move in other directions while moving along the third guide member 40, thereby improving the smoothness of the movement of the second guide member 30.

[0044] It is also understandable that the first, second, and third moving mechanisms can each be equipped with driving components to provide power and achieve movement in different directions.

[0045] In some embodiments, such as Figures 3-5As shown, the connecting part includes a slider 13, a connecting shaft 14 and a turntable 15. The slider 13 is slidably connected to the first guide member 20. One end of the connecting shaft 14 is connected to the slider 13, and the other end of the connecting shaft 14 is rotatably connected to the turntable 15. The turntable 15 is connected to the clamping part.

[0046] A bearing can be installed between the turntable 15 and the connecting shaft 14 to ensure that the turntable 15 can rotate around the connecting shaft 14.

[0047] In this embodiment, the connecting part structure can be slidably connected with the first guide member 20, driving the clamping part to move along the extension direction of the first guide member 20. On the other hand, under the action of the turntable 15, the clamping part can rotate around the connecting shaft 14.

[0048] In some embodiments, such as Figure 4 and Figure 5 As shown, the clamping part includes a connecting plate 11 and two clamping plates 12, and the connecting plate 11 is connected to the turntable 15; Each of the two opposing sides of the connecting plate 11 has a locking platform 111 and a groove 112. Each clamping plate 12 has a first locking groove 121 and a second locking groove 122 that are interconnected. The first locking groove 121 extends from the end of the clamping plate 12 along the fourth direction, and the second locking groove 122 extends to the side wall of the first locking groove 121 along the fifth direction. The first locking groove 121 and the second locking groove 122 define an overlapping platform 123 on the clamping plate 12. The overlapping platform 123 is located in the groove 112. The locking platform 111 cooperates with the second locking groove, and the overlapping platform 123 can move along the extension direction of the groove 112 to adjust the distance between the two clamping plates 12. The fourth direction and the fifth direction are perpendicular.

[0049] It is understandable that the connecting plate 11, as the main support of the clamping part, is mainly used to install the clamping plate 12 and also to adjust the distance between the two clamping plates 12.

[0050] In some embodiments, the fourth direction can be understood as the length direction of the clamping plate, and the fifth direction can be the width direction of the clamping plate.

[0051] When the overlapping platform 123 of the two clamping plates 12 is located in the groove 112, the snap-fit ​​platform 111 of the connecting plate 11 is displaced into the second snap-fit ​​groove 122, thereby connecting the clamping plate 12 and the connecting plate 11. By moving the overlapping platform 123 of the two clamping plates 12 towards or away from each other along the extension direction of the groove 112, the distance between the two clamping plates 12 is reduced or increased.

[0052] In this embodiment, the structure of the connecting plate 11 and the clamping plate 12 is conducive to the stable connection of the clamping plate 12 to the connecting plate 11. At the same time, the distance between the two clamping plates 12 can be adjusted so that the clamping plate 12 can clamp battery cells of different sizes, thereby improving the versatility of the fixture.

[0053] In summary, the cell formation apparatus of the present application can adjust the position of the clamping component 10 in three directions, and the clamping component 10 can rotate and flip, which is beneficial to quickly and accurately position the workpiece to the required position, avoid the cumulative positioning difference caused by multiple clamping, and also avoid problems such as misplacement or omission caused by manual handling of the cell.

[0054] Secondly, this utility model provides a cell formation apparatus 200, such as... Figure 6 As shown, it includes: The formation zone 210 is provided with multiple accommodating cavities for accommodating battery cells; The first aspect is the cell formation fixture, which is disposed on one side of the formation zone 210.

[0055] It is understandable that this cell formation device possesses all the features and advantages of the aforementioned cell formation fixture, which will not be elaborated upon here. In summary, this cell formation device has high working efficiency, frees up manpower, and helps reduce labor costs.

[0056] In some embodiments, the cell formation apparatus further includes a control system (not shown in the figure), which is electrically connected to the first moving mechanism, the second moving mechanism and the third moving mechanism. Specifically, the control system is electrically connected to the driving members (not shown in the figure) corresponding to the first moving mechanism, the second moving mechanism and the third moving mechanism. The control system is used to control the clamping assembly 10 to move under the action of the first moving mechanism, the second moving mechanism and the third moving mechanism according to the pre-set stroke parameters of the clamping assembly 10, so as to ensure that the cell is accurately placed in the receiving cavity of the formation region 210.

The turntable 15 is connected to the connecting plate 11. Each of the two opposite sides of the connecting plate 11 forms a locking platform 111 and a groove 112. Each clamping plate 12 has a first locking groove 121 and a second locking groove 122 that are interconnected. The first locking groove 121 and the second locking groove 122 define an overlapping platform 123 on the clamping plate 12. The overlapping platform 123 is located in the groove 112. The locking platform 111 cooperates with the second locking groove, and the overlapping platform 123 can move along the extension direction of the groove 112 to adjust the distance between the two clamping plates 12. The cell formation apparatus 200 also includes a control system (not shown in the figure). The first moving mechanism, the second moving mechanism and the third moving mechanism are each connected to a driving component. The drive motor 51 and the driving component are electrically connected to the control system.
