Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0049] Please see Figure 1 The battery cell stacking device provided in the embodiments of this application will now be described. The battery cell stacking device provided in the embodiments of this application can be used to stack at least two battery cells. The battery cell stacking device includes a support mechanism 10, a reference base 20, a movable base 30, a side pressing mechanism 40, and an end face pressing mechanism 50.

[0050] At least two battery cells can be placed sequentially on the support mechanism 10 along the first direction, that is, the support mechanism 10 can provide support for each battery cell.

[0051] The reference seat 20 is located on one side of the support mechanism 10 and can provide a reference limiting surface when the end face pressing mechanism 50 is pressing.

[0052] The movable seat 30 is located on the side of the support mechanism 10 away from the reference seat 20, and can be moved relative to the support mechanism 10 in a first direction. That is, the movable seat 30 is movable and can move relative to the support mechanism 10 in a first direction.

[0053] The side clamping mechanism 40 includes a first clamping component 41 and a second clamping component 42 arranged opposite to each other along a second direction. The first clamping component 41 and the second clamping component 42 are movably mounted on the movable seat 30 along the second direction to clamp the opposite sides of each battery cell along the second direction. By clamping the opposite sides of the battery cell along the second direction using the side clamping mechanism 40, the battery cell can be shaped along the second direction.

[0054] The end face pressing mechanism 50 is movably mounted on the movable base 30 along the first direction. During the movement of the movable base 30 along the first direction, the end face pressing mechanism 50 abuts against one side of the battery cell so that the other side of the battery cell abuts against the reference base 20. By pushing the battery cell along the first direction through the end face pressing mechanism 50, the sequentially placed battery cells are shaped along the first direction.

[0055] The first direction and the second direction are set at an angle. For details, please refer to [link / reference needed]. Figure 1The "first direction" can be represented by the X-axis in the diagram, the "second direction" by the Y-axis, and the "third direction" by the Z-axis. The first and second directions can be set at a 90° angle. Of course, the angle between the first and second directions can also be set according to actual needs, such as 45° or 150°.

[0056] The working principle of the cell stacking device in this application embodiment is as follows:

[0057] First, the first battery cell is placed on the support mechanism 10. Since the movable seat 30 can move along the first direction, the movable seat 30 drives the side pressing mechanism 40 and the end pressing mechanism 50 to move synchronously along the first direction.

[0058] When the side pressing mechanism 40 is directly facing the battery cell, the movable seat 30 stops moving. At this time, the first clamping component 41 and the second clamping component 42 can move closer to each other along the second direction to press the battery cell on both sides along the second direction, thereby shaping the first battery cell along the second direction. After the shaping is completed, the first clamping component 41 and the second clamping component 42 move further apart along the second direction to release the battery cell.

[0059] Next, the second battery cell is inserted, and the movement of the movable seat 30 along the first direction drives the side pressing mechanism 40 to move along the first direction, so that the side pressing mechanism 40 is directly facing the second battery cell.

[0060] When the side clamping mechanism 40 is facing the second battery cell, the movable seat 30 stops moving. At this time, the first clamping component 41 and the second clamping component 42 can move closer to each other along the second direction to clamp the opposite sides of the second battery cell along the second direction, thereby shaping the second battery cell along the second direction. After the shaping is completed, the first clamping component 41 and the second clamping component 42 move further apart along the second direction to release the second battery cell.

[0061] Repeat the above steps until all cells have been shaped along the second direction;

[0062] Finally, as the movable seat 30 moves along the first direction, it drives the end face pressing mechanism 50 to move along the first direction, so that the end face pressing mechanism 50 abuts against one side of the battery cell to push each battery cell to move synchronously along the first direction, so that the other side of the battery cell abuts against the reference seat 20, thereby realizing the shaping of each battery cell after stacking along the first direction.

[0063] The battery cell stacking device provided in this application embodiment includes a side clamping mechanism 40 comprising a first clamping component 41 and a second clamping component 42 disposed opposite to each other along a second direction. The first clamping component 41 and the second clamping component 42 are movably disposed on a movable seat 30 along the second direction. The movable seat 30 is movable relative to the support mechanism 10 along a first direction. The movable seat 30 drives the first clamping component 41 and the second clamping component 42 to move along the first direction, thereby sequentially clamping the opposite sides of each battery cell along the second direction, achieving the shaping of each battery cell along the second direction. In conjunction with this, an end face clamping mechanism 50 is movably disposed on the movable seat 30 along the first direction. After each battery cell has been shaped along the second direction, the movable seat 30 drives the end face clamping mechanism 50 to move along the first direction, so that the end face clamping mechanism 50 abuts against one side of the battery cell. During the movement of the movable seat 30 along the first direction, the other side of the battery cell abuts against the reference seat 20, achieving the shaping of the stacked battery cells along the first direction. Since the movable seat 30 can drive the side pressing mechanism 40 and the end pressing mechanism 50 to move along the first direction, the battery cell stacking device of this application embodiment can be applied to the shaping of different numbers of battery cells, thereby improving the versatility of the device.

[0064] Please see Figure 2 The first clamping assembly 41 and the second clamping assembly 42 may include a mounting member 411, a connecting member 412, and a clamping member 413. The mounting member 411 is disposed on the movable seat 30. One end of the connecting member 412 is disposed on the mounting member 411. The clamping member 413 is disposed on the other end of the connecting member 412. The two clamping members 413 clamp the battery cell on both sides along the second direction, thereby achieving clamping and positioning of the battery cell along the second direction.

[0065] Please see Figure 2 The side clamping mechanism 40 may further include a first driving member 43. The first driving member 43 is disposed on the movable seat 30. The first clamping assembly 41 and the second clamping assembly 42 are spaced apart on the first driving member 43 along the second direction. The first driving member 43 drives the first clamping assembly 41 and the second clamping assembly 42 to move closer to each other along the second direction to clamp the opposite sides of the battery cell along the second direction. By driving the first clamping assembly 41 and the second clamping assembly 42 to move closer to each other along the second direction by the first driving member 43, the opposite sides of the battery cell along the second direction are clamped, thereby achieving the shaping of the battery cell along the second direction. Specifically, the first driving member 43 may be a linear cylinder, a linear motor, or a rotary motor, and may be equipped with a transmission mechanism that can convert the rotational driving force of the rotary motor into the linear motion of the first clamping assembly 41 and the second clamping assembly 42, such as a gear rack or a lead screw and nut.

[0066] Please see Figure 3The end-face pressing mechanism 50 may include a pushing member 51 and a second driving member 52. The second driving member 52 is disposed on the movable seat 30, and the pushing member 51 is pulsatorically connected to the second driving member 52. The second driving member 52 drives the pushing member 51 to move along a first direction to abut against the battery cell. By driving the pushing member 51 to move along the first direction, the pushing member 51 can abut against the battery cell. Specifically, the second driving member 52 may be a linear cylinder, a linear motor, or a rotary motor, and may be equipped with a transmission mechanism that converts the rotational driving force of the rotary motor into the linear motion of the pushing member 51, such as a gear rack or a lead screw and nut.

[0067] It is understandable that the end face pressing mechanism 50 is not limited to this configuration. For example, the end face pressing mechanism 50 can also be configured as a pusher 51 and an adjusting screw structure, in which the pusher 51 moves along the first direction by rotating the screw.

[0068] Alternatively, the end face pressing mechanism 50 can also be configured as an abutment, which is directly driven by the movable seat 30 to abut or separate from the battery cell.

[0069] Please see Figure 3 The side of the pusher 51 that contacts the battery cell may have a flexible layer (not shown in the figure). The flexible layer can prevent damage to the battery cell.

[0070] Please see Figure 1 and Figure 4 The battery cell stacking device may further include a third drive member 60 and a terminal clamping member 70. The third drive member 60 is disposed on the movable seat 30. The terminal clamping member 70 is disposed on the third drive member 60. The third drive member 60 drives the terminal clamping member 70 to move in a third direction to abut against the terminal of the battery cell. When it is necessary to position the terminal of the battery cell, the third drive member 60 can drive the terminal clamping member 70 to move in a third direction so that the terminal clamping member 70 abuts against the terminal of the battery cell, thereby achieving the clamping and positioning of the battery cell terminal. Specifically, the third drive member 60 can be a linear cylinder, a linear motor, or a rotary motor, and is equipped with a transmission mechanism that can convert the rotational driving force of the rotary motor into the linear motion of the terminal clamping member 70, such as a gear rack or a lead screw and nut.

[0071] The third direction is set at an angle to the first and second directions. The third direction can be set at 90° to the first and second directions, or it can be set according to actual needs, such as 45° or 150°.

[0072] Please see Figure 1 and Figure 4The cell stacking device may further include a fourth driving member 80. The fourth driving member 80 is disposed on the movable base 30, and the third driving member 60 is disposed on the fourth driving member 80. The fourth driving member 80 can drive the third driving member 60 to move along a first direction. By configuring the fourth driving member 80, the third driving member 60 can be driven to move along the first direction, thereby driving the electrode clamping member 70 to move along the first direction. This allows adjustment of the position of the electrode clamping member 70, ensuring that the electrode clamping member 70 is aligned with the electrode of the cell, thus making it suitable for cells of different sizes and broadening its applicability.

[0073] Please see Figure 1 and Figure 3 The movable base 30 may include a movable plate 31 and a mounting base 32. The movable plate 31 is located below the support mechanism 10. The mounting base 32 is located on the movable plate 31, and the end face pressing mechanism 50 is located on the mounting base 32, with the end face pressing mechanism 50 located above the support mechanism 10. Its structure is simple and compact, saving space.

[0074] Please see Figure 3 The mounting base 32 may include a mounting plate 321 and two vertical plates 322. One end of each of the two vertical plates 322 is spaced apart on the movable plate 31 along a second direction. One end of the mounting plate 321 is connected to one of the vertical plates 322, and the other end of the mounting plate 321 is connected to the other vertical plate 322. An end-face pressing mechanism 50 is mounted on the mounting plate 321. That is, the mounting plate 321 and the vertical plates 322 form a U-shaped structure, which facilitates the installation of the end-face pressing mechanism 50.

[0075] Please see Figure 5 The support mechanism 10 may include two fixed seats 11, a support plate 12, and a support member 13. The two fixed seats 11 are spaced apart along a first direction. One end of the support plate 12 is connected to one of the fixed seats 11, and the other end is connected to the other fixed seat 11. A reference seat 20 is disposed on one side of the support plate 12 along the first direction. The support member 13 is disposed on the support plate 12, and each battery cell is placed sequentially on the support member 13 along the first direction. By setting up the support mechanism 10, a support surface can be provided for the battery cell stacking, improving the stacking stability and thus improving the compression and shaping effect.

[0076] The operation of the cell stacking device in one specific embodiment of this application is as follows:

[0077] First, the first battery cell is placed on the support mechanism 10. Since the movable seat 30 can move along the first direction, the movable seat 30 drives the third driving member 60, the side pressing mechanism 40 and the end pressing mechanism 50 to move synchronously along the first direction.

[0078] When the side pressing mechanism 40 is directly facing the battery cell, the movable seat 30 stops moving. At this time, the third driving member 60 can drive the electrode pressing member 70 to press the electrode of the battery cell to achieve the shaping of the battery cell electrode.

[0079] Next, the first clamping assembly 41 and the second clamping assembly 42 move closer to each other along the second direction to press the opposite sides of the battery cell along the second direction, thereby shaping the battery cell along the second direction. After the shaping is completed, the terminal post clamping member 70 and the side clamping mechanism 40 release the battery cell.

[0080] Next, the second battery cell is inserted, and the movement of the movable seat 30 along the first direction drives the third drive member 60 and the side pressing mechanism 40 to move along the first direction, so that the pole pressing member 70 and the side pressing mechanism 40 are directly facing the second battery cell.

[0081] When the side clamping mechanism 40 is directly opposite the second battery cell, the movable seat 30 stops moving. At this time, the third driving member 60 can drive the pole clamping member 70 to press against the pole of the second battery cell to achieve the shaping of the pole of the second battery cell. The first clamping assembly 41 and the second clamping assembly 42 move closer to each other along the second direction to clamp the opposite sides of the second battery cell along the second direction, thereby achieving the shaping of the second battery cell along the second direction. After the shaping is completed, the pole clamping member 70 and the side clamping mechanism 40 release the second battery cell.

[0082] Repeat the above steps until all cells are shaped in the second direction and the third direction upwards;

[0083] Finally, as the movable seat 30 moves along the first direction, it drives the end face pressing mechanism 50 to move along the first direction, so that the end face pressing mechanism 50 abuts against one side of the battery cell to push each battery cell to move synchronously along the first direction, so that the other side of the battery cell abuts against the reference seat 20, thereby realizing the shaping of each battery cell after stacking along the first direction.

[0084] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
