[0047] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the scope of protection of the utility model.

[0048] like Figure 1 As shown, a battery cell stacking device includes:

[0049] Conveying mechanism 1 is used to convey battery cells;

[0050] The pre-stacking mechanism 5 is used to pre-stacking the multiple rows of battery cells conveyed on the conveying mechanism 1;

[0051] Transfer mechanism 2, located on one side of the conveying mechanism 1, is used to transfer pre-stacked battery cells;

[0052] Stacking mechanism 3, located on one side of transfer mechanism 2, is used to stack the transferred battery cells;

[0053] The stacking platform 4 is located below the stacking mechanism 3 and is used to receive the battery cells of the stacking mechanism 3.

[0054] This application enables automatic stacking of battery cells, stacking them to a designated position. The pre-stacking of multiple rows of battery cells conveyed on the conveying mechanism 1 can effectively improve the working efficiency of the subsequent transfer mechanism 2 and stacking mechanism 3, resulting in high working efficiency and meeting the inventor's stacking needs.

[0055] The conveying mechanism 1 used in this application can have many structural forms, such as a belt conveyor or a magnetic levitation conveyor. The specific structure of this application embodiment is not limited.

[0056] like Figure 2 and Figure 3 As shown, the pre-stacking mechanism 5 includes:

[0057] The first frame 51 is located above the conveying mechanism 1;

[0058] The first motion component is mounted on the first frame 51;

[0059] A first clamping assembly 52 is disposed on the first motion assembly, and the first motion assembly drives the first clamping assembly 52 to pre-stack the battery cells on the conveying mechanism 1.

[0060] Specifically, the first motion component is provided with at least one, the first motion component includes a first lateral movement module 53 and a first vertical movement module 54, the first lateral movement module 53 drives the first vertical movement module 54 to move laterally, and the first clamping component 52 is provided at the output end of the first vertical movement module 54; the conveying mechanism 1 conveys multiple rows of battery cells, and the first motion component drives the first clamping component 52 to pre-stack the multiple rows of battery cells on the conveying mechanism 1, so that one row of battery cells in two adjacent rows of battery cells is stacked on the other row of battery cells;

[0061] The first clamping assembly 52 includes a movable plate 521 and a fixed plate 522. Multiple first clamping plates 523 are distributed along the length of both the movable plate 521 and the fixed plate 522. A cylinder (not shown in the figure) pushes the movable plate 521 relative to the fixed plate 522 to clamp the battery cell. The assembly also includes second clamping plates 524 disposed at both ends of the movable plate 521 along its length. The movement direction of the second clamping plates 524 is cross-shaped with the movement direction of the movable plate 521. The two second clamping plates 524 move towards each other via a linear movement mechanism 525 to clamp and center the battery cell. The linear movement mechanism 525 can be a lead screw and nut mechanism, where the lead screw is a bidirectional lead screw. The two second clamping plates 524 are respectively screwed into two sections of thread on the lead screw. When the lead screw rotates, the two clamping plates move towards each other.

[0062] When the pre-stacking mechanism 5 is in operation, the moving plate 521 moves relative to the fixed plate 522, driving multiple first clamping plates 523 to clamp the battery cells. At the same time, the setting of the second clamping plate 524 and the linear moving mechanism 525 can ensure the alignment of the battery cells during clamping. On the one hand, it improves the alignment accuracy during clamping. On the other hand, after the battery cells are stacked, the first clamping plate 523 and the second clamping plate 524 can clamp and release the stacked battery cells from the side, so that the stacked battery cells are aligned.

[0063] like Figure 1 As shown, it also includes a buffer platform 6, which is located between the pre-stacking mechanism 5 and the stacking mechanism 3 and on one side of the conveying mechanism 1. When the stacking platform 4 is full, the transfer mechanism 2 buffers the battery cells onto the buffer platform 6. This design allows the conveying mechanism 1 to transport normally without stopping, and also allows the battery cells on the buffer platform 6 to satisfy the gripping of the transfer mechanism 2 when the conveying mechanism 1 stops or is idle (that is, when the conveying mechanism 1 transports the position without battery cells to the transfer mechanism 2), so that the transfer mechanism 2 and the subsequent stacking mechanism 3 do not stop.

[0064] like Figure 1 and Figure 4 As shown, the transfer mechanism 2 includes a second motion component 21 and a second clamping component 22. The second clamping component 22 is installed at the output end of the second motion component 21. The second motion component 21 drives the second clamping component 22 to transfer the battery cell to the stacking mechanism 3.

[0065] The second clamping assembly 22 includes a first drive assembly 222, a connecting frame 221, and a clamp 223;

[0066] The connecting frame 221 is installed at the output end of the second motion component 21;

[0067] The clamp 223 is provided in at least one set and is mounted on the connecting frame 221;

[0068] The first drive assembly 222 is mounted on the connecting frame 221 or the second motion assembly 21 to drive the clamp 223 to slide along the connecting frame 221.

[0069] In specific implementation, the second motion component 21 can be an industrial robot, and the clamp 223 is provided in two sets. The clamp 223 can be any type of gripper in the prior art, such as an electromagnetic opening and closing gripper or a pneumatic opening and closing gripper, without limitation. The first drive component 222 can be a cylinder, and the number of cylinders corresponds to the number of clamps 223. During operation, the first drive component 222 drives the corresponding clamp 223 to move on the connecting frame 221, finely adjusting the position of the clamp 223 relative to the battery cell to improve the gripping accuracy.

[0070] like Figure 1 , Figure 5 and Figure 6 As shown, the stacking mechanism 3 includes:

[0071] The second frame 31 is located on one side of the transfer mechanism 2;

[0072] The third motion component 32 is mounted on the second frame 31;

[0073] The third clamping component 33 is disposed on the third motion component 32. The third motion component 32 drives the third clamping component 33 to pick up the battery cell transferred by the transfer mechanism 2 and stack the battery cell onto the stacking platform 4.

[0074] The third clamping assembly 33 includes a second driving assembly, a first clamping member 331 and a second clamping member 332. The first clamping member 331 and the second clamping member 332 are respectively provided with clamping plates on their opposite sides. The two clamping plates of the first clamping member 331 and the two clamping plates of the second clamping member 332 are staggered. The second driving assembly drives the first clamping member 331 and the second clamping member 332 to move towards each other to clamp the battery cell synchronously.

[0075] The second drive assembly includes two vertically distributed and relatively parallel racks 334. One rack 334 is connected to two clamping plates in the first clamping member 331, and the other rack 334 is connected to two clamping plates in the second clamping member 332. It also includes a gear located between the two racks 334 and meshing synchronously with the two racks 334. A motor drives the gear to rotate (not shown in the figure), causing the first clamping member 331 and the second clamping member 332 to move towards each other. Of course, one rack 334 can also be fixed and the other rack 334 can mesh with the gear to achieve the same effect.

[0076] It also includes a vertical drive component 333, the third clamping assembly 33 is mounted on the third motion assembly 32 via the vertical drive component 333, and the vertical drive component 333 is used to drive the third clamping assembly 33 to move up and down.

[0077] In specific implementation, the third motion component 32 is the second horizontal movement module, and the vertical drive component 333 is the second vertical movement module. During operation, the transfer mechanism 2 clamps both ends of the battery cell through the clamp 223, and then the second motion component 21 transports the battery cell vertically to the stacking mechanism 3. At this time, the clamp 223 does not release the clamp on the battery cell. Then, the third motion component 32 and the vertical drive component 333 in the stacking mechanism 3 drive the third clamping component 33 to move to one side of the clamp 223, so that the clamping plates in the first clamping member 331 and the second clamping member 332 in the third clamping component 33 move to both sides of the vertical battery cell. Then, the second drive component drives the staggered clamping plates to move towards each other, clamping the battery cell from both sides of the vertical battery cell. After that, the clamp 223 releases the clamp and moves back, realizing the transfer of the battery cell. Of course, the transfer mechanism 2 can also place the battery on a platform and then be clamped by the stacking mechanism 3. The technical solution of this application adopts the former, which is faster.

[0078] Preferably, the device further includes multiple pressing and positioning components 335, which are disposed on the third clamping assembly 33 and press down on the top of the battery cell from top to bottom to pre-compress the battery cell during stacking. The pressing and positioning component 335 is a pneumatic telescopic cylinder fixed on the vertical moving component, and the telescopic end of the pneumatic telescopic cylinder is provided with a pressure block. When the stacking mechanism 3 stacks the battery cells, the pneumatic telescopic cylinder drives the pressure block to move downward to pre-compress the battery cell. Then, the first clamping component 331 and the second clamping component 332 release the clamping of the battery cell, and finally release the pre-compression of the battery cell, thereby ensuring the stability of the battery cell stacking and compacting the stacked battery cells together.

[0079] Preferably, the device further includes two sets of abutment plates 336, disposed on the third clamping assembly 33. The two sets of abutment plates 336 are respectively disposed between two pairs of clamping plates staggered in the first clamping member 331 and the second clamping member 332. They are used to abut against the side of the clamped battery cell corresponding to one side of the third clamping assembly 33 when clamping the battery cell, controlling the distance between the battery cell and the third clamping assembly 33 during clamping. Each abutment plate 336 consists of a first plate and a second plate. The first plate is connected to the third clamping assembly 33, and a spring is provided between the second plate and the first plate to abut against the side of the battery cell. During operation, the third clamping assembly 33 moves to one side of the clamp 223. The abutment plate 336 first contacts the side of the battery cell on the clamp 223, abutting against the side of the battery cell. Then, the third clamping assembly 33 clamps the battery cell on the clamp 223, ensuring the distance between the battery cell and the third clamping assembly 33 during clamping.

[0080] like Figure 5 As shown, the stacking mechanism 3 also includes a pressing component 34 mounted on the second frame 31, which is used to compact and bond the stacked cells.

[0081] Specifically, the pressing assembly 34 includes multiple vertical telescopic components and pressure plates disposed at the ends of each vertical telescopic component; during operation, the pressing assembly 34 is used to press the two ends of the battery cell from top to bottom to ensure the compaction of the stacked battery cells and ensure the stability of the battery cells.

[0082] The vertical telescopic component can be selected from existing pneumatic or electric telescopic components.

[0083] like Figure 1 As shown, the stacking platform 4 includes an AGV (Automated Guided Vehicle) and a BLOCK platform (module platform). The BLOCK platform is located on top of the AGV to support the stacked battery cells. The BLOCK platform is equipped with a pressure holding component.

[0084] The stacking mechanism 3 is provided with a snap-fit ​​component 35 that is connected to the pressure holding component. The pressure holding component is connected to the snap-fit ​​component 35 to keep the BLOCK platform and the stacking mechanism 3 stable.

[0085] Specifically, the pressure holding component has slots on both sides. The locking component 35 includes a third lateral movement module 351 and a telescopic locking block 352 adapted to the slot on the third lateral movement module 351. The third lateral movement module 351 drives the telescopic locking block 352 to move to the slot. Then the telescopic locking block 352 extends and locks into the slot, so that the BLOCK platform and the stacking mechanism 3 remain stable. After stacking is completed, the telescopic locking block 352 retracts and disengages from the slot. The BLOCK platform moves to the next station under the drive of the AGV trolley.

[0086] It should be noted that the specific structures of the above-mentioned horizontal and vertical moving modules are common knowledge to those skilled in the art. For example, they can be made using linear moving slides, telescopic cylinders, hydraulic telescopic cylinders, etc., which are common in the prior art. Therefore, their specific structures will not be described in detail here.

[0087] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0088] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0089] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions of "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the utility model.
