The term "and / or" as used herein includes all or any one of the associated listed items and all combinations.

[0052] like Figures 1 to 13As shown, the utility model relates to a stacking device having a first direction and a second direction intersecting each other, comprising a mounting platform 1, and a stacking platform 2, a pressing and fixing mechanism 3, a pressing and movable mechanism 4 and a pressing and power mechanism 5 all arranged on the mounting platform 1; in the first direction, the pressing and fixing mechanism 3 is arranged on one side of the stacking platform 2, and the pressing and movable mechanism 4 is arranged on the other side.

[0053] The pressing movable mechanism 4 includes a movable connecting seat 41 and a first imitation plate 42. The movable connecting seat 41 is arranged on the mounting platform 1 and is spaced apart from the stacking platform 2 in the first direction. The first imitation plate 42 is detachably connected to the side of the movable connecting seat 41 facing the stacking platform 2, and there are multiple first imitation plates 42 in the second direction.

[0054] The pressing and fixing mechanism 3 includes a fixed support seat 31 and a second profiling plate 32. The fixed support seat 31 is arranged on the mounting platform 1 and is spaced apart from the stacking platform 2 in the first direction. The second profiling plate 32 is detachably connected to the side of the fixed support seat 31 facing the stacking platform 2, and there are multiple second profiling plates 32 in the second direction, and the multiple second profiling plates 32 correspond one to one to the multiple first profiling plates 42.

[0055] The pressing power mechanism 5 is used to drive the movable connection seat 41 to move along a first direction, so that the first profiling plate 42 moves closer to or away from the second profiling plate 32 .

[0056] In the present invention, when the battery cell and the liquid cooling plate are squeezed and fixed, the battery cell and the liquid cooling plate are placed between the first profiling plate 42 and the second profiling plate 32, and then the pressing power mechanism 5 drives the movable connecting seat 41 to move along the first direction to allow the first profiling plate 42 to approach the second profiling plate 32, so that the first profiling plate 42 and the second profiling plate 32 jointly squeeze the battery cell and the liquid cooling plate to complete the squeezing and fixing of the battery cell and the liquid cooling plate. Then, the pressing power mechanism 5 drives the movable connecting seat 41 to move along the first direction to allow the first profiling plate 42 to move away from the second profiling plate 32, and then repeat the above work to stack multiple battery cells and liquid cooling plates layer by layer. At the same time, since the first profiling plate 42 is detachably connected to the side of the movable connecting seat 41 facing the stacking platform 2, and the second profiling plate 32 is detachably connected to the side of the fixed support seat 31 facing the stacking platform 2, the user can adaptively replace the first profiling plate 42 and the second profiling plate 32 according to the arrangement shape of the battery cells of the battery module and the shape of the liquid cooling plate, so as to complete the stacking of battery cells with various arrangement shapes and liquid cooling plates with various shapes. Therefore, the stacking equipment can adapt to the production of various battery modules and the update and iteration of battery modules, and has stronger compatibility.

[0057] In this embodiment, the movable connecting seat 41 includes a pressing movable block 411 and a pressing movable frame 412. There are two pressing movable blocks 411. The two pressing movable blocks 411 are arranged on the mounting platform 1 at intervals along the second direction. The pressing movable frame 412 is connected between the two pressing movable blocks 411. The first imitation plate 42 is arranged on the side of the pressing movable frame 412 facing the stacking platform 2. The pressing power mechanism 5 is used to drive the pressing movable block 411 to move along the first direction.

[0058] The pressing movable mechanism 4 also includes a battery cell side positioning assembly 413 and a liquid cooling plate positioning assembly 414; two battery cell side positioning assemblies 413 are provided, and the two battery cell side positioning assemblies 413 are respectively located at the two ends of the pressing movable frame 412 in the second direction; two liquid cooling plate positioning assemblies 414 are provided, and the two liquid cooling plate positioning assemblies 414 are respectively located at the two ends of the pressing movable frame 412 in the second direction.

[0059] By allowing the pressing power mechanism 5 to drive the two pressing movable blocks 411 to move along the first direction, the pressing movable frame 412 can be driven to move along the first direction, thereby driving the first profiling plate 42 to move along the first direction. At the same time, since the pressing movable mechanism 4 also includes a battery cell side positioning component 413 and a liquid cooling plate positioning component 414, the battery cell and the liquid cooling plate can be stably positioned and placed on the first profiling plate 42. When the pressing power mechanism 5 drives the first profiling plate 42 to move along the first direction, it can ensure that the battery cell and the liquid cooling plate move stably along the first direction, thereby ensuring that the battery cell and the liquid cooling plate are stacked smoothly, and ultimately ensuring the performance of the battery module.

[0060] Specifically, the battery cell side positioning assembly 413 includes a battery cell positioning block 4131 and a battery cell positioning driver 4132. The battery cell positioning block 4131 is connected to the output end of the battery cell positioning driver 4132. The battery cell positioning driver 4132 is connected to the side of the pressing movable frame 412 facing the stacking platform 2. The battery cell positioning driver 4132 is used to drive the battery cell positioning block 4131 to move along the second direction to abut against the side of the battery cell in the second direction. The battery cell positioning driver 4132 is a battery cell positioning drive cylinder, and can also be other linear drivers.

[0061] Therefore, when multiple battery cells are arranged and placed on the stacking platform 2 and attached to the first contour plate 42, the battery cell positioning driver 4132 drives the battery cell positioning block 4131 to abut against the side of the outermost battery cell, thereby preventing the battery cell from shifting during the stacking process, ensuring the smooth stacking work and ensuring the performance of the battery module.

[0062] The liquid cooling plate positioning assembly 414 includes a liquid cooling plate positioning pin 4141 and a liquid cooling plate positioning driver 4142. The liquid cooling plate positioning pin 4141 is connected to the output end of the liquid cooling plate positioning driver 4142. The liquid cooling plate positioning driver 4142 is connected to the side of the pressing movable frame 412 facing away from the stacking platform 2. The liquid cooling plate positioning driver 4142 is used to drive the liquid cooling plate positioning pin 4141 to move along the first direction so as to penetrate the fluid collector of the liquid cooling plate. The liquid cooling plate positioning driver 4142 is a liquid cooling plate positioning drive cylinder, and can also be other linear drivers.

[0063] During the stacking process of the battery cells and the liquid cooling plate, there is a distance between the liquid cooling plate and the pressing movable frame 412. Therefore, it is necessary to use the liquid cooling plate positioning drive member 4142 to drive the liquid cooling plate positioning pin 4141 to move along the first direction, so that the liquid cooling plate positioning pin 4141 can pass through the end of the liquid cooling plate to position the liquid cooling plate and ensure a smooth stacking process. At the same time, it should be noted that the battery cell positioning block 4131 needs to be provided with an avoidance position for avoiding the liquid cooling plate positioning pin 4141, so that the liquid cooling plate positioning pin 4141 and the battery cell positioning block 4131 will not interfere with each other.

[0064] In this embodiment, the movable connecting seat 41 also includes a first guide assembly 415, a pressure sensor 416, an elastic reset member 417 and a connecting block 418. The first guide assembly 415 is connected between the pressing movable block 411 and the pressing movable frame 412 to guide the pressing movable frame 412 to move in the first direction. The connecting block 418 is arranged on the side of the pressing movable block 411 facing away from the stacking platform 2, and is spaced apart from the pressing movable frame 412. The pressure sensor 416 is arranged on the side of the connecting block 418 facing the pressing movable frame 412 to detect the pressure applied by the pressing movable mechanism 4. The elastic reset member 417 is arranged between the connecting block 418 and the pressing movable frame 412 to push the pressing movable frame 412 to separate from the pressure sensor 416 when the pressing movable mechanism 4 is away from the pressing fixing mechanism 3.

[0065] The first guide assembly 415 is a combination of a guide rail and a guide block, or a combination of a guide shaft and a guide sleeve, to guide the pressing movable frame 412 in the first direction, so that the pressing movable frame 412 can stably drive the battery cells and the liquid cooling plate to perform stacking. At the same time, due to the provision of the pressure sensor 416, when the battery cells and the liquid cooling plate are squeezed and the pressing movable frame 412 is pressed against the pressure sensor 416, the pressure sensor 416 can detect the pressure of the pressing movable mechanism 4 when squeezing the battery cells and the liquid cooling plate, thereby monitoring the force of squeezing the battery cells and the liquid cooling plate to prevent damage to the battery cells and the liquid cooling plate when the pressure is too high. When the pressing movable mechanism 4 stops squeezing the battery cells and the liquid cooling plate and separates from the battery cells and the liquid cooling plate, the elastic reset member 417 can push the pressing movable frame 412 and the pressure sensor 416 to separate. The elastic reset member 417 can be a reset spring.

[0066] In this embodiment, the pressing mechanism 4 further includes a first suction cup mounting block 43 and a first vacuum suction cup 44 disposed on the first suction cup mounting block 43. A plurality of the first suction cup mounting block 43 and the first vacuum suction cup 44 are provided, and the first suction cup mounting block 43 is detachably connected to the first contour plate 42.

[0067] By setting the first suction cup mounting block 43 and the first vacuum suction cup 44, the battery cell can be firmly sucked so that the battery cell is firmly attached to the side of the first suction cup mounting block 43 facing the stacking platform 2, so as to ensure the stability of the battery cell arrangement position, thereby ensuring the smooth subsequent battery cell and liquid cooling plate stacking work.

[0068] In this embodiment, the stacking device further includes a liquid cooling plate clamping mechanism 6 provided on the mounting platform 1 , and the liquid cooling plate clamping mechanism 6 includes a first clamping jaw 61 , a first clamping drive assembly 62 , a second clamping jaw 63 and a second clamping drive assembly 64 .

[0069] The pressing movable frame 412 is opposite to one side of the stacking platform 2 and is provided with the first clamping drive component 62 and the first clamping jaw 61 at both ends in the second direction. The first clamping jaw 61 is connected to the output end of the first clamping drive component 62. The first clamping drive component 62 can be a clamping cylinder, so as to drive the first clamping jaw 61 to clamp on the end of the liquid cooling plate.

[0070] The stacking platform 2 is provided with a second clamping jaw 63 and a second clamping drive assembly 64 on both sides in the second direction, and the second clamping jaw 63 and the second clamping drive assembly 64 are spaced apart from the stacking platform 2. The second clamping jaw 63 is connected to the output end of the second clamping drive assembly 64. The second clamping drive assembly 64 can also be a clamping cylinder, which can drive the second clamping jaw 63 to clamp onto the end of the liquid cooling plate.

[0071] The pressing power mechanism 5 is also used to drive the second clamping drive assembly 64 to move along the first direction.

[0072] During the stacking process of the battery cells and the liquid cooling plates, the liquid cooling plates to be stacked are located on the stacking platform 2 and close to the side of the battery cells at the first contour plate 42. The first clamping drive assembly 62 can drive the first clamping claw 61 to clamp the end of the liquid cooling plate to be stacked, so as to ensure the stability of the movement of the liquid cooling plate when the pressing movable mechanism 4 pushes the liquid cooling plate to move along the first direction. When stacking, the second clamping drive assembly 64 can drive the second clamping claw 63 to clamp the end of the liquid cooling plate that has been stacked the previous time, so as to ensure that the liquid cooling plate will not shift during stacking and squeezing, thereby ensuring the performance of the battery module; at the same time, the pressing power mechanism 5 can drive the second clamping drive assembly 64 to move in the first direction, so as to adapt to and adjust the position of the second clamping drive assembly 64 as the stacking progresses, so as to fix the liquid cooling plates one by one, thereby ensuring the smooth stacking work.

[0073] In this embodiment, two pressing power mechanisms 5 are provided; the two pressing power mechanisms 5 are respectively located on both sides of the stacking platform 2 in the second direction and are spaced apart from the stacking platform 2 .

[0074] The pressing power mechanism 5 includes a second guide assembly 51, a first linear drive assembly 52 and a second linear drive assembly 53, all of which are arranged on the mounting platform 1. The second guide assembly 51 is used to guide the pressing movable block 411 and the liquid cooling plate clamping mechanism 6 to move in the first direction. The first linear drive assembly 52 is used to drive the pressing movable block 411 to move along the first direction. The second linear drive assembly 53 is used to drive the second clamping drive assembly 64 to move along the first direction.

[0075] The second guide assembly 51 includes a slide rail 511, a first slider 512 and a second slider 513. The slide rail 511 is arranged on the mounting platform 1 and extends along the first direction. The first slider 512 and the second slider 513 are both slidably connected to the slide rail 511. The pressing movable block 411 is connected to the first slider 512, and the second clamping drive assembly 64 is connected to the second slider 513.

[0076] Therefore, by providing the second guide assembly 51 , the pressing movable block 411 and the liquid cooling plate clamping mechanism 6 can stably move along the first direction, ensuring smooth stacking of the battery cells and the liquid cooling plate.

[0077] The first linear drive assembly 52 includes a first servo motor 521, a first ball screw 522, a first ball nut 523 and a first fixed seat 524. The first fixed seat 524 is fixed on the mounting platform 1 and two are spaced apart along the first direction. The two ends of the first ball screw 522 are respectively connected to the two first fixed seats 524. The first ball nut 523 is connected to the first ball screw 522. The first ball nut 523 is connected to the pressing movable block 411. The first servo motor 521 is used to drive the first ball screw 522 to rotate.

[0078] Therefore, the first servo motor 521 can drive the first ball screw 522 to rotate, so that the first ball nut 523 moves along the axial direction of the first ball screw 522 , so that the pressing movable block 411 can move stably along the first direction.

[0079] The second linear drive assembly 53 includes a second servo motor 531, a second ball screw 532, a second ball nut 533, a second fixed seat 534 and a movable seat 535.
