Description

Pre-stacking device and battery processing equipment Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a pre-stacking device and battery processing equipment. Background Art

[0002] During the battery production process, multiple battery cells need to be pre-stacked and then assembled to form a battery module or battery.

[0003] However, during the current pre-stacking process of battery cells, the battery cells are prone to tilting, resulting in low efficiency of the pre-stacking process. In severe cases, this may affect the structural stability of the battery module or battery formed by subsequent assembly.

[0004] Summary of the Invention

[0005] Based on this, the present application provides a pre-stacking device and battery processing equipment.

[0006] In a first aspect, the present application provides a pre-stacking device, comprising:

[0007] A mounting seat, the mounting seat having a pre-stack position and a pressurizing position;

[0008] A tray is provided on the mounting base, and is used to carry at least two battery cells, with each battery cell arranged along its own thickness direction;

[0009] A first clamping assembly is provided on the tray and is used to clamp each battery cell on the tray;

[0010] a second clamping assembly disposed at the pressurizing position and configured to be spaced apart from the first clamping assembly along the height direction of the battery cells when the tray moves from the pre-stacking position to the pressurizing position, and used to clamp each battery cell on the tray; and

[0011] The pushing assembly is movably arranged at the pressurizing position along the arrangement direction of the battery cells, and is used to push the battery cells on the tray in the pressurizing position to fit together.

[0012] In the technical solution of the embodiment of the present application, in the process of pushing the battery cells on the tray to fit together, the first clamping assembly and the second clamping assembly can be spaced apart from each other along the height direction of the battery cell, and at the same time clamp and fix the opposite ends of the battery cell in the height direction, thereby balancing the friction between the battery cell and its supporting surface, making the pre-stacking process of the battery cell smoother and reducing the probability of the battery cell falling over during the pre-stacking process.

[0013] In some embodiments, the second clamping assembly is movably disposed on the mounting base along a height direction of the battery cell.

[0014] In the technical solution of the embodiment of the present application, the second clamping assembly is movable in the height direction of the battery cell, so that the second clamping assembly can smoothly clamp the battery cell when the battery cell moves to the pressurizing position, and does not affect the battery cell following the movement of the tray under other circumstances, thereby enabling the battery cell to smoothly move between the pre-stacking position and the pressurizing position.

[0015] In some embodiments, the first clamping assembly and the second clamping assembly each include a first clamping member and a second clamping member respectively arranged on both sides of the tray along the width direction of the battery cell, and at least one of the first clamping member and the second clamping member is configured to be movably arranged along the width direction of the battery cell.

[0020] In some embodiments, the second clamping assembly further includes a limiting assembly disposed on the main body and located between the first clamping member and the second clamping member, the limiting assembly being configured to press each battery cell on the tray along a height direction of the battery cell.

[0021] In the technical solution of the embodiment of the present application, when the first and second clamping members clamp the upper sides of the battery cells along their width, the limiting assembly is located between the first and second clamping members and can press downward on the battery cells, stably supporting the battery cells on the support surface of the tray. This ensures greater stability of the battery cells during the pre-stacking process.

[0022] In some embodiments, the limiting assembly includes a telescopic member and a pressing member. The telescopic member is telescopically connected between the main body and the pressing member along the height direction of the battery cell. The pressing member is used to press each battery cell on the tray along the height direction of the battery cell.

[0023] In the technical solution of the embodiment of the present application, by providing a telescopic member and a pressing member, the battery cell can be pressed against the tray more stably, so that the battery cell can maintain balance during the process of pushing the battery cell.

[0025] In the technical solution of the embodiment of the present application, by providing a rolling portion, the pressing member can achieve rolling pressing against the battery cells, and can continuously apply pressing force when the battery cells move closer to each other along the arrangement direction, making the pressing process more stable.

[0026] In some embodiments, the pushing assembly includes a supporting member and a pushing member, the supporting member is arranged on the tray, the pushing member is movably arranged on the mounting seat along the arrangement direction of the battery cells, and the supporting member and the pushing member are respectively located on both sides of the tray along the arrangement direction of the battery cells, and the pushing member is configured to push each battery cell on the tray against the supporting member along the arrangement direction of the battery cells.

[0027] In the technical solution of the embodiment of the present application, through the mutual cooperation between the abutting member and the pushing member, the pre-stacking of multiple battery cells can be smoothly achieved, so that the battery cells are tightly fitted along their arrangement direction to facilitate subsequent assembly.

[0028] In some embodiments, the mounting base includes a base and a support member rotatably disposed on the base, the support member having a pressurizing position and at least two pre-stacking positions spaced apart along its circumference, each pre-stacking position correspondingly provided with a tray and a first clamping assembly; the second clamping assembly and the pushing assembly are both disposed at the pressurizing position;

[0029] Among them, the second clamping assembly is configured to clamp each battery cell on the tray along the width direction of the battery cell when one of the trays rotates to the pressurizing position; the pushing assembly is configured to perform a pushing operation on each battery cell on the tray when one of the trays rotates to the pressurizing position.

[0030] In the technical solution of the embodiment of the present application, by providing support members, battery cells can be stacked synchronously on multiple pre-stacking positions and rotated to pressurizing positions in sequence for pressurization, thereby improving the efficiency of the battery cell pre-stacking process.

[0049] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric vehicles, as well as in other fields. As the application of power batteries continues to expand, market demand is also growing.

[0050] A battery cell is the smallest unit that makes up a battery. Specifically, multiple battery cells can be connected in series, parallel, or in a hybrid configuration to form a battery module. One or more battery modules are then connected and assembled to form a battery. Of course, multiple battery cells can also be directly assembled to form a battery. Hybrid configuration refers to multiple battery cells connected both in series and in parallel.

[0051] In the process of assembling a battery module or battery using battery cells, it is usually necessary to apply glue to the surface of the battery cells, then pre-stack multiple battery cells in the thickness direction, apply pressure to the battery cells so that the battery cells can fit tightly together, and then use the adhesive tape on the surface of adjacent battery cells to achieve gluing and fixing.

[0052] When applying pressure to battery cells, friction is generated between them and their supporting surfaces. Furthermore, battery cell specifications may vary from batch to batch, resulting in varying heights. Consequently, when the battery cells are pressed together, friction between them and their supporting surfaces can easily cause them to tilt, impacting the efficiency of the pre-stacking process and even the structural stability of the battery module or battery formed from the assembled cells.

[0053] Based on the above considerations, in order to solve the problem that the current battery monomers have poor stability and are prone to tilting during the pre-stacking process, a pre-stacking device is provided in one or more embodiments of the present application, in which the battery monomers are clamped and fixed on the tray by a first clamping assembly, and the battery monomers on the tray can follow the tray to move from the pre-stacking position to the pressurizing position, and then the second clamping assembly is spaced from the first clamping assembly at the pressurizing position and double-clamps the battery monomers on the tray; thereby, the first clamping assembly and the second clamping assembly respectively clamp and fix the two ends of the battery monomer along the height direction of the battery monomer, and when the pushing assembly pushes the battery monomers to fit together, the friction between the battery monomer and its supporting surface can be balanced, so that the battery monomer remains balanced during the pressurization process, reducing the probability of the battery monomer tilting.

[0054] Referring to Figures 1 and 2, according to one or more embodiments, the present application provides a pre-stacking device 100, comprising a mounting base 10, a tray 20, a first clamping assembly 30, a second clamping assembly 40, and a pushing assembly 50. The mounting base 10 has a pre-stacking position 11 and a pressing position 12. The tray 20 is mounted on the mounting base 10 and is configured to carry at least two battery cells, with each battery cell arranged along its thickness. The first clamping assembly 30 is mounted on the tray 20 and is configured to clamp each battery cell on the tray 20. The second clamping assembly 40 is mounted on the pressing position 12 and is configured to be spaced apart from the first clamping assembly 30 along the height direction of the battery cells when the tray 20 moves from the pre-stacking position 11 to the pressing position 12. The second clamping assembly 40 is configured to clamp each battery cell on the tray 20. The pushing assembly 50 is movably mounted on the pressing position 12 along the direction in which the battery cells are arranged, and is configured to push the battery cells on the tray 20 into contact with each other in the pressing position 12.

[0055] It should be noted that the mounting base 10 refers to a structure that can provide an installation base for the tray 20, the second clamping assembly 40, and the pushing assembly 50. The pre-stacking position 11 refers to a station on the mounting base 10 for stacking multiple battery cells. Specifically, the battery cells are moved from the previous process to the pre-stacking position 11, and the multiple battery cells are stacked in sequence along the thickness direction at the pre-stacking position 11 to achieve preliminary stacking of the battery cells. The pressurizing position 12 refers to a station on the mounting base 10 for pressurizing the preliminarily stacked battery cells so that the multiple battery cells can fit tightly together. The pre-stacking position 11 and the pressurizing position 12 can be converted to each other by rotating or moving the mounting base 10 or other movement methods. For example, by rotating the mounting base 10, the tray 20 can be moved from the pre-stacking position 11 to the pressurizing position 12, or the tray 20 can be moved from the pressurizing position 12 to the pre-stacking position 11.

[0056] The tray 20 is a structure mounted on the mounting base 10 that supports and provides space for stacking at least two battery cells. Multiple battery cells can be arranged sequentially along their thickness on the tray 20. When the battery cells are supported on the tray 20, the first clamping assembly 30 can clamp and secure the battery cells on the tray 20 along their width, ensuring a stable placement on the tray 20.

[0057] The second clamping assembly 40 is positioned at the pressurizing position 12. When the tray 20 moves from the pre-stacking position 11 to the pressurizing position 12, the second clamping assembly 40 is spaced apart from the first clamping assembly 30 at the pressurizing position 12 along the height of the battery cells. Thus, the second clamping assembly 40 can clamp the battery cells on the tray 20 along the width of the battery cells at the pressurizing position 12. At this point, the first clamping assembly 30 and the second clamping assembly 40 respectively clamp the ends of the battery cells along the height of the battery cells. When the pushing assembly 50 applies pressure to the battery cells, the friction between the battery cells and their supporting surface is balanced, thereby maintaining the balance of the battery cells and reducing the probability of the battery cells tipping over during the pressurization process.

[0058] Furthermore, when the battery cells are stacked in the pre-stacking position 11, the poles are usually arranged upward. In this case, the height direction of the battery cell refers to the direction from the side surface where the poles are arranged to the other side surface opposite thereto. The width direction of the battery cell refers to the direction perpendicular to the height direction of the battery cell and parallel to the large surface of the battery cell. The thickness direction of the battery cell refers to the direction perpendicular to the large surface of the battery cell. Among them, the large surface of the battery cell generally refers to the side surface with the largest area on the battery cell.

[0059] In addition, the number of first clamping components 30 and second clamping components 40 is set to at least one, and the specific number can be adjusted according to the needs during actual use, so that multiple groups of battery cells can be stacked, and each first clamping component 30 is matched with a second clamping component 40, which will not be elaborated here.

[0060] Through the above structure, in the process of pushing the battery cells on the tray 20 to fit together, the first clamping assembly 30 and the second clamping assembly 40 can be spaced apart from each other along the height direction of the battery cell, and at the same time clamp and fix the opposite ends of the battery cell in the height direction, thereby balancing the friction between the battery cell and its supporting surface, making the pre-stacking process of the battery cell smoother and reducing the probability of the battery cell falling over during the pre-stacking process.

[0061] In some embodiments, the second clamping assembly 40 is movably disposed on the mounting base 10 along a height direction of the battery cell.

[0062] Specifically, when the tray 20 moves from the pre-stacking position 11 to the pressurizing position 12, the second clamping assembly 40 descends along the height direction of the battery cell until the second clamping assembly 40 can smoothly clamp the upper side of the battery cell along the width direction of the battery cell, so as to facilitate pressurizing the battery cell by pushing the assembly 50.

[0063] When the tray 20 has not moved to the pressurizing position 12, the second clamping assembly 40 does not need to clamp the battery cells. At this time, the second clamping assembly 40 rises along the height direction of the battery cells until it does not affect the battery cells on the tray 20 and follows the tray 20 to move between the pre-stacking position 11 and the pressurizing position 12.

[0064] By making the second clamping assembly 40 movable in the height direction of the battery cell, the second clamping assembly 40 can smoothly clamp the battery cell when the battery cell moves to the pressurizing position 12, and does not affect the movement of the battery cell following the tray 20 under other circumstances, thereby enabling the battery cell to smoothly move between the pre-stacking position 11 and the pressurizing position 12.

[0065] As shown in Figures 3 and 4, in some embodiments, the first clamping assembly 30 and the second clamping assembly 40 both include a first clamping member 31 and a second clamping member 32 respectively arranged on both sides of the tray 20 along the width direction of the battery cell, and at least one of the first clamping member 31 and the second clamping member 32 is configured to be movably arranged along the width direction of the battery cell.

[0066] Specifically, the first clamping member 31 and the second clamping member 32 of the first clamping assembly 30 can be respectively positioned on either side of the tray 20 via telescopic cylinders, allowing the first clamping member 31 and the second clamping member 32 to move closer to or further away from each other along the width direction of the battery cell. When a battery cell is placed on the tray 20, the first clamping member 31 and the second clamping member 32 move closer to each other and clamp the battery cell. When the battery cell needs to be removed from the tray 20, the first clamping member 31 and the second clamping member 32 move further away from each other.

[0067] The first and second clamping members 31, 32 of the second clamping assembly 40 can also be positioned on the mounting base 10 via telescopic cylinders. When the tray 20 moves to the pressurizing position 12, the first and second clamping members 31, 32 of the second clamping assembly 40 are positioned on either side of the tray 20 along the width of the battery cell. By controlling the telescopic cylinders, the first and second clamping members 31, 32 are moved toward each other along the width of the battery cell, thereby clamping the battery cell. After pressurization is complete, the first and second clamping members 31, 32 move away from each other along the width of the battery cell, releasing the battery cell.

[0068] By providing the first clamping member 31 and the second clamping member 32 , the battery cell can be smoothly clamped, so that the battery cell can be stably arranged on the tray 20 and the battery cell can maintain balance during the pressurization process.

[0069] In some embodiments, the second clamping assembly 40 further includes a main body 41 and a first driving member 42. The first driving member 42 is connected between the main body 41 and the mounting base 10 and is used to drive the main body 41 to move along the height direction of the battery cell. The first clamping member 31 and the second clamping member 32 of the second clamping assembly 40 are disposed on the main body 41.

[0070] Specifically, the main body 41 can provide a mounting base for the first driving member 42, the first clamping member 31, and the second clamping member 32. The first driving member 42 can be, but is not limited to, a downward pressure cylinder for driving the main body 41 and driving the first clamping member 31 and the second clamping member 32 on the main body 41 to move along the height direction of the battery cell.

[0071] By providing the main body 41 and the first driving member 42 , the first clamping member 31 and the second clamping member 32 can be driven to move along the height direction of the battery cell, thereby clamping and fixing the battery cell when pressurizing, and avoiding the battery cell when pressurizing is not required.

[0072] In some embodiments, the second clamping assembly 40 further includes a limiting assembly 43 disposed on the main body 41 and located between the first clamping member 31 and the second clamping member 32 . The limiting assembly 43 is used to press each battery cell on the tray 20 along the height direction of the battery cell.

[0073] When the first clamping member 31 and the second clamping member 32 clamp the upper side of the battery cell along the width direction of the battery cell, the limiting assembly 43 is located between the first clamping member 31 and the second clamping member 32 and can press the battery cell downward to stably support the battery cell on the support surface of the tray 20. As a result, the battery cell can be more stable during the pre-stacking process.

[0074] As shown in Figure 5, in some embodiments, the limiting assembly 43 includes a telescopic member 431 and a pressing member 432. The telescopic member 431 is telescopically connected between the main body 41 and the pressing member 432 along the height direction of the battery cell. The pressing member 432 is used to press each battery cell on the tray 20 along the height direction of the battery cell.

[0075] Specifically, the telescopic member 431 may be, but is not limited to, a spring, which is elastically connected between the main body 41 and the pressing member 432 , so that the pressing member 432 can elastically press against the battery cell.

[0076] Furthermore, the number of the telescopic member 431 and the number of the pressing member 432 can be multiple, and the telescopic member 431 and the pressing member 432 are arranged in a one-to-one correspondence.

[0077] It should be noted that each battery cell has a protruding terminal, and due to mechanical errors, there may be a certain degree of error in the height of the terminal of different battery cells. Therefore, each pressing member 432 and telescopic member 431 can press against the terminal of a corresponding battery cell. Moreover, each pressing member 432 can adaptively press against the terminal of the corresponding battery cell under the expansion and contraction of the telescopic member 431, making the pressing effect of the pressing member 432 on each battery cell more stable.

[0078] By providing the telescopic member 431 and the pressing member 432 , the battery cell can be pressed against the tray 20 more stably, so that the battery cell can maintain balance during the process of pushing the battery cell.

[0079] In some embodiments, the pressing member 432 includes a connecting portion 4321 and a rolling portion 4322. The connecting portion 4321 is connected to the telescopic member 431. The rolling portion 4322 is rollably arranged on the connecting portion 4321 along the arrangement direction of the battery cells, and is used to roll and press against each battery cell on the tray 20 along the height direction of the battery cells.

[0080] When there are multiple pressing members 432, each pressing member 432 includes a connecting portion 4321 and a rolling portion 4322. Specifically, the rolling portion 4322 can be, but is not limited to, a roller that rolls on the connecting portion 4321. When the pressing members 432 press against the battery cells, the pushing assembly 50 applies pressure to the battery cells along the arrangement direction of the battery cells, causing the battery cells to move closer together and fit in the arrangement direction.

[0081] At the same time, when the battery cells are displaced along the arrangement direction under the action of thrust, the rolling portion 4322 can roll and press against the battery cells, making the pressing against the battery cells more stable without affecting the movement of the battery cells in the arrangement direction.

[0082] By providing the rolling portion 4322 , the pressing member 432 can achieve rolling pressing against the battery cells, and can continuously apply pressing force when the battery cells move closer to each other along the arrangement direction, making the pressing process more stable.

[0083] As shown in Figure 6, in some embodiments, the pushing assembly 50 includes a supporting member 51 and a pushing member 52, the supporting member 51 is arranged on the tray 20, and the pushing member 52 is movably arranged on the mounting seat 10 along the arrangement direction of the battery cells, and the supporting member 51 and the pushing member 52 are respectively located on both sides of the tray 20 along the arrangement direction of the battery cells, and the pushing member 52 is configured to push each battery cell on the tray 20 to abut against the supporting member 51 along the arrangement direction of the battery cells.

[0084] Specifically, the abutment member 51 is a baffle provided on the tray 20. When the battery cells move with the tray 20 to the pressurizing position 12, the pusher 52 and the abutment member 51 are located on either side of the battery cells along the direction in which the battery cells are arranged. The pusher 52 moves along the direction in which the battery cells are arranged and applies a thrust to the battery cells in this direction, ensuring a tight fit between the multiple battery cells.

[0085] Furthermore, the pusher 52 may be, but is not limited to, a pressurized cylinder. When the battery cells are arranged on the tray 20 along the thickness direction, the pusher 52 extends and applies a thrust on the large surface of the battery cells, thereby enabling the multiple battery cells to fit tightly together.

[0086] Through the cooperation between the abutting member 51 and the pushing member 52 , the pre-stacking of multiple battery cells can be smoothly achieved, so that the battery cells are closely fitted along their arrangement direction, so as to facilitate subsequent assembly.

[0087] Please refer to Figures 1 and 2 again. In some embodiments, the mounting base 10 includes a base 13 and a support member 14 rotatably disposed on the base 13. The support member 14 has a pressurizing position 12 and at least two pre-stacking positions 11 spaced apart along its circumference. Each pre-stacking position 11 is correspondingly provided with a tray 20 and a first clamping assembly 30. The second clamping assembly 40 and the pushing assembly 50 are both disposed at the pressurizing position 12, wherein the second clamping assembly 40 is configured to clamp each battery cell on the tray 20 along the width direction of the battery cell when one of the trays 20 rotates to the pressurizing position 12; and the pushing assembly 50 is configured to push each battery cell on the tray 20 when one of the trays 20 rotates to the pressurizing position 12.

[0088] Specifically, the support member 14 can be configured as a turntable with three pre-stacking positions 11 and one pressurizing position 12 spaced apart along its circumference. Each pre-stacking position 11 and pressurizing position 12 is provided with a tray 20. Multiple battery cells are arranged sequentially along the thickness direction on the tray 20, and a first clamping assembly 30 on the tray 20 clamps and secures the lower sides of the battery cells.

[0089] When the tray 20 rotates to the pressing position 12 along with the turntable, the second clamping assembly 40 moves downward and clamps the upper side of the battery cell. At the same time, the pressing member 432 presses down on the terminal of each battery cell, making the battery cell more stably placed on the tray 20.

[0090] Furthermore, the pushing assembly 50 performs a pushing operation on the battery cells at the pressurizing position 12 , ie, applies a pushing force to the large surface of the battery cells, so that the multiple battery cells can fit together along their arrangement.

[0091] By providing the support members 14 , the battery cells can be stacked synchronously on a plurality of pre-stacking positions 11 and rotated to the pressurizing positions 12 in sequence for pressurization, thereby improving the efficiency of the battery cell pre-stacking process.

[0092] Based on the same concept as the above-mentioned pre-stacking device 100 , the present application also provides a battery processing device, including the above-mentioned pre-stacking device 100 .

[0093] According to one or more embodiments, a plurality of battery cells are first sequentially moved to the tray 20 of the first pre-stacking position 11 by an external robot. After the tray 20 is fully loaded, the first clamping assembly 30 clamps the underside of each battery cell on the tray 20 to stably position the battery cell on the tray 20. The support member 14 is rotated, and the battery cell is moved to the tray 20 of the next pre-stacking position 11.

[0094] As the support member 14 rotates, when one of the trays 20 rotates to the pressing position 12, the second clamping assembly 40 is controlled to descend, clamping and securing the upper side of the battery cell. At the same time, the pressing member 432, under the action of the telescopic member 431, adaptively presses against the corresponding battery cell terminal.

[0095] After the pressure stabilizes, the pusher 52 is controlled to move toward the battery cell, exerting a thrust on the larger surface of the battery cell. This thrust causes the battery cells to move closer together along the arrangement direction and rest against the abutment member 51 until they are tightly fitted together. At this point, the pre-stacking of the battery cells on this tray 20 is complete. The support member 14 continues to rotate to facilitate the pushing operation on the battery cells on the next tray 20.
