[0047] With the development of new energy technology, batteries are used more and more widely, for example, in mobile phones, laptops, electric vehicles, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and power tools.

[0048] During battery manufacturing, transfer devices are often used to move components. The reliability and structural complexity of these devices directly impact their maintenance and operating costs, as well as battery quality and production efficiency, significantly impacting the economic benefits of the battery. Therefore, effectively balancing the reliability and structural complexity of transfer devices remains an ongoing research area in battery technology.

[0049] During the electrode assembly manufacturing process, the transfer device transfers the electrode assembly by clamping it at both ends along its length. During this transfer process, the electrode assembly is in a loose state, and the middle region of the electrode assembly is unsupported. Therefore, the middle region of the electrode assembly on the transfer device is prone to collapse, making the electrode assembly prone to falling during transfer.

[0050] However, transfer devices in related technologies often use a translation mechanism to drive the claw's movement, requiring a large space for translation. This results in a large transfer device and occupies a large amount of space. Furthermore, the structure is relatively complex, making maintenance difficult and costly, thus impacting the overall economic benefits of the battery.

[0051] Based on the above considerations, the present application designs a transferring device, which is used to transfer the electrode assembly. The transferring device includes a frame, a grasping mechanism and a supporting mechanism. The grasping mechanism can be movably connected to the frame. The grasping mechanism includes a first grasping member and a second grasping member. The first grasping member and the second grasping member are arranged opposite to each other along a first direction. The first grasping member and the second grasping member are configured to be able to grasp the electrode assembly by approaching each other along the first direction and move away from each other to release the electrode assembly.

[0052] The supporting mechanism includes a first supporting member connected to one side of the frame along the second direction and rotatable relative to the frame. Within a plane perpendicular to the second direction, an orthographic projection of the first supporting member is located between an orthographic projection of the first gripping member and an orthographic projection of the second gripping member, and the first direction and the second direction intersect. The first supporting member is configured to support or release the electrode assembly by rotating itself.

[0053] The above technical solution introduces a first support member that can lift the central region of the electrode assembly during transfer, thereby improving the stability of the electrode assembly during transfer. Furthermore, the first support member's rotating design effectively reduces the structural complexity and volume of the transfer device.

[0054] Figure 1 This is a schematic diagram of the three-dimensional structure of the transfer device provided in some embodiments of the present application when the first supporting member is in a non-lifting state. Figure 2 This is a schematic diagram of the three-dimensional structure of the transfer device provided in some embodiments of the present application when the first supporting member is in a lifting state. Figure 3 This is a partially enlarged structural schematic diagram of the first supporting member of the transfer device provided in some embodiments of the present application.

[0055] refer to Figures 1 to 3 , an embodiment of the present application provides a transferring device, which is used to transfer the electrode assembly. The transferring device includes a frame 10, a grasping mechanism 20 and a supporting mechanism 30. The grasping mechanism 20 is movably connected to the frame 10. The grasping mechanism 20 includes a first grasping member 21 and a second grasping member 22. The first grasping member 21 and the second grasping member 22 are arranged opposite to each other along a first direction X. The first grasping member 21 and the second grasping member 22 are configured to be able to grasp the electrode assembly by approaching each other along the first direction X and moving away from each other to release the electrode assembly.

[0056] The supporting mechanism 30 includes a first supporting member 31, which is connected to one side of the frame 10 along the second direction Y and is rotatable relative to the frame 10. Within a plane perpendicular to the second direction Y, the orthographic projection of the first supporting member 31 is located between the orthographic projections of the first gripping member 21 and the orthographic projections of the second gripping member 22, and the first direction X and the second direction Y intersect. The first supporting member 31 is configured to rotate to support or release the electrode assembly.

[0057] The gripping mechanism 20 can be detachably connected to the frame 10. The gripping mechanism 20 can be directly connected to the frame 10 or can be restrained on the frame 10 by other components. As an example, the gripping mechanism 20 and the frame 10 can be connected by, but is not limited to, welding, bolting, clamping, riveting, or bonding.

[0058] The driving mode for the first grabbing member 21 and the second grabbing member 22 to move along the first direction X may be, but is not limited to, various modes such as an electric push rod, an air cylinder, or a servo motor driving a screw.

[0059] The first supporting member 31 can be detachably connected to the frame 10. The first supporting member 31 can be directly connected to the frame 10 or can be restrained on the frame 10 by other components. As an example, the connection method between the first supporting member 31 and the frame 10 can be, but is not limited to, welding, bolting, clamping, riveting, or bonding.

[0060] In actual applications, when the transfer device of the embodiment of the present application is used to transfer the electrode assembly, the first grasping member 21 and the second grasping member 22 approach each other along the first direction X and respectively grasp the two ends of the electrode assembly along the first direction X. Then, the first supporting member 31 rotates to lift the electrode assembly. Since the first supporting member 31 is located between the first grasping member 21 and the second grasping member 22, when the first supporting member 31 lifts the electrode assembly, it lifts the position between the two ends of the electrode assembly along the first direction X. Based on this, when the transfer device is carrying the electrode assembly, the middle area of ​​the electrode assembly is supported by the first supporting member 31 and is not easy to collapse, so as to improve the stability of the electrode assembly during the transfer process.

[0061] Moreover, compared with the traditional translation design, the first supporting member 31 in the embodiment of the present application adopts a rotation design, which has significant advantages in terms of structural complexity and volume control. The traditional translation design usually needs to be equipped with a multi-stage structure such as a guide rail, a screw rod or a slider, and supplemented by a motor or cylinder linear drive system. Not only does it have a large number of structural components and complex kinematic pairs, but it also requires a larger installation space and higher assembly precision. The rotation design of the first supporting member 31 in the embodiment of the present application only needs to set up a simple rotation drive source, and can lift or release the electrode assembly by rotating itself, which can effectively reduce the structural complexity of the transfer device and greatly reduce the installation space requirements and overall volume.

[0062] Thus, the above technical solution introduces the first support member 31, which can support the central region of the electrode assembly during transfer, thereby improving the stability of the electrode assembly during transfer. Furthermore, the first support member 31 adopts a rotating design, which can effectively reduce the structural complexity and volume of the transfer device.

[0063] Exemplarily, the first supporting member 31 has a lifting state and a non-lifting state. After the first grasping member 21 and the second grasping member 22 approach each other along the first direction X and respectively grasp the ends of the electrode assembly along the first direction X, the first supporting member 31 rotates from the non-lifting state to the lifting state to lift the electrode assembly. When the transfer device transports the electrode assembly to the target position, the first supporting member 31 rotates again, switching from the lifting state to the non-lifting state to release the support of the electrode assembly. Then, the first grasping member 21 and the second grasping member 22 move away from each other along the first direction X to release the electrode assembly.

[0064] In some embodiments, the rotation axis of the first supporting member 31 is parallel to the third direction Z, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0065] In some embodiments, the supporting mechanism 30 further includes a rotation driving member 32 . The rotation driving member 32 is connected between the first supporting member 31 and the frame 10 . The rotation driving member 32 is used to drive the first supporting member 31 to rotate.

[0066] The rotary drive member 32 can be detachably connected to the frame 10. The rotary drive member 32 can be directly connected to the frame 10 or can be restrained on the frame 10 by other components. As an example, the rotary drive member 32 and the frame 10 can be connected by, but is not limited to, welding, bolting, clamping, riveting, or bonding.

[0067] The first supporting member 31 can be detachably connected to the rotating driving member 32. The first supporting member 31 can be directly connected to the rotating driving member 32, or it can be restrained on the rotating driving member 32 by other components. As an example, the connection method between the first supporting member 31 and the rotating driving member 32 can be, but is not limited to, welding, bolting, clamping, riveting, or bonding.

[0068] Optionally, the rotary drive member 32 may be, but is not limited to, a stepper motor or a servo motor.

[0069] The above technical solution introduces the rotary driving member 32, which can automatically drive the first supporting member 31 to rotate according to demand, thereby improving the overall rhythm matching capability and operating efficiency of the transfer device.

[0070] In some embodiments, the first supporting member 31 includes a first part 311 and a second part 312, the first part 311 is connected to the rotating driving member 32, the second part 312 is connected to an end of the first part 311 away from the rotating driving member 32, and is bent relative to the first part 311 in a direction close to the rotating driving member 32.

[0071] Illustratively, the first portion 311 and the second portion 312 may form an L-shaped structure.

[0072] The second portion 312 can be detachably connected to the first portion 311. The second portion 312 can be directly connected to the first portion 311 or can be restrained on the first portion 311 by other components. As an example, the connection method between the second portion 312 and the first portion 311 can be, but is not limited to, welding, bolting, clamping, riveting, or bonding.

[0073] Optionally, both the first portion 311 and the second portion 312 may be, but are not limited to, plate-shaped structures or columnar structures.

[0074] The first supporting member 31 of the above technical solution has an L-shaped geometric form, which can improve the structural stability of the first supporting member 31 .

[0075] In some embodiments, the first portion 311 and the second portion 312 are integrally formed. This simplifies the manufacturing process by eliminating the need for an additional joining process. Furthermore, the integral structure of the first portion 311 and the second portion 312 provides greater structural strength than would be achieved by joining the first portion 311 and the second portion 312 using an additional joining process.

[0076] In some embodiments, the bending angle between the first portion 311 and the second portion 312 may be 90°.

[0077] In some embodiments, the length of the first portion 311 is 2 mm to 30 mm.

[0078] Exemplarily, the length of the first portion 311 may be understood as the dimension of the first portion 311 along the third direction Z.

[0079] As an example, the length of the first portion 311 may be, but is not limited to, 2 mm, 10 mm, 15 mm, 20 mm, 30 mm, etc.

[0080] In some embodiments, the length of the second portion 312 is 10 mm to 250 mm.

[0081] For example, the length of the second portion 312 can be understood as the dimension of the second portion 312 along the first direction X when the first supporting member 31 is in the non-supporting state. The length of the second portion 312 can also be understood as the dimension of the second portion 312 along the second direction Y when the first supporting member 31 is in the supporting state.

[0082] As an example, the length of the second portion 312 may be, but is not limited to, 10 mm, 50 mm, 100 mm, 150 mm, 250 mm, etc.

[0083] In some embodiments, the width of the second portion 312 is 1 mm-30 mm.

[0084] For example, the width of the second portion 312 can be understood as the dimension of the second portion 312 along the second direction Y when the first supporting member 31 is in the non-supporting state. The width of the second portion 312 can also be understood as the dimension of the second portion 312 along the first direction X when the first supporting member 31 is in the supporting state.

[0085] As an example, the width of the second portion 312 may be, but is not limited to, 1 mm, 5 mm, 10 mm, 20 mm, 30 mm, etc.

[0086] In some embodiments, the thickness of the first portion 311 is 1 mm-5 mm.

[0087] For example, the thickness of the first portion 311 can be understood as the dimension of the first portion 311 along the first direction X when the first supporting member 31 is in the non-supporting state. The thickness of the first portion 311 can also be understood as the dimension of the first portion 311 along the second direction Y when the first supporting member 31 is in the supporting state.

[0088] As an example, the thickness of the first portion 311 may be, but is not limited to, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0089] In some embodiments, the thickness of the second portion 312 is 1 mm-5 mm.

[0090] For example, the thickness of the second portion 312 may be understood as the dimension of the second portion 312 along the third direction Z.

[0091] As an example, the thickness of the second portion 312 may be, but is not limited to, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0092] In some embodiments, the second portion 312 is configured to be telescopically arranged along its own extension direction.

[0093] Exemplarily, the extension direction of the second portion 312 may be understood as the length direction of the second portion 312 .

[0094] The second portion 312 can be retracted along its own extension direction by, but is not limited to, thread adjustment, elastic lock, pin positioning or electric push rod driving.

[0095] As an example, the second portion 312 can be designed as a sleeve-type multi-section structure, with an outer tube fixedly connected to the first portion 311, and an inner sliding tube that can freely extend and retract within the outer tube. Furthermore, to maintain stable positioning, positioning holes, spring pins, or screw fastening devices can be provided on the sleeve to achieve multi-position fixation.

[0096] As another example, the second portion 312 may be designed as a rack and slider structure, where the rotation of the gear drives the slider to move linearly, thereby achieving telescopic adjustment.

[0097] The telescopic function of the second portion 312 allows the first support member 31 to flexibly adjust its lifting range to accommodate electrode assemblies of varying sizes and shapes, providing stable and uniform support. Furthermore, the telescopic second portion 312 can be retracted to its minimum length when not in operation, thereby reducing the static envelope of the transfer mechanism and enhancing equipment layout flexibility within confined spaces, facilitating high-density integration and modular design of production lines.

[0098] In some embodiments, the supporting mechanism 30 further includes a first telescopic driving component, which is connected to the second part 312 and is used to drive the second part 312 to perform telescopic movement along its own extension direction.

[0099] Illustratively, the first telescopic driving component may be, but is not limited to, an electric cylinder or a motor.

[0100] In some embodiments, the first portion 311 is configured to be telescopically disposed along a third direction Z, and the first direction X, the second direction Y, and the third direction Z intersect with each other.

[0101] Exemplarily, the third direction Z may be understood as the length direction of the first portion 311 , that is, the extension direction of the first portion 311 .

[0102] The telescopic arrangement of the first portion 311 along the third direction Z may be achieved by, but is not limited to, thread adjustment, elastic lock, pin positioning, or electric push rod driving.

[0103] As an example, the first portion 311 can be designed as a sleeve-type multi-section structure, with the outer tube fixedly connected to the second portion 312, and the inner sliding tube freely extending and retracting within the outer tube. Furthermore, to maintain stable positioning, positioning holes, spring pins, or screw fastening devices can be provided on the sleeve tube to achieve multi-position fixation.

[0104] As another example, the first portion 311 may also be designed as a rack and slider structure, where the gear rotation drives the slider to move linearly, thereby achieving telescopic adjustment.

[0105] The telescopic function of the first portion 311 can further enhance the working range and supporting coverage capability of the first supporting component 31 .

[0106] In some embodiments, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0107] In some embodiments, the second portion 312 includes a first surface 3121, a second surface 3122 and a first arc surface 3123. The first surface 3121 and the second surface 3122 are arranged opposite to each other along the third direction Z. The first arc surface 3123 is connected between the first surface 3121 and the second surface 3122. The first direction X, the second direction Y and the third direction Z intersect with each other.

[0108] By introducing the first arc surface 3123 , a smooth transition can be formed at the end of the second portion 312 away from the first portion 311 , thereby reducing scratches on the electrode assembly by the angular structure and thereby reducing the risk of damage to the electrode assembly during transfer.

[0109] In some embodiments, the curvature radius of the first arc surface 3123 is 0.5 mm-2 mm.

[0110] As an example, the curvature radius of the first arc surface 3123 can be, but is not limited to, 0.5 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, etc.

[0111] In some embodiments, the first portion 311 includes a third surface 3111 and a second arcuate surface 3112, both of which are located on a side of the first portion 311 facing away from the second portion 312. The first surface 3121 is located on a side of the second portion 312 facing away from the first portion 311, and the second arcuate surface 3112 is connected between the third surface 3111 and the first surface 3121.

[0112] By introducing the second arc surface 3112 , a smooth transition can be formed between the third surface 3111 and the first surface 3121 , thereby reducing stress concentration and structural fatigue problems that may be caused by the right-angle connection and enhancing the structural reliability of the first supporting member 31 .

[0113] In some embodiments, the curvature radius of the second arc surface 3112 is 0.5 mm-2 mm.

[0114] As an example, the curvature radius of the second arc surface 3112 can be, but is not limited to, 0.5 mm, 1 mm, 1.5 mm, 1.8 mm, 2 mm, etc.

[0115] In some embodiments, the first portion 311 includes a fourth surface, which is located on a side of the first portion 311 facing the second portion 312 , and is connected to the second surface 3122 .

[0116] In some embodiments, the fourth surface is perpendicular to the second surface 3122 .

[0117] In some embodiments, the first portion 311 further includes a third arc surface connected between the fourth surface and the second surface 3122 .

[0118] By introducing the third arc surface, a smooth transition can be formed between the fourth surface and the second surface 3122 , thereby reducing stress concentration and structural fatigue problems that may be caused by the right-angle connection and enhancing the structural reliability of the first supporting member 31 .

[0119] In some embodiments, the supporting mechanism 30 further includes a second supporting member connected to the frame 10 and disposed opposite the first supporting member 31. The second supporting member is rotatable relative to the frame 10. Within a plane perpendicular to the second direction Y, the orthographic projection of the second supporting member is located between the orthographic projection of the first gripping member 21 and the orthographic projection of the second gripping member 22. The second supporting member is configured to rotate to lift or release the electrode assembly.

[0120] The second supporting member can be detachably connected to the frame 10. The second supporting member can be directly connected to the frame 10 or can be restrained on the frame 10 by other components. As an example, the connection method between the second supporting member and the frame 10 can be, but is not limited to, welding, bolting, clamping, riveting, or bonding.

[0121] Exemplarily, the first supporting member 31 and the second supporting member have a lifting state and a non-lifting state. After the first grasping member 21 and the second grasping member 22 approach each other along the first direction X and respectively grasp the two ends of the electrode assembly along the first direction X, the first supporting member 31 and the second supporting member rotate themselves to switch from the non-lifting state to the lifting state, thereby lifting the electrode assembly on both sides of the electrode assembly along the second direction Y. When the transfer device transports the electrode assembly to the target position, the first supporting member 31 and the second supporting member rotate again, switching from the lifting state to the non-lifting state to release the support of the electrode assembly. Then, the first grasping member 21 and the second grasping member 22 move away from each other along the first direction X to release the electrode assembly.

[0122] The first supporting member 31 and the second supporting member may rotate synchronously or asynchronously.

[0123] The above technical solution can further improve the stability of the electrode assembly during the transfer process by further introducing the second supporting member.

[0124] It should be noted that the second supporting member may have the same structure as the first supporting member 31 . For specific structural details of the second supporting member, reference may be made to the relevant contents of the first supporting member 31 described above, which will not be repeated here.

[0125] In some embodiments, the first grabbing member 21 includes a first hook 211 and a second hook 212 , which are spaced apart along the second direction Y. The second grabbing member 22 includes a third hook 221 and a fourth hook 222 , which are spaced apart along the second direction Y.

[0126] Exemplarily, the first hook 211 , the second hook 212 , the third hook 221 and the fourth hook 222 may all be L-shaped structures.

[0127] The number of contact points between the gripping mechanism 20 and the electrode assembly can be increased, so that the force distribution of the electrode assembly during the gripping process is more uniform, the risk of damage to the electrode assembly due to excessive local pressure is reduced, and the transfer reliability of the transfer device can be improved.

[0128] In some embodiments, the first hook 211 and the second hook 212 are configured to be movable along the second direction Y toward or away from each other.

[0129] For example, the first hook 211 and the second hook 212 may be driven in the second direction Y in a manner that is not limited to, for example, an electric push rod, a cylinder, or a servo motor driving a screw.

[0130] The adjustable spacing design between the first hook 211 and the second hook 212 can improve the applicability of the grasping mechanism 20. When faced with electrode assemblies of different specifications or shapes, different grasping requirements can be met by simply adjusting the spacing between the first hook 211 and the second hook 212 without replacing the entire grasping mechanism 20, which can effectively improve production efficiency.

[0131] In some embodiments, the third hook 221 and the fourth hook 222 are configured to be movable along the second direction Y toward or away from each other.

[0132] For example, the third hook 221 and the fourth hook 222 are driven to move along the second direction Y in various ways, including but not limited to, an electric push rod, a cylinder, or a servo motor driving a screw.

[0133] The adjustable spacing design between the third hook 221 and the fourth hook 222 can improve the applicability of the grasping mechanism 20. When faced with electrode assemblies of different specifications or shapes, different grasping requirements can be met by simply adjusting the spacing between the third hook 221 and the fourth hook 222 without replacing the entire grasping mechanism 20, which can effectively improve production efficiency.

[0134] In some embodiments, the transfer device further includes a driving mechanism connected to the frame 10 , and the driving mechanism is used to drive the frame 10 to move.

[0135] The drive mechanism can be detachably connected to the frame 10. The drive mechanism can be directly connected to the frame 10 or can be restricted to the frame 10 by other components. As an example, the connection method between the drive mechanism and the frame 10 can be, but is not limited to, welding, bolting, clamping, riveting, or bonding.

[0136] Optionally, the driving mechanism may be but is not limited to a robotic arm, a guide rail slider mechanism, a tracked robot or a wheeled robot, etc.

[0137] The above technical solution can further improve the flexibility and applicability of the transfer device. At the same time, the introduction of the drive mechanism helps to reduce the dependence on manual operation and improve the automation level and operating efficiency of the entire transfer device.

[0138] In some embodiments, the driving mechanism can be used to drive the frame 10 to move along the first direction X.

[0139] In some embodiments, the driving mechanism can be used to drive the frame 10 to move along the second direction Y.

[0140] In some embodiments, the driving mechanism can be used to drive the frame 10 to move along the third direction Z.

[0141] In some embodiments, the electrode assembly is used to transfer a large-capacity battery cell, and the capacity of the large-capacity battery cell is greater than or equal to 300 Ah and less than or equal to 1500 Ah.

[0142] The battery capacity can be measured by the constant current discharge method. The optional capacities of large-capacity battery cells may include 360Ah, 401Ah, 500Ah, 530Ah, 565Ah, 587Ah, 900Ah, 1100Ah, 1200Ah, 1500Ah, etc.

[0143] For large-capacity battery cells with a capacity of 360Ah to 1500Ah, the electrode assembly is larger in size and mass, and the deadweight load is significantly increased, making it more likely to fall during the transfer process.

[0144] Thus, the above technical solution is specifically designed for large-capacity battery cells with capacities ranging from 360Ah to 1500Ah. By introducing the first support member 31, the first support member 31 can support the central region of the electrode assembly during the transfer of the electrode assembly of large-capacity battery cells, thereby improving the stability of the electrode assembly during transfer. Furthermore, the first support member 31 adopts a rotating design, which can effectively reduce the structural complexity and volume of the transfer device.

[0146] In some embodiments, the battery production equipment in this embodiment may be used to produce large-capacity battery cells.

[0147] The battery production equipment in this embodiment can have all the beneficial effects of the above-mentioned transfer device, which will not be described in detail here.

All technical features and optional technical features of the present application can be combined with each other to form a new technical solution.

The first supporting member 31 is connected to one side of the frame 10 along the second direction Y and is rotatable relative to the frame 10. The rotating driving member 32 is connected between the first supporting member 31 and the frame 10, and is used to drive the first supporting member 31 to rotate.

[0152] In the same plane perpendicular to the second direction Y, the orthographic projection of the first supporting member 31 is located between the orthographic projection of the first gripping member 21 and the orthographic projection of the second gripping member 22, and the first direction X and the second direction Y intersect.
