[0058] For cylindrical batteries, trays are typically used during production to support the batteries or battery modules for transport between different processes. During processing, the cells are usually separated from the trays for further processing. Currently, trays are generally transported via external logistics lines, with the use and flow path of the trays flexibly adjusted according to the needs of different processes. However, this transport method suffers from inaccurate tray positioning, which can negatively impact production efficiency.

[0059] In view of this, the present invention provides a conveying device that separates the battery cell from the tray by means of a first clamping component and a first supporting component of a loading and unloading assembly, and synchronously transfers the battery cell and the tray to a carrying assembly by means of a transfer assembly, so that the battery cell can be processed. After processing, the battery cell is reassembled into the tray and rotated together by means of the transfer assembly and the loading and unloading assembly, so that the battery cell and the tray can be matched one-to-one during processing, thereby improving the accuracy of tray positioning and reducing the risk of battery damage.

[0060] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0061] like Figure 1 , Figure 2 , Figure 4 As shown, this utility model provides a conveying device for conveying a target tooling, the target tooling including a detachably connected battery cell and a cup holder. The conveying device includes:

[0062] The loading and unloading assembly 10 includes a first clamping component 11 for clamping the battery cell and a first supporting component 12 for supporting the cup. The first clamping component 11 and the first supporting component 12 are slidably disposed relative to each other and move away from or closer to each other.

[0063] The transfer assembly 20 has a first transfer portion 21 and a second transfer portion 22, the first transfer portion 21 being used to hold the battery cell, and the second transfer portion 22 being used to hold the tray; and

[0064] The carrier assembly 30 is provided with a slidingly disposed second clamping component 31. The second clamping component 31 is fixedly connected to a second support component 32. The second clamping component 31 is used to clamp the battery cell of the first transfer part 21, and the second support component 32 is used to support the cup of the second transfer part 22. The second clamping component 31 and the second support component 32 cooperate to realize that the battery cell and the cup correspond to each other during the processing.

[0065] In this embodiment, the loading / unloading assembly 10 is used for the initial loading and separation of the battery cell and the tray. The battery cell can be removed from the tray for individual processing, and after processing, it can be reinserted into the tray. It is understood that the first clamping component 11 and the first supporting component 12 of the loading / unloading assembly 10 can slide relative to each other, moving closer or further apart, thereby achieving the separation or reassembly of the battery cell and the tray. Furthermore, the transfer assembly 20 can be used for transition, temporarily storing the battery cell and the tray and transferring them to the next assembly. During the transition, the first transfer part 21 can clamp the battery cell, ensuring its stability during transfer; the second transfer part 22 can clamp the tray, ensuring its stability during transfer. The second clamping component 31 of the carrier component 30 can hold the battery cell transferred by the first transfer part 21 for processing. At the same time, the second supporting component 32 of the carrier component 30 can hold the cup transferred by the second transfer part 22, thereby achieving precise positioning and correspondence between the battery cell and the cup during the processing, improving production efficiency, and reducing the risk of battery damage.

[0066] Specifically, the conveying device includes a loading and unloading assembly 10, a transfer assembly 20, and a carrying assembly 30.

[0067] The loading / unloading assembly 10 is used to separate and assemble the battery cell and the cup. The first clamping component 11 can clamp and fix the battery cell, and the first supporting component 12 can support and fix the cup. It can be understood that the loading / unloading assembly 10 can be composed of a loading mechanism and a unloading mechanism with the same structure. When it is necessary to separate the battery cell and the cup, the driving structure of the loading mechanism drives the first clamping component 11 and the first supporting component 12 of the loading mechanism to move away from each other until the battery cell is completely separated from the cup, thereby realizing the separation of the battery cell and the cup. When the battery cell needs to be put back into the cup after processing, the driving structure of the unloading mechanism drives the first clamping component 11 and the first supporting component 12 of the unloading mechanism to move towards each other until the battery cell abuts against the bottom of the cup, thereby realizing the assembly of the battery cell and the cup.

[0068] The transfer assembly 20 is used for the temporary storage and transfer of battery cells and trays. Through the first transfer section 21 and the second transfer section 22, the battery cells and trays on the first clamping member 11 and the first supporting member 12 can be transferred to the second clamping member 31 and the second supporting member 32, allowing the trays to be fed synchronously with the battery cells, ensuring accurate tray positioning. It is understood that both the first transfer section 21 and the second transfer section 22 have clearance spaces, actively creating space during the transfer of battery cells and trays, thereby reducing the possibility of collisions and interference, and ensuring the continuity and stability of the production process.

[0069] The support component 30 carries the battery cell for processing and provides support for the cup, ensuring stable and precise positioning of the cell and cup during processing. The second clamping component 31 and the second support component 32 are fixedly connected to work together, ensuring the cup and cell maintain a corresponding relationship throughout processing. Simultaneously, the sliding mechanism allows the battery cell to be adjusted according to different processing requirements.

[0070] Furthermore, refer to Figure 2 In one embodiment of this utility model, the loading and unloading assembly 10 further includes:

[0071] The frame 13 has a first slide groove 131 and a second slide groove 132 at opposite ends. The first slide groove 131 and the second slide groove 132 each include a far end groove and a near end groove that are connected end to end.

[0072] The first rotating shaft is rotatably mounted on the frame 13;

[0073] The carrier mechanism 14 has multiple fixtures spaced circumferentially along the first axis of rotation for placing target tools. A first clamping component 11 and a first supporting component 12 are respectively located at both ends of the carrier mechanism 14. One end of the carrier mechanism 14 is located in a first slide groove 131, and the other end is located in a second slide groove 132.

[0074] The first driving member is disposed on the frame 13 and driven to drive the first rotating shaft to rotate, so that the two ends of the carrier mechanism 14 enter the far end slot from the proximal end slot to separate the battery cell and the cup, or enter the proximal end slot from the far end slot to assemble the battery cell and the cup.

[0075] In the technical solution adopted in this embodiment, the loading and unloading assembly 10 may include a frame 13, a first rotating shaft, a carrier mechanism 14, and a first driving component. The frame 13 is the supporting structure of the entire loading and unloading assembly 10, used to install other components, and provides a track for the movement of the carrier mechanism 14. In this embodiment, the first driving component can be a motor, driven and connected to the first rotating shaft. The carrier mechanism 14 can be a fixed plate and two movable blocks slidably connected to the fixed plate. When the two movable blocks are respectively located in the proximal slots of the first slide groove 131 and the second slide groove 132, the battery cell and the cup are in an unprocessed assembled state. The motor drives the first rotating shaft to rotate, causing the two movable blocks to slide from the proximal slots into the distal slots, thereby guiding the first clamping component 11 and the first supporting component 12 to separate the battery cell and the cup. When the two movable blocks are respectively located in the distal slots of the first slide groove 131 and the second slide groove 132, the battery cell and the cup are in a processed separated state. The motor drives the first rotating shaft to rotate in the opposite direction, causing the two movable blocks to enter the proximal slots from the distal slots, thereby guiding the first clamping component 11 and the first supporting component 12 to reassemble the battery cell and the cup. It can be understood that the first rotating shaft completes the separation of the battery cell and the cup and transfers them to the next workstation during rotation, or receives the separated battery cell and the cup and completes the assembly during rotation.

[0076] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of this utility model, the vehicle mechanism 14 includes:

[0077] Fixed base 141 is connected to the first rotating shaft;

[0078] The upper slider 142 is slidably connected to the fixed base 141, and an upper cam 143 is provided at the end of the upper slider 142 away from the fixed base 141. The upper cam 143 is movably disposed within the first slide groove 131; and

[0079] The lower slider 144 is slidably connected to the fixed base 141, and the lower slider 144 is provided with a lower cam 145 at the end away from the fixed base 141. The lower cam 145 is movably disposed in the second slide groove 132.

[0080] The first clamping component 11 is disposed on the upper slider 142, and the first supporting component 12 is disposed on the lower slider 144.

[0081] In this embodiment, the carrier mechanism 14 may further include a fixed base 141, an upper slider 142, and a lower slider 144. In this embodiment, the fixed base 141 is connected to the first rotating shaft, enabling the carrier mechanism 14 to rotate around the first rotating shaft, and providing sliding support for the upper slider 142 and the lower slider 144. The upper cam 143 and the lower cam 145, respectively, slide within the first slide groove 131 and the second slide groove 132, converting the rotational motion of the fixed base 141 into the linear motion of the upper slider 142 and the lower slider 144, thereby causing the first clamping member 11 and the first supporting member 12 to move away from or towards each other.

[0082] Furthermore, refer to Figure 2 , Figure 3 In one embodiment of the present invention, the carrier mechanism 14 further includes a magnetic suction element 146 disposed on the first support component 12 for adsorbing the cup.

[0083] In the technical solution adopted in this embodiment, the magnetic suction component 146 can quickly and stably fix the cup on the first support component 12, reducing the risk of the cup shifting due to external force during the separation process and improving the processing accuracy.

[0084] Furthermore, refer to Figure 4 In one embodiment of this utility model, the transfer component 20 includes:

[0085] Transit turret 23, rotating configuration;

[0086] Multiple support blocks 24 are spaced circumferentially along the transfer turret 23. The bottom of each support block 24 is bent and extends away from the support block 24 to form a second transfer section 22; and

[0087] The top of each support block 24 is provided with a transfer gripper 25, which forms the first transfer part 21.

[0088] In this embodiment, the transfer assembly 20 may include a transfer turret 23, a support block 24, and a transfer gripper 25. The transfer turret 23 supports the support block 24 and the transfer gripper 25, enabling the rotational transfer of the battery cell and the tray. The support block 24 supports the tray and can achieve stable placement and transfer of the tray through the bending structure at the bottom, i.e., the second transfer part 22. A transfer gripper 25 is installed on the top of each support block 24, forming a first transfer part 21, which enables precise clamping and transfer of the battery cell. In this embodiment, when the transfer turret 23 rotates to be tangent to the loading / unloading assembly 10, the support block 24 and the transfer gripper 25 receive the separated tray and battery cell through friction, and when tangent to the carrying assembly 30, transfer the tray and battery cell to the carrying assembly 30.

[0089] Furthermore, refer to Figure 5 In one embodiment of this utility model, the supporting component 30 includes:

[0090] The main turret 33 is equipped with a third chute 331;

[0091] The second rotating shaft is rotatably installed inside the main turret 33;

[0092] The side sealing welding mechanism 34 is provided with multiple parts spaced around the second rotating axis and used to carry the battery cell and cup. The second clamping part 31 and the second supporting part 32 are movably disposed on the side sealing welding mechanism 34. One end of the side sealing welding mechanism 34 is disposed in the third slide groove 331.

[0093] The second driving member is disposed on the main turret 33 and drivenly connected to the second rotating shaft to drive the second rotating shaft to rotate, thereby separating the second clamping member 31 from the battery cell, or connecting the second clamping member 31 to the battery cell.

[0094] In this embodiment, the supporting component 30 may include a main turret 33, a second rotating shaft, a side sealing welding mechanism 34, and a second driving component. The main turret 33 is used to install and support other components and provides a track for the movement of the side sealing welding mechanism 34, ensuring its precise movement between different workstations. The third slide 331 may be arranged around the outer periphery of the main turret 33, and the third slide 331 has a connected near-core groove and a far-core groove. In this embodiment, the second driving component can be the aforementioned motor, which is driven and connected to the second rotating shaft. The motor drives the second rotating shaft to rotate, causing the side sealing welding mechanism 34 to carry the battery cell and the cup to a designated position. The second clamping component 31 can include a first end that clamps the housing and a second end that positions the top cover and the housing. During rotation, one end of the side sealing welding mechanism 34 can slide from the far core groove to the near core groove, thereby causing one end of the side sealing welding mechanism 34 to rise. During the rising process, the first end of the second clamping component 31 clamps the battery housing, and the second end of the second clamping component 31 coincides with the top of the battery cell, ensuring that the top cover and the housing are concentric. During the continued rising process, the second end of the second clamping component 31 opens to facilitate processing. After processing is completed, one end of the side sealing welding mechanism 34 can slide from the near core groove to the far core groove for subsequent transfer.

[0095] Furthermore, refer to Figure 6 , Figure 7 In one embodiment of this utility model, the side sealing welding mechanism 34 includes:

[0096] The base 341 is connected to the second rotating shaft, and the base 341 is provided with a limiting seat 3411;

[0097] The base 342 is slidably connected to the base 341, and one end of the base 342 is provided with a movable cam 343, which is located in the third slide groove 331. The second support member 32 is located on the base 342.

[0098] Mounting base 344, which is provided with mechanical follower gripper 345 and concentric gripper 346. The mechanical follower gripper 345 and concentric gripper 346 form a second clamping component 31. Mounting base 344 is movably connected to base 342 so that the mechanical follower gripper 345 and concentric gripper 346 open or close as the mounting base 344 rises or falls.

[0099] A locking screw 3441 is provided on the mounting base 344, and a compression spring 3442 is provided on the locking screw 3441. The compression spring 3442 cooperates with the limiting seat 3411 to realize the lifting and lowering of the mounting base 3444; and

[0100] A drive motor 348 is located at one end of the base 341 near the second clamping member 31. The drive motor 348 is movably connected to the battery cell to drive the battery cell to rotate.

[0101] In this embodiment, the side-sealing welding mechanism 34 may include a base 341, a base 342, a mounting base 344, and a drive motor 348. The base 341 enables the side-sealing welding mechanism 34 to rotate following the second rotating shaft. The base 342 supports the second support member 32 and slides along the third slide groove 331 via a movable cam 343. The mounting base 344 supports the second clamping member 31 and enables lifting or lowering movements. In this embodiment, a locking screw 3441 is provided on one side of the mounting base 344, and a compression spring 3442 is provided inside the locking screw 3441. A limiting seat 3411 is provided on the base 341. The locking screw 3441 is limited by the limiting seat 3411, and the compression spring 3442 is compressed, causing the mounting base 344 to rise, so that the mechanical follower gripper 345 opens. When the movable cam 343 rises to a certain height, the locking screw 3441 separates from the limiting seat 3411, the compression spring 3442 springs open, causing the mounting base 344 to fall, and the mechanical follower gripper 345 closes. At the same time, the concentric gripper 346 fixed on the mounting base 344 falls and coincides with the top of the battery cell. The movable cam 343 continues to rise to the height positioning, the concentric gripper 346 opens, and the drive motor 348 rotates to a constant speed, causing the battery cell to rotate, thereby facilitating the pre-welding process of the battery cell. It should be noted that the mechanical follower gripper 345 is a follower component at its contact point with the battery cell housing. When the drive motor 348 drives the battery cell to rotate, the follower component is positioned accordingly. The follower component can be a bearing, which is not limited here. In another embodiment, the mounting base 344 is provided with a mechanical follower gripper 345, which forms a second clamping component 31. The mounting base 344 is movably connected to the base 342 so that the mechanical follower gripper 345 opens or closes as the mounting base 344 rises or falls, thereby performing full soldering processing on the battery cell.

[0102] Furthermore, refer to Figure 6 , Figure 7 In one embodiment of the present invention, the side sealing welding mechanism 34 further includes a height adjustment block 347, which is movably disposed on the mounting base 344 and abuts against the bottom of the battery cell to achieve the same top height for battery cells of different heights.

[0103] In the technical solution adopted in this embodiment, the bottom of the battery cell can be supported by the height adjustment block 347. Moreover, the height adjustment block 347 is movably connected to the mounting base 344, so that the position of the height adjustment block 347 is adjustable, thereby enabling the side sealing welding mechanism 34 to be compatible with battery cells of different heights and ensuring that the top height of the battery cells is the same.

[0104] This utility model also provides a battery production system, which includes an assembly line and the conveying device described above. The specific structure of the conveying device is as described in the above embodiments. Since this battery production system adopts all the technical solutions in the above embodiments, it has at least all the beneficial effects brought about by the technical solutions in the above embodiments, which will not be described in detail here.

[0105] The production line is the core component of a battery production system, used to transport semi-finished products such as battery cells and cup holders. Depending on the specific needs of the battery cell production process, conveyor devices can be integrated into the production line, allowing the battery cells to detach from the cup holders during processing and return to them for rotation after completion. This achieves synchronous feeding of the battery cells and cup holders, ensuring a one-to-one correspondence between cells and cup holders. It eliminates the need for external turrets or external logistics lines for the cup holders, improves the accuracy of cup holder positioning, and significantly reduces costs.

[0106] Furthermore, refer to Figure 1 , Figure 8 In one embodiment of this utility model, two sets of conveying devices are provided. The battery production system also includes a pre-welding laser head 40, a gap detection mechanism 50, and a first main drive assembly 80. The first main drive assembly 80 is used to drive one set of conveying devices. The pre-welding laser head 40 and the gap detection mechanism 50 are fixedly mounted on one side of the bearing assembly 30. The first main drive assembly 80 is connected to the loading and unloading assembly 10, the transfer assembly 20, and the bearing assembly 30 respectively to complete the pre-welding action of the battery cell.

[0107] The battery production system also includes a full-welding laser head 60, a weld seam detection mechanism 70, and a second main drive assembly 90. The second main drive assembly 90 is used to drive another set of conveying devices. The full-welding laser head 60 and the weld seam detection mechanism 70 are fixedly mounted on one side of the bearing assembly 30. The second main drive assembly 90 is connected to the bearing assembly 30, the transfer assembly 20, and the loading and unloading assembly 10 respectively to complete the full-welding action.

[0108] The pre-welding and full-welding processes are carried out simultaneously.

[0109] In this embodiment, the pre-welding laser head 40 is used for preliminary welding between the battery casing and the cover plate, ensuring initial fixation and sealing of the welded area. The main purpose of pre-welding is to provide a stable welding foundation for subsequent full welding. The gap detection mechanism 50 typically uses a CCD industrial camera and light source to detect the gap between the battery casing and the cover plate before pre-welding, effectively avoiding welding defects and improving welding quality. The full welding laser head 60 is used to complete the final welding of the battery casing and the cover plate. Full welding requires the weld to be completely fused without gaps to achieve a seamless connection. The weld detection mechanism 70 is used to detect the weld quality after full welding, mainly detecting the flatness of the weld, the presence of incomplete welds, and the amount of weld deformation. The weld detection mechanism 70 typically includes 3D detection and 2D detection. 2D detection mainly identifies and analyzes welding defects through two-dimensional images. It typically uses a camera to capture planar images of the weld and uses image processing algorithms to detect defects. The advantages of 2D detection are high speed and low cost, and it is suitable for detecting surface defects and shape features of welds. 3D inspection analyzes the shape and size of welds using three-dimensional point cloud data, providing more comprehensive weld information, including geometric parameters such as height, width, and depth. It is suitable for detecting volumetric defects and complex shapes in welds. Combining 2D and 3D methods enables more efficient and accurate weld quality inspection. In this embodiment, when pre-welding and full-welding are required in the battery production system, the conveying device may include a loading / unloading assembly 10 for separating battery cells and cups, a support assembly 30 for pre-welding, a support assembly 30 for full-welding, a loading / unloading assembly 10 for assembling battery cells and cups, and multiple transfer assemblies 20. Understandably, the process involves first separating the battery cell and the tray using the loading / unloading assembly 10. Then, the separated battery cell and tray are transferred to the pre-welding support assembly 30 via the transfer assembly 20 for pre-welding. Next, the pre-welded battery cell and tray are simultaneously transferred to the full-welding support assembly 30 via the transfer assembly 20. Finally, the processed battery cell and tray are transferred to another loading / unloading assembly 10 via the transfer assembly 20 for reassembly, thus completing the battery cell processing. Additionally, a first main drive assembly 80 and a second main drive assembly 90 are configured separately. The first main drive assembly 80 uses a motor-driven gear set linkage to synchronously rotate the loading / unloading assembly 10 for separating the battery cell and tray, the first transfer turret 20, and the pre-welding support assembly 30. The second main drive assembly 90 uses the same motor-driven gear set linkage to synchronously rotate the support assembly 30 for full-welding, the third transfer turret 20, and the loading / unloading assembly 10 for assembling the battery cell and tray. It should be noted that the motors of the first main drive assembly 80 and the second main drive assembly 90 rotate at the same frequency to ensure the synchronization and consistency of the pre-welding action and the full-welding action.
