Description

Technical Field

[0001] This application relates to the field of battery cell delivery technology, and in particular to a battery cell delivery device. Background Technology

[0002] Due to differences in process requirements and spatial layout across different sections, the orientation and arrangement of battery cells between adjacent conveyor lines often need to be adjusted accordingly. For example... Figure 1 As shown, the first conveyor line 110 and the second conveyor line 120 are arranged at intervals along a first direction, and both the first conveyor line 110 and the second conveyor line 120 are used to convey battery cells 130 along the first direction. On the first conveyor line 110, the battery cells 130 are placed along the second direction (the second direction and the first direction are perpendicular to each other in the horizontal plane) in a length direction, and are arranged side by side in two rows in this orientation. However, on the second conveyor line 120, the battery cells 130 are arranged along the first direction in a length direction, and each battery cell 130 is arranged at intervals along the first direction in a single row on this conveyor line. Thus, during the production process, a handling device needs to be arranged between the first conveyor line 110 and the second conveyor line 120 to transport the battery cells 130 on the first conveyor line 110 to the second conveyor line 120.

[0003] Currently, the operation process of the handling equipment is as follows: After the first conveyor line steps and transports the battery cells to the designated unloading station, the handling equipment starts and moves above the unloading station; the handling equipment simultaneously grabs two battery cells located at the unloading station through the clamping mechanism; the handling equipment drives the battery cells to be vertically lifted to detach from the first conveyor line; after being lifted to the set height, the handling equipment drives the clamping mechanism to rotate 90° in the horizontal plane; then, the handling equipment moves horizontally to the receiving station above the second conveyor line; next, the handling equipment lowers the battery cells and releases them onto the surface of the second conveyor line, thus completing one handling operation; finally, the handling equipment rises unloaded and rotates 90° to reset and returns to the unloading station above the first conveyor line to wait for the next work cycle.

[0004] Because existing material handling equipment needs to be reset under no-load conditions during operation, this means that the equipment spends more than half the time on ineffective movement rather than performing grabbing or placing operations. This not only affects production efficiency but also causes additional energy consumption and equipment wear. Utility Model Content

[0005] (a) The problem to be solved by this application is that the existing battery cell handling equipment has low operating efficiency and high operating cost.

[0006] (II) Technical Solution To address the aforementioned technical problems, this application provides a battery cell conveying device, which includes a first driving component, a second driving component, a lifting base, a rotating beam, a transmission assembly, and two clamping assemblies, wherein: The first driving component is connected to the lifting seat and drives the lifting seat to move in the vertical direction; the second driving component is fixedly installed on the lifting seat. The transmission assembly includes a first transmission wheel, a drive wheel, and a second transmission wheel arranged sequentially at intervals along the length of the rotating beam, and a transmission belt fitted onto the first transmission wheel, the drive wheel, and the second transmission wheel. The first transmission wheel and the second transmission wheel are rotatably mounted on the rotating beam, and the drive wheel is fixedly mounted on the lifting seat. The transmission ratio between the drive wheel and the first transmission wheel is 2:1, and the transmission ratio between the drive wheel and the second transmission wheel is 2:1. The second driving component is connected to the rotating beam via a transmission and drives the rotating beam to rotate around the axis of the driving wheel in the horizontal plane; The first clamping assembly is driven to the first drive wheel, and the second clamping assembly is driven to the second drive wheel. Each clamping assembly includes at least two clamping members for clamping the battery cells. The two clamping assemblies are respectively used to clamp at least two battery cells that are parallel along the length direction of the battery cells on the first conveying line, and to place the clamped battery cells side by side on the second conveying line along the conveying direction of the second conveying line. When the first clamping assembly is located at the unloading end of the first conveyor line, the second clamping assembly is located at the loading end of the second conveyor line; when the first clamping assembly is located at the loading end of the second conveyor line, the second clamping assembly is located at the unloading end of the first conveyor line.

[0007] When the battery cell conveying equipment is arranged between the first and second conveyor lines to transfer battery cells from the first conveyor line to the second conveyor line, initially, the clamping members of the first clamping assembly are arranged along the second direction and located above the unloading end of the first conveyor line, while the clamping members of the second clamping assembly are arranged along the first direction and located above the conveying surface of the second conveyor line. After the equipment starts operating, the first driving component drives the lifting seat to descend, bringing the first clamping assembly closer to the unloading end of the first conveyor line. Subsequently, the clamping members of the first clamping assembly actuate and grab the battery cells arranged side by side on the unloading end of the first conveyor line. After the grabbing is completed, the first driving component drives the lifting seat to rise to a safe height. Next, the second driving component drives the rotating beam to rotate 180°. Since the driving wheel is fixed on the lifting seat rather than on the rotating beam, the rotating beam can rotate around the axis of the driving wheel in the horizontal plane. The transmission ratio between the driving wheel and the first transmission wheel is 2:1, and the transmission ratio between the driving wheel and the second transmission wheel is 2:1. Therefore, after the rotating beam has rotated 180°, the first transmission wheel and the second transmission wheel will each rotate 90° through the meshing transmission belt. This combined motion causes the first clamping component to move above the feeding end of the second conveyor line while rotating with the rotating beam, and at the same time, it also rotates 90° with the first transmission wheel. Similarly, the second clamping component moves above the feeding end of the first conveyor line while rotating, and at the same time, it also rotates 90° with the second transmission wheel. Subsequently, the first drive unit drives the lifting platform to descend again. At this time, the first clamping component, which has moved to the upper end of the second conveyor line, places the battery cell it is holding on the upper end of the second conveyor line, with the battery cell arranged along the first direction in its length direction. Simultaneously, the second clamping component, which has moved to the lower end of the first conveyor line, simultaneously grabs a set of battery cells from the upper and lower ends of the first conveyor line. By continuously repeating the above actions, the next identical work cycle can be seamlessly started. The battery cell conveying equipment combines the 180° revolution of the rotating beam with the 90° rotation of the clamping components, and in one compound action, it simultaneously completes the exchange of positions between the two sets of clamping components, the reversal of battery cell direction, and the feeding and picking of materials, fundamentally eliminating the idle waiting time between processes of traditional handling equipment and greatly improving production efficiency.

[0008] Optionally, the inner and outer surfaces of the transmission belt are provided with first meshing teeth; the first transmission wheel, the drive wheel, and the second transmission wheel are each provided with second meshing teeth that match the first meshing teeth; the second meshing teeth of the first transmission wheel mesh with the first meshing teeth on the inner surface of the transmission belt; and the second meshing teeth of the second transmission wheel and the drive wheel mesh with the first meshing teeth on the outer surface of the transmission belt.

[0009] By rotating in opposite directions with the first and second drive wheels, it is ensured that the battery cells carried by the two clamping components are in the correct orientation when they arrive at the target conveyor line, strictly conforming to the layout requirements of the corresponding conveyor line. This ensures that the battery cells placed on the second conveyor line are arranged in a predetermined order, providing a guarantee for the precise operation of subsequent processes. It also avoids process interruptions or product quality problems caused by disordered battery cell order, significantly improving the stability and production efficiency of the entire production line.

[0010] Optionally, the transmission belt includes a belt body, a first connector, and a second connector; The belt is long and has a first end and a second end that are arranged opposite to each other. A first connector is fixedly disposed at the first end of the belt, and a second connector is fixedly disposed at the second end of the belt. The first connector and the second connector are detachably connected.

[0011] The detachable connection between the first and second connecting parts allows for quick replacement of the drive belt without disassembling the core components. When replacement is needed, simply detaching the first and second connecting parts enables belt removal. This process eliminates the need to disassemble the entire equipment structure, significantly reducing maintenance time and downtime losses. Furthermore, the detachable structure allows for flexible adjustment of the drive belt length to meet specific needs. The first and second connecting parts can be secured with bolts, allowing for belt tension adjustment by changing the position of the nut.

[0012] Optionally, a slide rail is fixedly installed on the rotating beam; The first connector is provided with a first slider that cooperates with the slide rail, and the second connector is provided with a second slider that cooperates with the slide rail; both the first slider and the second slider are slidably connected to the slide rail.

[0013] By setting a slide rail and a first slider that is slidably connected to the slide rail on the first connector and a second slider that is slidably connected to the slide rail on the second connector, guide support is provided for both ends of the transmission belt, ensuring the running accuracy of the transmission belt; at the same time, it makes the movement of the transmission belt smoother, reduces component wear, and extends the service life of the transmission components.

[0014] Optionally, the transmission assembly further includes a second guide wheel and a third guide wheel that are rotatably disposed on the side of the rotating beam. The second guide wheel and the third guide wheel are abutted against the transmission belt so that the portion of the transmission belt between the second guide wheel and the third guide wheel extends along the length of the rotating beam. The first connector and the second connector are located on the portion of the transmission belt between the second guide wheel and the third guide wheel.

[0015] The second and third guide wheels are designed to form a constraint by abutting against the transmission belt, ensuring that the transmission belt in the sections containing the first and second connectors extends strictly along the length of the rotating beam. This ensures that the first and second connectors are always under stable stress and avoids the problem of the slider and slide rail getting stuck due to the bending of the transmission belt.

[0016] Optionally, each clamping assembly also includes a mounting plate and a connecting shaft. Each clamping member of each clamping assembly is spaced apart on the lower surface of the corresponding mounting plate, and the connecting shaft of each clamping assembly is fixedly mounted on the upper surface of the corresponding mounting plate. The connecting shafts of the two clamping components are rotatably mounted on the rotating beam via bearings. The connecting shaft of the first clamping component is connected to the first transmission wheel, and the connecting shaft of the second clamping component is connected to the second transmission wheel.

[0017] The connecting shaft is rotatably connected to the rotating beam via bearings. This ensures that the clamping components move synchronously with the rotating beam during its revolution, while also providing flexible rotational support for the clamping components' rotation. This reduces frictional resistance during rotation, making the drive wheel's rotation of the clamping components smoother and preventing jamming. The mounting plate provides a mounting base for multiple clamping components, ensuring their stability. Furthermore, the direct connection between the mounting plate and the drive wheel via the connecting shaft shortens the power transmission path, reduces power loss, and ensures that the rotational motion of the drive wheel is transmitted quickly and accurately to the clamping components. This allows for more timely and accurate commutation of the battery cells, preventing misplacement of the cells due to power transmission delays.

[0018] Optionally, the cell delivery equipment also includes a turntable and multiple support rods; The turntable is fixedly mounted on the output end of the second drive component, and the two ends of each support rod are fixed to the turntable and the rotating beam, respectively. Multiple support rods are evenly distributed on the outside of the drive wheel to evenly support the rotating beam.

[0019] As the core component supporting the transmission and clamping assemblies, the rotating beam must bear the weight of the clamping assemblies and the battery cells during operation, while also withstanding the centrifugal force and torque generated by the combined revolution and rotation. The multiple evenly distributed support rods in this application uniformly transmit the weight and force of the rotating beam to the turntable, and then from the turntable to the second drive component. This effectively disperses localized stress and prevents deformation of the rotating beam due to concentrated stress. Simultaneously, the evenly distributed support rods can counteract the centrifugal force generated during rotation, reducing the vibration amplitude of the rotating beam and making its revolution smoother. This avoids meshing misalignment or transmission ratio deviation caused by vibration, thereby ensuring the precise movement of the clamping assemblies and making the transfer and reversal of the battery cells more reliable.

[0020] Optionally, the transmission assembly also includes two first guide wheels, each located on one of the two support rods. The two first guide wheels are located on opposite sides of the drive wheel and rest against the transmission belt so that at least half of the drive wheel is engaged with the transmission belt.

[0021] Two first guide wheels are symmetrically distributed on both sides of the drive wheel. By abutting against the drive belt, they create a three-point positioning constraint, ensuring the drive belt tightly contacts the outer surface of the drive wheel. This ensures at least half of the drive wheel's teeth are engaged with the drive belt, significantly increasing the meshing area. This not only improves the transmission's load-bearing capacity and effectively transmits drive torque, preventing excessive tooth wear due to insufficient meshing area, but also ensures a stable meshing relationship between the drive belt and the drive wheel, preventing disengagement or slippage. Furthermore, the improved meshing stability allows the clamping assembly to precisely rotate 90° when the rotating beam revolves 180°, ensuring the battery cell's orientation on the second conveyor line strictly conforms to process requirements and preventing directional deviations from affecting subsequent processes. In addition, the first guide wheels are mounted on the support rod, reducing redundant components, lowering assembly difficulty, and facilitating subsequent inspection and maintenance, further enhancing the equipment's practicality and operational reliability.

[0022] Optionally, the cell conveying equipment also includes a support frame; the support frame is provided with a guide rod extending in a vertical direction, and the lifting seat is provided with a sliding sleeve that matches the guide rod, the sliding sleeve being slidably connected to the guide rod; the first driving component is fixedly mounted on the support frame.

[0023] The sliding fit structure between the guide rod and the sliding sleeve provides guidance and constraint for the lifting motion of the lifting seat, ensuring that the lifting seat can move smoothly and strictly in the vertical direction and avoid deviation. At the same time, the sliding connection between the sliding sleeve and the guide rod reduces the frictional resistance of the lifting motion, making the lifting seat more smoothly and responding more quickly when the first drive component drives the lifting seat to rise and fall, and enabling rapid adjustment of the height of the clamping assembly.

[0024] Optionally, the clamping device includes a double-headed cylinder and two grippers. The double-headed cylinder is used to drive the two grippers to move closer together to clamp the battery cell or to move away from each other to release the battery cell.

[0025] The double-headed cylinder can provide symmetrical and uniform clamping force, thereby ensuring that the battery cell is subjected to balanced force when clamped, which can protect the battery cell; at the same time, the double-headed cylinder also has the characteristic of fast response speed.

[0035] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] This application provides a battery cell conveying device that can transfer battery cells 130 from a first conveying line 110 to a second conveying line 120, wherein, as... Figure 1 As shown, the first conveyor line 110 and the second conveyor line 120 are arranged at intervals along the first direction, and both the first conveyor line 110 and the second conveyor line 120 are used to convey the battery cells 130 along the first direction; on the first conveyor line 110, the length direction of the battery cells 130 is parallel to the second direction, and the second direction is perpendicular to the first direction in the horizontal plane, and they are arranged side by side in two rows in the first direction in this posture; on the second conveyor line 120, the length direction of the battery cells 130 is parallel to the first direction, and each battery cell 130 is arranged at intervals in a single row along the first direction on the second conveyor line 120.

[0037] like Figures 2 to 6As shown, the battery cell conveying equipment includes a first driving component 210, a second driving component 220, a lifting seat 230, a rotating beam 240, a transmission assembly 250, and two clamping assemblies 260; wherein: the first driving component 210 is connected to the lifting seat 230 in a transmission manner, and the first driving component 210 is used to drive the lifting seat 230 to move in the vertical direction; the second driving component 220 can be fixedly installed on the lifting seat 230 by means of screw connection or snap connection. The rotating beam 240 has a long strip structure. The transmission assembly 250 includes a first transmission wheel 251, a drive wheel 252, and a second transmission wheel 253 arranged sequentially at intervals along the length of the rotating beam 240, and a transmission belt 254 fitted onto the first transmission wheel 251, the drive wheel 252, and the second transmission wheel 253. The first transmission wheel 251 and the second transmission wheel 253 are rotatably mounted on the rotating beam 240. The drive wheel 252 is fixedly mounted on the lifting seat 230. The transmission ratio between the drive wheel 252 and the first transmission wheel 251 is 2:1, and the transmission ratio between the drive wheel 252 and the second transmission wheel 253 is 2:1. The second driving component 220... A first clamping assembly 260 is connected to a rotating beam 240 and drives the rotating beam 240 to rotate around the axis of the drive wheel 252 in a horizontal plane. A second clamping assembly 260 is connected to a first drive wheel 251 and a second drive wheel 253. Each clamping assembly 260 includes at least two clamping members 262 for clamping the battery cells 130. The two clamping assemblies 260 are respectively used to clamp at least two battery cells 130 arranged side-by-side along the length of the battery cells 130 on the first conveyor line 110, and to place the clamped battery cells 130 side-by-side on the second conveyor line 120 along the conveying direction of the second conveyor line 120. When the first clamping assembly 260 is located at the unloading end of the first conveyor line 110, the second clamping assembly 260 is located at the loading end of the second conveyor line 120; when the first clamping assembly 260 is located at the loading end of the second conveyor line 120, the second clamping assembly 260 is located at the unloading end of the first conveyor line 110.

[0038] When the cell conveying equipment is arranged between the first conveyor line 110 and the second conveyor line 120 to transfer the cells 130 on the first conveyor line 110 to the second conveyor line 120, the first conveyor line 110 and the second conveyor line 120 are arranged at intervals along a first direction, and both the first conveyor line 110 and the second conveyor line 120 are used to convey the cells 130 along the first direction; on the first conveyor line 110, the cells 130 are placed along a second direction (the second direction and the first direction are perpendicular to each other in the horizontal plane) in the length direction, and are arranged side by side in two rows in this posture in the second direction; on the second conveyor line 120, the cells 130 are arranged along the first direction in the length direction, and each cell 130 on the second conveyor line... The first conveyor line 110 is arranged in a single row along the first direction; the clamping assembly 260 is equipped with two clamping members 262; in the initial state, the two clamping members 262 of the first clamping assembly 260 are arranged along the second direction and located above the unloading end of the first conveyor line 110, and the two clamping members 262 of the second clamping assembly 260 are arranged along the first direction and located above the conveying surface of the second conveyor line 120; after the equipment starts running, the first driving member 210 drives the lifting seat 230 to descend, so that the first clamping assembly 260 approaches the unloading end of the first conveyor line 110, and then the two clamping members 262 of the first clamping assembly 260 move and grab the two battery cells 130 arranged side by side on the unloading end of the first conveyor line 110. After the grabbing is completed, the first driving member 210 drives the lifting seat 230 to rise to a safe height. Next, the second driving component 220 drives the rotating beam 240 to rotate 180°. Since the driving wheel 252 is fixed on the lifting seat 230 rather than the rotating beam 240, the rotating beam 240 can rotate around the axis of the driving wheel 252 in the horizontal plane. The transmission ratio between the driving wheel 252 and the first transmission wheel 251 is 2:1, and the transmission ratio between the driving wheel 252 and the second transmission wheel 253 is 2:1. After the rotating beam 240 revolves 180°, through the meshing transmission of the transmission belt 254, the first transmission wheel 251 and the second transmission wheel 253 will each rotate 90°. This combined motion causes the first clamping component 260 to rotate 90° along with the first transmission wheel 251 while moving above the loading end of the second conveyor line 120 as the rotating beam 240 revolves. Similarly, the second clamping component 260 rotates 90° along with the second transmission wheel 253 while moving above the unloading end of the first conveyor line 110. Subsequently, the first drive component 210 drives the lifting seat 230 to descend again. At this time, the first clamping component 260, which has moved to the upper end of the second conveyor line 120, places the two battery cells 130 it is holding on the upper end of the second conveyor line 120. These two battery cells 130 are arranged along the first direction in the length direction. At the same time, the second clamping component 260, which has moved to the upper end of the first conveyor line 110, simultaneously grabs the two battery cells 130 in the upper and lower groups at the lower end of the first conveyor line 110. By continuously repeating the above actions, the next identical work cycle can be seamlessly started.The battery cell conveying equipment combines the 180° revolution of the rotating beam 240 with the 90° rotation of the clamping assembly 260. In one compound action, it simultaneously completes the exchange of workstations of the two sets of clamping assemblies 260, the reversal of the battery cell 130, and the feeding and picking of materials. This fundamentally eliminates the idle waiting time between processes of traditional handling equipment and greatly improves production efficiency.

[0039] Specifically, when the rotating beam 240 rotates around the axis of the drive wheel 252 in the horizontal plane, the transmission belt 254 on the rotating beam 240 will also move relative to the drive wheel 252. Since the drive wheel 252 is fixed, the meshing teeth on the transmission belt 254 that mesh with the drive wheel 252 will change continuously. However, the relative position of the transmission belt 254 and the drive wheel 252 remains unchanged. The transmission belt 254 must creep along its own length direction so that new meshing teeth can move to the drive wheel 252 and mesh with it. Thus, the rotation of the rotating beam 240 realizes the creeping of the transmission belt 254 along its own length direction, which in turn drives the first transmission wheel 251 and the second transmission wheel 253 to rotate, and finally makes the two clamping components 260 rotate.

[0040] In optional implementations of this application, such as Figure 5 and Figure 6 As shown, the inner and outer surfaces of the transmission belt 254 are provided with first meshing teeth; the first transmission wheel 251, the drive wheel 252, and the second transmission wheel 253 are all provided with second meshing teeth that match the first meshing teeth; the second meshing teeth of the first transmission wheel 251 mesh with the first meshing teeth on the inner surface of the transmission belt 254, and the second meshing teeth of the second transmission wheel 253 and the drive wheel 252 mesh with the first meshing teeth on the outer surface of the transmission belt 254; thus, when the rotating beam 240 rotates 180° clockwise, the first transmission wheel 251 can rotate 90° clockwise, and the second transmission wheel 253 can rotate 90° counterclockwise.

[0041] By rotating in opposite directions with the first drive wheel 251 and the second drive wheel 253, it is ensured that the battery cells 130 carried by the two clamping assemblies 260 are in the correct orientation when they arrive at the target conveyor line, strictly conforming to the layout requirements of the corresponding conveyor line. This ensures that the battery cells 130 placed on the second conveyor line 120 are arranged in a predetermined order, providing a guarantee for the precise operation of subsequent processes. It also avoids process interruptions or product quality problems caused by disordered battery cell sequence, significantly improving the stability and production efficiency of the entire production line.

[0042] For example, such as Figures 7 to 9As shown, the first clamping assembly 260 has two clamping members 262, namely clamping member A1 and clamping member A2; the second clamping assembly 260 has two clamping members 262, namely clamping member B1 and clamping member B2; the six battery cells 130 on the first conveyor line 110 are battery cell C1, battery cell C2, battery cell C3, battery cell C4, battery cell C5 and battery cell C6. In the initial state, as... Figure 7 As shown, the clamping member A1 of the first clamping assembly 260 is located above the battery cell C1, and the clamping member A2 of the first clamping assembly 260 is located above the battery cell C2; the clamping members B1 and B2 of the second clamping assembly 260 are located above the second conveyor line 120. After the equipment starts running, the first drive member 210 drives the lifting seat 230 to descend, so that the first clamping assembly 260 approaches the unloading end of the first conveyor line 110. The clamping member A1 of the first clamping assembly 260 grips the battery cell C1, and the clamping member A2 of the first clamping assembly 260 grips the battery cell C2. After gripping is completed, the first drive member 210 drives the lifting seat 230 to rise to a safe height.

[0043] Immediately afterwards, the second driving component 220 drives the rotating beam 240 to rotate 180° clockwise. During this process, the first clamping assembly 260 switches with the rotating beam 240 to the top of the feeding end of the second conveyor line 120, and the second clamping assembly 260 switches with the rotating beam 240 to the top of the unloading end of the first conveyor line 110. Under the action of the transmission assembly 250, the first clamping assembly 260 rotates 90° clockwise, and the second clamping assembly 260 rotates 90° counterclockwise. At this time, the positions of the clamping parts A1 and A2 of the first clamping assembly 260, the clamping parts B1 and B2 of the second clamping assembly 260, and the battery cells C1 and C2 are as follows: Figure 8 As shown. Subsequently, the first drive unit 210 drives the lifting platform 230 to descend, bringing the first clamping assembly 260 close to the loading end of the second conveyor line 120. The clamping members A1 and A2 of the first clamping assembly 260 place battery cells C1 and C2 at the loading end of the second conveyor line. Simultaneously, the clamping members B1 and B2 of the second clamping assembly grab battery cells C3 and C4 that have reached the unloading end of the first conveyor line 110. After the battery cells are grabbed and placed, the first drive unit 210 drives the lifting platform 230 to rise to a safe height.

[0044] Subsequently, the second drive unit 220 drives the rotating beam 240 to rotate 180° counterclockwise to prevent the equipment's cables from being twisted. During this process, the first clamping assembly 260 switches to the position above the unloading end of the first conveyor line 110, and the second clamping assembly 260 switches to the position above the loading end of the second conveyor line 120. Under the action of the transmission assembly 250, the first clamping assembly 260 rotates 90° counterclockwise, and the second clamping assembly 260 rotates 90° clockwise. At this time, the positions of the clamping parts A1 and A2 of the first clamping assembly 260, the clamping parts B1 and B2 of the second clamping assembly 260, and the battery cells C3 and C4 are as follows: Figure 9 As shown; subsequently, the first drive unit 210 drives the lifting platform 230 to descend, bringing the first clamping assembly 260 close to the unloading end of the first conveyor line 110. Clamping members A1 and A2 of the first clamping assembly 260 prepare to grab the battery cells C5 and C6 that subsequently arrive at the unloading end of the first conveyor line 110. Clamping members B1 and B2 of the second clamping assembly 260 place battery cells C3 and C4 at the loading end of the second conveyor line. After the battery cells are grabbed and placed, the first drive unit 210 drives the lifting platform 230 to rise to a safe height. The second drive unit 220 drives the rotating beam 240 to rotate 180° clockwise to transfer battery cells C5 and C6, as well as the subsequent battery cell 130.

[0045] By repeatedly performing the above actions, each cell 130 on the first conveyor line 110 can be placed on the second conveyor line 120 in a strictly predetermined order.

[0046] In other processes where the arrangement order of the battery cells 130 is not strictly required, the second meshing teeth of the first drive wheel 251 and the second meshing teeth of the second drive wheel 253 can both mesh with the first meshing teeth on the inner surface of the drive belt 254, or the second meshing teeth of the first drive wheel 251 and the second meshing teeth of the second drive wheel 253 can both mesh with the first meshing teeth on the outer surface of the drive belt 254. The specific choice can be made based on the actual situation.

[0047] In optional implementations of this application, such as Figure 5 and Figure 6As shown, the transmission belt 254 includes a belt body 2543, a first connecting member 2542, and a second connecting member 2541. The belt body 2543 is elongated and has a first end and a second end that are disposed opposite to each other. The first connecting member 2542 is fixedly disposed at the first end of the belt body 2543, and the second connecting member 2541 is fixedly disposed at the second end of the belt body 2543. The first connecting member 2542 and the second connecting member 2541 are detachably connected. Through the detachable connection between the first connecting member 2542 and the second connecting member 2541, the transmission belt 254 can be quickly replaced without disassembling the components. When the transmission belt 254 needs to be replaced, it can be removed simply by disassembling the first connecting member 2542 and the second connecting member 2541. The entire process does not require disassembling the overall equipment structure, greatly shortening maintenance time and reducing downtime losses. Furthermore, the detachable structure allows the length of the transmission belt 254 to be flexibly adjusted according to actual needs. The first connector 2542 and the second connector 2541 can be fixed together by bolts, so that the tension of the transmission belt 254 can be adjusted by adjusting the position of the nut.

[0048] In other alternative embodiments, the first connector 2542 and the second connector 2541 may also be connected in a detachable manner by means of elastic claws and slots, or they may be connected in a detachable manner by means of quick-connect or metal buckles.

[0049] In optional implementations of this application, such as Figure 5 and Figure 6 As shown, a slide rail 255 is provided on the rotating beam 240; a first slider that mates with the slide rail 255 is provided on the first connecting member 2542, and a second slider that mates with the slide rail 255 is provided on the second connecting member 2541. The first slider and the second slider are slidably connected to the slide rail 255. By providing the slide rail 255 and the first slider slidably connected to the slide rail 255 on the first connecting member 2542 and the second slider slidably connected to the slide rail 255 on the second connecting member 2541, guide support is provided for both ends of the transmission belt 254, ensuring the running accuracy of the transmission belt 254; at the same time, it makes the movement of the transmission belt 254 smoother, reduces component wear, and extends the service life of the transmission assembly 250.

[0050] In optional implementations of this application, such as Figure 5 and Figure 6As shown, the transmission assembly 250 also includes a second guide wheel 256 and a third guide wheel 257 rotatably disposed on the side of the rotating beam 240. The second guide wheel 256 and the third guide wheel 257 abut against the transmission belt 254 so that the portion of the transmission belt 254 located between the second guide wheel 256 and the third guide wheel 257 extends along the length direction of the rotating beam 240. The first connector 2542 and the second connector 2541 are located on the portion of the transmission belt 254 located between the second guide wheel 256 and the third guide wheel 257.

[0051] In this embodiment, the second guide wheel 256 and the third guide wheel 257 are arranged to form a constraint by abutting against the transmission belt 254, so that the transmission belt 254 of the part where the first connector 2542 and the second connector 2541 are located can extend strictly along the length direction of the rotating beam 240, ensuring that the first connector 2542 and the second connector 2541 are always in a stable stress state, and avoiding the problem of the slider and the slide rail 255 getting stuck due to the bending of the transmission belt 254.

[0052] In optional implementations of this application, such as Figures 2 to 6 As shown, each clamping assembly 260 also includes a mounting plate 261 and a connecting shaft. Each clamping member 262 of each clamping assembly 260 is spaced apart on the lower surface of the corresponding mounting plate 261, and the connecting shaft of each clamping assembly 260 is fixedly mounted on the upper surface of the corresponding mounting plate 261. The connecting shafts of two clamping assemblies 260 are rotatably mounted on the rotating beam 240 via bearings. The connecting shaft of the first clamping assembly 260 is connected to the first transmission wheel 251, and the connecting shaft of the second clamping assembly 260 is connected to the second transmission wheel 253. The rotatable connection between the connecting shaft and the rotating beam 240 via bearings ensures that the clamping assembly 260 moves synchronously with the rotating beam 240 during its revolution, and also provides flexible rotational support for the rotation of the clamping assembly 260, reducing frictional resistance during rotation and making the rotation of the clamping assembly 260 driven by the transmission wheel smoother, avoiding jamming. The mounting plate 261 provides a mounting base for the multiple clamping members 262, ensuring the stability of each clamping member 262. In addition, the mounting plate 261 is directly connected to the transmission wheel via the connecting shaft, which shortens the power transmission path, reduces power loss, and ensures that the rotation of the transmission wheel can be transmitted to the clamping assembly 260 quickly and accurately, so that the reversing action of the battery cell 130 can be more timely and accurate, and avoids misplacement of the battery cell 130 due to power transmission delay.

[0053] In optional implementations of this application, such as Figures 2 to 4As shown, the battery cell conveying equipment also includes a turntable 270 and multiple support rods 280; the turntable 270 can be fixedly installed at the output end of the second drive unit 220 by means of screw connection or snap connection, and the two ends of each support rod 280 are fixed on the turntable 270 and the rotating beam 240 respectively; the multiple support rods 280 are evenly distributed on the outside of the drive wheel 252 so as to evenly support the rotating beam 240.

[0054] In this embodiment, the rotating beam 240, as the core component supporting the transmission assembly 250 and the clamping assembly 260, must bear the weight of the clamping assembly 260 and the battery cell 130 during operation, while also withstanding the centrifugal force and torque generated by the combined revolution and rotation. The multiple evenly distributed support rods 280 of this application uniformly transmit the weight and force of the rotating beam 240 to the turntable 270, and then through the turntable 270 to the second drive component 220, effectively dispersing local stress and preventing deformation of the rotating beam 240 due to concentrated stress. Simultaneously, the evenly distributed support rods 280 can counteract the centrifugal force generated during rotation, reducing the vibration amplitude of the rotating beam 240, making its revolution smoother, and preventing meshing misalignment or transmission ratio deviation caused by vibration. This ensures the precise movement of the clamping assembly 260 and makes the transfer and reversal of the battery cell 130 more reliable.

[0055] In optional embodiments of this application, the first driving component 210 may be a telescopic cylinder such as a pneumatic cylinder or an electric cylinder, or a combination of gears, racks and pinions and a motor; the second driving component 220 may be a motor or a hydraulic motor, etc.

[0056] In optional implementations of this application, such as Figure 5 and Figure 6As shown, the transmission assembly 250 also includes two first guide wheels 258. The two first guide wheels 258 are respectively located on two support rods 280 and on both sides of the drive wheel 252. The two first guide wheels 258 abut against the transmission belt 254 so that at least half of the drive wheel 252 meshes with the transmission belt 254. The two first guide wheels 258 are symmetrically distributed on both sides of the drive wheel 252. By abutting against the transmission belt 254, they form a three-point positioning constraint on the transmission belt 254, allowing the transmission belt 254 to tightly fit the outer surface of the drive wheel 252. This ensures that at least half of the tooth surface of the drive wheel 252 meshes with the transmission belt 254, significantly increasing the meshing area. This not only improves the transmission's load-bearing capacity and effectively transmits driving torque, but also prevents excessive tooth surface wear due to an insufficient meshing area. Furthermore, it ensures that the meshing relationship between the transmission belt 254 and the drive wheel 252 remains stable, preventing disengagement or slippage. Furthermore, the improved meshing stability allows the clamping assembly 260 to precisely rotate 90° when the rotating beam 240 revolves 180°, ensuring that the orientation of the battery cell 130 on the second conveyor line 120 strictly conforms to the process requirements and preventing directional deviations of the battery cell 130 from affecting subsequent processes. In addition, the first guide wheel 258, mounted on the support rod 280, reduces redundant components in the equipment, lowers assembly difficulty, and facilitates subsequent inspection and maintenance, further enhancing the practicality and operational reliability of the equipment.

[0057] In optional implementations of this application, such as Figure 2 and Figure 4 As shown, the cell conveying equipment also includes a bracket 291; a guide rod 292 extending vertically is provided on the bracket 291, and a sliding sleeve matching the guide rod 292 is provided on the lifting seat 230, with the sliding sleeve slidably connected to the guide rod 292; the first driving member 210 is fixedly mounted on the bracket 291. The sliding fit structure between the guide rod 292 and the sliding sleeve provides guiding constraints for the lifting movement of the lifting seat 230, ensuring that the lifting seat 230 can move smoothly and strictly in the vertical direction, avoiding deviation; at the same time, the sliding connection between the sliding sleeve and the guide rod 292 reduces the frictional resistance of the lifting movement, making the first driving member 210 drive the lifting seat 230 to rise and fall more smoothly and respond more quickly, and enabling rapid adjustment of the height of the clamping assembly 260.

[0058] In optional implementations of this application, such as Figure 2 and Figure 3As shown, the clamping member 262 includes a double-headed cylinder 2621 and two grippers 2622. The double-headed cylinder 2621 is used to drive the two grippers 2622 to move closer together to clamp the battery cell 130 or to move further apart to release the battery cell 130. In this embodiment, the double-headed cylinder 2621 can provide symmetrical and uniform clamping force, thereby ensuring that the battery cell 130 is subjected to balanced force when clamped, which can protect the battery cell 130; at the same time, the double-headed cylinder 2621 also has the characteristic of fast response speed.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
