Description

Technical Field

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

[0002] After processing, the battery packs need to be loaded into the energy storage system's container. Currently, this loading process typically relies on manual hoisting or forklift transport to move the processed battery packs from the end of the production line to a temporary storage station near the container. Dedicated packing equipment then retrieves the battery packs from this station and packs them into containers. After the packing equipment removes the battery packs from the temporary storage station, the next battery pack is retrieved manually or by forklift. However, because the battery pack processing line is far from the container, the time it takes for the packing equipment to pack the battery packs into the container is shorter than the time it takes to transport the packs to the temporary storage station. This results in frequent downtime for the packing equipment, leading to low production efficiency. Utility Model Content

[0003] The purpose of this application is to provide a battery pack feeding device to solve the technical problem that in the prior art, the time spent by the packing equipment to pack the battery pack into the container is shorter than the time to send the battery pack to the temporary storage station, which causes the packing equipment to frequently stop waiting and results in low production efficiency.

[0004] In a first aspect, this application provides a battery pack feeding device, including: a material rack, a transport mechanism, a lifting mechanism, and a straightening mechanism; The rack is used to store the upper and lower battery packs; The transport mechanism is used to move the material rack from the picking position to below the temporary storage position; The lifting and sizing mechanisms are located at the temporary storage station; The lifting mechanism is configured to first lift the upper battery pack of the rack located below the temporary storage station to the temporary storage station. The straightening mechanism receives the upper battery pack and straightens it. Then the lifting mechanism moves down to the rack to lift the lower battery pack. After the upper battery pack in the temporary storage station is taken away by the packing equipment, the lifting mechanism lifts the lower battery pack to the temporary storage station. The straightening mechanism receives the lower battery pack and straightens it. The transport mechanism is also configured to return to the retrieval position with the material rack after the lifting mechanism lifts the lower battery pack.

[0005] The double-layer rack system provides both upper and lower battery packs simultaneously. Through the coordinated operation of the lifting and aligning mechanisms, the temporary storage station can supply battery packs to the packing equipment almost uninterruptedly, enabling parallel loading and packing operations. Simultaneously, after the lifting mechanism completes lifting the lower battery pack, the transport mechanism immediately returns to the picking position with the empty rack. During the time between the transport mechanism's return for picking and the return of a new batch of battery packs, the packing equipment can remove the lower battery packs from the temporary storage station and pack them. The packing equipment does not need to wait, allowing transport and packing to occur concurrently, thus improving overall production efficiency. Compared to the traditional method of transporting only one battery pack at a time, the double-layer rack structure doubles the transport capacity per trip, significantly improving transport efficiency.

[0006] In an optional embodiment, the rack includes a support and at least two support components disposed on the support. Each support component includes a first support member and a second support member located above the first support member. The first support member of each support component is used to support the lower battery pack, and the second support member of each support component is used to support the upper battery pack. The first support and the second support are connected by a linkage mechanism, so that when there is no battery pack on the rack, the first support is in a waiting support state to support the lower battery pack, and the second support is in a avoidance state to avoid the movement path of the battery pack. When the first support component supports the lower battery pack, the first support component drives the second support component to switch from the avoidance state to the waiting support state, which is waiting to support the upper battery pack, through the linkage mechanism.

[0007] Each support assembly includes a first support for supporting the lower battery pack and a second support for supporting the upper battery pack, connected by a linkage mechanism. In the unloaded state, the first support protrudes to receive the battery pack, while the second support retracts into the mounting frame, clearing a path for battery pack placement and removal. Once the lower battery pack is placed on the first support and flattened, the linkage mechanism drives the second support to automatically flip out, entering a waiting state to receive the upper battery pack. This linkage mechanism enables automatic switching of the rack's support state, ensuring unobstructed movement of the battery packs in the unloaded state and avoiding interference. Furthermore, it automatically prepares the upper workstation after placing the lower battery pack, simplifying the operation process and achieving automated material preparation without the need for an additional power source or control system. The ingenious structure ensures high reliability.

[0008] In an optional embodiment, the linkage mechanism includes a linkage rod and a counterweight, and the bearing assembly also includes a fixed frame mounted on the bracket. The first support and the second support are both hinged to the fixed frame via a transverse axis. The lower end of the linkage rod is provided with an oblong hole extending along its own length. The first end of the first support member is provided with a driven shaft, which is inserted into the oblong hole. The upper end of the linkage rod is hinged to the first end of the second support member, and the counterweight is provided at the first end of the second support member. When there is no battery pack on the first support and the second support, the second end of the first support protrudes out of the fixed frame and is in a waiting support state, while the second end of the second support is located inside the fixed frame and is in a clearance state. As the lower battery pack gradually falls onto the second end of the first support member, the first support member rotates from the waiting support state to the horizontal state, and drives the linkage rod to lift upward through the driven shaft, thereby driving the second support member to rotate, so that the second support member rotates from the avoidance state to the waiting support state. As the upper battery pack gradually falls onto the second end of the second support, the second support rotates from the waiting support state to the horizontal state.

[0009] The linkage mechanism includes a linkage rod and a counterweight. The lower end of the linkage rod has a slotted hole that engages with the driven shaft of the first support member, while the upper end of the linkage rod is hinged to the first end of the second support member. When the first support member rotates to a horizontal position due to carrying the battery pack, the movement of the driven shaft within the slotted hole pushes the linkage rod upwards, thereby causing the second support member to flip out. The counterweight serves to automatically reset the second support member to a clearance position using gravity after the upper battery pack is removed; and when the lower battery pack is also removed, it drives the entire system to fully reset to its initial no-load state. Utilizing the battery pack's own weight as a power source enables precise and automatic switching and reset of the support member's state. The slotted hole provides the necessary stroke and cushioning, resulting in smoother operation. The entire system requires no sensors or electric components, reducing manufacturing costs and improving reliability and durability.

[0010] In an optional embodiment, the lifting mechanism includes two sets of lifting assemblies arranged opposite each other, with a space between the two sets of lifting assemblies for the transport mechanism and the rack to pass through. Each lifting assembly includes a frame, a lifting frame, a lifting drive component, a first drive unit, and a load-bearing component, wherein: The lifting drive is mounted on the frame, the lifting frame is slidably connected to the frame vertically, the lifting drive is connected to the lifting frame and is used to drive the lifting frame to lift vertically, the load-bearing component is slidably mounted on the lifting frame horizontally, and the first driver is used to drive the load-bearing component to extend horizontally out of the lifting frame or retract. When the transport mechanism and the rack move to the area below the temporary storage station, the lifting drive unit drives the lifting frame and the carrier to descend to the side of the battery pack on the rack. The first drive unit extends the carrier to the area below the battery pack, and the lifting drive unit drives the lifting frame and the carrier to rise, lifting the battery pack to the temporary storage station.

[0011] The lifting mechanism comprises two symmetrically distributed lifting assemblies, with a passageway between them for the transport mechanism and the material rack. Each lifting assembly includes a lifting frame driven by a lifting drive, and a load-bearing component horizontally slidably mounted on it. The lifting frame is slidably connected to the frame via a second slide rail. During operation, the load-bearing component first descends and enters from the side of the battery pack, then extends horizontally to support the battery pack, and finally lifts the entire assembly to complete the loading action. The two lifting assemblies are positioned opposite each other to lift the battery pack synchronously and smoothly. Furthermore, the lateral insertion and lifting motion after descent effectively avoids structural interference from the material rack itself, achieving precise and stable loading and unloading.

[0012] In an optional embodiment, the straightening mechanism includes two sets of straightening components arranged opposite each other on both sides of the temporary storage station. The two sets of straightening components are respectively located above two sets of lifting components. Each straightening component includes a temporary storage block, a straightening element, a second driver, and a third driver, wherein: The second driver is used to drive the temporary storage block to extend horizontally to the temporary storage station or retract it. The temporary storage block is used to receive the battery pack sent to the temporary storage station by the lifting mechanism. The alignment element is located above the temporary storage tray side, and the third actuator is used to drive the alignment element to extend or retract horizontally to align the battery pack held by the temporary storage tray.

[0013] The aligning mechanism also includes two symmetrically distributed aligning components, each corresponding to a specific one above the lifting assembly. The aligning components consist of a temporary storage block driven by a second driver and an aligning element driven by a third driver. After the lifting mechanism raises the battery pack to a predetermined height, the temporary storage block extends horizontally to receive the battery pack, allowing the lifting mechanism to descend for the next operation. Subsequently, the aligning element extends from the side to clamp or straighten the battery pack, ensuring it is in a position that the packing equipment can accurately grasp. Separating the temporary storage and aligning functions and controlling them with independent drivers achieves functional modularization and optimized action timing. The lifting mechanism eliminates the need for prolonged lifting and stopping, improving equipment utilization; the aligning action is performed after temporary storage, ensuring the accuracy of the battery pack's position, thereby guaranteeing the positioning accuracy and success rate of subsequent packing operations.

[0014] In an optional implementation, each lifting assembly has two carriers, and the two carriers of each lifting assembly are located on the outer sides of the two ends of the temporary storage block on the same side. The lifting frame is provided with two first support seats that extend horizontally toward the temporary storage position. The two carriers are slidably connected to the two first support seats through the first slide rails, and the first driver is fixedly connected to the first support seats.

[0015] Each lifting assembly features two independent support members positioned on the outer ends of the temporary storage block on the same side. These support members are mounted on a first support seat extending from the lifting frame via a first slide rail. These two support members provide additional support points and improved stability when lifting the battery pack, preventing it from swaying due to large spans. Simultaneously, the end of the first support seat does not protrude from the fixing frame of the support assembly on the rack, ensuring that the lifting mechanism will not collide with the fixing frame during descent and movement, thus enhancing operational safety.

[0016] In an optional implementation, each organizing component further includes a slide plate and a second support base, with two temporary storage blocks spaced apart on the slide plate; The second support is connected to the frame, the slide plate is slidably connected to the second support via the third slide rail, and the second drive is fixed to the second support.

[0017] Two temporary storage blocks are fixed at intervals on the same sliding plate, which is mounted on a second support base via a third slide rail. Driven by a second actuator, the two temporary storage blocks always move synchronously, jointly supporting both ends of the battery pack and ensuring stable support. Structurally, this design reduces the number of drive components, simplifies the mechanism, and lowers control and maintenance costs.

[0018] In an optional implementation, the regulating mechanism further includes a third support and a guide rod; The third support is mounted on the frame. The aligner is slidably mounted on the third support via two guide rods. The third driver is fixed to the third support, and the output end of the third driver passes through the third support and is fixedly connected to the aligner.

[0019] The alignment component is mounted on the third support via two guide rods and is driven by the third actuator to slide horizontally. The dual guide rods provide extremely high motion rigidity and guiding accuracy for the extension and retraction of the alignment component, effectively preventing deflection or jamming during operation and ensuring the accuracy and reliability of the alignment action.

[0020] In an optional implementation, two temporary storage stations are provided, each equipped with a lifting mechanism and a regulating mechanism, wherein: The rack is configured to store two layers of first battery packs, each layer including two first battery packs. After the transport mechanism moves the rack to below the two temporary storage positions, two lifting mechanisms are configured to lift the two first battery packs on the same layer to the corresponding temporary storage positions. Two straightening mechanisms are configured to receive and straighten the two first battery packs respectively. The rack is also configured to store two layers of second battery packs, each layer including one second battery pack. After the transport mechanism moves the rack to below the two temporary storage stations, two lifting mechanisms are configured to lift a single second battery pack to the two temporary storage stations, and two straightening mechanisms are configured to receive and straighten a single second battery pack.

[0021] The battery pack loading device is equipped with two complete temporary storage stations, lifting mechanisms, and straightening mechanisms. When processing the first battery pack (short battery pack), two are placed on each shelf, and the two mechanisms work independently, processing two battery packs simultaneously. When processing the second battery pack (long battery pack), one is placed on each shelf. The two lifting mechanisms work together to support both ends of the battery pack, and the two straightening mechanisms work together to straighten it, achieving compatibility of the battery pack loading device with battery packs of different sizes. Through flexible collaborative control, the production capacity can be doubled when producing the first battery pack, and the capacity of the battery pack loading device can be fully utilized when producing the second battery pack, greatly improving the applicability of the battery pack loading device.

[0022] In an optional implementation, the transport mechanism can lift two racks. The transport mechanism is configured to move to a position below the racks located at the picking position, then lift and support the racks. The transport mechanism is also configured to move the racks to a temporary storage position, then lower and detach the racks from the racks.

[0023] After receiving a rack at the picking position, the transport mechanism moves to the temporary storage station, places the rack there, and then returns to the picking position to pick up the next rack. The transport mechanism then returns to the temporary storage station, removes the previous empty rack, moves forward slightly, places another rack with a full battery pack at the temporary storage station, and then returns to the picking position to receive a new full rack and place an empty rack down, forming a continuous and smooth material flow, further improving production efficiency.

[0032] The present application will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0033] The specific structure is as follows: Figures 1 to 13 As shown.

[0034] This embodiment provides a battery pack loading device, including: a rack 1, a transport mechanism, a lifting mechanism 3, and a straightening mechanism 4; the rack 1 is used to store upper and lower battery packs; the transport mechanism is used to transport the rack 1 from the picking position to below the temporary storage station 5; the lifting mechanism 3 and the straightening mechanism 4 are located at the temporary storage station 5; the lifting mechanism 3 is configured to first lift the upper battery pack of the rack 1 located below the temporary storage station 5 to the temporary storage station 5, the straightening mechanism 4 receives the upper battery pack and straightens it, then the lifting mechanism 3 moves down to the rack 1 to lift the lower battery pack, when the upper battery pack at the temporary storage station 5 is taken away by the packing equipment, the lifting mechanism 3 lifts the lower battery pack to the temporary storage station 5, the straightening mechanism 4 receives the lower battery pack and straightens it; the transport mechanism is also configured to return to the picking position with the rack 1 after the lifting mechanism 3 lifts the lower battery pack.

[0035] In this embodiment, the double-layer rack 1 provides both upper and lower battery packs at once. The coordinated action of the lifting mechanism 3 and the straightening mechanism 4 ensures that the temporary storage station 5 can supply battery packs to the packing equipment almost uninterruptedly, achieving parallel operation of loading and packing. Simultaneously, after the lifting mechanism 3 completes lifting the lower battery pack, the transport mechanism can immediately return to the picking position with the empty rack 1. During the time between the transport mechanism returning to pick up the pack and transporting a new batch of battery packs, the packing equipment can remove the lower battery packs from the temporary storage station 5 and pack them. The packing equipment does not need to wait, allowing transport and packing to proceed simultaneously, improving overall production efficiency. Compared to the traditional method of transporting only one battery pack at a time, the double-layer rack 1 doubles the transport capacity of the transport mechanism, improving transport efficiency.

[0036] In this embodiment, the transportation mechanism can be an AGV (Automated Guided Vehicle), a conveyor line, an autonomous mobile robot, or an unmanned forklift, etc.

[0037] In the optional technical solution of this embodiment, the rack 1 includes a support 6 and at least two supporting components 7 disposed on the support 6. Each supporting component 7 includes a first support member 8 and a second support member 9 located above the first support member 8. The first support member 8 of each supporting component 7 is used to support the lower battery pack, and the second support member 9 of each supporting component 7 is used to support the upper battery pack. The first support member 8 and the second support member 9 are connected by a linkage mechanism 10, so that when there is no battery pack on the rack 1, the first support member 8 is in a waiting support state for supporting the lower battery pack, and the second support member 9 is in a avoidance state to avoid the movement path of the battery pack. When the first support member 8 supports the lower battery pack, the first support member 8 drives the second support member 9 to switch from the avoidance state to the waiting support state for supporting the upper battery pack through the linkage mechanism 10.

[0038] In this embodiment, each supporting component 7 includes a first supporting member 8 for supporting the lower battery pack and a second supporting member 9 for supporting the upper battery pack, and the two are connected by a linkage mechanism 10. In the unloaded state, the first supporting member 8 protrudes to prepare to receive the battery pack, while the second supporting member 9 retracts into the fixing frame 13 to clear the path for the placement and removal of the battery pack. When the lower battery pack is placed on the first supporting member 8 and flattened, the linkage mechanism 10 drives the second supporting member 9 to automatically flip out and enter the waiting state to receive the upper battery pack. The linkage mechanism 10 realizes the automatic switching of the supporting state of the rack 1, which not only ensures the unobstructed movement path of the battery pack when unloaded and avoids interference, but also automatically prepares the upper station after the lower battery pack is placed, simplifying the operation process, realizing automated material preparation, requiring no additional power source or control, with ingenious structure and high reliability.

[0039] In the optional technical solution of this embodiment, the linkage mechanism 10 includes a linkage rod 11 and a counterweight 12, and the bearing assembly 7 also includes a fixed frame 13 mounted on the bracket 6. The first support member 8 and the second support member 9 are both hinged to the fixed frame 13 via a horizontal shaft 14. The lower end of the linkage rod 11 has an oblong hole 15 extending along its own length direction. The first end of the first support member 8 is provided with a driven shaft 16, which is inserted into the oblong hole 15. The upper end of the linkage rod 11 is hinged to the first end of the second support member 9, and the counterweight 12 is provided at the first end of the second support member 9. When the first support member 8 and the second support member 9 are on When there is no battery pack, the second end of the first support member 8 protrudes from the fixing frame 13 and is in a waiting support state, while the second end of the second support member 9 is located inside the fixing frame 13 and is in a clearance state. When the lower battery pack gradually falls onto the second end of the first support member 8, the first support member 8 rotates from the waiting support state to a horizontal state, and drives the linkage rod 11 to rise upward through the driven shaft 16, thereby driving the second support member 9 to rotate, so that the second support member 9 rotates from the clearance state to the waiting support state. When the upper battery pack gradually falls onto the second end of the second support member 9, the second support member 9 rotates from the waiting support state to a horizontal state.

[0040] In this embodiment, the linkage mechanism 10 includes a linkage rod 11 and a counterweight 12. The lower end of the linkage rod 11 has a slotted hole 15 that engages with the driven shaft 16 of the first support member 8, while the upper end of the linkage rod 11 is hinged to the first end of the second support member 9. When the first support member 8 rotates to a horizontal position due to carrying the battery pack, the movement of the driven shaft 16 within the slotted hole 15 pushes the linkage rod 11 upward, thereby causing the second support member 9 to flip out. The counterweight 12 functions to automatically reset the second support member 9 to a clearance state using gravity after the upper battery pack is removed; and to completely reset the entire system to its initial unloaded state when the lower battery pack is also removed. By using the weight of the battery pack as a power source, precise and automatic switching and reset of the support member's state are achieved. The slotted hole 15 provides the necessary stroke and cushioning, making the movement smoother. The entire system requires no sensors or electric components, which not only reduces manufacturing costs but also improves reliability and durability.

[0041] In the optional technical solution of this embodiment, the lifting mechanism 3 includes two sets of lifting components 17 arranged opposite to each other. There is a space between the two sets of lifting components 17 for the transport mechanism and the material rack 1 to pass through. Each set of lifting components 17 includes a frame 18, a lifting frame 19, a lifting drive component 20, a first driver 21, and a carrier component 22. The lifting drive component 20 is mounted on the frame 18, and the lifting frame 19 is slidably connected to the frame 18 vertically. The lifting drive component 20 is drively connected to the lifting frame 19 and is used to drive the lifting frame 19. The vertical lifting mechanism allows the carrier 22 to slide horizontally on the lifting frame 19. The first driver 21 drives the carrier 22 to extend horizontally out of the lifting frame 19 or retract. When the transport mechanism and the material rack 1 move to below the temporary storage station 5, the lifting drive 20 lowers the lifting frame 19 and the carrier 22 to below the side of the battery pack on the material rack 1. The first driver 21 extends the carrier 22 below the battery pack. The lifting drive 20 then raises the lifting frame 19 and the carrier 22 to lift the battery pack to the temporary storage station 5.

[0042] In this embodiment, the lifting mechanism 3 includes two symmetrically distributed lifting components 17, with a passageway in the middle for the transport mechanism and the material rack 1 to pass through. Each lifting component 17 includes a lifting frame 19 driven by a lifting drive component 20, and a carrier component 22 horizontally slidably mounted on it. The lifting frame 19 is movably connected to the frame 18 via a second slide rail 35. During operation, the carrier component 22 first descends and enters from the side of the battery pack below it, then extends horizontally to support the battery pack, and finally lifts the entire component to complete the picking action. The two lifting components 17 are arranged opposite each other to lift the battery pack synchronously and smoothly. At the same time, the action process of descending and then extending from the side to lift and raise effectively avoids structural interference from the material rack 1 itself, achieving precise and stable picking and placing.

[0043] In this embodiment, the specific form of the lifting drive component 20 is not limited; any mechanism capable of achieving stable and controllable linear lifting motion can be used. For example, it can be a ball screw mechanism, electric cylinder, hydraulic cylinder, pneumatic cylinder, gear and rack mechanism, sprocket and chain mechanism, or synchronous belt and pulley mechanism, etc.

[0044] In this embodiment, the lifting frame 19 is provided with a mounting plate 2, and the lifting drive mechanism is connected to the mounting plate 2, which is convenient to install and has stable transmission.

[0045] In the optional technical solution of this embodiment, the straightening mechanism 4 includes two sets of straightening components 23 arranged opposite to each other on both sides of the temporary storage station 5. The two sets of straightening components 23 are respectively located above the two sets of lifting components 17. The straightening component 23 includes a temporary storage block 24, a straightening element 25, a second driver 26 and a third driver 27, wherein: the second driver 26 is used to drive the temporary storage block 24 to extend horizontally to the temporary storage station 5 or retract it, and the temporary storage block 24 is used to receive the battery pack sent to the temporary storage station 5 by the lifting mechanism 3; the straightening element 25 is located above the temporary storage block 24, and the third driver 27 is used to drive the straightening element 25 to extend horizontally or retract it, so as to straighten the battery pack received by the temporary storage block 24.

[0046] In this embodiment, the aligning mechanism 4 also includes two symmetrically distributed aligning components 23, each located above the lifting assembly 17. The aligning component 23 includes a temporary storage block 24 driven by a second driver 26 and an aligning element 25 driven by a third driver 27. After the lifting mechanism 3 lifts the battery pack to a predetermined height, the temporary storage block 24 extends horizontally to receive the battery pack, allowing the lifting mechanism 3 to descend for the next operation. Subsequently, the aligning element 25 extends from the side to clamp or straighten the battery pack, ensuring it is in a position that the packing equipment can accurately grasp. Separating the temporary storage and aligning functions and controlling them with independent drivers achieves functional modularization and optimized action timing. The lifting mechanism 3 does not require long periods of waiting, improving equipment utilization; the aligning action is performed after temporary storage, ensuring the accuracy of the battery pack's position, thereby guaranteeing the positioning accuracy and success rate of subsequent packing operations.

[0047] In this embodiment, the specific forms of the first driver 21, the second driver 26, and the third driver 27 are not limited; they can be any power element capable of driving the corresponding components to perform controllable linear motion. For example, cylinders, hydraulic cylinders, electric linear actuators, servo cylinders, linear motors, or electric slide modules, etc.

[0048] In the optional technical solution of this embodiment, each lifting assembly 17 has two carriers 22. The two carriers 22 of each lifting assembly 17 are located on the outer sides of the two ends of the temporary storage block 24 on the same side. The lifting frame 19 is provided with two first support seats 28 extending horizontally toward the temporary storage station 5. The two carriers 22 are movably connected to the two first support seats 28 through the first slide rail 29. The first driver 21 is fixedly connected to the first support seat 28.

[0049] In this embodiment, two independent support members 22 are provided on each lifting assembly 17, and their positions are located on the outer sides of the temporary storage block 24 on the same side. The support members 22 are mounted on the first support seat 28 extending from the lifting frame 19 via the first slide rail. The two support members 22 provide additional support points and better stability when lifting the battery pack, preventing the battery pack from swaying due to large spans. At the same time, the end of the first support seat 28 does not protrude from the fixing frame 13 of the support assembly 7 on the rack 1, ensuring that the lifting mechanism 3 will not collide with the fixing frame 13 during descent and movement, making operation safer.

[0050] In the optional technical solution of this embodiment, each regularization component 23 further includes a slide plate 30 and a second support base 31. Two temporary storage blocks 24 are spaced apart on the slide plate 30. The second support base 31 is connected to the frame 18. The slide plate 30 is movably connected to the second support base 31 through a third slide rail 32. The second driver 26 is fixed to the second support base 31.

[0051] In this embodiment, two temporary storage blocks 24 are fixed at intervals on the same sliding plate 30. The sliding plate 30 is mounted on the second support base 31 via a third slide rail and is driven uniformly by a second driver 26, ensuring that the two temporary storage blocks 24 always move synchronously and jointly support both ends of the battery pack, thus guaranteeing stable support. Structurally, this reduces the number of driving components, simplifies the mechanism, and lowers control and maintenance costs.

[0052] In the optional technical solution of this embodiment, the straightening mechanism 4 further includes a third support base 33 and a guide rod 34; the third support base 33 is mounted on the frame 18, the straightening element 25 is slidably mounted on the third support base 33 through the two guide rods 34, the third driver 27 is fixed to the third support base 33, and the output end of the third driver 27 passes through the third support base 33 and is fixedly connected to the straightening element 25.

[0053] In this embodiment, the alignment member 25 is mounted on the third support base 33 via two guide rods 34 and is driven by the third driver 27 to slide horizontally. The dual guide rods 34 provide extremely high motion rigidity and guiding accuracy for the extension and retraction of the alignment member 25, effectively preventing the alignment member 25 from deflecting or jamming during operation, and ensuring the accuracy and reliability of the alignment action.

[0054] In the optional technical solution of this embodiment, there are two temporary storage stations 5. Each temporary storage station 5 is equipped with a lifting mechanism 3 and a straightening mechanism 4. The rack 1 is configured to store two layers of first battery packs 36, with each layer including two first battery packs 36. After the transport mechanism moves the rack 1 to below the two temporary storage stations 5, the two lifting mechanisms 3 are configured to lift the two first battery packs 36 of the same layer to the corresponding temporary storage station 5. The two straightening mechanisms 4 are configured to receive and straighten the two first battery packs 36 respectively. The rack 1 is also configured to store two layers of second battery packs, with each layer including one second battery pack. After the transport mechanism moves the rack 1 to below the two temporary storage stations 5, the two lifting mechanisms 3 are configured to lift a single second battery pack to the two temporary storage stations 5. The two straightening mechanisms 4 are configured to receive and straighten the single second battery pack.

[0055] In this embodiment, the battery pack loading device is equipped with two complete temporary storage stations 5, lifting mechanisms 3, and straightening mechanisms 4. When processing the first battery pack 36 (short battery pack), two are placed on each layer of the rack 1, and the two mechanisms work independently, processing two battery packs simultaneously. When processing the second battery pack (long battery pack), one is placed on each layer of the rack 1, the two lifting mechanisms 3 work together to lift both ends of one battery pack, and the two straightening mechanisms 4 work together to straighten it, achieving compatibility of the battery pack loading device with battery packs of different sizes. Through flexible collaborative control, the production capacity can be doubled when producing the first battery pack 36, and the capacity of the battery pack loading device can be fully utilized when producing the second battery pack, greatly improving the applicability of the battery pack loading device.

[0056] In the optional technical solution of this embodiment, the transport mechanism can lift two material racks 1. The transport mechanism is configured to move to the material rack 1 below the material rack 1 located at the material picking position, then lift and support the material rack 1. The transport mechanism is also configured to move the material rack 1 to the temporary storage station 5, then lower the material rack 1 and detach it from the material rack 1.

[0057] In this embodiment, after receiving a material rack 1 at the material picking position, the transport mechanism moves to the temporary storage station 5, places the material rack 1 at the temporary storage station 5, and then returns to the material picking position to pick up the next material rack 1. Subsequently, the transport mechanism returns to the temporary storage station 5, takes away the previous empty material rack 1, steps forward, places another material rack 1 with a full battery pack at the temporary storage station 5, and then returns to the material picking position to receive a new full material rack 1 and place an empty material rack 1, forming a continuous and smooth material flow, which further improves production efficiency.

[0058] In this embodiment, the bracket 6 has two sets of opposite ends, one set of opposite ends is provided with a bearing component 7, and the other set of opposite ends is provided with a limiting component 37, which is used to limit the movement of the battery pack.

[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.
