Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a battery carrier and production equipment. Background Technology

[0002] In related technologies, during the production of battery cells, the battery cells have different posture requirements when they are processed at different workstations. For example, some workstations require the battery cells to be inverted, some workstations require the battery cells to be upright, and some workstations require the battery cells to be laid flat. This results in different postures of the battery cells between two workstations when they are processed at different workstations, so a battery flipping device is required.

[0003] Thus, not only does the battery flipping device require separate equipment cycle time and factory space, but its complex structure and numerous parts also increase production costs. Furthermore, with the high-speed and integrated development of battery cell equipment, the existing battery flipping device requires production cycle time, which reduces production efficiency and cannot meet the needs of high-speed and automated production. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, one objective of this application is to provide a battery carrier that, while moving batteries between multiple workstations, can simultaneously adjust the posture of individual battery cells without requiring a separate battery flipping device. This simplifies the structure, reduces production costs, and improves production efficiency, meeting the demands of high-speed, automated production.

[0005] This application further proposes a production equipment using the aforementioned battery carrier.

[0006] In a first aspect, this application provides a battery carrier, including: a drive base, a carrier body, and a drive assembly. The drive base is used to drive the carrier body to move between multiple workstations. The carrier body is movably mounted on the drive base and has a battery mounting position for fixing a single battery cell. The drive assembly is mounted on the drive base and is poweredly connected to the carrier body, and is used to drive the carrier body to switch between at least two positions. In different positions of the carrier body, the battery cell has a different posture above the drive base to adapt to the posture requirements of the battery cell during the processing of different workstations.

[0007] According to the battery carrier of the present application embodiment, by setting a driving component, the driving component can drive the carrier body to switch between at least two positions, so as to realize the attitude adjustment of the battery cells simultaneously during the process of the battery carrier transporting battery cells, and realize the battery cells to flip along with the carrier. Therefore, there is no need to set up a separate battery flipping device. On the one hand, it can improve the structure of the production equipment, increase the integration, and help reduce production costs. On the other hand, it can improve the production efficiency of the production equipment and adapt to the production cycle requirements of high-speed production mode without stopping the machine to adjust the attitude of the battery cells.

[0008] According to some embodiments of this application, the vehicle body is rotatably disposed on the drive seat, and the drive assembly is used to drive the vehicle body to rotate relative to the drive seat to switch between at least a first position and a second position. In the first position, the battery cell is in an upright posture, and in the second position, the battery cell is in a lying posture.

[0009] The above technical solution can simultaneously accommodate multiple process modes such as flat processing and vertical processing of battery cells without changing tooling or adjusting equipment. It can be compatible with at least two processing modes of flat and vertical battery cells, and the battery carrier has higher versatility and process adaptability.

[0010] According to some embodiments of this application, the drive assembly includes: a drive unit configured as a power source and used to actively drive the vehicle body to rotate relative to the drive seat, or the drive unit configured as a follower and used to passively drive the vehicle body to rotate relative to the drive seat.

[0011] In the above technical solution, by setting a drive unit that actively drives the movement of the carrier body, or by setting a drive unit that passively drives the movement of the carrier body, the carrier body can synchronously drive the seat to adjust the posture of the battery cells, thereby improving process compatibility and adaptability of the battery carrier. This allows multiple workstations with different battery cell postures to be integrated on the same production equipment, improving structural redundancy and facilitating the miniaturization and compact design of the production equipment.

[0012] According to some embodiments of this application, the drive assembly further includes a transmission unit, which is configured as any one of a gear and rack transmission group, a lead screw and nut transmission group, and a crank and slider transmission group, wherein the power output end of the transmission unit is connected to the vehicle body, and the power input end of the transmission unit is connected to the drive unit.

[0013] In the above technical solution, by setting the transmission part, in the embodiment where the drive part is configured as a power source, the smoothness of the vehicle body switching between multiple positions can be improved. In the embodiment where the drive part is configured as a follower, it can be adapted to the movement of the drive seat, and the synchronization and reliability of the following posture adjustment can also be improved.

[0014] According to some embodiments of this application, the drive unit is configured as a follower, the drive unit is constructed as a drive slider, the drive slider is connected to the power input end, the drive slider is slidably connected to the drive seat, and one end of the drive slider is provided with a cam bearing. A drive cam is provided at the work station where the battery cell attitude needs to be changed. The drive cam has a cam groove, and the cam bearing is provided in the cam groove so as to drive the carrier body to rotate according to the motion trajectory of the cam bearing defined by the cam groove.

[0015] In the above technical solution, by cooperating with the drive cam and cam bearing, the structure of the drive component can be simplified, and the synchronization between the battery attitude adjustment and the overall movement of the battery carrier can be improved. The attitude adjustment of the battery cell can be completed at the same time as moving to the corresponding work station, which is conducive to improving production efficiency and reducing structural costs.

[0016] According to some embodiments of this application, the drive assembly further includes a reset member, which is disposed between the drive seat and the drive slider, or the reset member is disposed on the power output end.

[0017] In the above technical solution, the attitude adjustment of the battery cell can be automatically reset, thereby enabling reciprocating continuous flipping operation, and can be adapted to the magnetic drive guide rail where the drive seat is located, realizing dynamic processing along the path, which can improve adaptability.

[0018] According to some embodiments of this application, the drive base includes a base plate and an upright plate, the upright plate being disposed on the base plate, and the vehicle body being rotatably disposed at the end of the upright plate away from the base plate to switch between a first position and a second position.

[0019] In the above technical solution, by setting the upright plate, the carrier body can be positioned relatively above the base plate and at a certain distance from the base plate, so that when the carrier body rotates on the upright plate, there will be no motion interference between the carrier body and the base plate, which can improve the rotational stability and reliability of the carrier body and the battery cells set on the carrier body.

[0020] According to some embodiments of this application, there are two upright plates, which are arranged opposite to each other, and the upright plates and the bottom plate surround a receiving cavity, and the driving component is arranged in the receiving cavity.

[0021] In the above technical solution, on the one hand, at least part of the drive component can be set in the accommodating cavity, and at least in the flipping direction of the vehicle body, the drive component can avoid collisions, thereby reducing the probability of motion interference and improving motion stability. On the other hand, the upright plate and the bottom plate can provide structural protection for the drive component, reducing the probability of the drive component being directly impacted by other surrounding components, which is conducive to extending the service life of the battery vehicle.

[0022] According to some embodiments of this application, a slide rail is provided on the base plate, the drive unit is configured as a follower, and the drive unit is slidably disposed on the slide rail.

[0023] In the above technical solution, in the embodiment where the driving part is constructed as a follower such as a driving slider, a slide rail is provided on the base plate. The slide rail slides and the driving part, which can guide the movement of the driving part and limit the movement direction, so that the driving part can move linearly in the expected direction. It can also improve the stability and reliability of the vehicle body in adjusting the attitude of the battery cells.

[0024] According to some embodiments of this application, a support member is provided on the side of the upright plate away from the receiving cavity. The support member protrudes from the top or side of the upright plate and is used to support the carrier body.

[0025] In the above technical solution, when the battery cell is in a flat position, the support component can support the carrier body from below and limit the carrier body to prevent excessive rotation. It can also buffer the impact of the carrier body to reduce the probability of the battery cell moving around, thereby improving the processing accuracy and quality of the battery cell and increasing the processing yield.

[0026] According to some embodiments of this application, a pivot is provided on the upright plate, and the vehicle body is rotatably mounted on the pivot.

[0027] In the above technical solution, a rotating shaft is provided on the upright plate. The rotating shaft is interference-fitted with the power input end, so that the vehicle body can rotate relative to the drive seat, which helps to improve the rotational stability of the vehicle body.

[0028] According to some embodiments of this application, the vehicle body includes: a support plate and a mounting ear. The support plate has a mounting ear on one side, and the mounting ear is rotatably engaged with the vehicle body.

[0029] According to some embodiments of this application, the carrier body further includes: a mounting block located on the side of the support plate away from the mounting ear, wherein there is at least one mounting block, and when there are multiple mounting blocks, the mounting blocks are arranged sequentially in the length direction of the support plate, and the mounting blocks define the battery mounting position.

[0030] In the above technical solution, each mounting block has a battery mounting position, which can be used to install and fix a single battery cell. In embodiments with multiple mounting blocks, the attitude adjustment of multiple battery cells can be realized simultaneously, which is beneficial to further improve production efficiency.

[0031] According to some embodiments of this application, the mounting block is provided with a magnetic fixing part, and a limiting claw is provided on at least one side of the mounting block. The magnetic fixing part is used to magnetically fix the battery cell, and the limiting claw is used to push against at least one end face of the battery cell to limit the battery cell.

[0032] In the above technical solution, the dual limiting structure of magnetic fixing part and limiting claw can be used to achieve adsorption and fixation of battery cells, and the limiting claw can achieve physical limiting and locking. The dual protection can reduce the probability of battery cells shifting, falling or loosening due to vibration and inertia during high-speed transportation, dynamic flipping and continuous movement. It can improve the operation stability of production equipment and help improve the processing yield.

[0033] Secondly, this application provides a production equipment, including: multiple workstations, a magnetic drive rail, and the battery carrier in the above embodiments. Each workstation is equipped with different processing devices. The magnetic drive rail is arranged according to the processing sequence of the multiple workstations. The drive seat of the battery carrier is movably arranged on the magnetic drive rail so that the battery carrier is suitable for sequentially flowing through the multiple workstations.

[0034] According to the production equipment of the embodiments of this application, the battery carrier is movably mounted on the magnetic drive rail. That is, the drive seat of the battery carrier is constructed as a magnetic drive unit, and a guide wheel can be provided at the bottom end. A magnetic drive unit that cooperates with the magnetic drive of the magnetic drive rail can be provided in the middle area. The carrier body is rotatably mounted on the drive seat and moves synchronously with the drive seat and the battery cell. There is no need to set up a battery flipping device with a fixed station. The battery cell is flipped synchronously during the movement of the battery cell. The whole process does not occupy the production cycle of the equipment, which helps to improve production efficiency.

[0035] According to some embodiments of this application, the drive unit of the battery carrier is configured as a follower, the drive unit is a cam bearing, and the production equipment further includes: at least one drive cam, the drive cam is disposed on one side of the magnetic drive guide rail and is disposed corresponding to at least one workstation.

[0036] In the above technical solution, the attitude adjustment of the battery cell is achieved by the cooperation of the drive cam and the cam bearing, which makes the adjustment easier and provides higher synchronization and stability.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0049] In this application, "multiple" means two or more (including two).

[0050] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0051] The battery cell can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0052] For example, a battery cell typically includes a housing, an electrode assembly, and an electrolyte. The housing houses the electrode assembly and the electrolyte. The housing has output terminals, which are typically multiple and include at least one positive output terminal and at least one negative output terminal. The electrode assembly within the housing can be one or more, and is formed by stacking or winding a positive electrode sheet, a negative electrode sheet, and a separator.

[0053] The production equipment in this application embodiment is equipment used in the production process of battery cells. For example, the production equipment may have multiple workstations, and each workstation performs one process in the production process of battery cells.

[0054] The battery carrier in this application embodiment is used to load battery cells and is adapted to drive the battery cells to move between multiple workstations so that the battery cells can be processed by different production devices at different workstations. The battery cells that are finally removed from the production equipment can be semi-finished battery cells that have completed some processing steps or finished battery cells that have completed all processing steps. This application does not make any specific restrictions.

[0055] It should be noted that in the existing technology, whether it is a square battery or a cylindrical battery, the battery cells need to be moved between multiple workstations during the processing. At different workstations, the battery cells may be in different positions to facilitate processing.

[0056] For example, taking cylindrical batteries as an example, in the downstream automated production process of cylindrical batteries, different workstations have different requirements for the placement posture of the battery elevator. Some workstations require the battery cells to be in a flat position to complete the processing, such as inspection and cleaning. Other workstations require the battery cells to be kept in a vertical position for processing (such as liquid injection, sealing, laser welding, and appearance re-inspection). Therefore, it is necessary to set up a matching battery flipping device.

[0057] In the existing technology, the battery flipping device needs to be set up independently downstream of the workstation. That is, a dedicated flipping robot and rotary cylinder flipping module are set up at a fixed workstation of the production equipment. After the battery carrier is transported to this workstation, the equipment stops transporting and completes the flipping and posture correction of the individual battery cells before continuing to transport and process them downstream.

[0058] Therefore, the existing battery flipping device is an independent fixed workstation structure, which requires separate equipment cycle time and factory space. With the development of high-speed and integrated production equipment, the traditional battery flipping device will directly limit the production cycle time of the entire production equipment, causing production bottlenecks and affecting production efficiency. At the same time, the battery flipping device has a complex structure, many parts, and high maintenance costs, which cannot adapt to the new production mode of high-speed conveying and dynamic processing, and it is difficult to meet the current demand for efficient, continuous, and uninterrupted automated production of battery cells.

[0059] In other words, the existing battery flipping device has the following disadvantages and deficiencies: 1. It occupies the production cycle and limits the production efficiency of production equipment.

[0060] The battery flipping device requires a flipping cylinder or a flipping robot. The machine needs to stop flipping, and the delivery of individual battery cells needs to be paused at a fixed workstation. The delivery needs to continue after the flipping action is completed. In high-speed production mode, this will seriously slow down the production cycle and cannot be adapted to high-speed production mode, especially magnetic drive conveyor high-speed production.

[0061] 2. Redundant structure and low integration.

[0062] The battery flipping device is set up independently at one workstation. If the production equipment needs to flip the battery multiple times, multiple battery flipping devices need to be set up, occupying multiple workstations. The frame, drive components, sensors, and control circuits need to be arranged separately. The overall structure is large in size, has many parts, and occupies a lot of factory space. This is not conducive to the miniaturization and integration of the overall production equipment. Furthermore, the assembly, debugging, and subsequent maintenance are difficult and costly.

[0063] 3. Poor operational stability; battery cells are prone to falling off or shifting.

[0064] The battery flipping device uses mechanical buckles or elastic clamping mechanisms. During the high-speed transport and flipping switching of battery cells, the battery cells are prone to loosening, shifting or even falling off due to vibration, inertial force, etc., making it difficult to guarantee the yield rate and lacking a reliable anti-fall limit structure.

[0065] 4. It cannot perform follow-up operations and has poor adaptability.

[0066] The battery flipping device lacks an automatic reset function, cannot return to its initial position after flipping, cannot perform reciprocating continuous flipping operations, and cannot be equipped with a magnetic drive guide rail for dynamic processing, resulting in poor adaptability.

[0067] 5. Poor process compatibility.

[0068] The battery flipping device can only achieve a single unidirectional flip and cannot be compatible with multiple process modes such as flat processing and vertical processing of battery cells at the same time. The process switching requires the use of multiple battery flipping devices, and different flipping devices are difficult to use interchangeably, resulting in poor compatibility.

[0069] Based on this, this application proposes a battery carrier and production equipment. The battery carrier is equipped with a drive base, which can cooperate with a magnetic drive rail and can realize the posture reset of the battery cells through a reset component, so as to achieve follow-up operation and better adaptability. During the movement between multiple workstations, the posture of the battery cells can be automatically adjusted under the action of the drive unit. It can adapt to various process modes and has better process compatibility. There is no need to set up a battery flipping device. The posture adjustment of the battery cells is realized synchronously with the movement, which can reduce the space occupation of the factory. There is no need to stop the machine to flip, which can balance production efficiency. The structure is simple and conducive to improving the integration of production equipment and realizing miniaturization. At the same time, by setting up a limit claw and a magnetic fixing part, the probability of falling or shifting during the posture adjustment of the battery cells can be reduced, which can improve the yield rate.

[0070] The following is for reference. Figures 1-8 This application describes a battery carrier 100 and a production equipment 1000 according to embodiments thereof.

[0071] like Figure 3 and Figure 4 As shown, this application provides a battery carrier 100, including: a drive base 10, a carrier body 20, and a drive assembly 30.

[0072] The drive base 10 is used to drive the carrier body 20 to move between multiple workstations 200. The carrier body 20 is movably mounted on the drive base 10 and is provided with a battery mounting position for fixing a single battery cell. The drive assembly 30 is mounted on the drive base 10 and is poweredly connected to the carrier body 20. It is used to drive the carrier body 20 to switch between at least two positions. The battery cells have different postures above the drive base 10 in different positions of the carrier body 20 to adapt to the posture requirements of the battery cells during the processing of different workstations 200.

[0073] It should be noted that the battery cell in this embodiment can be a square battery or a cylindrical battery, and the carrier body 20 fixes at least one battery cell.

[0074] Specifically, the carrier body 20 can move between multiple workstations 200 under the drive of the drive seat 10. When it moves to the location of different workstations 200, the battery cells located on the battery carrier 100 can be processed by the processing device on the workstation 200. The drive component 30 can drive the carrier body 20 to switch between at least two positions. At different positions, the battery cells have different postures. This allows the carrier body 20 and the battery cells to move synchronously under different workstations 200, so that the battery cells can be switched to the posture that meets the processing requirements.

[0075] It should be noted that switching between at least two positions allows a single battery cell to have at least two postures, such as a vertical posture and a horizontal posture. The vertical posture can be further divided into an inverted posture and an upright posture. Of course, there can also be multiple intermediate postures between the vertical posture and the horizontal posture.

[0076] It is understandable that by driving the carrier body 20 through the drive component 30, the attitude adjustment of the battery cell can be completed. The attitude adjustment of the battery cell does not require a separate battery flipping device, which can simplify the structure of the production equipment 1000 and reduce the space occupied by the production equipment 1000. At the same time, the attitude adjustment of the battery cell can be realized simultaneously while the drive seat 10 drives the carrier body 20 to move. There is no need to stop the machine to adjust the attitude of the battery cell separately, which can reduce the production cycle, improve processing efficiency, and meet the needs of efficient, continuous and uninterrupted automated production of battery cells.

[0077] In other words, there is no need to set up a battery flipping device. On the one hand, it can reduce the occupation of workstation 200. There is no need to arrange and install racks, drive components, sensors, and control lines separately. The overall structure is large in volume, has a large number of parts, and occupies less factory space. This is conducive to the miniaturization and integration of the production equipment 1000 as a whole. It can improve structural redundancy, increase integration, and make assembly, debugging, and subsequent maintenance easier and cheaper. On the other hand, there is no need to stop the battery cell attitude adjustment. The battery carrier 100 can transfer battery cells and adjust battery cell attitude simultaneously, which can be adapted to high-speed production mode.

[0078] According to the battery carrier 100 of the present application embodiment, by setting a drive component 30, the drive component 30 can drive the carrier body 20 to switch between at least two positions, so as to realize the attitude adjustment of the battery cells simultaneously during the process of the battery carrier 100 transporting battery cells, and realize the battery cells to flip along with the movement, so that there is no need to set up a separate battery flipping device. On the one hand, it can improve the structure of the production equipment 1000, increase the integration, and help reduce production costs. On the other hand, it can improve the production efficiency of the production equipment 1000 and adapt to the production cycle requirements of high-speed production mode without stopping the machine to adjust the attitude of the battery cells.

[0079] Combination Figure 3 and Figure 4 As shown, according to some embodiments of this application, the vehicle body 20 is rotatably disposed on the drive seat 10, and the drive assembly 30 is used to drive the vehicle body 20 to rotate relative to the drive seat 10 to switch between at least a first position and a second position. In the first position, the battery cell is in an upright posture, and in the second position, the battery cell is in a lying posture.

[0080] For example, the battery carrier 100 can complete the flat loading, processing, and inspection of battery cells in the second position, and after being flipped to the first position, the vertical processing of battery cells can be completed in the first position.

[0081] In this way, it can be compatible with multiple process modes such as flat processing and vertical processing of battery cells at the same time, without changing tooling or adjusting equipment. It can be compatible with at least two processing modes of flat and vertical battery cells, making the battery carrier 100 more versatile and adaptable to different processes.

[0082] like Figure 6 As shown, according to some embodiments of this application, the drive assembly 30 includes: a drive unit 31, which is configured as a power source and is used to actively drive the vehicle body 20 to rotate relative to the drive seat 10, or the drive unit 31 is configured as a follower and is used to passively drive the vehicle body 20 to rotate relative to the drive seat 10.

[0083] Specifically, in some embodiments, the drive unit 31 can be configured as a power source. The power source can be interconnected with multiple workstations 200 through structures such as controllers and sensors. When moving to different workstations 200, it can switch to the posture of the battery cell corresponding to that workstation 200. In other embodiments, the drive unit 31 can be configured as a follower. It can adjust the posture of the battery cell while moving synchronously with the drive seat 10, which has better synchronization and does not require the setting of controllers, sensors and other structures. This simplifies the structure of the battery carrier 100, improves process compatibility and adaptability of the battery carrier 100.

[0084] In this way, by setting a drive unit 31 that actively drives the carrier body 20 to move, or by setting a drive unit 31 that passively drives the carrier body 20 to move, the carrier body 20 can synchronously drive the seat 10 to adjust the posture of the battery cells, thereby improving process compatibility and adaptability of the battery carrier 100. This allows multiple workstations 200 with different battery cell postures to be integrated on the same production equipment 1000, improving structural redundancy and facilitating the miniaturization and compact design of the production equipment 1000.

[0085] According to some embodiments of this application, the drive assembly 30 further includes a transmission part 32, which is configured as any one of a gear and rack transmission group, a lead screw and nut transmission group, and a crank and slider transmission group. The power output end 322 of the transmission part 32 is connected to the carrier body 20, and the power input end 321 of the transmission part 32 is connected to the drive part 31.

[0086] Specifically, the transmission unit 32 includes a power input end 321 and a power output end 322. The power input end 321 is constructed as a lead screw, the power output end 322 is constructed as a nut, the power input end 321 is constructed as a rack, the power output end 322 is constructed as a gear, the power input end 321 is constructed as a slider, and the power output end 322 is constructed as a crank.

[0087] Furthermore, the drive unit 31 is connected to the power input end 321, and the power output end 322 is connected to the vehicle body 20 to form a complete power transmission path. The drive unit 31 drives the power input end 321 to make linear motion. The power input end 321 and the power output end 322 cooperate (e.g., meshing transmission) to convert linear motion into rotation, so as to drive the vehicle body 20 to flip relative to the drive seat 10, thereby allowing switching between at least the first position and the second position.

[0088] Of course, the drive unit 31 can be configured as a rotating motor, in which case the transmission unit 32 can be used to reduce speed and increase torque to improve the smoothness of the tilting motion of the vehicle body 20.

[0089] Thus, by setting the transmission unit 32, in the embodiment where the drive unit 31 is configured as a power source, the smoothness of the vehicle body 20 switching between multiple positions can be improved. In the embodiment where the drive unit 31 is configured as a follower, it can be adapted to the movement of the drive seat 10, and the synchronization and reliability of the following posture adjustment can also be improved.

[0090] Combination Figure 1 , Figure 2 and Figure 3 As shown, according to some embodiments of this application, the drive unit 31 is configured as a follower and is constructed as a drive slider. The drive slider is connected to the power input end 321 and is slidably connected to the drive seat 10. One end of the drive slider is provided with a cam bearing 311. A drive cam 400 is provided on the station 200 where the battery cell attitude needs to be changed. The drive cam 400 has a cam groove 410, and the cam bearing 311 is disposed in the cam groove 410 so as to drive the carrier body 20 to rotate according to the motion trajectory of the cam bearing 311 defined by the cam groove 410.

[0091] Specifically, the drive cam 400 is provided with a cam groove 410, and the cam groove 410 is provided with a motion trajectory with peaks and troughs. The cam bearing 311 at the end of the drive unit 31 can move into the cam groove 410 and can push the drive slider to make linear motion according to the trajectory of peaks and troughs. The transmission unit 32 can be constructed as a gear and rack assembly, with the rack connected to the drive slider and the gear connected to the carrier body 20. When the battery carrier 100 moves to the corresponding work station 200 where the battery cell posture needs to be adjusted, the posture adjustment of the battery cell is realized by the cooperation of the drive cam 400 and the cam bearing 311.

[0092] In this way, by cooperating with the cam bearing 311, the structure of the drive assembly 30 can be simplified, and the synchronization between the battery attitude adjustment and the overall movement of the battery carrier 100 can be improved. The attitude adjustment of the battery cell can be completed at the same time as moving to the corresponding workstation 200, which is conducive to improving production efficiency and reducing structural costs.

[0093] like Figure 6 and Figure 7 As shown, according to some embodiments of this application, the drive assembly 30 further includes a reset member 33, which is disposed between the drive seat 10 and the drive slider, or the reset member 33 is disposed on the power output end 322.

[0094] In some embodiments, the reset member 33 is constructed as a linear spring and disposed between the carrier body 20 and the drive slider; in other embodiments, the reset member 33 is constructed as a torsion spring and disposed on the power output end 322.

[0095] When the cam bearing 311 moves out of the cam groove 410, the cam bearing 311 disengages from the trajectory limit of the cam groove 410, and the elastic potential energy of the reset member 33 automatically pushes the transmission component and the carrier body 20 to reset, so that the carrier body 20 can be reset to the initial state. If the first position is the initial state, it is reset to the first position; if the second position is the initial state, it is reset to the second position. This can realize continuous reciprocating and automatic cyclic flipping operation.

[0096] In this way, the attitude adjustment of the battery cell can be automatically reset, thereby enabling reciprocating continuous flipping operations. It can also be adapted to the magnetic drive guide rail 300 where the drive seat 10 is located, enabling dynamic processing along the path and improving adaptability.

[0097] like Figure 4 and Figure 7 As shown, according to some embodiments of this application, the drive seat 10 includes a base plate 12 and an upright plate 11. The upright plate 11 is disposed on the base plate 12, and the carrier body 20 is rotatably disposed at the end of the upright plate 11 away from the base plate 12 to switch between a first position and a second position.

[0098] Specifically, the upright plate 11 is mounted on the base plate 12 and can extend away from the base plate 12, and the vehicle body 20 is rotatably mounted at the end of the upright plate 11 away from the base plate 12.

[0099] In this way, by setting the upright plate 11, the vehicle body 20 can be positioned above the base plate 12 and at a certain distance from the base plate 12, so that when the vehicle body 20 rotates on the upright plate 11, there will be no motion interference between the vehicle body 20 and the base plate 12, which can improve the rotational stability and reliability of the vehicle body 20 and the battery cells set on the vehicle body 20.

[0100] Combination Figure 4 and Figure 7 As shown, according to some embodiments of this application, there are two upright plates 11, which are arranged opposite to each other, and the upright plates 11 and the bottom plate 12 surround a receiving cavity, and the driving assembly 30 is disposed in the receiving cavity.

[0101] Specifically, the power output end 322 of the transmission unit 32 is disposed in the accommodating cavity, and at least a portion of the power input end 321 and the drive unit 31 is disposed in the accommodating cavity.

[0102] In this way, on the one hand, at least part of the drive assembly 30 can be placed in the accommodating cavity, and at least in the flipping direction of the vehicle body 20, the drive assembly 30 can avoid collisions, thereby reducing the probability of motion interference and improving motion stability. On the other hand, the upright plate 11 and the bottom plate 12 can provide structural protection for the drive assembly 30, reducing the probability that the drive assembly 30 will be directly impacted by other surrounding components, which is conducive to extending the service life of the battery vehicle 100.

[0103] Combination Figure 5 and Figure 6 As shown, according to some embodiments of this application, a slide rail 13 is provided on the base plate 12, the drive unit 31 is configured as a follower, and the drive unit 31 is slidably disposed on the slide rail 13.

[0104] Specifically, in embodiments where the drive unit 31 is configured as a follower such as a drive slider, a slide rail 13 is provided on the base plate 12. The slide rail 13 slides in cooperation with the drive unit, which can guide the movement of the drive unit 31 and limit its movement direction, so that the drive unit 31 can move linearly in the expected direction. It can also improve the stability and reliability of the vehicle body 20 in adjusting the attitude of the battery cells.

[0105] like Figure 7 As shown, according to some embodiments of this application, a support member 14 is provided on the side of the upright plate 11 away from the accommodating cavity. The support member 14 protrudes from the top or side surface of the upright plate 11 and is used to support the carrier body 20.

[0106] Specifically, the support member 14 may include a connecting plate 141 and a first support plate 142 at the top of the connecting plate 141. The connecting plate 141 is connected to the upright plate 11. The first support plate 142 extends away from the upright plate 11 relative to the connecting plate 141. A second support plate 143 is provided laterally on the connecting plate 141. The first support plate 142 and the second support plate 143 are respectively adapted to support and limit the vehicle body 20 when the vehicle body 20 is in the second position and the first position.

[0107] In this way, when the battery cell is in a flat position, the support member 14 can support the carrier body 20 from below and limit the carrier body 20, preventing the carrier body 20 from rotating excessively and buffering the impact of the carrier body 20, thereby reducing the probability of the battery cell moving around, which helps to improve the processing accuracy and quality of the battery cell and increase the processing yield.

[0108] According to some embodiments of this application, a pivot 15 is provided on the upright plate 11, and the carrier body 20 is rotatably disposed on the pivot 15.

[0109] Specifically, a rotating shaft 15 is provided on the upright plate 11. The rotating shaft 15 is interference-fitted with the power input end 321, so that the vehicle body 20 can rotate relative to the drive seat 10, which helps to improve the rotational stability of the vehicle body 20.

[0110] In one embodiment where the elastic element is a torsion spring, the torsion spring is disposed on the power output end 322, and one torsion arm of the torsion spring pushes against the power output end 322. One torsion arm can be fixed on the rotating shaft 15 to realize elastic energy storage and reset after the release of elastic potential energy.

[0111] like Figure 4 As shown, according to some embodiments of this application, the vehicle body 20 includes: a support plate 21 and a mounting ear 22. The support plate 21 is provided with a mounting ear 22 on one side, and the mounting ear 22 is rotatably engaged with the vehicle body 20.

[0112] The mounting ear 22 is inserted through the rotating shaft 15, and a rotating bearing can also be provided between the mounting ear 22 and the rotating shaft 15 so that the bearing plate 21 can rotate relative to the rotating shaft 15.

[0113] Further integration Figure 4 and Figure 8 As shown, according to some embodiments of this application, the carrier body 20 further includes: a mounting block 23 located on the side of the support plate 21 away from the mounting ear 22. There is at least one mounting block 23. When there are multiple mounting blocks 23, the mounting blocks 23 are arranged sequentially in the length direction of the support plate 21, and the mounting blocks 23 are suitable for fixing the battery cells.

[0114] Specifically, each mounting block 23 has a battery mounting position, which can be used to install and fix a single battery cell. In embodiments with multiple mounting blocks 23, the attitude adjustment of multiple battery cells can be realized simultaneously, which helps to further improve production efficiency.

[0115] Understandably, existing battery flipping devices require stop-and-go flipping through cylinder flipping, robotic arm flipping, and other technical solutions. Material conveying must be paused at fixed station 200 and can only continue after the flipping action is completed. Each battery cell flipping will occupy a fixed amount of time, which will create a serious cycle time bottleneck in high-speed production lines and cannot be adapted to the production mode of continuous high-speed movement of magnetic drive guide rail 300.

[0116] In this application, by setting multiple mounting blocks 23, multiple battery cells can be synchronously flipped, and the drive seat 10 can be adapted to the magnetic drive rail 300 for continuous high-speed operation, thereby improving the overall production efficiency of battery cells.

[0117] like Figure 8 As shown, according to some embodiments of this application, the mounting block 23 is provided with a magnetic fixing part, and a limiting claw 231 is provided on at least one side of the mounting block 23. The magnetic fixing part is used to magnetically fix the battery cell, and the limiting claw 231 is used to push against at least one end face of the battery cell to limit the battery cell.

[0118] It should be noted that in existing technologies, issues such as loosening, shifting, or even falling off of individual battery cells due to vibration and inertial forces make it difficult to guarantee the yield rate, and there is a lack of reliable anti-fall limiting structures.

[0119] In this application, by setting a magnetic fixing part and a limiting claw 231, the limiting claw 231 can be set in pairs, or in three, four, etc. The mounting block 23 defines a battery mounting position with limiting grooves at both ends, and the mounting block 23 is further provided with at least one magnetic fixing part 232.

[0120] In this way, the magnetic fixing part 232 and the limiting claw 231 can achieve adsorption and fixation of the battery cell through the dual limiting structure. The magnetic fixing part 232 can achieve physical limiting and locking. The dual protection can reduce the probability of the battery cell shifting, falling, or loosening due to vibration and inertia during high-speed transportation, dynamic flipping, and continuous travel. This can improve the operational stability of the production equipment 1000 and help improve the processing yield.

[0121] like Figure 1As shown, this application provides a production equipment 1000, including: multiple workstations 200, a magnetic drive rail 300, and a battery carrier 100 as described in the above embodiment. Each workstation 200 is provided with different processing devices. The magnetic drive rail 300 is arranged according to the processing sequence of the multiple workstations 200. The drive seat 10 of the battery carrier 100 is movably arranged on the magnetic drive rail 300 so that the battery carrier 100 is suitable for sequentially flowing through the multiple workstations 200.

[0122] According to the production equipment 1000 of this application embodiment, the battery carrier 100 is movably mounted on the magnetic drive rail 300. That is, the drive seat 10 of the battery carrier 100 is constructed as a magnetic drive, and a guide wheel 121 can be provided at the bottom end. A magnetic drive that cooperates with the magnetic drive of the magnetic drive rail 300 can be provided in the middle area. The carrier body 20 is rotatably mounted on the drive seat 10 and moves synchronously with the drive seat 10 and the battery cells. There is no need to set up a battery flipping device with a fixed station 200. The battery cells are flipped synchronously during the movement of the battery cells. The whole process does not occupy the production cycle of the equipment, which helps to improve production efficiency.

[0123] like Figure 2 As shown, according to some embodiments of this application, the drive unit 31 of the battery carrier 100 is configured as a follower, the drive unit 31 is a cam bearing 311, and the production equipment 1000 further includes: at least one drive cam 400, the drive cam 400 is disposed on one side of the magnetic drive rail 300 and is disposed corresponding to at least one workstation 200.

[0124] Specifically, one of the first position and the second position is the normal position, and the carrier body 20 is usually in the normal position. The station 200 where the attitude of the battery cell needs to be adjusted is further provided with a drive cam 400, so that the attitude of the battery cell is adjusted simultaneously when the battery carrier 100 moves to the station 200.

[0125] It is understandable that by cooperating with the drive cam 400 and the cam bearing 311, the attitude adjustment of the battery cell can be achieved, which is easier to adjust and has higher synchronization and stability.

[0126] The structure of the battery carrier 100 and the production equipment 1000 according to a specific embodiment of this application will be described in detail below.

[0127] Among them, the drive base 10 is an integral sheet metal or machined one-piece molded part. The drive base 10 has reserved standard mounting holes, which can be used to integrate magnetic drive units and realize the rigid locking and fixing of magnetic drive units, ensuring the overall follow-up synchronization of the battery carrier 100 without relative displacement. On the other hand, it provides an installation benchmark for all moving parts such as cam bearing 311, rack, guide rail, reset part 33, rotating shaft 15, and carrier body 20, ensuring the assembly accuracy and coaxiality and parallelism of the transmission components and carrier body 20. It is the basis for the bearing and positioning of the entire battery carrier 100.

[0128] The transmission unit 32 includes a rack and a gear. The drive unit 31 is constructed as a drive slider, which is connected to the rack. The drive slider is slidably mounted on the drive seat 10 via a slide rail 13 and can slide back and forth in the horizontal direction. A cam bearing 311 is fixedly mounted at the end of the drive slider. The wheel structure of the cam bearing 311 is matched with the trajectory curve defined by the cam groove 410 of the drive cam 400 located on one side of the magnetic drive guide rail 300. A reset member 33 is mounted on the side of the drive slider. One end of the reset member 33 abuts against the drive slider, and the other end abuts against the limiting step on the drive seat 10. Under normal conditions, the reset member 33 is in a slightly compressed state to prevent it from falling off. When the reset member 33 is compressed, it can provide a reset preload force for the rack.

[0129] When the magnetic actuator carries the battery carrier 100 forward, the cam bearing 311 contacts the cam groove 410. Under the limiting and guiding action of the trajectory curve defined by the cam groove 410, the cam bearing 311 and the drive slider move linearly along the slide rail 13, providing mechanical power for the subsequent flipping action. When the battery carrier 100 leaves the area covered by the trajectory curve, the limiting action disappears, the reset member 33 releases the elastic force, and pushes the drive slider back to the initial position, completing the mechanical reset.

[0130] The gear and rack mesh with each other, and the shaft 15 is interference-fitted at the center of the gear. The shaft 15 is rotatably mounted on the vertical plate 11 through a bearing seat and can rotate freely. The linear reciprocating motion of the rack can be converted into the rotational motion of the gear and shaft 15 through the gear-rack meshing transmission, realizing the smooth and precise transmission of power. The transmission clearance is small and the flip angle is precise, which can stably realize the attitude switching of the battery cell.

[0131] The end of the rotating shaft 15 is rigidly connected to the fixed carrier body 20. The mounting block 23 of the carrier body 20 can be a cylindrical battery-shaped clamping structure. The mounting block 23 has a fixed permanent magnet (magnetic fixing part 232) embedded inside, and a limiting claw 231 is integrally machined. The magnetic fixing part 232 can generate a continuous attraction force on the cylindrical battery placed in the mounting block 23 to achieve flexible fixation; the limiting claw 231 is stuck on the outer ring of the end face of the battery cell to achieve physical rigid limitation.

[0132] Therefore, a purely mechanical linkage structure is adopted, which involves the drive cam 400, cam bearing 311, drive slider, slide rail 13, rack, and gear. No additional power source such as motor or cylinder is required. The displacement power of the magnetic drive unit is used to constrain the movement of the cam bearing 311 through the cam trajectory, drive the rack to move linearly, and then drive the gear and rotating shaft 15 to rotate, automatically completing the attitude adjustment of the battery cell. The structure is simple, the response is synchronous, no electronic control trigger is required, the cost is low, and the reliability is high.

[0133] Initial state: The magnetic actuator is in the loading station 200, and the carrier body 20 is kept in a flat position under the reset action of the reset component 33. The cylindrical battery is placed on the carrier body 20 by manual or robotic arm. During the following flipping stage: The magnetic actuator carries the battery carrier 100 and the battery cell forward. The cam bearing 311 gradually enters the cam groove 410. Constrained by the cam trajectory, it pushes the rack to slide, drives the gear to rotate, and drives the rotating shaft 15 and the carrier body 20 to rotate synchronously to the first position. The battery cell dynamically flips from a flat position to a vertical position. The entire flipping process is completed during the movement of the battery cell, without stopping the machine or occupying the production cycle. Vertical processing stage: The battery cells remain vertical and move with the magnetic actuator through the corresponding vertical processing station 200 to complete vertical processes such as laser welding, liquid injection, and inspection. Automatic reset stage: The magnetic drive continues to move, the cam bearing 311 disengages from the cam trajectory limit range, the rack automatically resets under the action of the reset component 33, drives the gear to rotate in the opposite direction, the carrier body 20 resets to the second position, and can directly enter the flat processing process or perform secondary loading to complete one complete work cycle.

[0134] In summary, the battery carrier 100 and manufacturing equipment 1000 according to the embodiments of this application.

[0135] 1. It can eliminate cycle time waste and greatly improve production efficiency. The flipping action and the battery cell conveying action are synchronized, without stopping or waiting, with zero cycle time occupation. It is fully compatible with the high-speed continuous production characteristics of the magnetic drive guide rail 300, and the production efficiency is increased by more than 20%.

[0136] 2. A drive cam 400 can be used in conjunction with a cam bearing 311 to achieve a pure mechanical transmission without power, reducing equipment costs and failure rates. The 31 electrical drive components such as cylinders, servo motors, and sensor triggers can be eliminated, and the flipping action can be achieved by mechanical trajectory linkage. The number of parts is greatly reduced, the structure is simple, and there is no need for complex electrical control program matching, which significantly reduces the equipment failure rate and reduces procurement, wiring, debugging, and maintenance costs.

[0137] 3. The reset component 33 realizes automatic cyclic reset, enabling continuous automated mass production. The reset component 33 realizes the automatic restoration of the posture of the carrier body 20. The equipment can continuously and repeatedly perform the full cycle of battery cell feeding - following flip - vertical processing - automatic reset - flat processing or secondary feeding, meeting the needs of uninterrupted automated production line and adapting to large-volume, high-frequency mass production scenarios.

[0138] 4. The dual protection structure improves production yield and stability, effectively counteracts the inertial force and vibration interference generated by high-speed movement and flipping start-stop, reduces the probability of battery cells falling, shifting, or tilting, and provides higher clamping stability for battery cells, which can reduce the process defect rate and the probability of equipment jamming and shutdown.

[0139] 5. Multi-process compatibility and better equipment versatility: A single set of production equipment of 1000 can meet the two mainstream processing techniques of flat and vertical battery cells. It can flexibly adapt to the production needs of different processes before and after, without the need to change tooling or modify equipment, shortening the changeover time and improving the equipment reuse rate.

[0140] Other configurations and operations of the production equipment 1000 according to the embodiments of this application are known to those skilled in the art and will not be described in detail here.
