Description

Technical Field

[0001] This application relates to the field of battery production technology, specifically to a battery module shaping and pressurizing equipment and a battery production line. Background Technology

[0002] In the production process of power battery modules, battery modules are made up of multiple cells stacked together. After the cells are stacked and arranged, defects such as uneven distribution of gaps between individual cells, out-of-tolerance overall dimensions of the module, and loose cell stacking structure are prone to occur, which directly affect the subsequent assembly accuracy and battery pack safety performance.

[0003] To address molding defects after cell stacking, the industry currently employs a shaping and pressurizing process to correct and shape the stacked cell modules. During this process, the modules to be shaped are placed inside a dedicated module carrier, and external pressure is applied to the modules to eliminate gap deviations between cells and to standardize the overall shape of the module. However, during the shaping and pressurizing process, the module carrier is prone to shifting, resulting in uneven distribution of the shaping pressure applied to the modules and affecting the structural stability of the modules.

[0031] The following is combined Figures 1 to 10 This application describes a battery module shaping and pressurizing equipment and a battery production line according to embodiments of the present application.

[0032] According to embodiments of this application, in a first aspect, a battery module shaping and pressurizing device is provided, such as... Figure 1 As shown, the battery module shaping and pressurizing equipment includes a frame 1, a module carrier 2, a carrier locking mechanism 3, and a module shaping mechanism 4. Specifically, the frame 1, as the main support of the equipment, can be welded from steel, forming a rigid frame structure to ensure overall stability and structural resistance to deformation during operation. The frame 1 has a module placement station 101. Optionally, a hollowed-out area is reserved in the middle of the frame 1 to form the module placement station 101. Sufficient operating space is left around the module placement station 101 to accommodate the placement of power battery modules. It should be noted that in this embodiment, the battery module shaping and pressurizing equipment has a first direction X, a second direction Y, and a third direction Z that intersect perpendicularly. Specifically, as shown... Figure 1 As shown, the first direction X is the length direction of the rack 1, the second direction Y is the width direction of the rack 1, and the third direction Z is the height direction of the rack 1. The module carrier 2 is disposed at the module placement station 101, and the module carrier 2 is used to receive and transport battery modules. Optionally, as... Figure 1 As shown, the module carrier 2 can enter and exit the module placement station 101 along the first direction X via a double-speed chain drive, realizing the battery module loading, transfer, shaping and unloading operations.

[0033] like Figure 2As shown, the module carrier 2 includes a support platform 201 and a module positioning mechanism 202 disposed on the support platform 201. The support platform 201 has a bearing portion 2011 for receiving battery modules, and the module positioning mechanism 202 is used to position and clamp the battery modules. Optionally, the main body of the module carrier 2 is a steel structure, and the support platform 201 has multiple sets of parallel protruding strips forming the bearing portion 2011. Anti-slip buffer pads can be attached to the surface of the bearing portion 2011 to avoid direct hard contact between the battery module shell and the metal, which could cause scratches or bumps, and to increase friction to prevent the module from slipping. During loading, a person or a robot places the battery module to be shaped on the bearing portion 2011, and the module positioning mechanism 202 completes the limiting clamping, limiting the degree of freedom of the battery module in the XY plane, and ensuring that the placement position of each batch of battery modules on the support platform 201 is uniform.

[0034] like Figure 1 As shown, the carrier locking mechanism 3 is mounted on the frame 1. The carrier locking mechanism 3 is used to lock the module carrier 2 onto the frame 1, or to release the locking constraint between the module carrier 2 and the frame 1. The module shaping mechanism 4 is mounted on the frame 1, and is located above the module placement station 101 along the third direction Z. The module shaping mechanism 4 is used to pressurize and shape the battery module. When the module carrier 2, carrying the battery module, is fully slid into the module placement station 101, the carrier locking mechanism 3 locks the module carrier 2 inside the station of the frame 1, restricting all degrees of freedom of the support platform 201, ensuring that the module carrier 2 and the frame 1 remain relatively stationary. Subsequently, the module shaping mechanism 4 operates to perform pressurization and shaping operations on the battery module. After all the shaping processes are completed, the control system outputs an unlocking signal to the carrier locking mechanism 3 to release the locking constraint between the module carrier 2 and the frame 1. The module carrier 2 can then move relative to the frame 1. At this time, the module carrier 2 can smoothly slide out of the workstation to complete the unloading and transfer.

[0035] With this setup, during operation, the battery module to be shaped is placed on the module carrier 2, and the module positioning mechanism 202 completes the module positioning and clamping. After the module carrier 2 is transported to the module placement station 101 of the frame 1, the carrier locking mechanism 3 locks the module carrier 2 to the frame 1. Then, the module shaping mechanism 4 applies pressure to shape the battery module. This equipment can stably lock the module carrier 2 during the shaping and pressurizing process, effectively preventing displacement of the module carrier 2, ensuring uniform application of shaping pressure, and effectively improving the overall structural stability of the battery module after shaping.

[0036] Optionally, in some embodiments of this application, such as Figure 2 and Figure 3As shown, the carrier locking mechanism 3 includes a first locking member 301, a second locking member 302, and a locking drive member 303. The first locking member 301 is disposed on the module carrier 2, and the second locking member 302 is adapted to the first locking member 301 and is movably disposed on the frame 1. The second locking member 302 is configured to lock the module carrier 2 onto the frame 1 when it moves to connect with the first locking member 301, and to release the locking constraint between the module carrier 2 and the frame 1 when it moves to separate from the first locking member 301. The locking drive member 303 is connected to the second locking member 302 and is used to drive the second locking member 302 to move to connect with or separate from the first locking member 301.

[0037] It is understood that the second locking member 302 has a first position and a second position, and the locking drive member 303 can drive the second locking member 302 to switch between the first position and the second position. When the second locking member 302 is in the first position, the second locking member 302 is connected to the first locking member 301 to lock the module carrier 2 on the frame 1, restricting all displacement degrees of freedom of the module carrier 2. When the second locking member 302 is in the second position, the second locking member 302 is separated from the first locking member 301 to release the locking constraint between the module carrier 2 and the frame 1, release the module carrier 2, and the module carrier 2 can smoothly slide out of the workstation.

[0038] Optionally, the first locking member 301 and the second locking member 302 are connected by a snap-fit ​​connection. For example, the first locking member 301 is provided with a snap-fit, and the second locking member 302 is provided with a matching buckle. The locking drive member 303 drives the second locking member 302 to move to the snap-fit ​​position with the first locking member 301, thereby locking the module carrier 2 and the frame 1; the locking drive member 303 drives the second locking member 302 to the disengagement position from the first locking member 301, thereby releasing the module carrier 2. In other embodiments, the first locking member 301 and the second locking member 302 adopt a pin structure. For example, the first locking member 301 has a locking hole, and the second locking member 302 is a locking pin, with the mating end of the locking pin matching the locking hole of the first locking member 301. The locking drive 303 drives the second locking member 302 to extend toward the first locking member 301 and insert into the locking hole, thereby locking the module carrier 2 and the frame 1. The locking drive 303 also drives the second locking member 302 to retract away from the first locking member 301, releasing the locking constraint between the module carrier 2 and the frame 1. The locking drive 303 can be a cylinder, an electric telescopic rod, a servo motor with a ball screw drive structure, etc.

[0039] This configuration, employing a paired plug-in locking mechanism between the first locking component 301 and the second locking component 302, enables multi-directional displacement constraint on the module carrier 2, reliably locking the module carrier 2. Simultaneously, a driving component drives the second locking component 302 to perform reciprocating motion, achieving automatic switching between locking and releasing without the need for manual assistance. This configuration is suitable for continuous operation on automated production lines, effectively improving production efficiency.

[0040] Optionally, in some embodiments of this application, such as Figure 3 As shown, the battery module shaping and pressurizing equipment also has a first direction X and a second direction Y. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The second locking member 302 is movably mounted on the frame 1 along the first direction X. The carrier locking mechanism 3 also includes a first moving component 304 and a second moving component 305. The first moving component 304 is connected to the locking drive member 303 and is used to drive the locking drive member 303 to move along the third direction Z. The second moving component 305 is connected to the first moving component 304 and is used to drive the first moving component 304 to move along the second direction Y.

[0041] In this embodiment, as Figure 3 As shown, the first moving component 304 is assembled at the motion output end of the second moving component 305. The locking drive component 303 is integrally mounted and fixed on the first moving component 304. The first moving component 304 can drive the locking drive component 303 and the second locking component 302 to synchronously adjust their vertical displacement along the third direction Z. The second moving component 305 is fixedly mounted on the side bracket of the frame 1. The motion output end of the second moving component 305 carries the first moving component 304. The second moving component 305 can drive the first moving component 304, the locking drive component 303, and the second locking component 302 to perform lateral displacement adjustment as a whole along the second direction Y.

[0042] This configuration allows for lateral adjustment in the second direction (Y) via the second moving component 305 and lateral adjustment in the third direction (Z) via the first moving component 304. This enables overall adjustment of the spatial coordinates of the second locking element 302, ensuring it aligns with the first locking element 301 on different vehicles. This eliminates the need to replace the entire vehicle locking mechanism 3; simply adjusting the position of the moving components allows compatibility with various modular vehicle models 2, reducing the need for replacement parts, lowering equipment modification costs, and improving equipment versatility. Simultaneously, it improves mating performance, corrects alignment, and ensures smooth connection between the second locking element 302 and the first locking element 301 along the first direction (X). This eliminates locking failures and jamming caused by manufacturing and assembly errors, reduces the precision requirements for component processing, and facilitates equipment assembly and debugging.

[0043] Optionally, in some embodiments of this application, such as Figure 3 and Figure 4 As shown, the first moving component 304 includes a first fixing member 3041, a transmission component 3042, and a first driving member 3043. The first fixing member 3041 is connected to the second moving component 305, which drives the first fixing member 3041 to move along the second direction Y. The first fixing member 3041 serves as the mounting base of the first moving component 304 and is fixed to the motion output end of the second moving component 305. When the second moving component 305 is working, it directly drives the first fixing member 3041 to move laterally along the second direction Y, thereby achieving position adjustment of the first moving component 304 in the second direction Y.

[0044] Along the third direction Z, the transmission component 3042 is slidably connected to the first fixing member 3041, and the locking drive member 303 is disposed at the end of the transmission component 3042 away from the first fixing member 3041. In this embodiment, the first fixing member 3041 is a rigid connecting plate, and the transmission component 3042 can slide smoothly up and down relative to the first fixing member 3041 along the third direction Z. The locking drive member 303 can be locked and fixed to the outer end of the transmission component 3042 away from the first fixing member 3041 by bolts, and the locking drive member 303 synchronously completes the vertical movement along the third direction Z with the transmission component 3042.

[0045] The first driving member 3043 is disposed on the first fixed member 3041 and is connected to the transmission member 3042. The first driving member 3043 is used to drive the transmission member 3042 to move along the third direction Z, thereby driving the locking driving member 303 to move along the third direction Z. Optionally, the first driving member 3043 may be a cylinder, an electric telescopic rod, etc. The first driving member 3043 receives a command from the control system and outputs power to drive the transmission member 3042 to move up and down relative to the first fixed member 3041 along the third direction Z, thereby driving the locking driving member 303 and the second locking member 302 installed at the end of the transmission member 3042 to jointly achieve the position adjustment in the third direction Z.

[0046] Furthermore, such as Figure 3 As shown, the first fixing member 3041 is provided with a linear bearing 3044 adapted to the transmission member 3042. Along the third direction Z, the transmission member 3042 and the linear bearing 3044 are slidably engaged, which can limit and guide the sliding trajectory of the transmission member 3042 along the third direction Z. The end of the transmission member 3042 is also provided with a limiting block 3045, which can physically limit the movement stroke of the transmission member 3042 along the third direction Z and prevent the transmission member 3042 from slipping out of its travel range.

[0047] With this configuration, the first fixing component 3041 serves as the load-bearing base, enabling overall movement in the second direction Y. The transmission component 3042 slides relative to the third direction Z, completing the position adjustment in both the Y and Z directions. The two sets of directional movements are decoupled, resulting in a shorter transmission path and better overall rigidity. This design can compensate for assembly errors, is compatible with various module carriers 2, and also offers good maintainability. It can withstand the large reaction force impact conditions at the battery module shaping station, ensuring reliable alignment and locking between the second locking component 302 and the first locking component 301.

[0048] Optionally, in some embodiments of this application, such as Figure 3 As shown, the transmission component 3042 includes at least two sliding members 30421 and a second fixing member 30422. Each sliding member 30421 is circumferentially spaced around the first driving member 3043, and each sliding member 30421 extends along a third direction Z. One end of each sliding member 30421 is slidably connected to the first fixing member 3041, and the other end of each sliding member 30421 is fixedly connected to the second fixing member 30422. The locking driving member 303 is disposed on the second fixing member 30422.

[0049] In this embodiment, as Figure 3 As shown, each sliding member 30421 is arranged symmetrically at left and right intervals around the first driving member 3043 in the circumferential direction, and the sliding member 30421 extends vertically along the third direction Z. The sliding member 30421 and the first fixed member 3041 are slidably engaged by a linear bearing 3044, and the sliding member 30421 can reciprocate up and down relative to the first fixed member 3041 along the third direction Z.

[0050] The second fixing member 30422 is a rigid connecting plate, located at the lower end of the sliding member 30421 away from the first fixing member 3041. The lower ends of each sliding member 30421 are bolted to the second fixing member 30422, forming an integral frame structure. The locking drive member 303 is bolted to the plate surface of the second fixing member 30422 facing away from the sliding member 30421. The locking drive member 303, along with the second fixing member 30422 and the sliding member 30421, achieves vertical displacement along the third direction Z. The housing of the first drive member 3043 is fixed to the first fixing member 3041, and the motion output end of the first drive member 3043 is connected downwards along the third direction Z to the middle position of the second fixing member 30422.

[0051] During operation, the second moving component 305 drives the first fixed component 3041 to complete the overall displacement in the second direction Y; the first driving component 3043 drives the second fixed component 30422, and the sliding components 30421 arranged at intervals on both sides provide motion guidance and lateral constraints, realizing the Z-direction lifting and lowering of the locking driving component 303 and the second locking component 302, and completing the alignment in the Y and Z directions. After the alignment is completed, the locking driving component 303 drives the second locking component 302 to extend along the first direction X, and engages with the first locking component 301 of the module carrier 2 to lock.

[0052] This configuration, employing multiple sliding members 30421 to form multi-point guiding constraints, effectively prevents the second fixed member 30422 from shifting or tilting, improving motion stability, reducing the risk of axis misalignment, and minimizing the risk of jamming when the second locking member 302 and the first locking member 301 are engaged, thus ensuring the coaxial alignment accuracy of the locking pair. Multi-point load distribution reduces local stress on individual sliding members 30421, enhancing the overall transmission component 3042's ability to withstand shaping impacts, adapting to the heavy-load impact conditions of the battery module shaping station, and extending equipment lifespan. The overall structure is compact, reducing the mechanism's external dimensions and saving installation space on the frame 1.

[0053] Optionally, in some embodiments of this application, such as Figure 4 As shown, the second moving component 305 includes a third fixing member 3051 and a second driving member 3052. The third fixing member 3051 is connected to the first moving component 304, and the second driving member 3052 is disposed on the frame 1. The second driving member 3052 is also connected to the third fixing member 3051, and is used to drive the third fixing member 3051 to move along the second direction Y, thereby causing the first moving component 304 to move along the second direction Y.

[0054] In this embodiment, as Figure 4 As shown, the second driving component 3052 can be a cylinder, an electric telescopic rod, etc. The second driving component 3052 is fixedly mounted on the side support of the frame 1. The second driving component 3052 is arranged along the second direction Y, and its motion output end is fixedly connected to the third fixed component 3051. Simultaneously, the first fixed component 3041 of the first moving component 304 is bolted to the third fixed component 3051. When the third fixed component 3051 moves, it directly drives the first moving component 304 to move synchronously. The frame 1 is also equipped with a first linear guide rail pair 306 extending along the second direction Y. The guide rail base is locked and fixed to the frame 1, and the sliding seat of the guide rail pair is rigidly connected to the bottom of the first fixed component 3041, providing guiding constraints for the Y-axis movement of the third fixed component 3051 and the first moving component 304, ensuring smooth operation during the movement process.

[0055] During operation, once the module carrier 2 slides into the module placement station 101 and is in place, the control system, based on the actual coordinates of the first locking member 301, controls the second driving member 3052 to drive the third fixing member 3051 to move along the second direction Y, completing the Y-axis alignment. Subsequently, the first moving component 304 completes the third direction Z-axis height alignment, aligning the second locking member 302 with the axis of the first locking member 301. After alignment, the locking driving member 303 drives the second locking member 302 to extend and engage along the first direction X, achieving locking and fixing of the module carrier 2 to the frame 1. After the shaping process is completed, the second locking member 302 retracts and unlocks, allowing the module carrier 2 to slide out of the station for unloading.

[0056] With this configuration, the second driving component 3052 drives the third fixed component 3051, which in turn drives the first moving component 304 to achieve overall Y-axis translational adjustment. The driving source is fixed on the frame 1, reducing the motion load and lowering cable maintenance costs. The Y-axis and Z-axis movements are decoupled, simplifying alignment control, compensating for assembly errors, and being compatible with various carrier specifications. It can withstand lateral impact loads under shaping conditions, ensuring the alignment accuracy of the locking pair, and also has the advantages of modular assembly and easy maintenance.

[0057] Optionally, in some embodiments of this application, such as Figure 2 As shown, the battery module shaping and pressurizing equipment also has a first direction X and a second direction Y. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The module positioning mechanism 202 includes a pair of opposing first stops 2021 and a pair of opposing second stops 2022. The pair of first stops 2021 are respectively disposed on both sides of the bearing portion 2011 along the second direction Y. At least one of the pair of first stops 2021 is slidably connected to the support platform 201. The pair of first stops 2021 can move closer or further apart along the second direction Y to clamp or release the battery module. It can be understood that one of the first stops 2021 is a fixed stop, locked on the support platform 201, and the other first stop 2021 is slidably connected to the support platform 201; or, both first stops 2021 are slidably connected to the support platform 201. A second linear guide pair 203 is arranged on the support platform 201 along the second direction Y. A sliding first stop 2021 is assembled on the second linear guide pair 203 and can slide linearly back and forth along the second direction Y. When the two first stops 2021 are close to each other, they clamp the battery module in the second direction Y; when the two first stops 2021 are far apart, they release the constraint on the battery module in the Y direction. The working end face of the stop and the battery module is made of nylon wear-resistant pad to avoid direct squeezing and scratching the surface of the battery module shell.

[0058] A pair of second stops 2022 are respectively disposed on both sides of the support portion 2011 along the first direction X. At least one of the second stops 2022 is slidably connected to the support platform 201. The pair of second stops 2022 can move closer to or further away from each other along the first direction X to clamp or release the battery module. It can be understood that one of the second stops 2022 is a fixed stop, locked onto the support platform 201, while the other second stop 2022 is slidably connected to the support platform 201; or, both second stops 2022 are slidably connected to the support platform 201. A third linear guide pair 204 is arranged on the support platform 201 along the first direction X. The sliding second stops 2022 are assembled on the third linear guide pair 204 and can slide linearly back and forth along the first direction X. When the two second stops 2022 move closer to each other, they clamp the battery module in the first direction X; when the two second stops 2022 move further away from each other, they release the X-direction constraint on the battery module. The working end face of the baffle that contacts the battery module is made of nylon wear-resistant pad to avoid direct squeezing and scratching the surface of the battery module housing.

[0059] With this configuration, the first stop 2021 and the second stop 2022, arranged orthogonally, achieve battery module limiting and clamping on the support platform 201 of the module carrier 2, ensuring the consistency of the positioning reference in the shaping process. At the same time, the sliding and adjustable structure of the stop is adaptable to battery modules of different specifications, and the tooling is highly versatile. The lateral clamping method avoids the movement space of the shaping mechanism, adapts to the sliding in and out operation process of the carrier, and can resist the lateral expansion trend of the module during the shaping process, thereby improving the yield of battery module shaping.

[0060] Optionally, in some embodiments of this application, such as Figure 2 and Figure 3 As shown, the first locking member 301 is connected to one of the second stop members 2022, and the second locking member 302 is movably disposed on the frame 1 along the first direction X. When the second locking member 302 is in the first position, that is, when the second locking member 302 moves to connect with the first locking member 301, the first locking member 301 is adapted to push one of the second stop members 2022 against each other along the first direction X to move toward or away from the opposite second stop member 2022, so as to clamp or release the battery module.

[0061] In this embodiment, as Figure 2 As shown, one of the second stop members 2022 is slidably connected to the support platform 201, and the movable second stop member 2022 is provided with a first locking member 301. The other second stop member 2022 is a fixed stop block, serving as an X-axis positioning reference, and is locked onto the support platform 201. The movable second stop member 2022 can be displaced along the first X-axis away from the other second stop member 2022 on the opposite side.

[0062] Once the module carrier 2, carrying the battery module, has fully slid into the module placement station 101, the second locking member 302, driven by the locking drive member 303, extends along the first direction X to connect and engage with the first locking member 301. The second locking member 302, continuing to move forward, transmits axial thrust through the first locking member 301, pushing the movable second stop 2022 along the first direction X towards the opposite second stop 2022. The two second stops 2022 approach each other, thereby clamping the battery module placed on the support portion 2011 from both sides in the X direction. At this time, the lateral clamping and positioning of the battery module in the X direction is completed by the pushing force of the second locking member 302 on the frame side, eliminating the need for an additional independent X-direction clamping drive on the module carrier 2. Conversely, the second locking member 302 causes the first locking member 301 to retract in the opposite direction. The movable second stop 2022 moves back along the first direction X, away from the second stop 2022 on the opposite side. The two second stop members 2022 move away from each other, thus releasing the battery module. Subsequently, the second locking member 302 continues to retract in the opposite direction until it separates from the first locking member 301, releasing the locking constraint on the module carrier 2.

[0063] This configuration integrates the first locking element 301 and the movable second stop element 2022 into a single unit. Utilizing the X-axis driving force of the second locking element 302 on the frame side, it simultaneously achieves two functions: carrier locking and battery module X-axis clamping. Specifically, it works with the first locking element 301 to lock the carrier and drives the second stop element 2022 to complete the battery module X-axis clamping action. This eliminates the need for additional X-axis drive components on the module carrier 2, reducing the number of power components on the carrier and simplifying its structure. Furthermore, the linkage between the module X-axis clamping and carrier locking actions prevents pressure shaping from being performed before the module is properly clamped, preventing module movement and damage, and improving equipment operational safety.

[0064] Optionally, in some embodiments of this application, such as Figure 2 As shown, the module positioning mechanism 202 also includes a positioning drive component 2023, which is mounted on the support platform 201. The positioning drive component 2023 drives a pair of first stops 2021 to move closer or further apart along the second direction Y to clamp or release the battery module. When the battery module to be shaped is placed on the carrier 2011, the positioning drive component 2023 receives a control system signal and drives the first stops 2021 on both sides to move towards each other along the second direction Y, bringing the pair of first stops closer together and clamping the battery module from both sides in the Y direction, thus completing the Y-direction clamping and positioning. Conversely, the positioning drive component 2023 drives the first stops 2021 on both sides to move away from each other, releasing the Y-direction lateral constraint on the battery module and releasing the module.

[0065] With this configuration, the positioning drive component 2023 directly drives a pair of first stops 2021 to move closer or further apart along the second direction Y, applying lateral constraint forces from the battery module Y to both sides, restricting the battery module's Y-axis translation and planar rotational freedom. Together with the X-axis clamping mechanism, this achieves reliable positioning of the battery module in the XY plane, ensuring consistency in the battery module shaping process, preventing module skew, and improving module positioning accuracy. By controlling the clamping force output by the positioning drive component 2023, an appropriate clamping force can be matched according to the strength of different module housings, ensuring the stability of the battery module during shaping and preventing excessive pressure from damaging the module housing.

[0066] Optionally, in some embodiments of this application, such as Figure 2 As shown, the positioning drive assembly 2023 includes a pair of third drive members 20231, which are respectively disposed corresponding to a pair of first stop members 2021. The third drive members 20231 are used to drive the corresponding first stop members 2021 to move along the second direction Y. The pair of third drive members 20231 are respectively disposed on both sides of the support platform 201 along the second direction Y. In this embodiment, the third drive members 20231 are respectively arranged on opposite sides of the support platform 201 along the second direction Y. The third drive members 20231 on both sides are connected one-to-one to the first stop members 2021 on the same side. Both first stop members 2021 can slide independently relative to the support platform 201 along the second direction Y. Optionally, the third drive members 20231 can be cylinders, servo motors and ball screw transmission structures, etc.

[0067] During operation, after the battery module is placed on the support unit 2011, the control system outputs control signals to the third drive members 20231 on both sides. The third drive members 20231 on both sides extend synchronously, pushing their respective first stop members 2021 towards the center of the support unit 2011. The pair of first stop members 2021 move closer to each other, clamping the battery module from the Y direction to both sides. Conversely, the third drive members 20231 on both sides drive the first stop members 2021 on both sides away from each other, releasing the lateral constraint on the battery module and realizing the relaxation of the module.

[0068] With this configuration, the first stop members 2021 on both sides are each driven by a separate third drive member 20231, making operation more flexible. It can control the synchronous feeding of both sides to achieve automatic centering and clamping of the battery module; it can also control the two stop members to make different stroke displacements to adapt to asymmetrical shapes and offset battery modules, thus expanding the tooling adaptability range.

[0069] Optionally, in some embodiments of this application, such as Figure 5As shown, the battery module shaping and pressurizing equipment also has a second direction Y perpendicular to the third direction Z. The module shaping mechanism 4 includes a first transport bracket 401, a first transport drive assembly 402, a second transport bracket 403, a second transport drive assembly 404, a first pressing assembly 405, and a second pressing assembly 406. Specifically, the first transport bracket 401 is slidably connected to the frame 1 along the second direction Y, and the first transport bracket 401 is located above the module placement station 101 along the third direction Z. In this embodiment, as... Figure 5 As shown, two sets of parallel fourth linear guide pairs 408 are mounted on the top of the frame 1 along the second direction Y. The first transport bracket 401 is mounted on the fourth linear guide pairs 408 and can slide linearly back and forth along the second direction Y. The whole structure spans the area above the module placement station 101, providing an upper mounting reference for the shaping operation of the battery module below. The first transport drive assembly 402 is disposed on the frame 1 and is connected to the first transport bracket 401. The first transport drive assembly 402 is used to drive the first transport bracket 401 to move along the second direction Y, so as to realize the overall Y-axis position adjustment of the module shaping mechanism 4 and ensure that the module shaping mechanism 4 is aligned with the battery module to be shaped below.

[0070] The second transport bracket 403 is slidably connected to the first transport bracket 401 along the third direction Z. Optionally, as follows: Figure 5 and Figure 7 As shown, the first transport bracket 401 is equipped with a fifth linear guide pair 409 extending along the third direction Z. The second transport bracket 403 is mounted on the fifth linear guide pair 409, allowing the second transport bracket 403 to slide up and down relative to the first transport bracket 401 along the third direction Z. The second transport drive assembly 404 is disposed on the first transport bracket 401 and connected to the second transport bracket 403. The second transport drive assembly 404 is used to drive the second transport bracket 403 to move along the third direction Z, so as to realize the Z-axis position adjustment of the shaping and pressurizing mechanism and adjust it to a suitable height position above the battery module.

[0071] The first clamping component 405 is disposed on the second transport bracket 403. The first clamping component 405 is used to clamp the battery module along the second direction Y, thereby applying a horizontal extrusion force in the Y direction to the battery module and realizing the side shaping and correction of the battery module in the Y direction. The second clamping component 406 is disposed on the second transport bracket 403. The second clamping component 406 is used to clamp the battery module along the third direction Z, thereby outputting shaping pressure downward in the Z direction and applying a downward clamping force to the upper surface of the battery module to complete the vertical shaping and pressurizing operation of the battery module.

[0072] During operation, the module carrier 2 carrying the battery modules slides into the module placement station 101, completing the carrier locking and positioning and clamping of the battery modules in the X and Y directions; the control system controls the first transport drive assembly 402 to work, driving the first transport bracket 401 to move along the second direction Y to the target position for the shaping operation; then the second transport drive assembly 404 drives the second transport bracket 403 to move downward along the third direction Z, causing the first clamping assembly 405 and the second clamping assembly 406 to move to the working height; afterwards, the first clamping assembly 405 moves along the first direction Z to the second direction Z to the third direction Z to the fourth direction Z to the fifth ... The second clamping component 406 outputs lateral clamping force in the Y direction to perform Y-axis shaping on the battery module. In addition, the second clamping component 406 outputs pressure downward in the Z direction to complete the Z-axis pressurization and shaping of the battery module. After the shaping and pressure holding are completed, the first clamping component 405 and the second clamping component 406 release pressure and reset in sequence. The second transport drive component 404 drives the second transport bracket 403 to rise and retract, and the first transport drive component 402 drives the first transport bracket 401 back to the standby position. Then the carrier lock is released, and the module carrier 2 can flow out of the workstation.

[0073] This setup allows for the rapid adjustment of the entire clamping assembly to the target position above the module via Y-axis movement, followed by Z-axis descent towards the battery module. This effectively ensures the precision of the shaping operation, avoids friction and interference between the clamping assembly and the module during Y-axis lateral movement, eliminates the need to adjust the battery module's position throughout the process, and prevents repeated positioning deviations caused by secondary module handling. This fundamentally solves the problems of insufficient shaping precision and poor product consistency. The entire clamping assembly is dynamically arranged; by adjusting the Y-axis stopping position and Z-axis descent stroke, the clamping assembly can be aligned with the pressure area of ​​the battery module. This adaptable design allows for the use of various battery module specifications, improving equipment flexibility and reducing the need for spare parts replacement.

[0074] Optionally, in some embodiments of this application, such as Figure 5 and Figure 6As shown, the first transport drive assembly 402 includes a first transport drive component 4021, a lead screw 4022, and a slide 4023. The first transport drive component 4021 is mounted on the frame 1. The lead screw 4022 extends along the second direction Y and is connected to the first transport drive component 4021. The first transport drive component 4021 drives the lead screw 4022 to rotate. Optionally, the first transport drive component 4021 can be a servo motor, a stepper motor, a hydraulic motor, etc. The output shaft of the first transport drive component 4021 can be connected to the lead screw 4022 via a coupling. The two ends of the lead screw 4022 are rotatably supported on the frame 1 via bearing seats. The slide 4023 is connected to the first transport bracket 401. The slide 4023 has a threaded hole that extends along the second direction Y and is adapted to the lead screw 4022. The lead screw 4022 is screwed into the threaded hole. Optionally, the slide 4023 can be fastened to the first transport bracket 401 by bolts, and the slide 4023 and the lead screw 4022 form a lead screw nut pair, which converts the rotational motion of the lead screw 4022 into the linear motion of the slide 4023 along the second direction Y.

[0075] During operation, the first conveying drive component 4021 receives a torque output from the control system, which drives the lead screw 4022 to rotate. The rotating lead screw 4022 drives the slide block 4023 to perform linear reciprocating motion along the axis of the lead screw 4022, i.e., the second direction Y, through the threaded pair. The slide block 4023 simultaneously drives the fixed first conveying bracket 401 to complete lateral displacement along the second direction Y, thereby adjusting the second conveying bracket 403, the first clamping component 405, and the second clamping component 406 mounted on the first conveying bracket 401 to the target working position above the battery module.

[0076] With this configuration, the first transport drive assembly 402 adopts a lead screw and nut precision transmission structure, which features high positioning accuracy, good displacement stability, simple integrated transmission link, strong structural rigidity, and excellent impact resistance. This enables precise, stable, and controllable lateral displacement of the first transport bracket 401 along the second direction Y, ensuring the alignment accuracy of the clamping assembly and meeting the high-precision, high-stability automated shaping process requirements of battery modules. Furthermore, in some embodiments, the first transport drive assembly 402 can also employ linear drive mechanisms such as cylinders or electric push rods to adjust the position of the first transport bracket 401 along the second direction Y.

[0077] Optionally, in some embodiments of this application, such as Figure 5 and Figure 7As shown, the second transport drive assembly 404 includes a second transport drive component 4041 and a sliding component 4042. The second transport drive component 4041 is mounted on the first transport bracket 401 and moves laterally along the second direction Y along with the first transport bracket 401. The second transport drive component 4041 is connected to the second transport bracket 403 and is used to drive the second transport bracket 403 to move along the third direction Z. Optionally, the second transport drive component 4041 can be a servo electric cylinder, pneumatic cylinder, etc. The output piston rod of the second transport drive component 4041 extends downward along the third direction Z, and the end of the piston rod is fixedly connected to the top surface of the second transport bracket 403 through a flange connecting plate. The second transport drive component 4041 can control the lifting and lowering displacement of the second transport bracket 403. The second transport drive component 4041 receives commands from the control system and drives the second transport bracket 403 to perform reciprocating lifting and lowering motion along the third direction Z.

[0078] The sliding component 4042 is slidably connected to the first transport bracket 401 along the third direction Z, and is also connected to the second transport bracket 403. Optionally, a fifth linear guide pair 409 extending along the third direction Z is installed on the side of the upright plate of the first transport bracket 401, and the sliding component 4042 is installed on the fifth linear guide pair 409, so that the second transport bracket 403 can slide up and down relative to the first transport bracket 401 along the third direction Z. To further improve motion stability, multiple sets of the second transport drive component 4041 and the sliding component 4042 are evenly spaced on the second transport bracket 403 to ensure that the force on the second transport bracket 403 is balanced during the lifting process and to avoid skewness and jamming.

[0079] During operation, after the first transport bracket 401 moves along the second direction Y to the target lateral position and completes alignment, the control system activates the second transport drive component 4041 to push the second transport bracket 403 downward. The sliding component 4042 slides vertically along the guide rail to guide the movement trajectory of the second transport bracket 403, causing the first pressing component 405 and the second pressing component 406 installed on the second transport bracket 403 to descend together, approaching the battery module, until reaching the shaping operation height to perform pressure shaping. After the pressure shaping process is completed, the second transport drive component 4041 pulls the second transport bracket 403 upward along the third direction Z to reset, and the sliding component 4042 slides upward back to the high standby position.

[0080] With this configuration, the second transport drive 4041 provides vertical driving force, and the sliding component 4042 plays a constraining and guiding role. The two work together to ensure that the second transport bracket 403 can reliably move vertically up and down along the third direction Z, so that the pressing component always maintains a vertical posture when it descends, effectively improving the shaping and pressurizing accuracy. At the same time, it can accurately control the downward position and adapt to battery modules of different height specifications.

[0081] Optionally, in some embodiments of this application, such as Figure 5 and Figure 8 As shown, the first clamping assembly 405 includes a pair of opposing first clamping members 4051 and two sets of first clamping drive members 4052. The pair of first clamping members 4051 are spaced apart along the second direction Y, and both are slidably connected to the second transport bracket 403. The pair of first clamping members 4051 are used to clamp the battery module along the second direction Y. In this embodiment, the two first clamping members 4051 can move closer or further apart along the second direction Y, applying horizontal compressive force from the left and right sides of the battery module in the Y direction to complete the lateral shaping and correction of the module in the Y direction. Optionally, the working surface of the first clamping member 4051 in contact with the battery module is equipped with a removable nylon buffer pad to prevent rigid compression from scratching the battery module casing, while also buffering the impact load during pressurization.

[0082] Two sets of first clamping drive members 4052 are respectively configured corresponding to a pair of first clamping members 4051, and the two sets of first clamping drive members 4052 are respectively configured on both sides of the second transport bracket 403 along the second direction Y. One set of first clamping drive members 4052 is used to drive the corresponding first clamping member 4051 to move along the second direction Y. Optionally, the first clamping drive member 4052 is selected from servo electric cylinders, pneumatic cylinders, etc., and the output piston rod of the first clamping drive member 4052 is connected to the corresponding first clamping member 4051. In order to further improve the motion stability, each first clamping member 4051 can be provided with at least two second transport drive members 4041 at intervals along the first direction X. At least two second transport drive members 4041 extend and retract synchronously, jointly driving the corresponding first clamping member 4051 to reciprocate along the second direction Y.

[0083] During operation, the first transport bracket 401 moves laterally along the Y direction to complete the lateral alignment; the second transport drive assembly 404 drives the second transport bracket 403 to descend along the third direction Z to the shaping working height; then the control system controls the first pressing drive members 4052 on both sides to extend synchronously, driving the two first pressing members 4051 on the left and right to feed towards each other, and the pair of first pressing members 4051 move closer to each other along the second direction Y, applying lateral pressure from both sides of the battery module to pressurize and shape the module in the Y direction and maintain pressure; after the lateral shaping is completed, the two sets of first pressing drive members 4052 drive the pair of first pressing members 4051 to move away from each other, releasing the battery module.

[0084] With this configuration, the two first clamping members 4051 are each driven by an independent first clamping drive member 4052. The two clamping members on both sides are fed synchronously towards each other, applying pressure from the Y direction of the battery module to both sides simultaneously. The module automatically centers during the pressurization process, and the force on both sides is balanced, which can effectively correct the Y-direction deformation of the module and avoid the module offset and skew problems caused by unilateral pressure, thus improving the dimensional consistency of the module after lateral shaping. At the same time, the drive stroke can be adjusted to adapt to battery modules with different Y-direction size specifications, without the need to replace a large number of tooling parts, thereby improving the flexible production capability of the equipment.

[0085] Optionally, in some embodiments of this application, such as Figure 8 and Figure 9 As shown, the second clamping assembly 406 includes a second clamping member 4061 and a second clamping drive member 4062. The second clamping member 4061 is slidably connected to the second transport bracket 403 along the third direction Z, and the second clamping member 4061 is located between a pair of first clamping members 4051 along the second direction Y. It can be understood that the second clamping member 4061 is located in the middle region between the two lateral clamping members, and applies shaping pressure vertically downward from the upper surface of the battery module to complete the vertical pressure shaping operation of the module.

[0086] The second clamping drive 4062 is connected to the second clamping member 4061, and the second clamping drive 4062 is used to drive the second clamping member 4061 to move along the third direction Z. Optionally, the second clamping drive 4062 is a servo electric cylinder, pneumatic cylinder, etc., and the second clamping drive 4062 is vertically fixed on the second transport bracket 403. The output piston rod is arranged downward along the third direction Z and connected to the second clamping member 4061. In order to further improve the motion stability, at least two second clamping drive members 4062 can be provided at intervals along the first direction X. The at least two second clamping drive members 4062 extend and retract synchronously, and jointly drive the second clamping member 4061 to reciprocate along the third direction Z.

[0087] During operation, the module carrier 2 slides into the workstation and locks, and the battery module completes X and Y lateral positioning and clamping; the first transport bracket 401 moves along the second direction Y to the target alignment position; the second transport drive assembly 404 drives the second transport bracket 403 to descend to the shaping working height; the first clamping drive members 4052 on both sides drive a pair of first clamping members 4051 to feed towards each other, clamping the battery module from Y to both sides to complete lateral shaping; then the second clamping drive member 4062 is activated, driving the second clamping member 4061 to slide downward along the third direction Z, passing through the space between the pair of first clamping members 4051, pressing down to contact the top surface of the battery module, applying vertical shaping pressure and maintaining the set holding pressure time; after the holding pressure ends, the second clamping drive member 4062 drives the second clamping member 4061 to move upward to reset, the first clamping member 4051 is released, and the second transport bracket 403 is raised to the high position, completing one round of shaping operation.

[0088] With this configuration, the second clamping component 4061 is positioned between the two first clamping components 4051 in the second direction Y. The overall spatial layout is ingenious and compact, and the lateral and vertical shaping movements do not interfere with each other, achieving bidirectional synchronous pressure shaping and high process flexibility. The two sets of clamping components share the second transport bracket 403 as the motion base, and bidirectional shaping point calibration can be completed in one alignment, resulting in high shaping accuracy and suitability for automated battery module shaping production lines. Furthermore, the downward pressure stroke can be adjusted to accommodate battery modules of different heights, demonstrating strong tooling versatility.

[0089] Optionally, in some embodiments of this application, such as Figure 9 and Figure 10 As shown, the second pressing assembly 406 further includes multiple rolling rollers 4063 and multiple elastic members 4064. The multiple rolling rollers 4063 are rotatably disposed at the end of the second pressing assembly 4061 facing the battery module, and are used to press against the battery module. The multiple elastic members 4064 are respectively disposed corresponding to the multiple rolling rollers 4063, and are disposed along the third direction Z. One end of each elastic member 4064 is connected to the second pressing assembly 4061, and the other end is connected to the corresponding rolling roller 4063.

[0090] In this embodiment, the lower end of the second clamping member 4061 has multiple sets of arrayed mounting cavities. Each mounting cavity includes a first mounting hole 40611 and a second mounting hole 40612 extending and communicating along a third direction (Z). The second mounting hole 40612 is located at the end of the first mounting hole 40611 furthest from the battery module, and the diameter of the second mounting hole 40612 is larger than the diameter of the first mounting hole 40611, forming a stepped surface 40613 at their hinge position. Each rolling roller 4063 includes a roller portion 40631, a connecting seat 40632, a connecting rod 40633, and a limiting portion 40634. The roller portion 40631 is rotatably mounted on the connecting seat 40632 and is used to press against the upper surface of the battery module. The connecting rod 40633 extends along a third direction (Z), with one end facing the battery module fixedly connected to the connecting seat 40632, and the other end fixedly connected to the limiting portion 40634. A connecting rod 40633 passes through the first mounting hole 40611. A wear-resistant sleeve 4065 is provided between the connecting rod 40633 and the first mounting hole 40611, and the wear-resistant sleeve 4065 is fitted over the connecting rod 40633. A limiting part 40634 is located in the second mounting hole 40612 and abuts against the stepped surface 40613. The elastic element 4064 can be a spring. The elastic element 4064 is provided in the second mounting hole 40612, with its top end abutting against the top wall of the first mounting hole 40611 and its other end abutting against the limiting part 40634. The rolling roller 4063 extends downward under the elastic force of the elastic element 4064 in an unloaded state. When the rolling roller 4063 is subjected to the upward reaction force of the battery module, it can overcome the elastic force of the elastic element 4064 and retract upward relative to the second pressing part 4061 in the third direction Z, realizing floating buffer.

[0091] During operation, when the second pressing drive 4062 drives the second pressing member 4061 to feed downward, multiple rolling rollers 4063 contact the upper surface of the battery module. As the second pressing member 4061 continues to descend, the elastic member 4064 is compressed, and each rolling roller 4063 applies a pressing load to the battery module by relying on the elastic force of the elastic member 4064. If there is a slight deviation on the upper surface of the battery module, the rolling roller 4063 at the corresponding position can independently retract upward, and the height difference is adaptively compensated by its respective elastic member 4064 to ensure that all rolling rollers 4063 can fit against the module surface and apply pressure evenly.

[0092] With this configuration, each rolling roller 4063 forms a floating pressure point through an independent elastic element 4064. A single rolling roller 4063 can independently extend and retract along the Z-axis, automatically compensating for the flatness error of the module surface. This avoids overpressure at localized points and insufficient pressure at other points, resulting in more uniform forming pressure on the top surface of the module, improving the consistency of module forming, and enhancing the overall forming quality. Simultaneously, the rolling roller 4063 can rotate, enabling rolling leveling and reducing frictional damage to the module surface.

[0093] Optionally, in some embodiments of this application, such as Figure 8 As shown, the battery module shaping and pressurizing equipment also has a first direction X, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The module shaping mechanism 4 also includes a pair of detection components 407, which are connected to the frame 1 and are located at both ends of the module carrier 2 along the first direction X. The pair of detection components 407 are used to detect the dimensions of the battery module along the first direction X. In this embodiment, the detection components 407 can be laser displacement sensors, vision cameras, etc., and are set on the outer sides of the two ends of the module carrier 2 along the first direction X. After the shaping operation is completed, the control system issues a detection command, and the detection components 407 on both sides perform online detection of the X-direction dimension of the shaped battery module. The detection data can be uploaded to the equipment control system to determine whether the shaping result is qualified. If the detection result is qualified, the carrier locking mechanism 3 releases the locking constraint between the module carrier 2 and the frame 1, and the module carrier 2 can smoothly slide out of the workstation to complete the unloading and transfer; if the detection result is unqualified, the equipment can directly alarm, and the next step of the operation can only be carried out after the abnormality is manually investigated and handled.

[0094] With this configuration, the detection components 407 arranged on both sides of the module carrier 2 along the first direction X can realize online real-time detection of the X-axis dimension of the battery module after shaping, timely feedback on the shaping effect, effectively intercept unqualified modules, prevent unqualified products from flowing to downstream processes, significantly improve the finished product yield of battery modules, and adapt to the mass production and automated production line operation of power battery modules.

The derivation process of this beneficial effect is largely similar to the derivation process of the beneficial effects of the battery module shaping and pressurizing equipment described above, and therefore will not be repeated here.

[0096] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and all such modifications and variations fall within the scope defined by the appended claims.
