Description

Technical Field

[0001] This disclosure relates to the field of battery system assembly technology, and in particular to a module loading device and a module loading method. Background Technology

[0002] With the advancement of global energy structure transformation, the new energy industry is entering a period of rapid development. As the core energy supply component of new energy equipment, the efficiency, consistency, and safety of battery module manufacturing directly determine the quality and reliability of the end product. In the PACK assembly process of power batteries, battery module installation is a crucial step. The core requirement is to accurately, stably, and safely install qualified battery modules into the corresponding mounting cavities of the PACK enclosure, laying a solid foundation for subsequent electrical connections, sealing tests, and factory assembly. Currently, in the field of battery module packing production, existing technologies have not yet formed a mature and effective fully automated packing solution. Most production scenarios still rely on manual assistance or semi-automated equipment to complete the packing operation. Manual packing is not only labor-intensive and inefficient, but the subjectivity and instability of manual operation can easily lead to problems such as tilting, jamming, and scratches during the packing process, making it impossible to guarantee packing accuracy and consistency. At the same time, there are also safety hazards caused by human error, making it difficult to adapt to the needs of large-scale, high-precision battery module production. While some semi-automated battery module loading equipment attempts to replace manual labor in some operations, it generally suffers from defects such as unreasonable structural design and poor coordination: either it only has a single gripping and transferring mechanism, lacking effective support and attitude leveling for the battery modules, causing the modules to tilt or shift during transfer and loading, leading to jamming or scratches; or it does not stably position the box, making it prone to shaking during loading and affecting loading accuracy; or it does not have a dedicated auxiliary support mechanism, making it easy for the module to deform due to excessive force on one end, failing to meet the high requirements of battery module loading safety and consistency. In summary, the existing technology lacks a module loading equipment and method that can achieve fully automated loading of battery modules and has advantages such as reasonable structure, good coordination, high loading accuracy, strong safety, and wide versatility. This cannot meet the needs of large-scale and high-precision production of new energy battery modules. Therefore, developing an efficient, accurate, and safe module loading equipment and method has become an urgent technical problem to be solved.

[0021] like Figures 1 to 10 As shown in the figure, this application embodiment provides a module loading device, including: a first side mechanism 1, a box conveyor line 2, and a second side mechanism 3. The first side mechanism 1 includes a robotic arm 11 and a module fixture 12. The module fixture 12 includes an outer frame 121, a movable frame 122, a module support part 123, and a module leveling part 124. The outer frame 121 is connected to the robotic arm 11. The movable frame 122 is movably disposed on the outer frame 121. The module support part 123 and the module leveling part 124 are both disposed on the movable frame 122. The module support part 123 is used to support one end of a battery module 5, and the module leveling part 124 is used to level the battery module 5. The box conveyor line 2 is used to carry and convey the box 21, and the box 21 has multiple mounting cavities 211. The second side mechanism 3 and the first side mechanism 1 are respectively located on both sides of the housing conveyor line 2. The second side mechanism 3 is used to support the other end of the battery module 5. The first side mechanism 1 and the second side mechanism 3 cooperate to install the battery module 5 into the mounting cavity 211.

[0022] The first side mechanism 1 is the core actuator of this equipment. It mainly undertakes the functions of gripping, adjusting the posture, transferring and guiding the battery module 5 into the box. Its structure includes a robotic arm 11 and a module fixture 12, which are connected. The robotic arm 11 can drive the module fixture 12 to move, thereby moving the position of the battery module 5 and ensuring stability and accuracy during the transfer process.

[0023] The robotic arm 11 can be a multi-degree-of-freedom industrial robot (e.g., a six-axis robot or other robots). Its end effector is connected to the outer frame 121 of the module fixture 12, enabling precise movement, rotation, and positioning in three-dimensional space. The robotic arm 11 has a preset motion program and can adjust its posture in real time based on the coordinate information fed back by the vision positioning system 1218, driving the module fixture 12 and the grasped battery module 5 to complete the transfer, alignment, and placement actions from the material handling station to the mounting cavity 211 of the housing 21. The motion accuracy of the robotic arm 11 can reach ±0.1mm, meeting the high-precision positioning requirements for the battery module 5 to be placed in the housing, while also having good load capacity, adaptable to battery modules 5 of different specifications and weights. The robotic arm 11 and the outer frame 121 can be connected by a rotary mechanism. The rotary mechanism can drive the outer frame 121 to rotate relative to the robotic arm 11, adjust the posture of the outer frame 121, so as to facilitate the module fixture 12 to grasp the battery module 5 or to facilitate the module fixture 12 to accurately transfer the battery module 5 into the mounting cavity 211.

[0024] The module fixture 12 is a component that directly contacts the battery module 5 and is used to support, position and level the module. Its structure includes an outer frame 121, a movable frame 122, a module support part 123 and a module leveling part 124. All components work together to ensure that the module is stable and level during transportation and boxing.

[0025] The outer frame 121, serving as the basic load-bearing structure of the module tooling 12, can be made of high-strength aluminum alloy, featuring a stable structure, light weight, and good rigidity, effectively bearing the weight of the battery module 5 and the inertial forces during transportation. One end of the outer frame 121 is fixedly connected to the end of the robotic arm 11, while the other end provides an installation reference for the movable frame 122, ensuring that the movement trajectory of the movable frame 122 is precise and controllable.

[0026] The movable frame 122 is movably mounted on the outer frame 121. Specifically, it can be slidably connected to the outer frame 121 via a slide rail, enabling reciprocating movement along the length of the outer frame 121. The movement of the movable frame 122 can be driven by a drive component (such as a servo motor + lead screw transmission mechanism), and the movement accuracy can be precisely controlled. It is used to adjust the position of the module support part 123 and the module leveling part 124, facilitating the gripping of the battery module 5. Simultaneously, it coordinates with the box-insertion action to achieve smooth pushing of the module.

[0027] The module support 123 can be disposed at one end of the movable frame 122 to support one end of the battery module 5 (which can be the rear end of the module), and its structure is adapted to the shape of the battery module 5. The surface of the module support 123 can be covered with a flexible buffer layer 1233 (such as a polyurethane buffer pad) to avoid direct contact causing scratches or damage to the module shell. The module leveling part 124 is disposed on the movable frame 122 together with the module support 123, located beside or above the module support 123, and is used to level the battery module 5 to ensure that the module maintains a horizontal posture during transportation and box placement, eliminating problems such as box placement jamming or positioning deviation caused by module tilting.

[0028] In some implementations, the module support 123 includes a first stop 1231 and a plurality of first pins 1232 disposed on the first stop 1231. The first stop 1231 is located at the end of the movable frame 122 along the moving direction and is connected to the movable frame 122. The end plate 51 of the battery module 5 is provided with a first hole 511. The first hole 511 extends along the thickness direction of the end plate 51. When the first side mechanism 1 grips one end of the battery module 5, the first pins 1232 are inserted into the first hole 511, and the first stop 1231 is attached to the end plate 51 of the battery module 5.

[0029] The first stop 1231, serving as the basic load-bearing component of the module support 123, adopts a plate-shaped structure adapted to the shape of the battery module 5 end plate 51. It is made of a high-strength, wear-resistant alloy material with certain cushioning properties, and its surface can be covered with a flexible buffer layer 1233 (such as a polyurethane buffer pad). This ensures the rigidity of the support while preventing hard contact with the battery module 5 end plate 51, thus preventing scratches or damage to the end plate 51. The connection between the first stop 1231 and the movable frame 122 can be achieved using fasteners or welding, ensuring a secure connection and preventing relative displacement during the movement of the movable frame 122 and module transport, providing a stable reference for module support. The first pin 1232 is located on the side of the first stop 1231 facing the battery module 5 end plate 51. Its number depends on the structure and positioning requirements of the battery module 5 end plate 51, typically 2-4, and they are symmetrically distributed (preferably diagonally). This ensures positioning stability and prevents excessive local stress that could deform the module end plate 51. The dimensions of the first pin 1232 are precisely matched with the first hole 511 on the end plate 51 of the battery module 5. The outer diameter of the pin is slightly smaller than the inner diameter of the first hole 511, ensuring smooth insertion and preventing loosening after insertion, thus achieving precise positioning of the module. Simultaneously, the end of the first pin 1232 features a rounded corner design to prevent scratching the hole wall when inserted into the first hole 511, protecting the structural integrity of the end plate 51 of the battery module 5. The first hole 511 can be a pre-set process hole or positioning hole on the end plate 51 of the battery module 5, extending through the thickness of the end plate 51. Its position corresponds one-to-one with the first pin 1232 on the first stop 1231, ensuring that the first pin 1232 can be precisely inserted into the first hole 511 when the first side mechanism 1 grips the module. With the first side mechanism 1 gripping one end of the battery module 5, the first pin 1232 is fully inserted into the first hole 511, limiting the module in the horizontal direction and preventing horizontal displacement, rotation, or shaking during transport. Simultaneously, the first stop 1231 fits tightly against the end plate 51 of the battery module 5, providing axial support and bearing the module's weight and inertial forces during transport. This ensures the module's stability during gripping, transport, and placement in the box, laying the foundation for subsequent leveling and boxing operations. Furthermore, the connection between the first pin 1232 and the first stop 1231 can be detachable (e.g., threaded connection), facilitating the replacement of the first pin 1232 with the corresponding specification based on the position and size of the first hole 511 on the end plate 51 of different battery module 5 specifications. This improves the versatility of the module support 123, adapting to the production needs of different battery module models and further reducing equipment investment costs for enterprises.

[0030] The first pin 1232 may include a disc and a pin body of a vertical disc. The pin body is located on the central axis of the disc. Multiple connecting holes are provided on the disc around the circumference of the pin body to facilitate connection to the first stop body via multiple bolts. A flexible buffer layer 1233 may cover the surface of the first stop body. The surface of the flexible buffer layer 1233 is provided with clearance holes, and the disc is located within these clearance holes. The thickness of the flexible buffer layer 1233 is greater than that of the disc to prevent the rigid disc from contacting the end plate 51 of the battery module 5.

[0031] In some possible implementations, the module leveling part 124 includes a lifting mechanism movably disposed on the movable frame 122. The lifting mechanism's direction of movement is perpendicular to the first pin 1232. The battery module 5 has a water-cooled plate 52, which is perpendicular to the end plate 51 and extends out of the end plate 51. When the first side mechanism 1 grips one end of the battery module 5, the lifting mechanism abuts against the section of the water-cooled plate 52 that extends out of the end plate 51 to level the battery module 5.

[0032] The lifting mechanism is movably connected to the movable frame 122, and its direction of movement is perpendicular to the axis of the first pin 1232, i.e., perpendicular to the direction of the water-cooling plate 52. The first pin 1232 is perpendicular to the end plate 51 of the battery module 5. The lifting mechanism moves vertically along the direction perpendicular to the water-cooling plate 52, allowing for lifting and lowering adjustment along this direction. This is used to level the battery module 5, ensuring that the module maintains a horizontal posture during transportation and placement into the box, eliminating problems such as jamming or positioning deviation caused by module tilting. The module leveling part 124 can adopt a telescopic positioning pin structure, driven by a micro cylinder, and can extend and retract vertically. When the battery module 5 is supported by the module support part 123, the module leveling part 124 extends and presses downward against the water-cooling plate 52. By adjusting the lifting height of the lifting mechanism, the tilt angle of the battery module 5 can be corrected, ensuring that the bottom surface of the battery module 5 is parallel to the bottom wall of the mounting cavity 211 of the box 21.

[0033] As a heat dissipation component of the battery module 5, the water-cooled plate 52 possesses a certain structural strength, capable of withstanding the upward force of the lifting mechanism. Simultaneously, its extended end plate 51 design prevents interference with other parts of the battery module 5, such as the battery cells, during the leveling operation, balancing the leveling function with the module's structural safety. When the first side mechanism 1 grips one end of the battery module 5, the first pin 1232 of the module support part 123 inserts into the first hole 511 of the end plate 51 of the battery module 5, and the first stop 1231 abuts against the end plate 51, completing the initial positioning and support of the module. Then, the lifting mechanism of the module leveling part 124 activates, pressing against the section of the water-cooled plate 52 extending from the end plate 51. At this time, the lifting mechanism can adjust its extension length according to a preset horizontal reference or the real-time detected module posture. If the corresponding end of the battery module 5 is detected to be too high, the lifting mechanism retracts appropriately, lowering the height of that end; if the corresponding end is detected to be too low, the lifting mechanism extends appropriately, raising the height of that end, until the entire battery module 5 reaches a horizontal posture, completing the leveling operation. In addition, the lifting mechanism can be equipped with a displacement sensor to detect the extension length of the lifting mechanism in real time, thereby accurately controlling the lifting height and ensuring that the leveling accuracy can reach ±0.05mm, meeting the high-precision posture requirements of the battery module 5 when entering the box. At the same time, the lifting mechanism is linked with the module support 123 and the robotic arm 11, and maintains the top position after leveling until the module is completely placed in the box, avoiding the displacement of the module posture during transportation and boxing. This implementation scheme uses the water-cooled plate 52 of the battery module 5 itself as the leveling force point, eliminating the need for additional matching structures on the battery module 5, simplifying the module structure design. At the same time, the adjustable design of the lifting mechanism also improves the versatility of the module leveling part 124, adapting to the leveling requirements of battery modules 5 with different specifications and different posture deviations.

[0034] In some possible implementations, the lifting mechanism includes a lifting drive, a second stop 1241, and a second pin 1242 disposed on the second stop 1241. The lifting drive is disposed on the movable frame 122, and the second stop 1241 is connected to the lifting drive. A second hole 521 is provided on the section of the water-cooled plate 52 that extends out of the end plate 51. When the first side mechanism 1 grips one end of the battery module 5, the lifting drive extends, so that the second pin 1242 is inserted into the second hole 521, and the second stop 1241 abuts against the water-cooled plate 52.

[0035] The lifting drive component serves as the power source for the lifting mechanism in this implementation scheme. Its selection is adapted to the leveling accuracy and load requirements of the lifting mechanism. A miniature servo cylinder or an electric push rod can be selected. Compared with ordinary cylinders, it has the advantages of precise and controllable stroke, smooth start and stop, and adjustable thrust. It can accurately control the lifting height and ensure that the leveling accuracy meets the stringent requirements of the battery module 5 entering the box. The cylinder body of the lifting drive component is rigidly fixed to the movable frame 122 by bolts. The second stop 1241 serves as the load-bearing and supporting component of the lifting mechanism. It adopts a plate-shaped structure that matches the shape of the protruding section of the water-cooled plate 52. The material is made of high-strength lightweight alloy, and the surface is covered with a flexible buffer layer 1233 (such as a wear-resistant rubber pad). This ensures the rigidity of its own structure, enabling it to withstand the driving force of the lifting drive component and the reaction force of the module, while avoiding hard contact with the water-cooled plate 52 to prevent scratches on the surface of the water-cooled plate 52 and damage to the internal pipes of the water-cooled plate 52. This balances the leveling stability and the safety of the module. The second stop 1241 is connected to the output end of the lifting drive component (such as the piston rod of a servo cylinder or the push rod of an electric push rod) to ensure that the second stop 1241 can move up and down synchronously when the lifting drive component is activated, without relative displacement, thus ensuring the synchronicity and reliability of the leveling action. The second pin 1242 is set on the side of the second stop 1241 facing the water-cooled plate 52. The number and position of the pins correspond one-to-one with the second holes 521 on the protruding section of the water-cooled plate 52. Usually, two pins are set in a symmetrical distribution, which not only ensures the stability of the positioning but also avoids excessive force on a single pin, which could cause deformation of the water-cooled plate 52 or damage to the holes. The outer diameter of the second pin 1242 is slightly smaller than the inner diameter of the second hole 521 to ensure smooth and secure insertion. The end features a rounded corner design to prevent scratching the hole wall during insertion. Simultaneously, the second pin 1242 and the second stop 1241 are detachably connected (e.g., by a threaded connection), allowing for easy replacement of the second pin 1242 with the appropriate size and position of the second hole 521 on different specifications of water-cooled plates 52. This enhances the versatility of the lifting mechanism and adapts to the leveling requirements of different battery module models 5. The second hole 521 is a pre-set positioning hole on the protruding end plate 51 section of the water-cooled plate 52. The second hole 521 requires no additional machining and can be completed simultaneously with the production process of the water-cooled plate 52, without increasing the module's processing cost.The specific working process is as follows: When the first side mechanism 1 grasps one end of the battery module 5, the first pin 1232 of the module support part 123 is inserted into the first hole 511 of the end plate 51, and the first stop 1231 is attached to the end plate 51 to complete the initial positioning. Then, the lifting drive component starts and extends, driving the second stop 1241 and the second pin 1242 to move synchronously towards the water-cooled plate 52 until the second pin 1242 is precisely inserted into the second hole 521 of the water-cooled plate 52, and at the same time, the second stop 1241 is tightly abutted against the plate surface of the section of the water-cooled plate 52 that protrudes from the end plate 51. At this time, if the corresponding end of the battery module 5 is detected to be tilted, the lifting drive component will adjust the position precisely. The elongation of the module drives the second stop 1241 and the water-cooling plate 52 to rise and fall synchronously, thereby adjusting the height of the end of the battery module 5 until the module as a whole reaches a horizontal position. After leveling, the lifting drive maintains the current elongation state. The module's posture is firmly fixed by the insertion and positioning of the second pin 1242 and the second hole 521, and the support of the second stop 1241, preventing the module from tilting or shifting during transportation and placement into the box. After the module is fully placed into the box, the lifting drive retracts, causing the second pin 1242 to be pulled out of the second hole 521. The second stop 1241 separates from the water-cooling plate 52, completing the leveling action and resetting without interfering with subsequent processes.

[0036] In some possible implementations, the outer frame 121 encloses a receiving cavity, and the movable frame 122 is at least partially located in the receiving cavity. The first side mechanism 1 can drive the module tooling 12 to move, so that the outer frame 121 is fitted onto the outside of the battery module 5. The movable frame 122 can move the battery module 5 into or out of the receiving cavity. The outer frame 121 serves as both a carrier for the movable frame 122 and a protector of the module.

[0037] The outer frame 121 adopts a frame-type enclosed structure. The size of the hollow internal cavity is adapted to the external dimensions of the battery module 5, ensuring that the outer frame 121 can be smoothly fitted onto the outside of the battery module 5. After fitting, a reasonable buffer gap (usually 3-5mm) is reserved between the inner wall of the outer frame 121 and the outer shell of the battery module 5. This avoids scratches caused by hard contact between the outer frame 121 and the module, and also provides sufficient space for the movement of the movable frame 122 and the insertion and removal of the module. The movable frame 122, as an internal component of the outer frame 121, has an overall structure that matches the cavity and is at least partially embedded inside the cavity. The module insertion device includes a first drive mechanism 1217. A slide rail 1216 is provided on the inner wall of the outer frame 121. A movable frame is slidably connected to the slide rail 1216. The first drive mechanism 1217 is disposed on the outer frame 121. The first drive mechanism 1217 and the movable frame 122 are in a transmission cooperation to drive the movable frame 122 to extend or retract into the receiving cavity. The slide rail 1216 ensures that the movable frame 122 can move smoothly along the length direction of the receiving cavity (i.e., towards or away from the opening of the outer frame 121) without deviation or jamming during the movement. The part of the movable frame 122 embedded in the receiving cavity does not contact the inner wall of the outer frame 121, and is only connected through the slide rail 1216, reducing friction during the movement and improving the accuracy and smoothness of the movement. When the first side mechanism 1 drives the module fixture 12 to move, the robotic arm 11 moves the outer frame 121 as a whole, aligning the open end of the outer frame 121 with the battery module 5. Then, the robotic arm 11 fine-tunes its position, slowly fitting the outer frame 121 onto the outside of the battery module 5, completing the fitting operation of the outer frame 121. At this time, the module support part 123 and the module leveling part 124 on the movable frame 122 can accurately align with the battery module 5, completing the gripping, positioning, and leveling of the module. After the module is positioned and leveled, the robotic arm 11 moves the outer frame 121 to one side opening of the mounting cavity 211. Driven by the first drive mechanism 1217, the movable frame 122 moves along the length of the receiving cavity, slowly moving the battery module 5 into the cavity until the entire module is completely within its range. During transport and placement, the movable frame 122 can move the battery module 5 from the receiving cavity towards the mounting cavity 211 of the box 21 according to the placement requirements, ensuring smooth placement of the module. The first drive mechanism 1217 may include a lead screw and a motor that drives the lead screw to rotate; the lead screw is threadedly connected to the movable frame 122.

[0038] In some possible implementations, the outer frame 121 has a top frame 1211 and two side frames 1212, with the two side frames 1212 disposed on both sides of the top frame 1211. A plurality of support rollers 1213 are provided on the side of the side frame 1212 away from the top frame 1211. Each of the support rollers 1213 is arranged sequentially along the moving direction of the movable frame 122. When the battery module 5 is located in the receiving cavity, the bottom of the battery module 5 is supported by each of the support rollers 1213.

[0039] The top frame 1211 and the two side frames 1212 together constitute the main frame structure of the outer frame 121. The top frame 1211 is horizontally positioned, and the two side frames 1212 are perpendicular to the two sides of the top frame 1211, integrally formed with the top frame 1211 to form the frame base. The interior encloses and forms a complete receiving cavity, resulting in a stronger overall structural rigidity, which can better support the weight of the movable frame 122 and the battery module 5, while providing a stable installation reference for the support roller 1213. An installation position can be reserved on the side of the side frame 1212 away from the top frame 1211 for fixing the support roller 1213. The support roller 1213 can be made of high-strength wear-resistant alloy steel, with a rust-proof and wear-resistant surface treatment to extend its service life. Its outer diameter is matched with the buffer gap of the receiving cavity to ensure that after the battery module 5 is placed in the receiving cavity, the bottom can accurately fit the support roller 1213 without contacting the side frame 1212 or the bottom plate. The number of support rollers 1213 is reasonably set according to the length of the battery module 5. The support rollers 1213 on both side frames 1212 are symmetrically distributed to ensure that the bottom of the battery module 5 is evenly stressed and to avoid excessive local stress that could cause module deformation. Each support roller 1213 can be rotatably connected to the side frame 1212 through bearings, which allows for smooth rotation and low friction. It can rotate synchronously with the movement of the battery module 5, reducing the frictional resistance between the battery module 5 and the support rollers 1213. When the battery module 5 is located in the receiving cavity, the bottom of the battery module 5 is supported on each support roller 1213, forming a rolling support structure. When the movable frame 122 moves the battery module 5 into or out of the receiving cavity, the supporting roller 1213 rotates synchronously, converting the sliding friction between the battery module 5 and the outer frame 121 into rolling friction. This significantly reduces the friction during movement, making the movement of the module smoother and more stable, reducing jamming and improving movement accuracy. On the other hand, it prevents scratches caused by hard friction between the bottom of the battery module 5 and the outer frame 121, further protecting the integrity of the battery module 5's shell. This is especially suitable for heavier battery modules 5, effectively reducing the load on the drive components of the movable frame 122, reducing equipment wear, and improving the long-term operational stability of the equipment.

[0040] In some possible implementations, the module loading device includes a second drive mechanism 1214 and two side roller assemblies 1215. The two side roller assemblies 1215 are respectively disposed on the two side frames 1212. Each side roller assembly includes multiple side rollers, which are arranged sequentially along the moving direction of the movable frame 122. The second drive mechanism 1214 is disposed on the outer frame 121. The second drive mechanism 1214 is in a driving engagement with the side roller assemblies 1215 to drive the two side roller assemblies 1215 to move closer together or further apart, thereby clamping or releasing the battery module 5. The second drive mechanism 1214 may include two cylinders, which are respectively in a driving engagement with the two side roller assemblies 1215. The two cylinders extend and retract synchronously, driving the two side roller assemblies 1215 to move closer together or further apart, thereby clamping or releasing the battery module 5. The side roller assembly may include a roller frame and a plurality of side rollers mounted on the roller frame, the roller frame being slidably mounted on a side frame 1212 of the outer frame 121. A cylinder is mounted on the outer frame 121 and engages in a driving engagement with a corresponding roller frame.

[0041] The side roller assembly 1215 and the support roller 1213 cooperate to provide all-around support and positioning for the battery module 5. The support roller 1213 provides rolling support to the bottom of the battery module 5, while the side roller assembly 1215 clamps, limits, and guides the battery module 5 on both sides. Their coordinated operation further enhances the stability of the battery module 5 within the receiving cavity. The two side roller assemblies 1215 are respectively mounted on the two side frames 1212 of the outer frame 121, with the installation direction consistent with that of the support roller 1213. They are distributed along the moving direction of the movable frame 122, ensuring that the battery module 5 receives uniform clamping and guiding forces on both sides during insertion, removal from the receiving cavity, and transfer. The sliding direction of the roller frame is perpendicular to the moving direction of the movable frame 122, ensuring that the roller frame, driven by the second drive mechanism 1214, smoothly moves the side rollers closer together or further apart, achieving clamping and release of the battery module 5. The side rollers of the side roller assemblies 1215 are symmetrically distributed to ensure uniform force on both sides of the battery module 5, avoiding excessive local force that could cause scratches or deformation of the module shell. The side rollers can be made of flexible and wear-resistant materials (such as polyurethane-coated rollers) and wrapped with a flexible buffer layer 1233. This effectively increases the friction with the battery module 5 shell, improving clamping stability, and avoids scratches caused by hard contact. At the same time, the side rollers are rotatably connected to the roller frame through bearings, allowing for smooth rotation. They can rotate synchronously with the movement of the battery module 5, playing a guiding role and reducing frictional resistance during module movement, ensuring smooth and stable module movement. The second drive mechanism 1214, as the power source for the side roller assemblies 1215, is fixedly mounted on the top frame 1211 or side frame 1212 of the outer frame 121. It is in corresponding transmission cooperation with the side roller assemblies 1215, and its core function is to drive the side roller assemblies 1215 to move towards each other or away from each other. In this embodiment, the second drive mechanism 1214 preferably uses two cylinders. The two cylinders are respectively connected to the roller frames on both sides for transmission. The cylinder body is fixed on the outer frame 121, and the piston rod extends towards the roller frame and connects to the roller frame to ensure that the roller frame can be accurately driven to slide when the cylinder is activated. The two cylinders adopt a synchronous control method to achieve synchronous extension and retraction, thereby driving the roller assemblies 1215 on both sides to move closer or further away in opposite directions, ensuring that the clamping force on both sides of the battery module 5 is uniform and avoiding tilting or displacement of the module due to excessive clamping force on one side.The specific working process is as follows: When the robotic arm 11 moves the outer frame 121 to fit outside the battery module 5, after the bottom of the battery module 5 is supported on the support roller 1213, the second drive mechanism 1214 is activated, and the two cylinders extend synchronously, pushing the two side roller frames to slide into the receiving cavity, driving the side rollers to gradually approach the two sides of the battery module 5 until the side rollers are tightly attached to the outer shell of the battery module 5, realizing the clamping and limiting of the battery module 5. At this time, the battery module 5 is limited by the support roller 1213 at the bottom and the side rollers on both sides, forming a stable support in all directions, effectively preventing the battery module 5 from shifting left and right, tilting or shaking during the transfer process; when it is necessary to release the battery module 5, the second drive mechanism 1214 controls the two cylinders to retract synchronously, driving the two side roller frames to slide towards the side frame 1212, the side rollers separate from the outer shell of the battery module 5, releasing the clamping of the battery module 5, without interfering with the movable frame 122 moving the module into or out of the receiving cavity or the resetting operation of the robotic arm 11.

[0042] In some possible implementations, such as Figure 6 and Figure 7 As shown, the module loading equipment also includes a module transport line 4. Battery modules 5 are sequentially supported on the module transport line 4 and move horizontally along it. A tray 41 can be installed on the module transport line 4, and the battery modules 5 can be supported on the tray 41. A support body 411 is installed on the tray 41. The battery modules 5 are suspended on both sides along the width direction of the module transport line 4 on the central support body 411, without any supporting structure. Figure 4 and Figure 5 As shown, the outer frame 121 has an opening on one side, and two rows of support rollers 1213 are arranged on both sides of the bottom, with a gap between the two rows of support rollers 1213. The robotic arm 11 can adjust the outer frame 121 to move until the opening is located on one side of the battery module 5. At this time, the outer frame 121 is further controlled to move horizontally, so that the battery module 5 is fitted inside the outer frame 121. At this time, the support rollers 1213 at the bottom of the outer frame 121 support the bottom of the battery module 5. A vertical pin 412 can be provided on the tray 41, and the vertical pin 412 can be inserted into the positioning hole on the water cooling plate 52 of the battery module 5 on the tray 41.

[0043] The module transport line 4 serves as the transport carrier for the battery modules 5, smoothly conveying the battery modules 5 to the gripping station from the material handling station to the gripping station, achieving continuous transport of the battery modules 5 and improving overall production efficiency. The module transport line 4 can be equipped with a belt conveyor, chain conveyor, etc., and the conveying speed can be adjusted according to the overall production cycle. It operates smoothly during transport, preventing the battery modules 5 from shifting due to vibration, thus providing a stable reference for the subsequent outer frame 121 fitting operation. The pallet 41 is placed on the module transport line 4 and moves synchronously with the transport line. Its function is to provide temporary support for the battery modules 5 and, in conjunction with the outer frame 121, achieve precise fitting of the battery modules 5. The surface of the pallet 41 is flat and smooth, and its bottom fits tightly against the conveying surface of the transport line, ensuring that the pallet 41 does not shake or shift during transport. The support 411 on the tray 41 is located in the middle of the tray 41 and is adapted to the middle structure of the battery module 5. The height and shape of the support 411 are designed according to the bottom contour of the battery module 5, and a flexible support material (such as a polyurethane cushioning pad) is used to avoid hard contact with the bottom of the battery module 5 and cause scratches. At the same time, it ensures that the battery module 5 can be stably supported on the support 411 and will not tip over. The setting of the support 411 must meet the following requirements: after the battery module 5 is placed on the support 411, its two sides along the width direction of the module transport line 4 are suspended in the air without other support structures. The core purpose of this design is to reserve enough space for the fitting of the outer frame 121, to avoid the support structures on both sides of the tray 41 from interfering with the horizontal movement and fitting action of the outer frame 121, to ensure that the outer frame 121 can be smoothly fitted into the battery module 5 from one side, and to ensure the precise fit of the bottom support roller 1213 of the outer frame 121 with the bottom of the battery module 5. The support 411 can adopt a block, strip, or frame structure, which can be adjusted according to the weight and bottom structure of the battery module 5 to ensure the stability of the support and prevent the battery module 5 from shifting left or right during transportation. Correspondingly, the structure of the outer frame 121 is adapted to the suspended design of the tray 41 and the battery module 5: one side of the outer frame 121 has an open structure, and the opening size is slightly larger than the width of the battery module 5 to ensure that it can be smoothly fitted onto the outside of the battery module 5.The specific process of mounting the battery module 5 onto the outer frame 121 is as follows: After the module transport line 4 transports the tray 41 carrying the battery module 5 to the preset mounting station, the transport line stops running, and the tray 41 and the battery module 5 remain stationary; the robotic arm 11 drives the outer frame 121 to move as a whole. A vision positioning system 1218 is installed on the outer frame 121. The vision positioning system 1218 precisely adjusts the posture of the outer frame 121 so that the opening end of the outer frame 121 faces the side of the battery module 5, and the two rows of support rollers 1213 at the bottom of the outer frame 121 are aligned with the suspended area at the bottom of the battery module 5; subsequently... The robotic arm 11 controls the outer frame 121 to move slowly horizontally towards the battery module 5. Utilizing the suspended structure on both sides of the battery module 5, the outer frame 121 gradually fits into the battery module 5 from one side, completing the fitting operation. At this time, the two rows of support rollers 1213 at the bottom of the outer frame 121 precisely support the bottom sides of the battery module 5, replacing the support body 411 of the tray 41 to provide bottom support for the battery module 5. Simultaneously, the side roller assemblies 1215 on both sides of the battery module 5 correspond to those on the outer frame 121, preparing for subsequent clamping, module leveling, and transfer operations of the side roller assemblies 1215. In this implementation scheme, the cooperation between the module transport line 4 and the tray 41 achieves continuous and automated transport of the battery module 5, reducing manual intervention and improving production efficiency. The design of the support body 411 on the tray 41 and the suspended structure on both sides of the battery module 5 cleverly solves the interference problem when the outer frame 121 is fitted, ensuring that the outer frame 121 can be fitted quickly and accurately. The precise fit between the two rows of support rollers 1213 at the bottom of the outer frame 121 and the bottom of the battery module 5 not only achieves stable support for the battery module 5 after fitting, but also provides smooth rolling support for the subsequent moving frame 122 to move the battery module 5 into the receiving cavity, transfer and box, further improving the automation and operational stability of module boxing.

[0044] In some possible implementations, such as Figure 8 As shown, the second side mechanism 3 includes a frame 31, a lifting frame 32, and a telescopic frame 33. The lifting frame 32 is disposed on the frame 31 and can move up and down along the frame 31. The telescopic frame 33 is disposed on the lifting frame 32 and can extend or retract toward the first side mechanism 1. The telescopic frame 33 is used to support the other end of the battery module 5.

[0045] like Figure 1As shown, the housing 21 has multiple rows of mounting cavities 211, with each row of mounting cavities 211 arranged sequentially along the height of the housing 21. The module loading device can sequentially pick up each battery module 5 and assemble them into different mounting cavities 211. The height of the telescopic frame 33 can be adjusted by setting a lifting frame 32, which facilitates the assembly of battery modules 5 in different rows of mounting cavities 211. The loading device may also include a frame guide rail 6, with a frame 31 movably mounted on the frame guide rail 6. The frame 31 can be translated along the frame guide rail 6, and the position of the telescopic frame 33 can be adjusted to facilitate the assembly of battery modules 5 in different rows of mounting cavities 211. The housing conveyor line 2 is used to transport the housing 21. The frame guide rail 6 can be parallel to the housing conveyor line 2.

[0046] Sensors (such as proximity switches) can also be installed on the box conveyor line 2 to detect whether the box 21 is installed in place or in a preset position. If the box 21 is not in place, the equipment will issue an alarm signal and stop the boxing operation to ensure the safety of the equipment and products. The box 21 itself has multiple rows of mounting cavities 211. Each row of mounting cavities 211 is arranged sequentially along the height of the box 21. The multiple rows of mounting cavities 211 are evenly distributed along the length or width of the box 21, which can realize the layered, rowed, synchronous, or sequential boxing of multiple battery modules 5, greatly improving production efficiency and adapting to the needs of large-scale production. The module boxing equipment can sequentially pick up each battery module 5 according to a preset program and assemble them into mounting cavities 211 of different rows and heights, realizing automated and orderly module boxing operation.

[0047] To accommodate the assembly requirements of multiple rows and multiple layers of mounting cavities 211 in the housing 21, the module loading equipment is also equipped with a lifting frame 32, a frame guide rail 6, and a frame 31. The lifting frame 32 is used to adjust the height of the telescopic frame 33, facilitating auxiliary assembly of battery modules 5 in mounting cavities 211 at different heights. The frame guide rail 6 can extend along the arrangement direction of the multiple rows of mounting cavities 211, and the frame 31 is movably mounted on the frame guide rail 6, allowing it to move smoothly along the frame guide rail 6. This adjusts the horizontal position of the telescopic frame 33, facilitating auxiliary assembly of battery modules 5 in mounting cavities 211 at different rows, achieving full coverage assembly of multiple rows and multiple layers of mounting cavities 211 without the need for manual adjustment of the housing 21 or equipment position, further improving the automation level of loading.

[0048] Specifically, the lifting frame 32 is mounted on the chassis 31 and is connected to the telescopic frame 33 via a transmission mechanism. It can employ a hydraulic lifting mechanism or a screw lifting mechanism, featuring smooth lifting, adjustable height, and strong load capacity. Its lifting stroke is adapted to the height range of the mounting cavity 211 in the housing 21, allowing precise adjustment of the telescopic frame 33 to the corresponding height of any mounting cavity 211. This ensures that the auxiliary support and positioning functions of the telescopic frame 33 are precisely matched with the position of the mounting cavity 211, assisting the first side mechanism 1 and the second side mechanism 3 in completing the module insertion operation of mounting cavities 211 at different heights, avoiding insertion deviations or operational inconveniences caused by differences in the height of the mounting cavities 211. The telescopic frame 33, as an auxiliary support component, can be height-adjusted under the drive of the lifting frame 32, and simultaneously, in conjunction with the translation of the chassis 31, facilitates the auxiliary assembly tasks of different mounting cavities 211.

[0049] The module boxing equipment also includes a box conveyor line 2, which is used to realize the continuous conveying of the box 21. The empty box 21 to be assembled is conveyed to the preset station of the box 21 support mechanism. After all the mounting cavities 211 of the box 21 have been completed and the modules are inserted, the assembled box 21 is conveyed to the next process (such as electrical connection and sealing test), forming an integrated production process of "box 21 conveying - module boxing - finished product output", which further improves the level of production automation and reduces manual intervention.

[0050] This application also provides a module loading method for the module loading device provided in this application, including the following steps: Step S100: The first side mechanism 1 grabs one end of the battery module 5 and moves the battery module 5 to one side opening of the mounting cavity 211 on the housing 21. This step is the initial preparation stage for module loading into the box. It mainly involves gripping, calibrating the attitude of the battery module 5, and aligning it for transport. The entire process relies on the coordinated operation of the robotic arm 11 of the first side mechanism 1, the module fixture 12 (outer frame 121, movable frame 122, module support 123, module leveling part 124), the module transport line 4, and the pallet 41. The specific operation process is as follows: Preparation before picking: After the module transport line 4 delivers the tray 41 carrying the battery module 5 to the preset picking station, the transport line stops running, and the tray 41 and battery module 5 remain stationary. At this time, the battery module 5 is supported on the support body 411 in the middle of the tray 41, and is suspended on both sides along the width direction of the module transport line 4, leaving sufficient space for the outer frame 121 to be fitted.

[0051] Outer frame 121 fitting and module gripping: The robotic arm 11 of the first side mechanism 1 is activated, moving the outer frame 121 of the module fixture 12 to the material handling station. The vision positioning system 1218 precisely adjusts the posture of the outer frame 121 so that the open end of the outer frame 121 faces the battery module 5 and the two rows of support rollers 1213 at the bottom of the outer frame 121 are aligned with the suspended area at the bottom of the battery module 5. Then the robotic arm 11 controls the outer frame 121 to move slowly in the horizontal direction. Utilizing the suspended structure on both sides of the battery module 5, the outer frame 121 is gradually fitted into the battery module 5 from one side. At this time, the support rollers 1213 at the bottom of the outer frame 121 precisely support the two sides of the bottom of the battery module 5, replacing the support body 411 of the tray 41 to achieve stable support. Module Positioning and Leveling: After the outer frame 121 is installed, the second drive mechanism 1214 is activated, and the two cylinders extend synchronously, pushing the roller frames of the two side roller assemblies 1215 to slide along the slide rail into the receiving cavity, causing the side rollers to fit tightly against both sides of the battery module 5, thereby achieving clamping and limiting of the battery module 5. At the same time, the first pin 1232 of the module support part 123 is inserted into the first hole 511 of the end plate 51 of the battery module 5, and the first stop 1231 fits tightly against the end plate 51, completing the initial positioning and support of one end of the battery module 5. Subsequently, the module leveling part 124 is activated, and according to the real-time detected module posture, the height of the end of the battery module 5 is adjusted through the lifting mechanism to ensure that the battery module 5 is in a horizontal posture (leveling accuracy reaches ±0.05mm), eliminating the risk of tilting and laying the foundation for subsequent placement in the box. This process is completely matched with the functions of the module support part 123 and the module leveling part 124 mentioned above. Module Transfer and Alignment: After the module is grasped, positioned, and leveled, the robotic arm 11, based on the preset program and coordinate information fed back by the vision positioning system 1218, drives the module fixture 12 and the grasped battery module 5 to move precisely along three-dimensional space, ultimately transferring the battery module 5 to the vicinity of the box 21 fixed on the box 21 support mechanism. This ensures that the front end of the battery module 5 (the end closer to the box entry direction) is aligned with one side opening of the target mounting cavity 211 of the box 21, and the center of the battery module 5 is aligned with the center of the mounting cavity 211, ensuring accurate subsequent box entry alignment. In this step, part of the battery module 5 extends out of the outer frame 121, and the robotic arm 11 can adjust the position of the outer frame 121 so that the end of the battery module 5 extending out of the outer frame 121 is located inside the mounting cavity 211.

[0052] In step S200, the second side mechanism 3 controls the telescopic frame 33 to extend into the mounting cavity 211 from the other side opening of the mounting cavity 211 and support it at the other end of the battery module 5. The core of this step is to provide auxiliary support for the other end of the battery module 5. Through the cooperation of the second side mechanism 3 and the first side mechanism 1, excessive force on one end of the battery module 5 can be prevented from causing tilting or deformation, thus ensuring smooth placement into the box later. The specific process includes the following: Telescopic frame 33 position adjustment: According to the number of columns and height (number of layers) of the target mounting cavity 211, the frame 31 moves smoothly along the frame guide rail 6 under the drive of the servo motor, driving the lifting frame 32 and telescopic frame 33 to move synchronously to the corresponding position of the target column mounting cavity 211; then the lifting frame 32 is started (using a hydraulic lifting mechanism or a screw lifting mechanism) to precisely adjust the height of the telescopic frame 33 so that the height of the telescopic frame 33 matches the height of the mounting cavity 211 corresponding to the battery module 5, ensuring that the telescopic frame 33 can smoothly extend into the mounting cavity 211 and accurately dock with the other end of the battery module 5.

[0053] Telescopic frame 33 extension and support: After the position adjustment is completed, the second side mechanism 3 controls the telescopic frame 33 to slowly extend into the installation cavity 211 from the other side opening of the installation cavity 211 (the side opening away from the first side mechanism 1) until the end of the telescopic frame 33 reaches the end of the installation cavity 211 close to the first side mechanism 1, and the end of the telescopic frame 33 can be inserted into the first hole 511 on the corresponding side end plate 51 of the battery module 5, so as to realize the positioning and support of the other end of the battery module 5, and at the same time assist in calibrating the module posture, ensuring that the two ends of the battery module 5 are at the same height and the whole remains horizontal, forming a double-sided cooperation with the support of the first side mechanism 1, and avoiding tilting or displacement of the module during subsequent movement.

[0054] In step S300, the first side mechanism 1 controls the movable frame 122 to move the battery module 5 into the mounting cavity 211, and the telescopic frame 33 of the second side mechanism 3 moves backward synchronously. This step is the core execution stage for inserting battery module 5 into the housing. Through the synchronized action of the first side mechanism 1 and the second side mechanism 3, the battery module 5 is smoothly pushed into the mounting cavity 211, avoiding module jamming and scratches throughout the process. The specific process includes the following: Synchronous Action Activation: The first side mechanism 1 and the second side mechanism 3 are activated synchronously to achieve coordinated action. Specifically, the first drive mechanism 1217 of the first side mechanism 1 is activated, driving the movable frame 122 to move smoothly along the length of the outer frame 121 (towards the mounting cavity 211 of the housing 21). The movable frame 122 drives the clamped and supported battery module 5 to slowly move into the mounting cavity 211. At the same time, the telescopic frame 33 of the second side mechanism 3 moves backward synchronously (away from the opening of the mounting cavity 211), maintaining the same speed as the movable frame 122. This ensures that the telescopic frame 33 always supports the other end of the battery module 5 and does not undergo relative displacement with the battery module 5, thus avoiding uneven force on the front end of the module and causing tilting.

[0055] Protection and calibration during installation: During the process of pushing the battery module 5 into the mounting cavity 211, the support roller 1213 and the side roller assembly 1215 at the bottom of the outer frame 121 continuously function. The support roller 1213 rotates synchronously with the movement of the battery module 5, converting sliding friction into rolling friction, reducing movement resistance, and preventing scratches on the bottom of the battery module 5. The side roller assembly 1215 can release the sides of the battery module 5, ensuring that the battery module 5 moves smoothly along the axis of the mounting cavity 211. At the same time, the module leveling unit 124 monitors the posture of the battery module 5 in real time. If the module tilts slightly due to friction on the inner wall of the mounting cavity 211 or other factors, the lifting mechanism of the leveling unit will make timely fine adjustments to ensure that the module is always parallel to the end face of the mounting cavity 211, avoiding jamming during installation.

[0056] Movement confirmation: The movable frame 122 continues to move the battery module 5 into the mounting cavity 211 until the front end of the battery module 5 reaches the preset position of the mounting cavity 211 (the end near the other side opening of the mounting cavity 211). At this time, most of the battery module 5 has entered the mounting cavity 211, with only a small portion of the rear end still located in the receiving cavity of the outer frame 121. The equipment's sensors (such as the vision positioning system 1218 located on the outer frame 121) detect the movement stroke of the movable frame 122. After confirming that the battery module 5 has moved into place, the first side mechanism 1 and the second side mechanism 3 stop moving synchronously, preparing to proceed to the next step.

[0057] In step S400, the first side mechanism and the second side mechanism move down simultaneously, unloading the battery module 5 onto the bottom wall of the mounting cavity 211, and both the first side mechanism 1 and the second side mechanism 3 move out of the housing 21.

[0058] This step is the final stage of module placement, and its core function is to unload battery module 5 and reset equipment components, ensuring that the module is stably placed in the mounting cavity 211 and that the equipment components do not interfere with subsequent processes. The specific operation process is as follows: Synchronous Lowering and Unloading: After the battery module 5 is moved into place, the robotic arm 11 of the first side mechanism 1 and the lifting frame 32 of the second side mechanism 3 start synchronously and slowly move downwards, so that the bottom of the battery module 5 gradually fits against the bottom wall of the mounting cavity 211. During the lowering process, the battery module 5 is kept in a horizontal position to avoid hard contact between the bottom of the module and the bottom wall of the mounting cavity 211, which could cause scratches. At the same time, it is ensured that the bottom of the module fits tightly against the bottom wall of the mounting cavity 211, laying the foundation for subsequent fixing. When the battery module 5 is completely unloaded and stably placed on the bottom wall of the mounting cavity 211, the first side mechanism 1 and the second side mechanism 3 stop moving downwards. It should be noted that before the battery module 5 contacts the bottom wall of the mounting cavity 211, the lifting mechanism needs to be raised first so that the second pin 1242 disengages from the water-cooling plate 52.

[0059] Mechanism unlocking and separation: After unloading, both the first side mechanism 1 and the second side mechanism 3 are detached from the battery module 5, releasing the support on the end of the battery module 5.

[0060] Subsequent preparation: If there are other columns or other heights of mounting cavities 211 in the housing 21 that need to be equipped with battery modules 5, the equipment repeats the above steps S100 to S400 to complete the installation of all battery modules 5 in sequence; if all mounting cavities 211 in the current housing 21 are assembled, the housing conveyor line 2 starts and transports the assembled housing 21 to the next process, waiting to receive the next empty housing 21 to be assembled, forming a complete integrated production process.
