Technical Field

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

[0002] Module loading is a critical process in battery pack assembly lines, involving the precise gripping, positioning, and placement of battery modules into the enclosure. Traditionally, gantry-type transfer mechanisms are commonly used, performing module handling, positioning, and cleaning operations between multiple discrete workstations. However, with the increasing demands for production cycle time, space utilization, and production line flexibility from the new energy vehicle and energy storage industries, the gantry structure, due to its inherent limitations, is gradually becoming insufficient to meet the needs of efficient, flexible, and compact production.

The pickup component includes a base, a first adsorption member, and at least one second adsorption member. The first adsorption member is located at the center of the base, and the second adsorption member is movably connected to the base and located on one side of the first adsorption member. The second adsorption member further includes a first driving member, which is used to drive the second adsorption member to move up and down to approach or move away from the surface of the battery module.

[0009] In the module loading device described above, preferably, the gripping mechanism further includes a clamping assembly for clamping the battery module. The clamping assembly includes a second driving member, a clamping member, and a first guide member. The first guide members are symmetrically arranged on both sides of the frame, and the clamping members are symmetrically arranged between the two first guide members and are slidably connected to the first guide members. The second driving member is used to drive the two clamping members to move towards or away from each other on the first guide members.

[0010] In the module loading device described above, preferably, the gripping mechanism further includes at least one anti-detachment component. The anti-detachment component includes a lifting member and a supporting member. The lifting member is used to drive the supporting member to move up and down relative to the frame. The supporting member includes a supporting plate, a second guide member, and a third driving member. The second guide member is arranged at the output end of the lifting member along a lifting direction perpendicular to the lifting member. The supporting plate is slidably connected to the second guide member. The third driving member is used to drive the supporting plate to move on the second guide member to approach or move away from the bottom of the battery module.

[0011] In the module loading device described above, preferably, the lifting component includes a fixed plate, a movable plate, a third guide component, and a fourth driving component. The fixed plate is fixed to the frame, the third guide component is symmetrically disposed on the fixed plate, the movable plate is slidably connected to the third guide component, and the fourth driving component drives the movable plate to move up and down relative to the fixed plate.

[0012] In the module loading device described above, preferably, the pressing assembly includes a fifth driving component, a reducer, and a lead screw lifting component.

The battery module is transferred to the cleaning mechanism for cleaning the bottom of the battery module. After cleaning, the battery module is transferred to the housing support mechanism, the mark points on the housing are identified, and the battery module is positioned above the corresponding placement position inside the housing. The battery module is pressed into the corresponding position inside the box from above by the pressing component, and the compressed state of the battery module is maintained during the box insertion process; Repeat the above steps until all battery modules are successfully placed into the box in sequence. Compared with existing technologies, this invention uses a multi-axis robot and a ground rail as a transfer mechanism, which allows each workstation to be compactly arranged along the ground rail direction. This effectively solves the problem of large footprint of traditional gantry structures, enabling the equipment to quickly switch between workstations. Compared with traditional gantry structures, it significantly improves production cycle and efficiency, while also having good flexible expansion capabilities, which can adapt to the mixed production needs of multi-specification products.

[0016] By integrating the cleaning mechanism into the robot's transport path, there is no need to set up an additional independent cleaning station, which further simplifies the production line structure; The gripping mechanism integrates a picking component and a pressing component. After the module is accurately positioned on the top of the box, it is pressed into the box, avoiding the bump damage caused by positioning deviation during the traditional rigid clamping process. Together with the clamping component that maintains the pressure of the module during the transfer process, it effectively prevents the module from loosening due to stress release at the moment of entering the box, significantly improving the assembly quality and yield of the product.

[0019] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] This embodiment provides a module loading device, including a module carrying mechanism 10, a box carrying mechanism 20, a transfer mechanism 30, a gripping mechanism 40, and a cleaning mechanism 50, wherein: The module carrying mechanism 10 is used to position and carry the battery modules. In this embodiment, the module carrying mechanism 10 has two module workstations, which can load two battery modules at a time. It should be noted that the module carrying mechanism 10 in this embodiment adopts an existing carrying mechanism with module pressure holding and module pressure releasing functions. The AGV transfer trolley transfers the pallet containing the battery modules to the module workstation. The module carrying mechanism 10 holds the pressure of the battery modules to be placed in the box, and releases the pressure when the transfer mechanism 30 grabs them. This module carrying mechanism 10 with pressure holding and pressure releasing functions is existing technology, and its specific structure and working principle will not be described in detail here.

[0021] The box-supporting mechanism 20 is used to position and support the box to be assembled. In this embodiment, at least one box can be placed on the box-supporting mechanism 20, and the box-supporting mechanism 20 is provided with a positioning structure for positioning the box and ensuring that the box remains stable during the box insertion process.

[0022] Traditional gantry-type transfer mechanisms require a large planar movement space for each workstation, resulting in a large overall lateral span, large equipment footprint, and poor production line compactness. In this embodiment, the transfer mechanism 30 includes a multi-axis robot 31 and a ground rail 32 that drives the multi-axis robot 31. The extension path of the ground rail 32 covers the area where the module support mechanism 10 and the box support mechanism 20 are located. In this embodiment, the multi-axis robot 31 can be a six-axis articulated robot with six degrees of freedom, allowing for flexible adjustment of its end effector posture. The ground rail 32 extends horizontally, and the multi-axis robot 31 is movably mounted on it and can reciprocate along it. The ground rail 32 forms the robot's seventh axis, increasing its range of motion. Each workstation can be compactly arranged along the ground rail 32. The increased range of motion of the multi-axis robot 31 via the ground rail 32 enhances equipment flexibility and effectively reduces the equipment's footprint, resulting in a more compact production line layout.

[0023] In this embodiment, the gripping mechanism 40 is mounted on the end of the multi-axis robot 31. The gripping mechanism 40 includes a frame 41, a picking component 42, and a pressing component 45. The picking component 42 is used to pick up the battery module, and the pressing component 45 is used to press the battery module into the box when it is positioned at a preset position on the top of the box. After the battery module is accurately positioned at the preset position on the top of the box, it is smoothly pressed into the box by the pressing component 45. The action logic of positioning first and then pressing avoids the risk of bumps during the box insertion process, improving the assembly quality and yield of the product.

[0024] The cleaning mechanism 50 is located on one side of the ground rail 32, between the module carrying mechanism 10 and the housing carrying mechanism 20, and is used to clean the bottom of the battery module gripped by the gripping mechanism 40. In this embodiment, the cleaning mechanism 50 can be a plasma cleaner, which can effectively remove dust, oil and other contaminants from the bottom of the module, improving the reliability of subsequent assembly. Plasma cleaners are existing technology, and their structure and working principle are well known to those skilled in the art, and will not be described in detail here. During the process of the robot moving the battery module from the module side to the housing side, it can pass through the cleaning mechanism 50 to complete the bottom cleaning, without adding extra workstations and transfer time, realizing the integrated design of functions and simplifying the process flow.

[0025] Furthermore, both the module carrying mechanism 10 and the box carrying mechanism 20 are configured in pairs and are arranged symmetrically on both sides of the ground rail 32 along its extension direction. In this embodiment, multiple workstations can be loaded into boxes through a single transfer mechanism 30. While a module is being loaded into a box on one side, a module can be loaded or a box can be transferred on the other side. The alternating operation of the workstations on the left and right sides reduces the robot's waiting time, significantly improves equipment utilization, and optimizes the overall production cycle.

[0026] In some embodiments of this application, the pickup component 42 is connected to the drive end of the pressing component 45. The pickup component 42 includes a base 421, a first adsorption member 422, and at least one second adsorption member 423. The first adsorption member 422 is located at the center of the base 421. The second adsorption member 423 is movably connected to the base 421 and is located on one side of the first adsorption member 422. The second adsorption member 423 also includes a first driving member 424, which is used to drive the second adsorption member 423 to move up and down to get closer to or away from the surface of the battery module. In this embodiment, the first adsorption member 422 is fixed at the center of the base 421 to provide the main adsorption force. For battery modules of different sizes, the second adsorption member 423 can be driven to descend by the first driving member 424 to form an auxiliary support. The first driving member 424 can be a cylinder. The fixed end of the cylinder is connected to the base 421, and the output end is equipped with the second adsorption member 423. Furthermore, multiple mounting holes 425 can be provided on the base 421 to change the mounting position of the cylinder and achieve the adaptation of more battery module sizes.

[0027] Furthermore, the gripping mechanism 40 also includes a clamping assembly 43 for clamping the battery module. The clamping assembly 43 includes a second driving member 431, a clamping member 432, and a first guide member 433. The first guide members 433 are symmetrically arranged on both sides of the frame 41, and the clamping members 432 are symmetrically arranged between the two first guide members 433, and the clamping members 432 are slidably connected to the first guide members 433. The second driving member 431 is used to drive the two clamping members 432 to move towards or away from each other on the first guide members 433. In this embodiment, the clamping member 432 is a gripper, the first guide member 433 is a slide rail, and the second driving member 431 is a servo motor to drive the two clamping members 432 to move. The battery module is in a pressure-holding state on the tray. When the gripping mechanism 40 removes it from the tray, the battery module will release pressure instantly. The clamping component 43 clamps the battery module on both sides before it is removed from the tray, maintaining pressure throughout the transfer process and effectively preventing the cells from loosening or bursting. The pickup component 42 grips the top of the module using suction, while the clamping component 43 provides mechanical clamping force from both sides, significantly improving gripping safety.

[0028] Furthermore, the gripping mechanism 40 also includes at least one anti-detachment component 44, used to lift the battery module from the bottom during gripping and transfer, preventing the battery module from falling due to adsorption or clamping failure, and improving the safety of equipment operation. In this embodiment, two anti-detachment components 44 are provided, symmetrically arranged on both sides of the frame 41, and perpendicular to the clamping component 43. The anti-detachment component 44 includes a lifting member and a supporting member. The lifting member is used to drive the supporting member to rise and fall relative to the frame 41 to reach a preset position at the bottom of the module, and the supporting member is used to support the bottom of the battery module.

[0029] Specifically, the support component includes a support plate 441, a second guide 442, and a third drive 443. The second guide 442 is arranged at the output end of the lifting component along a lifting direction perpendicular to the lifting component. The support plate 441 is slidably connected to the second guide 442. The third drive 443 is used to drive the support plate 441 to move on the second guide 442 to approach or move away from the bottom of the battery module. The lifting component includes a fixed plate 444, a movable plate 445, a third guide 446, and a fourth drive 447. The fixed plate 444 is fixed to the frame 41. The third guide 446 is symmetrically arranged on the fixed plate 444. The movable plate 445 is slidably connected to the third guide 446. The fourth drive 447 drives the movable plate 445 to move up and down relative to the fixed plate 444. The third drive component 443 and the fourth drive component 447 can be cylinders, the second guide component 442 and the third guide component 446 can be slide rails, the fixed end of the fourth drive component 447 is set on the frame 41, and the output end is connected to the movable plate 445. The second guide component 442 is symmetrically installed at the bottom of the movable plate 445. The fixed end of the third drive component 443 is fixed to the movable plate 445, and the output end is connected to the support plate.

[0030] During operation, after the lifting component drives the support component to descend to a predetermined height, the support component extends horizontally relative to the lifting component under the drive of the third drive component 443, allowing the support plate 441 to insert below the bottom of the battery module, providing support for the module. During subsequent transfer, cleaning, and waiting processes, the support plate 441 remains extended, providing support to the bottom of the module. Even in the event of adsorption failure, clamping loosening, or sudden power outage, the battery module will be caught by the support plate 441 if it falls, effectively preventing the risk of detachment. When the module is moved above the housing to prepare for placement, the support component retracts actively under the drive of the third drive component 443 to avoid interference with the housing, and then the lifting component drives the support component to rise and reset.

[0031] Furthermore, a limiter 448 is provided on the fixed plate 444, and a mating block 449 that cooperates with the limiter 448 is provided on the movable plate 445. By adjusting the relative distance between the limiter 448 and the mating block 449, the descent stroke of the movable plate 445 relative to the fixed plate 444 can be limited, thereby adjusting the working stroke of the fourth drive component 447. When handling battery modules of different heights, the operator can adjust the position of the limiter 448 to lower the support component to a height that matches the bottom of the module. This allows for quick adjustment without replacing any parts, enhancing the equipment's adaptability to different product specifications.

[0032] In this embodiment, the pressing component 45 includes a fifth driving member 451, a reducer 452, and a lead screw lifting member 453. The lead screw lifting member 453 is mounted on the frame 41, and its output end is connected to the pickup component 42. The output end of the fifth driving member 451 is connected to the reducer 452, and the reducer 452 is connected to the input end of the lead screw lifting member 453. The lead screw lifting member 453 adopts a ball screw lifting mechanism known in the art, and its specific internal structure and working principle are well known to those skilled in the art and will not be described in detail here. The lead screw lifting member 453 has four lead screws arranged in a rectangular array. Each lead screw is linked through a synchronous belt or gear transmission mechanism. The output ends of the four lead screws are all connected to the base 421 of the pickup component 42 or the mounting bracket of the first adsorption member 422. The fifth driving member 451 is a servo motor, which drives the four lead screws to achieve synchronous lifting motion through the reducer. When the battery module reaches the preset position at the top of the housing, the pressing component 45 applies downward pressure to the battery module through the picking component 42, causing it to be smoothly pressed into the housing. Of course, in other embodiments, a gear and rack lifting component or the like can also be used, and this is not limited here.

[0033] In this embodiment, the gripping mechanism 40 further includes a vision detection component 46, which is located at the front end of the frame 41 and is used to detect mark points on the housing. The vision detection component 46 includes an industrial camera 461 and a light source 462. When the battery module is moved above the housing, it identifies the preset mark points on the housing and calculates the deviation between the module and the target position in real time, providing guidance for the robot's posture adjustment.

[0034] Furthermore, a laser rangefinder 47 is also provided on the frame 41 to detect the distance between the gripping mechanism 40 and the surface of the target object. Specifically, the laser rangefinder 47 is installed at the front end or side of the frame 41, with its detection optical axis pointing downwards. It can measure the distance between the sensor and the target object in real time, such as the top of the battery module, the bottom or upper edge of the box, and the cleaning mechanism 50. The laser rangefinder 47 provides real-time, high-precision distance feedback, enabling precise control of the descent stroke of the gripping mechanism 40 and the pressing depth of the pressing component 45. When changing products, it can measure the height and depth information of different modules and boxes in real time, allowing the equipment to adapt to the production needs of various product specifications, improving the accuracy of box insertion and production efficiency.

[0035] This embodiment also provides a module loading method, which is based on the aforementioned module loading device. Through systematic process control, it automates the entire process of battery module loading, from picking and cleaning to loading. It includes the following steps: S100: Obtain information on multiple battery modules to be placed in the box and information on the box to be assembled; S200. Based on the information obtained, determine the preset placement order and corresponding position of each battery module in the housing; S300, the control transfer mechanism 30 transfers the battery modules from the module carrying mechanism 10 in a preset placement order, and maintains the pressure on the battery modules through the gripping mechanism 40 during the transfer process. S400: Transfer the battery module to the cleaning mechanism 50 and clean its bottom. S500: Transfer the cleaned battery module to the housing support mechanism 20, identify the mark points on the housing, and position the battery module above the corresponding placement position inside the housing. S600: Apply downward pressure to the battery module, pressing it into the corresponding position inside the box from above, and maintain the compressed state of the battery module during the insertion process. S700. Repeat the above steps until all battery modules are placed into the box in sequence.

[0036] Specifically, in step S100, the system can read the unique code of each battery module on the module carrier mechanism 10 through a barcode scanner or other identification device to obtain information such as the model, size, and compression status requirements of each module. The system can also read the code information of the box to be assembled on the box carrier mechanism 20 to obtain the box model, internal structural layout, and module placement information.

[0037] In step S200, taking the case design to accommodate four battery modules as an example, the boxes correspond to positions 1 to 4 respectively. Based on the above information, the system automatically plans the preset placement order of each module, such as placing them sequentially from position 1 to position 4, and the target position corresponding to each module.

[0038] In step S300, the picking component 42 picks up the battery module from the top, while the clamping component 43 clamps the battery module from both sides. After the module support mechanism 10 releases pressure, the multi-axis robot 31 can move the battery module off the tray. During the gripping process, the laser rangefinder 47 detects the module height in real time to ensure that the gripping mechanism 40 accurately reaches the gripping position and avoids excessive descent causing a collision. After the gripping is completed, the gripping mechanism 40 immediately activates the anti-detachment component 44. The lifting component drives the support component to descend to the bottom of the battery module, and the support plate 441 extends below the bottom of the module to support it. At the same time, the clamping component 43 maintains the clamping force on the module, keeping the module in the pressure-holding state required for its assembly.

[0039] In step S400, the multi-axis robot 31 carries the module and moves along the ground rail 32 toward the housing support mechanism 20. When it passes the cleaning mechanism 50, the robot pauses or passes slowly, and the cleaning mechanism 50 starts to clean the bottom surface of the battery module. After cleaning, the robot continues to move toward the housing.

[0040] In step S500, the multi-axis robot 31 moves the cleaned battery module above the housing support mechanism 20. The vision inspection component 46 identifies the Mark points on the housing to determine the target position of the current module. During this process, the laser range sensor 47 acquires the height information of reaching the preset height of the housing.

[0041] In step S600, when the battery module reaches a certain height at the top of the housing, that is, close to the housing but not yet inside the housing, the anti-detachment component 44 retracts to make way, avoiding interference between the support plate 441 and the housing. The battery module continues to descend. When the bottom of the clamping member 432 is 10cm away from the top of the edge of the housing, the battery module has partially entered the housing. At this time, the transfer mechanism 30 is suspended, and the pressing component 45 applies controllable downward pressure to smoothly press the battery module into the corresponding slot in the housing. Throughout the pressing process, the clamping component 43 maintains a clamping force on the module to prevent the module from loosening or bursting due to stress release at the moment of entering the box. After the battery module is fully inserted into the box, the clamping component 43 is removed. It should be noted that although the battery module rubs against the clamping component 432 during the pressing process of the pressing component 45, the clamping component 432 only maintains the pressure state of the battery module and will not cause damage to the surface of the battery module. Of course, corresponding protective structures can also be made on the clamping surface of the clamping component 432 to protect the battery module.

[0042] In step S700, after a module is placed into the box, the gripping mechanism 40 releases the module, and the multi-axis robot 31 returns to the module carrying mechanism 10 to grip the next module to be placed into the box, such as module No. 2. Steps S200 to S600 are repeated until all battery modules are placed into the box in the preset order, that is, modules No. 1 to No. 4 are all completed.

[0043] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
