Description

Technical Field

[0001] This invention relates to the field of packaging technology, specifically to a battery pack packaging machine. Background Technology

[0002] In the production and assembly process of power batteries and energy storage batteries, the encapsulation process after the battery pack is installed in the casing is a key step to ensure the stability and safety of the battery structure. It mainly includes two core processes: foam application and capping. The foam application process involves attaching cushioning foam to the inner wall of the battery pack casing or in the gap between the battery pack and the casing. The elastic deformation of the foam absorbs vibration and mitigates impact, avoiding the risk of wear or short circuits caused by direct rigid contact between the battery pack and the casing. The capping process requires precisely fastening or welding the top cover of the casing to the opening of the casing, thereby achieving a sealed protection for the battery pack and preventing external dust and moisture from entering and affecting battery performance.

[0003] Currently, these two processes are mainly completed in steps using independent equipment: after the battery pack is installed in the casing, foam is first applied using specialized foam-applying equipment, and then the top cover is sealed using specialized sealing equipment. This step-by-step operation mode has revealed significant drawbacks in actual production: on the one hand, the equipment changeover and battery pack transfer between processes are time-consuming, resulting in low overall processing efficiency and difficulty in meeting the cycle time requirements of large-scale production; on the other hand, the two positioning operations are prone to cumulative errors, which can lead to problems such as foam application misalignment and top cover misalignment. This not only affects the cushioning and sealing performance but may also cause uneven stress on the internal structure of the battery pack due to excessive deformation of the foam caused by the top cover pressing on it, posing a safety hazard.

[0004] Furthermore, the separate configuration of independent equipment requires more production space, increases equipment procurement and maintenance costs, and manual handling during transfer or assisted positioning may further amplify alignment errors due to improper operation. Therefore, the lack of integrated equipment that can simultaneously integrate foam application and capping functions in the current technology has become a key bottleneck restricting the efficiency improvement and quality control of the battery pack packaging process. There is an urgent need to achieve collaborative operation of the two processes through equipment structure innovation to solve problems such as low efficiency and large alignment errors.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0022] Example:

[0023] See Figure 1 and Figure 2As shown, this embodiment provides a battery pack packaging machine, which includes a substrate 100 and a positioning and detection mechanism 200, at least one foam transfer mechanism 300, and at least one top cover mechanism 400 connected to the substrate 100. The substrate 100 is externally connected to a mobile device. The foam transfer mechanism 300 includes an adsorption component 330, which is slidably connected to the substrate 100 along a first direction X and has multiple adsorption stations 3321. The top cover mechanism 400 includes a cover limiting component 440 and a clamping component 450. The clamping component 450 includes at least two relatively movable clamping plates 452 to clamp the top cover to be assembled. The cover limiting component 440 includes a pressing block 443, which is disposed between at least two clamping plates 452 and can move up and down along the first direction X. The side of the pressing block 443 facing the top cover to be assembled is configured as a planar structure.

[0024] The battery pack packaging machine described in this embodiment uses a positioning and detection mechanism 200 to navigate and locate the foam to be loaded. Then, a foam transfer mechanism 300 picks up the foam to be assembled and places it onto the corresponding battery. Simultaneously, the top cover mechanism 400 moves the top cover of the battery pack housing. After the foam is assembled, the battery pack can be packaged. During this process, the pressure cap limiting component 440 can level the top cover to be packaged to ensure its assembly accuracy and can also press the packaged top cover to ensure the stability of the packaging structure. The cooperation between these structures not only improves the processing efficiency between each cycle but also improves the packaging quality. Compared with current conventional battery pack packaging technologies, this application has advantages such as high automation, high processing accuracy, significantly improved efficiency and quality, strong controllability, and wide applicability, and has broad application prospects in the industry.

[0025] It should be noted that, for ease of description, in this embodiment, the height direction of the battery pack packaging machine is defined as the first direction, the length direction of the battery pack packaging machine is defined as the second direction, and the width direction of the battery pack packaging machine is defined as the third direction. The first direction, the second direction, and the third direction are arranged perpendicular to each other in pairs, and the second direction and the third direction are located in the same plane.

[0026] Specifically, see Figure 3As shown, in this embodiment, the substrate 100 serves as the basic support structure of the equipment and is connected to an external mobile device, which is used to move the entire packaging machine to different workstations, improving operational flexibility. In different implementations, the external mobile device can be configured as a robotic arm, mobile robot, or crane, etc., and this invention does not impose specific limitations on this. Specifically, in this embodiment, the substrate 100 extends along the second direction Y, and is sequentially provided with a first connecting part 110, a second connecting part 120, an external connecting part 130, and a third connecting part 140 in its length direction. The positioning detection mechanism 200 is connected to the first connecting part 110, the foam transfer mechanism 300 is connected to the second connecting part 120, the external connecting part 130 is connected to the external mobile device, the top cover mechanism 400 is connected to the third connecting part 140, and the clamping plate 452 opens and closes along the third direction Z. The extension length of the third connecting part 140 in the third direction Z is greater than the extension lengths of the first connecting part 110, the second connecting part 120, and the external connecting part 130 in the third direction Z. Based on the above structural design, the linearly arranged connecting parts make the overall structure of the equipment compact. When used with external mobile equipment, it can efficiently complete multi-station switching. The design of the third connecting part 140 provides more operating space for the upper cover mechanism 400 and meets the stroke required for the opening and closing of the clamping plate 452.

[0027] In this embodiment, the positioning detection mechanism 200 further includes a fixing plate 210, a protective box 220, a camera 230, and a light source 240. The fixing plate 210 is connected to the base plate 100, and the protective box 220 and the light source 240 are respectively connected to the fixing plate 210. The protective box 220 has a shooting port communicating with the outside on one side, and the light source 240 is correspondingly positioned at the shooting port. The camera 230 is disposed inside the protective box 220, with its working end facing the shooting port. The fixing plate 210 serves as the basic supporting component of the positioning detection mechanism 200, providing a stable installation reference for each component to ensure the positional accuracy of shooting and illumination. The protective box 220 protects the internal camera 230 from external dust, moisture, or mechanical impact, providing a stable working environment, especially for high-precision detection equipment. Furthermore, the bottom of the protective box 220 has a shooting port, thereby establishing an optical path between the camera and the external detection area, while also reducing external stray light entering the box and interfering with imaging. The camera 230 is installed inside the protective housing 220, with its working lens facing the imaging port to acquire image information of the battery pack under test. The light source 240 is positioned corresponding to the imaging port to provide uniform and stable illumination to the imaging area.

[0028] Furthermore, the camera 230 internally includes a positioning and addressing module and a quality inspection module. The battery pack packaging machine also includes a control mechanism. The positioning and addressing module and the quality inspection module are respectively connected to the input end of the control mechanism, and the foam transfer mechanism 300 and the top cover mechanism 400 are respectively connected to the output end of the control mechanism. The positioning and addressing module can position and navigate the foam before it moves, and the quality inspection module can inspect the assembly quality after the foam is assembled. Specifically, the positioning and addressing module is activated before the foam transfer mechanism 300 grasps and moves the foam. It uses image recognition technology to accurately locate the initial position of the foam, generates coordinate information, and transmits it to the control mechanism, providing navigation for the foam transfer mechanism 300. This ensures that the adsorption component 330 can accurately grasp the foam, thereby avoiding grasping failures due to initial foam position deviations. This is particularly suitable for scenarios with slight positional shifts that may occur during batch feeding. The quality inspection module is activated after the foam is assembled onto the battery pack. It uses image analysis to determine the assembly quality of the foam, detecting defects such as misalignment, omissions, and warping, and feeds the results back to the control mechanism. This achieves real-time assembly quality monitoring, preventing defective products from flowing into the next process and reducing subsequent rework costs. The control mechanism receives navigation data from the positioning and addressing module and the inspection results from the quality inspection module at its input end; at its output end, it controls the actions of the foam transfer mechanism 300 and the top cover mechanism 400 based on the input signals. During actual production, operators can adjust the above structures in real time through the control mechanism, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thus increasing the automation level of the equipment.

[0029] See Figure 4 and Figure 5As shown, the foam transfer mechanism 300 in this embodiment is used to grasp and transfer foam. The adsorption component 330 can be raised, lowered, moved, and slid to simultaneously grasp foam groups through multiple adsorption stations 3321, thereby improving efficiency. Further, the foam transfer mechanism 300 in this embodiment also includes a first mounting frame 310, a guide rod 320, and a first lifting driver 340. The first mounting frame 310 is connected to the base plate 100. The guide rod 320 extends along a first direction X, with one end connected to the adsorption component 330 and the other end passing through and connected to the first mounting frame 310. The first lifting driver 340 is disposed on the first mounting frame 310, and its working end is connected to the adsorption component 330 to drive the adsorption component 330 to move along the first direction X. The first mounting frame 310 serves as the basic support component of the foam transfer mechanism 300, and is fixedly connected to the second connecting part 120 of the base plate 100. It provides a stable mounting reference for components such as the guide rod 320 and the first lifting driver 340, ensuring the rigidity and operational accuracy of the entire mechanism. The guide rod 320 provides guiding constraints for the lifting and lowering movement of the adsorption component 330, ensuring it moves along a strictly linear trajectory and avoiding deviation or swaying. The first lifting driver 340 is the power source driving the movement of the adsorption component 330; in this embodiment, it is preferably a linear motor. When the foam transfer mechanism 300 receives an instruction from the control mechanism, the adsorption component 330 moves towards the foam feeding device until it grabs the foam at the adsorption station 3321, rises, moves to the target assembly position, and then descends via the first lifting driver 340 to complete the foam assembly.

[0030] Furthermore, the foam transfer mechanism 300 in this embodiment also includes a first floating component 350. The first floating component 350 is disposed between the working end of the first lifting drive 340 and the adsorption component 330. It includes a fixed block 351, a first floating guide rod 352, a first floating plate 353, a first elastic element 354, and a first pressure sensor 355. The fixed block 351 is fixedly connected to the first mounting frame 310. The first floating guide rod 352 extends along a first direction X, with one end connected to the first floating plate 353 and the other end passing through and connected to the fixed block 351. The first elastic element 354 is disposed between the first floating plate 353 and the fixed block 351. The first pressure sensor 355 is disposed between the first floating plate 353 and the adsorption component 330. The fixed block 351 is rigidly connected to the first mounting frame 310, and the first floating guide rod 352 provides guidance for the floating action.

[0031] The first elastic element 354 provides buffering and reset functions, the first floating plate 353 transmits the driving force and bears the force of the elastic element, and the first pressure sensor 355 is used to detect the pressure change between the two. Furthermore, when the adsorption assembly 330 descends to grasp the foam or assemble it onto the battery pack surface, if there is a positional deviation or height error, the first elastic element 354 will absorb the excess driving force through compression deformation, preventing the adsorption assembly 330 from rigidly impacting the foam or battery pack, thereby preventing the foam from being crushed or the battery pack casing from being damaged.

[0032] During this process, the first pressure sensor 355 can detect the pressure value between the adsorption component 330 and the floating plate in real time and transmit the signal to the control mechanism. When gripping the foam, the pressure can be used to determine whether the adsorption is in place. Similarly, when assembling the foam, the pressure is controlled within a reasonable range to avoid problems such as excessive pressure causing foam deformation or insufficient pressure causing insecure assembly. Based on the above design, the first floating component 350 realizes quantitative control of the assembly force through pressure feedback, improves the consistency of foam assembly, reduces the requirements for the accuracy of the preceding positioning, and indirectly improves the fault tolerance of the equipment.

[0033] In this embodiment, the adsorption assembly 330 includes a negative pressure box 331 and an adsorption element 332. The negative pressure box 331 is provided with a connecting nozzle 3311, which communicates with an external negative pressure generator. The negative pressure box 331 is connected to one side of the adsorption element 332, and multiple adsorption stations 3321 are arranged on the other side of the adsorption element 332. Based on this structural design, the external negative pressure generator provides a negative pressure source to the negative pressure box 331 through the connecting nozzle 3311. The negative pressure is conducted through the negative pressure box 331 to the interior of the adsorption element 332, causing the multiple adsorption stations 3321 on the other side of the adsorption element 332 to generate adsorption force. Further, in this embodiment, the multiple adsorption stations 3321 are designed as a continuous circular disc-shaped adsorption structure with the same shape as the foam assembly. In different implementations, the specific number, connection position, and arrangement of the adsorption stations 3321 can be adaptively adjusted according to actual usage requirements, and this invention does not impose specific limitations on this.

[0034] See Figure 6As shown, the top cover mechanism 400 in this embodiment is used to grasp, position, and press-fit the battery pack top cover. It includes a second mounting frame 410 and a second lifting driver 420. The second mounting frame 410 is connected to the substrate 100 and includes a first sub-frame 411 and a second sub-frame 412 arranged along a first direction X. The second lifting driver 420 is disposed on the first sub-frame 411, and its working end extends into the second sub-frame 412 and is connected to the cover limiting component 440. The cover limiting component 440 and the clamping component 450 are respectively connected to the second sub-frame 412. This structural design achieves an orderly layout of the cover limiting component 440 and the clamping component 450 through the modular disassembly of the second mounting frame 410. The first subframe 411 and the second subframe 412 are arranged vertically at intervals to form an installation reference for the upper and lower layers. This layered installation architecture simplifies the assembly process of each component and provides an independent operating space for component replacement during later maintenance, thereby enhancing the structural flexibility of the upper cover mechanism 400.

[0035] Further, see Figure 7 As shown, the clamping assembly 450 in this embodiment is used to clamp the cover to be assembled, ensuring stable transport of the cover. The clamping assembly 450 also includes a clamping driver 451, a sensing plate 453, and a clamping sensor 454. The working end of the clamping driver 451 is connected to at least two of the clamping plates 452 to drive the at least two clamping plates 452 to move relative to each other. The sensing plate 453 is connected to the clamping plates 452. The clamping sensor 454 is disposed on one side of the clamping assembly 450, and the sensing plate 453 can pass through the clamping sensor 454. The clamping driver 451 is preferably a linear double-headed cylinder, which can synchronously drive the two clamping plates 452 to move closer to or further away from each other. The detection unit consists of a sensing element 453 and a clamping sensor 454. The sensing element 453 is a thin metal sheet vertically connected to the side extension of the clamping plate 452, and its length is slightly greater than the travel of the clamping plate 452. The clamping sensor 454 is a slot-type photoelectric sensor, which is fixed on the mounting bracket of the clamping assembly 450. The center line of its detection slot coincides with the movement trajectory of the sensing element 453. When the clamping plate 452 moves relative to the clamping plate, the sensing element 453 extends into or retracts from the detection slot of the clamping sensor 454 synchronously with the clamping plate 452. When the clamping plate 452 is in the open state, the sensing element 453 is completely retracted from the detection slot, and the sensor outputs a non-clamping signal. When the clamping plate 452 closes to clamp the cover, the sensing element 453 partially or completely penetrates the detection slot, and the sensor outputs a clamping signal to indicate that the clamping action is in place.

[0036] See Figure 8As shown, the cap-limiting component 440 in this embodiment is used to limit and level the loading angle of the cap to ensure that the cap can reach the corresponding battery pack in a horizontal state. Simultaneously, it can also uniformly press the assembled cap to ensure a tight connection with the battery pack housing. Specifically, the cap-limiting component 440 in this embodiment further includes a lifting plate 441 and a drive shaft 442. The lifting plate 441 is disposed inside the second sub-frame 412, with one side connected to the working end of the second lifting driver 420 and the other side connected to the drive shaft 442. The drive shaft 442 extends along the first direction X and passes through the outside of the second sub-frame 412 to connect to the pressing block 443 and drive the pressing block 443 to move along the first direction X. This structure, through the rigid connection between the lifting plate 441 and the drive shaft 442, forms an intermediate carrier for force transmission, stably transmitting the power of the second lifting driver 420 to the pressing block 443. When the second lifting driver 420 drives the lifting plate 441 to move along the first direction X, the transmission shaft 442 synchronously drives the pressure block 443 to perform pressing or lifting actions: when pressing down, the pressure block 443 acts precisely on the preset limit position of the cover, and achieves a tight fit of the cover through the preset pressure; when lifting, the transmission shaft 442 drives the pressure block 443 to quickly detach from the cover, avoiding interference with subsequent processes.

[0037] Furthermore, the upper cover mechanism 400 also includes a second floating component 430, which is disposed between the working end of the second lifting driver 420 and the clamping component 450. The second floating component 430 includes a transmission plate 431, a second floating guide rod 432, a second floating plate 433, a second elastic element 434, and a second pressure sensor 435. The transmission plate 431 is fixed to the second mounting frame 410. The second floating guide rod 432 extends along a first direction X, with one end connected to the second floating plate 433 and the other end passing through and connected to the transmission plate 431. The second elastic element 434 is disposed between the second floating plate 433 and the transmission plate 431. The second pressure sensor 435 is disposed between the second floating plate 433 and the clamping component 450. Specifically, the second floating component 430, through a combination of elastic buffering and pressure detection, provides flexible adjustment capability for the clamping component 450, avoiding component damage caused by hard contact. The transmission plate 431 serves as a fixed reference component, rigidly connected to the second mounting frame 410 via bolts. It has guide holes adapted to the second floating guide rod 432 to ensure precise sliding of the guide rod along the first direction X. The second floating guide rod 432 serves both a guiding function and limits the lateral displacement of the floating plate. The second elastic element 434 is a cylindrical helical spring, sleeved on the outside of the floating guide rod and in a pre-compressed state, providing stable buffering force for the floating plate. When the clamping assembly 450 contacts the cover or is impacted by an external force, the second floating plate 433 moves axially along the guide rod by compressing the elastic element, converting the rigid impact into elastic potential energy and releasing it, protecting the cover surface and the clamping mechanism. The second pressure sensor 435 is installed between the second floating plate 433 and the clamping assembly 450 to detect the contact pressure value in real time. When the pressure reaches a preset threshold upper limit, the sensor feeds a signal to the controller, which then controls the second lifting drive 420 to stop operating, preventing damage from overpressure.

[0038] The specific working process and principle of the battery pack packaging machine in this embodiment are described below: First, the positioning and detection mechanism 200 can capture and locate the position of the foam to be moved and navigate it. Then, it drives the foam transfer mechanism 300 to pick up the foam and clamps the top cover through the top cover mechanism 400. Then, according to the addressing result, the foam and the top cover are moved synchronously to the top of the battery pack to be assembled, and the foam assembly and top cover pressing actions are performed in sequence. During this process, the pressing block 443 can limit the pressing angle of the top cover and press down to fix the top cover to ensure the assembly quality.

[0039] In summary, the battery pack packaging machine of this invention uses a positioning and detection mechanism 200 to locate and navigate the foam to be loaded, followed by a foam transfer mechanism 300 that picks up the foam to be assembled and places it onto the corresponding battery. Simultaneously, the top cover mechanism 400 moves the top cover of the battery pack housing. After the foam is assembled, the battery pack can be packaged. During this process, the pressure cap limiting component 440 can level the top cover to be packaged to ensure its assembly accuracy and can also press the packaged top cover to ensure the stability of the packaging structure. The cooperation between these structures not only improves the processing efficiency between each cycle but also enhances the packaging quality. Compared to current conventional battery pack packaging technologies, this application has advantages such as high automation, high processing accuracy, significantly improved efficiency and quality, strong controllability, and wide applicability, and has broad application prospects in the industry.

It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
