Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an automatic battery foam attaching device. Background Technology

[0002] In the assembly and production of products such as lithium batteries, foam with adhesive backing is often attached to specific locations on the surface to provide cushioning, insulation, or sealing. During the attachment process, operators must individually pick up foam with release paper attached, peel off the release paper from the back, align it, and then attach it to the battery surface. For double-sided attachment, the battery must be rotated 180°, and the above process repeated. This cumbersome procedure results in low production efficiency, significantly hindering the overall production line capacity. Furthermore, manual operation makes it difficult to guarantee the consistency and accuracy of the attachment position, easily leading to quality problems such as misalignment, slant placement, or air bubbles, severely impacting product yield. Simultaneously, the repetitive and labor-intensive nature of the mechanical work easily causes operator fatigue, further contributing to fluctuations in production efficiency and increased quality risks.

[0003] To overcome the drawbacks of manual operation, some automated equipment has been attempted for this process, such as using robotic arms to grasp and attach foam. However, many automated devices have limited functionality, resulting in poor surface treatment of the foam and battery, which affects the attachment effect. Furthermore, double-sided attachment requires complex flipping mechanisms or two separate processes, leading to low efficiency and poor consistency. Achieving efficient, high-precision, high-quality, and highly consistent automated attachment remains a problem that needs to be solved. Utility Model Content

In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0044] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0045] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0046] In the assembly and production of products such as lithium batteries, foam with adhesive backing is often applied to specific locations on the surface to provide cushioning, insulation, or sealing. During the application process, operators must repeatedly perform actions such as picking up materials, peeling release paper, aligning and applying the foam, and flipping the battery, resulting in low production efficiency, poor consistency in application quality, and high labor intensity. Some automated application equipment also has limited functionality, not only producing poor application results but also exhibiting complex, inefficient, and inconsistent double-sided application operations, significantly hindering the overall production line capacity. Therefore, there is an urgent need to develop automated equipment to solve these problems.

[0047] Please see Figures 1 to 5 This invention provides an automatic battery foam attaching device according to an embodiment of the present invention, comprising a frame 100, and a conveying device 200, a cleaning device 300, a positioning device 400, and an attaching device 500 mounted on the frame 100. The conveying device 200 sequentially conveys the battery to a cleaning station, a positioning station, and an attaching station 10. The cleaning device 300, the positioning device 400, and the attaching device 500 are arranged along the conveying path of the conveying device 200 and correspond to the cleaning station, the positioning station, and the attaching station 10, respectively. The two attaching devices 500 are symmetrically arranged on opposite sides of the conveying device 200, and can simultaneously attach foam to both sides of the battery. Through the above integrated layout, a fully automated process for double-sided foam bonding of batteries is achieved: the conveying device 200 smoothly transports the batteries from the feeding end to the cleaning station, where the cleaning device 300 cleans the battery surface, effectively removing contaminants and improving adhesion; the batteries then enter the positioning station, where the positioning device 400 precisely positions and secures them to prevent displacement or vibration during bonding, ensuring bonding position accuracy; finally, the batteries undergo foam bonding at the bonding station 10, where the bonding devices 500, symmetrically arranged on both sides, simultaneously complete the foam picking, release paper peeling, and bonding actions, achieving double-sided bonding at the same time. This not only significantly improves production efficiency and reduces manual labor intensity but also eliminates secondary positioning errors caused by flipping the batteries, improving product consistency and yield.

[0048] Please see Figures 1 to 5In this utility model of automatic battery foam bonding equipment, multiple functional modules are compactly arranged along the production line, reducing the equipment's footprint and facilitating integration with upstream and downstream processes. Synchronous double-sided bonding avoids intermediate flipping and repeated positioning, reducing both the complexity of the mechanism and the risk of battery damage caused by repeated handling. The automated bonding process eliminates manual contact, preventing contamination and air bubble introduction, further improving bonding quality and long-term reliability. The overall equipment features high speed, high precision, and high stability, making it suitable for large-scale battery manufacturing production lines.

[0049] Please see Figures 1 to 5 In one optional embodiment, the frame 100 serves as the mounting base for each device and can be a rigid welded structure or a bolted assembly frame. Its upper part is provided with multiple mounting surfaces and interfaces for fixing the conveying device 200, cleaning device 300, positioning device 400, and attachment device 500, etc. The bottom of the frame 100 can be equipped with leveling feet to adapt to different ground conditions. The overall structure possesses high rigidity and stability, ensuring that each device maintains a precise relative position during high-speed operation, thereby improving the overall operating accuracy and lifespan of the equipment.

[0050] Please see Figures 1 to 5 In one optional embodiment, the conveying device 200 includes a first driving member 210 and a conveying mechanism 220 driven by the first driving member 210. The cleaning device 300, positioning device 400, and attaching device 500 are arranged sequentially along the conveying direction of the conveying mechanism 220. Specifically, the first driving member 210 may be, for example, a servo motor or a stepper motor, which drives the conveying mechanism 220 through a synchronous belt or gear set. The conveying mechanism 220 may be, for example, a linear conveying mechanism 220 such as a belt conveyor or a roller conveyor, which performs horizontal conveying operations while carrying the battery. To further improve the conveying stability and positioning accuracy, a precision positioning block or guide bar may be provided on the conveying mechanism 220 to effectively prevent the battery from shifting or slipping during the conveying process and ensure the stability of the conveying process.

[0051] Please see Figures 1 to 5In one optional embodiment, cleaning stations, positioning stations, and attaching stations 10 are arranged sequentially and at intervals along the conveying path to form a continuous automated production line. During operation, an industrial robot picks up the battery and precisely places it at the feed end of the conveyor 200. The robot can then immediately perform the picking operation for the next battery, achieving efficient cyclical operation. Driven by the conveyor 200, the battery passes through each station sequentially: first, it undergoes surface treatment by the cleaning device 300 at the cleaning station; then, it enters the positioning station where it is fixed by the positioning device 400; and finally, it arrives at the attaching station 10 to complete the synchronous attachment of double-sided foam. The entire process achieves truly continuous flow operation, which not only greatly improves production cycle time and equipment utilization but also effectively ensures the consistency of the process and the stability of product quality through precise mechanized control. It should be noted that this conveying layout also has good scalability and compatibility, allowing for flexible adjustment of station spacing or addition of functional modules according to actual production needs to meet the attaching requirements of batteries of different specifications.

[0052] Please see Figures 1 to 5 In one optional embodiment, the cleaning device 300 is disposed on opposite sides of the conveying device 200 for pre-treating the surface of the battery before it is attached. The symmetrically arranged cleaning devices 300 on both sides can achieve synchronous processing, completing double-sided cleaning without flipping the battery, which greatly improves cleaning efficiency. This simplifies the equipment structure and avoids secondary surface contamination or mechanical damage that may be caused during the flipping process, laying a solid foundation for the subsequent high-precision attachment process.

[0053] Please see Figures 1 to 5 Specifically, the cleaning device 300 employs a plasma cleaning device 300, with plasma nozzles on both sides aimed at the upper and lower surfaces or opposite sides of the battery, respectively. When the battery passes through the cleaning station with the conveyor 200, the plasma cleaning device 300 is activated, generating a highly active plasma flow to comprehensively treat the battery surface. Using a plasma device for cleaning utilizes the high-energy particles in the plasma to effectively bombard and remove contaminants such as grease and dust adsorbed on the battery surface, achieving ultra-clean treatment. Simultaneously, it activates the molecular chains on the material surface, increasing surface energy and hydrophilicity, thereby significantly improving the adhesion and wettability of the foam adhesive to the battery surface, significantly enhancing the adhesion and bonding reliability of the foam adhesive, and improving the bonding effect. Furthermore, plasma cleaning has advantages such as being non-contact, pollution-free, and non-damaging, not only avoiding the impact of residual chemical solvents on battery performance but also ensuring a high degree of consistency in the treatment effect.

[0054] Please see Figures 1 to 5In one optional embodiment, the positioning device 400 includes a mounting base 410 and a clamping mechanism 420. The mounting base 410 is fixed to the frame 100 and located on both sides of the conveying device 200, providing a stable support base for the clamping mechanism 420. The clamping mechanism 420 is connected to the mounting base 410, is disposed above the conveying device 200, and can reciprocate in a direction perpendicular to the conveying plane to clamp or release the battery. It is used to fix the battery before attachment to ensure accurate positioning and stability of the attachment process, and to release the battery after attachment to transport it to the next process, thereby achieving a high-precision, high-efficiency, and high-reliability positioning function.

[0055] Please see Figures 1 to 5 Specifically, the mounting base 410 spans both sides of the conveying device 200, and the actuator of the clamping mechanism 420 is positioned above the conveying device 200. The clamping mechanism 420 can use a cylinder or an electric push rod as the driving element, and its end effector can be equipped with a soft pressure head or a vacuum suction cup with a buffer structure. This ensures sufficient clamping force while effectively preventing indentations or scratches on the battery surface. After the conveying device 200 transports the battery to the positioning station and positions it precisely, the clamping mechanism 420 quickly presses down, using controllable pressure to firmly press the battery onto the conveying platform. This eliminates any displacement or vibration that may occur during the subsequent attachment process, ensuring the positional accuracy of the foam attachment, avoiding attachment deviations caused by battery movement, and providing necessary process stability for simultaneous attachment operations on both sides. While ensuring positioning reliability, it effectively protects the appearance quality of the battery product, effectively improving the overall production yield and the level of equipment automation. After the attachment process is completed, the clamping mechanism 420 quickly lifts up to release the battery, and the conveying device 200 then smoothly transports it to the next process, achieving seamless connection between each station.

[0056] Please see Figures 1 to 5 In one optional embodiment, the positioning station and the attachment station 10 overlap. This allows the battery to be positioned and attached at the same location. After the battery is fixed by the positioning device 400, the attachment device 500 moves to the positioning station (i.e., the attachment station 10) to simultaneously attach foam to both sides of the battery. This reduces intermediate material transfer steps, lowers cumulative positioning errors, simplifies the equipment structure, and improves system rigidity and response speed. In other embodiments, the positioning station and the attachment station 10 can also be arranged adjacent to each other, with a transfer mechanism used to transfer the battery between the two stations to adapt to different process layout requirements.

[0057] Please see Figures 1 to 5In one optional embodiment, the attaching device 500 is mounted on the frame 100 and includes a rotary attaching mechanism 510 and a release paper peeling mechanism 520. The rotation plane of the rotary attaching mechanism 510 is perpendicular to the conveying direction of the conveying device 200. This orthogonal layout optimizes the space utilization of the equipment and avoids motion interference between mechanisms. Furthermore, it enables the attaching device 500 to achieve multi-station continuous operation through rotary motion, significantly improving equipment utilization and production cycle time. The release paper peeling mechanism 520 and the rotary attaching mechanism 510 are designed collaboratively. Their installation positions and movement trajectories are precisely calculated to ensure that the release paper peeling and recycling operations can be accurately completed before foam attaching, achieving truly fully automated production. This completely avoids the pollution of the production environment by release paper residue and maintains the cleanliness of the work site. The release paper peeling mechanism works closely with the attaching unit to shorten the movement path of the paper tearing process, further improving cycle time efficiency.

[0058] Please see Figures 1 to 5 It should be noted that the rotary bonding mechanism 510 and the release paper peeling mechanism 520 achieve motion coordination through an integrated control system. The control program design considers the timing coordination and motion trajectory optimization between the various mechanisms to ensure high-speed and stable operation of the entire bonding process. This highly coordinated automated design not only guarantees the consistency of bonding accuracy but also significantly improves overall production efficiency by reducing intermediate waiting time, while also reducing quality fluctuations that may be caused by manual intervention. The overall design embodies a high degree of mechatronics integration, achieving high-efficiency, high-precision, and high-reliability production of the foam bonding process through the organic combination of rotary multi-station operation and automated peeling, providing key technological support for the large-scale automated manufacturing of power batteries.

[0059] Please see Figures 1 to 5 In one optional embodiment, the rotary attaching mechanism 510 includes a rotary mechanism 511 and multiple attaching units 512. The rotary mechanism 511 is rotatably mounted on the frame 100. The multiple attaching units 512 are respectively connected to the rotary mechanism 511 and arranged circumferentially along the rotary mechanism 511, and are driven by the rotary mechanism 511 to perform synchronous circular motion. Through the circumferentially multi-station layout of the attaching units 512, multiple stations such as feeding, release paper peeling, attaching, and preparation can be performed synchronously, forming a continuous production cycle and significantly improving production efficiency. The circumferentially distributed multiple attaching units 512 also ensure good load balance characteristics of the equipment, reducing vibration and impact during rotation, which is beneficial to improving attaching accuracy and extending equipment life. At the same time, this layout optimizes the spatial configuration of each functional module, ensuring both operational convenience and a compact equipment structure.

[0060] Please see Figures 1 to 5Understandably, when one bonding unit 512 is performing a bonding operation, other units can simultaneously complete preparatory actions such as foam picking and release paper peeling, eliminating the waiting time in traditional single-station operations. This not only significantly improves the equipment's continuous operation capability and production efficiency but also achieves high-speed and smooth transitions between stations through the characteristics of rotary motion. The rotary multi-station design enables the equipment to achieve highly efficient continuous production within a limited space, significantly improving the automation level and production cycle of foam bonding, and providing reliable process assurance for large-scale battery manufacturing.

[0061] Please see Figures 1 to 5 In an optional embodiment, the attachment unit 512 is used to perform the temporary storage, transfer, and final attachment of the foam. Specifically, the attachment unit 512 is a vacuum adsorption component, comprising an adsorption array consisting of one or more vacuum suction cups or nozzles, connected to a vacuum generating device via a vacuum pipeline system. This vacuum adsorption mechanism reliably grips the foam using a stable negative pressure adsorption force, effectively preventing displacement or deformation of the foam during transfer. Furthermore, due to the non-contact adsorption method, it completely avoids indentations or damage to the foam that might be caused by mechanical clamping, maximizing the preservation of the foam's structural integrity and appearance quality, and significantly improving the consistency and reliability of the attachment quality.

[0062] Please see Figures 1 to 5 In an optional embodiment, the attachment unit 512 may also be equipped with a flexible contact interface and pressure sensing function, which can adapt to foam materials of different specifications, ensure uniform distribution of adsorption force, and avoid local stress concentration. During operation, the attachment unit 512 moves synchronously with the rotating mechanism 511, passing through different positions in sequence and completing a series of operations such as precise foam picking, release paper peeling, and final attachment. The multi-station collaborative operation mode enables the attachment unit 512 to achieve continuous production, greatly improving the production efficiency and automation level of the equipment.

[0063] Please see Figures 1 to 5In one optional embodiment, the rotating mechanism 511 includes a second driving member 5111 and a rotating part. The second driving member 5111 is connected to the frame 100 and is fixed to the frame 100 as the core power source. The axial direction of its output shaft is parallel to the conveying direction of the conveying device 200, ensuring the orthogonality between the rotation plane and the conveying flow direction. Multiple rotating parts are connected to the output shaft of the second driving member 5111 through bearing assemblies and are arranged circumferentially. Each attachment unit 512 is installed at the cantilever end of the rotating part away from the second driving member 5111, forming a stable rotational motion system. The second driving member 5111 drives the rotating part and the attachment unit 512 to perform circular motion around the second driving member 5111. The second driving component 5111 can be a servo motor, which, in conjunction with a high-precision reducer or direct drive, achieves speed control to ensure the positioning accuracy of the bonding unit 512 when switching between multiple workstations, and guarantees the timing synchronization and spatial consistency of operations at each workstation, thus providing a guarantee for high-quality bonding. The continuity and stability of the rotational motion enable each bonding unit 512 to achieve seamless cyclic operation, significantly improving the production efficiency and operational reliability of the equipment, and also adapting to the requirements of different production cycles.

[0064] Please see Figures 1 to 5 In one optional embodiment, the rotating part includes a rotating frame 5112 and a third driving member 5113. The rotating frame 5112 is connected to the output shaft of the second driving member 5111 and arranged circumferentially along the second driving member 5111; the attaching unit 512 is slidably connected to the rotating frame 5112 via the third driving member 5113, which drives the attaching unit 512 to move closer to or away from the battery. Each attaching unit 512 is equipped with an independent third driving member 5113, and the precise positioning and coordinated movement of each unit are achieved through a control system. Through the coordinated design of the rotating frame 5112 and the third driving member 5113, precise control of the attaching unit 512 in two degrees of freedom—circular motion and radial linear motion—is achieved, providing a reliable guarantee for high-quality and high-efficiency foam attaching processes.

[0065] Please see Figures 1 to 5Specifically, the third driving component 5113 can be, for example, a motor and a push rod. One end of the push rod is connected to the motor, and the other end is connected to the attachment unit 512. Each attachment unit 512 corresponds to at least one push rod. During operation, the push rod is driven by the motor to move, thereby pushing the attachment unit 512 to a predetermined position to perform operations such as foam buffering, release paper peeling, and foam attachment. The third driving component 5113 can control the attachment unit 512 to accurately attach the foam to the battery surface at a set speed and pressure, avoiding damage to the battery surface or the foam due to pressure. It should be noted that the third drive unit 5113 provides precise displacement and pressure control. It can adjust the bonding parameters according to different foam materials and battery specifications to ensure stable bonding quality. The push rod end and the bonding unit 512 can also be flexibly connected to avoid damage to the battery surface or deformation of the foam caused by rigid impact. Furthermore, it can integrate pressure sensing to monitor the contact pressure during the bonding process in real time and dynamically adjust the output force to ensure uniform, bubble-free bonding between the foam and the battery surface, improving bonding consistency and maximizing the protection of the battery and foam integrity. Each bonding unit 512 is driven independently, allowing the equipment to adapt to battery products of different sizes and improving production capacity. It is understood that the structure of the third drive unit 5113 is not limited; for example, linear drive components such as cylinders can be used to push the bonding unit 512 radially for operations such as foam buffering and foam bonding to the battery surface.

[0066] Please see Figures 1 to 5 In one optional embodiment, the rotating frame 5112 is circumferentially arranged with four sets of attaching units 512, with an included angle of 90 degrees between adjacent attaching units 512, forming a symmetrical four-station layout. When the rotating frame 5112 rotates intermittently, the movement paths of the four sets of attaching units 512 sequentially pass through the feeding station 40, the peeling station 30, the transition station 20, and the attaching station 10, forming a continuous production cycle. Through the four-station cycle design, multiple actions such as continuous foam feeding, release paper peeling, pre-attachment, and attachment can be performed in parallel, greatly improving equipment capacity and production cycle time, and avoiding waiting time in single-station operations. It is understood that the number of attaching units 512 and the structure of the rotating frame 5112 are not limited. For example, the transition station 20 may not be provided, or other stations may be added according to production needs. The collaborative design of each component is sufficient to ensure continuous circulation and consistent production cycle time.

[0067] Please see Figures 1 to 5Specifically, taking a certain attachment unit 512 as an example, when it is located at the feeding station 40, it is opposite to the foam feeding port. At this time, the push rod pushes the attachment unit 512 closer to the foam and starts the vacuum adsorption system to adsorb the foam for buffering. After buffering is completed, it resets. Then, the rotating frame 5112 rotates 90°, driving the attachment unit 512 to the peeling station 30, where it works with the release paper peeling mechanism 520 to complete the release paper removal operation. Then, the rotating frame rotates again, driving the attachment unit 512 to the transition station 20 for process preparation. It can be understood that due to the operation of each station... The operation is carried out simultaneously. At this time, the attaching units 512 of other stations are performing foam feeding, release paper peeling and foam attaching operations respectively. After the other stations have completed their operations, the rotating frame 5112 rotates and drives the attaching unit 512 of the transition station 20 to the attaching station 10. At this time, the attaching unit 512 is opposite to the side of the battery. The push rod pushes the attaching unit 512 close to the battery and attaches the foam to the battery surface with controllable pressure. After the attaching is completed, it resets. The rotating frame 5112 continues to rotate and drives the attaching unit 512 to the feeding station 40, and repeats the above operation cycle.

[0068] Please see Figures 1 to 5 It should be noted that the above describes one cycle of the attaching unit 512. On the production line, the operations of the four stations are completely synchronized, with each set of attaching units 512 performing their respective operations simultaneously at their respective stations. The attaching devices 500 on both sides of the feeding device maintain strict synchronous movement, precisely coordinating with the rhythm of the conveying device 200 to achieve uninterrupted continuous production. The multi-station collaborative design significantly improves production efficiency, and standardized operating procedures ensure consistent product quality. Furthermore, the modular design allows the equipment to adjust the number or function of stations according to production needs, meeting the production process requirements of different products.

[0069] Please see Figures 1 to 5 It is understandable that the third drive unit 5113 has different functions at different workstations. At the feeding station 40, it assists in precise material picking; at the peeling station 30, it assists in the peeling operation; and at the bonding station 10, it completes precise bonding. The third drive unit 5113 at each workstation works collaboratively according to a preset program, and precise motion control ensures the timing accuracy and spatial precision of each action.

[0070] Please see Figures 1 to 5In an optional embodiment, the release paper peeling mechanism 520 is mounted on the frame 100 and positioned adjacent to the movement path of the attachment unit 512. The release paper peeling mechanism 520 includes a peeling actuator 521 slidably connected to the frame 100, which can slide along a linear guide rail between the peeling station 30 and the recycling station. When the peeling actuator 521 moves to the peeling station 30, it is positioned opposite the attachment unit 512 and can work with the attachment unit 512 to complete the release paper peeling operation. A recycling container 522 is provided below the recycling station to collect the peeled release paper. When the attachment unit 512, carrying foam, rotates to the peeling station 30, the peeling actuator 521 accurately moves to the working position and grabs the release paper. Subsequently, the actuator moves smoothly along a predetermined trajectory to the recycling station, and the release paper is released into the recycling container 522 by releasing the vacuum or blowing air. Automated peeling ensures consistent and reliable release paper removal, avoiding incomplete peeling or foam damage that may occur with manual operation. The closed recycling system maintains a clean working environment and prevents pollution caused by scattered release paper. The coordinated operation with the rotary attachment mechanism 510 achieves seamless integration of the production process, maximizing the equipment's production efficiency. Its structural layout ensures effective space for peeling operations while avoiding interference with surrounding components, ensuring the stability and reliability of equipment operation. It also has good adaptability, allowing peeling parameters to be adjusted according to different specifications of foam products.

[0071] Please see Figures 1 to 5 In one optional embodiment, the peeling actuator 521 includes a vacuum suction head connected to a vacuum source via a conduit. The vacuum suction head is made of a soft material such as silicone or polyurethane, ensuring sufficient suction force while avoiding scratching the release paper or foam. Through precise control of the vacuum suction force, it reliably grips the edge of the release paper and achieves a smooth and consistent peeling action under the action of a sliding mechanism such as a slide rail, ensuring that the release paper separates from the foam adhesive at the optimal angle and speed.

[0072] Please see Figures 1 to 5 In one optional embodiment, the recycling container 522 is a box with an opening at the top, located below the recycling position. The box can be made of metal or plastic to facilitate the centralized collection and regular cleaning of the release paper. The opening is directly opposite the release point of the peeling actuator 521 to ensure that the release paper falls accurately into the box, avoiding scattering and polluting the environment and causing equipment failure.

[0073] Please see Figures 1 to 5In one optional embodiment, when the attaching unit 512 moves to the peeling station 30, the peeling actuator 521 simultaneously slides to a predetermined position on the peeling station 30, maintaining a precise relative posture with the attaching unit 512. At this time, the peeling actuator 521 and the attaching unit 512 work together, reliably gripping and smoothly peeling the release paper from the foam surface through the controllable vacuum suction force generated by the peeling actuator 521. After completing the peeling action, the peeling actuator 521 immediately moves rapidly along the linear guide rail to the recycling station, accurately placing the release paper into the recycling bin through a vacuum release mechanism. Simultaneously, the attaching unit 512, having completed the peeling operation, rotates to the next station to continue the subsequent process, while the subsequent attaching unit 512 simultaneously enters the peeling station 30, cooperating again with the returning peeling actuator 521 to perform a new round of peeling operations. This precise timing coordination ensures a seamless connection between the peeling process and the rotary attaching process, forming a continuous and efficient work cycle.

[0074] Please see Figures 1 to 5 It should be noted that this collaborative working mechanism is implemented through a control system, which precisely coordinates the timing of the actions of the rotating mechanism 511 and the linear motion mechanism to ensure that the entire peeling process and the attachment process are strictly synchronized.

[0075] Please see Figures 1 to 5 In one optional embodiment, after the battery is fed into the conveying device 200, it first enters the cleaning station, where the plasma cleaning device 300 simultaneously cleans both surfaces to remove oil and enhance adhesion. After cleaning, the battery continues to be conveyed to the positioning station, where the positioning device 400 accurately positions the battery using a monitoring system, and the pressing mechanism 420 fixes the battery with controllable pressure. Simultaneously, the attaching unit 512, driven by the rotating mechanism 511, completes multi-station collaborative operations: it picks up foam at the feeding station 40, rotates to the peeling station 30 to cooperate with the release paper peeling mechanism 520 to remove the release paper, and then rotates to the attaching station 10, where the third driving component 5113 pushes the attaching unit 512 to press the foam onto both sides of the battery. After attachment, the pressing mechanism 420 releases the battery, and the conveying device 200 delivers the finished product, completing a full production cycle. The entire process is fully automated through an integrated control system, ensuring the synchronization and coordination of each link. Full automation greatly reduces the need for manual intervention, not only reducing labor intensity but also avoiding quality fluctuations caused by human factors, ensuring the consistency and stability of process parameters, and significantly improving bonding accuracy and product quality. The multi-station parallel operation mode greatly improves equipment utilization and production cycle time, providing a reliable technical guarantee for the large-scale high-quality production of power batteries.

[0076] In summary, this utility model's automatic battery foam bonding equipment, through integrated layout and multi-station collaborative design, achieves fully automated production of double-sided battery foam bonding. The collaborative layout of the conveying device 200, plasma cleaning device 300, positioning device 400, and symmetrically arranged rotary bonding device 500 enables continuous battery conveying, surface treatment, precise positioning, and synchronous double-sided bonding. The precise coordination between the rotary multi-station bonding mechanism and the release paper peeling mechanism 520 achieves parallel operations of automatic foam feeding, release paper peeling, and precise bonding. Combined with plasma surface treatment and pressing positioning, it significantly improves bonding quality and product consistency. It effectively solves the problems of low efficiency, unstable quality, and high labor intensity in battery foam bonding, and has significant advantages in high reliability, high precision, and high production cycle time, making it particularly suitable for large-scale automated production lines for power batteries.
