Description

Technical Field

[0002] 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 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 application, the battery must be rotated 180° and the above steps repeated. This process is cumbersome and inefficient. Furthermore, manual operation makes it difficult to guarantee the consistency and accuracy of the application position, easily leading to quality problems such as misalignment, slant application, or air bubbles, severely impacting product yield and production capacity.

[0003] To overcome the drawbacks of manual operation, some automated equipment uses robotic arms to grasp and attach foam. However, automated equipment has limited functions and complex structures, and still suffers from cumbersome procedures and low efficiency. Utility Model Content

Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0041] 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.

[0042] 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.

[0043] In the assembly and production of products such as lithium batteries, it is often necessary to attach foam with adhesive backing to specific locations on their surface. The attachment process involves individually picking up foam with release paper, peeling off the release paper, aligning it, and then attaching it to the battery surface. For double-sided attachment, the battery must be rotated 180°, and the entire process repeated. This is cumbersome, inefficient, and manual operation makes it difficult to guarantee the consistency and accuracy of the attachment position, severely impacting product yield and production capacity. While some automated equipment uses robotic arms to grasp and attach foam, these still suffer from limitations such as limited functionality, complex structure, cumbersome procedures, and low efficiency.

[0044] Please see Figures 1 to 6 This invention provides an attachment execution device 100, comprising a mounting base 110, a rotating mechanism 120, multiple attachment units 130, and a release paper peeling mechanism 140. The mounting base 110 serves as the supporting foundation for the overall structure, used to fix and install various functional components. The rotating mechanism 120 is rotatably mounted on the mounting base 110. The multiple attachment units 130 are connected to the rotating mechanism 120 and arranged circumferentially thereafter, driven by the rotating mechanism 120 to perform circular motion. During the motion, the attachment units 130 adsorb foam and attach it to the side of the battery. The release paper peeling mechanism 140 is connected to the mounting base 110 and is arranged adjacent to the motion path of the attachment units 130 to peel the release paper off the foam adsorbed on the attachment units 130. During the rotation of the rotating mechanism 120, the multiple attachment units 130 perform continuous circular motion and cooperate with other mechanisms to complete the foam picking, release paper peeling, and attachment operations. In this attaching execution device 100, the rotating mechanism 120 and the attaching unit 130 constitute a rotary attaching mechanism. Through the design of rotary drive and multi-station collaboration, a high degree of automation of the foam attaching process is achieved. The rotating mechanism 120 drives multiple attaching units 130 to circulate through multiple stations, enabling each unit to perform corresponding operations synchronously at different stages, thereby significantly improving attaching efficiency and rhythm consistency. At the same time, the coordinated action of the release paper peeling mechanism 140 and the attaching unit 130 achieves precise tearing and automatic recycling of the release paper, avoiding manual intervention, improving the stability and reliability of attaching quality, preventing release paper residue from polluting the production environment, and maintaining the cleanliness of the work site. The overall structure is compact and the operation process is smooth, making it suitable for the high-precision, high-efficiency attaching requirements of side foam for products such as batteries.

[0045] It should be noted that the release liner peeling mechanism 140 and the rotary bonding mechanism are designed collaboratively. Their installation positions and motion trajectories are precisely calculated to ensure accurate peeling and recycling of the release liner before foam bonding, achieving truly fully automated production. Specifically, the rotary bonding mechanism and the release liner peeling mechanism 140 can achieve motion coordination through an integrated control system. The control program design considers the timing coordination and motion trajectory optimization between the mechanisms to ensure high-speed and stable operation of the entire bonding process. The highly collaborative automation design not only ensures the consistency of bonding accuracy but also significantly improves overall production efficiency by reducing intermediate waiting time, while reducing quality fluctuations that may be caused by manual intervention. The overall design embodies a high degree of mechatronics, 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 technical support for the large-scale automated manufacturing of power batteries.

[0046] Please see Figures 1 to 6 In an optional embodiment, the mounting base 110 may be a rigid welded structure or a bolted assembly frame, with multiple mounting planes and interfaces on its upper part for fixing the components. The bottom may be equipped with leveling feet to adapt to different ground conditions. The overall structure has high rigidity and stability, ensuring that the components maintain a precise relative position during high-speed operation, thereby improving the overall operating accuracy and lifespan of the device.

[0047] Please see Figures 1 to 6 In an optional embodiment, the rotating mechanism 120 includes a first driving member 121 and a rotating part. The first driving member 121 is connected to the mounting base 110 and serves as the core power source. The axial direction of the output shaft of the first driving member 121 is parallel to the battery delivery direction, ensuring the orthogonality between the rotation plane and the delivery flow direction. The rotating part is connected to the output shaft of the first driving member 121 through a bearing assembly and can rotate accordingly. A plurality of the rotating parts are arranged circumferentially along the first driving member 121. The attachment unit 130 is mounted on the end of the rotating part away from the first driving member 121. The first driving member 121 drives the rotating part and the attachment unit 130 to perform circular motion around the first driving member 121. The first driving component 121 can be, for example, 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 130 when switching between multiple workstations, ensuring the timing synchronization and spatial consistency of operations at each workstation, and providing a guarantee for high-quality bonding; the continuity and stability of the rotational motion enable each bonding unit 130 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.

[0048] Please see Figures 1 to 6In an optional embodiment, the rotating part includes a rotating frame 122 and a second driving member 123. The rotating frame 122 is connected to the output shaft of the first driving member 121 and arranged circumferentially along the first driving member 121; the attaching unit 130 is slidably connected to the rotating frame 122 via the second driving member 123, and the second driving member 123 drives the attaching unit 130 to move closer to or away from the battery. Each attaching unit 130 is equipped with an independent second driving member 123, and the precise positioning and coordinated movement of each unit are achieved through a control system. Through the coordinated design of the rotating frame 122 and the second driving member 123, precise control of the attaching unit 130 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.

[0049] Please see Figures 1 to 6 In one optional embodiment, the second driving member 123 includes a motor and a push rod. The motor is fixed to the rotating frame 122, and one end of the push rod is connected to the motor, while the other end is connected to the attachment unit 130. The motor drives the push rod to move, causing the attachment unit 130 to reciprocate along its axial direction to approach or move away from the battery. Each attachment unit 130 corresponds to at least one second driving member 123. During operation, the motor drives the push rod to move, thereby pushing the attachment unit 130 to a predetermined position to perform operations such as foam buffering, release paper peeling, and foam attachment. The second driving member 123 can control the attachment unit 130 to accurately attach the foam to the battery surface at a set speed and pressure, avoiding pressure damage to the battery surface or the foam.

[0050] It should be noted that the second drive unit 123 provides precise displacement and pressure control, and can adjust the bonding parameters according to different foam materials and battery specifications to ensure the stability of bonding quality. The end of the push rod and the bonding unit 130 can also adopt a flexible connection to avoid damage to the battery surface or deformation of the foam caused by rigid impact. Furthermore, it can also integrate pressure sensing function to monitor the contact pressure during the bonding process in real time and dynamically adjust the output force to ensure uniform and bubble-free bonding between the foam and the battery surface, improve bonding consistency, and maximize the protection of the integrity of the battery and foam. Each bonding unit 130 is driven independently, which allows the equipment to adapt to battery products of different sizes and improves the production capacity of the equipment. It is understood that the structure of the second drive unit 123 is not limited. For example, linear drive components such as cylinders can also be used to push the bonding unit 130 to move radially for operations such as foam buffering and foam bonding to the battery surface.

[0051] Please see Figures 1 to 6In one optional embodiment, the attaching units 130 are evenly distributed circumferentially along the rotating mechanism 120. Combined with the circumferential multi-station layout, multiple processes such as feeding, release paper peeling, attaching, and preparation can be carried out simultaneously, forming a continuous production cycle and significantly improving production efficiency. The circumferentially distributed multiple attaching units 130 also ensure good load balance characteristics of the equipment, reduce vibration and impact during rotation, and help improve attaching accuracy and extend equipment service life. This layout optimizes the spatial configuration of each functional module, ensuring both operational convenience and a compact equipment structure.

[0052] Understandably, when one bonding unit 130 is performing a bonding operation, other units can complete preparatory actions such as foam picking and release paper peeling in parallel, 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.

[0053] Please see Figures 1 to 6 In an optional embodiment, the attachment unit 130 is used to perform the temporary storage, transfer, and final attachment of the foam. Specifically, the attachment unit 130 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.

[0054] Please see Figures 1 to 6 In an optional embodiment, the attachment unit 130 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 130 moves synchronously with the rotating mechanism 120, 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 130 to achieve continuous production, greatly improving the production efficiency and automation level of the equipment.

[0055] Please see Figures 1 to 6In one optional embodiment, four sets of attaching units 130 are evenly arranged circumferentially on the rotating frame 122, with an included angle of 90 degrees between adjacent attaching units 130. When the rotating frame 122 rotates, the movement paths of the four sets of attaching units 130 sequentially pass through the feeding station 10, the peeling station 20, the transition station 30, and the attaching station 40, forming a continuous production cycle. Through this 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 130 and the structure of the rotating frame 122 are not limited; for example, the transition station 30 may not be provided, or other stations may be added according to production needs. The coordinated design of each component ensures continuous circulation and consistent production cycle time.

[0056] Specifically, the foam feeding port 150 is fixed on the mounting base 110, and the foam is stacked sequentially at the feeding port 150. Taking a certain attachment unit 130 as an example, when it is located at the feeding station 10, it is opposite to the foam feeding port 150. At this time, the push rod pushes the attachment unit 130 close to the foam and starts the vacuum adsorption system to adsorb the foam for buffering. After buffering is completed, it is reset. Then, the rotating frame 122 rotates 90°, driving the attachment unit 130 to the peeling station 20, where it works with the release paper peeling mechanism 140 to complete the release paper removal operation. Then, the rotating frame rotates again, driving the attachment unit 130 to the transition station 30 for further processing. During process preparation, it is understandable that since the operations of each station are carried out simultaneously, the attaching units 130 of other stations are performing foam feeding, release paper peeling, and foam attaching operations respectively. After the operations of other stations are completed, the rotating frame 122 rotates and drives the attaching unit 130 of the transition station 30 to the attaching station 40. At this time, the attaching unit 130 is opposite to the side of the battery. The push rod pushes the attaching unit 130 close to the battery and attaches the foam to the battery surface with controllable pressure. After attaching, it resets and the rotating frame 122 continues to rotate and drives the attaching unit 130 to the feeding station 10, repeating the above operation cycle.

[0057] It should be noted that the above describes one cycle of the attaching unit 130. On the production line, the operations of the four stations are completely synchronized, with each set of attaching units 130 performing its corresponding operation simultaneously at its respective station. The attaching execution devices 100 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 the standardized operating procedures ensure consistent product quality. Furthermore, the modular design allows the number or function of the stations to be adjusted according to production needs, meeting the production process requirements of different products.

[0058] Understandably, the second drive unit 123 functions differently at different workstations. At the feeding station 10, it assists in precise material picking; at the peeling station 20, it assists in the peeling operation; and at the bonding station 40, it completes precise bonding. The second drive unit 123 at each workstation works collaboratively according to a preset program, and precise motion control ensures the timing accuracy and spatial precision of each action.

[0059] Please see Figures 1 to 6 In an optional embodiment, the release paper peeling mechanism 140 includes a peeling actuator 141 slidably connected to the mounting base 110. The peeling actuator 141 is movable between the working position corresponding to the peeling station 20 and the recycling station. A recycling section 142 is provided below the recycling station. Specifically, the peeling actuator 141 is arranged adjacent to the movement path of the attachment unit 130 and can slide along a linear guide rail between the peeling station 20 and the recycling station. When the peeling actuator 141 moves to the peeling station 20, it is positioned opposite to the attachment unit 130 and can cooperate with the attachment unit 130 to complete the release paper peeling operation. The recycling section 142 is a box with an opening at the top, located below the recycling station, for collecting the peeled release paper. The box can be made of metal or plastic to facilitate centralized collection and periodic cleaning of the release paper. The opening is directly opposite the release point of the peeling actuator 141 to ensure that the release paper falls accurately into the box, avoiding scattering and environmental pollution and equipment malfunction.

[0060] When the attaching unit 130, carrying foam, rotates to the peeling station 20, the peeling actuator 141 accurately moves to the working position and grabs the release paper. Subsequently, the actuator smoothly moves along a predetermined trajectory to the recycling station, where the release paper is released into the recycling container by releasing the vacuum or air blowing. Automated peeling ensures the consistency and reliability of release paper removal, avoiding incomplete peeling or foam damage that may occur with manual operation. The closed recycling system maintains a clean working environment, preventing pollution caused by scattered release paper. The coordinated operation with the rotary attaching mechanism achieves seamless integration of the production process, maximizing equipment 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 for adjustment of peeling parameters according to different specifications of foam products.

[0061] Please see Figures 1 to 6In an optional embodiment, the peeling actuator 141 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.

[0062] Please see Figures 1 to 6 In one optional embodiment, when the attaching unit 130 moves to the peeling station 20, the peeling actuator 141 simultaneously slides to a predetermined position on the peeling station 20, maintaining a precise relative posture with the attaching unit 130. At this time, the peeling actuator 141 and the attaching unit 130 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 141. After completing the peeling action, the peeling actuator 141 immediately moves rapidly along a 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 130, having completed the peeling operation, rotates to the next station to continue subsequent processes, while subsequent attaching units 130 simultaneously enter the peeling station 20, cooperating again with the returning peeling actuator 141 to perform a new round of peeling operations. This precise timing coordination ensures seamless connection between the peeling process and the rotary attaching process, forming a continuous and efficient work cycle.

[0063] 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 120 and the linear motion mechanism to ensure that the entire peeling process and the attachment process are strictly synchronized.

[0064] Please see Figures 1 to 6 This utility model also proposes an attachment device, including an attachment execution device 100 as described in the above embodiments, which is disposed on the battery transport path for foam attachment and cooperates with other devices to achieve automated production. Specifically, the attachment device also includes a conveying device 200, a cleaning device 300, and a positioning device 400. The conveying device 200 sequentially transports the battery to a cleaning station, a positioning station, and an attachment station 40; the cleaning device 300, the positioning device 400, and the attachment execution device 100 are arranged along the transport path of the conveying device 200 and correspond to the cleaning station, the positioning station, and the attachment station 40, respectively; the two attachment execution devices 100 are symmetrically arranged on opposite sides of the conveying device 200, enabling simultaneous foam attachment to both sides of the battery.

[0065] Please see Figures 1 to 6In one optional embodiment, the integrated layout enables a fully automated process for battery foam attachment: the conveying device 200 smoothly transports the battery from the feeding end to the cleaning station, where the cleaning device 300 cleans the battery surface, effectively removing contaminants and improving adhesion; the battery then enters the positioning station, where the positioning device 400 precisely positions and secures it to prevent displacement or vibration during attachment, ensuring attachment position accuracy; finally, the battery undergoes foam attachment at the attachment station 40, where symmetrically arranged attachment execution devices 100 simultaneously complete the foam picking, release paper peeling, and attachment actions, achieving double-sided attachment simultaneously. This not only significantly improves production efficiency and reduces manual labor intensity but also eliminates secondary positioning errors caused by battery flipping, improving product consistency and yield.

[0066] Please see Figures 1 to 6 In one optional embodiment, the conveying device 200, cleaning device 300, and positioning device 400 are all mounted on corresponding mounting bases 110. Multiple functional modules are compactly arranged along the production line direction. At the same time, the rotation plane of the rotary bonding mechanism is perpendicular to the conveying direction of the conveying device 200. This layout optimizes the use of equipment space and avoids motion interference between mechanisms. It also facilitates connection with upstream and downstream processes, enabling the bonding execution device 100 to achieve multi-station continuous operation in a rotary motion mode, significantly improving equipment utilization and production cycle time. Synchronous double-sided bonding avoids intermediate flipping and repeated positioning, which reduces the complexity of the mechanism and the risk of battery damage caused by repeated handling. The automated bonding process eliminates manual contact, avoids contamination and air bubble introduction, and further improves bonding quality and long-term reliability. The overall equipment has the characteristics of high speed, high precision, and high stability, and is suitable for large-scale battery manufacturing production lines.

[0067] Please see Figures 1 to 6 In an optional embodiment, the conveying device 200 includes a third driving member 210 and a conveying mechanism 220 driven by the third driving member 210. The cleaning device 300, the positioning device 400, and the attachment execution device 100 are arranged sequentially along the conveying direction of the conveying mechanism 220 to form a continuous automated production line. The third 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 batteries. To further improve conveying stability and positioning accuracy, precision positioning blocks or guide strips may be provided on the conveying mechanism 220 to effectively prevent the batteries from shifting or slipping during conveying and ensure the stability of the conveying process.

[0068] During operation, the industrial robot picks up the battery and precisely places it at the feed end of the conveyor 200. The robot can then immediately pick up the next battery. Driven by the conveyor 200, the batteries sequentially pass through each station for surface cleaning and foam attachment, achieving efficient cyclical operation. The entire process realizes true continuous production, greatly improving production cycle time and equipment utilization, and effectively ensuring process consistency and product quality stability. This conveyor layout also has good scalability and compatibility, allowing for flexible adjustment of station spacing or addition of functional modules to meet the attachment requirements of batteries of different specifications, according to actual production needs.

[0069] Please see Figures 1 to 6 In one optional embodiment, the cleaning device 300 is disposed on opposite sides of the conveying device 200. A plasma cleaning device 300 is used, with plasma nozzles on both sides targeting the upper and lower surfaces or opposite sides of the battery for cleaning. The high-energy particles in the plasma effectively bombard and remove contaminants such as grease and dust adsorbed on the battery surface, achieving ultra-clean treatment. Simultaneously, it significantly improves the adhesion and bonding reliability of the foam adhesive, enhancing the bonding effect. Plasma cleaning not only avoids the impact of residual chemical solvents on battery performance but also ensures a high degree of consistency in the treatment effect. The symmetrical arrangement of the two sides allows for synchronous processing without flipping the battery, greatly improving cleaning efficiency. This simplifies the equipment structure and avoids secondary surface contamination or mechanical damage that may occur during flipping, laying the foundation for subsequent high-precision bonding.

[0070] Please see Figures 1 to 6 In one optional embodiment, the positioning device 400 includes a mounting base 410 spanning both sides of the conveying device 200 and a clamping mechanism 420 connected to the mounting base 410. The clamping mechanism 420 is positioned above the conveying device 200 and can reciprocate in a direction perpendicular to the conveying plane to clamp or release the battery. This is used to fix the battery before attachment to ensure accurate positioning and stability during the attachment process, and to release the battery after attachment to transport it to the next process. This achieves high-precision, high-efficiency, and high-reliability positioning, ensuring the positional accuracy of the foam attachment, avoiding attachment deviations caused by battery movement, effectively protecting the appearance quality of the battery product, and improving overall production yield and equipment automation level. After the attachment process is completed, the clamping mechanism 420 quickly lifts and releases the battery, and the conveying device 200 then smoothly transports it to the next process, achieving seamless connection between each workstation.

[0071] Please see Figures 1 to 6In one optional embodiment, the positioning station and the attachment station 40 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 execution device 100 moves to the positioning station (i.e., the attachment station 40) and simultaneously attaches 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 40 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.

[0072] Please see Figures 1 to 6 In one optional embodiment, after the battery is fed into the conveying device 200, it first enters the cleaning station, where both sides are simultaneously cleaned by a plasma nozzle. 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 130, driven by the rotating mechanism 120, completes multi-station collaborative operations: it picks up foam at the feeding station 10, rotates to the peeling station 20 to cooperate with the release paper peeling mechanism 140 to remove the release paper, and then rotates to the attaching station 40, where the second driving component 123 pushes the attaching unit 130 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.

[0073] In summary, the bonding execution device 100 and bonding equipment of this utility model, through the precise cooperation of the rotary multi-station bonding mechanism and the release paper peeling mechanism 140, realize the parallel operation of automatic foam feeding, release paper peeling and precise bonding, achieving fully automated operation; the side arrangement of the rotary structure design and the nearby placement of the release paper peeling mechanism 140 optimize the spatial layout and process connection, automatically recycle waste, and optimize environmental management; the push rod controls the precise movement of the bonding unit 130, improving the bonding quality; the bonding equipment, through the collaborative design of multiple stations and multiple devices, can realize the fully automated production of double-sided battery foam bonding, improving bonding accuracy and consistency; it effectively solves the problems of low efficiency, unstable quality and high labor intensity in battery foam bonding, and has significant advantages of high reliability, high precision and high production cycle, making it particularly suitable for large-scale automated production lines for power batteries.
