[0002] In the battery industry, the research and development and application of pole piece reel changing systems are receiving more and more attention. The existing technology generally adopts a manual reel changing method, where operators manually connect and alternate between new and old reels. Although this method meets production needs to a certain extent, the production efficiency is significantly limited due to the cumbersome operation process and high skill requirements for operators. In addition, during the manual operation process, it is easy for the pole piece position to be inaccurate or the tape to be loosely bonded, thus affecting the quality of the final product.

[0003] The existing manual roll-changing method still has certain safety hazards. In specific operations, the direct contact between the tape and the electrode may cause risks such as electric shock and injury to the operator, and even lead to safety accidents in serious cases. This not only affects the smoothness of production, but also makes the operator bear greater psychological pressure every time the roll is changed, which in turn affects the safety and stability of the overall production environment.

[0013] In a possible implementation manner, the roller moving component includes a roller driving member and a roller guide rail.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] In the battery industry, the research and development and application of pole piece reel changing systems are receiving more and more attention. The existing technology generally adopts a manual reel changing method, where operators manually connect and alternate between new and old reels. Although this method meets production needs to a certain extent, the production efficiency is significantly limited due to the cumbersome operation process and high skill requirements for operators. In addition, during the manual operation process, it is easy for the pole piece position to be inaccurate or the tape to be loosely bonded, thus affecting the quality of the final product.

[0046] The existing manual roll-changing method still has certain potential safety hazards. In specific operations, the direct contact between the tape and the pole piece may pose risks such as electric shock and injury to the operator, and in severe cases, even lead to safety accidents. This not only affects the smoothness of production but also subjects the operator to significant psychological pressure during each roll change, thereby affecting the safety and stability of the overall production environment.

[0047] Based on this, referring to Figures 1 to 8 As shown, an embodiment of the present invention provides a pole piece roll-changing system 10, which includes a frame 100, a roll device 200, a glue-opening roller glue-preparing device, and an exchange belt glue-preparing device; the frame 100 has a first side 110 and a second side 120 that are oppositely arranged; the roll device 200 is movably connected to the frame 100, and the roll device 200 includes a first mounting component for mounting a first roll 210 and a second mounting component for mounting a second roll 220, and the first mounting component and the second roll mounting component are arranged on the first side 110; the glue-opening roller glue-preparing device is arranged on the second side 120; the glue-opening roller glue-preparing device includes a glue-opening roller device 300 and a glue-opening roller glue-preparing device 400, the glue-opening roller glue-preparing device 400 can move to the first side 110, and the glue-opening roller glue-preparing device 400 is used for setting an adhesive film on the glue-opening roller device 300, and the glue-opening roller device 300 is used for bonding the pole piece on the second roll 220 through the adhesive film and pulling the pole piece towards the first roll 210; the exchange belt glue-preparing device is arranged on the second side 120; the exchange belt glue-preparing device includes an exchange belt device 500 and an exchange belt glue-preparing device 600, the exchange belt device 500 can move to the first side 110, and the exchange belt device 500 is used for pasting and fixing two pole pieces with an exchange belt film, the exchange belt glue-preparing device 600 can move to the first side 110, and the exchange belt glue-preparing device 600 is used for setting the exchange belt film on the exchange belt device 500.

[0048] In the pole piece roll-changing system 10 of this embodiment, by setting the glue-opening roller glue-preparing device and the exchange belt glue-preparing device to cooperate with the roll device 200, automatic roll-changing operations can be realized. Through the structural design of the frame 100 and the equipped roll device 200, efficient management of the first roll 210 and the second roll 220 is achieved. Compared with the traditional manual roll-changing method, the skills required of the operator are significantly reduced during the pole piece roll-changing process in this system, thereby improving production efficiency. The automated design reduces the complexity of manual operations, ensures that the pole piece is replaced in a shorter time, and thus improves the working efficiency of the overall production line.

[0049] Secondly, the system introduces a rubber - preparing device for the gluing roller and a rubber - preparing device for the exchange belt. These two technological innovations effectively solve the problems of inaccurate pole - piece position and insecure tape bonding caused by manual operation in the existing technology. Specifically, the gluing - roller device 300, in cooperation with the bonding film, can accurately bond the new material to the designated position of the old material roll, ensuring the accurate docking of the pole pieces. At the same time, the exchange - belt device 500 ensures the firm connection between the new and old material rolls through the fixation of the exchange - belt film, reducing the defective - product rate caused by unstable joints.

[0050] Furthermore, the pole - piece roll - changing system 10 of this embodiment greatly improves the safety of the roll - changing process. In the traditional manual method, operators face potential risks of electric shock and injury, while the automated operation of this system reduces the direct contact between personnel and high - voltage components, effectively reducing potential safety hazards.

[0051] In addition, by separately arranging the rubber - preparing device for the gluing roller and the rubber - preparing device for the exchange belt on the second side 120 and the first side 110 of the frame 100 respectively, the pole - piece roll - changing system 10 achieves an efficient and streamlined structural layout in design. When there is no need to perform roll - changing operations, the arrangements of the rubber - preparing device for the gluing roller and the rubber - preparing device for the exchange belt will not cause any interference to the normal operation of the material - roll device 200. This design scheme not only makes full use of the space of the frame 100 but also ensures the functional independence between various devices, thereby improving the overall working efficiency of the system.

[0052] In specific implementation, the configurations of the rubber - preparing device for the gluing roller and the rubber - preparing device for the exchange belt are located in different operation areas, enabling the material - roll device 200 to operate independently without being affected by other devices during regular production activities. For example, the rubber - preparing device for the gluing roller is arranged on the second side 120, and the space and conditions required for its operation are concentrated here, ensuring that it will not form any physical obstacles to the material - roll device 200 on the first side 110 when performing the gluing operation. Similarly, the rubber - preparing device for the exchange belt can also operate stably according to this layout, ensuring the smooth progress of the bonding operation between the pole pieces.

[0053] This design brings about the compactness of the structure, reducing unnecessary equipment overlap and space waste. The compact structure not only optimizes the layout of the equipment, improves the space utilization rate of the workplace, but also reduces the potential risk of interference between devices, contributing to ensuring the smooth progress of the production process.

[0054] Furthermore, the pole - piece roll - changing system 10 further includes a roller - moving device 700. The roller - moving device 700 is movably connected to the frame 100 and is located on the first side 110; at least part of the roller - moving device 700 is located between the gluing - roller device 300 and the second material roll 220, and the roller - moving device 700 is used to press on the pole piece between the second material roll 220 and the gluing - roller device 300.

[0055] In this embodiment, the cooperation between the roller shifting device 700, the glue-applying roller stock preparation device, and the exchange belt stock preparation device greatly optimizes the efficiency of the roll-changing operation through a specific operating principle. Specifically, first, the glue-applying roller stock preparation device completes the bonding of the new material on the second material roll 220 and moves it to a preset position. On this basis, the roller shifting device 700 then moves downward and crimps the new material to ensure that the new and old materials can effectively move to the exchange station. The smooth progress of this process enables the exchange belt stock preparation device to quickly connect the new and old materials, thus effectively completing the roll-changing operation.

[0056] The roller shifting device 700 can crimp the electrode sheet to a preset position while ensuring that the electrode sheet remains taut. This setting effectively avoids the curling of the electrode sheet during the roll-changing process. Curled electrode sheets may lead to a reduction in battery performance due to poor contact during subsequent battery production. Therefore, ensuring the taut state of the electrode sheet is crucial for maintaining the high performance of the battery.

[0057] Specifically, the roller shifting device 700 includes a glue-applying roller 710 and a roller shifting component 720. The glue-applying roller 710 is crimped onto the electrode sheet. The roller shifting component 720 is respectively connected to the frame 100 and the glue-applying roller 710, and the roller shifting component 720 is used to drive the glue-applying roller 710 to move relative to the frame 100 to pull the electrode sheet. The roller shifting device 700 improves the overall operation efficiency and stability of the roll-changing system through an effective structural configuration.

[0058] The crimping function of the glue-applying roller 710 improves the accuracy of the roll-changing process. Its role lies not only in applying appropriate pressure to the electrode sheet but also in preventing the electrode sheet from curling or loosening during the entire operation, thus ensuring good contact performance of the electrode sheet during the battery production process. Specifically, the structure of the glue-applying roller 710 can be made of materials with high strength and good wear resistance, such as aluminum alloy or engineering plastics. The use of these materials can effectively extend the service life of the glue-applying roller 710 and improve its durability in high-frequency operations.

[0059] On the other hand, the design of the roller shifting component 720 aims to ensure the flexible movement of the glue-applying roller 710. The roller shifting component 720 is structurally fixed between the frame 100 and the glue-applying roller 710. This configuration enables the glue-applying roller 710 to move smoothly relative to the frame 100, thereby achieving precise pulling of the electrode sheet. Specifically, the roller shifting component 720 can adopt a motor drive method, combined with a gear system or a slide rail design, to ensure that the glue-applying roller 710 can move smoothly on a predetermined path.

[0060] The roller moving assembly 720 can not only drive the debonding roller 710 to press against the pole piece, but also move the debonding roller 710 up and down or left and right. This multi-directional movement ability makes the pole piece more flexible during the roll change process and can adapt to the requirements of pole pieces of different models and specifications.

[0061] In addition, to improve the reliability of the roller device 700, a feedback control system can be added in the design to monitor the pressing state and displacement of the debonding roller 710 in a timely manner. This feedback system can detect the contact pressure between the debonding roller 710 and the pole piece in real time through sensors and automatically adjust the driving force of the roller moving assembly 720 according to the feedback information, so as to ensure a high contact efficiency under different working conditions.

[0062] In one embodiment, the roller device 700 further includes a roller mounting frame 730. The number of debonding rollers 710 is multiple. The roller mounting frame 730 is slidably connected to the frame 100 and connected to the output end of the roller moving assembly 720. The multiple debonding rollers 710 are spaced on the roller mounting frame 730, and at least part of the multiple debonding rollers 710 press against at least one side of the pole piece. The roller moving assembly 720 is used to drive the roller mounting frame 730 to move relative to the frame 100. This design ensures the free movement of the roller mounting frame 730 and also provides good support for the function of the debonding roller 710.

[0063] The multiple debonding rollers 710 are spaced on the roller mounting frame 730. Such an arrangement not only increases the pressing area of the pole piece but also improves the overall pressing stability. Specifically, the number of the multiple debonding rollers 710 can be two, three or more. Setting multiple debonding rollers 710 can significantly improve the supporting force for the pole piece and the ability to apply pressure evenly, ensure that the pole piece always maintains a stable shape and position during the processing, and reduce the quality risks that may be brought by uneven pressure.

[0064] The roller moving assembly 720 is used to drive the roller mounting frame 730 to move relative to the frame 100. The roller moving assembly 720 can accurately control the movement of the roller mounting frame 730 by mechanical means, so as to drive the multiple debonding rollers 710 to move simultaneously. This design optimizes the operation convenience, eliminates the need to manually adjust the position of the debonding roller 710 during each roll change, and greatly improves the operation efficiency. The sliding design of the mounting frame 730 can also adopt forms such as guide rails or pulleys to make the movement smoother and reduce wear.

[0065] In addition, the connection design of the roller moving mount 730 can also remove or add multiple unsealing rollers 710 according to actual needs to adapt to different production requirements. When a larger crimping area is required during production, the number of unsealing rollers 710 can be easily increased to achieve the ideal effect. When the type or thickness of the electrode tab changes, the roller moving mount 730 can flexibly adjust the number and position of the unsealing rollers 710 to adapt to the new production requirements.

[0066] Specifically, the roller moving assembly 720 includes a roller driving member 721 and a roller guide rail 722. The roller moving mount 730 is slidably connected to the frame 100 through the roller guide rail 722, and the roller guide rail 722 is disposed at an angle with respect to the direction from the first coil 210 towards the second coil 220. The roller driving member 721 is disposed on the frame 100 and connected to the roller moving mount 730, and the roller driving member 721 is used to drive the roller moving mount 730 to move relative to the frame 100.

[0067] This design makes full use of the low-friction characteristics of the guide rail to ensure the smoothness and stability of the roller moving mount 730 during movement. This arrangement not only avoids the possible jitter of multiple unsealing rollers 710 during the coil change process, but also improves the operation accuracy, further ensuring the shape and quality of the electrode tab during the transformation process.

[0068] The roller guide rail 722 is disposed at an angle with respect to the direction from the first coil 210 towards the second coil 220. This design takes into account the requirements for the crimping position of the electrode tab changing system 10 under different working conditions. By adjusting the change of the angle, the crimping position of the unsealing rollers 710 can be flexibly changed, so as to adapt to different specifications of electrode tabs and ensure that the electrode tabs can be pulled or replaced efficiently and evenly. When the angle is larger, it may be beneficial to better handle thicker electrode tabs, while when the angle is reduced, it helps to process thinner electrode tabs. The specific angle can be adjusted according to the actual design requirements, and even can be designed as an adjustable structure to meet the flexible needs of different production links.

[0069] The roller driving member 721 is disposed on the frame 100 and connected to the roller moving mount 730, and is responsible for driving the roller moving mount 730 to move relative to the frame 100. The setting of this driving member ensures that the unsealing rollers 710 can accurately crimp the electrode tab at the required position, so as to maintain a stable tension and position during the coil change process. Specifically, the roller driving member 721 can be a linear cylinder. This choice can not only provide sufficient force to ensure the crimping effect of the unsealing rollers 710, but also achieve rapid repeated positioning to adapt to the frequent coil change operations in production. The linear cylinder has high energy efficiency and response speed during driving, and its structure is simple and easy to maintain, which is suitable for long-term and high-frequency industrial applications.

[0070] Further, the glue separating roller device 300 includes a glue roller mounting frame 310, a glue separating roller assembly 320, and a glue roller guiding roller 360. The glue separating roller assembly 320 is rotatably connected to the glue roller mounting frame 310, and the glue roller guiding roller 360 is connected to the glue roller mounting frame 310. The glue roller guiding roller 360 is spaced apart from the glue separating roller assembly 320. The glue roller guiding roller 360 and the glue separating roller assembly 320 are used to respectively press against opposite sides of the adhesive film and / or the pole piece.

[0071] The design of this structure ensures that the glue roller guiding roller 360 and the glue separating roller assembly 320 can symmetrically press against opposite sides of the adhesive film and the pole piece respectively, thereby maintaining the stability of the material throughout the bonding and processing process.

[0072] By setting the coordinated cooperation between the glue roller guiding roller 360 and the glue separating roller assembly 320, when the roller moving device 700 presses against the pole piece, the glue roller guiding roller 360 can exert an effective limiting and guiding effect on the pressing position of the pole piece. Specifically, the glue roller guiding roller 360 can prevent the pole piece from being overly wound on the glue separating roller assembly 320 due to excessive tension applied, thereby protecting the glue roller assembly 320 from damage. At the same time, this design ensures that the pole piece can always be maintained in an ideal working position during the pasting process, avoiding the situation of poor bonding effect caused by uneven materials, thus achieving high-quality pasting.

[0073] On the other hand, the ingenious design of the glue roller mounting frame 310 and the glue separating roller assembly 320 enables the glue separating roller to rotate efficiently during use, thereby reducing the energy loss caused by friction and achieving rapid pasting of the material. At the same time, the rotation speed of the glue separating roller assembly 320 can be adjusted according to actual needs to achieve the best working state in different production environments. In one embodiment, the number of roller moving devices 700 is two groups. The two groups of roller moving devices 700 are arranged between the first material roll 210 and the second material roll 220, and the two groups of roller moving devices 700 are symmetrically arranged and respectively used to press against the pole pieces on the first material roll 210 and the second material roll 220.

[0074] Through such a design, the roller moving device 700 not only improves the flexibility and adaptability of the production line, but also effectively guarantees the processing efficiency and bonding quality of the pole piece.

[0075] Specifically, by setting two groups of roller moving devices 700, precise pressing operations can be performed on the pole pieces on the first material roll 210 and the second material roll 220 respectively according to production requirements to achieve a more complex production process. In practical applications, differential processing of materials can be realized. For example, for pole pieces of different models or materials of different thicknesses, using two groups of roller moving devices 700 can achieve more intelligent production control. This ability can significantly improve the operational flexibility of the production line when facing diverse product requirements.

[0076] It should be noted that the number of sets of the roller shifting device 700 can be two sets, one set or multiple sets, which is specifically determined according to actual design requirements. If multiple sets of the roller shifting device 700 are designed, a more efficient process flow can be achieved during production.

[0077] Furthermore, the coil device 200 further includes a color mark sensor, which is connected to the frame 100 and is used to sense the pole piece.

[0078] In this embodiment, the design of introducing the color mark sensor into the coil device 200 not only improves the accuracy of pole piece position monitoring, but also enhances the degree of automation of the production process. The color mark sensor is connected to the frame 100 and can monitor the position signals of the pole pieces on the first coil 210 and / or the second coil 220 in real time. The implementation principle of this design is that by identifying specific colors or patterns on the surface of the pole piece, the color mark sensor can quickly and accurately feedback the current positioning state of the pole piece.

[0079] Specifically, the color mark sensor can use a variety of technical means for position detection, such as using photoelectric sensors, CCD cameras or laser rangefinders, etc. The photoelectric sensor emits and receives light to identify the presence or absence of an object, while the CCD camera can perform more complex image processing to identify various features on the pole piece. The laser rangefinder can provide high-precision distance measurement to ensure that the pole piece always maintains an accurate position during production. The combination of these technical means will help improve the stability and reliability of the production process.

[0080] The position signals obtained by the color mark sensor not only provide real-time data support for subsequent process flows, but also can greatly reduce human intervention during production and reduce the probability of operation errors. At the same time, the data feedback of the position signals can be used to adjust the working state of the roller shifting device 700 to ensure that the crimping operation is carried out with optimal parameters. This closed-loop control design enables the production process to adapt to changes in different types of pole pieces and improves the flexibility and response ability of production.

[0081] In addition, adding the color mark sensor also brings various implementation effects. For example, the response time of the sensor is short, enabling rapid position feedback, thereby timely adjusting the operating state of the equipment. When the color mark sensor detects a deviation in the position of the pole piece, it can automatically send a signal to trigger the corresponding adjustment mechanism and quickly restore the pole piece to the preset position to ensure the consistency of product quality.

[0082] Specifically, the color mark sensor includes a first color mark sensor 240 and a second color mark sensor 250. The first color mark sensor 240 is correspondingly arranged with the first coil 210, and the second color mark sensor 250 is correspondingly arranged with the second coil 220.

[0083] This layout design enables each group of coil materials to be equipped with an independent sensor, effectively improving the detection accuracy of the system for the position of the pole piece. In this embodiment, the first color mark sensor 240 is specifically used to sense the pole piece on the first coil material 210 and can monitor the specific position and state of the pole piece in real time; while the second color mark sensor 250 is responsible for sensing the pole piece on the second coil material 220, thus realizing the comprehensive monitoring of the double-coil working state. This dual-sensor configuration not only provides exclusive monitoring channels but also greatly reduces the problem of position recognition errors caused by the mutual interference of the two groups of pole pieces. When the first coil material 210 and the second coil material 220 are running simultaneously, the cooperation between the two sensors can ensure the accurate tracking of the positions of their respective pole pieces, thereby stabilizing the production process.

[0084] By independently setting the first color mark sensor 240 and the second color mark sensor 250, not only can the detection accuracy be significantly improved, but the degree of automation can also be enhanced. The color mark sensor has a fast action response speed and can obtain position signals in real time and provide feedback during the dynamic movement of the pole piece. This enables the system to respond quickly, automatically correct any deviation, and thus greatly enhances the reliability and adaptability. For example, when the first color mark sensor 240 detects a position deviation of the pole piece on the first coil material 210, the system can immediately send a signal to adjust the working state of the roller shifting device 700 to ensure that the pole piece can return to the set position. This closed-loop control mechanism realizes the instant adjustment of the pole piece position and improves the automation and intelligent level of production.

[0085] In addition, in terms of specific implementation, the first color mark sensor 240 and the second color mark sensor 250 can be different types of devices such as photoelectric sensors or image processing sensors. The selection of the appropriate sensor type depends on the production environment and the characteristics of the pole piece. Photoelectric sensors usually have the advantages of fast response and small volume, while image processing sensors can provide higher accuracy and more complex information analysis capabilities. The flexible selection of different sensors enables the overall monitoring system to adapt to various production requirements and provides effective support for pole pieces of different materials, thicknesses, or designs.

[0086] It should be noted that the coil material device 200 usually includes a coil material driving part 230, and a power connection is established between the coil material driving part 230 and the first coil material 210 and / or the second coil material 220. Through this connection, the coil material driving part 230 can actively drive the first coil material 210 and / or the second coil material 220, thereby realizing the automated coil material function and improving the efficiency and stability of the pole piece coil changing system 10 during the production process.

[0087] Specifically, the coil driving member 230 can adopt various typical power sources such as an electric motor, a pneumatic device or a hydraulic device. These power sources can be connected to the first coil 210 and the second coil 220 through appropriate transmission devices such as gears, belts or chains, and then transmit the power to the coiling device. Such a configuration enables the first coil 210 and the second coil 220 to achieve efficient and stable coiling actions during operation, thereby improving the output quality of the electrode sheet under low-tension conditions.

[0088] In addition, in some specific embodiments, the first coil 210 and the second coil 220 can also be driven by passive power. In this case, other power mechanisms of the electrode sheet coil changing system 10 can be directly driven by an external power source or components inside the system, such as rotating the electrode sheet through gravity or friction, thereby driving the operation of the coiling device 200. This setting can reduce the design cost and complexity in some application scenarios, making the system configuration more concise. In this case, the setting of the coil driving member can be selectively retained or cancelled according to actual needs, so as to flexibly meet the requirements under different production conditions.

[0089] It should be noted that the configuration of the coil driving member 230 is not limited to one form. Specifically, according to different manufacturing processes, an appropriate driving scheme can be selected, including but not limited to electric drive, pneumatic drive or hydraulic drive. For example, electric drive has the advantages of being simple and easy to control and can achieve precise coiling control, while pneumatic drive has the characteristic of rapid response and is suitable for high-frequency coiling operations. Hydraulic drive is suitable when large torque is required and can provide stronger power support. These selections can be appropriately adjusted according to changes in production requirements, so there is no unique limitation in specific implementation.

[0090] Through this flexible driving method, the electrode sheet coil changing system 10 has higher adaptability in design, enabling it to better cope with various changes in production environments and requirements, thereby continuously promoting the improvement of production efficiency and the stability of product quality.

[0091] In one embodiment, the rubber roller uncoiling assembly 420 includes a rubber roller uncoiling roller and a rubber roller uncoiling driving member. The rubber roller uncoiling roller is used to support the bonding film between the rubber roller stock preparation tray 410 and the rubber roller glue feeding assembly 430. The rubber roller uncoiling driving member is arranged on the frame 100, and the rubber roller uncoiling roller is connected to the output end of the rubber roller uncoiling driving member. The rubber roller uncoiling driving member is used to drive the rubber roller uncoiling roller to move in a direction perpendicular to the bonding film.

[0092] By starting the rubber roller unwinding drive, the effective driving of the rubber roller unwinding roller can be realized, enabling it to move relative to the frame 100. This movement process enables the rubber roller unwinding roller to effectively press and bond at least one side of the adhesive film, thereby smoothly unwinding the film from the rubber roller glue preparation tray 410 and conveying it to the rubber roller glue feeding assembly 430. This design not only simplifies the manual operation steps but also improves the stability and accuracy of the conveyance of the adhesive film, thus further enhancing the overall production efficiency.

[0093] In addition, the movement trajectory and force of the rubber roller unwinding roller can be adjusted according to different film materials and thicknesses to adapt to various types of adhesive films. This adaptive ability enables the glue preparation device 400 of the unwinding roller to exhibit good flexibility when processing different specifications of films. For example, if the used adhesive film is relatively thin, the rubber roller unwinding drive can control the rubber roller unwinding roller to provide an appropriate pressing force to avoid breakage or wrinkles of the film during transmission, while when processing a thicker film, the pressing force can be increased to ensure smooth unwinding of the film.

[0094] Through this series of automated operations, the glue preparation device 400 of the unwinding roller can achieve an efficient automated glue preparation function, thereby greatly enhancing the production efficiency during the winding process of the battery cell. In this system, the adhesive film is smoothly conveyed to the unwinding roller device 300 in a stable and continuous manner, achieving good bonding between the electrode sheet and the film, and ensuring further improvement in the performance and quality of the battery.

[0095] Specifically, the rubber roller unwinding assembly 420 further includes a rubber roller unwinding frame, which is movably connected to the frame 100 and is connected to the output end of the rubber roller unwinding drive. The rubber roller unwinding drive is used to drive the rubber roller unwinding frame to move relative to the frame 100. This structure enables the rubber roller unwinding drive to effectively drive the rubber roller unwinding frame to move on the frame 100, thereby flexibly adjusting the specific position of the rubber roller unwinding roller to adapt to adhesive films of different thicknesses and materials.

[0096] The number of rubber roller unwinding rollers is multiple. The multiple rubber roller unwinding rollers are rotatably connected to the rubber roller unwinding frame, and the multiple rubber roller unwinding rollers are arranged in parallel and at intervals and press against at least one side of the adhesive film. The configuration of the multiple rubber roller unwinding rollers can not only improve the bearing capacity of the adhesive film but also provide a more uniform pressure during the operation, thereby effectively preventing the film from curling or misaligning and ensuring the stability of the film during conveyance.

[0097] By arranging multiple rubber roller uncoilers, the rubber roller uncoiling driving member can drive these rubber roller uncoilers simultaneously. When the rubber roller uncoiling driving member is started, the multiple rubber roller uncoilers move in a coordinated manner, which significantly improves the stability and operation efficiency of the rubber roller uncoiling assembly 420 for conveying the adhesive film. Compared with the traditional single rubber roller design, this multi-rubber roller linkage method increases the support range of the rubber roller uncoiling assembly 420, enabling the equipment to flexibly respond and adjust the required pressing force and position angle when facing different specifications and types of films.

[0098] It should be noted that the number of rubber roller uncoilers can be two, three or more than four, depending on the actual application requirements and the characteristics of the adhesive film. This flexible design provides multiple options, making the equipment more adaptable in different production environments. For example, when processing a thicker adhesive film, increasing the number of rubber roller uncoilers can provide a larger pressing area and a more uniform pressing effect, thereby reducing the failure rate during operation; while when processing a thinner adhesive film, the number of rubber roller uncoilers can be reduced to avoid problems such as film damage or deformation caused by excessive pressing.

[0099] Specifically, the rubber roller uncoiling driving member can be a linear cylinder. The use of a linear cylinder enables the rubber roller uncoiling assembly 420 to provide strong and fast movement capabilities when driving the rubber roller uncoiling frame to move. The linear cylinder is propelled by compressed air and has a high response speed and good control accuracy during the process of pushing the rubber roller uncoiling frame to move to the side of the rubber roller uncoiler. In this way, the clamping and releasing actions of the rubber roller clamping mechanism on the adhesive film can be effectively controlled to ensure the smooth conveyance of the adhesive film. In addition, another important advantage of selecting a linear cylinder as the driving member is its relatively simple structure, which is convenient for maintenance. Most of the internal structures of the cylinder adopt a modular design, making it more convenient to use and repair, and reducing the failure rate caused by mechanical wear.

[0100] In an embodiment, the rubber roller adhesive feeding assembly 430 includes a rubber roller adhesive feeding frame, a rubber roller adhesive feeding driving member, and a rubber roller clamping mechanism. The rubber roller adhesive feeding driving member is arranged on the machine frame 100. The rubber roller adhesive feeding frame is movably connected to the machine frame 100, and the rubber roller adhesive feeding frame is connected to the output end of the rubber roller adhesive feeding driving member. The rubber roller clamping mechanism is connected to the rubber roller adhesive feeding frame, and the rubber roller clamping mechanism is used to convey the adhesive film to the glue opening roller device 300.

[0101] This design allows the rubber roller glue feeding rack to move flexibly during operation, providing the necessary spatial movement for subsequent film feeding. The output end of the rubber roller glue feeding rack is connected to the rubber roller glue feeding driving member, enabling the driving member to directly control the movement of the rubber roller glue feeding rack. When the rubber roller glue feeding driving member is activated, the rubber roller glue feeding rack moves along a predetermined path, driving the rubber roller glue clamping mechanism to move towards or away from the rubber roller device 300 accordingly. This movement mechanism ensures the precise feeding of the adhesive film, enabling it to reach the rubber roller device 300 smoothly and meet the winding requirements of the battery core.

[0102] The unique function of the rubber roller glue clamping mechanism is that it can effectively clamp the adhesive film conveyed by the rubber roller unwinding assembly 420 and release it quickly when needed. This clamping and releasing mechanism provides flexible control for the gluing process, enabling operators to adjust the handling method of the adhesive film in a timely manner during different production processes. Specifically, the rubber roller glue clamping mechanism can not only capture and fix the movement of the adhesive film but also ensure that the film remains in a stable state through effective clamping force, preventing film damage or position deviation caused by improper movement.

[0103] Through this design of the rubber roller glue clamping mechanism, the working efficiency of the entire rubber roller glue feeding assembly 430 is greatly improved, and its control over the feeding of the adhesive film is precise and flexible. This automated glue clamping mechanism not only simplifies the cumbersome steps of manual operation but also effectively reduces errors caused by human factors, thus ensuring the bonding quality between the adhesive film and the pole piece.

[0104] Specifically, the rubber roller glue feeding driving member can be a linear cylinder. The main role of the linear cylinder in this application is to provide power for the rubber roller glue feeding rack, ensuring that it can move flexibly along a predetermined trajectory. Since the linear cylinder uses compressed air as the power source, it can achieve rapid movement in a short time and has a good response speed, which is crucial for the rapid feeding of the adhesive film. The advantage of using a linear cylinder is that its structure is relatively simple, and installation and maintenance are convenient. The modular design of the cylinder makes replacement and maintenance quick, effectively reducing the failure rate of the equipment after long-term operation.

[0105] Specifically, the rubber roller glue clamping mechanism includes a first clamping plate, a second clamping plate, and a clamping plate driving member. The first clamping plate and the clamping plate driving member are respectively connected to the rubber roller glue feeding rack. The second clamping plate is movably connected to the rubber roller glue feeding rack and connected to the output end of the clamping plate driving member. The adhesive film is at least partially accommodated between the first clamping plate and the second clamping plate. The clamping plate driving member is used to drive the second clamping plate to move towards or away from the first clamping plate to clamp, fix, or release the adhesive film.

[0106] Such a design allows the second splint to effectively move towards or away from the first splint under the control of the splint driving member, thereby realizing the clamping and releasing of the adhesive film.

[0107] By starting the splint driving member, the second splint can accurately approach or move away from the first splint, enabling the film clamping mechanism to accommodate the adhesive film between the two splints. During the clamping process, the adhesive film is clamped and fixed by the first splint and the second splint, ensuring the stability and accuracy of the film during transportation; during release, the second splint moves away from the first splint, allowing the clamped film to be smoothly released, thus enabling the production process to proceed efficiently. Therefore, the design of this mechanism effectively provides the necessary flexibility and convenience for the transportation and processing of the film.

[0108] The function of the splint driving member is crucial, and a cylinder can be selected as the driving method. This design enables the splint driving member to quickly and efficiently perform the clamping and releasing actions under the action of the pneumatic system. The cylinder can provide a strong clamping force in a short time and has good dynamic response characteristics. By adjusting the air source pressure, the clamping force can be adaptively adjusted for different types of adhesive films. Specifically, the type of cylinder can be determined according to the actual application requirements to adapt to different working environments and ensure the stability and safety of the clamping process.

[0109] The structural design of the rubber roller film clamping mechanism is simple and efficient, enabling the entire system to quickly adapt to the requirements of different types of adhesive films during operation. This mechanism not only improves the stability of the adhesive film during transportation, avoiding film slippage or damage caused by improper clamping, but also simplifies the operation steps, reduces the dependence on manual intervention, and thus improves the production efficiency and the overall intelligent level of the production line. In addition, the design driven by the cylinder also reduces the wear of mechanical components and extends the service life of the equipment.

[0110] Specifically, the rubber roller film feeding assembly 430 further includes a rubber roller film feeding pressure roller. The rubber roller film feeding pressure roller includes a film feeding pressure roller body and a film feeding pressure roller driving member. The film feeding pressure roller body is movably connected to the frame 100 and connected to the output end of the film feeding pressure roller driving member. The film feeding pressure roller driving member is disposed on the frame 100, and the film feeding pressure roller body is used to press against one side of the adhesive film away from the rubber roller device 300. The film feeding pressure roller driving member is used to drive the film feeding pressure roller body to move towards or away from the rubber roller device 300.

[0111] With such a structural design, the glue feeding pressure roller driving member can flexibly drive the glue feeding pressure roller body to move towards or away from the glue roller device 300, so as to effectively press the bonding film. By setting the glue roller and the glue feeding pressure roller to press the bonding film, uniform pressure can be provided for the film during the conveying process, which is of great significance for improving the conveying stability of the bonding film. A stable conveying process can not only reduce the risk of sliding or twisting of the film during the conveying process, but also maintain the flatness of the film, ensuring the smooth progress of subsequent processing steps. In addition, when the bonding film passes through the glue roller device 300, the glue roller and the glue feeding pressure roller can also fully flatten the film, improve the surface state of the film, and contribute to improving the bonding effect and the overall quality of the product.

[0112] When the glue feeding pressure roller driving member is started, it can quickly drive the glue feeding pressure roller body to move towards or away from the glue roller device 300, so as to clamp or loosen the bonding film. Specifically, when the glue feeding pressure roller body presses on the side of the bonding film away from the glue roller device 300, the bonding film will be effectively pressed on the glue roller device 300, ensuring a good fitting state between the film and the contact surface, preventing displacement during subsequent operations, and thus improving the stability during the production process.

[0113] In a preferred embodiment, the surface of the glue feeding pressure roller body is provided with a V-shaped groove, which greatly reduces the contact area between the glue feeding pressure roller body and the bonding film. The advantage of reducing the contact area is that it can improve the crimping stability of the glue feeding pressure roller body and avoid sliding or detachment under high pressure. The concentrated pressure points generated by the V-shaped groove design help to increase the local pressure at the clamping part, thereby optimizing the fixing effect on the bonding film and preventing it from being misaligned or deformed during operation.

[0114] The functionality of the glue feeding pressure roller driving member cannot be ignored. It can choose to use a linear cylinder as the driving method. When the linear cylinder applies a driving force, it can adjust the position of the glue feeding pressure roller body at a relatively fast speed, which is particularly suitable for production environments that require frequent start-stop or adjustment. At the same time, the simple structure of the cylinder is also convenient for maintenance, reducing the risk of failure caused by component wear. In practical applications, parameters such as the diameter and stroke of the cylinder can be adjusted according to specific requirements to adapt to different types and thicknesses of bonding films.

[0115] Specifically, the glue roller glue feeding assembly 430 further includes a glue roller glue feeding cutter, which is arranged on the frame 100 and is used to cut the bonding film between the glue roller glue feeding pressure roller and the glue roller unwinding assembly 420.

[0116] By setting the glue roller glue feeding cutter, this device plays an important role in the entire film conveying process, especially at the critical moment when the film needs to be cut.

[0117] The collaborative work of the rubber roller glue feeding cutter, the rubber roller glue feeding pressure roller and the rubber roller uncoiling assembly 420 can achieve efficient and precise cutting. When the bonding film is wound on the rubber roller device 300, the rubber roller glue feeding cutter can quickly cut the film. The realization of this function not only ensures the accuracy of film cutting, but also reduces the potential errors caused by manual operation, improving production efficiency and product quality.

[0118] Specifically, the design of the rubber roller glue feeding cutter can adopt mechanical induction, blade rotation or pneumatic cutting methods, providing multiple options for film cutting. The cutter type in implementation can be a combined design of a fixed blade and a movable blade, or a single rotary cutter. This diverse cutter design can be selected according to specific production requirements to ensure effective cutting for different types of bonding films and thicknesses.

[0119] In addition, it is allowed to adjust the setting position and cutting depth of the rubber roller glue feeding cutter according to actual design requirements. When selecting the cutting depth, it should be ensured that the bottom plate or other films are not damaged. Specifically, the cutter depth can be set from a few millimeters to several centimeters, and it needs to be appropriately adjusted according to the thickness of the film to achieve the best cutting effect. If the set depth of the cutter is too shallow, it may cause the bonding film not to be completely cut, affecting the smooth progress of subsequent operations; while too deep cutting depth may damage the frame 100 and other equipment, bringing additional costs for equipment maintenance.

[0120] Combined with the rubber roller glue feeding pressure roller and the rubber roller uncoiling assembly 420, the installation position of the rubber roller glue feeding cutter should be optimized in the key area where these components meet. Through appropriate spatial design and arrangement, ensure the smooth progress of the cutting action to reduce friction and unnecessary displacement of the film during cutting. In addition, to further improve the safety and stability of cutting, a protective cover for the cutter can be designed to prevent accidental injuries during operation.

[0121] In an embodiment, the rubber roller glue feeding cutter includes a rubber roller cutter and a rubber roller cutter driving part. The rubber roller cutter driving part is respectively connected to the frame 100 and the rubber roller cutter through a firm connecting mechanism. This design enables the rubber roller cutter driving part to stably and efficiently control the movement of the rubber roller cutter to achieve the cutting of the bonding film.

[0122] Specifically, a linear cylinder can be used as the driving means for the rubber roller cutter. Driven by compressed air, the linear cylinder can quickly and accurately drive the rubber roller cutter to move in a direction close to or away from the rubber roller device 300. This driving method not only has good dynamic response ability, but also can ensure the stability of the cutter during the cutting process with a large clamping force, thus improving the cutting accuracy. At the same time, the structure of the cylinder is relatively simple, which is convenient for maintenance and replacement, reducing the failure rate of the equipment, which is crucial for improving production efficiency.

[0123] Through the reasonable design of the cooperation between the rubber roller cutter and the driving member of the rubber roller cutter, it is ensured that the cutting task can be completed quickly and smoothly when cutting the adhesive film. When the driving member of the rubber roller cutter is activated, the rubber roller cutter quickly approaches the film to be cut, realizing rapid cutting and ensuring that there is no displacement or breakage of the film during the operation. At the same time, the cutting depth and speed of the rubber roller cutter can be adjusted by setting the working pressure and stroke of the cylinder to adapt to the cutting requirements of different types and thicknesses of adhesive films.

[0124] For the specific design of the rubber roller cutter, a combined structure between a fixed blade and a movable blade can be adopted to ensure uniform cutting force during the cutting process. Such a structural design can effectively improve the cutting uniformity, and by selecting various blade materials (such as high-speed steel or ceramic materials), the cutting efficiency can be improved and the service life of the tool can be extended.

[0125] It should be noted that the cutting angle, shape and material of the rubber roller cutter can be changed according to different working conditions to achieve the best cutting effect. For example, the cutter can be designed in a straight shape, a serrated shape or other shapes suitable for specific cutting requirements. An effective cutting design can minimize the burrs generated during the cutting of the film, thus improving the flatness of the film surface and avoiding subsequent operation problems caused by the burrs formed after cutting. In addition, the design of applying lateral pressure to the film during the cutting process is also particularly important to prevent the film from being distorted and deformed during cutting.

[0126] In one embodiment, V-shaped grooves can be provided on the surface of the rubber roller cutter to improve the cutting quality and efficiency. The introduction of the V-shaped groove design aims to optimize the contact surface between the rubber roller cutter and the adhesive film, reduce the frictional resistance during the cutting process, and thus achieve more efficient cutting. This design can not only effectively concentrate the cutting force of the tool, reduce the pushing resistance of the film to the cutter during the cutting process, but also improve the stability of the cutter when pressing the film.

[0127] Specifically, through the geometric shape of the V-shaped groove, the contact area of the cutting tool is effectively reduced, enabling the force to be concentrated on a specific area of the film during cutting. This design significantly improves the cutting efficiency between the cutting tool and the film, allowing the film to be cut quickly and cleanly when passing through the rubber roller cutting tool, reducing the energy and time required for cutting. This is particularly important for high-efficiency production as the processing speed of the adhesive film directly affects the overall efficiency and output of the production line.

[0128] In addition, the V-shaped groove design can effectively reduce material deformation during the cutting process, ensuring that the film maintains its predetermined shape and size during cutting. The cutting tool with a V-shaped groove can generate less stress concentration during cutting, reducing the risk of warping or tearing of the material due to pressure. Furthermore, this cutting edge design can improve the neatness of the film edge, thereby reducing potential problems during subsequent processing and improving the quality and accuracy of the final product.

[0129] Specifically, the glue opening roller device 300 includes a glue opening roller assembly 320, a roller adjusting assembly 340, and a roller blanking assembly 350. The roller adjusting assembly 340 is respectively connected to the frame 100 and the glue opening roller assembly 320, and the roller blanking assembly 350 is connected to the frame 100. The roller adjusting assembly 340 is used to drive the glue opening roller assembly 320 to move in a direction close to or away from the roller blanking assembly 350, and the roller blanking assembly 350 is used to cut the adhesive film and / or the electrode sheet on the glue opening roller assembly 320.

[0130] The main function of the glue opening roller assembly 320 is to wind the adhesive film and effectively bond it to the electrode sheet. Through precise design and control, the glue opening roller assembly 320 can ensure the uniformity of film winding and improve the quality of subsequent bonding. In practical applications, the glue opening roller assembly 320 can handle various types of adhesive films, providing flexible adaptability for different electrode sheets, and thus meeting diverse production requirements. The stability of film transportation and bonding is the key to achieving high-quality products.

[0131] The function of the roller adjusting assembly 340 is to drive the glue opening roller assembly 320 to move in a direction close to or away from the roller blanking assembly 350 to adapt to different stages in the actual production process. When film winding operation is required, a relatively large distance is maintained between the glue opening roller assembly 320 and the roller blanking assembly 350 to facilitate the normal transmission of the film. After the winding task is completed, the roller adjusting assembly 340 drives the glue opening roller assembly 320 to approach the roller blanking assembly 350 to prepare for subsequent cutting and blanking.

[0132] The main function of the rubber roller blanking component 350 is to cut and collect the adhesive film and / or the pole piece on the rubber roller component 320. When the rubber roller component 320 finishes unrolling the film, the rubber roller blanking component 350 can quickly and effectively cut the film or the pole piece, ensuring the efficiency of a series of operations such as film collection. At the same time, the design of this component takes into account the function of collecting the cut film, which can effectively prevent the waste materials at the edges and corners generated during the cutting process of the film, further improving the output rate and reducing the production cost.

[0133] Through the reasonable configuration and coordinated work of the rubber roller device 300, the overall device realizes the functions of automatic rubber preparation and rubber cutting. During the production process, the operation of the equipment can effectively reduce the intervention of manual operations, reduce the occurrence of human errors, and at the same time improve the continuity and stability of production. This highly efficient automatic solution provides an optimized process for the manufacture of battery cells, ensuring good adhesion between the film and the pole piece, thus affecting the performance and quality of the final product.

[0134] In specific implementation, for the design of the rubber roller component 320, the rubber roller adjustment component 340, and the rubber roller blanking component 350, different forms and materials can be used for construction. For example, the rubber roller component 320 can use high-strength composite materials to reduce its own weight and at the same time improve wear resistance; the driving means of the rubber roller adjustment component 340 can be electric or pneumatic, and can be flexibly selected according to the requirements of different production lines; while the rubber roller blanking component 350 can be set as a cutter with multiple cutting methods to adapt to the performance requirements of different adhesive materials.

[0135] In an embodiment, the rubber roller blanking component 350 includes a rubber roller cutting mechanism and a waste box. The rubber roller cutting mechanism and the waste box are arranged on the frame 100, and the rubber roller cutting mechanism is arranged between the waste box and the rubber roller component 320 and is used for cutting the adhesive film and / or the pole piece.

[0136] This design can ensure that during the cutting process, the generated waste materials directly and quickly fall into the waste box, thereby improving the operation efficiency and effectively avoiding material waste and pollution caused by the residue of the film or the pole piece.

[0137] The waste box is arranged at the waste recycling station of the rubber roller device 300, and this station is designed to centrally collect the waste materials generated during the film processing. The design of the waste box is combined with the overall layout of the rubber roller device 300, which can effectively reduce the trouble of the operator during the reprocessing and cleaning processes, improving the coherence and efficiency of the work. At the same time, the capacity and structure of the waste box can be designed to be replaceable, which is convenient for regular emptying during the processing and timely maintaining the cleanliness of the equipment.

[0138] The function of the rubber roller cutting mechanism is to accurately cut the adhesive film and / or the pole piece on the rubber roller opening device 300 to ensure that the edges after cutting are neat and meet the requirements of subsequent processes. In practical applications, the rubber roller cutting mechanism can adopt various cutting methods, such as the configuration of fixed knives or movable knives. The advantage of this design is that fixed knives are suitable for cutting films with uniform thickness and relatively thin thickness, while movable knives are suitable for processing thicker pole pieces. By selecting the appropriate cutting mechanism, the efficiency and accuracy of cutting can be ensured, thereby improving the quality of the finished product.

[0139] During this process, the rubber roller adjustment component 340 plays a key role. Since it can drive the position adjustment of the rubber roller opening component 320, allowing it to move to the preset waste recycling station, the unwinding station for bonding and fixing with the pole piece, or move to the glue preparation station of the rubber roller glue preparation device 400. At the rubber roller glue preparation device 400, the adhesive film is attached to the rubber roller opening component 320 to ensure the smooth progress of the subsequent bonding process of the film.

[0140] Specifically, the rubber roller cutting mechanism includes a waste knife and a waste driving part. The waste driving part is arranged on the frame 100, and the waste knife is connected to the output end of the waste driving part; a rubber roller cutting groove for accommodating the waste knife is opened on the outer wall of the rubber roller opening component 320, and the waste knife is used to move into the rubber roller cutting groove to cut the adhesive film and / or the pole piece.

[0141] To adapt to the movement and operation of the waste knife, a rubber roller cutting groove for accommodating the waste knife is opened on the outer wall of the rubber roller opening component 320. The existence of this groove can effectively guide the movement trajectory of the waste knife and ensure its correct position during the cutting process. The waste knife moves into the rubber roller cutting groove by means of linear motion to cut the adhesive film and / or the pole piece. The advantage of setting the rubber roller cutting groove is that it can not only ensure the accuracy of the cutting effect, but also effectively prevent the waste knife from damaging the rubber roller opening component 320 during the cutting process. This is achieved by effectively controlling the contact area between the waste knife and the rubber roller component through the design of the groove, preventing unnecessary mechanical wear.

[0142] Specifically, starting the waste driving part can drive the waste knife to move relative to the rubber roller opening component 320. When the waste knife contacts the adhesive film and at least partially moves into the rubber roller cutting groove, the cutting operation of the film can be completed. The efficiency and automation characteristics of this process significantly improve the production efficiency. At the same time, the accurate cutting-in and retracting actions of the waste knife reduce the resistance of the tool during the cutting process, making the cutting process smoother, thereby improving the integrity and stability of the film and the pole piece.

[0143] In combination with specific implementation embodiments, a linear cylinder can be selected as the waste material driving member. This type of cylinder has the characteristic of rapid response and can efficiently achieve the movement and operation of the waste material knife. When compressed air is introduced into the cylinder, it can quickly generate a thrust for linear motion, driving the waste material knife to perform corresponding actions, thereby ensuring the timely and efficient completion of the film cutting task. The advantages of the linear cylinder also lie in that its structure is relatively simple, facilitating maintenance and replacement, reducing the failure rate caused by long-term use, and thus improving the reliability of the entire rubber separating roller device 300.

[0144] In addition, for the waste material knife, in addition to the linear cylinder, other driving methods can also be considered, such as electric servo drive or stepper motor drive, to meet the requirements of different cutting speeds and accuracies. Such driving schemes can also be flexibly adjusted according to different material thicknesses and cutting requirements to adapt to various production environments. This diverse driving selection not only improves the adaptability of the equipment but also further ensures the safety and stability of production.

[0145] In one embodiment, the rubber separating roller assembly 320 includes a rubber roller fixing member, a rubber roller movable member, and an opening and closing mechanism. The rubber roller fixing member is connected to the rubber roller adjusting assembly 340, and the opening and closing mechanism is respectively connected to the rubber roller fixing member and the rubber roller movable member, and the opening and closing mechanism is used to drive the rubber roller movable member to separate from the rubber roller fixing member to form a space for accommodating the adhesive film or to clamp the adhesive film.

[0146] The coordinated application among these three enables the entire rubber separating roller assembly 320 to effectively complete process operations such as clamping, winding, and bonding of the film. The rubber roller fixing member is connected to the rubber roller adjusting assembly 340 and is stably fixed in the overall frame of the equipment. Such a design ensures that the rubber roller assembly has good support during operation, which helps to improve the stability of the film during winding and avoid affecting the precise positioning of the film due to vibration or other external factors.

[0147] The opening and closing mechanism is respectively connected to the rubber roller fixing member and the rubber roller movable member and has the function of driving the rubber roller movable member to separate from the rubber roller fixing member. Through the adjustment of the opening and closing mechanism, the rubber roller movable member can form a corresponding gap with the rubber roller fixing member to facilitate the effective clamping of the adhesive film. The purpose of this design is to first form a space suitable for accommodating the adhesive film before starting the rubber roller assembly, laying a foundation for subsequent clamping and winding operations.

[0148] Once the bonding film is moved into this space, the opening and closing mechanism can quickly move the roller moving part towards the roller fixed part to complete the clamping of the bonding film. The speed and precision of this action are crucial for improving production efficiency because it can ensure a continuous film processing process and avoid production interruptions or material waste caused by improper clamping. In addition, the opening and closing mechanism can be designed to be pneumatically, hydraulically, or electrically driven and selected according to actual production requirements to further enhance its operational flexibility and adaptability.

[0149] Specifically, the separation and clamping actions between the roller moving part and the roller fixed part can be achieved by setting an accurate motion control program. This control method can not only improve the clamping stability, ensure the positioning accuracy of the film during processing, but also enhance the operational safety and reduce the risk of misoperation caused by human factors.

[0150] Furthermore, the glue roller device 300 includes a glue roller mounting frame 310 and a glue roller drive assembly 330. Among them, the glue roller mounting frame 310 serves as the mounting carrier for the glue roller assembly 320 and can stably support the connection and movement between the two. The glue roller assembly 320 is rotatably connected to the glue roller mounting frame 310 to ensure that it has sufficient freedom of rotation during operation and can effectively wind the film.

[0151] The glue roller drive assembly 330 is connected to the glue roller mounting frame 310. Its main function is to drive the glue roller assembly 320 to rotate and use its movement to help wind the film onto the pole piece. Through this structural design, the glue roller drive assembly 330 can effectively control the rotation speed and direction of the glue roller assembly 320 to achieve fast and accurate winding of the bonding film and ensure its smooth bonding with the pole piece.

[0152] When using the glue roller device 300 of this embodiment, first, the opening and closing mechanism drives the roller moving part and the roller fixed part to separate to form a space for clamping the bonding film. This design enables the opening and closing mechanism to drive the roller moving part towards the roller fixed part again when the bonding film moves into this space during the process operation, thereby effectively maintaining the clamping of the bonding film. This process ensures the stability of the film during clamping, avoids misoperation caused by human factors, and reduces the uncertainty and waste in the production process.

[0153] After picking up the adhesive film, the rubber roller drive assembly 330 plays an important role. It drives the rubber roller assembly 320 to rotate, causing the adhesive film to rotate at least one full circle on its outer wall and ensuring that the adhesive surface of the adhesive film always faces outward. This design not only ensures effective contact between the adhesive film and the electrode sheet but also maximally utilizes the adhesive properties of the adhesive film, thereby effectively enhancing the adhesion effect during the winding process. This automated winding process significantly improves production efficiency while effectively reducing the uncertainties and process defects that may be caused by manual operations.

[0154] Meanwhile, at the moment when the rubber roller assembly 320 contacts the electrode sheet, the adhesive film immediately forms an adhesion with the electrode sheet. This automated processing method significantly reduces unnecessary contact in manual operations, reduces the potential hazards of the electrode sheet coating or the adhesive film to the operators, and improves safety. This has important practical significance for modern industrial production, especially in fields with high-precision requirements such as battery cell manufacturing.

[0155] In addition, for this design, the rubber roller mounting bracket 310 can adopt different materials and structural forms according to actual needs. For example, high-strength aluminum alloy can be used to reduce the overall weight while enhancing its load-bearing capacity; and the rubber roller drive assembly 330 can be configured with various drive methods, such as electric drive, pneumatic drive, etc., to adapt to different production environments and requirements. In a specific implementation, the drive assembly can be adjusted to a motor with a variable speed function so that the rotation speed of the rubber roller assembly can adapt to films of different thicknesses to ensure the best winding effect.

[0156] Through this systematic design, the above-mentioned rubber roller device 300 not only optimizes the overall working process but also improves the operation efficiency and safety in multiple aspects, providing good guarantee for the automated production of battery cells.

[0157] Furthermore, in this embodiment, it is ensured that during the bonding operation, the clamping action of the rubber roller moving part and the rubber roller fixed part can be fast and accurate, reducing the bonding defects caused by errors in materials in manual operation examples. This not only improves the product yield rate but also lays a good foundation for subsequent winding operations. Through the continuous drive of the rubber roller drive assembly 330 on the rubber roller assembly 320, the electrode sheet can also be smoothly wound onto the rubber roller assembly 320 along a preset trajectory, ensuring the smoothness of the process.

[0158] Overall, through the implementation of the above design, the rubber roller device 300 significantly improves the degree of automation during the cell winding process, reduces the need for manual operations, and greatly reduces the operation risks and potential health hazards of workers in production. Compared with the traditional manual unwinding method, the rubber roller device 300 not only simplifies the operation but also greatly improves the safety and efficiency of the production process.

[0159] Specifically, the rubber roller adjustment assembly 340 includes at least one of a rubber roller flipping mechanism, a rubber roller transverse movement mechanism and a rubber roller moving mechanism. The rubber roller flipping mechanism is used to drive the rubber roller assembly 320 to rotate relative to the frame 100, the rubber roller transverse movement mechanism is used to drive the rubber roller assembly 320 to move in a direction parallel to the frame 100, and the rubber roller moving mechanism is used to drive the rubber roller assembly 320 to move in a direction perpendicular to the frame 100.

[0160] By providing the rubber roller flipping mechanism, the rubber roller lateral movement mechanism and the rubber roller moving mechanism, the multi-directional adjustment function of the rubber roller assembly 320 can be effectively realized, and the automation degree of the rubber roller device 300 can be significantly improved. This automated design not only reduces the complexity of manual operation, but also improves the production efficiency of the equipment, and meets the needs of modern industry for flexible automated equipment.

[0161] It is worth noting that the rubber roller flipping mechanism, the rubber roller lateral movement mechanism and the rubber roller moving mechanism can be used separately to independently drive the rubber roller assembly 320. The design of independent operation can meet different operation requirements. For example, in some cases, only the rotation of the rubber roller needs to be adjusted without lateral or vertical movement, or vice versa. Through such flexibility, the operation of the equipment is more efficient and more adaptable, thereby reducing the time cost of maintenance and adjustment.

[0162] In addition, the combined use of the rubber roller flipping mechanism, the rubber roller lateral movement mechanism and the rubber roller moving mechanism also provides greater operational convenience. This combination enables fine adjustment of the rubber roller assembly in complex operations, such as rotation and position movement required simultaneously during the bonding process. Such characteristics greatly enhance the operational flexibility of the rubber roller opening device 300 and meet the requirements for efficient operation in a variety of industrial applications.

[0163] Specifically, the rubber roller turning mechanism includes a rubber roller turning shaft and a rubber roller turning driving member, the rubber roller turning shaft is respectively connected to the rubber roller turning driving member and the rubber roller mounting frame 310, and the rubber roller turning driving member is used to drive the rubber roller mounting frame 310 to rotate relative to the frame 100.

[0164] Specifically, by starting the rubber roller flipping drive, the rubber roller flipping shaft can be quickly driven to rotate, thereby realizing the rotation of the rubber roller mounting frame 310. It should be emphasized that at this time, the rotation axis of the rubber roller flipping shaft is not coaxial with the rotation axis of the rubber roller assembly 320, so that the flipping function of the rubber roller flipping mechanism can be realized.

[0165] The design of the rubber roller flipping drive is flexible and diverse. A combined structure of a drive motor and a belt drive mechanism (or a gear drive mechanism) can be adopted to transfer power to the rubber roller flipping shaft more efficiently. By using a belt drive mechanism, the output power of the drive motor can be effectively transmitted to the rubber roller flipping shaft, realizing the smooth rotation of the rubber roller mounting bracket 310 relative to the machine frame 100.

[0166] In this design, the selection of the drive motor can be optimized according to specific power requirements, speed characteristics, and operating precision. Generally, an AC motor or a DC motor can be selected. The former has advantages in energy conservation and control, while the latter performs better in starting and speed regulation. Therefore, the specific selection of the drive motor should meet the best match between production requirements and the overall equipment performance. In addition, in terms of the transmission mechanism, using a belt drive or a gear drive also has its own advantages and disadvantages. The belt drive has better shock absorption and noise control capabilities and is suitable for occasions where the precision requirement is not particularly high, while the gear drive can achieve higher transmission efficiency and precision.

[0167] Through the design of the rubber roller flipping mechanism, the flexibility and adaptability of the rubber roller opening device 300 can be effectively improved. The rubber roller flipping mechanism provides convenience for adjusting the working angle of the rubber roller opening assembly 320, enabling the rubber roller assembly to be conveniently flipped and adjusted in different production processes to optimize the bonding effect.

[0168] Specifically, the rubber roller transverse movement mechanism includes a rubber roller transverse movement frame and a rubber roller transverse movement drive. The rubber roller transverse movement frame is respectively connected to the rubber roller mounting bracket 310 and the rubber roller transverse movement drive, and the rubber roller transverse movement drive is used to drive the rubber roller transverse movement frame to move along a direction parallel to the machine frame 100.

[0169] This design allows the relative position of the rubber roller to be flexibly adjusted according to the requirements of the production process during operation. By starting the rubber roller transverse movement drive, the rubber roller transverse movement frame can be quickly driven to move along the direction of the machine frame 100, which also drives the corresponding movement of the rubber roller mounting bracket 310, thereby realizing the lateral adjustment function of the rubber roller opening assembly 320. This mechanical structure enables the rubber roller opening equipment to adapt to different process requirements during operation, improving the flexibility and working efficiency of the equipment.

[0170] Specifically, the rubber roller transverse movement drive can adopt a combined structure of a drive motor and a gear drive mechanism. The gear drive mechanism usually includes the combination of a gear and a rack. When the rubber roller movement mechanism is not set, the rack can be fixedly connected to the machine frame 100. When the rubber roller movement mechanism is set, the rack is connected to the rubber roller movement mechanism. The drive motor is connected to the gear through the output end. The meshing relationship between the gear and the rack enables the rubber roller transverse movement frame to move laterally relative to the machine frame 100 when the drive motor is started.

[0171] The advantages of this design are that the gear transmission structure has high transmission efficiency and reliability, can amplify the power output by the motor to varying degrees, and thus achieve higher load capacity and operating precision. At the same time, the flexible design of the fixed connection and movable connection of the rack can be quickly adjusted according to different working states, meeting the requirements of the equipment for high adaptability and high efficiency. For example, in certain specific application scenarios, the moving speed of the rubber roller transverse movement frame needs to respond quickly, and the combination of the gear and the rack can achieve smooth and precise lateral adjustment.

[0172] Specifically, the rubber roller moving mechanism includes a rubber roller moving frame and a rubber roller moving driving member. The rubber roller moving frame is respectively connected to the rubber roller mounting frame 310 and the rubber roller moving driving member. The rubber roller moving driving member is used to drive the rubber roller mounting frame 310 to move in a direction perpendicular to the machine frame 100.

[0173] By starting the rubber roller moving driving member, the rubber roller transverse movement frame can be driven to move relative to the machine frame 100, and this process is also accompanied by the corresponding movement of the rubber roller mounting frame 310. Through this design, the rubber roller assembly 320 can be smoothly moved to the required working position, effectively ensuring the stability and continuity of the processing process. Specifically, the design of the rubber roller moving mechanism not only improves the ability to meet dynamic working requirements, but also takes into account the operation convenience of the machine under different working conditions.

[0174] In terms of technical implementation, the rubber roller moving driving member can adopt a combined structure of a driving motor and a lead screw transmission mechanism. The lead screw transmission mechanism has high transmission precision and load capacity. Its slider is connected to the rubber roller moving frame, and the slider is driven to linearly move along its axis by rotating the lead screw. At the same time, the other end of the lead screw is rotatably connected to the machine frame 100, ensuring that the rubber roller moving frame can move smoothly under the action of the driving motor.

[0175] In one embodiment, the exchange belt device 500 includes an exchange adjustment component 510 and two groups of belt changing components. The exchange adjustment component 510 is used to connect to the external machine frame 100. The two groups of belt changing components are respectively connected to the exchange adjustment component 510. The exchange adjustment component 510 is used to drive the two groups of belt changing components to move towards or away from each other; the belt changing component includes a belt changing suction cup and a spare glue suction cup. The belt changing suction cup is used to adsorb two electrode foils, and the spare glue suction cup is used to adsorb the exchange belt film; the exchange belt spare glue device 600 includes an exchange glue paper disk 610, an exchange spare glue component 620, and an exchange glue pulling component 630. The exchange glue paper disk 610 is used to carry the exchange belt film. The exchange spare glue component 620 is used to convey the exchange belt film to the exchange glue pulling component 630. The exchange glue pulling component 630 is used to pull the exchange belt film to the spare glue suction cup; wherein, the exchange belt device 500 is used to bond the exchange belt film to two electrode foils.

[0176] The tape - changing and glue - applying equipment of this embodiment effectively solves the problems of low operation efficiency and potential safety hazards caused by manual handover of new and old tape materials through its unique structural design and automation functions.

[0177] First of all, the tape - changing device 500 is adopted to achieve automatic glue - applying, significantly improving the tape - changing efficiency in the production process of battery cells. The traditional manual operation method has low production efficiency due to complex disassembly and connection steps, while the equipment of this embodiment can automatically adjust the relative positions of two groups of tape - changing components without manual intervention, thus accelerating the tape - changing process and reducing the operation time.

[0178] Secondly, since the equipment of this embodiment adopts the combined design of tape - changing suction cups and glue - applying suction cups, it greatly reduces the errors and material losses that may be caused by manual operation. The accurate adsorption of the tape - changing suction cups and glue - applying suction cups on the electrode plates and film reduces material damage and waste during the tape - changing process, and also avoids accidental accidents that may occur during the operation of workers, improving safety.

[0179] In addition, the tape - changing and glue - applying component 620 and the tape - changing and glue - pulling component 630 in the equipment enhance the smoothness of film conveyance, making the tape - changing process more stable. This smoothness is particularly important in a high - speed production environment, which can effectively prevent production problems caused by system jitter or film misalignment, thus further improving production stability and consistency.

[0180] Specifically, the tape - changing components include a left tape - changing component 520 and a right tape - changing component 530. The left tape - changing component 520 and the right tape - changing component 530 are symmetrically arranged and are respectively connected to the exchange adjustment component 510. Two electrode plates are located between the left tape - changing component 520 and the right tape - changing component 530;

[0181] The left tape - changing component 520 includes a left tape - changing suction cup and a first glue - applying suction cup. The left tape - changing suction cup is used to adsorb one of the electrode plates, and the first glue - applying suction cup is used to adsorb one of the exchange - tape films; the right tape - changing component 530 includes a right tape - changing suction cup and a second glue - applying suction cup. The right tape - changing suction cup is used to adsorb the other electrode plate, and the second glue - applying suction cup is used to adsorb the other exchange - tape film;

[0182] The tape - changing device 500 further includes an exchange cutting component 540. The exchange cutting component 540 is arranged on the left tape - changing component 520 and / or the right tape - changing component 530, and the exchange cutting component 540 is used to cut the two electrode plates.

[0183] In the tape-changing and glue-applying device of this embodiment, the operation steps are as follows: First, the first glue-applying suction cup and the second glue-applying suction cup respectively adsorb a piece of tape-changing film. Next, two pole pieces are placed between the left tape-changing assembly 520 and the right tape-changing assembly 530. The left tape-changing suction cup and the right tape-changing suction cup respectively adsorb the two pole pieces. Subsequently, the two pole pieces are cut by starting the tape-changing and cutting assembly 540 to ensure that each pole piece is cut evenly and precisely. Finally, the left tape-changing assembly 520 and the right tape-changing assembly 530 respectively connect the tape-changing films from the opposite sides of the two pole pieces, thus completing the entire tape-changing operation.

[0184] This device combines the collaborative work of multiple components, has a high degree of automation, fully improves the efficiency of the tape-changing operation, reduces the need for manual intervention, and also improves the accuracy and safety of pole piece processing. Specifically, the symmetric design of the left tape-changing assembly 520 and the right tape-changing assembly 530 enables the operation to be carried out simultaneously on both sides, thus accelerating the operation process. In addition, the combined setting of the glue-applying suction cup and the tape-changing suction cup improves the adsorption capacity, reduces the risk of damage to the pole piece during the adsorption process, and ensures the quality of the final product.

[0185] In one embodiment, the left tape-changing assembly 520 includes a first left tape-changing suction cup and a second left tape-changing suction cup. The left tape-changing assembly 520 is also provided with a left suction cup mounting bracket and a left suction cup driving member. The first left tape-changing suction cup, the second left tape-changing suction cup, and the first glue-applying suction cup are all connected to the left suction cup mounting bracket. The function of the left suction cup driving member is to drive the left tape-changing suction cup or the first glue-applying suction cup to achieve the corresponding cooperation with the right tape-changing suction cup. At the same time, the right tape-changing assembly 530 also includes a first right tape-changing suction cup and a second right tape-changing suction cup. The right tape-changing assembly 530 is also provided with a right suction cup mounting bracket and a right suction cup driving member. The first right tape-changing suction cup, the second right tape-changing suction cup, and the second glue-applying suction cup are all connected through the right suction cup mounting bracket. The right suction cup driving member is used to drive the right tape-changing suction cup or the second glue-applying suction cup to achieve the corresponding operation with the left tape-changing suction cup.

[0186] The design principle of this embodiment is that after the left suction cup driving member is started, it can drive the left suction cup mounting bracket to drive the left tape-changing suction cup and the first glue-applying suction cup to rotate, thereby effectively adsorbing the pole piece. Specifically, first, the first left tape-changing suction cup and the second left tape-changing suction cup respectively adsorb on the pole piece. As the tape-changing and cutting assembly 540 is started and cuts the pole piece, at this time, the first left tape-changing suction cup and the second left tape-changing suction cup will respectively adsorb the two cut sections of the pole piece.

[0187] Immediately afterwards, the right tape-changing assembly 530 starts to rotate so that the second glue-preparing suction cup forms a corresponding structure with the two sections of pole pieces. At this time, the tape-changing film will be bonded and fixed to the two sections of pole pieces through the second glue-preparing suction cup, thus realizing the preliminary combination of the two sections of pole pieces and the tape-changing film. After one side of the pole piece is successfully bonded with the tape-changing film, the first right tape-changing suction cup and the second right tape-changing suction cup will respectively adsorb the two sections of pole pieces. Subsequently, the left tape-changing assembly 520 will attach another tape-changing film to the other side of the two sections of pole pieces, thus completing the entire tape-changing connection operation.

[0188] The technical effect of this embodiment is that through the coordinated operation of the left tape-changing suction cup and the right tape-changing suction cup, rapid and accurate adsorption and bonding of the pole pieces can be achieved. In addition, the mutual cooperation of the left suction cup driving member and the right suction cup driving member ensures the synchronization and coordination during the adsorption and bonding process, greatly improving the automation level and operation efficiency. By utilizing the mechanical structures of the left suction cup mounting frame and the right suction cup mounting frame, flexible rotation and movement of the pole pieces can be realized, and the stability during the pole piece operation can be ensured.

[0189] In the specific implementation manner, the configuration of the left tape-changing suction cup and the right tape-changing suction cup can be one, two or more than two, and the specific quantity is determined according to the actual design requirements. This design provides flexible operation options and improves the adaptability of the tape-changing operation. In addition, the combination of the first glue-preparing suction cup and the second glue-preparing suction cup combines the glue-preparing function with the adsorption function of the pole pieces, optimizes the overall performance of the equipment, and reduces the complexity in the work process.

[0190] Specifically, the left suction cup driving member and the right suction cup driving member can be designed to use a rotary motor or a rotary cylinder as the power source. A rotary motor is a device that converts electrical energy into mechanical energy, and it has significant advantages in accurately controlling the rotation speed and direction, and can achieve efficient and stable rotation. This driving method is suitable for application scenarios that require precise control of the adsorption action. Especially in the fine operation of the pole pieces, the rotary motor can ensure the accurate positioning of the adsorbed object.

[0191] A rotary cylinder is a mechanical device driven by gas pressure, and its working principle is based on gas compression and release, and realizes the rotation action by rotating the piston inside the cylinder. Compared with a rotary motor, a rotary cylinder has the characteristics of simple operation and rapid response, and is suitable for occasions that require a large torque and rapid response. In some production environments, when the gas source is relatively sufficient and the explosion-proof and protection requirements for the electrical part are relatively high, a rotary cylinder is usually a more ideal choice.

[0192] In terms of specific implementation, the selection of the rotary motor and the rotary cylinder can be reasonably configured according to the actual working conditions and application requirements. For example, in some occasions with high-frequency operation requirements, the rotary motor can provide higher stability and continuity; while in an environment with high efficiency requirements and sufficient air source, the rotary cylinder can demonstrate greater flexibility and convenience. It should be noted that the selection of these two driving methods not only affects the working efficiency of the equipment, but also plays a key role in the automation level of the entire tape-changing operation.

[0193] The operating principle of the tape-changing and glue-applying equipment is as follows: When connecting two pole pieces, first, the first pole piece (old pole piece) and the second pole piece (new pole piece) are moved between the left tape-changing assembly 520 and the right tape-changing assembly 530 to ensure that the subsequent operations can be smoothly carried out within the effective working area of the equipment. Subsequently, the first left tape-changing suction cup and the second left tape-changing suction cup are respectively in close contact with the first pole piece and perform adsorption and fixation. At the same time, the first right tape-changing suction cup and the second right tape-changing suction cup perform the adsorption operation on the second pole piece.

[0194] After the adsorption and fixation are completed, the exchange cutting assembly 540 is started to cut the first pole piece into a first cut section and a second cut section; at the same time, the second pole piece is cut into a third cut section and a fourth cut section. During this process, the first left tape-changing suction cup and the second left tape-changing suction cup will respectively adsorb the first cut section and the second cut section, while the first right tape-changing suction cup and the second right tape-changing suction cup will also firmly adsorb the third cut section and the fourth cut section.

[0195] In the next step, the equipment will extract the second cut section and the third cut section, leaving only the first cut section on the first left tape-changing suction cup and the fourth cut section on the second right tape-changing suction cup. This operation ensures that only the cut sections that need to be bonded remain on the suction cups. Subsequently, the right suction cup driving member is started to drive the right suction cup mounting frame to rotate and align the exchange tape film on the second glue-applying suction cup with one side of the first cut section and the fourth cut section. At this time, the exchange tape film is accurately bonded to the corresponding sides of the first cut section and the fourth cut section.

[0196] Similarly, the left suction cup driving member is also started so that the first glue-applying suction cup rotates towards the other side of the first cut section and the fourth cut section and bonds the exchange tape film to the other side of these two cut sections. Through such an operation, the opposite sides of the first cut section and the fourth cut section are effectively bonded and fixed, thus completing the tape-changing operation. The design of this step is intended to ensure the bonding stability and accuracy during the connection of the pole pieces, so that the connection part has good physical properties in subsequent operations.

[0197] It is worth noting that the efficient execution of the above implementation steps depends on the good coordination of the left belt changing assembly 520 and the right belt changing assembly 530, as well as the stability and operating accuracy of each suction cup drive. In a specific implementation, the number of suction cups can be flexibly adjusted according to actual needs, which may be one, two or more; under specific needs, the designer can choose different types of suction cups, such as rubber suction cups or silicone suction cups, to meet the bonding requirements of different pole piece materials. Such flexibility not only improves the adaptability of the system, but also significantly enhances production efficiency.

[0198] Before the tape exchange operation, the function of the tape exchange glue preparation device 600 is to place the tape exchange film on the first glue preparation suction cup and the second glue preparation suction cup respectively, so as to prepare for the subsequent tape exchange operation. Specifically, the design concept of the tape exchange glue preparation device 600 is based on convenient operation procedures and efficient operation efficiency. In this process, the setting of the first glue preparation suction cup and the second glue preparation suction cup allows the user to quickly load the film without frequently changing the film, which effectively improves the production efficiency.

[0199] The advantage of this configuration is that the use of multiple glue preparation suction cups can handle the gluing preparation work of multiple pole pieces at the same time, significantly reducing the operation time and manpower input. At the same time, through the reasonable design of the mechanical structure, it is ensured that the film can be firmly adsorbed on the suction cup, avoiding errors or reduced efficiency caused by film sliding or falling off during operation. Especially in a large-scale production environment, this design scheme demonstrates its good adaptability and flexibility.

[0200] After that, after the connection is completed, the exchange tape glue preparation device 600 comes into play again, accurately placing the exchange tape film on the first glue preparation sucker and the second glue preparation sucker to prepare for the next exchange tape action. The repeatability and efficiency of this operation show the indispensable importance of this device in the production line. In this way, efficient management and use of liquid adhesives or film bonding materials are achieved, and the overall operating efficiency of the equipment is brought to a new level.

[0201] It should be noted that the number of the first and second glue suction cups is set to two, and the specific number can be adjusted according to actual application requirements. For example, under certain conditions, additional glue suction cups may need to be added. This flexibility enables the equipment to adapt to ever-changing production needs. If only one glue suction cup is set in some cases, the frequency of film replacement may increase, which in turn affects the overall production efficiency and smoothness. Therefore, the setting of the number of suction cups should be weighed according to specific needs during design.

[0202] Specifically, the exchange cutting component 540 includes an exchange cutter and an exchange cutter driving member. The exchange cutter driving member is respectively connected to the right suction cup mounting frame and the exchange cutter to drive the exchange cutter to separate from the left tape-changing component 520. The first right tape-changing self-reel, the second right tape-changing suction cup, and the second glue-preparing suction cup are movably connected to the right suction cup mounting frame.

[0203] During the operation, when the exchange adjustment component 510 drives the left tape-changing component 520 and the right tape-changing component 530 to approach each other, the exchange cutter moves accordingly to complete the cutting of two pieces of pole pieces. This process ensures that the new and old pole pieces can be accurately cut into the required cut segments before bonding, thus realizing the effective cooperation of different pole piece materials.

[0204] After the cutting is completed, the exchange cutter driving member also has the function of moving in the reverse direction, and can drive the first right tape-changing suction cup, the second right tape-changing suction cup, and the second glue-preparing suction cup to return to the initial position. This reset action helps the device to quickly prepare for the next operation after completing one cutting operation, significantly improving the efficiency and continuity of the production process.

[0205] The type of the exchange cutter driving member can be diversified, specifically it can be in various forms such as a cylinder, a spring, etc. As a common driving device, the cylinder uses compressed air for driving, has the advantages of rapid response and stable movement, and is suitable for occasions with frequent operations and high requirements; while the spring is a passive energy storage device, which can achieve automatic reset by virtue of its elasticity, and has a simple structure and high reliability. Selecting a suitable driving member is crucial for improving the cutting efficiency and ensuring the operation stability.

[0206] In a specific implementation, the exchange cutter can have various cutter forms and geometric structures to meet the cutting requirements of different pole piece materials. Its cutter shape can be a straight edge, serrated, etc., and can be specifically selected according to the properties of the material and the cutting requirements. If the cutter shape is inappropriate, it may lead to uneven cutting and affect the subsequent bonding quality. Therefore, the designer should fully consider the matching between the cutter shape and the cutting material to ensure excellent cutting effect.

[0207] The present invention also provides a method for pole piece roll changing, which uses the pole piece roll changing system 10 in any of the above embodiments. The method for pole piece roll changing includes the following steps:

[0208] Step S100, glue-preparing step, the glue-preparing device 400 of the glue-opening roller attaches the bonding film to the glue-opening roller device 300, and the exchange tape glue-preparing device 600 attaches the exchange tape film to the exchange tape device 500;

[0209] Step S200, glue-opening step, the glue-opening roller device 300 moves to the first side 110, and the glue-opening roller device 300 bonds the pole piece on the second material roll 220 and pulls it towards the first material roll 210;

[0210] Step S300, the tape exchange step. The tape exchange device 500 moves to the first side 110, and the tape exchange device 500 connects the pole piece on the first coil 210 and the pole piece on the unsealing roller device 300.

[0211] It can be understood that when the pole piece coil changing method of this embodiment is adopted, by setting the unsealing roller glue preparation equipment and the tape exchange glue preparation equipment to cooperate with the coil device 200, the automatic coil changing operation can be realized. This design makes full use of the structural characteristics of the frame 100 and combines with the efficient management scheme of the coil device 200 to effectively control the first coil 210 and the second coil 220, significantly improving the operation efficiency of the production line.

[0212] Compared with the traditional manual coil changing method, this system significantly reduces the skill requirements of the operators during the pole piece coil changing process, making the operation more convenient, thus improving the overall production efficiency. Due to the automated design, the complexity of manual operation is reduced, ensuring that the pole piece is replaced in a shorter time. This not only improves the production efficiency but also further optimizes the production process and reduces possible errors.

[0213] The introduction of the unsealing roller glue preparation equipment and the tape exchange glue preparation equipment in this embodiment is an important innovation at the technical level. The synergistic effect of these two pieces of equipment effectively solves the problems of inaccurate pole piece position and insecure tape bonding caused by manual operation in the prior art. Specifically, the unsealing roller device 300, in cooperation with the bonding film, can accurately bond the new material to the designated position of the old coil, ensuring the accurate docking of the pole pieces. At the same time, the tape exchange device 500 enhances the connection firmness between the new and old coils through reliable fixation of the tape exchange film, significantly reducing the defective product rate caused by unstable joints. This technical improvement not only improves the bonding efficiency of the pole pieces but also helps to ensure the consistency and reliability of the products.

[0214] In addition, the pole piece coil changing system 10 of this embodiment also has a significant improvement in terms of safety. In the traditional manual coil changing method, the operators face potential risks such as electric shock and injury, while the automated operation mode of this system effectively reduces the direct contact between personnel and high-voltage components, thus significantly reducing safety hazards. The design of this system ensures the personal safety of the operators through the automated process and improves the safety of the overall production environment.
