Description

Technical Field

[0001] This application relates to the field of flexible rewinding of electronic aluminum foil, and in particular to an active control edge cutting device and a flexible rewinding machine for electronic aluminum foil. Background Technology

[0002] Electronic aluminum foil is a key basic material for electronic components. With the high-quality development of the aluminum foil industry for electrolytic capacitors, higher requirements have been placed on the quality control capabilities of high-voltage soft electronic aluminum foil.

[0003] The processing of electronic aluminum foil for electrolytic capacitors includes processes such as melting, casting, milling, homogenization, hot rolling, cold rolling, rewinding, alkaline washing, foil rolling, intermediate unwinding, tension leveling, cleaning, shearing, heat treatment, and rewinding. For details on the rewinding machine and rewinding method, please refer to publication number CN120943028A.

[0004] However, since the raw material for electronic aluminum foil used in electrolytic capacitors is 99.996% high-purity aluminum, and in the traditional soft rewinding method for electronic aluminum foil, the soft finished electronic aluminum foil undergoes a rolling oil cleaning process and a 560-degree high-temperature annealing process before rewinding. Therefore, the end face of the aluminum foil roll is prone to quality defects such as oxidation and misalignment, which seriously affects the corrosion resistance of the electronic aluminum foil and results in a large amount of unqualified electronic aluminum foil waste. Therefore, it is necessary to trim the end face of the soft electronic aluminum foil.

[0005] Traditional edge trimming methods present technical challenges in trimming the ends of soft electronic aluminum foil, including edge curling and scratches. Edge curling occurs at the edge of the aluminum foil during rewinding, where the end face of the coil warps into an arc shape due to the trimming process, affecting the flatness of the foil surface. The cause of edge curling is that after high-temperature heat treatment and annealing, the electronic aluminum foil material softens, and the curved edge of the foil during winding easily leads to compression and curling. Simultaneously, stretching and burrs occur at the cut edges during slitting, causing the foil edges to curl after winding, resulting in a significant increase in electronic aluminum foil waste.

[0006] The aluminum foil edge correction device disclosed in CN113291904A provides a pressure roller and guide roller to eliminate the edge curling phenomenon of aluminum foil and avoid damage to the foil surface, but it lacks application in conjunction with the rewinding process. Summary of the Invention

[0007] Therefore, it is necessary to provide an active control edge cutting device and an electronic aluminum foil soft rewinding machine.

[0022] The pressure rollers work together with the guide rollers of the electronic aluminum foil soft rewinding machine to flatten the aluminum foil;

[0023] The cylinder-driven pressure roller is connected to the rotary pressure roller and is used to adjust the distance between the rotary pressure roller and the guide roller.

[0024] The pressure controller is connected to the pressure roller cylinder and is used to control the output of the pressure roller cylinder to change the pressure of the pressure roller and guide roller on the aluminum foil by adjusting the distance.

[0045] This application discloses an actively controlled edge-cutting device and an electronic aluminum foil flexible rewinding machine, which includes some or all of the technical features of the following embodiments; that is, the actively controlled edge-cutting device and the electronic aluminum foil flexible rewinding machine include some or all of the following structures. In one embodiment of this application, an actively controlled edge-cutting device is applied in an electronic aluminum foil flexible rewinding machine having a winding tension weighing roller and a winding machine. The actively controlled edge-cutting device includes an upper blade holder mechanism and a lower blade shaft mechanism; the upper blade holder mechanism and the lower blade shaft mechanism are both disposed between the winding tension weighing roller and the winding machine, and the upper blade holder mechanism and the lower blade shaft mechanism are disposed opposite to each other to cooperate in cutting the aluminum foil rewound by the electronic aluminum foil flexible rewinding machine; the upper blade holder mechanism is configured above the lower blade shaft mechanism to actively cooperate in cutting in an adjustable manner; the lower blade shaft mechanism is configured to clamp the aluminum foil together with the upper blade holder mechanism and cooperate in cutting on the outer surface of the lower blade shaft mechanism. The aforementioned active control edge trimming device, through the cooperation of an upper blade holder mechanism and a lower blade shaft mechanism, is applied in a soft rewinding machine for electronic aluminum foil equipped with a winding tension weighing roller and a winding machine. On one hand, it achieves edge trimming of soft electronic aluminum foil, especially the end face, thereby solving end face defects, particularly edge quality defects, and improving the overall performance quality of the electronic aluminum foil. On the other hand, by cooperating with the upper blade holder mechanism on the outer surface of the lower blade shaft mechanism for cutting, it minimizes the problems of edge curling and scratches that may occur during trimming, further improving the overall performance quality of the electronic aluminum foil. Furthermore, by cooperating with the winding tension weighing roller and the winding machine, it improves the accuracy and effectiveness of edge trimming, avoiding miscuts and new defects caused by edge trimming. Finally, it can be used in conjunction with other structures to flatten the edge curling of the aluminum foil, achieving a straight end face effect, further avoiding the problems of edge curling and scratches that may occur during soft rewinding of aluminum foil. The following is a detailed explanation... Figures 1 to 7 The active control edge cutting device and the electronic aluminum foil soft rewinding machine are described in detail.

[0046] Electronic aluminum foil soft rewinding machines, also known as aluminum foil rewinding machines for electrolytic capacitors, typically include a main drive mechanism, an unwinding mechanism, a winding mechanism, and an electrical control system. These machines are used for soft rewinding of aluminum foil ranging from 0.06mm to 0.15mm in thickness. However, as mentioned earlier, traditional electronic aluminum foil soft rewinding methods suffer from industry-wide technical challenges such as end-face defects and edge curling. In some embodiments, an electronic aluminum foil soft rewinding machine 100... Figure 1As shown, it includes an active-controlled edge-cutting device 200, a winding tension weighing roller 300, and a winding machine 400; wherein, the active-controlled edge-cutting device 200 is the active-controlled edge-cutting device 200 described in any embodiment; the active-controlled edge-cutting device 200 is disposed between the winding tension weighing roller 300 and the winding machine 400. It is understood that, due to the adoption of the active-controlled edge-cutting device 200 described in any embodiment, the electronic aluminum foil soft rewinding machine 100 also possesses the beneficial technical effects of the active-controlled edge-cutting device 200, which will not be elaborated upon here. As an example, the winding tension weighing roller 300 has a built-in weighing sensor, or as... Figure 2 As shown, the winding tension weighing roller 300 is equipped with a sensor mounting roller 310. The winding tension weighing roller 300 senses the real-time tension during the aluminum foil winding process through its own weighing sensor or through a weighing sensor mounted on the sensor mounting roller 310, and converts the physical tension signal into an electrical signal to feed back to the control system in order to ensure the winding quality as much as possible.

[0047] In some of these embodiments, such as Figure 1 As shown, the electronic aluminum foil flexible rewinding machine 100 also includes a guide roller 600 and a frame 700; the active control edge trimming device 200, the winding tension weighing roller 300, the winding machine 400, and the guide roller 600 are all mounted on the frame 700. The guide roller 600 guides the direction of the aluminum foil 900 rewound by the electronic aluminum foil flexible rewinding machine 100 and ensures a certain tension, while the frame 700 provides an overall structure for easy control. As an example, the guide roller 600 is positioned between the winding tension weighing roller 300 and the winding machine 400, or the winding tension weighing roller 300 is positioned between the guide roller 600 and the winding machine 400. As an example, the number of guide rollers 600 can be multiple, such as... Figure 5 In the illustrated embodiment, the number of guide rollers 600 is two. It is understood that the electronic aluminum foil soft rewinding machine 100 may also include conventional structures such as an uncoiler 800, which are omitted here.

[0048] Combination Figure 1 and Figure 2In some embodiments, the active control edge-cutting device 200 is applied in an electronic aluminum foil soft rewinding machine 100 having a winding tension weighing roller 300 and a winding machine 400. The active control edge-cutting device 200 includes an upper blade holder mechanism 210 and a lower blade shaft mechanism 220. The upper blade holder mechanism 210 and the lower blade shaft mechanism 220 are both disposed between the winding tension weighing roller 300 and the winding machine 400, and the upper blade holder mechanism 210 and the lower blade shaft mechanism 220 are disposed opposite to each other to cooperate in cutting the aluminum foil 900 rewound by the electronic aluminum foil soft rewinding machine 100. The upper blade holder mechanism 210 is configured above the lower blade shaft mechanism 220 to actively cooperate in cutting in an adjustable manner. The lower blade shaft mechanism 220 is configured to clamp the aluminum foil 900 together with the upper blade holder mechanism 210 and cooperate in cutting on the outer surface of the lower blade shaft mechanism 220.

[0049] This design, through the cooperation of the upper blade holder mechanism 210 and the lower blade shaft mechanism 220, is applied to the electronic aluminum foil soft rewinding machine 100, which has a winding tension weighing roller 300 and a winding machine 400. On the one hand, it enables edge trimming of the soft electronic aluminum foil, especially the end face trimming, thereby solving the problem of end face defects, especially edge quality defects, and thus improving the overall performance and quality of the electronic aluminum foil. On the other hand, by cooperating with the upper blade holder mechanism 220 on the outer surface of the lower blade shaft mechanism 220... The 210 structure performs the cutting, minimizing the possibility of edge curling and scratches, thus improving the overall performance and quality of the electronic aluminum foil. Furthermore, its coordination with the winding tension weighing roller 300 and the winding machine 400 enhances the accuracy and effectiveness of the cutting, preventing miscuts and new defects caused by the cutting process. Additionally, it can work with other structures to flatten the curled edges of the aluminum foil, achieving a straight end face and further preventing edge curling and scratches that may occur during soft rewinding and cutting of the aluminum foil.

[0050] To achieve controlled edge trimming and flattening of the soft rewinding of electronic aluminum foil for electrolytic capacitors, in various embodiments, the upper blade holder mechanism 210 is configured above the lower blade shaft mechanism 220 for active cutting in an adjustable manner. That is, the cutting position of the upper blade holder mechanism 210 is adjustable and can be actively adjusted to cooperate with the lower blade shaft mechanism 220 in cutting the aluminum foil 900, ensuring that the edge position of the aluminum foil 900 to be cut is within an adjustable range. This design effectively solves the quality defects of end-face oxidation and misalignment of electronic aluminum foil, as well as the problems of edge curling and scratches during the cutting process, achieving high-quality control of the soft rewinding and cutting of electronic aluminum foil and improving the quality performance of the electronic aluminum foil.

[0051] Combination Figure 2 and Figure 3In some embodiments, the upper tool holder mechanism 210 includes a circular cutter 211, a drive motor 212, and a sliding guide rail 213. The drive motor 212 drives the circular cutter 211 to slide on the sliding guide rail 213 to adjust the relative position of the circular cutter 211 and the lower tool shaft mechanism 220. Figure 2 or Figure 4 In the illustrated embodiment, the number of the circular cutters 211 is a pair. For the embodiment with a bottom cutter 221 described below, as an example, the drive motor 212 drives the circular cutters 211 to slide on the sliding guide rail 213 to adjust the relative positions of the circular cutters 211 and the bottom cutter 221.

[0052] This design, on the one hand, drives the circular blade 211 to slide precisely on the sliding guide rail 213 via the drive motor 212, enabling flexible adjustment of the relative position of the circular blade 211 and the lower blade shaft mechanism 220 or the bottom blade 221. This adapts to the edge-cutting requirements of different specifications of electronic aluminum foil 900, effectively improving edge-cutting adaptability and accuracy, and further reducing the risk of miscutting. On the other hand, the configuration of a pair of circular blades 211 can simultaneously cut the edges of both sides of the aluminum foil 900. Combined with the clamping and cutting of the upper and lower blades, it greatly improves the edge-cutting efficiency while ensuring the consistency of edge-cutting quality on both sides, avoiding the problem of end face skew caused by edge cutting on one side. Furthermore, the mechanically driven sliding adjustment method replaces manual adjustment, reducing operational errors, ensuring the positioning accuracy of the circular blade 211 and the mating parts, reducing defects such as warping and scratches caused by positional deviation during the edge-cutting process, and further optimizing the flatness of the end face of the electronic aluminum foil 900.

[0053] To improve cutting efficiency, as an example, the drive motor 212 adjusts the cutting position of the circular blade 211 in a lateral preload manner, so as to adjust the final width of the aluminum foil 900 after cutting by a one-time contact and cutting method. As an example, such as... Figure 4As shown, the drive motor 212 adjusts the cutting position of the circular blade 211 in the moving direction 230, and the reverse direction is also possible; the relative distance between the two circular blades 211 can also be adjusted in opposite directions at the same time. As an example, the lower blade shaft mechanism 220 or the bottom blade 221 of the lower blade shaft mechanism 220 has a relatively wide cutting engagement position, and the circular blade 211 has a relatively narrow cutting edge. When the winding tension weighing roller 300 conveys the aluminum foil 900 to the winding machine 400, the drive motor 212 preloads the cutting requirement position from the side direction of the aluminum foil 900 according to the position to be cut of the aluminum foil 900 in advance. Synchronously with the conveying of the aluminum foil 900, the circular blade 211 is adjusted to the appropriate cutting requirement position as the cutting position. The circular blade 211 is located at the cutting requirement position and together with the lower blade shaft mechanism 220 or its bottom blade 221, it performs the cutting operation on the aluminum foil 900.

[0054] This design, on the one hand, uses a lateral preloading method to adjust the cutting position of the circular blade 211, achieving one-time contact cutting without multiple reciprocating adjustments, significantly shortening the edge-cutting operation time and greatly improving the cutting efficiency of the electronic aluminum foil soft rewinding machine 100. Simultaneously, it precisely locks the final width of the aluminum foil 900 after edge cutting, effectively avoiding dimensional deviations caused by multiple cuts and ensuring the consistency of the aluminum foil 900 width specification. On the other hand, the drive motor 212 can bidirectionally adjust the position of the circular blade 211 along the moving direction 230, and can also simultaneously adjust the relative distance between the two circular blades 211 in the opposite direction, adapting to the edge-cutting requirements of aluminum foil 900 with different width specifications. This provides high flexibility, eliminating the need to replace special blades or adjust the overall equipment structure, reducing equipment debugging costs and time costs. Furthermore, the lower blade shaft mechanism 220 or... The wide cutting position of the bottom blade 221 is precisely matched with the narrow blade of the circular blade 211. During the process of conveying the aluminum foil 900 from the winding tension weighing roller 300 to the winding machine 400, the wide cutting position provides stable support and guidance for the circular blade 211, preventing blade deviation during cutting. The narrow blade concentrates the cutting force, improving the sharpness and neatness of the cut edge and reducing defects such as burrs and tears on the edge of the aluminum foil 900. On the other hand, the drive motor 212 presets the cutting parameters according to the position to be cut of the aluminum foil 900 in advance, and completes the position adjustment and cutting synchronously with the conveying action of the aluminum foil 900, realizing dynamic and precise edge cutting. This avoids the problems of miscutting and missed cutting caused by the asynchronous static adjustment and conveying. At the same time, it continues the advantages of coordinated cooperation with the winding tension weighing roller 300 and the winding machine 400, further reducing the risk of edge warping and scratches.

[0055] In each embodiment, the lower cutter shaft mechanism 220 is configured to clamp the aluminum foil 900 together with the upper cutter holder mechanism 210, and to perform cutting on the outer surface of the lower cutter shaft mechanism 220; that is, the lower cutter shaft mechanism 220 has an outer surface that cooperates with the upper cutter holder mechanism 210 for cutting. Figure 2 and Figure 4 In some embodiments, the lower blade shaft mechanism 220 includes a bottom blade 221, a blade shaft 222, and an AC drive motor 223. The bottom blade 221 is arranged around the blade shaft 222, and the AC drive motor 223 drives the blade shaft 222 to move the bottom blade 221. As an example, the AC drive motor 223 adopts an active AC frequency conversion drive, so that the rotation of the blade shaft 222 is consistent with the rewinding speed of the aluminum foil 900. This design, through technical modification of the electronic aluminum foil soft rewinding machine, adds an active control edge trimming device 200 to the rewinding machine, effectively removing quality defects such as oxidation and misalignment at the edges of the electronic aluminum foil. Furthermore, the edge trimming device blade shaft 222 adopts an active AC frequency conversion drive, ensuring that the blade shaft 222 is consistent with the rewinding speed of the aluminum foil 900, effectively solving the problem of foil surface scratches during edge trimming, and improving the end face quality and overall performance quality of the electronic aluminum foil.

[0056] In an embodiment with the circular blade 211, as an example, the AC drive motor 223 drives the blade shaft 222 to rotate unidirectionally or reciprocally in an AC frequency conversion manner, thereby driving the bottom blade 221 to rotate unidirectionally or reciprocally, so as to cooperate with the rotating circular blade 211 to achieve the cutting operation of the aluminum foil 900, and to make the rewinding speed of the blade shaft 222 and the aluminum foil 900 consistent, so as to solve the problem of scratches on the foil surface of the aluminum foil 900 during the cutting process.

[0057] This design has several advantages. First, the bottom blade 221 is positioned around the cutter shaft 222, working in conjunction with the AC drive motor 223 to drive the cutter shaft 222, forming a stable base for downward cutting. This, combined with the circular blade 211 of the upper blade holder mechanism 210, precisely coordinates to achieve clamping and cutting of the aluminum foil 900, effectively solving edge quality defects on the end face of the electronic aluminum foil and helping to improve the overall performance and quality of the electronic aluminum foil. Second, the AC drive motor 223 adopts an active AC frequency conversion drive, which can precisely control the rotation speed of the cutter shaft 222 to match the rewinding speed of the aluminum foil 900, avoiding stretching or wrinkling of the aluminum foil 900 due to speed mismatch, reducing foil surface scratches during the cutting process from the root, and further ensuring the surface flatness of the aluminum foil 900. Third, the AC drive motor 223 supports unidirectional or reciprocating rotation modes, which can be flexibly switched according to the material and thickness of the aluminum foil 900 to adapt to the cutting requirements under different working conditions. This, combined with the rotating circular blade 211, achieves efficient cutting, improving the adaptability and flexibility of the cutting process.

[0058] To facilitate a stable cutting process for the aluminum foil 900, in some embodiments, the inner diameter of the bottom blade 221 has the same length as the outer diameter of the blade shaft 222. This ensures stable contact between the upper blade holder mechanism 210 or its circular blade 211, the aluminum foil 900, the bottom blade 221, and the blade shaft 222 during cutting, minimizing the risk of edge warping and scratches. In some embodiments, the bottom blades 221 are in pairs. For example, the number and position of the bottom blades 221 correspond to the number and position of the circular blades 211, such that one circular blade 211 corresponds to one bottom blade 221.

[0059] This design ensures that, on the one hand, the inner diameter of the bottom blade 221 is the same as the outer diameter of the cutter shaft 222, allowing for a tight fit between the two. This creates a stable contact system between the circular blade 211 of the upper blade holder mechanism 210, the aluminum foil 900, the bottom blade 221, and the cutter shaft 222 during cutting, thus constructing a robust cutting support structure. This avoids cutting offset caused by gaps in component fit from the perspective of assembly precision, effectively reducing the risk of edge warping and scratches on the aluminum foil 900 during cutting and ensuring the integrity of the foil surface. On the other hand, the number and position of the pair of bottom blades 221 precisely correspond to the circular blades 211, forming a one-to-one pairing cutting mode. This ensures that each circular blade 211 receives support and cooperation from its dedicated bottom blade 221, allowing the aluminum foil 900 to be cut smoothly on both sides. The uniform force applied to the cutting edge results in a more concentrated and stable cutting force, further improving the neatness of the cut edge and resolving quality defects at the edge of the electronic aluminum foil. Furthermore, the stable contact and precise matching design, combined with the overall functionality of the active control cutting device 200, maintains the advantages of collaborative operation with the winding tension weighing roller 300 and the winding machine 400, improving the accuracy and effectiveness of the cutting and preventing miscuts and new defects. Moreover, through structural adaptability optimization, the stability of the cutting process is enhanced, and the warped edges of the aluminum foil 900 are further flattened, achieving a straight end face. This provides structural assurance for improving the overall performance and quality of the electronic aluminum foil, meeting the high-efficiency production requirements of the electronic aluminum foil soft rewinding machine 100.

[0060] The aforementioned embodiments address quality defects such as end-face oxidation and misalignment in electronic aluminum foil after high-temperature heat treatment. They involve technical modifications to traditional rewinding machines, adding an active-controlled edge-cutting device 200 to remove edge defects. The active-controlled edge-cutting device 200 comprises a lower blade shaft mechanism 220 and an upper blade holder mechanism 210. The lower blade shaft mechanism 220 is driven by an AC drive motor 223 (i.e., an AC variable frequency motor), and two bottom blades 221 with the same outer diameter as the blade shaft 222 are mounted on it. The upper blade holder mechanism 210 is equipped with two independent circular blades 211 (i.e., disc blades), each with double-beveled chrome-plated blades. The upper blade holder mechanism 210 has two pneumatic functions: a lateral pre-loading function and a cutting function, to adjust the final width of the aluminum foil after edge cutting, thereby effectively removing edge defects and improving the overall performance and quality of the electronic aluminum foil.

[0061] To ensure the quality of the trimming and to avoid new problems arising during trimming, in some embodiments, such as Figure 4 As shown, the active control edge trimming device 200 also includes a flattening component 500 disposed between the winding tension weighing roller 300 and the winding machine 400. The flattening component 500 is configured to cooperate with the guide roller 600 of the electronic aluminum foil soft rewinding machine 100 to flatten the aluminum foil 900. This addresses the problems of edge curling and scratches on electronic aluminum foil during the edge trimming process. The electronic aluminum foil soft rewinding machine 100 or its active control edge trimming device 200 is equipped with a flattening component 500. For example, an adjustable flattening device is added as a flattening component 500 to the guide roller 600 of the rewinding machine, such as the pre-winding deflector roller, to effectively flatten the curled edges of the aluminum foil, solving the quality problem of curled edges during soft electronic aluminum foil rewinding and ensuring the quality and straightness of the electronic aluminum foil end face as much as possible. The active control edge cutting device 200 uses an active AC frequency conversion drive for its cutter shaft 222, ensuring that the rewinding speed of the cutter shaft 222 is consistent with that of the aluminum foil 900, which helps to solve the problem of foil surface scratches during the edge cutting process.

[0062] Combination Figure 4 and Figure 5In some embodiments, the flattening assembly 500 includes a rotary pressure roller 510, a pressure roller cylinder 520, and a pressure regulating controller 530. The rotary pressure roller 510 works in conjunction with the guide roller 600 of the electronic aluminum foil soft rewinding machine 100 to flatten the aluminum foil 900. The pressure roller cylinder 520 drives and connects to the rotary pressure roller 510, and is used to adjust the distance between the rotary pressure roller 510 and the guide roller 600. The pressure regulating controller 530 is connected to the pressure roller cylinder 520 and is used to control the output of the pressure roller cylinder 520 to change the pressure of the rotary pressure roller 510 and the guide roller 600 on the aluminum foil 900 by adjusting the distance. As an example, the rotary pressure roller 510 is a rubber roller, such as a polyurethane rubber roller, which ensures the flattening effect of the curled edges and avoids damage to the foil surface and the guide roller 600.

[0063] In this design, the flattening component 500 is positioned between the winding tension weighing roller 300 and the winding machine 400, for example, installed on the guide roller 600 of the electronic aluminum foil soft rewinding machine 100, such as the pre-winding deflector roller. During the electronic aluminum foil soft rewinding and edge trimming process, the rubber-made pressure roller 510 in the flattening component 500 is driven by the pressure of the pressure roller cylinders 520 on both sides to act on the surface of the aluminum foil 900 and the guide roller 600. An interaction force is generated between the pressure roller 510 and the guide roller 600, which flattens the edge warping phenomenon of the aluminum foil between the pressure roller 510 and the guide roller 600. The pressure of the pressure roller cylinder 520 can be adjusted according to the warping of the end face of the aluminum foil 900. The pressure roller 510 is controlled to move up and down by the pressure roller cylinder 520. As an example, the movement direction and positioning accuracy of the pressure roller 510 can be limited by linear bearings and guide columns. An electric button can be used to control the pneumatic reversing valve to control the running direction of the pressure roller cylinder 520, a throttle valve can control the running speed and synchronization of the edge-pressing device, and a pressure reducing valve can control the pressure of the edge-pressing device. This allows the longitudinal edge of the aluminum foil 900 to be flattened by the interaction force of the pressure roller 510 and the guide roller 600, ultimately ensuring a straight aluminum foil end face and effectively solving the problem of edge curling during rewinding of soft electronic aluminum foil. In other embodiments, the effect is better when combined with the surface pressure roller 560.

[0064] Combination Figure 5 and Figure 6In some embodiments, the flattening assembly 500 further includes a lever 540, through which the pressure roller cylinder 520 is driven and connected to the pressure roller 510, to achieve more sensitive pressure adjustment through more sensitive position adjustment, or to achieve lower energy consumption output. To facilitate both manual adjustment and automatic control, in some embodiments, the flattening assembly 500 further includes a digital indicator 550, which is connected to the pressure regulating controller 530 to display the current pressure. In some embodiments, the flattening assembly 500 also includes a lever 540 and a digital indicator 550, with the pressure roller cylinder 520 driven and connected to the pressure roller 510 through the lever 540, and the digital indicator 550 connected to the pressure regulating controller 530 to display the current pressure.

[0065] This design serves two purposes. First, the flattening assembly 500 connects the pressure roller cylinder 520 and the rotary pressure roller 510 via lever 540. Utilizing the lever principle, it amplifies the driving force while improving position adjustment sensitivity, thereby achieving more precise pressure control. This allows the rotary pressure roller 510 to dynamically adapt the pressure according to the degree of edge warping on the aluminum foil 900, flattening the warped edges more efficiently and further ensuring the straightness of the aluminum foil 900's end face, avoiding residual warping defects after trimming. Simultaneously, the lever transmission structure reduces the driving load on the pressure roller cylinder 520, achieving lower energy consumption and meeting the equipment's energy-saving operation requirements. Second, the collaboration between the digital indicator 550 and the pressure controller 530 visually presents the current pressure parameters. This allows operators to monitor the flattening pressure status in real time and quickly perform manual fine-tuning and calibration. It also provides precise pressure feedback to the automatic control system, achieving automated closed-loop pressure control, improving the controllability and stability of the flattening process, and preventing damage or incomplete flattening of the aluminum foil 900 due to improper pressure. Furthermore, the combination of lever 540 and digital indicator 550 provides dual protection for sensitive control and visual monitoring, making the coordination between flattening component 500 and active control edge trimming device 200 more efficient. Combined with the tension control of winding tension weighing roller 300 and winding machine 400, this further improves the linkage accuracy between edge trimming and flattening, reducing new defects caused by flattening lag or pressure deviation. On another front, this structural design balances ease of manual operation with the needs of automated control, adapting to the diverse production scenarios of electronic aluminum foil soft rewinding machine 100. While strengthening the quality control of aluminum foil 900 end face, it improves the overall operating efficiency and ease of operation of the equipment, providing strong support for the stable improvement of the overall performance and quality of electronic aluminum foil.

[0066] To further improve the flattening effect and ensure the best possible edge trimming, avoiding poor edge trimming, combined with Figure 5 and Figure 6As an example, the flattening assembly 500 further includes a face pressure roller 560, a face pressure cylinder 570, and a linear sensor 580. The face pressure cylinder 570 is connected to the face pressure roller 560 and is used to adjust the distance between the face pressure roller 560 and the guide roller 600. The linear sensor 580 is connected to the face pressure roller 560 and is used to sense the displacement of the face pressure roller 560, so as to control the pressure of the face pressure roller 560 on the aluminum foil 900 through the face pressure cylinder 570. As an example, such as Figure 5 As shown, there are two guide rollers 600. In other embodiments, the number of guide rollers 600 may be greater. The pressure roller 510 cooperates with one of the guide rollers 600 to flatten the aluminum foil 900 at one position under the action of the pressure roller cylinder 520; the face pressure roller 560 cooperates with another guide roller 600 to flatten the aluminum foil 900 at another position under the action of the face pressure cylinder 570, so as to obtain a better flattening effect on the aluminum foil 900.

[0067] This design, on the one hand, adds a face pressure roller 560 and a face pressure cylinder 570 to the flattening component 500, forming a dual-position flattening layout with the original rotary pressure roller 510. The rotary pressure roller 510 works with a guide roller 600 to complete one precise flattening, while the face pressure roller 560 works with another guide roller 600 to achieve deep flattening at another position. The dual flattening action is progressive, greatly improving the flatness of the edge and surface of the aluminum foil 900, eliminating the risk of edge warping from the source, laying a solid foundation for the precise edge cutting of the active control edge cutting device 200, and effectively avoiding edge defects caused by uneven foil surface. On the other hand, the linear sensor 580 senses the displacement data of the face pressure roller 560 in real time, providing precise feedback to the face pressure cylinder 570. This makes the pressure control of the face pressure roller 560 on the aluminum foil 900 more targeted, dynamically adapting the pressure according to the thickness, hardness, and other characteristics of the aluminum foil 900. This avoids both insufficient pressure leading to incomplete flattening and excessive pressure causing damage to the foil surface, further ensuring the integrity of the aluminum foil 900 surface. Furthermore, two or more guide rollers 600 are provided, offering stable support for the aluminum foil 900 conveying and forming a multi-point collaborative flattening system with the pressure roller 510 and the face pressure roller 560. This ensures that the aluminum foil 900 remains flat during conveying. Combined with the tension control of the winding tension weighing roller 300, this ensures that the aluminum foil 900 is subjected to uniform force during edge cutting, improving the accuracy and neatness of the edge cutting and reducing defects such as burrs and tears. On the other hand, the multi-component collaborative flattening structure forms an efficient linkage with the active control edge cutting device 200 and the winding machine 400. Through the design of dual flattening combined with precise sensor control, it not only strengthens the correlation between flattening effect and edge cutting quality, but also further expands the equipment's adaptability to different specifications of aluminum foil 900. At the same time, it continues the advantages of preventing defects such as curling and scratches, helping the electronic aluminum foil soft rewinding machine 100 to stably output high-quality electronic aluminum foil 900, providing a more reliable substrate for subsequent processing stages.

[0068] As an example, the flattening assembly 500 further includes a self-aligning bearing, a bearing housing, a bearing housing beam, a guide column, a linear bearing, a linear bearing housing, and a crossbeam frame. The self-aligning bearing is disposed on the bearing housing, and the bearing housing is disposed on the bearing housing beam. The guide column guides the movement direction of the rotary pressure roller 510, causing the pressure roller cylinder 520 to drive the rotary pressure roller 510 to move along the direction defined by the guide column. The linear bearing is disposed on the linear bearing housing, and the linear bearing housing is disposed on the crossbeam frame. For example, multiple linear bearings can be used for positioning to achieve the reliability and stability of the flattening operation of the flattening assembly 500. In an embodiment with a frame 700, the bearing housing beam and the crossbeam frame are respectively disposed on the frame 700. As an example, the flattening assembly 500 is controlled by an electromagnetic pneumatic reversing valve via an electric button. The electromagnetic pneumatic reversing valve controls the running direction of the pressure roller cylinder 520. The pressure roller cylinder 520 drives the connecting rubber roller bearing seat beam. The pressure roller bearing and the pressure roller 510 are installed on the rubber roller bearing seat. The pressure roller 510 is arranged parallel to the guide roller 600 on the upper part of the guide roller 600. The pressure roller 510 moves up and down along the guide column on the guide roller 600. In a specific application embodiment, the flattening assembly 500 uses a continuous and stable compressed air source, and uses a 24V power supply to control the electromagnetic pneumatic reversing valve to switch the air source outlet. The two air outlets of the electromagnetic pneumatic valve are connected to two cylinders via compressed air pipelines to control the up and down movement of the pressure roller 510 and the rubber roller bearing seat. The direction of the pressure roller 510 is controlled by linear bearings and guide columns. As an example, the pressure roller cylinder 520 uses a continuous and stable compressed air source with a pressure greater than 0.4MPa. A 24V power supply controls the switching of the electromagnetic pneumatic reversing valve, and a linear bearing controls the movement direction of the pressure roller 510.

[0069] This design serves several purposes. First, it provides stable guidance and positioning support for the pressure roller 510, ensuring its smooth movement along a defined direction and preventing deviation or skewing during flattening. This significantly improves the reliability of the flattening assembly 500 and, in conjunction with the guide roller 600, ensures uniform pressure on the aluminum foil 900, further guaranteeing end-face flatness. Second, it strengthens the overall structural rigidity of the flattening assembly 500, resisting vibration interference during rewinding and preventing flattening failure due to component loosening. This provides a stable pre-conditioning guarantee for the precise edge cutting of the actively controlled edge cutting device 200. Third, it facilitates rapid response and smooth drive of the pressure roller cylinder 520. Combined with electrical button control, this simplifies the operation process and ensures precise and controllable movement of the pressure roller 510, reducing human intervention errors.

[0070] As an example, such as Figure 5 and Figure 7As shown, the electronic aluminum foil flexible rewinding machine 100 or the winding machine 400 is equipped with a winding shaft 410, an inflation device 420, a drive device 430, a motor 440, a pulley 450, a bracket 460, a cylinder 470, a locking pin 480, and a brake 490. The winding shaft 410 is rotatably mounted on the frame 700. The locking pin 480 is used to lock or release the winding shaft 410 so that the winding shaft 410 is in a rotatable or non-rotatable state. The inflation device 420, the bracket 460, and the cylinder 470 are respectively mounted on the frame 700. The inflation device 420 is connected to the cylinder 490. A cylinder 470 is connected to the take-up shaft 410 and is used to adjust the contact pressure, i.e., tension, of the aluminum foil 900 by the take-up shaft 410. A motor 440 and a pulley 450 are mounted on the bracket 460. A drive device 430 is mounted on the motor 440 and is used to drive the motor 440 to work. The motor 440 drives the take-up shaft 410 through the pulley 450 to drive the pulley 450 to rotate, thereby driving the take-up shaft 410 to rotate. A brake 490 is connected to the pulley 450 to stop the pulley 450 from rotating in a controlled state.

[0071] This design allows for several advantages. First, the locking pin 480 can flexibly lock or release the winding shaft 410. Combined with the inflation device 420 and cylinder 470, this precisely adjusts the contact pressure (tension) between the winding shaft 410 and the aluminum foil 900, ensuring stable tension during rewinding and preventing edge deviation due to tension fluctuations, thus improving edge cutting accuracy. Second, the motor 440 drives the winding shaft 410 via pulley 450, and the brake 490 enables precise start-stop control. This, along with the active control edge cutting device 200 and the winding tension weighing roller 300, ensures synchronized edge cutting and winding rhythm, reducing the risk of scratches and wrinkles on the aluminum foil 900. Third, the stable assembly of all components with the frame 700 enhances the stability of the electronic aluminum foil soft rewinding machine 100's winding system, further ensuring the flatness of the aluminum foil 900's end face and contributing to improved overall performance and quality of the electronic aluminum foil.

[0072] Example 1: On a certain day of a certain month of a certain year, a rewinding machine produced soft electronic aluminum foil with serial number 85067213. The production process was 0.108mm thick and 250m / min. The active control edge cutting device 200 and its flattening component 500 were used. After production, the quality of the aluminum coil end face was normal, and the electronic aluminum foil had no quality defects such as oxidation, misalignment, curling, or scratches.

[0073] Example 2: On a certain day of a certain month of a certain year, a rewinding machine produced soft electronic aluminum foil with serial number 85076533. The production process was 0.138mm thick and 300m / min. The active control edge cutting device 200 and its flattening component 500 were used. After the production was completed, the quality of the aluminum coil end face was normal, and the electronic aluminum foil had no quality defects such as oxidation, misalignment, curling, or scratches.

[0074] Comparative Example 1: On a certain day of a certain month of a certain year, a rewinding machine produced soft electronic aluminum foil with serial number 84035112. The production process was 0.134mm thick and 100m / min. The active control edge cutting device 200 was not used. After the aluminum coil was produced, the end face of the electronic aluminum foil coil had oxidation and mis-layering problems, resulting in substandard waste.

[0075] Comparative Example 2: On a certain day of a certain month of a certain year, a rewinding machine produced soft electronic aluminum foil with serial number 84061711. The production process was 0.132mm thick and 100m / min. The active control edge cutting device 200 without the flattening component 500 was used. After the aluminum coil was produced, some electronic aluminum foil had slight edge curling defects, resulting in substandard waste.

[0076] As can be seen from the comparison, the active control edge cutting device 200 and the electronic aluminum foil soft rewinding machine in the relevant embodiments have avoided the problems of edge curling and scratches that may occur during edge cutting as much as possible, thus improving the overall performance and quality of electronic aluminum foil. The effect is even better when combined with the flattening component 500.
