Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery pole piece, in particular to an electrode piece processing method, device and storage medium. BACKGROUND

[0002] In the modern science and technology industry system, the electrode piece as a core functional component has deeply penetrated into the key fields such as battery manufacturing, medical electronic equipment, sensor, etc., and its quality stability and performance advantage and disadvantage directly determine the running accuracy, energy efficiency level and service reliability of the downstream equipment or system, occupying an irreplaceable position in the industry chain.

[0003] In the industrialized processing flow of the electrode piece, the conveying and pretreatment of the metal sheet are the core link of connecting the raw material and the semi-finished product, and the process precision of this link directly affects the implementation effect of the subsequent winding, pressing and other processes. However, in the current industry, the traditional processing technology generally adopted in the metal sheet conveying link is difficult to realize accurate and stable control of the metal sheet tension. Specifically, the metal sheet tension fluctuation range is large and the stability is poor under the traditional conveying mode, which not only easily leads to appearance defects such as wrinkles and deformation of the metal sheet in the transmission process, but also causes the problem of significant deviation of the overlapping degree between the multiple metal sheet layers in the subsequent winding process, thereby causing a chain negative impact on the core performance and product quality of the electrode piece.

[0004] From the actual application scene, such quality defects will directly cause the imbalance of the internal resistance distribution of the battery, cause the attenuation of the charging and discharging efficiency, and greatly shorten the cycle life of the battery, ultimately increase the operation and maintenance cost and the core component replacement frequency of the terminal equipment. As can be seen, the unstable transmission mode of the metal sheet tension has become a key factor restricting the quality stability and performance consistency of the electrode piece finished product, which is difficult to meet the strict technical requirements of high-end electronic equipment on core components. SUMMARY

[0005] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides an electrode piece processing method, device and storage medium, which can improve the quality of electrode piece production.

[0006] In a first aspect, the present application provides an electrode piece processing method applied to an electrode piece processing device, the electrode piece processing device comprising, in sequence along the conveying direction of the metal sheet, a feeding mechanism, a tensioning mechanism, a winding mechanism, a taking mechanism and a flattening mechanism, the tensioning mechanism comprising a fixed part and a movable part, the outer side of the fixed part and the movable part being wound with a metal sheet, and the winding mechanism comprising a first clamping structure and a cutting structure; The electrode piece processing method comprises: driving the movable part to move away from the fixed part to make the metal sheet discharged by the feeding mechanism be received in the tensioning mechanism; stopping the feeding of the metal sheet from the feeding mechanism to the tensioning mechanism, and driving the movable part to move close to the fixed part to make the metal sheet received in the tensioning mechanism be released to the winding mechanism; in the process of moving the movable part to the fixed part, controlling the first clamping structure to extend and clamp the metal sheet sent by the tensioning mechanism, and driving the first clamping structure to rotate to wind the metal sheet to form a first semi-finished product; wherein the rotation speed of the first clamping structure is determined according to the moving speed of the movable part to the fixed part; cutting the metal sheet connected with the first semi-finished product by the cutting structure; moving the separated first semi-finished product to the flattening mechanism by the taking mechanism; welding the multiple layers of the metal sheet in the first semi-finished product into one by the flattening mechanism to obtain an electrode sheet.

[0007] According to the electrode sheet processing method of the first aspect of the present application, at least the following beneficial effects are achieved: first, the processing process is started, and the feeding mechanism is controlled to deliver the metal sheet to the tensioning mechanism, while the movable part of the tensioning mechanism is controlled to move away from the fixed part. In this process, the metal sheet is discharged from the feeding mechanism and gradually stored outside the fixed part and the movable part. The storage amount of the metal sheet in the tensioning mechanism can be adjusted as needed. Then, the feeding mechanism is controlled to stop delivering the metal sheet, and the movable part of the tensioning mechanism is controlled to move towards the fixed part. The metal sheet previously stored in the tensioning mechanism will be discharged and delivered to the winding mechanism. When the metal sheet reaches the winding mechanism, the first clamping structure is controlled to extend to clamp the metal sheet delivered from the tensioning mechanism. Then, the first clamping structure is driven to rotate, and the metal sheet starts to wind under the rotation of the clamping structure, gradually forming the first semi-finished product. After the first semi-finished product is formed, the cutting mechanism is controlled to cut the remaining metal sheet connected to the first semi-finished product. After cutting, the taking mechanism is controlled to move the separated first semi-finished product to the flattening mechanism. Finally, in the flattening mechanism, the multiple layers of metal sheets in the first semi-finished product are pressure-welded together under suitable pressure and temperature conditions, ensuring that the multiple layers of metal sheets are firmly bonded and forming a high-quality electrode sheet. The design of the fixed part and the movable part of the tensioning mechanism allows the tension of the metal sheet to be adjusted during storage and discharge. During the feeding process, as the metal sheet is continuously discharged from the feeding mechanism, the movable part moves away from the fixed part to accommodate more metal sheets. At the same time, the tension of the metal sheet can be adjusted by changing the position of the movable part. This tight state is within a controllable range. When the metal sheet is tight, it can resist external interference factors and maintain good surface flatness. The tight metal sheet can be evenly distributed during winding, and each layer can be accurately attached to the previous layer, ensuring the uniformity of the electrode sheet on the winding structure and improving the overall quality of the electrode sheet.

[0024] In the modern technology industry system, electrode sheets, as core functional components, have deeply penetrated into key fields such as battery manufacturing, medical electronic equipment, and sensors. Their quality stability and performance directly determine the operating accuracy, energy efficiency, and service reliability of downstream equipment or systems, occupying an irreplaceable position in the industry chain.

[0025] In the industrial processing of electrode sheets, the conveying and pretreatment of metal sheets is a crucial link between raw materials and semi-finished products. The precision of this process directly affects the effectiveness of subsequent winding, pressing, and other processes. However, the traditional processing technology commonly used in the industry currently struggles to achieve precise and stable control of metal sheet tension during the conveying stage. Specifically, the traditional conveying method results in large fluctuations and poor stability in metal sheet tension. This not only easily leads to appearance defects such as wrinkles and deformation during transport but also causes significant deviations in the overlap between multiple layers of metal sheets in the subsequent winding process, thus creating a chain reaction of negative impacts on the core performance and product quality of the electrode sheets.

[0026] From a practical application perspective, such quality defects directly lead to an imbalance in the internal resistance distribution of the battery, causing a decrease in charging and discharging efficiency, significantly shortening the battery's cycle life, and ultimately increasing the maintenance costs of terminal equipment and the frequency of core component replacement. Therefore, the unstable transmission mode of metal sheet tension has become a key factor restricting the quality stability and performance consistency of finished electrode sheets, making it difficult to meet the stringent technical requirements of high-end electronic devices for core components.

[0027] Based on this, this application provides an electrode sheet processing method, equipment, and storage medium to solve the aforementioned technical problems. The technical solutions provided by this application will be described in detail below.

[0028] Firstly, referring to Figure 1 , Figure 9 and Figure 10 This application provides an electrode sheet processing method, which is applied to an electrode sheet processing equipment. The electrode sheet processing equipment includes, in sequence along the conveying direction of the metal sheet, a feeding mechanism, a tensioning mechanism, a winding mechanism, a picking mechanism 400, and a flattening mechanism. The tensioning mechanism includes a fixed part and a movable part. The fixed part and the movable part are wrapped with metal sheets. The winding mechanism includes a first clamping structure 310 and a cutting structure 320.

[0029] The electrode processing method may include, but is not limited to, the following steps: Step S110: While controlling the feeding mechanism to feed the metal sheet to the tensioning mechanism, drive the moving part to move away from the fixed part, so that the metal sheet fed by the feeding mechanism is collected in the tensioning mechanism.

[0030] Step S120: Stop the feeding mechanism from feeding the metal sheet to the tensioning mechanism, and at the same time drive the moving part to move closer to the fixed part, so that the metal sheet stored in the tensioning mechanism is released to the winding mechanism.

[0031] Step S130: During the movement of the movable part toward the fixed part, the first clamping structure is extended and clamped to the metal sheet fed by the tensioning mechanism, and the first clamping structure is driven to rotate to wind the metal sheet to form the first semi-finished product; wherein, the rotation speed of the first clamping structure is determined according to the displacement speed of the movable part toward the fixed part.

[0032] Step S140: Cut the metal sheet connected to the first semi-finished product by the cutting structure.

[0033] Step S150: The material handling mechanism transfers the separated first semi-finished product to the flattening mechanism.

[0034] Step S160: Use a flattening mechanism to press-weld the multi-layer metal sheets in the first semi-finished product into one piece to obtain an electrode sheet.

[0035] In steps S110 to S160, the processing is first initiated by controlling the feeding mechanism to feed metal sheets to the tensioning mechanism. Simultaneously, the movable part of the tensioning mechanism is moved away from the fixed part. During this process, the metal sheets are released from the feeding mechanism and gradually stored outside the fixed and movable parts. The amount of metal sheets stored in the tensioning mechanism can be adjusted as needed. Next, the feeding mechanism stops feeding the metal sheets, and the movable part of the tensioning mechanism moves towards the fixed part, releasing the previously stored metal sheets and feeding them towards the winding mechanism. When the metal sheets reach the winding mechanism, the first clamping structure extends to clamp the metal sheets from the tensioning mechanism. Then, the first clamping structure is driven to rotate, and the metal sheets begin to wind under the rotation of the clamping structure, gradually forming the first semi-finished product. After the first semi-finished product is formed, the cutting mechanism cuts off the remaining metal sheets connected to the first semi-finished product. After cutting, the material handling mechanism transfers the separated first semi-finished product to the flattening mechanism. Finally, in the flattening mechanism, by applying appropriate pressure and temperature, the multiple layers of metal sheets in the first semi-finished product are welded together, ensuring a firm bond between the layers and forming a high-quality electrode sheet. The design of the fixed and movable parts of the tensioning mechanism allows for tension adjustment during the loading and unloading of the metal sheets. During unloading, as the metal sheets are continuously released from the unloading mechanism, the movable part moves away from the fixed part to accommodate more metal sheets. Simultaneously, the tension of the metal sheets can be adjusted by changing the position of the movable part, and this tension is within a controllable range. When the metal sheets are taut, they can resist interference from external forces, maintaining better surface flatness. The taut metal sheets are more evenly distributed during winding, with each layer accurately adhering to the previous one, thus ensuring the uniformity of the electrode sheet in the winding structure and improving the overall quality of the electrode sheet.

[0036] Reference Figure 2 and Figures 9 to 11 It can be understood that the feeding mechanism includes a feeding roller 110; the fixed part includes a fixed plate 211 and n+1 fixed rollers 212, the fixed rollers 212 being distributed vertically at intervals on the fixed plate 211; the movable part includes a movable plate 221 and n movable rollers 222, the movable rollers 222 being distributed vertically at intervals on the movable plate 221; the uppermost fixed roller 212 of the fixed plate 211 is the feeding end of the tensioning mechanism, and the lowermost fixed roller 212 of the fixed plate 211 is the discharging end of the tensioning mechanism; the metal sheet is alternately wound around the outside of all the fixed rollers 212 and movable rollers 222 from top to bottom; the winding mechanism also includes a second clamping structure 330, the second clamping structure 330 being located in front of the first clamping structure 310 along the metal sheet conveying direction. Specifically, step S110 may include, but is not limited to, the following steps: Step S210: Control the second clamping structure to clamp the metal sheet.

[0037] Step S210: Drive the feeding roller to rotate at a preset first speed and feed out the metal sheet.

[0038] Step S230: Synchronously control the movable plate to move away from the fixed plate at a preset second speed, so that the metal sheet is stored in the tensioning mechanism; wherein, the first speed is 2n times the second speed.

[0039] In steps S210 to S230, the second clamping structure is controlled to clamp the metal sheet, preventing the metal strip from springing back at the discharge end when it is conveyed to the tensioning mechanism. Next, the unloading roller is activated to rotate and release the metal sheet at a preset first speed. Simultaneously, the movable plate is controlled to move away from the fixed plate at a preset second speed, with the metal sheet sequentially and crosswise wound around the outside of all the fixed and movable rollers from top to bottom. Since the first speed is 2n times the second speed, this speed relationship ensures that the metal sheet can be orderly stored in the tensioning mechanism, achieving precise control of the tension of the metal sheet within the tensioning mechanism. As the movable plate moves, the metal sheet gradually accumulates between the fixed and movable rollers. During this process, it is ensured that the metal sheet is not too tight or too loose during storage, effectively avoiding wrinkles or other quality problems caused by improper tension, providing a good foundation for subsequent winding operations.

[0040] In one embodiment, the fixed part includes 4 fixed rollers and the movable part includes 3 movable rollers. When the movable plate moves toward the fixed plate at a speed of v, the speed at which the feeding roller rotates to feed the metal sheet is 6v.

[0041] Reference Figure 3 , Figure 9 and Figure 12 It is understood that the winding mechanism also includes a third clamping structure 340, which is located behind the first clamping structure 310 along the metal sheet transport direction, and the first clamping structure 310 is positioned between the second clamping structure 330 and the third clamping structure 340. Step S120 may include, but is not limited to, the following steps: Step S310: Stop the feeding mechanism from feeding metal sheets to the tensioning mechanism.

[0042] Step S320: Control the movable plate to move a preset first distance toward the fixed plate.

[0043] Step S330: Control the second clamping structure to pull the clamped metal sheet towards the third clamping structure by a preset second distance, and the third clamping structure clamps the metal sheet transferred by the second clamping structure; wherein, the second distance is 2n times the first distance.

[0044] In steps S310 to S330, the feeding mechanism is controlled to stop feeding metal sheets to the tensioning mechanism, ensuring that no new metal sheets enter the tensioning mechanism. This prepares for the subsequent release of metal sheets from the tensioning mechanism, bringing the entire system into a relatively stable state and avoiding interference from new materials. Next, the movable plate is controlled to move a preset first distance toward the fixed plate. Due to the movement of the movable plate, the metal sheets previously stored in the tensioning mechanism begin to be released, and the winding state of the metal sheets between the fixed roller and the movable roller begins to change, gradually moving toward the winding mechanism. At the same time, the second clamping structure is controlled to pull the clamped metal sheets toward the third clamping structure a preset second distance. Simultaneously, the third clamping structure is controlled to clamp the metal sheets transferred from the second clamping structure. Since the second distance is 2n times the first distance, tension control and accurate transfer of the metal sheets during the release process are ensured, avoiding problems such as wrinkles and twists caused by improper feeding, which helps to improve the processing quality of the electrode sheets.

[0045] In one embodiment, the fixed part includes 4 fixed rollers and the movable part includes 3 movable rollers. When the movable plate is displaced 1cm toward the fixed plate, the second clamping structure pulls the clamped metal sheet 6cm toward the third clamping structure.

[0046] Reference Figure 4 , Figure 9 and Figure 12 It is understood that step S130 may include, but is not limited to, the following steps: Step S410: Control the second clamping structure to open and retract to the initial position.

[0047] Step S420: Drive the first clamping structure to extend and clamp the metal sheet located between the second clamping structure and the third clamping structure.

[0048] Step S430: Control the movable plate to move towards the fixed plate at a preset third speed.

[0049] Step S440: Calculate the first rotational speed based on the third speed and the width of the clamping part in the first clamping structure.

[0050] Step S450: Control the rotation of the first clamping structure according to the first rotation speed.

[0051] Step S460: When the displacement distance of the movable plate reaches the preset threshold, stop the displacement of the movable plate and allow the metal sheet to be wound on the first clamping structure to form the first semi-finished product.

[0052] In steps S410 to S460, firstly, the second clamping structure is opened and returned to its initial position, releasing the metal sheet from the second clamping structure and creating conditions for the subsequent operation of the first clamping structure and the smooth winding of the metal sheet, avoiding interference caused by the presence of the second clamping structure during the winding process. Next, the first clamping structure extends and clamps the metal sheet located between the second and third clamping structures. The movable plate is then controlled to move towards the fixed plate at a preset third speed, and simultaneously, the first clamping structure is controlled to rotate according to a determined first rotation speed. During rotation, the metal sheet is continuously wound onto the first clamping structure by the tensioning mechanism in conjunction with the movement of the movable plate, gradually forming a first semi-finished product. The first rotation speed is determined by the third speed and the width of the clamping portion of the first clamping structure to ensure that the metal sheet is wound evenly and tightly onto the first clamping structure during the winding process. Determining the rotation speed based on the moving speed of the movable plate and the width of the clamping portion of the first clamping structure achieves precise control of the metal sheet winding process. This precise control ensures uniform tension of the metal sheets during winding, allowing each layer to adhere tightly and preventing quality issues such as wrinkles and looseness, thereby improving the quality of the first semi-finished product.

[0053] Reference Figure 5 , Figure 10 and Figure 12 It is understood that the winding mechanism also includes a guide structure 350, which is located below the first clamping structure 310. Following step S140, the following steps are included, but not limited to: Step S510: When the moving plate moves a distance that reaches a preset distance threshold, control the moving plate to stop moving and control the third clamping structure to open.

[0054] Step S520: Drive the guide structure to move towards the first clamping structure, and push the metal strip released by the third clamping structure towards the first clamping structure.

[0055] Step S530: Continue to control the rotation of the first clamping structure until the metal strip released by the third clamping structure is completely wrapped.

[0056] In steps S510 to S530, when the movable plate moves a distance reaching a preset distance threshold, the winding of the first semi-finished product is partially completed. At this point, the movable plate is stopped to prevent further material feeding from interfering with subsequent operations. Simultaneously, the third clamping structure is opened, allowing the remaining metal strip connected to the first semi-finished product to move freely. The guide structure is moved towards the first clamping structure, interacting with the metal strip released from the third clamping structure and pushing it towards the first clamping structure to ensure accurate movement without twisting or deforming. Driven by the guide structure, the metal strip released from the third clamping structure gradually winds around the first semi-finished product under the rotation of the first clamping structure, improving the production quality of the electrode sheet.

[0057] Reference Figure 6 , Figure 10 and Figure 13 It is understood that the material receiving mechanism 400 includes a receiving structure, a pressing cylinder 420, a feeding cylinder 430, and a first material transfer structure 440. The receiving structure includes a lower receiving plate 411, an upper receiving plate 412, and a reset component, with the reset component disposed between the upper receiving plate 412 and the lower receiving plate 411. Step S150 may include, but is not limited to, the following steps: Step S610: Drive the receiving structure to move towards the first clamping structure, so that the first clamping structure is between the upper receiving plate and the lower receiving plate.

[0058] Step S620: Control the first clamping structure to open and retract, so that the first semi-finished product falls from the first clamping structure onto the receiving plate.

[0059] Step S620: Drive the receiving structure to retract to the initial position in a direction away from the first clamping structure.

[0060] Step S630: Control the pressing cylinder to push the upper receiving plate towards the lower receiving plate, so that the lower receiving plate is close to the upper receiving plate and flattens the first semi-finished product to form the second semi-finished product.

[0061] Step S640: Control the retraction of the drive end of the pressing cylinder, so that the upper receiving plate moves away from the lower receiving plate through the reset component.

[0062] Step S650: Control the feeding cylinder to push out the second semi-finished product from the receiving plate and transfer it to the flattening mechanism through the first material transfer structure.

[0063] In steps S610 to S620, the receiving structure is controlled to move towards the first clamping structure, so that the first clamping structure is positioned between the upper receiving plate and the lower receiving plate. Then, the first clamping structure is controlled to open and retract, and the first semi-finished product originally clamped on the first clamping structure falls onto the lower receiving plate under the action of gravity. During the material handling process, the precise movement of the receiving structure and the cooperation of the first clamping structure minimize potential damage to the first semi-finished product.

[0064] In steps S630 to S660, the receiving structure is then moved away from the first clamping structure to its initial position. The pressing cylinder pushes the upper receiving plate towards the lower receiving plate. Under the action of the pressing cylinder, the lower receiving plate moves closer to the upper receiving plate, applying pressure to the first semi-finished product and flattening it, thus forming the second semi-finished product. This improves the surface flatness and the tightness of the metal sheets between different layers. Afterwards, the driving end of the pressing cylinder retracts. Since the reset component is located between the upper and lower receiving plates, when the pressing cylinder retracts, the upper receiving plate moves away from the lower receiving plate via the reset component, returning to its initial relative position. Finally, the feeding cylinder pushes the second semi-finished product off the lower receiving plate, and the first material transfer structure moves the second semi-finished product to the flattening mechanism.

[0065] Reference Figure 7 , Figure 14 It is understood that the flattening mechanism includes a transfer wheel 510, a hot pressing structure 520, an alignment structure 530, and a transfer module. The transfer wheel 510 is circumferentially spaced with a plurality of first fixing positions 511. The alignment structure 530 and the transfer module are disposed between the transfer wheel 510 and the hot pressing structure 520. Step S150 may include, but is not limited to, the following steps: Step S710: Control the material handling mechanism to sequentially transfer the separated first semi-finished products to each first fixed position; wherein each first fixed position can accommodate multiple first semi-finished products.

[0066] Correspondingly, step S160 may include, but is not limited to, the following steps: Step S720: Control the transfer module to remove the first semi-finished product from the first fixed position and transfer it to the alignment structure.

[0067] Step S730: The sides of the first semi-finished product are pressed by the alignment structure to align the metal sheets of different layers in the first semi-finished product.

[0068] Step S740: Control the transfer module to remove the aligned first semi-finished product from the alignment structure and transfer it to the hot pressing structure.

[0069] Step S750: The multi-layer metal sheets in the first semi-finished product are pressed and welded together by a hot pressing structure to form an electrode sheet.

[0070] In steps S710 to S750, the material handling mechanism is controlled to sequentially transfer the separated first semi-finished product to the first fixed position of the transfer wheel of the flattening mechanism, providing a storage location for the first semi-finished product. Subsequently, the transfer module is controlled to remove the first semi-finished product from the first fixed position and transfer it to the alignment structure. The alignment structure is then controlled to press the sides of the first semi-finished product to align the metal sheets of different layers in the first semi-finished product, ensuring the quality of the electrode sheet after pressure welding. The transfer module is again controlled to remove the aligned and flattened first semi-finished product from the alignment structure and transfer it to the hot pressing structure. The hot pressing structure is controlled to press weld the multiple layers of metal sheets in the first semi-finished product together to form the final electrode sheet.

[0071] Reference Figure 8 , Figures 14 to 16 It is understood that the flattening mechanism also includes a preheating disc 540 and a preheating structure 550. The preheating disc is circumferentially spaced with several second fixing positions 541. Two adjacent second fixing positions 541 form a first angle with the center of the preheating disc 540. The preheating structure 550 is located beside the preheating disc 540. The transfer module includes a first transfer structure and a second transfer structure. The first transfer structure is located between the transfer disc 510 and the preheating disc 540, and the second transfer structure is located between the preheating disc 540 and the hot pressing structure 520. Step S720 may include, but is not limited to, the following steps: Step S810: Control the first transfer structure to remove the first semi-finished product from the first fixed position and transfer it to the alignment structure.

[0072] Correspondingly, step S740 may include, but is not limited to, the following steps: Step S820: Control the first transfer structure to remove the aligned first semi-finished product from the alignment structure and transfer it to the second fixed position.

[0073] Step S830: Synchronously control the preheating structure to press the first semi-finished product on the second fixed position at the corresponding location with a preset first temperature and first pressure.

[0074] Step S840: Synchronously control the second transfer structure to take out the preheated and pressed first semi-finished product from the second fixed position at the corresponding location and transfer it to the hot pressing structure.

[0075] Step S850: Whenever the first transfer structure transfers a first semi-finished product to an empty second fixed position, the preheating wheel is controlled to rotate by a first angle.

[0076] The time it takes for the first transfer structure to move the first semi-finished product from the alignment structure to the empty second fixed position is equal to the time it takes for the preheating structure to press the first semi-finished product on the corresponding second fixed position, and equal to the time it takes for the second transfer structure to move the first semi-finished product from the corresponding second fixed position to the hot pressing structure.

[0077] In step S830, the first semi-finished product is pre-treated by a preset temperature and pressure. Preheating makes it easier for the metal sheets to fuse during hot pressing, which can improve the bonding performance between the metal sheets and improve the quality of the final electrode sheet.

[0078] Furthermore, in steps S810 to S850, the combination of rotation control and time control of the preheating turntable 540 ensures a high degree of continuity in the production process. This allows for uninterrupted processing of the first semi-finished product, improving equipment utilization and reducing production costs. Because the preheating turntable is circumferentially spaced with several second fixed positions 541, the first transfer structure, the preheating structure 550, and the second transfer structure can simultaneously act on the first semi-finished product in different second fixed positions 541. This time synchronization of each stage means the equipment is always in operation, maximizing equipment utilization, minimizing idle time, and thus improving overall production efficiency.

[0079] Secondly, this application also provides an electrode sheet processing apparatus, comprising: at least one memory, at least one processor and at least one program, wherein the program is stored in the memory and the processor executes one or more programs to implement the above-described electrode sheet processing method.

[0080] In this processing equipment, the processing is first initiated by controlling the feeding mechanism to feed metal sheets to the tensioning mechanism. Simultaneously, the movable part of the tensioning mechanism moves away from the fixed part. During this process, the metal sheet is released from the feeding mechanism and gradually stored outside the fixed and movable parts; the amount of metal sheet stored in the tensioning mechanism can be adjusted as needed. Next, the feeding mechanism stops feeding the metal sheet, and the movable part of the tensioning mechanism moves towards the fixed part, releasing the previously stored metal sheet and feeding it towards the winding mechanism. When the metal sheet reaches the winding mechanism, the first clamping structure extends and clamps the metal sheet from the tensioning mechanism. Then, the first clamping structure rotates, and the metal sheet begins to wind under the rotation of the clamping structure, gradually forming the first semi-finished product. After the first semi-finished product is formed, the cutting mechanism cuts off the remaining metal sheet connected to it. After cutting, the unloading mechanism transfers the separated first semi-finished product to the flattening mechanism. Finally, in the flattening mechanism, by applying appropriate pressure and temperature, the multiple layers of metal sheets in the first semi-finished product are welded together, ensuring a firm bond between the layers and forming a high-quality electrode sheet. The design of the fixed and movable parts of the tensioning mechanism allows for tension adjustment during the loading and unloading of the metal sheets. During unloading, as the metal sheets are continuously released from the unloading mechanism, the movable part moves away from the fixed part to accommodate more metal sheets. Simultaneously, the tension of the metal sheets can be adjusted by changing the position of the movable part, and this tension is within a controllable range. When the metal sheets are taut, they can resist interference from external forces, maintaining better surface flatness. The taut metal sheets are more evenly distributed during winding, with each layer accurately adhering to the previous one, thus ensuring the uniformity of the electrode sheet in the winding structure and improving the overall quality of the electrode sheet.
