Abstract
Description
Technical Field
[0001] This application relates to the field of battery processing equipment technology, and in particular to a cutting and stacking integrated machine. Background Technology
[0002] Battery cells typically employ a configuration of an upper single-sided cell, a positive double-sided cell, a negative double-sided cell, and a lower single-sided cell. Because single-sided and double-sided cells are different types, related technologies employ separate manufacturing systems for each.
[0003] However, equipping single-sided and double-sided wafers with separate wafer fabrication systems will not only occupy a lot of factory space, but also lead to complex wafer fabrication paths and higher equipment costs. Summary of the Invention
[0004] This application discloses an integrated cutting and stacking machine, which can occupy less factory space, simplify the wafer fabrication path, and reduce equipment costs.
[0005] To achieve the above objectives, a cutting and stacking integrated machine is disclosed, comprising: A first film-making system includes a first polar single-sided film-making device, at least one first polar double-sided film-making device, a first film-transferring mechanism, and a first cutting mechanism. The first film-transferring mechanism is configured corresponding to the first polar single-sided film-making device and the first polar double-sided film-making device, and the first film-transferring mechanism is located downstream of the first polar double-sided film-making device and the first polar single-sided film-making device. The first cutting mechanism is located downstream of the first film-transferring mechanism. A second production system; and, A wafer stacking device is provided corresponding to the first wafer fabrication system and the second wafer fabrication system, and the wafer stacking device is located downstream of the first wafer fabrication system and the second wafer fabrication system.
[0006] Since the first transfer mechanism is set up to correspond to the first polarity single-sided sheet making equipment and the first polarity double-sided sheet making equipment, and the first transfer mechanism is located downstream of the first polarity double-sided sheet making equipment and the first polarity single-sided sheet making equipment, when the first polarity double-sided sheet making equipment produces a first polarity double-sided electrode sheet and the first polarity single-sided sheet making equipment produces a first polarity single-sided electrode sheet, the two types of electrode sheets can be uniformly transferred to the downstream first cutting mechanism through the first transfer mechanism, so as to cut electrode tabs for the first polarity single-sided electrode sheet and the first polarity double-sided electrode sheet respectively.
[0007] In this process, not only is the first plate-turning mechanism shared, but the first cutting mechanism is also shared. There is no need to configure separate first cutting mechanisms and corresponding installation spaces for the two types of electrode sheets, nor is there a need to configure separate first plate-turning mechanisms and corresponding installation spaces. This reduces the overall footprint of the equipment and improves the utilization rate of the factory space.
[0008] Secondly, the independent wafer fabrication system corresponds to two isolated wafer fabrication paths, resulting in cumbersome material transfer processes, complex path planning, and a tendency for material flow bottlenecks and low collaborative efficiency. This application addresses this by setting up wafer fabrication equipment for two types of electrodes via a first transfer mechanism. This allows the two types of electrodes, after completing their respective wafer fabrication processes, to converge at the same first cutting mechanism, thus merging and simplifying the wafer fabrication paths. This reduces material transfer nodes between equipment, improves the continuity and smoothness of material flow, and lowers the risk of failure during the wafer fabrication process.
[0009] Furthermore, by sharing the first cutting mechanism, the redundant investment in the first cutting mechanism and the first sheet transfer mechanism is reduced, thereby controlling the overall equipment investment and operation and maintenance costs.
[0010] Meanwhile, by ensuring that the number of first polar double-sided sheet making equipment is at least one, the number of first polar double-sided sheet making equipment can be flexibly configured according to actual production capacity requirements and product model requirements. Furthermore, when adding a new first polar double-sided sheet making equipment, there is no need to modify the existing first sheet transfer mechanism and the first cutting mechanism's flow path and core structure, making it more adaptable.
[0011] Furthermore, since single-sided electrodes typically require only the top and bottom two sheets during cell manufacturing, while the demand for double-sided electrodes is far greater, sharing the first transfer mechanism and the first cutting mechanism offers several advantages. First, single-sided electrodes occupy these mechanisms for relatively less time, preventing congestion and interference with the high-demand double-sided electrode flow and cutting processes. This ensures that the double-sided electrodes produced by the first polarity double-sided electrode manufacturing equipment can efficiently reach subsequent processes, guaranteeing a stable overall production cycle. Second, this difference in usage and the compatible combination of shared equipment result in a more balanced load distribution on the first transfer mechanism and the first cutting mechanism, preventing prolonged idleness or overload operation, extending equipment lifespan, and further enhancing cost control.
[0012] Optionally, the first polarity double-sided sheet making equipment is used to make a first polarity double-sided electrode sheet, the first polarity single-sided sheet making equipment is used to make a first polarity single-sided electrode sheet, and the first sheet turning mechanism is used to move the first polarity double-sided electrode sheet and the first polarity single-sided electrode sheet to the first cutting mechanism respectively.

A main road turntable assembly, which is located downstream of the branch road turntable assembly.
[0021] Optionally, the second film-making system and the first film-making system are arranged side by side at a distance along the second direction.
[0022] Optionally, the second film production system includes: At least one second-polarity double-sided film-making device; and, The second cutting mechanism is located downstream of the second polar double-sided sheet making equipment, and the second cutting mechanism and the second polar double-sided sheet making equipment are arranged at intervals along the first direction.
[0023] Optionally, the second film production system further includes: A diaphragm laminating mechanism is located downstream of the second cutting mechanism. The second polarity double-sided sheet making equipment is used to make a second polarity double-sided electrode sheet. The diaphragm laminating mechanism is used to laminate a diaphragm onto both sides of the second polarity double-sided electrode sheet.
[0024] Optionally, the second film production system further includes: The third buffer mechanism is located downstream of the diaphragm composite mechanism.
[0025] Optionally, the stacking device includes: At least two stacking platforms are arranged side by side at intervals along the second direction.
[0026] Optionally, the integrated cutting and stacking machine further includes: A hot pressing device is located downstream of the stacking device, and the hot pressing device is located along a first direction on the side of the stacking device away from the first film-making system.
[0027] Optionally, the hot pressing device includes: At least two hot pressing platforms are arranged side by side at intervals along the first direction; A first transport mechanism, wherein the transport head of the first transport mechanism moves between at least two thermopressing platforms.
[0028] Optionally, at least one of the two hot pressing platforms is a pre-pressing platform; The hot pressing device further includes a fourth buffer mechanism, wherein the transport head of the first transport mechanism moves between at least two hot pressing platforms and the fourth buffer mechanism.
[0029] Optionally, the integrated cutting and stacking machine further includes: The feeding mechanism is located downstream of the hot pressing equipment.
[0030] Compared with the prior art, the beneficial effects of this application are as follows: In this application, since the first transfer mechanism is set up corresponding to the first polarity single-sided sheet making equipment and the first polarity double-sided sheet making equipment, and the first transfer mechanism is located downstream of the first polarity double-sided sheet making equipment and the first polarity single-sided sheet making equipment, when the first polarity double-sided sheet making equipment produces a first polarity double-sided electrode sheet and the first polarity single-sided sheet making equipment produces a first polarity single-sided electrode sheet, the two types of electrode sheets can be uniformly transferred to the downstream first cutting mechanism through the first transfer mechanism, so as to cut electrode tabs for the first polarity single-sided electrode sheet and the first polarity double-sided electrode sheet respectively.
[0031] In this process, not only is the first plate-turning mechanism shared, but the first cutting mechanism is also shared. There is no need to configure separate first cutting mechanisms and corresponding installation spaces for the two types of electrode sheets, nor is there a need to configure separate first plate-turning mechanisms and corresponding installation spaces. This reduces the overall footprint of the equipment and improves the utilization rate of the factory space.
[0032] Secondly, the independent wafer fabrication system corresponds to two isolated wafer fabrication paths, resulting in cumbersome material transfer processes, complex path planning, and a tendency for material flow bottlenecks and low collaborative efficiency. This application addresses this by setting up wafer fabrication equipment for two types of electrodes via a first transfer mechanism. This allows the two types of electrodes, after completing their respective wafer fabrication processes, to converge at the same first cutting mechanism, thus merging and simplifying the wafer fabrication paths. This reduces material transfer nodes between equipment, improves the continuity and smoothness of material flow, and lowers the risk of failure during the wafer fabrication process.
[0033] Furthermore, by sharing the first cutting mechanism, the redundant investment in the first cutting mechanism and the first sheet transfer mechanism is reduced, thereby controlling the overall equipment investment and operation and maintenance costs.
[0034] Meanwhile, by ensuring that the number of first polar double-sided sheet making equipment is at least one, the number of first polar double-sided sheet making equipment can be flexibly configured according to actual production capacity requirements and product model requirements. Furthermore, when adding a new first polar double-sided sheet making equipment, there is no need to modify the existing first sheet transfer mechanism and the first cutting mechanism's flow path and core structure, making it more adaptable.
[0035] Furthermore, since single-sided electrodes typically require only the top and bottom two sheets during cell manufacturing, while the demand for double-sided electrodes is far greater, sharing the first transfer mechanism and the first cutting mechanism offers several advantages. First, single-sided electrodes occupy these mechanisms for relatively less time, preventing congestion and interference with the high-demand double-sided electrode flow and cutting processes. This ensures that the double-sided electrodes produced by the first polarity double-sided electrode manufacturing equipment can efficiently reach subsequent processes, guaranteeing a stable overall production cycle. Second, this difference in usage and the compatible combination of shared equipment result in a more balanced load distribution on the first transfer mechanism and the first cutting mechanism, preventing prolonged idleness or overload operation, extending equipment lifespan, and further enhancing cost control.

[0044] Before explaining the technical solution of this application, the background technology of this application shall be explained first.
[0045] Battery cells typically employ a configuration of an upper single-sided cell, a positive double-sided cell, a negative double-sided cell, and a lower single-sided cell. Because single-sided and double-sided cells are different types, related technologies employ separate manufacturing systems for each.
[0046] However, equipping single-sided and double-sided wafers with separate wafer fabrication systems would occupy a significant amount of factory space, complicate the wafer fabrication path, and increase equipment costs. Therefore, this application provides a novel integrated slitting and stacking machine to address these issues.
[0047] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.
[0048] Figure 1This is a schematic diagram of the structure of a first film-making system 100 provided in an embodiment of this application.
[0049] See Figure 1 The first film-making system 100 includes a first polar single-sided film-making device 1, at least one first polar double-sided film-making device 2, a first film-transferring mechanism 3, and a first cutting mechanism 4. The first film-transferring mechanism 3 is arranged corresponding to the first polar single-sided film-making device 1 and the first polar double-sided film-making device 2, and the first film-transferring mechanism 3 is located downstream of the first polar double-sided film-making device 2 and the first polar single-sided film-making device 1. The first cutting mechanism 4 is located downstream of the first film-transferring mechanism 3.
[0050] The first polarity double-sided sheet making equipment 2 is used to make a first polarity double-sided electrode sheet, the first polarity single-sided sheet making equipment 1 is used to make a first polarity single-sided electrode sheet, the first sheet turning mechanism 3 is used to move the first polarity double-sided electrode sheet and the first polarity single-sided electrode sheet to the first cutting mechanism 4 respectively, and the first cutting mechanism 4 is used to cut electrode tabs from the first polarity single-sided electrode sheet and the first polarity double-sided electrode sheet.
[0051] In this embodiment, since the first transfer mechanism 3 is provided for the first polarity single-sided sheet making equipment 1 and the first polarity double-sided sheet making equipment 2, and the first transfer mechanism 3 is located downstream of the first polarity double-sided sheet making equipment 2 and the first polarity single-sided sheet making equipment 1, when the first polarity double-sided sheet making equipment 2 produces a first polarity double-sided electrode sheet and the first polarity single-sided sheet making equipment 1 produces a first polarity single-sided electrode sheet, the two types of electrode sheets can be uniformly transferred to the downstream first cutting mechanism 4 through the first transfer mechanism 3, so as to cut electrode tabs for the first polarity single-sided electrode sheet and the first polarity double-sided electrode sheet respectively.
[0052] In this process, not only is the first rotating plate mechanism 3 shared, but the first cutting mechanism 4 is also shared. There is no need to configure separate first cutting mechanisms 4 and corresponding installation spaces for the two types of electrode sheets, nor is there a need to configure separate first rotating plate mechanisms 3 and corresponding installation spaces. This reduces the overall footprint of the equipment and improves the utilization rate of the factory space.
[0053] Secondly, the independent wafer fabrication system corresponds to two isolated wafer fabrication paths, resulting in cumbersome material transfer and complex path planning, which can easily lead to material flow bottlenecks and low collaborative efficiency. This application addresses this by setting up wafer fabrication equipment for the two types of electrodes through the first transfer mechanism 3. After completing their respective wafer fabrication processes, the two types of electrodes converge at the same first cutting mechanism 4 via the same first transfer mechanism 3, thereby merging and simplifying the wafer fabrication paths, reducing material transfer nodes between equipment, improving the continuity and smoothness of material flow, and reducing the risk of failure during the wafer fabrication process.
[0054] Furthermore, by sharing the first cutting mechanism 4, the redundant investment in the first cutting mechanism 4 and the first sheet-turning mechanism 3 is reduced, thereby controlling the overall equipment investment and maintenance costs.
[0055] Meanwhile, by ensuring that the number of first polar double-sided sheet making equipment 2 is at least one, the number of first polar double-sided sheet making equipment 2 can be flexibly configured according to actual production capacity requirements and product model requirements. Furthermore, when adding a new first polar double-sided sheet making equipment 2, there is no need to modify the existing first sheet transfer mechanism 3 and first cutting mechanism 4's sheet flow path and core structure, making it more adaptable.
[0056] Furthermore, since single-sided electrodes typically require only the top and bottom two sheets during cell manufacturing, while the demand for double-sided electrodes is far greater, sharing the first transfer mechanism 3 and the first cutting mechanism 4 ensures that, on the one hand, single-sided electrodes occupy these mechanisms for relatively less time, preventing congestion and interference with the high-demand flow and cutting processes of double-sided electrodes. This ensures that the double-sided electrodes produced by the first polarity double-sided electrode manufacturing equipment 2 can efficiently reach subsequent processes, guaranteeing a stable overall production cycle. On the other hand, this difference in usage and the compatible combination of shared equipment result in a more balanced load distribution between the first transfer mechanism 3 and the first cutting mechanism 4, preventing long-term idleness or overload operation, thus extending equipment lifespan and further enhancing cost control.
[0057] The first cutting mechanism 4 mentioned above can be a mechanism that cuts single-sided and double-sided electrode sheets by laser cutting to create electrode tabs on the two types of electrode sheets.
[0058] Specifically, the first cutting mechanism 4 can be a laser cutting machine, a die-cutting machine, or any other mechanism capable of cutting the electrode sheet; this embodiment does not limit this.
[0059] In addition to cutting electrode tabs, the first cutting mechanism 4 described above can also be used to cut V-angles, etc. This embodiment does not limit this.
[0060] It should be noted that in some embodiments, see [reference]. Figure 4 , Figure 4 This is a schematic diagram of another first film-making system 100 provided in one embodiment of this application. The aforementioned at least one first polarity double-sided film-making device 2 may include a complete first polarity double-sided film-making device 21 and a three-quarters first polarity double-sided film-making device 22. Of course, the aforementioned at least one first polarity double-sided film-making device 2 may also include other types and numbers of first polarity double-sided film-making devices, which is not limited in this embodiment. The aforementioned first polarity may be a positive electrode or a positive electrode, etc., which is not limited in this embodiment.
[0061] The aforementioned single-sided electrode is a type of battery cell electrode, referring to an electrode in which active material is coated only on one side of the current collector, while the other side remains uncoated. The aforementioned double-sided electrode refers to an electrode in which active material is coated on both sides of the current collector.
[0062] Specifically, in some embodiments, see [link to relevant documentation]. Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the structure of the first polarity single-sided sheet making equipment 1 is shown. The first polarity single-sided sheet making equipment 1 may include a single-sided sheet unwinding mechanism 11 and a cutting mechanism 12. The single-sided sheet unwinding mechanism 11 can unwind the first polarity single-sided sheet to the cutting mechanism 12, and the cutting mechanism 12 can cut the first polarity single-sided sheet into sheet-like structures.
[0063] In some embodiments, see Figure 3 and Figure 4 , Figure 3 yes Figure 1 The first film transfer mechanism 3 is shown in the schematic diagram. The first film transfer mechanism 3 includes a branch film transfer assembly 31 and a main film transfer assembly 32. At least one of the first polar single-sided film making equipment 1 and the first polar double-sided film making equipment 2 is provided with a branch film transfer assembly 31. The main film transfer assembly 32 is located downstream of the branch film transfer assembly 31.
[0064] By providing branch transfer components 31 for at least one of the first polarity single-sided wafer fabrication equipment 1 and the first polarity double-sided wafer fabrication equipment 2, and by positioning the main transfer component 32 downstream of the branch transfer components 31, single-sided wafers can be transferred to the main transfer component 32 for further transfer via the branch transfer components 31 corresponding to the first polarity single-sided wafer fabrication equipment 1, and double-sided wafers can be transferred to the main transfer component 32 for further transfer via the branch transfer components 31 corresponding to the first polarity double-sided wafer fabrication equipment 2. In other words, single-sided and double-sided wafers can be combined and transferred to the main transfer component 32 for further transfer. From a structural perspective, a single main transfer component 32 can be shared, thereby making the structure of the first transfer mechanism 3 more compact and reducing costs.
[0065] In some embodiments, see Figure 3 The branch conveyor assembly 31 may include a conveyor belt and a handling mechanism, etc. The specific structure of the branch conveyor assembly 31 is not limited in this embodiment. Similarly, the structure of the main conveyor assembly 32 can be similar to that of the branch conveyor assembly 31, and will not be described in detail here.
[0066] In some embodiments, see Figure 1The first film production system 100 also includes a first correction and positioning mechanism 5, which is located downstream of the first film transfer mechanism 3 and upstream of the first cutting mechanism 4.
[0067] By adding a first correction and positioning mechanism 5 and placing it downstream of the first sheet-turning mechanism 3 and upstream of the first cutting mechanism 4, the processing accuracy and product qualification rate of the first cutting mechanism 4 can be improved.
[0068] Specifically, during the transfer of single-sided and double-sided electrodes of the first polarity by the first transfer mechanism 3, the electrodes may experience positional shifts or skewed postures due to factors such as material conveying tension and equipment vibration. If these electrodes directly enter the first cutting mechanism 4, it can easily lead to deviations in the electrode tab cutting dimensions and misalignment, affecting the cell assembly accuracy and electrical performance. The first correction and positioning mechanism 5 can correct the position and posture of the two types of electrodes transferred by the first transfer mechanism 3, precisely adjusting the electrode placement and travel angle to ensure that the electrodes enter the first cutting mechanism 4 in a standard posture. This provides precise positioning assurance for the subsequent electrode tab cutting process, significantly reducing the risk of cutting deviations and improving electrode tab size consistency and cutting pass rate.
[0069] Meanwhile, the first correction and positioning mechanism 5 can also indirectly optimize overall production stability. It can correct electrode misalignment in advance, avoid material jamming and uneven wear of the cutting blade in the first cutting mechanism 4 due to electrode misalignment, reduce the frequency of equipment downtime for maintenance, ensure continuous and smooth wafer fabrication process, and further improve production efficiency.
[0070] It should be noted that there are multiple ways to implement the first correction and positioning mechanism 5. In one possible implementation, the first correction and positioning mechanism 5 may include a position detection component and an attitude adjustment component. The position detection component may use devices such as vision sensors and photoelectric sensors to collect the position information of the electrode sheet transferred by the first rotating plate mechanism 3 in real time, accurately identify whether the electrode sheet has problems such as lateral offset, longitudinal misalignment or attitude distortion, and transmit the detection signal to the attitude adjustment component.
[0071] The attitude adjustment component can be equipped with guide rollers, fine-tuning drive components and other structures. Based on the signal feedback from the position detection component, the electrode sheet is fine-tuned in real time. By adjusting the angle of the guide rollers or driving the electrode sheet to move laterally and longitudinally, the traveling attitude and placement position of the electrode sheet are corrected to ensure that the electrode sheet is transported to the first cutting mechanism 4 in a preset reference attitude.
[0072] Of course, the first correction and positioning mechanism 5 can also be implemented in other possible ways, and this embodiment does not limit it.
[0073] In some embodiments, see Figure 1The first film production system 100 also includes a first buffer mechanism 6, which is located downstream of the first film transfer mechanism 3 and upstream of the first cutting mechanism 4.
[0074] When the first film production system 100 also includes a first buffer mechanism 6, by setting the first buffer mechanism 6 downstream of the first film transfer mechanism 3 and upstream of the first cutting mechanism 4, the film transfer rhythm can be effectively adjusted, and the stability and fault tolerance of the system operation can be improved.
[0075] Specifically, the electrode sheets (including first polarity single-sided and double-sided electrode sheets) transferred by the first transfer mechanism 3 may experience uneven material conveying due to fluctuations in the production cycle of the first polarity single-sided electrode sheet making equipment 1 and the first polarity double-sided electrode sheet making equipment 2. If directly conveyed to the first cutting mechanism 4, it can easily lead to material interruption or material accumulation in the cutting process, affecting production continuity. The first buffer mechanism 6 can play a buffering and regulating role. When the front-end material conveying speed is faster than the processing speed of the first cutting mechanism 4, the buffer mechanism can temporarily store excess electrode sheets to avoid material congestion. When the front-end conveying speed lags behind, the buffer mechanism can release the pre-stored electrode sheets to ensure continuous material supply to the first cutting mechanism 4 and achieve cycle matching between the front and rear processes.
[0076] The first buffer mechanism 6 can be a material buffer platform. The electrode sheets (single-sided electrode sheets and / or double-sided electrode sheets) on the first transfer mechanism 3 can be transferred to the first buffer mechanism 6 by a robotic arm or other possible means.
[0077] It is understandable that when the first correction and positioning mechanism 5 corrects the position and attitude of the electrode sheets, it relies on the uniform and stable transport of the electrode sheets. If there are speed fluctuations or other problems in the front-end electrode sheet transport, it will interfere with the accuracy of the correction detection and the timeliness of the adjustment, affecting the correction effect. Based on this, in some embodiments, see... Figure 1 The first cache mechanism 6 is located upstream of the first correction and positioning mechanism 5.
[0078] By positioning the first buffer mechanism 6 upstream of the first correction and positioning mechanism 5, the upstream first buffer mechanism 6 can first buffer and adjust the electrode sheets transferred from the first transfer mechanism 3, eliminating the uneven material conveying caused by fluctuations in the production cycle and fine adjustments in the transfer speed. This allows the electrode sheets to be conveyed to the downstream first correction and positioning mechanism 5 at a uniform and stable speed, avoiding correction deviations caused by unstable material supply and ensuring that the correction and positioning mechanism can accurately identify electrode sheet offset problems and efficiently correct them.
[0079] On the other hand, if the first buffer mechanism 6 is located downstream of the first alignment and positioning mechanism 5, when the first alignment and positioning mechanism 5 malfunctions and needs to be shut down for maintenance, the electrode sheets transferred by the first transfer mechanism 3 at the front end cannot be received in time, which can easily lead to material accumulation or forced shutdown of the front-end equipment. However, by placing the first buffer mechanism 6 upstream, when the first alignment and positioning mechanism 5 malfunctions and shuts down, the first buffer mechanism 6 can temporarily store the electrode sheets transferred at the front end, avoiding electrode waste and stagnation in the front-end transfer process. After the alignment mechanism resumes operation, it can be smoothly fed, achieving isolation and protection between the buffer and alignment processes, and reducing the impact of local failures on the overall process.
[0080] Of course, in other embodiments, the first buffer mechanism 6 may also be located downstream of the first correction and positioning mechanism 5, and the embodiments do not limit this.
[0081] The electrode sheets cut by the first cutting mechanism 4 need to have their orientation adjusted according to the requirements of the subsequent cell stacking process. This is especially important for single-sided electrode sheets, which are coated with active material on only one side. The accuracy of the orientation directly determines the stability of the cell's electrical performance. Specifically, it may be necessary to have the side of the bottom single-sided electrode sheet coated with active material facing upwards, and the side of the top single-sided electrode sheet coated with active material facing downwards. Considering this, in some embodiments, see... Figure 1 The first film production system 100 also includes a flipping mechanism 7, which is located downstream of the first cutting mechanism 4.
[0082] By positioning the flipping mechanism 7 downstream of the first cutting mechanism 4, the electrode sheet that has undergone tab cutting by the first cutting mechanism 4 can be automatically and selectively flipped by the flipping mechanism 7. This allows for precise control of the electrode sheet's posture without manual intervention, thus avoiding the risk of posture deviation caused by manual adjustment and significantly reducing manual operation costs.
[0083] The aforementioned flipping mechanism 7 can be implemented in several ways. In one possible implementation, the flipping mechanism 7 may include an attitude detection component and a flipping drive component. The attitude detection component may employ a vision sensor to identify the current orientation and attitude of the electrode sheet in real time, determine whether it meets the requirements of subsequent processes, and transmit the detection signal to the flipping drive component. The flipping drive component may employ a rotating gripper, a flipping cylinder, or other structures. Based on the signal feedback from the attitude detection component, it precisely flips the electrode sheet whose orientation needs to be adjusted. The flipping angle can be set as needed to 180°. After flipping, the electrode sheet can be smoothly transported to subsequent processes, achieving automated and precise control of the electrode sheet orientation without manual intervention.
[0084] Of course, the flipping mechanism 7 can also be other possible structures, and this embodiment does not limit it.
[0085] In some embodiments, see Figure 1The first film production system 100 also includes a coding mechanism 8, which is located downstream of the first cutting mechanism 4 and upstream of the flipping mechanism 7.
[0086] When the first electrode manufacturing system 100 also includes a coding mechanism 8, the coding mechanism 8 can be used to code the electrode sheets cut by the first cutting mechanism 4. The coding can mark specific information (such as production batch, process parameters, quality inspection results, etc.) to provide data support for subsequent cell assembly, finished product testing, and after-sales traceability. By positioning the coding mechanism 8 downstream of the first cutting mechanism 4 and upstream of the flipping mechanism 7, coding can be performed after the electrode sheet posture is stable and the dimensions are finalized, avoiding the situation where coding before electrode sheet cutting is affected by subsequent processes, resulting in blurred markings or positional shifts.
[0087] Since the single-sided electrode is usually located on the outermost layer of the battery cell, the coding mechanism 8 can code on the single-sided electrode during actual coding. In this way, the advantage of the outer layer position of the single-sided electrode allows the coding mark to be directly exposed on the surface of the battery cell. In subsequent process inspections, finished product outbound verification, and after-sales problem tracing, the coding information can be quickly read without disassembling the battery cell, which greatly simplifies the traceability process and improves management efficiency.
[0088] It should be noted that the aforementioned marking mechanism 8 can be a laser marking machine, an inkjet marking machine, or an electrochemical marking machine, which can be flexibly selected according to the electrode material, marking accuracy requirements, and production cycle.
[0089] It should also be noted that the above-mentioned coding mechanism 8 being located downstream of the first cutting mechanism 4 and upstream of the flipping mechanism 7 is only one possible setting position of the coding mechanism 8 given in this embodiment. It is only necessary to make the coding mechanism 8 downstream of the first polar single-sided sheet making equipment 1 and downstream of the first polar double-sided sheet making equipment 2. This embodiment does not limit this.
[0090] For example, the coding mechanism 8 can be located downstream of the first sheet-turning mechanism 3 or upstream of the first cutting mechanism 4, etc. This embodiment does not limit this.
[0091] In some embodiments, see Figure 1 The first film-making system 100 also includes a second buffer mechanism 9, which is located downstream of the first cutting mechanism 4. The second buffer mechanism 9 can be used to buffer double-sided electrode films. Specifically, the second buffer mechanism 9 and the flipping mechanism 7 can be arranged in parallel downstream of the first cutting mechanism 4.
[0092] As mentioned earlier, double-sided electrodes are in much greater demand than single-sided electrodes in cell manufacturing and are the mainstream material for electrode processing. By positioning the second buffer mechanism 9 downstream of the first cutting mechanism 4, the second buffer mechanism 9 can independently receive double-sided electrodes cut by the first cutting mechanism 4, while the flipping mechanism 7 can specifically receive single-sided electrodes. In this way, double-sided electrodes and single-sided electrodes can be separated, avoiding material supply chaos caused by the mixed storage of the two types of electrodes.
[0093] Meanwhile, the second buffer mechanism 9 is specifically designed to buffer bifacial electrodes, precisely matching the high-volume production needs of bifacial electrodes. When the number of bifacial electrodes output by the first cutting mechanism 4 exceeds the processing capacity of downstream processes, the second buffer mechanism 9 can temporarily store the excess bifacial electrodes, preventing material accumulation and congestion. When downstream processes need to increase their processing speed, this mechanism can quickly release the pre-stored bifacial electrodes, ensuring continuous material supply without relying on adjustments to the speed of the front-end processes, thus improving the flexibility of the overall production cycle.
[0094] In addition, separately buffering the bifacial electrode can reduce its contact friction with the single-sided electrode, reduce the risk of damage to the active material on the electrode surface, and ensure the product quality of the bifacial electrode.
[0095] It should be noted that the structure of the second cache mechanism 9 can be the same as or similar to that of the first cache mechanism 6. For details, please refer to the description of the first cache mechanism 6 in the above embodiments. This embodiment will not repeat the description here.
[0096] In some embodiments, see Figure 1 The first polarity single-sided sheet making equipment 1, the first polarity double-sided sheet making equipment 2, and the first cutting mechanism 4 are along the first direction ( Figure 1 Arranged side-by-side at intervals along the X-axis.
[0097] By arranging the first polar single-sided sheet making equipment 1, the first polar double-sided sheet making equipment 2, and the first cutting mechanism 4 side by side at intervals along the first direction, the layout of the three equipment along the first direction can be made relatively regular. On the one hand, it can simplify the layout difficulty of the first polar single-sided sheet making equipment 1, the first polar double-sided sheet making equipment 2, and the first cutting mechanism 4. On the other hand, it can reduce the space occupied by the first polar single-sided sheet making equipment 1, the first polar double-sided sheet making equipment 2, and the first cutting mechanism 4 in the factory to a certain extent.
[0098] Of course, in other embodiments, the first polar single-sided sheet making device 1, the first polar double-sided sheet making device 2 and the first cutting mechanism 4 may also be arranged in a staggered manner along the first direction, and this embodiment does not limit this.
[0099] One embodiment of this application also provides a cutting and stacking integrated machine 200, see [link]. Figure 5 , Figure 5This is a schematic diagram of the structure of a slicing and stacking machine 200 provided in an embodiment of this application. The slicing and stacking machine 200 includes a first film preparation system 100 and a second film preparation system 20, wherein the second film preparation system 20 and the first film preparation system 100 are aligned along a second direction ( Figure 5 Arranged side-by-side at intervals in the Z-axis direction.
[0100] The first film-making system 100 can be the first film-making system 100 described in the above embodiments. Its specific structure can be the same as or similar to the structure of any of the first film-making systems 100 described in the above embodiments. For details, please refer to the description in the above embodiments. This embodiment will not repeat the description here.
[0101] By arranging the second electrode fabrication system 20 and the first electrode fabrication system 100 side by side at intervals along the second direction, parallel processing of electrode sheets can be achieved. The first electrode fabrication system 100 and the second electrode fabrication system 20 can respectively process electrode sheets of different polarities and types, which greatly shortens the overall processing cycle and adapts to the needs of mass production of battery cells. At the same time, it is convenient to stack the electrode sheets produced by the first electrode fabrication system 100 and the electrode sheets produced by the second electrode fabrication system 20 to make battery cells.
[0102] Meanwhile, the parallel layout along the second direction allows the material flow paths of the two first-stage wafer fabrication systems to be independent and close to each other. This facilitates the centralized collection and integration of electrode sheets produced by the two systems in subsequent cell stacking processes, reducing electrode sheet transfer distances and the risk of secondary handling. In addition, the compact and independent layout saves factory space, facilitates centralized equipment management and maintenance, reduces operating costs, and reserves ample space for future expansion of the production line, improving the overall system's scalability and adaptability.
[0103] The second direction differs from the first direction; specifically, the second direction and the first direction can be perpendicular to each other.
[0104] By making the second direction different from the first direction, the overall spatial layout of the cutting and stacking machine 200 can be made more reasonable, forming a three-dimensional, staggered equipment arrangement structure, effectively avoiding the problem of overlapping or interference in equipment layout.
[0105] Specifically, the first direction is the arrangement direction of the first polarity single-sided sheet forming equipment 1, the first polarity double-sided sheet forming equipment 2, and the first cutting mechanism 4, emphasizing the vertical flow connection of electrode processing. The second direction (perpendicular to the first direction) is the arrangement direction of the dual first sheet forming systems, emphasizing the horizontal parallel arrangement of the two processing links. This vertical layout maximizes the use of factory space, accommodating more processing components in a limited area, while ensuring that the material flow paths of the two first sheet forming systems do not intersect, avoiding collisions or interference during electrode transfer, and improving overall operational safety.
[0106] Understandably, since the first film production system 100 occupies a smaller overall area, it improves the utilization rate of factory space. Therefore, when the cutting and stacking machine 200 includes the first film production system 100, the overall area of the cutting and stacking machine 200 can be reduced, thus improving the utilization rate of factory space.
[0107] In some embodiments, see Figure 4 The second film-making system 20 includes at least one second polar double-sided film-making device 201 and a second cutting mechanism 202, wherein the second cutting mechanism 202 is located downstream of the second polar double-sided film-making device 201, and the second cutting mechanism 202 and the second polar double-sided film-making device 201 are along a first direction ( Figure 5 Arranged at intervals along the X-axis.
[0108] The structure of the second polar double-sided sheet making device 201 can be the same as or similar to the structure of the first polar double-sided sheet making device 2 described above. For details, please refer to the description of the first polar double-sided sheet making device 2 in the above embodiments; it will not be repeated here. The structure of the second cutting mechanism 202 can be the same as or similar to the structure of the first cutting mechanism 4. For details, please refer to the description in the above embodiments; it will not be repeated here either.
[0109] By arranging the second cutting mechanism 202 and the second polar double-sided sheet making equipment 201 at intervals along the first direction, the second sheet making system 20 can form a regular longitudinal processing link, which can ensure the symmetry of the process of the two systems, facilitate the synchronous processing cycle, lay the foundation for subsequent electrode assembly, and optimize the overall layout regularity and reduce pipeline cross-interference.
[0110] It should be noted that the second polarity mentioned above is different from the first polarity. When the first polarity is negative, the second polarity can be positive, and when the first polarity is positive, the second polarity can be negative.
[0111] In some embodiments, see Figure 5 The second cutting mechanism 202 may include a primary cutting mechanism 2021 and a secondary cutting mechanism 2022.
[0112] By making the second cutting mechanism 202 include a primary cutting mechanism 2021 and a secondary cutting mechanism 2022, the primary cutting mechanism 2021 can undertake the initial length cutting task of the electrode tab, quickly remove excess material from the electrode sheet, and regularize the basic outline of the electrode tab, laying the foundation for subsequent precise cutting. At the same time, it adapts to the front-end electrode sheet conveying rhythm and avoids the problem of low efficiency caused by single high-precision cutting.
[0113] The secondary cutting mechanism 2022 can precisely trim, fine-tune the size and optimize the flatness of the tabs after the first cutting, effectively making up for the slight size deviations in the first cutting process, greatly improving the consistency of tab size, edge flatness and position accuracy, and avoiding the tab size deviation from affecting the battery cell tab docking accuracy and electrical performance stability.
[0114] It should be noted that the primary cutting mechanism 2021 and the secondary cutting mechanism 2022 described above can also be applied in other possible scenarios. For example, the primary cutting mechanism 2021 can be used to cut tabs, and the secondary cutting mechanism 2022 can be used to cut V-angles, etc. This embodiment does not limit this.
[0115] In some embodiments, see Figure 5 The second film-making system 20 also includes a diaphragm composite mechanism 203, which is located downstream of the second cutting mechanism 202. The second polarity double-sided film-making equipment 201 is used to make a second polarity double-sided electrode sheet, and the diaphragm composite mechanism 203 is used to composite diaphragms on both sides of the second polarity double-sided electrode sheet.
[0116] Both sides of the second polarity double-sided electrode are coated with active material. In the cell stacking process, it needs to be stacked alternately with the first polarity electrode. By bonding a separator to both sides of the second polarity double-sided electrode, the separator can directly serve as an isolation barrier between the two polarities, effectively blocking direct contact between the two active materials, thus avoiding the risk of short circuit from the source and ensuring the safety of cell use.
[0117] Meanwhile, the diaphragm is pre-composite on both sides of the second polarity double-sided electrode, which can replace the process of laying the diaphragm separately during the traditional stacking process. This avoids the problem of isolation failure caused by diaphragm displacement and wrinkles during the stacking process, ensuring the integrity and stability of the isolation, while protecting the surface active material of the electrode from wear and shedding, and ensuring the stability of the electrode's electrical performance.
[0118] The diaphragm composite mechanism 203 can be implemented in various ways. In one possible implementation, see [link to relevant documentation]. Figure 5 The diaphragm lamination mechanism 203 may include a diaphragm unwinding assembly 2031, a pressing assembly 2032, and a cutting assembly 2033. The diaphragm unwinding assembly 2031 is disposed on both sides of the electrode conveying path, providing diaphragms for lamination onto both sides of the electrode. The pressing assembly 2032 adopts a hot-pressing or cold-pressing structure to tightly bond the diaphragms on both sides to the electrode, ensuring lamination strength. The cutting assembly 2033 is used to cut off excess diaphragms.
[0119] In some embodiments, see Figure 5 The second film production system 20 also includes a third buffer mechanism 204, which is located downstream of the diaphragm composite mechanism 203.
[0120] The second polarity double-sided electrode sheet, after being processed by the diaphragm composite mechanism 203, has completed the double-sided diaphragm composite. Its surface diaphragm must be protected from displacement or damage caused by collision or friction. The third buffer mechanism 204 can provide a dedicated buffer space for this type of electrode sheet, reduce electrode sheet stacking, squeezing and contact damage, and ensure the diaphragm composite accuracy and the overall integrity of the electrode sheet.
[0121] Meanwhile, the third buffer mechanism 204 can match the cycle time of the composite electrode with that of the downstream process. When the cycle time of the downstream stacking process slows down, this mechanism can temporarily store the composited electrode to prevent the front-end separator composite mechanism 203 from being forced to stop due to material accumulation, thus maintaining the continuity of the front-end process.
[0122] When downstream processes accelerate, pre-stored electrode sheets can be quickly released to ensure sufficient material supply without adjusting the operating parameters of the diaphragm composite mechanism 203, thus improving the overall process coordination flexibility. Furthermore, the dedicated buffer enables the orderly output of composited electrode sheets, avoiding material supply chaos caused by mixing with other types of electrode sheets. This lays a well-organized material foundation for subsequent stacking with the electrode sheets from the first electrode fabrication system 100, further simplifying the production line connection process.
[0123] The structure of the third cache mechanism 204 can be the same as or similar to that of the first cache mechanism 6. For details, please refer to the description of the first cache mechanism 6 in the above embodiments. This embodiment will not repeat the description here.
[0124] In some embodiments, see Figure 5 The integrated cutting and stacking machine 200 also includes a stacking device 30, which is set in relation to the first film production system 100 and the second film production system 20, and is located downstream of the first film production system 100 and the second film production system 20.
[0125] By placing the stacking equipment 30 downstream of the first wafer fabrication system 100 and the second wafer fabrication system 20, the stacking equipment 30 can be connected to the first wafer fabrication system 100 and the second wafer fabrication system 20. In this way, firstly, the electrode sheets produced by the two systems can be centrally received and orderly connected, without the need to configure stacking equipment for the two first wafer fabrication systems separately, which greatly reduces equipment investment costs, while reducing the space occupied in the factory and optimizing the overall layout of the production line.
[0126] Secondly, the stacking equipment is equipped with a dual-system setup, which can simultaneously receive double-sided electrodes of the first polarity and single-sided electrodes of the first polarity output from the first film preparation system 100, and double-sided electrodes of the second polarity output from the second film preparation system. This facilitates stacking according to the stacking method of "single-sided electrode of the first polarity + double-sided electrode of the second polarity + double-sided electrode of the first polarity + double-sided electrode of the second polarity + single-sided electrode of the first polarity".
[0127] It should be noted that, in some embodiments, multiple layers of single-sided electrodes of the first polarity can be repeatedly stacked between two layers of single-sided electrodes of the first polarity, following the stacking method of double-sided electrodes of the second polarity + double-sided electrodes of the first polarity.
[0128] In some embodiments, see Figure 5 The stacking apparatus 30 includes at least two stacking platforms 301, and the at least two stacking platforms 301 are along a second direction ( Figure 5 Arranged side by side at intervals along the Z-axis.
[0129] By making the stacking device 30 include at least two stacking platforms 301, and making the at least two stacking platforms 301 arranged side by side at intervals along the second direction, from the perspective of spatial adaptation, the stacking platforms 301 arranged along the second direction can correspond to the layout of the dual first wafer fabrication system along the second direction, so that each stacking platform can be specifically connected to the electrode output of the corresponding first wafer fabrication system, shortening the transfer path of the electrode into the platform, reducing the attitude calibration cost, and ensuring the stacking accuracy.
[0130] From a production efficiency perspective, at least two stacking platforms can achieve parallel stacking operations, improving stacking efficiency. On the other hand, it enables process redundancy backup; when one stacking platform is shut down for maintenance or specification change, the other platform can continue operating normally, ensuring uninterrupted stacking operations and improving the overall fault tolerance and continuous operation capability of the production line. Furthermore, the orderly arrangement along the second direction facilitates centralized equipment management and maintenance, reduces pipeline interference, and allows for flexible adjustment of the number of stacking platforms according to capacity requirements, enhancing the scalability of the equipment layout and adapting to different scales of production needs.
[0131] Specifically, see Figure 5 The number of stacking platforms 301 can be two, three, or four, etc., and this embodiment does not limit this.
[0132] In some embodiments, the stacking apparatus 30 may further include a stacking transport mechanism and a stacking correction mechanism. The stacking transport mechanism can transport the electrode sheets to the stacking platform, and the stacking correction mechanism can correct the deviation of the electrode sheets transported to the stacking platform.
[0133] In some embodiments, see Figure 5 The cutting and stacking integrated machine 200 also includes a hot pressing device 40, which is located downstream of the stacking device 30, and the hot pressing device 40 is along a first direction ( Figure 5 The electrode stacking equipment 40 (located on the side of the stacking equipment 30 away from the first electrode preparation system 100) is located in the X-axis direction. The hot pressing equipment 40 can hot press the electrode stacked on the stacking platform 301.
[0134] By positioning the hot pressing equipment 40 along the first direction on the side of the stacking equipment 30 away from the first film-making system 100, this location planning can make full use of the longitudinal (first direction) space of the factory, avoid the layout chaos caused by the concentrated stacking of equipment, and at the same time make the hot pressing equipment 40 and the stacking equipment 30 form a longitudinal continuous process chain, shorten the semi-finished product transfer distance, and reduce energy consumption and transfer losses.
[0135] In addition, the layout away from the first electrode preparation system 100 can reduce the impact of heat from the hot pressing equipment on the front-end electrode processing equipment and materials, prevent the active material of the electrode from being damaged due to temperature fluctuations, and ensure product quality stability.
[0136] In some embodiments, see Figure 5 The hot pressing equipment 40 includes at least two hot pressing platforms 401 and a first conveying mechanism 402, wherein the at least two hot pressing platforms 401 are arranged side by side at intervals along a first direction, and the conveying head of the first conveying mechanism 402 moves between the at least two hot pressing platforms 401.
[0137] By including at least two hot pressing platforms 401 in the hot pressing equipment 40, the at least two hot pressing platforms can realize parallel hot pressing operations. When one platform is performing hot pressing processing, the other platform can complete the loading of semi-finished products or the unloading of finished products, eliminating the waiting gap for loading and unloading in single-platform operation, greatly improving the overall cycle time of the hot pressing process, and forming a precise match with the batch production of the front-end stacking equipment.
[0138] By arranging at least two hot pressing platforms 401 sequentially and side by side along the first direction, the hot pressing platforms arranged along the first direction can be consistent with the overall layout of the hot pressing equipment 40 along the first direction, making the equipment structure more regular, while facilitating the precise movement of the first handling mechanism, shortening the handling path, and improving the transfer efficiency.
[0139] By enabling the transport head of the first transport mechanism 402 to move flexibly between multiple hot pressing platforms, the orderly transfer of semi-finished products and the load balance between platforms can be achieved, avoiding process bottlenecks caused by excessive occupation of a single platform.
[0140] The conveying head can be a gripper or a suction cup, etc., and this embodiment does not limit it.
[0141] In some embodiments, see Figure 5 At least one of the two hot pressing platforms 401 is a pre-pressing platform. Figure 5 The leftmost hot press platform 401 in the middle hot press platform 401), the hot press equipment 40 also includes a fourth buffer mechanism 403, and the transport head of the first transport mechanism 402 moves between at least two hot press platforms 401 and the fourth buffer mechanism 403.
[0142] By making at least one of the at least two hot pressing platforms 401 a pre-pressing platform, pre-pressing can be performed through the pre-pressing platform, and then hot pressing can be performed through the other hot pressing platforms 401, thereby realizing a staged hot pressing process from "pre-pressing and shaping to final pressing and densification".
[0143] Specifically, the pre-pressing platform first performs preliminary hot pressing on the stacked semi-finished products to quickly fix the cell structure and eliminate interlayer gaps. This avoids problems such as diaphragm displacement and electrode misalignment caused by loose structure during the subsequent final pressing process, laying a precise foundation for the final pressing process and significantly improving the structural consistency and density of the final hot-pressed product, thus ensuring the stability of the cell's electrical performance.
[0144] By moving the transport head of the first transport mechanism 402 between at least two hot pressing platforms 401 and the fourth buffer mechanism 403, when there is a difference in the cycle time of the pre-pressing and final pressing platforms, or when the downstream process has insufficient temporary storage capacity, the transport head of the first transport mechanism 402 can transport the pre-pressed semi-finished product or the final pressed product completed by the hot pressing platform 401 to the fourth buffer mechanism 403 for temporary storage, thereby avoiding material accumulation and process stagnation between platforms.
[0145] The structure of the fourth cache mechanism 403 can be the same as or similar to that of the first cache mechanism 6, and will not be described in detail here.
[0146] In some embodiments, see Figure 5 The cutting and stacking machine 200 also includes a feeding mechanism 50, which is located downstream of the hot pressing equipment 40.
[0147] By positioning the feeding mechanism 50 downstream of the hot press equipment 40, the final pressed product completed by the hot press equipment 40 can be fed out through the feeding mechanism 50, eliminating the need for manual feeding. This improves the automation level of the cutting and stacking machine 200 and reduces the labor intensity of personnel.
[0148] Specifically, the feeding mechanism 50 can feed the final pressed product completed by the hot pressing equipment 40 into the tray.
[0149] Of course, in other embodiments, the feeding mechanism 50 may also feed the final pressed product completed by the hot pressing equipment 40 to other locations or processes, and this embodiment does not limit this.
[0150] The aforementioned unloading mechanism 50 can be a unloading robot or other possible structures, and this embodiment does not limit it.
[0151] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
