However, embodiments of the present disclosure can be modified in various different forms and should not be construed as limiting the scope of the concept of the present disclosure to the embodiments described below.

[0041] (First Implementation)

[0042] Figure 1 A conceptual perspective view schematically illustrates the state of an electrode undergoing an electrode manufacturing process.

[0043] Reference Figure 1 The coated electrode 1 is manufactured by coating the entire current collector with an active material in a coater C to form a coated portion 1a. The uncoated portion 1b, without active material, may be marked with reference points. In some embodiments, the active material may be coated on both the top and back surfaces of the electrode 1. The coated electrode 1 may be pressed by a pressure roller in a rolling process and may be cut along the longitudinal direction of the electrode 1 by a slitting process.

[0044] Then, in the grooving process, the electrode tabs 2 can be formed by stamping using a press or similar method. In the grooving process, the electrode tabs 2 are formed as unit electrodes, allowing them to be cut according to the unit electrodes used to manufacture battery cells, or they can be cut in subsequent processes. The width of the unit electrode corresponds to the spacing P processed by the press.

[0045] This electrode manufacturing process is carried out through a series of roll-to-roll processes, in which the electrode unwound from the unwound unit moves and rewinds in the rewinder; in other words, the electrode moves from the unwound unit to the rewinder and is coated, and the electrode is wound in the rewinder to complete the electrode roll for the coating process. Next, the electrode roll is mounted on the unwound unit of the roll forming process and moved to the rewinder in the roll forming process. The electrode roll is wound on the rewinder in the roll forming process, completing the electrode roll as part of the roll forming process. The electrode roll can then be unwound from the unwound unit of a subsequent process (e.g., a second roll forming process, a slitting process, or a grooving process, etc.), and after a predetermined process, it can be rewound on the rewinder of the subsequent process to complete the electrode roll as part of the subsequent process. In this way, the electrode manufacturing process can include a series of roll-to-roll processes in which the electrode roll unwound from the unwound unit moves and rewinds in the rewinder (so-called roll-to-roll processes), and these processes are repeated sequentially.

[0046] Figure 2 A conceptual diagram of a roll pattern generated in an electrode manufacturing process according to an embodiment of the present disclosure is shown.

[0047] As described above, electrodes are manufactured using a roll-to-roll method in processes such as coating, rolling, and slitting. A roll plot simulating this electrode development is shown in bar form. On the roll plot, the longitudinal and width positions of the electrode are shown as coordinates. In other words, the roll plot is defined on a coordinate plane with two axes: the longitudinal axis and the width axis of the electrode. Each position of the electrode on the coordinate plane can be represented by coordinate values ​​on the coordinate plane. In this roll plot, information about defects, quality issues, electrode breakage, etc., occurring during the electrode manufacturing process is stored along with the coordinates, thus facilitating a concise visualization of data related to quality or defects in the electrode manufacturing process.

[0048] Reference Figure 2 The coordinates of the defects are visualized and information about external defects such as pinhole defects f1 and line defects f2 is displayed. Additionally, mismatches between coated and uncoated portions f3 are shown. Other loading defects are also shown, along with discarded portions at the outermost edge of the electrode.

[0049] Furthermore, reference points K1, K2, and K3 can be marked on electrode 1 at predetermined intervals. When electrode 1 breaks and the seam connecting member is attached to the electrode, the electrode length is reduced by the breakage length. As mentioned above, points where external defects occur can also be removed, allowing the operator to connect them. The roll drawing can also simulate this situation and modify the coordinates on the roll drawing. Now refer to Figure 2 As mentioned above, coordinates that do not reflect electrode roll removal and coordinates that do reflect electrode roll removal are shown together in a single roll plot. The former is called the absolute coordinate (x), and the latter is called the relative coordinate (y). Figure 2As shown, relative coordinates (y) and absolute coordinates (x) can be displayed in parallel on a single roll plot, or they can be represented separately. The roll plot labeled with relative coordinates (y) represents the state of the physical electrodes.

[0050] Such roll patterns can be generated for each of the individual processes described above. However, since the electrode wound in the previous process is unwound in the subsequent process, the start and end points of the electrode are reversed in the roll-to-roll process, making the end of the roll pattern representing the electrode roll of the previous process the start of the roll pattern representing the electrode roll of the subsequent process. Furthermore, in the case of double-sided electrodes with the electrode active material coated on both sides, the electrode surfaces can be reversed; for example, the top electrode in the previous process becomes the back electrode in the subsequent process. In other words, the start and end points of the electrode can be reversed, and the surfaces can also be reversed, depending on the winding direction of the electrode in the previous process and the unwinding direction of the electrode in the subsequent process. Since the roll pattern for each process is generated based on these reversed electrodes, the coordinates of the roll pattern for each process are also reversed from each other. Furthermore, the length of the electrode can be changed by repeatedly cutting and joining electrodes in the longitudinal direction, for example, by removing defective or broken sections in a series of roll-to-roll processes. The roll pattern for each process reflects these reversals and length changes, and therefore may have different coordinate values.

[0051] In the final stage of electrode manufacturing, after removing the electrode portions removed in the previous process, only the remaining electrodes (retained electrodes) remain. Since batteries are manufactured using these retained electrodes, if problems arise in the finished or semi-finished batteries, the cause can be traced by referring to the final retained electrode roll diagram. Furthermore, by referring to the roll diagrams for each of the aforementioned processes, the electrode portion where the problem occurred can be identified. Therefore, roll diagrams are a useful tool for quality and defect identification and quality tracking.

[0052] Figure 3 A schematic diagram of a battery manufacturing system according to an embodiment of the present disclosure is shown conceptually.

[0053] Reference Figure 3 The battery manufacturing system includes an electrode processing apparatus 110 for performing electrode processes. In some embodiments, the electrode processing apparatus 110 may be a roll-to-roll processing apparatus.

[0054] The electrode processing apparatus 110 may include an unwinder 1111, a rewinder 1113, a processing machine 1115, a first rotary encoder 1121, a second rotary encoder 1125, an inspection and / or measuring instrument 1130, and a process programmable logic controller (PLC) 1143.

[0055] The unwinder 1111 may be provided with an electrode roll manufactured in a previous electrode process, and the unwinder 1111 may be configured to unwind the electrode roll. The rewinder 1113 may be configured to wind electrode E1, which has been unwound from the unwinder 1111 and processed by the electrode process. The electrode process may be, for example, a coating process, a rolling process, a grooving process, etc., but is not limited to these.

[0056] The first rotary encoder 1121 can be configured to detect the degree to which the electrode has been unwound by the unwounder 1111. The first rotary encoder 1121 can be configured to be contact or non-contact. In some embodiments, the first rotary encoder 1121 can be configured to sense the length of the electrode unwound by the unwounder 1111. Therefore, the first rotary encoder 1121 can be configured to generate an unwound amount signal (UWAS) representing the length of the electrode that has been unwound, and transmit it to the roll plotting PLC 1171, which will be described in more detail below. The roll plotting PLC 1171 can be configured to collect unwound amount data based on the received unwound amount signal (UWAS).

[0057] The second rotary encoder 1125 can be configured to detect the degree to which the electrode is wound by the second rewinder 1113. The second rotary encoder 1125 can be configured as a contact type or a non-contact type. In some embodiments, the second rotary encoder 1125 can be configured to sense the length of the electrode wound by the second rewinder 1113. Therefore, the second rotary encoder 1125 can be configured to generate a winding amount signal (WAS) representing the length of the electrode winding and transmit it to the mapping PLC 1171, which will be described in more detail below. The mapping PLC 1171 can be configured to collect winding amount data based on the received winding amount signal (WAS).

[0058] Inspection and / or measuring instrument 1130 can be configured to inspect and / or measure electrode E1 as it is transferred from unwinder 1111 to rewinder 1113 to collect inspection and / or measurement data (MD) of electrode E1. Depending on the purpose of the measurement, the term "inspection and / or measuring instrument" includes an inspector, measuring instrument, and any or all of inspection and measuring instruments. Furthermore, the term "inspection and / or measurement data" means including any or all of inspection data, measurement data, and inspection / measurement data. Finally, inspection and / or measurement data refers to all data obtainable by inspecting and / or measuring electrodes. Additionally, inspection and / or measuring instrument refers to all mechanisms used to inspect or measure electrodes to obtain specific inspection and / or measurement data.

[0059] The inspection and / or measurement data for electrode E1 mentioned in this disclosure may include data regarding the quality or defects of electrode E1. For example, when the electrode processing apparatus 110 is a coating apparatus, measurement data regarding the electrode slurry loading, inspection data regarding pinhole defects or wire defects, etc., can be obtained. When the loading exceeds a set range, this location can be identified as a defect, and a label can be assigned and / or used for visual display to distinguish it from other parts. The inspection and / or measurement data of this disclosure are not limited to defects, but may also include data regarding quality. For example, specific examples of inspection and / or measurement data that can be obtained in the electrode process are as follows: i) Data regarding at least one of the electrode dimensions and width, ii) Data regarding the mismatch between the coated and uncoated portions of the electrode. iii) Data on the slurry loading on the electrodes, iv) Data regarding electrode appearance, v) Data regarding the location of the electrode fracture section or the connection location between electrodes. vi) Data regarding the location of the sample inspection section. vii) Data regarding the location of abandoned electrode sections viii) Data on insulation quality or defects in the insulating material coating process following electrode paste coating. ix) Other defect data, x) Data regarding reference points marked on the electrodes at predetermined intervals, xi) Data on electrode thickness after rolling.

[0060] In some embodiments, the inspection and / or measuring instrument 1130 can inspect and / or measure the electrode E1 using a scanning method. In some embodiments, the inspection and / or measuring instrument 1130 can move along the width direction of the electrode E1. In some embodiments, during a single scan of the inspection and / or measuring instrument 1130, the inspection and / or measuring instrument 1130 can move from one end of the width direction of the electrode E1 to the other end of the width direction. When the inspection and / or measuring instrument 1130 performs a scan in the width direction, the electrode E1 can be moved in the longitudinal direction of the electrode by the unwinder 1111 and the rewinder 1113.

[0061] The processing machine 1115 can be any processing device capable of performing processes such as coating, rolling, grooving, etc. For example, when Figure 3 When the electrode process shown is a coating process, the processing machine 1115 can be a coater. For example, when Figure 3 When the electrode process shown is a rolling process, the processing machine 1115 can be a rolling device. For example, when Figure 3When the electrode process shown is a grooving process, the processing machine 1115 can be a grooving device.

[0062] In some embodiments, when the processing machine 1115 is a rolling device, the processing machine 1115 may include a pair of rollers configured to apply a predetermined pressure toward each other between electrodes E1.

[0063] In some embodiments, when the processing machine 1115 is a grooving machine, the processing machine 1115 may be a press for grooving, for example, including a drive portion configured to move the grooving die up and down at regular intervals, and when the grooving die moves down, it may punch the edge of the electrode E1 to form a lead tab of a predetermined shape (e.g., rectangular).

[0064] Inspection and / or measurement data (MD) may include inspection results expressed numerically. For example, inspection and / or measurement data (MD) may include the coordinates and dimensions of defective portions on electrode E1. In some embodiments, the inspection and / or measurement data (MD) may also include: data on the amount of coating material loaded on the electrode; dimensional data, such as the width of the insulating material provided on the coating material and the overlap width between the coating material and the insulating material; and mismatch data between the coating strips on the top surface of the electrode and the coating strips on the lower surface of the electrode. Here, the loading amount refers to the amount of coating material loaded per unit area of ​​electrode E1, which may be the area density of the coating material. The inspection and / or measurement data (MD) may be processed in a set manner to determine whether the inspected and / or measured portions of the electrode are acceptable.

[0065] The inspection and / or measuring instrument 1130 may include a sensing unit 1131 and a processing unit 1133. The sensing unit 1131 may be configured to sense a physical quantity of the electrode E1 to generate an inspection and / or measurement signal (MS). For example, the sensing unit 1131 may include a time delay and integration (TDI) camera, a complementary metal-oxide-semiconductor (CMOS) image sensor, a time-of-flight (TOF) sensor, etc. The sensing unit 1131 may also include a transmitter and a receiver configured to perform measurements using non-destructive signals such as ultrasound, microwaves, terahertz waves, infrared light, etc. In some embodiments, the sensing unit 1131 may include analog and / or digital sensors, such as biosensors, chemical sensors, composition sensors, current and / or power meters, air quality sensors, gas sensors, Hall effect sensors, brightness level sensors, optical sensors, etc. In some embodiments, the inspection and / or measuring instrument 1130 may also include pressure sensors, temperature sensors, ultrasonic sensors, proximity sensors, door status sensors, motion tracking sensors, humidity sensors, visible light and infrared sensors, cameras, etc.

[0066] The aforementioned inspection and / or measurement data (MD) can be time-series data. In other words, the inspection and / or measurement data (MD) can be arranged in chronological order. Time-series data is a key characteristic, where events are organized for processing according to the order of occurrence and arrival. In other words, the inspection and / or measurement data (MD) can be stored based on the time points in which the inspection and / or measurement were performed, and the inspection and / or measurement data (MD) can be time-related. Furthermore, the inspection and / or measurement data (MD) can be related to the location on the electrodes identified based on reference points.

[0067] The processing unit 1133 can be configured to collect inspection and / or measurement signals MS sensed by the sensing unit 1131 to generate inspection and / or measurement data (MD). The processing unit 1133 can be connected to the sensing unit 1131 via wired or wireless means.

[0068] The roll-up PLC 1171 can communicate operationally with the first rotary encoder 1121 and the second rotary encoder 1125, inspection and / or measuring instruments 1130, and other measuring instruments and inspectors via a wired or wireless data network. The data network can be one-way or two-way. The data network can be implemented using public and / or private networks using physical channels, Wi-Fi, Bluetooth, and / or other frequency bands. The first rotary encoder 1121 and the second rotary encoder 1125, measuring instruments 1130, and additional measuring instruments and inspectors can be configured to collect data from equipment, workpieces, semi-finished products, and finished products within the electrode processing apparatus 110, or to generate signals for collecting data.

[0069] The roll-up PLC 1171 can be configured to transmit coordinate data (CD) to the processing unit 1133. The processing unit 1133 can be configured to associate inspection and / or measurement data (MD) with the coordinate data (CD) to generate coordinate-dependent measurement data (CMD). Typically, the inspection and / or measurement data (MD) can be processed based on trigger points. Examples of processing inspection and / or measurement data (MD) may include storing inspection and / or measurement data (MD), manipulating inspection and / or measurement data (MD) (e.g., generating coordinate-dependent inspection and / or measurement data (CMD)), and transmitting inspection and / or measurement data (MD).

[0070] As a non-limiting example, the trigger point for processing inspection and / or measurement data (MD) can be the completion of a scan. For example, the sensing unit 1131 can scan the electrode in the width direction of the electrode, and for each scan, it can store, process, modulate, and transmit the inspection and / or measurement data (MD). In other examples, the trigger point can be the completion of multiple scans or the completion of a partial scan.

[0071] The processing unit 1133 can be configured to send coordinate-related inspection and / or measurement data (CMD) to the roll pattern PLC 1171. The roll pattern PLC 1171 can be configured to transfer coordinate-related inspection and / or measurement data (CMD) to the process PLC 1143.

[0072] Coordinate-dependent inspection and / or measurement data (CMD) transmitted to the process PLC 1143 can be sent to the first server 150 via the process PLC 1143 and the Equipment Interface (EIF) 145. The process PLC 1143 and EIF 145 can relay data communication, including coordinate-dependent inspection and / or measurement data (CMD), between the first server 150 and the roll drawing PLC 1171. However, this is not a limitation; the first roll drawing PLC 1171 can be configured to transmit coordinate-dependent inspection and / or measurement data (CMD) directly to the first server 150.

[0073] The process PLC 1143 can be configured to control the operation of the unwinder 1111, the rewinder 1113, and the processing machine 1115. The process PLC 1143 can be configured to generate signals for operating and stopping the unwinder 1111, the rewinder 1113, and the processing machine 1115.

[0074] In some implementations, each of the roll plotting PLC 1171 and the process PLC 1143 can be part of a single PLC, namely the first PLC 1140.

[0075] In order to control Figure 3 The electrode process shown can be connected via an EIF 145 by installing a communication line between the process PLC 1143 and the first server 150. Therefore, data transmission through the process PLC 1143 can be performed by the first rotary encoder 1121 and the second rotary encoder 1125, as well as the inspection and / or measuring instrument 1130, which directly transmit the unwinding amount signal (UWAS), winding amount signal (WAS), and inspection and / or measurement signal (MS) to the first server 150. Compared to the case where the roll pattern PLC 1171 directly transmits coordinate-related inspection and / or measurement data (MD) to the first server 150, this reduces the resources required for installing the communication line and allows for more efficient data processing and management.

[0076] EIF 145 can be a device for communication between a process PLC 1143 used in a manufacturing facility and a first server 150 acting as an upper-level server.

[0077] In some embodiments, the first server 150 may include a roll pattern generation unit configured to generate a roll pattern. The roll pattern may be process data of the electrode E1 on a plane simulating the movement of the electrode E1 between the unwinder 1111 and the rewinder 1113. In this case, the first server 150 may serve as a roll pattern generation device.

[0078] In some embodiments, the roll pattern PLC 1171 may include a roll pattern generation unit configured to generate roll patterns. In this case, the roll pattern PLC 1171 may function as a roll pattern generation device. The case where the first server 150 generates the roll pattern will be described below. However, the roll pattern PLC 1171 may also be configured to generate roll patterns in the same, equivalent, or similar manner as the configuration associated with the first server 150 that generates the roll pattern.

[0079] Roll patterns can be generated in batches by winding and cutting electrode E1. Roll patterns can include batch specification data. Batch specifications can include, for example, batch number, length of the wound electrode, winding direction of the electrode roll, unwinding direction of the electrode roll, width of the electrode, and materials and composition used in electrode processing.

[0080] In some implementations... Figure 3 The electrode process shown can be a roll forming process. In this case, the roll pattern can be a roll pattern of the roll forming process.

[0081] In other embodiments, Figure 3 The electrode process shown can be a grooving process. In this case, the roll pattern can be a roll pattern of the grooving process.

[0082] According to an exemplary embodiment, the first server 150 may be a data processing system that supports the management of various activities required for the manufacture of secondary batteries, such as work progress management, work instructions, quality management, and work performance aggregation. The first server 150 may be, for example, a manufacturing execution system (MES). The first server 150 may be configured to perform the input, processing, output, and communication of data required for electrode assembly, such as grooving processes, cutting processes, and stacking processes.

[0083] The first server 150 can generate visualization commands (VCs) for visualizing the roll chart. The first server 150 can transmit the visualization commands (VCs) to the display device 160, and the display device 160 can visualize the roll chart to display the visualized roll chart.

[0084] In some embodiments, the processing unit 1133 may be configured to transmit coordinate-related inspection and / or measurement data (CMD) and / or coordinate data (CD) to the second server 180. According to an exemplary embodiment, the coordinate-related inspection and / or measurement data (CMD) and coordinate data (CD) may be transmitted to the second server 180 via eIoT 170. eIoT 170 may be a means for communication between the processing unit 1133 and the second server 180.

[0085] In some implementations, the second server 180 may be configured to store and process inspection and / or measurement data (MD) of the electrodes. The second server 180 can continuously monitor the processing of the electrodes based on the inspection and / or measurement data (MD), thereby managing the processing quality of the electrodes. According to an exemplary implementation, the second server 180 may be a statistical process controller (SPC). By collecting and analyzing manufacturing data in near real-time, the second server 180 can promptly identify problem conditions and provide alerts to operators before potential problems occur.

[0086] The third server 190 can be configured to store coordinate-related inspection and / or measurement data (CMD) sent from the first server 150. The third server 190 can also be configured to store inspection and / or measurement data (MD) sent from the second server 180. When the first server 150 is an MES and the second server 180 is an SPC, they may not be suitable for long-term storage of coordinate-related inspection and / or measurement data (CMD), evaluation data (ED), and inspection and / or measurement data (MD). For example, the third server 190 can be a data warehouse and can store coordinate-related inspection and / or measurement data (CMD), evaluation data (ED), and inspection and / or measurement data (MD) for extended periods, such as based on the product's warranty period.

[0087] Processing unit 1133, volume diagram PLC 1171, process PLC 1143, EIF 145, first server 150, eIoT 170, second server 180, and third server 190 can be implemented as hardware, firmware, software, or combinations thereof. For example, processing unit 1133, volume diagram PLC 1171, process PLC 1143, EIF 145, first server 150, eIoT 170, second server 180, and third server 190 may include computing devices such as workstation computers, desktop computers, laptops, tablets, etc. Processing unit 1133, volume diagram PLC 1171, process PLC 1143, EIF 145, first server 150, eIoT 170, second server 180, and third server 190 may include any of the following: simple controllers, complex processors such as microprocessors, CPUs, GPUs, software-configurable processors, and dedicated hardware and firmware. The processing unit 1133, the volume diagram PLC 1171, the process PLC 1143, the EIF 145, the first server 150, the eIoT 170, the second server 180, and the third server 190 can be implemented by, for example, a general-purpose computer or special-purpose hardware such as digital signal processing (DSP), field programmable gate array (FPGA), and application-specific integrated circuit (ASIC)).

[0088] First server 150 and second server 180 can generate a roll diagram as a base roll diagram and intermediate roll diagrams generated based on that roll diagram. Because first server 150 stores and processes a large amount of data for general manufacturing management, in addition to the roll diagram, the roll diagram stored on first server 150 can include processed and simplified coordinate-dependent measurement data (CMD), rather than raw inspection and / or measurement data (MD). Second server 180 can store raw inspection and / or measurement data (MD) for SPC operation. Second server 180 can, in response to commands from first server 150, send inspection and / or measurement data (MD) corresponding to selected portions of the roll diagram.

[0089] Intermediate roll plots may also include inspection and / or measurement data (MD) associated with the roll plot; in other words, in addition to the roll plot, intermediate roll plots may include inspection and / or measurement data (MD) as raw data. Inspection and / or measurement data (MD) can be associated with the roll plot based on time values. Therefore, intermediate roll plots can provide additional insights into work product quality, process performance, overall equipment efficiency (OEE), anomaly detection, traceability, preventative maintenance, and predictive alerts.

[0090] The first server 150, the second server 180, and the third server 190 may include physical servers or cloud servers. The first server 150, the second server 180, and the third server 190 can provide data and analysis results to the operator through various frameworks. The frameworks may include protocols that support data transmission, enabling the display device 160 to visualize data through a user interface and providing updated visualizations as the first server 150 and the second server 180 calculate new data. Protocols supporting data transmission may use HTML, JavaScript, and / or JSON.

[0091] The first server 150, the second server 180, and the third server 190 may include various application programming interfaces (APIs) for storing data in databases and other data management tools. The APIs can also be used to retrieve data from the databases of various data management systems. The data management system can provide access to the database, extract data from the database, retrieve data from the database, and generate metrics. In this context, metrics are tools for visualizing data. Metrics include time-series generated measurements that can be used to monitor applications and generate status alerts.

[0092] The electrode process apparatus 110 can be implemented with a plug-in architecture featuring an API for data acquisition, providing plug-and-play connectivity for inspection and / or measuring instruments 1130, as well as additional measuring instruments and inspectors. Therefore, resources at specific process steps and locations can be easily relocated to other processes and locations, or new resources can be easily introduced at each process step and location.

[0093] The data network between components of the electrode process apparatus 110 may include various types of communication channels, including one-way, two-way wired, and wireless communication. In one example, the data network may include industrial protocol networks such as OPC, Modbus, ProfiNet, etc. Communication channels may be dedicated pipe communications, such as Universal Serial Bus (USB), IEEE 802 (Ethernet), IEEE 1394 (FireWire), or other high-speed data communication standards.

[0094] In some embodiments, the electrode processing apparatus 110 may also include a manual input system that allows operators to input manufacturing data. The electrode processing apparatus 110 may allow operators to input data using input tools, as well as computer-based manufacturing data input, such as by capturing an Excel file.

[0095] According to some embodiments, the operation of the processing unit 1133, the volume plotting PLC 1171, the process PLC 1143, the EIF 145, the first server 150, the eIoT 170, the second server 180, and the third server 190 can be implemented as commands stored on a machine-readable medium, which can be read and executed by one or more processors. Here, the machine-readable medium can include any mechanism for storing and / or transmitting information in a machine-readable (e.g., computing device) form. For example, the machine-readable medium can include read-only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory, electrical, optical, acoustic, or other forms of propagation signals (e.g., carrier waves, infrared signals, digital signals, etc.), and any other signals.

[0096] The processing unit 1133, the volume diagram PLC 1171, the process PLC 1143, the EIF 145, the first server 150, the eIoT 170, the second server 180, and the third server 190 may include firmware, software, routines, and commands for performing the operations described above or any of the processes / procedures described below. For example, the processing unit 1133, the volume diagram PLC 1171, the process PLC 1143, the EIF 145, the first server 150, the eIoT 170, the second server 180, and the third server 190 may be instantiated in memory.

[0097] For example, the processing unit 1133 can be implemented by software configured to receive coordinate data (CD), generate coordinate correlation check and / or measurement data (CMD), and transmit the check and / or measurement data (MD), coordinate data (CD), and coordinate correlation check and / or measurement data (CMD).

[0098] For example, the roll diagram PLC 1171 can be implemented by software configured to collect coordinate data (CD), receive coordinate-related inspection and / or measurement data (CMD), and transmit coordinate data (CD) and coordinate-related inspection and / or measurement data (CMD).

[0099] The process PLC 1143 can be implemented by software that is configured to generate control signals for controlling the unwinder 1111, rewinder 1113 and processing machine 1115 based on the product ID and product recipe, receive coordinate data (CD) and coordinate-related inspection and / or measurement data (CMD), and transmit coordinate data (CD) and coordinate-related inspection and / or measurement data (CMD).

[0100] EIF 145 can be implemented via software for relaying data and information transmission between process PLC 1143 and first server 150. More specifically, EIF 145 can be implemented via software configured to perform flow control, error control, synchronization, sequence control, addressing, multiplexing, routing, and formatting for communication between process PLC 1143 and first server 150.

[0101] For example, the first server 150 can be implemented by software configured to transmit product IDs and product recipes to the process PLC 1143 and generate roll plots based on coordinate-dependent inspection and / or measurement data (CMD).

[0102] eIoT 170 may include software configured to collect, store, process, and transmit time-series data, coordinate data (CD), and / or coordinate-related inspection and / or measurement data (CMD), such as inspection and / or measurement data (MD).

[0103] The second server 180 can be implemented by software configured to store time-series data, coordinate data (CD), and / or coordinate-related inspection and / or measurement data (CMD), such as inspection and / or measurement data (MD), monitor the process / operation based on the time-series data, coordinate data (CD), and / or coordinate-related inspection or measurement data, and transmit the time-series data, coordinate data (CD), and / or coordinate-related inspection and / or measurement data (CMD) in response to requests from the first server 150.

[0104] The third server 190 can be implemented by software configured to receive and store inspection and / or coordinate-related measurement data (CMD), evaluation data (ED), and / or inspection and / or measurement data (MD), and to retrieve coordinate-related inspection and / or measurement data (CMD), evaluation data (ED), and / or inspection and / or measurement data (MD).

[0105] However, this is only for ease of description, and the operation of the aforementioned processing unit 1133, volume diagram PLC 1171, process PLC 1143, EIF 145, first server 150, eIoT 170, second server 180 and third server 190 may be caused by other devices such as execution computing devices, distributed computing devices, processors, firmware, software, routines and commands.

[0106] Figure 4 A schematic diagram of a residual electrode roll according to an embodiment of the present disclosure is shown conceptually.

[0107] Reference Figure 4When a defect F is detected on electrode E1, tag T is assigned to the corresponding location. As described above, the defect F on electrode E1 can be detected by inspection and / or measuring instrument 1130 (see [reference]). Figure 3 The device can identify and store the tag coordinates corresponding to the location of the identified defect F on electrode E1.

[0108] The portion of electrode E1 with defect F needs to be removed. When the portion with defect F is removed, the total length of electrode E1 is shortened accordingly.

[0109] Based on the tag coordinates indicating the location of the defect F in electrode E1, a pre-removal standard coordinate C1, placed before the tag coordinates, and a post-removal standard coordinate C2, placed after the tag coordinates, can be defined. Furthermore, the segment between the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 can be defined as the electrode removal segment R.

[0110] The preceding removal standard coordinate C1 can be a coordinate preceding the label coordinates by a predetermined length a. In some embodiments, the following removal standard coordinate C2 can be a coordinate following the label coordinates by a predetermined length a. In some embodiments, the length of the electrode removal segment R can be 2a, which is twice the predetermined length a.

[0111] By eliminating the electrode removal segment R in electrode E1, a roll diagram of the remaining electrode S can be generated. In the physical electrode, the electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 can be cut and discarded, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 can be combined with each other.

[0112] Figure 5 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually.

[0113] Reference Figure 5 The device can detect a first defect F1 located relatively ahead and a second defect F2 located relatively behind along the process direction of electrode E1. The roll pattern generation apparatus can assign a first tag T1 to correspond to the position of the first defect F1 and a second tag T2 to correspond to the position of the second defect F2. Furthermore, the roll pattern generation apparatus can store the tag coordinates corresponding to the identified positions of defects F1 and F2 on electrode E1.

[0114] Based on the tag coordinates of the first tag T1 indicating the location of the first defect F1 occurring in electrode E1, a pre-removal standard coordinate C1 placed before the tag coordinates and a post-removal standard coordinate C2 placed after the tag coordinates can be defined. Furthermore, the segment between the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 can be defined as the first electrode removal segment R1.

[0115] Based on the tag coordinates of the second tag T2 indicating the location of the second defect F2 occurring in electrode E1, a pre-removal standard coordinate C3, placed before the tag coordinates, and a post-removal standard coordinate C4, placed after the tag coordinates, can be defined. Furthermore, the segment between the pre-removal standard coordinate C3 and the post-removal standard coordinate C4 can be defined as the second electrode removal segment R2.

[0116] The pre-removal standard coordinate C1 can be a coordinate of a predetermined length a of the label coordinates preceding the first label T1. In some embodiments, the post-removal standard coordinate C2 can be a coordinate of a predetermined length a of the label coordinates following the first label T1. In some embodiments, the length of the first electrode removal segment R1 can be 2a, which is twice the predetermined length a.

[0117] The pre-removal standard coordinate C3 can be a coordinate of a predetermined length a of the label coordinates placed before the second label T2. In some embodiments, the post-removal standard coordinate C4 can be a coordinate of a predetermined length a of the label coordinates placed after the second label T2. In some embodiments, the length of the second electrode removal segment R2 can be 2a, which is twice the predetermined length a.

[0118] The first electrode removal section R1 and the second electrode removal section R2 may not overlap. The roll pattern generating apparatus can generate a roll pattern of the retained electrode S from the electrode E1, wherein both the first electrode removal section R1 and the second electrode removal section R2 are excluded.

[0119] In the physical electrodes, the electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 can be cut and discarded, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 can be joined together. Furthermore, the electrode between the pre-removal standard coordinate C3 and the post-removal standard coordinate C4 can be cut and discarded, and the ends of the pre-removal standard coordinate C3 and the post-removal standard coordinate C4 can be joined together.

[0120] Figure 6 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually. Figure 6a It shows Figure 6 The concept diagram of the same part of the roll drawing of the implementation method is shown, and the corresponding part of the description is shown for clarity.

[0121] Reference Figure 6 and Figure 6aThe device can detect a first defect F1 located relatively ahead and a second defect F2 located relatively behind along the process direction of electrode E1. The roll pattern generation apparatus can assign a first tag T1 to correspond to the position of the first defect F1 and a second tag T2 to correspond to the position of the second defect F2. Furthermore, the roll pattern generation apparatus can store the tag coordinates corresponding to the identified positions of defects F1 and F2 on electrode E1.

[0122] Based on the tag coordinates of the first tag T1 indicating the location of the first defect F1 occurring in electrode E1, a pre-removal standard coordinate C1 placed before the tag coordinates and a post-removal standard coordinate C2 placed after the tag coordinates can be defined. Furthermore, the segment between the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 can be defined as the first electrode removal segment R1.

[0123] Based on the tag coordinates of the second tag T2, which indicates the location of the second defect F2 in electrode E1, a pre-removal standard coordinate C3, placed before the tag coordinates, and a post-removal standard coordinate C4, placed after the tag coordinates, can be defined. Furthermore, based on the tag coordinates, the segment between the pre-removal standard coordinate C3 and the post-removal standard coordinate C4 can be defined as the second electrode removal segment R2.

[0124] The pre-removal standard coordinate C1 can be a coordinate of a predetermined length a of the label coordinates placed before the first label T1. In some embodiments, the post-removal standard coordinate C2 can be a coordinate of a predetermined length a of the label coordinates placed after the first label T1. In some embodiments, the length of the second electrode removal segment R1 can be 2a, which is twice the predetermined length a.

[0125] The pre-removal standard coordinate C3 can be a coordinate of a predetermined length a of the label coordinates placed before the second label T2. In some embodiments, the post-removal standard coordinate C4 can be a coordinate of a predetermined length a of the label coordinates placed after the second label T2. In some embodiments, the length of the second electrode removal segment R2 can be 2a, which is twice the predetermined length a.

[0126] The first electrode removal section R1 and the second electrode removal section R2 may overlap by a predetermined length in the longitudinal direction of electrode E1. In other words, a portion of the first electrode removal section R1 overlaps with the second electrode removal section R2, and a portion of the second electrode removal section R2 also overlaps with the first electrode removal section R1.

[0127] The merged electrode removal segment RM can be defined as the segment between the preceding removal standard coordinate C1 (i.e., the earliest removal standard coordinate in the first electrode removal segment R1) and the following removal standard coordinate C4 (i.e., the last removal standard coordinate in the second electrode removal segment R2) of the second electrode removal segment R1 and R2. The merged electrode removal segment RM can be removed from the entire electrode E1. The roll image generation device can generate a roll image of the remaining electrode S, in which the merged electrode removal segment RM has been removed from the electrode E1.

[0128] Figure 6a In this context, A represents the first electrode removal segment R1. The first electrode removal segment R1 can be the segment between the pre-removal standard coordinate C1 and the post-removal standard coordinate C2 corresponding to the first label T1.

[0129] Figure 6a In this context, B represents the second electrode removal segment R2. The second electrode removal segment R2 can be the segment between the preceding removal standard coordinate C3 and the following removal standard coordinate C4 corresponding to the second label T2. The second electrode removal segment R2 can have a portion R2i that does not overlap with the first electrode removal segment R1.

[0130] Figure 6a In the diagram, C represents the merged electrode removal segment RM, where the first electrode removal segment R1 and the second electrode removal segment R2 are merged. As shown in C, the merged electrode removal segment RM can be obtained by adding a non-overlapping portion R2i to the first electrode removal segment R1.

[0131] In the physical electrode, the electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C4 of the merged electrode segment RM can be cut and discarded, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C4 can be combined with each other.

[0132] Figure 7 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually. Figure 7 Implementation methods and Figure 6 The difference in the implementation lies in the addition of a third defect F3. Therefore, the description below will focus on these differences, and descriptions of common parts will be omitted.

[0133] Reference Figure 7 A third defect F3 can be detected along the process direction of electrode E1, following the first defect F1 and the second defect F2. However, the third defect F3 may be located within the merged electrode removal section RM derived from the first defect F1 and the second defect F2.

[0134] The roll pattern generating apparatus can assign a third label T3 to correspond to the position of the third defect F3. Furthermore, the roll pattern generating apparatus can store the label coordinates corresponding to the position of the identified third defect F3.

[0135] Based on the tag coordinates of the third tag T3, which indicates the location of the third defect F3 in electrode E1, a pre-removal standard coordinate C5, placed before the tag coordinates, and a post-removal standard coordinate C6, placed after the tag coordinates, can be defined. Furthermore, the segment between the pre-removal standard coordinate C5 and the post-removal standard coordinate C6 can be defined as the third electrode removal segment R3.

[0136] The pre-removal standard coordinate C5 can be a coordinate of a predetermined length a of the label coordinates preceding the third label T3. In some embodiments, the post-removal standard coordinate C6 can be a coordinate of a predetermined length a of the label coordinates following the third label T3. In some embodiments, the length of the third electrode removal segment R3 can be 2a, which is twice the predetermined length a.

[0137] The preceding removal standard coordinate C5 can be placed before the following removal standard coordinate C4 of the second electrode removal segment R2. The following removal standard coordinate C6 can be placed after the following removal standard coordinate C4 of the second electrode removal segment R2.

[0138] The preceding removal standard coordinate C5 can be placed before the last removal standard coordinate C4 of the merged electrode removal segment RM. The following removal standard coordinate C6 can be placed after the last removal standard coordinate C4 of the merged electrode removal segment RM.

[0139] The third electrode removal section R3 may overlap the merging electrode removal section RM by a predetermined length in the longitudinal direction of electrode E1. In other words, a portion of the third electrode removal section R3 overlaps with the merging electrode removal section RM, and a portion of the merging electrode removal section RM overlaps with the third electrode removal section R3.

[0140] By merging the merged electrode removal segment RM and the third electrode removal segment R3, the updated merged electrode removal segment RM' can be defined. Figure 8 A conceptual diagram of a merged electrode removal section, which is combined with a third electrode removal section, according to an embodiment of the present disclosure is shown.

[0141] Reference Figure 8An updated merged electrode removal segment RM' can be obtained by adding a non-overlapping segment R3i (see Figure B) to the merged electrode removal segment RM' (see Figure C). This non-overlapping segment is the segment in the third electrode removal segment R3 that does not overlap with the merged electrode removal segment RM'. In some embodiments, the foremost removal standard coordinate C1 in the merged electrode removal segment RM can be selected as the foremost removal standard coordinate of the updated merged electrode removal segment RM'. Furthermore, the subsequent removal standard coordinate C6 of the third electrode removal segment R3 can be selected as the subsequent removal target coordinate of the updated merged electrode removal segment RM'.

[0142] As a result, the updated merged electrode removal segment RM' can be formed by the segment between the preceding removal standard coordinate C1 of the first electrode removal segment R1 and the following removal standard coordinate C6 of the third electrode removal segment R3. The preceding removal standard coordinate C1 is the foremost removal standard coordinate among the first to third electrode removal segments R1, R2, and R3, and the following removal standard coordinate C6 is the last removal standard coordinate. The merged electrode removal segment RM' can be removed from the entire electrode E1. The roll image generation device can generate a roll image of the remaining electrode S, in which the merged electrode removal segment RM' has been removed from the electrode E1.

[0143] The electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C6 of the combined electrode removal section RM' can be cut and discarded from the physical electrode, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C6 can be combined with each other.

[0144] Figure 9 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually. Figure 9 Implementation methods and Figure 7 The implementation differs in that a fourth defect F4 is added after the merging electrode removal section RM. Therefore, the following description will focus on these differences, omitting descriptions of common parts.

[0145] Reference Figure 9 The fourth defect F4, following the merged electrode removal section RM, can be detected along the process direction of electrode E1. The roll pattern generation apparatus can assign a fourth tag T4 to correspond to the location of the fourth defect F4. Furthermore, the roll pattern generation apparatus can store the tag coordinates corresponding to the location of the identified fourth defect F4.

[0146] Based on the tag coordinates of the fourth tag T4, which indicates the location of the fourth defect F4 in electrode E1, a pre-removal standard coordinate C7, placed before the tag coordinates, and a post-removal standard coordinate C8, placed after the tag coordinates, can be defined. Furthermore, the segment between the pre-removal standard coordinate C7 and the post-removal standard coordinate C8 can be defined as the fourth electrode removal segment R4.

[0147] The pre-removal standard coordinate C7 can be a coordinate of a predetermined length 'a' of the label coordinates preceding the fourth label T4. In some embodiments, the post-removal standard coordinate C8 can be a coordinate of a predetermined length 'a' of the label coordinates following the fourth label T4. In some embodiments, the length of the fourth electrode removal segment R4 can be 2a, which is twice the predetermined length 'a'.

[0148] The preceding removal standard coordinate C7 can be placed before the following removal standard coordinate C4 of the second electrode removal segment R2. The following removal standard coordinate C8 can be placed after the following removal standard coordinate C4 of the second electrode removal segment R2.

[0149] The preceding removal standard coordinate C7 can be placed before the last removal standard coordinate C4 of the merged electrode removal segment RM. The following removal standard coordinate C8 can be placed after the last removal standard coordinate C4 of the merged electrode removal segment RM.

[0150] The fourth electrode removal segment R4 may overlap the merging electrode removal segment RM by a predetermined length in the longitudinal direction of electrode 1. In other words, a portion of the fourth electrode removal segment R4 overlaps with the merging electrode removal segment RM, and a portion of the merging electrode removal segment RM overlaps with the fourth electrode removal segment R4.

[0151] The updated merged electrode removal segment RM' can be defined by merging the merged electrode removal segment RM and the fourth electrode removal segment R4. The merging of the merged electrode removal segment RM and the fourth electrode removal segment R4 can be compared with a reference... Figure 8 The same method described above shall be used.

[0152] In this case, the segment between the preceding removal standard coordinate C1 of the first electrode removal segment R1 (i.e., the foremost removal standard coordinate among the first, second, and fourth electrode removal segments R1, R2, and R4) and the following removal standard coordinate C8 of the fourth electrode removal segment R4 (i.e., the last removal standard coordinate) can form an updated merged electrode removal segment RM'. The merged electrode removal segment RM' can be removed from the entire electrode E1. The roll pattern generation device can generate a roll pattern of the remaining electrode S, in which the merged electrode removal segment RM' has been removed from the electrode E1.

[0153] The electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C8 of the combined electrode removal section RM' can be cut and discarded from the physical electrode, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C8 can be combined with each other.

[0154] (Second Implementation)

[0155] Figure 10 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually. Figure 10 The illustrated implementation and Figure 4 The difference in the illustrated implementation is that the properties of the defect are continuous. In other words, Figure 4 In the illustrated embodiment, defect F is a point defect, where the location can be specified by any coordinate. On the other hand, Figure 10 The defect F in the illustrated embodiment is a continuous defect that is difficult to specify by any coordinate because the defect extends in the longitudinal direction of electrode E1.

[0156] Reference Figure 10 When a continuous defect F is detected on electrode E1, two or more tags T1, T2, ..., Tn can be assigned. In other words, two or more tags T1, T2, ..., Tn can be assigned at a predetermined interval g, while the continuous defect F on electrode E1 continues in the longitudinal direction of electrode E1.

[0157] Defect F on electrode E1 can be inspected and / or measured by instrument 1130 (see...) Figure 3 The image generation apparatus can first identify the location of defect F on electrode E1, assign a first tag T1, assign a second tag T2 at predetermined intervals g, and assign an nth tag Tn at the end of defect F. Furthermore, the image generation apparatus can store the tag coordinates corresponding to each of the tags T1, T2, ..., Tn.

[0158] Based on the first label T1, the pre-removal standard coordinate C1 can be defined. In some embodiments, the post-removal standard coordinate can be defined based on the first label T1. Furthermore, the segment between the pre-removal standard coordinate C1 and the post-removal standard coordinate can be defined as the electrode removal segment R1 of the first label T1.

[0159] The preceding removal standard coordinate C1 can be a coordinate preceding the label coordinate by a predetermined length a. In some embodiments, the following removal standard coordinate can be a coordinate following the label coordinate by a predetermined length a. In some embodiments, the length of the electrode removal segment R can be 2a, which is twice the predetermined length a.

[0160] In some implementations, the electrode removal sections for the second tag T2 to the nth tag Tn can be defined in the same manner as for the first tag T1.

[0161] Specifically, the post-removal standard coordinates C2n can be defined based on the nth label Tn. In some implementations, the pre-removal standard coordinates can be defined based on the nth label Tn. Furthermore, the segment between the pre-removal standard coordinates and the post-removal standard coordinates C2n can be defined as the electrode removal segment Rn of the nth label Tn.

[0162] The roll pattern generation apparatus can be configured to merge each electrode removal segment to produce a merged electrode removal segment RM, as referenced. Figure 6a and Figure 8 As stated above.

[0163] The interval g between two or more tags T1, T2, ..., Tn can be less than or equal to 2a, which is the length of the electrode removal segment for a tag.

[0164] In some implementations, when the defect F is a continuous defect, the roll pattern generating apparatus can be configured to define the segment between the preceding removal standard coordinate C1 corresponding to the foremost assignment label (i.e., the first label T1) and the following removal standard coordinate C2n corresponding to the last assignment label (i.e., the nth label Tn) as the merged electrode removal segment RM.

[0165] The pre-removal standard coordinate C1 can be a coordinate of a predetermined length a of the label coordinates preceding the first label T1. The post-removal standard coordinate C2n can be a coordinate of a predetermined length a of the label coordinates following the nth label Tn. In some embodiments, the length of the merged electrode removal segment RM can be equal to the distance between the first label T1 and the nth label Tn plus a length of 2a.

[0166] The merged electrode removal section RM can be removed from electrode E1 as a whole to remove defect F. The roll pattern generation device can generate a roll pattern of the remaining electrode S, in which the merged electrode removal section RM has been removed from electrode E1.

[0167] The electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C2n in the combined electrode removal section RM of the physical electrode can be cut and discarded, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C2n can be combined with each other.

[0168] (Third implementation method)

[0169] Figure 11 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually.

[0170] Reference Figure 11 A first defect F1, which is a continuous defect, and a second defect F2 and a third defect F3, which are point defects, can be detected on electrode E1. The second defect F2 overlaps with the first defect F1 in the longitudinal direction of electrode E1, while the third defect F3 does not overlap with the first defect F1 in the longitudinal direction of electrode E1.

[0171] For reference Figure 10 Specifically, two or more labels T11, T12, ..., T18 can be assigned at a predetermined interval g in the first defect F1, which is a continuous defect.

[0172] The first defect F1 on electrode E1 can be inspected and / or measured by instrument 1130 (see...). Figure 3 The image generation apparatus identifies and assigns a first tag T11 to the location on electrode E1 where the first defect F1 is first identified, assigns a second tag T12 at predetermined intervals g, and assigns an eighth tag T18 to the location where the defect F1 ends. Furthermore, the image generation apparatus can store the tag coordinates corresponding to each of the tags T11, T12, ..., T18. Those skilled in the art will understand that more or fewer tags can be assigned depending on the extent of the first defect F1's extension in the longitudinal direction of electrode E1 and the size of the tag assignment interval g.

[0173] like Figure 11 As shown in A, the preceding removal standard coordinate C1 can be defined based on the first label T11, which is the foremost label among the labels assigned to the first defect F1. In some embodiments, the subsequent removal standard coordinate can be defined based on the first label T11. The preceding removal standard coordinate C1 can be a coordinate of a predetermined length a of the label coordinate preceding the first label T11.

[0174] The post-removal standard coordinate C16 can be defined based on the eighth label T18, which is the last label among the labels assigned to the first defect F1. The post-removal standard coordinate C16 can be the coordinate of the label coordinates placed after the eighth label T18 with a predetermined length 'a'.

[0175] For reference Figure 6a and Figure 8 The roll pattern generating apparatus can be configured to merge the electrode removal segments assigned to each tag of the first defect F1 to produce a merged electrode removal segment RM. This references... Figure 10 A detailed description has been provided, so additional descriptions are omitted here.

[0176] In some embodiments, the roll pattern generating apparatus may be configured to define the segment between the preceding removal standard coordinate C1 corresponding to the foremost label (i.e., the first label T11) assigned to the first defect F1 that occurred and the following removal standard coordinate C16 corresponding to the last label (i.e., the eighth label T18) assigned to the first defect F1 that occurred as a merged electrode removal segment RM.

[0177] like Figure 11 As shown in B, the roll pattern generating device can assign the corresponding ninth label T2 and the corresponding tenth label T3 to each of the second defect F2 and the third defect F3, which are point defects, and store the corresponding label coordinates.

[0178] The ninth label T2 corresponding to the second defect F2 overlaps with the first defect F1, which is itself a continuous defect. In some embodiments, the roll pattern generating apparatus can be configured not to separately calculate the electrode removal segments of continuous defects and overlapping defects (e.g., the second defect F2).

[0179] In some other embodiments, the roll pattern generating apparatus may define a pre-removal standard coordinate C21 and a post-removal standard coordinate C22 corresponding to the label coordinates of the second defect F2. Furthermore, the segment between the pre-removal standard coordinate C21 and the post-removal standard coordinate C22 may be defined as the second electrode removal segment R2.

[0180] The preceding removal standard coordinate C21 can be a coordinate preceding the label coordinates by a predetermined length a. In some embodiments, the following removal standard coordinate C22 can be a coordinate following the label coordinates by a predetermined length a. In some embodiments, the length of the second electrode removal segment R2 can be 2a, which is twice the predetermined length a.

[0181] In some implementations, the second electrode removal segment R2 may completely overlap with the merged electrode removal segment RM in the longitudinal direction of electrode E1, and therefore may have no effect on determining the length of the electrode being removed.

[0182] The tenth tag T3 corresponding to the third defect F3 does not overlap with the first defect F1, which is itself a continuous defect, but belongs to the merged electrode removal segment RM defined with respect to the first defect F1. In addition to the first defect F1, the roll pattern generating device can also be configured to calculate the electrode removal segment for each of one or more other defects identified as belonging to the merged electrode removal segment RM.

[0183] In some embodiments, the roll pattern generating apparatus may define a pre-removal standard coordinate C31 and a post-removal standard coordinate C32 for the label coordinates of the tenth label T3 corresponding to the third defect F3. Furthermore, the segment between the pre-removal standard coordinate C31 and the post-removal standard coordinate C32 may be defined as the third electrode removal segment R3.

[0184] The pre-removal standard coordinate C31 can be a coordinate of a predetermined length a of the label coordinates preceding the tenth label T3. In some embodiments, the post-removal standard coordinate C32 can be a coordinate of a predetermined length a of the label coordinates following the tenth label T3. In some embodiments, the length of the second electrode removal segment R3 can be 2a, which is twice the predetermined length a.

[0185] The pre-removal standard coordinate C31 may be placed before the final removal standard coordinate C16 of the combined electrode removal section RM of the first defect F1. The post-removal standard coordinate C32 may be placed after the final removal standard coordinate C16 of the combined electrode removal section RM of the first defect F1.

[0186] The third electrode removal section R3 may overlap the merging electrode removal section RM by a predetermined length in the longitudinal direction of electrode E1. In other words, a portion of the third electrode removal section R3 overlaps with the merging electrode removal section RM, and a portion of the merging electrode removal section RM overlaps with the third electrode removal section R3.

[0187] like Figure 11 As shown in C, by merging the merged electrode removal section RM with the third electrode removal section R3, the updated merged electrode removal section RM' can be defined.

[0188] By adding the non-overlapping segment R3i to the merged electrode removal segment RM, an updated merged electrode removal segment RM' can be obtained. This non-overlapping segment is the segment in the third electrode removal segment R3 that does not overlap with the merged electrode removal segment RM'. In some embodiments, the foremost removal standard coordinate C1 in the merged electrode removal segment RM can be selected as the foremost removal standard coordinate of the updated merged electrode removal segment RM'. Alternatively, the subsequent removal standard coordinate C32 of the third electrode removal segment R3 can be selected as the subsequent removal target coordinate of the updated merged electrode removal segment RM'.

[0189] As a result, the segment between the preceding removal standard coordinate C1 of the merged electrode removal segment RM and the third electrode removal segment R3, i.e., the preceding removal standard coordinate in the merged electrode removal region RM and the following removal standard coordinate C32 of the third electrode removal segment R3 (i.e., the last removal standard coordinate in the third electrode removal segment R3), can form an updated merged electrode removal segment RM'. The merged electrode removal segment RM' can be removed from the entire electrode E1. The roll image generation device can generate a roll image of the remaining electrode S, in which the merged electrode removal segment RM' has been removed from the electrode E1.

[0190] The electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C32 of the merged electrode removal section RM' from the physical electrode can be cut and discarded, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C32 can be combined with each other.

[0191] (Fourth Implementation)

[0192] Figure 12 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually.

[0193] Reference Figure 12 A first defect F1, which is a continuous defect, and a fourth defect F4, which is a point defect, can be detected on electrode E1. The fourth defect F4 does not overlap with the first defect F1 in the longitudinal direction of electrode E1, nor does it overlap with the merged electrode removal segment RM corresponding to the first defect F1. However, as will be described below, the electrode removal segment corresponding to the fourth defect F4 may partially overlap with the merged electrode removal segment RM corresponding to the first defect F1.

[0194] For reference Figure 10 Specifically, two or more labels T11, T12, ..., T18 can be assigned at a predetermined interval g in the first defect F1, which is a continuous defect.

[0195] The first defect F1 on electrode E1 can be inspected and / or measured by instrument 1130 (see...). Figure 3 The image generation apparatus identifies the first defect F1 on electrode E1 by assigning a first tag T11 at the location where the first defect F1 is first identified, assigning a second tag T12 at predetermined intervals g, and assigning an eighth tag T18 at the location where the defect F1 ends. Furthermore, the image generation apparatus can store the tag coordinates corresponding to each of the tags T11, T12, ..., T18. Those skilled in the art will understand that more or fewer tags can be assigned depending on the extent to which the first defect F1 extends in the longitudinal direction of electrode E1 and the size of the interval g used for tag assignment.

[0196] like Figure 12 As shown in A, the preceding removal standard coordinate C1 can be defined based on the first label T11, which is the foremost label among the labels assigned to the first defect F1. In some embodiments, the subsequent removal standard coordinates can be defined based on the first label T11. The preceding removal standard coordinate C1 can be a coordinate of a predetermined length a of the label coordinates preceding the first label T11.

[0197] The post-removal standard coordinate C16 can be defined based on the eighth label T18, which is the last label among the labels assigned to the first defect F1. The post-removal standard coordinate C16 can be the coordinate of a predetermined length 'a' of the label coordinates placed after the eighth label T18.

[0198] For reference Figure 6a and Figure 8 The roll pattern generating apparatus can be configured to merge electrode removal segments assigned to each tag of the first defect F to produce a merged electrode removal segment RM. This will refer to Figure 10 To avoid providing a detailed description, this article omits additional descriptions.

[0199] In some embodiments, the roll pattern generating apparatus may be configured to define the segment between the preceding removal standard coordinate C1 corresponding to the foremost label (i.e., the first label T11) assigned to the first defect F1 that occurred and the following removal standard coordinate C16 corresponding to the last label (i.e., the eighth label T18) as a merged electrode removal segment RM.

[0200] like Figure 12 As shown in B, the roll pattern generating device can assign the corresponding eleventh label T4 to the fourth defect F4, which is a point defect, and store the corresponding label coordinates.

[0201] The eleventh label T4 corresponding to the fourth defect F4 does not overlap with the first defect F1, which is itself a continuous defect. Furthermore, the eleventh label T4 corresponding to the first defect F1 does not belong to the merged electrode removal section RM defined with respect to the first defect F1. However, the electrode removal section corresponding to the eleventh label T4 (the fourth electrode removal section R4 described below) partially overlaps with the merged electrode removal section RM defined with respect to the first defect F1. The roll pattern generating apparatus is configured to generate a newer merged electrode removal section RM' by merging the electrode removal sections of other defects with the merged electrode removal section RM of the first defect F1 when other defects besides the first defect F1 partially overlap with the merged electrode removal section RM of the first defect F1.

[0202] In some embodiments, the roll pattern generating apparatus may define a pre-removal standard coordinate C41 and a post-removal standard coordinate C44 for the tag coordinates of the eleventh tag T4 corresponding to the fourth defect F4. Furthermore, the segment between the pre-removal standard coordinate C41 and the post-removal standard coordinate C44 may be defined as the fourth electrode removal segment R4.

[0203] The pre-removal standard coordinate C41 can be a coordinate of a predetermined length a of the label coordinates preceding the eleventh label T4. In some embodiments, the post-removal standard coordinate C42 can be a coordinate of a predetermined length a of the label coordinates following the eleventh label T4. In some embodiments, the length of the fourth electrode removal segment R4 can be 2a, which is twice the predetermined length a.

[0204] The pre-removal standard coordinate C41 can be placed before the final removal standard coordinate C16 of the combined electrode removal section RM of the first defect F1. The post-removal standard coordinate C42 can be placed after the final removal standard coordinate C16 of the combined electrode removal section RM of the first defect F1.

[0205] The fourth electrode removal segment R4 may overlap the merging electrode removal segment RM by a predetermined length in the longitudinal direction of electrode E1. In other words, a portion of the fourth electrode removal segment R4 overlaps with the merging electrode removal segment RM, and a portion of the merging electrode removal segment RM overlaps with the fourth electrode removal segment R4.

[0206] like Figure 12 As shown in C, by merging the above-mentioned merged electrode removal section RM and the fourth electrode removal section R4, the updated merged electrode removal section RM' can be defined.

[0207] The updated merged electrode removal segment RM' can be obtained by adding a non-overlapping segment R4i to the merged electrode removal segment RM, where R4i is a segment in the fourth electrode removal segment R4 that does not overlap with the merged electrode removal segment RM. In some embodiments, the foremost removal standard coordinate C1 in the merged electrode removal segment RM can be selected as the foremost removal standard coordinate of the updated merged electrode removal segment RM'. Alternatively, the subsequent removal standard coordinate C42 of the fourth electrode removal segment R4 can be selected as the subsequent removal target coordinate of the updated merged electrode removal segment RM'.

[0208] As a result, the updated merged electrode removal segment RM' can be formed by the segment between the preceding removal standard coordinate C1 of the merged electrode removal segment RM and the fourth electrode removal segment R4. The preceding removal standard coordinate C1 is the first removal standard coordinate in the merged electrode removal segment RM, and the following removal standard coordinate C42 of the fourth electrode removal segment R4 is the last removal standard coordinate. The merged electrode removal segment RM' can be removed from electrode E1 as a whole. The roll pattern generation device can generate a roll pattern of the remaining electrode S, wherein the merged electrode removal segment RM' is removed from electrode E1.

[0209] The electrode between the foremost removal standard coordinate C1 and the last removal standard coordinate C42 in the combined electrode removal section RM' of the physical electrode can be cut and discarded, and the ends of the foremost removal standard coordinate C1 and the last removal standard coordinate C42 can be combined with each other.

[0210] (Fifth Implementation)

[0211] Figure 13 A schematic diagram of a residual electrode roll according to another embodiment of the present disclosure is shown conceptually.

[0212] Reference Figure 13 The system can detect consecutive defects on electrode E1, namely the first defect F1 and the fifth defect F5. The fifth defect F5 does not overlap with the first defect F1 in the longitudinal direction of electrode E1, nor does it overlap with the first merged electrode removal segment RM1 corresponding to the first defect F1. However, as will be described below, the electrode removal segment corresponding to the fifth defect F5 (i.e., the second merged electrode removal segment RM2) may partially overlap with the first merged electrode removal segment RM1 corresponding to the first defect F1.

[0213] In the first defect F1, two or more labels T11, T12, ..., T15 can be assigned at predetermined intervals g. Furthermore, in the fifth defect F5, two or more labels T21, T22, ..., T24 can be given at predetermined intervals.

[0214] like Figure 13 As shown in A, the first defect F1 on electrode E1 can be inspected and / or measured by instrument 1130 (see Figure 1130). Figure 3The image generation apparatus identifies the first defect F1 on electrode E1 and assigns a first label T11 at the location where the first defect F1 is first identified, assigns a second label T12 at predetermined intervals g, and assigns a fifth label T15 at the location where the defect F1 ends. Furthermore, the image generation apparatus can store the label coordinates corresponding to each of the labels T11, T12, ..., T15. Those skilled in the art will understand that more or fewer labels can be assigned depending on the extent of the first defect F1's extension in the longitudinal direction of electrode E1 and the size of the interval g used for label assignment.

[0215] like Figure 13 As shown in B, the fifth defect F5 on electrode E1 can be detected by inspection and / or measurement instrument 1130 (see Figure B). Figure 3 The image generation apparatus identifies and assigns a first label T21 at the location where the first defect F1 is first identified on electrode E1, assigns a second label T22 at predetermined intervals, and assigns a third label T24 at the location where defect F1 ends. Furthermore, the image generation apparatus can store the label coordinates corresponding to each of the labels T21, T22, ..., T24. Those skilled in the art will understand that more or fewer labels can be assigned depending on the extent of the fifth defect F5's extension in the longitudinal direction of electrode E1 and the size of the interval used for label assignment.

[0216] The preceding removal standard coordinate C1 can be defined based on the first label T11, which is the foremost label assigned to the first defect F1. In some embodiments, the following removal standard coordinates can be defined based on the first label T11. The preceding removal standard coordinate C1 can be a coordinate of a predetermined length 'a' of the label coordinates preceding the first label T11.

[0217] The post-removal standard coordinate C10 can be defined based on the fifth label T15, which is the last label assigned to the first defect F1. The post-removal standard coordinate C10 can be the coordinate of the label coordinates placed after the fifth label T15 by a predetermined length 'a'.

[0218] For reference Figure 6a and Figure 8 The roll pattern generating apparatus can be configured to merge electrode removal segments assigned to each tag of the first defect F1 to produce a first merged electrode removal segment RM1. This has been referenced. Figure 10 A detailed description is required, so additional descriptions are omitted here.

[0219] In some embodiments, the roll pattern generating apparatus may be configured to define a first merged electrode removal segment RM1 between a preceding removal standard coordinate C1 corresponding to the foremost label (i.e., the first label T11) assigned to the first defect F1 that occurred and a following removal standard coordinate C10 corresponding to the last label (i.e., the fifth label T15) assigned to the first defect F1 that occurred.

[0220] The 21st to 24th labels T24, corresponding to the fifth defect F5, do not overlap with the first defect F1, which is itself a continuous defect. Furthermore, the 21st to 24th labels T24 do not belong to the first merged electrode removal section RM1 defined in relation to the first defect F1. However, the electrode removal section corresponding to the fifth defect F5 (i.e., the second merged electrode removal section RM2) and the first merged electrode removal section RM1 defined in relation to the first defect F1 partially overlap. When the merged electrode removal section of a defect other than the first defect F1 partially overlaps with the first merged electrode removal section RM1 of the first defect F1, the roll pattern generating apparatus is configured to merge the merged electrode removal section of the other defect with the first merged electrode removal section RM1 to generate a newer merged electrode removal section RM'.

[0221] The preceding removal standard coordinate C51 can be defined based on the twenty-first label T21, which is the foremost label among the labels assigned to the fifth defect F5. In some embodiments, the following removal standard coordinates can be defined based on the twenty-first label T21. The preceding removal standard coordinate C51 can be a coordinate of a predetermined length 'a' of the label coordinates preceding the twenty-first label T21.

[0222] The post-removal standard coordinate C58 can be defined based on the twenty-fourth label T24, which is the last label assigned to the fifth defect F5. The post-removal standard coordinate C58 can be the coordinate of a predetermined length 'a' of the label coordinates placed after the twenty-fourth label T24.

[0223] For reference Figure 6a and Figure 8 The roll pattern generating apparatus can be configured to merge the electrode removal segments assigned to each tag of the fifth defect F5 to produce a second merged electrode removal segment RM2. This is consistent with reference to... Figure 10 The detailed descriptions are essentially the same, so additional descriptions are omitted here.

[0224] In some embodiments, the roll pattern generating apparatus may be configured to define the segment between the foremost assignment label (i.e., the foremost removal standard coordinate C51 corresponding to the twenty-first label T21) and the last assignment label (i.e., the last removal standard coordinate C58 corresponding to the twenty-fourth label T24) of the fifth defect F5 as the second merged electrode removal segment RM2.

[0225] The pre-removal standard coordinate C51 can be the coordinate of the tag coordinate of the 21st tag T21 with a predetermined length a. The post-removal standard coordinate C58 can be the coordinate of the tag coordinate of the 24th tag T24 with a predetermined length a. In some embodiments, the length of the second combined electrode removal section RM2 can be the distance between the 21st tag T21 and the 24th tag T24 plus a length of 2a.

[0226] The pre-removal standard coordinate C51 can be placed before the last removal standard coordinate C10 of the first combined electrode removal section RM1 of the first defect F1. The post-removal standard coordinate C58 can be placed after the last removal standard coordinate C10 of the first combined electrode removal section RM1 of the first defect F1.

[0227] The second combined electrode removal section RM2 may overlap with the first combined electrode removal section RM1 and the electrode E1 by a predetermined length in the longitudinal direction of the electrode E1. In other words, a portion of the second combined electrode removal section RM2 overlaps with the first combined electrode removal section RM1, and a portion of the first combined electrode removal section RM1 overlaps with the second combined electrode removal section RM2.

[0228] like Figure 13 As shown in C, by merging the first merged electrode removal segment RM1 and the second merged electrode removal segment RM2, the updated merged electrode removal segment RM' can be defined.

[0229] In the second merged electrode removal segment RM2, an updated merged electrode removal segment RM' can be obtained by adding a non-overlapping segment R5i to the first merged electrode removal segment RM. This non-overlapping segment R5i is a segment that does not overlap with the first merged electrode removal segment RM1. In some embodiments, the leading removal standard coordinate C1 of the first merged electrode removal segment RM1 can be selected as the leading removal standard coordinate of the updated merged electrode removal segment RM'. Alternatively, the trailing removal standard coordinate C58 of the second merged electrode removal segment RM2 can be selected as the trailing removal standard coordinate of the updated merged electrode removal segment RM'.

[0230] As a result, the segment between the preceding removal standard coordinate C1 (the foremost removal standard coordinate of the first combined electrode removal segment RM1) and the following removal standard coordinate C58 (the last removal standard coordinate of the second combined electrode removal segment RM2) of the second combined electrode removal segment RM1 can include the updated combined electrode removal segment RM'. The updated combined electrode removal segment RM' can be removed from the entire electrode E1. The roll pattern generation device can generate a roll pattern of the remaining electrode S, wherein the combined electrode removal segment RM' is removed from the electrode E1.

[0231] The electrode between the pre-removal standard coordinate C1 and the post-removal standard coordinate C58 of the combined electrode removal section RM' in the physical electrode can be cut and discarded, and the ends of the pre-removal standard coordinate C1 and the post-removal standard coordinate C58 can be combined with each other.

[0232] As described above, although embodiments of the present disclosure have been described in detail, those skilled in the art will be able to implement the present disclosure with various modifications without departing from the spirit and scope of the present disclosure as defined in the appended claims. Therefore, further modifications to embodiments of the present disclosure will not depart from the technology of the present disclosure.
