Description

Technical Field

[0001] This disclosure relates to a monitoring data generation system, a monitoring data generation method, and an electrode.

[0002] This application claims priority to Korean Patent Application No. 10-2024-0162961, filed on November 15, 2024, the entire contents of which are incorporated herein by reference. Background Technology

[0003] Batteries are manufactured through electrode processes, assembly processes, and activation processes. Among these processes, the electrode process is the key process that determines the yield and performance of the battery cell. The electrode process can include coating, rolling, and slitting processes. In the coating process, active and insulating materials are applied to the surface of the current collector (electrode sheet). In the rolling process, pressure is applied to the electrode sheet using pressure rollers. In the rolling process, the electrode density, performance, and surface quality can be determined. In the slitting process, the electrode sheet is cut into multiple electrodes according to the design of the battery cell.

[0004] At least one sub-processing (step) can be performed on the electrode sheet that moves during the electrode process. An inspector or measuring device can be provided to check and measure the electrode processing results. The amount of inspection or measurement data obtained by the inspector or measuring device is not large. Therefore, for example, the processor of the inspector or measuring device can directly correlate this data with the coordinates at which it was obtained and send it to a higher-level system.

[0005] On the other hand, multiple device units can be arranged near the electrode sheet that moves to perform sub-processing. Each device unit may include at least one sensor.

[0006] However, the amount of device data obtained from sensors in multiple device units is very large, making it difficult for sensors to correlate device data with coordinate data.

[0007] In addition, since there are many device units, and each device unit contains more sensors than the number of device units, setting up a processor for each sensor to correlate device data with coordinates may significantly increase production costs.

[0008] Therefore, the device data is not associated with coordinates, but only with the time data when each device data is obtained.

[0009] As mentioned above, the equipment data obtained from each equipment unit is not associated with coordinate data, making it difficult to analyze the impact of equipment data on each process.

[0011] Korean Patent Publication No. 2024-0067183 (May 16, 2024) Summary of the Invention

[0012] Technical issues

[0013] This disclosure aims to provide a system and method for generating monitoring data by matching device data with coordinate data, based on time data and device unit identifiers (IDs).

[0014] Technical solution

[0015] To address the aforementioned problems, embodiments of this disclosure provide a monitoring data generation system.

[0016] The monitoring data generation system includes: Multiple device units, each device unit including at least one sensor configured to sense device data and mounted along an electrode sheet; A controller configured to collect coordinate data indicating the position on the electrode sheet when the at least one sensor senses device data; A unit identifier (ID) allocation server, configured to collect the coordinate data and the device data sensed by the at least one sensor at time intervals, assign the unit ID of the device unit to which the at least one sensor belongs to the device data and the time data when the device data is collected, and assign the unit ID of the device unit to which the at least one sensor belongs to the coordinate data and the time data when the coordinate data is collected; and A monitoring data generation server is configured to generate monitoring data by matching the device data with the coordinate data based on the collected time data and the unit ID.

[0017] The coordinate data can be collected based on the unwinding amount signal or the winding amount signal of the electrode sheet.

[0018] The coordinate data when the at least one sensor senses the device data. This can be obtained by adding or subtracting the first offset length from the unwinding or winding amount of the electrode sheet when sensing the device data, and The first offset length may be the length of the electrode sheet between the unwinding machine or winding machine on which the electrode sheet is mounted and the portion of the electrode sheet where the at least one sensor is located.

[0019] The unit ID allocation server can allocate the unit ID to the device data and the collected time data based on reference information, wherein the reference information includes the correspondence between the unit ID of each of the plurality of device units and the at least one sensor belonging to each of the plurality of device units.

[0020] Based on the coordinate data, the monitoring data generation server can generate monitoring data by mapping at least one of the following: at least one unit ID corresponding to the same coordinate data, device data of at least one sensor belonging to each of the at least one unit ID, and at least one piece of collected time data.

[0021] The monitoring data generation system can generate the monitoring data during the electrode manufacturing process, in which the top and bottom surfaces of the electrode sheet are processed sequentially on a continuous process line.

[0022] The monitoring data generation server can match the first device data sensed by at least one first sensor at a position corresponding to the same coordinate data of the electrode plate on the top surface of the electrode plate, and the first unit ID of the first device unit to which the at least one first sensor belongs, with the coordinate data, and

[0023] The second device data sensed by at least one second sensor at a position corresponding to the same coordinate data on the bottom surface of the electrode sheet, and the second unit ID of the second device unit to which the at least one second sensor belongs, can be matched with the coordinate data.

[0024] Another aspect of this disclosure provides a method for generating monitoring data.

[0025] The monitoring data generation method includes: Collect device data sensed by at least one sensor of each of a plurality of electrode device units mounted along the electrode sheet; Coordinate data is collected when the at least one sensor senses device data, the coordinate data indicating the position on the electrode sheet; Assigning the unit identifier (ID) of the device unit to which each of the at least one sensor belongs to the device data and the time data when collecting the device data, and assigning the unit ID of the device unit to which each of the at least one sensor belongs to the coordinate data and the time data when collecting the coordinate data; and Monitoring data is generated by matching the device data with the coordinate data based on the collected time data and the unit ID.

[0026] In the method, the coordinate data can be collected based on the unwinding amount signal or the winding amount signal of the electrode sheet.

[0027] In the method, the coordinate data of the at least one sensor when sensing the device data, This can be obtained by adding or subtracting the first offset length from the unwinding or winding amount of the electrode sheet when sensing the device data, and The first offset length may be the length of the electrode sheet between the unwinding machine or winding machine on which the electrode sheet is mounted and the portion of the electrode sheet where the at least one sensor is located.

[0028] In the method, based on the coordinate data, the monitoring data can be generated by mapping at least one of the following: at least one unit ID corresponding to the same coordinate data, device data of at least one sensor belonging to each of the at least one unit ID, and at least one piece of collected time data.

[0029] In the method, the monitoring data can be generated during the electrode manufacturing process, in which the top and bottom surfaces of the electrode sheet are processed sequentially on a continuous process line.

[0030] In the method, first device data sensed by at least one first sensor at a position corresponding to the same coordinate data of the electrode sheet on the top surface of the electrode sheet, and the first unit ID of the first device unit to which the at least one first sensor belongs, can be matched with the coordinate data.

[0031] The second device data sensed by at least one second sensor at a position corresponding to the same coordinate data on the bottom surface of the electrode sheet, and the second unit ID of the second device unit to which the at least one second sensor belongs, can be matched with the coordinate data.

[0032] Another aspect of this disclosure provides an electrode manufactured by cutting an electrode sheet that moves during the process according to a standard.

[0033] The electrode may include an electrode ID.

[0034] The electrode ID can be: The coordinate data of the position on the electrode sheet during the indicating process, Device data sensed by at least one sensor at the position on the electrode plate indicated by the coordinate data, and The unit ID of the device unit to which the at least one sensor belongs is matched.

[0035] The electrode can be a double-sided coated electrode with electrode paste coated on both the top and bottom surfaces.

[0036] The electrode ID can be matched with the following data: first device data sensed by at least one first sensor at a position corresponding to the coordinate data on the top surface of the electrode sheet, and the first unit ID of the first device unit to which the at least one first sensor belongs; and

[0037] The second device data sensed by at least one second sensor at a position corresponding to the coordinate data on the bottom surface of the electrode sheet, and the second unit ID of the second device unit to which the at least one second sensor belongs.

[0038] Beneficial effects

[0039] According to this disclosure, a large amount of equipment data can be organized based on data collection time data and equipment units. Furthermore, based on the data collection time data and the unit identifier (ID) of each equipment unit, equipment data from each device sensor can be mapped to coordinate data. In other words, coordinate data can be matched for each equipment unit, thereby enabling the analysis of the impact of equipment factors in each process.

[0040] Therefore, the reliability of tracking quality data during electrode manufacturing is improved.

[0051] The embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. Before describing the embodiments of this disclosure, the terms or expressions used in this specification and claims should not be construed as limited to their commonly understood meaning or their meaning as defined in a common dictionary, but should be understood according to the meaning and concepts corresponding to this disclosure, based on the principle that the inventors of the application can appropriately define the terms or expressions to best describe this disclosure.

[0052] Therefore, the embodiments described herein and the configurations shown in the accompanying drawings are merely examples of this disclosure and do not reflect the full technical concept of this disclosure. It should be understood that various equivalents and modifications may exist to replace these configurations as of the filing date of this application.

[0053] Where it is determined that a well-known configuration or function related to the description of this disclosure would obscure the subject matter of this disclosure due to unnecessary details, it will not be described in detail.

[0054] Since the embodiments of this disclosure are provided to more fully illustrate the disclosure to those skilled in the art, the shapes, dimensions, etc., of the components shown in the drawings may be exaggerated, omitted, or illustrated schematically for clarity. Therefore, it should not be construed that the dimensions or proportions of the components fully reflect their actual dimensions or proportions.

[0055] Figure 1 This is a schematic diagram of a monitoring data generation system according to one implementation method. Figure 2 An example is shown that represents the unit identifier (ID) of a device unit and reference information of the sensors belonging to that device unit.

[0056] The monitoring data generation system 10 may include a device unit 110, a controller 120, a unit ID allocation server 130, and a monitoring data generation server 140.

[0057] Device unit 110 can be defined as a means that is mounted along the electrode sheet ES and performs operations on the electrode sheet ES during movement of the electrode sheet ES. Therefore, means that only perform inspection or measurement without performing operations on the electrode sheet ES (e.g., an inspector or measuring device) may not be included in the device unit of this disclosure.

[0058] In this disclosure, an "electrode sheet" can be defined as a sheet material that moves while being "operated" by a device unit. In a narrow sense, an electrode sheet can be understood as a sheet material obtained after being coated with an electrode slurry. In a broad sense, an electrode sheet can include a sheet material that moves while being operated by a device unit before being coated with an electrode slurry. In this disclosure, not only the electrode sheet in the narrow sense but also the electrode sheet in the broad sense are considered electrode sheets. For example, in this disclosure, a sheet material that has not yet been coated with electrode slurry by a coating machine during the coating process can also be considered an electrode sheet to which the device unit will perform operations. Coated electrode sheets and electrode sheets in other processes after the coating process (e.g., rolling processes, slitting processes, notching processes, etc.) should also be understood to be included in the electrode sheets of this disclosure. That is, the monitoring data generation system of this disclosure is applicable to all processes (e.g., coating processes, rolling processes, slitting processes, notching processes, etc.) performed on the sheet material by the device unit during the movement of the sheet material.

[0059] In this document, the term "action" can be understood to include processing performed on an electrode sheet. Such processing can include physical, chemical, or other types of treatment. For example, the term "operation" can be understood to include processing such as unwinding an electrode sheet from an electrode roll or winding an electrode sheet into an electrode roll. Additionally, the term "operation" can be understood to include physical or chemical treatments, such as coating at least one surface of an electrode sheet with a slurry, drying at least one surface of an electrode sheet, flipping an electrode sheet from a top surface to a bottom surface, slitting an electrode sheet, pressurizing and heating an electrode sheet, and discarding defective portions of an electrode sheet.

[0060] In this disclosure, the term "device data" can be defined as data other than coordinate data obtained by sensors included in the device unit.

[0061] Therefore, the coordinate data obtained by the sensors (rotary encoders) of the equipment units such as winding machines or unwinding machines described below will be regarded as different from the equipment data in the following text. However, when a sensor other than a rotary encoder (e.g., a temperature sensor) is installed in the winding machine or unwinding machine, the temperature data obtained by the temperature sensor can be included in the equipment data.

[0062] Additionally, data obtained by sensors included in devices other than device unit 110 (e.g., inspectors or measuring devices) (inspection data or measurement data) will be considered different from device data. Furthermore, the device data included in the device unit may include data directly related to the electrode pads and data indirectly related to the electrode pads.

[0063] For example, assuming an electrode slurry is coated onto an electrode sheet by a coating machine (a unit in the coating process), the temperature of the electrode slurry represents the characteristics of the electrode sheet and can therefore be considered equipment data directly related to the electrode sheet. However, the RPM of the pump connected to the coating machine or the die gap (i.e., the distance between the coating machine and the electrode sheet) are not directly related to the characteristics of the electrode sheet. However, these parameters can be indirectly related to the state of the electrode sheet. As mentioned above, data that appears to have a lower correlation with the electrode sheet when obtained by sensors in the equipment unit can also be considered equipment data.

[0064] According to this disclosure, a large amount of equipment data can be correlated with each other, thereby enabling the tracking or prediction of the quality of electrode sheets, electrodes manufactured from such electrode sheets, and battery intermediates or battery products including such electrodes. For example, the effect of temperature measured by an equipment unit in the coating process, namely a dryer, on sheet thickness data obtained in the rolling process can be analyzed.

[0065] Figure 1 A system for generating monitoring data during the coating process is shown. However, this system is only one example; similar data can also be generated in other electrode manufacturing processes such as rolling and slitting. Figure 1 Identical or similar monitoring data.

[0066] exist Figure 1 In the coating process, the equipment unit 110 may include an unwinder 111 for unwinding the electrode sheet ES, a coating machine 112 for applying slurry, a dryer 113 for drying the electrode sheet ES, a slitting machine 114 for slitting the electrode sheet ES, and a winding machine 115 for winding the electrode sheet ES.

[0067] To simplify the explanation, Figure 1 The diagram shows the electrode sheet ES moving in a straight line between the unwinder 111 and the winding machine 115. However, the transport path of the electrode sheet ES is not limited to a straight line and may include other types of paths such as curves. Figure 1 The diagram shows a coating machine 113 positioned on the top surface of an electrode sheet ES, with one surface of the electrode sheet ES coated with electrode paste. When manufacturing a single-sided coated electrode sheet with only one surface coated with electrode paste, as... Figure 1 As shown, the coated electrode sheet can be moved to the winding machine 115 and wound by the winding machine 115.

[0068] However, when a so-called double-sided coated electrode sheet is manufactured by coating the two surfaces of the electrode sheet with electrode paste, the path along which the electrode sheet ES moves can be different.

[0069] For example, the top and bottom surfaces of an electrode sheet can be processed sequentially on a continuous process line. In this case, the movement path of the electrode sheet can be changed so that after the top surface of the electrode sheet ES is coated with electrode paste as it passes through the top coater, the electrode sheet ES is flipped so that the bottom surface of the electrode sheet ES is coated with electrode paste as it passes through the bottom coater. The electrode sheet ES, with electrode paste coated on both the top and bottom surfaces, can then be moved to a winding machine and wound by the winding machine.

[0070] exist Figure 1 In the process of performing double-sided coating, additional equipment units, such as electrode flipping equipment, bottom coating machine and bottom dryer, can be installed after the dryer 113 for drying the electrode sheet.

[0071] therefore, Figure 1 The device unit shown is only an example; fewer or more device units can be installed depending on the electrode plate path or processing steps.

[0072] Each device unit may include at least one sensor for obtaining device data. That is, each device unit may include at least one sensor.

[0073] The inclusion of sensors in a device unit should not be interpreted as meaning that the device unit and sensors are necessarily installed close to each other. It is understood that a sensor is included within a device unit when it is installed in a location capable of sensing the processing effect after processing by that particular device unit.

[0074] Furthermore, the multiple sensors included in a device unit do not necessarily need to be installed in the same location. Even within the same device unit, the sensors may be in the same or different locations. However, for ease of explanation, this disclosure assumes that sensors belonging to the same device unit are in the same location.

[0075] exist Figure 1 In this process, the unwinding machine 111 may include a first rotary encoder SE1 as a sensor.

[0076] exist Figure 1 In the winding machine 115, a second rotary encoder SE2 may be included as a sensor.

[0077] The first rotary encoder SE1 and the second rotary encoder SE2 are configured to obtain coordinate data by measuring the unwinding and winding amounts of the electrode sheets. As mentioned above, the coordinate data is not included in the device data. If another sensor is installed in the unwinder 111 or the winding machine 115, the data sensed by that sensor, which is not coordinate data, can be the device data of the unwinder 111 or the winding machine 115.

[0078] The first electrode roll ER1 can be mounted on the unwinder 311. The unwinder 111 can be configured to unwind the electrode sheet ES from the first electrode roll ER1.

[0079] The winding machine 115 can wind the electrode sheet ES into a second electrode roll ER2. The electrode sheet ES can be wound into the second electrode roll ER2 and cut and separated after reaching a certain winding length. Therefore, the electrode sheet ES can move between the unwinding machine 111 and the winding machine 115.

[0080] The first rotary encoder SE1 can be configured to sense the amount of electrode sheet ES unwound from the first electrode roll ER1 by the unwinder 111. Therefore, the first rotary encoder SE1 can be configured to generate an unwinding amount signal UWAS representing the amount of unwinding of the electrode sheet ES. The first rotary encoder SE1 can be configured to send the unwinding amount signal UWAS to the controller 120. The controller 120 can be configured to collect unwinding amount data based on the unwinding amount signal UWAS of the electrode sheet ES.

[0081] The second rotary encoder SE2 can be configured to sense the amount of electrode sheet ES wound into the second electrode roll ER2 by the winding machine 115. Therefore, the second rotary encoder SE2 can be configured to generate a winding amount signal WAS representing the amount of winding of the electrode sheet ES. The second rotary encoder SE2 can be configured to send the winding amount signal WAS to the controller 120. The controller 120 can be configured to collect winding amount data based on the winding amount signal WAS of the electrode sheet ES.

[0082] exist Figure 1 In this process, the coating machine 112 discharges electrode slurry and coats the electrode sheet ES with the electrode slurry. The coating process is the process of applying coating materials such as electrode slurry onto the electrode sheet ES. The electrode slurry may include electrode active materials, conductive agents, binders, and solvents. The electrode slurry can be provided by dissolving the electrode active materials, conductive additives, binders, etc., in a solvent.

[0083] The coating machine 112, as one of the equipment units, may include, for example, three sensors Sa, Sb, and Sc in the same location (alternatively, the locations of these three sensors may be different from each other). The three sensors Sa, Sb, and Sc can respectively acquire equipment data EDa, EDb, and EDc related to the coating machine 112. Sa can be an RPM sensor, and for example senses the RPM of a pump connected to the coating machine. EDa is the equipment data sensed by Sa, and can be RPM. Sb can be a temperature sensor, and for example senses the temperature of the electrode slurry discharged from the coating machine or the temperature of the electrode slurry applied to the electrode sheet. EDb is the equipment data sensed by Sb, and can be temperature. Sc can be a distance measurement sensor, and for example measures the die gap, i.e., the distance between the coating machine and the electrode sheet. EDc is the equipment data sensed by Sc, and can be temperature.

[0084] Dryer 113, as one of the device units, can be installed on the electrode sheet after coating machine 112 to heat and dry the coated electrode sheet. Dryer 113 may include two sensors, Sd and Se, in the same location (or the two sensors may be located in different positions). The two sensors, Sd and Se, can each acquire device data related to dryer 113. For example, Sd or Se can be, but is not limited to, sensors that measure temperature, humidity, and hot air velocity in dryer 113. EDd is the device data sensed by sensor Sd, and Ede is the device data sensed by sensor Se.

[0085] The slitting machine 114, as one of the equipment units, can slit the electrode sheet dried by the dryer into multiple parts. As described above, in the case of double-sided coated electrode sheets with slurry coated on both the top and bottom surfaces, additional equipment units (e.g., electrode sheet flipping equipment, bottom coating machine, and bottom dryer) can be installed between the dryer 113 and the slitting machine 114.

[0086] The slitting machine 114 may include, for example, a sensor Sf. Sf may also acquire device data related to the slitting machine 114. EDf is the device data sensed by the sensor Sf.

[0087] The number of sensors and the data measured by each sensor described above are merely examples. The number of sensors or data can be varied. Other parameters, such as CTP (critical to parameter) that may have a significant impact on the electrode manufacturing process, or other parameters that meet the above-described device data definition, can also be sensed as device data.

[0088] For ease of illustration, Figure 1Only one winding machine 115 is shown in this disclosure. However, when the electrode sheet ES is cut into multiple parts using a slitting machine 114, multiple winding machines 115 can be provided in a number corresponding to the number of these parts of the electrode sheet ES. In this case, all of the multiple winding machines 115 can be a device unit. In addition, the amount of electrode sheet ES wound by each winding machine 115 into each second electrode roll ER2 can be sensed by the second rotary encoder SE2 of each winding machine 115. Each second rotary encoder SE2 can generate a winding amount signal WAS representing the winding amount of each part of the electrode sheet ES. However, regardless of whether there is one or multiple winding machines 115, the principle of measuring the winding amount and collecting the coordinate data of each electrode sheet, as described below, is the same. Therefore, in this disclosure, only one winding machine 115 is shown for ease of illustration.

[0089] Controller 120 can be configured to control the operation of device units 111, 112, 113, 114, and 115. Controller 120 is capable of controlling all device units among multiple device units in the electrode manufacturing process, and therefore can be referred to as an integrated controller. Controller 120 can be configured to generate signals for operating or stopping device units 111, 112, 113, 114, and 115. Signals for operating or stopping device units 111, 112, 113, 114, and 115 can be generated based on a body including product ID and manufacturing formula details.

[0090] The device data ED obtained by each device unit can be sent to the controller 120. For example, a location, i.e., an address, for storing the device data obtained by each sensor can be set in a data memory such as a memory in the controller 120. At this address, the device data obtained by each sensor can be stored continuously or at time intervals.

[0091] Device data ED sent to controller 120 can be sent to unit ID allocation server 130 at time intervals.

[0092] As described above, the controller 120 can collect unwinding amount data based on the unwinding amount signal UWAS of the electrode sheet ES, or collect winding amount data based on the winding amount signal WAS.

[0093] The controller 120 can be configured to collect coordinate data CD of the electrode sheet ES based on one of the winding amount signal WAS and the unwinding amount signal UWAS. For example, the controller 120 can determine the distance the electrode sheet ES has moved in the current process based on the winding amount signal WAS. Therefore, at each time point in the coating process, coordinates representing the relative position of a portion of the electrode sheet ES that will be wound by the winding machine 115 can be determined.

[0094] In addition, the controller 120 can collect the coordinate data of the electrode sheet when the sensor senses the device data.

[0095] The coordinate data of the sensor sensing the device data can be obtained by adding or subtracting the first offset length from the unwinding or winding amount of the electrode sheet during sensing.

[0096] For example, suppose that at a certain time (e.g., 9:40:51) when the sensors of the coating machine 112, the dryer 113, and the slitting machine 114 are sensing equipment data, the winding amount of the electrode sheet sensed by the second rotary encoder SE2 of the winding machine 115 is 1204 m. In this case, since the positions of the equipment units or sensors are different from each other, even if the winding machine senses the winding amount of the electrode sheet at the same time, the position of the electrode sheet at the sensor is different from that winding amount. Specifically, the position of the electrode sheet at the sensor differs from that winding amount by a first offset length OD1, OD2, OD3, and OD4.

[0097] The first offset lengths OD1, OD2, OD3 and OD4 can be defined as the lengths of the electrode sheet between the unwinding or winding machine carrying the electrode sheet and the respective portions of the electrode sheet where each sensor is located.

[0098] Using the winding amount of the winding machine as a reference value, the electrode position at the sensing time point of each sensor is calculated by adding a first offset length to the winding amount. In this case, the first offset length can be defined as the length of the electrode between the winding machine containing the electrode and the portion of the electrode where the sensor is located.

[0099] For example, when the first offset length OD2 of the sensor used for the coating machine 112 is 50 m, the electrode plate position of the sensor of the coating machine 112 at 09:40:51 is 1254 m.

[0100] When the first offset length OD3 of the sensor used in dryer 113 is 30 m, the electrode plate position of the sensor of dryer 113 that obtains device data at the same time is 1234 m.

[0101] When the first offset length OD4 of the sensor used for the slitting machine 114 is 10 m, the position of the sensor on the electrode plate at which the device data is obtained at 09:40:51 is 1214 m.

[0102] The first offset length is determined based on the installation position of each device unit, and is therefore preset for each device unit.

[0103] Therefore, the corresponding coordinate data CD of the electrode sheet when the sensor of each device unit senses the device data can be obtained by adding the first offset length to the winding amount of the winding machine.

[0104] Similarly, the first offset length OD1 of the sensor used for the unwinder 111 is known, and the coordinate data of the electrode sheet on the unwinder 111 can be obtained by adding OD1 to the winding amount.

[0105] On the other hand, the coordinate data CD of the electrode sheet when the sensor senses the device data ED can also be obtained using the unwinding amount of the unwinding machine. In this case, the first offset length can be defined as the length of the electrode sheet between the unwinding machine carrying the electrode sheet and the portion of the electrode sheet where the sensor is located. In this case, the coordinate data can be obtained by adding or subtracting the first offset length from the unwinding amount of the electrode sheet when the sensor senses the data.

[0106] The following description of this disclosure will focus on an example of obtaining coordinate data CD relative to a winding machine.

[0107] The corresponding coordinate data CD of the electrode plate when the sensor of each device unit senses the device data ED can be calculated based on the first offset length as described above and collected by the controller 120.

[0108] The controller 120 can be configured with a memory or other data storage device to store the coordinate data of the electrode at the specified time point of each sensor sensing device. At this address, the corresponding coordinate data of the electrode can be stored continuously or at time intervals.

[0109] The controller 120 can communicate operationally with the first rotary encoder SE1 and the second rotary encoder SE2, sensors Sa, Sb, Sc, Sd, Se and Sf, or device units 112, 113 and 114 via a wired or wireless data network. The data network can be unidirectional or bidirectional. The data network can be implemented via physical channels, WiFi, public networks and / or dedicated networks using Bluetooth or other frequency bands.

[0110] The coordinate data CD collected by the controller 120 can be sent to the unit ID allocation server 130 at time intervals.

[0111] In this embodiment, each sensor in the device unit acquires device data ES, but does not match the device data ED with the corresponding coordinate data CD of the electrode sheet. Therefore, no additional processor is needed for coordinate data matching. Furthermore, since the device data and coordinate data are not matched at a lower level of the system, no data processing load is generated, allowing the sensed device data ED or coordinate data CD to be quickly sent to the controller. Similarly, the device data or coordinate data collected by the controller can also be quickly sent to the unit ID allocation server 130.

[0112] The unit ID allocation server 130 is a server used to assign the unit ID (UI) of a device unit to the device data (ED) and coordinate data (CD). The unit ID allocation server 130 can be an IoT device, or it can be an eIoT server that can be accessed by an eIoT device.

[0113] The unit ID allocation server 130 can receive device data ED and coordinate data CD from the controller 120 at time intervals. For example, the unit ID allocation server 130 can receive device data ED and coordinate data CD from the controller 120 at intervals of 0.1, 0.2, 0.3, 0.5, 1, and 2 seconds. The time interval is not limited to these. The shorter the data collection time interval, the higher the data reliability, but the amount of data to be processed may increase. The longer the data collection time interval, the smaller the amount of data to be processed, but the data reliability may decrease. The time interval can be appropriately determined by considering the target data reliability, the amount of data to be processed, the specifications of the electrode or battery product, the load applied to the battery manufacturing system, etc. In this embodiment, it is assumed that the unit ID allocation server 130 receives device data ED and coordinate data CD once per second. When the unit ID allocation server 130 collects data once per second, the time value at which the data is acquired is also naturally obtained. That is, the device data ED and coordinate data CD can be associated with the time data TD at which each data is acquired.

[0114] Therefore, the unit ID allocation server 130 can collect device data ED and time data TD (hereinafter referred to as collection time data) when collecting device data ED.

[0115] In addition, the unit ID allocation server 130 can also collect the coordinate data CD of the electrode sheet when the sensor senses the data of the device, as well as the time data TD when the coordinate data is obtained.

[0116] The location, i.e., the address, for storing device data obtained by each sensor can be set in the data storage, such as the memory, in the unit ID allocation server 130. At this address, the device data obtained by each sensor can be stored at time intervals.

[0117] The location, i.e., the address, for storing the corresponding coordinate data of the electrode pads at a given time point in the data sensing data of each sensor can be set in the memory or other data storage of the unit ID allocation server 130. At this address, the corresponding coordinate data of the electrode pads can be stored at time intervals.

[0118] Figure 2 An example of reference information stored in the unit ID allocation server 130 is shown. The reference information may include the identifier of the device unit, i.e., the unit ID UI, and the correspondence between it and the sensors belonging to that unit ID. (Refer to...) Figure 2 As can be seen, the three sensors Sa, Sb, and Sc correspond to a device unit with UI #1 (e.g., a coating machine). (See reference...) Figure 2 As can be seen, the two sensors Sd and Se correspond to a device unit with UI #2 (e.g., a dryer). (See reference...) Figure 2 As can be seen, a sensor Sf corresponds to a device unit (e.g., a half-splitter) with UI #3. Figure 2 This is just an example; the reference information may include the correspondence between the unit IDs of other device units and the sensors belonging to those device units. Therefore, the sensor type, number of sensors, etc., corresponding to a unit ID can be identified by referring to the reference information.

[0119] The reference information may also include information about the units of the data (parameters) sensed and acquired by each sensor. To store the reference information, the unit ID allocation server 130 may include a database (DB).

[0120] The unit ID allocation server 130 assigns the unit ID UI to the device data ED and the collected time data TD based on the reference information.

[0121] Figures 3 to 5 The diagram illustrates the assignment of unit IDs to device data and the collection time data of that device data, as well as coordinate data and the collection time data of that coordinate data.

[0122] Reference Figure 3 (a) Based on reference information, unit ID #1 is assigned to device data EDa, EDb, and EDc obtained from three sensors, as well as the time data TD at which device data EDa, EDb, and EDc are collected. The data collection interval is 1 second. The device data EDa collected at each time point are a1, a2, a3, and a4. The device data EDb collected at each time point are b1, b2, b3, and b4. The device data EDc collected at each time point are c1, c2, c3, and c4. Since #1 is assigned to the aforementioned device data, it can be seen that this device data is obtained from a device unit (e.g., coating machine 112) with unit ID #1.

[0123] Reference Figure 3 (b) Assigns unit ID #1 to the coordinate data of the electrode sheet when the three sensors sense device data, and the time data TD when collecting this coordinate data. The data collection interval is 1 second. As described above, the coordinate data can be obtained by adding a first offset length to the unwinding amount of the electrode sheet. That is, by adding the first offset length defined for the sensor of each device unit, the coordinate data of the electrode sheet of each device unit when the sensor senses device data can be obtained. For example, when the winding amount at 9:40:51 is 1204 m, and the first offset length for the three sensors is 50 m, the coordinate data of the electrode sheet corresponding to the device data obtained at that time is 1254 m.

[0124] In the same way, coordinate data at each time point can be obtained. For example... Figure 3 As shown in (b), it can be seen that the electrode sheet moves at a speed of 1 m per second during the process.

[0125] In this way, the coordinate data at the time point of the sensing device data of each sensor can be obtained by defining a first offset length for each sensor. Therefore, the coordinate data of the electrode plate corresponding to each device unit can be obtained, and the unit ID of each device unit can also be mapped to this coordinate data.

[0126] exist Figure 4 In (a), unit ID #2 is assigned to device data EDd and EDe obtained by sensors Sd and Se belonging to the device unit (e.g., dryer 113) and time data TD collected.

[0127] exist Figure 4 In (b), unit ID #2 is assigned to the coordinate data of the electrode corresponding to the time points of the sensing device data EDd and EDe of the sensors Sd and Se, as well as the time data TD when the coordinate data is collected.

[0128] Since the first offset length defined for sensors Sd and Se is 30 m, when the winding amount at 9:40:51 is 1204 m, the coordinate data of the electrode sheet corresponding to the device data obtained at that time is 1234 m.

[0129] exist Figure 5 In (a), unit ID #3 is assigned to device data EDf obtained by sensor Sf belonging to device unit (e.g., half-splitter 114) and time data TD collected.

[0130] exist Figure 5In (b), the unit ID #3 is assigned to the coordinate data of the electrode corresponding to the time point of the sensor Sf sensing device data EDf, and the time data TD when the coordinate data is collected.

[0131] Since the first offset length defined for sensor Sf is 10 m, when the winding amount at 9:40:51 is 1204 m, the coordinate data of the electrode sheet corresponding to the device data obtained at that time is 1214 m.

[0132] In the unit ID allocation server 130, instructions, i.e., programs, regarding the unit ID allocation process can be stored in memory. The unit ID allocation server 130 may include at least one processor for executing these instructions.

[0133] The amount of device data collected by the unit ID allocation server 130 can grow exponentially depending on the number of device units and the number of sensors in each device unit. Furthermore, the unit ID allocation server 130 should coordinate with the controller 120 to continuously collect data collected by the controller 120 at time intervals. Therefore, despite the need to collect and process a large amount of data, the data processing capacity of the unit ID allocation server 130 is limited. Therefore, it is efficient for the unit ID allocation server 130 to only perform the task of assigning unit IDs to device data and coordinate data, i.e., attaching information tags as unit IDs, while data monitoring using these information tags is performed by the higher-level server.

[0134] Figures 6 to 8 An example of matching device data with coordinate data based on collection time data and unit ID is shown.

[0135] The monitoring data server 140 can generate monitoring data by matching device data ED with coordinate data CD based on the collected time data TD and unit ID UI.

[0136] Figure 6 It shows the basis Figure 3 (a) and Figure 3 The unit ID #1 and time data TD assigned in (b) will be matched with the device data EDa, EDb and EDc obtained by the three sensors of the device unit belonging to unit ID #1 and the coordinate data CD of the electrode plate at the time point of sensing the device data.

[0137] Figure 7 It shows the basis Figure 4 (a) and Figure 4The unit ID #2 and time data TD assigned in (b) will be matched with the device data EDd and EDe obtained by the two sensors of the device unit belonging to unit ID #2 with the coordinate data CD of the electrode plate at the time point of sensing the device data.

[0138] Figure 8 It shows the basis Figure 5 (a) and Figure 5 The unit ID #3 and time data TD assigned in (b) will be matched with the device data EDf obtained by a sensor belonging to the device unit of unit ID #3 and the coordinate data CD of the electrode at the time point of sensing the device data.

[0139] like Figure 7 and Figure 8 As shown, device data and coordinate data can be continuously obtained over time. Figure 7 and Figure 8 The sensor data acquired by the device units with unit IDs #2 and #3 is shown until the coordinates of the electrode plate reach 1253 m.

[0140] Figure 9 It shows the basis Figures 6 to 8 Partial X, Y, and Z coordinate data, along with the corresponding unit ID, device data, and collection time data for the same coordinate data.

[0141] Based on coordinate data, the monitoring data generation server 140 can generate monitoring data by mapping at least one of the following: at least one unit ID corresponding to the same coordinate data, device data of at least one sensor belonging to each of the at least one unit ID, and at least one piece of collected time data.

[0142] Reference Figure 9 The unit ID of each device unit corresponding to the coordinate 1253 m of the same electrode sheet, the device data obtained by the sensor of each device unit, and the time data when the device data was obtained are matched with each other.

[0143] exist Figures 6 to 8 In the middle, data is aligned based on time, while... Figure 9 In this process, data is aligned based on coordinates. In either case, because the data and unit IDs are mapped to each other, the relationship between the device data and electrode positions associated with each device unit can be clearly understood.

[0144] exist Figure 9 In this process, since the equipment data obtained by each equipment unit at the same position (coordinate) on the electrode sheet are related to each other, it is easy to grasp the influence of the process parameters of each equipment unit when manufacturing the same part of the electrode sheet.

[0145] Monitoring data may include rollouts.

[0146] The roll diagram is a visualization tool proposed by the applicant for efficiently representing electrode sheets or electrodes. The roll diagram can represent an electrode sheet ES based on coordinates indicating its position on the electrode sheet ES. The roll diagram can include data representing the history of processes performed on the electrode sheet ES and related to the coordinates. Therefore, as described below, the roll diagram enables feedback, feedforward, and tracking of secondary battery manufacturing processes.

[0147] The electrode manufacturing process for secondary batteries involves a series of roll-to-roll operations. For feedforward, time-series data should be correlated with the locations of workpieces, components, intermediate products, and finished products in the real world. Roll diagrams can correlate time-series data with coordinate data, including the location coordinates of workpieces, components, intermediate products, and finished products in the real world. Roll diagrams can provide matching between time-series data and real-world workpieces, components, intermediate products, and finished products based on coordinate data. Therefore, roll diagram generation and feedforward can improve productivity and quality by digitizing and objectifying process aspects that depend on operator judgment. The roll diagrams from previous batches can be used to improve subsequent batches of processes, and this behavior can be referred to as process feedback. Process feedback using roll diagrams can include identifying process conditions and parameters that lead to problems and defects based on the data included in the roll diagrams.

[0148] Furthermore, roll patterns can be generated for workpieces, intermediate products, and finished products at each unit process stage to track the manufacturing history of products on the market (e.g., battery cells, battery modules, or battery packs). For example, a battery cell may include a cell ID formed on the electrode assembly or housing. The cell ID may include the batch number and coordinate information of the electrodes and separators included in the battery cell. In other words, the cell ID can be associated with a roll pattern of the electrodes and separators included in the battery cell. Therefore, when an event such as a quality problem occurs in a battery cell on the market, the manufacturing history data of the battery cell can be retrieved based on the cell ID.

[0149] In addition, such as Figures 1 to 9 The equipment data shown can be correlated with data included in the roll pattern (e.g., inspection data or measurement data). For example, equipment data such as the temperature of the electrode slurry or the RPM of the pump can be correlated with load measurement data measured by a load meter. Equipment data can be correlated with load measurement data for each electrode manufacturing process, such as coating, rolling, and slitting. The quality of the produced electrodes or batteries can be analyzed or predicted by correlating equipment data with roll pattern data between processes. Alternatively, the equipment data according to this disclosure can be included in the roll pattern data.

[0150] Therefore, according to one embodiment of this disclosure, the impact of each device's data on the electrode (sheet) can be determined based on time and coordinates by comparing the data of each device with each other. Furthermore, the impact of each data point on the electrode (sheet) can be more comprehensively identified by combining the device data, inspection data, and measurement data included in the roll plot. Thus, quality traceability can be further improved, and data reliability and consistency can be significantly enhanced by utilizing monitoring data.

[0151] The monitoring data generation server 140 can be, for example, a data warehouse, and can store coordinate-related data and unit ID-related data for a long period of time based on product quality guarantee period, etc.

[0152] Figure 10 The diagram schematically illustrates the unit ID of the device unit mounted on the top and bottom surfaces of the electrode sheet, the sensor, and the device data obtained by the sensor.

[0153] Figure 10 This illustrates a double-sided coating process in which electrode paste is applied to opposite sides of an electrode sheet. In this process, the electrode sheet, moving between the unwinder 111 and the winding machine 115, can move along a path that flips the top and bottom surfaces of the electrode sheet. That is, the top and bottom surfaces of the electrode sheet can be processed sequentially along the path of the electrode sheet on a continuous process line.

[0154] exist Figure 10 In this process, equipment units such as a top coater and a top dryer can be installed on the top surface of the electrode. On the other hand, equipment units such as a bottom coater, a bottom dryer, and a half-slitting machine can be installed on the lower surface side of the electrode.

[0155] The device unit on the top surface of the electrode, the sensor belonging to the first device unit, and the device data measured by the first sensor can be referred to as the first device unit, the first sensor S1, and the first device data ED1, respectively. In this case, the unit ID of the first device unit can be referred to as the first unit ID UI1.

[0156] The device unit on the bottom surface of the electrode, the sensor belonging to the second device unit, and the device data measured by the second sensor can be referred to as the second device unit, the second sensor S2, and the second device data ED2, respectively. In this case, the unit ID of the second device unit can be referred to as the second unit ID UI2.

[0157] like Figures 3 to 5 The diagram shows the assignment of unit IDs to device data and coordinate data, such as... Figures 6 to 8 The diagram shows the matching of device data with coordinate data based on collected time data and unit ID, and as shown... Figure 9 The diagram shows how to match the unit ID, device data, and time data corresponding to the same coordinate data. This can also be done in... Figure 10 It is performed in the process.

[0158] For example, when a top coating TC is formed on the top surface of an electrode sheet by a first device unit (e.g., a top coating machine), and a first sensor S1 included in the top coating machine obtains first device data ED1, the coordinates on the electrode sheet at the time point when the first device data ED1 is obtained can be matched with UI1 and ED1.

[0159] When a bottom coating BC is formed on the bottom surface of an electrode sheet by a second device unit (e.g., a bottom coating machine), and the second sensor S2 included in the bottom coating machine obtains the second device data ED2, the coordinates on the electrode sheet at the time point when the second device data ED2 is obtained can be matched with UI2 and ED2.

[0160] After the top surface is coated, the electrode sheet is moved to a distance between the top and bottom coaters, and then the bottom surface of the electrode sheet is coated. In other words, the time points for obtaining ED1 and ED2 can be different from each other.

[0161] However, as Figure 9 As shown, when the coordinate data of the electrode plates at the time points of sensing ED1 and ED2 are the same, the data can be aligned based on the coordinate data.

[0162] The fact that the coordinate data at the same time point is the same should be understood as the part of the electrode sheet with the top coating TC and the part of the electrode sheet with the bottom coating BC corresponding to each other in the vertical direction.

[0163] In this case, the monitoring data generation server 140 can match the first device data ED1 sensed by at least one first sensor S1 at a position on the top surface of the electrode sheet corresponding to the same coordinate data of the electrode sheet, and the first unit ID UI1 of the first device unit to which the first sensor S1 belongs with the coordinate data.

[0164] In addition, the monitoring data generation server 140 can match the second device data ED2 sensed by at least one second sensor S2 at a position corresponding to the same coordinate data on the bottom surface of the electrode sheet, and the second unit ID UI2 of the second device unit to which the second sensor S2 belongs with the coordinate data.

[0165] Therefore, ED1, UI1, ED2, and UI2 are matched based on the same coordinate data. Thus, when manufacturing electrodes by cutting portions of electrode sheets with coatings TC and BC formed, the quality of the electrode or the battery including that electrode can be analyzed based on the matched data.

[0166] Figure 11This is a schematic diagram illustrating the process of manufacturing electrodes from electrode sheets, where each electrode is assigned an electrode ID.

[0167] For example, in the lamination or winding process, electrodes can be manufactured by cutting electrode sheets that move during the process according to standards. The manufactured electrodes can be combined with electrodes of different polarities to form electrode assemblies.

[0168] Electrode IDs can be assigned to electrodes. Electrode IDs can be assigned physically or virtually to actual electrodes. For example, an electrode ID can be assigned to the tab 2 of an electrode. Figure 11 In this context, the electrode ID is represented by the special character @ and numbers (e.g., @1, @2, and @3), but the implementation is not limited to this. The electrode ID can be represented by electronic codes such as barcodes or QR codes or other forms of identification information.

[0169] Electrode ID can be associated with, for example Figure 11 The coordinate data of the position of the electrode or electrode sheet in the electrode manufacturing process shown, or the position of the electrode sheet from which the electrode is obtained in the processing process, are associated. Each electrode ID can be associated with the coordinate data at each position. Figure 10 In this context, it is assumed that electrode ID @1 is associated with coordinate data CD1.

[0170] In this case, at least one sensor can sense equipment data in multiple processes at the position on the electrode sheet corresponding to the coordinate data CD1.

[0171] Therefore, electrode ID @1 and coordinate data CD1 can be matched with device data ED sensed by at least one sensor at the coordinate data location on the electrode sheet and the unit ID of the device unit to which the sensor belongs. This matching can be achieved through... Figures 3 to 9 The matching process shown is executed.

[0172] The electrode can be a double-sided coated electrode, with electrode paste coated on both the top and bottom surfaces. In other words, the electrode can be made of... Figure 10 Double-sided coated electrodes are manufactured from double-sided coated electrode sheets.

[0173] In this case, electrode ID @1 and coordinate data CD1 can be matched with device data and unit IDs for the top and bottom surfaces of the electrode sheet.

[0174] In other words, electrode ID @1 can be matched with first device data ED1 sensed by at least one first sensor at a position corresponding to coordinate data CD1 on the top surface of the electrode sheet, and the first unit ID UI1 of the first device unit to which the at least one first sensor belongs.

[0175] It can also be matched with the second device data ED2 sensed by at least one second sensor at a position corresponding to the coordinate data CD1 on the bottom surface of the electrode sheet, and the second unit ID UI2 of the second device unit to which the at least one second sensor belongs.

[0176] Therefore, by analyzing the electrode ID and other matching data, as well as analyzing the device data related to the electrode, it is possible to efficiently analyze or predict electrode quality information.

[0177] Figure 12 This is a flowchart of a monitoring data generation method according to one implementation method.

[0178] The monitoring data generation method may include: Collect device data sensed by at least one sensor of each of the multiple device units mounted along the electrode sheet (P10). When the at least one sensor senses the device data, coordinate data indicating the position on the electrode sheet is collected (P20). Assign the unit ID of the device unit to which the at least one sensor belongs to the device data and the time data when the device data is collected, and assign the unit ID of the device unit to which the at least one sensor belongs to the coordinate data and the time data when the coordinate data is collected (P30); and Based on the collected time data and the unit ID, monitoring data is generated by matching the device data with the coordinate data (P40).

[0179] In P10, multiple electrode units can be mounted along the electrode sheet. Each device unit may include at least one sensor. The sensor can sense device data. The sensed device data can be collected by the controller 120. The device data collected by the controller 120 can be collected at time intervals by the unit ID allocation server 130.

[0180] In P20, the coordinate data of the electrode sheet can be collected when the sensor senses data from the device. The coordinate data can be collected based on the unwinding amount signal or the winding amount signal of the electrode sheet. The unwinding amount signal of the electrode sheet can be obtained by a first rotary encoder SE1 mounted on the unwinding side. The winding amount signal of the electrode sheet can be obtained by a second rotary encoder SE2 mounted on the winding side. The unwinding amount signal and / or the winding amount signal can be collected by the controller 120.

[0181] Coordinate data when the sensor senses data from the device. The first offset length can be obtained by adding or subtracting the unwinding or winding amount of the electrode sheet during sensing. The first offset length is the length of the electrode sheet between the unwinding or winding machine carrying the electrode sheet and the portion of the electrode sheet where the sensor is located. Therefore, for example, the coordinate data of the electrode sheet at the time point when each sensor performs sensing can be obtained by adding the first offset length determined for each sensor to the winding amount obtained by the second rotary encoder SE2.

[0182] The coordinate data collected by the controller 120 can be collected at time intervals by the unit ID allocation server 130.

[0183] In P30, the unit ID allocation server 130 can collect device data and coordinate data at time intervals and associate the time data when collecting each device data and coordinate data with the device data and coordinate data.

[0184] The unit ID allocation server 130 can assign the unit ID of the device unit to which each sensor belongs to the device data and the time data when collecting the device data. The unit ID allocation server 130 can also assign the unit ID of the device unit to which each sensor belongs to the coordinate data and the time data when collecting the coordinate data.

[0185] The unit ID allocation server 130 can allocate unit IDs to device data and collected time data based on reference information, which includes the correspondence between the unit IDs of each device unit and the sensors belonging to each device unit.

[0186] In P40, the monitoring data generation server 140 can generate data based on the collected time data and unit ID, such as... Figures 6 to 8 The diagram shows how monitoring data is generated by matching device data with coordinate data.

[0187] like Figure 9 As shown, the monitoring data generation server 140 can generate monitoring data by mapping at least one of the following: at least one unit ID corresponding to the same coordinate data, device data of at least one sensor belonging to each of the at least one unit ID, and at least one piece of collected time data.

[0188] Monitoring data can also be generated during the electrode manufacturing process, in which the top and bottom surfaces of the electrode sheet are processed sequentially on a continuous process line.

[0189] The monitoring data generation server 140 can match the first device data sensed by at least one first sensor at a position corresponding to the same coordinate data of the electrode sheet on the top surface of the electrode sheet, and the first unit ID of the first device unit to which the at least one first sensor belongs with the coordinate data.

[0190] In addition, the monitoring data generation server 140 can match the second device data ED2 sensed by at least one second sensor at a position corresponding to the same coordinate data on the bottom surface of the electrode sheet, and the second unit ID of the second device unit to which the at least one second sensor belongs with the coordinate data.

[0191] Figure 13 A computing system is shown that performs an operation method of a unit ID allocation server 130 or a monitoring data generation server 140 according to an embodiment of the present disclosure.

[0192] Reference Figure 13 According to one embodiment, the computing system 20 may include a server controller 21, a memory 22, an input / output device 23, and a communication interface 24.

[0193] Server controller 21 may be, for example, a microcontroller (MCU). A microcontroller is an ultra-small controller that embeds a minimal number of computing elements, such as a processor, memory, and input / output buses, into an integrated circuit; it typically refers to a computing device designed for embedded applications. In some implementations, the processor may include both a CPU and a GPU.
