Description

Technical Field

[0001] This disclosure relates to a roll pattern creation system, and more specifically to a roll pattern creation system that ensures the traceability of electrode-related data, thereby enabling accurate analysis and reducing working time.

[0002] This application claims priority to Korean Patent Application No. 10-2023-0103705, filed on August 8, 2023, the entire contents of which are incorporated herein by reference. Background Technology

[0003] With technological advancements and increasing demand for mobile devices, the demand for rechargeable batteries is also rapidly growing. Among them, lithium-ion rechargeable batteries are widely used as power sources for various mobile devices and electronic products due to their high energy density, high operating voltage, and excellent storage and lifespan characteristics.

[0004] An electrode manufacturing process for manufacturing electrodes for lithium secondary batteries includes: a coating process for applying active materials and predetermined insulating materials to the surface of a metal electrode plate serving as a current collector to form a positive electrode and a negative electrode; a rolling process for winding the coated electrodes; a slitting process for cutting the wound electrodes according to dimensions; and a grooving process for forming tabs on the electrodes.

[0005] When tabs are formed in the grooving process, electrode assemblies are formed by inserting a separator between the positive and negative electrodes. These are then assembled into a secondary battery. In the assembly process, the electrode assemblies are stacked or folded, encapsulated in bags or cans, and filled with electrolyte. The assembled secondary battery is then charged and discharged through an activation process that assigns battery characteristics to become the final product, the secondary battery.

[0006] This process can be performed through a series of roll-to-roll processes. However, because the electrode's starting point and / or surface are reversed and its length is changed, the coordinates of the roll pattern created for each process may not match. Therefore, even if a roll pattern is created for each unit process, it may be difficult to trace the source of the problem by comparing it with the roll pattern of the final remaining electrode. Summary of the Invention

[0007] Technical issues

[0008] This disclosure relates to providing a roll pattern creation system that ensures the traceability of electrode-related data and enables accurate analysis and reduced work time.

[0009] Technical solution

[0010] To address this technical problem, this disclosure provides a roll pattern creation system for a series of sequentially repeated roll-to-roll processes, in which electrodes unwound from a dewinder are moved to be wound in a rewinder. The roll pattern creation system includes a roll pattern creation device for creating a roll pattern for each process. The roll pattern is defined in a coordinate plane having two axes: a longitudinal axis of the electrode and a width axis of the electrode. The position of the electrode in each process is represented by coordinate values ​​in the coordinate plane. The roll pattern creation device includes a roll pattern matching unit for matching the roll pattern created from the series of roll-to-roll processes. The coordinate values ​​of the roll pattern of each process preceding the final process are matched with the coordinate values ​​of the roll pattern of the final process, such that the physical electrode represented by the roll pattern of the final process is matched with the physical electrode represented by the roll pattern of each process preceding the final process, wherein the electrode includes two or more lanes arranged on the axis of the width direction, and wherein, when the rewinder of the first roll-to-roll process winds the electrode in the up-down direction opposite to the unwinder of the second roll-to-roll process following the first roll-to-roll process unwinds the electrode in the up-down direction, the roll pattern matching part matches the upper portion of the roll pattern of the first roll-to-roll process with the lower portion of the roll pattern of the second roll-to-roll process.

[0011] In some exemplary embodiments, the roll pattern creation system may further include a storage device capable of storing batch information including the winding direction of the electrodes.

[0012] In some exemplary embodiments, the roll pattern matching unit may be configured to match the roll pattern of the first roll-to-roll process with the roll pattern of the second roll-to-roll process after reversing the channel sequence of the roll pattern in the width direction when the rewinder of the first roll-to-roll process winds the electrode in the vertical direction and the unwinder of the second roll-to-roll process unwinds the electrode in the vertical direction.

[0013] In some exemplary embodiments, the roll pattern matching unit may be configured to match the roll pattern of the first roll-to-roll process with the roll pattern of the second roll-to-roll process when the rewinder of the first roll-to-roll process winds the electrode in the vertical direction and the unwinder of the second roll-to-roll process unwinds the electrode in the vertical direction are opposite to each other, while maintaining the channel arrangement order of the roll pattern of the first roll-to-roll process in the width direction.

[0014] In some exemplary embodiments, the roll pattern matching unit may be configured to match the roll pattern of the first roll-to-roll process with the roll pattern of the second roll-to-roll process by reversing the channel arrangement order of the roll pattern of the second roll-to-roll process when the rewinder of the first roll-to-roll process winds the electrode in the upper portion and the unwinder of the second roll-to-roll process unwinds the electrode in the upper portion.

[0015] In some exemplary embodiments, the roll pattern matching unit may be configured to match the roll pattern of the first roll-to-roll process with the roll pattern of the second roll-to-roll process by maintaining the channel arrangement order of the roll pattern of the second roll-to-roll process and reversing the top and back surfaces of the roll pattern of the second roll-to-roll process when the rewinder of the first roll-to-roll process winds the electrode in the upper portion and the unwinder of the second roll-to-roll process unwinds the electrode in the lower portion.

[0016] In some exemplary embodiments, the roll pattern matching unit may be configured to match the roll pattern of the first roll-to-roll process with the roll pattern of the second roll-to-roll process by maintaining the channel arrangement order of the roll pattern of the second roll-to-roll process and reversing the top and back surfaces of the roll pattern of the second roll-to-roll process when the rewinder of the first roll-to-roll process winds the electrode in the lower portion and the unwinder of the second roll-to-roll process unwinds the electrode in the upper portion.

[0017] In some exemplary embodiments, the roll pattern matching unit may be configured to match the roll pattern of the first roll-to-roll process with the roll pattern of the second roll-to-roll process by reversing the channel arrangement order of the roll pattern of the second roll-to-roll process when the rewinder of the first roll-to-roll process winds the electrode in the lower portion and the unwinder of the second roll-to-roll process unwinds the electrode in the lower portion.

[0018] In some exemplary embodiments, the roll pattern matching unit may be configured to map the start point of the roll pattern of the first roll-to-roll process to the end point of the roll pattern of the second roll-to-roll process.

[0019] In some exemplary embodiments, the roll pattern matching unit may be configured to map the end point of the roll pattern of the first roll-to-roll process to the start point of the roll pattern of the second roll-to-roll process.

[0020] Another aspect of this disclosure is a roll pattern creation system for a series of sequentially repeated roll-to-roll processes in which electrodes unwound from an unwinder are processed and then wound by a rewinder. The roll pattern creation system includes roll pattern creation means for creating a roll pattern for each process. The roll pattern is defined in a coordinate plane having two axes: a longitudinal axis of the electrode and a width axis of the electrode. The position of the electrode in each process is represented by coordinate values ​​in the coordinate plane. The roll pattern creation means is configured to create a first roll pattern for a first roll-to-roll process and a second roll pattern for a second roll-to-roll process, the first roll-to-roll process preceding the second roll-to-roll process. The roll pattern creation means includes information on the winding aspect of the first roll-to-roll process and the unwinding aspect of the second roll-to-roll process.

[0021] In some exemplary embodiments, the second roll-to-roll process can be performed immediately after the first roll-to-roll process.

[0022] In some exemplary embodiments, the roll pattern creation apparatus is configured to read the winding pattern of the first roll-to-roll process and the unwinding pattern of the second roll-to-roll process, wherein the roll pattern creation apparatus may be configured to match the top surface of the first roll pattern with the top surface of the second roll pattern when the winding pattern of the first roll-to-roll process and the unwinding pattern of the second roll-to-roll process are the same, and to reverse the width direction channel arrangement order of the second roll pattern based on the travel direction of the electrodes to match the channels of the first roll pattern.

[0023] In some exemplary embodiments, the roll pattern creation apparatus is configured to read the winding pattern of the first roll-to-roll process and the unwinding pattern of the second roll-to-roll process, wherein the roll pattern creation apparatus may be configured to match the top surface of the first roll pattern with the back surface of the second roll pattern when the winding pattern of the first roll-to-roll process and the unwinding pattern of the second roll-to-roll process are different from each other, without changing the arrangement order of the width direction channels of the second roll pattern based on the travel direction of the electrodes.

[0024] In some exemplary embodiments, the roll map creation apparatus may be configured to further create a roll map that integrates the first roll map and the second roll map.

[0042] (First Implementation)

[0043] Figure 1 It is a conceptual perspective view that schematically shows the state of an electrode after undergoing an electrode manufacturing process.

[0044] refer to Figure 1The coated electrode 1 is manufactured by coating an active material onto a current collector in a coating machine C to form a coated portion 1a. An uncoated portion 1b, without active material, can be marked with a reference point. In some exemplary embodiments, the active material can be coated on both the top and back surfaces of the electrode 1. The coated electrode 1 can be pressed by a pressure roller in a rolling process and can be cut along the longitudinal direction of the coated electrode 1 by a slitting machine in a slitting process.

[0045] Then, in the grooving process, the electrode tabs 2 can be formed by stamping using a press or similar method. In the grooving process, each unit electrode forms an electrode tab 2, allowing each unit electrode to be cut into a battery cell, or to be cut in subsequent processes. The width of the unit electrode corresponds to the spacing P processed by the press.

[0046] This electrode manufacturing process is performed 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 of the roll forming process. The electrode roll is wound on the rewinder of the roll forming process and completed as the electrode roll for 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, can be rewound onto the rewinder of the subsequent process to complete as the electrode roll for 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 is moved and wound in the rewinder (the so-called roll-to-roll process) is repeated sequentially.

[0047] Figure 2 This is a conceptual diagram illustrating a roll pattern created in an electrode manufacturing process according to an embodiment of the present disclosure.

[0048] As described above, electrodes are transported in roll-to-roll processes such as coating, rolling, and slitting. A roll diagram simulating this type of electrode transport is shown in bar form, where the longitudinal and width positions of the electrodes are represented by coordinates. In other words, the roll diagram is defined on a coordinate plane with two coordinate axes (longitudinal and width axes) of the electrodes, and each position of the electrode on the coordinate plane can be represented by coordinate values ​​on the plane. In such a roll diagram, information about defects, quality issues, electrode breakage, etc., occurring during the electrode manufacturing process is stored along with the coordinates, facilitating concise visualization of data related to quality or defects in the electrode manufacturing process.

[0049] refer to Figure 2Information about external defects such as pinhole defects f1 and line defects f2 is visualized and displayed at the coordinates of where the defects occur. Furthermore, a misalignment f3 between the coated and uncoated portions is shown. Other loading defects are also shown, as well as portions of the electrode discarded at the outermost edge.

[0050] Additionally, reference points K1, K2, and K3 can be marked on electrode 1 at predetermined intervals. When a fracture occurs in electrode 1 and a seam connecting member is connected, the electrode length is reduced to the fracture length. As mentioned above, points with external defects may 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 Coordinates that do not reflect electrode roll removal as described above and coordinates that do reflect electrode roll removal as described above are shown together in a single roll plot. The former is called absolute coordinates (x), and the latter is called relative coordinates (y). Figure 2 As 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.

[0051] Such roll diagrams can be created 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 during the roll-to-roll process, making the end of the roll diagram representing the electrode roll of the previous process the start of the roll diagram representing the electrode roll of the subsequent process. Furthermore, in the case of double-sided electrodes where the electrode active material is coated on both sides of the electrode, the electrode surface can be reversed; for example, the top electrode in the previous process becomes the back electrode in the subsequent process. In other words, depending on the winding direction of the electrode in the previous process and the unwinding direction of the electrode in the subsequent process, the start and end points of the electrode can be reversed, and the surface can be reversed. Since the roll diagram for each process is created based on these reversed electrodes, the coordinates of the roll diagram 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 portions in a series of roll-to-roll processes. The roll diagram for each process reflects these reversals and length changes, and therefore can have different coordinate values.

[0052] In the final stage of the electrode manufacturing process, after removing portions of the electrode that were removed in previous processes, only the remaining electrode (the retained electrode) remains. Since the battery is manufactured from the retained electrode, if a problem occurs in the finished or semi-finished battery, the cause of the problem can be traced by referring to the roll pattern of the final retained electrode. Furthermore, the problematic electrode portion can be traced back by referring to the roll patterns of each of the aforementioned processes. Therefore, roll patterns are a useful tool for quality and defect identification and quality tracking.

[0053] Figure 3 This is a conceptual diagram illustrating the relationship between two consecutive roll-to-roll processes P1 and P2 according to an embodiment of the present disclosure.

[0054] refer to Figure 3 The first roll-to-roll process P1, which is the preceding process, is followed by the second roll-to-roll process P2, which is the following process.

[0055] In the first roll-to-roll process P1, the electrode roll unwound from the first unwound unit UW1 is rewound in the first rewinder RW1 after undergoing a predetermined treatment. The electrode wound in the first rewinder RW1 is then supplied to the second rewinder RW2 for the second roll-to-roll process P2. Then, in the second roll-to-roll process P2, the electrode unwound from the second unwound unit UW2 is rewound in the second rewinder RW2 after undergoing a predetermined treatment.

[0056] However, in Figure 3 In the diagram, the direction in which the electrode is wound in the first rewinder RW1 is shown as upward winding, but in a specific process, it can be downward winding. Furthermore, in... Figure 3 In the diagram, the direction in which the electrode is unwound in the second unwinder UW2 is shown as upward unwinding, but in a particular process, it can be downward unwinding.

[0057] In such a specific process, the winding direction and the unwinding direction may not be consistent, depending on the needs of the preceding and following processes.

[0058] Figure 4 This is a schematic concept diagram illustrating a specific roll-to-roll process according to an embodiment of the present disclosure.

[0059] refer to Figure 4 Electrode E may have two or more channels. Although electrode E is shown herein as having four channels L1, L2, L3, L4, those skilled in the art will understand that electrode E may have two, three, five or more channels.

[0060] Electrode E may include an active material layer on either or both of its top and back surfaces. Electrode E includes a start point S and an end point T, whereby the start point S is the point at which electrode E begins to be processed for the roll-to-roll process, and the end point T is the point at which electrode E completes the processing for the roll-to-roll process. After processing for the roll-to-roll process, electrode E is wound into a roll, which in some embodiments may be wound using the above winding method, wherein the processed electrode E is positioned in the upper portion of the first rewinder 1113 above the central axis of the first rewinder 1113. The roll wound using the above winding method is hereinafter referred to as the first electrode roll R1.

[0061] In other embodiments, the electrode E to be processed can be wound using a winding method in which the electrode E is located in a lower portion below the central axis of the first rewinder 1113. The roll wound using the following winding method is hereinafter referred to as the second electrode roll R2.

[0062] In the case of the first electrode roll R1, the top surface of the electrode E forms the outer surface of the first electrode roll R1, and in the case of the second electrode roll R2, the back surface of the electrode E forms the outer surface of the second electrode roll R2.

[0063] Figure 5 This is a conceptual diagram showing the configuration (aspect) of the first electrode roll R1, which is wound in the upper part of the first roll-to-roll process P1, and mounted on the second unwinder 2111 in the second roll-to-roll process P2.

[0064] refer to Figure 5 After being wound in the first rewinder 1113, the first electrode roll R1 is provided to the second unwinder 2111 in the second roll-to-roll process P2 in a subsequent process. When the first electrode roll R1 is mounted on the second unwinder 2111, the electrode E to be processed can be unwound by the above unwinding method, in which the electrode E is located in the upper part (T11) of the second unwinder 2111 above the central axis of the second unwinder 2111.

[0065] In this case, the top surface of the first electrode roll R1 in the first roll-to-roll process P1 can be maintained in the second roll-to-roll process P2. However, the arrangement order of the channels in the second roll-to-roll process P2 of the first electrode roll R1 is reversed compared to the first roll-to-roll process P1. In other words, in the first roll-to-roll process P1, based on the forward direction of electrode E, the channels are arranged from left to right as L1, L2, L3, L4. On the other hand, in the second roll-to-roll process P2, based on the forward direction of electrode E, the channels are arranged from right to left as L1, L2, L3, L4.

[0066] When the first electrode roll R1 is mounted on the second unwinder 2111, the electrode E to be processed can be unwound by the lower unwinding method, in which the electrode E is located in the lower part below the central axis of the second unwinder 2111 to unwind the electrode E (T12).

[0067] In this case, the top surface in the first roll-to-roll process P1 of the first electrode roll R1 becomes the back surface in the second roll-to-roll process P2. However, the channel sequence in the second roll-to-roll process P2 of the first electrode roll R1 becomes the same as that in the first roll-to-roll process P1. In other words, based on the forward direction of the electrode E in both the first roll-to-roll process P1 and the second roll-to-roll process P2, the channels are arranged from left to right as L1, L2, L3, L4.

[0068] Figure 6 This is a conceptual diagram showing the configuration in which the second electrode roll R2, wound in the lower part in the first roll-to-roll process P1, is mounted on the second unwinder 2111 in the second roll-to-roll process P2.

[0069] refer to Figure 6 After being wound down in the first rewinder 1113, the second electrode roll R2 is provided to the second unwinder 2111 in the subsequent second roll-to-roll process P2. When the second electrode roll R2 is mounted on the second unwinder 2111, the electrode E can be unwound by the above unwinding method, in which the electrode E being processed is located in the upper part (T21) above the central axis of the second unwinder 2111.

[0070] In this case, the top surface in the first roll-to-roll process P1 of the second electrode roll R2 becomes the back surface in the second roll-to-roll process P2. However, the channel sequence in the second roll-to-roll process P2 of the second electrode roll R2 is the same as that in the first roll-to-roll process P1. In other words, based on the forward direction of electrode E in the first roll-to-roll process P1 and the second roll-to-roll process P2, the channels are arranged from the left as L1, L2, L3, L4.

[0071] When the second electrode roll R2 is mounted on the second unwinder 2111, the electrode E can be unwound by a lower unwinding method, in which the electrode E being processed is located in the lower part (T22) below the central axis of the second unwinder 2111.

[0072] In this case, the top surface of the second electrode roll R2 in the first roll-to-roll process P1 can be maintained in the second roll-to-roll process P2. However, the channel sequence of the second electrode roll R2 in the second roll-to-roll process P2 is reversed compared to that in the first roll-to-roll process P1. In other words, in the first roll-to-roll process P1, based on the forward direction of electrode E, the channels are arranged from the left as L1, L2, L3, L4. On the other hand, in the second roll-to-roll process P2, based on the forward direction of electrode E, the channels are arranged from the right as L1, L2, L3, L4.

[0073] As described above, depending on the direction of winding the electrode roll in the preceding roll-to-roll process and the direction of unwinding the electrode roll in the subsequent roll-to-roll process, the top and back surfaces of the electrodes may be switched, and furthermore, the arrangement order of the electrode channels in width may be changed. Therefore, taking into account these changes, the roll pattern created in the preceding roll-to-roll process and the roll pattern created in the subsequent roll-to-roll process should match each other.

[0074] Figure 7 This is a block diagram illustrating a roll drawing creation system 1 according to an embodiment of the present disclosure.

[0075] refer to Figure 7The roll pattern creation system 1 includes a first roll rewinding device 110 and a second roll rewinding device 210. The first roll rewinding process P1 (see reference) is performed on the first roll rewinding device 110. Figure 3 This can be combined with the second roll rewinding process P2 performed on the second roll rewinding device 210 (see reference). Figure 3 The processes are executed continuously. In particular, the first roll-to-roll process P1 can be executed before the second roll-to-roll process P2.

[0076] The first roll-to-roll device 110 may include a first unwinder 1111, a first rewinder 1113, a first rotary encoder 1121, a second rotary encoder 1125, a first measuring instrument 1130, and a first process programmable logic controller (PLC) 1143.

[0077] The first unwinder 1111 may be provided with an electrode roll to be processed in the first roll-to-roll process P1, and the first unwinder 1111 may be configured to unwind the electrode roll. The first rewinder 1113 may be configured to rewind the processed electrode E1 discharged from the first unwinder 1111. As mentioned above, the electrode roll wound in the first rewinder 1113 may be wound by either an upper winding method or a lower winding method.

[0078] The first rotary encoder 1121 can be configured to detect the degree to which electrode E1 has been unwound by the first unwounder 1111. The first rotary encoder 1121 can be configured to be contact or non-contact. In some exemplary embodiments, the first rotary encoder 1121 can be configured to sense the length of the electrode E1 unwound by the first unwounder 1111. In response, the first rotary encoder 1121 can be configured to generate an unwound amount signal (UWAS) representing the length of the electrode E1 that has been unwound, and send it to the first roll plot PLC 1171, which is described in more detail below. The first roll plot PLC 1171 can be configured to collect unwound amount data based on the received unwound amount signal (UWAS).

[0079] The second rotary encoder 1125 can be configured to detect the degree to which the electrode E1 has been wound by the first rewinder 1113. The second rotary encoder 1125 can be configured as a contact or non-contact type. In some exemplary embodiments, the second rotary encoder 1125 can be configured to sense the length of the electrode E1 wound by the first rewinder 1113. In response, the second rotary encoder 1125 can be configured to generate a winding amount signal (WAS) representing the length to which the electrode E1 has been wound, and send it to the first roll pattern PLC 1171, which is described in more detail below. The first roll pattern PLC 1171 can be configured to collect winding amount data based on the received winding amount signal (WAS).

[0080] The first measuring instrument 1130 can be configured to measure electrode E1 to collect measurement data (MD) of electrode E1 as it is transferred from the first unwound device 1111 to the first rewound device 1113. The first measuring instrument 1130 can measure electrode E1 using a scanning method. In some exemplary embodiments, the first measuring instrument 1130 can move along the width direction of electrode E1. In some exemplary embodiments, during a single scan of the first measuring instrument 1130, the first measuring instrument 1130 can move from one end of the width direction of electrode E1 to the other end of the width direction. When the first measuring instrument 1130 performs a scan in the width direction, electrode E1 can move in the longitudinal direction of the electrode via the first unwound device 1111 and the first rewound device 1113.

[0081] Measurement data (MD) may include test results represented numerically. For example, measurement data (MD) may include the coordinates and dimensions of the slotted portion on electrode E1. In some exemplary embodiments, 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 disposed on the coating material and the overlap width between the coating material and the insulating material), misalignment data between the coating channel on the upper surface of the electrode and the coating channel on the lower surface of the electrode, etc. Here, the loading amount represents the amount of coating material loaded per unit area of ​​electrode E1, which may be the area density of the coating material. Measurement data (MD) can be processed by a set method to determine the quality of the measured portion of the electrode.

[0082] The first measuring instrument 1130 may include a first sensing unit 1131 and a first processing unit 1133.

For example, the first 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 first 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 exemplary embodiments, the first 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 exemplary embodiments, the first measuring instrument 1130 may also include a pressure sensor, a temperature sensor, an ultrasonic sensor, a proximity sensor, a door status sensor, a motion tracking sensor, a humidity sensor, a visible and infrared sensor, a camera, etc.

[0083] The first roll-to-roll device 110 may also include an inspector configured to inspect the electrode E1 to collect inspection data. The inspection data may include determinations of quality and processing events for a portion of the electrode E1. For example, the inspection data may include data on the appearance of the electrode collected by an image-based inspection device (such as a vision machine), data on breaks and joints in the electrode, data on the portion of the electrode for which sampling inspection is performed, data on the portion of the electrode intended for scrapping and data on the scrapped portion of the electrode, data on the quality of the coating and insulating materials on the electrode, data on reference points indicating the position of the electrode, and data on defects (such as pinhole defects, pit defects, line defects, crack defects, side ring defects, island defects, fold defects, wrinkle defects, indentation defects, and dent defects). Reference points may be formed on the electrode at predetermined intervals, and the positions of other components on the electrode may be located based on these reference points. The inspector may be any of a color sensor, a joint sensor, a reference point sensor, and a vision machine.

[0084] The aforementioned measurement (MD) and inspection data can be time-series data. The measurement (MD) and inspection data can be ordered chronologically. Time ordering is a key characteristic of time-series data, where events are organized in the order in which they occur and arrive for processing. In other words, the measurement (MD) and inspection data can be stored based on the time points at which measurements and inspections are performed, and the measurement (MD) and inspection data can be time-related. Furthermore, the measurement (MD) and inspection data can be correlated with positions on electrodes identified based on reference points.

[0085] The first processing unit 1133 can be configured to collect the measurement signal MS sensed by the first sensing unit 1131 to generate measurement data (MD). The first processing unit 1133 can be connected to the first sensing unit 1131 via wired or wireless connection.

[0086] The first roll-to-roll PLC 1171 can operatively communicate with the first rotary encoder 1121 and the second rotary encoder 1125, the first measuring instrument 1130, and additional measuring instruments and inspectors via a wired or wireless data network. The data network can be unidirectional or bidirectional. The data network can be implemented using physical channels, Wi-Fi, Bluetooth, and / or other frequency bands via public and / or private networks. The first rotary encoder 1121 and the second rotary encoder 1125, the first measuring instrument 1130, and the additional measuring instruments and inspectors can be configured to collect data from equipment, work products, semi-finished products, and finished products within the first roll-to-roll assembly 110, or to generate signals for collecting data.

[0087] The first volume PLC 1171 can be configured to send coordinate data (CD) to a first processing unit 1133. The first processing unit 1133 can be configured to associate measurement data (MD) with the coordinate data (CD) to generate coordinate-dependent measurement data (CMD). Typically, the measurement data (MD) can be processed based on a trigger point. Examples of processing the measurement data (MD) may include storing the measurement data (MD), manipulating the measurement data (MD) (e.g., generating coordinate-dependent measurement data (CMD)), and sending the measurement data (MD).

[0088] As a non-limiting example, the trigger point for processing measurement data (MD) can be the completion of a scan. For example, the first 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 measurement data MD. In other examples, the trigger point can be the completion of multiple scans or the completion of a portion of a scan.

[0089] The first processing unit 1133 can be configured to send coordinate-dependent measurement data (CMD) to the first roll-up PLC 1171. The first roll-up PLC 1171 can be configured to send coordinate-dependent measurement data (CMD) to the first process PLC 1143.

[0090] Coordinate-dependent measurement data (CMD) sent to the first process PLC 1143 can be transmitted to the first server 150 via the first process PLC 1143 and the first device interface (EIF) 145. The first process PLC 1143 and the first EIF 145 can relay data communication including the measurement data (CMD) between the first server 150 and the first plotting PLC 1171. However, this is not a limitation; the first plotting PLC 1171 can be configured to send the coordinate-dependent measurement data (CMD) directly to the first server 150.

[0091] The first process PLC 1143 can be configured to control the operation of the first unwinder 1111 and the first rewinder 1113. The first process PLC 1143 can be configured to generate signals for operating and stopping the first unwinder 1111 and the first rewinder 1113.

[0092] In some exemplary embodiments, each of the first volume diagram PLC 1171 and the first process PLC 1143 may be part of a PLC (first PLC 1140).

[0093] To control the first roll-to-roll process, a communication line can be installed between the first process PLC 1143 and the first server 150 via the first EIF 145, connecting the first process PLC 1143 and the first server 150. Therefore, data transmission via the first process PLC 1143 can be performed by the first rotary encoder 1121 and the second rotary encoder 1125, and the first measuring instrument 1130 directly sends the unwinding quantity signal (UWAS), winding quantity signal (WAS), and measurement signal (MS) to the first server 150. Compared to the case where the first roll drawing PLC 1171 directly sends the 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.

[0094] The first EIF 145 may be a device for communication between a first process PLC 1143 in a manufacturing facility and a first server 150, which acts as an upper-level server.

[0095] In some exemplary embodiments, the first server 150 may include a first roll pattern creation unit configured to generate a first roll pattern. The first roll pattern may be process data of the electrode E1 on a plane simulating the movement of the electrode E1 between the first unwinder 1111 and the first rewinder 1113. In this case, the first server 150 may act as a roll pattern creation device.

[0096] In some exemplary embodiments, the first roll drawing PLC 1171 may include a first roll drawing creation unit configured to generate the first roll drawing. In this case, the first roll drawing PLC 1171 may act as a roll drawing creation device. The case where the first server 150 creates the first roll drawing will be described below. However, the first roll drawing PLC 1171 may also be configured to create the first roll drawing in the same, equivalent, or similar manner as the configuration associated with the first server 150 that creates the first roll drawing.

[0097] A first roll pattern can be generated in batch units formed by winding and cutting electrode E1. The first roll pattern may include data about batch specifications. Batch specifications may 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 the electrode processing.

[0098] According to an exemplary embodiment, the first server 150 may be a data processing system that supports various activities required for managing the manufacture of secondary batteries, such as work schedule 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 input, process, output, and communicate data required for performing the first roll-to-roll process.

[0099] The first server 150 can generate visualization commands (VCs) for visualizing the first volume diagram. The first server 150 can transmit the visualization commands (VCs) to the display device 160, and the display device 160 can visualize the first volume diagram to display the visualized first volume diagram.

[0100] In some exemplary embodiments, the first processing unit 1133 may be configured to transmit coordinate correlated measurement data (CMD) and / or coordinate data (CD) to a second server 180. According to an exemplary embodiment, the coordinate correlated measurement data (CMD) and coordinate data (CD) may be transmitted to the second server 180 via a first eIoT 170. The first eIoT 170 may be an apparatus for communication between the first processing unit 1133 and the second server 180.

[0101] In some exemplary embodiments, the second server 180 may be configured to store and process measurement data (MD) of the electrodes. The second server 180 can continuously monitor the processing of the electrodes based on the measurement data MD, thereby managing the processing quality of the electrodes. According to an exemplary embodiment, 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.

[0102] The third server 190 can be configured to store coordinate-dependent measurement data (CMD) sent from the first server 150. The third server 190 can also be configured to store measurement data (MD) sent from the second server 180. If 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-dependent measurement data (CMD), evaluation data (ED), and measurement data (MD). The third server 190 can be, for example, a data warehouse, and can store coordinate-dependent measurement data (CMD), evaluation data (ED), and measurement data (MD) for extended periods, such as based on product quality assurance periods.

The first processing unit 1133, the first volume diagram PLC 1171, the first process PLC 1143, the first EIF 145, the first server 150, the first eIoT 170, the second server 180, and the third server 190 may be implemented by, for example, a general-purpose computer or dedicated hardware (such as digital signal processing (DSP), field-programmable gate array (FPGA), and application-specific integrated circuit (ASIC)).

[0104] First server 150 and second server 180 can generate a first roll drawing and an intermediate roll drawing. Because first server 150 stores and processes a large amount of data for general manufacturing management, in addition to the first roll drawing, the first roll drawing stored on first server 150 may include processed and simplified coordinate-dependent measurement data (CMD) instead of raw measurement data (MD). Second server 180 can store raw measurement data (MD) for SPC operations. Second server 180 can send measurement data (MD) corresponding to a selected portion of the first roll drawing in response to a command from first server 150.

[0105] Intermediate volume plots may also include measurement data (MD) associated with the first volume plot; in other words, in addition to the first volume plot, intermediate volume plots may include measurement data (MD) as raw data. Measurement data (MD) may be associated with the first volume plot based on time values. Therefore, intermediate volume plots can provide additional insights into the quality of work products, process performance, overall equipment effectiveness (OEE) drilling down, anomaly detection, traceability, preventative maintenance, and predictive alerts.

[0106] The first server 150, the second server 180, and the third server 190 may include physical servers or cloud servers.

[0107] 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 case, metrics are tools for visualizing data. Metrics include time-series generated measurements and can be used to monitor applications and generate status alerts.

[0108] The first roll-to-roll device 110 can implement a plug-in architecture with an API for data acquisition to provide plug-and-play connectivity for the first measuring instrument 1130 and additional measuring instruments and inspectors. Therefore, resources at specific process steps and stations can be easily relocated to other processes and stations, or new resources can be easily introduced at each process step and station.

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), 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.

[0113] The first processing unit 1133 can be implemented, for example, by software configured to receive coordinate data (CD), generate coordinate-dependent measurement data (CMD), and send measurement data (MD), coordinate data (CD), and coordinate-dependent measurement data (CMD).

[0114] For example, the first volume PLC 1171 can be implemented by software configured to collect coordinate data (CD), receive coordinate related measurement data (CMD), and send coordinate data (CD) and coordinate related measurement data (CMD).

[0115] The first process PLC 1143 can be implemented by software, which is configured to generate control signals for controlling the first unwinder 1111, the first rewinder 1113 and the grooving machine 1115 based on the product ID and product recipe, receive coordinate data (CD) and coordinate related measurement data (CMD), and send coordinate data (CD) and coordinate related measurement data (CMD).

[0116] The first EIF 145 can be implemented by software used to relay the transmission of data and information between the first process PLC 1143 and the first server 150. More specifically, the first EIF 145 can be implemented by software configured to perform flow control, error control, synchronization, sequence control, addressing, multiplexing, routing, and formatting for communication between the first process PLC 1143 and the first server 150.

[0117] For example, the first server 150 can be implemented by software configured to transmit product ID and product recipe to the first process PLC 1143 and generate a first roll plot based on coordinate correlation measurement data (CMD).

Therefore, the fourth rotary encoder 2125 can be configured to generate a winding amount signal (WAS) representing the length of the electrode E2 wound, and send it to the second roll-map PLC 2171, which is described in more detail below. The second roll-map PLC 2171 can be configured to collect winding amount data based on the received winding amount signal (WAS).

While the second measuring instrument 2130 performs a scan in the width direction, electrode E2 can be moved by the second unwound device 2111 and the second rewound device 2113 in the longitudinal direction of the electrode.

[0127] Measurement data (MD) may include test results represented numerically. In some exemplary embodiments, 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 disposed on the coating material and the overlap width between the coating material and the insulating material), misalignment data between the coating channels on the upper surface of the electrode and the coating channels on the lower surface of the electrode, etc. Here, the loading amount indicates the amount of coating material loaded per unit area of ​​electrode E2, which may be the area density of the coating material.

[0130] The aforementioned measurement (MD) and inspection data can be time-series data. The measurement (MD) and inspection data can be ordered chronologically. Time ordering is a key characteristic of time-series data, where events are organized in the order in which they occur and arrive for processing. In other words, the measurement (MD) and inspection data can be stored based on the time points at which measurements and inspections are performed, and the measurement (MD) and inspection data can be time-related. Furthermore, the measurement (MD) and inspection data can be correlated with positions on electrodes identified based on reference points.

[0131] The second processing unit 2133 can be configured to collect the measurement signal MS sensed by the second sensing unit 2131 to generate measurement data (MD). The second processing unit 2133 can be connected to the second sensing unit 2131 via wired or wireless connection.

The third rotary encoder 2121 and the fourth rotary encoder 2125, the second measuring instrument 2130, and the additional measuring instruments and inspectors can be configured to collect data from equipment, work products, semi-finished products, and finished products within the second roll-to-roll device 210, or to generate signals for collecting data.

[0133] The second volume diagram PLC 2171 can be configured to send coordinate data (CD) to a second processing unit 2133. The second processing unit 2133 can be configured to associate measurement data (MD) with the coordinate data (CD) to generate coordinate-dependent measurement data (CMD). Typically, the measurement data (MD) can be processed based on trigger points. Examples of processing the measurement data (MD) may include storing the measurement data (MD), manipulating the measurement data (MD) (e.g., generating coordinate-dependent measurement data (CMD)), and sending the measurement data (MD).

[0134] As a non-limiting example, the trigger point for processing measurement data (MD) can be the completion of a scan. For example, the second sensing unit 2131 can scan the electrode in the width direction of the electrode, and for each scan, it can store, process, modulate, and transmit the measurement data MD. In other examples, the trigger point can be the completion of multiple scans, or the completion of a portion of a scan.

[0137] The second process PLC 2143 can be configured to control the operation of the second unwinder 2111 and the second rewinder 2113. The second process PLC 2143 can be configured to generate signals for operating and stopping the second unwinder 2111 and the second rewinder 2113.

[0138] In some exemplary embodiments, each of the second volume diagram PLC 2171 and the second process PLC 2143 may be part of a single PLC (second PLC 2140).

[0139] To control the second roll-to-roll process, a communication line can be installed between the second process PLC 2143 and the first server 150 via a second EIF 245, connecting the two. Therefore, data transmission via the second process PLC 2143 can be performed by the third rotary encoder 2121 and the fourth rotary encoder 2125, as well as the second measuring instrument 2130. These instruments directly transmit the unwinding signal (UWAS), the winding signal (WAS), and the measurement signal (MS) to the first server 150. Compared to the second roll-to-roll diagram PLC 2171 directly transmitting 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.

[0140] The second EIF 245 may be a device for communication between a second process PLC 2143 in a manufacturing facility and a first server 150, which acts as an upper-level server.

[0141] In some exemplary embodiments, the first server 150 may include a second roll pattern creation unit configured to generate a second roll pattern. The second roll pattern may be process data of electrode E2 on a plane simulating the movement of electrode E2 between the second unwinder 2111 and the second rewinder 2113. In this case, the first server 150 may act as a roll pattern creation device.

[0142] In some exemplary embodiments, the second roll drawing PLC 2171 may include a second roll drawing creation unit configured to generate a second roll drawing. In this case, the second roll drawing PLC 2171 may act as a roll drawing creation device. Hereinafter, the case where the first server 150 creates the second roll drawing will be described. However, the second roll drawing PLC 2171 may also be configured to create the second roll drawing in the same, equivalent, or similar manner as the configuration associated with the first server 150 that creates the second roll drawing.

[0143] The second volume diagram can be generated in batch units formed by winding and cutting electrode E2. The second volume diagram may include data about batch specifications. Batch specifications may 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 the electrode processing.

[0144] The first server 150 may be, for example, a manufacturing execution system (MES). The first server 150 may be configured to input, process, output, and communicate the data required for the second roll-to-roll process.

[0145] The first server 150 can generate visualization commands (VCs) for visualizing the first volume diagram. The first server 150 can transmit the visualization commands (VCs) to the display device 160, and the display device 160 can visualize the first volume diagram to display a visualized second volume diagram.

[0146] In some exemplary embodiments, the second processing unit 2133 may be configured to transmit coordinate correlated measurement data (CMD) and / or coordinate data (CD) to the second server 180. According to an exemplary embodiment, the coordinate correlated measurement data (CMD) and coordinate data (CD) may be transmitted to the second server 180 via a second eIoT 270. The second eIoT 270 may be an apparatus for communication between the second processing unit 2133 and the second server 180.

[0147] In some exemplary embodiments, the second server 180 may be configured to store and process measurement data (MD) of the electrodes. The second server 180 can continuously monitor the processing of the electrodes based on the measurement data MD, thereby managing the processing quality of the electrodes. According to an exemplary embodiment, 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.

[0148] The second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the second EIF 245, the first server 150, the second eIoT 270, the second server 180, and the third server 190 can be implemented as hardware, firmware, software, or combinations thereof. For example, the second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the EIF 145, the first server 150, the second eIoT 270, the second server 180, and the third server 190 may include computing devices such as workstation computers, desktop computers, laptop computers, tablet computers, etc. The second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the second EIF 245, the first server 150, the second eIoT 270, the second server 180, and the third server 190 may include any of the following: a simple controller, a complex processor (such as a microprocessor, CPU, GPU, etc.), a software-configurable processor, and dedicated hardware and firmware. The second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the second EIF 245, the first server 150, the second eIoT 270, the second server 180, and the third server may be implemented by, for example, a general-purpose computer or dedicated hardware (such as digital signal processing (DSP), field-programmable gate array (FPGA), and application-specific integrated circuit (ASIC)).

[0149] First server 150 and second server 180 can generate a second roll plot and an intermediate roll plot. Because first server 150 stores and processes a large amount of data for general manufacturing management, in addition to the second roll plot, the second roll plot stored on first server 150 can include processed and simplified coordinate-dependent measurement data (CMD) instead of raw measurement data (MD). Second server 180 can store raw measurement data (MD) for SPC operations. Second server 180 can send measurement data (MD) corresponding to selected portions of the second roll plot in response to commands from first server 150.

[0150] Intermediate volume plots can also include measurement data (MD) associated with the second volume plot. In other words, in addition to the second volume plot, intermediate volume plots can include measurement data (MD) as raw data. Measurement data (MD) can be associated with the second volume plot based on time values. Therefore, intermediate volume plots can provide additional insights into the quality of work products, process performance, overall equipment effectiveness (OEE) drilling down, anomaly detection, traceability, preventative maintenance, and predictive alerts.

[0151] The second roll-to-roll device 210 can implement a plug-in architecture with an API for data acquisition to provide plug-and-play connectivity between the second measuring instrument 2130 and additional measuring instruments and inspectors. Therefore, resources at specific process steps and stations can be easily relocated to other processes and stations, or new resources can be easily introduced at each process step and station.

[0152] The data network between the elements of the second roll-to-roll device 210 can include various types of communication channels, including one-way communication, two-way wired communication, and wireless communication. In one example, the data network can include industrial protocol networks such as OPC, Modbus, ProfiNet, etc. The communication channel can be dedicated pipe communication, such as Universal Serial Bus (USB), IEEE 802 (Ethernet), IEEE 1394 (FireWire), or other high-speed data communication standards.

[0153] In some examples, the second roll-to-roll device 210 may also include a manual input system that allows an operator to input manufacturing data. The second roll-to-roll device 210 may allow the operator to input data using input tools and computer-based manufacturing data input, such as by retrieving an Excel file.

[0154] According to some exemplary embodiments, the operation of the second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the second EIF 245, the first server 150, the second eIoT 270, 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), 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.

[0155] The second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the second EIF 245, the first server 150, the second eIoT 270, 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 described below. For example, the second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the second EIF 245, the first server 150, the second eIoT 270, the second server 180, and the third server 190 may be instantiated in memory.

[0156] The second processing unit 2133 can be implemented, for example, by software configured to receive coordinate data (CD), generate coordinate-dependent measurement data (CMD), and send measurement data (MD), coordinate data (CD), and coordinate-dependent measurement data (CMD).

[0157] For example, the second volume PLC 2171 can be implemented by software configured to collect coordinate data (CD), receive coordinate related measurement data (CMD), and send coordinate data (CD) and coordinate related measurement data (CMD).

[0158] The second process PLC 2143 can be implemented by software, which is configured to generate control signals for controlling the second unwinder 2111, the second rewinder 2113 and the software, receive coordinate data (CD) and coordinate related measurement data (CMD), and send coordinate data (CD) and coordinate related measurement data (CMD).

[0159] The second EIF 245 can be implemented by software used to relay the transmission of data and information between the second process PLC 2143 and the first server 150. More specifically, the second EIF 245 can be implemented by software configured to perform flow control, error control, synchronization, sequence control, addressing, multiplexing, routing, and formatting for communication between the second process PLC 2143 and the first server 150.

[0160] For example, the first server 150 can be implemented by software configured to transmit the product ID and product recipe to the second process PLC 2143 and generate a second roll plot based on coordinate correlated measurement data (CMD).

[0161] The second eIoT 270 may include software configured to collect, store, process, and transmit time-series data, coordinate data (CD), and / or coordinate-related measurement data (CMD) (such as measurement data (MD)).

[0162] The second server 180 may be implemented by software configured to store time-series data, coordinate data (CD), and / or coordinate-related measurement data (CMD) (such as measurement data (MD)), monitor the process based on the time-series data, coordinate data (CD), and / or coordinate-related measurement data (CMD), and send the time-series data, coordinate data (CD), and / or coordinate-related measurement data (CMD) in response to requests from the first server 150.

[0163] The third server 190 can be implemented by software configured to receive and store coordinate-dependent measurement data (CMD), evaluation data (ED), and / or measurement data (MD), and to retrieve coordinate-dependent measurement data (CMD), evaluation data (ED), and / or measurement data (MD).

[0164] However, this is only for ease of description, and the operation of the second processing unit 2133, the second volume diagram PLC 2171, the second process PLC 2143, the second EIF 245, the first server 150, the second eIoT 270, the second server 180 and the third server 190 described above can be caused by other devices that execute computing devices, distributed computing devices, processors, firmware, software, routines and commands, etc.

[0165] The first roll pattern created for an electrode roll in the first roll-to-roll process and the second roll pattern created for an electrode roll in the second roll-to-roll process need to be matched with each other. In other words, only by matching the corresponding positions of the first roll pattern and the second roll pattern created for an electrode roll with each other can it be tracked how a specific position of the electrode roll changes in the continuous process.

[0166] However, as mentioned above, the generation directions of the first roll pattern and the second roll pattern will be different from each other, depending on the shape in which one of the electrode rolls is wound in the rewinder of the previous process and the shape in which the electrode roll is unwound in the unwinder of the subsequent process. Therefore, in order to find the position on the second roll pattern corresponding to a specific position on the first roll pattern, a channel number and top / back face transformation are required according to predetermined rules.

[0167] Here, the term "winding configuration" or "unwinding configuration" refers to whether the electrode is located above or below the central axis of the winding rewinder or the unwinding rewinder. Specifically, if the electrode is located above the central axis of the winding rewinder, the winding configuration is called upper winding. Conversely, if the electrode is located below the central axis of the winding rewinder, the winding is called lower winding.

[0168] If the electrode is located in the upper part compared to the center axis of the unwinder, the unwinding configuration is called upper unwinding. Conversely, if the electrode is located in the lower part compared to the center axis of the unwinder, the unwinding configuration is called lower unwinding.

[0169] The first server 150 includes a roll pattern matching unit 155. The roll pattern matching unit 155 can match the physical electrodes represented by the roll pattern of the final process (e.g., the second roll pattern process P2) of a series of roll-to-roll processes (e.g., the first roll-to-roll process P1 and the second roll-to-roll process P2 executed thereafter) with the corresponding physical electrodes represented by the roll pattern of each process preceding the final process (e.g., the first roll-to-roll process P1).

[0170] In other words, the roll pattern matching unit 155 can be configured to match the first roll pattern M1 and the second roll pattern M2 with each other.

[0171] Figure 8 It is a schematic diagram conceptually illustrating the rules for matching the first volume diagram M1 and the second volume diagram M2 with each other.

[0172] refer to Figure 8 This illustrates the relationship between the first roll pattern M1 created in the first roll-to-roll process P1 and the second roll pattern M2 created in the second roll-to-roll process P2 for a specific electrode roll.

[0173] T11 shows the electrode E being wound up in the first roll-to-roll process P1 and unwound in the second roll-to-roll process P2. As shown, the top and back surfaces of electrode E remain unchanged in the first roll diagram M1 and the second roll diagram M2, but the order of channels L1, L2, L3, and L4 is reversed.

[0174] T12 illustrates the case where electrode E is wound in the upper portion during the first roll-to-roll process P1 and unwound in the lower portion during the second roll-to-roll process P2. As shown, the order of channels L1, L2, L3, and L4 in the first roll diagram M1 and the second roll diagram M2 remains unchanged, and the top and back surfaces of electrode E are interchanged.

[0175] T21 illustrates the case where electrode E is wound in the lower portion during the first roll-to-roll process P1 and unwound in the upper portion during the second roll-to-roll process P2. As shown, the order of channels L1, L2, L3, and L4 in the first roll diagram M1 and the second roll diagram M2 remains unchanged, and the top and back surfaces of electrode E are interchanged.

[0176] T22 illustrates the case where electrode E is wound in the lower part of the first roll-to-roll process P1 and unwound in the lower part of the second roll-to-roll process P2. As shown, the top and back surfaces of electrode E remain unchanged in the first roll diagram M1 and the second roll diagram M2, but the order of channels L1, L2, L3, and L4 is reversed.

[0177] like Figure 8 As shown, when the winding direction in the first roll-to-roll process P1 is the same as the unwinding direction in the second roll-to-roll process P2 (in other words, upper winding and upper unwinding, or lower winding and lower unwinding), the top and back surfaces of the electrodes are maintained, but the channel sequence is reversed based on the forward direction of the electrodes (T11, T22).

[0178] Furthermore, when the winding direction in the first roll-to-roll process P1 is different from the unwinding direction in the second roll-to-roll process P2 (in other words, upper winding and lower unwinding, or lower winding and upper unwinding), the channel sequence is maintained based on the forward direction of the electrodes, but the top and back surfaces of the electrodes are reversed (T12, T21).

[0179] exist Figure 8 In the process, the white surface is the surface that forms the top surface in the first roll-to-roll process, and the gray surface is the surface that forms the back surface in the first roll-to-roll process.

[0180] In either case, the starting point S1 in the first roll diagram M1 corresponds to the ending point T2 in the second roll diagram M2, and the ending point T1 in the first roll diagram M1 corresponds to the starting point S2 in the second roll diagram M2. This is because the subsequent process begins from the last part of the electrode roll that was wound in the previous process.

[0181] (Second Implementation)

[0182] In some exemplary embodiments, the winding pattern of the first roll-to-roll process relative to the preceding process and the unwinding pattern of the second roll-to-roll process relative to the following process can be stored in any one of the first server 150, the second server 180, and the third server 190. In some exemplary embodiments, the winding pattern of the first roll-to-roll process and the unwinding pattern of the second roll-to-roll process can be stored on the first server 150, which serves as the MES. In some exemplary embodiments, the first server 150 may further include a storage device capable of storing batch information including the winding direction and unwinding direction of the electrode rolls. In some exemplary embodiments, the storage device may be disposed within the roll pattern matching section 155.

[0183] In some exemplary embodiments, the first server 150 may be configured to read the winding configuration of a first roll-to-roll process P1 and the unwinding configuration of a second roll-to-roll process P2 stored in the first server 150, so as to match the first roll pattern M1 with the second roll pattern M2. After reading the winding configuration of the first roll-to-roll process P1 and the unwinding configuration of the second roll-to-roll process P2, the first server 150 can, according to... Figure 8 The rules shown match the corresponding positions.

[0184] In other words, if the winding pattern of the first roll-to-roll process P1 and the unwinding pattern of the second roll-to-roll process P2 are respectively top-wound and top-unwinded (i.e., case T11), then the first roll pattern M1 and the second roll pattern M2 are matched top-to-top and back-to-back, but the channel order is reversed. At this time, the start and end points of the first roll pattern M1 are matched with the end and start points of the second roll pattern M2, respectively.

[0185] When the winding configuration of the first roll-to-roll process P1 and the unwinding configuration of the second roll-to-roll process P2 are respectively down-winding and down-unwinding (in other words, case T22), the first roll pattern M1 and the second roll pattern M2 are matched top to top and back to back, but the channel order is reversed. At this time, the start and end points of the first roll pattern M1 are matched with the end and start points of the second roll pattern M2, respectively.

[0186] If the winding pattern of the first roll-to-roll process P1 and the unwinding pattern of the second roll-to-roll process P2 are respectively top winding and bottom unwinding (in other words, case T12), then the top surface of the first roll pattern M1 matches the back surface of the second roll pattern M2, and the back surface of the first roll pattern M1 matches the top surface of the second roll pattern M2, but the channel sequence is the same. At this time, the start and end points of the first roll pattern M1 match the end and start points of the second roll pattern M2, respectively.

[0187] If the winding pattern of the first roll-to-roll process P1 and the unwinding pattern of the second roll-to-roll process P2 are respectively bottom winding and top winding (in other words, case T21), then the top surface of the first roll pattern M1 matches the back surface of the second roll pattern M2, and the back surface of the first roll pattern M1 matches the top surface of the second roll pattern M2, but the channel sequence is the same. At this time, the start and end points of the first roll pattern M1 match the end and start points of the second roll pattern M2, respectively.

[0188] When the channel order in the first roll pattern M1 and the second roll pattern M2 is reversed, the first roll pattern M1 and the second roll pattern M2 can be matched such that the channels arranged from left to right based on the direction of electrode advance in the first roll-to-roll process are reversed to be positioned from right to left based on the direction of electrode advance in the second roll-to-roll process.

[0189] The coordinates in the longitudinal direction of the first roll M1 can be correlated with the coordinates in the longitudinal direction of the second roll M2, so that the start and end points of the first roll M1 are matched with the end and start points of the second roll M2, respectively. In some exemplary embodiments, the coordinates displayed in the uncoated portion 1b (see reference 1b) can be used. Figure 1 The reference point on the first volume of graph M1 and the second volume of graph M2 are matched with each other in the longitudinal direction.

[0190] As described above, if the winding directions of the rewinder in the first roll-to-roll process P1 and the unwinder in the second roll-to-roll process P2 are the same (refer to T11 and T22), then the first roll pattern M1 and the second roll pattern M2 can be matched such that the channel order is reversed, and the top surface of the first roll pattern M1 and the top surface of the second roll pattern M2 are matched, and the back surface of the first roll pattern M1 and the back surface of the second roll pattern M2 are matched.

[0191] When the winding directions of the rewinder in the first roll-to-roll process P1 and the unwinder in the second roll-to-roll process P2 are different from each other (refer to T12 and T21), the first roll pattern M1 and the second roll pattern M2 can be matched such that the top surface of the first roll pattern M1 matches the back surface of the second roll pattern M2 and the back surface of the first roll pattern M1 matches the top surface of the second roll pattern M2, but the channel order is the same.

[0192] In some exemplary embodiments, the first server 150 may be configured to display matching information on the display device 160 after matching the first scroll map M1 and the second scroll map M2. In some exemplary embodiments, the first server 150 may be configured to further create an overlay scroll map in which the first scroll map M1 and the second scroll map M2 are merged into one by matching the first scroll map and the second scroll map. In some exemplary embodiments, the first server 150 may be configured to display a combined scroll map by matching the first scroll map M1 and the second scroll map M2 on the display device 160.

[0193] In some exemplary embodiments, both the first roll drawing M1 and the second roll drawing M2 may also include information about the removed portions. During the process of performing the first roll-to-roll process P1 and the second roll-to-roll process P2, electrodes may be partially removed, for example, due to defects, and therefore, the removed portions of the electrodes may be shown in both the first roll drawing M1 and the second roll drawing M2. The portions that are not removed during the roll-to-roll process and remain as valid portions are referred to as the retained electrode portions, and the first roll drawing M1 and the second roll drawing M2 may include both the retained electrode portions and the removed portions.

[0194] Therefore, the removed portion of the first roll pattern M1 also exists as a removed portion in the corresponding portion of the second roll pattern M2. Additionally, the retained electrode portion of the second roll pattern M2 exists as a retained electrode portion in the corresponding portion of the first roll pattern M1. In some exemplary embodiments, the retained electrode portion of the first roll pattern M1 may exist as a removed portion in the corresponding portion of the second roll pattern M2, partially removed during the second roll-to-roll process P2.

[0195] As described above, although exemplary embodiments of the present disclosure have been described in detail, those skilled in the art to which this disclosure pertains will be able to implement the disclosure with various modifications without departing from the spirit and scope of the disclosure as defined in the appended claims. Therefore, further modifications to exemplary embodiments of the present disclosure will not depart from the technology of the present disclosure.
