Description

Technical Field

[0001] Cross-reference to related applications

[0002] This application claims priority and benefit to Korean Patent Application No. 10-2023-0189923, filed on December 22, 2023, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The implementation methods disclosed herein relate to simulation systems and methods of operating simulation systems. Background Technology

[0004] Recently, research and development on rechargeable batteries have been actively pursued. Here, a rechargeable battery is a battery capable of being charged and discharged, and can be interpreted as including all recent lithium-ion batteries such as conventional Ni / Cd and Ni / MH batteries. Among rechargeable batteries, lithium-ion batteries can achieve higher energy densities than conventional Ni / Cd and Ni / MH batteries, and can be manufactured in a compact and lightweight manner, thus offering high availability for powering mobile devices. Recently, with its application expanding to powering electric vehicles, lithium-ion batteries are gaining attention as a next-generation energy storage medium.

[0005] Because the manufacturing process of secondary batteries involves multiple specific assembly and inspection operations, new operators can learn the process with the help of experienced operators. However, when a newly introduced production line lacks skilled operators, or when language barriers exist for operator training in overseas factories, simulations that reproduce the battery manufacturing process in the same way as in the real world can be used for operator training. Activation processes such as the end-of-line (EOL) process can be performed to complete the manufacturing of cylindrical batteries. Measurement of electrical characteristics, visual inspection, and packaging of battery cells can be performed in the EOL process, but operators may require extensive field experience to become proficient in these tasks.

[0037] Figure 1 Examples of components constituting a training system according to some implementation methods are shown.

[0038] Reference Figure 1 The training system 100 may include a simulation system 120 and a simulation management server 130. However, this document is not limited to this, and some components may be omitted from the training system 100, or the training system 100 may include other general components.

[0039] Training system 100 can provide operator 110 with simulation training on battery manufacturing processes. According to an embodiment, the battery manufacturing processes may include processes for manufacturing cylindrical batteries, and these processes may include battery activation processes such as end-of-line (EOL) processes. Operator 110 can virtually experience the battery manufacturing processes through interaction with simulation system 120.

[0040] The simulation management server 130 can be configured to manage training content provided by the simulation system 120. The simulation management server 130 can record the results of executing the training content, derive statistical data based on the results, add or modify the substantive content of the training content based on the statistical data, and send the added or modified information to the simulation system 120. According to an embodiment, the simulation management server 130 can install content management software in the simulation system 120 and provide update information for the content management software.

[0041] Figure 2 Examples of components constituting a simulation system according to some implementation methods are shown.

[0042] Reference Figure 2The simulation system 120 may include an interface panel 121, a main simulator 122, and a display 123. However, this document is not limited to this, and some components may be omitted from the simulation system 120, or the simulation system 120 may include other general components.

[0043] According to the implementation, in the simulation system 120, the interface panel 121, the main emulator 122, and the display 123 can be electrically connected via device-to-device communication methods such as bus, general purpose input / output (GPIO), serial peripheral interface (SPI), mobile industrial processor interface (MIPI), etc.

[0044] Interface panel 121 can provide interface functionality between operator 110 and simulation system 120. According to an embodiment, interface panel 121 may include a human-machine interface (HMI) type panel. Interface panel 121 can receive manipulation input from operator 110 for operating simulation system 120 via input devices such as touch input, button input, mouse input, etc., and display a graphical interface such as a screen to help select manipulation input.

[0045] The main simulator 122 can be configured to perform simulations of battery manufacturing processes. The main simulator 122 can interact with operator 110 to perform the simulation. For example, the main simulator 122 can receive touch or drag input from operator 110, correspondingly changing the progress status of the EOL (End-of-Life) process, and displaying the changed progress status to operator 110. The main simulator 122 may include a processor and memory for executing simulation software.

[0046] The processor of the main emulator 122 may have a structure for executing commands that implement the operations of the main emulator 122. The processor may be implemented as an array of multiple logic gates or a general-purpose microprocessor for processing various computations, and the processor may be configured as a single processor or multiple processors. For example, the processor may be implemented as at least one of a microprocessor, CPU, GPU, and AP.

[0047] Memory and / or storage devices can be configured to temporarily store data or commands and can be configured separately from or integrated with a processor. A processor can perform various types of computations by executing commands stored in the memory and / or storage devices. Memory and / or storage devices can store various types of data, commands, software, mobile applications, computer programs, etc. For example, memory and / or storage devices can be implemented as non-volatile devices such as read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrical EPROM (EPROM), flash memory, programmable random access memory (PRAM), magnetoresistive RAM (MRAM), resistive RAM (RRAM), or ferroelectric RAM (FRAM), or volatile devices such as dynamic RAM (DRAM), static RAM (SRAM), synchronous dynamic RAM (SDRAM), or phase-change RAM (PRAM), and memory and / or storage devices can be implemented in the form of hard disk drives (HDDs), solid-state drives (SSDs), secure digital drives (SDs), micro SDs, or combinations thereof.

[0048] Display 123 may include a display device for providing various types of visual information to operator 110. Display 123 may display images of simulations performed on main emulator 122. For example, when an EOL process is performed in main emulator 122, visually recognizable external images may be displayed on main emulator 122, and images of invisible areas that cannot be recognized may be displayed on display 123.

[0049] Interface panel 121 can be configured to receive manipulation input from operator 110. Operator 110 can generate manipulation input through touch input, button input, mouse input, etc. Manipulation input can be used to drive the main simulator 122, select items, adjust process conditions, etc. According to the implementation, interface panel 121 can be manipulated in the same way as the control panel of the equipment used in an actual production line.

[0050] The master simulator 122 can be configured to load and reproduce training content for the end-of-life (EOL) process of manufacturing cylindrical batteries based on manipulation input. For example, the training content can be guided by manipulation input, and the training content may include a training simulation that reconstructs the EOL process in the same manner as in reality. According to an embodiment, the EOL process reproduced by the training content may be an activation process for completing the manufacturing of cylindrical batteries.

[0051] The main simulator 122 can be configured to provide training content to the operator 110 through interaction with the operator 110. For example, the operator 110 can indirectly experience the EOL process through the training content. According to an embodiment, the operator 110 can apply inputs such as touch and drag to the main simulator 122, and thus the main simulator 122 can provide the operator 110 with training content on processes such as measuring the internal resistance (IR) and / or open circuit voltage (OCV) of cylindrical batteries, inspecting the appearance of cylindrical batteries for defect screening, and packaging cylindrical batteries.

[0052] According to the implementation, the input to the equipment control panel to be applied to the actual production line can be implemented as the input to the interface panel 121, and the operation of the operator 110 that needs to be performed directly in the actual production line can be implemented through the input of the main simulator 122.

[0053] The display 123 can be configured to display detailed images of the detailed process according to the EOL process. For example, the display 123 can display detailed images of the state of the operator 110 inputting packaging materials, the operation process of the packaging equipment according to the state of the input of packaging materials, the shape of the packaging result, etc.

[0054] According to the implementation, the detailed process may include a first step of measuring the IR and OCV of the cylindrical battery, a second step of inspecting the appearance of the cylindrical battery to screen good and defective products, and a third step of packaging the cylindrical battery with packaging materials. Training content provided by the simulation system 120 can be configured to train operator 110 on the detailed process of the EOL (Exit-Order) procedure. The manufacturing process can be completed through the first, second, and third steps, and the cylindrical battery can be transported.

[0055] According to the implementation method, the training content may include guidance content for detailed procedures, virtual operation content for detailed procedures, condition adjustment content for process conditions of detailed procedures, and proficiency test content for detailed procedures. The guidance content can provide operator 110 with information such as work knowledge, manuals, and equipment operation methods required to perform the detailed procedures of the EOL (Extended Operating Level) procedure. The virtual operation content can virtually provide the work to be performed by operator 110 in an actual production line. The condition adjustment content allows operator 110 to adjust the process conditions of the detailed procedures of the EOL procedure and provides operator 110 with information on how the work results change due to the adjusted process conditions. The proficiency test content can test whether operator 110 is ready to perform the detailed procedures of the EOL procedure in an actual production line.

[0056] According to an implementation, the virtual operation content for the second process may include a false defect screening process for cylindrical cells that were classified as good products in the first process but are actually defective. In the first process, the IR and OCV of the cylindrical cells can be measured. Based on the values ​​of IR and OCV, it can be determined whether the cylindrical cells are defective. However, even when a cylindrical cell is determined to be good, a false defect may actually occur where the cylindrical cell appears to be a defective product. Operator 110 performs this visual inspection on an actual EOL line, and false defect screening content can be provided for virtual training in visual inspection.

[0057] According to an implementation, the condition adjustment content for the first process may include parameter adjustment content, which adjusts the parameters of the first process to adjust the ratio of cylindrical batteries that are actually defective but classified as good and the ratio of cylindrical batteries that are actually good but classified as defective. For example, the first process can be performed using an IR / OCV device for measuring the IR and OCV of cylindrical batteries. The IR / OCV device may have various process parameters such as the measurement frequency. Operator 110 can change the process parameters of the IR / OCV device through the parameter adjustment content and confirm the estimated values ​​of the ratio of cylindrical batteries that are actually defective but classified as good and the ratio of cylindrical batteries that are actually good but classified as defective. In this way, operator 110 can be trained to change the process parameters of the IR / OCV device through the parameter adjustment content.

[0058] According to the implementation, the virtual operation content for the third process may include content allowing operator 110 to add packaging materials for packaging cylindrical batteries, content indicating the addition state of the packaging materials added by operator 110, and content indicating the shape of the packaging result of the cylindrical batteries to be packaged according to the addition state. For example, packaging materials may include inner boxes, desiccants, anti-collision trays, packaging tape, outer boxes, ink, labels, etc. When operator 110 does not add packaging materials in the proper position, direction, and sequence, the operation of the equipment for packaging cylindrical battery cells with packaging materials may not be performed accurately, which may lead to packaging defects. In order to train operator 110 to add packaging materials to prevent such packaging defects from occurring, it can be shown how to form a packaging result according to the addition state of the packaging materials.

[0059] Figure 3 The structure of a simulation system according to some implementation methods is illustrated.

[0060] Reference Figure 3In the simulation system 120, the interface panel 121 can be located on the left side of the main simulator 122, and the display 123 can be located on the right side of the main simulator 122. However, this document is not limited to this, and different layout structures can be applied according to the body structure or movement of the operator 110.

[0061] Operator 110 can generate control inputs for manipulating the virtual device of the main simulator 122 on the interface panel 121 located on the left side of the main simulator 122, train the simulation content by touching and dragging inputs on the main simulator 122 located in the center, and confirm detailed images of the EOL process on the display 123 located on the right side.

[0062] Figure 4 The detailed steps of the end-of-line (EOL) process according to some implementation methods are illustrated.

[0063] Reference Figure 4 The detailed steps of EOL process 400 may include IR / OCV 410, visual inspection 420, and material packaging 430. However, this document is not limited to this, and various other detailed steps for activating cylindrical cells through EOL process 400 may also be considered.

[0064] IR / OCV 410 can be a process used to measure the IR and OCV of cylindrical battery cells. In an actual production line, IR / OCV 410 can be performed by an IR / OCV device, and the measurement parameters of the IR / OCV device can be adjusted. The IR / OCV device can be virtually implemented in the training content of the simulation system 120, and the operator 110 can be trained on IR / OCV 410 using a virtual 3D IR / OCV device.

[0065] Visual inspection 420 can be a process of inspecting cylindrical cells for appearance defects diagnosed as defective cells in terms of IR and / or OCV by IR / OCV 410. For example, even when a cylindrical cell has appropriate IR and OCV values, it can be determined that a cylindrical cell with cracks, impurities, dents, etc., in appearance is a defective cell with an accident risk. To train on various appearance defect scenarios, visual inspection 420 can be trained using simulation system 120.

[0066] Material packaging 430 can be a process for packaging cylindrical battery cells that have undergone visual inspection 420 into finished products. Cylindrical batteries can be packaged with packaging materials. In an actual production line, operator 110 can position and orient the packaging materials appropriately, and packaging equipment can perform the task of packaging cylindrical batteries with the packaging materials. However, when packaging materials are positioned, inappropriately, or in an inappropriate order or orientation, defective packaging results may occur, and to prevent this, operator 110 can learn material packaging 430 through simulation system 120.

[0067] The EOL (End-of-Life) process 400 provided to operator 110 via simulation system 120 can also include training on countermeasures in the event of equipment malfunctions. For example, equipment malfunctions may occur in an actual production line when there is a shortage of packaging materials or an emergency equipment stoppage, and operator 110 needs to identify the cause of the equipment stoppage and restart the equipment. To train for this, simulation system 120 can provide various scenarios of equipment malfunctions and stoppages. For example, operator 110 can learn about resupplying packaging materials, resolving safety issues, and restarting equipment through error countermeasure content.

[0068] Figure 5 Examples of training content provided by a simulation system according to some implementation methods are shown.

[0069] Reference Figure 5 Training content 500 may include process / equipment guidelines 510, operation preparation and start-up 520, material input 530, and quality inspection and rework 540.

[0070] The process / equipment guide 510 may include equipment operation manuals, operating methods, etc., for the IR / OCV equipment 511, the visual inspector 512, and the transport packaging machine 513. According to an embodiment, the visual inspection of the EOL process may be performed by a visual inspector, rather than directly by the operator 110. Alternatively, the visual inspection may be performed by both the operator 110 and the visual inspector.

[0071] Operational preparation and commencement 520 may include equipment inspection 521, production commencement 522, and LOT change 523. Material input 530 may include inner box input 531, ink replacement 532, polypropylene (PP) pallet input 533, desiccant input 534, outer box input 535, tape replacement 536, label replacement 537, etc. Quality inspection and rework 540 may include graded operations 541, rework 542, and comprehensive rework 543, etc.

[0072] Figure 6 The operation of a simulation system according to some implementation methods is illustrated.

[0073] Reference Figure 6 The operation method 600 of the simulation system may include operations 610 to 640. However, this document is not limited to this, and some operations may be omitted or general operations may be added, and the operations of the operation method 600 of the simulation system may be performed in a different order than that shown.

[0074] The operation method 600 of the simulation system may include operations performed by the simulation system 120 in a time sequence. Therefore, even though the following content is omitted, the above-described content for the simulation system 120 can be applied to the operation method 600 in the same manner.

[0075] Operations 610 to 640 of the simulation system's operation method 600 can be executed by the interface panel 121, the main simulator 122, and the display 123 of the simulation system 120.

[0076] In operation 610, the simulation system 120 can receive manipulation input from the operator.

[0077] In operation 620, simulation system 120 can load and reproduce training content for the EOL process of manufacturing cylindrical batteries based on manipulation input through the main simulator.

[0078] In operation 630, simulation system 120 can provide training content to the operator via the main simulator through interaction with the operator.

[0079] In operation 640, the simulation system 120 can display the detailed process of the EOL process on a monitor.

[0080] According to an implementation, the operation method 600 of the simulation system can be implemented as a computer program stored in a computer-readable storage medium. That is, the computer program may include commands for implementing the operation method 600 of the simulation system, and the commands of the program may be stored in a computer-readable storage medium. The computer program may include a mobile application.

[0081] According to embodiments, computer-readable recording media may include magnetic media such as hard disks, floppy disks, and magnetic tapes; optical media such as CD-ROMs and DVDs; magneto-optical media such as optical-magnetic floppy disks; and hardware devices specifically configured to store and execute program commands, such as ROMs, RAMs, and flash memory.
