[0003] Technology field

[0004] The embodiments disclosed in this document relate to a simulation system and a method of operating the simulation system.

[0005] Recently, active research and development has been conducted on secondary batteries. The term "secondary battery" refers to a rechargeable battery, encompassing both conventional Ni / Cd and Ni / MH batteries, as well as recent lithium-ion batteries. Among secondary batteries, lithium-ion batteries can boast higher energy densities than conventional Ni / Cd and Ni / MH batteries. They can be manufactured in small and lightweight designs, making them highly versatile power sources for mobile devices. Recently, their use has expanded to include power sources for electric vehicles, attracting attention as a next-generation energy storage medium.

[0006] Because the secondary battery manufacturing process involves numerous detailed assembly steps and inspection stages, new workers can learn the manufacturing process with the assistance of experienced workers. However, if a newly introduced process line lacks skilled workers or language barriers exist for worker training at an overseas factory, simulations that replicate the battery manufacturing process can be utilized for worker training. Activation processes, such as the end-of-line (EOL) process, may be performed to complete the manufacturing of cylindrical batteries. These processes may include electrical characteristic measurements, visual inspection, and battery cell packaging, but extensive on-site experience may be required for workers to become proficient in these processes.

[0036] Referring to FIG. 1, the training system (100) may include a simulation system (120) and a simulation management server (130). However, the present invention is not limited thereto, and some components may be omitted from the training system (100), or other general-purpose components may be further included in the training system (100).

[0037] The training system (100) can provide a worker (110) with simulation training regarding a battery manufacturing process. In an embodiment, the battery manufacturing process may include a cylindrical battery manufacturing process, and the cylindrical battery manufacturing process may include a battery activation process, such as an end-of-line (EOL) process. The worker (110) can virtually experience the battery manufacturing process through interaction with the simulation system (120).

[0038] The simulation management server (130) may be configured to manage training content provided by the simulation system (120). The simulation management server (130) may record the performance results of the training content, derive statistical data based thereon, add or change the content of the training content based on the statistical data, and transmit the added or changed information to the simulation system (120). According to an embodiment, the simulation management server (130) may install content management software in the simulation system (120) and provide update information of the content management software.

[0039] FIG. 2 may illustrate elements that constitute a simulation system according to some embodiments.

[0040] Referring to FIG. 2, the simulation system (120) may include an interface panel (121), a main simulator (122), and a display (123). However, the present invention is not limited thereto, and some components may be omitted from the simulation system (120), or other general-purpose components may be further included in the simulation system (120).

[0041] According to an embodiment, in the simulation system (120), the interface panel (121), the main simulator (122), and the display (123) can be electrically connected to each other through a device-to-device communication method such as a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), MIPI (mobile industry processor interface), etc.

[0042] The interface panel (121) can provide an interface function between the operator (110) and the simulation system (120). According to an embodiment, the interface panel (121) can include a panel in the form of an HMI (Human Machine Interface). The interface panel (121) can receive an operation input for operating the simulation system (120) from the operator (110) in the form of an input device such as a touch input, a button input, or a mouse, and can display a graphic interface such as a screen that assists in selecting the operation input.

[0043] The main simulator (122) may be configured to run a simulation of a battery manufacturing process. The main simulator (122) may interact with the operator (110) to facilitate the simulation. For example, the main simulator (122) may receive touch or drag inputs from the operator (110), change the progress status of the EOL process accordingly, and display the changed progress status to the operator (110). The main simulator (122) may include a processor and memory for executing simulation software.

[0044] The processor of the main simulator (122) may have a structure for executing instructions that implement the operations of the main simulator (122). The processor may be implemented as an array of multiple logic gates for processing various operations or as a general-purpose microprocessor, and may be composed of a single processor or multiple processors. For example, the processor may be implemented in the form of at least one of a microprocessor, a CPU, a GPU, and an AP.

[0045] Memory and / or storage may be configured to temporarily store data or instructions, and may be configured separately from or integral with the processor. The processor may execute instructions stored in the memory / storage to perform various operations. The memory / storage may store various data, instructions, software, mobile applications, computer programs, etc. For example, the memory / storage may be implemented as a non-volatile device such as ROM, PROM, EPROM, EEPROM, flash memory, PRAM, MRAM, RRAM, FRAM, etc., or a volatile device such as DRAM, SRAM, SDRAM, PRAM, etc., and may be implemented in the form of an HDD, SSD, SD, Micro-SD, etc., or a combination thereof.

[0046] The display (123) may include a display device that provides various visual information to the operator (110). The display (123) may display images of a simulation being executed in the main simulator (122). For example, when an EOL process is reproduced in the main simulator (122), external images recognizable to the naked eye may be displayed in the main simulator (122), and images of non-visible areas that cannot be recognized may be displayed in the display (123).

[0047] The interface panel (121) may be configured to receive manipulation input from a worker (110). The worker (110) may generate manipulation input through touch input, button input, mouse input, etc. The manipulation input may be utilized for driving the main simulator (122), selecting items, adjusting process conditions, etc. According to an embodiment, the interface panel (121) may be operated in the same manner as a facility manipulation panel used in an actual manufacturing line.

[0048] The main simulator (122) may be configured to load training content that reproduces the EOL process for manufacturing a cylindrical battery based on a manipulation input. For example, the training content may be booted through a manipulation input, and the training content may include a training simulation that realistically reconstructs the EOL process. In an embodiment, the EOL process reproduced by the training content may be an activation process for completing the manufacturing of a cylindrical battery.

[0049] The main simulator (122) may be configured to provide training content to the worker (110) through interaction with the worker (110). For example, the worker (110) may indirectly experience the tasks of the EOL process through the training content. According to an embodiment, the worker (110) may apply inputs such as touch or drag to the main simulator (122), and accordingly, training content for a process of measuring the internal resistance (IR) and / or open circuit voltage (OCV) of a cylindrical battery, a process of inspecting the appearance of a cylindrical battery to sort out defective products, a process of packaging a cylindrical battery, etc. may be provided to the worker (110).

[0050] According to an embodiment, inputs to be applied to the equipment operation panel in an actual manufacturing line can be implemented as inputs to the interface panel (121), and actions to be performed directly by the worker (110) through his / her own body in an actual manufacturing line can be implemented as inputs to the main simulator (122).

[0051] The display (123) may be configured to display detailed images according to the detailed processes of the EOL process. For example, the display (123) may display, as detailed images, the status of the worker (110) inputting packaging materials, the operation process of the packaging equipment according to the status of inputting packaging materials, the shape of the packaging result, etc.

[0052] In an embodiment, the detailed processes may include a first process for measuring the internal resistance (IR) and open circuit voltage (OCV) of the cylindrical battery, a second process for inspecting the appearance of the cylindrical battery to sort out good and defective products, and a third process for packaging the cylindrical battery using packaging materials. The training content provided by the simulation system (120) may be configured to train the worker (110) on the detailed processes of the EOL process. The manufacturing process may be completed through the first process, the second process, and the third process, and the cylindrical battery may be shipped.

[0053] According to an embodiment, the training content may include guide content for detailed processes, virtual operation content for detailed processes, condition adjustment content for process conditions of detailed processes, and proficiency test content for detailed processes. The guide content may provide the worker (110) with information on work knowledge, manuals, equipment operation methods, etc. required to perform detailed processes of the EOL process. The virtual operation content may virtually provide the worker (110) with tasks to be performed on an actual process line. The condition adjustment content may allow the worker (110) to adjust process conditions of detailed processes of the EOL process and may provide the worker (110) with information on how the work results change due to the adjusted process conditions. The proficiency test content may test whether the worker (110) is ready to perform detailed processes of the EOL process on an actual process line.

[0054] According to an embodiment, the virtual operation content for the second process may include pseudo-defect sorting content for sorting out cylindrical cells that were classified as good in the first process but are actually defective. Through the first process, the internal resistance (IR) and open circuit voltage (OCV) of the cylindrical battery may be measured. Based on the values ​​of the internal resistance (IR) and open circuit voltage (OCV), it may be determined whether the cylindrical battery is defective. However, even if the cylindrical battery is determined to be good, a pseudo-defect, which corresponds to a defect in the cylindrical battery in reality, may occur. The operator (110) performs such an external inspection on an actual EOL line, and the pseudo-defect sorting content may be provided for virtual training.

[0055] In an embodiment, the condition adjustment content for the first process may include parameter adjustment content that adjusts parameters of the first process to adjust the ratio of actually defective products that are classified as good products and the ratio of actually good products that are classified as defective products. For example, the first process may be performed using an IR / OCV device that measures the internal resistance (IR) and open circuit voltage (OCV) of a cylindrical battery. The IR / OCV device may have various process parameters, such as a measurement frequency. The operator (110) may change the process parameters of the IR / OCV device through the parameter adjustment content, and may check estimates of the ratio of defective products that are incorrectly classified as good products and the ratio of good products that are incorrectly classified as defective products before and after the parameter change. In this manner, the operator (110) may be trained to change the process parameters of the IR / OCV device through the parameter adjustment content.

[0056] According to an embodiment, the virtual operation content for the third process may include content that causes the worker (110) to input packaging materials for packaging a cylindrical battery, content that displays the input status of the packaging materials input by the worker (110), and content that displays the form of the packaging result of the cylindrical battery to be packaged according to the input status. For example, the packaging materials may include an in-box, a desiccant, a collision prevention tray, packaging tape, an out-box, ink, a label, etc. If the worker (110) does not input the packaging materials in the appropriate position, direction, and order, the operation of the equipment for packaging the cylindrical cell with the packaging materials may not be performed accurately, which may result in packaging defects. To prevent the occurrence of such packaging defects, and to train the worker (110) in inputting packaging materials, how the packaging result is formed according to the input status of the packaging materials may be displayed.

[0057] Figure 3 may illustrate the structure of a simulation system according to some embodiments.

[0058] Referring to FIG. 3, in the simulation system (120), an interface panel (121) may be placed on the left side of the main simulator (122), and a display (123) may be placed on the right side of the main simulator (122). However, this is not limited thereto, and a different arrangement structure may be applied depending on the physical structure or movement path of the worker (110).

[0059] The worker (110) can create operation inputs for operating virtual facilities of the main simulator (122) in the interface panel (121) on the left, train simulation contents through touch and drag inputs on the main simulator (122) in the center, and check detailed images of the EOL process through the display (123) on the right.

[0060] FIG. 4 may illustrate detailed processes of an EOL process according to some embodiments.

[0061] Referring to FIG. 4, detailed processes of the EOL process (400) may include IR / OCV (410), appearance inspection (420), and material packaging (430). However, the present invention is not limited thereto, and various other detailed processes for activating a cylindrical battery through the EOL process (400) may be additionally considered.

[0062] IR / OCV (410) may be a process for measuring the internal resistance (IR) and open circuit voltage (OCV) of a cylindrical cell. In an actual process line, IR / OCV (410) may be performed by an IR / OCV facility, and the measurement parameters of the IR / OCV facility may be adjusted. In the training content of the simulation system (120), the IR / OCV facility may be virtually implemented, and the operator (110) may train IR / OCV (410) through the virtual 3D IR / OCV facility.

[0063] The appearance inspection (420) may be a process for inspecting the appearance of a cylindrical cell that has been diagnosed as defective in terms of internal resistance (IR) and / or open circuit voltage (OCV) through IR / OCV (410). For example, even if the cylindrical cell has appropriate internal resistance (IR) and open circuit voltage (OCV) values, a cylindrical cell that has cracks, impurities, dents, etc. on its appearance may be judged as a defective cell with a risk of accident. To train various cases of appearance defects, the appearance inspection (420) may be trained through a simulation system (120).

[0064] Material packaging (430) may refer to a process for packaging cylindrical cells that have undergone an external inspection (420) into finished products. Cylindrical cells may be packaged using packaging materials. In an actual process line, the packaging materials may be placed in appropriate locations and directions by a worker (110), and the packaging equipment may perform the task of packaging the cylindrical cells using the packaging materials. However, if the packaging materials are not placed in appropriate locations, order, or directions, defective packaging results may be formed. To prevent this, the worker (110) may be trained in material packaging (430) using a simulation system (120).

[0065] The EOL process (400) provided to the operator (110) via the simulation system (120) may further include training on how to respond when an equipment error occurs. For example, if there is a shortage of packaging materials in an actual process line or an emergency equipment shutdown occurs, an equipment error may occur, and the operator (110) must identify the cause of the equipment shutdown and restart the equipment. To train for this, various equipment error and shutdown cases in various scenarios may be provided via the simulation system (120). For example, the operator (110) may learn how to resupply packaging materials, restart equipment after resolving safety issues, etc. through error response content.

[0066] FIG. 5 may illustrate training content provided by a simulation system according to some embodiments.

[0067] Referring to FIG. 5, training content (500) may include process / equipment guide (510), operation preparation and start-up (520), material input (530), and quality check and rework (540).

[0068] The process / equipment guide (510) may include equipment operation manuals, operating methods, etc. for the IR / OCV equipment (511), the appearance inspector (512), and the shipping packaging machine (513). According to an embodiment, the appearance inspection of the EOL process may be performed by the appearance inspector instead of directly by the operator (110). Alternatively, the appearance inspection may be performed by both the operator (110) and the appearance inspector.

[0069] Operation preparation and start (520) may include equipment inspection (521), production start (522), and lot change (523). Material input (530) may include in-box input (531), ink replacement (532), polypropylene (PP) tray input (533), desiccant input (534), out-box input (535), tape replacement (536), and label replacement (537). Quality check and rework (540) may include grading (541), rework (542), and integrated rework (543).

[0070] FIG. 6 may illustrate steps that constitute a method of operating a simulation system according to some embodiments.

[0071] Referring to FIG. 6, the operation method (600) of the simulation system may include steps (610) to (640). However, the present invention is not limited thereto, and some steps may be omitted or other general steps may be added, and the steps of the operation method (600) of the simulation system may be executed in a different order than the illustrated order.

[0072] The operation method (600) of the simulation system may be composed of steps that are processed in a time-series manner in the simulation system (120). Therefore, even if the content is omitted below, the content described above for the simulation system (120) may be equally applied to the operation method (600) of the simulation system.

[0073] Steps (610) to (640) of the operation method (600) of the simulation system can be performed by the interface panel (121), the main simulator (122), and the display (123) of the simulation system (120).

[0074] In step (610), the simulation system (120) can receive operation input from an operator through an interface panel.

[0075] At step (620), the simulation system (120) can load training content that reproduces the EOL process for manufacturing a cylindrical battery based on the operational input through the main simulator.

[0076] At step (630), the simulation system (120) can provide training content to the worker through interaction with the worker through the main simulator.

[0077] In step (640), the simulation system (120) can display detailed images according to detailed processes of the EOL process through a display.

[0078] According to an embodiment, the operation method (600) of the simulation system may be implemented in the form of a computer program stored on a computer-readable storage medium. That is, the computer program may include instructions for implementing the operation method (600) of the simulation system, and the instructions of the program may be stored on a computer-readable storage medium. The computer program may include a mobile application.

[0079] According to an embodiment, the computer-readable storage medium may include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs, DVDs, magneto-optical media such as floptical disks, and hardware devices specially configured to store and execute computer program instructions such as ROMs, RAMs, flash memories, and the like. The computer program instructions may include machine language codes generated by a compiler and high-level language codes that can be executed by a computer using an interpreter, etc.
