[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.

Recently, their use has expanded to include power sources for electric vehicles, attracting attention as a next-generation energy storage medium.

[0057] The interface panel (121) may provide an interface function between the operator (110) and the simulation system (120). For example, the interface panel (121) may receive an operation input for operating the simulation system (120) from the operator (110) in the form of input through an input device such as a touch input, a button input, or a mouse, and may display a graphical interface such as a screen that assists in selecting the operation input. According to an embodiment, the interface panel (121) may include an HMI (Human Machine Interface) panel.

[0058] The main simulation device (122) may be configured to execute a simulation related to the manufacture of a cylindrical battery. The main simulation device (122) may interact with the operator (110) to facilitate the simulation. For example, the main simulation device (122) may receive a touch input or a drag input from the operator (110), change the assembly state of the virtual battery accordingly, and display the changed assembly state to the operator (110). The main simulation device (122) may include a processor and memory for executing simulation software.

[0059] The processor of the main simulation device (122) may have a structure for executing instructions that implement the operations of the main simulation device (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.

[0060] The memory 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 and / or storage to perform various operations. The memory and / or storage may store various data, instructions, mobile applications, computer programs, etc. For example, the memory and / or 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.

[0061] 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 on the main simulation device (122). For example, when a manufacturing process of a cylindrical battery is performed on the main simulation device (122), an external image of the corresponding process that is recognizable to the naked eye may be displayed on the main simulation device (122), and an image of an invisible area of ​​the corresponding process that is not recognizable may be displayed on the display (123).

[0062] The interface panel (121) of the simulation system (120) may be configured to receive operation input from a worker (110). The worker (110) may generate operation input through touch input, button input, mouse input, etc. The operation input may be utilized for driving the main simulation device (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 operation panel used in an actual manufacturing line.

[0063] The main simulation device (122) of the simulation system (120) may be configured to load training content that recreates a battery manufacturing process 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 identically recreates an actual manufacturing process of a cylindrical battery. In an embodiment, the battery manufacturing process may include cylindrical processes sequentially performed to manufacture a cylindrical battery. Alternatively, the battery manufacturing process may include processes for manufacturing batteries of other types than cylindrical batteries.

[0064] The main simulation device (122) of the simulation system (120) may be configured to provide training content to the worker (110) through interaction with the worker (110). For example, in the case of a cathode tab welding (CTW) process for manufacturing a cylindrical battery, the worker (110) may indirectly experience the process of forming a cathode tab through welding through the training content. According to an embodiment, the worker (110) may apply touch and drag inputs to the main simulation device (122), and accordingly, the main simulation device (122) may display the process of welding the cathode tab. According to an embodiment, input to the equipment operation panel in an actual manufacturing line may be implemented as input to the interface panel (121), and operations that the worker (110) must directly perform in an actual manufacturing line may be implemented as input to the main simulation device (122).

[0065] The display (123) of the simulation system (120) may be configured to display detailed images of the manufacturing process based on the characteristics of the training content. For example, in quality inspection content through dimensional measurement, detailed images regarding dimensional measurements of a measurement target may be displayed on the display (123), and in the case of a cathode tab welding process, an enlarged image of the cathode tab portion where welding is in progress may be displayed on the display (123).

[0066] In an embodiment, the battery manufacturing process includes cylindrical processes sequentially performed to manufacture a cylindrical battery, and the training content may include at least one of process guide content, equipment operation content, quality assurance content, and process condition adjustment content for the cylindrical processes. The process guide content may include content explaining the cylindrical processes and virtually experiencing the assembly procedure of the cylindrical processes through simulation.

The quality assurance content may include content virtually experiencing the process of verifying the quality of the process outputs of the cylindrical processes. The process condition adjustment content may include content adjusting the process conditions or process requirements required for the cylindrical processes and verifying changes in the process outputs accordingly. In an embodiment, the battery manufacturing process may include a process for manufacturing a battery of a different form than a cylindrical battery.

[0067] According to an embodiment, the main simulation device (122) of the simulation system (120) is configured to display to the worker (110) a first state in which virtual cylindrical parts assembled in cylindrical processes change in response to the worker's (110) touch input in order to provide process guide content, and the display (123) of the simulation system (120) may be configured to display an invisible area of ​​the virtual cylindrical parts in the first state. When the worker (110) moves the virtual cylindrical parts through touch and drag input, the first state regarding the positional relationship or the coupling relationship of the virtual cylindrical parts may be changed and visually displayed to the worker (110). An image of the invisible area that is not displayed externally in the first state may be displayed through the display (123). According to an embodiment, the process guide content may include providing guide text describing the cylindrical processes.

[0068] In an embodiment, the main simulation device (122) of the simulation system (120) may be configured to evaluate the assembly quality of virtual cylindrical components based on a first state, and to calculate the expected failure rate of a cylindrical battery based on the assembly quality for each of the cylindrical processes. The first state may represent the positional relationship or the coupling relationship of the virtual cylindrical components, thereby enabling the evaluation of the assembly quality. Given a plurality of assembly qualities for a plurality of cylindrical processes, the expected failure rate of the cylindrical battery, which is the final product, may be calculated based on these. In an embodiment, an AI model configured to evaluate the assembly quality based on the first state, and to calculate the expected failure rate based on the assembly qualities may be utilized.

[0069] According to an embodiment, the main simulation device (122) of the simulation system (120) may be configured to select representative failure cases among cylindrical processes based on assembly quality and expected failure rate, and provide additional training content for the representative failure cases to the worker (110). For example, if a specific process among the cylindrical processes consistently shows low assembly quality or has a large impact on the expected failure rate based on accumulated statistical data of result data provided to the worker (110) through process guide content, the process may be selected as a representative failure case.

[0070] According to an embodiment, cumulative statistical data of the result data provided to the worker (110) through the training content of the simulation system (120) may be managed by the simulation management server (130). The simulation management server (130) may receive the result data from the simulation system (120) whenever the training content is provided and record it in a database. The simulation management server (130) may update the type or content of the training content, the training content for defective cases, etc. based on the recorded data, and may provide the update information to the simulation system (120).

[0071] According to an embodiment, the main simulation device (122) of the simulation system (120) is configured to display to the worker (110) a second state in which virtual cylindrical facilities configured to perform cylindrical processes are operated in response to a touch input of the worker (110) in order to provide facility operation content, and the display (123) of the simulation system (120) can be configured to display an invisible area of ​​the virtual cylindrical facilities in the second state. For example, the second state regarding the operation of the virtual cylindrical facilities can be changed through a touch or drag input of the worker (110), and the visible area and invisible area of ​​the virtual cylindrical facilities can be displayed in the second state. According to an embodiment, a task of replacing consumables of the virtual cylindrical facilities can be trained through the facility operation content.

[0072] According to an embodiment, the main simulation device (122) of the simulation system (120) is configured to display to the worker (110) a third state in which samples of assembly results of virtual cylindrical parts assembled in cylindrical processes are collected in response to a touch input of the worker (110) in order to provide quality verification content, and the display (123) of the simulation system (120) may be configured to display a quality determination area of ​​a sample to be inspected in order to verify the quality of the assembly results. For example, in a cathode tab welding (CTW) process, a welding result sample may be collected through an input of the worker (110) in order to verify the welding state of the cathode, and the welding area of ​​the sample may be displayed in detail through the display (123).

[0073] According to an embodiment, the main simulation device (122) of the simulation system (120) is configured to display to the operator (110) the change in the operating form of virtual cylindrical equipment according to the change in the process conditions of the cylindrical processes set in response to the touch input of the operator (110) in order to provide process condition adjustment content, and the display (123) of the simulation system (120) can be configured to display the change in the process results of the cylindrical processes according to the change in the operating form. For example, in a process of forming a jelly roll of a cylindrical battery, when the strength of winding the assembly of the positive electrode, the negative electrode, and the separator is increased or decreased, how the diameter or shape of the jelly roll changes due to such change can be displayed.

In particular, the central screen can display a simulation image of assembling virtual cylindrical parts in each cylindrical process. When a worker (110) drags one part to another in the simulation image, the central screen can display the assembly status of the parts, which is determined based on the accuracy of the drag input.

[0084] The lower screen of the operation screen (500) can provide guidance messages to the operator (110). For example, when a process flow diagram (560) is displayed, guidance text (570) explaining each cylindrical process can be provided through the lower screen. Alternatively, when a simulation image is displayed on the central screen, the lower screen can display precautions for each cylindrical process.
