[0039] Referring to FIG. 1, a simulation system (120) can provide simulation content to a worker (110). A simulation management server (130) can manage the content of the simulation system (120).

[0040] The simulation system (120) can provide simulation training to the worker (110) regarding the manufacturing process of a cylindrical battery.

[0041] The simulation management server (130) may be configured to manage training content provided by the simulator system (120). The simulation management server (130) may record the performance results of the training content and derive statistical data based thereon. The simulation management server (130) may add or change the content of the training content based on the statistical data and transmit the added or changed information to the simulator system (120). According to an embodiment, the simulation management server (130) may install content management software in the simulator system (120) and provide update information for the content management software.

[0042] FIG. 2 may illustrate elements that constitute a simulation system according to some embodiments.

[0043] Referring to FIG. 2, the simulator 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).

[0044] According to an embodiment, the interface panel (121), the main simulator (122), and the display (123) may 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.

[0045] The interface panel (121) can provide an interface function between the operator (110) and the simulation system (120). For example, the interface panel (121) can be configured in the form of an HMI (Human Machine Interface) panel. The interface panel (121) can receive an operation input for operating the simulation system (120) from the operator (110) in the form of a touch input, a button input, a mouse input, or the like. The interface panel (121) can provide a graphical interface, such as a screen that provides a selection of operation inputs.

[0046] The main simulator (122) may be configured to run a simulation of the cell packaging process of a cylindrical battery. 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), perform process steps of the cylindrical battery accordingly, and display the results generated at each process step to the operator (110). The main simulator (122) may include a processor and memory for executing simulation software.

[0047] The processor of the main simulator (122) may have a structure for executing instructions for implementing the simulation. The processor may be implemented as an array of multiple logic gates for processing various operations or as a general-purpose microprocessor, and may consist 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.

[0048] The memory or storage of the main simulator (122) 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 process various operations. The memory and / or storage may store various data, instructions, software, 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.

[0049] The display (123) may include a display panel that provides various visual information to the operator (110). The display (123) may display detailed images of a simulation being executed in the main simulator (122). For example, when a cell packaging process of a cylindrical battery is performed in the main simulator (122), external images recognizable to the naked eye in each process may be displayed through the main simulator (122), and images of invisible areas that cannot be recognized to the naked eye may be displayed through the display (123).

[0050] The interface panel (121) may be configured to receive process dimension values ​​of simulation content for operating a virtual facility to perform a cell packaging process from a worker (110). The worker (110) may set process dimension values ​​corresponding to detailed processes of the cell packaging process. The process dimension values ​​may be process parameters for determining the dimensions of a cylindrical battery cell. For example, reference may be made to FIGS. 4 to 6, which will be described later, for examples of process dimension values.

[0051] The main simulator (122) may be configured to display operational processes that the virtual device performs in detail during the cell packaging process. For example, the main simulator (122) may display processes such as assembling a battery cap onto a battery can containing a rolled jelly roll and electrolyte, applying pressure to the battery cap to seal a cylindrical battery cell, and adjusting the size of a cylindrical battery cell. The operational processes may be performed by the virtual device within the simulation content. In some embodiments, at least some of the operational processes may be displayed on the display (123) instead of or in addition to the main simulator (122).

[0052] The main simulator (122) can be configured to generate detailed shapes of process results formed by detailed processes according to process dimension values ​​based on a simulation model of simulation content. When process dimension values ​​are input by the operator (110), the simulation model can generate detailed shapes of process results corresponding to the values. For example, if the dimensions of a battery can or battery cap vary for a pressing operation of the same press mold, the shape obtained as a result of the pressing operation may vary. The simulation model can be pre-built based on actual press mold pressing results for various dimensional values.

[0053] The main simulator (122) may be configured to display detailed shapes to the operator (110). The operator (110) can confirm, through simulation content, how the detailed shapes are formed as a result of the process dimension values ​​he or she inputs. According to an embodiment, the display (123) may 3D model the process result shapes inside the battery cell, which are difficult to see with the naked eye, among the detailed shapes, and display them to the operator (110).

[0054] According to an embodiment, the cell packaging process may include a packaging process for a cylindrical battery cell, and the packaging process for the cylindrical battery cell may be configured to manufacture the cylindrical battery cell by injecting an electrode assembly and an electrolyte into a cylindrical can, joining a cap assembly to the cylindrical can, and sealing the cylindrical can and the cap assembly. Through the packaging process for the cylindrical battery cell, the electrode assembly and the electrolyte may be sealed by the cylindrical can and the cap assembly. The packaging process may be reproduced as simulation content, through which the operator (110) may identify variations in detailed shapes and interference with the mold.

[0055] According to an embodiment, the detailed processes may include a swaging process, a beading process, a primary crimping process, a secondary crimping process, and a sizing process. The swaging process may include a process of compressing an opening of a cylindrical can to reduce an outer diameter. The beading process may include a process of forming a neck at the top of the cylindrical can to facilitate attachment of a cap assembly. The primary crimping process and the secondary crimping process may include a process of pressurizing and sealing the opening of the cylindrical can using a mold or a jig. The sizing process may include a process of adjusting the overall height of a sealed cylindrical cell. Such detailed processes may be reproduced as simulation content.

[0056] According to an embodiment, the interface panel (121) may be configured to receive adjustment values ​​for process dimension values ​​from the operator (110), and the main simulator (122) may be configured to display to the operator (110) both the pre-adjustment shape and the post-adjustment shape of the detailed shapes before and after the adjustment of the process dimension values ​​by the adjustment values. The operator (110) may check the detailed shapes corresponding to the current process dimension values ​​through the simulation system (120), and in response, may set the adjustment values ​​for the process dimension values. For example, if scratches or dents occur in the battery cell due to excessively large dimensions, the operator (110) may reduce the process dimension values. Once the process dimension values ​​are adjusted, the main simulator (122) may display the result of the adjustment. By displaying the shapes before and after the adjustment together, the operator (110) may optimize the process dimension values ​​to the most appropriate value.

[0057] According to an embodiment, the main simulator (122) may be configured to display information regarding stress occurring at contact points between mold structures and detailed shapes of a virtual facility corresponding to detailed processes. When interference occurs between the mold structures and detailed shapes, stress may occur at the contact points. The main simulator (122) may display the intensity of the stress corresponding to the interference through a simulation model. The simulation model may be configured to determine the intensity of the interference based on the size difference between the mold structures and detailed shapes.

[0058] According to an embodiment, the main simulator (122) may be configured to calculate the risk of appearance defects of a battery cell according to the current state of process dimension values ​​based on information about stress. Based on the information about stress, the risk of scratches or dents occurring on the surface of the battery cell due to the pressure of the mold press may be calculated. For example, the risk of appearance defects may include the probability of scratches or dents occurring and / or the severity of the scratches or dents. The risk of appearance defects may be calculated by a simulation model of the simulation content. The operator (110) may check the risk of appearance defects and adjust the process dimension values ​​in a direction to reduce the risk value.

[0059] Figure 3 may illustrate the structure of a simulation system according to some embodiments.

[0060] 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).

[0068] In the beading process (700), a jelly roll injected into a cylindrical can may be pressurized by a sleeve and a pusher, and at the same time, vertical pressure may be applied to the top of the cylindrical can. As a result, a neck portion may be formed that separates the portion where the jelly roll is positioned from the portion where it is joined to the cap assembly.

[0069] FIG. 8 may illustrate how the first clamping process and the second clamping process are performed according to some embodiments.

[0070] Referring to FIG. 8, an example of how the first clamping process (810) and the second clamping process (820) are performed can be illustrated.

The first clamping process (810) and the second clamping process (820) may apply pressure to the upper portion located higher than the neck of the cylindrical can and the cap assembly accommodated within the upper portion to deform the pressurized portion. The deformed pressurized portion may be rolled into the central portion of the cell, thereby sealing the jelly roll and electrolyte inside the cell.

[0072] FIG. 9 may illustrate information regarding stress occurring at contact points between mold structures and detailed shapes of a virtual installation according to some embodiments.
