[0047] The main simulation device (122) may be configured to perform a simulation regarding the manufacture of a cylindrical battery. The main simulation device (122) may interact with the operator (110) to proceed with the simulation. For example, the main simulation device (122) may receive touch input or 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 running simulation software.

For example, training content may be booted via operation input, and the training content may include a training simulation that identically reconstructs the actual manufacturing process of a cylindrical battery. According to an embodiment, the battery manufacturing process may include cylindrical processes performed sequentially to manufacture a cylindrical battery. Alternatively, the battery manufacturing process may include a process for manufacturing a battery of a shape other than a cylindrical battery.

[0053] The main simulation device (122) of the simulation system (120) may be configured to provide training content to the operator (110) through interaction with the operator (110). For example, in the case of a cathode tab welding (CTW) process for manufacturing a cylindrical battery, the operator (110) may indirectly experience the process of forming a cathode tab through welding through training content. According to an embodiment, the operator (110) may apply touch and drag input to the main simulation device (122), and accordingly, the main simulation device (122) may display the process of welding the cathode tab.

An image of an 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 the provision of guide text describing the cylindrical processes.

[0057] According to an embodiment, the main simulation device (122) of the simulation system (120) may be configured to evaluate the assembly quality of virtual cylindrical parts based on a first state and to calculate the expected defect rate of the cylindrical battery based on the assembly quality for each of the cylindrical processes. Since the first state may represent the positional relationship or connection relationship of the virtual cylindrical parts, the assembly quality can be evaluated through this. Given multiple assembly quality values ​​for multiple cylindrical processes, the expected defect rate of the cylindrical battery, which is the final product, can be calculated through these values. According to an embodiment, an AI model configured to evaluate the assembly quality based on the first state and to calculate the expected defect rate based on the assembly quality values ​​may be utilized.

[0058] According to an embodiment, the main simulation device (122) of the simulation system (120) may be configured to select a representative defect case among cylindrical processes based on assembly quality and expected defect rate, and to provide additional training content for the representative defect case to the operator (110). For example, based on the cumulative statistical data of result data provided to the operator (110) with process guide content, if a specific process among the cylindrical processes consistently shows low assembly quality or if a specific process has a significant impact on the expected defect rate, that process may be selected as a representative defect case.

[0059] According to an embodiment, the cumulative statistical data of result data provided to the worker (110) with training content of the simulation system (120) can be managed by the simulation management server (130).

For example, the second state regarding the operation of the virtual cylindrical equipment may be changed through the touch or drag input of the operator (110), and the visible and non-visible areas of the virtual cylindrical equipment may be displayed in the second state. According to an embodiment, the task of replacing consumables of the virtual cylindrical equipment may be trained through the equipment operation content.
