Description

Training simulation device and user training method using the training simulation device

[0001] This application claims the benefit of the filing date of Korean Patent Application No. 10-2024-0153119 filed with the Korean Intellectual Property Office on November 1, 2024, and all contents disclosed in the document of said Korean patent application are incorporated into this specification.

[0002] The present invention relates to a training simulation device and a user training method using the training simulation device, and more specifically, to a training simulation device for training a winder process during a battery manufacturing process and a user training method using the training simulation device.

[0003] Secondary batteries are batteries that can be reused through charging even after discharge. They can be utilized as energy sources for small devices such as mobile phones, tablet PCs, and vacuum cleaners, and are also used as medium-to-large energy sources for personal mobility devices, automobiles, and energy storage systems. Depending on system requirements, secondary batteries are used in the form of assemblies, such as battery modules in which multiple battery cells are connected in series and parallel, or battery packs in which battery modules are connected in series and parallel.

[0004] Recently, the demand for the development and production of secondary batteries has been rapidly increasing due to the growth of the electric vehicle and energy storage market. In response to this surge in demand, the number of production plants for secondary batteries is also increasing. However, there is a significant shortage of skilled workers to operate these production facilities.

[0005] Furthermore, while the training and education of new workers were previously conducted by having them learn by observing experienced operators, the busy secondary battery production schedule made it difficult to provide long-term training. In addition, there is a problem in securing a sufficient number of skilled workers due to factors such as employee turnover. Moreover, even if workers are trained on general factory operations, it is not easy to ensure they can respond immediately to the various types of defect situations that may occur during operation.

[0006] To address these issues, a method is being utilized in which workers engaged in secondary battery production undergo training via simulators regarding the operation of production equipment and procedures for handling defects before being deployed to work. However, as battery types and specifications change, the secondary battery production process must also adapt accordingly. Consequently, the devices used to simulate the secondary battery production process also require appropriate modifications.

[0007] A related prior art is Korean Patent Publication No. 2023-0076655.

[0008] The objective of the present invention to solve the above-mentioned problems is to provide a simulation device for training the winder process during the battery manufacturing process.

[0009] Another objective of the present invention to solve the above-mentioned problems is to provide a user training method using the training simulation device (simulator).

[0010] A training simulation device according to an embodiment of the present invention for achieving the above objective is a simulation device for training a battery manufacturing process, and may include at least one processor; a memory for storing at least one command executed through the at least one processor; and a user interface unit for visualizing and outputting the result of executing the at least one command.

[0011] The above at least one command includes: a command to implement a process result according to materials input into the process and conditions input into the process; a command to check the operating status of a virtual model equipment performing one or more processes; and a command to implement 3D operation of the virtual model equipment for one or more processes, and the one or more processes may include tab welding and cover tape attachment processes of a cylindrical battery.

[0012] The above tab welding and cover tape attachment processes may be included in the winder process.

[0013] The above training simulation device may further include a 3D training system that implements the operation of 3D equipment through virtual HMI (Human-Machine Interface) control and virtual quality monitoring using a virtual equipment training scenario module; and a simulation engine that generates equipment operation events and generates quality data according to operation training.

[0014] The above simulation engine can operate using a real-time discrete event simulation module.

[0015] The above user interface unit may include: a condition setting unit for setting conditions of one or more adjustment parameters to determine the operation of a virtual model equipment according to user input; an equipment operation unit for operating and displaying the virtual model equipment according to the adjustment parameters; and a quality verification unit for displaying quality information related to the quality of a material generated by the virtual model equipment.

[0016] The above at least one command may further include a command that implements the operation of the virtual model equipment, which changes as the conditions of the adjustment parameters input through the user interface are adjusted.

[0017]

[0018] A user training method using a training simulator according to an embodiment of the present invention for achieving the above other objectives comprises: a step of implementing a process result according to materials introduced into the process and conditions input into the process; a step of checking the operating status of a virtual model equipment performing one or more processes; and a step of implementing a 3D operation of the virtual model equipment for one or more processes, wherein the one or more processes may include tab welding and cover tape attachment processes of a cylindrical battery.

[0019] The above tab welding and cover tape attachment processes may be included in the winder process.

[0020] The above training simulator may further include a 3D training system that implements the operation of 3D equipment through virtual HMI (Human-Machine Interface) control and virtual quality monitoring using a virtual equipment training scenario module; and a simulation engine that generates equipment operation events and generates quality data according to operation training.

[0021] The above simulation engine can operate using a real-time discrete event simulation module.

[0022] The above training simulator may include: a condition setting unit for setting conditions of one or more adjustment parameters to determine the operation of virtual model equipment according to user input; an equipment operation unit for operating and displaying the virtual model equipment according to the adjustment parameters; and a quality verification unit for displaying quality information related to the quality of a material generated by the virtual model equipment.

[0023] The user training method using the above training simulator may further include a step of implementing the operation of the virtual model equipment that changes as the conditions of the adjustment parameters input through the condition setting unit are adjusted.

[0024] According to the embodiment of the present invention as described above, the on-site adaptation period of new workers introduced into the secondary battery manufacturing process can be shortened, and the basic skills and proficiency of workers required for production can be improved early.

[0025] In addition, when expanding a factory, worker training using a simulator is possible even when equipment is not yet available, thereby enabling early improvement in yield.

[0044]

[0045] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the attached drawings.

[0046]

[0047] Figure 1 is a schematic diagram of the battery manufacturing process.

[0048] Generally, a secondary battery can be manufactured through an electrode process (S10), an assembly process (S20), an activation process (S30), and a packaging process (S40). The battery completed through these processes is shipped in the form of a battery pack (or battery module) comprising a plurality of battery cells connected in series. The battery pack can be connected to a load through positive and negative terminals to perform charging and discharging operations, and can be configured by connecting in series or parallel according to the requirements of the system in which the battery is used.

[0049] More specifically, the electrode process (S10) proceeds in the order of a ‘mixing process’ for mixing raw materials, a ‘coating process’ for applying the mixed slurry to a foil and drying it, a ‘roll pressing process’ for reducing the thickness of the electrode, a ‘slitting process’ for cutting the electrode, and finally a ‘notching process’ for making a tab on the electrode.

[0050] In the present invention, the 'mixing process' may be a process of preparing a slurry by mixing an active material, a binder, and other additives with a solvent. For example, the user may determine or adjust the ratio of the addition of the active material, conductive material, additives, binder, etc., to prepare a slurry of a specific quality.

[0051] The 'coating process' may be a process of applying a slurry onto a foil in a specific amount and shape. For example, the user may determine or adjust the die of the coater device, the slurry temperature, etc., to perform a coating of a specific quality and shape.

[0052] The 'roll pressing process' may be a process of passing a coated electrode between two rotating upper and lower rolls to press it to a uniform thickness. For example, the user may determine or adjust the spacing between the rolls to increase electrode density through the roll pressing process and maximize the capacity of the battery. Additionally, in the present invention, the 'slitting process' may be a process of passing an electrode between two rotating upper and lower knives to cut the electrode to a uniform width. For example, the user may determine or adjust various adjustment parameters to maintain a uniform electrode width.

[0053] The 'notching and drying process' may be a process of removing moisture after punching the electrode into a specific shape. For example, the user may determine or adjust the cutting height, length, etc. to perform punching into a shape of a specific quality. Additionally, in the present invention, the 'lamination process' may be a process of sealing and cutting the electrode and the separator. For example, the user may determine or adjust values ​​corresponding to the x-axis, values ​​corresponding to the y-axis, etc. to perform cutting of a specific quality.

[0054] Meanwhile, the assembly process (S20) is a process of assembling the positive and negative plates, which are completed through the electrode process, by adding a separator and an electrolyte. The assembly process method may vary depending on the battery type. Batteries can be classified into cylindrical, pouch, or prismatic types, and the method of stacking the electrode plates may vary depending on the battery type.

[0055] In the process of assembling cylindrical batteries, a 'winding' method is used in which the positive plate is rolled into a roll resembling toilet paper with a separator in between. At this stage, four rolls (positive roll, negative roll, and two separator rolls) are mounted on a winder, wound onto a mandrel, and cut to an appropriate size to form a jelly roll. Once the jelly roll is completed, the positive and negative tabs are attached to the jelly roll, and the jelly roll is inserted into the cylindrical battery can. The jelly roll inside the can is then secured through welding and beading. Finally, the battery assembly process is completed by injecting the electrolyte into the vacuum-sealed can through a nozzle.

[0056] Additionally, the activation process (S30) is a process for activating electrical energy and verifying stability. The final packaging process (S40) is a process for modularizing and packaging the manufactured battery cells.

[0057] As seen in Figure 1, producing secondary batteries requires numerous detailed processes, and high work quality is required for each detailed process. In addition, as the demand for secondary batteries increases, the demand for skilled workers is on the rise.

[0058] Accordingly, a method is being utilized in which workers engaged in secondary battery production undergo training through simulation devices regarding the operation of secondary battery production equipment and methods for handling defects before being deployed to work.

[0059]

[0060] FIG. 2 is a drawing showing an example of a user interface of a simulation device according to one embodiment of the present invention.

[0061] Referring to FIG. 2, the simulation device (100) is a device for training a worker (referred to as "user" in this specification) who produces a secondary battery, and provides various user interfaces to the user. In an embodiment of the present invention, the simulation device may particularly include a simulator for training a winder used in the process of manufacturing a 2170 (diameter 21 mm · length 70 mm) cylindrical battery.

[0062] A user interface according to an embodiment of the present invention may be configured to include a condition setting unit (110), an equipment operation unit (120), and a quality verification unit (130). Accordingly, the user can learn how to use the secondary battery production equipment (e.g., a winder) or train on how to respond when quality degradation of the produced product occurs by operating the condition setting unit (110), the equipment operation unit (120), and the quality verification unit (130) provided by a simulation device that virtually implements the actual secondary battery production equipment (e.g., 2D, 3D, etc.).

[0063] According to one embodiment, the condition setting unit (110) can be implemented using a Human-Machine Interface (HMI) and is a device implemented to allow a user to adjust one or more adjustment parameters for determining the operation of a virtual model equipment displayed on an equipment operation unit (120). The user can operate the operation and stop of the equipment through the condition setting unit (110) and can execute, change, and / or correct the operation of the 2D / 3D virtual model equipment by changing at least some of the conditions among the adjustment parameters. That is, the operation of the virtual model equipment can be adaptively changed or corrected by changes in the adjustment parameters input by the user.

[0064] The equipment operation unit (120) can be implemented using virtual model equipment associated with the production of secondary batteries. Here, the virtual model equipment may include 2D / 3D virtual model equipment / devices associated with secondary battery production equipment such as a mixer, coater, slitter, winder, roll presser device, lamination device, L&S (lamination & stack) device, etc.

[0065] More specifically, the equipment operation unit (120) can provide materials and results fed into the winder process in 3D. The equipment operation unit (120) can also check the operation / operation status (start, stop, individual part operation) of the equipment (i.e., virtual model equipment) and provide detailed operations for the cylindrical winder detailed process in 3D. The implementation and provision of such operations can be implemented along an automatic path line from the start to the end of the process. In particular, the embodiment of the present invention includes tab welding and cover tape attachment processes during the winder process.

[0066] According to an embodiment, the user can operate the virtual model equipment or change the configuration of the virtual model equipment through input to the virtual model equipment represented by the equipment operation unit (120). In this case, the user can check or zoom in / out of any area of ​​the virtual model equipment through view switching, etc., and can operate the virtual model equipment or change the configuration of the virtual model equipment by performing touch input, etc.

[0067] Meanwhile, the equipment operation part (120) of the simulation device can operate through processes such as a process and equipment guide stage, a material preparation stage, an operation training stage, a case training stage, and a test stage. Through these stages, the user can train on how to operate the secondary battery production equipment.

[0068] The Process and Equipment Guide stage explains the secondary battery production process or equipment. The Material Preparation stage prepares the materials required for the process. In the Operation Training stage, the user can review work standards and process conditions and train in the operation of the winder. The Case Training stage may be a stage where the user masters defect resolution methods by repeatedly handling or resolving each or a combination of multiple defect scenarios associated with the secondary battery production equipment. Additionally, the Testing stage may be a stage to evaluate the user's operational capabilities by testing the process of resolving defect scenarios.

[0069] The quality verification unit (130) can display quality information related to the quality of a material generated by the virtual model equipment through a vision screen. Here, the quality information can be generated by performing calculations on quality parameters, etc. based on predetermined criteria and / or algorithms. That is, the user can check the quality information generated in response to changing adjustment parameters or operating the virtual model equipment through the quality verification unit (130).

[0070] In particular, the present invention aims to provide a training simulation device for training the winder process during a battery manufacturing process and a user training method using the same.

[0071]

[0072] FIG. 3 illustrates an example of simulating winder process training according to an embodiment of the present invention.

[0073] The embodiment of FIG. 3 shows an example of an HMI screen specialized for the winder process used to manufacture cylindrical 2170 batteries, a simulator screen implementing 3D equipment operation and product change for each detailed process.

[0074] The main simulator screen is an example of an equipment operation unit (120) according to an embodiment of the present invention, and displays 3D equipment operation and product change for each detailed winder process. Here, the 3D equipment operation for each detailed winder process may be an operation using electrode supply, conveyor, seal tape, conveyor, fusion, cover tape, winding unit, separator, etc., as shown in FIG. 3. More specifically, the equipment operation for each detailed winder process may include operations such as adjusting the tab fusion position, adjusting the tab protrusion length, adjusting the tab protection tape position, adjusting the tilt of the horn (fusion equipment part), and replacing the fusion equipment part. At this time, the 3D equipment operation for each detailed winder process may be implemented by utilizing 3D rendering and animation techniques to show the operation of each piece of equipment.

[0075] Meanwhile, depending on the scenario of each training stage, guide information may be displayed or output on virtual model equipment, the types of adjustment parameters to be operated for verification and adjustment, the values ​​of adjustment parameters, operation buttons, 3D model devices, etc. That is, work instructions may be displayed or output on the equipment operating parts, etc., and a part of the screen may be lit or activated so that the user can perform a task corresponding to the work instructions. In this case, the user can operate the equipment operating parts and equipment operating parts corresponding to the work instructions and input setting values, and when one task is completed, the next step proceeds, or a button to proceed to the next step (e.g., NEXT button, etc.) may be displayed or activated. Thus, the user can train the operation process of a slitter for secondary battery production based on the information displayed in this way.

[0076] As such, the present invention allows the cylindrical battery winder process to be constructed as a virtual environment identical to the actual one through 3D modeling and animation. The virtual environment according to the embodiment of the present invention is configured as a work environment identical to the actual one by reflecting the movement path of the actual worker. In addition, the internal operation of the equipment, which cannot be seen during actual operation, can be realized by utilizing 3D rendering and animation techniques. In particular, the training simulation device according to the embodiment of the present invention is implemented so that a worker can train by operating virtual equipment in a virtual space equipped with actual working conditions and an environment identical to the actual winder process of a cylindrical 2170 battery.

[0077]

[0078] FIG. 4 is a flowchart exemplarily illustrating the operation process of a training simulation device according to one embodiment of the present invention.

[0079] As illustrated, the simulation device can operate through processes such as the process and equipment guide step (S410), material preparation step (S420), operation training step (S430), quality verification step (S440), and condition adjustment step (S450). In other words, the user can train on how to operate the secondary battery production equipment through these steps. The process illustrated in FIG. 4 is exemplary and may include additional steps, or one or more of the described steps may be omitted.

[0080] The process and equipment guide step (S410) may be a step for describing a secondary battery production process or equipment. If the 3D model device is a winder, the description of the production process or equipment may include a description of the composition of the jelly roll (positive electrode, negative electrode, separator 1, 2, seal tape) and a description of the winder equipment. Here, the description of the winder equipment may include a description of the electrode unwinder section, tab welding section, cover tape attachment section, separator unwinder section, seal tape attachment section, winding section, conveyor transfer section, workbench / waste bin, and their components.

[0081] The material preparation step (S420) is a process of preparing materials required for the process, which can be done by replacing electrodes, separators, connecting tapes, seal tapes, cover tapes, fusion horns / anvils, etc.

[0082] The operation training step (S430) is a step in which the user checks the work standard and process conditions and trains the operation of the winder.

[0083] The quality verification step (S440) verifies the quality of the process result by checking the jelly roll appearance inspection, meandering inspection, jelly roll core input amount, jelly roll internal dimensions, etc. Here, the jelly roll appearance inspection may include inspection items such as total height, tab protrusion length, seal tape attachment position, and meandering. The meandering inspection may include inspection using X-rays. Meanwhile, the jelly roll core input amount may include the remaining separator amount, core input amount, separator input amount, etc. Additionally, the jelly roll internal dimensions may include electrode length, tab forming height, seal tape position / length, tab height / length, etc.

[0084] In the condition adjustment step (S450), the conditions or values ​​of adjustment parameters that are determined to require adjustment through quality verification can be changed. In the winder process, adjustment parameters may include tab forming height, meandering, input amount, fusion conditions, cover tape conditions, electrode length, seal tape length / position, etc.

[0085] Meanwhile, although not explicitly stated, a test phase may be included to evaluate the user's operational capability by testing the process of the user completing training scenarios. For example, when a user completes each training scenario, their operational capability may be measured or evaluated based on the completion time, loss values, etc., for each scenario. By checking this operational capability and whether they passed the test, the user can further study or train on the training scenarios where they are lacking.

[0086]

[0087] FIG. 5 is a conceptual diagram of the operation of a simulation device according to an embodiment of the present invention.

[0088] A simulation device according to one embodiment of the present invention may include: a 3D training system (510) that implements the operation of 3D equipment through virtual HMI control and virtual quality monitoring using a virtual equipment training scenario module based on process and equipment guide, operation training, and quality verification; and a simulation engine (520) that generates equipment operation events and generates quality data.

[0089] According to another embodiment, the simulation device of the present invention may be configured to be implemented as separate hardware from the 3D training system (510) and the simulation engine (520) and to interact with each other. The 3D training system (510) and the simulation engine (520) may be linked with a simulator PC (including a main simulator, HMI, and vision screen). Additionally, the 3D training system (510) and the simulation engine (520) may be implemented by being included in a system update agent or by interacting with a system update agent.

[0090] Here, the simulation engine (520) can operate using a real-time discrete event simulation module. The real-time discrete event simulation module can generate equipment operation events (start / stop, reflection of operation functions) and generate quality data. At this time, the quality data may include quality measurement and sample inspection data, defect types, and results of determining good or defective. The simulation engine (520) can connect and communicate with the 3D training system (510) through an API (application programming interface).

[0091]

[0092] FIG. 6 is a block diagram of a simulation device according to an embodiment of the present invention.

[0093] A simulation device (100) according to an embodiment of the present invention is a training simulation device for training a winder process and may include at least one processor (101), a memory (102) for storing at least one command executed through the processor, and a transmitting and receiving device (103) connected to a network to perform communication.

[0094] The above at least one command includes: a command to implement a process result according to materials input into the process and conditions input into the process; a command to check the operating status of a virtual model equipment performing one or more processes; and a command to implement 3D operation of the virtual model equipment for one or more processes, and the one or more processes may include tab welding and cover tape attachment processes of a cylindrical battery.

[0095] The above tab welding and cover tape attachment processes may be included in the winder process.

[0096] The above training simulation device may further include a 3D training system that implements the operation of 3D equipment through virtual HMI (Human-Machine Interface) control and virtual quality monitoring using a virtual equipment training scenario module; and a simulation engine that generates equipment operation events and generates quality data according to operation training.

[0097] The above simulation engine can operate using a real-time discrete event simulation module.

[0098] The simulation device (100) may also include a user interface comprising: a condition setting unit (110) for setting conditions of one or more adjustment parameters to determine the operation of a virtual model device according to user input; an equipment operation unit (120) for operating and displaying the virtual model device according to the adjustment parameters; and a quality verification unit (130) for displaying quality information related to the quality of a material generated by the virtual model device.

[0099] The above at least one command may further include a command that implements the operation of the virtual model equipment, which changes as the conditions of the adjustment parameters input through the user interface are adjusted.

[0100] Meanwhile, at least one processor (101) of the simulation device (100) is connected to a condition setting unit (110), an equipment operation unit (120), and a quality verification unit (130) to exchange data or information related to virtual model equipment. Although FIG. 6 shows the simulation device (100) including a condition setting unit (110), an equipment operation unit (120), and a quality verification unit (130), each of the condition setting unit (110), the equipment operation unit (120), and the quality verification unit (130) may be implemented in a form that is configured as separate hardware (e.g., a user interface) and interacts with the simulation device (100).

[0101] The processor (101) can execute, change, or correct the operation of the 3D virtual model equipment displayed on the equipment operation unit (120) according to the operation of the user. According to one embodiment, the processor (101) can acquire or receive user behavior information and user condition information using information input from the user (secondary battery production worker). The processor (101) can also determine or change the operation of the virtual model equipment using the acquired or received user behavior information and user condition information.

[0102] User behavior information is information generated based on user input, such as touching at least a portion of the virtual model equipment included in the equipment operation part (120), and may include information regarding the amount of change in the setting value of the virtual model equipment according to the user input.

[0103] User condition information is information generated based on user input that changes the condition or value of at least some of the adjustment parameters included in the condition setting unit (110), and may include information regarding the amount of change of the condition value for determining the operation of the virtual model equipment according to the user input.

[0104] When the operation of the virtual model equipment is executed based on user condition information or user behavior information, the processor (101) can determine or generate quality information related to the quality of the material generated by the operation of the virtual model equipment. In other words, when the virtual model equipment is operated (when animation, video, etc. are executed by the virtual model equipment), the quality information may be determined or generated differently depending on the setting value, condition value, etc. of the virtual model equipment. In other words, the user can change or adjust the quality of the material generated by the virtual model equipment by changing adjustment parameters or by setting at least a part of the virtual model equipment to touch input, etc.

[0105] The processor (101) can determine or extract one or more quality parameters to determine the quality of a material generated by a virtual model device, and while the operation of the virtual model device is being executed, it can calculate a value corresponding to each of the one or more quality parameters determined based on the operation of the virtual model device being executed. Here, the value corresponding to the quality parameter may be calculated by any predetermined algorithm. Additionally, the processor (101) can generate quality information associated with the quality of the material generated by the virtual model device based on the value corresponding to each of the one or more quality parameters calculated.

[0106] Additionally, the processor (101) determines whether one or more defect scenarios have been resolved using corrected quality information, and if it is determined that one or more defect scenarios have been resolved, it can calculate the duration of one or more defect scenarios, loss values, etc., while the one or more defect scenarios are in progress. For example, the loss values ​​may include coating loss values, material loss values, etc., and may be calculated through a predetermined arbitrary algorithm based on the user's response time, values ​​entered by the user, etc. Additionally, if the user has resolved all predetermined types of defect scenarios, the processor (101) may determine whether the user has passed the simulation training based on operational capability information for each defect scenario.

[0107] Meanwhile, the simulation device (100) according to an embodiment of the present invention may further include a storage device (106), etc. Here, the processor (101) may refer to a central processing unit (CPU), a graphics processing unit (GPU), or a dedicated processor on which methods according to embodiments of the present invention are performed. The storage device (or memory) may be composed of at least one of a volatile storage medium and a non-volatile storage medium. For example, the memory may be composed of at least one of read-only memory (ROM) and random access memory (RAM).

[0110] A user training method using a simulation device according to an embodiment of the present invention is a user training method using a simulator that trains the winder process during a battery manufacturing process.

[0111] Referring to FIG. 7, a training simulator according to an embodiment of the present invention can implement a process result according to materials introduced into the process and conditions input into the process (S710). Here, one or more processes may include tab welding and cover tape attachment processes among the winder processes of a cylindrical battery.

[0112] The training simulator can also check the operating status of a virtual model equipment performing one or more processes (S720) and implement 3D operation of the virtual model equipment (S730).

[0113] Here, the training simulator may include a 3D training system that implements the operation of 3D equipment through virtual HMI (Human-Machine Interface) control and virtual quality monitoring using a virtual equipment training scenario module; and a simulation engine that generates equipment operation events and generates quality data according to operation training. The simulation engine may operate using a real-time discrete event simulation module.

[0114] Meanwhile, when the condition of the adjustment parameter input through the condition setting section of the user interface is adjusted (S740), the operation of the virtual model equipment that changes according to the condition value of the adjusted adjustment parameter can be implemented (S750).

[0115] Here, the user interface may include: a condition setting unit for setting conditions of one or more adjustment parameters to determine the operation of a virtual model equipment according to user input; an equipment operation unit for operating and displaying the virtual model equipment according to the adjustment parameters; and a quality verification unit for displaying quality information related to the quality of a material generated by the virtual model equipment.

[0116] Here, the user can input conditions and / or condition adjustment values ​​of adjustment parameters to determine the operation of the virtual model equipment through the condition setting section (e.g., HMI).

[0117]

[0118] According to an embodiment of the present invention as described above, the on-site adaptation period of new workers introduced into the secondary battery manufacturing process can be shortened, and the basic skills and proficiency of workers required for production can be improved early.

[0119] In addition, when expanding a factory, worker training using a simulator is possible even when equipment is not yet available, thereby enabling early improvement in yield.

[0120]
