[0042]

[0043] Figure 1 shows a general battery manufacturing process, and Figure 2 shows a battery manufacturing process system according to an embodiment of the present invention.

[0044] A battery can be manufactured by sequentially proceeding through multiple unit processes. More specifically, the battery manufacturing process can be classified into N unit processes as illustrated in FIG. 1, and the battery can be manufactured by sequentially proceeding through the first to the Nth process.

[0045] For example, unit processes classified as an electrode coating process (Process 1), an electrode rolling process (Process 2), an assembly process (Process 3), an activation process (Process 4), and an EOL (End Of Line) process (Process 5) can be carried out sequentially to manufacture a battery cell.

[0046] Each unit process may consist of multiple detailed processes that proceed sequentially.

[0047] For example, the assembly process of a cylindrical battery cell may proceed sequentially with detailed processes such as JRS (Jelly Roll Supply), CCW (Current Collector Welding), CIT (Cathode Insulation Taping), ISI (Insulator Inserting), JRI (Jelly Roll Inserting), CRW (Cathode Rivet Welding), CBD (Can Beading), ABW (Anode Tag Beading Welding), X-ray, ELF (Electrolyte Filling), CCR (Can Crimping), CSZ (Can Sizing), Washing, CTA (CT in Assembly line), AIA (Appearance Inspection in Assembly line), and IOU (IR-OCV measurement and cell Unloading).

[0048] A battery cell manufacturing process system may be composed of multiple process facilities that perform each of the unit processes. Here, a unit process facility may be composed of a combination of multiple detailed process facilities.

[0049] For example, as shown in FIG. 2, the assembly process equipment for a cylindrical battery cell may include process equipment that sequentially performs detailed processes such as JRS, CCW, CIT, ISI, JRI, CRW, CBD, ABW, X-ray, ELF, CCR, CSZ, Washing, CTA, AIA, and IOU.

[0050] Each of the process facilities includes a transfer line for battery cells, and the detailed process facilities can be connected via transfer units such as conveyors. Accordingly, battery cells are sequentially transferred to the process facilities, and the manufacturing process can proceed.

[0051] To monitor the operating status of such battery manufacturing process systems or to train workers on the battery manufacturing process, a simulator that models the battery manufacturing process system in a virtual space and visualizes the operation of the battery manufacturing process system can be utilized.

[0052] Generally, the operation of a battery manufacturing process system is produced as a single video. Accordingly, if any process equipment is added, removed, or modified in the battery manufacturing process system, the entire video must be newly produced.

[0053] The present invention is a technology devised to solve these problems. Hereinafter, the present invention and various embodiments of the present invention will be described in detail with reference to the attached drawings.

[0054]

[0055] FIG. 3 is a flowchart of the operation of a method for constructing a manufacturing process simulator according to an embodiment of the present invention, and FIGS. 4 to 6 are reference diagrams for explaining a method for constructing a manufacturing process simulator according to an embodiment of the present invention.

[0056] A method for constructing a manufacturing process simulator can be performed by a device for constructing a manufacturing process simulator (hereinafter, simulator construction device).

[0057] The simulator construction device according to the present invention can construct a simulator for a manufacturing process system. Here, the manufacturing process system may include a plurality of process facilities that perform unit process steps for manufacturing an article to be manufactured. For example, the manufacturing process system may be an assembly process system for cylindrical battery cells and may include process facilities that sequentially perform the processes of JRS, CCW, CIT, ISI, JRI, CRW, CBD, ABW, X-ray, ELF, CCR, CSZ, Washing, CTA, AIA, and IOU.

[0058] Meanwhile, the scope of the present invention is not limited to the type and name of the article to be manufactured and the manufacturing process system.

[0059] The simulator construction device may be equipped with modeling software, image authoring software, and image playback software, and can perform the simulator construction method described below using the installed software.

[0060] The simulator construction device can model each of the process equipment and the corresponding equipment object (S310).

[0061] Specifically, when N process equipment is included in a manufacturing process system, the simulator building device can model equipment objects corresponding to each of the N process equipment by digitizing the shape, specifications, and operation for each of the N process equipment. For example, as shown in FIG. 4, the simulator building device can generate equipment objects (10) corresponding to each of the process equipment included in a cylindrical battery cell assembly process system.

[0062] The simulator construction device can model transfer objects corresponding to each of the transfer units that are positioned between the equipment objects (10) and transfer an item to be manufactured. For example, the simulator construction device can generate transfer objects corresponding to each of the conveyors that connect the process equipment included in the assembly process system of a cylindrical battery cell.

[0063] In addition, the simulator construction device can model an article object corresponding to an article to be manufactured. For example, the simulator construction device can generate an article object corresponding to a battery cell that is to be manufactured in an assembly process system.

[0064] Afterward, the simulator building device can arrange equipment objects (10) in a virtual space predefined in two or three dimensions to correspond to a manufacturing process system (S320). Here, the simulator building device can arrange the equipment objects (10) sequentially according to the order in which the items to be manufactured are transported.

[0065] For example, the simulator construction device can arrange equipment objects corresponding to each of the process equipment included in the assembly process system of a cylindrical battery cell in a predetermined three-dimensional virtual space (100), as shown in FIG. 5, according to the transfer order of the battery cell.

[0066] In addition, the simulator construction device can arrange transfer objects in a virtual space to correspond with the manufacturing process system.

[0067] For example, the simulator construction device can model an assembly process system for cylindrical battery cells by connecting process equipment placed in a predefined three-dimensional virtual space (100) through transfer objects, as shown in FIG. 5.

[0068] Afterwards, the simulator construction device can individually generate process images that implement the operation of each of the equipment objects (10) (S330).

[0069] Here, the simulator construction device can reflect the movement of an item object being transported along a transport path defined for each of the equipment objects in each of the process images. For example, the simulator construction device can reflect the movement of a battery cell being moved along a battery cell transport path within the washing equipment in the process image for the washing equipment.

[0070] Additionally, the simulator construction device can individually generate transfer videos that implement the operation of each of the transfer objects. Here, the simulator construction device can reflect the operation of an item object being transported along a transfer path defined for each of the transfer objects in each of the transfer videos. For example, the simulator construction device can reflect the operation of a battery cell moving along a transfer path on a conveyor in a transfer video for a conveyor.

[0071] The simulator construction device can reflect the behavior of an item object being created at the point of the transfer path and disappearing at the end of the transfer path in each of the process images and transfer images. For example, in a process image for a washing facility, a battery cell can be created (appear) at the entry location of the washing facility and disappear at the discharge location of the washing facility.

[0072] Subsequently, the simulator construction device can independently play process videos corresponding to each of the equipment objects (S340). Here, the simulator construction device plays the nth process video for the nth equipment object, and after the playback of the nth process video is completed, it can play the n+1th process video for the n+1th equipment object connected to the nth equipment object.

[0073] In other words, process videos for each equipment object can be produced individually, and the process videos can be played sequentially according to the process order. Accordingly, if some process equipment is added, removed, or changed in the manufacturing process system, the simulator can be updated by adding, removing, or changing only the process videos for the relevant equipment.

[0074] In S340, the simulator construction device plays the nth process video for the nth equipment object, and when the playback of the nth process video is completed, it can play the nth transfer video for the nth transfer object connected to the nth equipment object. Subsequently, when the playback of the nth transfer video is completed, it can play the n+1th process video for the n+1th equipment object connected to the nth transfer object.

[0075] For example, referring to FIG. 6, the simulator construction device can play a first process video for a first facility object (10-1). In the first process video, an article object (battery cell) is created at the point in the transfer path (S1), is transferred along the transfer path, and can be destroyed at the end point of the transfer path (E1).

[0076] When the playback of the first process video is completed, the simulator construction device can play a first transfer video for a first transfer object (20-1) connected to the transfer path end point (E1) of the first equipment object (10-1). In the first transfer video, an article object (battery cell) is created at the transfer path start point (E1), is transferred along the transfer path, and can be destroyed at the transfer path end point (S2).

[0077] When the playback of the first transfer video is completed, the simulator construction device can play a second process video for a second facility object (10-2) connected to the transfer path end point (S2) of the first transfer object (20-1). In the second process video, an article object (battery cell) is created at the transfer path start point (S2), is transferred along the transfer path, and can be destroyed at the transfer path end point (E2).

[0078] When the playback of the second process video is completed, the simulator construction device can play a second transfer video for the second transfer object (20-2) connected to the transfer path end point (E2) of the second facility object (10-2). In the second transfer video, the article object (battery cell) is created at the transfer path start point (E2), is transferred along the transfer path, and can be destroyed at the transfer path end point (S3).

[0079] When the playback of the second transfer video is completed, the simulator construction device can play a third process video for a third facility object (10-3) connected to the transfer path end point (S3) of the second transfer object (20-2). In the third process video, the article object (battery cell) is created at the transfer path start point (S3), is transferred along the transfer path, and can be destroyed at the transfer path end point (E3).

[0080] According to an embodiment of the present invention, process images and transfer images for each of the equipment objects and transfer objects are individually produced and played sequentially, so that the simulator can be easily updated even if some process equipment is added, removed, or changed in the manufacturing process system. In addition, in each of the process images and transfer images, the product object is implemented to be created at the point of the transfer path and disappear at the end of the transfer path, so that the product object can be visualized as naturally being transferred along the transfer path of the manufacturing process system.
