Description

This invention relates to a system configured to generate a roll map representing a lot, which is a unit of wound electrode sheets, and to a method for generating a roll map. This application claims the interests of Korean Application No. 10-2023-0092804, filed on 18 July 2023, which is herein by reference in its entirety. Unlike primary batteries, rechargeable batteries can be charged and discharged multiple times. Rechargeable batteries are widely used as an energy source for a variety of wireless devices, such as handsets, laptops, and wireless vacuum cleaners. In recent years, improvements in energy density and economies of scale have dramatically reduced the manufacturing cost per unit capacity of rechargeable batteries. As the driving range of battery electric vehicles (BEVs) increases to levels comparable to those of fuel-powered vehicles, the primary application of rechargeable batteries is shifting from mobile devices to mobility. Secondary batteries are manufactured through electrode processing, assembly processing, and activation processing. Of these, the electrode processing is the most crucial process in determining the yield and performance of the battery cells. Electrode processing can include coating processing, roll pressing processing, and slitting processing. In the coating process, active material and insulating material can be applied to the surface of the current collector. In the roll pressing process, the electrodes can be pressed by pressure rolls. Roll pressing processing can determine the density, performance, and surface quality of the electrodes. In the slitting process, the electrodes can be cut into multiple electrodes depending on the design of the battery cell. An exemplary embodiment of a role map generation system is shown.This is a plan view showing the electrode sheet portion.This is a flowchart showing a role map generation method according to an exemplary embodiment.An exemplary embodiment of a role map generation system is shown. Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. Before that, however, terms and words used herein and in the claims should not be construed to be limited to their usual or dictionary meanings, but rather to meanings and concepts consistent with the technical idea of the present invention, based on the principle that an inventor may appropriately define the concepts of terms in order to best describe his own invention. Therefore, the embodiments described herein and the configurations shown in the drawings represent only one of the most preferred embodiments of the present invention and do not represent the entire technical concept of the invention; thus, there may be a variety of equivalents and modifications that can substitute for them at the time of filing. Furthermore, in describing the present invention, if it is determined that a specific description of a related known configuration or function would obscure the gist of the invention, such detailed description will be omitted. Embodiments of the present invention are provided to more fully explain the invention to a person of ordinary skill; therefore, the shapes and sizes of components in the drawings may be exaggerated, omitted, or shown schematically for the sake of clarity. Accordingly, the sizes and proportions of each component do not fully reflect their actual sizes and proportions. (First embodiment: apparatus, second embodiment: method) Figure 1 shows a role map generation system 100 according to an exemplary embodiment. Figure 2 is a plan view showing a portion of the electrode sheet ES. Referring to Figures 1 and 2, the roll map generation system 100 may include an unwinder 111, a rewinder 113, a processing device 115, a first rotary encoder 121, a second rotary encoder 123, a measuring instrument 130, a first controller 141, a second controller 143, communication servers 150 and 160, and servers 170, 180, and 190. The roll map generation system 100 can be configured to generate a roll map containing data related to the electrode sheet ES. The roll map can represent the electrode sheet ES based on coordinates indicating its position on the electrode sheet ES. Processes for manufacturing a secondary battery can be performed on the electrode sheet ES. The roll map can represent the history of processes performed on the electrode sheet ES and may include data related to the coordinates. This allows the roll map to enable feedback, feedforwarding, and tracking of the secondary battery manufacturing process, as described later. The first electrode roll ER1, after the preceding process, can be loaded onto an unwinder 111. The unwinder 111 can be configured to unwind the electrode sheet ES from the first electrode roll ER1. A rewinder 113 can be configured to wind the electrode sheet ES to form the second electrode roll ER2. This allows the electrode sheet ES to move between the unwinder 111 and the rewinder 1
