[0039] The expression one element is 'coupled' or 'connected' to another element should be understood to mean that elements can be directly coupled or connected to each other, and that elements can be indirectly coupled or connected through a connecting member.

[0040] Figure 1 is a schematic front view of an electrode production device according to an embodiment of the present invention, from which a suction member has been omitted. Figure 2 is a drawing illustrating a gauge member in an electrode production device according to an embodiment of the present invention, in which foreign matter is sliding along a third slope portion. Figure 3 is a drawing illustrating a state in which the foreign matter moves along the third slope portion in Figure 2 and then accumulates in a foreign matter accumulation portion. Figure 4 is an enlarged view. Petition 870250071614, dated 08 / 14 / 2025, page 16 / 45 8 / 16 of part B in Figure 3 and Figure 5 is a drawing illustrating a suction member when viewed in the direction of arrow A in Figure 2.

[0041] Referring to Figure 1, an electrode production device 10, according to one embodiment of the present invention, refers to a device for producing an electrode (positive electrode or negative electrode) carrying an electrode sheet 600 on which a coating layer is formed with an active electrode material. The electrode may encompass either a wet electrode or a dry electrode.

[0042] For example, the wet electrode is manufactured by a process of applying a paste-like electrode mixture, including a solvent, onto the surface of an electrode substrate, such as a 600 electrode sheet, to form a coating layer and then drying the coating layer.

[0043] Furthermore, the dry electrode is manufactured by means of a coating layer forming process, pressing a powdered electrode mixture (powder mixture), which does not contain a solvent, onto the surface of a 600 electrode sheet. That is, the electrode mixture is mixed without a liquid medium, such as a solvent or dispersing medium, and then the powdered electrode mixture is pressed while passing through a rolling mill, thereby manufacturing the electrode.

[0044] Here, electrode foil 600 may include a coated portion that has a coating layer of electrode active material formed on the surface and an uncoated portion (e.g., both ends of electrode foil 600) that does not have a coating layer of electrode active material.

[0045] The electrode production device 10 according to one embodiment of the present invention refers to a device capable of preventing foreign matter 700 from adhering to a member of a gauge. Petition 870250071614, dated 08 / 14 / 2025, p. 17 / 45 9 / 16 to 300 which supports the 600 electrode sheet when the 600 electrode sheet is cut by a laser while being transported. From here on, the device will be described in detail.

[0046] Referring to Figure 1, the electrode production device 10 according to one embodiment of the present invention can be configured to include a transport member 100, a laser member 200 and a jig member 300.

[0047] The transport member 100 carries an electrode sheet 600 coated with an active electrode material. The transport member 100 can be configured in various forms and may include, for example, a plurality of rollers to transport the electrode sheet 600 in a roller-to-roll mode. Although the transport member 100 is not limited to this, an embodiment in which the transport member 100 includes a plurality of rollers will be described below for convenience of explanation.

[0048] Referring to Figure 1, the transport member 100 may include a first transfer roller 110 and a second transfer roller 120. Here, the first transfer roller 110 and the second transfer roller 120 may be arranged in various positions and, for example, as shown in Figure 1, the first transfer roller 110 may be arranged on the upper side and the second transfer roller 120 may be arranged on the lower side.

[0049] In this embodiment, the electrode sheet 600 is transported from the first transfer roller 110 on the upper side to the second transfer roller 120 on the lower side. That is, the electrode sheet 600 moves from the upper side to the lower side by the first transfer roller 110 and the second transfer roller 120.

[0050] Referring to Figure 1, laser member 200 is configured to irradiate electrode sheet 600 with a laser. Laser member 200 may include various types of laser equipment. Referring to Fi Petition 870250071614, dated 08 / 14 / 2025, p. 18 / 45 10 / 16 Fig. 1, when the electrode sheet 600 moves from the top side to the bottom side by the first transfer roller 110 and the second transfer roller 120, the laser member 200 can be configured to irradiate the electrode sheet 600 with a laser in a horizontal direction as shown in Figure 1.

[0051] Referring to Figure 1, the jig member 300 contacts the electrode sheet 600 and supports the electrode sheet 600. The jig member 300 can prevent vibration or shaking of the electrode sheet 600 when the electrode sheet 600 is cut by the laser member 200, thereby preventing cutting defects such as irregular cutting or cutting the wrong part instead of a predetermined part when cutting the electrode sheet 600 by the laser member 200.

[0052] In addition, a foreign matter adhesion prevention portion 350 is formed in the template member 300. The foreign matter adhesion prevention portion 350 will be described later.

[0053] The template member 300 can be configured in various modes and can include, for example, a first part 310, a second part 320, and a third part 330. Here, the first part 310, the second part 320, and the third part 330 are temporarily divided in the template member 300 only for convenience of explanation, and the division of the first part 310, the second part 320, and the third part 330 is not absolute. For example, the first part 310, the second part 320, and the third part 330 can be manufactured separately from each other and then combined to form the template member 300, or the first part 310, the second part 320, and the third part 330 can be integrally formed in the manufacturing step.

[0054] Referring to Figure 1 and Figure 2, the first part 310 is dis Petition 870250071614, dated 08 / 14 / 2025, page 19 / 45 11 / 16 placed in the vertical direction. Furthermore, an internal groove 311 is formed in the first part 310. Here, the internal groove 311 can be formed on the entire first part 310, the second part 320, and the third part 330; it can be formed on any one of the first part 310, the second part 320, and the third part 330; or it can be formed on two of the first part 310, the second part 320, and the third part 330. That is, the internal groove 311 can be formed on one or more of the first part 310, the second part 320, and the third part 330.

[0055] The second part 320 is coupled to the first part 310 on the upper side of the third part 330 in Figure 2. Furthermore, the third part 330 is coupled to the first part 310 on the lower side of the second part 320 in Figure 2.

[0056] That is, in Figure 2, the second part 320 is arranged on the upper side and the third part 330 is arranged on the lower side, and these are coupled to the first part 310, respectively.

[0057] Referring to Figure 2, the second part 320 may include a second part main portion 321 and a second part protrusion 322. The second part main portion 321 is coupled to the first part 310. That is, the second part main portion 321 is coupled to the first part 310 on the upper side of a third part main portion 331. Furthermore, the second part protrusion 322 projects downward from the second part main portion 321.

[0058] Referring back to Figure 2, the third part 330 may include a third part main portion 331 and a third part protrusion 332. The third part main portion 331 is coupled to the first part 310. That is, the third part main portion 331 is coupled to the first part 310 on the underside of the second part main portion 321. Furthermore, the third part protrusion 332 projects upward from the third part main portion 331. Petition 870250071614, dated 08 / 14 / 2025, page 20 / 45 12 / 16

[0059] Here, a gap 340 can be formed between the second-part protrusion 322 and the third-part protrusion 332, and the laser member 200 can irradiate the laser into the gap 340 between the second-part protrusion 322 and the third-part protrusion 332.

[0060] Furthermore, referring to Figure 4, the foreign matter adhesion prevention portion 350 can be configured as a first slope portion 351 formed at the end of the second-part protrusion 322. Alternatively, the foreign matter adhesion prevention portion 350 can be configured as a second slope portion 352 formed at the end of the third-part protrusion 332.

[0061] That is, the foreign matter 700 generated when the electrode sheet 600 is cut by a laser can adhere to the jig member 300. Specifically, since the second-part protrusion 322 or the third-part protrusion 332, which projects from the jig member 300, is in direct contact with the electrode sheet 600, if the foreign matter 700 adheres to the second-part protrusion 322 or the third-part protrusion 332, defects may be caused in the electrode sheet 600.

[0062] The electrode production device 10 according to one embodiment of the present invention has a first tilting portion 351 (foreign matter adhesion prevention portion 350) formed at the end of the second part protrusion 322 or a second tilting portion 352 (foreign matter adhesion prevention portion 350) formed at the end of the third part protrusion 332, thereby preventing the adhesion of foreign matter 700.

[0063] That is, in the case where the first portion of slope 351 is formed in the second part protrusion 322 or the second portion of slope 352 is formed in the third part protrusion 332, the area of Petition 870250071614, dated 08 / 14 / 2025, page 21 / 45 13 / 16 second part protrusion 322 is reduced compared to the case where the first inclination portion 351 is not formed, and the area of ​​the third part protrusion 332 is also reduced compared to the case where the second inclination portion 352 is not formed, making it difficult for foreign matter 700 to adhere.

[0064] That is, if the first slope portion 351 or the second slope portion 352 is formed too sharply, it will be difficult for the foreign matter 700 to adhere to the first slope portion 351 or the second slope portion 352, so that the adhesion of the foreign matter 700 will be difficult. However, the sharpness of the first slope portion 351 or the second slope portion 352 can be determined in consideration of the degree to which the electrode sheet 600 is not damaged.

[0065] In addition, there is an effect of preventing foreign matter 700 from adhering to the gauge member 300, thereby avoiding electrode defects and ultimately improving electrode quality.

[0066] Meanwhile, the first slope portion 351 can be formed in several ways. For example, the first slope portion 351 can be formed to face the outside of the second part protrusion 322, it can be formed to face the inside of the second part protrusion 322, or it can be formed entirely along the perimeter of the second part protrusion 322.

[0067] Furthermore, similar to the first slope portion 351, the second slope portion 352 can also be formed in various ways. For example, the second slope portion 352 can be formed to face the outside of the third-part protrusion 332, it can be formed to face the inside of the third-part protrusion 332, or it can be formed entirely on the perimeter of the third-part protrusion 332. Petition 870250071614, dated 08 / 14 / 2025, page 22 / 45 14 / 16

[0068] That is, the slope of the first slope portion 351 and the second slope portion 352 can be formed in any direction.

[0069] Referring to Figure 2, in another embodiment, the foreign matter adhesion prevention portion 350 can be configured as a third tilting portion 353 formed in the inner groove 311, so that the foreign matter slides down.

[0070] For example, the third inclination portion 353 can be formed in the inner groove 311 of the jig member 300, so that the foreign matter 700 slides down. Here, the third inclination portion 353 can be formed to be inclined downwards from the first part 310 towards the third part 330.

[0071] Referring to both Figure 2 and Figure 3, the third inclination portion 353 formed in the inner groove 311 of the template member 300 causes the foreign matter 700 introduced into the inner groove 311 to slide down, so that the foreign matter 700 can accumulate in a predetermined position.

[0072] That is, the third inclination portion 353 can prevent foreign matter 700 from adhering to the inner groove 311 of the jig member 300.

[0073] Furthermore, for example, a foreign matter accumulation portion 360 can be formed at the end of the third slope portion 353, so that the foreign matter 700 sliding along the third slope portion 353 is collected in the foreign matter accumulation portion 360 (see Figure 3). As described above, when the foreign matter 700 is collected in the foreign matter accumulation portion 360, it is easy to dispose of the foreign matter 700.

[0074] Referring to Figure 5, a suction member 400 is provided for sucking up foreign matter 700 and can be arranged, for example, Petition 870250071614, dated 08 / 14 / 2025, page 23 / 45 15 / 16 near the foreign matter accumulation portion 360. The suction member 400 can be configured in various modes and can include, for example, various suction devices (e.g., a vacuum suction device).

[0075] Figure 6 is a drawing that schematically illustrates the configuration of a battery pack, which includes a battery cell that has an electrode produced using an electrode production device according to an embodiment of the present invention.

[0076] Referring to Figure 6, a battery set 30 according to an embodiment of the present invention may include one or more battery cells 20. Here, the battery cell 20 includes an electrode produced using electrode production devices 10 according to the respective embodiments of the present invention described above.

[0077] In addition, the battery pack 30 may also include a housing 31 for storing the battery cell 20 and various devices for controlling the charging and discharging of the battery cell 20, such as a BMS, a current sensor, a fuse or similar.

[0078] Meanwhile, although the cylindrical battery cell is provided within the assembly housing 31 in Figure 6, the present invention is not limited to this, and the battery cell 20 may include a pouch-type battery cell or a prismatic battery cell.

[0079] Figure 7 is a drawing that illustrates a vehicle that includes the battery pack of Figure 6.

[0080] Referring to Figure 7, a vehicle 40, according to one embodiment of the present invention, may include one or more battery cells 20 or battery packs 30, which include electrodes produced Petition 870250071614, dated 08 / 14 / 2025, page 24 / 45 16 / 16 of which utilize electrode production devices 10 according to the respective embodiments of the present invention. Here, vehicle 40 includes various vehicles designed to use electricity, such as electric vehicles or hybrid vehicles.

[0081] Meanwhile, although terms indicating directions such as up, down, left and right are used in this descriptive report, it is obvious to those skilled in the art that these terms are only for convenience of explanation and may vary depending on the location of the target object or the location of the observer.

[0082] As described above, although the present invention has been described with reference to limited embodiments and designs, the present invention is not limited thereto, and various modifications and variations are possible within the technical idea of ​​the present invention and the scope of equivalence of the claims to be described below by those skilled in the art to which the present invention pertains.
