Description

[Technical Field]

[0001] The present invention relates to a jig and an electrode manufacturing system including the jig.

[0002] This application claims priority based on Korean Patent Application No. 10-2022-0051692, filed on April 26, 2022, and the entire contents disclosed in the specification and drawings of that application are incorporated herein by reference. [Background technology]

[0003] To manufacture an electrode assembly for a secondary battery, a process of partially cutting an electrode can be applied. For example, laser cutting can be applied as a cutting method. A large-sized electrode substrate can be cut to produce multiple unit electrodes, or a desired shape can be produced by partially cutting specific positions of the electrode.

[0004] As such, as a device for laser cutting the electrode, for example, a drum type device or a flying type device can be applied.

[0005] Referring to Figure 1, a drum-type device for laser cutting is shown schematically. When using such a drum-type device, the drum directly supports the area of ​​the electrode where the laser is irradiated, which has the advantage of enabling stable cutting and preventing significant electrode vibration during travel. However, when using this type of device, the space required for installing the drum is necessarily relatively large, and since the laser is irradiated on the area directly supported by the drum, there is a risk of incomplete cutting and damage to the drum due to the irradiated laser.

[0006] Referring to FIG. 2, a flying-type apparatus for laser cutting is shown. The application of such a flying-type apparatus has the advantage that, compared to a drum-type apparatus, there are fewer spatial constraints and the electrode is more likely to be completely cut by laser irradiation. However, when this type of apparatus is applied, there is a possibility that the electrode may vibrate significantly as it travels. Such electrode vibration makes it difficult to adjust the focal length during laser irradiation, which may result in a deterioration in the quality of the manufactured electrode.

[0007] Therefore, there is a need to develop a jig that can minimize the above-mentioned shaking during electrode travel when processing an electrode, prevent the space occupied by the device from becoming too large, prevent damage to the device due to laser irradiation, and prevent incomplete cutting due to laser irradiation. Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been made in consideration of the above-mentioned problems, and one of its objects is to minimize the above-mentioned vibrations that occur when an electrode travels during machining of the electrode.

DETAILED DESCRIPTION OF THE INVENTION

[0038] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms and words used in this specification and claims should not be construed as being limited to their ordinary and dictionary meanings, but should be construed as meanings and concepts corresponding to the technical ideas of the present invention, based on the principle that the inventors themselves can appropriately define the concepts of terms in order to best describe the invention. Therefore, it should be understood that the configurations shown in the embodiments described in this specification are merely the most preferred embodiment of the present invention and do not represent the entire technical ideas of the present invention, and therefore various equivalents and modifications that can be substituted therefor may exist at the time of filing this application.

[0039] A jig (jg) 1 according to one embodiment of the present invention will be described with reference to Figures 3 to 5. Figure 3 is a conceptual diagram of the jig of the present invention, Figure 4 is a diagram showing an electrode cut by the jig and electrode manufacturing system of the present invention, and Figure 5 is a plan view showing the jig of the present invention.

[0040] 3 to 5, a jig 1 according to an embodiment of the present invention may be configured to support an electrode E that is moved along a first direction (a direction parallel to the X-axis). To ensure stable movement of the electrode E, at least one roller R may be provided along the movement direction of the electrode E. Such a roller R may guide the movement of the electrode E. The roller R may be a guide roller, or a drive roller that is rotatably connected to a drive device.

[0041] The jig 1 may be configured to support an electrode E including a coated portion C coated with an electrode active material and an uncoated portion NC not coated with an electrode active material. The jig 1 may include a first support part 10 and a second support part 20.

[0042] The first support portion 10 may be configured to support a region corresponding to the non-coating portion NC in the electrode E. The first support portion 10 may extend a predetermined length from one end of the second support portion 20 along a second direction (direction parallel to the Y-axis) substantially perpendicular to the first direction (direction parallel to the X-axis).

[0043] The extension length D1 of the first support member 10 in the second direction (see FIG. 8) may be equal to or greater than the distance from the boundary between the non-coating portion NC and the coated portion C to the end of the non-coating portion NC before laser cutting. That is, the extension width (length extending in a direction parallel to the Y-axis) of the first support member 10 may be equal to or greater than the height (extension length in the Y-axis direction) of the non-coating portion NC of the electrode E before cutting. This allows the first support member 10 to stably support the entire non-coating portion NC when the electrode E is transported. However, the first support member 10 of the present invention is not limited to supporting only the non-coating portion NC. That is, the first support member 10 of the present invention may be configured to support a portion of the coated portion C in addition to the non-coating portion NC.

[0044] The second support member 20 may be configured to support a region of the electrode E corresponding to the ground portion C. The extension length of the second support member 20 along the second direction (i.e., the direction parallel to the Y-axis) may be equal to or greater than the distance from the boundary between the non-coated portion NC and the ground portion C to the end of the ground portion C. That is, the extension width (length extending in the direction parallel to the Y-axis) of the second support member 20 may be equal to or greater than the height (extension length in the Y-axis direction) of the ground portion C of the electrode E. This allows the second support member 20 to stably support the entire ground portion C when the electrode E is transported. However, the second support member 20 of the present invention is not limited to supporting only the ground portion C. That is, the second support member 20 of the present invention may be configured to support a portion of the non-coated portion NC in addition to the ground portion C.

[0045] The first support part 10 may include a laser receiving part 11 formed at a position corresponding to an area where a laser L for cutting the non-coating portion NC is irradiated. The electrode E supported by the jig 1 of the present invention may be, for example, a double-sided coated electrode in which an electrode active material is coated on both sides of an electrode current collector.

[0046] As described above, the jig 1 of the present invention is provided with the laser storage section 11, so that when the laser L is irradiated onto the uncoated area NC to cut it into a desired pattern, the laser L can penetrate the uncoated area NC and reliably perform the cutting. If the laser storage section 11 is not provided, the surface of the electrode E opposite to the surface irradiated with the laser L is supported by the jig 1, and therefore the laser L may not be able to penetrate the electrode E, resulting in incomplete cutting.

[0047] In another aspect, this configuration of the present invention can prevent the surface of the jig 1 from being damaged by the laser L that penetrates the uncoated area NC, thereby extending the life of the device and preventing damage to the electrode E that passes through the surface of the damaged jig 1. Meanwhile, in the present invention, the target of laser cutting is not limited to the uncoated area NC alone. That is, in the present invention, the target of laser cutting can include a part of the coated area C in addition to the uncoated area NC.

[0048] Next, the shape of the laser housing 11 of the present invention will be described with reference to Fig. 5, Fig. 6, and Fig. 7. Fig. 6 is a diagram for explaining the process of irradiating a laser onto an electrode supported by the jig of the present invention to partially cut it, and is a diagram showing a cross section of the jig of Fig. 5 taken along X-X'. Fig. 7 is a diagram showing a jig to which a laser housing having a different structure is applied compared to the jig shown in Fig. 5.

[0049] 5 and 6, the laser receiving part 11 may be a hole penetrating the first support part 10 or a groove formed on the first support part 10 to a predetermined depth.

[0050] If the laser accommodating portion 11 is a hole, the jig 1 may not be damaged by the irradiated laser L. If the laser accommodating portion 11 is a groove, the irradiated laser L may damage the inner surface of the groove. However, even in such cases, there is no risk of the electrode E being damaged because the electrode E and the damaged portion of the jig 1 do not come into contact when the electrode E is transferred.

[0051] 7, the laser receiving part 11 may have a shape cut out inward from the outer end of the first support part 10 in the width direction (direction parallel to the Y axis). Such a cut-out shape of the laser receiving part 11 can be applied to both the case where the laser receiving part 11 is a groove and the case where the laser receiving part 11 is a hole.

[0052] 3 to 6, one surface of the jig 1 facing the electrode E may be configured to have a predetermined curvature along a direction parallel to a first direction, which is the direction of movement of the electrode E. The first support portion 10 and the second support portion 20 may have approximately the same curvature.

[0053] When one surface of the jig 1 has a curvature in this manner, the electrode E can be well adhered to the surface of the jig 1 as it passes through the jig 1. If the electrode E is not well adhered to the jig 1 during the plain portion NC cutting process by irradiating the laser L, it may be difficult to accurately irradiate the laser L at the desired position. In particular, if wrinkles occur in the electrode E, the laser L may not be focused, which may result in a decrease in cutting quality.

[0054] The radius of curvature of the surface of the jig 1 facing the electrode E can be in the range of approximately 400 to 800 mm. If the radius of curvature is too small, the focal length difference of the laser L at each cutting position when cutting the plain area NC by irradiating the laser L will be large, which may result in different cutting quality at each cutting position. Conversely, if the radius of curvature is too large, the electrode E will not adhere well to the surface of the jig 1, which may cause shaking during the transfer process.

[0055] As described above, when the surface of the jig 1 is configured to have a curvature, the laser receiving portion 11 may be formed at the highest position along the height direction of the jig 1 (direction parallel to the Z-axis). Meanwhile, FIG. 3 of the present invention shows only a case where the rollers R that guide the transfer of the electrode E are positioned below the electrode E, but the present invention is not limited thereto. The rollers R may be disposed above the electrode E on one and the other sides of the jig 1 along the transfer direction of the electrode E (direction parallel to the X-axis). In this case, the rollers R may be positioned below the highest position along the height direction of the jig 1 (direction parallel to the Z-axis). In this case, tension is generated in the electrode E by the rollers R, which allows the electrode E to be well adhered to the jig 1 at the position where the laser receiving portion 11 is formed.

[0056] Although not shown in the drawings, a coating layer may be formed on one surface of the jig 1 of the present invention that faces the electrode E. The coating layer may be configured to have abrasion resistance and / or friction-reducing properties. The surface of the jig 1 of the present invention may be damaged by repeated friction with the electrode E that occurs during the transfer of the electrode E. In another embodiment, the ground portion C of the electrode E may be damaged, such as by the electrode active material being detached, due to the frictional force that occurs during the transfer of the electrode E.

[0057] When a coating layer having wear resistance and / or friction reducing properties is at least partially formed on the surface of the jig 1, damage to the electrode E and / or the jig 1 due to such friction can be minimized.

[0058] Next, the relationship between the extension width D1 of the first support portion 10 of the present invention, the height D2 of the uncoated portion NC after laser cutting, the extension width D3 of the laser storage portion 11, and the cutout depth D4 of the uncoated portion NC by laser cutting will be described with reference to Figures 8 and 9. Figures 8 and 9 are views showing the jig and electrode of the present invention as viewed from below the jig.

[0059] 8 and 9, the extension width D1 of the first support portion 10 can be determined by considering the overall height (length extending in a direction parallel to the Y-axis) of the uncoated portion NC before laser cutting and the height D2 (length extending in a direction parallel to the Y-axis) of the uncoated portion NC after laser cutting. As described above, the extension width D1 of the first support portion 10 can be formed to be approximately the same as or greater than the overall height of the uncoated portion NC before laser cutting, taking into consideration the running stability of the electrode E.

[0060] Meanwhile, the extension width D3 (extension length along the direction parallel to the Y-axis) of the laser receiving portion 11 can be determined in consideration of the depth D4 of the cutout of the non-coating portion NC by laser cutting. Because the electrode E moves only in the first direction (direction parallel to the X-axis), the extension width D3 of the laser receiving portion 11 can be formed to be greater than the depth of the cutout of the non-coating portion NC by laser cutting. When this condition is met, the process of cutting the non-coating portion NC passing through the laser receiving portion 11 into a desired pattern can be smoothly performed.

[0061] Next, the floating function of the jig 1 of the present invention will be described with reference to Fig. 10 to Fig. 12. Fig. 10 is a diagram showing an electrode floating by the jig of the present invention, Fig. 11 is a diagram showing the structure of a second support part for floating the electrode, and Fig. 12 is a diagram showing an air blower for floating the electrode.

[0062] 10 to 12, the second support 20 of the present invention may be configured to float the electrode E on the second support 20. In this case, as shown in FIG. 10, the electrode E passing through the jig 1 may be transported with the ground portion C floating on the second support 20 without contacting the jig 1. That is, the second support 20 may support the ground portion C by floating it using air pressure, for example, without directly contacting it. When the ground portion C is configured not to come into contact with the second support 20 in this way, damage or detachment of the electrode active material due to friction occurring during the transport of the electrode E can be prevented.

[0063] For example, the second support part 20 may include an air floating hole 21. A plurality of air floating holes 21 may be provided. The jig 1 may include an air blower 30 provided at a position corresponding to the air floating hole 21. The air blower 30 may be configured to apply pressure to the ground portion C through the air floating hole 21 for floating. As a result, the ground portion C can be maintained at a small distance from the jig 1 during the transfer of the electrode E. In contrast, the non-coated portion NC of the electrode E can pass through the area where the laser receiving part 11 is formed while being in close contact with the first support part 10, thereby ensuring smooth laser cutting.

[0064] Next, the coating layer 12 formed on the first support part 10 will be described with reference to Fig. 13. Fig. 13 is a diagram showing anti-friction structures formed on each of the first support part and the second support part.

[0065] 13, the first support part 10 may include a coating layer 12 formed on one surface facing the electrode E. When the second support part 20 is configured to float the electrode E, the coating layer 12 may be formed only on the first support part 10. The coating layer 12 may be configured to have abrasion resistance and / or friction reduction. The uncoated portion NC of the electrode E may be transferred in close contact with the first support part 10 for smooth laser cutting. Therefore, when the coating layer 12 configured to have such abrasion resistance and / or friction reduction is formed on the first support part 10, damage to the electrode E and / or the jig 1 due to friction between the uncoated portion NC and the first support part 10 can be minimized.

[0066] Next, the foreign matter discharge function of the jig 1 of the present invention will be described with reference to Figures 14 and 15. Figure 14 is a diagram showing a foreign matter discharge portion formed in the jig of the present invention, and Figure 15 is a diagram showing a suction portion provided in the jig of the present invention.

[0067] 14, the first support part 10 may include foreign matter discharge parts 13 formed on both sides of the laser receiving part 11 along a first direction (a direction parallel to the X-axis). The foreign matter discharge parts 13 may include a plurality of foreign matter discharge holes penetrating the first support part 10. When the first support part 10 includes the foreign matter discharge parts 13, it is possible to minimize a phenomenon in which foreign matter, such as molten fumes generated by laser cutting, accumulates around the laser receiving part 11 and increases the friction of the electrode E during running.

[0068] 15 together with FIG. 14, the jig 1 may include a suction unit 40 provided in a region corresponding to the foreign matter discharge unit 13. The suction unit 40 may be provided, for example, inside the jig 1. The suction unit 40 allows foreign matter, such as molten fumes generated by laser cutting, to pass through the foreign matter discharge unit 13 and be discharged to the outside of the jig 1 via the suction unit 40. When the jig 1 of the present invention includes such a suction unit 40, it is possible to more efficiently prevent the molten fumes from adhering to the periphery of the laser accommodation unit 11, thereby improving the quality of the electrode E and / or extending the life of the jig 1.

[0069] Next, the electrode manufacturing system of the present invention will be described with reference to Figures 16 and 17. Figure 16 is a conceptual diagram of the electrode manufacturing system of the present invention, and Figure 17 is a diagram exemplarily showing the operation of the laser irradiation device of the present invention for forming a cutting line on an electrode.

[0070] 16, an electrode manufacturing system 3 of the present invention may include the jig 1 of the present invention as described above, and a laser irradiation device 2 provided at a position corresponding to the laser receiving portion 11 formed in the jig 1. The electrode manufacturing system 3 may include rollers R for stable transfer of the electrode E transferred along a first direction (a direction parallel to the X-axis). The rollers R may be configured to guide the transfer of the electrode E or to provide power for the transfer of the electrode E.

[0071] Referring to Figure 17 together with Figure 16, the laser irradiation device 2 can be configured to partially cut the uncoated portion NC of the electrode E and form a repeated cutout pattern on the uncoated portion NC along a first direction (a direction parallel to the X-axis).

[0072] For example, when the electrode E is moved along the direction A, the laser irradiation point of the laser irradiation device 2 may move sequentially along paths L1, L2, L3, and L4, repeatedly tracing a substantially ribbon-like shape. Movement along path L1 may be in the same direction as the direction A. Movement along path L2 may be in the opposite direction to the direction A and toward the second support unit 20. Movement along path L3 may be in the same direction as the direction A. The movement distance along path L3 may be shorter than the movement distance along path L1. Movement along path L4 may be in the opposite direction to the direction A and away from the second support unit 20. The movement distance along path L4 may be substantially the same as the movement distance along path L2.

[0073] As the laser irradiation point of the laser irradiation device 2 moves sequentially along these paths L1, L2, L3, and L4, a cutting line CL having a specific pattern can be formed on the electrode E moving along direction A. A first cutting line C1 can be formed along path L1 of movement of the laser irradiation point. A second cutting line C2 can be formed along path L2 of movement of the laser irradiation point. A third cutting line C3 can be formed along path L3 of movement of the laser irradiation point. A fourth cutting line C4 can be formed along path L4 of movement of the laser irradiation point. Cut segments CS formed along such cutting lines CL can be removed, for example, by a separately provided suction device.

[0074] If the traveling speed of the electrode E along direction A is faster than the speed at which the irradiation point of the laser irradiation device 2 moves, the movement of the laser irradiation point will cut the plain area NC, resulting in the formation of an approximately rectangular segment of the plain area with a longer bottom edge and a shorter top edge.

[0075] However, the above-mentioned traveling direction and speed of the electrode E and the moving direction and speed of the laser irradiation point are merely examples, and the present invention is not limited thereto.

[0076] Although the present invention has been described above using limited embodiments and drawings, the present invention is not limited thereto, and it goes without saying that a person having ordinary knowledge in the technical field to which the present invention pertains can make various modifications and variations within the technical spirit of the present invention and the equivalent scope of the following claims.
