Description

Technical Field

[0001] The present disclosure relates to an electrode manufacturing device, and more particularly to a slitting device in the electrode manufacturing device.

[0002] This application claims priority to Korean Patent Application No. 10-2023-0073808 filed in Korea on June 8, 2023, the disclosure of which is incorporated herein by reference. Background Art

[0003] Secondary batteries have high applicability depending on product groups and electrical characteristics such as high energy density, and are therefore generally applied not only to portable devices but also to electric vehicles (EVs) or hybrid electric vehicles (HEVs) driven by power supplies. Such secondary batteries are gaining attention as a new energy source to improve eco-friendliness and energy efficiency because they have the main advantage of not only significantly reducing the use of fossil fuels but also having no byproducts generated by the use of energy.

[0004] Currently widely used secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, nickel-zinc batteries, etc. The operating voltage of a unit secondary battery cell (i.e., a unit battery cell) is about 2.5V to 4.5V. Therefore, if a higher output voltage is required, a plurality of battery cells can be connected in series to configure a battery pack. In addition, depending on the required charge / discharge capacity of the battery pack, a plurality of battery cells can be connected in parallel to configure a battery pack. Therefore, the number of battery cells included in the battery pack can be set differently according to the required output voltage or the required charge / discharge capacity.

[0005] Meanwhile, in the process of manufacturing a secondary battery, the electrode may be cut. At this time, when the electrode is cut, foreign matter such as powder of the foil constituting the electrode or electrode powder may be generated. As a result, foreign matter such as powder may fly and adhere to the electrode surface, thereby contaminating the electrode. After the battery is completed, the electrode powder and the foil powder deposited on the electrode surface may cause performance degradation and safety problems. Summary of the invention

[0040] The preferred embodiments of the present disclosure are described in detail below in conjunction with the accompanying drawings. Before the description, it should be understood that the terms used in the specification and the appended claims should not be interpreted as limited to the general and dictionary meanings, but are interpreted based on the principle that the inventor is allowed to appropriately define the terms for the best interpretation, based on the meanings and concepts corresponding to the technical aspects of the present disclosure.

[0041] Therefore, the descriptions presented herein are merely preferred examples for illustrative purposes, and are not intended to limit the scope of the present disclosure, and it should be appreciated that other equivalents and modifications may be made thereto without departing from the scope of the present disclosure.

[0042] Additionally, to help understand the present disclosure, the drawings are not drawn to scale and the sizes of some components may be exaggerated.

[0043] Figure 1 1 is a diagram for explaining an electrode manufacturing apparatus 1 according to an embodiment of the present disclosure.

[0044] Reference Figure 1 , the electrode manufacturing apparatus 1 according to an embodiment of the present disclosure includes a slitting roller 10 and at least one support 20. The electrode manufacturing apparatus 1 may further include a frame 30 and / or a filtering device.

[0045] The slitting roller 10 and the support 20 may be devices included in the slitting process during the electrode manufacturing process. For example, the electrode manufacturing process may include a mixing process for measuring and mixing the active materials required for manufacturing the positive electrode and the negative electrode, a coating process for applying the mixed active materials to the electrode E, and a rolling process for passing the coated electrode E between rollers, and a cutting process for slitting the rolled electrode E according to the battery size. The electrode manufacturing process may also include, for example, an electrode E drying process. Here, the slitting roller 10 and the support 20 may be included in the slitting process among a plurality of processes.

[0046] Figure 2 It is used to illustrate Figure 1 FIG. 1 is a diagram of a slitting roller 10 included in an electrode manufacturing apparatus 1 .

[0047] Reference Figure 2, the slitting roller 10 may be configured to have a substantially cylindrical shape. At this time, the longitudinal axis of the cylinder may be perpendicular to the moving direction of the electrode E. That is, the side surface of the cylindrical slitting roller 10 may be arranged to face the electrode E.

[0048] The slitting roller 10 may include at least one knife 11 for cutting the electrode E. In particular, the slitting roller 10 may include at least one knife 11 disposed on a side surface thereof to cut the electrode E. For example, the knife 11 may be configured to surround the side surface of the slitting roller 10. That is, the central axis of the knife 11 and the central axis of the slitting roller 10 may be the same. Here, the knife 11 may be disposed parallel to the moving direction of the electrode E. Therefore, the electrode E may be cut along a line parallel to the moving direction.

[0049] The slitting roller 10 may include a plurality of knives 11. At this time, the spacing between the knives 11 may vary according to the size specifications of a specific battery. In addition, the knives 11 may be configured to be replaceable. For example, if the knives 11 are used for a long time, the blades may be worn. At this time, the worn blades may be replaced with unworn blades.

[0050] The slitting roller 10 may be provided on one side of the electrode E. In this case, a plate capable of supporting the knife 11 and the electrode E may be provided on the opposite side of the slitting roller 10. Therefore, the electrode E between the knife 11 and the plate provided on the slitting roller 10 may be smoothly cut.

[0051] In another embodiment, the slitting rollers 10 may be provided on both sides of the electrode E. When the slitting rollers 10 are provided on both sides of the electrode E, the knives 11 provided on each slitting roller 10 may be provided at the same position. Therefore, the electrode E inserted between the knives 11 may be smoothly cut.

[0052] Meanwhile, the electrode E may be cut by the knife 11 as described above. At this time, when the electrode E is cut, foreign matter such as powder of the foil constituting the electrode E or electrode powder may be generated. Therefore, foreign matter such as powder may fly and adhere to the surface of the electrode E and contaminate the electrode E. In this way, after the battery is completed, the electrode powder and the foil powder deposited on the surface of the electrode E may cause performance degradation and safety problems. Figure 3 and Figure 4 This will be described in detail to explain the conventional electrode manufacturing apparatus 1.

[0053] Figure 3 is a diagram for explaining a conventional electrode manufacturing apparatus, and Figure 4 is a diagram for explaining another type of conventional electrode manufacturing equipment.

[0054] refer to Figure 3, a conventional electrode manufacturing device includes a slitting roller, and the slitting roller includes a knife arranged around the slitting roller. The conventional electrode manufacturing device includes a bracket, which surrounds a portion of the knife at a position facing the knife. A suction device and a blowing device are provided on the bracket, and the suction device and the blowing device are components for discharging foreign matter. According to this structure, air is discharged from the blowing device to move foreign matter, and the moved foreign matter is sucked by the suction device, so that the foreign matter is removed. However, according to this structure, since the bracket is arranged adjacent to the knife, it is possible to remove foreign matter adhering to the knife, but it is difficult to remove foreign matter that has been scattered and deposited on the electrode E.

[0055] Reference Figure 4 Another conventional electrode manufacturing apparatus includes a slitting roller having a knife, and includes a suction device and a blowing device located downstream in the moving direction of the electrode E and spaced apart from the slitting roller by a predetermined distance. More specifically, along the moving direction of the electrode E, the slitting roller, the blowing device, and the suction device are alternately arranged. According to this structure, foreign matter generated at the cutting portion of the electrode E may first be scattered due to the blowing device and then removed by the suction device. However, according to this structure, since the blowing device and the suction device are located on the same side relative to the electrode E and spaced apart from each other by a predetermined distance, electrode vibration may occur. That is, as Figure 4 As shown, since the blowing device applies downward pressure to the electrode E and the suction device pulls the electrode E upward, there is a possibility that the electrode E is bent into a flat S shape. Therefore, the inventors of the present disclosure have conceived an electrode manufacturing apparatus to solve all these problems, which will be referred to below. Figures 5 to 11 Detailed description.

[0056] Figure 5 It is shown Figure 1 A side view of an electrode manufacturing apparatus 1, and Figure 6 It is used to describe the Figure 1 FIG. 2 is a diagram of a support 20 in an electrode manufacturing apparatus 1 .

[0057] Reference again Figure 1 , the support 20 may be located downstream of the moving direction of the electrode E, and the electrode E is spaced apart from the slitting roller 10 by a predetermined distance. Figure 1 , the electrode E may enter the support 20 after passing through the slitting roller 10. In other words, the electrode E may enter the support 20 after being cut at the slitting roller 10.

[0058] refer to Figure 5 and Figure 6 , the support 20 may include a plurality of micropores H. The plurality of micropores H may be arranged to be spaced apart from each other by a predetermined distance. Figure 6 As shown, the gaps between the plurality of microholes H can be very small. Figure 1, the gap between one microhole H and an adjacent microhole H may be smaller than the gap between one knife 11 and an adjacent knife 11 .

[0059] At this time, foreign matters generated by cutting the electrode E in the slitting roller 10 may be removed through the micropores H. In other words, the support 20 may remove foreign matters adhered to the electrode E passing through the support 20 .

[0060] Thus, according to the structure in which the electrode E passes through the support 20, not only foreign matter adhering to the knife 11 but also foreign matter adhering to the electrode E itself can be effectively removed. In addition, according to the structure in which the support 20 has a plurality of micropores H, a tiny airflow is formed between the electrode E and the support 20, thereby preventing the electrode from vibrating. That is, as Figure 5 As shown, a minute air layer is formed in the region adjacent to the electrode E, thereby preventing the electrode E from sagging or bending. As a result, wrinkles that may appear on the electrode E can be flattened. In addition, since the support 20 covers the electrode E, the above structure can facilitate the removal of foreign matter.

[0061] Reference again Figure 5 , the micro holes H may include a blowing hole BH for discharging air and a suction hole SH for sucking air.

[0062] The blowing hole BH may discharge air to disperse foreign matter. Preferably, the blowing hole BH may guide foreign matter toward the suction hole SH. The suction hole SH may absorb the scattered foreign matter. The micropores H may be the blowing holes BH or the suction holes SH. However, the case where all the micropores H are the blowing holes BH or all the micropores H are the suction holes SH may be excluded from the scope of the present disclosure. Preferably, the micropores H included in the bracket 20 of the present disclosure may include the blowing holes BH and the suction holes SH.

[0063] Thus, according to the structure of the bracket 20, the blowing hole BH and the suction hole SH are included at the same time, and the distance between the blowing hole BH and the suction hole SH is reduced, so that a small airflow can be formed. Therefore, the electrode can be prevented from vibrating. That is, as Figure 5 As shown, since a minute air layer is formed in the region adjacent to the electrode E, it is possible to prevent the electrode E from sagging or bending. As a result, wrinkles that may appear on the electrode E can be flattened.

[0064] In one aspect of the present disclosure, referring to Figure 5 , the electrode manufacturing apparatus 1 may include: an air injector 50 connected to the blowing hole BH through a pipe to discharge air; and an air sucker 40 connected to the suction hole SH through a pipe to suck air.

[0065] For example, the air injector 50 and / or the air inhaler 40 may include an air pump and / or an air pressurizer. The air injector 50 and / or the air inhaler 40 may be connected to the bracket 20. For example, the air injector 50 may be connected to the blowing hole BH provided in the bracket 20 through a pipeline so that air can be discharged through the blowing hole BH. Meanwhile, the air inhaler 40 may be connected to the suction hole SH provided in the bracket 20 through a pipeline so that air can be sucked through the suction hole SH.

[0066] In another aspect of the present disclosure, the support 20 may include an upper support 21 located above the electrode E and a lower support 22 located below the electrode E.

[0067] For example, refer to Figure 1 and Figure 5 The electrode manufacturing device 1 may include an upper support 21 located above the electrode E and a lower support 22 located below the electrode E. The spacing distance between the upper support 21 and the electrode E may be approximately equal to the spacing distance between the lower support 22 and the electrode E.

[0068] According to this structure, foreign matter can be sucked and removed from the upper and lower parts of the electrode E at the same time. For example, in an embodiment in which the slitting rollers 10 are provided on both sides of the electrode E, there is a high possibility that foreign matter such as electrode powder and foil powder generated at the cutting portion of the electrode E will occur on both sides of the electrode E. Alternatively, even in an embodiment in which the slitting rollers 10 are provided on one side of the electrode E, foreign matter such as fine electrode powder and foil powder may flow to the side opposite to the knife 11. At this time, according to an embodiment in which the upper support 21 and the lower support 22 are provided at the same time, foreign matter adhering to both sides of the electrode E can be removed smoothly.

[0069] Figure 7 It is shown Figure 6 A side view of the bracket 20 is shown.

[0070] In another aspect of the present disclosure, the micropores H of the lower bracket 22 disposed at a position of the upper bracket 21 facing the micropores H may be the same type of micropores H as the micropores H disposed in the upper bracket 21 .

[0071] For example, refer to Figure 7, the micropores H of the upper bracket 21 include blowing holes BH and suction holes SH, and the micropores H of the lower bracket 22 also include blowing holes BH and suction holes SH. At this time, the micropores H arranged on the leftmost side of the upper bracket 21 in the figure can be the blowing holes BH, and the micropores H of the lower bracket 22 arranged at the position corresponding to the blowing holes BH can also be the blowing holes BH. In addition, the micropores H at the second position on the left side of the upper bracket 21 in the figure can be the suction holes SH, and the micropores H of the lower bracket 22 located at the position corresponding to the suction holes SH can also be the suction holes SH. That is to say, in the above embodiment, no matter how the arrangement order of the micropores H in the bracket 20 of the upper bracket 21 or the lower bracket 22 is, the same type of micropores H can be set at the corresponding positions of the upper bracket 21 and the lower bracket 22.

[0072] According to this structure, the upward and downward forces applied to the electrode E at a specific point of the electrode E can offset each other, thereby preventing the electrode E from bending or shaking. For example, if the suction hole SH is set at a specific position in the upper bracket 21 and the blowing hole BH is set at a corresponding position in the lower bracket 22, then unlike the present disclosure, the electrode E in between may receive a force pulled upward by the suction hole SH of the upper bracket 21, and may receive a force pushed upward by the blowing hole BH of the lower bracket 22. Therefore, the electrode E is more likely to bend upward at a specific point. If the micropore H of the upper bracket 21 adjacent to the specific position is the blowing hole BH and the micropore H of the lower bracket 22 set at the corresponding position is the suction hole SH, then the inserted electrode E at this time receives a downward force through the blowing hole BH of the upper bracket 21 and receives a downward pulling force through the suction hole SH of the lower bracket 22. Therefore, the electrode E is more likely to bend downward at this point. Finally, the electrode E is pressurized upward and downward, thereby increasing the possibility of electrode vibration and bending.

[0073] On the other hand, according to the present disclosure, the micropores H of the lower support 22 provided at the position facing the micropores H of the upper support 21 are the same type of micropores H as the micropores H provided in the upper support 21, and the forces applied to the electrode E at a specific point on the electrode E can offset each other. For example, referring to Figure 7, the micropore H arranged at the leftmost side of the upper support 21 may be a blowing hole BH, and the micropore H of the lower support 22 arranged at the corresponding position may also be a blowing hole BH. In this case, the electrode between the upper support 21 and the lower support 22 is pressed downward by the upper support 21, and is pressed upward by the lower support 22. Therefore, the upward and downward pressures applied to the electrode E offset each other, so that the electrode E may not deviate upward or downward. In other words, electrode vibration and electrode bending can be prevented. Similarly, the micropore H arranged at the second position from the left side of the upper support 21 may be a suction hole SH, and the micropore H of the lower support 22 arranged at the corresponding position may also be a suction hole SH. In this case, the electrode E between the upper support 21 and the lower support 22 is pressed upward by the upper support 21, and is pressed downward by the lower support 22. Therefore, the upward and downward pressures applied to the electrode E offset each other, so that the electrode E may not deviate upward or downward. In other words, electrode vibration and electrode bending can be prevented.

[0074] In another aspect of the present disclosure, the blowing holes BH and the suction holes SH may be alternately arranged.

[0075] For example, refer to Figure 6 In one bracket 20, the blowing holes BH and the suction holes SH may be arranged alternately. Preferably, the blowing holes BH and the suction holes SH may be arranged in a checkerboard pattern. In other words, the microholes H located on the top, bottom, left and right sides of the suction hole SH may be the blowing holes BH. Similarly, the microholes H located on the top, bottom, left and right sides of the blowing hole BH may be the suction holes SH.

[0076] According to this structure, the micropores H of the same type are not gathered in any specific area, so it is possible to prevent a strong pressure from being applied to a specific area. For example, if the blowing holes BH are concentrated in a specific area, the pressure pushing the electrode E can be increased in the area. As a result, the possibility of electrode vibration or electrode bending increases. At the same time, according to the present disclosure, since the suction holes SH and the blowing holes BH are arranged alternately, it is possible to prevent a large pressure from occurring in any specific area. That is, if the suction holes SH and the blowing holes BH are arranged alternately, a structure such as Figure 5 The minute airflow shown in FIG. 1 is reduced, and therefore, a thin air layer can be formed in a direction parallel to the electrode E. Therefore, it is possible to prevent pressure from being applied to the electrode E in a direction perpendicular to the electrode E at a specific point.

[0077] Figure 8 is a diagram for explaining a bracket 20 according to another embodiment of the present disclosure. Fig. 9 It is a diagram for explaining a bracket 20 according to still another embodiment of the present disclosure. Fig.10 It is used to illustrate that Fig. 9 FIG. 1 is a diagram of an electrode manufacturing apparatus 1 of a holder 20 .

[0078] As another embodiment of the present disclosure, refer to Figure 8 and Fig. 9 , the blowing holes BH may be arranged in a straight line, and the suction holes SH may be arranged in a straight line. Here, the arrangement line of the blowing holes BH and the arrangement line of the suction holes SH may be arranged alternately.

[0079] As one embodiment of the present disclosure, refer to Figure 8 , the arrangement line of the blowing holes BH and the arrangement line of the suction holes SH can be perpendicular to the moving direction of the electrode E.

[0080] According to this structure, the arrangement line of the suction holes SH is perpendicular to the moving direction of the electrode, so the foreign matter suction effect can be improved. More specifically, since all points in the width direction of the electrode E passing through the bracket 20 pass through the arrangement line of the suction holes SH at the same time, foreign matter located on the electrode E can be effectively removed.

[0081] As another embodiment, refer to Fig. 9 and Fig.10 , the arrangement line of the blowing holes BH and the arrangement line of the suction holes SH may be parallel to the moving direction of the electrode E. Preferably, the arrangement line of the suction holes SH may be arranged at a position corresponding to the electrode line cut by the knife 11 provided on the slitting roller 10. Fig.10 , the arrangement line of the suction holes SH may be set on the line cut by the knife 11 .

[0082] According to this structure, since the arrangement line of the suction holes SH is set at the position corresponding to the electrode line cut by the knife 11, the suction efficiency can be improved, especially at the cutting point of the electrode E. That is, there is a high possibility that foreign matter such as electrode powder and foil powder is concentrated at the point cut by the knife 11, and according to the present disclosure, the foreign matter accumulation area can be concentratedly sucked.

[0083] Fig.11 It is a diagram for explaining an electrode manufacturing apparatus 1 according to still another embodiment of the present disclosure.

[0084] In another aspect of the present disclosure, the electrode manufacturing apparatus 1 may include a plurality of supports 20 .

[0085] A plurality of brackets 20 may be provided along the moving direction of the electrode E. For example, referring to Fig.11 , the first support 20 may be disposed downstream in the moving direction of the electrode E to be spaced apart from the slitting roller 10 by a predetermined distance. In addition, the second support 20 may be disposed downstream in the moving direction of the electrode E to be spaced apart from the first support 20 by a predetermined distance.

[0086] In another aspect of the present disclosure, the first bracket 20 and the second bracket 20 may have different arrangements of the micropores H. For example, Fig.11As shown, the arrangement of the microholes H of the first bracket 20 can be configured so that the arrangement line of the blowing holes BH and the arrangement line of the suction holes SH are perpendicular to the moving direction of the electrode E, as shown in FIG. Figure 8 In addition, the arrangement of the microholes H of the second bracket 20 can be configured so that the arrangement line of the blowing holes BH and the arrangement line of the suction holes SH are parallel to the moving direction of the electrode E, as shown in FIG. Fig. 9 shown.

[0087] According to this structure, foreign matter that cannot be removed by one bracket 20 can be removed by multiple brackets 20. In other words, the efficiency of removing foreign matter can be further improved. Fig.11 In the embodiment shown, since all points in the width direction of the electrode E simultaneously pass through the arrangement line of the suction holes SH due to the first bracket 20, foreign matter located on the electrode E can be effectively removed, and the second bracket 20 can be used to concentrate the suction of the foreign matter accumulation area.

[0088] Meanwhile, on the contrary, the first bracket 20 may have Fig. 9 The micropores H are arranged as shown, and the second bracket 20 may have Figure 8 The arrangement of the micropores H is shown. Alternatively, in another embodiment, the arrangement of the micropores H of the first bracket 20 and the arrangement of the micropores H of the second bracket 20 can be set to be the same.

[0089] In another aspect of the present disclosure, the bracket 20 may be installed and fixed by the frame 30 .

[0090] Reference again Figure 1 , the bracket 20 may be mounted on, for example, a frame 30 located at one side of the bracket 20 . Figure 1 Only an example in which the frame 30 is located below the bracket 20 is shown, but an embodiment in which the frame 30 is located on the side of the bracket 20 is also possible. Figure 1 Only the frame 30 with the lower bracket 22 installed is shown, and of course, the frame 30 with the upper bracket 21 installed may also be included in the electrode manufacturing apparatus 1 of the present disclosure.

[0091] In yet another aspect of the present disclosure, the electrode manufacturing apparatus 1 may include a filtering device connected to the air intake 40 and capable of filtering and separating foreign matter.

[0092] Although not shown in the figure, the filter device can filter foreign matter such as electrode powder and foil powder. For example, the filter device can be installed on a pipeline connected to the micropore H. Alternatively, the filter device can be set upstream of the air intake 40. The filter device can be set in multiples. The filter device can separate and discharge foreign matter such as foil powder and electrode powder.

[0093] According to this structure, it is possible to prevent foreign matter from penetrating into other devices included in the electrode manufacturing apparatus 1. In particular, according to this structure, it is possible to prevent foreign matter from penetrating into the air intake 40. Moreover, according to the structure in which a plurality of filtering devices are provided, the filtering efficiency can be further improved.

[0094] According to the various embodiments described above, foreign matter adhering to the electrode E can be effectively removed. Moreover, because a tiny airflow is formed between the electrode E and the bracket 20, the electrode can be prevented from fluttering. In other words, since a tiny air layer is formed in the area adjacent to the electrode E, the electrode E can be prevented from sagging or bending. As a result, wrinkles that may appear on the electrode E can be flattened. Moreover, since the bracket 20 is configured to cover the electrode E, according to the present disclosure, foreign matter deposited on the surface of the electrode E can be smoothly removed.

[0095] Meanwhile, in this specification, terms indicating directions such as up and down are used, but these terms are used only for the convenience of description, and it is obvious to those skilled in the art that these terms may change depending on the position of the target or observer.

[0096] The present disclosure has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the present disclosure, are given by way of illustration only, as various changes and modifications within the scope of the present disclosure will be apparent to those skilled in the art from these detailed descriptions.
