Technical Field

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of Korean Patent Application No. 10-2023-0063049, filed on May 16, 2023, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference in its entirety.

[0003] The present invention relates to an electrode manufacturing apparatus and an electrode manufacturing method, and more particularly, to an electrode manufacturing apparatus and an electrode manufacturing method that improve a defect rate caused by non-cutting of an electrode and prevent a reduction in productivity caused by breakage of an electrode. Background Art

[0004] With the technological development and increasing demand for mobile devices, the demand for secondary batteries as energy sources has rapidly increased. In particular, secondary batteries have attracted considerable attention as energy sources for power-driven devices (such as electric bicycles, electric vehicles, and hybrid electric vehicles) and for mobile devices (such as mobile phones, digital cameras, laptop computers, and wearable devices).

[0005] Based on the shape of the battery case, the secondary battery can be divided into a cylindrical battery having an electrode assembly installed in a cylindrical metal container, a square battery having an electrode assembly installed in a square metal container, or a pouch-type battery having an electrode assembly installed in a pouch-shaped case made of an aluminum laminate. Here, the electrode assembly installed in the battery case serves as a power generation element capable of charging / discharging, and includes a stacked structure of a cathode, an anode, and a separator interposed between the cathode and the anode. The electrode assembly can be divided into a roll type formed by inserting a separator between a long sheet cathode and a long sheet anode and winding them, and a stacked type formed by stacking a plurality of cathodes and anodes in sequence and inserting a separator between the cathode and the anode.

[0006] Among them, in particular, the use of pouch-shaped batteries configured to have a structure in which such a stacked or stacked / folded electrode assembly is installed in a pouch-shaped battery case made of an aluminum laminate sheet has gradually increased due to low manufacturing cost, light weight, easy shape modification, etc.

[0007] In particular, the electrodes included in the secondary battery are manufactured by coating an electrode active material onto an electrode current collector, and a portion of the manufactured electrode is grooved to process (cut) an electrode tab so that the electrode tab is manufactured into a desired shape. Conventional electrode manufacturing equipment includes a jig portion having a predetermined pattern or shape and a laser cutting portion, thereby facilitating the processing of the electrode tab based on the pattern or shape of the jig portion.

[0008] However, due to the processing (cutting) process or the external environment, conventional electrode manufacturing devices may cause foreign matter to accumulate inside the pattern or shape of the fixture portion. Foreign matter accumulated inside the pattern or shape of the fixture portion may hinder laser cutting, which leads to the problem that the electrode joint is not processed into the desired pattern or shape. The non-cut portion of the electrode joint may cause defects such as breakage of the electrode joint or folding of the joint, which leads to problems such as process loss and increase in non-operating time and reduced productivity.

[0009] Therefore, there is a need to develop an electrode manufacturing apparatus and an electrode manufacturing method that can improve a defect rate caused by non-cutting of electrodes and prevent a reduction in productivity caused by breakage of electrodes. Summary of the Invention

[0011] An object of the present disclosure is to provide an electrode manufacturing apparatus and an electrode manufacturing method which improve a defect rate caused by non-cutting of an electrode and prevent a reduction in productivity caused by breakage of an electrode.

[0012] The technical objectives of the present disclosure are not limited to the above-mentioned objectives, and other objectives not mentioned herein may be clearly understood by those skilled in the art based on the following detailed description and accompanying drawings.

[0013] Technical Solution

[0014] According to one embodiment of the present disclosure, an electrode manufacturing device is provided, which includes: a laser cutting part, which cuts at least a portion of an electrode; a clamp part, which forms a predetermined pattern on at least a portion of the electrode during the cutting process of the laser cutting part; a foreign matter removal part, which removes foreign matter from the clamp part; and an inspection part, which inspects whether there is foreign matter in the clamp part, wherein when the inspection part does not confirm that there is foreign matter in the clamp part, the clamp part moves to a position corresponding to the laser cutting part, and when the inspection part confirms that there is foreign matter in the clamp part, the clamp part moves to a position corresponding to the foreign matter removal part.

[0015] When the foreign matter of the clamp portion is removed from the foreign matter remover, the clamp portion is moved again to a position corresponding to the inspection portion, and the inspection portion can confirm whether the foreign matter of the clamp portion has been removed.

[0016] When the inspection unit does not reconfirm that the clamp unit has foreign matter, the clamp unit is moved to a position corresponding to the laser cutting unit, and when the inspection unit reconfirms that the clamp unit has foreign matter, the clamp unit can be removed.

[0017] When the area without foreign matter formed based on the total area of the pattern formed on the clamp portion is greater than 90% and less than 100%, the inspection unit determines that no foreign matter is confirmed in the clamp portion, and when the area without foreign matter formed based on the total area of the pattern formed on the clamp portion is greater than 0% and less than 90%, the inspection unit determines that the presence of foreign matter is confirmed.

[0018] The inspection part is a visual camera, and the inspection part can confirm the foreign matter in the clamp part based on an image acquired by the visual camera.

[0019] The clamp portion may be rotated and moved to positions corresponding to the laser cutting portion, the foreign matter removal portion, and the inspection portion.

[0020] The electrode manufacturing device further includes a main body, and the clamp portion is located inside the main body, wherein the clamp portion can rotate as the main body rotates.

[0021] The laser cutting portion, the foreign matter removing portion, and the inspecting portion may be respectively located on an outer peripheral surface of the body.

[0022] The body may have a drum structure formed in a cylindrical shape.

[0023] The inspection portion and the foreign matter removal portion are positioned to be spaced apart from each other in directions opposite to each other, and the laser cutting portion may be located between the inspection portion and the foreign matter removal portion.

[0024] The clamp portion includes a clamp body and a clamp pattern portion located at a center of the clamp body, and the inspection portion may confirm whether a foreign substance exists in the clamp pattern portion.

[0025] According to another embodiment of the present disclosure, an electrode manufacturing method for manufacturing an electrode using the above-mentioned electrode manufacturing is provided, the method comprising the following steps: a fixture part foreign matter confirmation step, wherein the fixture part foreign matter confirmation step moves the fixture part to a position corresponding to an inspection part, and confirms whether there is foreign matter in the fixture part through the inspection part; a fixture part moving step, wherein the fixture part moving step moves the fixture part to a position corresponding to the laser cutting part or the foreign matter removal part according to whether there is foreign matter in the fixture part; and a foreign matter removal step, wherein the foreign matter removal step removes foreign matter from the fixture part through the foreign matter removal part when the fixture part moves to the position corresponding to the foreign matter removal part, wherein, in the fixture part moving step, when no foreign matter is confirmed to be present in the fixture part, the fixture part moves to the position corresponding to the laser cutting part, and when foreign matter is confirmed to be present in the fixture part, the fixture part moves to the position corresponding to the foreign matter removal part.

[0026] In the foreign matter removal step, after the foreign matter removal part removes the foreign matter from the clamp part, the method may further include the following steps: a clamp part re-moving step, in which the clamp part re-moves the clamp part to a position corresponding to the inspection part again; and a clamp part foreign matter re-confirming step, in which the clamp part foreign matter re-confirming step reconfirms whether there is a foreign matter in the clamp part through the inspection part.

[0027] When the presence of foreign matter in the jig portion is not reconfirmed by the inspection portion, the method may further include moving the jig portion to a position corresponding to the laser cutting portion.

[0028] When it is reconfirmed from the inspection part that there is foreign matter in the clamp part, the method further includes the step of disassembling the clamp part, wherein the disassembled clamp part can be replaced by another clamp part, or the user can directly remove the foreign matter in the clamp part.

[0029] Beneficial effects

[0030] According to an embodiment, the electrode manufacturing device and electrode manufacturing method disclosed herein can remove foreign matter from the clamping part through a foreign matter removal part, and then reconfirm whether the foreign matter has been removed through an inspection part, thereby improving the non-cutting of the electrode and the resulting defect rate and preventing the reduction in productivity caused by electrode breakage.

In the drawings, the thickness of some layers and regions are exaggerated for the sake of convenience of description.

[0039] In addition, throughout the specification, when a part is referred to as “including” or “comprising” a certain component, it means that the part may further include other components, but does not exclude other components, unless otherwise stated.

[0040] Furthermore, throughout the specification, when referred to as a “plane”, this means when the target portion is viewed from the upper side, and when it is referred to as a “cross section”, this means when the target portion is viewed from the side of a vertically cut cross section.

[0041] Now, an electrode manufacturing apparatus according to one embodiment of the present disclosure will be described.

[0042] Figure 1 is a diagram illustrating an electrode manufacturing apparatus according to one embodiment of the present disclosure. Figure 2 It shows Figure 1 An enlarged view of a portion of the electrode manufacturing apparatus. Figure 3 It shows Figure 2 Figure 2 is a cross-sectional view of a fixture portion.

[0043] Reference Figure 1 and Figure 2 According to one embodiment of the present disclosure, an electrode manufacturing device 1000 includes a laser cutting part 100 for cutting at least a portion of an electrode; a fixture part 300 for forming a predetermined pattern on at least a portion of the electrode during the cutting process of the laser cutting part 100; a foreign matter removal part 400 for removing foreign matter from the fixture part 300; and an inspection part 500 for inspecting whether there is foreign matter in the fixture part 300.

[0044] Although not specifically shown in the figure, the wound electrode is conveyed while being unwound, and the laser cutting unit 100 can irradiate the conveyed electrode with a laser to cut at least a portion of the electrode. As an example, the electrode has an electrode current collector coated with an electrode active material, and the laser cutting unit 100 can cut the electrode joint portion where no electrode active material is applied to the electrode current collector. Here, the laser cutting unit 100 can adjust the amount and speed of laser irradiation based on conditions such as the thickness of the electrode current collector or the coating thickness of the electrode active material.

[0045] Although not specifically shown in the drawings, the jig part 300 supports the transferred electrode, and at the same time, the laser cutting part 100 facing the electrode may provide a shape or pattern for cutting the electrode. Figure 3 The clamp portion 300 includes a clamp body 310 and a clamp pattern portion 350 located at the center of the clamp body 310. Here, the shape or pattern of the clamp pattern portion 350 is not limited to Figure 3 The shapes or patterns shown are shown, and various shapes or patterns can be applied according to the cutting conditions of the electrode.

[0046] Therefore, in the electrode manufacturing apparatus 1000 according to the present embodiment, the laser irradiated from the laser cutting part 100 passes through the jig pattern part 350 of the jig part 300 and may cut the electrode according to the shape or pattern of the jig pattern part 350 .

[0047] The foreign matter remover 400 can automatically remove foreign matter from the clamp portion 300. For example, the foreign matter remover 400 can include a brush member and / or a suction member. Here, the brush member can brush off foreign matter attached to the outer surface of the clamp portion 300. In other words, the brush member can brush the outer surface of the clamp portion 300. Furthermore, the suction member can remove foreign matter attached to the outer surface of the clamp portion 300 and / or foreign matter separated from the clamp portion 300 by the brush member.

[0048] Therefore, in the electrode manufacturing apparatus 1000 according to the present embodiment, foreign matter can be automatically removed from the clamp portion 300 by the foreign matter removal portion 400, thereby preventing non-cutting and joint folding defects of the electrode caused by foreign matter attached to the clamp portion 300. In addition, the electrode manufacturing apparatus 1000 according to the present embodiment does not require the user to separately separate the clamp portion 300 to remove foreign matter, and can further improve productivity and production speed.

[0049] The inspection unit 500 can confirm whether foreign matter is located inside the clamp portion 300. More specifically, the inspection unit 500 can confirm whether foreign matter is located inside the clamp pattern portion 350. As an example, the inspection unit 500 can be a visual camera, and the inspection unit 500 can confirm foreign matter in the clamp portion 300 based on the image captured by the visual camera. More specifically, in the image captured by the visual camera, the inspection unit 500 compares the number of pixels in the clamp portion 300 containing foreign matter with the number of pixels constituting the clamp pattern portion 350, and can confirm whether foreign matter is present in the clamp portion 300 and the extent of the foreign matter in the clamp portion 300. As another example, the inspection unit 500 can include a deep learning model pre-learned based on the image captured by the visual camera. Here, the deep learning model can be pre-learned to compare the number of pixels in the clamp portion 300 containing foreign matter based on the number of pixels constituting the clamp pattern portion 350, based on the image captured by the visual camera. However, the device is not limited to this, and any device capable of confirming foreign matter in the clamp portion 300 can be included in this embodiment.

[0050] More specifically, when the area of the pattern formed on the fixture pattern section 350 that is free of foreign matter is greater than 90% and less than 100% based on the total area of the pattern formed on the fixture pattern section 350, the inspection section 500 can determine that no foreign matter is confirmed in the fixture section 300. Furthermore, when the area of the pattern formed on the fixture pattern section 350 that is free of foreign matter is greater than 0% and less than 90% based on the total area of the pattern formed on the fixture pattern section 350, the inspection section 500 can determine that a foreign matter is confirmed. Here, the area may refer to the sum of the areas of the pixels included in the image captured by the visual camera. However, the numerical range for confirming the presence of foreign matter by the inspection section 500 is not limited to this and may vary depending on the specific configuration of the inspection section 500.

[0051] Therefore, in the electrode manufacturing apparatus 1000 according to this embodiment, the inspection unit 500 confirms whether there is foreign matter in the fixture unit 300 based on the above numerical range, and even if some foreign matter appears within the normal operating range of the electrode manufacturing apparatus 1000, it can operate without equipment failure.

[0052] In contrast, in the electrode manufacturing device 1000 according to the present embodiment, when the inspection unit 500 confirms whether there is foreign matter in the fixture unit 300 based on a numerical range outside the above-mentioned numerical range, even if some foreign matter appears within the normal operating range of the electrode manufacturing device 1000, there is a problem that equipment failure may occur and productivity and production speed may be reduced.

[0053] Reference Figure 3 , Figure 3(a) shows a case where the area where the foreign matter 390 is not formed is 100% based on the total area of the pattern formed on the jig pattern portion 350, and Figure 3 (b) shows a case where the area where the foreign matter 390 is not formed is 92%, and Figure 3 (c) shows a case where the area where the foreign matter 390 is not formed is 75%.

[0054] As an example, Figure 3 (a) and Figure 3 The jig pattern portion 350 of (b) is a case where the area where the foreign matter 390 is not formed is 90% or more and 100% or less based on the total area of the pattern formed on the jig pattern portion 350, and therefore, the inspection unit 500 can determine that Figure 3 (a) and Figure 3 No foreign matter 390 was found in the fixture pattern portion 350 of (b). Figure 3 The jig pattern portion 350 of (c) is a case where the area where the foreign matter 390 is not formed is 0% or more and less than 90% based on the total area of the pattern formed in the jig pattern portion 350, and therefore, the inspection unit 500 can determine that Figure 3 In (c), foreign matter 390 is confirmed in the jig pattern portion 350 .

[0055] Reference Figure 1 and Figure 2 , the fixture part 300 can rotate and move to positions corresponding to the laser cutting part 100, the foreign matter removal part 400 and the inspection part 500. More specifically, the present device further includes a main body 200, and the fixture part 300 is located inside the main body 200, wherein the fixture part 300 can rotate as the main body 200 rotates. More specifically, the corresponding positions can mean that the corresponding components are positioned in a state of facing each other. Here, the laser cutting part 100, the foreign matter removal part 400 and the inspection part 500 can be respectively located on the outer circumferential surface of the main body 200.

[0056] As an example, the main body 200 may have a drum structure formed in a cylindrical shape. However, the structure is not limited thereto, and any structure in which the clamp portion 300 can be moved to positions corresponding to the laser cutting portion 100, the foreign matter removal portion 400, and the inspection portion 500 may be included in the present embodiment.

[0057] like Figure 2 As shown, the inspection part 500 and the foreign matter removal part 400 are positioned to be spaced apart from each other in directions opposite to each other, and the laser cutting part 100 may be located between the inspection part 500 and the foreign matter removal part 400. More specifically, the clamp part 300 may be rotated and moved to positions a, b, c, and d of the main body 200, as shown in FIG. Figure 2 As shown. Here, positions a, b, c and d may have an angle of 90 degrees with each other. Here, the laser cutting part 100 may be arranged at a position corresponding to position (a) of the main body 200, the foreign matter removal part 400 may be arranged at a position corresponding to position (b) of the main body 200, and the inspection part 500 may be arranged at a position corresponding to position (d) of the main body 200. Here, the clamp part 300 may be on standby at position (c) of the main body 200. However, the positions of the laser cutting part 100, the foreign matter removal part 400 and the inspection part 500 are not limited thereto, and the positions of the laser cutting part 100, the foreign matter removal part 400 and the inspection part 500 may be appropriately changed.

[0058] Therefore, in the electrode manufacturing device 1000 according to this embodiment, since the clamp part 300 can be moved to positions corresponding to the laser cutting part 100, the foreign matter removal part 400 and the inspection part 500, there is an advantage that it is easy to confirm whether there are foreign matters in the clamp part 300 through the foreign matter removal part 400, and it is easy to move to the laser cutting part 100 or the inspection part 500 according to whether there are foreign matters.

[0059] Figure 4 It is an explanation Figure 2 Flowchart of the operating sequence of the electrode manufacturing apparatus.

[0060] Reference Figure 2 and Figure 4 Before the electrode is cut by the laser cutting unit 100, the jig unit 300 may be moved to a position (d) corresponding to the inspection unit 500. Here, when no foreign matter is confirmed in the jig unit 300 by the inspection unit 500, the jig unit 300 is moved to a position (a) corresponding to the laser cutting unit 100, and when the foreign matter is confirmed in the jig unit 300 by the inspection unit 500, the jig unit 300 may be moved to a position (b) corresponding to the foreign matter removal unit 400.

[0061] However, despite Figure 2 It is illustrated that the clamp part 300 rotates in the clockwise direction, but the rotation direction of the clamp part 300 is not limited thereto, and a case where the clamp part 300 rotates in the counterclockwise direction may be included in the present embodiment.

[0062] Furthermore, when the foreign matter of the clamp part 300 is removed by the foreign matter remover 400 , the clamp part 300 moves again to the position (d) corresponding to the inspection part 500 , and the inspection part 500 can reconfirm whether the foreign matter exists in the clamp part 300 .

[0063] In addition, when the inspection unit 500 does not reconfirm that the clamp unit 300 has foreign matter, the clamp unit 300 moves to the position (a) corresponding to the laser cutting unit 100, and when the inspection unit 500 reconfirms that the clamp unit 300 has foreign matter, the clamp unit 300 can be disassembled.

[0064] Specifically, when the inspection unit 500 reconfirms that the fixture unit 300 has foreign matter, the fixture unit 300 can be moved to the standby position (c). The fixture unit 300 located at the standby position (c) can be disassembled. The disassembled fixture unit 300 can be used by the user to confirm the state of the fixture unit 300. If the fixture unit 300 is contaminated, the user can directly remove the contamination, and if the fixture unit 300 is damaged, it can be replaced with another fixture unit.

[0065] Therefore, in the electrode manufacturing apparatus 1000 according to the present embodiment, after the foreign matter in the jig part 300 is removed by the foreign matter removal part 400, the inspection part 500 can reconfirm the presence or absence of foreign matter, which makes it possible to quantitatively manage the degree of foreign matter in the jig part 300. In addition, it is possible to prevent the degree of foreign matter in the jig part 300 from deepening beyond a certain level, thereby improving the non-cutting of the electrode and the resulting defect rate, and preventing a decrease in productivity caused by electrode breakage.

[0066] Next, a method of manufacturing an electrode according to another embodiment of the present disclosure will be described.

[0067] Reference Figure 2 and Figure 4 According to another embodiment of the present disclosure, an electrode manufacturing method is an electrode manufacturing method for manufacturing an electrode using the electrode manufacturing apparatus 1000, the method comprising the following steps: a fixture portion foreign body confirmation step (S100, S200), wherein the fixture portion foreign body confirmation step (S100, S200) moves the fixture portion to a position (d) corresponding to the inspection portion 500, and confirms whether there is foreign matter in the fixture portion 300 by the inspection portion 500; a fixture portion moving step (S 300, S400), the clamp part moving step (S300, S400) moves the clamp part 300 to a position (b) corresponding to the laser cutting part 100 or the foreign matter removal part 400 according to whether there is foreign matter in the clamp part 300; and a foreign matter removal step (S400), the foreign matter removal step (S400) removes foreign matter from the clamp part 300 through the foreign matter removal part 400 when the clamp part 300 moves to the position (b) corresponding to the foreign matter removal part 400.

[0068] In the clamp part moving step (S300, S400), when no foreign matter is confirmed in the clamp part 300, the clamp part moves to a position (a) corresponding to the laser cutting part 100, and when foreign matter is confirmed in the clamp part 300, the clamp part moves to a position (b) corresponding to the foreign matter removal part 400.

[0069] In the foreign matter removal step (S400), after the foreign matter removal part 400 removes the foreign matter from the clamp part 300, the method may further include the following steps: a clamp part re-moving step (S500), which moves the clamp part 300 to a position (d) corresponding to the inspection part 500 again; and a clamp part foreign matter re-confirming step (S600), which reconfirms whether there is foreign matter in the clamp part 300 through the inspection part 500.

[0070] In the jig part foreign matter reconfirmation step (S600), when the inspection part 500 does not reconfirm that there is foreign matter in the jig part 300, the method further includes a step (S300) of moving the jig part 300 to a position (a) corresponding to the laser cutting part 100.

[0071] In the clamp part foreign matter reconfirmation step (S600), when the inspection unit 500 reconfirms that the clamp part 300 has foreign matter, the method further includes a step (S700) of disassembling the clamp part 300. Here, when the clamp part 300 is disassembled, an NG determination is made, and the disassembled clamp part 300 can be replaced with another clamp part as described above, or the user can directly remove the foreign matter from the clamp part 300.

[0072] Therefore, in the electrode manufacturing method according to the present embodiment, after the foreign matter is removed from the jig part 300 by the foreign matter removal part 400, the inspection part 500 can reconfirm the presence or absence of foreign matter, thereby quantitatively managing the degree of foreign matter in the jig part 300. In addition, the degree of foreign matter in the jig part 300 can be prevented from deepening beyond a certain level, thereby improving the non-cutting of the electrode and the resulting defect rate, and preventing a decrease in productivity caused by electrode breakage.

[0073] Although the present invention has been described in detail above with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that the scope of the present disclosure is not limited thereto and that various modifications and improvements may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
