Description

Technical Field

[0001] [Cross-reference to Related Applications] This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0063049, filed on May 16, 2023, and all the contents disclosed in the literature of the Korean patent application are included as part of this specification.

[0002] The present invention relates to an electrode manufacturing apparatus and an electrode manufacturing method, and more specifically, to an electrode manufacturing apparatus and an electrode manufacturing method that improve the defect rate due to uncut electrodes and prevent productivity degradation due to electrode breakage.

Background Art

[0003] With the development of mobile device technology and the increasing demand, the demand for secondary batteries as an energy source has been rapidly increasing. In particular, secondary batteries are attracting attention not only as an energy source for mobile devices such as mobile phones, digital cameras, notebook computers, and wearable devices, but also as an energy source for power devices such as electric bicycles, electric vehicles, and hybrid electric vehicles.

[0004] Such secondary batteries are classified into cylindrical batteries and prismatic batteries in which an electrode assembly is built into a cylindrical or prismatic metal can depending on the shape of the battery case, and pouch-type batteries in which an electrode assembly is built into a pouch-type case of an aluminum laminate sheet. Here, the electrode assembly built into the battery case is composed of a positive electrode, a negative electrode, and a separator structure interposed between the positive electrode and the negative electrode, and is a power generation element capable of charge and discharge. It is classified into a jelly roll type in which a separator is interposed between long sheet-shaped positive and negative electrodes coated with an active material and wound up, and a stack type in which a large number of positive and negative electrodes are sequentially laminated with a separator interposed therebetween.

[0005] Among these, in particular, the usage amount of pouch-type batteries having a structure in which a stack-type or stack / foldable-type electrode assembly is built into a pouch-type battery case made of an aluminum laminate sheet is gradually increasing due to reasons such as low manufacturing cost, small weight, and easy deformability.

[0006] In particular, electrodes included in secondary batteries are manufactured by coating an electrode active material onto an electrode current collector, and a portion of the manufactured electrode is notched to process (cut) an electrode tab, thereby manufacturing the electrode tab into a desired shape. Conventional electrode manufacturing equipment includes a jig section having a predetermined pattern or shape and a laser cutting section, and the processing of the electrode tab is facilitated based on the pattern or shape of the jig section.

[0007] However, with conventional electrode manufacturing equipment, foreign matter could accumulate inside the pattern or shape of the jig due to the processing (cutting) process and external environment. This foreign matter accumulated inside the jig pattern or shape can interfere with laser cutting, resulting in the electrode tabs not being processed into the desired pattern or shape. Such uncut portions of the electrode tabs can cause defects such as fracture or breakage of the electrode tabs, leading to process losses and downtime, and reducing productivity.

[0008] Therefore, it is necessary to develop electrode manufacturing equipment and methods that improve the defect rate due to uncut electrodes and prevent a decrease in productivity due to electrode breakage. [Overview of the project] [Problems that the invention aims to solve]

[0009] The problem that this invention aims to solve is to provide an electrode manufacturing apparatus and an electrode manufacturing method that improve the defect rate due to uncut electrodes and prevent a decrease in productivity due to electrode breakage.

[Means for solving the problem]

[0011] An electrode manufacturing apparatus according to one embodiment of the present invention includes a laser cutting section for cutting at least a portion of an electrode; a jig section for forming a predetermined pattern on at least a portion of the electrode during cutting by the laser cutting section; a foreign matter removal section for removing foreign matter from the jig section; and an inspection section for inspecting the presence or absence of foreign matter in the jig section. The jig section moves to a position corresponding to the laser cutting section if no foreign matter is detected in the jig section by the inspection section, and moves to a position corresponding to the foreign matter removal section if foreign matter is detected in the jig section by the inspection section.

[0012] When the foreign matter in the jig is removed by the foreign matter removal unit, the jig is moved back to a position corresponding to the inspection unit, and the inspection unit can confirm whether or not the foreign matter in the jig has been removed.

[0013] If the inspection unit does not reconfirm that there is any foreign matter in the jig, the jig portion moves to a position corresponding to the laser cutting portion, and if the inspection unit reconfirms that there is any foreign matter in the jig portion, the jig portion can be detached.

[0014] The inspection unit can determine that no foreign matter has been found on the jig if the area on the jig where no foreign matter was formed is between 90% and 100% of the total area of ​​the pattern formed on the jig, and can determine that foreign matter has been found if the area on the jig where no foreign matter was formed is between 0% and less than 90% of the total area of ​​the pattern formed on the jig.

[0015] The inspection unit is a vision camera, and the inspection unit can identify foreign objects in the jig based on the image acquired by the vision camera.

[0016] The jig portion can be rotated to a position corresponding to the laser cutting portion, the foreign matter removal portion, and the inspection portion.

[0017] The jig portion further includes a main body portion located inside it, and the jig portion can rotate as the main body portion rotates.

[0018] The laser cutting section, the foreign matter removal section, and the inspection section can be positioned on the outer circumferential surface of the main body, respectively.

[0020] The inspection unit and the foreign matter removal unit are positioned facing each other and spaced apart from each other, and the laser cutting unit can be positioned between the inspection unit and the foreign matter removal unit.

[0021] The jig portion includes a jig body and a jig pattern portion located in the center of the jig body, and the inspection portion can check for the presence or absence of foreign matter in the jig pattern portion.

[0022] An electrode manufacturing method for manufacturing electrodes using the electrode manufacturing apparatus described above, comprising: a jig portion foreign matter confirmation step in which the jig portion moves to a position corresponding to the inspection portion and the inspection portion confirms the presence or absence of foreign matter in the jig portion; a jig portion moving step in which the jig portion moves to a position corresponding to the laser cutting portion or the foreign matter removal portion depending on the presence or absence of foreign matter in the jig portion; and a foreign matter removal step in which, if the jig portion moves to a position corresponding to the foreign matter removal portion, the foreign matter removal portion removes the foreign matter in the jig portion, wherein if no foreign matter is confirmed in the jig portion moving step, the jig portion moves to a position corresponding to the laser cutting portion, and if foreign matter is confirmed in the jig portion, the jig portion moves to a position corresponding to the foreign matter removal portion.

[0023] The foreign matter removal step may further include a jig portion repositioning step in which, after the foreign matter removal unit has removed the foreign matter from the jig portion, the jig portion is repositioned to a position corresponding to the inspection unit; and a jig portion foreign matter reconfirmation step in which the inspection unit confirms whether or not the foreign matter has been removed from the jig portion.

[0024] When the foreign matter in the jig part is not reconfirmed by the inspection part, the step of moving the jig part to the position corresponding to the laser cutting part can be further included.

[0025] When the foreign matter in the jig part is reconfirmed by the inspection part, the step of removing the jig part is further included, and the removed jig part can be exchanged with another jig part or the user can directly remove the foreign matter in the jig part.

[Figure 4] It is a flowchart for explaining the operation sequence of the electrode manufacturing apparatus of FIG. 2.

Modes for Carrying Out the Invention

[0029] Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings, so that they can be easily implemented by a person with ordinary skill in the art to which the present invention pertains. The present invention can be implemented in several different forms and is not limited to the embodiments described herein.

[0030] To clearly explain the present invention, irrelevant parts have been omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.

[0031] Furthermore, the dimensions and thicknesses of each component shown in the drawings are arbitrarily indicated for the sake of explanation, and therefore the present invention is not necessarily limited to those shown. In the drawings, the thicknesses are shown enlarged to clearly represent multiple layers and regions. Also, in the drawings, the thicknesses of some layers and regions are shown exaggerated for the sake of explanation.

[0032] Furthermore, throughout this specification, when a part "includes" a certain component, unless otherwise stated, it means that it may include other components rather than excluding them.

[0033] Furthermore, throughout the specification, "on a plane" means when the subject is viewed from above, and "on a cross-section" means when the cross-section obtained by cutting the subject perpendicularly is viewed from the side.

[0034] The following describes an electrode manufacturing apparatus according to one embodiment of the present invention.

[0035] Figure 1 is a drawing showing an electrode manufacturing apparatus according to one embodiment of the present invention. Figure 2 is a drawing showing a magnified portion of the electrode manufacturing apparatus in Figure 1. Figure 3 is a drawing showing a cross-section of the jig portion in Figure 2.

[0036] Referring to Figures 1 and 2, an electrode manufacturing apparatus 1000 according to one embodiment of the present invention includes: a laser cutting unit 100 for cutting at least a portion of an electrode; a jig unit 300 for forming a predetermined pattern on at least a portion of the electrode when the laser cutting unit 100 is cutting; a foreign matter removal unit 400 for removing foreign matter from the jig unit 300; and an inspection unit 500 for inspecting the jig unit 300 for the presence or absence of foreign matter.

[0037] Although not shown in detail in the drawings, the wound electrode is transported simultaneously with its unwinding, and the laser cutting unit 100 can irradiate the transported electrode with a laser to cut at least a portion of the electrode. For example, the electrode has an electrode active material coated on an electrode current collector, and the laser cutting unit 100 can cut the electrode tab portion on the electrode current collector where the electrode active material is not coated. Here, the laser cutting unit 100 can adjust the laser irradiation amount and speed based on conditions such as the thickness of the electrode current collector or the coating thickness of the electrode active material.

[0038] Although not shown in detail in the drawings, the jig section 300 can support the transported electrode and simultaneously provide a shape or pattern for the laser cutting section 100 facing the electrode to cut the electrode. Referring to Figure 3, the jig section 300 includes a jig body section 310 and a jig pattern section 350 located in the center of the jig body section 310. Here, the shape or pattern of the jig pattern section 350 is not limited to Figure 3, and various shapes or patterns can be applied depending on the cutting conditions of the electrode.

[0039] As a result, in the electrode manufacturing apparatus 1000 according to this embodiment, the laser irradiated from the laser cutting section 100 passes through the jig pattern section 350 of the jig section 300, and the electrode can be cut along the shape or pattern of the jig pattern section 350.

[0040] The foreign matter removal unit 400 can automatically remove foreign matter from the jig unit 300. For example, the foreign matter removal unit 400 may include a brush member and / or a suction member. Here, the brush member can brush off foreign matter adhering to the outer surface of the jig unit 300. In other words, the brush member can brush the outer surface of the jig unit 300. The suction member can remove foreign matter adhering to the outer surface of the jig unit 300 and / or foreign matter that falls from the jig unit 300 by the brush member.

[0041] As a result, in the electrode manufacturing apparatus 1000 according to this embodiment, the jig section 300 can automatically remove foreign matter via the foreign matter removal section 400, preventing uncut electrodes and broken tabs caused by foreign matter adhering to the jig section 300. At the same time, the electrode manufacturing apparatus 1000 according to this embodiment does not require the user to separately separate the jig section 300 to remove foreign matter, thereby further improving productivity and production speed.

[0042] The inspection unit 500 can confirm the presence or absence of foreign matter located inside the jig unit 300. More specifically, the inspection unit 500 can confirm the presence or absence of foreign matter located inside the jig pattern unit 350. For example, the inspection unit 500 may be a vision camera, and the inspection unit 500 can confirm foreign matter in the jig unit 300 based on the image acquired by the vision camera. More specifically, using the image acquired by the vision camera, the inspection unit 500 can confirm the presence or absence of foreign matter in the jig unit 300 and the degree of foreign matter by comparing the number of pixels containing foreign matter in the jig unit 300 with the number of pixels constituting the jig pattern unit 350. As another example, the inspection unit 500 may include a pre-trained deep learning model based on the image acquired by the vision camera. Here, the deep learning model can be pre-trained to compare the number of pixels in the jig section 300 containing foreign matter with the number of pixels constituting the jig pattern section 350, based on the image acquired by the vision camera. However, it is not limited to this, and any device capable of detecting foreign matter in the jig section 300 can be included in this embodiment.

[0043] More specifically, the inspection unit 500 can determine that no foreign matter has been found in the jig unit 300 if the area where no foreign matter is formed is between 90% and 100% of the total area of ​​the pattern formed in the jig pattern unit 350, and can determine that foreign matter has been found if the area where no foreign matter is formed is between 0% and less than 90% of the total area of ​​the pattern formed in the jig pattern unit 350. Here, the area can mean the total area of ​​pixels included in the image acquired by the vision camera. However, the numerical range for whether or not foreign matter has been found by the inspection unit 500 is not limited to this range and may be changed by the detailed settings of the inspection unit 500.

[0044] As a result, in the electrode manufacturing apparatus 1000 according to this embodiment, the inspection unit 500 checks for the presence or absence of foreign matter in the jig unit 300 based on the above-mentioned numerical range, and even if some foreign matter occurs within the normal operating range of the electrode manufacturing apparatus 1000, it can continue to operate without the equipment becoming inoperable.

[0045] In contrast, in the electrode manufacturing apparatus 1000 according to this embodiment, if the inspection unit 500 checks for the presence or absence of foreign matter in the jig unit 300 based on a numerical range exceeding the above-mentioned numerical range, even if some foreign matter occurs within the normal operating range of the electrode manufacturing apparatus 1000, equipment failure occurs, leading to a problem of reduced productivity and production speed.

[0046] Referring to Figure 3, Figure 3(a) shows the case where the area where foreign matter 390 is not formed is 100% based on the total area of ​​the pattern formed on the jig pattern section 350, Figure 3(b) shows the case where the area where foreign matter 390 is not formed is 92%, and Figure 3(c) shows the case where the area where foreign matter 390 is not formed is 75%.

[0047] For example, in the jig pattern sections 350 of Figure 3(a) and Figure 3(b), the area where foreign matter 390 is not formed is between 90% and 100% of the total area of ​​the pattern formed on the jig pattern section 350. Therefore, the inspection unit 500 can determine that no foreign matter 390 is found in the jig pattern sections 350 of Figure 3(a) and Figure 3(b). In contrast, in the jig pattern section 350 of Figure 3(c), the area where foreign matter 390 is not formed is between 0% and less than 90% of the total area of ​​the pattern formed on the jig pattern section 350. Therefore, the inspection unit 500 can determine that foreign matter 390 is found in the jig pattern section 350 of Figure 3(c).

[0048] Referring to Figures 1 and 2, the jig section 300 can rotate to positions corresponding to the laser cutting section 100, the foreign matter removal section 400, and the inspection section 500. More specifically, the jig section 300 further includes a main body section 200 located inside, and the jig section 300 can rotate as the main body section 200 rotates. More specifically, corresponding positions can mean that the components are positioned facing each other. Here, the laser cutting section 100, the foreign matter removal section 400, and the inspection section 500 can be positioned on the outer circumferential surface of the main body section 200, respectively.

[0049] For example, the main body 200 may have a drum structure formed in a cylindrical shape. However, it is not limited to this, and any structure in which the jig 300 can move to a position corresponding to the laser cutting unit 100, the foreign matter removal unit 400, and the inspection unit 500 can be included in this embodiment.

[0050] As shown in Figure 2, the inspection unit 500 and the foreign matter removal unit 400 are positioned apart from each other in a direction facing each other, and the laser cutting unit 100 can be positioned between the inspection unit 500 and the foreign matter removal unit 400. More specifically, the jig unit 300 can be rotated to positions a, b, c, and d of the main body unit 200, as shown in Figure 2. Here, positions a, b, c, and d can have angles of 90 degrees to each other. Here, the laser cutting unit 100 can be positioned at the position a of the main body unit 200, the foreign matter removal unit 400 can be positioned at the position b of the main body unit 200, and the inspection unit 500 can be positioned at the position d of the main body unit 200. Here, the jig unit 300 can be stationary at position c of the main body unit 200. However, the positions of the laser cutting unit 100, the foreign matter removal unit 400, and the inspection unit 500 are not limited to these positions, and their positions can be appropriately changed.

[0051] As a result, in the electrode manufacturing apparatus 1000 according to this embodiment, the jig section 300 can be moved to a position corresponding to the laser cutting section 100, the foreign matter removal section 400, and the inspection section 500, and the foreign matter removal section 400 can easily check for the presence or absence of foreign matter in the jig section 300, and the check for the presence or absence of foreign matter makes it easy to move to the laser cutting section 100 or the inspection section 500.

[0052] Figure 4 is a flowchart illustrating the operating sequence of the electrode manufacturing apparatus shown in Figure 2.

[0053] Referring to Figures 2 and 4, the jig section 300 can be moved to a position (d) corresponding to the inspection section 500 before the electrodes are cut by the laser cutting section 100. Here, if no foreign matter is detected on the jig section 300 by the inspection section 500, the jig section 300 can be moved to a position (a) corresponding to the laser cutting section 100, and if foreign matter is detected on the jig section 300 by the inspection section 500, it can be moved to a position (b) corresponding to the foreign matter removal section 400.

[0054] However, although Figure 2 shows the jig portion 300 rotating in a clockwise direction, the direction of rotation of the jig portion 300 is not limited to this, and counterclockwise rotation can also be included in this embodiment.

[0055] Furthermore, if the foreign matter in the jig section 300 is removed by the foreign matter removal section 400, the jig section 300 moves back to a position (d) corresponding to the inspection section 500, and the inspection section 500 can reconfirm whether or not the foreign matter has been removed from the jig section 300.

[0056] Furthermore, if the inspection unit 500 does not reconfirm that the jig unit 300 is containing foreign matter, the jig unit 300 moves to a position (a) corresponding to the laser cutting unit 100, and if the inspection unit 500 reconfirms that the jig unit 300 is containing foreign matter, the jig unit 300 can be detached.

[0057] In particular, if foreign matter is reconfirmed in the jig section 300 by the inspection section 500, the jig section 300 can be moved to the standby position (c). The jig section 300 located in the standby position (c) can be detached. The removed jig section 300 can be checked by the user, and if the jig section 300 is contaminated, the user can remove the contaminants directly, and if the jig section 300 is damaged, it can be replaced with another jig section.

[0058] As a result, in the electrode manufacturing apparatus 1000 according to this embodiment, the inspection unit 500 can reconfirm the presence or absence of foreign matter in the jig unit 300 after the foreign matter has been removed by the foreign matter removal unit 400, and the degree of foreign matter in the jig unit 300 can be quantitatively controlled. Furthermore, it is possible to prevent the degree of foreign matter in the jig unit 300 from deepening beyond a certain level, improve the rate of uncut electrodes and the resulting defect rate, and prevent a decrease in productivity due to electrode breakage.

[0059] The following describes an electrode manufacturing method according to another embodiment of the present invention.

[0060] Referring to Figures 2 and 4, another embodiment of the present invention is an electrode manufacturing method for manufacturing electrodes in the electrode manufacturing apparatus 1000 described above, comprising: a jig part foreign matter confirmation step (S100, S200) in which the jig part 300 moves to a position (d) corresponding to the inspection unit 500 and the inspection unit 500 confirms the presence or absence of foreign matter in the jig part 300; a jig part moving step (S300, S400) in which the jig part 300 moves to a position (b) corresponding to the laser cutting unit 100 or the foreign matter removal unit 400 depending on the presence or absence of foreign matter in the jig part 300; and a foreign matter removal step (S400) in which, if the jig part 300 moves to a position (b) corresponding to the foreign matter removal unit 400, the foreign matter removal unit 400 removes the foreign matter from the jig part 300.

[0061] In the jig movement step (S300, S400), if no foreign matter is found in the jig 300, it moves to position (a) corresponding to the laser cutting unit 100 (S300). If foreign matter is found in the jig 300, it moves to position (b) corresponding to the foreign matter removal unit 400 (S400).

[0062] In the foreign matter removal step (S400), after the foreign matter removal unit 400 removes the foreign matter from the jig unit 300, the jig unit 300 is moved again in a jig unit repositioning step (S500) to a position (d) corresponding to the inspection unit 500; and the inspection unit 500 may further include a jig unit foreign matter reconfirmation step (S600) to confirm whether or not the foreign matter has been removed from the jig unit 300.

[0063] If, in the jig section foreign matter reconfirmation step (S600), no foreign matter is reconfirmed in the jig section 300 from the inspection section 500, the step (S300) may further include moving to a position (a) corresponding to the laser cutting section 100.

[0064] The procedure further includes a step (S700) in which, if foreign matter is reconfirmed in the jig section 300 by the inspection section 500 during the jig section foreign matter reconfirmation step (S600), the jig section 300 is removed. If the jig section 300 is removed, an NG (Not Good) judgment is made, and the removed jig section 300 is either replaced with another jig section as described above, or the user can directly remove the foreign matter from the jig section 300.

[0065] As a result, in the electrode manufacturing method according to this embodiment, after the jig section 300 has been cleaned of foreign matter by the foreign matter removal section 400, the inspection section 500 can reconfirm the presence or absence of foreign matter, and the degree of foreign matter in the jig section 300 can be quantitatively controlled. Furthermore, it is possible to prevent the degree of foreign matter in the jig section 300 from deepening beyond a certain level, improve the rate of uncut electrodes and the resulting defect rate, and prevent a decrease in productivity due to electrode breakage.

[0066] Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto. Various modifications and improvements by those skilled in the art, utilizing the basic concepts of the present invention as defined in the following claims, also fall within the scope of the present invention.
