Description

Technical Field

[0001] This disclosure relates to apparatus and methods for forming electrode plate tab patterns. Background Technology

[0002] While primary batteries are not designed to be (re)charged, secondary batteries (also known as rechargeable batteries) are designed to be discharged and recharged. Low-capacity secondary batteries are widely used in portable small electronic devices such as smartphones, feature phones, laptops, digital cameras, and portable camcorders, while high-capacity secondary batteries are widely used as power sources for motors in hybrid and electric vehicles, and for storing electricity (e.g., household and / or utility-scale power storage). A secondary battery typically includes an electrode assembly containing positive and negative electrodes, a housing that houses the two electrodes, and electrode terminals connected to the electrode assembly.

[0003] Typically, the electrodes of a secondary battery are formed through the following processes: mixing of raw materials for the mixed electrode, coating of the mixed slurry onto the substrate of the electrode plate, drying of the mixed slurry, rolling to reduce the thickness of the coated electrode, dicing of the electrode, and cutting of the electrode to form connecting pieces.

[0004] Before the cutting process, a terminal pattern can be formed on the electrode plate at the location where the electrode terminal will be formed, and then the electrode terminal can be formed at the location of the terminal pattern. Traditionally, a single laser array is used to form the terminal pattern along the conveying equipment that carries the electrode plate.

The terms or words used in this specification and claims should not be construed as having a general or dictionary meaning, but should be interpreted in a meaning and concept consistent with the technical spirit of the present disclosure, based on the principle that the inventor is capable of properly defining the concepts of the terms to best describe his / her invention as his / her own lexicographer.

[0044] The embodiments described in this specification and the configurations shown in the accompanying drawings are only some of the embodiments of this disclosure and do not represent all the technical spirit, aspects, and features of this disclosure. Accordingly, it should be understood that various equivalents and modifications are possible at the time of filing this application, which can replace or modify the embodiments described herein.

[0045] It will be understood that when an element or layer is referred to as being "on" another element or layer, "connected to," or "attached to" another element or layer, the element or layer may be directly on, connected to, or attached to the other element or layer, or one or more intermediary elements or layers may be present. When an element or layer is referred to as being "directly on" another element or layer, "directly connected to," or "directly attached to" another element or layer, no intermediary element or layer is present. For example, when a first element is described as being "attached" or "connected" to a second element, the first element may be directly attached to or connected to the second element, or the first element may be indirectly attached to or connected to the second element via one or more intermediary elements.

[0046] The embodiments described herein can be illustrated with reference to the cross-sectional and / or plan views that serve as exemplary views of this disclosure. In the drawings, the thickness of films and regions may be enlarged for effective description of the technical content. Therefore, the regions presented as examples in the drawings have general properties, and the shapes of the illustrated regions may be used to illustrate specific shapes of device regions. Therefore, this should not be construed as limiting the scope of this disclosure. Although terms such as first, second, and third are used to describe various components in the various embodiments herein, these components should not be limited to these terms. These terms are used only to distinguish one component from another. The embodiments described and illustrated herein include supplementary embodiments thereof. Throughout the specification, the same reference numerals refer to the same elements.

[0047] As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items. Furthermore, when describing embodiments of this disclosure, the use of “may” means “one or more embodiments of this disclosure.” Expressions such as “at least one of” and “any one of”, when placed after a list of elements, modify the entire list of elements without modifying individual elements in that list. When phrases such as “at least one of A, B, and C,” “at least one of A, B, or C,” “at least one selected from the group of A, B, and C,” or “at least one selected from A, B, and C” are used to specify a list of elements A, B, and C, the phrase may refer to any and all suitable combinations or subsets of A, B, C, A and B, A and C, B and C, or A and B and C, A, B, and C. As used herein, the term “use” and variations thereof may be considered synonymous with the term “utilize” and variations thereof, respectively. As used herein, the terms “substantially,” “approximately,” and similar terms are used as approximate terms rather than terms of degree and are intended to describe inherent biases in measured or calculated values ​​that will be recognized by one of ordinary skill in the art.

[0048] It will be understood that although the terms "first," "second," "third," etc., can be used to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or portion discussed below may be referred to as the second element, component, region, layer, or portion.

[0049] In this document, spatial relative terms such as “below,” “under,” “down,” “above,” and “above” are used to describe the relationship between one element or feature as shown in the figures and another (or several) other elements or features. It will be understood that, in addition to the orientation shown in the figures, spatial relative terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “below” or “under” other elements or features will be oriented “above” or “directly above” other elements or features. Therefore, the term “below” can include both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly.

[0050] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to limit this disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “an” are intended to include the plural forms as well. It will be further understood that, when used in this specification, the term “comprising” designates the presence of stated features, integrals, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof.

For example, the range “1.0 to 10.0” is intended to include, for example, 2.4 to 7.6, all subranges between the stated minimum value of 1.0 and the stated maximum value of 10.0 (inclusive), i.e., all subranges with a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0. Any maximum numerical limit described herein is intended to include all smaller numerical limits, and any minimum numerical limit described in this specification is intended to include all larger numerical limits. Therefore, the applicant reserves the right to amend this specification (including the claims) to explicitly detail any subranges included within the scope expressly described herein.

[0052] Referring to two compared elements, features, etc., as "identical" can mean that they are "substantially identical." Therefore, the phrase "substantially identical" can include cases with deviations considered low in the art (e.g., deviations below 5%). Additionally, when a parameter is stated to be consistent in a given region, this can mean that it is consistent in terms of average value.

[0053] Throughout this specification, unless otherwise stated, each element may be singular or plural.

[0054] Placing any element "above (or below)" or "above (below)" another element can mean that the arbitrary element can contact the upper (or lower) surface of the element, and that another element can also be located between the element and the arbitrary element disposed on (or below) the element.

[0055] Additionally, it will be understood that when a component is referred to as “connected,” “linked,” or “attached” to another component, these components can be directly “connected,” “linked,” or “attached” to each other, or another component can be “between” these components.

[0057] The terminology used in this specification is for describing embodiments of this disclosure and is not intended to limit this disclosure.

[0058] Figure 1 An apparatus 10 for forming electrode plate contact patterns according to an embodiment of the present disclosure is shown.

[0059] The apparatus 10 for forming electrode plate tab patterns may include a conveying section 100, a first pattern forming section 200, and a second pattern forming section 300.

[0060] The apparatus 10 for forming electrode plate tab patterns (hereinafter referred to as electrode plate tab pattern forming apparatus 10) may include N pattern forming sections spaced apart at predetermined intervals. However, for better understanding and ease of description, Figure 1 An embodiment of the electrode plate bonding strip pattern forming apparatus 10 is shown, which may include two pattern forming portions (i.e., a first pattern forming portion 200 and a second pattern forming portion 300).

[0061] According to one embodiment, the electrode plate 20 on which the terminal block pattern is formed can correspond to either a positive electrode or a negative electrode. In the case of a positive electrode, the electrode plate 20 can be formed by applying an active material, such as a transition metal oxide, to a current collector plate formed on a metal foil such as aluminum or an aluminum alloy. In the case of a negative electrode, the electrode plate 20 can be formed by applying an active material, such as graphite or carbon, to a current collector plate formed on a metal foil such as copper, a copper alloy, nickel, or a nickel alloy.

[0062] In one embodiment, the electrode plate 20 may initially exist in a wound state after being coated with an active material. The electrode plate 20 may be conveyed by the conveying section 100 in a first direction (e.g., the X direction) and may be unwound. The electrode plate 20 may be conveyed in the first direction and may form a plurality of first terminal pattern 211 and a plurality of second terminal pattern 311. The first terminal pattern 211 and the second terminal pattern 311 may be formed on the electrode plate 20, and the electrode plate 20 may be wound at the end of the conveying section 100.

[0063] According to one embodiment, the conveying section 100 can convey an electrode plate 20 coated with an active material in a first direction (X-axis direction). In one embodiment, the conveying section 100 may include a plurality of conveying rollers connected to respective drive motors to convey the electrode plate 20 in the first direction. In one embodiment, the conveying section 100 may include a conveyor belt connected to the drive motors to convey the electrode plate 20 in the first direction, but this disclosure is not limited thereto.

[0064] According to one embodiment, the drive motor that powers the conveyor roller of the conveying section 100 and the drive motor that powers the buffer roller may be a separate configuration or a single configuration with different gear ratios, but this disclosure is not limited thereto.

[0065] According to one embodiment, the rotational speed of the conveyor roller of the conveying section 100 can be inversely proportional to the period during which the first pattern forming section 200 forms the first terminal pattern 211 on the electrode plate 20 and the period during which the second pattern forming section 300 forms the second terminal pattern 311 on the electrode plate 20. In one embodiment, as the rotational speed of the conveyor roller of the conveying section 100 increases, the conveying speed of the electrode plate 20 in the first direction can increase. Correspondingly, the period during which the first pattern forming section 200 forms the first terminal pattern 211 on the electrode plate 20 can be reduced, and the period during which the second pattern forming section 300 forms the second terminal pattern 311 on the electrode plate 20 can also be reduced.

[0066] According to one embodiment, the first pattern forming portion 200 may form a first terminal pattern 211 on the electrode plate 20. The first terminal pattern 211 may include a pattern of any shape having an indication of the position of the electrode terminal to be formed on the electrode plate 20.

[0067] According to one embodiment, the first pattern forming portion 200 may include a plurality of first laser portions 210. According to one embodiment, the first laser portions 210 may be arranged along multiple rows and columns at predetermined intervals. First tab patterns 211 may be formed on the electrode plate 20 in rows and columns corresponding to the rows and columns in which the first laser portions 210 are arranged.

[0068] According to one embodiment, the first laser portion 210 can irradiate a laser beam onto the electrode plate 20 to form a first bonding pattern 211 on the electrode plate 20. In one embodiment, a portion of the active material coated on the electrode plate 20 can be peeled off, and multiple first bonding patterns 211 can be formed, but this disclosure is not limited thereto. In one embodiment, welding can be performed on the boundary region corresponding to the first bonding pattern 211 by irradiating the electrode plate 20 with a laser beam from the first laser portion 210.

[0069] According to one embodiment, the second pattern forming portion 300 can be configured to be spaced apart from the first pattern forming portion 200 in a first direction. The second pattern forming portion 300 can form a second terminal pattern 311 on the electrode plate 20. The second terminal pattern 311 can be formed on the electrode plate 20 and can be spaced apart from the first terminal pattern 211 by a predetermined first distance. The first terminal pattern 211 and the second terminal pattern 311 can be formed to have the same (e.g., substantially the same) pattern. However, if the arrangement (e.g., rows and columns) of the first laser portion 210 and the second laser portion 310 is different, the first terminal pattern 211 and the second terminal pattern 311 can be formed to have different patterns.

[0070] According to one embodiment, the second pattern forming portion 300 may include a plurality of second laser portions 310. According to one embodiment, the second laser portions 310 may be arranged at regular intervals along multiple rows and columns. Second terminal block patterns 311 may be formed on the electrode plate 20 in rows and columns corresponding to the rows and columns in which the second laser portions 310 are arranged.

[0071] According to one embodiment, the second laser portion 310 can irradiate a laser beam onto the electrode plate 20 to form a second contact pattern 311 on the electrode plate 20. In one embodiment, a portion of the active material coated on the electrode plate 20 can be peeled off and multiple second contact patterns 311 can be formed, but this disclosure is not limited thereto.

[0072] In one embodiment, a plurality of first terminal block patterns 211 and a plurality of second terminal block patterns 311 are formed by dividing the electrode plate 20 into 10 regions. In one embodiment, the first pattern forming portion 200 may form the first terminal block patterns 211 in the first region, the third region, the fifth region, the seventh region, and the ninth region. The second pattern forming portion 300 may form the second terminal block patterns 311 in the second region, the fourth region, the sixth region, the eighth region, and the tenth region.

[0073] In one embodiment, the first pattern forming portion 200 may be disposed on the path traversed by the transfer electrode plate 20 to form a first contact pattern 211 on the electrode plate 20. In one embodiment, a first region of the electrode plate 20 is disposed below the first pattern forming portion 200, and the first pattern forming portion 200 forms the first contact pattern 211 by irradiating the first region of the electrode plate 20 with a laser beam. In one embodiment, when the first region moves in a first direction and a second region of the electrode plate 20 is below the first pattern forming portion 200, the first pattern forming portion 200 does not irradiate the electrode plate 20 with a laser beam. In one embodiment, when the second region moves in a first direction and a third region of the electrode plate 20 is below the first pattern forming portion 200, the first pattern forming portion 200 can form the first contact pattern 211 by irradiating the electrode plate 20 with a laser beam.

[0074] In one embodiment, the second pattern forming portion 300 may be configured to be spaced apart from the first pattern forming portion 200 along the path traversed by the transfer electrode plate 20. The second pattern forming portion 300 may be located at the rear end of the first pattern forming portion 200 along the path traversed by the transfer electrode plate 20. The second pattern forming portion 300 may form the second contact pattern 311 after the first contact pattern 211 is formed on the electrode plate 20, and may form the second contact pattern 311 adjacent to the first contact pattern 211. In one embodiment, when the first region of the electrode plate 20 is below the second pattern forming portion 300, the second pattern forming portion 300 will not irradiate the electrode plate 20 with a laser beam. The first contact pattern 211 may be formed in the first region of the electrode plate 20 as it passes under the first pattern forming portion 200. In one embodiment, when the first region of the electrode plate moves in a first direction and the second region of the electrode plate 20 is below the second pattern forming portion 300, the second pattern forming portion 300 can form a second contact pattern 311 by irradiating the second region of the electrode plate 20 with a laser beam. In one embodiment, when the second region of the electrode plate 20 moves in the first direction and the third region of the electrode plate 20 is below the second pattern forming portion 300, the second pattern forming portion 300 will not irradiate the electrode plate 20 with a laser beam. The first contact pattern 211 can be formed in the third region of the electrode plate 20 while passing under the first pattern forming portion 200. By repeating this operation in sequence, the first contact pattern 211 and the second contact pattern 311 can be formed on the electrode plate 20. The first contact pattern 211 formed in the first region and the second contact pattern 311 formed in the second region can be formed to be spaced apart by a predetermined first distance. The second contact pattern 311 formed in the second region and the first contact pattern 211 formed in the third region can be formed to be spaced apart by a predetermined first distance. In other words, multiple adjacent first terminal block patterns 211 and multiple adjacent second terminal block patterns 311 can be formed to be spaced apart from each other by a predetermined first distance.

[0075] In one embodiment, the first pattern forming portion 200 and the second pattern forming portion 300 may simultaneously form a first terminal pattern 211 and a second terminal pattern 311 on the electrode plate 20 disposed below them.

[0076] In one embodiment, the electrode plate tab pattern forming apparatus 10 can simultaneously form multiple adjacent first tab patterns 211 and multiple adjacent second tab patterns 311 at predetermined intervals, thereby improving process efficiency by forming tab patterns 211 and 311 on the electrode plate 20 at predetermined intervals.

[0077] Figure 2An apparatus 10 for forming electrode plate contact patterns according to an embodiment of the present disclosure is shown. Figure 3 The configuration of the electrode plate moving portion 400 according to an embodiment of the present disclosure is shown. Figure 4 The configuration of an electrode plate movement controller 450 according to an embodiment of the present disclosure is shown.

[0078] refer to Figures 2 to 4 The electrode plate connecting piece pattern forming device 10 may further include an electrode plate moving part 400.

[0079] According to one embodiment, the conveying section 100 may include a buffer roller 110. The buffer roller 110 can move the electrode plate 20. In one embodiment, the buffer roller 110 can rotate clockwise (e.g., in a fifth direction) to move the electrode plate 20 in a first direction (e.g., the X direction). In one embodiment, the buffer roller 110 can rotate counterclockwise (e.g., in a sixth direction) to move the electrode plate 20 in a second direction opposite to the first direction. As used herein, clockwise (e.g., in the fifth direction) and counterclockwise (e.g., in the sixth direction) directions are for reference only. Figure 2 The description of the electrode plate connection pattern forming device 10 shown in the figure is convenient, and if the conveying direction of the electrode plate 20 is the second direction, the rotation direction of the buffer roller 110 can be changed.

[0080] According to one embodiment, the second pattern forming portion 300 can output a signal for specifying the position of forming the second contact pattern 311, so as to display the second contact pattern line on the electrode plate 20 (see [link]). Figure 5 (312). In one embodiment, the second pattern forming portion 300 can output a laser beam that can be detected by a position sensor 430 included in the electrode plate moving portion 400 without damaging the electrode plate 20, so as to display the second terminal pattern line 312 on the electrode plate 20.

[0081] According to one embodiment, the electrode plate moving portion 400 can move the electrode plate 20, such that the second terminal pattern 311 is formed to be spaced apart from the first terminal pattern 211 by a predetermined first distance. For example... Figure 1As described, a plurality of adjacent first terminal block patterns 211 and a plurality of adjacent second terminal block patterns 311 should be formed to be precisely spaced apart from each other by a predetermined first distance. However, due to external factors (e.g., interference), adjacent first terminal block patterns 211 and adjacent second terminal block patterns 311 may have different spacings. Before forming the second terminal block pattern 311, the electrode plate moving portion 400 can measure the position where the first terminal block pattern 211 is to be formed and the position where the second terminal block pattern 311 is to be formed, and then move the electrode plate 20 such that the second terminal block pattern 311 is formed to be spaced apart from the first terminal block pattern 211 by a predetermined first distance.

[0145] In step S1323, a second distance between a point of the first connector pattern and a point of the second connector pattern line can be measured based on the measured position of the first connector pattern and the position of the second connector pattern line (e.g., by using the distance error calculation section 350).

[0146] In step S1324, the error between the preset first distance and the measured second distance can be calculated (for example, by using the distance error calculation section 350).

[0147] Steps S1321 to S1324 and reference Figure 12 The steps S1311 to S1314 described are essentially the same.

[0148] In step 1325, error control based on the preset first distance and the measured second distance may include moving the second laser portion 310 in the second pattern forming portion 300 in a first direction or a second direction opposite to the first direction (e.g., by using a second laser portion movement controller 360). According to one embodiment, as... Figure 6 As shown, when the measured second distance L2 is shorter than the preset first distance L1, the second pattern forming portion 300 can control the second laser portion 310 to move in the second direction.
