[0002] The present invention relates to a stack cell taping device and a stack cell taping method using the same, and more particularly, to a stack cell taping device for wrapping and fixing around a stacked battery cell and a stack cell taping method using the same.

Background Art

[0003] As the technology development and demand for mobile devices increase, rechargeable secondary batteries are used as an energy source for various mobile devices. Secondary batteries are also attracting attention as an energy source for electric vehicles, hybrid electric vehicles, etc., which are presented as alternatives to existing gasoline vehicles, diesel vehicles, etc. that use fossil fuels.

[0004] <00000?15]] Secondary batteries are classified into cylindrical batteries and prismatic batteries in which the electrode assembly is built into a cylindrical or rectangular metal can according to the shape of the battery case, and pouch-type batteries in which the electrode assembly is built into a pouch-type case of an aluminum laminate sheet.

[0005] The electrode process for manufacturing the positive electrode and negative electrode of a secondary battery includes a mixing process of mixing raw materials, a coating process of applying the mixed slurry to a foil and drying it, a rolling process of passing the electrode between two rolls and pressing it while spreading the slurry flat, a slitting process of cutting the electrode in the width direction according to the designed battery specifications by a slitter, and a notching process of leaving a portion for grounding a tab on the uncoated plain portion and cutting off the other portions.

[0006] Subsequently, the secondary battery undergoes a stacking process, which involves stacking the positive electrode, negative electrode, and separator membrane of the battery after the notching process has been completed.

[0007] Figure 1 illustrates the process of taping stack cells using a conventional stack cell taping device, and Figure 2 illustrates the state of the taped stack cells.

[0008] Referring to Figures 1 and 2, in order to fix the stacked cells 10 that are piled up in a continuous stacking process, the stacked cells 10 are taped with adhesive member 20.

[0009] However, if the thickness of the stacked cell 10 is greater than the thickness of the guide 31, the roller portion 33 for pressing the adhesive member 20 will move while pressing against the edges of the stacked cell 10, which is likely to cause bending of the separation membrane or damage (tearing) of the stacked cells, resulting in a defect in the stacked cell 10.

[0036] Hereinafter, embodiments that allow a person with ordinary skill in the art to easily implement the present invention will be described in detail based on the attached drawings. However, in describing the operating principles of preferred embodiments of the present invention in detail, if it is determined that a specific description of a related known function or configuration may unnecessarily obscure the gist of the present invention, such detailed description will be omitted.

[0037] Furthermore, the same reference numerals shall be used throughout the drawings for parts that have similar functions and operations. Throughout the specification, when it is said that one part is connected to another part, this includes not only direct connections but also indirect connections through other elements in between. Also, when it is said that a component is included, unless otherwise stated, it does not mean that other components are excluded, but rather that other components may be included.

[0038] The stack cell taping apparatus according to the present invention will be described below.

[0039] Figure 3 is a side view illustrating the sensor of a stack cell taping device according to one embodiment of the present invention, and Figure 4 is a diagram showing a state in which a pair of rollers are positioned on the side of a stack cell in a stack cell taping device according to one embodiment of the present invention. Figure 5 is a diagram showing a state in which a pair of rollers are positioned parallel to the upper and lower surfaces of a stack cell in a stack cell taping device according to one embodiment of the present invention, and Figure 6 is a diagram showing a state in which a pair of rollers move along the upper and lower surfaces of a stack cell while pressing the adhesive member in a stack cell taping device according to one embodiment of the present invention, and Figure 7 is a diagram illustrating the connecting member of a stack cell taping device according to one embodiment of the present invention.

[0040] Specifically, Figure 4 is a diagram illustrating the compressed state of the position adjustment guide of a stack cell taping device according to one embodiment of the present invention, and Figure 5 is a diagram illustrating the state in which the height of the guide portion is adjusted by the position adjustment guide shown in Figure 4.

[0041] Referring together to Figures 2 to 7, the stack cell taping device according to the present invention includes a support base 100, a sensor 200, and a taping section 300.

[0042] Multiple support bases 100 can be provided, arranged at predetermined intervals to support the stack cells 10. The stack cells 10 can be transported by an operator or via a separate supply device.

[0043] For example, the predetermined interval may be an interval that can stably support the stack cell 10 and corresponds to the width of the taping portion 300 or the width of the adhesive member 20.

[0044] For example, the support base 100 can be made of a member with a flat top and bottom surface so as to support the stack cell 10.

[0045] Multiple sensors 200 can be provided to measure the thickness t of the stack cell 10, and can be positioned above and below the stack cell 10 to measure the thickness t of the stack cell 10.

[0046] For example, the sensor 200 may be positioned at intervals between multiple support bases 100.

[0047] For example, multiple sensors 200 located on the upper and lower sides of the stack cell 10 are positioned on the same vertical line, and by measuring the distance between the upper surface of the stack cell 10 and the sensors, and the distance between the lower surface of the stack cell 10 and the sensors, the thickness t of the stack cell 10 can be measured.

[0048] Here, the sensor 200 may be, but is not limited to, a laser sensor or a vision camera, and may be composed of a sensor that is obvious to those skilled in the art.

[0049] Furthermore, for example, the sensor 200 can transmit the measured thickness t of the stack cell 10 to a control unit (not shown).

[0050] A control unit (not shown) performs overall control to ensure that each component can perform its intended function properly. Such a control unit may be embodied in hardware form, in software form, or in a combination of hardware and software. The control unit can be embodied in a variety of forms that are obvious to those skilled in the art.

[0051] On the other hand, the taping section 300 may include a gripping section 310, a roller section 320, a guide section 330, and a drive member 340. For example, the taping section 300 can be configured to tape the sides of a stack cell 10 supported by a plurality of support bases 100.

[0052] First, the gripping portion 310 can be configured to grip both ends of the adhesive member 20 so as to tape the stack cell 10 on its side surface. For example, the adhesive member 20 may be a tape.

[0053] The gripping portion 310 may include a first gripping unit 311 that grips one end of the adhesive member 20 and a second gripping unit 312 that grips the other end of the adhesive member 20.

[0054] For example, one end of the adhesive member 20 and the first gripping unit 311 may be located on the upper side (12 o'clock direction with respect to Figure 4), and the other end of the adhesive member 20 and the second gripping unit 312 may be located on the lower side (6 o'clock direction with respect to Figure 4).

[0055] Therefore, the first gripping unit 311 is positioned above the stack cell 10, and the adhesive member 20 can be used to tape one upper surface of the stack cell 10.

[0056] Furthermore, the second gripping unit 312 is located below the stack cell 10, and the adhesive member 20 can be used to tape one side of the lower surface of the stack cell 10.

[0057] Here, the first gripping unit 311 and the second gripping unit 312 may be vacuum suction plates. Since such vacuum suction plates are obvious to those skilled in the art, their specific operating principles will be omitted.

[0058] The roller section 320 may include a first roller 321 and a second roller 322.

[0059] The first roller 321 can be configured to move one end of the adhesive member 20 along one upper surface of the stack cell 10. In other words, the first roller 321 can be configured to roll from one surface of the guide portion 330 and move along one upper surface of the stack cell 10.

[0060] For example, the first roller 321 may have a circular cross-section so that it can be driven by rolling.

[0061] Here, the first roller 321 may be located below the first gripping unit 311.

[0062] Furthermore, as the first roller 321 moves from one side of the guide portion 330 along one side of the upper surface of the stack cell 10, it presses the adhesive member 20 held by the first gripping unit 311, thereby causing the adhesive member 20 to adhere to one side of the upper surface of the stack cell 10.

[0063] The second roller 322 can be configured to move the other end of the adhesive member 20 along one side of the lower surface of the stack cell 10. In other words, the second roller 322 can be configured to roll from the other side of the guide portion 330 and move along one side of the lower surface of the stack cell 10.

[0064] For example, the second roller 322 may have a circular cross-section so that it can be driven by rolling.

[0065] Here, the second roller 322 may be located above the second gripping unit 312.

[0066] Furthermore, as the second roller 322 moves along one side of the lower surface of the stack cell 10 from the other side of the guide portion 330, it presses the adhesive member 20 held by the second gripping unit 312, thereby causing the adhesive member 20 to adhere to one side of the lower surface of the stack cell 10.

[0067] In other words, the roller section 320 can move the gripping section 310 toward the stack cell 10, thereby allowing the adhesive member 20 gripped by the gripping section 310 to adhere to the stack cell 10.

[0068] The gripping portion 310 and the roller portion 320 are moved to one side or the other by the drive member 340. The drive member 340 will be described later.

[0069] Next, the guide section 330 may include a guide unit 331 and a position adjustment guide 332 to guide the movement path of the roller section 320 based on information about the thickness t of the stack cell 10. Here, information about the thickness t of the stack cell 10 can be received via a plurality of sensors 200. More specifically, the plurality of sensors 200 measure the thickness t of the stack cell 10 and transmit it to a control unit (not shown), the control unit (not shown) provides the information about the thickness t of the stack cell 10 to the guide section 330, and the guide section 330 can receive the information about the thickness t of the stack cell 10.

[0070] The guide unit 331 may be located on the side of the stack cell 10. For example, the guide unit 331 may be in close contact with or adjacent to one side of the stack cell 10.

[0071] Furthermore, for example, the guide unit 331 may be configured to have a thickness corresponding to the minimum thickness of the stack cell 10, or it may be configured to have a thickness thinner than the minimum thickness of the stack cell 10.

[0072] The position adjustment guide 332 is located on one and / or the other side of the guide unit 331 and can adjust the position of the roller portion 320.

[0073] For example, the position adjustment guide 332 is located on only one side of the guide unit 331, allowing the height of the guide portion 330 to be adjusted. Another example is that the position adjustment guide 332 is located on only the other side of the guide unit 331, allowing the height of the guide portion 330 to be adjusted. Yet another example is that, as shown in Figures 4 to 6, the position adjustment guide 332 is located on both the one and the other side of the guide unit 331, allowing the height of the guide portion 330 to be adjusted.

[0074] The following explanation will describe the case where the position adjustment guide 332 is located on one and the other surface of the guide unit 331 as an example.

[0075] The position adjustment guide 332 allows the height of the guide portion 330 to be adjusted to correspond to the thickness t of the stack cell 10 measured by the sensor 200.

[0076] For example, the position adjustment guide 332 can be configured such that a portion of it is inserted into the guide unit 331, and its height is adjusted by a sub-motor provided inside the guide unit 331.

[0077] For example, the position adjustment guide 332 can be configured so that its height is adjusted by a rack and pinion gear. In another example, it can be configured so that its height is adjusted by a cylinder.

[0078] Since such a height adjustment method can be implemented by a height adjustment method that is obvious to those skilled in the art, a more detailed explanation will be omitted.

[0079] On the other hand, the position adjustment guide 332 is located on one and the other side of the guide unit 331 and can be adjusted by an operator, but it is preferable that it is adjusted on both sides from the guide unit 331 by a control unit (not shown) to correspond to the thickness t of the stack cell 10 measured by the sensor 200.

[0080] More specifically, if the guide unit 331 is 7 mm and the thickness t of the stack cell 10 is 11 mm, the position adjustment guide 332 can be used to adjust the height of the guide section 330 to 11 mm, corresponding to the thickness t of the stack cell 10, by raising the position adjustment guide 332 located on one side (upper side) by 2 mm and lowering the position adjustment guide 332 located on the other side (lower side) by 2 mm.

[0081] As a result, the height of the guide portion 330 is adjusted by the position adjustment guide 332, maintaining a state parallel to the upper and lower surfaces of the stack cell 10. When the gripping portion 310 and roller portion 320 move toward the stack cell 10, no difference occurs between the height of the guide portion 330 and the thickness of the stack cell 10, thus preventing defects in the stack cell 10.

[0082] Next, the drive member 340 can be configured to move the gripping portion 310 and the roller portion 320 to one side or the other. For example, the drive member 340 can provide a forward movement that moves the gripping portion 310 and the roller portion 320 to the other side where the stack cell 10 is located (3 o'clock direction with respect to Figure 4), and a backward movement that moves the gripping portion 310 and the roller portion 320 to one side (9 o'clock direction with respect to Figure 4) so ​​that they fall from the stack cell 10.

[0083] More specifically, the drive member 340 may include a cylinder 341, a support rod 342, a first drive rod 343, a second drive rod 344, a first roller rod 345, and a second roller rod 346.

[0084] First, the cylinder 341 can provide a driving force to move the support rod 342, the first drive rod 343, the second drive rod 344, the first roller rod 345, and the second roller rod 346 to one side or the other.

[0085] The support rod 342 can be provided on the other side of the cylinder 341. For example, the support rod 342 can be configured to connect the cylinder 341 to the first drive rod 343, and the cylinder 341 to the second drive rod 344.

[0086] One end of the first drive rod 343 is connected to the support rod 342, and the other end is connected to the first gripping unit 311, thereby providing the first gripping unit 311 with a driving force to move to one side or the other.

[0087] For example, the first drive rod 343 can be connected to the upper side of the support rod 342.

[0088] Furthermore, for example, the first drive rod 343 is connected to the rear side of the first gripping unit 311 and can provide a driving force to move the first gripping unit 311 forward or backward. Thus, the adhesive member gripped by the first gripping unit 311 can be moved toward one side of the upper surface of the stack cell 10.

[0089] Here, the provision of a moving drive force by the first drive rod 343 to the first gripping unit 311 may mean that the first drive rod 343 transmits the moving drive force it receives via the cylinder 341 to the first gripping unit 311.

[0090] One end of the second drive rod 344 is connected to the support rod 342, and the other end is connected to the second gripping unit 312, thereby providing the second gripping unit 312 with a driving force to move to one side or the other.

[0091] For example, the second drive rod 344 can be connected to the lower side of the support rod 342.

[0092] Furthermore, for example, the second drive rod 344 is connected to the rear side of the second gripping unit 312 and can provide a driving force to move the second gripping unit 312 forward or backward. Thus, the adhesive member gripped by the second gripping unit 312 can be moved toward one side of the lower surface of the stack cell 10.

[0093] Here, the provision of a driving force for movement by the second drive rod 344 to the second gripping unit 312 may mean that the second drive rod 344 transmits the driving force it receives via the cylinder 341 to the second gripping unit 312.

[0094] One end of the first roller rod 345 is connected to the first drive rod 343, and the other end is connected to the first roller 321, thereby providing the first roller 321 with a driving force to move to one side or the other.

[0095] For example, the first roller rod 345 can be connected to the first drive rod 343 in a rotated state toward the lower side.

[0096] Furthermore, for example, the first roller rod 345 can rotate inward with respect to the first drive rod 343. For example, the inward rotation of the first roller rod 345 may be in the direction toward the guide portion 330.

[0097] Furthermore, a first connecting member 345a can be interposed between the first roller rod 345 and the first drive rod 343. For example, the first connecting member 345a is a bracket member, and the hole in the bracket member that connects to the first roller rod 345 can be formed as an elongated hole.

[0098] Such a first connecting member 345a is composed of a bracket member having an elongated hole, so that when the first roller rod 345 is rotated inward, it can be driven within the elongated hole.

[0099] As another example, the first connecting member 345a can be composed of an elastic unit, where the elastic unit may be a tension spring. Thus, the first connecting member 345a can provide elastic force to the first roller rod 345 so that when the first roller 321 is driven by the cylinder 341 to roll from one surface of the guide portion 330 to one upper surface of the stack cell 10, it does not detach from one surface of the guide portion 330 and one upper surface of the stack cell 10.

[0100] Furthermore, for example, the first roller rod 345 can be connected to the rear side of the first roller 321 and can provide a driving force to move the first roller 321 forward or backward. Thus, the first roller 321 can be driven to roll along one side of the upper surface of the stack cell 10.

[0101] Here, an air regulator (not shown) can be used to apply air pressure to the first roller rod 345, causing the first roller 321 to roll along one side of the upper surface of the stack cell 10.

[0102] Furthermore, the provision of a driving force for movement by the first roller rod 345 to the first roller 321 may mean that the first roller rod 345 transmits the driving force it receives via the cylinder 341 to the first roller 321.

[0103] One end of the second roller rod 346 is connected to the second drive rod 344, and the other end is connected to the second roller 322, thereby providing the second roller 322 with a driving force to move to one side or the other.

[0104] For example, the second roller rod 346 can be connected to the second drive rod 344 in an upwardly rotated state.

[0105] Furthermore, for example, the second roller rod 346 can rotate inward with respect to the second drive rod 344. For example, the inward rotation of the second roller rod 346 may be in the direction toward the guide portion 330.

[0106] Furthermore, a second connecting member 346a can be interposed between the second roller rod 346 and the second drive rod 344. For example, the second connecting member 346a is a bracket member, and the hole in the bracket member that connects to the second roller rod 346 can be formed as an elongated hole.

[0107] The second connecting member 346a is composed of a bracket member having an elongated hole, so that when the second roller rod 346 is rotated inward, it can be driven within the elongated hole.

[0108] As another example, the second connecting member 346a can be composed of an elastic unit, where the elastic unit may be a tension spring. Thus, the second connecting member 346a can provide elastic force to the first roller rod 345 so as the cylinder 341 drives the second roller 322 to roll from the other surface of the guide portion 330 to one side of the lower surface of the stack cell 10, preventing it from detaching from the other surface of the guide portion 330 and one side of the lower surface of the stack cell 10.

[0109] Furthermore, for example, the second roller rod 346 can be connected to the rear side of the second roller 322 and can provide a driving force to move the second roller 322 forward or backward. Thus, the second roller 322 can be driven to roll along one side of the lower surface of the stack cell 10.

[0110] Here, an air regulator (not shown) can be used to apply air pressure to the second roller rod 346, causing the second roller 322 to roll along one side of the lower surface of the stack cell 10.

[0111] Here, the provision of a driving force for movement by the second roller rod 346 to the second roller 322 may mean that the second roller rod 346 transmits the driving force it receives via the cylinder 341 to the second roller 322.

[0112] It is preferable that multiple taping sections 300 having the above-described configuration are arranged in the intervals between the support bases 100, and it is more preferable that multiple taping sections 300 are arranged on both sides of the stack cell 10.

[0113] For example, the taping portion 300 located on one side can attach the adhesive member 20 from one side, extending beyond the center of the stack cell 10, and the taping portion 300 located on the other side can attach the adhesive member 20 from the other side, extending beyond the center of the stack cell 10. Therefore, the adhesive member 20 on one side and the adhesive member 20 on the other side of the stack cell 10 can overlap in the center.

[0114] This stack cell taping device according to one embodiment of the present invention can tap multiple adhesive members to both sides of the stack cell 10, thereby fixing the stacked electrodes.

[0115] The following describes a stack cell taping method using a stack cell taping device according to one embodiment of the present invention, with reference to Figures 2 to 7.

[0116] The stack cell taping method according to the present invention includes the steps of (S1) arranging stack cells 10 on a plurality of support bases 100, (S2) measuring the thickness t of the stack cells 10 with a sensor 200, (S3) adjusting the height of the guide portion 330 with a position adjustment guide 332 to correspond to the measured thickness t of the stack cells 10, (S4) moving the gripping portion 310 and the roller portion 320 toward the stack cells 10 with a drive member 340, and (S5) attaching the adhesive member 20 gripped by the gripping portion 310 to the side surface of the stack cells 10.

[0117] For example, in step (S2), the sensor 200 can measure the thickness t of the stack cell 10 and transmit the measured thickness t of the stack cell 10 to the control unit (not shown).

[0118] Furthermore, in step (S3), the control unit (not shown) can transmit a signal to the position adjustment guide 332 to adjust the height of the guide unit 330 to correspond to the measured thickness t of the stack cell 10.

[0119] Finally, in step (S5), the gripping portion 310 can be moved forward together with the roller portion 320 by the drive member 340, allowing the adhesive member 20 to be attached to the side surface of the stack cell 10.

[0120] Although specific parts of the present invention have been described in detail above, such specific techniques are merely preferred modes of implementation and do not limit the scope of the present invention. It will be obvious to those skilled in the art that various changes and modifications are possible within the scope of the present invention and its technical concept, and it goes without saying that such variations and modifications also fall within the scope of the appended claims.
