[0003] Technology field

[0004] The present invention relates to a sealing device, and more particularly, to a sealing device capable of sealing multiple target surfaces of an object.

[0005] Secondary batteries are highly applicable to a wide range of product groups and possess electrical properties that enable high energy density. These batteries are used not only in portable electronic devices but also in electric or hybrid vehicles powered by electrical power sources, as well as in power storage devices. Secondary batteries are attracting attention as a new energy source for environmental friendliness and energy efficiency, not only because they can dramatically reduce fossil fuel use, but also because they produce no byproducts from energy use.

[0006] In general, pouch-type secondary batteries can be manufactured by stacking or winding an electrode assembly composed of a positive electrode, a negative electrode, and a separator interposed between the positive and negative electrodes, embedding it in a battery case of a pouch sheet, and then injecting or impregnating it with an electrolyte. The pouch-type secondary battery can be made airtight by sealing the upper and lower surfaces of the pouch sheet protruding along the edge of the secondary battery. However, although this existing sealing method is suitable for thin secondary batteries, as high-energy secondary batteries are manufactured, the secondary batteries become thicker, and the area requiring sealing is formed as a three-dimensional stereoscopic structure, so there is a problem that it is difficult to ensure airtightness in the side and corner areas when sealing using the existing sealing method.

[0007] Therefore, there is a need to develop technology to solve the above problems.

[0008] The present invention is intended to solve the above problems, and the problem that the present invention seeks to solve is to provide a sealing device capable of simultaneously sealing a plurality of target surfaces of an object that is a three-dimensional three-dimensional structure and an edge located between the target surfaces.

[0009] A sealing device according to an embodiment of the present invention can seal an object. The sealing device can include a first block having a first sealing surface and a second sealing surface formed in a direction away from the first sealing surface and configured to seal a plurality of target surfaces of the object; and a second block driven toward the first block so as to bring the object into close contact with the first block. A first virtual surface perpendicular to the first sealing surface and a second virtual surface perpendicular to the second sealing surface can intersect with each other.

[0010] The first sealing surface can seal a first target surface of the object, and the second sealing surface can seal a second target surface formed along a direction away from the first target surface.

[0011] The first block may further include a third sealing surface formed as a curved surface, connecting the first sealing surface and the second sealing surface.

[0012] The third sealing surface is provided to seal an edge connecting the plurality of target surfaces, and the radius of curvature of the third sealing surface may correspond to the radius of curvature of the edge of the target.

[0013] The first block may further include a first elastic member disposed on the first sealing surface, the second sealing surface, and the third sealing surface.

[0014] The second block can be driven in an oblique direction toward the first block.

[0015] The second block may be configured to seal the object. The second block may include a first surface formed parallel to the first sealing surface; and a second surface formed parallel to the second sealing surface and facing away from the first surface.

[0016] The second block may further include a third surface formed as a curved surface, connecting the first surface and the second surface.

[0017] The radius of curvature of the third surface may correspond to the radius of curvature of the corner of the object.

[0018] The second block can be driven so that the first surface faces the first sealing surface and the second surface faces the second sealing surface.

[0019] The area of ​​the first surface may be narrower than the area of ​​the first sealing surface, and the area of ​​the second surface may be narrower than the area of ​​the second sealing surface.

[0020] The second block may further include a second elastic member continuously arranged on the first side, the second side, and the third side.

[0021] The first block may be formed with a first guide groove recessed in the longitudinal direction from an end of the first sealing surface; and a second guide groove recessed in the longitudinal direction from an end of the second sealing surface. The second block may be formed with a first guide protrusion protruding from an end of the first surface and guided along the first guide groove; and a second guide protrusion protruding from an end of the second surface and guided along the second guide groove.

[0022] A sealing device according to an embodiment of the present invention can seal an object. The sealing device may include a first block having a first sealing surface and a second sealing surface formed in a direction away from the first sealing surface and configured to seal a plurality of target surfaces of the object; and a second block that presses the object against the first block and is driven in a direction intersecting with the first block. A first virtual surface perpendicular to the first sealing surface and a second virtual surface perpendicular to the second sealing surface may intersect each other.

[0023] The first sealing surface can seal a first target surface of the object, and the second sealing surface can seal a second target surface located in a direction away from the first target surface.

[0024] The first block may further include a third sealing surface formed as a curved surface, connecting the first sealing surface and the second sealing surface.

[0025] The second block may include a first surface formed parallel to the first sealing surface and configured to seal the object; and a second surface formed parallel to the second sealing surface and facing away from the first surface.

[0026] The second block can be driven so that its relative position with respect to the first block is adjusted according to the size of the object.

[0027] The second block may further include a third surface formed as a curved surface, connecting the first surface and the second surface.

[0028] According to a preferred embodiment of the present invention, a plurality of target surfaces of a three-dimensional solid structure and edges located between the target surfaces can be sealed at once, thereby improving the speed of the sealing process.

[0029] In addition, since objects of different sizes and shapes can be sealed by adjusting only the relative positions between the sealing blocks to match the size and shape of the object without replacing the sealing blocks, the time and cost required for replacing the sealing blocks are unnecessary, and thus the economic efficiency of the sealing process can be improved.

[0046] A sealing device (10) according to a first embodiment of the present invention may be a device for sealing multiple outer surfaces or multiple inner surfaces of an object (B) (see FIG. 3) at once. The sealing device (10) may include a first block (100) and a second block (200).

[0047] The object (B) may have a shape formed with a predetermined width and thickness. For example, the object (B) may be a secondary battery. However, the present invention is not limited thereto.

[0048] Referring to FIG. 2, the object (B) may be a secondary battery including an electrode assembly (1), a pouch-shaped outer material (2) surrounding the electrode assembly (1) and having openings (3) formed on both sides, and a cover member (4) covering the openings (3) of the outer material (2).

[0049] The sealing device (10) can seal the outer periphery (2) and the cover member (4) of such a secondary battery to each other. For example, the outer periphery (2) can be defined by a laminate sheet (2a) surrounding the periphery of the electrode assembly (1) and the cover member (4). In this case, the sealing device (10) can seal the outer periphery of the cover member (4) and the outer periphery (2) to each other.

[0050] The first block (100) comes into contact with the object (B) and can seal a plurality of target surfaces (S) of the object (B) by applying heat and pressure to the object (B). The target surface (S) may refer to a predetermined area on the outer or inner surface of the object (B), which is an area where the first block (100) and the second block (200) directly come into contact and seal. Taking the secondary battery illustrated in Fig. 2 as an example, the target surface (S) may be an area that comes into contact with the outer periphery of the cover member (4) among the outer materials (2).

[0051] The first block (100) may include a bent shape so as to seal multiple target surfaces (S) of the object (B) at once. More specifically, the first block (100) may include a first sealing surface (110) and a second sealing surface (120). The first sealing surface (110) and the second sealing surface (120) may be formed on the inner surface of the first block (100) facing the object (B).

[0052] The first sealing surface (110) can seal the first target surface of the object (B). The first target surface may be a surface of the target surface (S) that faces the first sealing surface (110). The first sealing surface (110) is provided to face the first target surface, and may be formed to have an area equal to or wider than the area of ​​the first target surface so as to be able to seal the entire first target surface.

[0053] The first sealing surface (110) can seal the first target surface by applying heat and pressure to the first target surface by making direct contact with the first target surface. The first target surface may have a flat shape.

[0054] The second sealing surface (120) can seal the second target surface of the object (B). The second target surface may be a surface of the target surface (S) that faces the second sealing surface (120). The second target surface may be formed in a direction away from the first target surface. The first target surface and the second target surface may be surfaces formed continuously with an edge therebetween. The second target surface may form an angle, such as a right angle, an acute angle, or an obtuse angle, with respect to the first target surface.

[0055] The second sealing surface (120) is provided to face the second target surface, and can be formed to have an area equal to or wider than the area of ​​the second target surface so that the entire second target surface can be sealed.

[0056] The second sealing surface (120) may be formed along a direction away from the first sealing surface (110). The second sealing surface (120) may be formed to form a predetermined angle with respect to the first sealing surface (110). For example, as illustrated in FIG. 1, the angle formed by the first sealing surface (110) and the second sealing surface (120) may be a right angle. As another example, as illustrated in FIG. 5A, the angle formed by the first sealing surface (110) and the second sealing surface (120) may be an obtuse angle. As another example, as illustrated in FIG. 5B, the angle formed by the first sealing surface (110) and the second sealing surface (120) may be an acute angle. The angle formed by the second sealing surface (120) with respect to the first sealing surface (110) may be formed to be the same as the angle formed by the second target surface with respect to the first target surface.

[0057] The first virtual surface (111) perpendicular to the first sealing surface (110) and the second virtual surface (121) perpendicular to the second sealing surface (120) are formed to intersect each other, so that the first sealing surface (110) and the second sealing surface (120) can seal a plurality of target surfaces (S) formed on a three-dimensional, three-dimensional object (B) rather than a two-dimensional structure on the same plane.

[0058] The second sealing surface (120) can seal the second target surface of the object (B) by applying heat and pressure to the second target surface. The second sealing surface (120) can be provided to face the second target surface, and the second target surface can have a flat shape.

[0059] The first block (100) connects the first sealing surface (110) and the second sealing surface (120), and may further include a third sealing surface (130) formed in a curved shape.

[0060] The third sealing surface (130) may be formed on the inner surface of the first block (100) facing the object (B). The third sealing surface (130) may be positioned between the first sealing surface (110) and the second sealing surface (120) to continuously connect the first sealing surface (110) and the second sealing surface (120). The third sealing surface (130) may connect the inner ends of the first sealing surface (110) and the second sealing surface (120) to each other.

[0061] The third sealing surface (130) is formed as a curved surface having a predetermined radius of curvature, and can seal the corner of the object (B) by applying heat and pressure to the corner of the object (B). The radius of curvature of the third sealing surface (130) may be equal to or larger than the radius of curvature of the corner of the object (B) that contacts the third sealing surface (130). Since the radius of curvature of the third sealing surface (130) corresponds to the radius of curvature of the corner of the object (B), the third sealing surface (130) can wrap the corner of the object (B), and the corner of the object (B) can be in close contact with the third sealing surface (130).

[0062] The third sealing surface (130) can seal the corner connecting the first target surface and the second target surface of the object (B).

[0063] That is, the first block (100) can seal the first target surface, the second target surface, and the corners located between the first and second target surfaces of the object (B) at once.

[0064] The second block (200) comes into contact with the object (B) and can seal multiple target surfaces (S) of the object (B) by applying heat and pressure to the object (B).

[0065] The second block (200) can be driven to push and press the object (B) toward the first block (100) so that the object (B) comes into close contact with the first block (100). More specifically, the second block (200) can be driven to push and press the object (B) toward the direction in which the first block (100) is located so that the object (B) comes into close contact with the first sealing surface (110), the second sealing surface (120), and the third sealing surface (130) of the first block (100).

[0066] The second block (200) can be driven in an oblique direction toward the first block (100). The second block (200) is positioned at an oblique upward position relative to the first block (100), and can be driven to move toward the first block (100) when an object (B) is placed on the inner surface of the first block (100). The first block (100) can also be driven to move toward the second block (200), and the first block (100) and the second block (200) can be driven to move in an oblique direction toward each other. The first block (100) and the second block (200) can be driven not only in an oblique direction toward each other, but also in an up-down direction, a forward-backward direction, and a left-right direction.

[0067] The second block (200) may be provided to contact the target object (B) and apply heat and pressure to multiple target surfaces (S) of the target object (B) to seal them at once.

[0068] The second block (200) may include a first side (210) and a second side (220).

[0069] The second block (200) may be formed to include a bent shape so as to be able to seal multiple target surfaces (S) of the object (B) at once. The second block (200) may include a first surface (210) and a second surface (220). The first surface (210) and the second surface (220) may be formed on the inner surface of the second block (200) facing the object (B).

[0070] The first surface (210) can seal the third target surface of the object (B). The third target surface can be a surface among the target surfaces (S) that faces the first surface (210). The first surface (210) can be formed to have an area equal to or wider than the area of ​​the third target surface so that it can seal all of the facing third target surfaces.

[0071] The first surface (210) is formed parallel to the first sealing surface (110) and can seal the third target surface, which is the opposite surface of the first target surface of the object (B). The first surface (210) can be formed in a flat shape.

[0072] The first surface (210) can seal the third target surface by applying heat and pressure to the third target surface by making direct contact with the third target surface. The third target surface (S) may have a flat shape.

[0073] The second block (200) can be driven so that the first surface (210) faces the first sealing surface (110) of the first block (100). The first surface (210) and the first sealing surface (110) are driven toward each other, and can pressurize and seal the first target surface and the third target surface of the object (B).

[0074] The area of ​​the first surface (210) may be equal to or narrower than the area of ​​the first sealing surface (110), and the area of ​​the second surface (220) may be equal to or narrower than the area of ​​the second sealing surface (120).

[0075] The second surface (220) is formed parallel to the second sealing surface (120) and may be formed in a direction away from the first surface (210). The second surface (220) may seal a fourth target surface, which is an opposite surface of the second target surface of the object (B). The fourth target surface may be a surface of the target surfaces (S) that faces the second surface (220). That is, the second surface (220) may be formed to form a predetermined angle with respect to the first surface (210). For example, as illustrated in FIG. 1, the angle formed by the first surface (210) and the second surface (220) may be a right angle. As another example, as illustrated in FIG. 5A, the angle formed by the first surface (210) and the second surface (220) may be an obtuse angle. As another example, as illustrated in FIG. 5b, the angle formed by the first surface (210) and the second surface (220) may be an acute angle. The angle formed by the second surface (220) with respect to the first surface (210) may be formed to be the same as the angle formed by the fourth target surface with respect to the third target surface.

[0076] The second surface (220) can seal the fourth target surface of the object (B) by applying heat and pressure to the fourth target surface. The second surface (220) may have a flat shape.

[0077] A third virtual surface (not shown) perpendicular to the first surface (210) and a fourth virtual surface (not shown) perpendicular to the second surface (220) are formed to intersect each other, so that the first surface (210) and the second surface (220) can seal a plurality of target surfaces (S) formed on a three-dimensional structure object (B) rather than a two-dimensional structure on the same plane.

[0078] The second surface (220) can seal the fourth target surface of the object (B). The fourth target surface can be formed in a direction away from the third target surface. The third target surface and the fourth target surface can be continuously formed surfaces with an edge between them, and the fourth target surface can be formed at an angle such as a right angle, an acute angle, or an obtuse angle with respect to the third target surface.

[0079] The second block (200) can be driven so that the second surface (220) faces the second sealing surface (120) of the first block (100). The second surface (220) and the second sealing surface (120) are driven toward each other, and can pressurize and seal the second target surface and the fourth target surface of the object (B).

[0080] The second block (200) connects the first surface (210) and the second surface (220) and may further include a third surface (230) formed as a curved surface.

[0081] The third surface (230) can seal the edge of the object (B). More specifically, the third surface (230) can pressurize and seal the edge connecting the third target surface and the fourth target surface of the object (B).

[0082] The third surface (230) can be formed on the inner surface facing the object (B) of the second block (200). The third surface (230) can be positioned between the first surface (210) and the second surface (220) to continuously connect the first surface (210) and the second surface (220). The third surface (230) can connect the inner ends of the first surface (210) and the second surface (220) to each other.

[0083] The third surface (230) is formed as a curved surface having a predetermined radius of curvature, and can seal the corner of the object (B) by applying heat and pressure to the corner of the object (B). The radius of curvature of the third surface (230) may be equal to or larger than the radius of curvature of the corner of the object (B) that contacts the third surface (230). Since the radius of curvature of the third surface (230) corresponds to the radius of curvature of the corner of the object (B), the third surface (230) can wrap the corner of the object (B), and the corner of the object (B) can be closely attached to the third surface (230).

[0084] The third surface (230) can seal the corner connecting the third target surface and the fourth target surface of the object (B).

[0085] That is, the second block (200) can seal the third target surface, the fourth target surface, and the corners located between the third and fourth target surfaces of the object (B) at once.

[0086] Fig. 6 is a perspective view showing an object being sealed by a sealing device according to a second embodiment of the present invention.

[0087] Below, the differences compared to the first embodiment will be explained, and the same content will be cited.

[0088] The sealing device according to the second embodiment of the present invention may further include an elastic member (140)(240) provided in at least one of the first block (100) and the second block (200).

[0089] The elastic member (140)(240) may include a flexible material that can be elastically deformed. In addition, the elastic member (140)(240) may include a heat-resistant material that can withstand high temperatures. For example, the elastic member (140)(240) may include at least one material selected from the group consisting of rubber, silicone, and plastic. However, the present invention is not limited thereto.

[0090] Hereinafter, an example will be described in which an elastic member (140)(240) is provided in each of the first block (100) and the second block (200).

[0091] The first block (100) may further include a first elastic member (140).

[0092] The first elastic member (140) is located on the inner surface of the first block (100) facing the object (B), and can be continuously arranged along the first sealing surface (110), the third sealing surface (130), and the second sealing surface (120).

[0093] The first elastic member (140) is arranged on the first sealing surface (110), the second sealing surface (120), and the third sealing surface (130), and can be arranged continuously along the first sealing surface (110), the third sealing surface (130), and the second sealing surface (120).

[0094] The first elastic member (140) can ensure that when the first block (100) presses the object (B), the pressing force of the first block (100) is uniformly transmitted to the plurality of target surfaces (S) of the object (B) and the corners located between the plurality of target surfaces (S) through the first elastic member (140), and can induce the first block (100) and the plurality of target surfaces (S) to come into close contact.

[0095] In addition, the first elastic member (140) can be positioned between the first block (100) and the object (B). As the first block (100) presses the object (B), the first elastic member (140) can be elastically deformed. Therefore, even a small gap between the first block (100) and the object (B) is filled with the deformed first elastic member (140), so that the pressing force of the first block (100) can be uniformly transmitted to the plurality of object surfaces (S) and the corners located between the plurality of object surfaces (S). In particular, the first elastic member (140) can also fill the gap created due to the difference in the radius of curvature of the third sealing surface (130) and the corner of the object (B), so that the pressing force of the third sealing surface (130) can be well transmitted to the corner of the object (B).

[0096] The second block (200) may further include a second elastic member (240).

[0097] The second elastic member (240) is located on the inner surface of the second block (200) facing the object (B), and can be continuously arranged along the first surface (210), the third surface (230), and the second surface (220).

[0098] The second elastic member (240) is arranged on the first surface (210), the second surface (220), and the third surface (230), and can be arranged continuously along the first surface (210), the third surface (230), and the second surface (220).

[0099] The second elastic member (240) can ensure that when the second block (200) presses the object (B), the pressing force of the second block (200) is uniformly transmitted to the plurality of target surfaces (S) of the object (B) and the corners located between the target surfaces (S) through the second elastic member (240), and can induce the second block (200) and the plurality of target surfaces (S) to come into close contact.

[0100] In addition, the second elastic member (240) can be positioned between the second block (200) and the object (B). As the second block (200) presses the object (B), the second elastic member (240) can be elastically deformed. Therefore, even a small gap between the second block (200) and the object (B) is filled with the second elastic member (240), so that the pressing force of the second block (200) can be uniformly transmitted to all surfaces of the plurality of object surfaces (S) and the corners located between the object surfaces (S). In particular, the second elastic member (240) can also fill the gap caused by the difference in the radius of curvature of the corner of the third surface (230) and the object (B), so that the pressing force of the third surface (230) can be well transmitted to the corner of the object (B).

[0101] FIG. 7 is a perspective view schematically illustrating the first block and the second block of the sealing device according to the third embodiment of the present invention, and FIGS. 8a and 8b are front views for explaining the operation of the guide groove and guide protrusion illustrated in FIG. 7.

[0102] Below, the differences compared to the first embodiment will be explained, and the same content will be cited.

[0103] According to the third embodiment of the present invention, the sealing device (10) can adjust the mutual arrangement of the first block (100) and the second block (200) to suit the size of the object (B). Accordingly, the sealing device (10) can seal multiple outer surfaces or multiple inner surfaces of the object (B) at once for objects (B) having various sizes.

[0104] In more detail, a guide groove (112)(122) may be formed in one of the first block (100) and the second block (200), and a guide protrusion (211)(221) guided along the guide groove (112)(122) may be formed in the other.

[0105] Hereinafter, an example will be described in which a guide groove (112)(122) is formed in a first block (100) and a guide protrusion (211)(221) is formed in a second block (200).

[0106] In the first block (100), a first guide groove (112) and a second guide groove (122) can be formed.

[0107] The first guide groove (112) can be formed to be recessed along the longitudinal direction of the first sealing surface (110) from the outer end of the first sealing surface (110).

[0108] The second guide groove (122) can be formed to be recessed along the length direction of the second sealing surface (120) from the outer end of the second sealing surface (120).

[0109] In the second block (200), a first guide protrusion (211) and a second guide protrusion (221) can be formed.

[0110] The first guide protrusion (211) can be formed to protrude along the longitudinal direction of the first surface (210) in an outward direction from the outer end of the first surface (210).

[0111] The second guide protrusion (221) can be formed to protrude along the longitudinal direction of the second surface (220) in an outward direction from the outer end of the second surface (220).

[0112] The distance between the first block (100) and the second block (200) can be adjusted to match the size of the object (B) located between the first block (100) and the second block (200). The first block (100) and the second block (200) can move closer or further apart while intersecting with each other depending on the size of the object (B). In order for the first block (100) and the second block (200) to intersect with each other, the first guide protrusion (211) can be inserted into the second guide groove (122) and guided while moving along the second guide groove (122), and the second guide protrusion (221) can be inserted into the first guide groove (112) and guided while moving along the first guide groove (112).

[0113] FIG. 9 is a perspective view schematically illustrating a first block and a second block of a sealing device according to a fourth embodiment of the present invention, and FIG. 10 is a perspective view illustrating the first block and the second block illustrated in FIG. 9 sealing an object.

[0114] Below, the differences compared to the first embodiment will be explained, and the same content will be cited.

[0115] The first block (100) and the second block (200) of the sealing device according to the fourth embodiment of the present invention can pressurize the object (B) by approaching in directions that intersect each other. That is, instead of the second block (200) being driven toward the first block (100), it can be driven in a direction that intersects the first block (100).

[0116] The second block (200) can be driven to move in a direction intersecting with the first block (100) and pressurize the object (B).

[0117] When the object (B) is pressurized, the first block (100) and the second block (200) may partially overlap each other with respect to the longitudinal direction of the object (B). In addition, the first block (100) and the second block (200) may not overlap each other with respect to the direction of pressing against the object (B).

[0118] The second block (200) can be positioned at an obliquely upwardly spaced position relative to the first block (100). When the object (B) is secured on the inner surface of the first block (100), the second block (200) can be driven to move toward the object (B). The first block (100) and the second block (200) move so as to intersect each other in an alternating manner, so that they can move without interfering with each other's moving direction. As a result, the size range of the object (B) that can be sealed between the first block (100) and the second block (200) can be further expanded.

[0119] The first block (100) and the second block (200) can move while intersecting each other and having their facing portions touch each other when moving. That is, one side of the first block (100) and one side of the second block (200), which face each other in the longitudinal direction of the object (B), can touch each other when the object (B) is pressed.

[0120] The relative positions of the first block (100) and the second block (200) can be adjusted according to the size and shape of the object (B). For example, the first block (100) and the second block (200) can seal the object (B) by adjusting the relative positions, distances, etc. to match the shape of the object (B).

[0121] Fig. 11 is a perspective view schematically illustrating the first block and the second block of the sealing device according to the fifth embodiment of the present invention.

[0122] Below, the differences compared to the previous fourth embodiment will be explained, and the same content will be cited.

[0123] A sealing device according to a fifth embodiment of the present invention may include at least one of a first block (100) and a second block (200) in multiple numbers. In addition, the first block (100) and the second block (200) may be arranged alternately with respect to the longitudinal direction of the object (B).

[0124] For example, when a plurality of second blocks (200) are provided, the first block (100) is positioned between the plurality of second blocks (200) and can seal a plurality of target surfaces (S) of the object (B) at once together with the second blocks (200). The plurality of second blocks (200) can be arranged parallel to each other and can be arranged to be spaced apart from each other by a predetermined distance. The first block (100) can be positioned between the second blocks (200).

[0125] The second block (200) and the first block (100) can move in an oblique direction so as to intersect each other in an alternating manner, and can move in a direction closer to or farther away from each other.

[0126] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and various embodiments are possible within the scope equivalent to the technical idea of ​​the present invention and the claims to be described below by a person having ordinary skill in the art to which the present invention pertains.
