Description

[Technical Field]

[0001] This application claims the benefit of priority based on Korean Patent Application No. 10-2023-0107247 filed on August 16, 2023 and Korean Patent Application No. 10-2024-0103308 filed on August 2, 2024, and all contents disclosed in the above Korean patent applications are incorporated as a part of the present specification.

[0002] The present invention relates to a sealing device, and more particularly to a sealing device capable of sealing a plurality of target surfaces of an object. [Background Art]

[0003] Secondary batteries have high applicability to various product groups and electrical characteristics of high energy density. Such secondary batteries are applied not only to portable electronic devices, but also to electric vehicles or hybrid vehicles driven by electric drive sources, power storage devices and the like. Secondary batteries are attracting attention as a new energy source for improving environmental friendliness and energy efficiency, not only because they have the primary advantage of being able to drastically reduce the use of fossil fuels, but also because they do not generate any by-products resulting from the use of energy.

[0004] In general, a pouch-type secondary battery can be manufactured by stacking or winding an electrode assembly composed of a positive electrode, a negative electrode, and a separation membrane interposed between the positive electrode and the negative electrode, incorporating the assembly into a battery case made of a pouch sheet, and then injecting or impregnating an electrolyte. The pouch-type secondary battery can ensure airtightness by sealing both the upper surface and the lower surface of the pouch sheet protruding along the edge of the secondary battery. However, although such a conventional sealing method can be said to be suitable for thin secondary batteries, secondary batteries that have become thicker due to the manufacture of high-energy secondary batteries have a region requiring sealing formed in a three-dimensional three-dimensional structure. Therefore, when sealed by conventional sealing methods, there is a problem that it is difficult to ensure airtightness of the side portions and corner portions.

[0005] Therefore, there is a need to develop technologies to solve the problems mentioned above. [Overview of the initiative] [Problems that the invention aims to solve]

[0006] The present invention aims to solve the above-mentioned problems, and the problem that the present invention seeks to solve is to provide a sealing device that can seal multiple target surfaces and edges located between multiple target surfaces of an object, which is a three-dimensional three-dimensional structure, at once. [Means for solving the problem]

[0007] A sealing device according to an embodiment of the present invention can seal an object. The sealing device may include a first block provided to seal a plurality of surfaces of the object, including a first sealing surface and a second sealing surface formed along a direction away from the first sealing surface, and a second block driven toward the first block so that the object can be brought 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 may intersect each other.

[0008] The first sealing surface may seal a first surface of the object, and the second sealing surface may seal a second surface formed along a direction away from the first surface.

[0009] The first block may further include a third sealing surface, which is a curved surface, connecting the first sealing surface and the second sealing surface.

[0010] The third sealing surface is provided to seal the edges 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 edges of the target object.

[0011] 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.

[0012] The second block may be driven in a direction inclined toward the first block.

[0013] The second block may be provided to seal the object. The second block may include a first surface formed parallel to the first sealing surface and a second surface that is parallel to the second sealing surface and formed in a direction away from the first surface.

[0014] The second block may further include a third surface, which is a curved surface, connecting the first surface and the second surface.

[0015] The radius of curvature of the third surface may correspond to the radius of curvature of the edge of the object.

[0016] The second block may be driven to a position where the first surface faces the first sealing surface and the second surface faces the second sealing surface.

[0017] The area of ​​the first surface may be even narrower than the area of ​​the first sealing surface, and the area of ​​the second surface may be even narrower than the area of ​​the second sealing surface.

[0018] The second block may further include a second elastic member arranged continuously on the first, second, and third surfaces.

[0019] The first block may have a first guide groove that curves longitudinally from the end of the first sealing surface, and a second guide groove that curves longitudinally from the end of the second sealing surface. The second block may have a first guide projection that protrudes from the end of the first surface and is guided along the second guide groove, and a second guide projection that protrudes from the end of the second surface and is guided along the first guide groove.

[0020] A sealing device according to an embodiment of the present invention can seal an object. The sealing device may include a first block that includes a first sealing surface and a second sealing surface formed along a direction away from the first sealing surface, and is provided to seal a plurality of target surfaces of the object; and a second block that brings the object into close contact with the first block and is driven in a direction intersecting the first block. A first virtual plane perpendicular to the first sealing surface and a second virtual plane perpendicular to the second sealing surface may intersect each other.

[0021] The first sealing surface may seal a first target surface of the object, and the second sealing surface may seal a second target surface located in a direction away from the first target surface.

[0022] The first block may further include a third sealing surface formed of a curved surface that connects between the first sealing surface and the second sealing surface.

[0023] The second block may include a first surface provided to seal the object and formed parallel to the first sealing surface, and a second surface parallel to the second sealing surface and formed in a direction away from the first surface.

[0024] The second block may be driven such that a relative position of the second block with respect to the first block is adjusted according to a size of the object.

[0025] The second block may further include a third surface formed of a curved surface that connects between the first surface and the second surface. Effects of the Invention

[0026] According to a preferred embodiment of the present invention, a plurality of target surfaces of an object which is a three-dimensional structure and an edge located between the plurality of target surfaces can be sealed at one time, and the speed of the sealing process is improved.

[0027] Further, for objects differing in size and shape, the object can be sealed by adjusting only the relative positions between the seal blocks to correspond to the size and shape of the object without replacing the seal blocks. Therefore, the time and cost required for replacing the seal blocks are not required, and the economic efficiency of the sealing process is improved. [Brief Description of the Drawings]

[0030] Preferred embodiments of the present invention will be described in detail below 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. However, the present invention can be realized in a variety of different forms and is not limited to or restricted to the following embodiments.

[0031] In order to clearly explain the present invention, detailed descriptions of parts irrelevant to the description or related prior art that may obscure the essence of the invention are omitted. In this specification, when assigning reference numerals to components of each drawing, the same or similar reference numerals are assigned to components that are the same or similar throughout the specification.

[0032] Furthermore, the terms and words used in this specification and the claims should not be interpreted in a manner limited to their ordinary or dictionary meanings, but rather should be interpreted in a manner consistent with the technical concept of the present invention, in accordance with the principle that inventors can appropriately define the concepts of terms in order to best explain their invention.

[0033] Figure 1 is a schematic perspective view showing the first and second blocks of a sealing device according to the first embodiment of the present invention; Figure 2 is an exploded perspective view of an object as an example; Figure 3 is a perspective view showing the object positioned between the first and second blocks shown in Figure 1; Figure 4 is a perspective view showing the object shown in Figure 3 being sealed by the first and second blocks; and Figures 5a and 5b are schematic front views showing the first and second blocks according to modified examples.

[0034] The sealing device 10 according to the first embodiment of the present invention may be a device for sealing multiple outer surfaces or multiple inner surfaces of an object B (see Figure 3) at once. The sealing device 10 may include a first block 100 and a second block 200.

[0035] Object B may have a shape formed with a predetermined width and thickness. For example, object B may be a secondary battery, but is not limited to that.

[0036] Referring to Figure 2, object B may be a secondary battery comprising an electrode assembly 1, a pouch-type outer material 2 surrounding the electrode assembly 1 and having openings 3 on both sides, and a cover member 4 covering the openings 3 of the outer material 2.

[0037] The sealing device 10 can seal the outer casing material 2 and the cover member 4 of such a secondary battery. For example, the outer casing material 2 may be defined by a laminate sheet 2a surrounding both the electrode assembly 1 and the periphery of the cover member 4. In that case, the sealing device 10 can seal the outer periphery of the cover member 4 and the outer casing material 2.

[0038] The first block 100 can contact the object B and apply heat and pressure to the object B to seal multiple target surfaces S of the object B. The target surfaces S refer to predetermined areas on the outer or inner surface of the object B, which may mean areas where the first block 100 and the second block 200 are in direct contact and perform the sealing process. Taking the secondary battery shown in Figure 2 as an example, the target surfaces S may be areas in the exterior material 2 that are in contact with the outer circumference of the cover member 4.

[0039] The first block 100 may include a folded shape so as to be able 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.

[0040] The first sealing surface 110 can seal the first target surface of object B. The first target surface may be the surface of the target surface S that faces the first sealing surface 110. The first sealing surface 110 is provided so as to face the first target surface and may be formed to be equal to the area of ​​the first target surface, or even wider than the area of ​​the first target surface, so as to be able to seal the entire first target surface.

[0041] The first sealing surface 110 can seal the first target surface by directly contacting it and applying heat and pressure to it. The first target surface may be planar in shape.

[0042] The second sealing surface 120 can seal the second surface of object B. The second surface may be the surface on object surface S that faces the second sealing surface 120. The second surface may be formed along a direction away from the first surface. The first and second surfaces may be surfaces formed continuously with an edge in between. The second surface may form an angle with respect to the first surface, such as a right angle, acute angle, or obtuse angle.

[0043] The second sealing surface 120 is provided facing the second target surface and may be formed to be equal to or wider than the area of ​​the second target surface so as to be able to seal the entire second target surface.

[0044] 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 at a predetermined angle with respect to the first sealing surface 110. For example, as shown in Figure 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 shown in Figure 5a, the angle formed by the first sealing surface 110 and the second sealing surface 120 may be an obtuse angle. As yet another example, as shown in Figure 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 the same as the angle formed by the second target surface with respect to the first target surface.

[0045] Since 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, the first sealing surface 110 and the second sealing surface 120 can seal multiple target surfaces S formed on a three-dimensional object B, rather than a two-dimensional structure on the same plane.

[0046] The second sealing surface 120 can seal the second surface of object B by applying heat and pressure. The second sealing surface 120 may be provided facing the second surface, and the second surface may be planar in shape.

[0047] The first block 100 may further include a third sealing surface 130, which is a curved surface, connecting the first sealing surface 110 and the second sealing surface 120.

[0048] 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, continuously connecting 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.

[0049] The third sealing surface 130 is a curved surface having a predetermined radius of curvature, and can seal the edge of object B by applying heat and pressure to the edge of object B. The radius of curvature of the third sealing surface 130 may be equal to or greater than the radius of curvature of the edge of object B that contacts the third sealing surface 130. Because the radius of curvature of the third sealing surface 130 corresponds to the radius of curvature of the edge of object B, the third sealing surface 130 can surround the edge of object B, and the edge of object B can be in close contact with the third sealing surface 130.

[0050] The third sealing surface 130 can seal the edge connecting the first and second surfaces of object B.

[0051] In other words, the first block 100 can seal the first surface, the second surface, and the edge located between the first and second surfaces of object B all at once.

[0052] The second block 200 can contact object B and apply heat and pressure to object B to seal multiple target surfaces S of object B.

[0053] The second block 200 may be driven to apply pressure to object B while pushing it toward the first block 100 so that object B is in close contact with the first block 100. More specifically, the second block 200 may be driven to apply pressure to object B while pushing it toward the direction in which the first block 100 is located so that object B is in close contact with the first sealing surface 110, the second sealing surface 120, and the third sealing surface 130 of the first block 100.

[0054] The second block 200 may be driven in a direction inclined toward the first block 100. The second block 200 may be positioned at an angle upward away from the first block 100 and driven to move toward the first block 100 when object B is placed on the inner surface of the first block 100. The first block 100 may also be driven to move toward the second block 200, and the first block 100 and the second block 200 may be driven in a direction inclined toward each other. The first block 100 and the second block 200 may be driven not only in a direction inclined toward each other, but also in the up and down, front and back, and left and right directions.

[0055] The second block 200 may be provided to contact object B and apply heat and pressure to multiple target surfaces S of object B to seal them all at once.

[0056] The second block 200 may include the first surface 210 and the second surface 220.

[0057] The second block 200 may be formed to include a folded shape so that it can 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.

[0058] The first surface 210 can seal the third surface of object B. The third surface may be the surface of object S that faces the first surface 210. The first surface 210 may be formed to be equal to or wider than the area of ​​the third surface so as to be able to seal all of the opposing third surfaces.

[0059] The first surface 210 is formed parallel to the first sealing surface 110 and can seal the third surface of object B, which is the opposite surface of the first surface. The first surface 210 may be formed in a planar shape.

[0060] The first surface 210 can seal the third target surface by directly contacting it and applying heat and pressure to it. The third target surface S may also be planar in shape.

[0061] The second block 200 may be driven so that its first surface 210 is positioned opposite 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, thereby pressurizing and sealing the first and third target surfaces of object B.

[0062] The area of ​​the first surface 210 may be equal to the area of ​​the first sealing surface 110, or it may be smaller than the area of ​​the first sealing surface 110, and the area of ​​the second surface 220 may be equal to the area of ​​the second sealing surface 120, or it may be smaller than the area of ​​the second sealing surface 120.

[0063] The second surface 220 may be formed parallel to the second sealing surface 120 and in a direction away from the first surface 210. The second surface 220 can seal the fourth surface, which is the opposite surface of the second surface of object B. The fourth surface may be the surface of object surface S that faces the second surface 220. That is, the second surface 220 may be formed at a predetermined angle with respect to the first surface 210. For example, as shown in Figure 1, the angle formed by the first surface 210 and the second surface 220 may be a right angle. As another example, as shown in Figure 5a, the angle formed by the first surface 210 and the second surface 220 may be an obtuse angle. As yet another example, as shown in Figure 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 the same as the angle formed by the fourth surface with respect to the third surface.

[0064] The second surface 220 can be used to seal the fourth surface of object B by applying heat and pressure. The second surface 220 may also be planar in shape.

[0065] Since the third virtual surface (not shown) perpendicular to the first surface 210 and the fourth virtual surface (not shown) perpendicular to the second surface 220 are formed to intersect each other, the first surface 210 and the second surface 220 are not two-dimensional structures on the same plane, but can seal multiple target surfaces S formed on the three-dimensional object B.

[0066] The second surface 220 can seal the fourth surface of object B. The fourth surface may be formed along a direction away from the third surface. The third and fourth surfaces may be surfaces formed continuously with an edge in between, and the fourth surface may be formed at an angle such as a right angle, acute angle, or obtuse angle with respect to the third surface.

[0067] The second block 200 may be driven so that its second surface 220 is positioned opposite 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, thereby pressurizing and sealing the second and fourth target surfaces of object B.

[0068] The second block 200 may further include a third surface 230, which is a curved surface, connecting the first surface 210 and the second surface 220.

[0069] The third surface 230 can seal the edge of object B. More specifically, the third surface 230 can pressurize and seal the edge connecting the third and fourth surfaces of object B.

[0070] The third surface 230 may be formed on the inner surface of the second block 200 facing the object B. The third surface 230 may be positioned between the first surface 210 and the second surface 220, continuously connecting the first surface 210 and the second surface 220. The third surface 230 may connect the inner ends of the first surface 210 and the second surface 220 to each other.

[0071] The third surface 230 is a curved surface having a predetermined radius of curvature, and can seal the edge of object B by applying heat and pressure to it. The radius of curvature of the third surface 230 may be equal to or greater than the radius of curvature of the edge of object B that is in contact with the third surface 230. Because the radius of curvature of the third surface 230 corresponds to the radius of curvature of the edge of object B, the third surface 230 can surround the edge of object B, and the edge of object B can adhere well to the third surface 230.

[0072] The third surface 230 can seal the edge connecting the third surface and the fourth surface of object B.

[0073] In other words, the second block 200 can seal the third surface, the fourth surface, and the edge located between the third and fourth surfaces of object B all at once.

[0074] Figure 6 is a perspective view showing how an object is sealed by a sealing device according to a second embodiment of the present invention.

[0075] The following explanation will focus on the differences compared to the first embodiment described above, and will refer to the same content as before.

[0076] The sealing device according to the second embodiment of the present invention may further include elastic members 140, 240 provided in at least one of the first block 100 and the second block 200.

[0077] The elastic members 140 and 240 may include flexible materials that are elastically deformable. Furthermore, the elastic members 140 and 240 may include heat-resistant materials that can withstand high temperatures. For example, the elastic members 140 and 240 may include, but are not limited to, at least one of rubber, silicone, and plastic.

[0078] The following explanation will use the example of a case where elastic members 140 and 240 are provided in the first block 100 and the second block 200, respectively.

[0079] The first block 100 may further include the first elastic member 140.

[0080] The first elastic member 140 may be located on the inner surface of the first block 100 facing the object B, and may be continuously arranged along the first sealing surface 110, the third sealing surface 130, and the second sealing surface 120.

[0081] The first elastic member 140 may be arranged on the first sealing surface 110, the second sealing surface 120, and the third sealing surface 130, and may be arranged continuously along the first sealing surface 110, the third sealing surface 130, and the second sealing surface 120.

[0082] The first elastic member 140 ensures that when the first block 100 pressurizes the object B, the pressurizing force of the first block 100 is uniformly transmitted via the first elastic member 140 to the multiple target surfaces S of the object B and the edges located between the multiple target surfaces S, thereby inducing close contact between the first block 100 and the multiple target surfaces S.

[0083] Furthermore, the first elastic member 140 may be located between the first block 100 and the object B. The first elastic member 140 deforms elastically when the first block 100 pressurizes the object B. Therefore, even small gaps between the first block 100 and the object B are filled with the deformed first elastic member 140, and the pressing force of the first block 100 is uniformly transmitted to the multiple object surfaces S and the edges located between the multiple object surfaces S. In particular, the first elastic member 140 can also fill gaps caused by the difference in radius of curvature between the third sealing surface 130 and the edges of the object B, and can effectively transmit the pressing force of the third sealing surface 130 to the edges of the object B.

[0084] The second block 200 may further include a second elastic member 240.

[0085] The second elastic member 240 is located on the inner surface of the second block 200 facing the object B, and may be arranged continuously along the first surface 210, the third surface 230, and the second surface 220.

[0086] The second elastic member 240 may be arranged on the first surface 210, the second surface 220, and the third surface 230, and may be arranged continuously along the first surface 210, the third surface 230, and the second surface 220.

[0087] The second elastic member 240 ensures that when the second block 200 pressurizes the object B, the pressurizing force of the second block 200 is uniformly transmitted via the second elastic member 240 to the multiple target surfaces S of the object B and the edges located between the multiple target surfaces S, thereby inducing close contact between the second block 200 and the multiple target surfaces S.

[0088] Furthermore, the second elastic member 240 may be located between the second block 200 and the object B. The second elastic member 240 deforms elastically when the second block 200 pressurizes the object B. Therefore, even small gaps between the second block 200 and the object B are filled with the second elastic member 240, and the pressing force of the second block 200 is uniformly transmitted to all surfaces of the multiple object surfaces S and the edges located between the multiple object surfaces S. In particular, the second elastic member 240 can also fill gaps caused by the difference in radius of curvature between the third surface 230 and the edges of the object B, and can effectively transmit the pressing force of the third surface 230 to the edges of the object B.

[0089] Figure 7 is a schematic perspective view showing the first and second blocks of a sealing device according to a third embodiment of the present invention, and Figures 8a and 8b are front views illustrating the operation of the guide groove and guide projection shown in Figure 7.

[0090] The following explanation will focus on the differences compared to the first embodiment described above, and will refer to the same content as before.

[0091] The sealing device 10 according to the third embodiment of the present invention can adjust the relative arrangement of the first block 100 and the second block 200 according to the size of the object B. As a result, the sealing device 10 can seal multiple outer surfaces or multiple inner surfaces of an object B of various sizes at once.

[0092] More specifically, guide grooves 112, 122 may be formed in either the first block 100 or the second block 200, and guide projections 211, 221 that are guided along the guide grooves 112, 122 may be formed in the other.

[0093] In the following explanation, we will use the case where guide grooves 112 and 122 are formed in the first block 100 and guide protrusions 211 and 221 are formed in the second block 200 as an example.

[0094] The first block 100 may have a first guide groove 112 and a second guide groove 122 formed therein.

[0095] The first guide groove 112 may be formed to curve inward from the outer end of the first sealing surface 110 in the longitudinal direction of the first sealing surface 110.

[0096] The second guide groove 122 may be formed to curve inward from the outer end of the second sealing surface 120 in the longitudinal direction of the second sealing surface 120.

[0097] The second block 200 may have a first guide projection 211 and a second guide projection 221 formed thereon.

[0098] The first guide projection 211 may be formed to protrude outward from the outer end of the first surface 210 in the longitudinal direction of the first surface 210.

[0099] The second guide projection 221 may be formed to protrude outward from the outer end of the second surface 220 in the longitudinal direction of the second surface 220.

[0100] The first block 100 and the second block 200 can be separated by adjusting the distance between them to correspond to the size of object B located between them. The first block 100 and the second block 200 can move toward or away from each other, crossing each other, depending on the size of object B. The first guide projection 211 can be inserted into the second guide groove 122 and moved along the second guide groove 122 to guide the first block 100 and the second block 200 to cross each other, and the second guide projection 221 can be inserted into the first guide groove 112 and moved along the first guide groove 112 to guide the first block 100 and the second block 200 to guide the first block 100 and the second block 200 to cross each other.

[0101] Figure 9 is a schematic perspective view showing the first and second blocks of a sealing device according to a fourth embodiment of the present invention, and Figure 10 is a perspective view showing how the first and second blocks shown in Figure 9 seal an object.

[0102] The following explanation will focus on the differences compared to the first embodiment described above, and will refer to the same content as before.

[0103] The first block 100 and the second block 200 of the sealing device according to the fourth embodiment of the present invention can approach each other in directions that pass each other and intersect, thereby pressurizing the object B. That is, instead of being driven toward the first block 100, the second block 200 can be driven in a direction that intersects with the first block 100.

[0104] The second block 200 may be driven to move in a direction that passes and intersects with the first block 100, thereby applying pressure to object B.

[0105] When object B is pressurized, the first block 100 and the second block 200 may partially overlap each other in the longitudinal direction of object B. However, the first block 100 and the second block 200 do not need to overlap each other in the direction of pressurization applied to object B.

[0106] The second block 200 may be positioned at a location diagonally upward from the first block 100. The second block 200 may be driven to move toward object B when object B is placed on the inner surface of the first block 100. Since the first block 100 and the second block 200 move past each other and cross paths, they can move without obstructing each other's direction of travel. This increases the size range of object B that can be sealed between the first block 100 and the second block 200.

[0107] When the first block 100 and the second block 200 move across each other, their opposing parts may come into contact with each other. That is, one surface of the first block 100 and one surface of the second block 200 that are opposite each other with respect to the longitudinal direction of object B may come into contact with each other when object B is pressurized.

[0108] The first block 100 and the second block 200 can adjust their relative positions according to the size and shape of object B. For example, the first block 100 and the second block 200 can seal object B by adjusting their relative positions, distances, etc., to correspond to the shape of object B.

[0109] Figure 11 is a schematic perspective view showing the first and second blocks of a sealing device according to a fifth embodiment of the present invention.

[0110] The following explanation will focus on the differences compared to the fourth embodiment described above, and will refer to the same content as before.

[0111] The sealing device according to the fifth embodiment of the present invention may be provided with at least one of the first block 100 and the second block 200, and the first block 100 and the second block 200 may be arranged alternately with respect to the longitudinal direction of the object B.

[0112] For example, if multiple second blocks 200 are provided, the first block 100 is positioned between the multiple second blocks 200 and can seal multiple target surfaces S of the object B at once together with the second blocks 200. The multiple second blocks 200 may be arranged parallel to each other, or they may be arranged separated from each other by a predetermined distance. The first block 100 may be positioned between the second blocks 200.

[0113] The second block 200 and the first block 100 can move in a direction that is inclined so as to pass each other and intersect, and can also move in a direction that is either moving towards each other or away from each other.

[0114] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and various implementations are possible within the equivalent scope of the technical concept of the present invention and the appended claims by persons with ordinary skill in the art to which the present invention pertains.
