Description

Riveting device for cylindrical batteries

[0001] The present invention relates to a riveting device used to manufacture cylindrical batteries.

[0002] Generally, secondary batteries are classified according to the shape of the battery case into cylindrical and prismatic batteries, in which the electrode assembly is embedded in a cylindrical or prismatic metal can, and pouch-type batteries, in which the electrode assembly is embedded in a pouch-type case made of aluminum laminate sheet.

[0003] A cylindrical battery generally includes a cylindrical can (14), a rivet (131), and a gasket (132) (see FIG. 1).

[0004] In the process of manufacturing a cylindrical battery, a rivet (131) is combined with a gasket (132). Then, the rivet-gasket assembly (13), in which the rivet (131) and the gasket (132) are combined, is riveted into a center hole formed on one side of a can (14). The riveting device is a device for riveting the rivet-gasket assembly (13) into the center hole of the can (14).

[0005] FIG. 1 briefly illustrates the process of riveting a rivet-gasket assembly (13) into the center hole of a can (14).

[0006] In FIG. 1, a rivet (131) and a gasket (132) ((a)) separated from each other are combined to form a rivet-gasket assembly (13) ((b)). With the rivet-gasket assembly (13) fitted into the center hole of a can (14), a pressure member (16) is inserted and positioned inside the can (14), and a fixing plate (or base plate) (17) is positioned on one side of the rivet-gasket assembly (13) outside the can (14). Then, the pressure member (16) and / or the fixing plate (17) move toward the rivet-gasket assembly (13) and press the rivet-gasket assembly (13) ((c)). Due to the pressure of the pressure member (16), the rivet-gasket assembly (13) is deformed and is fastened (riveting) into the center hole of the can (14) ((d)).

[0007] In FIG. 1, the process of joining the rivet (131) and the gasket (132) and the process of fitting the rivet-gasket assembly (13) into the center hole of the can (14) are omitted.

[0008] During the process of joining the rivet-gasket assembly (13) with the center hole of the can (14), assembly defects may occur due to poor tolerance between the rivet-gasket assembly (13) and the can (14). Since such assembly defects weaken the quality and durability of the secondary battery, they need to be improved.

[0009] FIG. 2 illustrates a state in which the central axis line (e.g., vertical central axis line) of the pressurizing member (16) and the central axis line (e.g., vertical central axis line) of the rivet-gasket assembly (13) connected to the can (14) are misaligned. This state is caused by assembly tolerances, etc., described later. The assembly tolerances include, for example, the fixing plate tolerance and / or can tolerance, etc., described later.

[0010] The above assembly tolerances are explained as follows.

[0011] Generally, the fixed plate (17) has a can placement section (not labeled) where a can (14) is placed.

[0012] The can placement portion may be a certain area on one side of the fixed plate (17), or may be formed in a groove shape or the like on one side of the fixed plate (17).

[0013] During the manufacturing process of the fixing plate (17) or the process of installing the fixing plate (17) on the riveting device, a tolerance (referred to as ‘fixing plate tolerance’ in this specification) may occur because the can placement portion is not placed in the correct position.

[0014] Alternatively, during the process of placing the can (14) in the can placement section, the can (14) may not be placed in the correct position in the can placement section, and a tolerance (referred to as 'can tolerance' in this specification) may occur. The can tolerance may be greater if the fixing plate (17) shakes during the process of the pressing member (16) pressing the rivet-gasket assembly (13).

[0015] Due to the above assembly tolerance (fixing plate tolerance and / or can tolerance, etc.), when the pressing member (16) is pressed, an assembly defect may occur between the rivet-gasket assembly (13) and the can (14), or a crack may occur in the can (14).

[0016] Therefore, during the process of riveting the rivet-gasket assembly (13) and the can (14), the assembly tolerance must be minimized so that the pressure received by the rivet-gasket assembly (13) by the pressurizing member (16) can be applied evenly and uniformly to the entire rivet-gasket assembly (13).

[0017] In order for the above assembly tolerance to be minimized, the center axis of the pressure member (16) and the center axis of the rivet-gasket assembly (13) need to be placed on the same axis.

[0018] Korean Patent Publication No. 10-2023-0078926 (Publication Date: June 5, 2023) presents a riveting structure for electrode terminals, but this aims to increase space efficiency within the battery can by improving the electrode terminal structure of the battery cell and does not present a method to minimize the aforementioned assembly tolerance.

[0019] Therefore, there is a need for a device or component that ensures the rivet-gasket assembly (13) is accurately fastened to the center of the can (14) (i.e., the central axis of the pressure member (16) and the central axis of the rivet-gasket assembly (13) are aligned on the same axis).

[0020] The objective of the present invention is to provide a riveting device for a cylindrical battery that improves assembly defects between a rivet-gasket assembly and a can by minimizing assembly tolerances during the process of riveting the rivet-gasket assembly and the can.

[0021] The aforementioned objective of the present invention is achieved by the specific details described below.

[0022] A riveting device for a cylindrical battery according to an example of an embodiment of the present invention comprises a clamping part, a pressure assembly, and a support assembly. The clamping part holds a cylindrical can. The pressure assembly includes a pressure member that presses a rivet assembly placed on the can. The support assembly includes a support member that supports the rivet assembly. When the pressure member presses the rivet assembly, the center axis of the pressure member, the center axis of the rivet assembly, and the center axis of the support member are positioned on the same axis.

[0023] Specifically, the clamping member includes a clamping member and a connecting member. When the can assembly is placed at a preset position by the rotation of the index member, the clamping member moves toward the can assembly to grasp the can. The connecting member is connected to the clamping member. When the clamping member grasps the can, the center axis of the rivet assembly placed on the can coincides with the center axis of the pressing member and the center axis of the support member.

[0024] Specifically, before the pressing member presses the rivet assembly to rivet, the pressing member moves to push the can assembly placed on the index member toward the support assembly, thereby moving the can assembly by a preset distance.

[0025] Specifically, the pressure assembly comprises a pressure member, a moving member, a pressure guide member, and a pressure frame. The moving member is connected to the pressure member. The pressure guide member guides the movement of the pressure member and the moving member. The pressure frame supports the pressure member, the moving member, and the pressure guide member.

[0026] Specifically, the pressure member comprises a first pressure member and a second pressure member. The first pressure member contacts a rivet assembly. The second pressure member is inserted into a groove formed in the first pressure member and is connected to a movable member. When one side of the second pressure member is inserted into the groove of the first pressure member, the center axis of the first pressure member is positioned on the same axis as the center axis of the second pressure member.

[0027] Specifically, the pressure frame includes a top plate member having a through hole formed therein. A moving member or a pressure member can move toward a can assembly by passing through the through hole formed in the top plate member.

[0028] Specifically, the first pressing member is disposed on the upper surface of the top plate member surrounding the through hole of the top plate member. The second pressing member or the moving member penetrates the through hole of the top plate member.

[0029] Specifically, the pressure frame further includes a plurality of side plate members and a bottom plate member. The plurality of side plate members support a top plate member, and the bottom plate member supports the side plate members and the top plate member. The bottom plate member is provided with a through hole through which a pressure member and a movable member pass.

[0030] Specifically, the second pressing member or the moving member penetrates the through hole of the lower plate member.

[0031] Specifically, the pressure guide member is positioned to surround the pressure member and the moving member.

[0032] Specifically, the support assembly includes a support member and a cam member. The support member is movable in one direction. The cam member is connected to the support member and is movable in a direction orthogonal to the one direction.

[0033] Specifically, when the cam member moves in a direction orthogonal to one direction, the support member moves in one direction.

[0034] Specifically, the cam member includes a path portion. The path portion is a hole or groove having a preset length in a diagonal direction.

[0035] Specifically, the support assembly further includes a roller member disposed in the path section. While disposed in the path section, the roller member is capable of moving diagonally along the shape of the path section.

[0036] Specifically, the rotational center axis of the roller member is connected to the support member.

[0037] Specifically, when the cam member moves in a direction orthogonal to one direction, the roller member moves in a diagonal direction along the shape of the path section.

[0038] Specifically, when the cam member moves back and forth in the left and right directions, the roller member moves back and forth between the first and second points of the path section arranged diagonally, and the roller member moves by a preset distance in the up and down direction.

[0039] Specifically, the support assembly further includes a support guide portion that guides the movement of the support member.

[0040] Specifically, the support assembly further includes a cam moving part that moves a cam member.

[0041] A riveting device for a cylindrical battery according to an example of an embodiment of the present invention improves assembly defects between a rivet-gasket assembly and a can by minimizing assembly tolerances during the process of fastening the rivet-gasket assembly and the can.

[0042] A riveting device for a cylindrical battery according to an example of an embodiment of the present invention comprises a clamping part, a pressure assembly, and a support assembly, so that when assembling a rivet-gasket assembly and a can, the center axis of the pressure member, the center axis of the rivet-gasket assembly, and the center axis of the support member are arranged on the same axis, thereby having the effect of improving assembly defects.

[0058] Hereinafter, a riveting device for a cylindrical battery according to an example of an embodiment of the present invention will be described.

[0059] Hereinafter, the ‘riveting device for a cylindrical battery according to an example of an embodiment of the present invention’ may be briefly referred to as the ‘riveting device of the present invention’.

[0060] Generally, a cylindrical battery includes a cylindrical can (14), a rivet (131), and a gasket (132) (see FIG. 1).

[0061] The can (14) accommodates an electrode assembly inside.

[0062] In the process of manufacturing a cylindrical battery (see FIG. 1), the cylindrical can (14) is provided with a one-sided hole (141) formed on one side and a other-sided hole (142) formed on the other side. The one-sided and the other-sided points to opposite sides in the longitudinal direction of the can (14).

[0063] The above-mentioned one-sided hole (141) is formed at the center of one side of the can (14).

[0064] The above-mentioned one-sided hole (141) can be named the 'center hole (141)'.

[0065] The diameter of the center hole (141) is formed to be smaller than the diameter of the other hole (142).

[0066] A rivet-gasket assembly (13), described later, is fitted into the center hole (141).

[0067] And, the pressure member (31) described later is inserted into the other hole (142) to apply pressure to the rivet-gasket assembly (13).

[0068] The above other hole (142) may be named 'pressure part insertion hole (142)'.

[0069] The rivet (131) is fastened to the center hole (141) of the can (14). The rivet (131) can serve as an electrode in the cylindrical battery.

[0070] The gasket (132) is joined with the rivet (131) and seals the gap between the rivet (131) and the center hole (141) of the can (14).

[0071] The riveting device (10) of the present invention is a device for riveting a rivet-gasket assembly (13) into a center hole (141) of a can (14).

[0072] FIG. 3 schematically shows the riveting device (10) of the present invention.

[0073] The riveting device (10) of the present invention includes a frame (11), an index member (12), a clamping part (20), a pressure assembly (30), and a support assembly (40).

[0074] The frame (11) supports various components such as an index member (12), a pressure assembly (30), and a support assembly (40) provided in the riveting device (10) of the present invention.

[0075] The frame (11) can be formed by combining various structures and is not limited to a specific shape, and can be formed in various forms according to the user's requirements.

[0076] The riveting device (10) of the present invention is composed of an index structure.

[0077] Generally, the index structure represents a device in which a plurality of can assemblies (15) are arranged at a predetermined interval on a rotating disc, and when each can assembly (15) reaches a certain point due to the rotation of the disc, structures arranged on one side and the other side (e.g., the upper side and the lower side) of the can assembly (15) move to rivet the can assembly (15).

[0078] In this specification, the can assembly (15) indicates that the rivet-gasket assembly (13) is fitted into a center hole (141) formed on one side of the can (14) before the can (14) and the rivet-gasket assembly (13) are riveted by a pressurizing member (31) described later.

[0079] The riveting device (10) of the present invention is a device for riveting a can assembly (15), and represents a device for riveting a rivet-gasket assembly (13) fitted into a center hole (141) of a can (14) using a clamping part (20), a pressure assembly (30), and a support assembly (40) described later to rivet the rivet-gasket assembly (13) to one side of a can (14).

[0080] And the above rivet-gasket assembly (13) represents a combination of a rivet (131) and a gasket (132). Generally, the rivet-gasket assembly (13) represents a combination in which the body constituting the rivet (131) is inserted into the center hole (141) of the gasket (132). To elaborate, the rivet-gasket assembly (13) is a structure in which the gasket (132) surrounds the outer surface of the body of the rivet (131).

[0081] In this specification, the process of joining the rivet (131) and the gasket (132) and the process of fitting the rivet-gasket assembly (13) into the center hole (141) of the can (14) are performed by known technology, and a description thereof is omitted.

[0082] The rivet-gasket assembly (13) can be named a ‘rivet assembly (13)’.

[0083] The index member (12) corresponds to the aforementioned rotating disc.

[0084] The index member (12) represents a rotatable plate member and is not limited to a circular shape.

[0085] The riveting device (10) of the present invention includes components that allow the index member (12) to rotate.

[0086] A can assembly (15) is placed on the edge side of the index member (12). The edge side refers not only to the edge but also to the area adjacent to the edge.

[0087] As the index member (12) rotates, when the can assembly (15) is placed at a preset position, the pressure assembly (30) and the support assembly (40) placed on one side and the other side (e.g., the upper side and the lower side) of the can assembly (15) are operated.

[0088] The clamping part (20) holds the can assembly (15) (specifically, the can (14)) placed on the index member (12) and fixes the can assembly (15) (see FIG. 3 and FIG. 4).

[0089] The clamping part (20) is connected to the support assembly (40) described later.

[0090] As the index member (12) rotates, when the can assembly (15) is placed at a preset position, the clamping member (20) operates to hold the can assembly (15).

[0091] The clamping part (20) includes a clamping member (21) and a connecting member (22).

[0092] The clamping member (21) holds the can assembly (15) (specifically, the can (14)).

[0093] A plurality of clamping members (21) are provided.

[0094] Multiple clamping members (21) are spaced apart at a preset distance.

[0095] A plurality of clamping members (21) are spaced apart from the can (14) at a preset distance, and as the index member (12) rotates, the can assembly (15) is positioned at a preset position, and the plurality of clamping members (21) move toward the can (14) and grasp the side of the can (14).

[0096] In the case where there are two clamping members (21), each clamping member (21) moves to grasp the outer surface of the can (14) on the left and right sides of the can (14). The outer surface of the can (14) represents an outer surface (or outer circumference) connecting one side of the can (14) and the other side.

[0097] When there are three or more clamping members (21), the clamping members (21) are arranged at equal intervals in the circumferential direction along the outer surface of the can (14) and move toward the can (14) to grasp the outer surface of the can (14).

[0098] The clamping member (21) aligns the rivet assembly (13) so that the center of the rivet assembly (13) placed on the can (14) coincides with the center of the pressing member (31) and the center of the support member (41) described later (see FIG. 4).

[0099] Specifically, when a plurality of clamping members (21) grip the can (14), the center axis line (Z line in FIG. 4) of the rivet assembly (13) placed on the can (14) coincides with the center axis line (Z line) of the pressing member (31) and the center axis line (Z line) of the support member (41).

[0100] That is, when multiple clamping members (21) hold the can (14), the center axis line (Z line) of the can (14), the center axis line (Z line) of the rivet assembly (13), the center axis line (Z line) of the pressing member (31), and the center axis line (Z line) of the support member (41) are arranged on the same axis.

[0101] Accordingly, during the process of riveting the can (14) and the rivet assembly (13) by pressure, the assembly tolerance described in the background art is minimized, and the pressure received by the rivet assembly (13) by the pressure member (31) is applied evenly and uniformly to the entire rivet assembly (13).

[0102] As illustrated in FIG. 4, the central axis line (Z line) of the can (14) represents a line passing through the center of the can (14) in the longitudinal direction of the can (14). And, the central axis line (Z line) of the rivet assembly (13) represents a line passing through the center of the rivet assembly (13) (specifically, the rivet (131) or the gasket (132)) in a direction orthogonal to the radial direction of the rivet assembly (13) (specifically, the rivet (131) or the gasket (132)). And, the central axis line (Z line) of the pressure member (31) represents a line passing through the center of the pressure member (31) in the longitudinal direction of the pressure member (31). And, the central axis line (Z line) of the support member (41) represents a line passing through the center of the support member (41) in the longitudinal direction of the support member (41).

[0103] The shape and material of the clamping member (21) are not limited to a specific shape and material. If the clamping member (21) can align the position of the can (14) to a preset position, the shape and material of the clamping member (21) can be formed with various shapes and materials.

[0104] The connecting member (22) is positioned between the clamping member (21) and the support assembly (40) described later, thereby connecting the clamping member (21) and the support assembly (40).

[0105] That is, one side of the connecting member (22) is connected to the clamping member (21), and the other side of the connecting member (22) is connected to the support assembly (40).

[0106] A single connecting member (22) may be composed of multiple components. Multiple components may be formed into a link structure to form a single connecting member (22). Each component may be movable. The movement includes rotation.

[0107] Additionally, each of the multiple clamping members (21) can be connected to a connecting member (22). In this case, the connecting member (22) may be composed of multiple components.

[0108] The connecting member (22) can move. As the connecting member (22) moves, the clamping member (21) moves. The movement includes rotation.

[0109] The riveting device (10) of the present invention includes components that allow the connecting member (22) to move.

[0110] The connecting member (22) can be formed in a rod shape and a plate shape, and can be formed in a shape including a rod shape and a plate shape.

[0111] The pressure assembly (30) presses the rivet assembly (13) to rivet the rivet assembly (13) to the can (14) (see FIG. 6 and FIG. 8).

[0112] Specifically, by the pressure of the pressure assembly (30), the rivet assembly (13) is riveted into the center hole (141) formed on one side of the can (14).

[0113] The pressurizing assembly (30) is placed on one side (e.g., the lower side) of the can assembly (15).

[0114] The pressure assembly (30) is inserted into the interior of the can (14) through the pressure part insertion hole (142) of the can (14) and pressurizes the rivet assembly (13).

[0115] In the can assembly (15) placed on the index member (12), the rivet assembly (13) inserted into the center hole (141) of the can (14) faces the support assembly (40), and the pressure part insertion hole (142) of the can (14) faces the pressure assembly (30).

[0116] The pressure assembly (30) includes a pressure member (31), a moving member (32), a pressure guide member (33), and a pressure frame (34).

[0117] The pressing member (31) is a member that contacts the rivet assembly (13) and presses the rivet assembly (13).

[0118] The pressure member (31) can move.

[0119] The pressure member (31) moves and penetrates the pressure part insertion hole (142) of the can (14) and is inserted into the interior of the can (14), and presses the rivet assembly (13) inside the can (14).

[0120] The pressure member (31) can be formed in a rod shape with a preset length.

[0121] The pressure member (31) includes one side and the other side. The one side and the other side point to opposite sides in the longitudinal direction.

[0122] One side of the pressure member (31) is in contact with the rivet assembly (13), and the other side of the pressure member (31) is connected to the moving member (32).

[0123] According to an example of an embodiment of the present invention, the pressurizing member (31) may include a first pressurizing member (311) and a second pressurizing member (312) (see FIG. 8).

[0124] The first pressure member (311) and the second pressure member (312) can move.

[0125] The first pressure member (311) and the second pressure member (312) can be formed in a rod shape having a preset length.

[0126] Each of the first pressure member (311) and the second pressure member (312) includes one side and the other side. The one side and the other side point to opposite sides in the longitudinal direction.

[0127] The first pressure member (311) may have a space inside. The second pressure member (312) is formed with a size that can be inserted into the space. Accordingly, the second pressure member (312) can be moved and positioned in the space.

[0128] One side of the first pressure member (311) faces toward the rivet assembly (13), and the other side of the first pressure member (311) faces toward the second pressure member (312).

[0129] The other side of the first pressure member (311) has an opening formed therein, and the opening is in communication with a space formed inside the first pressure member (311).

[0130] That is, the first pressure member (311) includes a groove formed by being sunk to a predetermined depth toward one side through an opening formed on the other side. A second pressure member (312) can be inserted into the groove.

[0131] According to an example of an embodiment of the present invention, the bottom of the groove formed in the first pressure member (311) may be formed in a funnel shape (not shown). To explain further, at the bottom of the groove formed in the first pressure member (311), the radius of the groove decreases toward one side.

[0132] And, one side of the second pressure member (312) may be formed in a pointed or small spherical shape so as to be fitted into the bottom (funnel shape) of the groove formed in the first pressure member (311).

[0133] As a result, when one side of the second pressure member (312) is inserted into the groove of the first pressure member (311), the center axis of the first pressure member (311) is positioned on the same axis as the center axis of the second pressure member (312).

[0134] One side of the first pressure member (311) can be in contact with the rivet assembly (13).

[0135] Specifically, the second pressure member (312) moves toward the first pressure member (311), and one side of the second pressure member (312) is inserted into the groove of the first pressure member (311) through an opening formed on the other side of the first pressure member (311).

[0136] Then, the second pressing member (312) continues to move and presses one side of the first pressing member (311) inside the groove of the first pressing member (311). Due to the pressure of the second pressing member (312), the first pressing member (311) and the second pressing member (312) move together, and one side of the first pressing member (311) comes into contact with the rivet assembly (13).

[0137] The continued pressure of the second pressure member (312) is transmitted to the first pressure member (311), and by the pressure of the first pressure member (311), the rivet assembly (13) is riveted to one side of the can (14) while being inserted into the center hole (141) of the can (14). By riveting, the rivet assembly (13) is fixed to one side of the can (14). When riveted, the rivet assembly (13) is supported by a support member (41) described later.

[0138] As described above, when the second pressing member (312) moves to press the first pressing member (311) in the groove of the first pressing member (311), the center axis of the first pressing member (311) and the center axis of the second pressing member (312) are positioned on the same axis. Additionally, the center axis of the pressing member (31) is positioned on the same axis as the center axis of the rivet assembly (13).

[0139] The other side of the pressure member (31) or the other side of the second pressure member (312) is connected to the moving member (32).

[0140] The moving member (32) is not limited to a specific shape and is connected to the pressing member (31) or the second pressing member (312).

[0141] As the moving member (32) moves, the pressing member (31) or the second pressing member (312) moves.

[0142] The riveting device (10) of the present invention includes components (or devices) that enable a moving member (32) to move. The components (or devices) may include a motor device or a cylinder device operated by pneumatic or hydraulic pressure. The components (or devices) are made of known technology, and a description thereof is omitted.

[0143] The pressure guide member (33) guides the movement of the pressure member (31) or the second pressure member (312) and the moving member (32).

[0144] The pressure guide member (33) may be provided in multiple numbers. That is, the pressure guide member (33) may be formed from one or more pressure guide members (33) (components).

[0145] The pressure guide member (33) may be positioned adjacent to the pressure member (31) or the second pressure member (312) and the moving member (32), and may be positioned (or formed) to surround the pressure member (31) or the second pressure member (312) and the moving member (32).

[0146] That is, the pressurizing member (31) or the second pressurizing member (312) and the moving member (32) can be placed inside (or inside) the pressurizing guide member (33).

[0147] The pressure member (31) or the second pressure member (312) can slide in one direction while in contact with the pressure guide member (33).

[0148] The pressure guide member (33) is formed to guide the movement of the pressure member (31) or the second pressure member (312) and is not limited to a specific shape.

[0149] Additionally, the pressure guide member (33) can guide the center axis of the pressure member (31) (including the first pressure member (311) and the second pressure member (312)) to be aligned with the center axis of the rivet assembly (13).

[0150] The pressure guide member (33) is positioned between the upper plate member (341) and the lower plate member (343) described later, and is connected to the upper plate member (341) and the lower plate member (343).

[0151] Specifically, one side of the pressure guide member (33) is connected to the upper plate member (341), and the other side of the pressure guide member (33) is connected to the lower plate member (343). The connection can be made by a fastening member (e.g., a bolt, nut, screw, etc.) or by welding, etc.

[0152] A space of a predetermined size is formed between the pressure guide member (33), the upper plate member (341), and the lower plate member (343). In the space, all and / or part of the aforementioned pressure member (31) or the second pressure member (312) and the moving member (32) may be disposed.

[0153] The pressure member (31), the moving member (32), and the pressure guide member (33) are placed on the pressure frame (34).

[0154] The pressure frame (34) is placed on the frame (11) and supports the pressure member (31), the moving member (32), and the pressure guide member (33).

[0155] The pressure frame (34) includes a top plate member (341), a side plate member (342), and a bottom plate member (343).

[0156] The top plate member (341) supports the pressure member (31) (specifically, the first pressure member (311)).

[0157] The first pressure member (311) is placed on the top plate member (341).

[0158] The top plate member (341) can be formed into a plate shape having a preset thickness and width.

[0159] The top plate member (341) is not limited to a specific shape.

[0160] Steps, grooves, and holes may be formed on the upper surface, lower surface, and / or side of the upper plate member (341).

[0161] The top plate member (341) can be formed by combining multiple components.

[0162] The top plate member (341) may have a through hole through which the pressure member (31) can pass. If the top plate member (341) is composed of multiple components, an opening through which the pressure member (31) can pass may be provided in the center.

[0163] The moving member (32) and / or the pressing member (31) connected to the moving member (32) can move toward the can assembly (15) by passing through a through hole (or opening) formed in the top plate member (341).

[0164] In an example of an embodiment comprising a first pressure member (311) and a second pressure member (312), the pressure member (31) penetrating the through hole (or opening) of the top plate member (341) represents the second pressure member (312). In this example of an embodiment, the first pressure member (311) is disposed on the upper surface of the top plate member (341) surrounding the through hole (or opening) of the top plate member (341).

[0165] The side plate member (342) is positioned between the top plate member (341) and the bottom plate member (343) and is connected to the top plate member (341) and the bottom plate member (343).

[0166] Specifically, one side of the side plate member (342) is connected to the top plate member (341), and the other side of the side plate member (342) is connected to the bottom plate member (343). The connection can be made by fastening members (e.g., bolts and nuts, screws, etc.) or by welding, etc.

[0167] By means of the side plate member (342), a space of a predetermined size is formed between the top plate member (341) and the bottom plate member (343). All and / or part of the aforementioned pressure member (31), pressure guide member (33), and movable member may be disposed in the space.

[0168] The side plate member (342) may be formed in a plate shape with a preset thickness and width or in a rod shape with a preset length.

[0169] The side plate member (342) is not limited to a specific shape.

[0170] Steps, grooves, and holes may be formed on the upper surface, lower surface and / or side of the side plate member (342).

[0171] The side plate member (342) can be formed by combining multiple components.

[0172] Additionally, a plurality of side plate members (342) may be provided. One side of each of the plurality of side plate members (342) is connected to the top plate member (341), and the other side is connected to the bottom plate member (343).

[0173] The bottom plate member (343) supports the side plate member (342) and the top plate member (341).

[0174] The top plate member (341) and the side plate member (342) are placed on the bottom plate member (343).

[0175] The bottom plate member (343) can be formed into a plate shape having a preset thickness and width.

[0176] The bottom plate member (343) is not limited to a specific shape.

[0177] Steps, grooves, and holes may be formed on the upper surface, lower surface, and / or side of the lower plate member (343).

[0178] The lower plate member (343) can be formed into a single plate shape.

[0179] Additionally, as illustrated in FIGS. 3, 6, and 8, the lower plate member (343) may be formed by combining a plurality of components (e.g., plate shapes) (343a, 343b, 343c). The combination is made using known technology.

[0180] The lower plate member (343) may have a through hole through which the pressing member (31) and / or moving member (32) can pass.

[0181] In the case where the lower plate member (343) is composed of a plurality of components (lower plate members) (343a, 343b, 343c), the component (lower plate member) (343b) positioned in the center may have a through hole through which the pressing member (31) and / or the moving member (32) can pass.

[0182] The moving member (32) and / or the pressing member (31) connected to the moving member (32) can move toward the upper plate member (341) and the can assembly (15) by passing through the through hole formed in the lower plate member (343).

[0183] In an example of an embodiment including a first pressure member (311) and a second pressure member (312), the pressure member (31) penetrating the through hole of the lower plate member (343) represents the second pressure member (312). In this example of an embodiment, the first pressure member (311) is positioned on the upper surface of the upper plate member (341) surrounding the through hole (or opening) of the upper plate member (341).

[0184] Meanwhile, the pressure assembly (30) performs the role of preventing the index member (12) from being damaged.

[0185] FIG. 5 schematically shows the bending of an index member (12) in a conventional riveting device.

[0186] Referring to FIG. 5, in a conventional riveting device, the fixed plate (17) is connected to the index member (12). Therefore, when the pressing member (31) presses the rivet-gasket assembly (13) placed on the can (14), the pressing force of the pressing member (31) is also transmitted to the fixed plate (17) and the index member (12). Accordingly, the index member (12) can be bent with respect to the center of the index member (12).

[0187] Due to continuous use, the index member (12) of the conventional riveting device may bend and break.

[0188] Additionally, as the index member (12) bends, the assembly tolerance described in the background art becomes larger, and assembly defects may become more severe.

[0189] To solve the above problem, the pressure assembly (30) can move the can assembly (15) placed on the index member (12) away from the support assembly (40) by a preset distance (L1) (upward side in FIG. 6). Accordingly, the pressure of the pressure member (31) can be prevented from being applied to the index member (12).

[0190] In the riveting device (10) of the present invention, the can assembly (15) is placed on the index member (12) but is in a seated state without being constrained by any force applied by the index member (12).

[0191] And, the can assembly (15) is held by a clamping member (21). The clamping member (21) is connected to a support assembly (40).

[0192] Accordingly, when the pressurizing assembly (30) pushes the can assembly (15) toward the support assembly (40), the can assembly (15) moves toward the support assembly (40) and is separated from its original position by a preset distance (L1).

[0193] In this state, even if the pressure assembly (30) (specifically, the pressure member (31)) applies high pressure to the rivet assembly (13), the high pressure is not transmitted to the index member (12).

[0194] Before the pressurizing member (31) of the pressurizing assembly (30) applies high pressure to the rivet assembly (13) to rivet, the pressurizing member (31) can move to slightly push the can assembly (15) toward the support assembly (40) (upward side in FIG. 6) (applying a weak force) and move the can assembly (15) by a preset distance (L1).

[0195] The support assembly (40) serves to support the rivet assembly (13) on the opposite side of the pressure assembly (30) when the pressure assembly (30) (specifically, the pressure member (31)) presses the rivet assembly (13) placed in the center hole (141) of the can (14) (see FIG. 8 and FIG. 9).

[0196] When the can assembly (15) moves to a preset position by rotating the index member (12), a support assembly (40) is placed on one side (e.g., the upper side) of the can assembly (15), and a pressure assembly (30) is placed on the other side (e.g., the lower side) of the can assembly (15). At this time, the support assembly (40) (specifically, the support member (41)) faces the rivet assembly (13) exposed to the outside of the can assembly (15), and the pressure assembly (30) (specifically, the pressure member (31)) faces the pressure part insertion hole (142) of the can (14).

[0197] The support assembly (40) includes a support member (41), a support guide part (42), a cam member (43), a cam moving part (44), and a support member (45).

[0198] The support member (41) supports the rivet assembly (13) when the pressurizing member (31) presses the rivet assembly (13) inside the can (14).

[0199] The support member (41) can be formed into a rod shape with a preset length.

[0200] The support member (41) includes one side and the other side. The one side and the other side point to opposite sides in the longitudinal direction.

[0201] One side of the support member (41) can be in contact with the rivet assembly (13), and the other side of the support member (41) is connected to the cam member (43).

[0202] When the pressing member (31) of the pressing assembly (30) moves to press the rivet assembly (13), the center axis of the pressing member (31), the center axis of the rivet assembly (13), and the center axis of the support member (41) are arranged on the same axis.

[0203] FIG. 7 illustrates an exemplary case in which the height of the fixing plate (17) in a conventional riveting device is constant, so the fixing plate (17) cannot support the can (14) depending on the height difference.

[0204] A conventional riveting device has a structure in which the fixed plate (17) cannot move and remains fixed (see FIG. 7). Therefore, if the size of the can (14) (e.g., vertical length) changes, the position of the pressing member (16) changes, and the fixed plate (17) is unable to support the rivet assembly (13). The fixed plate (17) corresponds to the support member (41) of the riveting device (10) of the present invention. In FIG. 7, L2 represents the distance over which the position of the pressing member (16) changes.

[0205] To solve this problem, conventionally, the user had to change the position of the fixing plate (17) whenever the size of the can (14) was changed. This lowers the production efficiency of the cylindrical battery.

[0206] The riveting device (10) of the present invention can quickly change the position of the support member (41), thereby increasing production efficiency.

[0207] The support member (41) can move in one direction and in the opposite direction of said one direction. For example, as shown in FIG. 9, the support member (41) can move up and down by means of a cam member (43) described later.

[0208] When the support member (41) moves, the center axis of the support member (41) does not deviate from the center axis of the rivet assembly (13).

[0209] That is, when the support member (41) moves, it moves in one direction and in the opposite direction of the one direction along the central axis of the rivet assembly (13).

[0210] The support guide part (42) holds the support member (41) when the support member (41) moves, allowing the support member (41) to move stably without shaking, and guides the movement of the support member (41).

[0211] The support guide (42) guides the movement of the support member (41) so that the center axis of the support member (41) does not deviate from the center axis of the rivet assembly (13).

[0212] By means of the support guide part (42), the center axis of the support member (41) is positioned on the same axis as the center axis of the pressing member (31) and the center axis of the rivet assembly (13).

[0213] In addition, the support guide part (42) holds the support member (41) and thus serves to restrict the rotation of the support member (41).

[0214] One side of the support guide portion (42) is connected to the support member (41), and the other side of the support guide portion (42) is connected to the support member (45) described later. The connection can be made using various known fastening members and fastening methods.

[0215] The support guide (42) can be, for example, a known LM guide (Linear Motion Guide).

[0216] The support guide part (42) includes a first member (421) and a second member (422).

[0217] The first member (421) is connected to the support member (41).

[0218] The first member (421) can move in one direction and in the opposite direction of the one direction together with the support member (41).

[0219] The first member (421) can be formed into a rod shape with a preset length, as shown in FIG. 8, and can also be formed into various other shapes.

[0220] The first member (421) can be formed with a step in the longitudinal direction.

[0221] Alternatively, steps, grooves, and holes may be formed on the upper surface, lower surface and / or side of the first member (421).

[0222] According to an example of an embodiment of the present invention, the first member (421) may be a plurality of. Additionally, one first member (421) may be formed by combining a plurality of components.

[0223] One side of the first member (421) is connected to the support member (41), and the other side of the first member (421) is movably connected to the second member (422).

[0224] The second member (422) is connected to the first member (421) and guides the movement of the support member (41).

[0225] The second member (422) can be formed in a block shape having a predetermined length in one direction.

[0226] One side (or one surface) of the second member (422) is connected to the first member (421) (specifically, the other side), and the other side (or other surface) of the second member (422) is connected to and fixed to one side of the support member (45) described later.

[0227] The first member (421) (specifically, the other side) can move in one direction and in the opposite direction of the one direction (up and down direction, vertical direction in FIG. 8) while connected to one side (or one surface) of the second member (422).

[0228] According to an example of an embodiment of the present invention, the second member (422) may be a plurality of.

[0229] Multiple second members (422) are arranged side by side in one direction and spaced apart from each other by a preset distance.

[0230] Additionally, one second member (422) can be formed by combining multiple components.

[0231] The cam member (43) is connected to the support member (41). Specifically, the cam member (43) is connected to the other side of the support member (41).

[0232] The cam member (43) can move in a direction orthogonal to the direction of movement of the support member (41). That is, the cam member (43) can move in a direction orthogonal to one direction.

[0233] For example, the cam member (43) can move in the left and right directions. The movement of the cam member (43) is achieved by the cam moving part (44) described later.

[0234] When the cam member (43) moves in a direction orthogonal to one direction, the support member (41) moves in one direction.

[0235] The cam member (43) can move the support member (41) in one direction and in the opposite direction of the one direction (up and down direction in FIG. 8 and FIG. 9).

[0236] For example, when the cam member (43) moves in the left-right direction, the support member (41) moves in the up-down direction.

[0237] The cam member (43) includes a path portion (431). In other words, a path portion (431) is formed in the cam member (43).

[0238] The path portion (431) may be a hole formed in the cam member (43), as illustrated in FIGS. 8 and 9. The hole has a predetermined length in a diagonal direction. The width of the hole may be formed at a constant value. The width of the hole represents the length of the hole in a direction orthogonal to the diagonal direction.

[0239] The path portion (431) is not limited to a hole shape. For example, the path portion (431) may be a recess formed to a predetermined depth from one side of the cam member (43). The recess has a predetermined length in a diagonal direction.

[0240] The support assembly (40) of the present invention includes a roller member (432).

[0241] The roller member (432) represents a known roller.

[0242] The roller member (432) is placed in the path section (431).

[0243] The roller member (432) can move diagonally along the shape of the path section (431) while positioned in the path section (431).

[0244] According to an example of an embodiment of the present invention, a rail member (not shown) of a preset length may be disposed in the path section (431) to reduce the movement resistance of the roller member (432). The roller member (432) may roll along the rail member.

[0245] The roller member (432) is connected to the support member (41).

[0246] Specifically, the rotational center axis (432a) of the roller member (432) is connected to the other side of the support member (41). By connecting the support member (41) to the roller member (432) positioned on the cam member (43), the support member (41) is connected to the cam member (43).

[0247] The rotational center axis (432a) of the roller member (432) does not rotate when the wheel of the roller member (432) rotates. Accordingly, the support member (41) connected to the rotational center axis (432a) of the roller member (432) also does not rotate.

[0248] A bearing (e.g., a ball bearing) may be placed between the rotational center axis (432a) of the roller member (432) and the wheel. To elaborate, the bearing may be inserted into the center hole (141) of the wheel, and the rotational center axis (432a) of the roller member (432) may be placed in the center hole (141) of the bearing. As a result, even if the wheel of the roller member (432) rotates, the rotational center axis (432a) of the roller member (432) may not rotate.

[0249] Furthermore, since the support member (41) is connected to the aforementioned support guide part (42) (specifically, the first member (421)), the rotation of the support member (41) is limited.

[0250] The correlation between the movement of the cam member (43) and the movement of the support member (41) is explained as follows (see FIG. 9).

[0251] When the cam member (43) moves in the left and right directions, the roller member (432) moves diagonally along the shape of the path section (431) in the path section (431).

[0252] The path section (431) includes a first point (431a) and a second point (431b) at both ends in the longitudinal direction.

[0253] In the path section (431) formed by a diagonal line, the first point (431a) is the upper end point of the diagonal line, and the second point (431b) is the lower end point of the diagonal line.

[0254] As the cam member (43) moves back and forth in the left and right directions, the roller member (432) moves back and forth between the first point (431a) and the second point (431b) of the path section (431). At this time, the roller member (432) moves by a preset distance (L3) in the up and down direction.

[0255] As the roller member (432) moves in the up and down direction, the support member (41) connected to the roller member (432) also moves in the up and down direction by a preset distance (L3) (see FIG. 9).

[0256] When the support member (41) moves in the up and down direction, the support guide part (42) restricts the rotation of the support member (41) and guides the support member (41) to move stably in the up and down direction without shaking.

[0257] Accordingly, even if the support member (41) moves in the up and down direction, the center axis of the support member (41) is positioned on the same axis as the center axis of the pressing member (31) and the center axis of the rivet assembly (13).

[0258] The cam moving part (44) moves the cam member (43). Specifically, the cam moving part (44) can move the cam member (43) in the left and right directions.

[0259] The cam moving part (44) includes a cam driving part (441) that moves the cam member (43).

[0260] The cam drive unit (441) may be a motor device, as shown in FIG. 9, and may be a pneumatic or hydraulic cylinder device.

[0261] The cam moving part (44) includes connecting components (not shown) that connect the cam driving part (441) and the cam member (43) to each other.

[0262] The above connecting component is positioned between the cam drive unit (441) and the cam member (43) and is connected to the cam drive unit (441) and the cam member (43), allowing the cam member (43) to move.

[0263] The above connecting component may be formed by combining one or more connecting components.

[0264] For example, in the case of a motor, the connecting component may be a plurality of interlocking rotating gears or a ball screw. A rotating shaft member provided in the ball screw may be connected to the rotating shaft of the motor. In addition to this, the connecting component may include a belt or a chain, etc.

[0265] In addition, for example, in the case of a cylinder device, one side of the piston can be connected to the cam member (43).

[0266] The cam drive unit (441) and connecting components can be accommodated inside the housing of the cam moving unit (44). The housing forms the exterior of the cam moving unit (44) and accommodates and protects the cam drive unit (441) and connecting components.

[0267] The cam moving part (44) is connected to the support member (45).

[0268] The support member (45) supports the base member (41), the base guide part (42), the cam member (43), and the cam moving part (44).

[0269] A support guide part (42) (specifically a second member (422)) is connected to one side (e.g., a side) of the support member (45), and a cam moving part (44) is connected to one side and / or the upper surface of the support member (45). The connection is made using a known connection method.

[0270] The support member (45) is placed and fixed to the frame (11).

[0271] The shape of the support member (45) can be formed into a column shape of a preset length, and can also be formed into other shapes.

[0272] The support member (45) can be formed by combining multiple components.

[0273] The riveting device (10) of the present invention may include a control unit (50) (see FIG. 10).

[0274] The control unit (50) is electrically connected to the index member (12), the clamping member (21), the pressure assembly (30), and the support assembly (40).

[0275] The control unit (50) controls the movement of the index member (12).

[0276] The control unit (50) controls the clamping member (21) so that when the index member (12) moves to a preset position, the clamping member (21) grasps the can assembly (15).

[0277] The control unit (50) can control the clamping member (21) so that the center of the rivet assembly (13) placed on the can (14) aligns with the center of the pressing member (31) and the center of the support member (41).

[0278] The control unit (50) can control the movement of the movable member (32) of the pressure assembly (30) so that it moves when the center axis of the pressure member (31), the center axis of the rivet assembly (13), and the center axis of the support member (41) are aligned on the same axis. As the movable member (32) moves, the pressure member (31) connected to the movable member (32) moves.

[0279] The control unit (50) can control the movement distance of the moving member (32).

[0280] The control unit (50) can control the pressure applied by the pressurizing member (31) to the rivet assembly (13). Additionally, the control unit (50) can vary the pressure value applied by the pressurizing member (31) to the rivet assembly (13).

[0281] The control unit (50) can control the cam moving part (44) of the support assembly (40).

[0282] Specifically, the control unit (50) can control the cam drive unit (441) (e.g., a motor device or a cylinder device) of the cam moving unit (44) to control the rotational speed of the motor and the pressure value of the cylinder.

[0283] The control unit (50) can control the movement distance of the support member (41). That is, as the control unit (50) controls the cam moving unit (44), the distance the support member (41) moves can be determined.

[0284] The control unit (50) is composed of various electrical and electronic components. The electrical and electronic components include a printed circuit board, various semiconductor chips, memory, various sensors, wires, etc.

[0285] The control unit (50) controls the overall operation of the riveting device (10) of the present invention by controlling the components examined above.

[0286] The control unit (50) can provide or process appropriate information or functions to the user by processing signals, data, information, etc. that are input or output through the components examined above, or by running an application program stored in memory.
