Description

Battery cell insulation material insertion device and battery cell insulation material insertion method

[0001] This application claims the benefit of priority from Republic of Korea Patent Application No. 10-2024-0029246, dated February 28, 2024, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a device for inserting an insulating member into a battery cell and a method for inserting an insulating member into a battery cell, and more particularly, to a device for inserting an insulating member into a battery cell and a method for inserting an insulating member into a battery cell, in which the insulating member does not move or rotate and does not come off from an arm when inserted into a battery cell.

[0003] Cylindrical battery cells are easy to manufacture and have high energy density per unit weight, so they are used as energy sources in various devices ranging from portable computers to battery-powered cars.

[0004] A cylindrical battery cell is manufactured by housing a jelly-roll-shaped electrode assembly in a cylindrical case, inserting an upper insulating member and a lower insulating member at both ends of the electrode assembly, injecting an electrolyte, and joining a top cap to the top of the cylindrical case.

[0005] In conventional insulating material insertion devices, an upper and lower movable arm moves downward while absorbing the insulating material on its lower surface to insert the insulating material into the battery cell fixed to the lower side of the arm. At this time, an eddy current is generated around the insulating material, which may cause the insulating material to move, rotate, or detach from the arm. As a result, the insulating material may get caught on the carrier that fixes the battery cell or on the upper side of the battery cell, or the battery cell may be damaged by the rotating insulating material, which increases the defect rate of the battery cell and requires the interruption of the manufacturing process.

[0006] Therefore, a method is required to prevent movement, rotation and detachment of the insulating member from the arm when inserting the insulating member.

[0007] A related prior art document is Korean Patent No. 10-0158396.

[0008] The present invention has been devised to solve the above-described problem, and the purpose of the present invention is to provide an insulating member insertion device for a battery cell and a method for inserting an insulating member for a battery cell, in which the insulating member is not moved or rotated when inserted and is not detached from the arm even when the insulating member is absorbed into the arm and inserted into the battery cell.

[0009] The purpose of the present invention is to provide a device for inserting an insulating member into a battery cell and a method for inserting an insulating member into a battery cell, in which an eddy current does not occur or is reduced around the insulating member.

[0010] The purpose of the present invention is to provide an insulating material insertion device for a battery cell and a method for inserting an insulating material for a battery cell, in which an insulating material can be stably absorbed into a cancer and the absorbed state is stably maintained even when an exhaust hole is formed in the cancer.

[0011] The purpose of the present invention is to provide a battery cell insulating member insertion device and a battery cell insulating member insertion method that allow air inside a carrier or battery cell to easily escape to the outside through an exhaust hole.

[0012] The purpose of the present invention is to provide a battery cell insulation member insertion device and a battery cell insulation member insertion method that can easily and inexpensively implement an exhaust hole in a cancer.

[0056] In one embodiment, each of the above adsorption holes (220) may include a first hole portion (222).

[0057] The above first hole (222) can be formed on one end of the first end surface (S1).

[0058] The above first hole (222) can be formed to extend to the first side.

[0059] A plurality of the first holes (222) can be formed spaced apart from each other in the circumferential direction surrounding the main hole (212).

[0060] The above plurality of extension holes (214) can be formed radially around the main hole (212).

[0061] Each of the above extension holes (214) can be formed by penetrating a portion between a pair of the above first holes (222) adjacent to each other along the circumferential direction.

[0062] In one embodiment, when projected onto a virtual plane perpendicular to the extension direction of the arm (200), the plurality of extension holes (214) and the plurality of first holes (222) may be alternately formed in the circumferential direction centered on the main hole (212).

[0063] When projected onto the above virtual surface, the plurality of extension holes (214) and the plurality of first holes (222) can be formed at equal angular intervals in the circumferential direction with the main hole (212) as the center.

[0064] In one embodiment, the cancer (200) may include a body (202) and an adsorption tip (204).

[0065] The above suction tip (204) can be placed on the second side of the main body (202).

[0066] The above first end surface (S1) may be the end surface of the second side of the above suction tip (204).

[0067] The above exhaust hole (210) can be formed by penetrating the above suction tip (204).

[0068] The above exhaust hole (210) can be formed at one end on the first end surface (S1).

[0069] The above exhaust hole (210) may be formed on the outer surface of the suction tip (204).

[0070] To solve the above-described problem, the present invention provides a method (S500) for inserting an insulating member of a battery cell, including an insertion process (S510).

[0071] In the above insertion process (S510), while the insulating member (70) is adsorbed on the first end surface (S1), the arm (200) moves relatively to the second side so that the insulating member (70) can be inserted into the battery cell (50).

[0072] Also, here, when the insulating member (70) is inserted into the battery cell (50), air inside the carrier (100) or the battery cell (50) can be discharged to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200).

[0073] According to embodiments of the present invention, a battery cell insulating member insertion device (10) may include a carrier (100) in which a battery cell (50) having an interior open to a first side is installed in a mounting space open to a first side; and an arm (200) disposed on the first side of the carrier (100) and having an insulating member (70) adsorbed on a first end surface (S1) of a second side opposite to the first side and relatively moved to the second side to insert the insulating member (70) into the battery cell (50). The insulating member (70) may include a through hole (72) formed penetrating the first side and the second side. The arm (200) may include an exhaust hole (210) formed penetrating the arm (200). The above exhaust hole (210) is formed at one end on the first end surface (S1) and is connected to the through hole (72) on the first side and the second side, and the other end is formed on the outer surface of the arm (200), but may be formed on the first side relative to the first end surface (S1).

[0074] Accordingly, when the arm (200) moves relatively to the second side and the insulating member (70) is inserted into the battery cell (50), the air inside the carrier (100) or the battery cell (50) can easily escape to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200), so that an eddy current may not be generated or may be reduced around the insulating member (70). Accordingly, even if the insulating member (70) is absorbed by the arm (200) and inserted into the battery cell (50), the insulating member (70) may not move or rotate during insertion and may not be detached from the arm (200). Accordingly, the defect rate of the battery cell (50) may be reduced and productivity and quality may be improved.

[0075] According to embodiments of the present invention, the exhaust hole (210) and the through hole (72) may face each other.

[0076] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200). Therefore, eddies can be prevented from occurring or reduced around the insulating member (70).

[0077] According to embodiments of the present invention, the arm (200) may include one or more suction holes (220), each of which has one end formed on the first end surface (S1) and extends at least partially toward the first side, forming an air passage for absorbing the insulating member (70), and one or more connection holes (230) that are connected to the other end of the one or more suction holes (220) and are connected to a pressure reducing source. The pressure reducing source may provide negative pressure to the one or more suction holes (220) and the one or more connection holes (230). The exhaust hole (210) may be formed spaced apart from the one or more suction holes (220) and the one or more connection holes (230).

[0078] Accordingly, since the adsorption hole (220) and the connection hole (230) are formed separately from the exhaust hole (210), even if the exhaust hole (210) is formed in the arm (200), the insulating member (70) can be stably adsorbed to the arm (200) and the adsorbed state can be stably maintained.

[0079] According to embodiments of the present invention, the arm (200) may have a side surface (S2) that extends from the edge of the first end surface (S1) to the first side. The exhaust hole (210) may include a main hole (212) and one or more extension holes (214). The main hole (212) may be recessed from the end of the second side of the arm (200) to the first side and may be closed to the first side. Each of the extension holes (214) may have one end that is in communication with the main hole (212) and extends in a direction that at least partially intersects the extension direction of the arm (200), and the other end may be formed on the side surface (S2).

[0080] Accordingly, the path length of the air passing through the exhaust hole (210) can be reduced. For example, the path length of the air passing through the exhaust hole (210) can be shorter than the length of the arm (200). Accordingly, the air inside the carrier (100) or the battery cell (50) can easily escape to the outside through the exhaust hole (210). Accordingly, eddies can be eliminated or reduced around the insulating member (70).

[0081] According to embodiments of the present invention, the exhaust hole (210) may include the main hole (212) and a plurality of extension holes (214). The cross-sectional area of ​​the main hole (212) may be larger than the cross-sectional area of ​​each of the extension holes (214).

[0082] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Therefore, eddies can be prevented or reduced around the insulating member (70).

[0083] According to embodiments of the present invention, the exhaust hole (210) may include the main hole (212) and a plurality of extension holes (214). The plurality of extension holes (214) may be formed radially with the main hole (212) as the center.

[0084] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Therefore, eddies can be prevented or reduced around the insulating member (70).

[0085] According to embodiments of the present invention, when projected onto a virtual plane perpendicular to the extension direction of the arm (200), the plurality of extension holes (214) can be formed at equal angular intervals centered on the main hole (212).

[0086] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Therefore, eddies can be prevented or reduced around the insulating member (70).

[0087] According to embodiments of the present invention, the exhaust hole (210) may include the main hole (212) and a plurality of extension holes (214). The arm (200) may include a plurality of suction holes (220) each having one end formed on the first end surface (S1) and extending at least partially toward the first side to form an air path for suctioning the insulating member (70), and one or more connection holes (230) that are in communication with the other ends of the plurality of suction holes (220) and are connected to a pressure reducing source. The pressure reducing source may provide negative pressure to the plurality of suction holes (220) and the one or more connection holes (230). The main hole (212) and the plurality of extension holes (214) may be formed to be spaced apart from the plurality of suction holes (220) and the one or more connection holes (230).

[0088] Accordingly, even if an exhaust hole (210) is formed in the arm (200), the insulating member (70) can be stably absorbed into the arm (200) and the absorbed state can be stably maintained.

[0089] In addition, since the exhaust hole (210) includes a plurality of extension holes (214), air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Accordingly, eddies can be prevented or reduced around the insulating member (70).

[0090] In addition, since a plurality of adsorption holes (220) are provided, the insulating member (70) can be stably adsorbed to the arm (200) and the adsorbed state can be stably maintained.

[0091] According to embodiments of the present invention, each of the adsorption holes (220) may include a first hole portion (222) formed at one end of the first end surface (S1) and extending toward the first side. A plurality of the first holes (222) may be formed spaced apart from each other in a circumferential direction surrounding the main hole (212). The plurality of extension holes (214) may be formed radially with the main hole (212) as the center. Each of the extension holes (214) may be formed by penetrating a region between a pair of the first holes (222) adjacent to each other along the circumferential direction.

[0092] Accordingly, a plurality of adsorption holes (220) can be formed separately from a plurality of extension holes (214). Accordingly, even if an exhaust hole (210) is formed in the arm (200), the insulating member (70) can be stably adsorbed to the arm (200) and the adsorbed state can be stably maintained.

[0093] According to embodiments of the present invention, when projected onto a virtual plane perpendicular to the extension direction of the arm (200), the plurality of extension holes (214) and the plurality of first holes (222) may be formed alternately in the circumferential direction centered on the main hole (212), but may be formed at equal angular intervals.

[0094] Accordingly, the air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210), while at the same time, the insulating member (70) can be stably absorbed into the arm (200) and the absorbed state can be stably maintained.

[0095] According to embodiments of the present invention, the arm (200) may include a main body (202) and an adsorption tip (204) disposed on the second side of the main body (202). The first end surface (S1) may be an end surface of the second side of the adsorption tip (204). The exhaust hole (210) may be formed by penetrating the adsorption tip (204), and one end may be formed on the first end surface (S1) and the other end may be formed on the outer surface of the adsorption tip (204).

[0096] Accordingly, an exhaust hole (210) can be provided by replacing only the suction tip (204). In other words, the remaining components, excluding the suction tip (204), can be used as conventional components. Accordingly, an exhaust hole (210) can be easily implemented in the arm (200) at low cost.

[0097] In addition, since the exhaust hole (210) is formed at the suction tip (204) at the tip of the arm (200), the length of the exhaust hole (210) can be reduced. Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210).

[0098] According to embodiments of the present invention, the method (S500) for inserting an insulating member of a battery cell may include an insertion process (S510) in which the arm (200) moves relatively toward the second side while the insulating member (70) is adsorbed on the first end surface (S1) to insert the insulating member (70) into the battery cell (50). In the insertion process (S510), when the insulating member (70) is inserted into the battery cell (50), air inside the carrier (100) or the battery cell (50) can be discharged to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200).

[0099] Accordingly, when the arm (200) moves relatively to the second side and the insulating member (70) is inserted into the battery cell (50), the air inside the carrier (100) or the battery cell (50) can easily escape to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200), so that an eddy current may not be generated or may be reduced around the insulating member (70). Accordingly, even if the insulating member (70) is absorbed by the arm (200) and inserted into the battery cell (50), the insulating member (70) may not move or rotate during insertion and may not be detached from the arm (200). Accordingly, the defect rate of the battery cell (50) may be reduced and productivity and quality may be improved.

[0130] The carrier (100) may include a mounting space open to a first side (e.g., an upper side). A battery cell (50) with an interior open to the first side may be mounted in the mounting space.

[0131] Here, the battery cell (50) may include an electrode tab (52) protruding toward the first side.

[0132] The arm (200) may be positioned on the first side relative to the carrier (100). The arm (200) may have an insulating member (70, FIGS. 4 and 5) adsorbed on the first end surface (S1) of the second side (e.g., the lower side) opposite the first side. The arm (200) may move relatively to the second side to insert the insulating member (70) into the battery cell (50).

[0133] Here, the insulating member (70) may have a plate shape. The insulating member (70) may have a ring shape. The insulating member (70) may include a through hole (72) formed penetrating the first side and the second side (Fig. 4, Fig. 5).

[0134] The arm (200) may have a side surface (S2) (Figs. 3 to 5). The side surface (S2) may extend from the edge of the first end surface (S1) to the first side.

[0135] A pressure reducing source may be connected to the arm (200). The pressure reducing source may provide negative pressure to the arm (200) so that the insulating member (70) is absorbed into the first end surface (S1) (Fig. 4).

[0136]

[0137] [cancer]

[0138] The cancer (200) may include a main body (202) and an adsorption tip (204).

[0139] The main body (202) may be formed to extend to a second side (e.g., a lower side). At least a portion of one or more connecting holes (230) described below may be formed in the main body (202).

[0140] The suction tip (204) may be placed on the second side of the main body (202). The first end surface (S1) described above may be the end surface of the second side of the suction tip (204).

[0141] Referring further to FIGS. 3 to 6, the arm (200) may include an exhaust hole (210). Here, the arm (200) may correspond to an adsorption tip (204) of the arm (200). The same applies hereinafter. The arm (200) may include one or more adsorption holes (220). The arm (200) may include one or more connection holes (230).

[0142] The exhaust hole (210) can be formed by penetrating the rock (200).

[0143] The exhaust hole (210) may be formed on one end of the first end surface (S1). The exhaust hole (210) may be connected to the through hole (72) on the first side and the second side. The other end of the exhaust hole (210) may be formed on the outer surface of the arm (200), but may be formed on the first side relative to the first end surface (S1).

[0144] Accordingly, when the arm (200) moves relatively to the second side and the insulating member (70) is inserted into the battery cell (50), the air inside the carrier (100) or the battery cell (50) can easily escape to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200), so that an eddy current may not be generated or may be reduced around the insulating member (70). Accordingly, even if the insulating member (70) is absorbed by the arm (200) and inserted into the battery cell (50), the insulating member (70) may not move or rotate during insertion and may not be detached from the arm (200). Accordingly, the defect rate of the battery cell (50) may be reduced and productivity and quality may be improved.

[0145] If, when inserting the insulating member (70), the insulating member (70) moves or rotates or is detached from the arm (200), the insulating member (70) may get caught on the top of the carrier (100) or the battery cell (50), or the electrode tab (52) of the battery cell (50) may be damaged. As a result, the defect rate of the battery cell (50) may increase and the manufacturing process may have to be stopped.

[0146] The exhaust hole (210) and the through hole (72) may face each other.

[0147] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200). Therefore, eddies can be prevented from occurring or reduced around the insulating member (70).

[0148] The other end of the exhaust hole (210) may not be inserted into the carrier (100) or the battery cell (50).

[0149] The exhaust hole (210) can be formed apart from one or more suction holes (220) and one or more connection holes (230) described later.

[0150] Accordingly, since the adsorption hole (220) and the connection hole (230) are formed separately from the exhaust hole (210), even if the exhaust hole (210) is formed in the arm (200), the insulating member (70) can be stably adsorbed to the arm (200) and the adsorbed state can be stably maintained.

[0151] The exhaust hole (210) may be formed by penetrating the suction tip (204). One end of the exhaust hole (210) may be formed on the first end surface (S1). The other end of the exhaust hole (210) may be formed on the outer surface of the suction tip (204) (Figs. 3 to 6).

[0152] Accordingly, an exhaust hole (210) can be provided by replacing only the suction tip (204). In other words, the remaining components, excluding the suction tip (204), can be used as conventional components. Accordingly, an exhaust hole (210) can be easily implemented in the arm (200) at low cost.

[0153] In addition, since the exhaust hole (210) is formed at the suction tip (204) at the tip of the arm (200), the length of the exhaust hole (210) can be reduced. Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210).

[0154] The exhaust hole (210) may include a main hole (212) and one or more extension holes (214). The exhaust hole (210) may include a plurality of the extension holes (214).

[0155] The main hole (212) can be formed by recessing from the end of the second side of the arm (200) to the first side. The main hole (212) can be closed on the first side. That is, one end of the main hole (212) can be formed on the first end surface (S1) and the other end can be closed. An electrode tab (52) can be inserted into the main hole (212) (Fig. 2).

[0156] Each extension hole (214) may have one end connected to the main hole (212). Each extension hole (214) may be formed to extend in a direction that at least partially intersects the extension direction of the arm (200). The other end of each extension hole (214) may be formed on the side surface (S2) of the arm (200).

[0157] Accordingly, the path length of the air passing through the exhaust hole (210) can be reduced. For example, the path length of the air passing through the exhaust hole (210) can be shorter than the length of the arm (200). Accordingly, the air inside the carrier (100) or the battery cell (50) can easily escape to the outside through the exhaust hole (210). Accordingly, eddies can be eliminated or reduced around the insulating member (70).

[0158] The cross-sectional area of ​​the main hole (212) may be larger than the cross-sectional area of ​​each extension hole (214).

[0159] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Therefore, eddies can be prevented or reduced around the insulating member (70).

[0160] A plurality of extension holes (214) can be formed radially around the main hole (212).

[0161] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Therefore, eddies can be prevented or reduced around the insulating member (70).

[0162] When projected onto a virtual plane perpendicular to the extension direction of the cancer (200), a plurality of extension holes (214) can be formed at equal angular intervals centered on the main hole (212) (Fig. 6).

[0163] Accordingly, air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Therefore, eddies can be prevented or reduced around the insulating member (70).

[0164] The main hole (212) and the plurality of extension holes (214) can be formed spaced apart from the plurality of suction holes (220) and one or more connection holes (230) described later.

[0165] Accordingly, even if an exhaust hole (210) is formed in the arm (200), the insulating member (70) can be stably absorbed into the arm (200) and the absorbed state can be stably maintained.

[0166] In addition, since the exhaust hole (210) includes a plurality of extension holes (214), air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210). Accordingly, eddies can be prevented or reduced around the insulating member (70).

[0167] In addition, since a plurality of adsorption holes (220) are provided, the insulating member (70) can be stably adsorbed to the arm (200) and the adsorbed state can be stably maintained.

[0168] As described above, a plurality of extension holes (214) may be formed radially around the main hole (212). At this time, each extension hole (214) may be formed by penetrating a region between a pair of first hole portions (222) described later, which are adjacent to each other in the circumferential direction surrounding the main hole (212).

[0169] Accordingly, a plurality of adsorption holes (220) can be formed separately from a plurality of extension holes (214). Accordingly, even if an exhaust hole (210) is formed in the arm (200), the insulating member (70) can be stably adsorbed to the arm (200) and the adsorbed state can be stably maintained.

[0170] When projected onto a virtual plane perpendicular to the extension direction of the arm (200), a plurality of extension holes (214) and a plurality of first holes (222) may be formed alternately in the circumferential direction of the main hole (212) with the main hole (212) as the center, but may be formed at equal angular intervals.

[0171] Accordingly, the air inside the carrier (100) or battery cell (50) can easily escape to the outside through the exhaust hole (210), while at the same time, the insulating member (70) can be stably absorbed into the arm (200) and the absorbed state can be stably maintained.

[0172]

[0173] Each of one or more or multiple adsorption holes (220) may be formed on the first end surface (S1) of the arm (200). Each of one or more or multiple adsorption holes (220) may be formed to extend at least partially toward the first side. Each of one or more or multiple adsorption holes (220) may form an air path for adsorbing the insulating member (70).

[0174] Each adsorption hole (220) may include a first hole portion (222). Each adsorption hole (220) may include a second hole portion (224). One end of the first hole portion (222) may be formed on the first end surface (S1). The first hole portion (222) may be formed to extend toward the first side.

[0175] A plurality of first holes (222) can be formed spaced apart from each other in the circumferential direction surrounding the main hole (212).

[0176] The second hole (224) may be connected at one end with the other end of the first hole (222). The second hole (224) may be connected at the other end with the connecting hole (230). The second hole (224) may be formed to extend in a direction that intersects at least partially with the extension direction of the arm (200).

[0177] One or more connecting holes (230) may be formed in the main body (202) and / or the suction tip (204). One or more connecting holes (230) may be connected to the other end of one or more or a plurality of suction holes (220). One or more connecting holes (230) may be connected to a pressure reducing source.

[0178] A pressure reducing source can provide negative pressure to one or more or a plurality of adsorption holes (220) and one or more connection holes (230).

[0179]

[0180] [Method of inserting insulation material into a battery cell]

[0181] Referring to FIG. 7, a method (S500) for inserting an insulating member of a battery cell according to one embodiment of the present invention may include an insertion process (S510).

[0182] In the insertion process (S510), while the insulating member (70) is adsorbed on the first end surface (S1), the arm (200) moves relatively to the second side so that the insulating member (70) can be inserted into the battery cell (50).

[0183] Here, when the insulating member (70) is inserted into the battery cell (50), the air inside the carrier (100) or the battery cell (50) can be discharged to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200).

[0184] Accordingly, when the arm (200) moves relatively to the second side and the insulating member (70) is inserted into the battery cell (50), the air inside the carrier (100) or the battery cell (50) can easily escape to the outside through the through hole (72) of the insulating member (70) and the exhaust hole (210) of the arm (200), so that an eddy current may not be generated or may be reduced around the insulating member (70). Accordingly, even if the insulating member (70) is absorbed by the arm (200) and inserted into the battery cell (50), the insulating member (70) may not move or rotate during insertion and may not be detached from the arm (200). Accordingly, the defect rate of the battery cell (50) may be reduced and productivity and quality may be improved.
