Description

Tape reel feeder and insulation tape feed method, battery pack and automobile

[0001] The present invention relates to a tape reel supply device and a method for supplying insulating tape, a battery pack manufactured thereby, and an automobile including the same. More specifically, the invention relates to a tape reel supply device and a method for supplying insulating tape that replaces and supplies a tape reel cassette unit wound with insulating tape, a battery pack manufactured thereby, and an automobile including the same.

[0002] Unlike primary batteries, which cannot be recharged, secondary batteries refer to batteries capable of charging and discharging, and are applied not only to portable devices but also to electric vehicles (EVs) and hybrid electric vehicles (HEVs) powered by electric driving sources.

[0003] Currently, widely used types of secondary batteries include lithium-ion batteries, lithium-polymer batteries, nickel-cadmium batteries, nickel-hydrogen batteries, and nickel-zinc batteries. The operating voltage of these unit secondary battery cells, or unit battery cells, is approximately 2.5V to 4.6V. Therefore, if a higher output voltage is required, a battery pack is formed by connecting multiple battery cells in series. Additionally, a battery pack is formed by connecting multiple battery cells in parallel depending on the charge / discharge capacity required for the battery pack. Accordingly, the number of battery cells included in the battery pack can be varied depending on the required output voltage or charge / discharge capacity.

[0004] When configuring a battery pack by connecting multiple battery cells in series or parallel, it is common practice to first configure a battery module consisting of at least one battery cell, preferably multiple battery cells, and then use at least one such battery module to configure the battery pack by adding other components. Here, a battery module refers to a component in which multiple battery cells are connected in series or parallel, and a battery pack refers to a component in which multiple battery modules are connected in series or parallel to increase capacity and output.

[0005] Battery cells that make up a battery module are classified into pouch type, cylindrical type, prismatic type, etc., depending on the shape of the battery case.

[0006] Among these, cylindrical cells offer excellent safety as they primarily utilize a metal case with a cylindrical structure. They also have the advantage of high energy density by housing a jelly-roll type electrode assembly inside the case, and make it easy to configure a large-capacity power storage device by connecting multiple cells in series or parallel.

[0007] The electrode assembly, housed in a cylindrical case, is a rechargeable power generation device composed of a stacked structure of an anode, a separator, and a cathode, and is classified into jellyroll, stack, and stack / folding types. The jellyroll type is formed by winding a separator between long sheet-shaped anodes and cathodes coated with active material; the stack type is formed by sequentially stacking multiple anodes and cathodes of a predetermined size with a separator in between; and the stack / folding type is a composite structure of the jellyroll and stack types. Among these, the jellyroll electrode assembly has the advantages of being easy to manufacture and having a high energy density per unit weight.

[0008] An insulating tape for the positive terminal is attached to the side of a jellyroll-type electrode assembly with a welded positive current collector plate. During this process, time is required to load a new insulating tape after the use of the wound insulating tape is completed. Specifically, the process may be interrupted due to the replacement of the new insulating tape and its loading.

[0009] The present invention aims to easily supply insulating tape by replacing a tape reel cassette unit on which insulating tape is wound.

[0037] A tape reel supply device (101) for supplying insulating tape according to one embodiment of the present invention is positioned in a process of attaching and forming an insulating tape for the positive terminal portion on the side of a jelly roll-type electrode assembly. The cylindrical cathode insulator taping (CIP) process may include a process of attaching and forming an insulating tape for the positive terminal portion on the side of a jelly roll on which a positive integrated plate is welded.

[0038] The tape reel supply device (101) supplies tape materials to the CIP facility.

[0039] As illustrated in FIGS. 1 to 3, a tape reel supply device (101) according to an embodiment of the present invention includes a supply unit (200).

[0040] The conveying unit (100) conveys the insulating tape. The conveying unit (100) includes a plurality of rollers.

[0041] The supply unit (200) can supply an insulating tape wound on a tape reel cassette unit (220) to the transfer unit (100). A tape reel cassette unit (220) on which an insulating tape is wound may be placed in the supply unit (200). The supply unit (200) can supply the insulating tape wound on the tape reel cassette unit (220) to the transfer unit (100). The supply unit (200) can replace the tape reel cassette unit (220) so that a new insulating tape is supplied to the transfer unit (100).

[0042] As illustrated in FIGS. 1 and 2, the supply unit (200) may include a supply body (210). The supply body (210) may be formed in an annular shape. Additionally, a plurality of tape reel cassette units (220) on which insulating tape is wound may be spaced apart in the supply body (210). Furthermore, the supply body (210) may include a plurality of tape reel cassette units (220) to replace and supply insulating tape to the transfer unit (100). The tape reel cassette units (220) may include first, second, third, and fourth tape reel cassette units (221, 222, 223, 224).

[0043] Additionally, when the use of one of the plurality of tape reel cassette units (220) is completed, the supply body (210) can be rotated so that the insulating tape wound on the remaining tape reel cassette unit (220) is supplied toward the transfer unit (100). Specifically, the supply body (210) can be rotated by a rotary driving member (281) when replacing the tape reel cassette unit (220).

[0044] In addition, a tape reel supply device (101) according to one embodiment of the present invention may further include a splicing part (300).

[0045] The splicing unit (300) can combine the insulating tape supplied from the supply unit (200) with the insulating tape of the transfer unit (100). Additionally, the splicing unit (300) can organize and combine the new insulating tape wound on the replaced tape reel cassette unit (220) supplied from the supply unit (200) with the insulating tape already supplied to the transfer unit (100). That is, the splicing unit (300) can join a portion of the insulating tape already supplied with a portion of the insulating tape supplied as a replacement.

[0046] The splicing unit (300) of the tape reel supply device (101) supplying an insulating tape according to one embodiment of the present invention may include a tape cutting unit (310) and a tape attachment unit (320), as shown in FIG. 2.

[0047] The tape cutting unit (310) can cut one end of the insulating tape supplied to the conveying unit (100). Specifically, the tape cutting unit (310) can cut the insulating tape between the conveying unit (100) and the tape reel cassette unit (220) to organize the insulating tape from the tape reel cassette unit (220) after use.

[0048] The tape attachment unit (320) can connect one side of the insulating tape with one side of the insulating tape supplied from the replaced tape reel cassette unit (220). Additionally, the tape attachment unit (320) can connect one side of the insulating tape supplied from the replaced tape reel cassette unit (220) with one side of the insulating tape that is cut and trimmed at one end and is relatively adjacent to the transport unit (100) than the tape reel cassette unit (220). Specifically, the tape attachment unit (320) can cause one side of the previously supplied insulating tape and one side of the replaced insulating tape to overlap and be joined together.

[0049] In addition, the splicing part (300) of the tape reel supply device (101) supplying an insulating tape according to one embodiment of the present invention may further include a vacuum block (330) as shown in FIG. 2.

[0050] The vacuum block (330) can be positioned to come into contact with the insulating tape. One side of the vacuum block (330) can be positioned to face one side of the insulating tape supplied to the transfer unit (100). The vacuum block (330) can be used to clamp or adsorb the insulating tape to move it.

[0051] Specifically, a vacuum can be formed inside the vacuum block (330) according to the flow of fluid for adsorbing the insulating tape.

[0052] In addition, the tape attachment unit (320) of the tape reel supply device (101) supplying an insulating tape according to one embodiment of the present invention may include a first attachment cylinder (322) and a second attachment cylinder (321), as shown in FIG. 2.

[0053] The first attachment cylinder (322) can move the insulating tape in a direction that moves it closer to the vacuum block (330). Specifically, the first attachment cylinder (322) is spaced apart from the bottom of the vacuum block (330) so that it can move the insulating tape to be adsorbed to the vacuum block (330) as it moves up and down.

[0054] The first attachment cylinder (322) can provide force to move the insulating tape toward the vacuum block (330).

[0055] The second attachment cylinder (321) can enable the vacuum block (330) to vacuum adsorb. Specifically, the second attachment cylinder (321) can enable the vacuum block (330) to vacuum adsorb an insulating tape. Additionally, the second attachment cylinder (321) can control the lifting and lowering of the vacuum block (330).

[0056] Alternatively, a vacuum pump that provides suction force into the vacuum block (330) may be separately provided and controlled.

[0057] In addition, the tape reel cassette unit (220) of the tape reel supply device (101) supplying insulating tape according to one embodiment of the present invention may include a main roll (230), a first sliding roll (240), and a second sliding roll (250), as shown in FIG. 3.

[0058] Insulating tape (10) is wound on the main roll (230). Specifically, the main roll (230) can be supported on a cassette body (270).

[0059] The first sliding roll (240) can move the insulating tape wound on the main roll (230) toward the conveying unit (100). The outer surface of the first sliding roll (240) may face the surface on which the adhesive portion of the insulating tape is formed. Additionally, the first sliding roll (240) is spaced apart from the main roll (230) on the cassette body (270), and the center of rotation of the first sliding roll (240) may be positioned relatively higher than the center of the main roll (230).

[0060] The second sliding roll (250) may be positioned between the main roll (230) and the first sliding roll (240). Additionally, the second sliding roll (250) may guide the movement of the insulating tape. Specifically, the outer surface of the second sliding roll (250) may face the surface where the non-adhesive portion of the insulating tape is formed. Furthermore, the rotation center of the second sliding roll (250) may be positioned between the rotation center of the first sliding roll (240) and the rotation center of the main roll (230).

[0061] That is, the outer surfaces of the first sliding roll (240) and the second sliding roll (250) can each be positioned to face different outer surfaces of the insulating tape.

[0062] For example, multiple first sliding rolls (240) may be spaced apart based on the center of rotation. Additionally, multiple second sliding rolls (250) may be spaced apart based on the center of rotation. Additionally, multiple main rolls (230) may be spaced apart based on the center of rotation.

[0063] In addition, the tape reel cassette unit (220) of the tape reel supply device (101) supplying an insulating tape according to one embodiment of the present invention may further include a guide (260).

[0064] The guide (260) can guide the movement of the insulating tape passing through the first sliding roll (240). The guide (260) can guide the movement of the insulating tape being drawn out from the tape reel cassette unit (220).

[0065] Additionally, the guide (260) may be supported on the cassette body (270). Specifically, the tape reel cassette unit (220) may have the guide (260) extended toward the outer circumference of the supply body (210). One side of the guide (260) may be positioned protruding from the outer circumference of the supply body (210) to guide the insulating tape toward the transfer unit (100).

[0066] Additionally, an opening (261) may be formed in the guide (260). An opening (261) may be formed in the guide (260) such that a portion is opened in a direction parallel to the longitudinal direction of the insulating tape.

[0067] At least a portion of the first attachment cylinder (322) is inserted into the opening (261) to help the insulating tape (10) move and be adsorbed toward the vacuum block (330) by the force provided by the first attachment cylinder (322). That is, the insulating tape (10) can be moved and pressed toward the vacuum block (330) by the pressure of the first attachment cylinder (322) that has moved toward the opening (261).

[0068] In addition, the cutting unit (310) of the tape reel supply device supplying insulating tape according to one embodiment of the present invention may further include a cutter (312) and a cutting cylinder (311).

[0069] The cutter (312) may be capable of cutting the insulating tape. For example, the cutter (312) may be a blade capable of cutting the insulating tape upon contact with the insulating tape. Specifically, the cutter (312) moves along a part of the vacuum block (330) or along its side and may cut the insulating tape upon contact with it.

[0070] The cutting cylinder (311) can raise and lower the cutter (312). The cutting cylinder (311) is supported by the body of the splicing part (300) so that the cutter (312) can be lowered to cut the insulating tape.

[0071] In addition, a tape reel supply device (101) supplying an insulating tape according to one embodiment of the present invention may further include a stopper (700).

[0072] The stopper (700) can stop the operation of the transfer unit (100). Specifically, the stopper (700) can restrict the rotation of the roller of the transfer unit (100). The stopper (700) can stop the operation of the transfer unit (100) and restrict the movement of the insulating tape according to the operation of the transfer unit (100).

[0073] The stopper (700) is operated when the tape reel cassette unit (220) is replaced, and can restrict the movement of the insulating tape.

[0074] In addition, a tape reel supply device (101) for supplying an insulating tape according to one embodiment of the present invention may further include a control unit (600), a detection member (500), a rotary driving member (281), and an inlet / outlet driving member (291), as illustrated in FIG. 11.

[0075] The detection member (500) can detect the condition of the insulating tape of the tape reel cassette unit (220) and transmit information to the control unit (600). Additionally, based on the information from the detection member (500), the control unit (600) can determine whether the tape reel cassette unit (220) needs to be replaced.

[0076] The rotary drive member (281) is controlled by the control unit (600) and can rotate the supply body (210) of the supply unit (200). The rotary drive member (281) can perform replacement of a plurality of tape reel cassette units (220).

[0077] The pull-out drive member (291) can move the tape reel cassette unit (220) or the supply body (210) back and forth so that a part of the tape reel cassette unit (220) is inserted and positioned between the first attachment cylinder (322) and the vacuum block (330).

[0078] The control unit (600) can control the rotary drive member (281), the pull-out drive member (291), the first attachment cylinder (322), the second attachment cylinder (321), the cutting cylinder (311), and the stopper (700).

[0079] Accordingly, a tape reel supply device (101) for supplying insulating tape according to one embodiment of the present invention can supply insulating tape by replacing a tape reel cassette unit (220) that has been used among a plurality of tape reel cassette units (220) each having insulating tape wound thereon with a new tape reel cassette unit (220).

[0080] Specifically, the tape reel supply device (101) can replace the tape reel cassette unit (220) through rotation, thereby facilitating the replacement of the tape reel cassette unit (220). That is, the tape reel cassette unit (220) can be easily replaced by the turret-type supply unit (200). In other words, the time for replacing the tape reel cassette unit (220) and supplying the replaced insulating tape can be shortened.

[0081] Additionally, the tape reel supply device (101) can combine the replaced insulating tape supplied to the tape reel supply device (101) with the previously supplied insulating tape so that they can be stably supplied through the transfer unit (100).

[0082] Hereinafter, with reference to FIGS. 1 to 11, a method for supplying an insulating tape to the side of a jelly roll on which an anode integrated plate is welded is described in detail. The method for supplying the insulating tape includes the following steps.

[0083] The control unit (600) can determine whether to replace the tape reel cassette unit (220) based on information received from a detection member (500) that detects the state of the tape reel cassette unit (220).

[0084] When the control unit (600) determines that the insulation tape needs to be replaced based on the information received from the detection member (500), it operates the stopper (700) and clamps and cuts the insulation tape (10) currently supplied from the first tape reel cassette unit (220).

[0085] As illustrated in FIG. 4, the control unit (600) causes the vacuum block (330) and the cutter (312) to descend. Specifically, the second attachment cylinder (321) is operated so that the insulating tape is clamped between the guide (260) and the vacuum block (330). Additionally, the control unit (600) can operate the cutting cylinder (311) so that the insulating tape between the vacuum block (330) and the supply unit (200) is cut by the cutter (312).

[0086] As illustrated in FIG. 5, a clamped insulating tape is adsorbed. Specifically, the clamped insulating tape (10) can be adsorbed by the pressure applied by the vacuum block (330). Additionally, the first attachment cylinder (322) can be extended and penetrate the opening (261) to apply pressure so that the insulating tape (10) is adsorbed to one side of the vacuum block (330). At this time, the vacuum block (330) can be cushioned by the buffer member (340).

[0087] As illustrated in FIG. 6, the vacuum block (330) and cutter (312) on which the clamped insulating tape (10) is adsorbed are moved back in an upward direction. At this time, the vacuum block (330) can suck up the non-adhesive side of the insulating tape (10).

[0088] In addition, the first attachment cylinder (322) can be moved in a contracting direction.

[0089] While the cutter (312) is moving in an upward direction, the supply body (210) of the supply unit (200) is rotated to wait for the second tape reel cassette unit (222) to be supplied toward the supply unit (200). Specifically, the supply body (210) is rotated so that a portion of the tape reel cassette unit (220) for replacement can be fed into the splicing unit (300). Specifically, a pull-out drive member (291) capable of advancing and retracting toward the transfer unit (100) can be operated on the tape reel cassette unit (220).

[0090] As illustrated in FIG. 7, the first sliding roll (240) of the second tape reel cassette unit (222) is operated so that a portion of the insulating tape (20) is supplied toward the transfer unit (100) through the upper part of the guide (260). Specifically, a portion of the newly supplied insulating tape (10) can be overlapped with the lower part of the previously supplied insulating tape (10). That is, the adsorption surface of the insulating tape (10) adsorbed to the vacuum block (330) and the non-adsorption surface of the insulating tape (10) supplied in replacement can be spaced apart to face each other.

[0091] As shown in FIG. 8, the vacuum block (330) is moved in a direction adjacent to the insulating tape supplied from the second tape reel cassette unit (222).

[0092] By operating the second attachment cylinder (321), the vacuum block (330) can be directed to be adjacent to the guide (260).

[0093] As illustrated in FIG. 9, the clamped insulating tape (10) and the insulating tape (20) supplied from the second tape reel cassette unit (222) can be combined. At least a portion of the first attachment cylinder (322) can be moved in a direction where it is inserted into the opening (261) of the guide (260). At this time, the adsorption surface of the insulating tape (10) adsorbed to the vacuum block (330) and the non-adsorption surface of the supplied insulating tape (20) can be bonded to each other. At this time, the suction force provided to the vacuum block (330) can be released. Additionally, the stopper (700) can be released to form a state where the transfer unit (100) can be operated.

[0094] As illustrated in FIG. 10, the second tape reel cassette unit (222) allows the insulating tape (20) to be continuously supplied to the transfer unit (100). The second attachment cylinder (321) raises the vacuum block (330). As the roller of the transfer unit (100) rotates, the insulating tape (10) between the guide (260) and the vacuum block (330) can be moved. That is, the previously supplied insulating tape (10) and the replacement supplied insulating tape (20) can be combined and connected so that the insulating tape is supplied to the transfer unit (100).

[0095] Therefore, the tape reel supply method can effectively supply a new insulating tape without equipment floating during the CIP process when replacing the tape reel cassette unit (220).

[0096] A jelly roll-type electrode assembly manufactured by the tape reel supply device (101) described above can be received in a battery can to manufacture a cylindrical battery cell. Additionally, a plurality of cylindrical battery cells can be received in a pack case to form a battery pack (1000).

[0097] In addition, according to one embodiment of the present invention, the vehicle (1) may include the battery pack (1000) described above. FIG. 12 is a drawing illustrating an electric vehicle (1) equipped with a battery pack (2000). In the electric vehicle (1), the wheels are driven by a motor that receives power from the battery pack (2000), and the electric vehicle can be operated.

[0098] Although the present invention has been described with reference to preferred embodiments as described above, it is not limited to the aforementioned embodiments, and various changes and modifications may be made by those skilled in the art within the scope of the invention without departing from the spirit of the invention.
