Description

Technology Field

[0001] The present invention relates to an automatic packaging device and a packaging method, and more specifically, to an automatic packaging device and a packaging method for a secondary battery module that automatically inserts an interleaving sheet so that the secondary battery module can be placed in the correct position of a paper box. Background Technology

[0003] Unlike primary batteries, which cannot be recharged, secondary batteries are batteries that can be charged and discharged.

[0004] Low-capacity rechargeable batteries are used in small portable electronic devices such as smartphones, feature phones, laptop computers, digital cameras, and camcorders, while high-capacity rechargeable batteries are widely used as power sources for motor drives and power storage batteries for hybrid and electric vehicles.

[0005] Secondary batteries are manufactured in various shapes; for example, in the case of prismatic or pouch-type batteries, trays are commonly used as packaging materials for transport and storage.

[0006] Furthermore, the secondary batteries are laminated onto interlayer paper using secondary battery packaging equipment and packaged in a semi-finished or finished product state for transportation.

[0007] The interlayer is utilized by placing the secondary battery and then laminating the interlayer on top of it.

[0008] And, the stacked interleaf sheets are again accommodated in a separate box or container.

[0009] Since the interlayer used in this stacked manner also serves to protect the secondary battery, if there is a problem with the stacked structure, the secondary battery may be damaged.

[0010] For example, if the casing cannot withstand the weight of the secondary batteries or external shocks, the batteries may collide with each other or short-circuit electrically, leading to serious problems.

[0011] Even if it does not reach that level, if the overall height of the stack is reduced, such as when the stacked interlayers inside the box are crushed, the interlayers inside the box separate and move from each other, so the possibility of the secondary battery being damaged due to collisions with each other increases.

[0012] Meanwhile, conventionally, the sheets were manually fed into the secondary battery packaging equipment.

[0013] As a result, when stacking sheets and secondary batteries in multiple layers, if the support between the sheets is not uniform, a height difference may occur, causing a height difference at the top of the stacked sheets, or a short circuit may occur due to leakage or flow of the secondary battery caused by the empty space between the stacked sheets and the box.

[0014] Therefore, there is a problem where production loss occurs due to uncertainty regarding the correct positioning in the box during the packaging process of secondary batteries.

[0015] The information described above disclosed in the background technology of this invention is intended only to enhance understanding of the background of the present invention and may therefore include information that does not constitute prior art. The problem to be solved

[0063] FIG. 1 is a perspective view showing an automatic packaging device for secondary batteries according to an embodiment of the present invention.

[0064] Referring to FIG. 1, an automatic secondary battery packaging device according to one embodiment of the present invention includes a first conveyor (100), a paper transfer unit (200), a stacking unit (300), a multi-joint robot (400), and a fourth conveyor (500).

[0065] The first conveyor (100) transports a pallet (P) (PALETTE) on which a lower box (B) is placed.

[0066] Specifically, the first conveyor (100) transports the pallet (P) with the lower box (B) stacked in the direction (C) of the stacking section (300).

[0067] The lower box (B) is on which the secondary battery (800) module is placed, and preferably can be made of paper material.

[0068] The interlayer transfer unit (200) transfers an interlayer (600; TRAY) in which multiple layers are stacked.

[0069] Meanwhile, the upper portion (600) has one or more grooves (601) formed therein for mounting multiple secondary batteries (800).

[0070] And, the area of ​​the above-mentioned groove (601) is made to be the same size as the area of ​​the secondary battery (800) that is placed on the upper part of the interleaf (600).

[0071] In addition, the partition (600) has a plurality of partitions (602) formed at the bottom.

[0072] The partition (602) separates the multiple secondary batteries (800) placed at the bottom of the inter-cell (600) from one another.

[0073] As a result, when multiple secondary batteries (800) are placed on the upper part of the sheet (600), the secondary batteries (800) can be placed in the correct position without being disturbed, and can effectively prevent shaking during movement.

[0074] In the stacking section (300), a secondary battery (800) placed in the waiting section of the lower box (B) transported from the first conveyor (100) and the uppermost sheet (600) among the plurality of sheets (600) transported from the sheet transport section (200) are stacked alternately to form a stacked member (700).

[0075] The multi-joint robot (400) alternately stacks the secondary battery (800) and the uppermost of the plurality of interlayer sheets (600) on the lower box (B) placed on the pallet (P).

[0076] The fourth conveyor (500) transports a stacked member (700) from the stacking section (300), and receives the stacked member (700) from the third conveyor (310) of the stacking section (300) in the stacking area (A) and transports it to a pre-set area.

[0078] Hereinafter, an inter-sheet transfer unit according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0079] FIG. 2 is a perspective view showing an interleaf transfer unit of an automatic secondary battery packaging device according to an embodiment of the present invention, FIG. 3 is a plan view showing a plan of an interleaf transfer unit according to an embodiment of the present invention, and FIG. 4 is a side view showing a side of an interleaf transfer unit according to an embodiment of the present invention.

[0080] Referring to FIGS. 2 to 4, a paper transfer unit (200) according to one embodiment of the present invention includes a second conveyor (210), a guide unit (220), and a stopper (230).

[0081] The second conveyor (210) transports multiple stacked sheets (600).

[0082] Specifically, the second conveyor (210) manually feeds multiple sheets (600) and transports the stacked sheets (600) in the direction (C) of the stacking section (300).

[0083] The guide section (220) is positioned on the side of the second conveyor (210) as shown in FIG. 3 and guides the transport of the inter-sheet (600) that is transported along the second conveyor (210).

[0084] And, the guide section (220) can be varied according to the width of the inter-sheet (600) being transported along the second conveyor (210).

[0085] As a result, the guide section (220) can accommodate various widths of the interlayer (600) being transported along the second conveyor (210).

[0086] This guide section (220) includes a straight section (221), an inclined section (222), and a hydraulic cylinder (223).

[0087] The straight section (221) extends along the second conveyor (210).

[0088] The inclined section (222) slopes outward from the end of the direction in which the paper (600) flows from the straight section (221).

[0089] As a result, when the paper (600) enters the second conveyor (210), the inclined section (222) can be aligned by moving along the inclined section (222) even if the user carelessly places the paper (600) on the second conveyor (210).

[0090] The hydraulic cylinder (223) is coupled to the opposite side of the straight section (221) in the direction where the second conveyor (210) is positioned, and the straight section (221) is varied according to the width of the inter-sheet (600).

[0091] This allows the hydraulic cylinder (223) to use various sizes of interleaf paper (600).

[0092] The stopper (230) is positioned at the end of the direction in which the interleaf (600) is transported on the second conveyor (210) as shown in FIG. 4, and the front of the interleaf (600) transported along the second conveyor (210) comes into contact with it to restrict the transport of the interleaf (600).

[0093] And, the stopper (230) can easily align the front of the sheet (600) by contacting the front of the sheet (600) in the direction in which the sheet (600) is transported.

[0095] Hereinafter, a laminated portion according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0096] FIG. 5 is a perspective view showing a stacking section of an automatic secondary battery packaging device according to an embodiment of the present invention, FIG. 6 is a side view showing a side of a stacking section according to an embodiment of the present invention, and FIG. 7 to 10 are perspective views showing a stacked state of a stacked member according to a sensing section according to an embodiment of the present invention.

[0097] Referring to FIGS. 5 and 6 and FIGS. 7 through 10, a stacking unit (300) according to an embodiment of the present invention includes a third conveyor (310) and a sensing unit (320).

[0098] The third conveyor (310) is positioned in a direction orthogonal to the first conveyor (100) and the second conveyor (210) as shown in FIG. 1, and receives a pallet (P) on which a lower box (B) is placed from the first conveyor (100).

[0099] The sensing unit (320) is positioned in the stacking area (A) where the stacking member (700) is formed on the third conveyor (310) and detects the stacking member (700) being transported by the third conveyor (310).

[0100] This sensing unit (320) includes a support (321), a first sensor (322), a second sensor (323), a third sensor (324), and a fourth sensor (325).

[0101] Meanwhile, the stacked member (700) is formed by stacking a secondary battery (800) and an interlayer (600) alternately as shown in FIG. 6, and is composed of a first stacked member (701), a second stacked member (702), and a third stacked member (703).

[0102] The first stacked member (701) is formed by stacking a secondary battery (800) and a paper sheet (600) in order on a lower box (B) placed on a pallet (P), the second stacked member (702) is formed by stacking a secondary battery (800) and a paper sheet (600) in order on top of the first stacked member (701), and the third stacked member (703) is formed by stacking a secondary battery (800) and a paper sheet (600) in order on top of the second stacked member (702).

[0103] The support member (321) is positioned in an area that does not overlap with the stacked member (700) in the stacking area (A), and is longer than the height of the stacked member (700).

[0104] Specifically, it is preferable that the support members (321) are formed in pairs and are each placed in the corner areas of the pallet (P) transported via the third conveyor (310) in the stacking area (A) where the stacking member (700) is formed.

[0105] The first sensor (322) is fixed at a height that can detect the lower box (B) stacked on the pallet (P) on the support (321) as shown in FIG. 7.

[0106] Then, when the first sensor (322) detects the lower box (B) placed on the pallet (P) in the stacking area (A), the transport of the third conveyor (310) stops and the first stacking member (701) is stacked on the lower box (B).

[0107] The second sensor (323) is fixed at a height where it can detect the first stacked member (701) on the support (321) as shown in FIG. 8, that is, at a higher position than the first sensor (322).

[0108] Then, when the second sensor (323) detects the first stacked member (701) stacked on the lower box (B), the second stacked member (702) is stacked on top of the first stacked member (701).

[0109] The third sensor (324) is fixed at a height where it can detect the second stacked member (702) on the support (321) as shown in FIG. 9, that is, at a position higher than the second sensor (323).

[0110] And, when the third sensor (324) detects the second stacked member (702) stacked on the first stacked member (701), the third stacked member (703) is stacked on top of the second stacked member (702).

[0111] The fourth sensor (325) is fixed at a height where it can detect the third stacked member (703) on the support (321) as shown in FIG. 10, i.e., at a higher position than the third sensor (324).

[0112] Then, when the fourth sensor (325) detects the third stacked member (703) stacked on the second stacked member (702), the third conveyor (310) transports the pallet (P) on which the stacked member (700) is stacked to the position where the fourth conveyor (500) is placed.

[0113] Meanwhile, although the laminated member (700) of the present invention has been described as being composed of a first laminated member (701) to a third laminated member (703), it may be composed of more than the third laminated member (703) and less than the second laminated member (702) depending on the usage environment.

[0114] Accordingly, the number of sensors can also be changed in the same way depending on the number of stacked members (700).

[0116] Hereinafter, a multi-joint robot according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0117] FIG. 11 is a perspective view showing a multi-joint robot of an automatic secondary battery packaging device according to an embodiment of the present invention, and FIG. 12 is a drawing showing a state in which the interlayers are aligned by an interlayer moving robot according to an embodiment of the present invention.

[0118] Referring to FIGS. 11 and 12, a multi-joint robot (400) according to one embodiment of the present invention includes a movable robot (410) and a modular movable robot (420).

[0119] The interleaf moving robot (410) is positioned between the second conveyor (210) and the third conveyor (310), and stacks the uppermost interleaf (600) among the multiple interleafs (600) whose transport is restricted by the stopper (230) onto the upper part of the secondary battery (800) stacked in the stacking area (A).

[0120] This mobile robot (410) includes a first frame (411), a first rotating support (412), a first link (413), a second link (414), and a first working tool (415).

[0121] The first frame (411) is positioned between the second conveyor (210) and the third conveyor (310).

[0122] The first rotating support (412) is rotatably coupled to the upper part of the first frame (411).

[0123] This first rotating support (412) rotates from the first frame (411) around the Z-axis shown in the drawing.

[0124] The first link (413) is rotatably coupled to the first rotating support (412).

[0125] This first link (413) rotates around either the Y-axis or the Z-axis shown in the drawing while the first rotating support (412) is not rotated.

[0126] The second link (414) is rotatably connected at one end to the end of the first link (413).

[0127] This second link (414) rotates around the same axis as the first link (413).

[0128] That is, the second link (414) rotates around either the Y-axis or the Z-axis, which is the same as the first link (413), while the first rotational support (412) is not rotated.

[0129] The first working tool (415) is fixed to the other end of the second link (414), which is opposite to one end.

[0130] This first working tool (415) includes a first base part (415A), an adsorption part (415B), and an alignment part (415C).

[0133] And, the adsorption part (415B) adsorbs the upper surface of the uppermost sheet (600) among the multiple stacked sheets (600) that are restricted from transport by the stopper (230) on the second conveyor (210).

[0134] The alignment part (415C) is fixed in the opposite direction to the direction in which the guide part (220) is positioned in the first base part (415A) as shown in FIG. 12.

[0135] And, the alignment unit (415C) aligns the multiple sheets (600) that are manually stacked on the second conveyor (210) by contacting the side of the multiple sheets (600) that are manually stacked.

[0136] That is, the alignment unit (415C) can easily align the sides of the interlayer sheets (600) that are manually stacked on the second conveyor (210).

[0137] Specifically, the alignment part (415C) comes into contact with the side of the multiple stacked sheets (600) when the adsorption part (415B) adsorbs the sheet (600) located at the top of the multiple stacked sheets (600).

[0138] As a result, the alignment part (415C) can easily align the side of the inter-sheet (600).

[0139] Accordingly, in the present invention, the front of the interlayer sheet (600) stacked on the second conveyor (210) is aligned by the stopper (230), and the side of the interlayer sheet (600) is aligned by the alignment part (415C).

[0140] As a result, the present invention allows the adsorption part (415B) of the inter-sheet moving robot (410) to adsorb the same position on the upper surface of the inter-sheet (600) whenever it adsorbs the inter-sheet (600) in which a plurality of sheets are stacked.

[0141] The module mobile robot (420) is positioned between the third conveyor (310) and the waiting section, and stacks the secondary battery (800) placed on the waiting section onto the upper part of the interlayer (600) stacked in the stacking area (A).

[0145] These second rotating supports (422) (321) rotate around the Z-axis shown in FIG. 11 from the second frame (421).

[0146] The third link (423) is rotatably connected to the second rotating support (422) (321).

[0147] This third link (423) rotates around either the Y-axis or the Z-axis shown in the drawing while the second rotating support (422) (321) is not rotated.

[0148] The fourth link (424) is rotatably connected at one end to the end of the third link (423).

[0149] This fourth link (424) rotates around the same axis as the third link (423).

[0150] That is, the fourth link (424) rotates around either the Y-axis or the Z-axis, which is the same as the third link (423), while the second rotating support (422) (321) is not rotated.

[0151] The second working tool (425) is fixed to the other end of the second link (414), which is opposite to one end.

[0152] This second working tool (425) includes a second base part (425A) and a gripper (425B).

[0153] The second base part (425A) is fixed to the end of the fourth link (424) and is preferably formed in the shape of a square panel.

[0154] The gripper (425B) extends downward from the lower surface of the second base part (425A) and grips the secondary battery (800).

[0155] That is, the module mobile robot (420) can easily grasp the secondary battery (800) by means of the gripper (425B).

[0157] Hereinafter, a packaging method of an automatic secondary battery packaging device according to an embodiment of the present invention will be described in detail with reference to the attached drawings.

[0158] In order to facilitate an overall understanding of the present invention, the same reference numerals will be used for identical means regardless of the drawing number.

[0159] FIG. 13 is a flowchart showing a packaging method of an automatic secondary battery packaging device according to an embodiment of the present invention.

[0160] Referring to FIG. 13, the first conveyor (100) transfers the pallet (P) on which the lower box (B) is placed to the third conveyor (310) of the stacking section (300) (S110).

[0161] Then, the second conveyor (210) of the paper transfer unit (200) transfers multiple papers (600) (S120).

[0162] The interleaf transfer unit (200) includes a stopper (230) positioned at the end of the direction in which the interleaf (600) is transferred on the second conveyor (210).

[0163] The stopper (230) restricts the transport of the interleaf (600) by contacting the front of the interleaf (600) being transported along the second conveyor (210).

[0164] And, the stopper (230) contacts the front of the sheet (600), which is the direction in which the sheet (600) is transported, and aligns the front of the sheet (600).

[0165] Next, the third conveyor (310) transfers the pallet (P) received from the first conveyor (100) to the stacking area (A) (S130).

[0166] Next, when the sensing unit (320) of the stacking unit (300) detects the lower box (B) placed on the pallet (P) transferred to the stacking area (A), the inter-sheet moving robot (410) of the multi-joint robot (400) moves the inter-sheet (600) transferred to the second conveyor (210) to the stacking area (A) and stacks it on the lower box (B) (S140).

[0167] Here, the movable robot (410) includes a first working tool (415) fixed to the other end opposite to one end of the second link (414), and the first working tool (415) includes a first base part (415A) and an alignment part (415C).

[0168] The first base portion (415A) is fixed to the end of the second link (414), and the alignment portion (415C) is fixed in the direction opposite to the direction in which the guide portion (220) is arranged in the first base portion (415A), and aligns the multiple sheets (600) by contacting the side of the multiple stacked sheets (600).

[0169] As a result, the front of the interlayer (600) stacked on the second conveyor (210) is aligned by the stopper (230), and the side of the interlayer (600) is aligned by the alignment part (415C).

[0170] Next, the module moving robot (420) of the multi-joint robot (400) stacks the secondary battery (800) placed on the standby part onto the interlayer (600) stacked on the lower box (B) to form a stacked member (700) (S150).

[0171] As described above, the interlayer (600) and the secondary battery (800) are stacked in an intersecting manner to form a first stacked member (701), a second stacked member (702), and a third stacked member (703).

[0172] The first stacked member (701) is formed by stacking a secondary battery (800) and a paper sheet (600) in order on a lower box (B) placed on a pallet (P), the second stacked member (702) is formed by stacking a secondary battery (800) and a paper sheet (600) in order on top of the first stacked member (701), and the third stacked member (703) is formed by stacking a secondary battery (800) and a paper sheet (600) in order on top of the second stacked member (702).

[0173] When the first sensor (322) detects the lower box (B) placed on the pallet (P) in the stacking area (A), the transfer of the third conveyor (310) stops and the first stacking member (701) is stacked on the lower box (B).

[0174] And, when the second sensor (323) detects the first stacked member (701) stacked on the lower box (B), the second stacked member (702) is stacked on top of the first stacked member (701).

[0175] And, the third stacked member (703) is stacked on top of the second stacked member (702) when the third sensor detects the second stacked member (702) stacked on the first stacked member (701).

[0176] Meanwhile, although the laminated member (700) of the present invention has been described as being composed of a first laminated member (701) to a third laminated member (703), it may be composed of more than the third laminated member (703) and less than the second laminated member (702) depending on the usage environment.

[0177] Accordingly, the number of sensors can also be changed in the same way depending on the number of stacked members (700).

[0178] And, when the third conveyor (310) detects the third stacked member (703) of the stacked member (700) through the fourth sensor (325) of the detection unit (320), the stacked member (700) is transferred to the fourth conveyor (500) (S160).

[0180] Hereinafter, the step (S140) of moving the interleaving sheet (600) to the stacking area (A) and stacking it on the lower box (B) is explained in detail with reference to the drawings.

[0181] Referring to FIG. 14, the step of moving the interleaving paper (600) according to one embodiment of the present invention to a stacking area (A) and stacking it on a lower box (B) involves the first rotating support (412) of the interleaving paper moving robot (410) rotating so that the first link (413) and the second link (414) of the interleaving paper moving robot (410) face the direction in which the second conveyor (210) is arranged (S141).

[0182] Next, the first link (413) and the second link (414) rotate toward the interdigital sheet (600) (S142).

[0183] Next, the adsorption part (415B) of the first work tool (415) adsorbs the interleaf (600) (S143).

[0184] Next, the first link (413) and the second link (414) rotate in the opposite direction to the direction in which the second conveyor (210) is positioned (S144).

[0185] Next, the first rotating support (412) is rotated so that the first link (413) and the second link (414) face the stacking area (A) direction (S145).

[0186] Next, the first link (413) and the second link (414) rotate toward the stacking area (A) (S146).

[0187] Next, the interleaf (600) adsorbed by the adsorption part (415B) is stacked on the lower box (B) placed on the pallet (P) (S147).

[0189] Hereinafter, the step (S150) of forming a laminated member (700) is described in detail with reference to the drawings.

[0190] Referring to FIG. 15, the step of forming a stacked member (700) according to an embodiment of the present invention is to rotate the second rotating support (422) (321) of the module moving robot (420) so that the third link (423) and the fourth link (424) of the module moving robot (420) face the direction of the standby part where the secondary battery (800) is seated (S151).

[0191] Next, the third link (423) and the fourth link (424) rotate toward the waiting section (S152).

[0193] Next, the third link (423) and the fourth link (424) rotate in the opposite direction to the direction in which the standby section is positioned (S154).

[0194] Next, the second rotating support (422) (321) is rotated so that the third link (423) and the fourth link (424) face the stacking area (A) direction (S155).

[0195] Next, the third link (423) and the fourth link (424) rotate toward the stacking area (A) (S156).

[0196] Next, the secondary battery (800) held by the gripper (425B) is stacked on the interlayer (600) (S157).

[0198] Hereinafter, other embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0199] The same reference numerals are used for configurations identical to those described in the aforementioned embodiments, and a detailed description thereof is omitted.
