Technical Field

[0003] This application claims priority to Korean Patent Application No. 2020-0036740, filed on Mar. 26, 2020, the disclosure of which is incorporated herein by reference in its entirety.

[0004] The present invention relates to a battery pack loading device and a battery pack loading method using the same, and more particularly, to a battery pack loading device capable of improving safety and operability when loading heavy batteries and a battery pack loading method using the same. Background Art

[0005] Secondary batteries are highly suitable for products and have electrical properties such as high energy density, so secondary batteries have been widely used in electric vehicles (EV) or hybrid electric vehicles (HEV) and portable devices driven by electric drive sources. In addition to the main advantage of being able to significantly reduce the use of fossil fuels, secondary batteries do not produce byproducts due to the use of energy, so such secondary batteries have attracted attention as a new energy source that can improve environmental friendliness and energy efficiency.

[0006] Currently, widely used secondary batteries include lithium-ion batteries, lithium polymer batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and nickel-zinc batteries. The operating voltage of a unit secondary battery cell, i.e., a unit battery cell, is about 2.5 V to 4.5 V. Therefore, in the case where an output voltage higher than the above operating voltage is required, a plurality of battery cells can be connected in series to form a battery pack.

[0007] In addition, a plurality of battery cells may be connected in parallel to each other according to a desired charge and discharge capacity of the battery pack to constitute a battery pack. Therefore, the number of battery cells included in the battery pack may be variously set according to a desired output voltage or charge and discharge capacity.

[0008] In the case where a plurality of battery cells are connected in series / parallel to each other to constitute a battery pack, a battery module including at least one battery cell may be first manufactured, and a battery pack may be manufactured using at least one battery module and other components, which is a general method. Here, according to various required voltage and capacity conditions, a battery pack including at least one battery module may be provided for home use, or a battery rack including at least one battery pack may be combined to constitute an energy storage system for industrial use.

[0009] Meanwhile, there is a case where the battery pack must be rotated before being loaded into the battery rack, that is, the battery pack must be turned upside down. The reason for this is that, for example, a plurality of battery packs must be received in a multi-layer structure and then must be electrically connected to each other, and at this time, it is necessary to centrally arrange the connection wires as much as possible on one side so as to easily manage the connection wires while minimizing the length of each connection wire. However, since the weight of one battery pack is about 100 kg, it is difficult for a worker to turn the battery pack upside down alone. Even if it is possible, there is a high probability that an accident will occur, whereby safety and operability may deteriorate.

[0010] Figure 1 is a perspective view showing the rotation of a battery module using a conventional rotating device. Figure 1 , a rotating device is shown as follows: the rotating device is configured to insert the battery module 10 into a space defined by the first wall member 21, the second wall member 22, and the third wall member 23 (these wall members are configured to wrap the battery module 10), and use the support unit 40 to pull the wall members so as to rotate the battery module 10 90 degrees based on the fixing unit 30. However, since the conventional rotating device is manufactured based on the battery module 10, it is difficult to use the conventional rotating device when the battery module is heavy. In particular, the rotatable angle is limited to 90 degrees.

[0042] In the present application, it should be understood that the terms "including", "having", "comprising", etc. specify the presence of the described features, numbers, steps, operations, elements, parts or their combinations, but do not exclude the presence or addition of one or more other features, numbers, steps, operations, elements, parts or their combinations.

[0043] In addition, in all drawings, the same reference numerals will be used to refer to parts that perform similar functions or operations. In the specification, where a part is referred to as being "connected to" another part, not only the part may be directly connected to the other part, but the part may be indirectly connected to the other part via another part. In addition, including a certain element does not mean excluding other elements, but means that such elements may be further included, unless otherwise specified.

[0044] Hereinafter, a battery pack loading device and a battery pack loading method using the same according to the present invention will be described with reference to the accompanying drawings.

[0045] In describing a battery pack, a direction in which the length of the battery pack is relatively longer is defined as a longitudinal direction, and a direction in which the length of the battery pack is relatively shorter is defined as a lateral direction.

[0046] Figure 2 is a perspective view of a battery pack loading device according to a preferred embodiment of the present invention, Figure 3 is a front view of a rotating unit in a battery pack loading device according to a preferred embodiment of the present invention, Figure 4 is a sectional view showing a placement unit of a battery pack loading device according to a preferred embodiment of the present invention, Figure 5 2 is a perspective view showing a rotating unit of a battery pack loading device according to a preferred embodiment of the present invention. Figures 2 to 5 , a battery pack loading device according to the present invention configured to load a battery pack B includes a seating unit 100 , a rotating unit 200 , a first transfer unit 300 and a second transfer unit 400 .

[0047] First, the placement unit 100 includes: a fixed support 110 having a predetermined area; a movable support 120 located above the fixed support 110, the movable support 120 being configured to be in close contact with the bottom surface of the battery pack B to be loaded in the battery rack; and a connecting shaft 130 configured to connect the fixed support 110 and the movable support 120 to each other.

[0048] More specifically, the fixed support 110 configured to stably support the moving support 120 may include a flat plate and a plurality of supporting legs or a plurality of frames. However, the configuration of the fixed support is not particularly limited as long as the fixed support can support the moving support 120 therebelow.

[0049] The shape or size of the movable support 120 is not particularly limited as long as the movable support can allow the battery pack B to be stably placed thereon. However, since the opposite ends of the battery pack B must be fixed by the clamping parts 221 when the battery pack B is rotated by a predetermined angle, it is preferred that the movable support 120 is not located near the opposite ends of the battery pack B, and it is more preferred that a side plate configured to support the side surface of the battery pack B is further provided.

[0050] Meanwhile, at least one first rotating roller 121 is provided on the upper surface of the moving support 120. Therefore, when the battery pack B is in close contact with the clamping portion 221, even when the battery pack is placed on the upper surface of the moving support 120 and the center of the moving support 120 and the center of the battery pack B are not precisely aligned with each other, the battery pack can be easily moved to a desired position.

[0051] As an example, in the case where the battery pack B is placed on the moving support 120 in a state where it is biased to one side (X-axis direction) of the moving support 120, as shown in FIG. Figure 4 As shown in (a), one of the clamping parts 221 connected to the pair of rotating plates 220 first comes into close contact with one end of the battery pack biased to one side of the moving support 120 because the clamping part approaches the battery pack B from opposite sides at the same speed. At this time, because the bottom surface of the battery pack B is in close contact with the first rotating roller 121 ( Figure 4(b)), so the battery packs B can be evenly located on the moving support 120.

[0052] As described above, since the first rotating roller 121 can allow the battery pack B to be easily aligned and minimize friction during alignment, damage to the battery pack B can be prevented and operability can be improved.

[0053] The length of the connecting shaft 130 between the fixed support 110 and the movable support 120 is adjustable to move the movable support 120 upward and downward (Y-axis direction). The configuration of the connecting shaft 130 is not particularly limited as long as the connecting shaft can perform upward and downward movement.

[0054] Meanwhile, the battery pack B includes a plurality of unit modules, and each unit module is configured such that one or more battery cells are connected to each other in series or in parallel. The battery cells, unit modules, and battery pack are general configurations, and thus a detailed description thereof will be omitted.

[0055] Next, the rotating unit 200 will be described, which is configured to rotate the battery pack B mounted on the moving support 120 by 180 degrees based on the upper surface of the moving support 120. The rotating unit 200 includes a pair of first support fixtures 210 spaced apart from each other by a predetermined distance and a rotating plate 220 provided at the inner side of each of the pair of first support fixtures 210, the rotating plate 220 being extendable toward the battery pack B or retractable from the battery pack B, and being rotatable up to 360 degrees.

[0056] Specifically, in a state in which the seating unit 100 is located between the pair of first supporting fixtures 210 , the pair of first supporting fixtures 210 are spaced apart from each other by a predetermined distance and serve to support the corresponding rotating plates 220 .

[0057] The rotating plate 220 is disposed at the inner side of each first support fixture 210 to face the placement unit 100, and the rotating plate 220 includes a clamping portion 221 and a sensor 222, and the clamping portion 221 is configured to hold and fix the vicinity of a corresponding one of the opposite ends of the battery pack B. Specifically, a pair of clamping portions 221 are disposed at a corresponding one of the rotating plates 220, and each clamping portion 221 is configured to have a "[" shape so as to hold the lateral corner of the battery pack B. In addition, it is preferred that a pad 221' is further provided at the inner surface of the clamping portion 221. The reason is that when the clamping portion 221 holds and fixes the corner of the battery pack B, it is possible to prevent slippage between the clamping portion 211 and the battery pack B or damage to the clamping portion and the battery pack.

[0058] Here, the pad may be made of a material exhibiting predetermined elasticity and roughness, such as rubber. However, the configuration of the pad is not particularly limited as long as the pad can perform the above-mentioned function.

[0059] The sensor 222 located at the center of the inner side of the rotating plate 220 prevents damage to the battery pack B and also determines whether the battery pack B has been properly fixed by the clamping portion 221 .

[0060] As described above, a pair of rotating plates 220, each of which is provided with the clamping parts 221, approaches the battery pack B from opposite sides at the same speed to fix opposite ends of the battery pack B. In the case where the rotating plates 220 are excessively extended toward the battery pack B, the vicinity of the end of the battery pack B may be damaged. On the other hand, in the case where the rotating plates are not sufficiently extended, the battery pack B may not be properly fixed by the clamping parts 221, whereby a serious accident may occur.

[0061] However, the above problem can be solved by providing the sensor 222. As an example, the sensor 222 can be a button-type sensor capable of sensing pressure. One or more sensors 222 can be installed on each rotating plate 220, and control can be performed so that when the measurement value of the sensor 222 reaches a predetermined range, the extension of the rotating plate 220 is stopped.

[0062] Figure 6 is a cross-sectional view illustrating operations of a seating unit and a rotating unit configured to rotate a battery pack in a battery pack loading device according to a preferred embodiment of the present invention.

[0063] The operation method for rotating the battery pack B placed on the seating unit 100 by a predetermined angle, for example, 180 degrees, will be described. This method allows one surface of the battery pack facing the moving support 120 to face upward by the operation of the seating unit 100 and the rotating unit 200 having the above-mentioned configuration. First, the opposite sides of the battery pack B placed on the moving support 120 are held in a close contact state by the clamping portions 221 ( Figure 6 (a)). Then, the connecting shaft 130 of the movable support 120 moves downward (in the Y-axis direction) to ensure a space for the battery pack B to rotate ( Figure 6 (b)), and the rotating plate 220 connected to the clamping portion 221 rotates to rotate the battery pack B ( Figure 6 (c)).

[0064] Finally, the connecting shaft 130 moves upward (in the Y-axis direction) and returns to its original position. As a result, the movable support member 120 supports the battery pack B ( Figure 6 (d)).

[0065] Next, the first transfer unit 300 will be described, which is configured to lift the battery pack B placed on the moving support 120 and move the battery pack to the second transfer unit 400. Of course, it is obvious that the first transfer unit 300 can also be used when the battery pack B that needs to be rotated is transferred to the moving support 120.

[0066] and Figure 2 Reference together Figure 7 , Figure 7 It is a stereoscopic view of a first transfer unit in a battery pack loading device according to a preferred embodiment of the present invention, wherein the first transfer unit 300 includes a transfer plate 310, a hook 320 of the transfer plate 310, and a moving shaft 330, wherein the moving shaft 330 is configured to move the transfer plate 310 vertically and horizontally.

[0067] The hook 320 is connected to the bottom surface or the side surface of the transfer plate 310, and the hook 320 is configured to firmly hold the battery pack B placed on the placement unit 100. When provided at the side surface of the transfer plate, the hook may have an approximately L-shaped shape. That is, the hook 320 may include a vertical portion 321 configured to be in close contact with the lateral side surface of the battery pack B and a horizontal portion 322 configured to be in close contact with the lateral bottom surface of the battery pack B.

[0068] Preferably, the two hooks 320 are formed in pairs in a manner facing each other so as to be in close contact with the lateral side surface and the lateral bottom surface of the battery pack B, so that the battery pack B can be stably moved to a predetermined position after being lifted, specifically to the second transfer unit. More preferably, at least two pairs of hooks are provided in the longitudinal direction of the battery pack B.

[0069] Here, it is apparent that the hook 320 can move in the lateral direction of the battery pack B so as to hold or release the battery pack B.

[0070] The moving shaft 330 connected to the upper portion of the transfer plate 310 is configured to move the transfer plate 310 to a desired position, and can rotate 360 ​​degrees in addition to moving upward and downward (Y-axis direction).

[0071] Figure 8 FIG. 2 is a perspective view of a second transfer unit in a battery pack loading device according to a preferred embodiment of the present invention. Figure 8and Figure 2 The second transfer unit 400 is described.

[0072] The second transfer unit 400 is configured to transfer the battery pack B to the front of the receiving space S of the battery rack, which will be described below, and includes a second support fixture 410, a shelf 420 connected to the second support fixture 410, and a second rotating roller 430 located on the shelf 420.

[0073] The second support fixture 410 configured to support the shelf 420 is provided with a lifting chain (not shown) configured to position the shelf 420 at a desired height. The second rotating roller 430 on the shelf 420 is structurally the same as the first rotating roller 121, and is configured to allow the battery pack B to move even with a small force when the battery pack B is received in the battery rack 500, thereby facilitating work.

[0074] Meanwhile, the battery pack 500 includes a vertical frame 510 and a horizontal frame 520. A plurality of vertical frames 510, for example, four vertical frames, may be provided to be spaced apart from each other by a predetermined distance so as to support the corners of the battery pack having an approximately hexahedral shape. However, the number of the vertical frames may be changed as needed. For example, six vertical frames may be provided.

[0075] The horizontal frame 520 is located inside the vertical frame 510 so as to receive a plurality of battery packs in a multi-stage manner. Specifically, the horizontal frame 520 includes a vertical support portion fixed to the inner surface of the vertical frame 510 and a horizontal support portion vertically extending from the lower edge of the vertical support portion, thereby the horizontal frame has an approximately L-shaped shape.

[0076] A plurality of horizontal frames 520 (each of which is constructed in the above-described manner) are arranged to be spaced a predetermined distance apart from each other in the height direction of the vertical frame 520, so that the lower edge of the battery pack B is supported by a receiving space S (i.e., a pair of horizontal support portions facing each other) configured to receive the battery pack B therein.

[0077] Next, a method of loading the battery pack B into the battery rack will be described. Fig. 9 is a flow chart showing a method of loading a battery pack into a battery rack using the battery pack loading device according to the present invention.

[0078] refer to Fig. 9The battery pack loading method according to the present invention includes: a first step: placing the battery pack B on the movable support 120; a second step: moving a pair of clamping parts 221 to fix the opposite ends of the placed battery pack B; a third step: moving the movable support 120 downward; a fourth step: rotating the battery pack B so that the upper surface of the battery pack B faces downward; a fifth step: moving the movable support 120 to its original position; a sixth step: moving the pair of clamping parts 221 to its original position; a seventh step: moving the rotated battery pack B; an eighth step: positioning the battery pack B in front of the receiving space S of the battery rack 500; and a ninth step: receiving the battery pack B in the receiving space S of the battery rack 500.

[0079] Specifically, in the first step of placing the battery pack B on the moving support 120 , the battery pack B stored in a separate location is placed on the upper surface of the moving support 120 using the first transfer unit 300 .

[0080] In the second step, the pair of clamping parts 221 are moved to hold and fix the four corners of the battery pack B.

[0081] In the third step, in a state where the battery pack B is fixed, the moving support 120 moves downward to ensure a space in which the battery pack B can rotate.

[0082] In the fourth step, the pair of clamping parts 221 are rotated 180 degrees, whereby the battery pack B is also rotated 180 degrees so that the upper surface of the battery pack B faces downward.

[0083] In the fifth step, the moving support 120 moves upward to its original position and again supports the battery pack in a state of being rotated 180 degrees so as to separate the clamping portion 221 from the battery pack.

[0084] In the sixth step, the clamping portion 221 holding and fixing the battery pack B is moved to its original position. In the seventh step, the battery pack B in the rotated state is placed on the second rotating roller 430 located on the upper surface of the shelf 420 of the second transfer unit 400 using the first transfer unit 300 .

[0085] In the eighth step, the shelf 420 of the second transfer unit 400 moves upward or downward so that the battery pack B is located in front of the receiving space S of the battery rack 500 in which the battery pack will be received.

[0086] In the ninth step, force is applied to the battery pack B located in front of the receiving space S so that the battery pack is inserted and loaded in the battery rack 500 .

[0087] Subsequently, the first to ninth steps are repeatedly performed so that a desired number of battery packs B are received in the battery rack 500 .

[0088] Although the specific details of the present invention have been described in detail, it will be appreciated by those skilled in the art that the detailed description thereof only discloses the preferred embodiments of the present invention and therefore does not limit the scope of the present invention. Therefore, it will be appreciated by those skilled in the art that various changes and modifications are possible without departing from the category and technical ideas of the present invention, and it is obvious that such changes and modifications fall within the scope of the appended claims.
