Description

Technical Field

[0001] This disclosure relates to battery pack assembly units. Background Technology

[0002] Unlike primary batteries, which cannot be recharged, secondary batteries are typically rechargeable and dischargeable. Low-capacity secondary batteries are used in portable small electronic devices such as smartphones, feature phones, laptops, digital cameras, and camcorders, while high-capacity secondary batteries are widely used as power sources and energy storage batteries for motors in hybrid or electric vehicles. A secondary battery includes an electrode assembly containing positive and negative electrodes, a housing of the electrode assembly, and electrode terminals connected to the electrode assembly.

[0003] Secondary batteries can be used as battery packs formed by multiple cell units connected in series and / or parallel to provide high energy density. Battery packs can be formed by connecting the electrode terminals of multiple cell units to each other to meet the required power and achieve high-power secondary batteries, such as those used in electric vehicles.

[0004] Battery packs can be manufactured through multiple assembly and inspection processes, and these processes can be performed simultaneously as pallets are transported along the production line to each process location. There is an increasing demand for producing battery packs for a wider range of models, but battery pack production lines are constrained.

The terms or words used in this specification and claims should not be construed as limited to their conventional or dictionary meanings, but should be interpreted as having meanings and concepts consistent with the technical concept of this disclosure, based on the principle that the inventor can be his / her own lexicographer to appropriately define the concepts of the terms.

[0030] The embodiments described in this specification and the constructions shown in the accompanying drawings are provided as some exemplary embodiments of this disclosure and do not represent all technical concepts, aspects, and features of this disclosure. Therefore, it is understood that various equivalents and modifications may exist that can replace or modify the embodiments described herein at the time of filing this application.

[0031] It is understood that when an element or layer is referred to as being "on," "connected to," or "bonded to" another element or layer, it can be directly on, directly connected to, or directly bonded to the other element or layer, or there may be one or more intermediary elements or layers. When an element or layer is referred to as being "directly on," "directly connected to," or "directly bonded to" another element or layer, there are no intermediary elements or layers. For example, when a first element is described as being "bonded" or "connected" to a second element, the first element can be directly bonded to or connected to the second element, or the first element can be indirectly bonded to or connected to the second element via one or more intermediary elements.

[0032] In the accompanying drawings, the dimensions of various elements, layers, etc., may be exaggerated for clarity. The same reference numerals denote the same or similar elements. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Furthermore, when describing embodiments of this disclosure, the use of "may" refers to "one or more embodiments of this disclosure." When expressions such as "at least one of..." and "any one of..." are placed after a list of elements, they modify the entire list of elements, not individual elements within that list. When a list of elements A, B, and C is specified using phrases such as “at least one of A, B, and C,” “at least one of A, B, or C,” “at least one selected from the group A, B, and C,” or “at least one selected from A, B, and C,” the phrase may refer to any suitable combination (or subset) of A, B, and C and all suitable combinations (or subsets), such as A, B, C, A and B, A and C, B and C, or A and B and C. As used herein, the term “use” and its variations may be considered synonymous with the term “utilize” and its variations, respectively. As used herein, the terms “substantially,” “about,” and similar terms are used as approximate terms rather than terms of degree and are intended to explain the inherent variations in measured or calculated values ​​that would be recognized by one of ordinary skill in the art.

[0033] It is understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the teachings of the exemplary embodiments, the first element, first component, first region, first layer, or first portion discussed herein may be referred to as a second element, second component, second region, second layer, or second portion.

[0034] For ease of description, spatial relative terms such as “below,” “under,” “down,” “above,” “above,” etc., may be used herein to describe the relationship between one element or feature and another element(s) shown in the figure. It is understood that, in addition to the orientation depicted in the figure, the spatial relative terms are intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “under” other elements or features will subsequently be oriented as “above” or “above” other elements or features. Thus, the term “below” can cover both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein should be interpreted accordingly.

[0035] The terminology used herein is for the purpose of describing embodiments of this disclosure and is not intended to limit the disclosure. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “an” are intended to include the plural forms as well. It is further understood that when the terms “comprising,” “including,” and / or variations thereof are used in this specification, it indicates the presence of the stated features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0036] Furthermore, any numerical range disclosed and / or described herein is intended to include all subranges with the same numerical precision contained within the described range. For example, the range “1.0 to 10.0” is intended to include all subranges between the described minimum value 1.0 and the described maximum value 10.0 (and including both the described minimum value 1.0 and the described maximum value 10.0) (i.e., a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0), such as 2.4 to 7.6. Any maximum numerical limit described herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit described in this specification is intended to include all higher numerical limits contained therein. Therefore, in order to clearly describe any subranges contained within the range explicitly described herein, the applicant reserves the right to amend this specification (including the claims).

[0037] Referring to two compared elements, features, etc., as “identical” can mean that they are “substantially identical.” Therefore, the phrase “substantially identical” can include cases with deviations considered low in the art (e.g., 5% or less). Furthermore, when a parameter is said to be uniform in a given region, this can mean that it is uniform in terms of its mean.

[0038] Throughout the specification, unless otherwise stated, each element may be singular or plural.

[0039] When any element is described as being arranged (or located or placed) "above (or below)" or "on (or under)" a component, this can mean that the element is positioned to contact the upper (or lower) surface of the component, and it can also mean that other components may be located between the component and any element arranged (or located or placed) on (or below) the component.

[0040] Furthermore, it is understood that when an element is referred to as being "joined," "linked," or "connected" to another element, the elements can be directly "joined," "linked," or "connected" to each other, or there can be one or more intermediary elements between them through which the one element can be "joined," "linked," or "connected" to the other element. Additionally, when a part is referred to as being "electrically joined" to another part, the part can be directly electrically connected to the other part, or there can be one or more intermediary parts between them such that the part and the other part are indirectly electrically connected to each other.

[0041] Throughout this specification, when “A and / or B” is stated, unless otherwise stated, it means A, B, or A and B. That is, “and / or” includes any or all combinations of the listed items. When “C to D” is stated, unless otherwise stated, it means C or greater and D or less.

[0042] The terminology used in this specification is used to describe embodiments of this disclosure and is not intended to limit this disclosure.

[0044] Reference Figure 1 According to an embodiment of the present disclosure, the battery pack assembly unit 1 includes a tray 10, a conveyor 20, and a support fixing moving device 30.

[0045] Tray 10 provides a base for assembling battery pack 2 (see...) Figure 2 Component 3 of the battery pack 2 can be loaded and mounted on the base. The tray 10 includes a plate 11 that supports component 3 of the battery pack 2 from there and one or more support fasteners 17 that restrict the movement of component 3.

[0046] The conveyor 20 transports the pallet 10. The conveyor 20 may have a conveyor structure. The pallet 10 may be placed and loaded on the conveyor 20 and transported in the extending direction of the conveyor 20 (e.g., forward). The plate 11 of the pallet 10 may have a shape that allows it to be placed on the conveyor 20.

[0047] For example, the conveyor 20 may have a structure in which a pair of conveyor tracks 21 extend in parallel, and a rotating roller 22, which rotates in conjunction with a motor (not shown), is arranged to be exposed upward on the upper part of the conveyor tracks 21. The plate 11 may be transported forward along the conveyor 20 in conjunction with the rotation of the rotating roller 22, with the two sides of the plate 11 positioned on the conveyor tracks 21 of the conveyor 20.

[0048] A support fixing member moving device 30 is disposed above the conveyor 20 and adjusts the position of the support fixing member 17 according to the shape and size of the component 3. The position of the support fixing member 17 can be changed according to the shape and size of the component 3 by the support fixing member moving device 30. By changing the position of the support fixing member 17 as described herein, not only can a component 3 having a first shape and a first size be loaded and installed onto the pallet 10, but also a component 3 having a shape and size that are at least one different from the first shape and the first size can be loaded and installed onto the pallet 10.

[0049] Figure 2 This is an exploded perspective view schematically illustrating the main parts of an example of a battery pack assembled by a battery pack assembly unit according to an embodiment of the present disclosure.

The housing 4 may also include a cover 6 that closes the open top after the battery cells 5 and other components 3 are housed and assembled in the housing 4.

[0055] The housing 4 is located at the bottom among the components 3 constituting the battery pack 2, and may have the largest size among the components 3 constituting the battery pack 2. Among the components 3 of the battery pack 2, the housing 4 may be the first component 3 to be loaded and installed onto the tray 10. When the housing 4 is loaded onto the tray 10, the other components 3 of the battery pack 2 may be assembled onto the housing 4.

[0056] The housing 4 can be mounted on the tray 10. The housing 4 can be mounted on the plate 11 and can contact a plurality of support fasteners 17, thereby restricting it from horizontal movement. The housing 4 can contact the upper surface of the plate 11, or can be configured to be raised a predetermined height above the upper surface of the plate 11 depending on the length and arrangement of the support fasteners 17.

[0057] A groove (not shown) having a shape corresponding to at least a portion of the support fastener 17 can be formed on the housing 4 at a position corresponding to the support fastener 17. When the housing 4 is placed on the tray 10, the support fastener 17 can be fitted into the groove of the housing 4, and the housing 4 can be restricted from moving by engaging with the support fastener 17 fitted into the groove.

[0058] A groove (not shown) having a shape corresponding to the upper part of the support fastener 17 can be formed on a flange portion (not marked in the figure), the flange portion being formed to project laterally from the lower part or edge of the housing 4. The groove can be formed to be recessed upward on the bottom surface of the housing 4 or on the bottom surface of the flange portion facing the tray 10. When the upper part of the support fastener 17 has a polygonal cross-sectional shape, the groove can have a corresponding polygonal cross-sectional shape. When the upper part of the support fastener 17 has a stepped shape or inclined surface that narrows upward, the groove can have a corresponding stepped or inclined cross-sectional shape.

[0071] The support rod 171 has a rod shape and can be configured to project upward from the plate 11. Depending on the size and shape of the component 3 to be supported, the support rod 171 can have various lengths and cross-sectional shapes. The support rod 171 can have a rod shape with an overall circular cross-section.

[0072] The fastening part 172 is a device assembly for fastening to the mounting base 13 and can be integrally formed with the lower part of the support rod 171. The fastening part 172 has an external thread structure and can be detachably screwed into the fastening groove 132 of the mounting base 13. When the fastening part 172 is fastened to the fastening groove 132, the support rod 171 can be mounted and fixed in a shape that protrudes upward from the upper part of the plate 11.

[0073] The support fastener 17 can be screwed into the fastening groove 132 of the mounting base 13 via the fastening part 172. Therefore, the fastening state between the support fastener 17 and the mounting base 13 can be released by rotating the support fastener 17, which is fastened to the mounting base 13, in the opposite direction (e.g., counterclockwise). When the support fastener 17 is rotated in the opposite direction, the fastening part 172 gradually moves upward in the fastening groove 132 and eventually reaches the upper end of the fastening groove 132, thereby releasing the fastening state between the support fastener 17 and the mounting base 13.

[0074] Furthermore, the support fastener 17 can be secured to the mounting base 13 by being placed on the upper part of the mounting base 13 and rotated in the forward direction (e.g., clockwise). When the fastening part 172 is rotated in the forward direction while positioned to contact the upper part of the fastening groove 132, the fastening part 172 can gradually descend along the internal thread of the fastening groove 132 and be fastened to a predetermined depth.

[0075] The retaining part 173 is a device assembly that contacts the fastening device 31 and the clamping device 32 (described herein) of the supporting fixing moving device 30, and can be integrally formed with the upper part of the support rod 171. The retaining part 173 may include a rotating retaining part 174, a gripping retaining part 175, and a locking step 176.

[0076] The rotating retaining part 174 is a device assembly that engages with the fastening device 31 and has a cross-sectional shape other than a circular cross-section. The rotating retaining part 174 may have a polygonal cross-sectional shape and can receive rotational force output from the fastening device 31 while engaging with the fastening device 31. Since the rotating retaining part 174 has a cross-sectional shape other than a circular cross-section, the rotational force output from the fastening device 31 can be transmitted to the support fixing member 17 without loss through the rotating retaining part 174.

[0077] The gripping and holding portion 175, located below the rotating holding portion 174, is a device assembly held by the clamping device 32 and can be formed to be recessed along the outer periphery of the support rod 171. Since the gripping and holding portion 175 is formed to be recessed along the outer periphery of the support rod 171, a locking step 176 can be formed between the rotating holding portion 174 and the gripping and holding portion 175. The gripping and holding portion 175 can have a circular cross-sectional shape. Because the gripping and holding portion 175 has a circular cross-sectional shape and the rotating holding portion 174 has a polygonal cross-sectional shape, a locking step 176 can be formed between the rotating holding portion 174 and the gripping and holding portion 175.

[0078] The gripping and holding part 175 is gripped by the gripping fingers 327 of the clamping device 32 (see...) Figure 14 (As described herein) In the clamped state, the upper part of the gripping finger 327 can be locked by the locking step 176. In other words, when the gripping holding part 175 is clamped by the gripping finger 327, the locking step 176 of the support fixing member 17 can be positioned above the upper part of the gripping finger 327. Therefore, the support fixing member 17 can be restricted and prevented from sliding downward or separating from the gripping device 32 when it is clamped and moved by the clamping device 32.

[0079] Figure 5 This is a schematic plan view of a tray according to an embodiment of the present disclosure.

[0080] Reference Figure 5 According to this disclosure, the tray 10 may include a first region se1, a second region se2 and a third region se3. The first region se1 is provided with a first component 3A of a first battery pack 2A, the second region se2 is provided with a second component 3B of a second battery pack 2B, and the third region se3 is shared by a portion of the first region se1 and a portion of the second region se2.

[0081] Multiple mounting bases 13 may be distributed across the first region se1, the second region se2, and the third region se3. The mounting bases 13 may be classified as first mounting base 14, second mounting base 15, and third mounting base 16 according to their mounting location within the multiple regions including the first region se1, the second region se2, and the third region se3. Each of the multiple support fasteners 17 may be selectively coupled to the first mounting base 14, the second mounting base 15, and the third mounting base 16.

[0082] One or more first mounting bases 14 may be disposed in a first region se1. If one or more first mounting bases 14 are located in a third region se3, the first mounting bases 14 may be disposed in the first region se1. One or more second mounting bases 15 may be disposed in a second region se2. If one or more second mounting bases 15 are located in the third region se3, the second mounting bases 15 may be disposed in the second region se2. One or more third mounting bases 16 may be disposed outside the second region se2. The third mounting bases 16 may be disposed outside the second region se2 but may also be disposed in the first region se1.

[0083] Depending on whether the support fastener 17 supports the first component 3A or the second component 3B, the support fastener 17 can be classified as a first support fastener 18 and a second support fastener 19. The support fastener 17 can be classified as a first support fastener 18 configured to support the first component 3A and a second support fastener 19 configured to support the second component 3B.

[0084] Reference Figure 3 The first support fastener 18 and the second support fastener 19 may have different lengths or shapes. When the first component 3A has a larger volume and width than the second component 3B, the first support fastener 18 may have a longer length than the second support fastener 19. For example, the second support fastener 19 may have a shorter length than the first support fastener 18 to the extent that the second support fastener 19 does not interfere with the first component 3A when it contacts the first support fastener 18.

[0085] Figure 6 This is a conceptual diagram illustrating a first area of ​​a tray according to an embodiment of the present disclosure. Figure 7 This is a conceptual diagram illustrating a second area of ​​a tray according to an embodiment of the present disclosure. Figure 8 This is a conceptual diagram illustrating a first region, a second region, and a third region of a tray according to an embodiment of the present disclosure.

[0086] To facilitate easy differentiation between the first support fastener 18 and the second support fastener 19, Figures 6 to 8 In the diagram, ◎ represents the first support and fixing component, ○ represents the second support and fixing component, and the mounting base 13 is omitted.

[0087] Reference Figure 6 and Figure 8The first component 3A may have a width greater than half the width of the plate 11. The first component 3A may be placed at the center of the tray 10. The area where the first component 3A is placed may be designated as a first area se1. The first component 3A may be supported by a plurality of first support fasteners 18 disposed in the first area se1.

[0088] At this point, some of the plurality of first support fasteners 18 can be positioned within the third region se3. Furthermore, the first support fasteners 18 can also be positioned at locations corresponding to the edges of the first component 3A. At least some of the plurality of first support fasteners 18 can be positioned at corners corresponding to the first component 3A.

[0089] Reference Figure 7 and Figure 8 The second component 3B may have a width less than half the width of the plate 11. Multiple second components 3B may be placed on the tray 10. Two second components 3B may be placed parallel to each other in the direction of transport by the conveyor 20 (e.g., in the front-to-back direction). The area where the second components 3B are placed may be designated as a second area se2. The second components 3B may be supported by multiple second support fasteners 19 disposed in the second area se2.

[0090] At this point, some of the plurality of second support fasteners 19 can be positioned in the third region se3. Furthermore, the second support fasteners 19 can be positioned at locations corresponding to the edges of the second component 3B. At least some of the plurality of second support fasteners 19 can be positioned at corners corresponding to the second component 3B.

[0091] Figure 9 This is a perspective view showing the state in which a first component, according to an embodiment of the present disclosure, is placed on a first area of ​​a tray.

[0092] During the manufacturing of the first battery pack 2A, such as Figure 3 and Figure 6 As shown, at the first process position where the support fixing moving device 30 is installed, a plurality of first support fixings 18 can be positioned in the first region se1 of the tray 10. At this time, as Figure 8 As shown, some of the first support fasteners 18 can be positioned in the third region se3.

[0093] Subsequently, pallet 10 can be transported to the second process position by conveyor 20. When pallet 10 arrives at the second process position, the first component 3A can be transported as follows: Figure 9The double-dotted line indicates that it is loaded onto the tray 10 and can contact a plurality of first support fasteners 18 to restrict its movement in the horizontal direction (in the front-to-back and left-to-right directions). The first component 3A may be the housing 4 of the first battery pack 2A. In this case, the plurality of first support fasteners 18 among the plurality of support fasteners 17 can effectively perform the function of contacting the first component 3A and restricting the movement of the first component 3A.

[0094] With the first component 3A positioned in the first region se1 as described herein, among the plurality of second support fasteners 19, the second support fastener 19 disposed in the third region se3 can be positioned below the first component 3A. In this case, the length of the second support fastener 19 can be shorter than that of the first support fastener 18 so as not to interfere with the first component 3A. With the first component 3A in contact with and supported by the first support fastener 18, the bottom surface of the first component 3A can be raised above the second support fastener 19 disposed in the third region se3.

[0095] Furthermore, with the flange portions formed on the front and rear portions of the first component 3A in contact with and supported by the first support fastener 18, the bottom surface of the first component 3A positioned below the flange portions can contact the second support fastener 19 disposed in the third region se3, and can be held and supported by the second support fastener 19. By forming the second support fastener 19 as shorter than the first support fastener 18 as described herein, the process of moving the second support fastener 19 disposed in the third region se3 to the outside of the first region se1 during the assembly of the first component 3A can be omitted.

[0096] The first component 3A may have a cuboid box shape and may have a width greater than half the width of the plate 11. A plurality of first support fasteners 18 may be arranged along the front and rear of the first component 3A. (Refer to...) Figure 8 and Figure 9 Three first support fasteners 18 may contact the front portion of the first component 3A, and three first support fasteners 18 may contact the rear portion of the first component 3A. By contacting the multiple first support fasteners 18 at multiple points as described herein, the first component 3A may be supported by the first support fasteners 18 while its movement is restricted.

[0097] A groove may be formed on the portion of the first component 3A that contacts the first support member 18, and the upper part of the first support member 18 may be inserted into the groove. The first component 3A may be restricted from horizontal movement by being engaged with the first support member 18 fitted into the groove.

[0098] Reference Figure 9 Four second support fasteners 19 can be positioned in the third region se3, and when the first component 3A is positioned in the first region se1, the edge of the first component 3A can be supported by six first support fasteners 18, and simultaneously, the rectangular bottom surface of the first component 3A can be supported by four second support fasteners 19. At this time, a groove corresponding to the upper shape of the second support fasteners 19 can be formed in the portion of the first component 3A that contacts the second support fasteners 19, and the second support fasteners 19 can be inserted into the groove. The first component 3A can be restricted from horizontal movement by being engaged with the first and second support fasteners 18 and 19 fitted into the groove.

[0099] Subsequently, with the first component 3A loaded on the tray 10, the tray 10 can be transported to the third process position via the conveyor 20. When the tray 10 arrives at the third process position, multiple battery cells 5 can be accommodated and assembled as described above. Figure 9 The first component 3A is depicted by the double-dotted line. Subsequently, the first battery pack 2A can undergo further assembly processes to be manufactured and completed.

[0100] Figure 10 This is a perspective view schematically illustrating another example of a plate according to an embodiment of the present disclosure. Figure 11 This is a perspective view showing the state in which the second component, according to an embodiment of the present disclosure, is placed on a second area of ​​a tray.

[0101] Subsequently, during the manufacture of the second battery pack 2B using the same tray 10, a plurality of first support fasteners 18 positioned in the third region se3 can be moved outside the second region se2 from a first process position in which the support fastener moving device 30 is installed. The plurality of first support fasteners 18, which are attached to the first mounting base 14 in the third region se3 during the manufacture of the first battery pack 2A, can be repositioned and attached to the third mounting base 16 during the manufacture of the second battery pack 2B.

[0102] At this time, as Figure 3 and Figure 6 The plurality of first support fasteners 18 shown, which are fastened to the first mounting base 14, can be released from the first mounting base 14 and then moved by the support fastener moving device 30 as shown. Figure 7 and Figure 10 The ground shown moves toward the third mounting base 16 and is secured to the third mounting base 16.

[0103] Subsequently, pallet 10 can be transported to the second process position by conveyor 20. When pallet 10 arrives at the second process position, the second component 3B can be... Figure 11The double-dotted line indicates that it is loaded onto the tray 10 and can contact multiple second support fasteners 19 to restrict its movement in the horizontal direction (in the front-to-back and left-to-right directions). The second component 3B can be the housing 4 of the second battery pack 2B. In this case, multiple second support fasteners 19 among the multiple support fasteners 17 can effectively perform the function of contacting the second component 3B and restricting the movement of the second component 3B.

[0104] The second component 3B may have a cuboid box shape with a width less than half the width of the plate 11, and two second components 3B may be placed on the tray 10. The two second components 3B may be positioned spaced apart from each other in the front-to-back direction. A plurality of second support fasteners 19 may be provided at positions corresponding to the corners of the second components 3B.

[0105] Reference Figure 8 and Figure 11 Each of the four second support fasteners 19 can contact a corner of one of the second components 3B, and each of the four second support fasteners 19 can contact a corner of another second component 3B. By contacting the multiple second support fasteners 19 at multiple points as described herein, the two second components 3B can be supported by the second support fasteners 19, while their movement is restricted.

[0106] A groove may be formed in the portion of the second component 3B that contacts the second support fastener 19, and the upper part of the second support fastener 19 may be inserted into the groove. The second component 3B may be restricted from horizontal movement by being engaged with the second support fastener 19 fitted into the groove.

[0107] Subsequently, with the second component 3B loaded onto the tray 10, the tray 10 can be transported to the third process position via the conveyor 20. When the tray 10 arrives at the third process position, multiple battery cells 5 can be accommodated and assembled as described above. Figure 11 The second component 3B is indicated by the double-dotted line. Subsequently, the second battery pack 2B can undergo further assembly processes to be manufactured and completed.

[0108] Figure 12 This is a perspective view schematically illustrating yet another example of a plate according to an embodiment of the present disclosure. Figure 13 This is a perspective view showing the state in which a third component, according to an embodiment of the present disclosure, is placed on a second area of ​​a tray.

[0109] Reference Figure 8Some of the multiple mounting bases 13 can be densely arranged within a set distance d1 to form groups g1 and g2. The groups g1 and g2 of the mounting bases 13 can form one group or multiple groups in the first region and the second region. The groups g1 and g2 of the mounting bases 13 can be formed at positions corresponding to the edge of the first component 3A, and can also be formed at positions corresponding to the edge of the second component 3B.

[0110] As an example, the mounting base 13 can be arranged to form a first group g1 and a second group g2. The first group g1 can be formed by arranging a plurality of second mounting bases 15 within a set distance d1 at a first position P1, which is a corner of the second component 3B. The second group g2 can be formed by arranging a plurality of second mounting bases 15 within a set distance d1 at a second position P2, which is another corner of the second component 3B.

[0111] The first group g1 can be formed by arranging two mounting bases 13 in parallel in the left-right direction. The second group g2 can be formed by arranging two mounting bases 13 in parallel in the left-right direction. The interval between the first position P1 and the second position P2 can be greater than the set distance d1.

[0112] When manufacturing the second battery pack 2B, the second support fastener 19 can be fastened to one of the plurality of second mounting bases 15 forming the first group g1. Furthermore, the second support fastener 19 can be fastened to one of the plurality of second mounting bases 15 forming the second group g2. When manufacturing the third battery pack 2C, the second support fastener 19 can be moved and fastened to another of the plurality of second mounting bases 15 forming the first group g1 by the support fastener moving device 30. Furthermore, the second support fastener 19 can be moved and fastened to another of the plurality of second mounting bases 15 forming the second group g2.

[0113] When the second battery pack 2B and the third battery pack 2C each have a width less than half the width of the plate 11, two or more second components 3B or third components 3C can be loaded onto the tray 10. Alternatively, one or more second components 3B and one or more third components 3C can be loaded together onto the tray 10.

[0114] The third component 3C may have a shape or size different from that of the second component 3B. For example, the third component 3C may have the same cuboid shape as the second component 3B, but with a smaller left and right width than the second component 3B.

[0115] When the second component 3B has a larger left and right width than the third component 3C, and multiple second battery packs 2B are manufactured using a single tray 10, such as Figure 10 and Figure 11As shown, the second support fastener 19 can be fastened to the second mounting base 15 within the first group g1, which is relatively close to the left or right edge of the tray 10. Furthermore, the second support fastener 19 can be fastened to the second mounting base 15 within the second group g2, which is relatively close to the left or right edge of the tray 10.

[0116] When the second battery pack 2B and the third battery pack 2C are manufactured simultaneously using the same tray 10 after the second battery pack 2B has been manufactured, such as Figure 12 and Figure 13 As shown, the second support fastener 19 can be moved and secured to the second mounting base 15 within the first group g1 via the support fastener moving device 30. This second mounting base 15 is spaced apart from the left or right edge of the tray 10. Furthermore, the second support fastener 19 can be moved and secured to the second mounting base 15 within the second group g2, which is also spaced apart from the left or right edge of the tray 10. Therefore, the lateral distance between the second support fasteners 19 positioned at the first position P1 and the second position P2 can be further reduced.

[0117] Subsequently, pallet 10 can be transported to the second process position by conveyor 20. When pallet 10 arrives at the second process position, the second component 3B and the third component 3C can be transported as follows: Figure 13 The components indicated by the double-dotted lines are loaded onto the tray 10 and can contact multiple second support fasteners 19 to restrict their movement in the horizontal direction (both front-to-back and left-to-right). At this time, the second component 3B and the third component 3C can contact the second support fasteners 19 positioned at the first position P1 and the second position P2. The second component 3B can be the housing 4 of the second battery pack 2B, and the third component 3C can be the housing 4 of the third battery pack 2C.

[0118] The second component 3B may have a cuboid box shape with a width less than half the width of the plate 11, and may be placed on the rear of the tray 10. The third component 3C may have a cuboid box shape with a width less than half the width of the plate 11, and may be placed on the front of the tray 10. A plurality of second support fasteners 19 may be provided at positions corresponding to the corners of each of the second component 3B and the third component 3C.

[0119] Four second support fasteners 19 may respectively contact the corners of the second component 3B and the third component 3C. By contacting the multiple second support fasteners 19 at multiple points as described herein, the second component 3B and the third component 3C can be supported by the second support fasteners 19, while their movement is restricted.

[0120] A groove may be formed in the portion of each of the second component 3B and the third component 3C that contacts the second support fastener 19, and the upper portion of the second support fastener 19 may be inserted into the groove. The second component 3B and the third component 3C may be restricted in their horizontal movement by being engaged with the second support fastener 19 fitted into the groove.

[0121] Subsequently, with the second component 3B and the third component 3C loaded together on the tray 10, the tray 10 can be transported to the third process position via the conveyor 20. When the tray 10 arrives at the third process position, multiple battery cells 5 can be accommodated and assembled as shown in the image. Figure 13 The second battery pack 2B and the third battery pack 3C are indicated by the double-dotted lines. The second battery pack 2B and the third battery pack 2C can undergo further assembly processes to be manufactured and completed simultaneously.

[0122] According to this disclosure, such as Figures 5 to 11 As shown, some of the support fasteners 17 can be moved to the interior and exterior of each of the first region se1, the second region se2, and the third region se3. By undergoing a process of changing the arrangement of the support fasteners 17 as described herein, various battery packs 2 of different specifications can be manufactured using the same tray 10.

[0123] Furthermore, according to this disclosure, such as Figures 10 to 13 As shown, some of the support fasteners 17 located in each of the first region se1, the second region se2, and the third region se3 can be slightly moved within a set distance d1. By undergoing a process of changing the arrangement of the support fasteners 17 as described herein, various battery packs 2 of different specifications can be manufactured using the same tray 10.

[0124] Figure 14 This is a schematic perspective view of the main parts of a support fixing moving device according to an embodiment of the present disclosure.

[0125] Reference Figure 1 and Figure 14 The supporting and fixing moving device 30 may include a fastening device 31, a clamping device 32, a moving device 33, a detection device 34, and a control device 35.

[0126] The fastening device 31 can fasten the support fixing member 17 to the mounting base 13 of the plate 11 or loosen the support fixing member 17 from the mounting base 13 of the plate 11 by rotating the support fixing member. The fastening device 31 may include a nut wrench. The fastening device 31 can output a rotational force in a positive or negative direction while contacting and engaging with the rotation holding part 174 formed on the upper part of the support fixing member 17.

[0127] Reference Figure 1 , Figure 4 and Figure 14 The fastening device 31 may include a first support 311, a first actuator 312, and a socket 313.

[0128] The first support member 311 is a device assembly in which the fastening device 31 is configured to support the first actuator 312 and the socket 313. The first support member 311 can be mounted on the third moving body 334 (described herein) of the moving device 33 to be movable vertically. The first support member 311 is mounted on the third moving body 334 in a movable manner not limited to a particular structure or shape, including known techniques such as linear guides that produce linear displacement, and therefore, their detailed description is omitted.

[0129] The first actuator 312 can be fixedly mounted on the first support 311 and can output forward and reverse rotational forces. The first actuator 312 may include a servo motor. The first actuator 312 can be mounted to extend vertically and may have a lower portion where an output shaft (not shown) can be provided. The first support 311 may have a plate, block, or rod shape and may be configured to extend vertically in a manner capable of supporting the first actuator 312 and the socket 313.

[0130] The socket 313 is a device assembly of the fastening device 31 that transmits the rotational force of the first actuator 312 to the support fixture 17. The socket 313 can be connected to the output shaft of the first actuator 312. The socket 313 can engage with the rotation holding portion 174 of the support fixture 17 when the fastening device 31 is lowered. A groove (not shown) with a downward opening having a size and cross-sectional shape corresponding to the rotation holding portion 174 can be formed in the socket 313.

[0131] When the rotation retainer 174 has a polygonal cross-sectional shape, the groove of the socket 313 can have a corresponding polygonal cross-sectional shape. Since the inner surfaces of each of the rotation retainer 174 and the socket 313 have cross-sectional shapes other than circular cross-sectional shapes, the rotational force output from the first actuator 312 can be transmitted to the support fixture 17 without loss through the rotation retainer 174.

[0132] When the first support member 311 descends, the first actuator 312 and the socket 313 also descend with the same displacement as the first support member 311, allowing the socket 313 to engage with the rotation holding portion 174 of the support fixing member 17. At this time, the rotation holding portion 174 can insert into and engage with the groove formed in the socket 313. When the first actuator 312 rotates in the forward direction, the socket 313 can rotate in the forward direction, and the rotational force of the socket 313 is transmitted to the support fixing member 17, thereby allowing the support fixing member 17 to rotate in the forward direction. When rotating in the forward direction, the support fixing member 17 can be screwed onto the mounting base 13.

[0133] When the first actuator 312 operates in the reverse direction, the socket 313 can rotate in the reverse direction, and the rotational force of the socket 313 is transmitted to the support fixture 17, thereby allowing the support fixture 17 to rotate in the reverse direction. The support fixture 17 rotates in the reverse direction to release the threaded fastening to the mounting base 13 and can be separated from the mounting base 13.

[0134] The clamping device 32 can clamp or release the support fixing member 17. The support fixing member 17 can be clamped by the clamping device 32 after being released from the mounting base 13 by the fastening device 31, and can be moved to a desired setting position while being clamped by the clamping device 32. In addition, the support fixing member 17 can be released by the clamping device 32 after reaching the desired setting position.

[0135] Reference Figure 1 , Figure 4 and Figure 14 The clamping device 32 may include a second support 321, a second actuator 322, a guide block 323, a first clamp 324, and a second clamp 328.

[0136] The second support member 321 is a device assembly that forms a support frame for the clamping device 32, supporting the second actuator 322, the guide block 323, the first clamp 324, and the second clamp 328. The second support member 321 can be mounted on the moving device 33. The second support member 321 can be mounted on the moving device 33 via the first support member 311.

[0137] The second support member 321 can be fixedly mounted on the first support member 311. By fixing the second support member 321 on the first support member 311, the first support member 311 and the second support member 321 can move together with the same displacement. The first support member 311 and the second support member 321 can move together with the same displacement when the third moving body 334 moves.

[0138] The fact that the first support member 311 and the second support member 321 move vertically together with the same displacement means that the fastening device 31 and the clamping device 32 move together with the same displacement. By fixing the second support member 321 to the first support member 311, the fastening device 31 and the clamping device 32 can move together with the same displacement. Therefore, the socket 313, the first clamp 324, and the second clamp 328 can always maintain the same relative position and distance.

[0139] The second support 321 may have a block shape and may be positioned below the first actuator 312 to extend horizontally across the socket 313. A hole through which the socket 313 can pass may be formed in the second support 321, and the socket 313 may extend downward from the second support 321 by passing through the hole. A gap is provided between the edge of the hole in the second support 321 and the socket 313 to ensure that the second support 321 does not interfere with the rotation of the socket 313.

[0140] As the extension length of each of the first clamp 324 and the second clamp 328 decreases, the clamping force acting on the first clamp 324 and the second clamp 328 can be transmitted more stably to the gripping and holding portion 175 of the support fixture 17. By positioning the second support member 321 in a position corresponding to the socket 313 as described herein, the guide block 323 on which the first clamp 324 and the second clamp 328 are mounted can be positioned closer to the lower part of the socket 313, and this arrangement can further reduce the extension length of each of the first clamp 324 and the second clamp 328 from the guide block 323 to the gripping and holding portion 175 of the support fixture 17.

[0141] A second actuator 322, having a block shape, can contact and be fixedly mounted on the side surface of the second support 321, and can output hydraulic or pneumatic pressure. The second actuator 322 may include a pneumatic cylinder. The second actuator 322 can output pressing force to move the first clamp 324 and the second clamp 328 closer to or further away from each other.

[0142] The guide block 323 may be a device assembly on which the first clamp 324 and the second clamp 328 are mounted, and may have a block shape and be mounted on the second support 321. The guide block 323 may be mounted on the second support 321 via the second actuator 322. The guide block 323 may contact and be fixedly mounted on the bottom surface of the second actuator 322.

[0143] The guide block 323 may movably support the first clamp 324 and the second clamp 328. The guide block 323 may have a track (not shown) formed to guide the linear movement of the first clamp 324 and the second clamp 328, and at least one of the first clamp 324 and the second clamp 328 may be mounted to be movable along the track.

[0144] The first clamp 324 and the second clamp 328 can be mounted on the guide block 323 and can be positioned facing each other, with the socket 313 located between the first clamp 324 and the second clamp 328. The distance between the first clamp 324 and the second clamp 328 can be varied by the operation of the second actuator 322.

[0145] An elastic member (not shown) can be mounted on the guide block 323, which elastically presses the first clamp 324 and the second clamp 328 in a direction away from each other. At least one of the first clamp 324 and the second clamp 328 can be installed while being elastically pressed by the elastic member.

[0146] When the second actuator 322 is operated (activated), hydraulic or pneumatic pressure acts on at least one of the guide block 323, the first clamp 324, and the second clamp 328, and at least one of the first clamp 324 and the second clamp 328 can move in a direction closer to the other. As a result of this operation, the first clamp 324 and the second clamp 328 can reduce the distance between them to clamp the support fixture 17 together.

[0147] When the second actuator 322 is not operated (off), hydraulic or pneumatic pressure is not applied to each of the guide block 323, the first clamp 324, and the second clamp 328, and at least one of the first clamp 324 and the second clamp 328 can move away from the other due to the elastic restoring force of the elastic member. As a result of this operation, the distance between the first clamp 324 and the second clamp 328 can increase to release the support fixing member 17.

[0148] The first clamp 324 may include a block connection portion 325, an extension portion 326, and a gripping finger 327.

[0149] The block connector 325 is a device assembly forming the upper part of the first clamp 324 and can be movably mounted on the guide block 323. The block connector 325 can be mounted to reciprocate in a direction toward or away from the second clamp 328.

[0150] The extension 326 is a device assembly that forms the middle portion of the first clamp 324 and can extend downward from the block connection 325 to the lower side of the socket 313. The extension 326 may include a horizontally extending first extension 3261 and a vertically extending second extension 3262.

[0151] The first extension 3261 is a device assembly forming the upper part of the extension 326, and can extend rearward from the block connecting portion 325 positioned in front of the socket 313 toward the socket 313. The rear end of the first extension 3261 can be positioned on the left or right side of the socket 313. The second extension 3262 is a device assembly forming the lower part of the extension 326, and can extend downward parallel to the socket 313 from the rear end of the first extension 3261. The lower part of the second extension 3262 can be positioned below the socket 313.

[0152] Thus, the extension 326 can have an "L" shape, extending horizontally at the top and vertically at the bottom. Therefore, the lower part of the extension 326 can be positioned as close as possible to the socket 313 and can extend downwards parallel to the socket 313. Therefore, when the fastening device 31 and the clamping device 32 are lowered together to perform the process of engaging the lower part of the socket 313 with the support member 17, even when the support members 17 are positioned close to each other, the extension 326 can be prevented from interfering with the adjacent support member 17.

[0153] The gripping finger 327 is a device assembly forming the lower part of the first clamp 324, and may have a shape that allows it to contact at least a portion of the outer periphery of the support member 17 and connect to the lower part of the extension 326. The gripping finger 327 may be disposed below the insertion port 313 and positioned facing the gripping retaining portion 175 of the support member 17, while the lower part of the insertion port 313 engages with the rotation retaining portion 174 of the support member 17. The portion of the gripping finger 327 facing the gripping retaining portion 175 may have an arcuate shape corresponding to a portion of the outer periphery of the gripping retaining portion 175.

[0154] A locking step 176 can be formed between the rotation holding portion 174 and the gripping holding portion 175 of the support fixing member 17. When the gripping finger 327 is holding the gripping holding portion 175, the upper part of the gripping finger 327 can be engaged with the locking step 176. When the gripping finger 327 is in contact with the gripping holding portion 175 to hold the support fixing member 17, the locking step 176 can be positioned on the upper part of the gripping finger 327. Therefore, the support fixing member 17 can be restricted and prevented from sliding downwards or separating from the gripping finger 327 while being held and moved by the gripping finger 327.

[0155] Similar to the first clamp 324, the second clamp 328 may include a block connecting portion 325, an extension portion 326, and gripping fingers 327, and may have a structure symmetrical to that of the first clamp 324 relative to the insertion port 313. The second clamp 328 has a structure that is symmetrical and corresponding to that of the first clamp 324, and a detailed description of the structure and operation of the second clamp 328 will be replaced by a description of the first clamp 324.

[0156] The moving device 33 can move the support fixing member 17 held by the clamping device 32 to a first predetermined position sp1 or a second predetermined position sp2 on the tray 10. The moving device 33 may have a structure that enables the fastening device 31 and the clamping device 32 to move upward in a first direction, a second direction, and a third direction that are orthogonal to each other. The first direction may be a left-right direction, the second direction may be a front-back direction, and the third direction may be a vertical direction.

[0157] Reference Figure 1 and Figure 14 The moving device 33 may include a guide rod 331, a first moving body 332, a second moving body 333, and a third moving body 334.

[0158] The guide rod 331 can be configured to extend in a first direction. The guide rod 331 can be positioned above the tray 10, can be rod-shaped, and can be configured as a pair parallel to each other. The pair of guide rods 331 can be configured to extend in a left-right direction. One of the pair of guide rods 331 can be configured to extend in a left-right direction at the front of the tray 10. The other of the pair of guide rods 331 can be configured to extend in a left-right direction at the rear of the tray 10.

[0159] The first movable body 332 may be formed to extend in a second direction and may be mounted on the guide rod 331 to be movable in a first direction. The first movable body 332 may have a rod shape that extends integrally in a front-rear direction and may have front and rear ends respectively movably connected to a pair of guide rods 331. The movable mounting of the first movable body 332 on the guide rods 331 is not limited to a particular structure or shape, and includes known techniques such as linear guides that produce linear displacement; therefore, a detailed description thereof is omitted.

[0160] The second movable body 333 may be formed to extend upward in a third direction and may be mounted on the first movable body 332 to be movable in a second direction. The second movable body 333 may have a rod shape that extends integrally in the vertical direction and may be connected to the first movable body 332 to be movable vertically. The movable mounting of the second movable body 333 on the first movable body 332 is not limited to a specific structure or shape, and includes known techniques such as linear guides that produce linear displacement; therefore, a detailed description thereof is omitted.

[0161] The third movable body 334 is a device assembly that forms a support frame configured to support the fastening device 31, the clamping device 32, and the detection device 34. The third movable body 334 can be mounted on the second movable body 333 to be able to move up and down in a third direction. The fastening device 31, the clamping device 32, and the detection device 34 can be movably mounted on the third movable body 334.

[0162] The third moving body 334 may include a lifting body 335, a first track 336, and a second track 337.

[0163] The lifting body 335 is a device assembly that forms the basic framework of the third moving body 334, and can be mounted on the second moving body 333 to move vertically up and down in a third direction. The first track 336 is a device assembly that guides the vertical movement of the detection device 34, and can be configured to extend vertically along one side of the lifting body 335. The second track 337 is a device assembly that guides the vertical movement of the fastening device 31 and the clamping device 32, and can be configured to extend vertically along the other side of the lifting body 335. The second track 337 can be arranged parallel to the first track 336 with a gap between them.

[0164] The detection device 34 can be mounted on the first track 336 to be movable vertically. The fastening device 31 and the clamping device 32 can be mounted together on the second track 337 to be movable vertically. The fastening device 31 may include a first support member 311 movably mounted on the first track 336, and the clamping device 32 may include a second support member 321 mounted on the first support member 311. By mounting the first support member 311 on the second track 337 to be movable vertically, the fastening device 31 and the clamping device 32 can also be mounted together on the second track 337 to be movable vertically. As described herein, the detection device 34 and the first support member 311 can be manufactured separately and mounted on the first track 336 and the second track 337 respectively to be movable vertically.

[0165] Therefore, even when an impact force acts on the detection device 34 due to contact or collision with the support fixing member 17, the impact force can be absorbed at the connection between the detection device 34 and the first track 336, thereby preventing the impact force from being transmitted to the lifting body 335 and the first support member 311. A buffer member (not shown) capable of absorbing the impact force can be provided at the connection between the detection device 34 and the first track 336.

[0166] Furthermore, even when an impact force acts on the fastening device 31 or clamping device 32 due to contact or collision with the support fixing member 17, the impact force can be absorbed at the connection between the first support member 311 and the second track 337, thereby preventing the impact force from being transmitted to the lifting body 335 and the detection device 34. A buffer member (not shown) capable of absorbing the impact force can be provided at the connection between the first support member 311 and the second track 337.

[0167] The installation of the first movable body 332, the second movable body 333, and the third movable body 334, which are capable of moving along the track, is not limited to a specific structure or shape, and includes known techniques such as linear guides that produce linear displacement; therefore, a detailed description thereof is omitted. Furthermore, although the track is shown in a recessed form in the accompanying drawings of this disclosure, this is merely an example illustrating a specific example of the track and is not limiting. The track of this disclosure is not limited to a specific structure and shape, and includes recessed forms, protruding forms, linear rod forms, etc.

[0168] The detection device 34 is a device assembly for detecting the position of the support fastener 17 mounted on the tray 10. The detection device 34 can be positioned at a predetermined distance d2 from the fastening device 31 and the clamping device 32 in the front-rear direction. Contact sensors or non-contact sensors can be selectively applied to the detection device 34. As an example, a contact sensor that directly contacts the support fastener 17 can be applied to the detection device 34.

[0169] By employing a contact sensor as the detection device 34, when the detection device 34 is lowered, its lower part directly contacts the support fixture 17, thereby minimizing detection errors or malfunctions. The detection device 34 is not limited to a specific structure or shape, as long as it can detect the position of the support fixture 17; it includes known technologies such as vision cameras. Therefore, a detailed description of its structure and operation is omitted.

[0170] Figure 15 This is a flowchart illustrating the process of moving a support fastener from a first predetermined position to a second predetermined position using a support fastener moving device according to an embodiment of the present disclosure. Figures 16 to 21 This is a conceptual diagram illustrating the process of moving a support fastener from a first predetermined position to a second predetermined position using a support fastener moving device according to an embodiment of the present disclosure.

[0171] The control device 35 can control the operation of the fastening device 31, the clamping device 32, and the moving device 33. The control device 35 can control the operation of the fastening device 31, the clamping device 32, and the moving device 33 based on pre-inputted information about the battery pack 2 or input commands. The control device 35 can receive information or commands regarding which of the first battery pack 2A, the second battery pack 2B, and the third battery pack 2C is being manufactured, and can control the operation of the fastening device 31, the clamping device 32, and the moving device 33, such that the support fixing member 17 is configured to correspond to the one of the first battery pack 2A, the second battery pack 2B, and the third battery pack 2C being manufactured.

[0172] Furthermore, the control device 35 can determine the position of the support fixture 17 based on the detection information from the detection device 34, and can control the operation of the fastening device 31, the clamping device 32, and the moving device 33. (See reference...) Figure 15 When the control device 35 detects through the detection device 34 that the support fixing member 17 is positioned at the first set position sp1, the control device 35 can control the fastening device 31, the clamping device 32 and the moving device 33 to loosen the support fixing member 17 at the first set position sp1, move the support fixing member 17 to the second set position sp2, and fasten the support fixing member 17 at the second set position sp2.

[0173] The control device 35 can control the operation of the fastening device 31, the clamping device 32 and the moving device 33 to sequentially perform the following processes: using the detection device 34 to detect the support fastener 17 at the first set position sp1; using the fastening device 31 to loosen the support fastener 17; using the clamping device 32 to clamp the support fastener 17 to separate the support fastener 17 from the plate 11; and moving the support fastener 17 to the second set position sp2 to fasten the support fastener 17 to the plate 11.

[0174] The process of using the detection device 34 to detect the support fixture 17 on the first set position sp1 can be performed sequentially by the first moving operation (S1), the first lowering operation (S2), the support fixture detection operation (S3), and the first raising operation (S4).

[0175] In the first movement operation (S1), as Figure 14 As shown, the detection device 34 can be positioned at the first set position sp1. At this time, the detection device 34 and the clamping device 32 can be positioned at the first height h1. In the first descent operation (S2), as... Figure 16 As shown, the detection device 34 descends along the first track 336 to be positioned below the clamping device 32, and as... Figure 17 As shown, the third moving body 334 can descend while the detection device 34 remains positioned below the clamping device 32.

[0176] As the detection device 34 descends along the first track 336, it can be positioned at a second height h2. As described herein, by further descending the third moving body 334 while maintaining its position below the clamping device 32, the detection device 34 can descend to a third height h3. At this point, the detection device 34 can have a descent displacement equal to the sum of the distance the third moving body 334 descended and the distance the detection device 34 descended along the first track 336. The detection device 34 can descend from the first height h1 to the third height h3 via a multi-stage descent process as described herein.

[0177] By connecting the detection device 34 to the third moving body 334 via the first track 336 in a manner that allows vertical movement, compared to an embodiment where the detection device 34 is integrally fixed and connected to the third moving body 334, the guide rod 331 can be positioned at a lower height from the ground. This arrangement reduces the overall vertical (height-down) height of the battery pack assembly unit 1 according to this disclosure. Therefore, the process can be easily inspected visually by workers, facilitating easier maintenance and management, and allowing impact forces acting on the detection device 34 to be absorbed at the connection with the first track 336.

[0178] The detection device 34, which has descended to the third height h3, can contact the support fixing member 17 positioned at the first set position sp1. During the support fixing member detection operation (S3), as... Figure 17 As shown, the detection device 34 is brought into contact with the support fixing member 17 to detect that the support fixing member 17 is positioned at the first set position sp1. In the first lifting operation (S4), the detection device 34 can rise along the first track 336, and the third moving body 334 can rise along the second moving body 333 to return the detection device 34 to the first height h1. At this time, the movement of the detection device 34 and the movement of the third moving body 334 can be performed sequentially, in reverse order, or simultaneously.

[0179] The processes of loosening the support fastener 17 using the fastening device 31, clamping the support fastener 17 using the clamping device 32, and separating the support fastener 17 from the plate 11 can be performed sequentially by the device exchange operation (S5), the second descent operation (S6), the loosening operation (S7), the clamping operation (S8), and the second descent operation (S9).

[0180] In the device exchange operation (S5), the fastening device 31 and the clamping device 32 can be moved backward by a predetermined distance d2 to be positioned at the first predetermined position sp1. The device exchange operation (S5) can be performed by moving the second moving body 333 backward along the first moving body 332 by a predetermined distance d2. When the second moving body 333 is moved backward by a predetermined distance d2, the fastening device 31, the clamping device 32, and the detection device 34 can all be moved backward by a predetermined distance d2. In the state where the device exchange operation (S5) is completed, the clamping device 32 can be positioned at the first height h1.

[0181] In the second descent operation (S6), as Figure 18 As shown, the fastening device 31 and the clamping device 32 can descend along the second track 337 to be positioned below the detection device 34, and as... Figure 19 As shown, with the fastening device 31 and the clamping device 32 positioned below the detection device 34, the third moving body 334 can be further lowered.

[0182] By lowering the first support member 311 along the second track 337, the fastening device 31 and the clamping device 32 can be lowered along the second track 337. With the fastening device 31 and the clamping device 32 lowered along the second track 337, they can be positioned at a second height h2. By further lowering the third moving body 334 while the fastening device 31 and the clamping device 32 are positioned below the detection device 34, as described herein, the fastening device 31 and the clamping device 32 can be lowered to a third height h3. At this point, the fastening device 31 and the clamping device 32 can have a lowering displacement equal to the sum of the distance the fastening device 31 and the clamping device 32 have descended along the second track 337 and the distance the third moving body 334 has descended. The fastening device 31 and the clamping device 32 can be lowered from a first height h1 to a third height h3 via a multi-stage lowering process as described herein.

[0183] By connecting the fastening device 31 and the clamping device 32 to the third moving body 334 via the second rail 337 in a manner allowing vertical movement, as described herein, the guide rod 331 can be positioned at a lower height from the ground compared to an embodiment where the fastening device 31 and the clamping device 32 are integrally fixed and connected to the third moving body 334. This arrangement reduces the overall vertical (height-down) height of the battery pack assembly unit 1 according to this disclosure. Therefore, the process can be easily inspected visually by the operator, facilitating easier maintenance and management, and allowing impact forces acting on the fastening device 31 and the clamping device 32 to be absorbed at the connection with the second rail 337.

[0184] The fastening device 31, which has descended to the third height h3, can contact the support fixing member 17 positioned at the first set position sp1. During the release operation (S7), as... Figure 19 As shown, the fastening device 31 can be brought into contact with the support fixing member 17, and the fastening device 31 can be used to apply a reverse rotational force to the support fixing member 17 to release the support fixing member 17 from the mounting base 13 located at the first set position sp1. In the clamping operation (S8), the clamping device 32 can be used to clamp the support fixing member 17.

[0185] In the second ascent operation (S9), as Figure 20 As shown, the first support 311 can rise along the second track 337, and the third moving body 334 can rise along the second moving body 333 to return the clamping device 32 to the first height h1. At this time, the movement of the first support 311 and the movement of the third moving body 334 can occur sequentially, in reverse order, or simultaneously.

[0186] The process of moving the support fastener 17 to the second set position sp2 and fastening the support fastener 17 to the plate 11 can be performed sequentially by the second moving operation (S10), the third lowering operation (S11), the releasing operation (S12), and the fastening operation (S13).

[0187] In the second movement operation (S10), the support fixing member 17 can be moved to the second set position sp2. The second set position sp2 can be positioned in front of the first set position sp1. By moving the second moving body 333 forward along the first moving body 332, the support fixing member 17 can move from the first set position sp1 to the second set position sp2. When the second moving body 333 moves forward, the fastening device 31, the clamping device 32, and the detection device 34 can also move forward together. In the state after the second movement operation (S10) is completed, the clamping device 32 can be positioned at the first height h1.

[0188] In the third descent operation (S11), the fastening device 31 and the clamping device 32 can descend along the second track 337 to be positioned below the detection device 34, and as... Figure 21 As shown, the third moving body 334 can be further lowered while the fastening device 31 and the clamping device 32 are positioned below the detection device 34.

[0189] By lowering the first support member 311 along the second track 337, the fastening device 31 and the clamping device 32 can also descend along the second track 337. As the fastening device 31 and the clamping device 32 descend along the second track 337, they can be positioned at a second height h2. By further lowering the third moving body 334, as described herein, with the fastening device 31 and the clamping device 32 positioned below the detection device 34, the fastening device 31 and the clamping device 32 can descend to a third height h3.

[0190] At this point, the fastening device 31 and the clamping device 32 can have a downward displacement equal to the sum of the distance the fastening device 31 and the clamping device 32 descend along the second track 337 and the distance the third moving body 334 descends. The movement of the first support 311 and the movement of the third moving body 334 can occur sequentially, in reverse order, or simultaneously. The fastening device 31 and the clamping device 32 can descend from the first height h1 to the third height h3 via a multi-stage descent process as described herein.

[0191] When the fastening device 31 and the clamping device 32 descend to the third height h3, the support fixing member 17 can contact the mounting base 13 positioned at the second set position sp2 and be placed on the mounting base 13. In the release operation (S12), the support fixing member 17 can be released using the clamping device 32. In the fastening operation (S13), as... Figure 21 As shown, when the support fastener 17 is placed on the mounting base 13, the fastening device 31 can be used to apply a positive rotational force to the support fastener 17 to fasten the support fastener 17 to the mounting base 13 located at the second set position sp2.

[0192] By repeatedly performing the control process on multiple support fasteners 17, the position of the support fasteners 17 can be changed and adjusted according to the model of the battery pack 2 to be manufactured.

[0193] According to embodiments of this disclosure, a support fixing device can be used to automatically adjust the position of a support fixing mounted on a tray to match the model of the battery pack to be manufactured. Therefore, different models of battery packs can be manufactured on a single battery pack production line corresponding to an extended path of the conveyor, while further reducing the process defect rate, shortening working time, and preventing safety accidents caused by support fixing falling during manual operation compared to when the position of the support fixing is manually changed by an operator.

[0194] Furthermore, according to embodiments of this disclosure, the fastening device of the support fixing device can be used to fasten the support fixing member to or release it from the mounting base, a clamping device can be used to hold or release the support fixing member, and the moving device can be used to move the fastening device, clamping device, and support fixing member to the desired position. Therefore, based on the model of the battery pack to be produced, the support fixing member can be automatically removed and assembled in the desired position using the support fixing device.

[0195] However, the effects that can be obtained through this disclosure are not limited to those described herein, and those skilled in the art will clearly understand other technical effects not mentioned in the accompanying description.

[0196] Although this disclosure has been described with reference to embodiments shown in the accompanying drawings, these embodiments are merely illustrative, and it should be understood that those skilled in the art can derive various modifications and equivalent other embodiments based on the embodiments.
