[0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2025-0008503 filed on January 21, 2025, and all contents disclosed in the document of said Korean patent application are incorporated herein as part of this specification.

[0003] The present invention relates to a battery module manufacturing device, and more specifically, to a battery module manufacturing device capable of improving sagging that occurs in the central part of an upper plate during the assembly process of a module frame.

[0004] In modern society, as the use of portable devices such as mobile phones, laptops, camcorders, and digital cameras, as well as energy storage systems (ESS), has become commonplace, the development of technologies in related fields is becoming active. Furthermore, rechargeable secondary batteries are being utilized as power sources for electric vehicles (EVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (P-HEVs) as a solution to address air pollution caused by conventional gasoline vehicles using fossil fuels; consequently, the need for the development of secondary batteries is increasing.

[0005] Currently commercialized rechargeable batteries include nickel-cadmium, nickel-hydrogen, nickel-zinc, and lithium-ion batteries. Among these, lithium-ion batteries are receiving the most attention due to their advantages of free charging and discharging, low self-discharge rate, and high energy density.

[0006] While small mobile devices use one or two or three battery cells per device, medium-to-large devices such as automobiles require high output and large capacity. Therefore, medium-to-large battery modules in which multiple battery cells are electrically connected are used.

[0007] Since it is desirable for medium-to-large battery modules to be manufactured with the smallest possible size and weight, prismatic batteries and pouch-type batteries, which can be stacked with high integration density and have a low weight-to-capacity ratio, are mainly used as battery cells for medium-to-large battery modules. Meanwhile, the battery module may include a frame member that houses the battery cell stack in an internal space, with the front and rear sides open, to protect the cell stack from external shock, heat, or vibration.

[0008] Figure 1 is a drawing illustrating a case where sagging occurs on the upper plate of a battery module when manufactured by a conventional battery module manufacturing device.

[0009] Referring to FIG. 1, the module frame (10) of a battery module may include a lower frame (11) and an upper plate (12). The module frame (10) is formed such that the upper plate (12) is assembled on the lower frame (11). In the case of a conventional battery module manufacturing device, the upper plate (12) is pressed in the direction of the lower frame (11) during the process of assembling the upper plate (12) to the lower frame (11). As the upper plate (12) is simply pressed in the direction where the lower frame (11) is located, deformation occurs in the upper plate (12) in the direction toward the lower frame (11). Consequently, there is a problem of sagging occurring in the central part of the upper plate (12). Accordingly, there is a problem of deterioration in the appearance of the module frame (10) assembled by the conventional battery module manufacturing device.

[0010] The problem that the present invention aims to solve is to provide a battery module manufacturing device capable of improving the sagging that occurs in the central part of the upper plate during the assembly process of the module frame.

[0011] However, the problems that the embodiments of the present invention aim to solve are not limited to the problems described above and can be expanded in various ways within the scope of the technical ideas included in the present invention.

[0012] A battery module manufacturing device according to one embodiment of the present invention includes a pressurizing part that presses an upper plate covering the upper surface of a battery module and an actuator connected to the pressurizing part to move the pressurizing part in an up-and-down direction, and the pressurizing part can form negative pressure at a contact surface in contact with the upper plate while pressing the upper plate.

[0013] The above-mentioned pressurizing member includes a plurality of pressurizing members spaced apart at a predetermined interval along the longitudinal direction of the upper plate and an adsorption opening formed in the pressurizing members, and a negative pressure can be formed at the contact surface with the upper plate through the adsorption opening.

[0014] The above adsorption openings are formed in plurality in the pressurizing member, and the plurality of adsorption openings may be spaced apart along the length direction.

[0015] The above-mentioned pressure member may further include a connecting member that supports the plurality of pressure members arranged along the length direction.

[0016] The above-mentioned pressurizing member may further include an adsorption passage communicating with the adsorption opening and a connecting passage formed inside the connecting member and communicating with the adsorption passage.

[0017] The above battery module manufacturing device may further include a pump unit that communicates with the above connecting passage and forms negative pressure on the contact surface of the pressurizing unit and the upper plate.

[0018] The above connecting members are provided in plurality, and the plurality of connecting members may be spaced apart in a width direction perpendicular to the length direction of the upper plate.

[0019] The plurality of connecting members may be arranged so that the plurality of pressing members press both ends of the upper plate in the width direction.

[0020] The plurality of connecting members may be arranged so that the plurality of pressing members are spaced apart from both ends of the upper plate by a predetermined distance and pressurize.

[0021] The plurality of connecting members may be arranged so that the plurality of pressing members are spaced at least 1 mm apart from both ends of the upper plate and pressurize.

[0022] The above battery module manufacturing device may further include a second pressing member positioned to press both ends of the upper plate in the longitudinal direction.

[0023] The above battery module manufacturing device may further include a retaining member that forms negative pressure at the center of the upper plate based on the width direction of the upper plate.

[0024] The above-mentioned retaining member can form negative pressure at the center of the upper plate based on the length direction.

[0025] When the above-mentioned pressurizing part presses the upper plate, the above-mentioned retaining part may not press the upper plate while in contact with the upper plate.

[0026] The above-mentioned pressure member may further include a pad member having elasticity, which is attached to the pressure member to contact the upper plate.

[0027] The above battery module manufacturing device may further include a clamp member that supports at least a portion of a lower frame covering the lower part and both sides of the battery module.

[0028] The battery module manufacturing device according to the embodiments of the present invention can improve sagging occurring in the central part of the upper plate because the pressing member presses the upper plate while simultaneously adsorbing the upper plate. Accordingly, the degradation of appearance quality occurring on the module frame during the assembly process of the battery module can be improved.

[0029] The effects of the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims.

[0036] Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. The present invention may be embodied in various different forms and is not limited to the embodiments described herein.

[0037] To clearly explain the present invention, parts unrelated to the explanation have been omitted, and the same reference numerals are used for identical or similar components throughout the specification.

[0038] Furthermore, the size and thickness of each component shown in the drawings are depicted arbitrarily for convenience of explanation, and thus the present invention is not necessarily limited to what is illustrated.

Additionally, for convenience of explanation, the thickness of some layers and regions has been exaggerated in the drawings.

[0039] Furthermore, when a part such as a layer, membrane, region, or plate is said to be "on" or "on" another part, this includes not only the case where it is "directly above" the other part, but also the case where there is another part in between. Conversely, when a part is said to be "directly above" another part, it means that there is no other part in between. Also, saying that a part is "on" or "on" a reference part means that it is located above or below the reference part, and does not necessarily mean that it is located "on" or "on" facing the opposite direction of gravity.

[0040] In addition, terms indicating directions such as front, back, left, right, up, and down have been used; however, these terms are merely for the convenience of explanation and may vary depending on the location of the object or the observer.

[0041] Furthermore, throughout the specification, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0042] Additionally, throughout the specification, "planar" means when the subject part is viewed from above, and "cross-sectional" means when the cross-section obtained by vertically cutting the subject part is viewed from the side.

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] FIG. 2 is a schematic diagram for explaining a battery module manufacturing apparatus according to an embodiment of the present invention. FIG. 3 is a longitudinal cross-sectional view of the pressurizing part shown in FIG. 2. FIG. 4 to 6 are cross-sectional views in the width direction of the pressurizing part shown in FIG. 2, and are drawings for explaining the assembly process of the upper plate.

[0045] Referring to FIGS. 2 to 6, a battery module manufacturing device (100) according to one embodiment of the present invention may include a pressurizing part (110) that pressurizes an upper plate (12) covering the upper surface of a battery module, a pump part (130) that forms negative pressure on the contact surface between the pressurizing part (110) and the upper plate (12), an actuator (140) connected to the pressurizing part (110) to move the pressurizing part (110) in an up-and-down direction, and a clamp member (120) that supports at least a part of a lower frame covering the lower part and both sides of the battery module.

[0046] First, the battery module includes a plurality of battery cells. For example, the battery module may include a battery cell stack in which a plurality of battery cells are stacked. For example, battery cells may be stacked along one direction to form a battery cell stack. Such a battery cell stack may be housed in the internal space formed by the module frame (10) and the end plate.

[0047] The module frame (10) can accommodate a battery cell stack. The module frame (10) may include a lower frame (11) and an upper plate (12).

[0048] The lower frame (11) may include a bottom plate and two side plates extending upward from both ends of the bottom plate. The bottom plate may cover the bottom (-z-axis direction) of the battery cell stack, and the side plates may cover both sides (y-axis direction and -y-axis direction) of the battery cell stack.

[0049] The upper plate (12) may be a member that covers the upper part of the battery cell stack. For example, the upper plate (12) may be a plate-shaped member that covers the upper part of the battery cell stack. The upper plate (12) may be a plate-shaped member that covers the upper part (z-axis direction) of the battery cell stack, excluding the lower part and both side parts that are wrapped by the lower frame (11).

[0050] The upper plate (12) and the lower frame (11) can be joined by welding or the like while their corresponding corner portions are in contact with each other, thereby forming a structure that covers the battery cell stack in all directions (up, down, left, and right). That is, the module frame (10) may be a box-shaped member with the facing front and rear sides open. Accordingly, the module frame (10) can physically protect the battery cell stack through the upper plate (12) and the lower frame (11). To this end, the upper plate (12) and the lower frame (11) may include a metal material having a certain strength.

[0051] The end plate may be a member joined to the module frame (10) while covering the open front and rear of the module frame (10). There are no special restrictions on the method of joining between the module frame (10) and the end plate, but for example, welding may be performed on the mutually facing sides of the module frame (10) and the end plate.

[0052] A battery module manufacturing device (100) according to one embodiment of the present invention can be used to attach an upper plate (12) to a lower frame (11) of a module frame (10). For example, in order to weld and attach an upper plate (12) to a lower frame (11), the upper plate (12) needs to be in close contact with the lower frame (11). To this end, the battery module manufacturing device (100) can press the upper plate (12) toward the lower frame (11). More specifically, the battery module manufacturing device (100) can press the upper plate (12) in a downward direction (-z-axis direction) to bring both ends of the upper plate (12) in the width direction (y-axis direction and -y-axis direction) into close contact with both side plates of the lower frame (11).

[0053] The pressurizing part (110) can pressurize the upper plate (12) and form negative pressure at the contact surface in contact with the upper plate (12).

[0054] Specifically, the pressure member (110) may include a plurality of pressure members (111) spaced apart at a predetermined interval along the longitudinal direction of the upper plate (12), a pad member (112) attached to the pressure members (111) to contact the upper plate (12), an adsorption opening (113) formed in the pressure members (111), and a connecting member (115) supporting the plurality of pressure members (111).

[0055] The pressing member (111) is a member that presses the upper plate (12). The pressing member (110) can press both ends (longer sides of the upper plate (12)) in the width direction of the upper plate (12). At this time, in order for the pressing member (110) to press the upper plate (12) more uniformly, the pressing member (111) can be formed in a shape that extends along the length direction (x-direction) of the upper plate (12). Since a plurality of pressing members (111) extend along the length direction of the upper plate (12) and are arranged in a row along the length direction, the plurality of pressing members (111) can press both ends in the width direction of the upper plate (12) more uniformly.

[0056] The pad member (112) may be a member that comes into direct contact with the upper plate (12). The pad member (112) may be attached to the surface facing the upper plate (12) where the pressure member (111) is located. The pad member (112) is a member intended to prevent damage to the upper plate (12) during the process in which the pressure member (111) presses the upper plate (12). The pad member (112) may be provided with elasticity so that it can deform when the pressure member (111) presses the upper plate (12). For example, the pad member (112) may be formed of rubber, silicone, etc. However, the material of the pad member (112) is not limited to what is described above and may be modified or changed in various ways depending on the environment in which the present invention is implemented.

[0057] Since the pad member (112) is attached to the lower surface of the pressure member (111), the pad member (112) may have a shape corresponding to the pressure member (111). For example, the shape of the pad member (112) may be a shape corresponding to the lower surface of the pressure member (111). Additionally, an opening corresponding to the adsorption opening (113) formed in the pressure member (111) described later may be formed in the pad member (112) at a corresponding position and shape. That is, for convenience of explanation, the description regarding the pad member (112) may be omitted below, and the content described regarding the pressure member (111) may be applied equally to the pad member (112).

[0058] The adsorption opening (113) is formed in the pressurizing member (111). Specifically, the adsorption opening (113) may be formed on the surface of the pressurizing member (111) facing the upper plate (12). The adsorption opening (113) communicates with the pump unit (130) described later, and depending on the operation of the pump unit (130), negative pressure may be formed at the contact surface with the upper plate (12) through the adsorption opening (113).

[0059] Adsorption openings (113) may be formed in plurality on the pressurizing member (111), and the plurality of adsorption openings (113) may be spaced apart along the longitudinal direction (X-axis direction). For example, as illustrated in the example of FIG. 3, two adsorption openings (113) may be formed spaced apart along the longitudinal direction of the pressurizing member (111). However, the number of adsorption openings (113) formed on the pressurizing member (111) is not limited by the above description and may be varied or changed in various ways depending on the environment in which the present invention is implemented.

[0060] As described above, the pressurizing member (111) extends in the longitudinal direction of the upper plate (12). Therefore, since multiple adsorption openings (113) are formed along the longitudinal direction, uniform adsorption of the upper plate (12) can be achieved through the pressurizing member (110).

[0061] The connecting member (115) can support a plurality of pressure members (111) arranged along the longitudinal direction. To this end, the connecting member (115) can extend in the longitudinal direction (x-direction) of the upper plate (12). Since a plurality of pressure members (111) are connected to the connecting member (115), as the connecting member (115) moves in the vertical direction (z-axis direction and -z-axis direction), the plurality of pressure members (111) can also move in the vertical direction. For example, when the upper plate (12) is pressed toward the lower frame (11), the connecting member (115) can be moved in the downward direction (-z-direction) so that the pressure members (111) can press the upper plate (12) in the downward direction.

[0062] An adsorption passage (114) communicating with an adsorption opening (113) may be formed inside the pressurizing member (111). Additionally, a connecting passage (116) communicating with the adsorption passage (114) may be formed inside the connecting member (115). Accordingly, the adsorption opening (113) formed in each pressurizing member (111) may communicate with the connecting passage (116) through the adsorption passage (114). Furthermore, since the connecting passage (116) may communicate with the pump unit (130) described later, negative pressure may be formed at the contact surface with the upper plate (12) through each adsorption opening (113) depending on the operation of the pump unit (130).

[0063] A plurality of connecting members (115) may be provided. As illustrated in the examples in FIGS. 4 to 6, a plurality of connecting members (115) may be spaced apart in the width direction (y-axis direction) which is orthogonal to the length direction of the upper plate (12). More specifically, a plurality of connecting members (115) may be arranged so that a plurality of pressing members (111) press both ends of the upper plate (12) in the width direction. For example, a plurality of connecting members (115) may be arranged adjacent to both ends of the upper plate (12) in the width direction. Through such arrangement of connecting members (115), a battery module manufacturing device according to one embodiment of the present invention can stably position the upper plate (12) on the lower frame (11).

[0064] A plurality of connecting members (115) may be arranged so that a plurality of pressing members (111) are spaced apart from both ends of the upper plate (12) by a predetermined distance and press. For example, a plurality of connecting members (115) may be arranged so that a plurality of pressing members (111) are spaced apart from both ends of the upper plate (12) by at least 1 mm, preferably at least 2 mm, and press. Because the pressing members (111) are spaced apart from the upper plate (12) by a predetermined distance, the pressing members (111) are not affected by the heat generated during welding of the upper plate (12) and the lower frame (11), and damage caused by welding spatter can be prevented.

[0065] The clamp member (120) may be a member positioned to face the side plate of the lower frame (11). The clamp member (120) may contact or press the side plate of the lower frame (11) to prevent the side plate from moving in the width direction (y-axis direction and -y-axis direction). Accordingly, during the assembly process of the upper plate (12) and the lower frame (11), it is possible to ensure that the upper plate (12) is assembled to the lower frame (11) at the correct position.

[0066] Meanwhile, although not shown in FIG. 2, the battery module manufacturing device (100) may include a jig that supports the bottom plate of the lower frame (11). Since the jig can be commonly used to support the bottom plate of the lower frame (11), a detailed description thereof will be omitted.

[0067] The pump unit (130) can form negative pressure at the contact surface between the pressurizing unit (110) and the upper plate (12). Specifically, the pump unit (130) is in communication with the connecting passage (116) formed in the connecting member (115) and the adsorption passage (114) formed in the pressurizing member (111), and can finally be in communication with the adsorption opening (113). Accordingly, negative pressure can be formed at the contact surface between the pressurizing member (111) and the upper plate (12) depending on the operation of the pump unit (130). As negative pressure is formed at the contact surface between the pressurizing member (111) and the upper plate (12), the pressurizing member (111) can exert an adsorption force on the upper plate (12).

[0068] The actuator (140) can move the pressurizing member (110) in the up and down direction (z-axis direction and -z-axis direction). The actuator (140) can generate a driving force to move the pressurizing member (110), more specifically the connecting member (115), in the up and down direction. Meanwhile, although not shown in FIG. 2, the battery module manufacturing device (100) according to one embodiment of the present invention may be equipped with a power transmission mechanism to convert the driving force generated by the actuator (140) in the up and down direction. However, the power transmission mechanism may be a mechanism commonly used to convert the driving force of the actuator (140), and a detailed description thereof is omitted.

[0069] Meanwhile, FIG. 2 illustrates that a pump unit (130) and an actuator (140) are each connected to a plurality of connecting members (115), but this is merely an exemplary form, and the number and arrangement of the pump unit (130) and the actuator (140) can be varied or changed depending on the environment in which the present invention is implemented. For example, a plurality of connecting members (115) can be connected to each other, and accordingly, one pump unit (130) and one actuator (140) can be connected. In addition, although the pump unit (130) and the actuator (140) are shown attached sequentially to the connecting member (115), only the actuator (140) may be connected to the connecting member (115), and the connecting member (115) and the pump unit (130) may be connected by additional piping.

[0070] Referring to FIGS. 4 to 6, the operation of the pressurizing member (110) is explained as follows: First, the pressurizing member (111) moves downward toward the upper plate (12) (see FIG. 4). When the pressurizing member (111) comes into contact with the upper plate (12), negative pressure is formed on the contact surface between the pressurizing member (111) and the upper plate (12) through the adsorption opening (113) of the pressurizing member (111) (see FIG. 5). With negative pressure formed on the contact surface between the pressurizing member (111) and the upper plate (12), the pressurizing member (111) presses the upper plate (12) downward (see FIG. 6). As shown in the example in FIG. 6, since the pressurizing member (111) presses the upper plate (12) while simultaneously adsorbing the upper plate (12), the sagging occurring in the central part of the upper plate (12) can be improved. Accordingly, a battery module manufacturing device (100) according to one embodiment of the present invention can improve the appearance quality degradation occurring on a module frame (10) during the assembly process of a battery module.

[0071] FIG. 7 is a drawing for explaining the pressurizing part and the holding part of a battery module manufacturing device according to another embodiment of the present invention. FIG. 8 is an exemplary drawing for explaining the force applied to the upper plate by the battery module manufacturing device shown in FIG. 7.

[0072] Referring to FIGS. 7 and 8, the battery module manufacturing device (100) may include a second pressing member (111) positioned to press both ends in the longitudinal direction of the upper plate (12) and a retaining member (160) that forms negative pressure in a part of the upper plate.

[0073] The second pressure member (150) is configured to apply pressure to both ends (short sides of the upper plate (12)) along the longitudinal direction of the upper plate (12). Therefore, the same content as the aforementioned pressure member (110) may be applied. For example, the second pressure member (150) may be equipped with the same pressure member (111), pad member (112), adsorption opening (113), connecting member (115), etc. as the aforementioned pressure member (110). However, since the second pressure member (150) applies pressure to both ends along the longitudinal direction of the upper plate (12), it applies pressure over a shorter length than the aforementioned pressure member (110). Therefore, the shape of the pressure member of the second pressure member (150) may be different from the shape of the pressure member (111) of the aforementioned pressure member (110). For example, the shape of the aforementioned pressure member (111) is a shape that extends along the length direction of the upper plate (12), but the pressure member of the second pressure part (150) extends along the width direction of the upper plate (12), and the ratio of the long side to the short side of the pressure member of the second pressure part (150) may be closer to 1 than the ratio of the long side to the short side of the pressure member (111) of the pressure part (110).

[0074] Meanwhile, although not shown in FIG. 7, the second pressurizing unit (150) may be connected to the aforementioned connecting member (115) through the second connecting member and connected to the aforementioned pump unit (130) and actuator (140). However, the configuration of the second pressurizing unit (150) is not limited to what is described above, and the second pressurizing unit (150) may be connected to a separate pump unit and actuator and operate independently of the pressurizing unit (110).

[0075] The retaining part (160) is configured to form negative pressure in a part of the upper plate. For example, the retaining part (160) can form negative pressure at the center of the upper plate with respect to the width direction of the upper plate (12). Additionally, the retaining part (160) can form negative pressure at the center of the upper plate (12) with respect to the width direction and length direction of the upper plate (12). To this end, although not shown in FIG. 7, the retaining part (160) may have the same configuration as the adsorption opening (113) and connecting member (115) of the aforementioned pressurizing part (110). However, unlike the aforementioned pressurizing part (110), the retaining part (160) does not press the upper plate (12) while in contact with the upper plate (12) when the pressurizing part (110) and the second pressurizing part (150) pressurize the upper plate (12).

[0076] Accordingly, as illustrated in the example in FIG. 8, the upper plate (12) receives a force in the downward direction (-z direction) toward the lower frame (11) as the area (A1) adjacent to both ends in the width direction and the area (A2) adjacent to both ends in the length direction are pressed by the pressing part (110) and the second pressing part (150). At this time, the central area (A3) of the upper plate (12) receives a force in the upward direction (z direction) by the holding part (160). Therefore, sagging occurring in the central part of the upper plate (12) can be more reliably prevented by the holding part (160).

[0077] Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
