Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable readers to better understand this application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in this application can be implemented. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0027] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0028] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A exists, A and B exist simultaneously, and B exists. In addition, the character " / " in this document generally indicates that the related objects before and after it have an "or" relationship.

[0029] In the description of the embodiments of this application, the technical terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0030] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0031] In the accompanying drawings corresponding to the embodiments of this application, the thickness and / or area of ​​layers, films, panels, regions, etc., are enlarged for better understanding and ease of description. Throughout the specification, the same reference numerals denote the same elements. It should be understood that when describing a component (such as a layer, film, region, or substrate) on or on the surface of another component, the component may be "directly" located on the surface of the other component, or there may be an intermediate component between the two components. Conversely, when describing a component on the surface of another component, or a component "directly" on another component, or a component surface on which another component is formed or disposed, it indicates that there is no intermediate component between the two components. Furthermore, when describing a component as "generally" formed on another component, it means that the component is not formed on the entire surface (or front surface) of the other component, nor is it formed on a portion of the edge of the entire surface.

[0032] A battery assembly is formed by encapsulating battery modules within a housing. After molding, the battery modules undergo an assembly process, where they are inserted into the housing. Each battery module contains a large number of cells, which are connected in series or parallel via electrode connection components. The cells are positioned on both sides using end plates. Furthermore, the cells are bound together around their perimeter using steel straps.

[0033] To improve the energy density of battery devices, the capacity and number of cells in battery modules are also increasing. For example, the number of cells in a battery module has reached 26 or more. The size of an individual cell is also constantly increasing. This leads to an increase in the weight of the battery module, and also makes it easy for cells in the middle to sag and slip when using hoisting fixtures that only clamp at both ends during battery module assembly, thus affecting the safety of battery module assembly.

[0034] To ensure safety during battery module assembly, some embodiments of this application provide a battery assembly device. The battery assembly device employs an adsorption mechanism to adsorb the battery module onto one side of its top, a first clamping mechanism to clamp both ends of the battery module, and a second clamping mechanism to clamp both sides of the battery cells within the battery module. The adsorption mechanism ensures a stable adsorption force on the battery cells. The first clamping mechanism clamps the battery module along its length, and the second clamping mechanism clamps the battery cells along their width. Through the cooperation between the adsorption mechanism and the various clamping mechanisms, the positions of different battery cells during lifting of the battery module can be effectively fixed, ensuring the relative positions of each cell remain stable. This prevents the cells from shifting or sagging due to gravity, thus ensuring safety during battery module assembly.

[0035] The following is combined with Figures 1 to 12 This application describes the structure of a battery assembly apparatus provided in some embodiments. Additionally, Figure 13 The structure of the battery module is shown. Figure 14 The structure of the end plate in the battery module is shown. Figure 15 The assembly structure between the battery module and the bottom frame of the housing is shown.

[0036] like Figures 1 to 12 As shown, some embodiments of this application provide a battery assembly device including a base 10, an adsorption mechanism 20, a first clamping mechanism 30, and a second clamping mechanism 40. The adsorption mechanism 20 is connected to the base 10. The first clamping mechanism 30 is connected to the base 10 and includes a first clamping member 31 and a second clamping member 32 spaced apart. The second clamping mechanism 40 includes a first clamping assembly 41 and a second clamping assembly 42 disposed opposite to each other. The first clamping assembly 41 includes a plurality of first driving members 411 and a plurality of first clamping members 412. The first clamping members 412 are connected to the output end of the first driving members 411 and are provided with a first clamping surface 4121. The second clamping assembly 42 includes a plurality of second driving members 421 and a plurality of second clamping members 422. The second clamping members 422 are connected to the output end of the second driving members 421. The second clamping members 422 are provided with a second clamping surface 4221, which is opposite to the orientation of the first clamping surface 4121.

[0037] The base 10 serves as a load-bearing foundation in the battery assembly equipment, enabling the assembly of other components and providing a traction base for vehicles and other towing devices. The base 10 may be equipped with lifting rings 11 to engage with the hooks of the traction device, forming a base for traction. The lifting rings 11 can be located on the top of the base 10, protruding from one side of the top surface. For example, the base 10 can be constructed from high-strength steel welded into a frame, with the lifting rings 11 fixed to the top surface of the frame. Multiple lifting rings 11 can be used, depending on the number of battery modules 1000 (…) being lifted. Figure 13 The length direction (as shown) is set to ensure stability at all points during hoisting.

[0038] The base 10, while ensuring its structural strength, can have pre-reserved open areas to reduce its weight. Furthermore, the base 10 can have flat surfaces and holes on its periphery for assembling other components. The outline of the base 10 can be consistent with or nearly consistent with the outline of the battery module 1000 being lifted. The base 10 can be constructed using crossbeams and longitudinal beams in a rectangular configuration. The crossbeams are longer, and their dimensions can be designed according to the length of the battery module 1000 being lifted. The longitudinal beams are shorter, and their dimensions can be set according to the width of the battery module 1000 being lifted. A reinforcing beam can also be installed between the two crossbeams to strengthen the structure at or near the center of the crossbeams.

[0039] The adsorption mechanism 20 plays an adsorption role in the battery assembly equipment, and can adsorb the battery cells 1100 in the battery module 1000. Figure 13 (As shown) on the surface. The adsorption mechanism 20 includes an adsorption member 21, which is provided with an adsorption surface 211, and the adsorption surface 211 faces the first direction (as shown). Figure 1(As indicated by arrow A). The adsorption surface 211 of the adsorption component 21 can adhere to the top surface of the battery cell 1100 and be adsorbed onto the top surface of the battery cell 1100 using vacuum adsorption. The adsorption component 21 can be a suction cup, such as a sponge suction cup, with a space inside the sponge suction cup to create a negative pressure environment. During adsorption, the sponge suction cup can be compressed first to firmly adhere to the top surface of the battery cell 1100, and then vacuum adsorption is performed on the top surface of the battery cell 1100. The sponge suction cup can also be compressed during the vacuum process until it is stably adsorbed onto the top surface of the battery cell 1100. There can be one or more adsorption components 21, with the adsorption surface 211 of the adsorption component 21 corresponding to the top surface of the battery cell 1100. The adsorption force formed by the adsorption component 21 on the battery cell 1100 can be adjusted to ensure the stability of the battery module 1000 during lifting. The adsorption component 21 can be positioned to avoid the positive electrode post 1110, negative electrode post 1120, and explosion-proof valve 1130, thus avoiding the electrode post and explosion-proof valve 1130 on the top surface of the battery cell 1100. The first direction is parallel to the height direction when the battery assembly equipment lifts the battery module 1000. When the battery assembly equipment lifts the battery module 1000, the adsorption surface 211 faces the downward-facing battery cell 1100.

[0040] The first clamping mechanism 30 functions as an end clamping device in the battery assembly equipment, applying clamping force along the length of the battery module 1000 to limit the movement at both ends of the battery module 1000. The first clamping member 31 and the second clamping member 32 are arranged opposite each other and can be adjusted to clamp the battery module 1000 at both ends. The distance between the first clamping member 31 and the second clamping member 32 is adjustable, meaning they can move relative to the base 10 in a direction that brings them closer or further apart. The position adjustment of the first clamping member 31 can be achieved through the first adjusting member 33, and the position adjustment of the second clamping member 32 can be achieved through the second adjusting member 34. The first clamping member 31 and the second clamping member 32 move along a second direction (…). Figure 1 The first adjusting member 33 is drivenly connected to the first pressing member 31, and the second adjusting member 34 is drivenly connected to the second pressing member 32, which are positioned relative to each other (as indicated by arrow B). The second direction is the direction that intersects with the first direction. For example, the second direction is the direction that forms a 90° angle with the first direction, or it can be the direction that forms an acute or obtuse angle with the first direction. Figure 1 The following example illustrates the second direction, which is parallel to the length of the battery module 1000.

[0041] In practice, the clamping force of the first clamping member 31 and the second clamping member 32 can be adjusted. During the process of clamping both ends of the battery module 1000 by the first clamping mechanism 30, pressure changes can be detected by detectors such as pressure gauges to avoid overpressure on the battery cell 1100 and to prevent the performance of the battery cell 1100 from being affected by overpressure.

[0042] The second clamping mechanism 40 plays a lateral clamping role in the battery assembly equipment, applying clamping force along the width direction of the battery cell 1100 in the battery module 1000, thereby limiting the position of the battery cell 1100 on both sides. The first clamping component 41 and the second clamping component 42 of the second clamping mechanism 40 are arranged corresponding to different sides of the battery cell 1100, along the third direction ( Figure 1 (As indicated by arrow C) are arranged relative to each other. The plurality of first clamping members 412 of the first clamping assembly 41 can clamp one side of the battery cell 1100, and the plurality of second clamping members 422 of the second clamping assembly 42 can clamp the other side of the battery cell 1100, thereby ensuring the battery cell 1100 is clamped and effectively fixing the position of the battery cell 1100 relative to the base 10. The third direction is the direction intersecting the first and second directions. For example, the third direction can be a direction forming a 90° angle with the first and second directions, or it can be a direction forming an acute or obtuse angle with the first and second directions. Figure 1 The following explanation uses the direction of the third direction parallel to the width of the cell 1100 in the battery module 1000 as an example.

[0043] The first driving member 411 and the first clamping member 412 are assembled to form a first clamping unit. The first clamping member 412 is driven by the first driving member 411, so that the first clamping surface 4121 of the first clamping member 412 can abut against one side of the battery cell 1100 along the width direction. The second driving member 421 and the second clamping member 422 are assembled to form a second clamping unit. The second clamping member 422 is driven by the second driving member 421, so that the second clamping surface 4221 of the second clamping member 422 can abut against the other side of the battery cell 1100 along the width direction. The first clamping unit and the second clamping unit can be set for the battery cell 1100, thereby ensuring that each battery cell 1100 has a corresponding first clamping member 412 and second clamping member 422 to cooperate and clamp it. In practice, the first clamping unit and the second clamping unit can maintain a one-to-one or one-to-many correspondence with the battery cell 1100. That is, one first clamping unit and one second clamping unit can be simultaneously clamped on opposite sides of one battery cell 1100, or simultaneously clamped on opposite sides of multiple battery cells 1100. Alternatively, one of the first clamping unit and the second clamping unit can maintain a one-to-one correspondence with the battery cell 1100, while the other maintains a one-to-many correspondence with the battery cell 1100.

[0044] The first clamping surface 4121 is the surface on which the first clamping member 412 abuts against one side of the battery cell 1100 along the width direction, and the second clamping surface 4221 is the surface on which the second clamping member 422 abuts against the other side of the battery cell 1100 along the width direction. The areas of the first clamping surface 4121 and the second clamping surface 4221 correspond to the size of the area where the battery cell 1100 is clamped. By controlling the areas of the first clamping surface 4121 and the second clamping surface 4221, it can be ensured that the battery cell 1100 is effectively clamped, while avoiding the battery cell 1100 being affected by overvoltage due to an excessively large clamping area, and also avoiding interference between the first clamping member 412 and the second clamping member 422 and other components when clamping the battery cell 1100. In practice, the first clamping member 412 and the second clamping member 422 can be controlled to avoid the steel strip 1300 of the battery module 1000. The first clamping surface 4121 and the second clamping surface 4221 can cooperate with the area of ​​the battery cell 1100 located above the steel strip 1300 by 80% to 90%, that is, the area of ​​the side surface of the battery cell 1100 is 2800 mm². 2 ~3200mm 2 The area is clamped. Alternatively, the first clamping member 412 and the second clamping member 422 can be clamped on the outer side of a portion of the steel strip 1300, thus forming a larger clamping area. In some embodiments, the area of ​​the first clamping surface 4121 and the second clamping surface 4221 is 2500 mm². 2 ~4000mm 2 Optionally, the area of ​​the first clamping surface 4121 and the second clamping surface 4221 is 2800 mm². 2 ~3200mm 2 Optionally, the areas of the first clamping surface 4121 and the second clamping surface 4221 can be 2500 mm². 2 3000 mm 2 3500 mm 2 Or 4000mm 2 .

[0045] The battery assembly equipment provided in some embodiments of this application has an adsorption mechanism 20, a first clamping mechanism 30, and a second clamping mechanism 40 connected to a base 10. The adsorption mechanism 20 can adsorb from the top of the battery module 1000, and the first clamping mechanism 30 and the second clamping mechanism 40 can clamp from all sides of the battery module 1000. Through the cooperation between the adsorption mechanism 20, the first clamping mechanism 30, and the second clamping mechanism 40, the battery module 1000 can be stably adsorbed while effectively clamping and limiting the battery module 1000, thereby preventing the battery cells 1100 in the battery module 1000 from sagging or slipping due to gravity during hoisting, and ensuring safety when hoisting the battery module 1000.

[0046] In some embodiments, the battery assembly equipment further includes a limiting mechanism 50 connected to the base 10. The limiting mechanism 50 includes a plurality of limiting members 51 movably connected to the base 10. The limiting members 51 can be moved relative to the base 10 to enter a movement path of the first clamping member 412 away from the second clamping member 422 or the second clamping member 422 away from the first clamping member 412.

[0047] The limiting mechanism 50 can limit the return of the first clamping member 412 and the second clamping member 422. Specifically, the limiting member 51 of the limiting mechanism 50 can change its position by moving relative to the base 10, thereby changing its own state. When the limiting member 51 moves into the movement path of the first clamping member 412 or the second clamping member 422, it is in a first state, that is, it can restrict the first clamping member 412 or the second clamping member 422 from returning to its initial position. At this time, the limiting member 51 is located on the side of the first clamping member 412 away from the first clamping surface 4121 or the side of the second clamping member 422 away from the second clamping surface 4221, that is, it is located on the return path of the first clamping member 412 or the second clamping member 422. After the battery module 1000 is assembled, the first driving member 411 drives the first clamping member 412 to return to its original position, and the second driving member 421 drives the second clamping member 422 to return to its original position. The clamping member 412 or the second clamping member 422 will continue to return to its original position until it hits the limiting member 51 and stops returning to its original position. Then the clamping member on the cell 1100 can be released. Under the condition of ensuring that it will not hit other battery modules 1000, the first clamping member 412 or the second clamping member 422 can be released from the cell 1100, thereby controlling the safe transfer of the battery assembly equipment.

[0048] Before the battery assembly equipment is ready to lift the next set of battery modules 1000, the limiting member 51 can be moved to a retraction path away from the first clamping member 412 or the second clamping member 422. At this time, the limiting member 51 is in the second state, and the first driving member 411 can continue to drive the first clamping member 412 to retract to the initial position, and the second driving member 421 can continue to drive the second clamping member 422 to retract to the initial position.

[0049] In practice, the limiting member 51 can be configured to correspond to either the first clamping member 412 or the second clamping member 422, meaning the number of limiting members 51 is the same as the number of first clamping members 412 or second clamping members 422. The limiting member 51 can also simultaneously limit multiple first clamping members 412 or multiple second clamping members 422; that is, the limiting member 51 includes multiple limiting parts, each of which can limit the corresponding first clamping member 412 or second clamping member 422. Multiple limiting members 51 can be controlled individually or connected to form a whole for synchronous control.

[0050] In addition, both the first clamping member 412 and the second clamping member 422 can be equipped with limiting members 51 for limiting.

[0051] In some embodiments, the sides of the first clamping member 412 and the second clamping member 422 may be provided to avoid collisions, so that the first clamping member 412 and the second clamping member 422 are reserved with a height of at least 30mm, so as to avoid collisions between the first clamping member 412 or the second clamping member 422 and other battery modules 1000 when the battery module 1000 is lowered.

[0052] like Figure 3 As shown, the limiting mechanism 50 may further include a movable member 52. The movable member 52 is located on one side of the first clamping assembly 41 or on one side of the second clamping assembly 42, and the movable member 52 is connected to a plurality of limiting members 51.

[0053] The movable component 52, by connecting with multiple limiting components 51, can connect the multiple limiting components 51 into a whole, thereby enabling synchronous state control of the multiple limiting components 51 using the movable component 52, reducing the difficulty of movement control of the multiple limiting components 51. In practice, the movable component 52 can be configured as an elongated strip to connect with multiple limiting components 51.

[0054] In practice, the movement of the movable part 52 can be achieved through manual control or through automatic control.

[0055] like Figures 3 to 5 As shown, the base 10 may be provided with a fixing plate 101. The fixing plate 101 is located on one side of the first clamping assembly 41 or the second clamping assembly 42. The fixing plate 101 is provided with a channel, and the limiting member 51 passes through the channel and is movably engaged with the base 101.

[0056] The fixing plate 101 is located on one side of the base 10, providing an assembly base for the first clamping assembly 41 or the second clamping assembly 42, as well as for components such as the limiting member 51 and the moving member 52. The channel provided in the fixing plate 101 can guide the movement of the limiting member 51, ensuring that the limiting member 51 moves along a predetermined path and preventing the limiting member 51 from easily deviating in position, which would prevent it from effectively limiting the first clamping member 412 or the second clamping member 422.

[0057] Meanwhile, the movable member 52 can be held on one side of the fixed plate 101 and move on the side of the fixed plate 101 away from the first clamping assembly 41 or the second clamping assembly 42, so as to control the multiple limiting members 51 to change state.

[0058] In practice, a positioning sleeve 1011 can be set at the position of the fixed plate 101 corresponding to the channel to ensure that a large limiting area is formed for the limiting member 51, to ensure the accuracy of the limiting member 51 during movement, and to prevent the limiting member 51 from detaching.

[0059] like Figure 3 As shown, the limiting mechanism 50 may also include a positioning member 53. The positioning member 53 is connected to the moving member 52, and the distance between the positioning member 53 and the fixed plate 101 is less than the distance between the moving member 52 and the fixed plate 101.

[0060] The positioning member 53 is connected to the side of the movable member 52 closest to the first clamping assembly 41 or the second clamping assembly 42. The distance between the positioning member 53 and the fixed plate 101 is less than the distance between the movable member 52 and the fixed plate 101. When the movable member 52 approaches the fixed plate 101, the positioning member 53 will preferentially abut against the fixed plate 101, thereby controlling the falling position of the movable member 52 and limiting the movement position of the movable member 52. At the same time, the positioning member 53 also enables the movable member 52 to form a gap with the fixed plate 101 after it has moved into place, so that the movable member 52 can be reset after the limiting member 52 has completed its limiting function.

[0061] In practice, the movement of the movable part 52 can be controlled manually or by setting up a drive mechanism and a reset mechanism. For example, the movable part 52 can be equipped with a grip so that the operator can hold it and move it. Alternatively, a cylinder can be set on the fixed plate 101, and the movable part 52 can be moved by the extension and retraction of the cylinder. Springs or other components can also be used to achieve automatic reset of the movable part 52.

[0062] In addition, the positioning member 53 can be an elastic member so as to provide a buffering effect when the positioning member 53 contacts the fixing plate 101.

[0063] In some embodiments, the engagement position between the positioning member 53 and the moving member 52 can be adjusted. That is, the positioning member 53 can adjust the maximum distance between itself and the fixed plate 101 by changing its connection position with the moving member 52, thereby changing the restriction on the stopping position of the moving member 52. For example, the positioning member 53 can be a screw, stud, or bolt that forms a threaded engagement with the moving member 52. By screwing the positioning member 53 into different positions, the restriction position on the falling height of the moving member 52 can be changed, thereby adjusting the falling height of the moving member 52. This ensures that when the limiting member 51 enters the retracting movement path of the first clamping member 412 or the second clamping member 422, it can form a sufficient engagement area with the first clamping member 412 or the second clamping member 422.

[0064] like Figure 3As shown, the limiting mechanism 50 may also include a retaining member 54. The retaining member 54 is connected to the fixing plate 101 and forms a hollow area around the fixing plate 101, and part of the moving member 52 is located within the hollow area.

[0065] The hollow area formed by the abutment 54 and the fixing plate 101 can limit the movement height of the movable member 52, thereby controlling the extreme position of the movable member 52 during movement and preventing the limiting member 51 from detaching from the fixing plate 101. The height of the hollow area formed by the abutment 54 and the fixing plate 101 can be set according to the required movement height of the abutment 54, ensuring that the movable member 52 can move within a certain height range.

[0066] The supporting member 54 can be formed by bending sheet metal. The supporting member 54 includes a main body and a fixing part that bends and extends from the end of the main body. The main body can surround the fixing plate 101 to form a hollow area, and the fixing part can be fixed to the fixing plate 101 by fasteners. Within the area defined by the main body, the movement space of the moving member 52 can be controlled in multiple directions, effectively defining the movement area of ​​the moving member 52.

[0067] Additionally, a protrusion 521 may be provided on the movable member 52 to shorten the mating distance between the movable member 52 and the supporting member 54, thereby reducing the range of movement of the movable member 52. Furthermore, the protrusion height of the protrusion 521 can be adjusted to regulate the range of movement of the movable member 52. The protrusion 521 may be an elastic element to provide a cushioning effect when in contact with the supporting member 54.

[0068] In some embodiments, along a first direction, the size of the first clamping surface 4121 of a portion of the first clamping member 412 is larger than the size of the first clamping surface 4121 of the adjacent first clamping member 412, and / or, the size of the second clamping surface 4221 of a portion of the second clamping member 422 is larger than the size of the second clamping surface 4221 of the adjacent second clamping member 422.

[0069] In other words, among the plurality of first clamping members 412, some of the first clamping members 412 have a first clamping surface 4121 with a longer dimension along the first direction, and / or, among the plurality of second clamping members 422, some of the second clamping members 422 have a second clamping surface 4221 with a longer dimension along the first direction. The plurality of first clamping members 412 can be provided with first clamping surfaces 4121 of different sizes, forming clamping engagements with the side of the battery cell 1100 with different areas using the first clamping surfaces 4121 of different sizes. By lengthening the first clamping surface 4121 of some of the first clamping members 412, a larger range of abutment engagement can be formed between some of the first clamping members 412 and the side of the battery cell 1100, thereby increasing the stability of the engagement between the first clamping member 412 and the corresponding side of the battery cell 1100.

[0070] In some examples, the dimension of the first clamping surface 4121 of one of any two adjacent first clamping members 412 along the first direction may be larger than that of the other. Alternatively, a portion of the first clamping members 412 distributed at specific locations may have a longer first clamping surface 4121 along the first direction. That is, among the plurality of first clamping members 412 arranged along the second direction in the first clamping assembly 41, adjacent first clamping members 412 with a longer first clamping surface 4121 along the first direction may be distributed with an interval of one first clamping member 412 with a shorter first clamping surface 4121 along the first direction; or, only one, two, four, five, or eight first clamping members 412 may be provided with a longer first clamping surface 4121 along the first direction.

[0071] Furthermore, multiple second clamping members 422 can be provided with second clamping surfaces 4221 of different sizes, forming clamping engagements with the side of the battery cell 1100 with different areas using the second clamping surfaces 4221 of different sizes. By lengthening the second clamping surfaces 4221 of some of the second clamping members 422, a larger range of abutment engagement can be formed between some of the second clamping members 422 and the side of the battery cell 1100, thereby increasing the stability of the engagement between the second clamping members 422 and the corresponding side of the battery cell 1100.

[0072] In some examples, the dimension of the second clamping surface 4221 of one of any two adjacent second clamping members 422 along the second direction may be larger than the dimension of the second clamping surface 4221 of the other two along the second direction. Alternatively, a portion of the second clamping members 422 distributed at specific locations may have a second clamping surface 4221 that is longer along the second direction. That is, among the multiple second clamping members 422 arranged along the second direction in the second clamping assembly 42, adjacent second clamping members 422 with longer second clamping surfaces 4221 along the second direction may be distributed with a second clamping member 4222 having a shorter second clamping surface 4221 along the second direction spaced apart, or only one, two, four, five, or eight second clamping members 422 may be provided with a second clamping surface 4221 that is longer along the second direction.

[0073] In addition, a first clamping surface 4121 of some first clamping members 412 may be provided with a first connecting layer 4122, the surface of the first connecting layer 4122 away from the first clamping surface 4121 being an adhesive surface, and / or, a second clamping surface 4221 of some second clamping members 422 may be provided with a second connecting layer 4222, the surface of the second connecting layer 4222 away from the second clamping surface 4221 being an adhesive surface.

[0074] A first connecting layer 4122 is provided on the first clamping surface 4121 of the first clamping member 412, and at least one of the front and back sides of the first connecting layer 4122 is an adhesive surface. The front side of the first connecting layer 4122 corresponds to the surface of the first connecting layer 4122 away from the first clamping surface 4121, and the back side of the first connecting layer 4122 corresponds to the surface of the first connecting layer 4122 that is in contact with the first clamping surface 4121. The first connecting layer 4122 may be made of a flexible material with adhesive properties, or an adhesive layer may be covered on at least one side of the first connecting layer 4122. The first connecting layer 4122 may also be made of a material with a hardness less than that of the battery cell 1100 shell, so as to ensure that the first clamping member 412 does not cause damage to the surface of the battery cell 1100 when clamping the battery cell 1100. Furthermore, the first connecting layer 4122 can be bonded to the side of the battery cell 1100 using its own adhesive properties, thereby strengthening the tightness of the connection with the battery cell 1100 and reducing the squeezing of the battery cell 1100 when clamping it.

[0075] The second clamping surface 4221 of the second clamping member 422 is provided with a second connecting layer 4222, at least one of the front and back surfaces of the second connecting layer 4222 being an adhesive surface. The front surface of the second connecting layer 4222 corresponds to the surface of the second connecting layer 4222 away from the second clamping surface 4221, and the back surface of the second connecting layer 4222 corresponds to the surface of the second connecting layer 4222 that is in contact with the second clamping surface 4221. The second connecting layer 4222 can be made of a flexible material with adhesive properties, or an adhesive layer can be covered on at least one side of the second connecting layer 4222. The second connecting layer 4222 can also be made of a material with a hardness less than that of the battery cell 1100 shell, so as to ensure that the second clamping member 422 does not cause damage to the surface of the battery cell 1100 when clamping the battery cell 1100. Furthermore, the second connecting layer 4222 can be bonded to the side of the battery cell 1100 using its own adhesive properties, thereby strengthening the connection between the battery cell 1100 and reducing the compressive strength of the battery cell 1100 when clamping it.

[0076] In some embodiments, the surface of the first connecting layer 4122 away from the first clamping surface 4121 may be provided with a first slot 4123, the end of the first slot 4123 being through-through, and / or, the surface of the second connecting layer 4222 away from the second clamping surface 4221 may be provided with a second slot 4223, the end of the second slot 4223 being through-through.

[0077] The first slot 4123 is located on the front side of the first connecting layer 4122, corresponding to the side of the first connecting layer 4122 that abuts against the side of the battery cell 1100. The first slot 4123 can form a clearance space on one side of the first connecting layer 4122 to allow clearance for the position of the steel strip 1300 in the battery module 1000, so that when the first clamping member 412 is clamped against the side of the battery cell 1100, the steel strip 1300 can be accommodated within the first slot 4123. That is to say, a portion of the steel strip 1300 can be located within the first slot 4123 without affecting the tight abutment of the first clamping member 412 against the side of the battery cell 1100.

[0078] In practice, the width of the first slot 4123 can be greater than the width of the steel strip 1300. For example, the width of the first slot 4123 can exceed the width of the steel strip 1300 by 1mm to 3mm. The end of the first slot 4123 is through-hole, and the extension direction of the first slot 4123 is parallel to the second direction, which can correspond to the extension direction of a portion of the steel strip 1300 located on one side of multiple battery cells 1100 in the battery module 1000. Furthermore, the first slot 4123 can be provided corresponding to the elastic part or buffer part of the steel strip 1300, that is, a portion of the first clamping member 412 with a longer first clamping surface 4121 clamps the battery cell 1100 with the elastic part or buffer part of the steel strip 1300 on one side. The bottom of the first slot 4123 can be used to press the elastic part or buffer part of the steel strip 1300, thereby preventing the elastic part or buffer part of the steel strip 1300 from falling or shifting after the battery module 1000 is clamped at both ends.

[0079] The second slot 4223 is located on the front of the second connecting layer 4222, corresponding to the side of the second connecting layer 4222 that abuts against the side of the battery cell 1100. The second slot 4223 can form a clearance space on one side of the second connecting layer 4222 to allow clearance for the position of the steel strip 1300 in the battery module 1000, so that when the second clamping member 422 is clamped against the side of the battery cell 1100, the steel strip 1300 can be accommodated within the second slot 4223. That is to say, a portion of the steel strip 1300 can be located within the second slot 4223 without affecting the tight abutment of the second clamping member 422 against the side of the battery cell 1100.

[0080] In practice, the width of the second slot 4223 can be greater than the width of the steel strip 1300. For example, the width of the second slot 4223 can exceed the width of the steel strip 1300 by 1mm to 3mm. The end of the second slot 4223 is through-hole, and the extension direction of the second slot 4223 is parallel to the second direction, which can correspond to the extension direction of a portion of the steel strip 1300 located on one side of multiple battery cells 1100 in the battery module 1000. Furthermore, the second slot 4223 can be provided corresponding to the elastic part or buffer part of the steel strip 1300, that is, a portion of the second clamping member 422 with a longer second clamping surface 4221 clamps the battery cell 1100 with the elastic part or buffer part of the steel strip 1300 on one side. The bottom of the second slot 4223 can be used to press the elastic part or buffer part of the steel strip 1300, thereby preventing the elastic part or buffer part of the steel strip 1300 from falling or shifting after the battery module 1000 is clamped at both ends.

[0081] Furthermore, the lower sidewalls of the first slot 4123 and the second slot 4223 can be sloped. The sidewall slopes can create a clearance, and also facilitate the separation of the first connecting layer 4122 and the second connecting layer 4222 from the steel strip 1300. The slopes can be controlled within a range greater than 90°. For example, the lower sidewall of the first slot 4123 can form an angle of 100°, 110°, or 120° with the bottom wall, and the lower sidewall of the second slot 4223 can form an angle of 100°, 110°, or 120° with the bottom wall.

[0082] like Figure 8 and Figure 9 As shown, the second clamping mechanism 40 may further include a flexible member 43. The flexible member 43 includes a connected mounting portion 431 and an abutment portion 432. The mounting portion 431 is connected to the first clamping surface 4121 or the second clamping surface 4221, and the thickness of the mounting portion 431 is greater than the thickness of the abutment portion 432.

[0083] The flexible member 43 acts as a buffer, preventing damage to the surface of the battery cell 1100 when the first clamping member 412 or the second clamping member 422 clamps the battery cell 1100. The mounting portion 431 is the part that connects and fixes the flexible member 43 to the first clamping member 412 or the second clamping member 422, and the abutment portion 432 is the part of the flexible member 43 that is clamped on the side of the battery cell 1100. The thickness of the mounting portion 431 corresponds to the dimension of the mounting portion 431 along a third direction, and the thickness of the abutment portion 432 corresponds to the dimension of the abutment portion 432 along a third direction. The mounting portion 431 has a larger thickness than the abutment portion 432, which ensures that the flexible member 43 and the fastener form a larger range of fit, thereby ensuring the tightness of the connection of the flexible member 43 on the first clamping member 412 or the second clamping member 422.

[0084] In addition, the thickness difference between the mounting part 431 and the abutment part 432 can be used to position the battery cell 1100 when clamping it. When the abutment part 432 abuts against the side of the battery cell 1100, the bottom surface of the mounting part 431 abuts against the top surface of the battery cell 1100. This ensures that the clamping position of the battery cell 1100 by different clamping members is consistent through the flexible member 43, and ensures that the pressure on each battery cell 1100 is relatively uniform.

[0085] For a first clamping member 412 with a longer first clamping surface 4121, or a second clamping member 422 with a longer second clamping surface 4221, a longer flexible member 43 can be provided, such that the flexible member 43 basically covers the first clamping surface 4121 or the second clamping surface 4221. Furthermore, the abutting portion 432 of the flexible member 43 can be provided with a serrated or striped structure to increase the roughness of the contact portion between the flexible member 43 and the side of the battery cell 1100, thereby increasing the frictional resistance when the flexible member 43 abuts against the side of the battery cell 1100, and thus ensuring the clamping effect of the first clamping member 412 or the second clamping member 422 on the battery cell 1100.

[0086] like Figure 8 As shown, a flexible member 43 is connected to the first clamping surface 4121 of the first clamping member 412. The mounting portion 431 of the flexible member 43 has mounting holes 4311 for fasteners to pass through and connect with the first clamping member 412 for fixation. There can be two mounting holes 4311, arranged along a second direction. Additionally, the first clamping member 412 is connected to the output end of the first driving member 411. The first driving member 411 is a cylinder, mounted on the first base 4111. Simultaneously, a first slider 413 is connected to the top of the first clamping member 412 via a mounting block. The first slider 413 cooperates with a first slide rail 414, which is mounted on the side away from the first slider 413 via a first base 415. During movement, the first clamping member 412 is guided by the slider-slide rail mechanism to ensure its stability during clamping and movement.

[0087] like Figure 9As shown, the second clamping surface 4221 of the second clamping member 422 is connected to a flexible member 43. The mounting portion 431 of the flexible member 43 is provided with mounting holes 4311 for fasteners to pass through and connect and fix to the second clamping member 422. There can be two mounting holes 4311, which are arranged along the second direction. In addition, the second clamping member 422 is connected to the output end of the second driving member 421. The second driving member 421 is a cylinder, which is mounted at the second base 4211. At the same time, a second slider 423 is connected to the top of the second clamping member 422 via a mounting block. The second slider 423 cooperates with the second slide rail 424, which is mounted on the side away from the second slider 423 via a second base 425. The second clamping member 422 is guided by the slider-slide rail mechanism during movement to ensure the stability of the second clamping member 422 during clamping and movement.

[0088] In some embodiments, the abutment portion 432 may be provided with a groove recessed from the surface inward, and the end of the groove is through-hole.

[0089] The groove is located on the front side of the flexible member 43, corresponding to the side where the flexible member 43 abuts against the side of the battery cell 1100. The groove can form a clearance space on one side of the flexible member 43 to allow clearance for the position of the steel strip 1300 in the battery module 1000, so that when the first clamping member 412 or the second clamping member 422 is clamped on the side of the battery cell 1100, the steel strip 1300 can be accommodated in the groove. That is to say, a portion of the steel strip 1300 can be located in the groove without affecting the tight abutment of the first clamping member 412 or the second clamping member 422 against the side of the battery cell 1100.

[0090] In practice, the width of the groove can be greater than the width of the steel strip 1300. For example, the width of the groove can exceed the width of the steel strip 1300 by 1mm to 3mm. The end of the groove is through-hole, and the extension direction of the groove is parallel to the second direction, which can correspond to the extension direction of a portion of the steel strip 1300 located on one side of multiple battery cells 1100 in the battery module 1000. Furthermore, the groove can be provided corresponding to the elastic part or buffer part of the steel strip 1300, that is, a portion of the longer flexible member 43 can clamp the battery cell 1100 that has the elastic part or buffer part of the steel strip 1300 on one side. The bottom of the groove can be used to press the elastic part or buffer part of the steel strip 1300, thereby preventing the elastic part or buffer part of the steel strip 1300 from falling or shifting after the battery module 1000 is clamped at both ends.

[0091] like Figure 10 and Figure 11As shown, a first buffer layer 311 may be provided on the side of the first clamping member 31 near the second clamping member 32, and at least one first protrusion 312 may be provided on the side of the first buffer layer 311 near the second clamping member 32. And / or, a second buffer layer 321 may be provided on the side of the second clamping member 32 near the first clamping member 31, and at least one second protrusion 322 may be provided on the side of the second buffer layer 321 near the first clamping member 31.

[0092] The first buffer layer 311 is located on one side of the battery module 1000 pressed by the first clamping member 31. The first buffer layer 311 can play a buffering role when the first clamping member 31 presses one end of the battery module 1000, thereby avoiding deformation or crushing at the end of the battery module 1000. The first buffer layer 311 can correspond to the end plate 1200 at the end of the battery module 1000. Figure 14 As shown, the first protrusion 312 can engage with the positioning hole 1210 on the outer surface of the end plate 1200, thereby ensuring that the first clamping member 31 can be tightly fitted to one end of the battery module 1000. The first protrusion 312 can effectively fix the position of the first clamping member 31 relative to the end plate 1200 at one end of the battery module 1000, ensuring that the first clamping member 31 will not move relative to the end plate 1200 at one end of the battery module 1000 during the hoisting of the battery module 1000, thereby ensuring the clamping stability of the first clamping member 31 on the end of the battery module 1000.

[0093] The second buffer layer 321 is located on one side of the battery module 1000 pressed by the second clamping member 32. The second buffer layer 321 can buffer the battery module 1000 when the second clamping member 32 presses one end of the battery module 1000, thereby preventing deformation or crushing of the end of the battery module 1000. The second buffer layer 321 can be set corresponding to the end plate 1200 at the end of the battery module 1000. The second protrusion 322 can cooperate with the positioning hole 1210 on the outer side of the end plate 1200, thereby ensuring that the second clamping member 32 can be tightly fitted to one end of the battery module 1000. The second protrusion 322 can effectively fix the position of the second clamping member 32 relative to the end plate 1200 at one end of the battery module 1000, ensuring that the second clamping member 32 will not move relative to the end plate 1200 at one end of the battery module 1000 during the hoisting of the battery module 1000, thereby ensuring the clamping stability of the second clamping member 32 on the end of the battery module 1000.

[0094] In practice, the first clamping member 31 and the second clamping member 32 can be separately disposed at both ends of the base 10. The position of the first clamping member 31 is adjusted by the first adjusting member 33, and the position of the second clamping member 32 is adjusted by the second adjusting member 34. To ensure the clamping effect of the first clamping member 31 and the second clamping member 32, a guide mechanism can be provided to guide the movement of the first clamping member 31 and the second clamping member 32, and a screw and nut mechanism can be used to achieve locking after adjustment.

[0095] A first base can be installed in the area where the first clamping member 31 is located. A transmission mechanism can be installed on the top of the first base. The first adjusting member 33 is connected to the input end of the transmission mechanism, and the first clamping member 31 is connected to the output end of the transmission mechanism. The transmission mechanism can be a screw and nut mechanism that can convert rotary motion into linear motion. That is, the first adjusting member 33 can be a handwheel, which drives the first clamping member 31 to move in the second direction.

[0096] To ensure the stability of the first clamping member 31 during movement, a slide rail slider guide mechanism can be provided at both the top and bottom of the first base. The synchronous guidance of the upper and lower slide rail slider guide mechanisms ensures the stability of the first clamping member 31 during movement.

[0097] Additionally, a second base can be installed in the area where the second clamping member 32 is located. A transmission mechanism can be installed on the top of the second base. The second adjusting member 34 is connected to the input end of the transmission mechanism, and the second clamping member 32 is connected to the output end of the transmission mechanism. The transmission mechanism can be a screw and nut mechanism that can convert rotary motion into linear motion. That is, the second adjusting member 34 can be a handwheel, which drives the second clamping member 32 to move in the second direction.

[0098] To ensure the stability of the second clamping member 32 during movement, a slide rail slider guide mechanism can be provided at both the top and bottom of the second base. The synchronous guidance of the upper and lower slide rail slider guide mechanisms ensures the stability of the second clamping member 32 during movement.

[0099] like Figure 12As shown, the structure at the second clamping member 32 is illustrated as an example. The second adjusting member 34 adopts a three-spoke handwheel, which is connected to the lead screw 341. The two ends of the lead screw 341 are respectively limited by the first fixed seat 3411 and the second fixed seat 3412. The lead screw 341 and the nut sleeve 342 are engaged, and the nut sleeve 342 is located between the first fixed seat 3411 and the second fixed seat 3412. The first fixed seat 3411 and the second fixed seat 3412 are mounted on the L-shaped support plate 102, and the L-shaped support plate 102 can be provided with reinforcing ribs. Two upper sliders 3431 and an upper guide rail 3432 are installed above the L-shaped support plate 102. A limit seat 3433 is provided at the outer end of the upper guide rail 3432. The limit seat 3433 is fixed on the L-shaped support plate 102 to prevent the upper sliders 3431 from separating from the upper guide rail 3432. A sliding member 343 is mounted on the upper slider 3431. The middle of the sliding member 343 is connected to the nut sleeve 342. The bottom of the sliding member 343 is connected to the screw 344. A pressure sensor 345 is mounted on the front end of the screw 344. The pressure sensor 345 is fixed in the middle of the second clamping member 32 and is communicatively connected to the pressure display 346. Reinforcing ribs are installed on the left and right sides of the back of the second clamping member 32. A lower slider 323 and a lower slide rail 324 are installed on the top of the second clamping member 32. When the second clamping member 32 is driven by the screw and nut transmission mechanism, it can be guided by the slider and slide rail mechanism on the upper and lower sides of the L-shaped support plate 102 to ensure the stability of the second clamping member 32 during movement.

[0100] In some embodiments, the adsorption mechanism 20 may include a first adsorption member 22 and a second adsorption member 23, with the first adsorption member 22 close to the first clamping assembly 41 and the second adsorption member 23 close to the second clamping assembly 42, and a gap between the first adsorption member 22 and the second adsorption member 23.

[0101] The first adsorption element 22 and the second adsorption element 23 in the adsorption mechanism 20 are spaced apart and reserved to avoid the liquid injection hole and explosion-proof valve 1130 on the top surface of the battery cell 1100 when the adsorption mechanism 20 adsorbs the top surface of the battery cell 1100. This avoids the protruding structure on the top surface of the battery cell 1100 from affecting the normal progress of the adsorption process.

[0102] In practice, the distance between the first adsorption element 22 and the second adsorption element 23 can be 50mm~70mm, 70mm~90mm, 90mm~110mm, or 110mm~120mm. For example, the distance between the first adsorption element 22 and the second adsorption element 23 can be 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, or 120mm. By controlling the distance between the first adsorption element 22 and the second adsorption element 23, interference between the adsorption element 21 and the protruding structure on the top surface of the battery cell 1100 can be effectively avoided when the adsorption element 21 adsorbs the battery cell 1100. It can also avoid insufficient adsorption area due to the adsorption element 21 being too far away, thereby avoiding affecting the adsorption force formed by the adsorption element 21 on the battery cell 1100.

[0103] A sheet metal cover 12 can be installed in the middle area above the base 10. The sheet metal cover 12 can be equipped with components such as a reset button 13, a clamping button 14, an exhaust button 15, a release button 16, and a vacuum pressure switch 17. Sponge suction cups are installed on both sides below the base 10, and a reserved area in the middle is used to avoid the poles and other structures on the surface of the battery cell 1100.

[0104] The structures of the first adsorption element 22 and the second adsorption element 23 can be the same or different. Taking the first adsorption element 22 and the second adsorption element 23 as having the same structure as an example, the first adsorption element 22 can be provided with multiple first grooves 221, and the second adsorption element 23 can be provided with multiple second grooves 231. The first grooves 221 of the first adsorption element 22 can avoid one of the positive electrode post 1110 and the negative electrode post 1120, and the second grooves 231 of the second adsorption element 23 can avoid the other of the positive electrode post 1110 and the negative electrode post 1120. In practice, the width of the first adsorption element 22 and the second adsorption element 23 can be 100mm, and the first grooves 221 and the second grooves 231 can be set as rectangular grooves, with the length and width dimensions of the rectangular grooves reserved at 73mm and 45mm, respectively.

[0105] like Figure 1 As shown, the battery assembly equipment may also include multiple positioning elements 60. The positioning elements 60 are movably connected to the base 10.

[0106] The positioning component 60 serves a positioning function when the battery assembly equipment lifts the battery module 1000. The positioning component 60 extends along the first direction and is relatively long. The bottom of the positioning component 60 protrudes a certain length from the bottom of the base 10. When the battery assembly equipment is in place, the positioning component 60 is positioned with the guide holes on the battery module support device, ensuring that the adsorption mechanism 20 of the battery assembly equipment is aligned with the top of the battery module 1000, the first clamping mechanism 30 is aligned with both ends of the battery module 1000, and the second clamping mechanism 40 is aligned with both sides of the battery module 1000.

[0107] The positioning element 60 can be installed on the guide block 103 provided on the base 10 and locked using fasteners such as bolts 104. The guide block 103 can be installed below the base 10, and the positioning element 60 extends downward through the guide block 103, thereby limiting the movement direction of the positioning element 60.

[0108] In practice, the positioning process can also be accomplished by setting up a vision mechanism. This mechanism positions the relative positions of each component of the battery assembly equipment to the battery module 1000, ensuring precise alignment between each component and its corresponding area on the battery module 1000. Alternatively, a vision mechanism can be used in conjunction with a positioning mechanism to perform mechanical locking positioning after visual positioning, ensuring the accuracy of the position when the battery assembly equipment and the battery module 1000 align.

[0109] Some embodiments of this application also provide a method for manufacturing a battery device. The method for manufacturing a battery device includes the following steps: Step S110: Obtain a battery module, which includes multiple battery cells.

[0110] The battery module is formed by connecting multiple cells. The cells can be prismatic rechargeable batteries, effectively utilizing the internal space of the casing and increasing the energy density of the battery device. Multiple cells can be connected using CCS (Computer-Assisted Cell) modules, and thermal insulation pads can be placed between adjacent cells to prevent heat transfer. The thickness sides of the multiple cells can be limited by end plates, which can then be bound to the cells with straps to form a single unit.

[0111] Step S120: Obtain battery device manufacturing equipment, which includes the battery device assembly equipment described above.

[0112] The battery assembly equipment includes an adsorption mechanism, a first clamping mechanism, and a second clamping mechanism. The battery assembly equipment can be moved by a traction device, allowing the base to move close to the battery module. The adsorption mechanism of the battery assembly equipment can adsorb onto the top surface of the battery module, the first clamping mechanism can clamp both ends of the battery module, and the second clamping mechanism can clamp both sides of the battery cells within the battery module.

[0113] Step S130: Move the base of the traction battery assembly equipment to a position close to the battery module and allow the adsorption mechanism to adsorb the surface of the battery cell.

[0114] In practice, after the battery assembly equipment and the battery module to be assembled are positioned, the adsorption mechanism can be controlled to make close contact with the top surface of the battery cell. When a sponge suction cup is used as the adsorption component, the sponge suction cup will be compressed to a certain extent. After the adsorption component makes close contact with the corresponding area of ​​the top surface of the battery cell, the adsorption component is controlled to adhere to the top surface of the battery cell. Alternatively, after the adsorption component makes contact with the top surface of the battery cell, it can be controlled to adhere to the top surface of the battery cell more and more tightly.

[0115] Step S140: Control the first clamping member to move closer to the second clamping member, and / or control the second clamping member to move closer to the first clamping member, so that the first clamping member and the second clamping member are clamped at both ends of the battery module.

[0116] By controlling the movement of the first clamping member and / or the second clamping member in the first clamping mechanism, the two ends of the battery module are clamped, ensuring that the battery module is pressed and limited in the length direction.

[0117] Step S150: Drive the first clamping member to move by the first driving member, and drive the second clamping member to move by the second driving member, so that the first clamping surface and the second clamping surface abut against the two sides of the battery cell.

[0118] The second clamping mechanism can clamp the battery cell from both sides, so that each battery cell in the battery module can be pressed and limited in the width direction.

[0119] Step S160: Hoist the battery module into the housing to form a battery device.

[0120] After the battery assembly equipment completes the adsorption and clamping of the battery module, it can move via a traction base to lift and transfer the battery module, thus completing the assembly process. The housing can be formed by a bottom platform and a top cover, or by a bottom receiving cavity and a top cover. When the housing has a bottom platform, the battery module can be directly lifted and transferred to the bottom platform; releasing the adsorption and clamping completes the assembly. When the housing has a bottom receiving cavity, the clamping can be released first, and then the battery module can be placed into the receiving cavity to complete the assembly. The battery module assembly process can occur once or multiple times, meaning the number of battery modules placed in the housing can be one or more. For example, the battery module assembly process can occur four times, and the number of battery modules placed in the housing can be four (…). Figure 15As shown, four battery modules 1000 are sequentially assembled onto the bottom frame 2000 of the housing. After the assembly of multiple battery modules is completed, different parts of the housing can be assembled, and the battery modules can be packaged to form a battery device.

[0121] In some embodiments, before the adsorption mechanism adsorbs the surface of the battery cell, the following steps are further included: Step S1301: The position of the battery module is detected by the detection mechanism, so that the positioning mechanism is aligned with the guide structure of the battery module support device.

[0122] The inspection mechanism can position the battery module before the adsorption mechanism adsorbs it, ensuring that the adsorption mechanism is aligned with the top surface of the battery module. The positioning mechanism, in conjunction with the guide structure of the battery module carrier, achieves mechanical positioning between the battery assembly equipment and the battery module carrier, thereby ensuring a stable relative position between the adsorption mechanism and the battery module. In practice, the inspection mechanism can be a vision inspection mechanism.

[0123] Step S1302: Move the traction base to make the positioning mechanism cooperate with the guide structure.

[0124] After the positioning mechanism and the guiding mechanism work together, the adsorption mechanism can adsorb the battery module, thus enabling the battery module assembly equipment to work together with the battery module.

[0125] In practice, the vacuum adsorption process can begin after the adsorption surface of the adsorption component has fully adhered to the surface of the battery cell. Alternatively, the first clamping mechanism can be controlled to clamp both ends of the battery module first, compressing the adsorption component by 1mm to 3mm to ensure a tight fit between the adsorption component and the battery cell surface before initiating the vacuum adsorption process.

[0126] After the adsorption mechanism adsorbs the surface of the battery cell and the first clamping mechanism clamps both ends of the battery module, the second clamping mechanism can be controlled to clamp each battery cell in the battery module to ensure that each battery cell is in a clamped state, thereby preventing the battery cells from shifting or falling off during the assembly process.

[0127] In addition, before the adsorption mechanism begins adsorbing the battery cell, a portion of the longer first and second clamping members can be controlled to clamp the battery cell, thus completing the positioning process. The first and second clamping members can engage with protrusions on the steel strip to complete the positioning process, ensuring that the first and second clamping members are clamped on both sides of the battery cell at specific positions. After the longer first and second clamping members have completed clamping, the adsorption mechanism and the first clamping mechanism can be controlled to perform the adsorption and clamping processes respectively, and finally, the remaining first and second clamping members are controlled to complete the clamping of the battery cell's sides.

[0128] Some embodiments of this application also provide a battery device. The battery device is manufactured using the battery device manufacturing method described above. The battery device includes a housing and a battery module. The battery module is located inside the housing and includes multiple battery cells.

[0129] A battery device includes a casing and battery cells housed within the casing. Each battery cell is an energy storage unit within the battery device, and cells can be combined in a specific number to form a battery module. Increasing the number of cells can effectively increase the energy storage capacity of the battery device. For example, a long battery module in a battery device may use as many as 26 cells, with each cell ranging from 260mm to 650mm in length, 70mm to 80mm in width, and 180mm to 300mm in height.

[0130] The housing provides a space to house the battery cells, and can have various structures. In some embodiments, the housing may include a first part and a second part, which overlap each other, together defining a space for housing the battery cells. The second part may be a hollow structure with one open end, and the first part may be a plate-like structure, with the first part covering the open side of the second part so that the first and second parts together define the space. Alternatively, both the first and second parts may be hollow structures with one open side, with the open side of the first part covering the open side of the second part. Of course, the housing formed by the first and second parts can be of various shapes, such as a cylinder, a cuboid, etc.

[0131] In a battery device, a cell can be a single cell or multiple cells. Multiple cells can be connected in series, parallel, or a combination thereof. A combination thereof means that multiple cells are connected in both series and parallel configurations. Multiple cells can be directly connected in series, parallel, or a combination thereof to form a whole, which is then housed within a casing. Alternatively, a battery device can consist of multiple cells first connected in series, parallel, or a combination thereof to form battery modules, which are then connected in series, parallel, or a combination thereof to form a whole, which is also housed within a casing.

[0132] The battery device may also include other structures, such as a busbar for electrical connection between multiple cells.

It can meet the needs of long-term energy storage, achieving long-term energy storage of 4 hours or more, for example, it can be applied to energy storage scenarios such as 5 hours, 6 hours, and 8 hours. Long-term energy storage refers to the ability to continuously discharge at rated power for 4 hours or even longer, or to achieve large-scale, low-cost energy storage for several days or months.
