[0034] The following detailed description is provided to help the reader gain a comprehensive understanding of the methods, devices, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent upon understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein. Rather, except for operations that must occur in a particular order, changes may be made that will be apparent upon understanding the disclosure of this application. Furthermore, descriptions of features known in the art may be omitted for clarity and brevity.

[0035] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0036] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, it may be directly “on,” “connected to,” “coupled to,” “over,” or “overlaying” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on,” “directly connected to,” “directly coupled to,” “directly over,” or “directly covering” another element, there may be no other elements intervening therebetween.

[0037] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0038] Although terms such as "first," "second," and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Rather, these terms are used only to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Thus, a first member, component, region, layer, or portion in the examples described herein may also be referred to as a second member, component, region, layer, or portion without departing from the teachings of the examples.

[0039] For ease of description, spatial relational terms such as "above," "upper," "below," and "lower" may be used herein to describe the relationship of one element to another element as shown in the accompanying drawings. Such spatial relational terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, an element described as being "above" or "upper" relative to another element would subsequently be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientations "above" and "below," depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relational terms used herein will be interpreted accordingly.

[0040] The terms used herein are intended only to describe various examples and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the singular is intended to include the plural. The terms "comprise," "include," and "have" list the presence of stated features, quantities, operations, components, elements, and / or combinations thereof, but do not preclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0041] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include changes in shapes that occur during manufacturing.

[0042] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0043] The following will be combined Figures 1 to 7 The battery cell 71 assembly system of the present application is described. Figures 1 to 7 In the embodiment, the first direction L1, the second direction L2 and the third direction L3 intersect each other, wherein the intersection may be vertical, and the verticality here may be 90±5°.

[0044] like Figures 1 to 5As shown, the battery cell assembly system includes an assembly mechanism 10, a conveying mechanism 8 and a handling mechanism 9, the conveying mechanism 8 is used to convey the battery cell 71, the assembly mechanism 10 is used to clamp the mounting bracket 72, and the handling mechanism 9 can move the battery cell 71 on the conveying mechanism 8 to the mounting bracket 72; the assembly mechanism 10 includes a support plate 32, a driving component 1, a first clamping member 2a and a second clamping member 2b, the first clamping member 2a and the second clamping member 2b are arranged at intervals, and the mounting bracket 72 is placed on the support plate 32 and is located between the first clamping member 2a and the second clamping member 2b; the driving component 1 can drive one of the first clamping member 2a and the second clamping member 2b to move, so that the first clamping member 2a and the second clamping member 2b respectively clamp the mounting bracket 72 from the opposite ends of the mounting bracket 72.

[0045] When using the battery cell assembly system of the present application to assemble battery cells 71, first place the first mounting bracket 72 between the first clamping member 2a and the second clamping member 2b, and then drive one of the first clamping member 2a and the second clamping member 2b to move through the driving assembly 1, so that the first clamping member 2a and the second clamping member 2b clamp the mounting bracket 72 from opposite ends of the first mounting bracket 72. Then, the multiple battery cells 71 on the conveying mechanism 8 are correspondingly loaded into the mounting holes on the first mounting bracket 72 through the conveying mechanism 9, thereby completing the installation of the first mounting bracket 72. Then, insert the second mounting bracket 72 between the first clamping member 2a and the second clamping member 2b. At this time, the multiple mounting holes on the second mounting bracket 72 are respectively aligned with the multiple battery cells 71. Then, press the second mounting bracket 72 downward to put the second mounting bracket 72 on the top of the multiple battery cells 71. The two mounting brackets 72 can be positioned by the first clamping member 2a and the second clamping member 2b, thereby reducing the risk of scratching the insulating skin on the top surface of the battery cell 71 when the second mounting bracket 72 is installed.

[0046] Optionally, the conveying mechanism 8 may be a transmission belt, and the handling mechanism 9 may be a robot arm.

[0047] In an embodiment of the present application, the drive assembly 1 includes a bidirectional screw 11 and a drive motor 12. The bidirectional screw 11 extends along a first direction L1. The drive motor 12 is connected to the bidirectional screw 11 to drive the bidirectional screw 11 to rotate. The first clamping member 2a and the second clamping member 2b are respectively arranged at two positions of the bidirectional screw 11 with opposite rotation directions. When the drive motor 12 drives the bidirectional screw 11 to rotate, the first clamping member 2a and the second clamping member 2b can move toward or relative to each other along the bidirectional screw 11, so that the first clamping member 2a and the second clamping member 2b can approach or move away from each other, thereby achieving the clamping or release of the mounting bracket 72 supported on the support plate 32. In addition, the direction of movement of the first clamping member 2a and the second clamping member 2b can be changed by changing the rotation direction of the drive motor 12, so that the first clamping member 2a and the second clamping member 2b are close to or away from each other.

[0048] like Figures 2 to 5 As shown, the assembly mechanism 10 further includes a mounting plate 31, which is fixed to a support plate 32. The mounting plate 31 extends along a first direction L1 and can be perpendicular to a second direction L2. The first clamping member 2a and the second clamping member 2b can abut against the same side of the mounting plate 31. Two mounting members 5 are fixed to one side of the mounting plate 31. The mounting members 5 have through-holes extending therethrough. The two ends of the bidirectional screw 11 extend through the two through-holes. The two mounting members 5 respectively support the ends of the bidirectional screw 11, allowing the bidirectional screw 11 to rotate relative to the mounting members 5. Optionally, the mounting members 5 can be bearing seats.

[0049] like Figure 3As shown, the first clamping member 2a includes a first extension portion 21a and a first connecting portion 22a connected to each other. The first extension portion 21a and the first connecting portion 22a are both plate-shaped. The first connecting portion 22a can extend in the second direction L2 and can be perpendicular to the first direction L1. The first connecting portion 22a has a first connecting hole. The second clamping member 2b includes a second extension portion 21b and a second connecting portion 22b connected to each other. The second extension portion 21b and the second connecting portion 22b are both plate-shaped. The second connecting portion 22b can extend in the second direction L2 and can be perpendicular to the first direction L1. The second connecting portion 22b has a second connecting hole. The bidirectional screw 11 passes through the first and second connecting holes and is threadedly connected to the walls of the first and second connecting holes. When the bidirectional screw 11 rotates, the first and second connecting portions 22a and 22b move along the bidirectional screw 11. The first extension portion 21a and the second extension portion 21b abut against the side of the mounting plate 31 facing away from the drive assembly 1. The first extension portion 21a and the second extension portion 21b are used to abut against the mounting bracket 72. The first extension portion 21a and the second extension portion 21b cooperate to clamp the mounting bracket 72. Optionally, the first extension portion 21a and the first connecting portion 22a may be integrally formed, and the second extension portion 21b and the second connecting portion 22b may be integrally formed.

[0050] Furthermore, the mounting plate 31 is provided with a first guide opening 311 and a second guide opening 312, the first connecting portion 22a passes through the first guide opening 311 and is connected to the bidirectional screw 11 on the other side of the mounting plate 31, and the second connecting portion 22b passes through the second guide opening 312 and is connected to the bidirectional screw 11 on the other side of the mounting plate 31, thereby realizing the connection between the first clamping member 2a and the second clamping member 2b and the bidirectional screw 11.

[0051] Optionally, the form of the driving component 1 is not limited to this. For example, the driving component 1 can only drive the first clamping member 2a or the second clamping member 2b to move. At this time, the driving component 1 can include a one-way screw and a driving motor 12, wherein one of the first clamping member 2a and the second clamping member 2b is set on the one-way screw, and the other of the first clamping member 2a and the second clamping member 2b can be fixed on the mounting plate 31. By rotating the one-way screw, the first clamping member 2a or the second clamping member 2b set on the one-way screw can be driven to move along the first direction L1, so that the first clamping member 2a and the second clamping member 2b are closer to or farther away from each other, thereby realizing the clamping or release of the mounting bracket 72 supported on the support plate 32.

[0052] In the embodiments of the present application, Figure 2 and Figure 4As shown, the battery cell assembly system also includes a support frame 4, which can be placed on the floor of the assembly workshop where the battery cell assembly system is located. The support frame 4 can include a support plate 41 and four support rods 42. The four support rods 42 extend along the third direction L3 and are connected to the lower surface of the support plate 41. The support rods 42 are placed on the floor of the assembly workshop to support the support plate 41. The upper surface of the support plate 41 is a support surface 411, and the support plate 32 is placed on the support surface 411, so that the support plate 41 can support the entire assembly mechanism 10.

[0053] Optionally, the assembly mechanism 10 further includes an anti-slip pad 33, which is fixed to the side of the support plate 32 facing the support frame 4. The anti-slip pad 33 is in contact with the support surface 411. The provision of the anti-slip pad 33 can improve the stability of the assembly mechanism 10 when placed on the support frame 4. Preferably, the anti-slip pad 33 is a rubber pad.

[0054] like Figure 3 、 Figure 6 and Figure 7 As shown, the assembly mechanism 10 also includes a first guide assembly 6a and a second guide assembly 6b, the first guide assembly 6a includes a first fixed member 61a and a first movable member 62a, the first fixed member 61a offers a first guide hole 611a, the first guide hole 611a runs through the first fixed member 61a along a first direction L1, and the first movable member 62a is partially located in the first guide hole 611a and can slide in the first guide hole 611a. The second guide assembly 6b includes a second fixed member 61b and a second movable member 62b, the second fixed member 61b offers a second guide hole 611b, the second guide hole 611b runs through the second fixed member 61b along the first direction L1, and the second movable member 62b is partially located in the second guide hole 611b and can slide in the second guide hole 611b. The first movable member 62a is connected to the first clamping member 2a, and the second movable member 62b is connected to the second clamping member 2b. In this way, the first fixed member 61a can guide the movement of the first movable member 62a, and thus the movement of the first clamping member 2a, while the second fixed member 61b can guide the movement of the second movable member 62b, and thus the movement of the second clamping member 2b. This improves the stability of the movement of the first clamping member 2a and the second clamping member 2b.

[0055] Alternatively, the quantity of the first moving member 62a that the first guide assembly 6a comprises and the quantity of the second moving member 62b that the second guide assembly 6b comprises can be selected according to demand, for example, the quantity of the first moving member 62a can be one, two, four or more.The quantity of the second moving member 62b can be one, two, four or more, and offers the guide hole identical with the first moving member 62a quantity on the first fixed member 61a, and each first guide hole 611a is all correspondingly provided with the first moving member 62a. Offer the guide hole identical with the second moving member 62b quantity on the second fixed member 61b, and each second guide hole 611b is all correspondingly provided with the second moving member 62b.Preferably, the quantity of the first moving member 62a and the second moving member 62b is four.

[0056] Further, the first clamping member 2a and the second clamping member 2b are between the first fixing member 61a and the second fixing member 61b, and the first moving member 62a and the second moving member 62b are connected with the both sides of the first clamping member 2a and the second clamping member 2b opposite to each other respectively.Like this, the first moving member 62a and the second moving member 62b can not take the space between the first clamping member 2a and the second clamping member 2b, can avoid the first moving member 62a and the second moving member 62b and the mounting bracket 72 from interfering.

[0057] In addition, the first moving part 62a includes a first limiting portion 621a and a first moving portion 622a, one end of the first moving portion 622a is connected to the first clamping member 2a, and the other end of the first moving portion 622a is connected to the first limiting portion 621a, and part of the first extension portion 21a is located in the first guide hole 611a. By moving the first extension portion 21a in the first guide hole 611a, the movement of the first moving part 62a can be guided, and then the movement of the first clamping member 2a can be guided. The second movable member 62b includes a second limiting portion 621b and a second movable portion 622b, one end of the second movable portion 622b is connected to the second clamping member 2b, and the other end of the second movable portion 622b is connected to the second limiting portion 621b. Part of the second extension portion 21b is located in the second guide hole 611b. By moving the second extension portion 21b in the second guide hole 611b, the movement of the second movable member 62b can be guided, and then the movement of the second clamping member 2b can be guided.

[0058] At least part of the orthographic projection of the first limiting portion 621a on the first fixing member 61a is located outside the first guide hole 611a, and at least part of the orthographic projection of the second limiting portion 621b on the second fixing member 61b is located outside the second guide hole 611b. This prevents the first limiting portion 621a from passing through the first guide hole 611a, and the second limiting portion 621b from passing through the second guide hole 611b. When the first limiting portion 621a abuts the first fixing member 61a, the first moving member 62a and the first clamping member 2a cannot continue to move, thereby limiting the position of the first clamping member 2a. When the second limiting portion 621b abuts the second fixing member 61b, the second moving member 62b and the second clamping member 2b cannot continue to move, thereby limiting the position of the second clamping member 2b.

[0059] like Figure 3 As shown, the first movable member 62a and the second movable member 62b are both T-shaped rods. At this time, the first limiting portion 621a and the first movable portion 622a are both cylindrical, and the first limiting portion 621a and the first movable portion 622a are integrally formed. The axis of the first limiting portion 621a coincides with the axis of the first movable portion 622a, and the axis of the first limiting portion 621a and the first connecting portion 22a both extend along the first direction L1. The diameter of the first limiting portion 621a is larger than the diameter of the first guide hole 611a, so that the first limiting portion 621a can limit the movement of the first movable member 62a. The second limiting portion 621b and the second movable portion 622b are integrally formed, the axis of the second limiting portion 621b coincides with the axis of the second movable portion 622b, and the axis of the second limiting portion 621b and the second connecting portion 22b both extend along the second direction L2, and the diameter of the second limiting portion 621b is greater than the diameter of the second guide hole 611b, so that the second limiting portion 621b can limit the movement of the second movable member 62b.

[0060] Optionally, the forms of the first moving member 62a and the second moving member 62b are not limited to this. For example, the first moving portion 622a and the second moving portion 622b are cylindrical, and the first limiting portion 621a and the second limiting portion 621b can be cylindrical or rectangular. Part of the first limiting portion 621a is offset relative to the first guide hole 611a, and part of the second limiting portion 621b is offset relative to the second guide hole 611b, so that the first limiting portion 621a cannot pass through the first guide hole 611a, and the second limiting portion 621b cannot pass through the second guide hole 611b, thereby achieving the limitation of the first moving member 62a and the second moving member 62b.

[0061] When using the battery cell assembly system of the present application to assemble battery cells 71, first place the first mounting bracket 72 between the first clamping member 2a and the second clamping member 2b, then drive the bidirectional screw 11 to rotate by the drive motor 12 to drive the first clamping member 2a and the second clamping member 2b to move, so that the first clamping member 2a and the second clamping member 2b clamp the mounting bracket 72 from the opposite ends of the first mounting bracket 72. Then, the multiple battery cells 71 on the conveying mechanism 8 are correspondingly loaded into the mounting holes on the first mounting bracket 72 by the conveying mechanism 9, thereby completing the installation of the first mounting bracket 72. Then, insert the second mounting bracket 72 between the first clamping member 2a and the second clamping member 2b. At this time, the multiple mounting holes on the second mounting bracket 72 are respectively aligned with the multiple battery cells 71. Then, press the second mounting bracket 72 downward to put the second mounting bracket 72 on the top of the multiple battery cells 71.
