[0063] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0064] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings are used only for the convenience of describing this utility model 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, and therefore should not be construed as a limitation of this utility model.

[0065] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0066] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0067] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0068] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0069] like Figures 1 to 7 As shown, this embodiment provides a grouped stacking assembly platform having a first direction X, a second direction Y, and a third direction Z that intersect each other in pairs.

[0070] In some implementations, the first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0071] In some implementation methods, please refer to Figure 1 The group stacking assembly platform includes an operating table 10, two sets of cell positioning mechanisms 20, two sets of cell centering clamping mechanisms 30, two sets of end plate positioning and pressing mechanisms 40, and a middle end plate positioning mechanism 90. The cell positioning mechanism 20, cell centering clamping mechanism 30, end plate positioning and pressing mechanism 40, and middle end plate positioning mechanism 90 are all integrated on the operating table 10, enabling a single production line to complete the stacking of 1A1B cells at one time, simplifying the process, improving operating efficiency, and avoiding space waste caused by setting up a separate production line.

[0072] For ease of description, the 1A1 B cell module 80 includes a first cell module 80a and a second cell module 80b. The purpose of this group stacking assembly platform is to press and bond the first cell module 80a, the second cell module 80b, the outer end plate 60, and the middle end plate 70 together to achieve one-time stacking of the 1A1 B cells. Each of the first cell module 80a and the second cell module 80b contains multiple individual cells.

[0073] In some embodiments, the cell positioning mechanism 20 is used to support the cell module 80 and perform initial positioning of the cell module 80 in the second direction Y. Since the first cell module 80a and the second cell module 80b need to be pressed and stacked simultaneously, the cell positioning mechanism 20 is divided into two sets. The two sets of cell positioning mechanisms 20 are spaced apart on the operating table 10 along the second direction Y. One set of cell positioning mechanisms 20 is used to support the first cell module 80a and clamp the first cell module 80a on one side of the second direction Y, and the other set of cell positioning mechanisms 20 is used to support the second cell module 80b and clamp the second cell module 80b on one side of the second direction Y.

[0074] In some embodiments, two sets of cell centering clamping mechanisms 30 are respectively connected to the operating table 10. The two sets of cell centering clamping mechanisms 30 are spaced apart along the first direction X, and are used to clamp the first cell module 80a and the second cell module 80b on both sides of the first cell module 80b in the first direction X. Two sets of end plate positioning and clamping mechanisms 40 are respectively connected to the operating table 10. The two sets of end plate positioning and clamping mechanisms 40 are spaced apart along the second direction Y, and are located between the two sets of end plate positioning and clamping mechanisms 40. The end plate positioning and clamping mechanisms 40 are used to clamp the outer end plate 6. 0; The mid-end plate positioning mechanism 90 is connected to the operating table 10. The mid-end plate positioning mechanism 90 is located between the two sets of end plate positioning and pressing mechanisms 40. The mid-end plate positioning mechanism 90 and the two sets of end plate positioning and pressing mechanisms 40 form two spaces for placing the first battery cell module 80a and the second battery cell module 80b respectively. The mid-end plate positioning mechanism 90 is used to fix the mid-end plate 70. Thus, under the action of the end plate positioning and pressing mechanism 40, the outer end plate 60, the first battery cell module 80a, the mid-end plate 70, the second battery cell module 80b, and the outer end plate 60 can be pressed into a group in one go, simplifying the stacking process.

[0075] In some embodiments, the cell centering clamping mechanism 30 is connected to the operating table 10. Two sets of cell centering clamping mechanisms 30 are opposite each other along the first direction X and are respectively disposed on both sides of the cell positioning mechanism 20. The cell centering clamping mechanism 30 is used to clamp the cell module 80 in the first direction X. Two sets of end plate positioning and pressing mechanisms 40 are opposite each other along the second direction Y and are respectively disposed at both ends of the cell positioning mechanism 20. They are used to press the cell module 80 in the second direction Y. Thus, during operation, the cell module 80 is placed on the cell positioning mechanism 20. After 0, the cell positioning mechanism 20 can support and initially position the cell module 80. The end plate positioning and pressing mechanism 40 positions and fixes the outer end plate 60, and the middle end plate positioning mechanism 90 positions and fixes the middle end plate 70. Then, the cell centering clamping mechanism 30 clamps the first cell module 80a and the second cell module 80b from the first direction X. The end plate positioning and pressing mechanism 40 presses the outer end plate 60, the first cell module 80a, the second cell module 80b and the middle end plate 70 from the second direction Y, completing the stacking of the 1A1B cell modules. This achieves one-time stacking and simplifies the stacking process. Integrating all components into one unit can avoid space waste caused by adding production lines and reduce investment costs.

[0076] In some implementation methods, please refer to Figure 3The cell positioning mechanism 20 includes a floating platform 21 and a support platform 22. The support platform 22 is used to support the first cell module 80a or the second cell module 80b. The floating platform 21 is movably connected to the operating table 10, and the floating platform 21 can move along the second direction Y to approach or move away from the mid-end plate positioning mechanism 90. The support platform 22 is located on the floating platform 21. Specifically, the operating table 10 is provided with a first slide rail 212 extending along the second direction Y, and the floating platform 21 is provided with a first slider 211. The first slider 211 slides in cooperation with the first slide rail 212. Thus, the floating platform 21 can drive the support platform 22 to move synchronously along the second direction Y, so that the cell module 80 can quickly approach the mid-end plate 70 during the centering and pressing process, thereby improving the efficiency of group stacking.

[0077] In the above embodiments, it should be noted that the power source for driving the floating platform 21 to move along the second direction Y can be realized through a drive structure, such as a cylinder or a linear motor; or it can be driven by the friction between the battery cell module 80 and the support platform 22, which simultaneously drives the floating platform 21 to move during the process of the battery cell centering clamping mechanism 30 and the end plate positioning and pressing mechanism 40 applying force to the battery cell module 80.

[0078] In some implementation methods, please refer to Figure 3 and Figure 4 To achieve the positioning of the battery cell module 80 in the second direction Y, the battery cell positioning mechanism 20 further includes a support plate 23, a first driving member 24, a second driving member 25a, and a pre-pressing member 25. The support plate 23 is connected to the floating platform 21 and extends along the third direction Z. The height of the support plate 23 is lower than the height of the floating platform 21. The first driving member 24 is located on the support plate 23. The second driving member 25a is located at the output end of the first driving member 24, and the first driving member 24 can drive the second driving member 25a to move along the second direction Y. The pre-pressing member 25 is located at the output end of the second driving member 25a, and the second driving member 25a can drive the pre-pressing member 25 to move along the third direction Z. Specifically, the support platform 22 has a window 22a extending along the second direction Y, and the second driving member 25a can drive at least a portion of the pre-pressing member 25 to pass through the window 22a along the third direction Z.

[0079] Furthermore, the cell positioning mechanism 20 also includes a preliminary positioning reference 28 and two third driving members 29. The two third driving members 29 are respectively located at both ends of the middle plate positioning mechanism 90 in the second direction Y, and the third driving members 29 are connected to the operating table 10. The preliminary positioning reference 28 is located at the output end of the third driving member 29. The third driving member 29 can drive the preliminary positioning reference 28 to move along the third direction Z. The preliminary positioning reference 28 and the pre-pressing member 25 are used to jointly clamp the first cell module 80a or the second cell module 80b in the second direction Y. Thus, during the positioning process of the battery cell module 80, taking the second battery cell module 80b as an example, the third driving member 29 drives the initial positioning reference member 28 to rise along the third direction Z, and the first driving member 24 drives the pre-pressing member 25 to move away from the middle end plate 70 along the second direction Y until the pre-pressing member 25 moves to the end of the second battery cell module 80b away from the middle end plate 70. The second driving member 25a drives the pre-pressing member 25 to rise along the third direction Z to the window 22a, so that at least a part of the first driving member 24 can be opposite to the second battery cell module 80b in the second direction Y. At this time, the first driving member 24 drives the pre-pressing member 25 to press the second battery cell module 80b along the second direction Y until the second battery cell module 80b is in contact with and pressed against the initial positioning reference member 28 in the second direction Y, thereby realizing the positioning of the second battery cell module 80b.

[0080] In some implementations, the cell centering clamping mechanism 30 is connected to the floating stage 21 to ensure that the cell centering clamping mechanism 30 can move synchronously with the floating stage 21, thus ensuring the accuracy of subsequent centering clamping of the second cell module 80b.

[0081] In some implementations, such as Figure 4 As shown, the cell positioning mechanism 20 also includes two first limiters 27, both of which are mounted on the operating table 10. The two first limiters 27 are respectively located on both sides of the floating platform 21 in the second direction Y. The first limiters 27 are used to limit the floating platform 21 in the second direction Y. The first limiters 27 can prevent the floating platform 21 from traveling too far in the second direction Y, thus preventing overvoltage and avoiding damage to the cell module 80.

[0082] In some embodiments, during the process of the pre-compression member 25 acting on the cell module 80, in order to prevent the cell module 80 from falling off, the operating table 10 is also provided with a plurality of side plate limiting members 26 spaced apart along the second direction Y, so as to install the side plate 50 before clamping the cell module 80. The side plate 50, the outer end plate 60 and the middle end plate 70 are used together to form a station for placing the first cell module 80a and the second cell module 80b, so as to ensure the safety of the cell module 80 during the stacking process.

[0083] It should be noted that the two sets of cell centering clamping mechanisms 30 are located on both sides of the support platform 22 in the first direction X. Each set of cell centering clamping mechanisms 30 includes two cell centering clamping units spaced apart in the second direction Y. One cell centering clamping unit corresponds to the first cell module 80a, and the other cell centering clamping unit corresponds to the second cell module 80b. The cell centering clamping mechanism 30 is located inside the side plate 50 to avoid interference between the cell module 80 and the side plate 50 during the clamping process.

[0084] In some implementation methods, please refer to Figure 5 After the battery cell module 80 is positioned, a force needs to be applied to the battery cell module 80 in the first direction X to center and align multiple individual battery cells. The battery cell centering clamping mechanism 30 includes a fourth driving member 33, a mounting frame 31, a battery cell reference member 32, and a fifth driving member 34. The fourth driving member 33 is connected to the floating platform 21. The mounting frame 31 is provided with the output end of the fourth driving member 33, which can drive the mounting frame 31 to move along the first direction X. The battery cell reference member 32 is movably connected to the mounting frame 31 and is used to clamp the first battery cell module 80a and the second battery cell module 80b in the first direction X. The fifth driving member 34 is located on the battery cell reference member 32, and the output end of the fifth driving member 34 is connected to the mounting frame 31. The fifth driving member 34 is used to drive the battery cell reference member 32 to move along the third direction Z. Thus, the fifth driving member 34 drives the cell reference member 32 to rise along the third direction Z, so that the cell reference member 32 is opposite to the second cell module 80b in the first direction X. The fourth driving member 33 drives the cell reference member 32 to move closer to the second cell module 80b along the first direction X through the driving mounting bracket 31 and presses it against the second cell module 80b, so that multiple individual cells are centered and aligned.

[0085] In some embodiments, to prevent the cell reference component 32 from causing overvoltage and damaging the cell module 80, the cell centering clamping mechanism 30 further includes a second limiter 35 and a limit block 36. The second limiter 35 is mounted on the mounting bracket 31, and the limit block 36 is mounted on the floating platform 21. The second limiter 35 and the limit block 36 are positioned opposite each other in the first direction X. Thus, the second limiter 35 and the limit block 36 can prevent overvoltage and avoid damage to the cell module 80.

[0086] In some embodiments, to ensure the balance and stability of the cell reference component 32 as it moves up and down along the third direction Z, a guide structure can be provided between the cell reference component 32 and the mounting frame 31. For example, a guide groove 32a extending along the third direction Z can be provided on the cell reference component 32, and a guide block (not shown) that cooperates with the guide groove 32a can be provided on the mounting frame 31. The cooperation between the guide block and the guide groove 32a can ensure the balance and stability of the cell reference component 32.

[0087] In some implementation methods, please refer to Figure 6 The end plate positioning and pressing mechanism 40 includes an end plate pressing mechanism 42. Specifically, the end plate pressing mechanism 42 includes a sixth driving member 421 and an end plate reference member 422. The sixth driving member 421 is located on the operating table 10, and the end plate reference member 422 is used to support the outer end plate 60. The end plate reference member 422 is located at the output end of the sixth driving member 421. After the outer end plate 60 and the end plate reference member 422 cooperate, the sixth driving member 421 can drive the end plate reference member 422 to move along the second direction Y, thereby pushing the outer end plate 60 to press the cell module 80 along the second direction Y, so that the cell module 80 is attached to the middle end plate 70, thereby completing the stacking of the cell module 80.

[0088] In some embodiments, in order to ensure that the outer end plate 60 can be aligned and fitted with the cell module 80, the end plate positioning and clamping mechanism 40 further includes an end plate centering positioning mechanism 41. There are two end plate centering positioning mechanisms 41, which are respectively located on both sides of the end plate reference member 422 in the first direction X. The outer end plate 60 is centered and calibrated by using the end plate centering positioning mechanism 41.

[0089] In some embodiments, to ensure a stable fit between the outer end plate 60 and the end plate reference member 422, the end plate reference member 422 is provided with a limiting step 423. The outer end plate 60 engages with the limiting step 423. In addition, the end plate clamping mechanism 42 also includes a seventh driving member 427 and a clamping member 428. The seventh driving member 427 is connected to the end plate reference member 422, and the clamping member 428 is located at the output end of the seventh driving member 427. The seventh driving member 427 can drive the clamping member 428 to move along the second direction Y. The clamping member 428 is used to clamp the outer end plate 60 when it is opposite to the limiting step 423 in the third direction Z. The sixth driving member 421 can drive the outer end plate 60 to move along the second direction Y to clamp the first battery cell module 80a or the second battery cell module 80b, preventing the outer end plate 60 from falling or shifting during movement, and ensuring the clamping accuracy between the outer end plate 60 and the battery cell module 80.

[0090] In some embodiments, since the outer end plate 60 can move along the second direction Y under the drive of the sixth driving member 421, in order to ensure that the clamping member 428 can always cooperate with the limiting step 423 to fix the outer end plate 60, the end plate positioning and clamping mechanism 40 also includes a mounting plate 424, a second slide rail 425 and a second slider 426. The mounting plate 424 is connected to the end plate reference member 422, the seventh driving member 427 is disposed on the mounting plate 424, the second slide rail 425 extends along the second direction Y and is disposed on the mounting plate 424, the second slider 426 is slidably connected to the second slide rail 425 and is connected to the operating table 10; in this way, the seventh driving member 427 always moves synchronously with the end plate reference member 422 in the second direction Y, and after the mounting plate 424 pushes out the clamping member 428, it can ensure that the clamping member 428 and the end plate reference member 422 are relatively stationary, so that the outer end plate 60 can always be locked during the pressing process of the outer end plate 60 against the cell module 80.

[0091] In some implementations, such as Figure 7 As shown, the mid-end plate positioning mechanism 90 includes a positioning element 91 and a positioning pin 92. The positioning element 91 is connected to the operating table 10, and the positioning pin 92 is located on the positioning element 91. There are at least two positioning pins 92 so that the mid-end plate 70 can be installed on the positioning element 91 along the third direction Z through the positioning pins 92. Moreover, multiple positioning pins 92 can restrict the rotation of the mid-end plate 70 and ensure the pressing accuracy between the mid-end plate 70 and the battery cell module 80.

[0092] The working process of this utility model is as follows: Please refer to... Figures 1 to 7When the battery cells are stacked into groups, the side plate 50 is installed on the side plate limiting member 26, the middle end plate 70 is installed on the positioning member 91 through the positioning pin 92, the outer end plate 60 is engaged with the limiting step 423 of the end plate reference member 422, and after the outer end plate 60 is centered and corrected by the end plate centering positioning mechanism 41, the outer end plate 60 is locked by the clamping member 428 driven by the seventh driving member 427. The first battery cell module 80a and the second battery cell module 80b are placed on the two sets of battery cell positioning mechanisms 20 respectively. For ease of understanding, the second battery cell module 80b is taken as an example. The third driving member 29 drives the initial... The positioning reference member 28 rises along the third direction Z. The first driving member 24 drives the pre-pressing member 25 to move along the second direction Y away from the middle end plate 70 until the pre-pressing member 25 moves to the end of the second cell module 80b away from the middle end plate 70. The second driving member 25a drives the pre-pressing member 25 to rise along the third direction Z to the window 22a, so that at least a part of the first driving member 24 can be opposite the second cell module 80b in the second direction Y. At this time, the first driving member 24 drives the pre-pressing member 25 to press the second cell module 80b along the second direction Y until the second cell module 80b is... In the second direction Y, the initial positioning reference 28 is pressed and adhered to. Then, the fifth driving component 34 drives the cell reference 32 to rise in the third direction Z, so that the cell reference 32 is opposite to the second cell module 80b in the first direction X. The fourth driving component 33 drives the cell reference 32 to move closer to the second cell module 80b in the first direction X and press and adhere to the second cell module 80b through the driving mounting bracket 31, so that the second cell module 80b is centered and aligned. The third driving component 29 drives the initial positioning reference 28 to descend and retract in the third direction Z. The second driving component 25a drives the pre-compression component 2. 5. The device descends and retracts along the third direction Z. Then, the sixth driving component 421 drives the end plate reference component 422 to move along the second direction Y, pushing the outer end plate 60 to press the second cell module 80b along the second direction Y, so that the second cell module 80b is attached to the middle end plate 70, thereby completing the stacking of the second cell module 80b. The stacking process of the first cell module 80a is the same as that of the second cell module 80b. Thus, the outer end plate 60, the first cell module 80a, the middle end plate 70, the second cell module 80b and the outer end plate 60 can be pressed and attached from the second direction Y to complete the 1A1B cell stacking, realize one-time molding and simplify the stacking process.

[0093] In summary, this utility model embodiment provides a group stacking assembly platform, which integrates a cell positioning mechanism 20, a cell centering clamping mechanism 30, an end plate positioning and pressing mechanism 40, and a middle end plate positioning mechanism 90 on the operating table 10. During operation, after the cell module 80 is placed in the cell positioning mechanism 20, the cell positioning mechanism 20 can support and initially position the cell module 80. The end plate positioning and pressing mechanism 40 positions and fixes the outer end plate 60, and the middle end plate positioning mechanism 90 positions and fixes the middle end plate 70. Then, the cell centering clamping mechanism 30 clamps the first cell module 80a and the second cell module 80b from the first direction X, and the end plate positioning and pressing mechanism 40 presses the outer end plate 60, the first cell module 80a, the second cell module 80b, and the middle end plate 70 from the second direction Y, thus completing 1A1. The stacking of B-cell modules enables one-time stacking, simplifying the stacking process. Furthermore, integrating all components into one unit avoids space waste caused by adding production lines and reduces investment costs.
