[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0041] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0042] See Figure 1 and Figure 2This application provides a battery cell stacking device, including: a first base 100 having a first direction Z and a second direction X, wherein the line containing the first direction Z is perpendicular to the line containing the second direction X; a second base 200 disposed outside the first base 100, wherein in the first direction Z, the second working surface of the second base 200 is higher than the first working surface of the first base 100; a first stacking assembly 300 movably disposed on the first working surface and reciprocating along the second direction X; and a second stacking assembly 400 movably disposed on the second working surface and reciprocating along the second direction X, wherein the second stacking assembly 400 is located above the first stacking assembly 300.

[0043] In this embodiment, the first base 100 is used to support the first stacking component 300, and the second base 200 is used to support the second stacking component 400. The second stacking component 400 is placed above the first stacking component 300. In this way, the space utilization of the cell stacking device 30 is improved at least in the first direction Z, the efficiency of cell stacking is improved, and the cost is reduced.

[0044] Specifically, the cell stacking device 30 is configured as a combination of at least a first base 100, a second base 200, a first stacking assembly 300, and a second stacking assembly 400. The first base 100 can be a support frame, which is set on the ground to provide the first stacking assembly 300 with height along the first direction Z, facilitating subsequent cell stacking operations. The first working surface is the top surface of the first base 100, which is positioned opposite to the ground. The second base 200 can be a bracket, which is set on the ground close to the first base 100 to improve the compactness of the cell stacking device 30 layout and the ease of cooperation between the second stacking assembly 400 and the first stacking assembly 300. The second working surface is the top surface of the second base 200, which is positioned opposite to the ground. The first stacking assembly 300 is provided with a first set of slots for horizontally stacking cells. Each set of first slots can realize the horizontal stacking of multiple cells, thus, the first stacking assembly 300 can simultaneously realize the horizontal stacking of multiple sets of cell modules. The second stacking assembly 400 is provided with a second set of slots for horizontally stacking battery cells. Each set of second slots can realize the horizontal stacking of multiple battery cells. In this way, multiple sets of battery cell modules can be horizontally stacked simultaneously through the second stacking assembly 400. The first stacking assembly 300 and the second stacking assembly 400 can reciprocate in the same direction. In this way, the loading end and unloading end of the battery cell stacking equipment 30 can be shared to realize continuous horizontal stacking of battery cell modules and improve battery cell stacking efficiency. For example, the first stacking component 300 is first placed on the loading end of the cell stacking device 30 for loading. At this time, the second stacking component 400 can be located at the unloading end of the cell stacking device 30 to form a clearance space above the first stacking component 300, which facilitates the stacking of cells on the first stacking component 300. After the cells on the first stacking component 300 are stacked, the first stacking component 300 can be moved to the unloading end for unloading, and at the same time, the second stacking component 400 can be moved to the loading end for loading. In this way, through the staggered spatial arrangement, the purpose of loading and unloading can be achieved simultaneously, thereby greatly improving the loading and unloading efficiency of the cell stacking device 30, improving the cell stacking efficiency, and reducing time costs.

[0045] It should be noted that the first direction Z can be a vertical direction perpendicular to the ground, and the second direction X can be a horizontal direction parallel to the ground.

[0046] like Figure 1 and Figure 2As shown, in one possible implementation, the first base 100 further has a third direction Y, the line containing the third direction Y is perpendicular to the line containing the first direction Z and the line containing the second direction X, the second base 200 includes a first support 210 and a second support 220, the first support 210 and the second support 220 are respectively disposed on opposite sides of the first base 100 along the third direction Y, and the second stacking assembly 400 is mounted on the first support 210 and the second support 220.

[0047] In this embodiment, the specific configuration of the second base 200 is optimized. Specifically, the second base 200 is configured as a combined component including at least a first support 210 and a second support 220. The first support 210 and the second support 220 can have the same shape and structure to facilitate processing. The first support 210 and the second support 220 are respectively close to the opposite sides of the first base 100 along the third direction Y. In this way, a pier extending along the second direction X is formed in the space above the first base 100, which facilitates the subsequent erection of the second stacking assembly 400. This allows the second stacking assembly 400 to overlap with the first stacking assembly 300, saving space and improving the space utilization rate in the first direction Z.

[0048] Of course, in other embodiments, the second base 200 can also be disposed on one side of the first base 100 to form a stepped distribution structure in parallel or side by side. In this case, the first stacking component 300 and the second stacking component 400 do not interfere with each other in the first direction Z, and it is not easy to make mistakes. Furthermore, by using the two stacking components alternately, loading and unloading can be completed simultaneously, and the stacking efficiency of the battery cells is high.

[0049] It should be noted that the first direction Z can be a vertical direction perpendicular to the ground. In this case, the second direction X can be a horizontal direction parallel to the ground, and the third direction Y can be a horizontal direction parallel to the ground. The line containing the third direction Y is perpendicular to the line containing the second direction X.

[0050] like Figure 3 As shown, in one possible implementation, the first stacking assembly 300 includes a support member 310, a pressing member 320, and a plurality of stacking channels 330. The support member 310 is movably disposed on the first base 100, and the stacking channels 330 are disposed on the side of the support member 310 away from the first base 100. The plurality of stacking channels 330 are distributed at intervals along the third direction Y of the first base 100. The pressing member 320 is movably disposed on the support member 310 to be close to or away from the plurality of stacking channels 330 in the second direction X.

[0051] In this embodiment, the specific configuration of the first stacking assembly 300 is optimized. Specifically, the first stacking assembly 300 is configured as a combination of at least a support member 310, a pressing member 320, and multiple stacking channels 330. The support member 310 can be a rectangular frame, movably disposed on the top of the first base 100 to provide support and a reference horizontal plane for the stacking channels 330. The multiple stacking channels 330 are arranged in rows or columns on the top surface of the support member 310 to achieve horizontal stacking of multiple battery cells, improving the stacking neatness and stacking effect of the multiple battery cells. The stacking channels 330 can extend along the second direction X to achieve stacking of multiple battery cells in this direction. The pressing member 320 can be a long strip extending along the third direction Y and covering the multiple stacking channels 330 in the third direction Y. In this way, the pressing member 320 can be driven to approach the multiple stacking channels 330 in the second direction X to simultaneously press and fasten the multiple battery cell groups within the multiple stacking channels 330, improving the pressing and fixing efficiency of the battery cell groups. The first stacking assembly 300 provided in this example shares a support member 310 and a pressing member 320, resulting in lower material costs, a more compact layout, and greater space utilization. Furthermore, it can simultaneously achieve horizontal stacking of multiple battery cell groups, resulting in high stacking efficiency.

[0052] Additionally, it should be noted that the specific configuration of the second stacking component 400 is the same as that of the first stacking component 300, and the specific composition of the second stacking component 400 will not be described in detail here.

[0053] like Figure 4 and Figure 5 As shown, in one possible implementation, the stacking channel 330 includes a loading platform 331, a reference block 332, and a clamping member 333. The loading platform 331 is disposed on the support member 310 and extends along the second direction X. The reference block 332 is disposed on the side of the loading platform 331 away from the support member 310 and is disposed opposite to the pressing member 320 in the second direction X. The clamping member 333 extends in the same direction as the loading platform 331 and can be close to or away from the loading platform 331 in the third direction Y.

[0054] In this embodiment, the specific configuration of the stacking channel 330 is optimized. Specifically, the stacking channel 330 is configured as a combination of at least a loading platform 331, a reference block 332, and a clamping member 333. The loading platform 331 can be an inverted U-shaped frame, including a carrier plate at the top and two support plates below the carrier plate. The top of the carrier plate is provided with two raised rails for storing and stacking multiple battery cells. The reference block 332 can be a U-shaped abutment block, which can be connected to one end of the carrier plate of the loading platform 331 by fasteners such as screws / bolts. In this way, it can cooperate with the pressing member 320 to press the stacked battery cells in the second direction X. The clamping member 333 can be a long plate structure, and two clamping members can be provided, located on opposite sides of the loading platform 331. At the same time, the two clamping members 333 are arranged adjacent to the reference block 332. The clamping members 333 can simultaneously clamp the sidewalls of multiple battery cells in the third direction Y. The stacking channel 330 provided in this example has a simple structure and flexible adjustment. It can clamp and fix multiple stacked cells simultaneously in at least two directions, with high clamping accuracy for cell groups, good horizontal stacking neatness, and good horizontal stacking effect.

[0055] In one example, the clamping member 333 is provided with urethane adhesive on the side facing the loading platform 331. This urethane adhesive can increase the tightness of the connection between the clamping member 333 and the corresponding battery cell, prevent slippage between the two, improve the clamping stability of the battery cell assembly, and at least improve the stacking accuracy and neatness of the battery cell assembly in the third direction Y, thereby improving the performance of the battery module.

[0056] like Figure 4 and Figure 5 As shown, in one possible implementation, the stacking channel 330 further includes a first track 334, a first slider 335, and a first drive member 336. The first track 334 extends along a third direction Y and is connected to the side of the loading platform 331 facing the support member 310. The clamping member 333 is slidably connected to the first track 334 via the first slider 335. The output end of the first drive member 336 is connected to the clamping member 333 and can drive the clamping member 333 to reciprocate along the first track 334.

[0057] In this embodiment, the specific configuration of the stacking channel 330 is further optimized. Specifically, the stacking channel 330 is configured as a combination of at least a loading platform 331, a reference block 332, a clamping member 333, a first track 334, a first slider 335, and a first driving member 336. The first track 334 can be a straight track, which can be connected to the bottom of the loading platform 331 by fasteners such as screws / bolts, and extends from the loading platform 331 at least in the third direction Y, so as to reserve sufficient clamping space in this direction to realize the clamping of cells of various sizes and improve the applicability of the stacking channel 330. The first slider 335 can be a rectangular block, which can be slidably fitted under the first track 334 through a groove structure and can reciprocate along the first track 334. The clamping member 333 can be connected to the outer wall of the first slider 335 by fasteners such as screws / bolts. In this way, the reciprocating movement of the first slider 335 on the first track 334 can move the clamping member 333 closer to or away from the loading platform 331, thereby clamping multiple battery cells stacked on the loading platform 331. The first driving member 336 can be a cylinder, and its cylinder seat can be connected to the loading platform 331 by fasteners such as screws / bolts. Its drive shaft is inserted into the connecting hole on the clamping member 333. In this way, the first driving member 336 can drive the first clamping member 333 to reciprocate in the third direction Y, improving the accuracy and reliability of movement. The stacking channel 330 provided in this example has a simple structure and compact fit, which can realize the clamping and fixing of multiple stacked battery cells in the third direction Y.

[0058] In one example, two clamping members 333 are provided, located on opposite sides of the long side of the loading platform 331. Two first driving members 336 are provided, with the output end of one first driving member 336 connected to one clamping member 333. This allows for independent driving of a single clamping member 333, improving the clamping and adjustment flexibility of the stacking channel 330. Furthermore, the dual-sided clamping also improves the clamping accuracy and stacking neatness of the stacking channel 330. Two first tracks 334 and four first sliders 335 are provided, with two first sliders 335 corresponding to each first track 334. The two ends of a clamping member 333 along the second direction X are slidably connected to the two first tracks 334 via a first slider 335. This improves the movement stability and smoothness of the clamping member 333, ensuring uniform pressure between the inner side of the clamping member 333 and the sidewalls of multiple battery cells, thus improving the clamping effect.

[0059] like Figure 4 and Figure 5 As shown, in one possible implementation, the stacking channel 330 further includes a buffer 337, which is disposed on the loading platform 331 and located between the loading platform 331 and the support member 310.

[0060] In this embodiment, the specific configuration of the stacking channel 330 is further optimized. Specifically, the stacking channel 330 is configured as a combination of at least a loading platform 331, a reference block 332, a clamping member 333, a first track 334, a first slider 335, a first driving member 336, and a buffer member 337. The buffer member 337 can be an elastic structure with a buffer pin head, which includes a connecting cylinder, an elastic member, and a buffer pin. One end of the connecting cylinder is open, and the opening faces the outside of the loading platform 331. A limit ring is provided inside the opening. The connecting cylinder extends along the third direction Y and can be connected to the connecting block. It is connected to the bottom of the loading platform 331 in conjunction with screws / bolts and other structures; the elastic element, which can be a spring or the like, is located inside the opening of the connecting cylinder to provide elastic buffering force to the buffer needle in the third direction Y; the buffer needle has abutting frustums at both ends, one abutting frustum is located inside the opening of the connecting cylinder, abutting against the elastic element and constrained by the limiting ring, and the other abutting frustum is located outside the connecting cylinder to abut against the inner wall of the clamping member 333, thereby adjusting the clamping length in the third direction Y. In this way, when switching cell lengths, compatibility can be achieved through the buffer member 337, improving the applicability of the stacking channel 330.

[0061] like Figure 3 As shown, in one possible implementation, the pressing member 320 has an adhesive layer 321 on the side facing the stacking channel 330. This configuration increases the tightness of the connection between the pressing member 320 and the corresponding battery cell through the adhesive layer 321, preventing slippage between the pressing member 320 and the battery cell during the pressing process, improving the stability and reliability of the pressing process, and at least improving the stacking accuracy and neatness of the battery cell assembly in the second direction X, thereby improving the performance of the battery module. For example, but not limited to, the adhesive layer 321 is urethane adhesive.

[0062] like Figure 1 and 3 As shown, in one possible implementation, the first stacking assembly 300 further includes a second track 340, a second slider 350, and a second drive member 360. The second track 340 is disposed on the support member 310 and extends along the second direction X. The pressing member 320 is slidably connected to the second track 340 through the second slider 350. The output end of the second drive member 360 is connected to the pressing member 320 and can drive the pressing member 320 to reciprocate along the second track 340.

[0063] In this embodiment, the specific configuration of the first stacking assembly 300 is further optimized. Specifically, the first stacking assembly 300 is configured as a combination of at least a support member 310, a pressing member 320, multiple stacking channels 330, a second track 340, a second slider 350, and a second drive member 360. The second track 340 can be a straight track, which can be connected to the support member 310 by welding or other means. Two tracks can be provided, and the two second tracks 340 can be located on the outside of the stacking channel 330 to reserve sufficient pressing space in the second direction X, so as to realize the pressing and fixing of battery cell groups with different stack numbers, thereby improving the stacking product range of the stacking channel 330. The second slider 350 can be a rectangular block, which can be slidably fitted onto the second track 340 via a groove structure and can reciprocate along the second track 340. The pressing component 320 can be welded to the top wall of the second slider 350, and its two ends are respectively connected to the two second tracks 340 via two second sliders 350. In this way, the reciprocating movement of the second slider 350 on the second track 340 can move the pressing component 320 closer to or further away from the stacking channel 330, thereby achieving the pressing and fixing of multiple stacked cells in the second direction X. The second driving component 360 can be a servo module, which is mounted on the support component 310 and can drive the second slider 350 to reciprocate along the second track 340 with high movement accuracy and good pressing effect. The first stacking assembly 300 provided in this example has a compact layout, occupies little space, and can realize the simultaneous pressing and fixing of multiple cell groups in the second direction X.

[0064] like Figure 3 , Figure 6 and Figure 7 As shown, in one possible implementation, it also includes a third track 510, a third slider 520 and a third drive member 530.
