Technical Field

[0001] This application relates to the field of battery technology, and in particular to a cell stacking device and a battery assembly system. Background Technology

[0002] With the development of new energy technologies, the demand for portable power banks has increased dramatically. In particular, lithium batteries have attracted much market attention due to their advantages such as high energy density, high operating voltage, good storage performance, and long lifespan. In actual packaging, operators need to stack several battery cells into battery modules of different sizes and capacities for use in mobile devices.

[0003] In related technologies, to improve stacking convenience, a sloping stacking mechanism is generally used to stack multiple battery cells at an angle. However, traditional sloping stacking mechanisms occupy a large space and can generally only achieve the sloping stacking of one or at most two battery modules, resulting in low space utilization and high cost.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] See Figure 1 This application provides a battery cell stacking device, including: a base 100; a rotating mechanism 200 disposed above the base 100, the rotating mechanism 200 being rotatable about the line containing the height direction Z; a polyhedral support 300 connected above the rotating mechanism 200, the polyhedral support 300 having multiple working surfaces continuously distributed in the circumferential direction, the working surfaces being set at acute angles to the line containing the height direction Z; and multiple stacking components 400 disposed on the outer periphery of the polyhedral support 300, one stacking component 400 being correspondingly disposed on one working surface.

[0041] In this embodiment, the polyhedral support 300 is rotatably mounted above the base 100 by the rotating mechanism 200. At the same time, multiple working surfaces are arranged in the circumferential direction of the polyhedral support 300, and a stacking component 400 is set on each working surface. In this way, the space utilization of the cell stacking device 30 is improved at least in the circumferential direction of the polyhedral support 300, the stacking efficiency of the cell group is improved, and the cost is reduced.

[0042] Specifically, the cell stacking equipment 30 is configured as a combination of at least a base 100, a rotating mechanism 200, a polyhedral support 300, and multiple stacking components 400. The base 100 can be a square base, which provides support for the rotating mechanism 200, the polyhedral support 300, and the multiple stacking components 400, and provides vertical height for the stacking components 400 to facilitate subsequent cell stacking operations. The rotating mechanism 200 is rotatably mounted on top of the base 100, allowing the polyhedral support 300 to rotate around the height direction Z, thereby enabling tilted stacking of multiple stacking components 400 at the same position, improving the stacking efficiency and yield of the cell assembly. The polyhedral support 300 can be a near-roof structure, which can be a hexahedral structure, with its peripheral sides surrounding the top and bottom surfaces. The bottom surface dimension is larger than the top surface dimension, and the peripheral sides encompass four outer inclined surfaces, each of which is a working surface. The stacking assembly 400 is tilted on the working surface and has multiple slots for tilting and stacking battery cells. Each slot can achieve tilted stacking of one battery cell group. Thus, multiple battery cell groups can be tilted and stacked simultaneously using the stacking assembly 400 on one working surface, resulting in high efficiency. It should be noted that the "height direction Z" mentioned in this example refers to the direction perpendicular to the ground.

[0043] like Figures 2 to 4 As shown, in one possible embodiment, the rotating mechanism 200 includes a drive assembly 210, a first connector 220, and a positioning assembly 230. The drive assembly 210 is disposed on the base 100, the first connector 220 is disposed at the output end of the drive assembly 210 and is located above the base 100; the positioning assembly 230 is disposed on the base 100 and is located outside the first connector 220. The positioning assembly 230 is used to limit the position of the first connector 220 in the circumferential direction, and the polyhedral support 300 is disposed on the side of the first connector 220 away from the base 100.

[0044] In this embodiment, the specific configuration of the rotating mechanism 200 is optimized. Specifically, the rotating mechanism 200 is configured as a combination of at least a drive component 210, a first connector 220, and a positioning component 230. The drive component 210 can be a gear meshing structure or a turntable structure, which is mounted on the base 100 and at least partially hidden inside the base 100 to improve aesthetics. The first connector 220 can be a plate-like structure, which can be connected to the output end of the drive component 210 by fasteners such as screws / bolts, so that it can be driven by the drive component 210 to rotate around the line of height direction Z, thereby realizing the rotation of the polyhedral support 300. Weight reduction holes can be provided in the middle region of the first connector 220 to reduce the output power of the drive component 210 and reduce energy consumption. The positioning component 230 can be a cylinder or motor driven structure, which is used to limit the first connector 220 from continuing to rotate, thereby improving the rotation accuracy of the first connector 220. In addition, after the first connector 220 has rotated into place, it can fix it in a designated position, providing operators with a stable working environment for stacking battery cells on an inclined plane, thereby improving the stacking effect and stacking efficiency.

[0045] like Figures 2 to 4 As shown, in one possible implementation, the positioning component 230 includes a first driving member 231, a positioning member 232, and a limiting stop 233. The first driving member 231 is disposed on the base 100. The positioning member 232 is connected to the output end of the first driving member 231 and is disposed toward the first connecting member 220. The limiting stop 233 is disposed on the edge of the first connecting member 220. The first driving member 231 drives the positioning member 232 to move toward the first connecting member 220 and can stop the limiting stop 233.

[0046] In this embodiment, the specific configuration of the positioning component 230 is optimized. Specifically, the positioning component 230 is configured as a combination of at least a first driving member 231, a positioning member 232, and a limiting stop 233. The first driving member 231 can be a motor or a cylinder, which can be connected to the top of the base 100 by fasteners such as screws / bolts. The positioning member 232 can be a near-rectangular plate, which can be connected to the output end of the first driving member 231 and move with the first driving member 231. The limiting stop 233 can be a stop block, which can be welded to the edge of the first connecting member 220 facing the base 100. Two stops can be provided, and the two stops are spaced apart circumferentially along the first connecting member 220. Alternatively, the limiting stop 233 can be a stop post, which can be threaded into the edge of the first connecting member 220 and protrude toward the base 100. Two stops can be provided, and the two stops are spaced apart circumferentially along the first connecting member 220. In this way, when the first connecting piece 220 is rotated into position, the first driving piece 231 can be driven to drive the positioning piece 232 to be inserted into the two limit stops 233, thereby realizing the rotation stop and rotation positioning of the first connecting piece 220, improving the rotation accuracy and the stability of the working environment after rotation.

[0047] like Figures 2 to 6 As shown, in one possible implementation, the positioning component 230 further includes a first track 234, a first slider 235, and a second connector 236. The first track 234 is disposed on the base 100 and located between the first drive member 231 and the first connector 220. The first slider 235 is slidably connected to the side of the first track 234 away from the base 100. The second connector 236 is connected to the side of the first slider 235 away from the first track 234. The positioning member 232 is slidably connected to the second connector 236.

[0048] In this embodiment, the specific configuration of the positioning component 230 is further optimized. Specifically, the positioning component 230 is configured as a combination of at least a first driving member 231, a positioning member 232, a limiting stop member 233, a first track 234, a first slider 235, and a second connecting member 236. The first track 234 can be a straight track, which can be connected to the top of the base 100 by fasteners such as screws / bolts. Two first tracks 234 can be provided, distributed on both sides of the first driving member 231. The first slider 235 can be a rectangular block, which can slide on the top of the first track 234 through a groove structure and can reciprocate along the first track 234. The second connecting member 236 can be a long strip plate, whose two ends can be connected to the corresponding first slider 235 by fasteners such as screws / bolts. In this way, the second connecting member 236 can be mounted on the two first tracks 234, improving the movement stability and smoothness of the second connecting member 236. The top surface of the second connector 236 is provided with a groove that extends in the same direction as the first track 234. The positioning member 232 is slidably connected in the groove. In this way, the second connector 236 can provide a guiding function for the positioning member 232, and at the same time, it can also improve the stability of the moving environment of the positioning member 232.

[0049] like Figure 2 , Figure 5 and Figure 6 As shown, in one possible embodiment, the drive assembly 210 includes a second drive member 211, a gear 212, and a gear disk 213. The second drive member 211 is disposed on the base 100, the gear 212 is disposed on the output end of the second drive member 211, the gear disk 213 is disposed on the base 100 and meshes with the gear 212, and the first connecting member 220 is disposed on the side of the gear disk 213 away from the base 100.

[0050] In this embodiment, the specific configuration of the drive assembly 210 is optimized. Specifically, the drive assembly 210 is configured as a combination of at least a second drive member 211, a gear 212, and a gear disk 213. The second drive member 211 can be a rotary motor or a motor, which can be hidden in the internal cavity of the base 100 to improve the appearance. The output end of the second drive member 211 faces and extends out of the top surface of the base 100. The gear 212 is sleeved on the output end of the second drive member 211 and protrudes from the base 100. The gear disk 213 is rotatably connected to the base 100 through an annular bearing and meshes with the gear 212. In this way, the second drive member 211 can be driven to rotate, thereby driving the gear 212 to rotate, which in turn drives the gear disk 213 meshing with the gear 212 to rotate, which in turn drives the first connector 220 connected to the gear disk 213 to rotate, and drives the multi-faceted support 300 and the stacking assembly 400 connected to the first connector 220 to rotate, thereby realizing the stacking of cells in multiple directions. The drive component 210 provided in this example has high rotational stability and better rotational reliability.

[0051] like Figure 7 As shown, in one possible embodiment, the polyhedral support 300 includes an inner frame 310 and a plurality of outer frames 320. The inner frame 310 is disposed on the rotating mechanism 200, and the plurality of outer frames 320 are distributed at intervals along the circumference of the inner frame 310. The stacking assembly 400 is disposed on the side of the outer frames 320 away from the inner frame 310.

[0052] In this embodiment, the specific configuration of the polyhedral support 300 is optimized. Specifically, the polyhedral support 300 is configured as a combined component comprising at least an inner frame 310 and multiple outer frame bodies 320. The inner frame 310 can be a rectangular frame with a hollowed-out central area to reduce overall weight. Multiple reinforcing beams are designed in the central area to improve the structural stability and support of the inner frame 310. The bottom of the inner frame 310 can be connected to the first connector 220 using fasteners such as screws / bolts for easy disassembly and maintenance. The outer frame bodies 320 can be triangular frames with a hollowed-out central area to reduce weight. Reinforcing beams are provided at the hollowed-out areas to improve the structural stability and reliability of the outer frame bodies 320. The outer frame bodies 320 can be welded to the periphery of the inner frame body 310. The polyhedral support 300 provided in this example has an inner and outer frame structure 320. The outer frame 320 can be used to position the stacking assembly 400 outside the base 100, which is beneficial to improving the convenience of the inclined stacking operation of the battery cells. At the same time, the inner and outer structure layout is compact and the structure is stable, which can effectively reduce rotational interference.

[0053] like Figure 7As shown, in one possible embodiment, the outer frame 320 includes a base frame 321 and an inclined frame 322. The base frame 321 is located on the outer wall of the inner frame 310 near the base 100 and extends outward from the base 100. The inclined frame 322 is located above the base frame 321 and is connected to the outer wall of the inner frame 310.

[0054] In this embodiment, the specific configuration of the outer frame 320 is optimized. Specifically, the outer frame 320 is configured as a combined component including at least a base frame 321 and a slanted frame 322. The base frame 321 can be a rectangular frame, which can be welded to the outer wall of the inner frame 310. The base frame 321 protrudes outward along the bottom surface of the inner frame 310 to provide support for the slanted frame 322 and an installation environment located outside the base 100. The slanted frame 322 can be a tripod, which is disposed between the base frame 321 and the outer wall of the inner frame 310, providing an inclined installation environment for the stacked assembly 400. The outer frame 320 provided in this example has an upper and lower structure, which facilitates subsequent assembly.

[0055] In one possible implementation, the inclined frame 322 includes a first sub-frame 3221, a second sub-frame 3222, and a third sub-frame 3223 connected end to end. The first sub-frame 3221 is connected to the base frame 321, the second sub-frame 3222 is connected to the outer wall of the inner frame 310, and the third sub-frame 3223 is inclined, with the working surface located on the side of the third sub-frame 3223 away from the second sub-frame 3222.

[0056] In this embodiment, the specific configuration of the inclined frame 322 is optimized. Specifically, the inclined frame 322 is configured as a combination component including at least a first sub-frame 3221, a second sub-frame 3222, and a third sub-frame 3223. The first sub-frame 3221 can be a short-side rectangular frame, which can be connected to the top of the base frame 321 by welding or other means; the second sub-frame 3222 can be a long-side rectangular frame, which can be connected to the outer wall of the inner frame 310 by welding; the third sub-frame 3223 can be a slanted rectangular frame, whose two ends can be connected to the first sub-frame 3221 and the second sub-frame 3222 by welding, respectively. In this way, the inclined frame 322 can form a right-angled triangular structure, which has stronger stability and support.

[0057] like Figure 8 and Figure 9 As shown, in one possible implementation, the stacking assembly 400 includes a plurality of stacking channels 410, which are mounted on the working surface along the width direction Y and are distributed at intervals along the length direction X of the working surface.

[0058] It should be noted that the length direction X and width direction Y in this application are defined based on the working surface of this application. When the cell stacking equipment has multiple working surfaces in different spatial locations, the length direction X of different working surfaces may be different in space, and the width direction Y of different working surfaces may also be different in space. (Appendix to this application) Figure 1 The length direction X and the width direction Y are based on Figure 1 The rightmost working surface shown in the image is used as the reference for annotation. Figure 2 The length direction X and the width direction Y are based on Figure 2 The leftmost working surface shown in the image is used as the reference for annotation. Figure 7 The length direction X and the width direction Y are based on Figure 7 The rightmost working surface shown in the image is used as a reference for annotation, and all are used as examples to illustrate the length and width directions of the working surface.

[0059] In this embodiment, the specific configuration of the stacking assembly 400 is optimized. Specifically, the stacking assembly 400 is configured as a combined component including at least a plurality of stacking channels 410. The plurality of stacking channels 410 are arranged in columns, rows, or matrices on the working surface to achieve tilted stacking of multiple battery cell groups, thereby improving the stacking neatness and stacking efficiency of the multiple battery cell groups. The stacking assembly 400 extends along the width direction Y to achieve stacking of multiple battery cells in this direction. The stacking assembly 400 provided in this example can simultaneously achieve tilted stacking of multiple battery cell groups with high stacking efficiency; furthermore, since it is rotatably connected to the base 100 through the polyhedral support 300, it has a higher space utilization rate.

[0060] like Figure 8 and Figure 9 As shown, in one possible implementation, the stacking channel 410 includes a loading platform 411, a clamping member 412, and a reference block 413. The loading platform 411 is disposed on the working surface and extends along the width direction Y. The clamping member 412 extends in the same direction as the loading platform 411 and can be close to or away from the loading platform 411 in the length direction X. The reference block 413 is disposed on the side of the loading platform 411 away from the working surface and is located below the clamping member 412.

[0061] In this embodiment, the specific configuration of the stacking channel 410 is optimized. Specifically, the stacking channel 410 is configured as a combination of at least a loading platform 411, clamping members 412, and a reference block 413. The loading platform 411 can be an inverted U-shaped frame, including a top plate and two support plates below it. The top of the plate has two raised rails for accommodating and stacking multiple battery cells. The clamping members 412 can be long plate structures, and two clamping members can be provided, located on both sides of the loading platform 411 along the length direction X. This allows for the simultaneous clamping of the sidewalls of multiple battery cells along the length direction X. The reference block 413 can be a U-shaped abutment block, which can be connected to the lower end of the loading platform 411 by fasteners such as screws / bolts. This allows for the use of the battery cells' own weight to press and secure multiple battery cells in the width direction Y, reducing the need for top clamping members and simplifying the structure. The stacking channel 410 provided in this example has a simple structure and flexible adjustment. It can simultaneously clamp and fix multiple stacked cell groups in at least all directions of the chain. It has high clamping accuracy for cell groups, good neatness of tilted stacking of cell groups, and good tilted stacking effect.

[0062] In one example, the clamping member 412 is provided with urethane adhesive on the side facing the loading platform 411. This urethane adhesive can increase the tightness of the connection between the clamping member 412 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 length direction X, thereby improving the performance of the battery module.

[0063] like Figure 8 and Figure 9 As shown, in one possible embodiment, the stacking channel 410 further includes a second track 414, a second slider 415, and a third drive member 416. The second track 414 extends along the length direction X and is connected to the side of the loading platform 411 facing the working surface. The clamping member 412 is slidably connected to the second track 414 via the second slider 415. The output end of the third drive member 416 is connected to the clamping member 412 and can drive the clamping member 412 to reciprocate along the second track 414.

[0064] In this embodiment, the specific configuration of the stacking channel 410 is further optimized. Specifically, the stacking channel 410 is configured as a combination of at least a loading platform 411, a clamping member 412, a reference block 413, a second track 414, a second slider 415, and a third driving member 416. The second track 414 can be a straight track, which can be connected to the bottom of the loading platform 411 by fasteners such as screws / bolts, and extends out of the loading platform 411 at least in the length direction X, so as to reserve sufficient clamping space in this direction, realize the clamping of cells of various sizes, and improve the applicability of the stacking channel 410. The second slider 415 can be a rectangular block, which can be slidably fitted under the second track 414 via a groove structure and can reciprocate along the second track 414. The clamping member 412 can be connected to the outer wall of the second slider 415 via fasteners such as screws / bolts. Thus, the reciprocating movement of the second slider 415 on the second track 414 allows the clamping member 412 to move closer to or away from the loading platform 411, thereby clamping multiple battery cells stacked on the loading platform 411. The third driving member 416 can be a cylinder, whose cylinder seat can be connected to the loading platform 411 via fasteners such as screws / bolts. Its drive shaft is inserted into the connecting hole on the clamping member 412. Thus, the third driving member 416 can drive the clamping member 412 to reciprocate in the length direction X, improving the accuracy and reliability of movement. The stacking channel 410 provided in this example has a simple structure and compact fit, and can achieve the clamping and fixing of multiple stacked battery cells in the length direction X.

[0065] In one example, two clamping members 412 are provided, located on opposite sides of the long side of the loading platform 411. Two third driving members 416 are provided, with the output end of one third driving member 416 connected to one clamping member 412. This allows for independent driving of a single clamping member 412, improving the clamping adjustment flexibility of the stacking channel 410. Furthermore, the dual-sided clamping also improves the clamping accuracy and stacking neatness of the stacking channel 410. Two second tracks 414 and four second sliders 415 are provided, with two second sliders 415 corresponding to each second track 414. The two ends of one clamping member 412 along the width direction Y are slidably connected to two second tracks 414 via a second slider 415. This improves the movement stability and smoothness of the clamping member 412, ensuring uniform pressure between the inner side of the clamping member 412 and the sidewalls of multiple battery cells, thus enhancing the clamping effect.

[0066] like Figure 8 and Figure 9 As shown, in one possible implementation, the stacking channel 410 further includes a buffer 417, which is disposed on the side of the loading platform 411 facing the working surface and extends out of the loading platform 411 in the length direction X.

[0067] In this embodiment, the specific configuration of the stacking channel 410 is further optimized. Specifically, the stacking channel 410 is configured as a combination of at least a loading platform 411, a clamping member 412, a reference block 413, and a buffer member 417. The buffer member 417 can be an elastic structure with a buffer pin, which includes a connecting cylinder, an elastic element, and a buffer pin. One end of the connecting cylinder is open, facing the outside of the loading platform 411. A limit ring is provided inside the opening. The connecting cylinder extends along the length direction X and can be connected to the bottom of the loading platform 411 through the cooperation of the connecting block and screws / bolts. The elastic element is located in the opening of the connecting cylinder and can be a spring or the like, used to provide elastic buffering force to the buffer pin along the length direction X. The buffer pin has abutting frustums at both ends. One abutting frustum is located in the opening of the connecting cylinder, abutting against the elastic element and limited by the limit ring. The other abutting frustum is located on the outside of the connecting cylinder and abutting against the inner wall of the clamping member 412 to realize the adjustment of the clamping length in the length direction X. Thus, when switching cell lengths, compatibility can be achieved through the buffer 417, increasing the applicability of the stacking channel 410.

[0068] In addition, such as Figure 10 As shown, this application also provides a battery assembly system, including a loading unit 10, a unloading unit 20, and a cell stacking device 30 as described above. The loading unit 10 is located at the loading end of the cell stacking device 30, and the unloading unit 20 is located at the unloading end of the cell stacking device 30.

[0069] In this embodiment, the feeding unit 10 may include a feeding track and a loading tray. The feeding track is located between the cell stacking station and the cell stacking equipment 30. The loading tray is movably mounted on the feeding track and carries multiple cells, thus transporting the cells to the cell stacking equipment 30 for stacking. The unloading unit 20 may include an unloading track and an unloading tray. The unloading track is located between the cell stacking equipment 30 and the next packaging station. The unloading tray is movably mounted on the unloading track and can hold the stacked cell groups, thus transporting the stacked cell groups to the next packaging station for subsequent packaging. This enables intelligent assembly line operation of battery modules, resulting in high production efficiency, good product consistency, and low cost.
