Description

TECHNICAL FIELD

[0001] The present application relates to a tray, in particular to a tray for pressing battery cells. BACKGROUND

[0002] With the implementation of energy-saving and environmental protection concepts, traditional machines and equipment that provide internal energy by internal combustion engines are gradually replaced by batteries and the like. Existing batteries are usually composed of multiple groups of battery cells, i.e. battery modules.

[0003] With the increasing consumption of non-renewable resources, especially the consumption of oil resources, people have to start considering the sustainable development of the automobile industry. New energy vehicles will become the mainstream of automobile development in the first few decades of the new century and the consensus of all industry insiders in the automobile industry. Developing new energy vehicles is an important breakthrough for the automobile industry to address energy security, climate change and structural upgrading. Power battery packs are the power source for new energy vehicles, and they play a decisive role in the performance of new energy vehicles.

[0004] However, traditional battery production lines mostly use manual + special machine mode, and various uncertain factors cause performance differences in each single power battery at the beginning, greatly reducing the power supply performance, stability and safety of the battery pack, and increasing labor intensity.

[0005] The development direction of automobile power battery packs is to improve the energy density of the battery pack, reduce the manufacturing cost, and improve the safety of the battery pack; among them, the technical route of energy density mainly has two directions of improving the energy density of single battery cell and improving the energy density of the whole pack. The chemical system of single battery cell is continuously improved from NCM 532, NCM 811 to Ni 55; the design of the whole pack PACK also switches from steel, aluminum alloy to composite material.

[0006] In the second half of 2019, CATL, BYD and Honeycomb Energy all launched the battery pack CTP (Cell to Pack) technology, which simplifies the manufacturing process of battery cells -> modules -> whole pack into battery cells -> whole pack, removing the intermediate state of modules. This technology can greatly reduce the weight of the whole pack, thereby improving the energy density,

[0007] LCTP is a battery module structure optimized on the basis of CTP, the most obvious place is to increase the length of the traditional 148mm-220mm battery cell to 300mm-600mm, and the number of battery cells in a module from 8-12 to 50-70; that is, increase the volume and capacity of single battery cell and single module, reduce the number of battery cell modules and components in the whole battery pack, further improve the energy density of the product, and reduce the manufacturing cost of the product.

[0008] However, the conventional processing equipment only places the battery cells on the tray by the mechanical arm when processing the battery pack, and whether the battery cells placed on the tray are aligned only depends on the positioning of the mechanical arm. After the mechanical arm runs for a long time, there is process deviation to some extent, and the mechanical arm with deviation will cause the battery cells to be arranged disorderly after placing the battery cells on the tray, thereby affecting the energy density of the whole battery pack.

[0009] In addition, since the battery cells on the tray also need to be prevented from being placed disorderly, the battery cells cannot be fixed, and the battery cells that cannot be fixed may move away from the original position during the conveying process. Once the battery cell group is conveyed to the next process and is fixed, it will inevitably cause the battery cells to be arranged disorderly, thereby affecting the energy density of the whole battery pack.

[0030] The following description is presented to enable any person skilled in the art to practice the present application as claimed. The preferred embodiments disclosed herein are only examples of the present application and alternative embodiments will be apparent to those skilled in the art. The patentable scope of the present application is defined by the appended claims and can include other embodiments that offer optional preferred alternatives.

[0031] Reference Figures 1 to 10 A preferred embodiment of the alignable battery cell battery pack processing apparatus according to the present application will be described in detail below, wherein the alignable battery cell battery pack processing apparatus comprises an apparatus body 10 and an alignment assembly 30. The apparatus body 10 forms a tray entry end 101 and a tray exit end 102, and the apparatus body 10 forms an entry 1001, an exit 1002 at the tray entry end 101 and the tray exit end 102 respectively, and a processing area 1003 between the entry 1001 and the exit 1002.

[0032] It is worth mentioning that the tray body 71 of a tray 700 entered from the entry 1001 can enter the processing area 1003 from the entry 1001, and can be removed from the exit 1002 after being processed in the processing area 1003.

[0033] After the tray body 71 is placed in the processing area 1003, it can be used to hold battery cells 800. As shown, a plurality of battery cells 800 are arranged in an interval and parallel manner between the tray entry end 101 and the tray exit end 102.

[0034] As can be understood by those skilled in the art, due to the cumulative tolerance when the battery cells 800 are placed in the tray body 71 by a mechanical arm or manually, the plurality of battery cells 800 are not completely parallel, and the two ends of the battery cells 800 are not completely aligned.

[0035] In one preferred embodiment of the present application, the alignment assembly 30 is arranged to be maintained at a predetermined height above the processing area 1003, so that the alignment assembly 30 is maintained above the tray when the tray body 71 is placed above the processing area 1003, so that the tray body 71 is not interfered by the alignment assembly 30 when the tray body 71 is filled with the battery cell 800 and removed from the outlet 1002. In other words, since the alignment assembly 30 is arranged to be maintained at a predetermined height above the processing area 1003, the alignment assembly 30 does not block the movement of the tray body 71.

[0036] As an example, the alignment assembly 30 is arranged at the tray inlet end 101, so that the alignment assembly 30 does not interfere with the movement of the tray body 71 when the robot arm 10 places the battery cell 800 on the tray body 71.

[0037] In particular, the alignment assembly 30 comprises a pair of centering members 31, wherein each of the centering members 31 comprises a pair of centering arms 311 and a centering drive unit 312, wherein each of the centering arms 311 is arranged in a vertical direction and is synchronously movable in a direction perpendicular to the vertical direction and perpendicular to the movable direction of the tray body 71 at a predetermined height above the processing area 1003.

[0038] The alignment assembly 30 further comprises a moving assembly 32, wherein the centering members 31 are movably connected to the moving assembly 32 in the movable direction of the tray body 71.

[0039] In one embodiment, the moving assembly 32 comprises a moving rail 321 arranged in the movable direction of the tray body 71 and maintained at a predetermined height above the processing area 1003, and a drive motor 322, wherein the centering members 31 are movably connected to the drive motor 322 along the moving rail 321.

[0040] As understood by those skilled in the art, when the battery cell 800 is placed on the tray body 71, the drive motor 322 can be driven to move above the position corresponding to the battery cell 800, and then the centering drive unit 312 is controlled to drive the pair of centering arms 311 to move towards each other, so that the pair of centering arms 311 clamps the battery cell 800 from both sides of the battery cell 800 placed on the tray body 71. Then, the centering drive unit 312 is controlled to drive the pair of centering arms 311 to move away from each other, so that the pair of centering arms 311 moves away from both sides of the battery cell 800 placed on the tray body 71.

[0041] It is worth mentioning that, since the pair of the centering arms 311 are synchronously moved, after the each of the battery cells 800 placed on the tray body 71 is clamped by the pair of the centering arms 311, the two ends of all the battery cells 800 placed on the tray body 71 will be aligned along the direction in which the tray body 71 is movable. In this way, it can be ensured that the two ends of the battery cells 800 are carried on the tray body 71 in an orderly manner. That is to say, in this way, the battery pack processing equipment capable of aligning battery cells can automatically align the battery cells 800 placed on the tray body 71 in the length direction, so as to ensure that the battery cells 800 placed on the tray body 71 are aligned.

[0042] In another embodiment, the aligning assembly 30 comprises a pressing member 33 and the moving assembly 32, wherein the pressing member 33 is movably connected to the moving assembly 32 along the direction in which the tray body 71 is movable.

[0043] In the embodiment, the moving assembly 32 comprises a moving guide rail 321 arranged along the direction in which the tray body 71 is movable and kept at a predetermined height higher than the processing area 1003, and a driving motor 322, wherein the pressing member 33 is movably connected to the driving motor 322 along the moving guide rail 321.

[0044] The pressing member 33 comprises a pressing arm 331 and a pressing arm driving unit 332, wherein the pressing arm 331 is vertically movably connected to the pressing arm driving unit 332, so that the pressing arm 331 can press the battery cells placed on the tray body 71 from the vertical direction. In this way, the battery pack processing equipment capable of aligning battery cells can automatically align the battery cells 800 placed on the tray body 71 in the height direction, so as to ensure that the battery cells placed on the tray are aligned.

[0045] In a preferred embodiment, the pressing arm 331 is arranged at the middle of the pair of the centering arms 311, and both the centering member 31 and the pressing arm 331 are vertically movably connected to the pressing arm driving unit 332. In addition, both the centering member 31 and the pressing member 33 are movably connected to the moving assembly 32 along the direction in which the tray body 71 is movable.

[0046] It can be understood by those skilled in the art that, in the embodiment, the battery pack processing equipment capable of aligning battery cells can automatically align the battery cells 800 placed on the tray body 71 in the length direction, and can also automatically align the battery cells 800 placed on the tray body 71 in the height direction. In this way, it can be ensured that the battery cells 800 are placed on the tray body 71 in an orderly manner.

[0047] Further, the tray 700 further comprises at least one pressing assembly 72, wherein the pressing assembly 72 is arranged on both sides of the tray body 71, so as to press the battery cell 800 after the alignment assembly 30 aligns the battery cell 800 on the tray body 71.

[0048] More specifically, the pressing assembly 72 comprises at least one pressing beam 721, a moving member 722 and an automatic pressing member 723.

[0049] The pressing beam 721 is arranged to extend along the movable direction of the tray body 71, and the height of the top of the pressing beam 721 is lower than the height of the top of the battery cell 800 placed on the tray body 71, so as to facilitate the placement of the battery cell 800 on the tray body 71.

[0050] The moving member 722 comprises a vertical guide rail 7221 and a horizontal guide rail 7222, wherein the vertical guide rail 7221 is arranged along the vertical direction of the tray body 71, the horizontal guide rail 7222 is arranged along the horizontal direction perpendicular to the movable direction of the tray body 71, and the bottom of the vertical guide rail 7221 is slidably installed on the horizontal guide rail 7222 along the extension direction of the horizontal guide rail 7222. The pressing beam 721 is slidably installed on the vertical guide rail 7221.

[0051] That is, the pressing beam 721 can slide along the vertical guide rail 7221 along the vertical direction, and can slide along the horizontal guide rail 7222 along the extension direction of the horizontal guide rail 7221 along with the vertical guide rail 7221.

[0052] The automatic pressing member 723 comprises a top connecting member 7231, a bottom connecting member 7232 and at least one elastic compression member 7233, wherein the top connecting member 7231 is connected to the pressing beam 721, the elastic compression member 7233 is arranged between the top connecting member 7231 and the bottom connecting member 7232, and the bottom connecting member 7232, the elastic compression member 7233 and the top connecting member 7231 are arranged from bottom to top on the tray body 71.

[0053] The battery pack processing equipment for alignable battery cells further comprises a pressing driving assembly 50, wherein the pressing driving assembly 50 is arranged to assist the pressing assembly 72 to press the battery cell 800 after the alignment assembly 30 aligns the battery cell 800 on the tray body 71.

[0054] Specifically, the pressure maintaining driving assembly 50 comprises a lifting member 51 and a pushing member 52. The lifting member 51 and the pushing member 52 are both arranged on the device body 10.

[0055] The lifting member 51 forms a lifting end 5101, wherein the lifting end 5101 is movable in the vertical direction when the lifting member 51 is working. In one embodiment, the lifting member 51 comprises a lifting arm 511 and at least one lifting cylinder 512, wherein the lifting arm 511 forms the lifting end 5101, and the lifting arm 511 is liftable mounted on the device body 10 through the lifting cylinder 512.

[0056] It is worth mentioning that the tray body 71 correspondingly forms at least one vertical through hole 7101, wherein the vertical through hole 7101 is located on the path of the lifting end 5101 movement, and the vertical through hole 7101 corresponds to the bottom connecting piece 7232 in the vertical direction, so as to push the bottom connecting piece 7232 upward through the vertical through hole 7101 when the lifting end 5101 rises.

[0057] The pushing member 52 forms a pushing end 5201, wherein the pushing end 5201 is movable in the vertical direction when the pushing member 52 is working. In one embodiment, the lifting member 51 comprises a pushing arm 521 and at least one pushing cylinder 522, wherein the pushing arm 521 forms the pushing end 5201, and the pushing arm 521 is movably mounted on the device body 10 in the horizontal direction perpendicular to the arrangement direction of the battery cell 800 through the lifting cylinder 512.

[0058] It is worth mentioning that after the lifting member 51 lifts the automatic pressing member 723, the pressing beam 721 can rise to the horizontal height corresponding to the pushing end 5201 with the top connecting piece 7231 of the automatic pressing member 723. Subsequently, the pushing member 52 can push the pressing beam 721 to the upper side of the battery cell 800 carried on the tray body 71.

[0059] Subsequently, as the jacking member 51 moves downward, the bottom connecting member 7232 will be moved toward the tray body 71 by the restoring force of the elastic compression member 7233, and the elastic compression member 7233 will remain in the compressed state. At this time, since the pressing beam 721 has moved to the top end of the vertical guide rail 7221 and cannot move upward any more, the elastic compression member 7233 will always give the bottom connecting member 7232 a pressure tending to move toward the tray body 71. In this way, the pressing beam 721 will give the battery cell 800 a downward pressure from above the battery cell 800 carried on the tray body 71.

[0060] As can be understood by those skilled in the art, since the pressing beam 721 can give the battery cell 800 a downward pressure from above the battery cell 800 carried on the tray body 71, the battery cell 800 carried on the tray can be pressed. In this way, the battery cell 800 will not be displaced in the subsequent processing, so as to ensure the density of the battery cell 800.

[0061] Further, the equipment body 10 is provided with at least one positioning structure, such as a positioning pin or a positioning groove. The tray 700 is also provided with a fixing structure, such as a fixing groove or a fixing pin, at a position corresponding to the positioning structure.

[0062] Therefore, after the tray 700 is carried on the equipment body 10, the tray 700 can be stably carried on the equipment body 10 through the positioning structure and the fixing structure. In this way, when the battery cell 800 is placed on the tray 700 or aligned and placed on the tray 700 by the alignment assembly 30, the mutual positions of the battery cells 800 will not be affected by the movement of the tray 700.

[0063] It is worth mentioning that the pressure maintaining driving assembly 50 can be arranged at the inlet 1001 and / or the outlet 1002.

[0064] As can be understood by those skilled in the art, the centering driving unit 312 and / or the pressing arm driving unit 332 can be arranged as a servo motor. In addition, the elastic compression member 7233 can be arranged as a spring.

[0065] As Figure 6 and Figure 7The automatic pressing member 723 comprises at least one telescopic guiding column 7234, wherein the top of the telescopic guiding column 7234 is connected to the top connecting member 7231, and the telescopic guiding column 7234 is arranged through the bottom connecting member 7232, so that the bottom connecting member 7232 can move along the telescopic guiding column 7234 when it moves in the vertical direction, thereby avoiding the bottom connecting member 7232 from being deflected when the elastic compression member 7233 is compressed.

[0066] Further, the alignment assembly 30 further comprises a spacing alignment member 34, wherein the spacing alignment member 34 comprises a pair of positioning arms 341 and at least one driving member 342 extending along the direction from the inlet 1001 to the outlet 1002, wherein the positioning arms 341 are arranged on both sides of the tray 700 by the driving member 341 and can be arranged towards or away from each other.

[0067] A plurality of positioning grooves 3401 are arranged on each of the positioning arms 341 along the direction from the inlet 1001 to the outlet 1002, and the positioning grooves 3401 on one of the positioning arms 341 are symmetrically arranged with the positioning grooves 3401 on the other of the positioning arms 341. In this way, each of the positioning grooves on the two positioning arms 341 forms a clamping groove for positioning the battery cell 800.

[0068] Especially before the operation of the centering member 31 and the pressing member 33, the driving member 342 can be controlled to move the pair of positioning arms 341 towards each other, so that the pair of positioning grooves 3401 on the pair of positioning arms 341 are separated by a predetermined distance.

[0069] It is worth mentioning that the width of the positioning grooves is slightly larger than the thickness of the battery cell 800, and the top of the positioning arm 341 is lower than the height of the battery cell 800, so that the positioning arm 341 can not only position the spacing between the battery cells 800 carried on the tray 700, but also will not interfere with the centering member 31 and the pressing member 33.

[0070] As Figure 10 As a preferred, the tray 700 further comprises a pressure adjusting assembly 73, wherein the pressure adjusting assembly 73 is arranged to adjust the compression amount of the elastic compression member 7233 of the automatic pressing member 723, thereby adjusting the pressure given by the automatic pressing member 723 to the battery cell 800 when tending to reset.

[0071] Specifically, in one embodiment, the pressure adjusting assembly 73 is implemented as a bolt, wherein the bolt is vertically screwed to the tray body 71, and the screw rod top of the bolt abuts against the bottom wall of the bottom connecting piece 7232, so that the distance between the bottom connecting piece 7232 and the tray body 71 can be adjusted by rotating the bolt, and thus the pressure given by the automatic pressing member 723 to the battery cell 800 when tending to reset can be adjusted.

[0072] According to another aspect of the present application, the present application provides a working method of a battery pack processing device for aligning battery cells, wherein the processing method of the battery pack processing device for aligning battery cells comprises the following steps:

[0073] S101, the bottom connecting piece 7232 is pushed by the lifting end 5101 of the jacking member 51 to lift the pressing beam 721 to a predetermined height above the top of the battery cell 800 on the tray 700 and horizontally aligned with the horizontal pushing member 52;

[0074] S101, the pressing beam 721 is horizontally pushed by the horizontal pushing end 5201 of the horizontal pushing member 52 above the top of the battery cell 800;

[0075] S103, the bottom connecting piece 7232 is pressed downward to the tray body 71 by the elastic recovery force of the elastic compression member 7233, so as to pull the pressing beam 721 connected to the top connecting piece 7231 to press the battery cell 800 on the tray body 71 downward.

[0076] In one embodiment, the working method of the battery pack processing device for aligning battery cells comprises:

[0077] S201, a pair of the centering arms 311 is driven by the centering driving unit 312 of the centering member 31 to clamp the battery cell 800 on the tray body 71;

[0078] S202, the centering member 31 is driven by the driving motor 322 of the moving assembly 32 to move along the moving guide rail 321 parallel to the arrangement direction of the battery cell 800 on the tray body 71, so that a pair of the centering arms 311 is respectively kept at both ends of the other battery cell 800 on the tray body 71, and then the step S201 and the step S202 are repeated to align both ends of the other battery cell 800 on the tray body 71.

[0079] As preferred, when the pair of the centering arms 311 clamps the battery cell 800 on the tray body 71, the battery cell 800 on the tray body 71 is aligned in height by pressing the battery cell 800 downward with a pressing arm 331 arranged between the pair of the centering arms 311.

[0080] Those skilled in the art will understand that the above description and the embodiments of the application shown in the drawings are only examples and do not limit the application. The advantages of the application have been fully and effectively achieved. The functions and structural principles of the application have been shown and described in the embodiments, and the embodiments of the application can be modified or changed in any way without departing from the principles.
