[0036] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0037] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model.

[0039] Please refer to Figures 1 to 12 , a battery module boxing equipment, including a tray, a lifting mechanism 2 and a transfer assembly 1. Specifically, the tray is used to carry the battery module; the lifting mechanism 2 is used to carry and lift the tray; the transfer assembly 1 can transfer the box body to the lifting mechanism 2, the opening of the box body faces the tray, and the lifting mechanism 2 acts on the tray so that the battery module and the box body move towards each other to enter the box body. In this embodiment, during the process of the battery module entering the box, the battery module is placed on the tray, and the transfer assembly 1 is used to carry the box body for a large-range movement to approach the battery module on the tray, and it is buckled on the battery module to complete the boxing. This avoids the risk of the battery module falling in the traditional boxing method and also avoids large deformation of the battery module caused by clamping it. Moreover, the handling of the box body is relatively simple, and compared with the traditional handling of the battery module, it can greatly improve the speed of the battery module and the box body approaching each other, which is beneficial to improving the boxing speed of the battery module.

[0040] It should be noted that when the battery module is put into the box to form a battery pack, the transfer assembly 1 can transfer the tray and the battery pack together, and then the battery pack can be flipped and the tray can be removed at other workstations for the next assembly work.

[0041] In this embodiment, the tray includes a sub-tray 31 and a mother-tray 32. The sub-tray 31 and the mother-tray 32 are stacked. The battery module is supported on the sub-tray 31, and a pre-pressing assembly is arranged on the mother-tray 32. The pre-pressing assembly is used to press the battery module; the lifting mechanism 2 includes an overall lifting part 22 and a local lifting part 23. The overall lifting part 22 is used to support the mother-tray 32, and the local lifting part 23 is used to lift the sub-tray 31 so that the sub-tray 31 can be longitudinally separated from the mother-tray 32. By setting the tray as a structure where the mother and son can be disassembled, it is convenient to shape the battery module through the pre-pressing assembly before the battery module enters the box, and it is also beneficial to remove the sub-tray 31 together with the battery pack after the battery module enters the box. During use, there is no need to apply pressure to shape the battery module after it enters the box. During the subsequent transfer of the battery pack, only the sub-tray 31 and the battery pack need to be transferred, reducing the transfer load and ensuring the safety of the production process.

[0042] Furthermore, the lifting mechanism 2 further includes a main frame 21. A receiving space is formed on the main frame 21, and both the overall lifting part 22 and the local lifting part 23 are installed in the receiving space; a pressing part 25 is arranged on the main frame 21, and the pressing part 25 acts on the pre-pressing assembly to press the battery module; a bearing part 24 is arranged on the main frame 21, and the bearing part 24 is used to support the mother-tray 32.

[0043] As Figure 2 shown, the carrier 24 includes a support beam 241 which extends along the second direction Y. A plurality of rollers 242 are arranged on the support beam 241 and are spaced along the second direction Y. During use, when the tray is conveyed to the lifting mechanism 2 through the assembly line, the mother tray 32 is supported on the rollers 242, specifically above the overall lifting part 22 and the partial lifting part 23 in the longitudinal direction. At this time, the overall lifting part 22 ascends longitudinally upward until it abuts against the mother tray 32, and the mother tray 32, that is, the entire tray, is lifted longitudinally upward until the pre-pressing assembly and the pressing member 25 are at the same longitudinal height. Next, the pressing member 25 acts on the pre-pressing assembly, and the battery module on the sub-tray 31 is pre-pressed and shaped through the pre-pressing assembly to facilitate subsequent smooth entry into the box. Finally, the partial lifting part 23 ascends the sub-tray 31 longitudinally upward, and the battery module moves longitudinally upward and gradually enters the box while gradually separating from the pre-pressing assembly.

[0044] In this embodiment, the pre-pressing assembly presses on the end plate of the battery module.

[0045] Furthermore, there are two pressing members 25 which are arranged oppositely in the first direction X, and the tray is located between the two pressing members 25. A first limiting member 26 and a second limiting member 27 are further arranged on the main frame 21. The first limiting member 26 and the second limiting member 27 are arranged oppositely in the second direction Y, and the tray is located between the first limiting member 26 and the second limiting member 27. The first direction X is perpendicular to the second direction Y. In this embodiment, the length direction of the battery module is parallel to the first direction X. The battery module includes a plurality of battery cells which are stacked along the first direction X, and the end plate is at the end of the battery module in the length direction. The two pressing members 25 are used for shaping the battery module in the first direction X, and can also limit the tray and the battery module thereon in the first direction X, while the first limiting member 26 and the second limiting member 27 cooperate with each other to limit the tray in the second direction Y, thereby realizing the limiting and assembly of the tray on the lifting mechanism 2.

[0046] In this embodiment, the first limiting member 26 includes a limiting plate 261 which is arranged on the main frame 21, and a limiting wheel 262 is arranged on the limiting plate 261. During use, the limiting wheel 262 abuts against the mother tray 32.

[0047] The second limiting member 27 includes a mounting plate 271 which is arranged on the main frame 21. A third driving member 272 and a limiting block 273 are arranged on the mounting plate 271, and the third driving member 272 is used to drive the limiting block 273 to move longitudinally.

[0048] The overall lifting part 22 includes a lifting frame 222 and a first lifting component 223. The first lifting component 223 is installed on the main frame 21 and is used to lift the lifting frame 222 to abut against the mother tray 32. The local lifting part 23 can pass through the lifting frame 222 and abut against the son tray 31. Such a setting is beneficial to improving the structural strength of the overall lifting part 22 without interfering with the local lifting part 23.

[0049] Specifically, the first lifting component 223 includes a lifting block 2231. A lifting inclined surface is configured on the lifting block 2231, and a bearing surface adapted to the lifting inclined surface is configured on the lifting frame 222. The lifting block 2231 is movably assembled on the main frame 21. During use, the lifting block 2231 is driven to move, and the lifting inclined surface drives the lifting frame 222 to move upward longitudinally through the bearing surface.

[0050] In this embodiment, the lifting block 2231 is slidably connected to the main frame 21 through a slide rail and slider assembly. Optionally, the lifting block 2231 can slide in the second direction Y.

[0051] An extension column 2221 is configured on the lifting frame 222. The extension column 2221 extends longitudinally, and a bearing surface is configured at the end of the extension column 2221 far from the lifting frame 222. Preferably, a roller 2222 is configured at the end of the extension column 2221 far from the lifting frame 222, and the bearing surface is the wheel surface of the roller 2222. In this way, the transmission friction between the lifting frame 222 and the lifting block 2231 can be reduced.

[0052] During use, the bearing surface of the lifting frame 222 abuts against the lifting inclined surface under the action of gravity. Due to the action of the tray, the lifting frame 222 has no room for movement in the horizontal direction. Therefore, when the lifting block 2231 moves, the lifting inclined surface can cooperate with the roller 2222, that is, the bearing surface, to realize the lifting or lowering of the lifting frame 222 longitudinally.

[0053] In other embodiments, the bearing surface can also be an inclined surface adapted to the lifting inclined surface.

[0054] It should be noted that the above-mentioned horizontal direction refers to any direction within a plane perpendicular to the longitudinal direction.

[0055] In this embodiment, a first bearing plane and a second bearing plane are also configured on the lifting block 2231. The first bearing plane, the second bearing plane and the lifting inclined surface are on the same side of the lifting block 2231. In this embodiment, the first bearing plane, the lifting inclined surface and the second bearing plane are connected in sequence. As Figure 3As shown, the first bearing plane is at the low end of the jacking inclined plane, and the second bearing plane is at the high end of the jacking inclined plane. During use, the roller 2222 is first on the first bearing plane. At this time, the overall jacking part 22, that is, the jacking frame 222, does not jack the mother tray 32 longitudinally. When the jacking block 2231 moves along the second direction Y until the bearing surface is within the range of the jacking inclined plane, the jacking frame 222 jacks the mother tray 32 upward longitudinally. When the bearing surface reaches the second bearing plane, the overall jacking part 22 completes the jacking of the mother tray 32, that is, the tray. And at this time, the pressing part 25 and the pre-pressing assembly are at the same longitudinal height. Subsequently, the battery module is compacted and shaped by the cooperation of the pressing part 25 and the pre-pressing assembly. Then, the box body is transported and inverted above the battery module through the transfer assembly 1. At this time, the mother tray 32 is jacked by the local jacking part 23 so that the battery module can enter the box body.

[0056] Furthermore, as Figure 3 shown, the overall jacking part 22 further includes a transition frame 221. The transition frame 221 includes a cross frame 2211 and a longitudinal frame 2212 that are connected to each other. The first jacking assembly 223 is arranged on the cross frame 2211. The local jacking part 23 includes a top plate 231. The top plate 231 is slidably connected to the longitudinal frame 2212. A first driving part is arranged on the main frame 21. The first driving part is used to drive the top plate 231 to slide longitudinally relative to the longitudinal frame 2212 to abut against or disengage from the sub-tray 31. As Figure 3 shown, specifically, mounting columns 232 are arranged on the lower side surface of the top plate 231 along the longitudinal direction. The mounting columns 232 are slidably mounted on the longitudinal frame 2212 through a slide rail and slider assembly. During use, the first driving part drives the top plate 231 or the mounting columns 232 so that the top plate 231 moves longitudinally.

[0057] In this embodiment, auxiliary support blocks 2311 are configured on the top plate 231. The auxiliary support blocks 2311 can move longitudinally to abut against or disengage from the mother tray 32. Optionally, a first through hole and a first telescopic member are arranged on the top plate 231. The auxiliary support blocks 2311 are mounted on the telescopic end of the first telescopic member. The first telescopic member drives the auxiliary support blocks 2311 to move longitudinally through the first through hole. Preferably, the first telescopic member is a cylinder. During use, after the jacking frame 222 jacks the mother tray 32, there is a risk of force deformation at the middle position of the mother tray 32 without support. Therefore, driving the auxiliary support blocks 2311 to abut against the mother tray 32 by the first telescopic member can well avoid this risk. It should be noted that when the first driving part drives the top plate 231 to abut against and jack the sub-tray 31, the first telescopic member drives the auxiliary support blocks 2311 to gradually move downward longitudinally to ensure that the top plate 231 moves upward longitudinally under the action of the first driving part.

[0058] Optionally, the first driving part includes but is not limited to a cylinder, a hydraulic cylinder or an electric push rod.

[0059] In this embodiment, as Figure 3 shown, ten first struts 233 are arranged on the top plate 231, and first support plates corresponding to the first struts 233 are arranged on one side of the sub-tray 31 facing the first struts 233. During use, the first struts 233 pass through the mother tray 32 and abut against the first support plates.

[0060] Ten main support blocks are arranged on the lifting frame 222, and second support plates corresponding to the main support blocks are arranged on one side of the mother tray 32 facing the main support blocks.

[0061] As Figures 10 to 12 shown, the sub-tray 31 includes a first main board 311, a linkage pin hole 3111 is penetrated through the first main board 311, the mother tray 32 includes a second main board 321, and a linkage pin shaft 3211 adapted to the linkage pin hole 3111 is arranged on the second main board 321.

[0062] Furthermore, the overall lifting part 22 includes a first positioning pin 224, and a first pin hole adapted to the first positioning pin 224 is arranged on the mother tray 32.

[0063] As Figure 12 shown, the preloading assembly includes a support 322 arranged on the second main board 321, the support 322 can penetrate through the first main board 311, a guide shaft is slidably assembled on the support 322, the guide shaft penetrates through the support 322, a first pressing plate 323 is arranged at one end of the guide shaft close to the battery module, a second pressing plate 324 is arranged at the other end of the guide shaft, a first spring 325 is pressed between the second pressing plate 324 and the support 322, and the first spring 325 is sleeved outside the guide shaft.

[0064] As Figure 2 shown, the pressing member 25 includes a pressing plate 251, the pressing plate 251 is slidably installed on the main frame 21 through a slide rail and slider assembly, and a second driving member 252 is arranged on the main frame 21, and the second driving member 252 is used to drive the pressing plate 251 to approach or move away from the second pressing plate 324. The second driving member 252 includes, but is not limited to, a cylinder, a hydraulic cylinder or an electric push rod.

[0065] During use, the second driving member 252 drives the pressing plate 251 to apply pressure to the second pressing plate 324. At this time, the guide shaft moves along the first direction X relative to the support 322 so that the first pressing plate 323 abuts against and presses tightly against the end plate of the battery module to realize the pressing and shaping of the battery module. When the battery module is put into the box, the end plate of the battery module slides relative to the first pressing plate 323. After the box loading is completed, the acting force of the pressing plate 251 on the second pressing plate 324 is removed, and the first spring 325 acts on the second pressing plate 324 to reset the first pressing plate 323.

[0066] As Figure 1 、 Figures 4 to 9As shown in the figure, the transfer assembly 1 includes: two gantry guide beams 11; a transverse guide beam 12, which spans between the two gantry guide beams 11. A hoisting member 13 is provided on the transverse guide beam 12, and a grasping portion 14 for grasping the box body is configured on the hoisting member 13. The hoisting member 13 is used to drive the grasping portion 14 to move longitudinally, and the grasping portion 14 can rotate relative to the hoisting member 13 within a plane parallel to the tray. In this embodiment, the transverse guide beam 12 can move along the extension direction of the gantry guide beam 11, that is, the second direction Y, and the hoisting member 13 can move along the extension direction of the transverse guide beam 12, that is, the first direction X. Therefore, after the grasping portion 14 grasps the box body, it can move in three-dimensional space to transport the box body to the designated position. At the same time, the rotation of the grasping portion 14 within a plane parallel to the tray can accurately adjust the angle of the box body, facilitating the reverse buckling assembly of the box body and the module.

[0067] Furthermore, as Figures 6 to 8 shown, the grasping portion 14 includes a main body frame 141. A fixed plate 142 is provided on one side of the main body frame 141 facing the tray. A double-headed screw rod 144 is rotatably installed on the fixed plate 142. Both end plates of the double-headed screw rod 144 are threadedly connected with a grasping portion 143. The grasping portion 143 is slidably connected to the main body frame 141, and the double-headed screw rod 144 drives the two grasping portions 143 to approach or move away from each other. In this embodiment, the double-headed screw rod 144 is driven by a motor to synchronously drive the two grasping portions 143 to move. In other embodiments, the two grasping portions 143 can also act asynchronously, that is, they can be respectively driven by screw rods. When in use, first adjust the grasping portion 14 so that it is above the box body, and then drive the grasping portion 14 to approach the box body longitudinally through the hoisting member 13, so that the two grasping portions 143 are in the grasping position, and then drive the two grasping portions 143 to approach synchronously through the double-headed screw rod 144 to hook the box body.

[0068] Furthermore, the grasping portion 143 includes a moving plate 1431. The moving plate 1431 is threadedly connected to the double-headed screw rod 144, and the moving plate 1431 is slidably connected to the main body frame 141 through a slide rail-slider assembly; a claw for hooking the box body is provided on the moving plate 1431. Further, the claw includes a fixed frame body 1432. A claw body 1433 is movably installed on the fixed frame body 1432, and the claw body 1433 can move longitudinally relative to the fixed frame body 1432.

[0069] Specifically, the claw body 1433 is L-shaped. A fixing pin 14331 is provided at the bottom of the claw body 1433. The fixing pin 14331 extends vertically upward. A fixing hole corresponding to the fixing pin 14331 is configured on the box body. Here, the fifth driving member 1434 is used to lift the claw body 1433 vertically upward so that the fixing pin 14331 is inserted into the fixing hole to complete the fixing of the box body, improving the stability of the box body during the lifting and handling process.

[0070] An extension bracket 145 is provided on the moving plate 1431. A transfer pin 146 is provided on the extension bracket 145. The transfer pin 146 extends in the direction away from the box body of the claw body 1433; a transfer hole 3113 adapted to the transfer pin 146 is configured on the sub-tray 31. During use, when the battery box body is transferred to the battery module and put into the box, during the process of the claw body 1433 disengaging from the box body, the transfer pin 146 is inserted into the transfer hole 3113, facilitating the subsequent handling of the sub-tray 31 and the battery pack.

[0071] An anti-fooling long pin 16 is configured on the main body frame 141. An anti-fooling hole 3112 adapted to the anti-fooling long pin 16 is configured on the sub-tray 31. The anti-fooling long pin 16 is slidably connected to the main body frame 141. A second spring 18 is sleeved on the anti-fooling long pin 16. The second spring 18 is pressed between the anti-fooling long pin 16 and the main body frame 141. An induction component 19 is configured on the main body frame 141 for sensing the anti-fooling long pin 16. Specifically, as Figure 6 and Figure 8 shown, an anti-fooling bracket 17 is configured on the main frame body. The upper end of the anti-fooling long pin 16 is slidably installed on the anti-fooling bracket 17 through a linear bearing. A guiding bracket 171 is configured on the anti-fooling bracket 17. The upper end of the anti-fooling long pin 16 penetrates through the guiding bracket 171. The induction component 19 is installed on the anti-fooling bracket 17 or the guiding bracket 171 for sensing the position change of the upper end of the anti-fooling long pin 16. A shoulder is provided at the upper end of the anti-fooling long pin 16. The second spring 18 is sleeved between the shoulder and the guiding bracket 171. During use, when the assembly is successful, the anti-fooling long pin 16 is accurately assembled into the anti-fooling hole 3112, and the equipment operates normally to the next step; when the gripping part 14 or the posture of the box body is not standard, the anti-fooling long pin 16 is misaligned with the anti-fooling hole 3112. During the process of moving downward longitudinally, the anti-fooling long pin 16 is blocked and moves upward. At this time, the induction component 19 receives this signal, and the equipment does not continue to move downward but performs posture adjustment to prevent the equipment from crashing. The second spring 18 here is used to reset the anti-fooling long pin 16.

[0072] As Figure 7 and Figure 9As shown, a buffer plate 147 is provided on the fixed plate 142. The buffer plate 147 can move longitudinally relative to the fixed plate 142. The buffer plate 147 is closer to the box body than the fixed plate 142. It further includes a damping member 1481. The damping member 1481 acts on the buffer plate 147 to have a damping force when the buffer plate 147 moves away from the box body. Specifically, an extension plate 149 is provided on the fixed plate 142, and a guide rod is provided on the buffer plate 147. The guide rod is slidably mounted on the extension plate 149 through a linear bearing. A buffer bracket 148 is provided on the extension plate 149 or the fixed plate 142. A third spring is pressed between the buffer bracket 148 and the buffer plate 147. The third spring here is the aforementioned damping member 1481. During the process of the battery entering the box, the box body first abuts against the buffer plate 147 after being stressed. The buffer plate 147 can provide a buffer distance for the box body before it abuts against the fixed plate 142, avoiding damage caused by hard contact of the box body.

[0073] In this embodiment, as Figure 5 shown, the hoisting member 13 is movably mounted on the transverse guide beam 12 through a slide plate. Specifically, the hoisting member 13 includes a hoisting column 131 and a fourth driving member 133 provided on the slide plate.
