Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a conveyor line and an automatic assembly equipment. Background Technology

[0002] Currently, the assembly of power battery packs for new energy commercial vehicles mainly relies on manual placement of battery packs into battery frames, resulting in low efficiency, high risk, and wasted human resources. Some related technologies utilize conveyor lines to transport battery packs to the corresponding housing layers within the battery frame. However, the structural dimensions of these conveyor lines are limited by the height of the housing layers within the battery frame, leading to low rigidity. This results in instability during the assembly process and makes it impossible for the conveyor lines to support heavy battery packs. Furthermore, when the housing layer height of some battery frames is insufficient, automated assembly of the battery packs using conveyor lines is not feasible.

[0003] Therefore, there is a need to provide a conveyor line to solve the technical problems of low rigidity caused by the structural size design of the conveyor line being limited by the height of the housing layer, and the inability to automatically assemble the battery frame due to insufficient height of the housing layer. Utility Model Content

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a conveyor line that can automatically transport battery packs into the battery frame, achieving high assembly efficiency and saving manpower. Furthermore, it can solve the problem that insufficient height of the receiving layer prevents the use of a conveyor line for automatic assembly, reducing the structural size design limitations of the conveyor line due to the height of the receiving layer, thus improving the rigidity of the conveyor line and consequently enhancing the stability of the assembly process.

[0005] This utility model also proposes an automatic assembly equipment having the above-mentioned conveyor line.

[0006] According to a first aspect of the present invention, a conveyor line is used to convey a battery pack into a battery frame. The conveyor line includes: a main body; a conveyor module disposed on the main body and used to convey the battery pack, the conveyor module having a placement surface for placing the battery pack, the placement surface protruding from the main body in an upward direction, a plurality of conveyor modules being arranged at intervals along the extension direction of the main body, at least partially adjacent two conveyor modules defining a clearance space, the clearance space being used to avoid the bottom structure of the receiving layer in the battery frame; and a conveyor drive mechanism disposed on the main body and connected to the conveyor module for driving the conveyor module to move.

[0007] According to the conveyor line of this utility model embodiment, the conveyor line can automatically transport the battery pack into the battery frame, which has high assembly efficiency and saves manpower. Furthermore, by setting the conveyor modules of the conveyor line to be multiple and spaced apart along the length of the conveyor line, a clearance space can be defined between at least some of the adjacent two conveyor modules. This clearance space is used to avoid the bottom structure of the receiving layer in the battery frame. Thus, during the process of transporting the battery pack to the battery frame using the conveyor line, and during the process of assembling the battery pack into the receiving layer of the battery frame using the automatic assembly equipment, the conveyor line can be inserted below the receiving layer and pushed upward, so that part of the conveyor module passes through the bottom of the receiving layer into the receiving layer, so that part of the conveyor line is still located below the receiving layer.

[0008] This reduces the space occupied by the conveyor line in the height of the housing layer, solving the problem of insufficient height of the housing layer preventing the use of conveyor lines for automated assembly. It also reduces the limitations imposed by the height of the housing layer on the structural dimensions of the conveyor line, allowing for a larger thickness in the vertical direction and a larger width. This improves the rigidity of the conveyor line, reduces deformation or shaking during battery pack transport, and makes the battery pack assembly process more stable. Furthermore, a more rigid conveyor line can support heavier battery packs.

[0048] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] The following is for reference. Figures 1-11 The conveyor line 30 according to an embodiment of the present utility model is described.

[0050] Reference Figures 1-4According to the first aspect of the present invention, the conveyor line 30 is used to convey the battery pack 400 into the battery frame 300. The conveyor line 30 includes: a main body 31, a conveying module 33 and a conveying drive mechanism 32.

[0051] A conveying module 33 is mounted on the main line 31 and is used to convey the battery pack 400. The conveying module 33 has a placement surface 3311 for placing the battery pack 400, and the placement surface 3311 protrudes from the main line 31 in an upward direction. A conveying drive mechanism 32 is mounted on the main line 31 and is connected to the conveying module 33 to drive the conveying module 33 to move. There are multiple conveying modules 33, which are arranged at intervals along the extension direction of the main line 31. At least some adjacent conveying modules 33 define a clearance space 35, which is used to avoid the bottom structure 306 of the receiving layer 301 in the battery frame 300, which is used to receive the battery pack 400.

[0052] The battery frame 300 has multiple receiving layers 301 arranged sequentially in a vertical direction. A battery pack 400 is received within each receiving layer 301. Each receiving layer 301 can receive one or more battery packs 400. When multiple battery packs 400 are received in each receiving layer 301, the multiple battery packs 400 received in each layer can be arranged along a first direction, which is perpendicular to the vertical direction. At least one side of each receiving layer 301 of the battery frame 300 along the first direction is open, so that the battery pack 400 can enter the receiving layer 301 through the opening 303. A conveyor line 30 for conveying the battery pack 400 can also be inserted into the receiving layer 301 through the side opening 303. At least a portion of the bottom surface of the receiving layer 301 has a clearance opening 304 for avoiding the conveyor line 30. The battery frame 300 has multiple layers 301, which are arranged from top to bottom as the first to the Nth layer 301, where N≥2 and N is an integer.

[0053] Optionally, reinforcing brackets 308 can be provided on both sides of the battery frame 300 along the first direction. The reinforcing brackets 308 can be "X" shaped, and can improve the structural strength and rigidity of the battery frame 300. The reinforcing brackets 308 can be detachably installed on the battery frame 300. Before the conveyor line 30 is inserted into the battery frame 300, the battery frame 300 can be removed from the battery frame 300 so that the conveyor line 30 can be smoothly inserted into the battery frame 300. After the conveyor line 30 is separated from the battery frame 300, the reinforcing brackets 308 can be reinstalled on the battery frame 300.

[0054] For example, refer to Figure 5 , Figure 9 and Figure 10 The process of transporting the battery pack 400 to the battery frame 300 using the conveyor line 30 may include the following steps:

[0055] Once the conveyor line 30 is in the first position, place the battery pack 400 on the conveyor line 30.

[0056] The conveyor line 30 transports the battery pack 400 toward the assembly position in a direction close to the battery frame 300;

[0057] The conveyor line 30 is raised to a height position matching the Mth accommodating layer 301;

[0058] The conveyor line 30 moves to the second position along the first direction (refer to the e1 direction in the attached figure) so that the first conveying segment 3a of the conveyor line 30 is inserted into the battery frame 300 along the first direction and is located below the Mth receiving layer 301, and the second conveying segment 3b of the conveyor line 30 is located outside the battery frame 300, 1≤M≤N and M is an integer, and the second conveying segment 3b and the first conveying segment 3a are arranged sequentially along the first direction;

[0059] The conveyor line 30 moves upward so that the placement surface 3311 of the conveyor line 30 protrudes upward from the support surface 302 of the Mth receiving layer 301 to a preset protrusion height. Part of the conveyor line 30 is located below the Mth receiving layer 301. The placement surface 3311 of the conveyor line 30 and the support surface 302 of the Mth receiving layer 301 are both used to place and support the battery pack 400.

[0060] The conveyor line 30 transports the battery pack 400 placed on the second conveyor section 3b to the first conveyor section 3a, so as to transport the battery pack 400 to a preset position in the Mth receiving layer 301;

[0061] The conveyor line 30 moves downward to transfer the battery pack 400 to the support surface 302 of the M receiving layer 301;

[0062] The conveyor line 30 moves along the second direction (refer to direction e2 in the attached figure) to the first position to separate from the battery frame 300.

[0063] The conveying modules 33 of the conveying line 30 are arranged in multiple intervals along the extension direction of the main body 31, and at least some adjacent two conveying modules 33 are separated by a clearance space 35 for avoiding the bottom structure 306 of the receiving layer 301. In this way, when the conveying line 30 moves upward to the point where the placement surface 3311 of the conveying line 30 protrudes upward from the support surface 302 of the receiving layer 301 to a preset protrusion height, interference between the conveying modules 33 and the battery frame 300 can be avoided, ensuring that the conveying line 30 moves upward as a whole to the set height position.

[0064] For example, in some embodiments, the bottom structure 306 of the receiving layer 301 may include a reinforcing beam 307, which may extend in a third direction. The reinforcing beam 307 may be used to strengthen the structural strength and rigidity of the battery frame 300 and reduce the deformation and sway of the battery frame 300. When the conveyor line 30 moves upward so that the placement surface 3311 of the conveyor line 30 protrudes upward from the support surface 302 of the receiving layer 301 to a predetermined protrusion height, at least a portion of the reinforcing beam 307 on the bottom surface of the receiving layer 301 may be accommodated within the aforementioned clearance space 35.

[0065] According to the conveyor line 30 of this utility model embodiment, the conveyor line 30 can automatically convey the battery pack 400 into the battery frame 300, which has high assembly efficiency and saves manpower. Furthermore, by setting the conveyor modules 33 of the conveyor line 30 to be multiple and spaced apart along the length direction of the conveyor line 30, a clearance space 35 can be defined between at least some of the adjacent two conveyor modules 33. The clearance space 35 is used to avoid the bottom structure 306 of the receiving layer 301 in the battery frame 300. Thus, during the process of conveying the battery pack 400 into the battery frame 300 using the conveyor line 30, and during the process of assembling the battery pack 400 into the receiving layer 301 of the battery frame 300 using the automatic assembly equipment 100, the conveyor line 30 can be inserted below the receiving layer 301 and pushed upwards, so that part of the conveyor module 33 passes through the bottom of the receiving layer 301 into the receiving layer 301, so that part of the conveyor line 30 is still located below the receiving layer 301.

[0066] This reduces the space occupied by the conveyor line 30 in the height of the housing layer 301, solving the problem that the insufficient height of the housing layer 301 prevents the use of the conveyor line 30 for automatic assembly. It also reduces the limitations imposed by the height of the housing layer 301 on the structural dimensions of the conveyor line 30, allowing for a larger thickness in the vertical direction and a larger width. This improves the rigidity of the conveyor line 30, reduces deformation or shaking during the transport of the battery pack 400, and makes the assembly process of the battery pack 400 more stable. Furthermore, the more rigid conveyor line 30 can support the heavier battery pack 400.

[0067] According to some embodiments of this utility model, at least some of the conveying modules 33 are detachably mounted on the main line body 31. For example, some of the conveying modules 33 may be detachable, or all of the conveying modules 33 may be detachable. The detachable conveying modules 33 can be mounted on the main line body 31 using fasteners. By making at least some of the conveying modules 33 detachable, the arrangement of the conveying modules 33 can be made more flexible, and conveying modules 33 of different specifications and sizes can be replaced as needed. For example, conveying modules 33 of different lengths can be replaced as needed. This allows for more flexible positioning of the aforementioned clearance space 35, enabling better adaptation to different battery frames 300.

[0068] According to some embodiments of this utility model, refer to Figures 1-3 The width of the main body 31 is greater than the width of the conveying module 33. The widths of both the main body 31 and the conveying module 33 refer to the dimensions in a third direction (refer to direction e3 in the attached diagram), which intersects the vertical direction and is perpendicular to the first direction. By including the main body 31 and the conveying module 33 disposed on the main body 31 in the conveying line 30, and by making the main body 31 wider, the rigidity of the conveying line 30 is improved. This reduces deformation or shaking during the conveying of the battery pack 400, making the conveying process of the battery pack 400 more stable.

[0069] For example, when the conveyor line 30 moves upward so that the placement surface 3311 of the conveyor line 30 protrudes upward from the support surface 302 of the Mth receiving layer 301 to a preset protrusion height, the main line body 31 is located below the Mth receiving layer 301. This allows the wider main line body 31 to be located in the Mth receiving layer 301, while allowing the narrower conveyor module 33 to pass upward through the clearance opening 304 on the bottom surface of the Mth receiving layer 301. This reduces the vertical space occupied by the conveyor line 30 in the Mth receiving layer 301, while allowing the narrower conveyor module 33 to pass through the clearance opening 304 on the bottom surface of the Mth receiving layer 301 more smoothly. This reduces the probability of interference with the battery frame 300 during the upward movement of the conveyor line 30 until the placement surface 3311 of the conveyor line 30 protrudes upward from the support surface 302 of the Mth receiving layer 301 to a preset protrusion height.

[0070] According to some embodiments of this utility model, refer to Figure 1 and Figure 2The position of the conveying module 33 is adjustable along the extension direction of the main line 31. By making the position of the conveying module 33 adjustable along the extension direction of the main line 31, the position setting of the conveying module 33 can be more flexible. This also allows for more flexible positioning of the aforementioned clearance space 35, enabling better adaptation to different battery frames 300. For example, the position of the conveying module 33 can be adjusted according to the structure of different battery frames 300 to avoid interference between the conveying line 30 and the battery frame 300 when they are in contact.

[0071] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The conveying module 33 has mounting lugs 334 on both sides along the width direction of the main line body 31. Multiple mounting holes 312 are provided at both ends of the main line body 31 along its width direction. These mounting holes 312 at the same end of the main line body 31 are spaced apart along its extension direction. The mounting lugs 334 can selectively connect to a portion of the mounting holes 312 to adjust the position of the conveying module 33 along the extension direction of the main line body 31. When installing the conveying module 33 onto the main line body 31, it can be connected to a portion of the mounting holes 312 on the main line body 31 via the mounting lugs 334. For example, the mounting lugs 334 can have connecting holes 335, and fasteners can be inserted through the connecting holes 35 and the mounting holes 312 to install the conveying module 33 onto the main line body 31.

[0072] Furthermore, by selectively connecting the mounting lug 334 to a portion of the multiple mounting holes 312, when installing the conveyor module 33 onto the main line body 31, a portion of the mounting holes 312 can be selected according to the required installation position of the conveyor module 33. By selecting mounting holes 312 at different positions as needed, the conveyor module 33 can be installed in the required position. When it is necessary to adjust the position of the conveyor module 33, the fasteners can be unscrewed to move the conveyor module 33 to the required position, and then the fasteners can be used to fix it.

[0073] The connecting hole 335 on the mounting lug 334 can be an elongated hole extending along the length of the main body 31.

[0074] According to some embodiments of this utility model, refer to Figure 1 and Figure 2Multiple mounting plates 311 are provided at both ends of the main body 31 in the width direction. Multiple mounting plates 311 located at the same end in the width direction of the main body 31 are spaced apart along the extension direction of the main body 31. Each mounting plate 311 is provided with multiple mounting holes 312 spaced apart along the extension direction of the main body 31. Each mounting lug 334 is connected to one of the mounting plates 311, and each mounting lug 334 can selectively connect to some of the mounting holes 312 on the mounting plate 311. The mounting plate 311 and the main body 31 are independently molded parts. By providing multiple mounting plates 311 spaced apart along the extension direction of the main line body 31, each mounting plate 311 has mounting holes 312 for mounting the conveyor module 33. Since the mounting plates 311 and the main line body 31 are independently molded parts, there is no need to directly drill holes in the main line body 31, reducing the impact on its rigidity and ensuring its rigidity and structural strength. Furthermore, the required number of mounting plates 311 can be installed on the main line body 31 as needed, or the mounting plates 311 can be fixed at desired positions on the main line body 31. This allows for more flexible structural design of the conveyor module and helps reduce production costs. Each mounting lug 334 can selectively connect to a portion of the mounting holes 312 on the mounting plate 311. Depending on the installation position of the conveyor module 33, each mounting lug 334 can select a portion of the mounting holes 312 on the mounting plate 311. By selecting mounting holes 312 at different positions on the mounting plate 311 as needed, the conveyor module 33 can be installed in the required position.

[0075] For example, when it is necessary to install the conveyor module 33 at a set position on the main line body 31, the conveyor module 33 can be placed at a fixed installation position on the main line body 31, so that the multiple mounting lugs 334 of the conveyor module 33 correspond one-to-one with the parts of the mounting plates 311 on the main line body 31. Each mounting lug 334 is connected to a part of the mounting hole 312 on a corresponding mounting plate 311. The position of the conveyor module 33 can be adjusted as needed so that the mounting lugs 33 are connected to the parts of the mounting holes 312 on a corresponding mounting plate 311, thereby allowing the conveyor module 33 to be installed on the main line body 31.

[0076] The mounting plate 311 can be welded and fixed to the main body 31.

[0077] According to some embodiments of this utility model, refer to Figures 1-3The conveying module 33 includes a belt conveyor mechanism 331. By configuring the conveying module 33 to include the belt conveyor mechanism 331, the adaptability of the conveyor line 30 can be enhanced. The battery pack 400 is placed on the belt of the conveyor line 30. When the conveying module 33 moves, the friction between the belt and the battery pack 400 can be used to drive the battery pack 400 to move. This allows the conveyor line 30 to adapt to battery packs 400 of different sizes.

[0078] According to some embodiments of this utility model, refer to Figures 1-3 Each conveying module 33 includes a connecting shaft 332 and two belt conveyor mechanisms 331. The two belt conveyor mechanisms 331 of each conveying module 33 are located at both ends of the main line body 31 in the width direction. The connecting shaft 332 extends along the width direction of the main line body 31. The two belt conveyor mechanisms 331 are respectively connected to both ends of the connecting shaft 332. The pulleys of the two belt conveyor mechanisms 331 can be sleeved on the connecting shaft 332 and fixed relative to the connecting shaft 332. The conveying drive mechanism 32 is connected to the connecting shaft 332 in a driving connection. Thus, when the conveying line 30 needs to convey the battery pack 400 in the first direction, the conveying drive mechanism 32 drives the connecting shaft 332 to rotate around its own axis, thereby driving the two belt conveyor mechanisms 331 connected to the connecting shaft 332 to move, and in turn driving the battery pack 400 placed on the belt conveyor mechanism 331 to move in the first direction.

[0079] According to some embodiments of this utility model, refer to Figures 1-4 Multiple conveying modules 33 are driven by the same conveying drive mechanism 32. By having multiple conveying modules 33 driven by the same conveying drive mechanism 32, the number of conveying drive mechanisms 32 used to drive the movement of the conveying modules 33 can be reduced, costs can be reduced, and it is also beneficial to make the multiple conveying modules 33 move more synchronously.

[0080] According to some embodiments of this utility model, refer to Figures 1-4The conveying drive mechanism 32 includes a conveying motor 321, multiple second drive shafts 322, and multiple belt drive mechanisms 323. The multiple second drive shafts 322 are arranged at intervals along the extension direction of the main line body 31, and each second drive shaft 322 extends along the width direction of the main line body 31. Adjacent second drive shafts 322 are connected by a belt drive mechanism 323. The conveying motor 321 is connected to one of the second drive shafts 322. Each conveying module 33 corresponds to one second drive shaft 322 and is connected to the corresponding second drive shaft 322. The conveying motor 321 can be located at one end of the main line body 31 along the second direction. The second drive shaft 322 closest to the conveying motor 321 among the multiple second drive shafts 322 is connected to the output end of the conveying motor 321. For example, the conveying motor 321 and one of the second drive shafts 322 can be connected by a belt drive mechanism 323 or a chain drive mechanism.

[0081] When the conveying drive mechanism 32 drives the conveying module 33 to move, the conveying motor 321 works and drives the second transmission shaft 322 connected to it to rotate around its own axis. Since the two adjacent second transmission shafts 322 are connected by a belt transmission mechanism 323, the second transmission mechanism connected to the conveying motor 321 drives the other second transmission shafts 322 to rotate around their own axis through the belt transmission mechanism 323. The other second transmission shafts 322 drive the corresponding conveying module 33 to move, thereby driving the battery pack 400 placed on the conveying module 33 to move along the first direction.

[0082] According to some embodiments of this utility model, refer to Figures 1-4 Each conveying module 33 includes a connecting shaft 332 and two belt conveying mechanisms 331. The two belt conveying mechanisms 331 of each conveying module 33 are located at both ends of the main line body 31 in the width direction. The connecting shaft 332 extends along the width direction of the main line body 31, and the two belt conveying mechanisms 331 are respectively connected to both ends of the connecting shaft 332. A second gear 3221 is provided on the second transmission shaft 322 corresponding to the conveying module 33. The conveying module 33 also includes a third gear 333, which is located on the connecting shaft 332 and meshes with the second gear 3221.

[0083] When the conveyor line 30 needs to convey the battery pack 400 along the first direction, the conveyor drive mechanism 32 drives the conveyor module 33 to move, the conveyor motor 321 works, and the conveyor motor 321 drives the second drive shaft 322 connected to it to rotate around its own axis. Since the two adjacent second drive shafts 322 are connected by a belt drive mechanism 323, the second drive mechanism connected to the conveyor motor 321 drives the other second drive shafts 322 to rotate around their own axes through the belt drive mechanism 323. The second drive shaft 322 drives the second gear 3221 set on the second drive shaft 322 to rotate. Through the meshing of the second gear 3221 and the third gear 333, the connecting shaft 332 is driven to rotate around its own axis, thereby driving the two belt conveyor mechanisms 331 connected to the connecting shaft 332 to move, and thus driving the battery pack 400 placed on the conveyor module 33 to move along the first direction.

[0084] According to some embodiments of this utility model, refer to Figure 1 The conveyor line 30 also includes at least one set of conveyor rollers 341 34, which are spaced apart from the conveyor module 33 along the extension direction of the main line body 31. Each set of conveyor rollers 341 includes multiple conveyor rollers 341 spaced apart along the extension direction of the main line body 31. Each conveyor roller 341 extends along the width direction of the main line body 31 and is used to convey and support the battery pack 400. The conveyor rollers 341 can be unpowered conveyor rollers 341. At least some adjacent conveyor rollers 341 in the same set of conveyor rollers 341 34 define a clearance space 35, and the receiving layer 301 is used to receive the battery pack 400. By including the conveyor module 33 and unpowered conveyor rollers 341 in addition to the conveyor line 30, the structural configuration of the conveyor line 30 is more flexible, and the clearance space 35 on the conveyor line 30 is also more flexible, allowing for better adaptation to different battery frames 300.

[0085] For example, a bottom structure 306 for avoiding the receiving layer 301 in the battery frame 300 can also be defined between the conveying roller group 341 and the adjacent conveying module 33.

[0086] According to some embodiments of this utility model, at least some of the conveyor rollers 341 are detachably mounted on the main line body 31. For example, some of the conveyor rollers 341 may be detachable, or each conveyor roller 341 may be detachable. By making some of the conveyor rollers 341 detachable, depending on the specific structure of the battery frame 300, some of the conveyor rollers 341 can be selectively removed to create clearance space 35 for the battery frame 300. This further makes the position and size of the clearance space 35 on the conveyor line 30 more flexible and can better match and adapt to different battery frames 300.

[0087] Reference Figures 5-8The automatic assembly equipment 100 according to the second aspect of the present invention includes: an equipment frame 10, a lifting and conveying unit 20, and a lifting drive mechanism 43.

[0088] The lifting and conveying unit 20 is mounted on the equipment frame 10. The lifting and conveying unit 20 includes a lifting frame 21, a conveyor line 30, and a horizontal drive mechanism 41. The conveyor line 30 and the horizontal drive mechanism 41 are both mounted on the lifting frame 21. The lifting drive mechanism 43 is mounted on the equipment frame 10 and is connected to the lifting frame 21. The lifting drive mechanism 43 is used to drive the lifting and conveying unit 20 to move up and down, which also allows the conveyor line 30 to move up and down.

[0089] A conveyor line 30 is used to convey the battery pack 400, and a horizontal drive mechanism 41 is connected to the conveyor line 30. The horizontal drive mechanism 41 is used to drive the conveyor line 30 to move along a first direction (e.g., referring to direction e1 in the figure) or a second direction (e.g., referring to direction e2 in the figure) to engage or disengage with the battery frame 300. The conveying direction of the conveyor line 30 is consistent with the first direction, which is perpendicular to the vertical direction, and the second direction is opposite to the first direction. For example, the horizontal drive mechanism 41 can drive the conveyor line 30 to move along the first direction to engage with the battery frame 300; the horizontal drive mechanism 41 can also drive the conveyor line 30 to move along the second direction to disengage with the battery frame 300. The conveyor line 30 has a first position and a second position along the first direction. When the conveyor line 30 is in the first position, it is disengaged from the battery frame 300; when the conveyor line 30 is in the second position, it engages with the battery frame 300.

[0090] The following is a brief description of the assembly process within the battery frame 300 when assembling the battery pack 400 using the automatic assembly equipment 100 of this utility model embodiment.

[0091] Among them, reference Figure 5 , Figure 9 as well as Figure 10 The process of assembling the battery pack 400 in each receiving layer 301 using the aforementioned automated assembly equipment 100 may include the following steps:

[0092] Once the conveyor line 30 is in the first position, place the battery pack 400 on the conveyor line 30.

[0093] The conveyor line 30 transports the battery pack 400 toward the assembly position in a direction close to the battery frame 300;

[0094] The lifting drive mechanism 43 drives the lifting frame 21 to rise and fall, thereby driving the conveyor line 30 to rise and fall to a height position that matches the Mth accommodating layer 301;

[0095] The horizontal drive mechanism 41 drives the conveyor line 30 to move along the first direction to the second position, so that the first conveyor section 3a of the conveyor line 30 is inserted into the battery frame 300 along the first direction and is located below the Mth receiving layer 301, and the second conveyor section 3b of the conveyor line 30 is located outside the battery frame 300, 1≤M≤N and M is an integer, and the second conveyor section 3b and the first conveyor section 3a are arranged sequentially along the first direction;

[0096] The lifting drive mechanism 43 drives the lifting frame 21 to move upward, which in turn drives the conveyor line 30 to move upward, so that the placement surface 3311 of the conveyor line 30 protrudes upward from the support surface 302 of the Mth receiving layer 301 to a preset protrusion height. Part of the conveyor line 30 is located below the Mth receiving layer 301. The placement surface 3311 of the conveyor line 30 and the support surface 302 of the Mth receiving layer 301 are both used to place and support the battery pack 400.

[0097] The conveyor line 30 transports the battery pack 400 placed on the second conveyor section 3b to the first conveyor section 3a, so as to transport the battery pack 400 to a preset position in the Mth receiving layer 301;

[0098] The lifting drive mechanism 43 drives the lifting frame 21 to move downward, which in turn drives the conveyor line 30 to move downward, so as to transfer the battery pack 400 to the support surface 302 of the M receiving layer 301.

[0099] The horizontal drive mechanism 41 drives the conveyor line 30 to move along the second direction to the first position to separate from the battery frame 300.

[0100] According to the automatic assembly equipment 100 of this utility model embodiment, by setting the above-mentioned conveyor line 30, the battery pack 400 can be automatically conveyed into the battery frame 300, which has high assembly efficiency and saves manpower; in addition, it can solve the problem that the conveyor line 30 cannot be used for automatic assembly due to insufficient layer height of the receiving layer 301, which can reduce the structural size design of the conveyor line 30 being limited by the layer height of the receiving layer 301, which is conducive to improving the rigidity of the conveyor line 30, thereby improving the stability of the assembly process.

[0101] According to some embodiments of this utility model, refer to Figures 5-8The lifting drive mechanism 43 includes a lifting motor 431, a first drive shaft 432, a support shaft, and two first chain drive mechanisms 434. The lifting motor 431 and the first drive shaft 432 are both located above the lifting conveying unit 20, and the support shaft is located below the lifting conveying unit 20. Both the first drive shaft 432 and the support shaft extend along a third direction and are rotatably mounted on the equipment frame 10 around their own axes. The width direction of the conveyor line 30 is consistent with the third direction (e.g., refer to direction e3 in the attached figure). The lifting motor 431 is connected to the first drive shaft 432 to drive its rotation. The two sprockets of each first chain drive mechanism 434 can be arranged at intervals in the vertical direction. The first drive shaft 432 connects to the upper ends of the two first chain drive mechanisms 434, and the support shaft connects to the lower ends of the two first chain drive mechanisms 434. Each first chain drive mechanism 434 has an upper sprocket mounted on and fixed relative to the first drive shaft 432, and a lower sprocket mounted on and fixed relative to the support shaft. Each first chain drive mechanism 434 includes a first chain, with its two ends spaced apart along its length, and both ends connected to the lifting frame 21.

[0102] The output end of the lifting motor 431 can be connected to the first drive shaft 432 via a belt drive mechanism 323 or a chain drive mechanism. The lifting motor 431 can be a servo motor.

[0103] In the above embodiment, when the lifting drive mechanism 43 drives the lifting frame 21 to move up and down, the lifting motor 431 works, and the lifting motor 431 drives the first transmission shaft 432 to rotate around its own central axis. The first transmission shaft 432 drives the two first chain transmission mechanisms 434 to move, thereby driving the lifting frame 21 to move up or down, which in turn drives the conveyor line 30 to move up or down.

[0104] According to some embodiments of the present invention, referring to Figures 5-8 The automatic assembly equipment 100 includes a fall arrestor 12, which is mounted on the equipment frame 10 and located above the lifting and conveying unit 20. The fall arrestor 12 is connected to the lifting frame 21. When the lifting and conveying unit 20 descends at a normal speed, the fall arrestor 12 does not prevent the lifting frame 21 from moving downward. When the lifting and conveying unit 20 suddenly accelerates downward, the fall arrestor can prevent the lifting frame 21 from moving downward, thereby preventing the lifting and conveying unit 20 from malfunctioning and suddenly falling.

[0105] According to some embodiments of this utility model, refer to Figures 5-8The horizontal drive mechanism 41 includes a horizontal drive motor 411, a rack, and a first gear. The horizontal drive motor 411 is located at the bottom of the lifting frame 21, and the first gear is located at the output end of the horizontal drive motor 411. The rack is located at the bottom of the conveyor line 30 and extends along the length of the conveyor line 30. The first gear meshes with the rack. When the horizontal drive motor 411 is working, it can drive the first gear to rotate, which in turn drives the rack to move in a first direction or a second direction, thereby driving the conveyor line 30 to move in the first direction or the second direction. The horizontal drive motor 411 can be a servo motor.

[0106] According to some embodiments of this utility model, refer to Figures 5-8 The lifting and conveying unit 20 includes a separation and buffer mechanism 50, which is disposed on the lifting frame 21. The separation and buffer mechanism 50 is used to lift the battery pack 400 placed on the conveyor line 30 upward away from the conveyor line 30 before the conveyor line 30 and the battery frame 300 are engaged. The separation and buffer mechanism 50 is also used to transfer the battery pack 400 downward onto the conveyor line 30 when the conveyor line 30 and the battery frame 300 are engaged and before the conveyor line 30 conveys the battery pack 400 into the battery frame 300.

[0107] The separation buffer mechanism 50 is used to lift the battery pack 400 placed on the conveyor line 30 upwards away from the conveyor line 30 before the conveyor line 30 mates with the battery frame 300. After the battery pack 400 is separated from the conveyor line 30 by the separation mechanism, it is convenient to insert the conveyor line 30 into the battery frame 300 along the first direction. During the process of driving the conveyor line 30 to insert into the battery frame 300 along the first direction, the conveyor line 30 is in an unloaded state, and the requirement for driving force is low, which can reduce energy loss. It can also reduce the impact of the conveyor line 30 on the battery pack 400 during its movement along the first direction. For example, it may cause the position of the battery pack 400 to change, resulting in inaccurate subsequent assembly of the battery pack 400, which helps to ensure the accuracy of the battery pack 400 assembly.

[0108] The separation buffer mechanism 50 is also used to transfer the battery pack 400 on the conveyor line 30 downwards onto the conveyor line 30 when the conveyor line 30 is engaged with the battery frame 300 and before the conveyor line 30 conveys the battery pack 400 into the battery frame 300. This facilitates the downward transfer of the battery pack 400 temporarily stored on the separation buffer mechanism 50 onto the conveyor line 30, making it easier for the subsequent conveyor line 30 to convey the battery pack 400 into the battery frame 300.

[0109] For example, after the conveyor line 30 moves upward so that the placement surface 3311 of the conveyor line 30 protrudes upward from the support surface 302 of the Mth receiving layer 301 to a preset protrusion height, the separation buffer mechanism 50 moves the temporarily stored battery pack 400 downward to be supported on the second conveying section 3b of the conveyor line 30. By moving the conveyor line 30 upward until the placement surface 3311 of the conveyor line 30 protrudes upward from the support surface 302 of the Mth receiving layer 301 to a preset protrusion height, and then placing the battery pack 400 on the second conveying section 3b of the conveyor line 30, the conveyor line 30 is in an unloaded state during the upward movement of the conveyor line 30, which requires less driving force, thus reducing energy loss. It also reduces the impact of the upward movement of the conveyor line 30 on the battery pack 400, such as the potential for changes in the position of the battery pack 400, which could lead to inaccurate subsequent assembly of the battery pack 400. This helps to ensure the accuracy of the battery pack 400 assembly.

[0110] According to some embodiments of this utility model, refer to Figures 5-8 The separation buffer mechanism 50 includes a separation buffer motor 51 and two buffer support plates 55. The two buffer support plates 55 are located on both sides of the width direction of the conveyor line 30 and are used to buffer and support the battery pack 400. The separation buffer motor 51 is driveably connected to the buffer support plates 55 to drive the buffer support plates 55 to move in the up and down direction.

[0111] When the battery pack 400 is placed on the conveyor line 30, the two buffer support plates 55 are located below the battery pack 400. When the separation buffer mechanism 50 needs to lift the battery pack 400 supported on the conveyor line 30 upwards, the separation buffer motor 51 drives the two buffer support plates 55 upwards until they contact the bottom surface of the battery pack 400. The separation buffer motor 51 continues to drive the two buffer support plates 55 upwards, thereby moving the battery pack 400 upwards until it separates from the conveyor line 30. Before the separation buffer mechanism 50 transfers the battery pack 400 onto the conveyor line 30, the battery pack 400 is temporarily supported on the two buffer support plates 55.

[0112] When the separation buffer mechanism 50 needs to transfer the battery pack 400, which is temporarily supported on the two buffer support plates 55, downward to the conveyor line 30, the separation buffer motor 51 drives the two buffer support plates 55 to move downward until the bottom surface of the battery pack 400 contacts the conveyor line 30. Then, the separation buffer motor 51 continues to drive the two buffer support plates 55 to move downward, thereby separating the two buffer support plates 55 from the battery pack 400 and transferring the battery pack 400 to the conveyor line 30.

[0113] According to some embodiments of this utility model, refer to Figures 5-8The separation buffer mechanism 50 includes a fourth gear 52, a second chain 531 transmission mechanism 53, and two first lead screw mechanisms 54. Each first lead screw mechanism 54 includes a first lead screw and a first nut seat. The first lead screw extends vertically. The separation buffer motor 51 is located on the top of the lifting frame 21. The second chain 531 transmission mechanism 53 can be arranged along the width of the conveyor line 30. The two sprockets of the second chain 531 transmission mechanism 53 are respectively sleeved on the upper ends of the first lead screws of the two first lead screw mechanisms 54 and fixed relative to the first lead screws. The second chain 531 transmission mechanism 53 includes a second chain 531. The fourth gear 52 is located at the output end of the separation buffer motor 51 and meshes with the second chain 531. The first lead screws of the two first lead screw mechanisms 54 are connected by transmission through the second chain 531 transmission mechanism 53. The buffer support plate 55 is fixed to the first nut seat.

[0114] When the separating buffer motor 51 drives the two buffer support plates 55 to move vertically, the separating buffer motor 51 drives the fourth gear 52 to rotate. Since the fourth gear 52 meshes with the second chain 531 of the second chain 531 transmission mechanism 53, it can drive the second chain 531 transmission mechanism 53 to move, which in turn drives the first lead screws of the two first lead screw mechanisms 54 to rotate around their own axes. The rotating first lead screws drive the first nut seats to move vertically. The first nut seats drive the buffer support plates 55 connected to them to move vertically.

[0115] According to some embodiments of this utility model, refer to Figures 9-11 The lifting and conveying unit 20 includes a centering mechanism 57, which is located on the lifting frame 21 and is used to center the battery pack 400 supported on the buffer support plate 55. After the separation buffer mechanism 50 lifts the battery pack 400 upward away from the conveyor line 30, the centering mechanism 57 can adjust the position of the battery pack 400 in the width direction of the conveyor line 30 so that the battery pack 400 is in a centered position. In this way, when the separation buffer mechanism 50 subsequently transfers the battery pack 400 downward to the conveyor line 30, the battery pack 400 can be positioned in a centered position in the width direction of the conveyor line 30. This ensures that when the conveyor line 30 subsequently conveys the battery pack 400 into the battery frame 300, the battery pack 400 is positioned in a preset position within the battery frame 300, preventing the battery pack 400 from being misaligned in the width direction of the conveyor line 30.

[0116] In addition, after the battery pack 400 is lifted upward away from the conveyor line 30 by the separation buffer mechanism 50, the position of the battery pack 400 in the width direction of the conveyor line 30 is adjusted by the centering mechanism 57, instead of adjusting the position of the battery pack 400 in the width direction of the conveyor line 30 directly on the conveyor line 30. This can reduce the difficulty of adjustment and improve the accuracy of adjustment.

[0117] According to some embodiments of this utility model, refer to Figure 10 The upper surface of the buffer support plate 55 includes a buffer support surface 302 for supporting the battery pack 400. The buffer support surface 302 is a self-lubricating surface. When the battery pack 400 is supported on the buffer support plate 55, the bottom surface of the battery pack 400 supports and contacts the buffer support surface 302 of the buffer support plate 55. By setting the buffer support surface 302 as a self-lubricating surface, the friction between the battery pack 400 and the buffer support plate 55 can be further reduced during the alignment process of the battery pack 400 supported on the buffer support plate 55 using the alignment mechanism 57 described above. This further reduces the difficulty of aligning and adjusting the battery pack 400 and improves the accuracy of the alignment.

[0118] According to some embodiments of this utility model, refer to Figures 5-8 The centering mechanism 57 includes a centering motor 571 and multiple centering adjustment components 572, which are divided into two groups located on both sides of the width direction of the conveyor line 30. Each centering adjustment component 572 includes an adjustment rod and an adjustment swing arm. The adjustment swing arm is connected to the adjustment rod and is used to contact the battery pack 400. One end of the adjustment swing arm is connected to the adjustment rod, and the other end is used to contact the battery pack 400 to push the battery pack 400 to move, thereby adjusting the position of the battery pack 400. The adjustment rod extends vertically and passes through the buffer support plate 55. The adjustment rod is rotatable horizontally relative to the buffer support plate 55, and the buffer support plate 55 is movable vertically relative to the adjustment rod. This design makes the structure compact and avoids interference between the adjustment rod and the buffer support plate 55. The centering motor 571 is driveably connected to the adjusting rod to drive the centering adjusting member 572 to rotate horizontally, thereby pushing the battery pack 400 to the centering position.

[0119] When the centering mechanism 57 is working, the centering motor 571 drives multiple centering adjustment components 572 to rotate in the horizontal direction, and the adjustment arm swings in the horizontal direction, thereby pushing the battery pack 400. The multiple centering adjustment components 572 together push the battery pack 400 to the centering position.

[0120] According to some embodiments of this utility model, refer to Figures 9-11 The centering mechanism 57 includes a third chain drive mechanism 575 and two fourth chain drive mechanisms 576. The third chain drive mechanism 575 is arranged along the width direction of the conveyor line 30, and the two fourth chain drive mechanisms 576 are located on opposite sides of the width direction of the conveyor line 30. The centering motor 571 is located between the two fourth chain drive mechanisms 576 and is located on one side of the third chain drive mechanism 575 along the second direction.

[0121] Each set of centering adjustment components 572 comprises two components, designated as the first centering adjustment component 572 and the second centering adjustment component 572. The first and second centering adjustment components 572 are arranged along a second direction. The third chain drive mechanism 575 includes a third chain. The centering motor 571 is connected to the third chain via a gear transmission mechanism. The third chain drive mechanism 575 drives two of the first centering adjustment components 572 in the two sets of centering adjustment components 572. Two sprockets of the third chain drive mechanism 575 are respectively mounted on the adjusting rods of the two first centering adjustment components 572 and fixed relative to the adjusting rods. The centering motor 571 drives the third chain drive mechanism 575 to move via the gear transmission mechanism, and the third chain drive mechanism 575 drives the two first centering adjustment components 572 to rotate.

[0122] The fourth chain drive mechanism 576 is connected to the first and second centering adjusters 572 in the same group of centering adjusters 572. For example, a first transmission gear can be installed on the adjusting rod of the first centering adjuster 572, and a second transmission gear can be coaxially installed on a sprocket in the fourth chain drive mechanism 576. The second transmission gear meshes with the first transmission gear. By meshing the second transmission gear with the first transmission gear, each first centering adjuster 572 drives the corresponding fourth chain drive mechanism 576 to move, thereby driving the second centering adjuster 572 to rotate.

[0123] According to some embodiments of this utility model, refer to Figure 5 , Figure 9 and Figure 10 The automatic assembly equipment 100 includes two frame positioning units 80, located on opposite sides of the frame conveying track 200 in the width direction. The frame conveying track 200 extends along a third direction and is used to convey the battery frame 300 to one side of the equipment stand 10 along a first direction. The width direction of the conveying line 30 is consistent with the third direction. Through the conveying track 200, a conveying trolley 201 can travel on it. The battery frame 300 is placed on the conveying trolley 201, and the trolley 201 moves along the conveying track 200 to convey the battery frame 300 to one side of the equipment stand 10 along the first direction, facilitating the subsequent assembly of the battery pack 400 into the battery frame 300.

[0124] When the conveying trolley 201 moves along the conveying track 200 and conveys the battery frame 300 to one side of the equipment stand 10 in the first direction, the battery pack 400 can be supported on two frame positioning units 80. The two frame positioning units 80 can lock the battery frame 300 to prevent it from swinging and to position it precisely.

[0125] According to some embodiments of this utility model, refer to Figures 1-5 The automatic assembly equipment 100 includes a preliminary positioning component, which includes multiple preliminary positioning mechanisms 60. When the conveyor line 30 is in the first position, the multiple preliminary positioning mechanisms 60 are distributed on both sides of the width direction of the conveyor line 30. The upper end of the preliminary positioning mechanism 60 forms a guide positioning surface on the side facing the conveyor line 30. The guide positioning surface is higher than the upper surface of the conveyor line 30. The guide positioning surface is used to guide the battery pack 400 to be placed on the conveyor line 30.

[0126] When the conveyor line 30 is in the first position, the battery pack 400 can be placed on the conveyor line 30. For example, the battery pack 400 can be placed on the conveyor line 30 by manual operation of a lifting device or a main robotic arm. The battery pack 400 can be initially positioned by multiple initial positioning mechanisms 60 of the initial positioning assembly. During the process of placing the battery pack 400 on the conveyor line 30, the battery pack 400 is placed downwards from above the conveyor line 30. During this process, the guide positioning surfaces of the multiple initial positioning mechanisms 60 can guide the battery pack 400 downwards onto the conveyor line 30 and perform initial positioning of the battery pack 400 in the width direction of the conveyor line 30.

[0127] According to some embodiments of this utility model, refer to Figures 1-5 The conveyor line 30 has a first end 36 and a second end 37 disposed opposite to each other along the length direction of the conveyor line 30, for example, the first end 36 and the second end 37 are respectively connected to both sides of the main line body 31 along the length direction. The automatic assembly equipment 100 also includes an auxiliary support 63, which is disposed on one side of the equipment stand 10 along the second direction and is spaced apart from the equipment stand 10. The auxiliary support 63 is used to support the first end 36 of the conveyor line 30 when the conveyor line 30 is in the first position.

[0128] When the conveyor line 30 is in the first position, most of the conveyor line 30 is located on one side of the equipment stand 10 along the second direction.
