As a core component of electric vehicles, the safety of the battery pack is directly related to the vehicle's operational stability and passenger safety. Therefore, strict control over the battery module packaging process is particularly important during battery pack production.

[0003] To ensure the safety and integrity of battery modules and prevent damage during transportation and installation, specialized tooling is typically used during the battery module placement process. However, existing battery module placement tooling suffers from significant design deficiencies. Specifically, the overall structural strength and clamping strength of these tooling devices are insufficiently designed, making it difficult to effectively support and secure the battery modules, resulting in the battery modules or battery packs being easily damaged during placement.

This is primarily due to an inadequately designed clamping mechanism, which fails to stably hold the battery modules, causing them to easily fall or wobble during placement. This design flaw not only impacts the efficiency of placing battery modules into boxes but also increases safety risks during the process, hindering efficient assembly. Utility Model Content

[0057] Example 1

[0058] This embodiment relates to a battery pack assembly system, which aims to improve the assembly efficiency of battery modules by optimizing the structure of the battery pack assembly system.

[0059] In terms of overall structure, Figures 1 to 6As shown, the battery pack assembly system in this embodiment includes a stacking tool 1 for stacking a plurality of battery cells into a module, and a module loading device having a lifting tool 2, and the lifting tool 2 is used to lift the module into the battery pack box.

Each module end pad 102 is located on the extrusion side of the corresponding first extrusion component 101 and is used to abut the module, and each first extrusion component 101 is provided with a plurality of gap portions 103 arranged at intervals.

[0061] The lifting fixture 2 has two clamping parts 2031 that can clamp the module in the length direction of the module. Each clamping part 2031 is provided with multiple claws 2033 arranged at intervals, and at least two claws 2033 are detachably connected to the corresponding module end pads 102.

[0062] When the lifting tool 2 clamps the module in the stacking tool 1, each claw portion 2033 can pass through each gap portion 103 one by one, so that each clamping portion 2031 can abut against the corresponding module end pad 102 through its own multiple claw portions 2033 and clamp the module.

[0063] As configured above, the battery pack assembly system in this embodiment stacks the battery cells into modules through the stacking tool 1 and provides a certain pre-tightening force, and hoists the modules into the battery pack box through the module loading device with the lifting tool 2. The module end pad 102 is arranged to protect the battery cells during the stacking process. By ensuring the even distribution of the pre-tightening force, the claw portion 2033 and the gap portion 103 are matched to enable the module end pad 102 to be set in the stacking tool 1 during stacking and on the lifting tool 2 during lifting, which is convenient for ensuring the safety and stability of the module during the lifting process, thereby helping to improve the use quality of the battery pack assembly system.

[0064] Specifically, in this embodiment, as an exemplary structure, combined with Figures 1 to 4 As shown, the stacking tool 1 of the battery pack assembly system in this embodiment includes a base 104 , a squeezing mechanism 105 provided on the base 104 , and an alignment mechanism 106 provided on the base 104 .

Two extrusion mechanisms 105 are provided at either end of the stacking platform along its length, and each extrusion mechanism 105 includes a first extrusion assembly 101. The placement groove 1041 facilitates the arrangement of battery cells in the stacking tool 1, and the extrusion mechanisms 105 facilitate the stacking of battery cells into modules, resulting in a simple structure and convenient design and implementation.

[0067] Specifically, the spacing dimensions of the gaps 103 between the clamping jaws 1012 can be the same or different, as long as they are compatible with the clamping mechanism 203 of the hoisting tool 2 .

The setting of the insertion holes 1013, the insertion matching holes and the pins facilitates the detachable setting of the module end plate pad, and at the same time facilitates disassembly and assembly, helps to improve disassembly and assembly efficiency, and is conducive to design implementation.

[0069] Each extrusion mechanism 105 includes a first slide rail 1051 provided on the base 104, and a driving component 1052 connected to the first extrusion component 101. The first slide rail 1051 is arranged along the length direction of the stacking table, and the substrate 1011 in the first extrusion component 101 is slidably provided on the first slide rail 1051. Driven by the driving component 1052, the first extrusion component 101 approaches or moves away from the corresponding end of the module in the length direction along the length direction of the stacking table.

[0070] Specifically, the driving assembly 1052 includes a sleeve with an internal thread provided on the base 104, and a transmission shaft passing through and threadedly connected to the sleeve.

[0071] Combine Figures 1 to 4 As shown, in this embodiment, the alignment mechanisms 106 are two arranged on both sides of the stacking platform in the width direction, and the two mechanisms cooperate with each other to squeeze the module in the width direction. The setting of the alignment mechanism 106 enables the two ends of the small surface of the battery cell monomers to be aligned when the battery cell monomers are stacked into a module, thereby ensuring the overall shape of the module formed by stacking the battery cell monomers and facilitating design implementation.

[0072] Specifically, each alignment mechanism 106 includes a second slide rail 1061 provided on the base 104, and a second extrusion assembly 107 slidably provided on the second slide rail 1061, and the second slide rail 1061 is arranged along the width direction of the stacking platform.

The arrangement of the extrusion plate 1072 is convenient for ensuring the overall shape of the module after the battery cells are stacked.

[0073] Specifically, each connecting plate is connected by a connecting rod, and each connecting plate is inserted into the mounting plate 1071. A locking mechanism 1073 is provided between the mounting plate 1071 and the base 104. A position-adjustable abutment plate 1074 is provided on the side of the extrusion plate 1072 facing the stacking platform.

The structure is simple and convenient for design and implementation.

[0074] Combine Figure 1 、 Figure 5 and Figure 6 As shown, the lifting fixture 2 of the battery pack assembly system in this embodiment includes a base 201 , and a pressing mechanism 202 and a clamping mechanism 203 provided on the base 201 .

[0075] Specifically, the clamping mechanism 203 is located below the base 201 and includes two clamping parts 2031 arranged opposite to each other along the length direction of the base 201, and a first driving part 2032 for driving the two clamping parts to move away from each other to clamp the module.

The transmission wheel assembly 2021, driven by the second driving part 2022, can drive the pressing part 2023 to move up and down to press the module through the screw. The setting of the pressing mechanism 202 is convenient for ensuring the overall shape of the battery cells when they are stacked into modules, and avoids the battery cells from arching upward due to the squeezing of the stacking tool 1, so that the pressing mechanism 202 includes the transmission wheel assembly 2021, the second driving part 2022 and the screw, with a simple structure, convenient for the operation of the pressing mechanism 202, and conducive to design implementation.

[0076] In more detail, each clamping portion 2031 has a plurality of claws 2033 arranged at intervals along the width direction of the base 201, and at least two claws 2033 are penetrated by plug-in holes 2034 arranged along the clamping direction, and a plurality of insertion holes are provided on each module end pad 102.

[0077] In addition, a synchronous lifter 204 is provided between the base 201 and the pressing portion 2023. The synchronous lifter 204 includes a plurality of guide posts 2041 that can slide back and forth along the thickness direction of the base 201.

The provision of the synchronous lifter 204 ensures the synchronous lifting and lowering of the pressing portion 2023 during the downward pressing. The arrangement of the hoisting part 205 facilitates the assembly of the hoisting tool 2 on the stacking tool 1 and the lifting of the battery module. The hoisting part 205 includes a hoisting plate 2051 and a hoisting ring 2052 to ensure the structural strength and hoisting strength of the hoisting part 205.

[0078] In addition, the module end pads 102 of the battery pack assembly system in this embodiment are provided with positioning structures for positioning and abutting against the frame of the battery pack box. The setting of the positioning structure on the module end plate pad facilitates the assembly positioning of the battery module in the battery pack, which helps to ensure the assembly accuracy of the battery module.

[0079] Specifically, the positioning structure includes a plurality of through holes 1021 provided on the module end pad 102, and a positioning member inserted into each through hole 1021. Each through hole 1021 is arranged in the height direction of the module end pad 102, and each positioning member is used to be sequentially inserted into the corresponding through hole 1021 and the positioning hole on the frame to form a positioning match between the module end pad 102 and the frame. The positioning member cooperates with the through hole 1021 in the form of setting, and the structure is simple, which is conducive to design and implementation. Of course, the positioning structure can also include a plurality of positioning columns detachably provided at the bottom of the module end pad 102. Each positioning column is used to be inserted into and matched with the positioning hole on the frame. It is only necessary to meet the requirement that it can realize the positioning between the module and the battery pack box when the module is put into the box. In addition, the positioning holes can also be provided on the beam structure inside the battery pack. It is only necessary to arrange the positioning holes according to the corresponding positions of the battery modules in the battery pack box.

[0080] It is worth mentioning that in order to facilitate the detection of the pressure of the battery modules during stacking, the battery pack assembly system in this embodiment is also provided with a pressure sensor. The sensing ends of the pressure sensor are respectively arranged on the contact surfaces of the battery module and the stacking tooling 1, and the lifting tooling 2. Through the setting of the pressure sensor, the pressure changes of the battery modules during stacking can be better monitored, which is beneficial to ensuring the assembly efficiency of the battery modules.

[0081] In addition, combined Figure 2 and Figure 6 As shown, the module loading device also includes a pressure stabilizing tool 3. The pressure stabilizing tool 3 includes a crossbeam 301 located above the lifting tool 2. The crossbeam 301 can be fixed above the lifting tool by a fixed structure (not shown in the figure). The fixed structure can be, for example, a nut and a screw. The crossbeam 301 is used to press the lifting tool 2 when performing the module loading operation, so that the lifting tool 2 maintains a downward pressure on the module for a preset period of time. The setting of the pressure stabilizing tool 3 is convenient for ensuring the pressure of the downward pressure tool on the top of the battery module, avoiding changes in the force of the battery module during the downward pressure process.

[0083] When the battery pack assembly system of this embodiment is used, the large surfaces of the battery cells are first arranged in sequence in the placement groove 1041 of the stacking table, and the module end pad 102 is assembled on the first extrusion component 101. The position of the first extrusion component 101 is adjusted by the driving component 1052 so that the module end pad 102 is squeezed on the two ends of the arranged multiple battery cells facing outwards. By adjusting the alignment mechanism 106, the second extrusion component 107 is squeezed on the other two opposite sides of the battery module. The driving component 1052 is adjusted so that the first extrusion component 101 applies a certain pre-tightening force to the battery module. After the pre-tightening is completed, the lifting tool 2 is lifted to the bottom. Above the seat 104, adjust the position of the clamping mechanism 203 so that the claw 2033 of the clamping mechanism 203 is inserted into the gap 103 of the clamping claw 1012, and adjust the pressing mechanism 202 to press down the top of the battery module. After completion, adjust the positioning pin, assemble the module end pad 102 to the clamping mechanism 203, and lift the lifting tool 2 to the predetermined installation position above the battery pack box. Through the positioning structure, move the battery module from the bottom to the predetermined installation position in the battery pack box, position the beam 301 on the lifting tool 2, adjust the beam 301, and stabilize the battery module for a preset time. After the voltage stabilization is completed, the battery module is assembled in the battery pack box.

[0084] The battery pack assembly system of this embodiment can stack battery cells into battery modules and assemble the battery modules into the battery pack box through the cooperation of the stacking tool 1 and the module loading device. The stacking tool 1 provides pre-tightening force to the battery module, and the lifting tool 2 maintains the pre-tightening force while transferring the battery module to the battery pack box and loading it into the battery pack box. The voltage stabilizing tool 3 stabilizes the battery module for a preset time, thereby completing the stacking and loading process of the battery module. The cooperation of various components improves the assembly efficiency of the battery module.
