Description

Technical Field

[0001] The utility model relates to the technical field of module grouping, and in particular to a battery module packaging steel strip stacking tool. Background Art

[0002] Electric vehicles are powered by an onboard power supply and use motors to drive the wheels. Since their impact on the environment is relatively small compared to traditional vehicles, their prospects are widely optimistic. Currently, due to the need for environmental protection and energy conservation, lightweighting of vehicles has become a trend in the development of automobiles around the world. Lightweighting of vehicles means reducing the curb weight of the vehicle as much as possible while ensuring the strength and safety performance of the vehicle, thereby improving the vehicle's power, reducing energy consumption, and reducing exhaust pollution. The energy storage type low-voltage battery module structure is used in the field of new energy pure electric vehicles. The existing battery module structure includes a cell group, which includes a plurality of parallel stacked cells and a buffer pad placed between the cells. End plates are provided on the front and rear sides of the cell group. The cell group is fastened and fixed by fixings to form a module. The fixings are steel belts. However, when producing and installing battery modules, there is no auxiliary structure for stacking the cells to keep the cells neat, which is not convenient for the subsequent welding process; and because cell stacking takes longer, stacking and extrusion on one tool will affect the overall production efficiency and it is very inconvenient to operate on one tool; and in the prior art, there is no groove for pre-placing the steel belt at the bottom of the battery module, which is inconvenient for installing the steel belt; and the size of the overall tool is too large and not easy to move, and it is not convenient to move the tool together during the production and installation process.

[0003] For example, the patent with patent announcement number CN221668996U discloses an assembly auxiliary tooling for an energy storage type low-voltage battery module structure, which includes battery cells, buffer pads, steel strips, end plates, and aluminum bars; the battery cells are generally lithium battery cells, and the buffer pads are a flame-retardant foam or high-temperature resistant insulating material, which can effectively block the spread of thermal runaway and reduce the expansion force of the lithium battery at the end of its life; the steel strip is a high-strength, high-toughness strip metal; the multiple battery cells are stacked in parallel, and the battery cells are isolated by buffer pads to form a module, and the outside of the module is tightened and fixed by steel strips; the aluminum bar is welded to the module battery cell pole to form a battery system.

[0004] Technical problems to be solved by utility models

[0005] In order to solve the technical problem that the existing steel strip battery module lacks auxiliary structure for tidying up the battery cells, resulting in inconvenient operation and reduced production efficiency, the utility model provides a battery module packaging steel strip stacking tool, which can tidy up the battery modules with battery cells, is easy to operate and improves production efficiency.

[0006] Technical Solution

[0007] In order to solve the above problems, the technical solution provided by the present invention is as follows:

[0008] A battery module packaging steel strip stacking tool, including a connecting bracket, a stacking bracket is provided on the connecting bracket, end plate bracket 1 and end plate bracket 2 are provided at both ends of the stacking bracket, the end plate bracket 1 and end plate bracket 2 are higher than the stacking bracket, the end plate bracket 2 can be fixedly slidably connected to the connecting bracket, and the sliding direction is close to or away from the stacking bracket, a pre-placement groove for accommodating steel strips is provided between the stacking bracket and the end plate bracket 1 and end plate bracket 2, and a side plate bracket is fixedly connected to the side of the connecting bracket.

[0009] The stacking brackets are used to position battery modules. End plate brackets 1 and 2 form a limiter at each end. End plate bracket 2 is slidable and flexible, allowing end plate bracket 2 to be positioned away from the stacking brackets when placing the steel straps. When aligning the battery modules, end plate bracket 2 can be placed against the stacking brackets to create a limiter. End plate fastening blocks are located at each end of the battery module to tension the steel straps, securing the entire battery module together. The end plate fastening blocks form a height limiter with end plate brackets 1 and 2. The top surfaces of end plate brackets 1 and 2 abut against the bottom surfaces of the end plate fastening blocks, creating a height limiter. The steel straps are wrapped around the end plate fastening blocks. This height limiter positions the steel straps in the middle, preventing imbalance and improving the stability of the battery module. Pre-placement slots are used to position the steel straps before installing the packed battery modules, facilitating their installation. Side plate brackets laterally limit the battery module cells, aligning them.

[0010] Optionally, a threaded hole is provided at the bottom of the end plate bracket 2 for fitting with a bolt for fixing, and a sliding groove is provided on the connecting bracket. The bolt fits with the sliding groove and is fixed after being tightened.

[0011] The threaded hole matches the bolt, and the bolt passes through the sliding groove. The tail of the bolt is larger than the width of the sliding groove for clamping. The bolt needs to be loosened when the end plate bracket 2 needs to slide, and tightened when it needs to be fixed.

[0012] Optionally, a protruding bottom bracket is fixed to the bottom of the connecting bracket, and the bottom bracket is located on both sides of the sliding groove.

[0013] The protruding bottom bracket is used to place the connecting bracket to avoid interference between the bottom bolts and the desktop or work surface, which makes sliding inconvenient. The bottom bracket is located on both sides of the sliding groove to avoid interference.

[0014] Optionally, handshake holes are provided at both ends of the connecting bracket.

[0015] By providing the handshake hole, the operator can more easily grasp the connecting bracket, thereby achieving rapid movement and improving work efficiency.

[0016] Optionally, the side surface of the end plate bracket 2 is adaptively fitted with the edge of the handshake hole.

[0017] Compared with the situation where the edges do not fit together, this can extend the sliding distance of the end plate bracket 2 and adapt to the size and length of different battery modules.

[0018] Optionally, both ends of the battery module are provided with end plate fastening blocks, which are bundled with steel strips. The heights of end plate bracket one and end plate bracket two are both matched with the end plate fastening blocks, and the end plate fastening blocks are located in the middle of the battery module.

[0019] The end plate fastening block can be placed directly on the end plate bracket 1 and the end plate bracket 2 with good height adaptation, saving operation time, and making the end plate fastening block and the steel belt located in the middle of the battery module to avoid imbalance and improve the stability of the battery module.

[0020] Optionally, the end plate fastening block is a hollow structure.

[0021] By removing unnecessary material, the weight of the end plate fastening block can be significantly reduced, which is especially important for equipment that needs to be moved or carried.

[0022] Optionally, a hollow hole is provided on the connecting bracket.

[0023] The hollow holes can significantly reduce the weight of the connecting bracket, which is especially important for equipment that needs to be moved or transported.

[0024] Beneficial effects

[0025] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0026] The technical solution provided by the utility model forms a limit for the battery module by setting a stacking bracket, an end plate bracket 1 and an end plate bracket 2. The end plate bracket 2 can slide to flexibly pack and organize the battery modules, thereby improving the operating efficiency and the stability of the battery modules.

[0033] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

[0034] Example

[0035] Combined with attachment Figure 1-5 A battery module packaging steel strap stacking tool includes a connecting bracket 1, which is a rectangular strip. Connecting bracket 1 is provided with a stacking bracket 11, which is also a rectangular strip and shorter than connecting bracket 1. A battery module 10 includes an end plate fastening block 9, an epoxy board, battery cells, and a thermal pad between the battery cells.

[0036] End plate bracket 1 (6) and end plate bracket 2 (2) are provided at both ends of stacking bracket 11. End plate bracket 1 (6) and end plate bracket 2 (2) are taller than stacking bracket 11. End plate bracket 2 (2) can be fixedly slidably connected to connecting bracket 1, sliding toward or away from stacking bracket 11. End plate bracket 1 (6) is bolted to one end of connecting bracket 1. Pre-placement slots 12 for accommodating steel strips are provided between stacking bracket 11, end plate bracket 1 (6), and end plate bracket 2 (2). Side plate brackets 5 are fixed to the sides of connecting bracket 1, and are connected to connecting bracket 1 via side plate bottom brackets 4. End plate bracket 1 (6) is used for fixing and determining the height relative to the battery cells. Stacking bracket 11, side plate bottom bracket 4, side plate bracket 5, bottom bracket 3, and end plate bracket 1 (6) are all fixed to connecting bracket 1 via screws.

[0037] The side panel bracket 5 is made of non-metallic material and is inserted into the bottom bracket 3 of the side panel using a pin. It is used to align the battery cells when stacking modules and is located on the side of the human body during transportation to prevent the module from moving on the tooling during tooling transportation. After the tooling is placed on the extrusion tooling, the side panel bracket 5 is removed to facilitate the installation of the steel belt.

[0038] The bottom of the end plate bracket 2 is provided with a threaded hole that cooperates with a bolt to fix it. The connecting bracket 1 is provided with a sliding groove 102. The bolt cooperates with the sliding groove 102 and is fixed after the bolt is tightened. A protruding bottom bracket 3 is fixed to the bottom of the connecting bracket 1. The bottom bracket 3 is located on both sides of the sliding groove 102. The length of the bottom bracket 3 is slightly shorter than the connecting bracket 1, but it cannot be too short. It needs to play the role of supporting the entire connecting bracket 1. The end plate bracket 2 2 is a movable part. The end plate fastening block 9 is close to the module during assembly to ensure that the end plate fastening block 9 is at the correct height relative to the battery cell. After the end plate fastening block 9 is installed, it is removed.

[0039] The two ends of the connecting bracket 1 are provided with handshake holes 101. The side surfaces of the end plate bracket 2 fit in with the edges of the handshake holes 101. The edges of the handshake holes 101 are provided with rounded corners to improve the grip comfort.

[0040] Both ends of the battery module 10 are equipped with end plate fastening blocks 9, which are used to bind the battery module 10. The heights of end plate bracket 1 6 and end plate bracket 2 2 are aligned with these blocks, which are located in the center of the battery module 10. These blocks are hollow and square, with rounded corners that mate with the steel straps. Two steel straps are provided: Steel Strap 1 7 and Steel Strap 2 8. This creates a symmetrical structure, further enhancing the stability of the package.

[0041] The connecting bracket 1 is provided with a hollow hole 103 located at the bottom of the stacking bracket 11 .

[0042] Working principle:

[0043] After assembling all parts of the tooling, place the end plate bracket 2 on the outermost side to prevent interference with assembly. Slide the steel strip 1 7 onto the stacking bracket 11. The module's end plate fastening blocks 9, epoxy board cells, and thermal pads are stacked sequentially. Once assembly is complete, place the end plate bracket 2 close to the module, align the bottom of the final end plate fastening block 9, and stack it onto the module. This completes the module stacking process. Transfer the tooling and module to the extrusion tooling, remove the side brackets, and after extruding to the appropriate position, install the steel strip from the module slot onto the module. Release the extrusion tooling to complete module assembly. The extrusion tooling is a similar compression tooling to an external robot arm.

[0044] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the inventive purpose of the present invention, designs a structure and embodiment similar to the technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
