Description

Technical Field

[0001] The utility model relates to the technical field of energy storage battery manufacturing, in particular to a welding protective tool for a CCS component of an energy storage battery module. Background Art

[0002] With the rapid development of the energy storage industry, quality and safety control during the production of battery modules, core components of energy storage systems, are receiving increasing attention. The CCS (Cells Contact System) assembly, consisting of an FPC (flexible printed circuit board), series-connected aluminum busbars, and a plastic casing, is a key component connecting individual battery cells to external electrical components. Laser welding is typically used to connect the aluminum busbars to the battery terminals.

[0003] However, during the automated welding process, the thermal effects generated by high-temperature welding may cause deformation and damage to the flexible FPC and plastic shell, or even cause a short circuit. In addition, due to factors such as the difference in aluminum busbar material, laser stability, dust removal wind speed, and shielding gas flow rate, welding slag splashing is inevitable during the welding process. If protection is not in place, it will cause irreparable damage to adjacent FPC internal circuits, temperature sensors and other precision electronic components, resulting in abnormal voltage and temperature acquisition. If welding slag metal foreign matter splashes into the large surface gap of the battery cell and punctures the blue film of the battery cell, it will cause insulation failure, circuit short circuit and other problems, seriously affecting the safety performance and overall durability of the battery. However, existing welding tooling cannot completely and effectively control the metal welding slag splashing onto the FPC surface and the inside of the battery module, posing a safety hazard to the battery.

[0025] The following diagrams provide a more detailed description of the welding protective tooling for the energy storage battery module (CCS) assembly of the present invention, illustrating preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving its beneficial effects. Therefore, the following description should be understood as a general guideline for those skilled in the art and not as a limitation of the present invention.

[0026] For the sake of clarity, not all features of actual embodiments are described. In the following description, well-known functions and structures are not described in detail because they would clutter the present invention with unnecessary detail. It should be understood that in the development of any actual embodiment, numerous implementation details must be made to achieve the developer's specific goals, such as adapting from one embodiment to another to accommodate system or business constraints. Furthermore, it should be understood that such development work may be complex and time-consuming, but is nevertheless a routine undertaking for those skilled in the art.

[0027] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in very simplified form and are not in exact proportions, and are only used for the purpose of conveniently and clearly assisting in illustrating the embodiments of the present invention.

[0028] As mentioned in the background, existing welding protection tooling cannot fully and effectively prevent metal welding slag from splashing onto the FPC surface and inside the battery module, posing a potential safety hazard. In light of this, this utility model proposes a welding protection tooling for CCS components of energy storage battery modules. This tooling utilizes a multi-layered protection structure constructed from composite materials and features perforations in the tooling to precisely cover non-welding areas, effectively protecting the internal battery components.

[0029] See also Figure 1 、 Figure 2 and Figure 3 The utility model provides a welding protective tool for a CCS assembly of an energy storage battery module, comprising a tool plate 1 and a fixing pin structure 2 , wherein the fixing pin structure 2 is arranged at the bottom of the tool plate 1 .

[0030] Specifically, the tooling plate 1 and the fixing pin structure 2 are integrally formed and can be directly mounted on the battery module 3 without secondary assembly. A plurality of welding openings 11 are provided on the tooling plate 1.

[0031] In this embodiment, the tooling panel 1 is a double-layer composite structure, including an inner layer material and an outer layer material, wherein the outer layer material encapsulates the inner layer material. The inner layer material of the tooling panel 1 includes one or more of engineering plastics, resins, nylon, PC, and ABS. The outer layer material of the tooling panel 1 is a heat-resistant ceramic coating. Because the inner layer material is made of lightweight material and the outer layer material is made of heat-resistant material, the tooling panel 1 can be ensured to be lightweight and easy to handle. At the same time, it can effectively isolate the welding heat, reduce the thermal impact on the FPC, and prevent the internal components of the battery module from being damaged by welding slag during the welding process.

[0032] After welding is completed, an explosion-proof vacuum cleaner can be used to clean the surface of the tooling plate 1. After cleaning, the tooling plate 1 can be returned to the process before welding for use, thereby achieving recycling.

[0033] In this example, see Figure 4 The tooling plate 1 is installed above the battery module 3. Two fixing pin structures 2 are provided at the bottom of the tooling plate 1, one on each side of the tooling plate 1. Module end plates 4 are installed on both sides of the battery module 3. The module end plates 4 are provided with bolt holes 41 that match the fixing pin structures 2. The fixing pin structures 2 are fixed above the battery module 3 by being inserted into the bolt holes 41.

[0034] In this example, see Figure 2 and Figure 5 The tooling panel 1 is provided with a plurality of welding openings 11. The shape, size, and location of these welding openings 11 match the welding area 6 of the battery module 3, achieving precise alignment. The welding area 6 is located just below the gap between the non-welding area 7 of the tooling panel 1 and the frame of the tooling panel 1. The non-welding area 7 can fully cover the non-welding area of ​​the battery module 3.

[0035] In this embodiment, the battery module 3 includes a CSS component 5 , and the CSS component 5 is installed on the top of the battery module 3 .

[0036] Specifically, the CSS component 5 includes an aluminum bar 51 and an FPC 52. The tooling panel 1 covers the FPC 51. The aluminum bar 51 is on the welding area 6 on the FPC 52. After the tooling panel 1 is fixed to the battery module 3, the aluminum bar 51 in the welding area 6 is laser welded from the gap between the non-welding area 7 and the frame of the tooling panel 1.

[0037] In summary, the present invention facilitates the welding of battery modules by adopting a tooling plate with multiple welding openings. At the same time, the tooling plate adopts a double-layer composite structure, which makes the tooling plate light and easy to handle, and effectively isolates the welding heat, reduces the heat effect on the FPC, and can prevent the internal components of the battery module from being damaged by welding slag during the welding process. In addition, the present invention adopts a fixed pin structure to achieve the fixation of the tooling plate and the battery module, ensuring that the tooling will not loosen during the welding process. Furthermore, the tooling plate used in the present invention is provided with multiple welding openings, the shape, size and position of which match the welding area of ​​the battery module, and the remaining part fully covers the non-welding area, which can well prevent the internal components of the battery module from being damaged by welding slag during the welding process.

[0038] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, makes any equivalent substitution, modification, or other variation to the technical solution and technical content disclosed herein shall be deemed to fall within the scope of the present invention and remain within the scope of protection of the present invention.
