[0002] With the continuous pursuit of lightweight in the intelligent manufacturing industry, aluminum alloy has become the preferred material in many high-end manufacturing fields due to its low density, high strength and good corrosion resistance. Especially in the field of new energy vehicles, aluminum alloy is widely used in the manufacture of battery shells to reduce the weight of the whole vehicle and improve energy efficiency.

[0003] As the structure of aluminum alloy battery shells is usually complex, multiple aluminum alloy parts need to be precisely spliced ​​together through welding process. This process is crucial to ensure the structural integrity and sealing of the battery shell.

[0004] In order to improve production efficiency, multiple industrial robots are often required to perform welding operations synchronously on automated production lines. However, due to the particularity of aluminum alloy materials and possible problems such as unreasonable grounding or electromagnetic interference during welding, the stability and quality control of the welding process face great challenges.

[0005] Traditional welding fixtures and grounding methods may not meet the specific requirements of aluminum alloy welding, especially in the scenario of multi-robot synchronous welding. These problems may lead to unstable welding quality and affect the consistency and reliability of the product.

[0006] In order to solve the above problems, the intelligent manufacturing industry urgently needs a new type of welding fixture, which can provide stable and reliable grounding and improve welding quality and production efficiency. Utility Model Content

[0007] The purpose of the utility model is to provide a tooling fixture for an automated welding production line in order to overcome the defects of the above-mentioned prior art. The fixture has a grid structure formed by array-type grounding blocks and electrical connections, which can be efficiently connected to multiple welding robots to improve the stability and quality of aluminum alloy material welding and meet the dual needs of the intelligent manufacturing industry for lightweight and high efficiency.

[0008] The purpose of the utility model can be achieved through the following technical solutions:

[0010] Furthermore, the grounding blocks are evenly distributed on the fixture body.

[0011] Furthermore, adjacent grounding blocks are connected via lines.

[0012] Furthermore, the plurality of ground blocks and the circuits form a grid structure.

[0013] Furthermore, the ground block is made of metal conductor material.

[0014] Furthermore, the fixture body is used to fix the workpiece to be welded.

[0015] Furthermore, the workpiece to be welded is fixed to the upper surface of the fixture body.

[0016] Furthermore, the plurality of grounding blocks are all fixed to the lower surface or the upper surface of the fixture body.

[0017] Furthermore, the six grounding blocks are connected with grounding cables, and the six grounding cables are respectively connected to six welding devices.

[0018] Furthermore, the welding equipment is a six-axis welding robot.

[0019] Compared with the prior art, the utility model has the following technical advantages:

[0020] 1) Improve welding efficiency and quality: The array-type grounding block layout on the fixture body achieves comprehensive grounding of the welding workpiece, which helps to evenly distribute and stabilize the current flow, thereby significantly improving welding efficiency and welding quality. The use of metal conductor materials ensures good electrical conductivity and further enhances welding stability.

[0021] 2) Optimized grounding structure design: The grid structure formed by connecting adjacent grounding blocks through lines not only optimizes the flow path of the current, but also reduces the resistance and voltage fluctuation by reducing the cable length, further improving the stability of welding quality. At the same time, this design also simplifies the cable layout and facilitates maintenance and operation.

[0022] 3) Realize multi-robot synchronous welding: The connection between 6 grounding blocks and 6 six-axis welding robots meets the grounding requirements of multi-robot synchronous welding, allowing welding operations to be performed at multiple locations at the same time, greatly improving production efficiency.

[0023] 4) Enhance the stability of the welding process: The interconnection principle of each grounding electrode ensures the shortest distance between the parts on the tooling and each welding machine, thereby minimizing resistance, reducing voltage fluctuations, and ensuring the stability of the current during welding, which is crucial to ensuring welding quality.

[0024] 5) Improve the flexibility and safety of operation: The design of the fixture body allows the workpiece to be welded to be fixed on its upper surface, ensuring the accurate and stable position of the workpiece during welding, while also improving the safety of operation.
