Description

Technical Field

[0001] This utility model relates to a welding, pressing, and dust removal fixture for aluminum busbars in power batteries, belonging to the field of power battery manufacturing technology. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the quality of power batteries, as a core component, directly affects the performance and safety of the entire vehicle. Simultaneously, improved production efficiency and reduced material loss enable companies to gain a competitive edge in the market. Laser welding of the aluminum busbar connections in power batteries is a crucial step in the manufacturing process, and the welding quality directly impacts the battery's strength and current carrying capacity. However, traditional aluminum busbar welding fixtures with compression and dust removal suffer from poor dust removal, resulting in spatter, foreign matter, and weld holes. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a dust removal tooling for welding aluminum busbars of power batteries, which can improve dust removal efficiency, reduce spatter during welding of aluminum busbars of power batteries, prevent foreign objects, and improve yield.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model adopts a dust collection pipe connected to the side and a dust collection hood connected to the top.

[0027] The following is a specific embodiment of this utility model with reference to the accompanying drawings, and the structure of this utility model is described in detail. It should be noted that the scope of application of this utility model is not limited to the following embodiment; all similar structures based on this utility model are within the scope of application of this utility model.

[0028] This utility model relates to a welding, pressing, and dust removal fixture for aluminum busbars in power batteries, such as... Figures 1-2 As shown, the tooling includes:

[0029] Tooling body 1, which is a conical pressure head structure, is used for clamping work during welding of aluminum busbars of power batteries;

[0030] like Figures 3-5 As shown, the L-shaped connecting plate 2 is fixedly installed on the upper surface of the tooling body 1 on one side and fixedly installed on the side of the tooling body 1 on the other side.

[0031] Dust collection hood 3 is fixedly connected to the upper end face of the L-shaped connecting plate 2 by bolts. The dust collection hood 3 is used to expand the dust collection range, which can effectively reduce dust dispersion and enhance dust collection efficiency. The dust collection hood 3 is an existing technology device.

[0032] Dust removal pipe 4 is fixedly connected to the side of the L-shaped connecting plate 2 by bolts. Dust removal pipe 4 is used to discharge the fumes generated during welding.

[0033] As a further description of this embodiment, such as Figure 3 and Figure 5 As shown, the upper end face and the side face of the L-shaped connecting plate 2 are respectively provided with a first circular opening 201 and a second circular opening 202.

[0034] As a further description of this embodiment, the tooling body 1 has a hollow structure inside, with openings at both its upper and lower ends. The upper opening of the tooling body 1 is connected to the first circular opening 201.

[0035] As a further description of this embodiment, such as Figure 7 As shown, the lower end of the dust collection hood 3 is provided with a dust collection hood air inlet 301, which is connected to the first circular opening 201.

[0036] As a further description of this embodiment, such as Figure 9 As shown, one end of the dust removal pipe 4 is provided with a dust removal pipe air inlet 401, which is connected to the second circular opening 202.

[0037] The working principle of this utility model is as follows:

[0038] This utility model fixture is installed on an existing welding machine. A laser is located above the fixture to perform laser welding on aluminum bars. Then, the main body of the fixture is pressed under the drive of the gantry shaft. The generated dust is removed by the dust removal pipe 4 driven by the existing dust collector, and the dust removal effect is increased by the dust collection hood 3.

[0039] The dust removal effect is as follows:

[0040] 1. Precisely match the movement trajectory of smoke and dust (utilizing the rising of hot air)

[0041] The fumes generated during welding naturally rise due to the high temperature, spreading upwards from the welding position below. The dust collection hood 3 (without suction) at the top is located precisely in the path of the rising fumes, acting like a "dome" to firmly capture the upward-spreading fumes and guide them to concentrate inside the hood. The dust removal pipe 4 on the side is located below the dust collection hood 3 and to the side of the welding position, precisely aligned with the path of the concentrated rising fumes, smoothly drawing them away, completely conforming to the natural law of rising fumes and reducing airflow resistance.

[0042] 2. Forming a highly efficient negative pressure field with "downward extraction and upward convergence".

[0043] The welding point is located below the dust collection pipe 4. When the dust collection pipe 4 draws in air, it creates a directional negative pressure above the welding point, directly acting on the newly generated rising fumes to prevent their diffusion. At the same time, the dust collection hood 3 above, through its physical structure, blocks and collects the small amount of fumes that are not directly drawn in by the dust collection pipe 4 and continue to rise, preventing them from escaping into a larger space. The two work together to form a dual control system: the dust collection pipe 4 actively draws in the fumes, while the dust collection hood 3 passively blocks them. The dust collection pipe 4 is responsible for drawing away most of the newly generated fumes, while the dust collection hood 3 is responsible for collecting the remaining rising fumes. The negative pressure field covers the entire path of the fumes from generation to diffusion, leaving no blind spots.

[0044] 3. Completely eliminate airflow interference and prevent smoke and dust backflow.

[0045] The dust collection hood 3 is located above the dust removal pipe 4, and the two are not directly connected. The inside of the hood is only a "transition space" for the accumulation of smoke and dust, without any active airflow interference. The dust removal pipe 4 on the side draws air from below, and the airflow direction is "from the welding point → dust removal pipe 4 → pipe", which is completely consistent with the rising direction of the smoke and dust (welding point → dust collection hood 3 → dust removal pipe 4), forming a smooth "rising-accumulating-exhausting" path, completely avoiding the backflow of smoke and dust caused by airflow collision.

[0046] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this invention.
