Embodiment 1

[0018] see figure 1 , The welding device for ultra-thin metal sheets includes two heat sinks 1, 2 of block structure, and the two heat sinks 1, 2 superimpose and clamp two metal sheets 3, 4 to be welded. figure 1 (Including other drawings) The thickness of the metal sheets is intentionally enlarged, but actually the thickness of the metal sheets 3 and 4 is only 0.01mm-0.15mm. The radiators 1, 2 are in close contact with the metal sheets 3, 4. The edges to be welded of the metal sheets 3 and 4 are flush and protrude from the surface of the radiator 1 and 2, and the protruding distance H is not more than 2 mm.

[0019] The welding device also includes a laser 5 for welding and welding the metal sheets 3 and 4 . The laser 5 is aimed at the edges of the two metal sheets 3, 4 to be welded. During welding, the edges of the two metal sheets 3 and 4 are welded and welded with the laser 5 so that the two metal sheets 3 and 4 are welded together. Since radiators 1 and 2 can quickly ...

Embodiment 2

[0023] see figure 2 and image 3 , The radiators 6 and 7 of this embodiment are rollers, and the two rollers sandwich the two metal sheets 3 and 4 to be welded. The distance H of the welded edges of the metal sheets 3 and 4 protruding from the end face of the roller does not exceed 2 mm. The radiators 6 and 7 of the two roller structures can drive the metal sheets 3 and 4 along the figure 1 The direction perpendicular to the drawing moves, so that the metal sheets 3, 4 and the laser 5 move relative to each other. Other structures and welding methods of this embodiment can refer to Embodiment 1.

Embodiment 3

[0025] see Figure 4 , In this embodiment, cooling liquid channels 8 are provided in the cooling bodies 1 and 2 to further increase the heat dissipation speed of the cooling bodies 1 and 2 . Other structural features and welding methods of this embodiment can refer to Embodiment 1.

Abstract

The invention discloses a welding method and a welding device for ultra-thin metal sheets. The method comprises the steps that a radiator body of the welding device is used to clamp the metal sheets to be welded in an overlapping manner, so that the radiator body and the metal sheets are tightly contacted; to-be-welded edges of the metal sheets are flushed, and the flushed edges of the metal sheets bulge or are lower than the surface of the radiator body, and a distance for bulging or being lower than the surface of the radiator body is less than 2 mm; and a laser of the welding device is aligned to the to-be-welded edges of the metal sheets to perform burn-in welding. According to the welding method and the welding device for the ultra-thin metal sheets, the blank of an ultra-thin metal sheet welding technology is filled, the ultra-thin metal sheets with the thicknesses in a range from 0.01 mm to 0.15 mm are welded together, and the metal sheets are prevented from being burned out simultaneously.

Description

technical field [0001] The invention relates to the welding of metal sheets, in particular to the welding of ultra-thin metal sheets with a thickness of 0.01 mm to 0.15 mm. Background technique [0002] At present, there is no technology for welding ultra-thin metal sheets with a thickness of 0.01 mm to 0.15 mm without burning the metal sheets, which cannot meet the production needs. Contents of the invention [0003] The object of the present invention is to provide a method for welding ultra-thin metal sheets, which can weld ultra-thin metal sheets with a thickness of 0.01 mm to 0.15 mm together without burning the metal sheets. [0004] Another object of the present invention is to provide a welding device for ultra-thin metal sheets to realize the above method. [0005] The method of the present invention is realized in the following way: in the ultra-thin metal sheet welding method, the metal sheets to be welded are overlapped and clamped by the radiator, so that the...
