Spot welding device and welding method

Abstract

The invention discloses a spot welding device. The spot welding device comprises a welding main chassis, and a refrigerator arranged on one side of the welding main chassis; a welding table is arranged on the other side of the welding main chassis, and includes a frame; a first slide rail and a second slide rail, perpendicular to each other, are horizontally arranged at the upper part of the frame; the second slide rail is arranged at the upper part of the first slide rail, and is provided with a support table for placing workpieces to be welded; multiple welding points are arranged on the support table in a matrix form; the frame is provided with a laser welding machine on the back side of the first slide rail; and the laser welding machine is connected with the welding main chassis. The multiple welding points are arranged on the support table in a matrix form; a controller uses the welding points for programming; the workpieces to be welded are welded by a spot welding mode; and the welding strength and the laser beam strength needed by each point, required to be welded of the workpieces to be welded, can be specifically set according to the thickness of each point to achieve more precise and delicate welding, so that the generation of defectives is reduced.

Description

technical field [0001] The invention relates to the field of welding, in particular to a spot welding device and a welding method for laser welding. Background technique [0002] At present, electronic products have become an indispensable part of our lives, and their importance cannot be overstated. Electronic components are the basis of electronic products. Achieving miniaturization, thinning, and lightweight design requires more precise welding of electronic components. [0003] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlli...
