Lithium battery laser welding precise clamp

Abstract

The invention relates to a lithium battery laser welding precise clamp. The lithium battery laser welding precise clamp comprises a housing, the housing is provided with a turntable, a linear motion mechanism, a clamping jaw and a C-shaped member, the turntable is provided with the linear motion mechanism, the liner motion mechanism is provided with the C-shaped member, the clamping jaw is arranged in the C-shaped member, the turntable is internally provided with a rotary shaft to be connected with the clamping jaw and the C-shaped member separately, and the rotary shaft is used for synchronous rotation. Aiming at laser precise welding, through the welding clamping jaw which approaches an ideal motion trail, distinguished from a mode of traditional laser welding in which XY motion interpolation is adopted, and through the cooperation of the use of the welding clamping jaw, the position of a welded point is precisely positioned, continuous and automatic welding is achieved, and the welding efficiency is improved. The lithium battery laser welding precise clamp is practical, convenient to use and simple in structure.

Description

technical field [0001] The invention relates to a welding device, in particular to a lithium battery laser welding precision jig. Background technique [0002] With the aggravation of global warming and environmental deterioration, countries all over the world attach great importance to environmental protection, and new environmentally friendly and efficient energy storage equipment has been developed rapidly. Compared with traditional lead-acid batteries that pose a greater threat to environmental pollution, lithium batteries, as rechargeable energy storage components, have developed rapidly in recent years and are widely used in electronic products, automobiles, and communication base stations. Lithium batteries are widely manufactured using aluminum shells as carriers. Laser welding is widely used in the automotive industry for welding aluminum materials. Because aluminum materials have a high absorption efficiency for lasers, aluminum shell lithium batteries are also wid...

Problems solved by technology

[0003] From a structural point of view, if Figure 10 As shown, in the traditional laser welding of circular arcs, XY interpolation motion is used to walk out of the motion trajectory of an approximate circular arc, and the laser is not perpendicular to the weld seam trajectory during welding of circular arcs, which leads to the laser welding when welding arcs and welding straight lines. Inconsistent energy diffusion, weld convex edges or pits in the arc section often appear, and defects such as incomplete penetration and leakage are also prone to occur
