Lithium battery laser welding equipment for new energy automobile

Abstract

The invention discloses lithium battery laser welding equipment for a new energy automobile, and belongs to the technical field of welding. The problems that a pressing plate of an existing device cannot adjust the inclination angle of a lithium battery, and the welding difficulty of the lithium battery is increased are solved. The lithium battery laser welding equipment for the new energy automobile is characterized in that the equipment comprises a base, two positioning cavities are symmetrically formed in the base, lifting assemblies are arranged in the positioning cavities, driving assemblies are connected to the lower portions of the lifting assemblies, a lifting table is connected to the upper portions of the lifting assemblies, and a workbench is arranged on the lifting table; and an angle adjusting assembly used for adjusting the inclination angle of the lithium battery is arranged between the workbench and the lifting table. According to the embodiment of the invention, the angle adjusting assembly is arranged, when the inclination angle of the workbench needs to be adjusted, a second hydraulic cylinder is started, and the second hydraulic cylinder drives a hinge block tomove, so that the hinge block drives the workbench to rotate, and the purpose of laser welding of different positions of the lithium battery is achieved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a lithium battery laser welding device for new energy vehicles. Background technique [0002] 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. The welding process is of heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, etc. parameters to melt the workpiece to form a specific molten pool. [0003] Chinese patent CN204339124U discloses a rotary laser welding equipment for lithium batteries, which includes a frame and a circular frame set on the frame, a circular turntable is arranged on the circular frame, and a c...
