Welding device for automobile safety air bag generator

Abstract

The invention belongs to the field of laser welding and particularly relates to a welding device of an automobile safety air bag generator. The welding device comprises a rack, a welding head arrangedon the rack, a multi-station turntable arranged under the welding head, multiple turning discs rotatably arranged on the multi-station turntable and generator jigs arranged on the turning discs and rotating with the turning discs. Generator bodies on the generator jigs are driven to rotate together through the turning discs, the generator can be welded through cooperation with the welding head onthe rack, and during generator welding, the feeding and discharging processes of the generator are simultaneously performed by adding the multi-station turntable for adjusting the positions of the turning discs. The welding device is high in welding speed, small in workpiece deformation, low in maintenance cost, capable of meeting the high-strength welding requirements and high in welding efficiency.

Description

technical field [0001] The invention belongs to the field of laser welding, and in particular relates to a welding device for an automobile safety airbag generator. Background technique [0002] The airbag system is a passive safety protection system for automobiles. It is used in conjunction with seat belts to provide effective collision protection for occupants. In a car collision, car airbags can reduce the head injury rate by 25% and the face injury rate by about 80%. With the continuous development of the manufacturing level of the automobile industry, the penetration rate of the airbag system in the passenger car market is getting higher and higher, and the market capacity is increasing, and the airbag generator is an important part of the entire airbag system. The weld quality of the generator has a significant impact on the performance of the airbag system. [0003] Using traditional welding methods to weld airbag parts is prone to the problem of partial melting of...
