Automatic laser welding device

Abstract

The invention relates to an automatic laser welding device which comprises a welding station and a detection station which are arranged on a workbench. The welding station comprises a rotary chuck arranged on the workbench, a fixing device, and a welding head fixing device used for fixing a welding head; the rotary chuck comprises a rotary base; three pneumatic welding clamping jaws are arranged at the upper end of the rotary base in a 120-degree mode, and are connected with high-pressure gas through gas pipes; a servo motor I is installed below the rotary base; the detection station comprisesa rotary disc and a visual detection device arranged on the periphery of the rotary disc; more than four through holes are uniformly distributed in the rotary disc along the circumferential direction; the axis of the bottom of the rotary disc is connected with a servo motor II; the visual detection device comprises a vertical fixing plate and a camera connected to the upper end of the fixing plate and used for visual detection; and the camera is located over the through holes in the rotary disc. The automatic laser welding device further comprises a mechanical arm arranged on the workbench and used for transferring welded products, so that the intensity of operators and the production cost are reduced, and the quality of products to be welded is improved.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a laser automatic welding device. Background technique [0002] Automotive airbags are composed of sensors, gas generators and airbags. They are a safety system that provides protection for passengers. The airbag inflates and expands in a short time. In the production process of the generator, various gunpowder needs to be packed in the upper and lower metal shells, and then the upper and lower shells are welded into one body; the welding quality and strength directly determine whether the airbag can be deployed safely and quickly. [0003] In the traditional welding method, laser welding is often used, manual welding and the quality of the welding surface are checked by visual inspection. The welding depth needs to be selected and obtained after the destructive cutting of the welding product; the production efficiency of the traditional welding method is low, and the manu...

[0003] In the traditional welding method, laser welding is often used, manual welding and the quality of the welding surface are checked by visual inspection. The welding depth needs to be selected and obtained after the destructive cutting of the welding product; the production efficiency of the traditional welding method is low, and the manual inspection of the welding quality cannot To ensure accuracy, it is easy to cause cost waste or flow out of unqualified products to be welded
