Automatic laser welding system

Abstract

The invention provides an automatic laser welding system. The automatic laser welding system comprises a machine table, a laser welding head drive device, a tool clamp, a 3D detecting device, a smoke-extraction and dust-removal device, a mechanical hand loading and unloading device, a material rotary disc device, a wiping device, a 2D detecting device, a sorting device, a workpiece conveyor line and a code scanning device, wherein the welding head drive device drives the laser welding head to move or deflect; the tool clamp realizes clamping and rotating of the workpiece; the 3D detecting device detects a three-dimensional shape of a welding seam; the mechanical hand loading and unloading device is used for grabbing the workpiece to realize loading and unloading; the material rotary disc device is used for sequentially rotating the welded workpiece to a wiping station, a detecting station and an unloading station; the 2D detecting device is used for detecting a quality state of the surface of the welding seam; and the code scanning device is used for reading bar codes or two-dimensional codes which are matched with welding parameters to store. The automatic laser welding system hasthe characteristics of being capable of performing circumferential welding on the welding seam workpiece, automatically loading and unloading, welding, 3D/2D detecting, sorting and the like, does notneed manual operation, is high in efficiency, and enables welding parameters to be corresponding to bar codes.

Description

technical field [0001] The invention is used for the automatic welding of workpieces of circular weld seams, and is especially suitable for an automatic laser welding system for the outer casing of an automobile safety air bag generator. Background technique [0002] With the progress and development of science and technology, laser has been used as a tool in various industries. Due to the high brightness and high intensity of the laser, and the size of the laser spot can be focused to the order of microns by the focusing lens, the focusing energy of the laser is very high, so it is very suitable for workpiece welding with some precision requirements. In addition, as people have higher and higher requirements for automated production and workpiece traceability, the combination of laser, automation and workpiece traceability will be an important direction for the future development of the automation industry. [0003] At present, the degree of automation of laser welding equ...

Problems solved by technology

[0003] At present, the degree of automation of laser welding equipment on the market is not very high. Often, laser welding equipment is used as a stand-alone machine, which is out of touch with other processes such as inspection, wiping, and sorting, resulting in low efficiency, cumbersome manual operations, and the workpiece cannot be traced after welding.
