Abstract

The invention relates to a laser welding device and method based on laser cleaning pretreatment.The device comprises a conveying belt, a clamping and adsorption device, a laser cleaning device and a laser welding device.A laser cleaning work region is arranged on the front portion of the conveying belt, and a laser welding work region is arranged on the rear portion of the conveying belt.The laser cleaning device is arranged in the laser cleaning work region, and the laser welding device is arranged in the laser welding work region.The clamping and adsorption device used for fixing butt joint machining welding openings of two to-be-welded metal sheets is adsorbed on the conveying belt.Due to the fact that the laser cleaning process is used for conducting rust and paint removal treatment on the surfaces of to-be-welded materials before welding, and the quality of welded joint seams can be improved.The laser cleaning device and the laser welding device are integrated, the laser cleaning work region and the laser welding work region can be accurately positioned through the machine vision image acquisition and positioning technology, automatic cleaning and welding are achieved, the working efficiency and stability of the device are improved, and therefore welding efficiency is improved.

Description

technical field [0001] The invention relates to laser welding, in particular to a laser welding device and method using a laser cleaning pretreatment process. Background technique [0002] With the rapid development of the industrial laser industry, the market has higher and higher requirements for laser processing technology. As a relatively novel joining process, laser welding technology has great potential for innovation. The application prospect of laser welding technology in the field of industrial processing is becoming more and more extensive, and the technology is becoming more and more mature. It has become an advanced manufacturing method integrating multiple disciplines and technologies such as optics, mechanics, electricity, computers and materials. Since laser welding conforms to the technical development direction of high quality, low consumption, high efficiency, cleanness, narrow heat-affected zone, small joint deformation, and flexible operation, the 21st ce...
