Weld joint real-time tracking device based on laser vision

Abstract

The invention provides a real-time welding seam tracking device based on laser vision. The real-time welding seam tracking device comprises a welding equipment body, and a bearing structure is arranged on the side face of the welding equipment body; a moving structure is arranged on the top side of the bearing structure; the other side of the bearing structure is slidably connected with a clamping structure; a positioning structure is connected between the clamping structure and the bearing structure; a fixing structure is arranged on the top side of the clamping structure; the bottom side of the welding equipment body is fixedly connected with a cleaning structure; a to-be-welded steel plate can be horizontally placed through the bearing structure, the welding accuracy is guaranteed, the steel plate with the large area can be conveniently moved through the moving structure, the welding sides of the two fixed steel plates can be kept parallel through the clamping structure, the width of a welding seam can be adjusted through the fixing structure, and the welding efficiency is improved. The welding seam between the steel plates can be accurately adjusted through the positioning structure, and dust at the welding position can be cleaned through the cleaning structure.

Description

technical field [0001] The invention belongs to the technical field of real-time tracking of welding seams, in particular to a real-time tracking device for welding seams based on laser vision. Background technique [0002] The welding seam tracking technology based on laser vision is to obtain the 3D position of the welding seam between the welding plates through the capture of laser and camera, so that the welding position can be adjusted independently through the computer, so as to realize intelligent unmanned welding and ensure the accuracy of welding To improve the efficiency of welding process. [0003] However, when using laser vision-based real-time seam tracking devices to weld plates, the steel plates to be welded are usually placed together directly. If the steel plates have a large area, it is difficult to ensure that the welding surfaces between the steel plates are relatively parallel. It may cause a decline in welding quality. At the same time, if the welded ...

[0003] However, when using laser vision-based real-time seam tracking devices to weld plates, the steel plates to be welded are usually placed together directly. If the steel plates have a large area, it is difficult to ensure that the welding surfaces between the steel plates are relatively parallel. It may cause a decline in welding quality. At the same time, if the welded steel plate is a non-rectangular special-shaped structure, it is inconvenient to adjust the position of the steel plate during linear welding. During the welding process, impurities on the steel plate will also affect the equipment. For real-time sampling and tracking of weld seams
