Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, and more particularly to a laser head bracket for laser positioning. Background Art

[0002] During the welding process, seam tracking technology is an important part of intelligent welding technology. There are many types of seam tracking technologies, such as tracking using video technology, tracking using laser ranging technology, or tracking using mechanical parts.

[0003] Currently, the most commonly used laser monocular weld seam tracker both domestically and internationally is the one that utilizes laser positioning and triangulation for tracking. Monocular laser weld seam trackers are simple and easy to use, making them suitable for welding environments with smooth, minimal weld bead changes. However, their use is limited in welding environments with significant weld changes and complex structures.

[0004] For example, when welding or cutting, the tip of the welding gun or spray gun needs to be close to the workpiece, but the position of the laser on the tip is fixed, which can easily cause interference between the workpiece and the laser positioning tracking device. The shape of the workpiece sometimes blocks the laser, and the tip of the gun cannot reach the predetermined position of the workpiece, affecting the processing quality and efficiency of the workpiece.
