Project Background：

The customer needs to perform laser marking on formed steel bars. The workpieces are processed at high temperatures, including red-hot parts, and the product range covers multiple sizes and specifications.

3D Vision Solution：

The customer uses an ALSONTECH line laser 3D camera to position the end faces of round steel bars, enabling automated laser marking under high-temperature conditions.

- The conveyor feeding method and rod-shaped workpiece structure create uncertain incoming poses, and the 3D vision system provides accurate positioning for the marking robot. - The laser 3D camera adapts well to red-hot, glowing workpieces and reflective metal end faces, enabling stable imaging and reliable point cloud acquisition. - Fast center-point or centroid extraction enables quick positioning of the marking location without modeling, while supporting flexible switching between multiple part types. - Routine maintenance only, system service life ≥5 years.

Customer Benefits：

- Replaces manual operation and mechanical structures for position compensation, providing high accuracy, reliability, and efficiency. - The environment is harsh and workpieces may remain red-hot, so non-contact positioning offers a safer and more reliable solution.
