DMK 3D Seam Tracking Sensor for Robotic Welder

Principle of Operation

The Seam Tracking Sensor utilizes advanced laser triangulation technology. The laser is diffused into a line laser via a cylindrical objective lens and projected onto the surface of the target object, forming diffuse reflection. The reflected light is then captured by a CMOS camera. By analyzing changes in position and shape of the reflected light, the sensor accurately measures displacement and surface shape.

Product Description

Our Seam Tracking System uses cutting-edge sensor technology and sophisticated algorithms to enable high-precision, real-time tracking of the welding seam. This ensures that welding deviations are kept to an extremely minimal range, significantly improving the accuracy and consistency of welds.

With the ability to detect and track multiple types of seams, including:

• Semi-V groove welds

• Butt welds

• Overlap angle welds

• Flanged overlap welds

• V groove welds

• Lap welds

• Double flanged welds

• External corner welds

Our system is designed to handle a wide range of measurement scenarios, from 0.011mm resolution to 1.758mm and a measuring range of 12mm to 1100mm, providing the precision and flexibility required by most industrial applications.
