Automotive and supplier industry

In the meantime a vast number of structural components in the automotive industry are made of tubes, e.g. engine cradles, seat frames, roll bars, head rests, exhaust systems.

Weld seam detection and positioning for further processing in tube bending machinery is therefore one of the most common applications in automotive frame production.

The necessary repeatable geometries for further processing require repeatable positioning of the weld seam.

Spring lathe coiler

Weld Seam Detection in steel strips of a coil winding machine for automotive safety belt retractors.

This application demonstrates the detection of overlapping weld seams of spring steel strips.

The weld seams are not allowed to enter into the spiral winding machine.

The spring coil winding machine for belt retractor operates in a start/stop mode to ensure a fixed length for each spring steel strip.

In this process it can happen that the weld seam stops inside the encircling coil. Even in this case the detection is successful because the weld seam detector detects the weld seam both in movement and also at standstill.

Manufacturing of gas tubes

Continuous soldering line of automotive gas tubing.

The encircling coil sensors detect the tube connections which occur in these 12 parallel lines arbitrarily.

Manufacturing of catalytic converters

Weld Seam Detection during the processing of tube ends for automotive catalytic converters.

A special feature of this application is the vertical position of the catalytic converter tubing and the horizontal movement of the sensor NS9S.

Automated production cell

The tailor-made, automated production cell shown above includes the SND40 Weld Seam Detection System in a combination with a forming and bending machine.
The detection and positioning of the weld seam of the tube is done first before the bending process.
Subsequently, the parts are picked up by a robot to be transferred to the bending and forming process.

Tube loader and tube bending machine

Tube bending line consisting of a tube loader with weld seam detection and positioning, a robot loader and a separate tube bending machine.

The tubes are processed in a hydroforming press to rear axles.

The exact position of the weld is required to ensure the stability of the rear axles.
