Image processing for cutting and welding applications

Trust in your process with TRUMPF process sensors.

Total confidence with TRUMPF process sensors!

You can avoid defective parts with VisionLine, TRUMPF's image processing solution. Camera-based image processing means you can keep an eye on everything for cutting and welding applications. VisionLine automatically detects the component position, forwards this information to the control, and ensures that the welding seam is always in the right place. With the Basic, Detect and Project options, you can choose between simple monitoring of the workpiece, characteristics recognition or a customer-specific extension. Image processing is available for lasers with optics as an integrator package as well as for the TruLaser Station and TruLaser Cell systems.

Thanks to the intuitive user interface and pre-defined attribute library, it is very easy to integrate VisionLine in the production process. After just a few work steps, the operator can start right away.

Highly integrated solutions from a single source

Enjoy the benefits of having TRUMPF as an entire system supplier – from the laser to the process sensor system and consulting.

Improve process capability

Reduce your component positioning requirements without any loss of quality.

Easy to do by yourself

The attribute library supports the person doing the set-up work as they create their image processing tasks.

Transparent and reliable

You can save image data at any time to guarantee traceability.

Hairpin welding with VisionLine image processing

Hairpin welding with VisionLine image processing

A typical application for VisionLine image processing is
position recognition of hairpins in stators which are used in electric motors.

Welding of electronic components

The image processing system detects the pins that are to be welded, for example in electronic control units, sensors and actuators.

Laser welding of joint connections

Welding of joint connections

Image processing enables you to detect seam points when welding heat exchangers or seat rails and means that these are welded at the right location.

Image processing, VisionLine Basic

VisionLine Basic

A digital camera image with cross-hairs in the laser focus helps with monitoring the workpiece and during teaching. Using the VisionLine Basic in combination with the TRUMPF scanner optics of the PFO series is particularly advantageous. In this case, the offset between the laser light and monitoring light outside of the centre of the scan field is corrected so that the focus position shown in the image corresponds to the actual position of the laser focus.

Detection of characteristics with VisionLine Detect

VisionLine Detect

Edge-detection offers the option of integrating simple characteristics recognition on the workpiece in the production process for position correction. The appropriate distinguishing features (for example, blots, circles, lines or intercept points) can be selected from a template library for many application scenarios.
