3D scan system

SCANLAB AG

SCANLAB AG and its subsidiary, Blackbird Robotersysteme GmbH, introduces the intelliWELD II FT to its 3D line of scan systems for robot-assisted welding applications. This new scan system features an integrated zoom axis for variable spot sizes, and flexible seam widths. The compact, industrially-suitable system construction ensures exceptional flexibility and optimal process adjustability, particularly for overlap weld joints widely favored by automakers and other branches. Plus, a modularly-designed, easily-expandable 19-inch rack version of Blackbird's ScanControlUnit is poised for market introduction.

Remote welding - with scan heads mounted on industrial robots - is widespread in auto manufacturing, and offers considerable potential for other branches, too. Here, the scan system manages laser fine-positioning, thus eliminating time-robbing robot repositioning. This has significantly boosted beam utilization rates and manufacturing productivity over the past few years.

The unique solution of a scan head with pre-focus optic is optimized for vision-assisted applications such as fillet welding, with precise seam tracking to an accuracy of 0.1 mm. The new scan system with integrated zoom axis logically extends SCANLAB's product range by adding an application-specific solution package for overlap welding.

The scan head's mechanics fulfill all requirements for industrial manufacturing: a sealed housing with encapsulated optical path and a replaceable protective window with newly-developed protective window monitoring. The system is equipped with latest-generation galvanometer scanners that offer advantages such as minimal position drift. The optical components accommodate disc and fiber lasers with up to 8-kW power. Additionally, integrated internal flash memory stores the scan head's configuration data and correction files. The intelliWELD II FT scan head will be available for ordering in Q4 2015.
