Robotized Structured Light Scanning System Measures Volvo Cars Trim Parts

The Adler Pelzer Group works together with ARGON to tune pre-production of automotive trim parts using structured light scanning. The test parts are placed on 3D scanning optimized fixtures, designed and produced by ARGON. Robotized 3D scanning, performed in-house at ARGON, allows Adler Pelzer to increase measuring productivity and receive timely accurate reports. ARGON and Adler Pelzer engineering specialists analyse and evaluate the results as a team in order to propose how and where to improve the components. With the acquired geometrical insights,Adler Pelzer is able to meet tighter quality requirements and speed up the iterative pre-production process.

The Adler Pelzer Group is a system supplier and development partner for all major companies in the automotive industry for automotive NVH and soft trim components. The Adler Pelzer Group realizes a turnover of more than EUR 1,150 million with 10.000 employees at 68 locations throughout the world. The Adler Pelzer Group is an experienced acoustic integrator, which considers the quality of its trim components a key success factor.

For geometry inspection, the company counts on flexible, on-demand measuring services executed by ARGON in Belgium.

“ARGON is no stranger to us,” says NelsonDias, Research and Development department of Adler Pelzer. “We are using ARGON’s dedicated scan-optimized fixtures to measure our trim parts.When considering measurement outsourcing, we selected ARGON and its robotized 3D scanning services. We ship batches (containing 300-400 trim assemblies each) over to ARGON, and receive accurate inspection reports already a few days later.”

Before measurement starts off, an operator clamps a new trim part on an ARGON3D scanning fixture. The robotized 3D blue-light scanning solution consists of an ATOS Triple Scan system mounted on a FANUC robot. On average, the robot requires approximately five minutes to scan the entire surface of a single trim part.The graphic measuring reports allow the engineers to evaluate trim part geometry using part-to-CAD comparison charts. They can focus on any trim regions of interest, and analyse underlying measuring data and statistics as desired.

“We value ARGON’s reliable fixtures with innovative clamping, engineered to scan the entire trim surface 30 to 40% faster,” concludes Nelson Dias. “The graphic inspection reports allow us to identify metrology trends and tune manufacturing accordingly. We also take into account GD&T analysis, to keep a close eye on trim tolerancing aspects. As the reports are delivered in Volvo DMIS-format, we can hand over them to our costumer Adler Pelzer so that they can upload the reports directly into Volvo’s manufacturing execution system (MES). By scanning pre-production trim parts, we are able to gain deeper insight, increase quality and move faster to high-volume production.”
