VMT

In the body shop, hundreds of individual parts become a complete vehicle structure within hours – assembled by up to 95% robots. What no one sees: every weld, every position, every adhesive bead is monitored by vision systems.

High cycle times, extreme forces, and minimal tolerances demand reliable inspection directly within the press process to detect deviations at the earliest stage possible.

Vision systems support stable production workflows by ensuring part quality, monitoring critical process parameters, and reducing costly downstream defects throughout the entire production line.

Decades of Dedication

Pioneering progress through decades of experience.

01

Part handling & positioning

Pressed parts are picked by robots and placed precisely into welding fixtures.
Tolerance compensation without mechanical fixturing, flexible for multiple part variants on a single line.
3D position detection of the part, robot correction before placement.
Technology: BestFit / FrameSense

02

Body positioning

Before every joining process, the exact position of the body in space must be known.
Inline measurement at line speed, fully compensates fixture tolerances.
3D detection of body position and orientation based on defined features – holes, edges, surfaces.
Technology: BestFit / OSC

03

Weld seam inspection

Spot welds, laser seams, and MIG/MAG welds must be checked for completeness, geometry, and defects.
100% inline inspection without cycle time loss, quantitative seam geometry evaluation.
Detection of missing weld spots, cracks, porosity, undercuts, and seam interruptions.
Technology: OSC / 3D + BK

04

Adhesive bead inspection

Structural adhesives and sealants are applied automatically and must be reliable for crash performance and sealing.
Real-time feedback loop to the application robot, automatic rework trigger on interruptions, capable of round and triangular bead profiles.
Inspection of position, width, height, and completeness of the bead directly after application.
Technology: SpinTop

05

Inline measurement

At defined measurement stations throughout the body shop, dimensional accuracy of the body-in-white is continuously verified.
Continuous process monitoring across the entire build sequence, early drift detection before tolerances are exceeded.
Contactless 3D measurement of key dimensions, feature positions, and assembly tolerances against CAD reference.
Technology: 3DLE / OSC

06

Racking & deracking

Bodies and subassemblies are loaded onto and removed from carriers at multiple transfer points throughout the body shop.
Fully automated transfer without manual positioning, reliable across different carrier and part types.
Detection of carrier and part position to guide the robot for accurate, damage-free handling.
Technology: 2DLE / OSC

07

Load carrier inspection

Carriers and fixtures used throughout the body shop must be checked for correct configuration and absence of residual parts before reuse.
Prevents misloads and carrier-related defects, fully integrated into the line without additional cycle time.
Detection of part presence, carrier geometry, and correct fixture state.
Technology: FrameSense

08

Surface inspection

Body panels are inspected for surface defects at defined checkpoints before downstream processes.
High-resolution inline detection on complex curved surfaces, reduces rework downstream.
Detection of dents, scratches, weld spatter, and surface irregularities on body panels.

LEARN MORE

09

VIN embossing inspection

The Vehicle Identification Number is embossed into the body and must be verified for correctness and legibility.
100% traceability, reliable reading even on metallic embossed surfaces, direct integration into production data systems.
Optical reading and validation of the embossed VIN against the production order.

10

Gap & flush measurement

In the finish line, doors, flaps, and hoods are mounted to the body – dimensional accuracy of the gaps determines quality perception and function.
100% inspection instead of sampling, direct feedback to joining robotics.
Measurement of gap width and flush at hundreds of measuring points per vehicle.

11

Surface inspection before paint

Weld residues, sealant remains, and burrs are removed – the surface is checked for defects before entering the paint shop.
Early detection avoids costly rework after paint.
Detection of indentations, weld spatter, scratches, and surface deviations prior to painting.
