3D Adhesive Bead Inspection Laser Sensor

Increasing demands for product quality and, as a result, high-quality adhesive bonds are becoming ever more important in the automotive industry. With RTVision.3d from QUISS, it is now possible not only to measure the width, position, and continuity of the bead application but also its height. This provides insights into the applied material volume.

RTVision.3d is based on laser sensors with integrated cameras and can cover various application types and patterns. The robust and compact design allows the system to be flexibly adapted to any inspection task.

Automatic Bead Tracking

The 100% 3D inline solution can be used to monitor applications in bodywork, particularly the safety-critical structural adhesive bonds. RTVision.3d is also the ideal solution for quality inspection in battery production. It can prevent unacceptable defects in cell adhesion, for example. It can even precisely check the width, height and position of triangular beads.

The sensor provides 360° application coverage ensures 100% bead inspection incorporating 6x laser triangulation for maximum curve coverage providing inline monitoring for outstanding quality without additional cycle time. Extrinsic calibration enables traceability to robot coordinates with robot speeds up to 600 mm/s while delivering point cloud analysis for precise quality inspection. The sensor can be operated at working distances of 85 mm to 245 mm delivering high-precision glue bead detection up to 0.1 mm.
