Embedded Vision Propels Bead Inspection

Facebook X LinkedIn Email
DAVE KELLY AND ANDRES TAMEZ, COHERIX INC.

Automotive designers are more frequently turning to structural adhesives as a solution for strengthening, structurally optimizing and lightweighting automotive bodies. These adhesives enable mixing material types to achieve lightweight structures while meeting goals for safety, noise, vibration and harshness. Vehicle assemblies may now contain hundreds of adhesive beads. The dramatic increase in dispensed meters of these beads is driving a need for cost-effective, real-time, 100 percent 3D bead inspection. The inspection objective is to speedily and accurately detect and locate gaps and...Read full article

    laser triangulation
    A technique that uses a solid-state laser and a detector to determine an object's relative distance to the system. The laser beam is projected onto the target and then reflected onto a detector through the means of focusing optics. When the laser beam moves on the detector, information is stored into binary code to later be processed and used for calculating the relative distance.
