Predator3D Bead Inspection at Automate Show 2017 with Yamaha Robotics

Predator3D is the latest 3D machine vision technology from Coherix for structural adhesive and dispensing sealant bead inspection. Smart, automatic and affordable, Coherix is leveraging its SHARK platform technology, 3D experience, and i-Cite software to bring this low-cost, high-performance 3D bead inspection solution to market.

The size, shape, position and quality of beads are critical to assure structural integrity. To provide reliable inspection results, Predator3D measures and inspects bead height, width (volume) and position continuously. It also detects skips and neckdowns where material is deposited with insufficient volume.
