Sealing gaskets on electrical modules help minimize failure in vehicles. A robot equipped with a glue nozzle applies adhesive, which must be inspected. Manual inspection is challenging because it is difficult to view the bead’s complete path and calculate its volume. The integrity of the gasket may be compromised if the bead of glue is too thin, in the wrong position or contains gaps.
Cognex 3D vision systems automate the glue bead inspection process by accurately locating the glue bead position, detecting any bead gaps and measuring bead width and volume. This automated process reduces product failure rates and increases inspection speed.
