Inline quality control on a sensor rake

A sensor rake monitors whether the cast part removed from the die casting machine by the robot is complete and whether any overflow is present. If the part is acceptable, it is placed on a synchronized slat conveyor, where a fan cools the cast part. Depending on the particular cast part, the sensor rake can consist of multiple W12-3 photoelectric proximity sensors. Thanks to the background blanking feature, the robot is able to work in extremely close proximity to the sensor without causing faulty switching. Where there is an additional need for accurate parts monitoring with a 3D vision system, the TriSpector1000 is the right choice. It detects volumetric surface errors and separates and discharges the cast parts showing any surface errors of this type.
