Detecting Black Parts on Black Door Panel
Banner’s Q4X problem-solving triangulation-based laser sensor has no difficulty detecting dark targets on dark backgrounds when there is a height difference. The Q4X provides a reliable sensing solution with best in class excess gain and makes pass/fail judgments based on distance rather than color or reflectivity.
A door panel has four areas where foam should be present, so four Q4X sensors are set up to target these areas and confirm proper assembly by the operator. In this case, three targets are verified, but the fourth is missing. A fail signal is sent to alert the operator that the part needs to be reworked before releasing it from the assembly station.
Along with reliable sensing on challenging targets, the Q4X is extremely durable with a stainless steel housing that resists mechanical impact, vibrations and over tightening. The setup is simple with clear user feedback on the four-digit angled display and set-up buttons located on the back of the Q4X housing.
