with a laser beam centroid position tracking sensor device

摘要

A centroid position tracking sensing device using the laser beam is provided to improve the effectiveness and safety of operation as the centroid of work piece can be rapidly found. A centroid position tracking sensing device using the laser beam comprises: a laser scan head(10); a controller part(20); a wireless external control panel; and a reflecting member(40). The scan area is scanned with the laser beam. The centroid of work piece is found by finding a reflector which is put on the centroid point of work piece.
