  • Optical device for detecting quality of welding gun electrodes
    Patent number: 9417192
    Abstract: An optical device for detecting quality of welding gun electrodes An optical sensor device comprises a housing (10) with a pair of openings (11, 11a) communicating with a pair first (14) and a second (15) seat for accommodating a respective one of a pair of electrodes (E1, E2). A first set of lights (16, 17) emit a first (L1) and a second (L2) light beam in an intermediate geometric plane (p1) between the seats (14, 15). Two oblique reflecting elements (25, 26), interposed between the two seats (14, 15), to reflect the first (L1) and second (L2) light beams in two opposite directions perpendicular to the geometric plane (p1) toward the first and the second seats. Other lights (47, 32) emit third (L3) and fourth (L4) light beams on opposite sides of the geometric plane (p1) to illuminate the first and the second seat (14, 15).
