Protection device for movement security over axles of adjustable robotic arm of e.g. mobile robot in automobile industry, has optical photonic mixing device sensors provided around robotic arm for contactlessly monitoring movement chamber

摘要

The device has optical photonic mixing device sensors (32) provided around a robotic arm (14) for contactlessly monitoring a movement chamber, where the sensors are positioned with swivelling and rotatably adjustable sensor rings (30). The sensor rings are pivoted on a centrally adjustable ring (26) at a rotational axis (16) of the robotic arm over a pivotal axis (28) that lies in a processing direction, where the pivotal axis of the rings is provided axis-parallel to a pivotal axis (22) of the robotic arm. The sensors act in a plane of the sensor ring on both sides.
