Abstract
In an optical probe head 1 which is configured to check a weld or a glue joint immediately after being produced there is a risk of contaminating the probe head through the production process of the joint. In order to prevent this protective devices are proposed according to the invention that are configured either as a rotor 33 rotating in front of the windows 8, 9 of the probe head 1 or as a transparent protective device arranged in front of the windows 8, 9 of the probe head 1, for example a transparent protective foil 16 that is being moved along.
Claims14
A protective device for a touch free, optical probe head (1) transmitting electromagnetic radiation, in particular light beams from an outlet window (8) and/or receiving them through an inlet window (9) for testing purposes caused by a control, which protective device (18) comprises:
- a rotor (33) with rotor blades (35) that is drivable in a controlled manner and which rotates in front of the outlet window (8) and/or the inlet window (9) and is driven so that a pass through of the light beam and/or of the reflected beam occurs in a time coordinated manner exactly in the intermediary space between two sequential rotor blades (35) of the rotating rotor (33) and a drive and a rotation position detection of the rotor (33) is coupled with the control of the optical probe head (1).
The protective device according to claim wherein the rotor axis (34) is arranged between the inlet window (9) and the outlet window (8) of the probe head (1) and the rotor (33) covers both windows.
A protective device for a touch free, in particular optical probe head (1) transmitting electromagnetic radiation, in particular light beams from an outlet window (8) and/or receiving them through an inlet window (9) for testing purposes caused by a control, comprising:
- at least the inlet window (9) and/or the outlet window (8) of the probe head (1) is protected by a radiate able, in particular transparent protective device (18).
