Title:
溶接シームの深さをリアルタイムで測定するための装置
Document Type and Number:
Japanese Patent JP6462140
Kind Code:
B2
Abstract:
A device for measuring the depth of a weld seam in real time during the welding or joining of a workpiece by means of radiation, including: its measuring light source, the light of which is coupled by a beam splitter into a reference arm and a measuring arm; a collimator module having at least one collimation lens for collimating a measuring light beam, which is fed to the collimator module via an optical waveguide in the measuring arm, and for imaging the measuring light beam, which is reflected from a workpiece to be processed, on an exit/entry surface of the optical waveguide; a coupling element for coupling the measuring light beam into the beam path of a processing beam; a focusing lens for the joint focusing of the measuring light beam and the processing beam on the workpiece and for the collimating of the reflected measuring light beam; and an analysis unit for determining the depth of a weld seam, into which the measuring light reflected from the workpiece is guided with the superimposed, reflected light from the reference arm. The collimator module includes a device for setting the axial focal position of the measuring light beam, and for setting the lateral focal position of the measuring light beam, and a field lens, which is arranged between the exit/entry surface of the optical waveguide and the collimation lens and defines the beam widening of the measuring light beam and therefore the focus diameter of the measuring light beam.
