  • sealing profiles are intended, for example, to produce a sealing connection between a body opening and the body part inserted in it.
  • the sealing profiles can be attached either on the body side or on the body side or on both sides.
  • a body part may be, for example, a door, a boot lid or a sunroof element.
  • it is either a matter of applying a sealing profile on or in a door opening, for example of a body, and of measuring the applied sealing profile with respect to its correct position.
  • a sealing profile can also be applied to an outside of a vehicle door-that is, on the side of the body part-which is then inserted into the door cut-out of the body in an assembly situation.
  • the sealing profile is glued onto an adhesive flange of either the door cutout or the vehicle door, for example with a so-called application head.
  • An adhesive flange is generally the area of a body flange or door flange to which the sealing profile is applied.
  • the position of the adhesive flange on the one hand and the position of the applied sealing profile on the other hand by complex optical or image-based methods are detected, for example by means of a laser or directly on the component with the simplest means by eye, which include, for example, gauges, templates or scribing , and measured by the use of a tape measure. While gross outliers can still be detected, this procedure is too imprecise for an accurate measurement and impractical as a basis for taking corrective action. In addition, no statistical analysis for the documentation of quality control can be based on this.
  • image-based Method may be mentioned DE 102016 203 842 A1, which describes a detection device, for example with a CCD sensor.
  • image-based methods have the disadvantage that, although an image is generated, it must subsequently be subjected to an evaluation in order to be able to make a statement, for example, for compliance with positional tolerances.

  • the sensing device comprises at least one switch which is configured as a breaker and emits a switching pulse in contact with a clotting conditions contact force.
  • the position of the receiving interface detected at the time of this switching pulse is stored so that the precise geometric location of the scanned surface of the sealing profile is determined by the fixed geometric relationship between the exception interface and the location where the sensing device is located during the switching pulses can be determined or calculated.
  • An advantageous embodiment of the method provides that the handling device as needed an Ard a reference point with absolute coordinates for calibrating the position data of the recording interface. This increases the measurement accuracy. In addition, a quick recalibration of the handling device is possible with a partial replacement of the body part.
  • An advantageous embodiment of the method provides that a plurality of probe tips is provided via the sensing device and is scanned over each of the probe tips at least one of the location points to be measured. As a result, the measuring time for the measurement of a body component is reduced, since the individual probe tips are preferably distributed over the circumference to be measured, so that the respective movement which the handling device has to perform until a probe tip is present can be small.
  • An advantageous embodiment of the method provides that the probe tips are brought before scanning the respective position point by a translational movement and / or by a rotational movement in a predominantly orthogonal position with respect to the position to be measured point of the sealing profile.
  • the orthogonal position ensures that each probe tip detects the surface to be sensed already due to a very low contact force and generates a switching signal.

If the sealing profile 4 is such that it projects beyond the line 18 to the right, a good sealing of the vehicle door is achieved in principle, but at the cost of a greater closing force of the door, which is not acceptable from the customer's point of view.
