Definitions
- DE 40 25 682 C2 discloses a device for measuring components, the height profile of strand-shaped components being determined by means of a laser triangulation measuring device.
- the laser triangulation measuring device has a single triangulation sensor, which is aligned with a single surface of the strand-like component and can measure the component that can be moved in the horizontal direction relative to the laser triangulation measuring device in vertical and horizontal directions. taler direction allows.
- the laser triangulation measuring device is relatively complex and is limited to the measurement of the component from one side.
- Figure 5 is a perspective view of a device according to the invention according to a fourth embodiment.
- a second method of alignment of the models each other is to use a best fit calculation. In this way, the measurement of the component 2 can be made easy to use under any orientation of the component 2 on the support Level 5.
- An evaluation of the evaluation unit 4 permits the automatic alignment of the actual model to the reference model while covering the striking reference point of the reference model with a corresponding prominent point of the actual model.
- the component 2, 20 may be formed, for example, as a sheet metal component.
- the measuring accuracy of the laser triangulation measuring device 3 or the resolution thereof may be less than 0.2 mm.
- the measuring process can be completed within one minute, whereby when measuring undercuts of the component 2, the measuring time can be extended as a result of a further measuring process.
- the triangulation sensors 9 of a second, in the direction of displacement 6 downstream measuring plane 13 '' also have like the aforementioned sensors an orientation at an acute angle to the vertical plane 30, which is parallel to the displacement direction 6.
- the optical axes of the triangulation sensors 9 of the second measuring plane 13 are oriented relative to the displacement direction 6 to the left of the vertical plane 30, so that a detection range / scanning range 32" results, which in particular is a displacement direction 6 extending transverse profile 33 '' on the right side detected.
- the triangulation sensors 9 of the second measuring plane 13 are mirrored on the vertical plane 30 to the triangulation sensors 9 of the first measuring plane 13 '.
- the triangulation sensors 9 of a measurement plane 13 ', 13'',13''', 13 IV can also be oriented differently with respect to the vertical plane 30 and / or the vertical plane 31.
- the triangulation sensors of a measuring plane operate in different wavelength ranges, with detection or calculation of the component taking place in a plurality of individual coordinate systems assigned to the triangulation sensors.
- the number of triangulation sensors depends on the size and geometry of the component. For example, a first triangulation sensor of the first measurement plane in a wavelength range of 620 nm, a second sensor of the same measurement plane in the wavelength range 640 nm, and a third sensor of the same measurement plane in a range of 660 nm can operate.
- the image data (actual data) acquired by the sensors are combined in a common overall coordinate system of the evaluation unit and then compared with the desired data of a CAD model or a reference model of the component previously detected by the triangulation sensors. This advantageously avoids undesired mutual interference of the measurement result in a measuring plane as a result of the overlapping of the regions of the component detected by the individual sensors.
- the triangulation sensors may be based on structured light or on a photogrammetric basis.
- the triangulation sensors can also have 3D cameras, by means of which flash-light transit times are evaluated.
- the triangulation sensors are preferably arranged calibrated and have a fixed relative position to each other.
- the orientation of the triangulation sensors 9 toward the component 2 can be fixedly set from the desired data so that the actual geometry of the height and transverse profiles of the component 2 can be detected optimally.
- the adjusting device 40 may have adjusting means, so that the triangulation sensors 9 are mounted so as to be pivotable about a rotation axis 45, whereby the rotation axis 45 runs perpendicular to the longitudinal axis 42 of the traverse 43.
- the axis of rotation 45 extends in the horizontal direction. In this way, an improved alignment of the triangulation sensors 9 on the component 2 can take place.
- the sensors 9 may each be associated with a stepping motor, the sensors 9 being discretely rotated, preferably under equidistant movement.
- the adjusting means for the carrier plate 44 and the individual sensors 9 can also be designed such that the carrier plate 44 or the sensors 9 are adjusted continuously about the longitudinal axis 42 and the axis of rotation 45, respectively.
- Servo motors can be used for this purpose.
- the position of the component 2 can be determined by means of a first workerssscannlaufes, wherein the triangulation sensors 9 are in a starting position.
- a second main scanning takes place, whereby an automatic alignment of the triangulation sensors 9 on the component 2 takes place with adaptation to the nominal data of the reference model for determining the actual data of the component 2.
- the orientation of the triangulation sensors 9 is dynamically adapted to the SoIl data. In this case, the detection of the vertical and transverse profiles of the component 2 can be further optimized.
- Adjustment 40 also have adjustment means, so that in a first surgeriessscannlauf only the La ge and the dimension of the component 2 without taking into account the desired data of the same are determined.
- the measurement point data (actual data) of the component 2 are detected under a fixed arrangement or with movement of the triangulation sensors 9.
- the embodiment of the device according to FIGS. 5 and 6 enables an improved and in particular faster scanning of the component 2.
- the triangulation sensors 9 can be designed as video sensors in order to be able to detect the position and orientation of the component 2 in a relatively short time.
