Definitions
- test specimens a device for the contactless detection of structural and / or surface defects of large-area bodies, in particular plate-shaped materials (hereinafter "test specimens").
- Point measuring systems such as B. ultrasound, radiometric, inductive or capacitive methods provide information about the
- DE 1 97 03 484 A1 discloses a test method in which internal defects are detected in a material or composite of materials by generating a heat flow in the area to be examined which is disturbed at defects. The resulting distortions in the surface temperature field are recorded and evaluated for error contrasting. Sensitivity to smaller and deeper internal faults is achieved through optimized heat management and through the use of high-resolution measuring equipment to record the local and temporal surface temperature distribution.
- DE 1 96 28 391 C1 discloses a signal processing unit of a device for photothermal testing of a surface of a test specimen.
- a speed measuring device is provided which can be used to determine the relative speed of a test specimen with respect to the optical part and a detector which is fixedly arranged thereon. With the speed measurement value obtained in this way, the temporal course of induced thermal radiation generated by excitation radiation can be corrected to a stationary test area.
- DE 1 97 20 461 A1 discloses a method and a device for checking the inner cooling structure of a turbine blade. An output thermographic image of the turbine blade to be tested is recorded by means of a first infrared camera. The turbine blade is then briefly heated by blowing hot air into its cooling structure.
- thermographic image of the heated turbine blade is then recorded by a second infrared camera.
- the infrared thermography camera can work in a line scan mode, i.e. scan the object line by line.
- the time course of the temperature distribution recorded by the camera is digitized online by a personal computer using a corresponding evaluation and image processing program, and the output thermographic image is substituted in each case.
- DE-OS 1 648 349 discloses a device for non-destructive material testing of rolling stock after a rolling process and during a change in temperature of the rolling stock.
- a contactless temperature sensor is arranged at a distance from the rolling stock, which delivers a signal according to the temperature of the rolling stock surface to an evaluation device, which triggers a switching process as soon as the signal changes beyond predefined limit values.
- the temperature sensor can detect infrared radiation from the rolling stock surface be an appealing radiometer, which is focused on a certain part of the surface of the rolling stock, so that the signal is a function of the temperature of this surface part.
- the surface part observed in each case can never follow a scan on the surface of the rolling stock, the signal obtained then corresponding to the temperature profile along this scan line.
- a lens system is always focused on a relatively small scanning spot on the surface of the rolling stock, this lens system concentrating the radiation from this spot on the infrared cell.
- Radiometer is moved back and forth in order to move the scanning spot across the rolling stock, a wide cooling nozzle is arranged on the side of the rolling stock facing away from the radiometer, which directs a curtain of coolant against the lower surface of the rolling stock and thus cools the lower surface thereof.
- EP 0 093 422 A2 discloses a device which is only intended and suitable for the contactless detection of surface defects.
- a Fairchild semiconductor line scan camera with 2,048 pixels is used for this purpose, with the slab surface to be detected being illuminated with mercury vapor lamps in order to improve the image recordings.
- US Pat. No. 4,168,430 discloses a device for the contactless detection of welding spots which have just been produced with the aid of a special video camera which responds to infrared radiation and which is attached to the head of the welding device. The heat curve that propagates from the checked welding point in the workpiece surface is then detected. The thermal image obtained in this way is then compared with a reference image of a reference welding point previously produced under the same conditions.
- the invention is based on the object of developing a device for carrying out a method which is improved compared to the previously known methods, in particular with regard to the test speed, and which also enables the detection of test specimens with poor thermal conductivity (for example wood and wood-based materials).
- the test specimens to be examined come heated from one Production process, for example from a heating press.
- this process heat which is emitted essentially by convection from the surface of the test specimen to the cooler environment, is used to detect the test specimen surface.
- Adhesion defects or delaminations in the material hinder the heat transfer to the surface, which thus appears much cooler than the surroundings over the defects.
- This difference in heat on the surface of the test specimen is detected with a thermography camera, which can be a line scan camera or an area scan camera.
- the cooling unit is provided in order to accelerate the heat dissipation to the environment and thus the cooling of the body surface to be detected, in order to achieve a faster detection of the adhesion defects. It is advantageous here if the cooling unit is a cooling register which extends transversely to the direction of displacement and is linear or strip-shaped cooling air which blows onto the surface of the test specimen to be detected.
- the drive for the relative displacement is a conveyor belt that feeds the test specimen under the stationary thermography camera. It is then advantageous if the thermographic camera, viewed in the conveying direction, is arranged at a distance behind the production line that heats the test specimen, e.g. by far behind the outlet of a heating press.
- thermography line or surface camera is attached at such a height above the surface of the test specimen to be measured that the surface to be examined can be observed with the appropriate optics.
- the lines of the line camera or the lines of the area camera are aligned so that they convey the thermal image of the material uniformly under the thermographic camera perpendicular to the direction of travel of the conveyor belt, which can also be a V-belt conveyor, a driven roller conveyor or the like Test body takes up. An image of the entire test specimen is then built up from the individual lines in a connected computer. The thermal images obtained with the aid of a cell camera or the individual lines of a flat panel camera can be evaluated in an identical manner.
- thermography camera Thermal conductivity
- adjustment devices are provided for changing the distance between the cow unit and the thermographic camera to be measured in the direction of displacement and / or for changing the relative speed between the test specimen and the thermographic camera and / or for changing the distance of the cow unit from the one to be loaded Surface of the test specimen and / or for the performance of the cow unit
- a freely rotatable roller intended for resting on the surface of a plate-shaped test specimen can also be provided as a cow unit, the axis of rotation of which lies transversely to the displacement of the test specimen, that is to say parallel to the camera line mentioned, because the direct contact between the roller and the test body results in heat from the test body surface derived into the role acting as a cow unit.
- the roll itself can be equipped with a cooling device, for example with a cooling water system.
- An exemplary embodiment of the invention is shown in the drawing in the form of a diagram.
- the drawing shows a conveyor 1 in the form of a conveyor belt for a plate-shaped test specimen 2, which is e.g. can be a coated chipboard.
- the conveying device 1 the conveying direction of which is indicated by an arrow F, is arranged behind a production line 3, which is schematically represented by e.g. pull-out rollers arranged at the outlet of a heating press is shown.
- a cooling unit 4 which extends transversely to the conveying direction F, is arranged in a stationary manner above the conveying device 1, said cooling unit 4 forming the surface to be detected of the test specimen 2 conveyed beneath it in a line or strip, e.g. charged with evenly cool air.
- thermography camera 5 Seen in the conveying direction F, the cooling unit 4 is followed by a thermography camera 5, which is shown in the drawing as an area camera, but can also be a line camera. Like the cooling unit 4, the thermography camera 5 is arranged stationary above the conveying plane and is aligned with its at least one camera line o transversely to the conveying direction F. A computer is connected to the thermography camera 5, the computer 6 of which builds up a separate thermal image pattern from each camera line, which pattern can be viewed on a color monitor 7 and evaluated on a PC.
- the drawn double arrow 8 symbolizes an adjusting device for changing the distance to be measured in the conveying direction F between the cooling unit 4 and the thermographic camera 5.
- the latter can be designed as a scanning system or as a complete line or area camera (focal plane array).
- thermography camera 5 is attached in a stationary manner at such a height above the conveyor device 1 that with the appropriate optics investigating surface of the test specimen 2 can be observed.
- the camera line oriented transversely to the conveying direction F records the thermal image of the test specimen passed in a continuous movement under the cooling unit 4 and then under the thermography camera 5, an image of the entire surface then being obtained from the individual line recordings in the connected computer 7, 8 of the test specimen 2 is built.
- the depth layer of the test specimen 2 to be examined is determined by the distance setting of the thermography camera 5 relative to the cooling unit 4 in connection with the speed of the conveyor device 1.
- the camera When using a thermographic surface camera, the camera is mounted at such a height above the test specimen 2 to be measured that the desired width of the surface of the test specimen 2 is imaged with the appropriate optics.
- the individual lines of this area camera are also arranged one behind the other transversely to the conveying direction F and in the conveying direction F. Due to the uniform movement of the test specimen 2 under the surface camera 6, a separate image of the test specimen is built up from each camera line in the connected computer 7, 8. This creates as many thermal images of the test specimen as the camera has lines. Since each camera line records a somewhat more distant area of the test body 2 from the cooling unit 4, the respective line images contain information from different depth levels 10 of the test body 2, as is indicated in the lower part of the figure. In relation to the surface camera shown, a section 2a of the test specimen 2, shown on an enlarged scale, shows n lines 11, which convey information from different depth planes 10.
