Description
Verfahren und Vorrichtung zum Messen der Durchbiegung von flachen Plättchen Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Messen-der I)urchbiegung von flachen Plättchen.Method and device for measuring the deflection of flat Platelets The invention relates to a method and a device for measuring I) bending of flat plates.
Das Messen der Durchbiegung von flachen Plättchen mit Abmessungen von einigen Millimetern bis einigen Zentimetern und das Sortieren erfordern erhebliche Umsicht und einen großen Zeitaufwand. Nach den bekannten Verfahren wird nämlich zunächst mittels Spitzentaster die Plattendicke und dann zwischen planparallelen Flächen die Durchbiegung ermittelt. Ein solches Verfahren ist inebesondere bei schwankender Plättchendicke umständlich und für serienmäßiges Sortieren zu zeitraubend und kostspielig.Measuring the deflection of flat plates with dimensions from a few millimeters to a few centimeters and sorting require considerable Prudence and a great deal of time. According to the known method is namely first the plate thickness using a tip probe and then between plane-parallel ones Surfaces the deflection is determined. Such a procedure is particularly useful for fluctuating Plate thickness cumbersome and too time-consuming and expensive for serial sorting.
Die Erfindung hat sich die Aufgabe gestellt, an plattförmigen Bauteilen, insbesondere flachen Plättchen mit Abmessungen von einigen Millimetern bis einigen Zentimetern die Messung der Durchbiegung wesentlich zu vereinfachen. Erfindungsgemäß werden flache plättchenförmige Bauteile zwischen zwei planparallelen Platten geführt und die Größe des erzeugten Spaltes anschließend mittels durchfallendem Licht und einer optoelektronischen Vorrichtung gemessen. Die Größe des erzeugten Spaltes ist der Durchbiegung der Plättchen direkt proportional. Das erfindungsgemäße Verfahren ist gut als Prüfmethode, insbesondere bei serienmäßiger Fertigung von beispielsweise keramischen Plättchen geeignet. E's ermöglicht darüber hinaus durch Kopplung mit einer Schaltvorrichtung und einer Sortierklappe eine Sortierung in geeignete Plättchen und Ausschuß.The invention has set itself the task of using plate-shaped components, in particular flat plates with dimensions from a few millimeters to a few Centimeters to simplify the measurement of the deflection considerably. According to the invention flat plate-shaped components are guided between two plane-parallel plates and then the size of the gap created by means of transmitted light and measured by an optoelectronic device. The size of the gap created is directly proportional to the deflection of the platelets. The inventive method is good as a test method, especially in the case of series production of, for example ceramic platelets. E's also made possible by coupling with a switching device and a sorting flap sorting into suitable platelets and scrap.
Anhand der Figuren 1-3 ist die Erfindung naher erläutert.The invention is explained in more detail with reference to FIGS. 1-3.
Fig. 1 zeigt einen Längsschnitt durch die Einbring- und Meß-Vorrichtung.Fig. 1 shows a longitudinal section through the introduction and measuring device.
Fig. 2 zeigt die Sortierklappe.Fig. 2 shows the sorting flap.
Fig. 3 zeigt in schematischer Darstellung den Aufbau einer Vorrichtung im Sinne der Erfindung.Fig. 3 shows a schematic representation of the structure of a device within the meaning of the invention.
Die Plättchen 1 werden mittels eines Schiebers 4 zwischen zwei planparallele Platten 2 eingebracht. Zum Einatellen des beweglichen Stempels 3 ist dieser mit Stellechraube 6 und Druckfeder 16 ausgerüstet.The platelets 1 are by means of a slide 4 between two plane-parallel Plates 2 introduced. To mount the movable stamp 3 this is with Adjusting screw 6 and compression spring 16 equipped.
Lichtstrahlen fallen durch den Spalt 15. Je größer die Durchbiegung des Plättchens 1 ist desto größer ist die Weite der Austrittsöffnung 5 zwischen der Platte 2 und dem Stempel 3.Light rays fall through the gap 15. The greater the deflection of the plate 1, the greater the width of the outlet opening 5 between the plate 2 and the stamp 3.
Die Breite dieses Spaltes ist ein direktes Xaß fttr die Durchbiegung der Plättchen; Je größer die Durchbiegung ist desto größer ist der Spalt.The width of this gap is a direct measure of the deflection the platelet; The greater the deflection, the greater the gap.
Das durch den Spalt fallende Licht wird mittels einer Fotodiode 7 in einen analogen Strom umgesetzt. Dieser wird verstärkt und wie Fig. 3 zeigt, einem Trigger 8 zugeführt, der bei einer einstellbaren Schwelle (gut-schlecht) kipgt.The light falling through the gap is generated by means of a photodiode 7 converted into an analog stream. This is amplified and, as shown in FIG. 3, a Trigger 8 is supplied, which tips over at an adjustable threshold (good-bad).
Mit 9 ist ein Ventil, mit 10 ein Zylinder und mit 11 die Sortierklappe bezeichnet. 17 ist die Lichtquelle.9 is a valve, 10 is a cylinder and 11 is the sorting flap designated. 17 is the light source.
Einzelheiten der Sortierklappe 11 sind aus Fig. 2 ersichtlich.Details of the sorting flap 11 can be seen from FIG.
In dieser ist mit 10 ein Zylinder, mit 13 ein Behälter fttr Gutteile und mit 14 ein Behälter für den Ausschuß bezeichnet.In this is a cylinder at 10 and a container at 13 for good parts and at 14 denotes a container for the rejects.
Das Verfahren gestattet eine schnelle und kontinuierliche Aussortierung von flachen plättchenförmigen Bauteilen.The process allows rapid and continuous sorting of flat plate-shaped components.
