Abstract

Ein Verfahren zum Herstellen eines Ultraschallprüfkopfes mit einer Ultraschallwandleranordnung (200) mit einer gekrümmten Sende- und Empfangsfläche (23), die aus einer Mehrzahl nebeneinander angeordneter Wandlerelemente (14) aufgebaut ist, umfasst gemäß der Erfindung folgende Verfahrensschritte:
a) eine den Außenabmessungen der Ultraschallwandleranordnung entsprechende piezoelektrische ebene Platte (2) wird mit einer ihrer Flachseiten (2a) auf eine Folie (4) aus einem Polymer aufgeklebt,
b) in die der Folie (4) abgewandte Flachseite (2b) der piezoelektrischen Platte (2) werden vor oder nach dem Aufkleben auf die Folie (4) Nuten (12) eingebracht, deren Tiefe zumindest annähernd der Dicke der Platte (2) entspricht, so dass eine aus einer Mehrzahl nebeneinander angeordneter Wandlerelemente (14) bestehende ebene Ultraschallwandleranordnung (20) entsteht,
c) anschließend wird die ebene Ultraschallwandleranordnung (20) mit ihrer mit der Folie (4) verklebten Flachseite (2a) auf eine gekrümmte Auflagefläche einer Biegeeinrichtung (22) aufgebracht und dort in eine gekrümmte Form gebogen.

A method for producing an ultrasonic test head with an ultrasound transducer arrangement (200) having a curved transmitting and receiving surface (23), which is constructed from a plurality of juxtaposed transducer elements (14) comprises according to the invention the following method steps:
a) a piezoelectric flat plate (2) corresponding to the outer dimensions of the ultrasound transducer arrangement is glued with one of its flat sides (2a) onto a foil (4) made of a polymer,
b) in the film (4) facing away from flat side (2b) of the piezoelectric plate (2) are introduced before or after sticking to the film (4) grooves (12), the depth of which corresponds at least approximately to the thickness of the plate (2) such that a plane ultrasound transducer arrangement (20) consisting of a plurality of mutually juxtaposed transducer elements (14) is formed,
c) then the planar ultrasonic transducer assembly (20) with its adhered to the film (4) flat side (2a) is applied to a curved support surface of a bending device (22) and bent there in a curved shape.
