Problems solved by technology

But such tensioning devices are relatively expensive and their use is extremely time-consuming
Such devices and methods are thus essentially unsuitable, especially for sequential processes in the multiple manufacture of piezoelectric transducers

Embodiment Construction

[0029] FIG. 1 schematically shows a longitudinal section through a piezoelectric transducer 1 which can be produced using the production devices 2 a and 2 b shown in the other figures. This is an embodiment as a piezoelectric bending transducer, but the invention is not limited to this type of piezoelectric transducer 1 .

[0030] The piezoelectric transducer 1 has a layer structure with a first substrate in the form of a carrier substrate 2 and a second substrate in the form of a piezoelectric substrate 3 . The two substrates 2 , 3 each have a planar extent and are placed one above the other in a layer direction 4 perpendicular to their extent plane and are bonded together by means of an adhesive 5 arranged between them, in particular layered. connected to each other.

[0031] The carrier substrate 2 has magnetic properties, in particular ferromagnetic properties. In this embodiment it is made of steel.

[0032] The piezoelectric substrate 3 has, as a core, a piezoelectric b...

Abstract

Several layers of substrates in the form of magnetic support substrate (2) and a piezo-electrically activated piezoelectric substrate (3) are stacked with each other along the layering direction (4) and are fixed with each other along the layering direction, by using an adhesive (5), to form a substrate assembly (17). The substrates are clamped with each other by pressing each other through an electromagnetically generated magnetic force. An independent claim is included for an arrangement for production of piezoelectric transducer.

Description

technical field [0001] The invention relates to a method for producing a piezoelectric transducer having substrates in the form of a magnetic carrier substrate and a piezo-electrically excitable piezoelectric substrate, each stacked one above the other in the layer direction, the substrates being The adhesive located between them is fixed to each other, wherein the two substrates are laminated on top of each other to form a substrate assembly after prior application of an adhesive on at least one of the substrates, and are tensioned against each other in the layer direction. [0002] The invention also relates to a device for producing a piezoelectric transducer having a substrate in the form of a magnetic carrier substrate and a piezoelectrically excitable piezoelectric substrate, each stacked one above the other in the layer direction, The substrates are fixed to each other by means of an adhesive located between them, the device having at least one tensioning device, by mea...
