Abstract

To avoid damage to carrier substrates in a device for mechanically aligning carrier substrates for electronic circuits, the carrier substrates having two main surfaces and a peripheral surface and being supplied to a horizontal fixture of the device, centering elements being forced to engage on the peripheral surface of the carrier substrates to align the carrier substrates in the horizontal fixture, it is proposed that at least two centering elements be mounted rotationally and displaceably in the axial direction on at least two first shafts that are oriented in parallel with one another and in parallel with the horizontal fixture. The centering elements engage on sections of the peripheral surface of the carrier substrate disposed opposite one another in a first direction, and at least two further centering elements engage with stop faces at sections of the peripheral surface of the carrier substrate disposed opposite one another in a second direction running perpendicularly to the first direction. The stop faces are movably supported in a direction perpendicular to the horizontal fixture.
