Abstract
An apparatus for positioning a workpiece carrier in a machining station includes at least one positioning device. The workpiece carrier is movable on a rail system and one or more machining stations are arranged along the rail system for machining a workpiece arranged on the workpiece carrier. The at least one positioning device is arranged in an area of the machining station and has fixtures for positioning and high-precision retention of the workpiece carrier with respect to a stationary reference surface. The positioning device further includes fixtures for decoupling the workpiece carrier from the rail system, and a deceleration and acceleration device for the workpiece carrier.

A method for positioning a workpiece carrier in a machining station, wherein the workpiece carrier is movable on a rail system and a machining of a workpiece arranged on the workpiece carrier takes place in at least one machining station arranged along the rail system, comprising:
- individually operating a workpiece carrier within the rail system, wherein the workpiece carrier is self-driven by a drive motor mounted on the workpiece carrier;
- introducing the workpiece carrier to a machining station;
- decelerating the workpiece carrier with a deceleration device while introducing the workpiece carrier to a positioning device;
- positioning the workpiece carrier relative to a stationary reference surface using the positioning device;
- uncoupling the workpiece carrier from the rail system within the machining station;
- precisely holding the workpiece carrier in place while being decoupled from the rail system;
- machining the workpiece;
- releasing the workpiece carrier from the positioning device;
- accelerating the workpiece carrier to a predetermined initial velocity using an acceleration device while leaving the positioning device;
- and
- moving the workpiece carrier along the rail system.
