Abstract
The invention concerns a workpiece carrier (4) for a production unit (1) with at least one conveying section (2). The workpiece carrier (4) comprises a workpiece carrier body (13), a workpiece receptacle (16) arranged on the workpiece carrier body (13), a guide device (14) which is arranged on the workpiece carrier body (13) by means of which the workpiece carrier (4) can be received and displaced in the production unit (1), in particular in the conveying section (2), and a code element (20) which is arranged on the workpiece carrier body (13) which is designed to identify the workpiece carrier (4) by means of a detection means (11) arranged in the production unit (1). For identification, the code element (20) has inhomogeneous material properties in its longitudinal orientation. During a relative movement of the code element (20) in the longitudinal orientation (23) relative to the detection means (11), the inhomogeneous material properties of the code element (20) can be detected by the detection means (11) and the workpiece carrier (4) can be identified.
