Abstract
The invention relates to a workpiece carrier device (1) for holding and moving workpieces (15), having: a workpiece carrier (2) for receiving workpieces (15), which is mounted on a main frame (4) so as to rotate about an axis (3); a drive part, which can likewise rotate about the axis (3) relative to the workpiece carrier (2); and multiple workpiece holders (5), which are arranged on the workpiece carrier (2) in a ring around the drive axis and are mounted on the workpiece carrier (2) so as to rotate about holder axes (6) which are spaced from the drive axis. The holder axes (6) run in such a way in relation to the axis (3) that the workpiece holders (5) form a conical crown arrangement (7). The invention further relates to a coating method using the workpiece carrier device (1) according to the invention and to workpieces or substrates (15) coated by means of the coating method (e.g, pins, pen injectors, balls, ball pins, pistons, nozzle needles etc.).
