Laser plotter and method for engraving marking and/or inscribing a workpiece

摘要

The invention describes a laser plotter and a method for engraving, marking or inscribing a workpiece. Two lasers are installed in a housing of the laser plotter and may alternatively operate on the workpiece. The workpiece is positioned on a processing platform and a laser beam is sent to at least one focusing unit configured for both lasers, from which the laser beam is deflected in the direction of the workpiece. Control of the workpiece is obtained by software running in a control unit. Graphic and/or text data are prepared on an external computer or other control device, and transferred to the control unit of the laser plotter. The lasers are allocated to the transferred data based on color code, whereby a height correction value to compensate for the various focal lengths of the lasers is preloaded in the data bank for the different colors.

主权项

1. A laser plotter for engraving, marking and/or inscribing workpieces, consisting of a processing platform for positioning the workpiece, at least two radiation sources in the form of lasers with at least one deflecting element and a movable focusing unit and a control unit to control the individual elements, wherein the control unit is configured to receive data produced by an external component, from a graphic and/or a text, and a data bank is provided for converting the transferred data, characterized in that the different radiation sources are allocated by color or a color code to transfer the graphic and/or the text, whereby a correction value for the various positions, as a height correction value for the various radiation sources, is preloaded in the data bank for the various colors.
