Title: DEVICE AND METHOD FOR ASSIGNING A TOOL TO A WORKPIECE
Abstract:
The invention relates to a device for assigning a tool to a workpiece that is conveyed on an assembly line. In order to improve the ability to inspect the assembly of workpieces, a device is provided which comprises, for example, at least one transmitter that is arranged in the vicinity of an assembly line, comprises a receiver that is arranged on the tool, and comprises an evaluation unit, which determines a corresponding distance of the tool to each transmitter from the propagation delay of at least one received signal. The device also comprises an indicating device, which indicates the positions of workpieces on the assembly line, and comprises an assigning unit, which assigns a tool or a tool position to a workpiece based upon the at least one distance of the tool to the transmitter and to the positions of the workpieces. Naturally, the arrangement of transmitters and receivers can also be selected in a transposed manner.
