Calibration robot for automatic broad slit-nozzle, has electric screwdrivers for adjustment of adjusting screws of slit lip and retention bar, respectively, where screws respectively serve for adjustment of gap widths of lip and bar

摘要

The robot has electric screwdrivers (22, 23) for adjustment of an adjusting screw (4) of a broad slit lip and an adjusting screw (5) of a retention bar, respectively. The screws respectively serve for adjustment of gap widths of the lip and the bar. The electric screwdrivers are individually or together assembled on a portal carriage (20). A carriage drive (21) is connected to a bridge (14) by a gear wheel and a gear rod (17) and to a processor i.e. programmable logic controller, by a position sensor, so that the processor selectively approaches a position of the adjusting screws.
