Abstract:
An electronic parts mounting machine comprising:a parts feeding section having means for feeding electronic parts;a xy table for holding a circuit board having electronic parts mounted thereon and positioning the circuit board at a desired position;a vertically movable mounting head for sucking and recognizing an electronic part and mounting it on a circuit board;a suction nozzle for sucking electronic parts;a nozzle rotating means for rotating the suction nozzle;a regulating unit for regulating the electronic part, which has been sucked by the suction nozzle, for centering the electronic part on the suction nozzle;a recognition camera for recognizing a sucked electronic part;a lead misalignment tester for testing electronic parts for defective leads and lead misalignment, said tester being separate from said XY table;linear driving means for linearly driving a test unit of the lead misalignment tester; andcontrol means for rotating the suction nozzle during lead misalignment testing while controlling the linear driving means to ensure that a test point of a test unit scans each lead of an electronic part sucked by the suction nozzle while crossing said lead.
