Abstract
An inspection method of a suction nozzle. Air flow rates that flow in multiple reference pipes that have different sectional areas are measured. A proportionality factor between air flow rates and sectional areas of the reference pipes is calculated based on the measured air flow rates of the multiple reference pipes, and the sectional areas of the multiple reference pipes. An air flow rate in a suction nozzle that is an inspection target is measured. The sectional area of the suction nozzle is calculated based on the air flow rate of the suction nozzle and the calculated proportionality factor. The sectional area of the suction nozzle calculated in this manner is substantially fixed even when the pressure of air supplied from an air source fluctuates. The sectional area of the suction nozzle is proportional to the air flow rate that flows in an inner portion of the suction nozzle.
