Abstract

See full text

A gap measurement device for measuring a gap between an upper plate and a lower plate in a material formed of the upper plate and the lower plate that overlap with each other in the Z-axis direction, which is the thickness direction. The gap measurement device has an ultrasonic sensor that functions as a plate thickness measurement sensor for measuring a plate thickness that is the thickness of the upper plate, a laser sensor that functions as a step measurement sensor for measuring a step that is the distance between the upper surface of the upper plate and the upper surface of the lower plate, and a calculation unit for calculating the gap between the upper plate and lower plate by subtracting the plate thickness from the step.
