APPARATUS AND METHOD FOR TEST DETECTION OF SECONDARY BARRIER

摘要

A defect inspection device and inspecting method of a second barrier are provided to more accurately detect the defect generated in a sealing adhesion part of the second barrier with an ultrasonic sensor. A defect inspection device and inspecting method of a second barrier comprises an input sensor(100) vibrating a bonding surface of a supple triplex(26) with the ultrasonic wave by using an electric signal; an output sensor(110) converting the ultrasonic wave, propagated from the input sensor, into the electric signal; an amplifier(120) augmenting the signal detected by the output sensor; a filter section(130) accepting a fixed band from the signal detected by the amplifier; and a controller(150) determining the adhesion failure of a supple triplex based on the signal of the filter section.
