Inspection probe
Disclosed is an inspection probe of an inspection system that includes an ultrasonic probe that is freely movable on a test object and irradiates the test object with an ultrasonic wave to detect a reflected wave, and a calculation unit that executes arithmetic processing according to a detection result according to the ultrasonic probe to acquire a flaw detection result of the test object. The inspection probe includes a chassis that is freely movable on a sheet material where a two-dimensional pattern disposed on the test object and indicating a position on the test object is drawn. The ultrasonic probe is fixed to the chassis so that an incident point of an ultrasonic wave that is incident onto an opposing surface of the test object from the ultrasonic probe is within an angle of view of the reader which reads the two-dimensional pattern.
1. An inspection system comprising:
a sheet material which is disposed on a test object and on which a two-dimensional pattern indicating a position on the test object is drawn; and
an inspection probe that includes:
a chassis that is freely movable on the sheet material and has transparency and sonic wave permeability;
an ultrasonic probe that is freely movable on the test object and irradiates the test object with an ultrasonic wave to detect a reflected wave, and is fixed to the chassis;
a reader that is fixed to the chassis and reads the two-dimensional pattern, the reader having a predetermined angle of view; and
an illumination that is fixed to the chassis; and
a calculation unit that executes arithmetic processing according to a detection result according to the ultrasonic probe to acquire a flaw detection result of the test object,
wherein the ultrasonic probe is fixed to the chassis such that an incident point of an ultrasonic wave that is incident onto an opposing surface of the test object from the ultrasonic probe is within the angle of view of the reader.
2. The inspection system according to claim 1 ,
wherein the illumination is fixed to the chassis such that an incident angle of illumination light that is incident onto the test object from the illumination is larger than an incident angle of the ultrasonic wave that is incident onto the test object from the ultrasonic probe.
3. The inspection system according to claim 1 ,
wherein the illumination is fixed to the chassis such that illumination light that is emitted from the illumination and is reflected from the opposing surface of the test object without being incident onto the test object and reflected light of the illumination light that is incident onto the test object are not incident onto the reader.
4. The inspection system according to claim 1 ,
wherein the illumination is fixed under the reader.
5. The inspection system according to claim 1 ,
wherein the chassis is formed of a single solid acrylic resin.
