APPARATUS FOR CHECKING ADHERENCE STATE OF FIBER REINFORCED PLASTIC TAPE

摘要

An apparatus for checking an adherence state of fiber reinforced plastic tape includes an illuminating section having first and second illuminating groups. The main optical axes of illumination light beams of light emitting sections of the first illuminating group are set at a designated inclination angle with respect to a surface of an imaging region and distances on the main optical axes between a surface of a structural object and each of the light emitting sections are set to be the same. The main optical axes of illumination light beams of light emitting sections of the second illuminating group are set at an inclination angle different from the first illuminating group with respect to the surface of the imaging region and distances on the main optical axes between the surface of the structural object and each of the light emitting sections are set to be the same.

1. An apparatus for checking an adherence state of a plurality of strips of fiber reinforced plastic tape that is adhered and lined up on a surface of a structural object, the apparatus comprising:
an imaging section configured to image an imaging region with a line shape that is set on the fiber reinforced plastic tape; an illuminating section configured to radiate illumination light toward the imaging region; a checking section configured to check the adherence state of the fiber reinforced plastic tape based on an image that is imaged using the imaging section; and a moving section configured to move the illuminating section and the imaging section to with respect to the fiber reinforced plastic tape that is adhered in a relative movement direction, the imaging section further having a line sensor in which a plurality of light detection elements are aligned in a direction that intersects with the relative movement direction, the illuminating section further having a first illuminating group with a plurality of light emitting sections that are arranged to line up in a direction that intersects with a fiber direction of the fiber reinforced plastic tape, the first illuminating group being configured such that main optical axes of illumination light beams that are radiated from each of the light emitting sections of the first illuminating group are set at a designated inclination angle with respect to a surface of the imaging region and distances on the main optical axes between the surface of the structural object and each of the light emitting sections of the first illuminating group are set to be the same, the illuminating section further having a second illuminating group with a plurality of light emitting sections that are arranged to line up in a direction that intersects with the fiber direction of the fiber reinforced plastic tape, and the second illuminating group being configured such that main optical axes of illumination light beams that are radiated from each of the light emitting sections of the second illuminating group are set at an inclination angle, that is different from the first illuminating group with respect to the surface of the imaging region and distances on the main optical axes between the surface of the structural object and each of the light emitting sections of the second illuminating group are set to be the same.
