Prepreg pasting state inspection apparatus

摘要

Even when a pasting target body to which prepregs are pasted has a shape changed portion such as a curved portion, prepreg pasting states are accurately inspected. A prepreg pasting state inspection apparatus (2) for inspecting a gap G between prepregs (4) adjacent on a pasting target body (3) has a laser (21) for emitting slit light LA along an inclined plane so that a projected pattern X of the slit light is formed across the adjacent prepregs (4), a camera (22) for imaging an irradiation region of the laser (21), a control unit (24) as a determination unit for determining whether the gap G between the adjacent prepregs (4) is within an allowance based on a signal from the camera (22), a range sensor (23) for measuring a distance between a reference position and the irradiation region, and focus adjusting units (25 and 26) for adjusting focus positions of the camera (22) and the laser (21) based on the signal from the range sensor (23).
