Abstract

The invention discloses a strainometer AOI defect identification detection device. The device comprises a vertical aluminum alloy frame of which the top is provided with an installing plate, the installing plate is provided with a motion scanning part and a curtain projection part, the motion scanning part is provided with an optical amplifier assembly for projection and an image acquisition part, a light source system in the frame projects strainometer images to the curtain projection part line by line through the optical amplifier assembly. The image acquisition part utilizes projection data of the curtain projection part to carry out strainometer defect detection. The device prevents strainometer damage, effectively prevents detection missing, greatly improves strainometer defect identification detection efficiency, reduces labor intensity, has a wide application range, utilizes a LED light source backlight illumination imaging method, greatly improves projection imaging definition and resolution and effectively reduces mechanical oscillation-caused strainometer sensitive grid imaging distortion.

Description

【Technical Field】 [0001] The invention belongs to the technical field of automatic machinery, and relates to a defect recognition and detection device, in particular a strain gauge AOI defect recognition and detection device. 【Background technique】 [0002] Strain gauges are transducers that can convert strain on engineering components, that is, changes in dimensions into changes in resistance. Strain gauge is generally composed of sensitive grid, lead, adhesive, base layer and surface cover layer. The application range of strain gauges is very wide. Applicable structures include aviation, bridges, roads, various mechanical equipment, buildings, etc.; applicable materials include various metallic and non-metallic materials. The appearance size of the strain gauge is small, the length and width of the base are only a few millimeters, and the internal structure size of the strain gauge is small, generally the grid width is 25-40μm, and the grid spacing is 40-60μm. [0003] Common s...
