AI Technical Summary
Existing technologies are inefficient and have unstable accuracy in prepreg thickness detection, and cannot achieve full-area thickness distribution detection.
The device employs a rectangular array of detection rods and position sensors. A lifting mechanism drives the detection rods to contact the surface of the prepreg, recording the displacement height of each detection rod in real time. This data is then converted into electrical signals by the position sensors to output height difference data, enabling comprehensive and accurate thickness detection.
It achieves comprehensive and high-precision measurement of prepreg thickness, eliminates optical errors, and improves measurement speed and data accuracy.
