AI Technical Summary
In existing technologies, measuring the displacement distance of a transducer requires contact with the object being measured, which makes the measurement process complex and poses a risk of damaging the transducer surface. Furthermore, two-dimensional instruments cannot fix the height during measurement.
Employing a multi-track guiding structure and a laser displacement sensor, the displacement of the transducer is measured non-contactly using laser. Combined with the first and second moving structures, the positions of the laser displacement sensor and the object being measured are adjusted in the horizontal and vertical directions to ensure that the laser is aligned with the transducer.
It achieves high-precision (0.01mm) non-contact measurement, avoids errors in the measurement process, improves detection efficiency and consistency, and reduces operational complexity and cost.
