AI Technical Summary

Technical Problem

The existing surface flatness detection devices have shortcomings in detection accuracy and flexibility, and it is difficult to comprehensively evaluate the flatness of the surface, resulting in possible local unevenness or deformation without being discovered in time.

Method used

A surface flatness detection device based on four-point detection is designed, and a stroke adjustment mechanism and a detection assembly are used. The detection assembly drives its movement through a rotating drive shaft to adjust the detection position, and four sensors are arranged on the detection assembly to form a quadrilateral array to realize multi-point detection.

Benefits of technology

Through the multi-point detection structure, the flatness of the surface can be more comprehensively evaluated, the error caused by a single measurement point can be reduced, the accuracy and reliability of the inspection can be improved, and the product can meet strict quality standards.
