AI Technical Summary

Technical Problem

Existing technologies are difficult to use efficiently and accurately to measure the offset and deflection angle of glass substrates. Manual measurement is inefficient and inaccurate, and can easily scratch the glass surface. Furthermore, existing mechanisms are not compatible with the support structure of horizontal frame packaging, resulting in insufficient installation stability.

Method used

A measuring device including a positioning frame, calipers, angle gauges, probes, and probes was designed. Through the cooperation of the positioning plate and the handle, it is adapted to the support structure of the horizontal frame packaging. The stability is improved by using secondary bolts and buffer layers, and the calipers and probes reduce the risk of scratches, so as to achieve fast and accurate measurement of offset and deflection angle.

Benefits of technology

It improves the detection efficiency and accuracy of glass substrate offset and deflection angle, reduces the probability of glass surface scratches, enhances measurement flexibility and coverage, and improves device stability.
