AI Technical Summary

Technical Problem

Existing curved screens are prone to deformation after processing due to sudden temperature changes or impacts.

Method used

A deformation-resistant fixture for hot bending of curved screens was designed, comprising a fixture box, a fixture structure, and a retaining structure. The fixture box is equipped with vertically parallel clamping plates and a pressing mechanism. Deformation is prevented by pressing and limiting the structure. The surface of the clamping plates is provided with a curved structure to conform to the shape of the screen. The pressing mechanism and a long compression spring are used to prevent loosening.

Benefits of technology

It effectively prevents curved screens from deforming under temperature changes or impacts, maintaining shape stability and avoiding product crushing.
