At the same time, it usually has high hardness and scratch resistance, and can better resist scratches and wear in daily use.

[0003] Before the optical glass screen is hot-bending, it needs to be transported to the hot-bending device by special loading equipment. During the transportation process, dust and impurities in the external environment are easy to adhere to the optical glass, and the existing loading equipment does not efficiently clean the dust and impurities on the surface of the optical glass, which is easy to affect the transparency and hot-bending effect of the optical glass; at the same time, the existing loading equipment does not preheat the optical glass, which causes internal stress due to excessive temperature gradient, causing cracks or deformation in the optical glass during the hot-bending process.

At this time, the output end of the hot air tooling is close to the top of the optical glass to preheat its top. In this process, the two transmission wheels provide a flipping thrust to the two L-shaped frames, so that the two electric heating plates preheat the bottom of the optical glass. The above process preheats the top and bottom of the optical glass at the same time, so that the temperature distribution on its surface is more uniform, reducing the internal stress caused by excessive temperature gradient, and preventing the optical glass from cracking or deforming during hot bending.

At this time, the output end of the first nozzle faces the end of the optical glass. The clean water that rushes out will push the optical glass to move on several transmission rollers, and cooperate with the end of the feed plate to limit it to prevent it from moving excessively. Then the extended end of the lifting cylinder is controlled to extend to the longest. At this time, the optical glass is located below the output end of the first nozzle, which is convenient for the clean water that rushes out to clean its top. The extended end of the lifting cylinder is controlled to shrink and reset to the normal length, and the clean water sprayed from several nozzles continues to rinse the bottom of the optical glass. At this time, the position of the optical glass has moved, so that the clean water that passes through several transmission rollers can comprehensively clean the bottom of the optical glass, thereby ensuring the cleaning efficiency and avoiding affecting the transparency and hot bending effect of the optical glass.
