Description

A processing platform for mobile terminal curved glass forming

technical field

The utility model relates to the technical field of hot pressing equipment, in particular to a processing platform for forming curved glass of a mobile terminal.

Background technique

With the development of mobile terminals (smartphones, tablet computers, etc.), in addition to Samsung and LG launching smartphones with curved screens, smartphones like Apple’s use more non-flat glass with rounded edges, that is, glass The middle area is plane and the edges are transitioned by curved surfaces. The above-mentioned non-planar glasses all belong to the related and used category of the smart phone 3D curved glass of the present invention.

The existing technology is used to process curved glass products. The preheating upper heating plate that constitutes the preheating mechanism is preheated without contacting the mold, so that the heat conduction efficiency is very low, and the mold cannot be quickly raised to the required preheating temperature. After being heated to a high temperature by the forming mechanism, the formed mold is sent to the cooling line for cooling, which makes the glass with a curved surface formed by the sharp change of temperature frequently breakage, and also prolongs the overall forming time period of the curved glass .

During the preheating process, due to the effect of air pressure, the mold used to process the curved glass may be suspended in the forming chamber, which may cause the single piece of flat glass blank placed in the mold to separate from the mold or have a gap, resulting in If the molding is not complete, it is impossible to produce curved glass with arc chamfering, which reduces the yield rate.

In addition, because the processing of 3D curved glass is difficult, the process route is relatively complicated, and the forming pressure is difficult to control, the existing non-flat glass generally adopts cold processing, that is, the edge of the flat glass is ground and polished to obtain the required The arc edge; however, this cold processing method is easy to leave small cracks on the non-planar glass, which greatly reduces the yield of non-planar glass; moreover, the arc fillet size that can be processed by the cold processing method is also limited.

In the traditional glass product processing process, the processing platform is single, the number is limited, the processing efficiency is low, and high-quality curved glass cannot be obtained quickly.

Therefore, the prior art still needs to be improved and developed.
