3D (three-dimensional) curved glass hot-pressing equipment

Abstract

The invention discloses 3D (three-dimensional) curved glass hot-pressing equipment. The equipment comprises a forming chamber, and a preheating device, a hot-pressing device and a cooling device, which are connected with the forming chamber and arranged in a pipelining manner. According to the 3D curved glass hot-pressing equipment, a single plain glass blank arranged in a mold sequentially passes through the preheating device, the hot-pressing device and the cooling device in the forming chamber, and is directly softened, pressed and cooled into a required shape under the action of each device, and compared with a cold machining manner, such a manner has the advantages that only a proper mold is required to be selected and corresponding heating, hot-pressing and cooling parameters are required to be regulated, so that not only is simplicity in operation ensured, but also a camber and a fillet which can be machined can be autonomously adjusted by virtue of the mold; the problem that the camber and the fillet which can be machined is limited when the cold machining manner is adopted for 3D curved glass in the prior art is solved.

Description

technical field [0001] The invention relates to the field of hot pressing equipment, in particular to a 3D curved glass hot pressing equipment. Background technique [0002] With the development of smartphones, in addition to Samsung and LG launching smartphones with curved screens, smartphones like Apple’s use more non-planar glass with rounded edges, that is, the middle area of ​​the glass is flat and the edges are flat. A curved surface is used for the transition, and the above-mentioned non-planar glasses all belong to the scope and application scope of the smart phone 3D curved glass of the present invention. [0003] Because the processing of 3D curved glass is difficult and the process route is relatively complicated, the existing non-flat glass generally adopts cold processing, that is, the edge of flat glass is ground and polished to obtain the required curved edge; however, The size of the arc fillet that can be processed by cold working is also limited.
