Glass hot bending forming device and method

Abstract

The invention discloses a glass hot bending forming device and method. The device comprises a conveying mechanism, a feeding and discharging mechanism, a preheating mechanism, a forming mechanism and a cooling mechanism, the conveying mechanism comprises a production conveying module and a backflow conveying module, and the production conveying module sequentially penetrates through the preheating mechanism, the forming mechanism and the cooling mechanism; and the backflow conveying module is used for conveying glass finished products in the mold to the feeding and discharging mechanism in a backflow mode for material taking operation, the production conveying module comprises a first conveying frame, the backflow conveying module comprises a second conveying frame, and the first conveying frame and the second conveying frame are each provided with a plurality of first rollers at intervals. A to-be-processed glass blank is transferred into the mold through the feeding and discharging mechanism, so that the mold is respectively transferred to the preheating mechanism, the forming mechanism and the cooling mechanism under the driving of the conveying mechanism to be processed to prepare a glass finished product, and then the glass finished product in the mold is returned and conveyed to the feeding and discharging mechanism for material taking operation; therefore, whole-course automatic operation is achieved, and machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of glass hot bending processing, in particular to a glass hot bending forming device and method. Background technique [0002] 3D curved glass has the characteristics of light and thin, transparent and clean, anti-fingerprint, anti-glare, and good weather resistance. Therefore, large-size, multi-touch 3D curved glass vehicle-mounted displays have become the mainstream development trend of the vehicle-mounted display market. At the same time, with the comprehensive popularization of OLED technology, LED flexible display has gradually become one of the important technologies of vehicle display. Furthermore, large-size 3D glass has broken through its application in curved screen mobile phones and wearable devices, and is facing a broader application prospect of vehicle display components. [0003] At present, most of the traditional hot bending technology is a hot bending forming device for small glass, such a...

Problems solved by technology

[0004] However, with the development of society, the central control glass of automobiles is getting bigger and bigger, especially for the current new energy vehicles, how to improve the efficiency of hot bending of glass is also an urgent problem to be solved; The direction is greater than 1.5 meters), the designed curved surface is complex, and when the angle is large, it is difficult to achieve high-quality molding with a single type of heating method. The heating method of the traditional large-scale glass bending machine is a single heating method of heat transfer. Cause problems such as uneven heating of products, low processing efficiency, low yield rate of finished products and long production cycle
