Laminated glass processing device and method

Abstract

The invention provides a laminated glass processing device and method. The laminated glass processing device comprises a conveying mechanism, a drilling chamber, a drilling machine, a high-pressure heating chamber, a pressing roller set and a bubble breakdown mechanism, the pressing roller set comprises a first pressing roller, a second pressing roller and a first driving mechanism, and the bubble breakdown mechanism comprises a positive electrode plate, a negative electrode column and a lifting mechanism. After one corner of laminated glass is drilled by the drilling chamber, the drilled laminated glass is conveyed into the high-pressure heating chamber by the conveying mechanism, the laminated glass is sequentially pre-pressed in the vertical direction by the first pressing roller and the second pressing roller, so that uneliminated bubbles generated by water vapor in a PVB film are gathered to an opening hole, and then the negative electrode and the positive electrode plate are descended, wherein the negative electrode column descends into an open hole, the positive electrode plate descends to the outer side of the open hole, and a strong electric field formed by the negative electrode column and the positive electrode plate can enable bubbles around the open hole to be broken down and broken, so that the bubbles are dissolved in an adhesive film, and a finished product quality of laminated glass is ensured.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a processing device and method for laminated glass. Background technique [0002] Laminated glass refers to a composite glass in which one or more layers of organic polymer interlayer film is sandwiched between at least two layers of glass. After high temperature and high pressure treatment, the glass and the interlayer film are permanently bonded together. , Broken glass will stick to the interlayer film to prevent glass fragments from splashing, effectively preventing fragments from being stabbed and penetrating and falling accidents, and ensuring personal safety. It is often used in vehicles and other vehicles, high-rise building doors and windows, glass curtain walls, sightseeing elevators, etc. . [0003] The preparation methods of laminated glass include PVB film hot pressing method (dry method) and grouting method (wet method). When the dry method is used to prep...

AI Technical Summary

Problems solved by technology

[0003] The preparation methods of laminated glass include PVB film hot pressing method (dry method) and grouting method (wet method). When the dry method is used to prepare laminated glass, the glass plates will be rolled during the lamination stage to evaporate the water in the PVB film. The generated bubbles burst and dissolve, but under the pressure of the pressure roller, the moisture is easy to accumulate to the tail, which is difficult or impossible to remove, resulting in degumming of the glass after high pressure and the generation of bubbles, which should affect the quality of the finished laminated glass
