Ultrathin electronic glass forming device and forming method

Abstract

The invention discloses an ultrathin electronic glass forming device and a forming method. The ultrathin electronic glass forming device comprises a forming slot, a forming medium feeding system, a detection control device, a heating device and a forming edge roller, wherein the forming slot is divided into a high-temperature forming section and a low-temperature forming section in turn along the length direction of the forming slot and the running direction of the glass liquid; to-be-formed glass liquid is placed above the forming slot; a pothook is arranged at the upper part in the forming slot; a two-layer forming medium mixer is fixed and locked on the pothook; a plurality of purging devices and a water draining valve are arranged at the bottom in the forming slot; and vent valves used for releasing pressure are arranged on the two sides of the forming slot. The forming device and the forming method can be used for achieving the following objectives: (1) the thickness of the electronic glass after once forming is below 0.5mm; (2) the electronic glass can meet various stipulations in national standards and can meet the subsequent processing use requirements; and (3) the forming process is nontoxic and pollution-free, and meanwhile, the forming medium is low in cost.

Description

technical field [0001] The invention relates to the technical field of ultra-thin electronic glass, in particular to an ultra-thin electronic glass forming equipment and a forming method. Background technique [0002] Ultra-thin electronic glass refers to electronic glass with a thickness in the range of 0.1-1.1mm.

AI Technical Summary

Problems solved by technology

When forming glass by the float method, due to the existence of metal tin, the lower surface of the glass is easily stained with tin, which requires secondary treatment such as grinding and polishing, and the post-processing cost is high, so that the performance of ultra-thin electronic glass products produced by the float method cannot reach the high-end generation Liquid crystal substrate glass requirements, and heating metal tin requires high energy consumption
