Semi-finished product production line suitable for float electronic display glass

Abstract

The invention discloses a semi-finished product production line suitable for float electronic display glass. The semi-finished product production line comprises an annealing kiln, a first broken platedetector is arranged at the downstream position in the pulling direction of the annealing kiln, an emergency transverse cutting machine is arranged at the downstream position in the pulling directionof the first broken plate detector, a breaking roller is arranged at the downstream position in the pulling direction of the emergency transverse cutting machine, and an emergency falling plate is arranged at the downstream position in the pulling direction of the breaking roller; according to the invention, the stress of the glass substrate can be detected online; glass scratches can be reduced;the online detection precision of the appearance size of the glass can be improved; the breakage rate of subsequent production, processing, packaging, transportation and client sheet taking caused byglass microcracks can be reduced; the glass sampling difficulty can be reduced, and the sampling safety is improved; the semi-finished product packaging device can be in seamless butt joint with a post-processing line while realizing semi-finished product packaging so that continuous production of glass from semi-finished products to finished products is realized, and the production efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of glass production lines, in particular to a semi-finished production line suitable for float electronic display glass. Background technique [0002] In the production process of float glass, a series of process links from raw materials to melting, forming, annealing, cutting, etc. are crucial to the quality and output of glass production. How to improve the output and quality of glass, in addition to the heat of the glass itself In addition to the fine control of the production process, the improvement of the cutting rate in the production of semi-finished glass and the control of glass waste are also critical and cannot be ignored; [0003] In the process of float glass production, the semi-finished product line is an intermediate process in the glass production process. It is responsible for the initial processing and quality inspection of the annealed glass substrate, and obtains the thickness and weigh...

AI Technical Summary

Problems solved by technology

[0004] Float electronic display glass mainly refers to liquid crystal glass used in flat panel display technology. This kind of glass requires no bubbles, stones and other defects that affect the optical quality of the glass. It not only has strict requirements on the surface characteristics of the glass during molding, but also The accuracy required for the outer dimensions of the substrate glass also reaches 1 / 10mm. In addition, cracks, dust, and scratches generated during the production of semi-finished products will also cause adverse effects on the subsequent grinding, cleaning, transportation, and customer use of the float electronic display glass. In severe cases, it will even lead to the batch abandonment of glass. Therefore, the traditional float glass semi-finished production line is difficult to meet the production requirements of float electronic display glass. In addition, float electronic display glass is ultra-thin glass and is produced by float method. The current electronic display glass is usually high-generation glass of more than 8 generations, and its size is relatively large. It is difficult to sample on the traditional float glass semi-finished production line, and the safety risk is relatively large. Therefore, the present invention proposes a method suitable for float electronic display glass Semi-finished product line to solve the problems existing in the existing technology
