Full-automatic film coating assembly line for 3D curved glass and film coating method of full-automatic film coating assembly line

Abstract

The invention discloses a full-automatic film coating assembly line for 3D curved glass and a film coating method of the full-automatic film coating assembly line. The full-automatic film coating assembly line comprises a concave face synchronous transfer assembly, a convex face synchronous transfer assembly in butt joint with the concave face synchronous transfer assembly, a concave face film coating device and a convex face film coating device. The concave face film coating device and the convex face film coating device are arranged beside the concave face synchronous transfer assembly and the convex face synchronous transfer assembly correspondingly. The full-automatic film coating assembly line is high in automation rate, a concave face film coating procedure and a convex face film coating procedure are integrated on one assembly to be carried out, the circulating cycle of the 3D curved glass is saved, surface contamination and scratches caused in the transferring and circulating process to the 3D curved glass are avoided, and the film coating efficiency and film coating quality are greatly improved. In addition, the film coating automation rate is increased, meanwhile, a filmsuction plate and a film press roll can be prevented from interference during film coating, a protection film is pasted more fully, the film coating efficiency and film coating quality are further improved, and wide market application prospects are achieved.

Description

technical field [0001] The invention relates to the field of 3D curved glass, in particular to a fully automatic coating line for 3D curved glass and a coating method thereof. Background technique [0002] The glass cover plates used on the displays of smart terminal products in the existing market can be divided into: 2D glass, 2.5D glass and 3D curved glass. Among them, 2D glass is ordinary pure flat glass without any curved design; 2.5D glass is The middle is a flat design, and the edge adopts a curved design; the 3D curved glass can be designed as a curved arc in the middle and the edge. 3D curved glass is mainly bent by a hot bending machine, which can achieve a higher bending arc. Some physical properties of 3D curved glass are obviously better than 2D and 2.5D glass. 3D curved glass has the advantages of being light and thin, transparent and clean, anti-fingerprint, anti-glare, hard, scratch-resistant, and good weather resistance. Better display and touch experience...

Problems solved by technology

[0004] In the existing 3D curved glass coating production line, there are several problems as follows: First, the degree of automation is low, and there are many steps that require manual assistance, which leads to low efficiency of coating, and the workpiece is in the process of loading, coating, and unloading. It is easy to be polluted and damaged during the transfer process; secondly, the common processing method in the market is to divide the concave surface coating step and the convex surface coating step into two lines for operation, which leads to low docking and coordination between the two lines. As a result, the coating efficiency is low, and even a downtime accident occurs, which directly affects the coating efficiency and coating quality of the 3D glass; thirdly, the fixation of the 3D curved glass is unstable, causing the 3D curved glass to occur around the front and back during the coating process. The movement phenomenon causes more pores on the protective film and glass surface after coating, which affects the quality of the coating; in addition, the lack of support for the concave and convex surfaces of the 3D curved glass will cause the 3D curved glass to be damaged during the coating process. If a burst occurs, another surface will cause deformation or scratches on the convex surface of the 3D curved glass; again, the supply of protective film is low in automation and requires many steps of manual assistance, and the protective film cannot be supplied efficiently, nor can the release paper Recycling, which leads to the low efficiency of the film coating of the concave mold; thirdly, because the concave surface of the 3D curved glass is sunken downwards to a certain depth, and the convex surface is raised upwards to a certain height, which makes the cooperation between the suction film plate and the film pressing assembly easy to cause Mutual interference, resulting in insufficient pressing of the protective film by the pressing film component, resulting in poor quality of the coating, and air bubbles are likely to exist between the protective film and the 3D curved glass, resulting in the protective film falling off easily and failing to protect the 3D curved glass Effect
