Abstract

The invention relates to a concave surface attaching method, which is suitable for attaching a thin film to a concave surface of a base material, and is provided with a first jig and a second jig, the first jig is provided with a planar end part, the second jig is provided with a convex surface matched with the concave surface, a first pre-forming process is firstly carried out, the end part of the first jig is imprinted on the surface of the thin film, and a second pre-forming process is carried out. A second pre-forming process is carried out, the convex surface of a second jig is embossed on the concave part of the thin film, the concave part of the thin film is stretched to form a shape conforming to the concave surface, and finally, the concave part of the thin film is attached to the concave surface of the base material; according to the invention, two pre-forming processes are added before the laminating process, so that the total dependent variable at the center of the thin film can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of lamination, in particular to a concave lamination method that can disperse lamination strain. Background technique [0002] At present, the market trend of display panels is to develop products with non-planar and curved surfaces. The relevant supply chain has also begun to develop various molding technologies for 3D curved products. Lamination technology is a very important part of the display panel manufacturing process. How to Ensuring the product's bonding yield is also a bottleneck for many panel manufacturers to break through. [0003] In the lamination process of 3D curved products, concave lamination is usually the key, which directly affects lamination efficiency and lamination quality. Thermoforming is a molding method in which thermoplastic materials are heated to soften and processed with appropriate molds or jigs under pressure to make them into products. At present, when the film and the s...
