Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] figure 1 A schematic structural view of the main body of the adhesive film thermocompression forming device in a certain embodiment is shown. The film hot-press forming device includes a film carrier 1, a hot-press module 2, a vacuum box 3, a horizontal adjustment mechanism 5, a cylinder 4, and the like. The adhesive film carrier 1 is used to place and fix the adhesive film to be formed (such as OCA optical adhesive film), and provide a forming mold for the adhesive film. The adhesive film carrier 1 is installed on the vacuum box 3 . As an extension, the adhesive film carrier 1 can also be connected to other vacuuming equipment, but the preferred solution is to install it on the vacuum box 3, which can improve the uniformity and strength of the vacuum adsorption force, and avoid excessive or uneven adsorption force from causing glue. Membrane ...

Abstract

The invention discloses a hot press molding device for adhesive films, comprising an adhesive film carrier (1) and a hot press mold group (2), wherein the adhesive film carrier (1) comprises a carrier plate (11) and a lower heating plate (12), the carrier plate (11) is provided with a product profiling part (111), and a plurality of vacuum adsorbing through holes (1111) are formed in the surface of the product profiling part (111); the hot press mold group (2) comprises an upper press plate (21) and an upper heating plate (21), and the upper press plate (21) is provided with a concave part correspondingly matched with the product profiling part (111); and an adhesive film to be molded is vacuum adsorbed to the surface of the product profiling part (111) on the carrier plate (11), the upper heating plate (21) and lower heating plate (12) heat the adhesive film, and the hot press mold group (2) presses towards the adhesive film carrier (1) to mold the adhesive film. The hot press molding device for adhesive films can be applied to molding of OCA (Optical Clear Adhesive) optical adhesive films required by 3D curved glass or 3D curved screens.

Description

technical field [0001] The invention relates to the field of industrial automation, in particular to an adhesive film thermocompression forming device. Background technique [0002] Curved / curved surfaces have gradually become a hotspot in the design of mobile terminals, and the pasting of 3D curved glass in front of the screen is an important link in the production of mobile terminals with curved or curved surfaces. In the specific production process, it is necessary to paste OCA optical glue on the 3D curved glass first. Existing OCA optical adhesive parts are basically pure flat, on the one hand, they need to be cut to fit different sizes of glass; good fit. In order to improve the lamination effect of OCA optical glue for 3D curved glass, improve the degree of automation and production efficiency of processing, it is necessary to provide a solution for the molding of the film corresponding to OCA optical glue for 3D curved glass and the lamination on 3D curved glass. ...
