Abstract

The invention discloses a preparation method of OCA optical glue with a round hole and a light-shielding black edge, which comprises the following steps: Step 1, laminating the OCA tape and a carrier tape; Step 2, die-cutting, discharging waste and laminating the light-shielding tape; Step 3: Die-cutting and waste discharge of OCA optical glue products; Step 4: Fool-proof inspection; Step 5: Round hole waste removal and round hole cross-hole exhaust; Step 6: Final lamination and slicing out. The invention also discloses a die-cutting device of the OCA optical glue with a round hole and a light-shielding black border. The OCA optical glue with the black edge of the round hole prepared by the present invention solves the problem of light leakage at the edge of the polarizer through hole in electronic products with a camera under the screen; at the same time, the preparation method improves the yield and production of the OCA optical glue efficiency.

Description

technical field [0001] The invention relates to the technical field of optical glue production technology, in particular to a method for preparing an OCA optical glue with a round hole and a shading black border and a die-cutting device for preparing the OCA optical glue. Background technique [0002] OCA optical adhesive is one of the raw materials for important touch screens. It is obtained by making optical acrylic adhesive without base material, and then laminating a layer of release film on the upper and lower base layers. It is a double-sided lamination without base material. adhesive tape. OCA optical glue is the best adhesive for touch screens. Its main uses are: lamination on electronic paper, transparent device bonding, projection screen assembly, aerospace or military optical device assembly, display assembly, lens assembly, resistive touch screen G +F+F, F+F, capacitive touch screen, panel, ICON and plastic materials such as glass and polycarbonate are special a...
