The present application belongs to the technical field of manufacture for protection film for a terminal curved surface, and relates to a protection film for a terminal curved surface and manufacture method thereof, the hardened layers is provided on both sides of the substrate layer, and the substrate layer and the two hardened layers form the original sheet. The original sheet is hot-pressed by a hot pressing device, and the upper mold and the lower mold clamping the original sheet are heated, pressurized and cooled in order to obtain a protection film for a terminal curved surface, and the mold core outer rounded corner combining with the mold cavity inner rounded corner are pressurized to form a curved surface portion. The hardened layers is disposed on both sides of the substrate layer, so that the stress on both sides of the substrate layer are cancel each other after the substrate layer is heated, and the terminal surface protective film is more flat. The protection film for a terminal curved surface is easy to be molded, sensitive to be touched, high in hardness, and the outer side hardness can reach 9H, which is not easy to produce scratches, anti-fingerprint, anti-fragmentation edge, explosion-proof, and the protection film for a terminal curved surface has a curved surface portion suitable for protecting the terminal curved screen.
A method for applying a screen protector to a cell phone screen protector is provided, including: providing a cell phone screen protector and a cell phone to be applied; cleaning a screen of the cell phone to be applied; tearing off the release liner by the label of the release liner, simultaneously lightening the screen of the cell phone to be applied, and sticking the silicone protective film on the screen, and uncovering the first part via the label of the first part; using a scraping card to scrape slightly from top to bottom; uncovering the second part via the label of the second part, and using the scraping card to scrape slightly from top to bottom; using the scraping card to scrape outwardly along a curved edge of the screen; tearing off the PET release film, and smoothing both sides of the screen.
A film gluing device for gluing a protective film (213) in a protective film assembly (200) to a display screen of an electronic device by means of a photocurable glue. The film gluing device comprises a base (111), a light source mounting structure (121) connected with the base (111) and a UV light source (122) mounted on the light source mounting structure (121) and configured to irradiate the photocurable glue; the base (111) includes an operation panel (112) used for accommodating the electronic device such that the display screen is exposed; the light emitted by the UV light source (122) irradiates the photocurable glue that covers the area where the protective film (213) overlays the electronic device, so as to adhere the protective film (213) to the display screen. The film gluing device can improve the efficiency in gluing a film on the display screen of the electronic device.
A 3D, fully-tempered glass membrane (100), comprising: cutting a piece of transparent glass, performing CNC processing so as to obtain a processed glass matching a cellphone screen, then polishing and tempering to obtain a piece of transparent, tempered glass (10). The transparent, tempered glass (10) comprises a back surface (12) and a front surface (11). The back surface (12) has a curved edge (121). A double-sided adhesive layer (20) is laminated on the back surface (12). A cut piece of transparent glass undergoes CNC processing, polishing, and tempering to obtain a transparent, tempered glass with high hardness and abrasion resistance. The back surface of the transparent, tempered glass has a curved edge configured to match a curved edge of a cellphone screen, allowing the transparent, tempered glass to completely cover the cellphone screen and preventing a watermarking issue from appearing at the edge of the transparent, tempered glass and at the edge of the cellphone screen. The invention does not use a colored band, and therefore does not block an edge of a display portion of the cellphone screen.
