Application device for screen protector and application method thereof
An application device for a screen protector and an application method thereof are provided for applying an adhesive film to a screen of an electronic device with ease and precision. The application device is formed as a frame-like structure having an internal hollow region. The screen protector includes, from top to bottom, a protective layer, an adhesive film layer, and a release layer sequentially bonded together. The protective layer is greater in area than the adhesive film layer or the release layer and has a peripheral portion extending outwardly beyond the adhesive film layer or the release layer. The peripheral portion of the protective layer is attached to a frame-shaped top surface of the application device while the adhesive film layer and the release layer bonded thereto are placed in, and lie adjacent to a top portion of, the internal hollow region of the application device.
1. An application device for a screen protector comprising:
a frame-like structure with an internal hollow region and having a top portion and a bottom, wherein the hollow region is configured to conform a corresponding electronic device from the bottom; and
the screen protector, from bottom to top, comprising
a release layer being placed inside the hollow region, and being configured to be peeled before installing the screen protector to the electronic device;
a adhesive film layer being bonded to the release layer, being placed inside the hollow region, and being configured to attach to an application surface of the electronic device; and
a protective layer being bonded to the adhesive film layer, being attached on the top portion of the frame-like structure, and being configured to be detached from the frame-like structure by peeling off from the adhesive film layer on the application device or on the electronic device.
2. The application device as claimed in claim 1 , wherein the the protective layer has peripheral portion extended outwardly beyond the release layer and the adhesive film layer, and the peripheral portion is attached to the top portion of the frame-like structure.
3. The application device of claim 1 , wherein the release layer has a lateral side provided with a tongue.
4. The application device of claim 3 , wherein the tongue is integrally formed with the release layer.
5. The application device of claim 3 , wherein the tongue is externally affixed to an upper surface of an extension portion on the lateral side of the release layer.
6. The application device of claim 3 , wherein the tongue is affixed to a bottom side of the release layer.
7. The application device of claim 3 , wherein the internal hollow region of the application device has a side formed with a notch corresponding in position to the tongue of the release layer, and the tongue of the release layer extends out through the notch.
8. A method for applying a screen protector to an electronic device, comprising steps of:
providing the screen protector to an application device, wherein the application device being a frame-like structure having an internal hollow region, and the screen protector is initially formed with, from bottom to top, a release layer, the adhesive film layer and a protective layer, the release layer and the adhesive film layer are placed inside the hollow region, and the protective layer is attached on a top portion of the application device;
peeling off the release layer of the screen protector, wherein
mounting the internal hollow region of the application device downward on an outer frame of the electronic device to which the screen protector is to be applied;
contacting the adhesive film layer of the screen protector with an intended application surface of the electronic device; and
peeling off the protective layer from the adhesive film layer.
9. The method as claimed in claim 8 , further comprising:
moving the application device forcibly downward to separate the protective layer before peeling off the protective layer from the adhesive film layer.
