A device for sticking a film on a display screen of a mobile device, the device including: a film holder for sticking a film main body on the display screen, the film holder having a protruding engagement piece which is inserted into and fixed to a connector on the side of the mobile device which serves as an engagement partner and a positioning means for the film main body, the film holder has at least two positioning projections and the film main body has the same number of positioning holes which are commensurate with the positioning projections.

A screen film applicator includes a seat, a positioning member, and a first mechanism, the latter two of which are disposed on the seat. The seat has a track and a positioning portion arranged beside the track. The positioning member is movable with respect to the positioning portion for clamping a communication device. The first mechanism includes a top fixing member disposed on the seat, a moving carriage movable along the track, a bottom fixing member synchronously movable with the moving carriage, and a roller movable with the moving carriage. The top and the bottom fixing members are configured to respectively fix a top releasing film and a bottom releasing film respectively adhered on two opposite sides of a soft screen film. When the moving carriage is moved away from the top fixing member, the roller can gradually press the soft screen film onto the communication device.

A tool for applying tint film to the rear window of an automobile has a unitary body with a concave top side and a convex bottom side, and the unitary body including a first elongate wing with front and rear edges extending to a first distal end, and an opposite second elongate wing with front and rear edges extending to a second distal end, and a central portion between the first and second elongate wings. The unitary body includes a skeletal frame member and flexible blades fitted to the skeletal frame member and extending about a periphery of the first and second elongate wings to define the front and rear edges and distal ends. The skeletal frame maintains desired curvature and prevents excessive flexing and bending of the elongate wings. The first and second wings have different degrees of curvature measured transversely between the respective front and rear edges.

Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.

The present Invention discloses two robot assisted automated methods for application of decals on complex 3 dimensional surfaces without wrinkle and bubble. The method includes loading of objects having 3D surfaces on an object holding fixture manually from a conveyor belt, picking up a first application fixture automatically by a robot, peeling off the liner disposed on the decal manually and placing the decal on the first application fixture which holds the decal by suction, positioning the decal with exposed adhesive accurately on a first 3D surface of the object and switching off the suction automatically leaving the decal placed on the 3D surface of the object, placing the first application fixture back and picking up a second application fixture automatically by the robot for squeegee application, applying the second application fixture to complete the squeegee application by pressurizing the decal. The first application fixture is configured to be programmed to hold decals of different shape and size and the second application fixture is configured to be programmed to identify the 3D direction of squeezing pad motion within each region of such decals to eliminate the bubbles without wrinkling. The second method uses a mechatronic pick and place mechanism for picking up a decal from the decal stack and placing of the decal on the 3D surface of the object automatically.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a roller apparatus may be used to apply the protective film on the surface of the electronic device. The roller apparatus may include an opening for receiving a display peg.

A system for protecting a surface of a substrate includes a protective film, which is configured to be applied and secured to the surface, as well as a backing on an adherent surface of the protective film and an application tape over an exterior surface of the protective film. Protruding features, such as tabs, adjacent to different peripheral edges of the protective film may enable removal of the backing and the application tape from the protective film, and may include features that indicate the order in which each protruding feature is to be grasped to peel its corresponding element away from the protective film. Methods of using such a system are also disclosed.
