The roller structure comprises a lower roller and an upper press roller; the rotary cylinder is used for rotating the upper base to change or fix the relative position of the upper base and the roller structure. The device has a simplified structure. The device and method are suitable for applying a film to 3D glass with two opposite curved edges due to convenient operations, high film-applying precision and efficiency.

An apparatus including an overlay with a top side and a bottom side. The apparatus also can include an adhesive component with a top side and a bottom side. The top side of the adhesive component can be adhered to the bottom side of the overlay. The adhesive component can be configured to adhere the bottom side of the overlay to a screen of an electronic device in a single-use application of the overlay by adhering the bottom side of the adhesive component to the screen of the electronic device. The apparatus can be configured such that, when the overlay is removed from being adhered to the screen of the electronic device after the single-use application of the overlay, at least a portion of the adhesive component is detached from at least a portion of the overlay. Other embodiments are provided.

A portable film application apparatus includes a base, a positioning seat, a film holder, a conveyor and a film detaching device, wherein a positioning station and a film sticking station are provided on two sides of the base, respectively. The positioning seat is disposed at an end of the positioning station to lock the position of an electronic device. The film holder is disposed at an end of the film sticking station to lock the position of a film. The conveyor slides the positioning seat alternately between the positioning station and the film sticking station to match the electronic device with a membrane. The film detaching device is disposed at an end of the film sticking station to separate a release layer from the membrane.

Methods and apparatus to form venting channels on a panel for a decorative layer are disclosed. An example method includes contacting an outer surface of a tool to an outer resin layer of a panel. The outer surface of the tool has protrusions. The example method includes moving the outer surface of the tool on the outer resin layer of the panel in a first direction to cause the protrusions of the tool to form first venting channels on the outer resin layer of the panel and coupling a decorative layer to the outer resin layer of the panel via an adhesive layer. The first venting channels are to vent at least one of gas or vapor away from the decorative layer to deter separation of a portion of the decorative layer from the outer resin layer.

The present invention discloses a packaging box of a covering film and a film applicator. By structural designs of the packaging box and the covering film, the packaging box is provided with an internal cavity matching an outer shape of an electronic device and the covering film includes a release film having an extension portion, enabling the packaging box to provide the covering film with storage, dustproof and shock-absorbing functions and to further serve as a film application auxiliary tool when a film application process is performed. Thus, a user is allowed to accurately, quickly and efficiently form a layer providing protection on a surface of the electronic device directly by using the packaging box.

According to one aspect of the present invention, an adhesive sheet material application device is disclosed, which includes a roller support bar, a roller support member, a first and second handle, and a roller. According to another aspect of the present invention, an adhesive sheet material application device is disclosed which includes a roller support member, a roller, and a second handle.

A mobile phone screen protector device includes a positioning seat, a positioning frame, an auxiliary adhesive sheet, a screen protector, and a scraper. The positioning seat has a first raised portion, a second raised portion, and a positioning space between the first and second raised portions for accommodating a mobile phone with a screen facing upward. The first raised portion is higher than the second raised portion. The auxiliary adhesive sheet is adhered to an underside of the positioning frame. The screen protector is adhered to an underside of the auxiliary adhesive sheet. The positioning frame and the auxiliary adhesive sheet are confined to the tops of the first and second raised portions, and the screen protector is inclined at an angle relative to the screen. The scraper is pressed to scrape against the auxiliary adhesive sheet for the screen protector to be adhered to the screen.

A screen protector installation machine uses a screen protector laminate to apply a screen protector to a cell phone. The laminate comprise a web that carries the screen protector and a backing layer. The laminate is carried by a lid coupled to a base and closable over the base. An impression in the base receives the cell phone. A first slider is carried by the lid and comprises a spool rotatable with respect to the lid. A tab of the backing layer is coupled to the spool. As the slider slides over the cell phone, the spool rotates to wind the backing layer around the spool to expose the screen protector. The lid properly positions and orients the screen protector over the mobile device. The lid is automatically lowered onto the base, and the screen protector is automatically lowered onto the mobile device, by movement of the first slider after the backing layer is removed.

The present application provides a screen protector and a method for applying a screen protector, including a release film, a hydrogel film, a silicone protective film, and a release liner sequentially stacked, an edge of the release film is provided with positioning lug, the silicone protective film is provided with a die-cutting line, an edge of the first part protrudes outwards to form a first lug, and an edge of the second part protrudes outwards to form a second lug. The silicone protective film is divided into two parts, tearing off the first part and tearing off the second part are independent from each other, avoiding the movement of the screen protector due to the large amplitude of the tearing film during the tearing process, the deviation occurring during the applying process of the screen protector is avoided, and the applying efficiency of the screen protector is improved.
