Overlay Applicator Tray Alignment Mechanism

The patent introduces a cradle as an intermediary device between the overlay applicator and the electronic device. The cradle includes positioning features that engage with corresponding features on the electronic device, providing precise alignment. The applicator is designed to work in conjunction with the cradle, where the cradle holds the device steady and positions it correctly relative to the overlay, thereby achieving accurate alignment without requiring complex manual positioning operations.

The patent incorporates a wiper that performs preliminary cleaning of the screen surface before the overlay is applied. The wiper removes contaminants such as dust, fingerprints, and oil that would otherwise cause air bubbles and adhesion problems. By cleaning the surface in advance as part of the application process, the system ensures proper adhesion without requiring separate complex cleaning steps or tools.

The patent uses a wiper to perform preliminary cleaning of the screen surface before the overlay is applied. This preliminary action removes contaminants such as dust, fingerprints, and oil that would otherwise become trapped between the overlay and the screen. By cleaning the surface in advance, the system minimizes contamination exposure and ensures a clean bonding interface without requiring extended cleaning periods.

The patent designs the applicator system to perform multiple functions including cleaning, alignment, and overlay application in an integrated manner. The wiper cleans the screen as part of the same operation where the overlay is positioned and applied. This self-service approach allows the adhesive to remain protected under the release liner until the moment of application, while the system simultaneously prepares the surface and applies the overlay without requiring early removal of the liner that would expose the adhesive to contaminants.
