AI Technical Summary
In existing technologies, it is difficult to accurately locate the center of the screen when applying screen protectors to electronic products, resulting in poor adhesion and affecting the user's normal use and experience.
A single-use film application structure was designed, including an inner tray and a film application component. The inner tray has a receiving groove and a clearance groove. The film application component is fixed in the receiving groove by double-sided adhesive. Combined with ultrasonic high-frequency vibration welding and PET material vacuum forming, the accurate positioning and fixation of the film application component are ensured.
It achieves accuracy and convenience in the film application process, improves user experience, avoids movement and misalignment of the film application components, and uses environmentally friendly materials, has high molding efficiency, and high joint strength.
