Description

[Technical Field]

[0001] The present invention relates to the technical field of electronic device components, and more particularly to a film application device. [Background technology]

[0002] Nowadays, electronic devices have become an indispensable communication tool in people's lives. However, due to their frequent use, the screens of electronic devices are easily soiled and even damaged. Therefore, the screens of electronic devices are generally protected with tempered films for electronic devices, which have self-adhesive properties. This self-adhesive property is mainly realized by the fact that after a portion of the tempered glass film is adhered to the screen of the electronic device, the adhesion area continuously expands outward by relying on its own gravity without the application of external force until the entire adhesion is achieved.

[0003] There are several film application devices on the market that can easily apply films, and they are equipped with a structure on which a reinforced film assembly can be fixed and positioned. When applying a film to an electronic device, the electronic device is placed in the film application device, and the reinforced film assembly is fixed to the positioning structure on the film application device, and then the reinforced film assembly is placed over the screen of the electronic device to align it with the electronic device, thereby attaching the reinforced film to the screen of the electronic device. This improves the accuracy of the film application. However, when installing the film application assembly, the operator often has to manually attach the reinforced film assembly to the film application device. This manual operation is complicated and the positioning film in the reinforced film assembly is likely to detach from the reinforced film, which will result in the loss of positioning function and the inability to align the reinforced film with the screen of the electronic device, resulting in failed film application.
