Description

This invention relates to the technical field of attaching films to mobile phones, and more specifically to a general-purpose dust-free film attachment device for mobile phones.

Nowadays, mobile phones have become an indispensable electronic product in people's lives. Especially since the emergence of smartphones, people's lifestyles have changed dramatically. With the development of smartphones, mobile phone screens have become larger and thinner. This situation directly makes mobile phone screens more susceptible to cuts and cracks during use, which affects the display effect and appearance of the screen. In daily use of mobile phones, mobile phones generally have a protective film attached to the screen, which can protect the screen and not affect the appearance and use of the mobile phone. Due to the wide range of applications of mobile phone films, basically all smartphones, especially those with large screens, are attached with a protective film.

However, the application of a film on a mobile phone usually requires the use of a dedicated film application tool. At present, there are mainly two types of dedicated film application tools: one is a commercial film application device, and the other is a general user's film application device. Commercial application devices are generally used by mobile phone manufacturers, which are huge in volume, complex in structure and expensive, and general users' film application devices are often used in a single size, which are both disposable and waste resources. Moreover, the operation of the film application method is diverse and the user's usage method is very challenging, and it is necessary to rely on a certain film application technology to complete the film application work, otherwise it is difficult to apply once, and when the repositioning is released, it will attract dust or other problems will occur, leading to the disposal of the film. The only opportunity to apply the film is disposable, and the failure to apply the film will increase the cost of applying the film.

The deficiencies and shortcomings of existing commercial film pasting devices are their large volume, complex structure, complicated operation procedures, overall weight, and at the same time, their very high price, which makes it difficult for general film pasting businesses to bear the cost burden, and they cannot be universally applied to more new model sizes of mobile phones at present. Existing film pasting devices for general users are dedicated to a single size, can only be used with one model size of mobile phones, and cannot change the mobile phone model, that is, after the model size of the mobile phone changes, the mobile phone film pasting device needs to be replaced, and general users do not use it much, which further tests the skills of the film pasting device, which causes inconvenience to users in using the mobile phone film pasting device and affects the user experience.
