Abstract

The utility model discloses a mobile phone film sticking auxiliary device, which relates to the technical field of film sticking devices. Through the coordinated arrangement of a suction air pump, a bearing frame, a scissor frame and an air bag, the suction air pump is used to inflate the air bag, and the expansion of the air bag causes an extrusion block to slide outward to open the scissor frame, so that four clamping columns on the scissor frame move synchronously to clamp a mobile phone, which plays a correction and positioning role for the mobile phone, and is convenient for sticking a UV film on the mobile phone screen. Through the coordinated action of the suction air pump, a clamping block, a clamping frame and an elastic vacuum bag, the clamping frame slides toward the clamping block with the elastic vacuum bag on the outer side of the mobile phone. After the clamping frame is clamped on the outer side of the clamping block, the suction air pump is used to absorb the air inside the elastic vacuum bag, so that the UV film is stuck on the mobile phone screen, and then UV irradiation is performed until the UV film is hardened, thereby improving the sticking efficiency. Moreover, because the elastic vacuum bag has stretchability, after vacuuming, the sticking of the edge of the curved screen is more complete, and the bubble rate of scraping the screen with a scraper after manual sticking is reduced.

Technical Field

The utility model relates to the technical field of film sticking devices, and in particular to a mobile phone film sticking auxiliary device.

Background Art

In order to prevent the mobile phone screen or other surfaces from being scratched during use, it is usually necessary to stick a layer of protective film on the mobile phone screen. Mobile phone protective film, as a protective medium to protect the mobile phone screen, is widely used in mobile phone screens.

The existing film pasting method generally involves manual film pasting. After manual pasting, a scraper is generally used to scrape the screen to remove bubbles between the protective film and the screen. However, in the process of using a scraper to scrape the screen, it is easy to cause problems such as misalignment between the protective film and the screen, damage to the protective film, and poor film pasting effect. The film pasting efficiency is low, especially for curved screens, which have poor adhesion to the protective film. Therefore, a mobile phone film pasting auxiliary device is proposed to improve the above problems.
