The screen protection film can effectively resist scratches, stains and fingerprints and other intrusions on the screen with its excellent protection performance, plays a very key role in maintaining the screen in good condition and prolonging the service life of the screen, and is deeply favored by the majority of users.

[0003] With the increasing demand of users for the quality of screen protection film, traditional manual film pasting is difficult to accurately control the pasting process, which can easily lead to frequent problems such as bubbles and wrinkles, seriously affecting the screen clarity and operation fluency, and cannot meet the current needs. Under this background, various screen protection film pasting devices have emerged. These pasting devices rely on specific structural design to accurately position the screen product to be pasted and the protection film, ensuring accurate positioning of the two during pasting. When pasting, the innovative way of tearing off the release film reversely allows the adhesive surface of the protection film to be in close contact with the screen product to be pasted at the moment of contacting the air, greatly reducing the probability of dust adhesion. Subsequently, the protection film is rolled and pasted with the help of rollers, realizing dust-free rolling pasting operation. Compared with traditional manual film pasting, the quality and efficiency of film pasting are significantly improved, and the generation of defects such as bubbles and wrinkles is greatly reduced, providing users with a more high-quality and reliable film pasting experience.

[0004] However, the existing film pasting device has obvious shortcomings in the product taking-out process. At present, most film pasting devices use hand-dogging slot to take out the product, which has many disadvantages. On the one hand, during the product taking-out process, the fingers need to exert pressure on the side of the product, and once the operation is slightly deviated, it is extremely likely to pull the attached protection film along the side of the product, thereby causing damage to the edge of the protection film and affecting the integrity and use effect of the product. On the other hand, in order to realize high-precision pasting of the product and the protection film, the film pasting device and the product are tightly matched, resulting in that the product is firmly fixed on the film pasting device, and a large damping is generated between them, making it extremely difficult to take out the product by relying on the hand-dogging part alone, which brings many inconveniences to the user operation.
