Description

[Technical Field]

[0001] The present invention relates to the technical field of film attaching devices for mobile phones, and more particularly to a top cover pressing film attaching device. [Background technology]

[0002] With the advent of the network era, electronic devices have become increasingly indispensable tools in our lives. However, the screens of electronic devices are sometimes too fragile and are easily scratched or broken, which affects the display performance and aesthetics of the electronic device. Replacing the screen requires a lot of time and money. Therefore, people usually apply protective films to the screens of their mobile phones to protect them. Conventional film application devices first peel off the release film inside the protective film, then position the protective film and finally apply it to the screen of the mobile device. After the inner release film is torn off, a positioning operation is performed, and the film is then applied after positioning. This results in an inconsistent film application process, which takes a certain amount of time. Furthermore, the bonding surface of the protective film is exposed to air for a long time during the positioning process, making it easy for dust to adhere to it and resulting in poor application of the protective film. Furthermore, conventional film application assistant devices and film application methods do not have the function of cleaning the screen of the electronic device. Instead, additional dust removal tools such as wiping tissue paper are required to clean the screen of the electronic device. After the screen is cleaned, further film application processes can be performed. This results in an inconsistent film application process and is prone to introducing excessive external impurities.

[0024] The two sets of first side walls 25 have a first protruding sheet 101, a second protruding sheet 102, a third protruding sheet 103, a fifth protruding sheet 105, a sixth protruding sheet 106 and a seventh protruding sheet 107 formed on the side walls thereof, the first protruding sheet 101 has a first supporting edge 91, the second protruding sheet 102 has a second supporting edge 912, the fifth protruding sheet 105 and the fourth protruding sheet 104 both have a third supporting edge 913, the sixth protruding sheet 106 has a fourth supporting edge 914, the bottom of the third protruding sheet 103 corresponds to the first pressure boss 16, and the bottom of the seventh protruding sheet 107 corresponds to the second pressure boss 22.

[0025] In a preferred embodiment of the present invention, a first bar-shaped member is provided on the top of the release film layer, and a second bar-shaped member is provided on the top of the pull-out bar, and the first bar-shaped member is fixedly connected to the second bar-shaped member. Specifically, the first protruding sheet 101, the second protruding sheet 102, the third protruding sheet 103, the fourth protruding sheet 104, the fifth protruding sheet 105, the sixth protruding sheet 106, the seventh protruding sheet 107, the eighth protruding sheet 108, the ninth protruding sheet 109, and the tenth protruding sheet 1091 have a positioning effect on the side wall of the mobile phone to align the mobile phone with the glass film 3, and the first supporting edge 91, the second supporting edge 912, the third supporting edge 913, the fourth supporting edge 914, and the fifth supporting edge 915 have a positioning effect on the edge of the mobile phone screen to align the mobile phone screen with the glass film 3.

[0026] A first bar-shaped body 41 is provided on the top of the release film layer 4, and a second bar-shaped body 51 is provided on the top of the pull-out bar 5, with the first bar-shaped body 41 fixedly connected to the second bar-shaped body 51.

[0027] The working principle of the present invention is that the positioning surface 2, the glass film 3, the release film layer 4 and the pull-out bar 5 are bonded together.

[0028] This product's design utilizes the practical concept of "two points, one bar" for its film application design, i.e., "two positioning locking points, one film application bar." A positioning button is designed on the top of the film application device base, and the positioning hole on the positioning surface engages with the laminator positioning button to fix the top of the positioning surface. Two support and positioning locking points are designed on the left and right sides of the bottom of the film application device base. There are no fixed points on the top and bottom of the positioning surface, leaving the top and bottom of the bottom of the glass film in free movement space. Its function is to easily attach the bottom of the film to the mobile phone screen during application, eliminating the cumbersome manual sliding operation procedure that occurs with existing film application devices, where the glass film cannot be separated from the positioning surface. The central film application method is achieved by the two positioning locking points on the left and right sides of the bottom of the film application device.

[0029] The pull-out end is pulled out, and the second bar-shaped body of the pull-out bar is released from the release film layer. A pressure boss with a height of 2.5 mm is designed on each side of the bottom of the film application device, the role of which is to prevent the film application device and the mobile phone screen from being pressed too hard when the film application device is used to cover the screen of the mobile phone, so that the tape cannot be pulled out or cannot be pulled out at all. Existing film application devices on the market have the risk of the tape being difficult to pull out or the tape not being able to be pulled out, and to solve this problem, the film application device is designed with a boss height of 2.5 mm.

[0030] A film pasting bar is designed at the bottom of the film pasting device. The height of the film pasting bar is 3.0 mm, and the height difference between it and the bosses on both sides of the film pasting device is 0.5 mm. Its function is to paste the film in accordance with the left and right side support positioning locking points at the bottom of the film pasting device. Under the cooperation of "two points - one bar", when the film pasting device rises to the screen cover of the mobile phone, the film pasting device uses the central support of the positioning points on both sides, and the film pasting bar uses the height difference with the pressure boss to automatically contact the steel film and press it to the bottom of the mobile phone screen, so that the steel film is exhausted from the bottom to the top of the mobile phone, automatically completing the film pasting.

[0031] While embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
