[0002] With the increasing use of smart devices, screen protection has become crucial. The primary method for screen protection is applying tempered glass screen protectors. To facilitate this process, the market offers screen protector application devices manufactured using vacuum forming or injection molding. These integrated vacuum screen protector applicators first place the tempered glass screen protector, then place the device's screen and screen protector face-to-face into the applicator, and finally remove the protective film from the tempered glass screen protector. However, traditional applicators cannot quickly remove all air bubbles between the screen protector and the screen, requiring a secondary treatment after application. This secondary treatment may damage the tempered glass screen protector or affect the application result. Utility Model Content

[0003] The purpose of this invention is to provide a screen protector applicator with a rapid air venting structure, which solves the technical problems of existing screen protectors being unable to quickly expel gas during application, resulting in numerous air bubbles, poor adhesion, and the need for complex secondary air bubble removal operations with existing applicators.

[0004] To solve the above technical problems, this utility model discloses a film applicator with a rapid venting structure, including a positioning frame and a supporting device. The positioning frame is adapted to the size of the device to be applicated for accurate fixation of the device.

[0014] Compared with the prior art, the beneficial effects obtained by this utility model are:

[0015] This utility model discloses a screen protector applicator with a rapid venting structure, including a positioning frame and a support device. The positioning frame is adapted to the size of the device to be covered for accurate device fixation. The positioning frame is arranged around the periphery of the support device, and its height is higher than that of the support device. An auxiliary venting structure, which is a raised strip higher than the support device, is provided in the middle of the support device. Utilizing the support of the raised strip for the middle part of the tempered glass screen protector, the middle part of the screen protector makes contact with the device screen first. Based on the principle of electrostatic adsorption, the air on the bonding surface is quickly and maximally vented. This solves the technical problems of existing screen protectors, which cannot quickly vent air during application, resulting in many air bubbles, poor bonding effect, and the need for complex secondary air bubble removal operations with existing applicators. This applicator offers the advantages of rapid air venting, fewer air bubbles, good effect, and essentially completing the application process in one step without the need for secondary air bubble removal.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] A screen protector applicator with a rapid venting structure is an integrally molded blister pack, comprising a positioning frame 1 and a support device 2 located at the bottom of the positioning frame 1 and connected to the positioning frame 1. The positioning frame 1 is higher than the support device 2 and surrounds the support device 2. The positioning frame 1 includes a long side and a short side. The positioning frame 1 is adapted to the external dimensions of the device to be covered, for accurately fixing the device and playing a positioning role, ensuring that the screen protector can accurately cover the screen during application, avoiding misalignment or displacement. The positioning frame 1 has a first notch 12 on its long side. When the device is placed on the applicator, the first notch 12 facilitates the operator's handling of the device. The first notch 12 can be located at any position on the long side of the positioning frame 1, preferably at a position opposite to the side button of the device. The positioning frame 1 has an operating part 14, which is located on the same plane as the support device 2 and outside the positioning frame 1. The operating part 14 is used by the operator to pick up the applicator. A fixing block 11 is provided on the inner side of the connection between the positioning frame 1 and the support device 2. The fixing block 11 protrudes slightly from the inner side of the positioning frame 1. When the device is fixed into the positioning frame 1, the presence of the fixing block 11 causes an interference fit between the applicator and the device, thereby locking the device and making it difficult for the device to move. An auxiliary venting structure 21 is provided in the middle part of the support device 2, parallel to its long side. The exhaust structure 21 includes, but is not limited to, shapes with a rectangular or circular cross-section. The shape of the auxiliary exhaust structure 21 includes, but is not limited to, long protrusions or columns. The upper surface of the auxiliary exhaust structure 21 is higher than the surface of the main body of the carrier device 2. The edge of the carrier device 2 is provided with a support portion 22. The height of the support portion 22 is slightly lower than the height of the auxiliary exhaust structure 21. The auxiliary exhaust structure 21 causes the tempered glass film to form a slightly protruding middle part parallel to the long side when placed on the carrier device 2, with the two sides slightly lower than the middle part. This allows the middle part to contact the device screen first when applying the film, facilitating exhaust to both sides. The middle part is relative to the edge and is not limited to the exact center or midpoint. The first short side of the carrier device 2 is provided with a second notch 24. The second notch 24 is formed by the missing part of the carrier device 2. The pull strip is pulled out through the second notch 24 when applying the film to complete the application.The second short side of the positioning frame 1 is provided with a third notch 13. The bottom of the third notch 13 is flush with the bottom of the supporting device 2. A protrusion 23 is provided on the bottom of the third notch 13. The protrusion 23 includes two protrusions: a cylindrical part and an oblong part. The two ends of the cross-section of the oblong part are semicircular, and the long side is a straight line. The protrusion 23 is used to initially fix and position the protective film during the film application operation. The film applicator is an integrally molded blister part. The protruding part on the edge of the positioning frame 1, the auxiliary arrangement knot The structure 21, the fixing block 11, and the support part 22 are all hollow convex strips. The film applicator is an integrally formed sheet structure, which is to cut the sheet, heat and soften it, adsorb and form it, and finally cool and demold it for trimming and quality inspection to complete the production. Vacuum forming is usually used, which involves placing the heated and softened plastic sheet above the mold, using a vacuum pump to extract the air between the mold and the sheet, and using atmospheric pressure to make the sheet adhere to the mold and form it. The wall thickness deviation of the vacuum-formed product is usually 0.3mm±0.1mm, and the thickness may be reduced by 10%-20% at the corners.

[0022] In another embodiment, the second notch 24 is the missing part of the positioning frame 1 on the first short side. The pull strip is pulled out through the second notch 24 during film application to complete the film application.

[0023] During the film application process, the protective film is first placed on the carrier device 2. The protective film includes a film for attaching to the device screen and a thin film to prevent contamination. The thin film has a pull strip. Once the device screen and the protective film are in the correct positions, pulling the pull strip will peel off the film, completing the bonding between the device screen and the protective film. The protective film has through holes that mate with the protrusions 23. The through holes are fitted onto the protrusions 23 for initial fixation and positioning of the protective film. Then, the device screen is placed face down opposite the protective film, and the pull strip is pulled. Due to the protrusions of the auxiliary arrangement structure 21, the middle part of the protective film contacts the device screen first. Based on the principle of electrostatic adsorption, the micro-charges on the material surface form an electrostatic attraction with the glass screen, allowing bonding without glue and smooth air expulsion from the middle, achieving a better and faster film application effect.

[0024] The above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments, and many similar modifications are possible. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the scope of protection of this utility model.
