Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories, and in particular to a sliding film applicator and film applicator assembly. Background Technology

[0002] As electronic devices become more feature-rich, their screens take up larger and larger areas. To protect these screens from scratches and damage during daily use, protective films are often applied. However, during the manual application process, it can be difficult to align the protective film with the screen.

[0003] The biggest challenge in applying a screen protector is precisely aligning it with the screen of the electronic device. Traditional manual application often results in misaligned application, leading to waste. Therefore, most users need to use a screen protector applicator to accurately apply the protector to the screen of their electronic devices.

[0004] Existing film applicators use rollers on the applicator to apply the film. Most of these roller applicators slide directly between the base and the top cover with the rollers, allowing the rollers to push the protective film to achieve the application process. However, the roller movement trajectory of these roller applicators has a large error. During the application process, the rollers are prone to shaking, resulting in poor stability, reduced application efficiency, and decreased application quality.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a sliding film applicator and film applicator assembly. This is achieved through the cooperation of a first sliding engagement part on the base and a second sliding engagement part on the slider, as well as a double sliding guide structure involving a sliding guide rail on the side of the base and a sliding part on the side of the slider. This double sliding limiting cooperation ensures precise and stable sliding of the sliding film applicator assembly on the base, guaranteeing that the scraper can move at a uniform speed along a preset path. This allows the force exerted by the scraper during pressing and scraping to be more evenly transmitted to the protective film surface, improving air venting efficiency and reducing air bubble residue.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A sliding film applicator includes a base and a sliding film applicator assembly. The base has a receiving groove. The sliding film applicator assembly includes a sliding member and a scraping member, with the scraping member disposed on the sliding member. Sliding guide rails are also provided along the outer edges of both sides of the base. A first sliding engagement portion is provided on the outer side of the receiving groove.

[0009] The sliding member is provided with a second sliding engagement part for sliding engagement with the first sliding engagement part and a sliding part for sliding engagement with the sliding guide rail on the side facing the receiving groove. The sliding part is located next to the second sliding engagement part. The sliding film assembly is slidably connected to the base, so that the second sliding engagement part is slidably connected to the first sliding engagement part and the sliding part is slidably connected to the sliding guide rail, so as to drive the scraper to move from one end of the receiving groove to the other end, so as to press and scrape to expel air.

[0010] As a preferred embodiment, the sliding member has a mounting groove on the end facing the receiving groove, and the scraper is installed and positioned in the mounting groove.

[0011] As a preferred embodiment, the scraper is made of a soft material.

[0012] As a preferred embodiment, the scraper is made of sponge or foam material.

[0013] As a preferred embodiment, the base is also provided with an elastic buffer structure, which is located at the front of the receiving groove. When the sliding member slides along the base, the lower edge of the scraper member contacts and compresses the elastic buffer structure, thereby slowing down the sliding of the sliding member when it approaches the front of the placement groove.

[0014] As a preferred embodiment, the elastic buffer structure is provided with positioning posts for positioning the release film.

[0015] As a preferred embodiment, the first sliding mating part and the sliding guide rail extend along the length direction of the base.

[0016] As a preferred embodiment, the first sliding engagement part is a sliding groove, and the second sliding engagement part is a sliding protrusion.

[0017] As a preferred embodiment, the length of the scraper is less than or equal to the length of the slider, and the length of the second sliding mating part is greater than or equal to the length of the receiving groove.

[0018] A film applicator assembly includes a protective film and an applicator, wherein the applicator is a sliding applicator as described in any of the above claims, and the protective film includes at least a release film with positioning holes. When the protective film is placed in a receiving groove, the positioning holes of the release film are exposed outside the receiving groove and are adapted to a positioning post.

[0019] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses the cooperation of the first sliding mating part on the base and the second sliding mating part on the sliding member, as well as the cooperation of the double sliding guide structure of the sliding guide rail on the side of the base and the sliding part on the side of the sliding member. In this way, by using the double sliding limit cooperation, the sliding film assembly slides accurately and stably on the base, effectively avoiding skew, shaking or jamming during the sliding process, ensuring that the scraper can move at a uniform speed along the preset path, and allowing the force of the scraper to be transmitted more evenly to the surface of the protective film when pressing and scraping, improving the air venting efficiency, reducing air bubble residue, and ensuring the flatness after film application.

[0039] A sliding film applicator includes a base 10 and a sliding film applicator assembly 20.

[0040] The base 10 is provided with a receiving groove 11; the receiving groove 11 is also provided with a clearance position 111 for avoiding the lens position of electronic devices; the rear end of the film applicator base 10 is provided with a stop post 12 for limiting the sliding range of the sliding member 21, and the stop post 12 is also provided with a buckle 121 for fixing the mobile phone protective film 30. The buckle 121 is higher than the product screen to prevent premature contact during film application, which could cause air bubbles.

[0041] The base 10 is also provided with sliding guide rails 13 on both outer edges, and the receiving groove 11 is provided with a first sliding mating part 14 on the outer side.

[0042] The sliding film application assembly 20 includes a sliding member 21 and a scraper member 22. The scraper member 22 is disposed on the sliding member 21. Preferably, the sliding member 21 has an installation groove 211 on one end facing the receiving groove 11, and the scraper member 22 is installed and positioned in the installation groove 211.

[0043] Preferably, the scraper 22 is made of a soft material. Preferably, the scraper 22 is made of sponge or foam material. The material design of the scraper 22 allows it to deform, thus preventing the scraper 22 from damaging the protective film 30 during the application process.

[0044] The sliding member 21 has a second sliding engagement portion 212 for sliding engagement with the first sliding engagement portion 14 and a sliding portion 213 for sliding engagement with the sliding guide rail 13 on the side facing the receiving groove 11. The sliding portion 213 is located beside the second sliding engagement portion 212. The sliding film assembly 20 is slidably connected to the base 10, such that the second sliding engagement portion 212 is slidably connected to the first sliding engagement portion 14, and the sliding portion 213 is slidably connected to the sliding guide rail 13, so as to drive the scraper 22 from one end of the receiving groove 11 to the other end to press and scrape to expel air. In this embodiment, the sliding direction of the sliding film assembly 20 is from front to back.

[0045] Preferably, the first sliding engagement portion 14 and the sliding guide rail 13 extend along the length direction of the base 10. Preferably, the first sliding engagement portion 14 is a sliding groove, and the second sliding engagement portion 212 is a sliding protrusion. Preferably, the length of the scraper 22 is less than or equal to the length of the slider 21, and the length of the second sliding engagement portion 212 is greater than or equal to the length of the receiving groove 11.

[0046] Preferably, the base 10 is further provided with an elastic buffer structure 15, which is disposed on the front side of the receiving groove 11. When the sliding member 21 slides along the base 10, the lower edge of the scraper 22 contacts the elastic buffer structure 15 and compresses the elastic buffer structure 15. Through the elastic deformation resistance of the elastic buffer structure 15, the sliding member 21 gradually slows down its sliding speed when it approaches the front side of the placement groove (before reaching the top of the product screen), preventing premature contact during film application and causing air bubbles.

[0047] Preferably, the elastic buffer structure 15 is provided with positioning posts for positioning the release film.

[0048] A film applicator assembly includes a protective film 30 and an applicator 40, wherein the applicator 40 is the aforementioned sliding applicator. The protective film 30 includes at least a release film with positioning holes. When the protective film 30 is placed in a receiving groove 11, the positioning holes of the release film are exposed outside the receiving groove 11 and adapted to a positioning post. In this embodiment, the structure of the protective film 30 is well-known in the art and will not be described in detail here.

[0049] The key design feature of this invention lies in the cooperation between the first sliding engagement part on the base and the second sliding engagement part on the slider, as well as the cooperation between the sliding guide rail on the side of the base and the sliding part on the side of the slider. In this way, the double sliding limit cooperation makes the sliding film assembly slide accurately and stably on the base, effectively avoiding skew, shaking or jamming during the sliding process, ensuring that the scraper can move at a uniform speed along the preset path, and allowing the force of the scraper to be transmitted more evenly to the surface of the protective film when pressing and scraping, improving air venting efficiency, reducing air bubble residue, and ensuring the flatness after film application.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
