Description

A type of screen protector applicator Technical Field

[0001] This invention relates to the field of mobile phone auxiliary equipment, and in particular to a screen protector applicator. Background Technology

[0002] With the development of technology and the progress of society, mobile phones have become an indispensable part of people's lives. Because mobile phone screens are relatively fragile and easily broken, people usually use screen protectors to protect them from shattering. Generally, screen protectors include tempered glass screen protectors and release films that can be detachably attached to the tempered glass screen protector. The side where the tempered glass screen protector and the release film connect is an adhesive side. The application process involves peeling the release film off the tempered glass screen protector and then sticking the adhesive side of the tempered glass screen protector to the mobile phone screen, thus securing the tempered glass screen protector to the phone.

[0003] To ensure a smooth, bubble-free application of the screen protector, people often use a screen protector applicator. These applicators typically have a slot to hold the protective film and the phone, as well as a pull-out film to remove the release liner. By pulling out the release liner, the tempered glass screen protector is naturally adhered to the phone screen.

[0004] While existing screen protector applicators can assist users in applying screen protectors, the process is often complicated by the fact that the applicator is usually placed upside down on the phone screen. Before the screen protector is applied, gravity can cause it to shift, making the application difficult and resulting in poor adhesion. As a result, most screen protector applicators on the market currently use adhesive to fix the release liner to the applicator, requiring the screen protector to have release liners on both sides. This double-sided release liner design increases the production cost of the screen protector.

[0005] Therefore, a new technology needs to be developed to solve the above-mentioned technical problems. Technical solutions

[0006] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a film applicator that can save on the production cost of film components, has a simpler structure, and is easier to manufacture.

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

[0008] A screen protector applicator includes an applicator body and a screen protector assembly. The applicator body includes a main body portion and two arc-shaped baffles. The two arc-shaped baffles are formed at the upper end of the main body portion and are arranged symmetrically from left to right. The two arc-shaped baffles form a receiving groove for placing a mobile phone. The front ends of the two arc-shaped baffles are spaced apart to form a notch, and the rear ends of the two arc-shaped baffles are spaced apart to form an outlet groove. The inner bottom of each of the two arc-shaped baffles has a strip groove that communicates with the receiving groove and extends to the rear end of the arc-shaped baffle and communicates with the outlet groove.

[0009] The membrane assembly includes a release film and a tempered film stacked on top of each other. The membrane assembly is installed into the receiving groove from back to front. The tempered film is located in the receiving groove, the release film is stuck in the strip groove, the front end of the release film is bonded to the notch, and the rear end of the release film extends outward beyond the rear end of the arc-shaped baffle.

[0010] As a preferred embodiment, the front end of the release film is adhered to the notch by adhesive.

[0011] As a preferred embodiment, the front end of the release film has an adhesive portion that protrudes forward; the adhesive portion is adhered to the notch and extends forward beyond the notch.

[0012] As a preferred embodiment, the release film has a pull-out portion formed at its rear end, which extends rearward through the strip groove beyond the rear end of the main body.

[0013] As a preferred embodiment, the release film is a single-sided release film, and the lower surface of the single-sided release film is adhered to the upper surface of the tempered film.

[0014] As a preferred option, the curved baffle on the left side is provided with a clearance to avoid the phone's keypad.

[0015] As a preferred embodiment, the main body is provided with a plurality of through holes that penetrate the upper and lower surfaces of the main body corresponding to the arc-shaped baffle.

[0016] As a preferred embodiment, the lower end of the arc-shaped baffle is integrally connected to the upper end of the main body, and the lower end of the arc-shaped baffle is provided with a plurality of grooves that are concave upwards. The grooves are connected to the through holes and the grooves are connected to the strip grooves.

[0017] As a preferred embodiment, the arc-shaped baffle includes a straight plate portion and two arc-shaped portions, with the two arc-shaped portions integrally connected to the front and rear ends of the straight plate portion, respectively.

[0018] Compared with the prior art, the present invention has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves forming a strip groove at the inner bottom of the arc-shaped baffle, connecting the strip groove with the receiving groove, and extending the strip groove through to the rear end of the arc-shaped baffle and connecting to the outlet groove. The membrane assembly includes a release film and a tempered film stacked on top of each other, with the tempered film located in the receiving groove and the release film held in the strip groove. In this way, one side of the release film can be bonded to the tempered film, and the other side can be held in place by the film applicator body. This allows the membrane assembly to be stably installed on the film applicator body. Even if the film applicator is turned upside down, the membrane assembly will not fall off, which is more conducive to the film application operation. Furthermore, by designing the membrane assembly to consist of a release film and a tempered film, only a single piece of release film needs to be placed on the tempered film on one side of the membrane assembly. This can save on the production cost of the membrane assembly, and the structure is simpler and easier to manufacture. Attached Figure Description

[0035] Please refer to Figures 1 to 7, which show the specific structure of an embodiment of the present invention.

[0036] As shown in Figures 1 to 7, a screen protector applicator includes an applicator body and a screen protector assembly. The applicator body includes a main body portion 10 and two arc-shaped baffles 20. The two arc-shaped baffles 20 are formed at the upper end of the main body portion 10 and are arranged symmetrically on the left and right sides, forming a receiving groove 30 for placing a mobile phone. Each arc-shaped baffle 20 includes a straight plate portion 23 and two arc-shaped portions 24, which are integrally connected to the front and rear ends of the straight plate portion 23, respectively. The arc-shaped baffle 20 on the left side is provided with a clearance position 21 to avoid the mobile phone keypad, and the clearance position 21 is formed on the straight plate portion 23. The front ends of the two arc-shaped baffles 20 are arranged to form a notch 40, and the rear ends of the two arc-shaped baffles 20 are arranged to form an outlet groove 50. The inner bottom of the two arc-shaped baffles 20 is formed with a strip groove 60, which is connected to the receiving groove 30. The strip groove 60 extends to the rear end of the arc-shaped baffle 20 and is connected to the outlet groove 50.

[0037] As shown in Figures 1 to 3, the membrane assembly includes a release film 70 and a tempered film 80 stacked vertically. The membrane assembly is inserted into the receiving groove 30 from back to front. The tempered film 80 is located within the receiving groove 30, and the release film 70 is secured within the strip groove 60. The front end of the release film 70 is adhered to the notch 40, and the rear end of the release film 70 extends rearward beyond the rear end of the arc-shaped baffle 20. By designing the membrane assembly to consist of the release film 70 and the tempered film 80, only a single sheet of release film 70 needs to be placed on one side of the tempered film 80. This reduces production costs, simplifies the structure, and makes manufacturing easier.

[0038] As shown in Figures 1 to 3, the front end of the release film 70 is bonded to the notch 40 by adhesive 90. Specifically, in this embodiment, the front end of the release film 70 has an adhesive portion 71 protruding forward; the adhesive portion 71 is bonded to the notch 40 by adhesive 90 and extends forward beyond the notch 40. The rear end of the release film 70 has a pull-out portion 72, which extends rearward through the strip groove 60 beyond the rear end of the body portion 10.

[0039] As shown in Figure 3, the release film 70 is a single-sided release film 70. The lower surface of the single-sided release film 70 is adhered to the upper surface of the tempered glass film 80. Thus, one side of the single-sided release film 70 is adhered to the tempered glass film 80, and the other side is secured to the main body of the applicator. The length of the single-sided release film 70 is greater than the length of the tempered glass film 80, and the length of the single-sided release film 70 is greater than the length of the main body of the applicator.

[0040] As shown in Figures 4 to 7, the main body 10 is provided with a plurality of through holes 11 corresponding to the arc-shaped baffle 20, which penetrate the upper and lower surfaces of the main body 10. The lower end of the arc-shaped baffle 20 is integrally connected to the upper end of the main body 10, and the lower end of the arc-shaped baffle 20 is provided with a plurality of grooves 22 that are recessed upward. The grooves 22 are connected to the through holes 11 and to the strip groove 60.

[0041] When using, place the screen protector applicator upside down on the phone (or place the phone with the camera facing up into the applicator's receiving slot 30), and then pull the release film 70's pull-out part 72 towards the exit slot 50 to remove the release film 70 so that the tempered glass screen protector 80 can be applied to the phone. This completes the screen protector application process, which is simple and convenient.

[0042] In summary, the key design feature of this invention lies in the formation of a strip-shaped groove at the inner bottom of the arc-shaped baffle, connecting the groove to the receiving groove and extending beyond the rear end of the arc-shaped baffle to the outlet groove. The membrane assembly comprises a release film and a tempered film stacked on top of each other, with the tempered film located within the receiving groove and the release film secured within the strip-shaped groove. This allows one side of the release film to adhere to the tempered film, while the other side is secured to the applicator body. This ensures the membrane assembly is securely mounted on the applicator body, preventing it from falling off even when the applicator is inverted, thus facilitating the applicator operation. Furthermore, designing the membrane assembly as consisting of a release film and a tempered film allows for the use of a single-sided release film covering the tempered film, reducing production costs and simplifying the structure for easier manufacturing.

[0043] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
