Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen protector technology, and in particular to a screen protector application auxiliary tool. Background Technology
[0002] In today's world of ubiquitous electronic devices, tempered glass screen protectors, as crucial screen protection accessories, directly impact user experience with their adhesion. Traditional manual application relies on the operator's experience and skills, but due to a lack of precise positioning methods and automated application mechanisms, issues such as air bubbles, dust residue, or misalignment often arise during the application process, leading to application failures or affecting screen display quality. To address these pain points, screen protector application aids have emerged, their core being to improve the convenience and accuracy of application through structural innovation.
[0003] Currently, most screen protector application tools on the market use basic positioning frames or template designs. These tools typically guide users to manually align the tempered glass screen protector through physical limiting structures (such as grooves or protrusions), or use adhesive materials for temporary fixation. Technically, they mainly rely on the user observing the relative position of the screen edge and the tool for adjustment, and the application process still requires manual pressing of the screen protector to remove air bubbles. Although some tools include dust removal stickers, the dust removal step is independent of the application process and must be completed by the user in separate steps.
[0004] However, these traditional application aids have some problems. Lacking dynamic positioning and automatic application capabilities, tempered glass screen protectors are prone to misalignment during manual application due to hand tremors or angular deviations, especially on curved or irregularly shaped screens, where manual adjustment becomes even more difficult. Furthermore, manually pressing to release air bubbles cannot completely prevent their formation, and touching the inside of the screen with fingers during the process introduces new sources of dust and contamination. These issues directly affect the success rate and final result of screen protector application, urgently requiring a new type of application aid capable of precise positioning and automatic application. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a screen protector application tool, which aims to improve the problem of tempered glass screen protectors being difficult to place accurately and easily shifting during the application process when applied manually, thus affecting the quality of the screen protector application.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a film application auxiliary tool, comprising a housing, an automatic application component provided on the outer wall of the housing, and an auxiliary film application component provided on the surface of the housing;
[0007] The automatic bonding component includes a spring sheet, the inner wall of which is disposed on the outer wall of the outer shell. A limiting block 1 is formed in the inner wall of the outer shell, a limiting groove 1 is formed in the outer wall of the outer shell, a limiting block 2 is fixedly connected to the inner wall of the outer shell, and the limiting groove 2 is symmetrically arranged on both sides of the outer shell. The limiting block 1 can be set inside the limiting groove 2 as needed.
[0008] Furthermore, the auxiliary film application assembly includes a positioning block, the outer wall of which is fixedly connected to the surface of the outer shell, a positioning film is attached to the inner wall of the outer shell, a tempered glass film is attached to the surface of the positioning film, a dust storage film is attached to the surface of the tempered glass film, and a positioning hole is formed on the outer wall of the positioning film.
[0009] Furthermore, the spring can change its position and shape according to different pressures.

[0011] Furthermore, the positioning film is used to position the tempered glass film.
[0012] Furthermore, the outer wall of the limiting block is disposed inside the limiting groove, and the limiting block is used to limit the tempered glass film.
[0013] Furthermore, the spring clip is positioned above the tempered glass film, and the spring clip is used to automatically pop out and adhere the tempered glass film.
[0014] Furthermore, the outer wall of the tempered glass film is attached to the inner wall of the limiting block two, and the limiting block two is used to fix the tempered glass film.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the tempered glass film is placed in the outer shell, the limiting block is used to limit it, the spring sheet retracts and rebounds, and the dust-collecting film is applied after dust removal.

It achieves automatic application, reduces the error of manual operation, improves the accuracy and efficiency of film application, and accurately completes the film application operation.
[0017] 2. In this utility model, the tempered glass film is first precisely positioned by the cooperation of the positioning block and the positioning hole on the positioning film. After being placed in the outer shell, the various components work together to fix the tempered glass film. Before bonding, the dust storage film is cleaned of dust. Finally, the spring sheet pops the tempered glass film out for bonding, thereby achieving the purpose of improving the quality of film bonding, reducing the probability of film bonding failure, and making the film bonding operation more convenient.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a film application auxiliary tool, comprising a housing 1, an automatic application component provided on the outer wall of the housing 1 for automatically pushing the tempered glass film 3, and an auxiliary film application component provided on the surface of the housing 1 for positioning the tempered glass film 3;
[0026] The automatic bonding component includes a spring sheet 7, which stores and releases energy through elastic deformation to achieve automatic pop-out bonding of the tempered glass film 3. The inner wall of the spring sheet 7 is set on the outer wall of the outer shell 1. A limiting block 9 is formed on the inner wall of the outer shell 1, which cooperates with the limiting groove 8. The edge of the tempered glass film 3 is bidirectionally limited by rotation and rebound. The outer wall of the outer shell 1 is provided with the limiting groove 8. The inner wall of the outer shell 1 is fixedly connected with the limiting block 10. The two sides of the outer shell 1 are symmetrically provided with the limiting groove 11. The limiting block 9 can be set inside the limiting groove 11 as needed.
[0027] Specifically, when using the screen protector application tool, the tempered glass screen protector 3 is placed inside the outer shell 1. The tempered glass screen protector 3 presses against the limiting block 9, causing it to rotate within the limiting groove 8. Subsequently, the two limiting blocks 9 rebound to limit the tempered glass screen protector 3, while the two limiting blocks 10 fix the tempered glass screen protector 3. When the tempered glass screen protector 3 is fully inserted into the outer shell 1, it will compress the spring 7 to shrink it. During the application stage, the spring 7 rebounds to push the tempered glass screen protector 3 out of the outer shell 1, achieving automatic application.
[0028] Reference Figure 1 and Figure 2 The auxiliary film application component includes a positioning block 5, the outer wall of which is fixedly connected to the surface of the outer shell 1. A positioning film 2 is attached to the inner wall of the outer shell 1. The positioning film 2 provides a reference position for the tempered glass film 3 through the cooperation of the positioning hole 6 and the positioning block 5. The tempered glass film 3 is attached to the surface of the positioning film 2. A dust collection film 4 is attached to the surface of the tempered glass film 3. The dust collection film 4 is independent of the tempered glass film 3 and completes dust removal independently through a pulling action. The positioning hole 6 is opened on the outer wall of the positioning film 2. The spring 7 can change its position according to different pressures and its shape can be adjusted. The dust collection film 4 is used to remove dust from the electronic screen. The positioning film 2 is used to position the tempered glass film 3. The outer wall of the limiting block 1 9 is set inside the limiting groove 1 8. The limiting block 1 9 is used to limit the tempered glass film 3. The spring 7 is set above the tempered glass film 3. The spring 7 is used to automatically pop out the tempered glass film 3 for application. The outer wall of the tempered glass film 3 is attached to the inner wall of the limiting block 2 10. The limiting block 2 10 is used to fix the tempered glass film 3.
[0029] Specifically, the positioning film 2 is pre-attached inside the outer shell 1, and the tempered glass film 3 and the dust collection film 4 are attached to its surface in sequence. The positioning block 5 is fixed to the surface of the outer shell 1 and connected to the positioning hole 6 on the positioning film 2, so as to accurately position the positioning film 2, which also realizes the positioning of the tempered glass film 3. Before attaching, the dust collection film 4 first contacts the electronic screen, and pulling out the dust collection film 4 can remove the dust on the screen.
[0030] Working principle: When a screen protector application tool is needed, and when it is necessary to apply the tempered glass screen protector 3 to the electronic screen, the tempered glass screen protector 3 is placed inside the outer shell 1. At this time, the tempered glass screen protector 3 presses against the limiting block 9, and the limiting block 9 rotates inside the limiting groove 8. Then, the two limiting blocks 9 rebound to limit the tempered glass screen protector 3. At this time, the two limiting blocks 10 fix the tempered glass screen protector 3. When the tempered glass screen protector 3 is inserted into the outer shell 1, it will compress the spring 7 to shrink it. Before the tempered glass screen protector 3 is applied to the electronic screen, the dust collection film 4 will first contact the electronic screen. Then, the dust collection film 4 will be pulled out to remove the dust from the electronic screen, creating a clean environment for the application of the tempered glass screen protector 3. Finally, the spring 7 rebounds to push the tempered glass screen protector 3 out of the outer shell 1, realizing automatic application and completing the entire screen protector application process. The spring 7 can change its position according to different pressures, and its shape can be adjusted.
[0031] In addition, the positioning film 2 is pre-attached inside the outer shell 1, and the tempered glass film 3 and the dust collection film 4 are sequentially attached to the surface of the positioning film 2. The positioning block 5 is fixed to the surface of the outer shell 1, and its surface is exactly connected to the inside of the positioning hole 6 of the positioning film 2. By using the cooperation between the positioning block 5 and the positioning hole 6, the positioning film 2 is accurately positioned, thereby realizing the positioning of the tempered glass film 3 attached to the positioning film 2, ensuring that the initial position of the tempered glass film 3 is accurate during the film application process.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
