[0001] The present application relates to the technical field of screen protection devices, and in particular to a roller-type film-sticking auxiliary mechanism. Background Art

[0002] With the rapid development of technology, curved screen mobile phones have gradually taken the leading position in the market. However, due to its unique curved screen design, film application has become a major problem for consumers. Traditional film application methods are often difficult to adapt to the characteristics of curved screens, resulting in poor film application effects, which can easily cause dissatisfaction and trouble for consumers, greatly reducing user satisfaction.

[0003] At present, protective films are highly favored in the market for their excellent protective performance and good hand feel. Protective films are hard and scratch-resistant, which can effectively protect mobile phone screens from damage. However, for the film application of curved screen mobile phones, most of the existing film application tools still remain on the traditional scraper structure.

[0033] With the rapid development of technology, curved screen mobile phones have gradually taken the leading position in the market. However, due to its unique curved screen design, film application has become a major problem for consumers. Traditional film application methods are often difficult to adapt to the characteristics of curved screens, resulting in poor film application effects, which can easily cause dissatisfaction and trouble for consumers, greatly reducing user satisfaction.

[0034] At present, protective films are highly favored in the market for their excellent protective performance and good hand feel. Protective films are hard and scratch-resistant, which can effectively protect mobile phone screens from damage. However, for the film application of curved screen mobile phones, most of the existing film application tools still remain on the traditional scraper structure.

[0035] Due to the flexibility of the curved screen, bubbles are often prone to appear during the film application process. When using a scraper to apply the film, for novices who are not familiar with the film application operation, it is easy to apply force unevenly when using the scraper, and bubbles may easily form between the protective film and the screen, resulting in poor adhesion.

[0036] Based on this, the present application provides a roller-type film-sticking auxiliary mechanism to solve the above-mentioned technical problems. The technical solutions proposed in the present application are described in detail one by one below.

[0037] Reference Figure 1 and Figure 2The present application provides a roller-type film-applying auxiliary mechanism, comprising: a housing 100 and a rolling assembly 200, wherein a sliding channel 110 is provided in the housing 100, wherein a positioning groove 120 is provided in the sliding channel 110, wherein at least two positioning blocks 130 are provided on each inner wall of the positioning groove 120, wherein the positioning blocks 130 are provided with a limiting groove 131 matching the size of the electronic device, so that when the electronic device is placed in the positioning groove 120, its edge is against the groove wall of each limiting groove 131; the sliding channel 110 is provided with a positioning structure on the side of the positioning groove 120 , used to fix the position of the protective film; the rolling assembly 200 includes a sliding frame 210, a long roller 220, a short roller 230 and a handle 240. The two sides of the sliding frame 210 can be slidably connected to the two sides of the shell 100 and are located above the sliding channel 110. The long roller 220 and the short roller 230 can be rotatably arranged on the side of the sliding frame 210 close to the sliding channel 110, and the short roller 230 is located on the front side of the long roller 220 along the sliding direction of the sliding frame 210; the handle 240 is detachably arranged on the side of the sliding frame 210 away from the sliding channel 110.

[0038] A sliding channel 110 is provided in the shell 100, and a positioning block 130 is provided on the inner wall of each side of the positioning groove 120. The shell 100 is a universal auxiliary mechanism template. According to the sizes of different electronic devices, the positioning block 130 can be processed by laser or other means to form a limiting groove 131 that matches the electronic device. When the electronic device is placed in the positioning groove 120, the edge of the electronic device is against the groove wall of each limiting groove 131, and the limiting grooves 131 on all sides play a role in positioning the electronic device. In the roller-type film-sticking auxiliary mechanism of the present application, it does not need to be remodeled and cut according to different models of electronic devices. It only needs to process the positioning block 130 according to the size of the electronic device, which improves the versatility of the electronic device film-sticking auxiliary mechanism, improves the production efficiency of the electronic device film-sticking auxiliary mechanism, and saves labor production costs.

[0039] In addition, the handle 240 of the rolling assembly 200 is detachably disposed on the sliding frame 210 , and the handle 240 can be removed for packaging before leaving the factory, which can reduce the overall packaging space.

[0040] During use, the positioning film at the top of the protective film is fixed above the electronic device through the positioning structure, so that the protective film can face the screen of the electronic device more accurately. Then tear off the dust film at the bottom of the protective film, install the sliding frame 210 on the housing 100, and pull the handle 240 to make the long roller 220 and the short roller 230 roll on the screen. The rolling method improves the uniformity of force application and simplifies the film application operation. The bubbles generated during the film application process can be reasonably squeezed out, and greater force can be applied during the rolling process. In addition, the short roller 230 is used for pre-pressing before pressing, and then the long roller 220 is used for further pressing, so that the edge of the curved screen can better fit with the protective film, thereby further improving the film application effect.

[0041] Reference Figures 1 to 3 It can be understood that the outer walls of both sides of the housing 100 are provided with guide ridges 101, and the two sides of the sliding frame 210 are respectively provided with guide grooves 211 matching the guide ridges 101. The matching design of the guide ridges 101 and the guide grooves 211 ensures the precise positioning and stable sliding of the sliding frame 210 on the housing 100, which avoids misalignment or shaking during movement or operation, and improves the stability and safety of the product. At the same time, the precise and stable positioning, fast and simple assembly process, all bring better user experience.

[0042] Reference Figure 4 It can be understood that two first fixing plates 250 are arranged opposite to each other on the side of the sliding frame 210 away from the sliding channel 110, and first fixing holes 251 are arranged in the first fixing plates 250, and a first opening 252 is arranged on the top of one of the first fixing plates 250, and the first opening 252 is communicated with the corresponding first fixing hole 251, and the two sides of the handle 240 are respectively inserted into the corresponding two first fixing holes 251. The handle 240 is fixed in the first fixing hole 251 by inserting, so that the installation and removal of the handle 240 become simple and quick, which not only improves the production efficiency, but also facilitates the subsequent maintenance and replacement operations. By providing a first opening 252 on the top of one of the first fixing plates 250, the first opening 252 is communicated with the corresponding first fixing hole 251, so that the handle 240 can be taken out from the first fixing plate 250, and the handle 240 can be disassembled for packaging when leaving the factory, which can reduce the overall packaging space and also facilitate the replacement and maintenance of the handle 240.

[0043] It is understandable that the front end of the handle 240 is wrapped with cloth (not shown in the figure). After the long roller 220 and the short roller 230 push, if there are still some bubbles between the protective film and the screen of the electronic device that cannot be discharged, the handle 240 can be removed from the sliding frame 210, and the bubbles can be pushed out by using the front end of the handle 240. The cloth is relatively soft and can contact the protective film without damaging the protective film. Even if a large force is applied to push the handle 240, no scratches will be left on the protective film.

[0044] Reference Figure 5 and Figure 6 It can be understood that two oppositely arranged second fixing plates 260 and two oppositely arranged third fixing plates 270 are provided on one side of the sliding frame 210 close to the sliding channel 110, and the second fixing plate 260 is located at the front side of the third fixing plate 270 along the sliding direction of the sliding frame 210; a second fixing hole 261 is provided in the second fixing plate 260, and a second opening 262 is provided at the top of one of the second fixing plates 260, and the second opening 262 is communicated with the corresponding second fixing hole 261, and the two ends of the short roller 230 can be rotatably set in the corresponding two second fixing holes 261; a third fixing hole 271 is provided in the third fixing plate 270, and a third opening 272 is provided at the top of one of the third fixing plates 270, and the third opening 272 is communicated with the corresponding third fixing hole 271, and the two ends of the long roller 220 can be rotatably set in the corresponding two third fixing holes 271. The short roller 230 and the long roller 220 are fixed in the second fixing hole 261 and the third fixing hole 271 by insertion, so that the short roller 230 and the long roller 220 can be installed, and the top of one of the second fixing plates 260 and the third fixing plate 270 is respectively provided with a second opening 262 and a third opening 272, so that the disassembly of the short roller 230 and the long roller 220 becomes simple and quick, which not only improves the production efficiency, but also facilitates the subsequent maintenance and replacement operations.

[0045] It is understandable that the short roller 230 and the long roller 220 are provided with a first bearing and a second bearing (not shown in the figure) at both ends, the short roller 230 is arranged in the second fixing hole 261 through the first bearing, and the long roller 220 is arranged in the third fixing hole 271 through the second bearing. By providing the first bearing and the second bearing at both ends of the short roller 230 and the long roller 220, respectively, the friction force of the short roller 230 and the long roller 220 during rotation can be reduced, and the smoothness of the rotation of the short roller 230 and the long roller 220 is improved. In addition, as an independent mechanical component, the bearing can be maintained and replaced separately, reducing the maintenance cost and time.

[0046] It can be understood that the length of the handle 240 is less than or equal to the width of the sliding channel 110. When the roller-type film-applying auxiliary mechanism of the present application is stored, the handle 240 can be disassembled and placed in the sliding channel 110, thereby improving the utilization of space and reducing the overall occupied space of the roller-type film-applying auxiliary mechanism.

[0047] Reference Figure 2 It can be understood that the positioning structure includes a first positioning column 141 and a second positioning column 142 respectively arranged on both sides of the positioning groove 120 along the length direction, two first positioning columns 141 and two second positioning columns 142 are provided, the distance between the two first positioning columns 141 is not equal to the distance between the two second positioning columns 142, and the first positioning column 141 is located at the front side of the second positioning column 142 along the sliding direction of the sliding frame 210. The inequality between the distance between the first positioning columns 141 and the distance between the two second positioning columns 142 can play a foolproof role and guide the mobile phone film to be correctly installed on the roller-type film-sticking auxiliary mechanism.

[0048] Continue to refer to Figure 2 A first transition block 150 is provided between the first positioning column 141 and the positioning groove 120, and a second transition block 160 is provided between the second positioning column 142 and the positioning groove 120. When the electronic device is placed in the positioning groove 120, the first transition block 150 and the second transition block 160 are flush with the upper surface of the electronic device. When the mobile phone film is covered on the screen, a scraper is needed to push the mobile phone film, that is, the scraper is used to push the mobile phone film to discharge the bubbles between the mobile phone film and the screen. In the process of the scraper pushing, the mobile phone film is generally scraped from one side to the other side, that is, from the position of the first positioning column 141 to the second positioning column 142. There is usually a hollow distance between the first positioning column 141 and the screen. The first transition block 150 is provided to prevent the scraper from sinking and lifting during pushing, thereby bringing bubbles between the mobile phone film and the screen, affecting the film sticking effect. By setting the first transition block 150 to fill the hollow area between the first positioning column 141 and the screen, the scraper can be smoothly pushed from the position of the first positioning column 141 to the mobile phone film. Similarly, the function of the second transition block 160 is similar to that of the first transition block 150, which will not be repeated here. By adding the first transition block 150 and the second transition block 160, bubbles are prevented from entering between the mobile phone film and the screen, thereby improving the film-sticking effect of the electronic device.

[0049] Reference Figure 1 and Figure 2At least one avoidance hole 121 is provided at the bottom of the positioning groove 120, and the avoidance hole 121 is used to place the camera of the electronic device. In existing electronic devices, the camera often protrudes from the bottom cover of the mobile phone. In order to prevent the camera of the electronic device from being scratched by the positioning groove 120 and prevent the electronic device from being placed unevenly in the positioning groove 120, it can not only ensure the overall structural strength of the housing 100, but also reduce material consumption and production costs.

[0050] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
