Description

Technical Field

[0001] The utility model relates to the technical field of film applicators, in particular to a quick and accurate film applicator for a curved screen. Background Art

[0002] At present, in the design of mobile phone curved screens, there are two types: curved screens and micro-curved tempered films. Curved screens have strong impact resistance and a sense of technology, with a fashionable and beautiful appearance, and a smooth transition at the edges, providing a more comfortable hand-held grip. However, due to the large curvature of the curved screen, it is difficult to achieve a curved structure on all four sides of the screen. Therefore, generally, a curved surface is set on the two long sides of the screen. Such a curved screen is not easy to find a perfectly adapted film, and the film application is difficult. When applying a tempered film, it is basically necessary to use UV glue for post-curing to achieve film application, and mis-touch may occur during operation; The micro-curved tempered film is an extension of the curved screen technology, retaining some of the advantages of the curved screen to a certain extent, such as a better appearance and feel. Compared with the curved screen, the mis-touch situation has been improved. In addition, the micro-curved tempered film has a small curvature, which can achieve the design of a curved structure on all four sides of the screen, helping to achieve a better screen-to-body ratio. Moreover, when applying the micro-curved tempered film, it is simpler than the traditional curved screen. The tempered film can be directly attached to the screen through AB glue.

[0003] When applying a fully AB-glued tempered film to a micro-curved tempered film, it is necessary to ensure the accuracy of the positioning between the micro-curved tempered film and the screen to be filmed. Otherwise, it is very likely that due to a slight deviation, the curved part cannot be well aligned, resulting in bubbles after attachment. Therefore, when applying such a micro-curved tempered film, high precision is required for its positioning; A film applicator is a tool specifically used to assist in film application. It can help people attach the film to various surfaces, such as mobile phone screens, tablet computers, car glass, etc., more safely and quickly. Using a film applicator can greatly shorten the film application time and avoid the generation of air bubbles and stains; Due to the emergence of the micro-curved tempered film screen, unlike the traditional flat screen, even a slight deviation in the angle of the curved film will affect the film application effect. And when applying the traditional flat tempered film, it is easy to control the way of exhausting air from the middle to both sides to attach it to the screen. However, due to the obstruction of the curved edge of the curved tempered film and the higher requirement for the accuracy of its positioning, it will be difficult to achieve the effect of exhausting air from the middle to both rows; Therefore, it is necessary to propose an improved technical solution to solve the above existing problems.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] When in use, the user can complete the quick and precise film application operation as long as three steps are performed. The first step is to position and place the screen to be film-applied on the base and then cover the flip cover. The operation of covering the flip cover can automatically position the rolling member, the curved film and the screen to be film-applied to the correct positions; the second step is to pull out the pull belt. During the process of pulling the pull belt, the release film on the curved film can be torn off, and generally, the release film provided on the existing curved film has an electrostatic adsorption effect. In the operation of tearing it off in the reverse direction, in addition to the end portion thereof being able to push out the dust that may remain on the screen, the dust will also be further sucked out based on the adsorption effect, so as to achieve the operation of dust-free film tearing. After tearing off the curved film, it comes to the third step, that is, operating the rolling member, and sweeping and rolling the curved film through the curved surface roller, so that the curved screen can be attached to the screen to be film-applied in an orderly manner from one end to the other end by exhausting air; therefore, through this setting, the user can quickly and precisely attach the curved film to the screen to be film-applied.

[0023] By adopting a flip - type structure combined with a feeding and locking structure, it can not only quickly position the curved surface film and the screen to be pasted, but also apply a constant downward pressure to the rolling component during the rolling operation, so that the curved surface film can be rolled and attached to the screen to be pasted with a constant downward pressure, and the situation of bubbles caused by insufficient local adhesion force of the curved surface film due to uneven downward pressure will not occur.

[0024] By setting a curved surface roller, the setting of the curved surface roller can apply a greater rolling pressure to the middle part of the curved surface tempered film during the rolling process, so as to achieve the operation of exhausting air first in the middle between the curved surface tempered film and the screen to be pasted, further ensuring that no bubbles will be generated during the film - pasting process.

[0025] In the present utility model, both the rolling wheel and the curved surface film are arranged on the flip - cover. The curved surface film and the rolling component can be closely matched, which can avoid the trouble of the user assembling the curved surface film, and the screen to be pasted will not be interfered by the rolling component or the curved surface film when being placed. And through this design method, both the curved surface film and the rolling component can be pre - installed. The operator only needs to put the screen to be pasted and then can quickly complete the film - pasting operation based on the film - pasting device.

[0026] The present utility model further sets a CNC machining groove. This CNC machining groove can be further machined by CNC after the film - pasting device is injection - molded by the mold, so as to set CNC machining grooves with different sizes based on the CNC machining method according to the size structure of different screens to be pasted. Through this setting method, the manufacturing cost of the mold can be greatly reduced and the product adaptability can be improved.

[0041] See also Figures 1-9In an embodiment of the utility model, a fast and accurate film applicator for curved screen is proposed, which is used to assist the curved film 1 to be attached to the screen 2 to be attached, including: a base 10, on which a positioning groove 11 for positioning the screen 2 to be attached is arranged; a support structure 13 is formed in the positioning groove 11, and a CNC processing groove (not shown in the figure) for positioning and placing the screen 2 to be attached is opened on the support structure 13; the CNC processing groove is post-processed according to the specific size and model of the product to be attached, and the CNC processing grooves of different sizes are processed based on the same size type of film applicator through the post-CNC processing support structure 13, so that the film applicator can flexibly adapt to the positioning of electronic products of different sizes and models before CNC processing; and a hand buckle part 12 is opened at the rear end of the positioning groove 11, which is convenient for the removal operation after the screen 2 to be attached is attached.

[0042] The flip cover 20 is positioned and covered with the base 10; a covering locking structure 60 is provided between the other end of the flip cover 20 and the base 10;

[0043] A membrane fixing structure 30, which is disposed on the flip cover 20 and is used for positioning and attaching the curved surface membrane 1;

[0044] The drawstring 40 is used to tear the release film on the curved film 1 in the reverse direction and can generate static electricity to achieve the effect of dust removal. One end of the drawstring 40 can extend beyond the base 10 and the flip cover 20;

[0045] The rolling component 50 is slidably connected to the flip cover 20. The rolling component 50 has a rotatable curved roller 51. The inner diameter of the middle of the curved roller 51 is larger than the inner diameters of the two ends of the curved roller 51. The curved roller 51 is used to roll the curved film 1 onto the screen 2 to be pasted.

[0046] Before leaving the factory, the curved film 1 is attached to the film fixing structure 30. When in use, the user directly positions the screen 2 to be attached to the base 10 through the positioning groove 11, then flips the cover 20, and locks it by closing the locking structure 60. After closing, pull the drawstring 40 first to tear the release film on the curved film 1 in the opposite direction. When setting, it is necessary to set a clearance hole at the tail of the cover 20 or the base 10 for the drawstring 40 and the release film to be pulled out. After the release film is torn and pulled out, operate the rolling component 50, and use the curved roller 51 on the rolling component 50 to sweep and roll the curved screen, so that the curved screen can be attached to the screen 2 to be attached in a manner that the air is exhausted in an orderly manner from one end to the other end; therefore, through this setting, the user can quickly and accurately attach the curved film 1 to the screen 2 to be attached to the screen 2 to be attached.

[0047] By adopting a flip - type structure of the flip - cover 20 in combination with a feeding and locking structure, it can not only quickly position the curved surface film 1 and the screen 2 to be pasted, but also apply a constant downward pressure to the rolling member 50 during the rolling operation. Thus, the curved surface film 1 can be rolled and attached to the screen 2 to be pasted with a constant downward pressure, and the situation of air bubbles caused by insufficient local adhesion force of the curved surface film 1 due to uneven downward pressure will not occur.

[0048] By providing a curved surface roller 51, the setting of the curved surface roller 51 can apply a relatively large rolling pressure to the middle part of the curved surface tempered film during the rolling process, so as to achieve the operation of exhausting air first in the middle between the curved surface tempered film and the screen 2 to be pasted, and further ensure that no air bubbles are generated during the film - pasting process.

[0049] The present utility model also provides a pulling belt 40, which can tear off the release film during the clearance fit process between the curved surface film 1 and the screen 2 to be pasted, so as to ensure that no dust is generated between the curved surface film 1 and the screen 2 to be pasted, achieving the operation of dust - free film - pasting.
