Description

Technical Field

[0001] The utility model relates to the technical field of film applicators, in particular to a film applicator with controllable rolling pressure and capable of realizing repeated rolling and film applying operations. Background Art

[0002] With the wide popularization of electronic devices such as smart phones, people's demand for protecting mobile phone screens is increasing day by day. In order to prevent the screen from being scratched or damaged, applying a film to the mobile phone has become a common operation. However, the traditional manual film applying method is not only time-consuming and laborious, but also the film applying effect is often not ideal, and problems such as bubbles and angle deviation are likely to occur. In order to improve the efficiency and quality of film applying, a mobile phone film applicator has emerged.

[0003] Existing film applicators will install a rolling wheel structure to achieve the rolling film applying method to ensure that the protective film can be closely attached to the screen. Therefore, the rolling wheel plays a key role. The early rolling devices were mainly applicable to flat mobile phone screens and could better complete the rolling operation after film applying, remove bubbles and make the protective film closely fit the screen. However, with the continuous development of mobile phone screen technology, curved screens have gradually become the mainstream of the market. While bringing a better visual experience, curved screens also pose new challenges to film applying.

[0004] It is found in actual operation that when the existing rolling devices are dealing with curved mobile phone screens, compared with flat screens, it takes a longer time to repeatedly roll to effectively remove bubbles. This is because the curved screen has different radian and height changes, and it is difficult to precisely control the rolling pressure of the traditional rolling device, and it is impossible to apply uniform pressure to all parts of the screen. In addition, in order to ensure the film applying quality, it is often necessary to perform multiple repeated rolling operations. However, some existing film applicators often have an inconvenient disassembly assembly relationship with the rolling wheel, and the rolling pressure of the rolling wheel structure cannot be adjusted. The force received during its reciprocating rolling is the same, so that the bubbles between the protective film and the screen can only be reciprocally pushed, and it is impossible to control the bubbles to gradually squeeze out in one direction. Therefore, it is necessary to propose an improved technical solution to solve the above problems. Summary of the Utility Model

[0005] The utility model aims to provide a technical solution to overcome the above deficiencies.

[0006] A film applicator with controllable rolling force and capable of repeated rolling and film applicator operations, used for attaching a protective film to a screen to be applicator, comprising a film applicator main body, a positioning groove for positioning and placing the screen to be applicator, a protective film positioning structure for positioning the protective film on the film applicator main body, so that the protective film is positioned above the positioning groove, and also comprising a rolling device, the rolling device comprising a hand-pushing main body, a rolling wheel rotatably connected to the lower end of the hand-pushing main body, and a guide slider arranged below the two ends of the hand-pushing main body, sliding parts are arranged on both sides of the film applicator main body located in the positioning groove, and long guide holes parallel to each other are penetrated on the two sliding parts, the guide slider comprises a guide part slidably connected in the guide long hole, an upper abutting part formed on the guide part and abuttable with the upper end of the sliding part, and a lower abutting part formed under the guide part and abuttable with the lower end of the sliding part, wherein the spacing between the upper abutting part and the lower abutting part is greater than the thickness of the sliding part.

[0007] Preferably, the front end of the film applicator body is extended, and the front end of the long guide hole extends to the position where the front end of the film applicator is extended.

[0008] Preferably, a mounting opening is expanded at the front end of the guide long hole, and the guide sliding block is detachably connected to the guide long hole along the mounting opening.

[0009] Preferably, the hand push body is an upwardly protruding structure, so that the upper end of the hand push body forms a protruding gripping structure, and the lower end of the hand push body forms a groove structure. The rolling wheel includes a rotating shaft member rotatably connected to both sides of the groove structure and a rolling member sleeved on the rotating shaft member, and the lower end of the rolling member is lower than the lower end of the hand push body.

[0010] Preferably, superior arc clamping holes are respectively formed on both sides of the groove-shaped structure, and both ends of the rotating shaft are clamped and matched with the superior arc clamping holes.

[0011] Preferably, the protective film positioning structure includes a release film attached to the protective film, a positioning buckle arranged on the film applicator body and located in front of the positioning groove, and a positioning column arranged on the film applicator body and located behind the positioning groove.

[0013] Preferably, a hand buckle portion is provided at the rear end of the positioning groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting the distance between the upper abutting part and the lower abutting part to be greater than the thickness of the sliding part, the rolling device can be finely adjusted in height. With this setting, when operating the rolling device to roll the protective film, the corresponding downward pressure can be applied automatically to adjust the downward pressure of the rolling wheel on the protective film. Through this operation, when rolling for the first time, a certain degree of downward pressure is applied to ensure that the protective film can be rolled and attached to the screen to be pasted. If bubbles or other phenomena occur and rolling needs to be performed again, the user can drag the rolling device back to the initial position by lifting it, and then continue to apply a certain degree of downward pressure to drag the rolling wheel to roll the protective film again. By repeating this operation until all the bubbles between the protective film and the screen to be pasted are squeezed out, the pasting operation can be completed. Therefore, through this setting, the adjustment of the rolling force when the rolling wheel rolls the protective film can be greatly improved, so that the operation of squeezing out bubbles in a specific direction can be achieved during multiple rolling operations.

Specific embodiments

[0027] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-7 , in the embodiment of the present utility model, a film applicator with controllable rolling force and capable of realizing repeated rolling and film pasting operations is used to attach a protective film to a screen to be pasted. It includes a film applicator main body 10, on which a positioning groove 11 for positioning and placing the screen to be pasted is opened. A protective film positioning structure 20 for positioning the protective film is also provided on the film applicator main body 10, so that the protective film is positioned above the positioning groove 11. When in use, after positioning and placing the screen to be pasted into the positioning groove 11 of the film applicator main body 10, the protective film is then positioned and placed above the positioning groove 11 according to the protective film positioning structure 20, so that the protective film and the screen to be pasted are positioned and matched with each other and can form a certain distance. On this basis, it is set that the film applicator further includes a rolling device 30. The rolling device 30 includes a hand-pushing main body 31, a rolling wheel 32 rotatably connected to the lower end of the hand-pushing main body 31, and guiding sliders 33 provided below both ends of the hand-pushing main body 31. Sliding portions are provided on both sides of the film applicator main body 10 at the positions of the positioning groove 11, and mutually parallel guiding long holes 12 are penetrated through both sliding portions. The guiding slider 33 includes a guiding portion 331 slidably connected in the guiding long hole 12, an upper abutting portion 332 formed on the guiding portion 331 and capable of abutting and cooperating with the upper end of the sliding portion, and a lower abutting portion 333 formed under the guiding portion 331 and capable of abutting and cooperating with the lower end of the sliding portion. Among them, the distance between the upper abutting portion 332 and the lower abutting portion 333 is greater than the thickness of the sliding portion.

[0029] The guide slider 33 is provided with a matching structure with the guide slot 12, so that the guide slider 33 can have a guide portion 331, an upper abutting portion 332 and a lower abutting portion 333, and its cross section forms a structure similar to an I-shaped structure. A sliding portion with a thickness matching is provided based on the guide slider 33, and a guide slot 12 for restricting the guide slider 33 is provided on the sliding portion, so that after the guide slider 33 cooperates with the guide slot 12, the upper abutting portion 332 and the lower abutting portion 333 cooperate with the sliding portion to limit the removal of the guide slider 33, and then the guide portion 331 cooperates with the guide slot 12 to enable the guide slider 30 to slide in a directional manner on the film applicator body 10. In addition, the spacing between the upper abutting portion 332 and the lower abutting portion 333 is provided to be greater than the thickness of the sliding portion, so that the height of the guide slider 30 can be finely adjusted. With this arrangement, when operating the rolling device 30 to roll the protective film, the corresponding downward pressure can be applied to adjust the downward pressure of the rolling wheel 32 on the protective film. With this operation, during the first rolling, a certain degree of downward pressure is applied to ensure that the protective film can be rolled and attached to the screen to be pasted. If bubbles or the like appear and the rolling operation needs to be performed again, the user can lift the rolling device 30 back to the initial position, and then continue to apply a certain downward pressure to drag the rolling wheel 32 to roll the protective film again. This reciprocating operation is performed until all the bubbles between the protective film and the screen to be pasted are squeezed out, and the film pasting operation is completed. Therefore, with this arrangement, the adjustment of the rolling pressure of the rolling wheel 32 when rolling the protective film can be greatly improved, so that the bubble can be extruded in a directional manner in multiple rolling operations.

[0030] In addition, since the rolling pressure can be adjusted, the film applicator can be used for protective films of different materials, thicknesses and hardness, as well as various types of mobile phone screens, including flat screens, curved screens, 2.5D screens, etc.; for ordinary users, the previous film applicator may require certain skills and experience to avoid problems such as bubbles and crooked application. However, this film applicator greatly reduces the difficulty of film application through the controllable rolling pressure and the convenience of repeated rolling, which significantly reduces the probability of film application failure, saves the cost of protective films and the user's time. Even users with no film application experience can easily complete high-quality film application operations.

[0031] See also Figures 1-3, in the embodiment of the present utility model, it is further proposed that the front end of the film applicator main body 10 is lengthened, and the front end of the guiding long hole 12 extends to the position where the front end of the film applicator is lengthened. Through this setting, when placing the screen or the protective film to be applied with film, the rolling device 30 can be dragged to the front end of the film applicator main body 10 without interfering with the operator's positioning of the screen and the protective film to be applied with film; an installation opening 13 is formed by expanding the front end of the guiding long hole 12, and the guiding slider 33 is detachably connected to the guiding long hole 12 along the installation opening 13; this operation facilitates the disassembly and assembly of the rolling device 30, thereby improving the flexibility of use of the rolling device 30.

[0032] Please refer to Figures 5-7 , in the embodiment of the present utility model, it is further proposed that the hand-pushing main body 31 is a structure protruding upward, so that the upper end of the hand-pushing main body 31 forms a protruding holding structure, which is convenient for the user to hold and perform dragging operations, and is also convenient for the user to apply different degrees of downward pressure. The lower end of the hand-pushing main body 31 forms a groove-like structure. The rolling wheel 32 includes a rotating shaft member 321 rotatably connected to both sides of the groove-like structure and a rolling member 322 sleeved on the rotating shaft member 321. The lower end of the rolling member 322 is lower than the lower end of the hand-pushing main body 31. This structural setting is simple and compact, and by reasonably utilizing the protruding structure, the material cost can be reduced to a certain extent.

[0033] Please refer to Figures 5-7 , in the embodiment of the present utility model, it is further proposed that excellent arc clamping holes 311 are respectively formed on both sides of the groove-like structure, and both ends of the rotating shaft member 321 are clamped and matched with the excellent arc clamping holes 311, which is convenient for the disassembly and assembly of the rolling wheel 32, so that the rolling wheel 32 with an adapted structure can be replaced according to the curved screen or the flat screen, enabling the film applicator to have a more flexible assembly method.

[0034] Please refer to Figures 1-3In the embodiment of the utility model, it is further proposed that the protective film positioning structure 20 includes a release film 21 attached to the protective film, a positioning buckle 22 arranged on the film applicator body 10 and located in front of the positioning groove 11, and a positioning column 23 arranged on the film applicator body 10 and located behind the positioning groove 11.
