Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of film pasting tools, and more particularly to a simple film pasting device with limiting and a film pasting kit. BACKGROUND

[0002] In order to protect the screen of a terminal device such as a mobile phone or a tablet, a user usually pastes a protective film such as a tempered film or a soft film on the planar surface of the terminal device, so that the touch screen is not easily scratched. In the process of pasting the film, in order to pursue the flatness of lines and to avoid air bubbles, the appearance of the terminal device is kept beautiful. Therefore, a film pasting device is usually used to assist the user in accurate positioning and film pasting, so that the film pasting effect can be improved.

[0003] Some existing film pasting devices use a film sheet positioning groove to limit the protective film. The protective film is installed in the film sheet positioning groove, the release layer of the protective film is then torn off, and the protective film is then attached to the mobile terminal. In the process of limiting the protective film by the film sheet positioning groove, the depth of the film sheet positioning groove is only slightly thicker than the thickness of the protective film, or even exactly the same as the thickness of the protective film. Therefore, in the process of tearing off the release layer, the entire protective film is easily pulled up and lifted out of the film sheet positioning groove, which causes the protective film to be out of position and leads to film pasting failure.

[0004] Therefore, the prior art still needs to be improved and developed. CONTENT OF THE INVENTION

[0044] Embodiment one

[0045] As shown in Figure 3 , Figure 4 , the present embodiment proposes a simple film applicator with limiting position, which is used for applying film to the screen of a mobile terminal. The mobile terminal in the present embodiment can be a mobile phone 10, and can also be a tablet computer, an electronic book, a smart watch and other electronic devices. For the convenience of structural description of the present embodiment, the length direction of the mobile phone 10 is taken as the length direction, the width direction is taken as the width direction, and the thickness direction is taken as the up-down direction. The parts of the film applicator in the present embodiment are described in the above direction. As shown in Figure 2 , Figure 3 , the simple film applicator with limiting position is used for bonding the protective film 20 to the screen of the mobile phone 10, and the protective film 20 can include: a film layer 21 and a tear-off release layer 22. The film layer 21 is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10, and the film layer 21 can be tempered glass. The tear-off release layer 22 is first arranged on the film layer 21 to protect the bonding surface of the film layer 21. In use, the tear-off release layer 22 is pulled away from the film layer 21, and only the film layer 21 is bonded to the surface of the screen of the mobile phone 10. The edge of the tear-off release layer 22 of the protective film 20 in the present embodiment is provided with a clamping groove 23, and the clamping groove 23 can be provided with a plurality of clamping grooves 23, which are located on at least one side of the width direction of the tear-off release layer 22.

[0046] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the main part of the film applicator includes a cover 100 which is a rectangle matching the shape of the mobile phone 10. For the convenience of structural description, the middle line of the cover 100 in the width direction is the width middle line, and the middle line in the length direction is the length middle line. The side surface of the cover 100 on which the protective film 20 is installed is the upper surface, and the opposite side surface is the lower surface. The structure is described by taking the installation of the protective film 20 on the upper part of the cover 100 as an example. The film positioning groove 110 is arranged on the upper surface of the cover 100. The first plug-in sliding film fixing structure 200 is arranged on one side of the cover 100 in the width direction, and the second plug-in sliding film fixing structure 300 is arranged on the other side of the cover 100 in the width direction. One or more first plug-in sliding film fixing structures 200 can be arranged on one side, and one or more second plug-in sliding film fixing structures 300 can be arranged on the other side. The first plug-in sliding film fixing structure 200 and the second plug-in sliding film fixing structure 300 on the side of the cover 100 form the film clamping groove 230. Specifically, the film clamping groove 230 is formed on the lower part of the first plug-in sliding film fixing structure 200 and the lower part of the second plug-in sliding film fixing structure 300, and the film clamping groove 230 on both sides in the width direction is used to clamp the two side edges of the tear-off release layer 22 of the protective film 20 in the width direction. When the film is applied, the side edge of the tear-off release layer 22 of the protective film 20 in the width direction is inserted into the film clamping groove 230 below the second plug-in sliding film fixing structure 300, and the other side edge of the tear-off release layer 22 of the protective film 20 is sleeved on the first plug-in sliding film fixing structure 200, so that the protective film 20 can be directly placed on the surface of the cover 100, and the protective film 20 is pushed in the length direction, so that the clamping groove 23 on one side of the tear-off release layer 22 of the protective film 20 in the width direction is offset from the position of the first plug-in sliding film fixing structure 200, so that the edge of the tear-off release layer 22 of the protective film 20 is clamped below the film clamping groove 230 of the first plug-in sliding film fixing structure 200, and the film layer 21 of the protective film 20 is accommodated in the film positioning groove 110 for limiting by sliding; so as to realize the limiting of the cover 100 to the protective film 20. The limiting piece 150 is arranged at the pull-out side edge of the film positioning groove 110, and the limiting piece 150 protrudes from the plane of the slot opening of the film positioning groove 110 (which can be the upper surface of the cover 100). Because when the film is applied, the tear-off release layer 22 on the protective film 20 is pulled out from one side in the length direction, so that the film layer 21 of the protective film 20 is exposed and then adhered to the mobile terminal, and then the side of the tear-off release layer 22 pulled out in the length direction is the pull-out side.

[0047] The first plug-in slide type film fixing structure 200 and the second plug-in slide type film fixing structure 300 are formed with a film clamping groove 230 on the side facing the cover 100. The protective film 20 can be slid along the length direction by being sleeved into the first plug-in slide type film fixing structure 200, so that the edge of the protective film 20 is clamped in the film clamping groove 230 and the protective film 20 is accommodated in the film positioning groove 110. The protective film 20 is limited by the inner wall of the film positioning groove 110, and the mobile terminal to be pasted with the film is limited on the outside of the protective film 20 and faces the protective film 20. When pasting the film, the tear-off release layer 22 on the protective film 20 is pulled off from the length direction of the pull-out side, so that the adhesive surface of the film pasting layer 21 of the protective film 20 is exposed and adhered to the mobile terminal. Then, during the pulling out of the tear-off release layer 22, even if the entire protective film 20 is pulled up and raised to the slot of the film positioning groove 110, the pull-out side of the film pasting layer 21 (only the film pasting layer 21 remains) of the protective film 20 is blocked by the limiting piece 150 protruding at the pull-out side edge of the film positioning groove 110, so that the film pasting layer 21 is still limited in the film positioning groove 110. Therefore, by providing the limiting piece 150, the film pasting layer 21 will not be pulled out of the film positioning groove 110 during the film tearing process, and the film pasting success rate is improved.

[0048] As shown in Figure 1 , Figure 3 further, the limiting piece 150 of the embodiment specifically includes: a limiting boss 151, the side of the limiting boss 151 facing the film positioning groove 110 is connected with the inner wall of the film positioning groove 110. In the specific structure, the upper surface of the limiting boss 151 is higher than the upper surface of the cover 100 (the plane of the slot of the film positioning groove 110), and the side wall of the limiting boss 151 can be flush with the inner wall of the film positioning groove 110, so that the wall surface of the pull-out side of the film positioning groove 110 is raised by the limiting boss 151, achieving better limiting effect.

[0049] As shown in Figure 1 , Figure 7 further, the limiting boss 151 of the embodiment is provided with one, and the one limiting boss 151 is located at the middle position of the width direction of the pull-out side edge of the film positioning groove 110. The one limiting boss 151 located in the middle extends a predetermined length in the width direction, which can block the middle of the pull-out side of the protective film 20. In addition, the length of the limiting boss 151 is not limited, which can be a longer strip shape in the width direction, or a smaller strip shape, all of which can achieve the technical effect.

[0050] It is easy to think that the limiting boss 151 can also be provided with multiple, multiple limiting boss 151 along the width direction of the film positioning groove 110 pull out the edge of the interval arrangement. The interval arrangement of the limiting boss 151 can block the protective film 20 on both sides, so that the protective film 20 is stable when abutting against the inner wall, not easy to be offset.

[0051] As shown in Figure 1 , Figure 7 Further, the height of the limiting boss 151 of the embodiment is 0.35-0.6 times the depth of the film positioning groove 110. The height of the limiting boss 151 is not too high or too low, if the limiting boss 151 is too high, the protective film 20 is not easy to press into the film slot 230, if the limiting boss 151 is too low, the blocking effect of the protective film 20 is limited. Therefore, the height of the limiting boss 151 is limited, which can make the protective film 20 easily press into the film slot 230, and also effectively block the protective film 20.

[0052] As shown in Figure 3 , Figure 5 , Figure 6As shown, further, the first plug-in sliding film piece fixing structure 200 and the second plug-in sliding film piece fixing structure 300 are both provided with a clamping step 211 on the side away from the cover body 100. Therefore, the clamping step 211 is formed on the upper part of the first plug-in sliding film piece fixing structure 200 and the upper part of the second plug-in sliding film piece fixing structure 300, and the clamping steps 211 on both sides in the width direction can enclose a terminal limiting part for accommodating and limiting the mobile terminal to be pasted with the film. By arranging the first plug-in sliding film piece fixing structure 200 and the second plug-in sliding film piece fixing structure 300 on both sides in the width direction of the cover body 100, the clamping step 211 is formed on the upper part of the first plug-in sliding film piece fixing structure 200 and the second plug-in sliding film piece fixing structure 300, and the film clamping groove 230 is formed on the lower part. When pasting the film, the edge of the tear-off release layer 22 of the protective film 20 on one side in the width direction is inserted into the film clamping groove 230 below the second plug-in sliding film piece fixing structure 300, the protective film 20 is pushed in the length direction, the clamping groove 23 on one side of the tear-off release layer 22 of the protective film 20 is offset from the position of the first plug-in sliding film piece fixing structure 200, then the edge of the tear-off release layer 22 of the protective film 20 is clamped in the film clamping groove 230, and the film pasting layer 21 of the protective film 20 is accommodated in the film piece positioning groove 110 for limiting. Then the mobile terminal to be pasted with the film is placed on the clamping step 211 on the upper part, so that the mobile terminal is limited in the terminal limiting part, and the screen of the mobile terminal faces and is opposite to the protective film 20 below. Therefore, the protective film 20 and the mobile terminal to be pasted with the film are both limited on the cover body 100, and the pasting of the film on the mobile terminal can be completed by one cover body 100 structure, so that the structure of the film pasting device is simpler, the production cost is lower, and the use is more convenient.

[0053] As Figure 3 , Figure 5 , Figure 6As shown, further, the first plug-in slide film fixing structure 200 of the embodiment specifically comprises: a first limiting column 210 and a first film clamping boss 220. The first limiting column 210 is integrally formed on the upper surface of the cover body 100 and located outside the edge of the film positioning groove 110. The first film clamping boss 220 is protruded on the inner side of the first limiting column 210 along the width direction, so that the first film clamping boss 220 extends towards the inner side of the film positioning groove 110. In the specific structure, the first film clamping boss 220 is located in the middle of the upper and lower directions of the first limiting column 210, so that the side of the first film clamping boss 220 away from the cover body 100 and the first limiting column 210 form a clamping step 211, and the side of the first film clamping boss 220 towards the cover body 100 and the surface of the cover body 100 form a film clamping groove 230. Therefore, the clamping step 211 is located above the first film clamping boss 220, and the film clamping groove 230 is located below the first film clamping boss 220. In use, by tearing the side edge of the release layer 22 of the protective film 20 into the first limiting column 210 through the clamping groove 23, the film layer 21 of the protective film 20 is placed on the upper surface of the cover body 100, and the release layer 22 of the protective film 20 is located above the film layer 21; by pushing the protective film 20 to slide along the length direction, the clamping groove 23 of the edge of the release layer 22 of the protective film 20 is misaligned with the position of the first limiting column 210, so that the edge of the release layer 22 of the protective film 20 is clamped in the film clamping groove 230, and the film layer 21 of the protective film 20 slides into the film positioning groove 110. The film positioning groove 110 is matched with the size of the film layer 21 of the protective film 20, so that the film layer 21 is limited by the film positioning groove 110 after sliding into the film positioning groove 110. Since the film layer 21 of the protective film 20 is limited in the film positioning groove 110 in the length direction and the width direction, and is limited by the first plug-in slide film fixing structure 200 in the upper and lower directions, the protective film 20 is stably installed on the cover body 100 and is not easy to loosen. Moreover, the clamping groove 23 is formed on the protective film 20, and the clamping groove 23 is misaligned with the position of the first limiting column 210 to achieve clamping by pushing, so that the installation is completed only by misaligning the clamping groove 23 with the position of the first limiting column 210, the pushing distance is short, and the installation is more convenient.

[0054] As shown in Figure 3 , Figure 4 , Figure 6 The first limiting column 210 is located at the upper part of the first film clamping boss 220 as the vertical surface of the clamping step 211, and the upper surface of the first film clamping boss 220 is as the horizontal surface of the clamping step 211. When the mobile phone 10 is placed in the terminal limiting part, the clamping steps 211 on both sides of the width direction support and limit the left and right sides of the mobile phone 10 respectively, the vertical surfaces on both sides abut against the left and right sides of the mobile phone 10 respectively, and the horizontal surfaces on both sides support the left and right edges of the screen of the mobile phone 10 respectively, so as to achieve the support and limitation of the mobile phone 10.

[0055] As Figure 1 , Figure 3 , Figure 5 shown, further, the first card film boss 220 of the embodiment away from the upper surface of the cover 100 side is provided with an inclined guide surface 221. Inclined guide surface 221 is located in the upper surface of the first card film boss 220, inclined guide surface 221 gradually close to the width center line along the direction from top to bottom. With the form of inclined downward, when the protective film 20 installation, the edge of the card slot 23 of the protective film 20 is abutted on the inclined guide surface 221, guided by the inclined guide surface 221, so that the card slot 23 is set in the outside of the first limiting column 210 to slide down smoothly, the installation process of the protective film 20 is more convenient.

[0056] As Figure 1 , Figure 3 , Figure 5 shown, further, the first card film boss 220 of the embodiment towards the card film slot 230 side, and located in the sliding direction of the protective film 20 one end is provided with the insertion inclined surface 222. In the specific structure, the direction of sliding along the length direction to make the position of the card slot 23 and the first limiting column 210 stagger is the sliding direction, then the insertion inclined surface 222 is located in the length direction of the lower surface of the first card film boss 220 sliding end, the insertion inclined surface 222 gradually close to the upper surface of the cover 100 along the sliding direction. In this way when installing the protective film 20, the length direction of the card slot 23 of the protective film 20 one side edge is abutted on the insertion inclined surface 222, guided by the insertion inclined surface 222, so that the card slot 23 slides through the card film slot 230, and the edge of the protective film 20 located outside the card slot 23 is smoothly slid into the card film slot 230, making the installation process of the protective film 20 more convenient.

[0057] As Figure 1 , Figure 3 , Figure 5 shown, further, the first card film boss 220 of the embodiment towards the card film slot 230 side, and located in the sliding direction of the protective film 20 one end is provided with the exit inclined surface 223. In the specific structure, the direction of pulling out the tear-off type layer 22 along the length direction is the sliding direction, the exit inclined surface 223 is located in the length direction of the lower surface of the first card film boss 220 sliding end, so the exit inclined surface 223 and the insertion inclined surface 222 are oppositely arranged in the length direction. And the exit inclined surface 223 gradually close to the upper surface of the cover 100 along the sliding direction, in this way when pulling out the tear-off type layer 22, the length direction of the other side edge of the card slot 23 of the tear-off type layer 22 is abutted on the exit inclined surface 223, guided by the exit inclined surface 223, so that the card slot 23 slides into the card film slot 230, and then smoothly pulls out the tear-off type layer 22. The process of pasting the protective film 20 is more convenient.

[0058] It should be noted that the first and second plug-in sliding film fixing structures 200 and 300 on both sides of the upper surface of the cover body 100 in the width direction can be the same, and the corresponding protective film 20 is provided with a clamping groove 23 on both sides in the width direction to match the plug-in sliding film fixing structures on both sides.

[0059] As shown in FIGS. 1 and 2, the first plug-in sliding film fixing structure 200 is arranged on one side of the upper surface of the cover body 100 in the width direction, and the second plug-in sliding film fixing structure 300 is arranged on the other side of the upper surface of the cover body 100 in the width direction. Figure 1 Figure 3 Figure 6 As shown in FIGS. 1 and 2, the first plug-in sliding film fixing structure 200 is arranged on one side of the upper surface of the cover body 100 in the width direction, and the second plug-in sliding film fixing structure 300 is arranged on the other side of the upper surface of the cover body 100 in the width direction.The second plug-in sliding film fixing structure 300 of the present embodiment specifically includes a second limiting column 310 and a second film clamping boss 320. The second limiting column 310 is arranged on the surface of the cover body 100, and the second film clamping boss 320 is arranged on the inner side of the second limiting column 310 in the width direction. The side of the second film clamping boss 320 away from the cover body 100 and the second limiting column 310 form a clamping step 211, and the space between the second film clamping boss 320 and the surface of the cover body 100 forms a film clamping groove 230. Therefore, the clamping step 211 is above the second film clamping boss 320, and the clamping step 211 above the second film clamping boss 320 is a mirror image symmetric structure. The film clamping groove 230 is below the second film clamping boss 320, and the other side edge of the width direction of the tear-off release layer 22 of the protective film 20 is clamped in the film clamping groove 230. The side of the second film clamping boss 320 facing the upper surface of the cover body 100 is provided with a guide inclined surface 321; the second plug-in sliding film fixing structure 300 is similar to the first plug-in sliding film fixing structure 200, but the edge of the tear-off release layer 22 matched with the second plug-in sliding film fixing structure 300 does not need to be provided with a clamping groove 23, so the second film clamping boss 320 does not need to be provided with an insertion inclined surface 222 and an exit inclined surface 223, but needs to be provided with a guide inclined surface 321 on the lower surface of the second film clamping boss 320. The guide inclined surface 321 is arranged from the lower surface to the upper surface in the direction of gradually approaching the width direction center line. In this way, when the protective film 20 is installed, the length direction edge of the tear-off release layer 22 of the protective film 20 is directly inserted into the plurality of second plug-in sliding film fixing structures 300, so that the long side of the tear-off release layer 22 is directly clamped into the second film clamping groove 230, and it is not necessary to push from the head end in the length direction, which greatly saves the installation time.​

[0060] like Figure 7 As shown, in another structure, a stacking slot 160 is provided on the side (lower surface) of the cover 100 facing away from the film positioning groove 110.

The stacking slot 160 is provided correspondingly to the first sliding film fixing structure 200 and the second sliding film fixing structure 300. For example, two or three first sliding film fixing structures 200 on one side are provided with two or three stacking slots 160, and two or three second sliding film fixing structures 300 on the other side are provided with two or three stacking slots 160. When the first sliding film fixing structure 200 and the second sliding film fixing structure 300 of the lower simple film applicator are respectively inserted into the stacking slot 160 of the upper simple film applicator, the simple film applicators stacked on top of each other are connected and stably stacked.

[0061] like Figure 7 As shown, during stacking, the top of the end of the first film-clamping protrusion 220 facing away from the cover 100 is used to insert into the stacking slot 160, and the top of the end of the second film-clamping protrusion 320 facing away from the cover 100 is also used to insert into the stacking slot 160. Since the tops of both the first film-clamping protrusion 220 and the second film-clamping protrusion are relatively protruding, they can be inserted into the stacking slot 160 of the simple film applicator above. In this way, the stacking slot 160 can accommodate the upper protruding portions of the first sliding film fixing structure 200 and the second sliding film fixing structure 300, reducing the stacking volume and facilitating production.

[0062] like Figure 7 As shown, in this embodiment, a core-pulling hole 170 is provided through the cover 100, and the core-pulling hole 170 is located below the first sliding diaphragm fixing structure 200 and the second sliding diaphragm fixing structure 300; one side of the stacking slot 160 is connected to the core-pulling hole 170. In this way, the core-pulling on the forming mold of the stacking slot 160 can be designed as a single core-pulling device with the core-pulling device of the forming first sliding diaphragm fixing structure 200, thus optimizing the structure of the forming mold.

[0063] like Figure 1 , Figure 2 , Figure 3As shown, further, the cover 100 of the embodiment also includes a stopper 130 at one end in the length direction, the stopper 130 is arranged outside the end of the diaphragm positioning groove away from the limiting member, the stopper 130 is used to limit the sliding of the protective film 20 in the length direction, and the stopper 130 is also used to limit the mobile phone 10 to be pasted in the length direction. The stopper 130 specifically includes two stopper plates arranged at intervals, the stopper plates are located outside the diaphragm positioning groove 110 in the length direction, and the sliding of the protective film 20 in the length direction is limited, so that the installation of the protective film 20 is more convenient.

[0064] As shown in Figure 1 , Figure 2 As shown, further, the cover 100 of the embodiment is provided with an upper limiting plate 120 on the pull-out side in the length direction, the upper limiting plate 120 is arranged at intervals with the surface of the cover 100 to form a pull-out opening 121. After the protective film 20 is installed on the cover 100, the pull-out side of the tear-off release layer 22 of the protective film 20 is pulled out from the pull-out opening 121, so that the user can conveniently pinch the tear-off release layer 22 exposed in the pull-out opening 121 with his hand, and the tear-off release layer 22 is conveniently torn off from the pasting film layer 21. The upper limiting plate 120 can be suspended above the cover 100 by using a whole plate, or can be arranged above the cover 100 by using left and right sides.

[0065] As shown in Figure 1 , Figure 2 As shown, further, the cover 100 of the embodiment is provided with a pressing hole 140. The pressing hole 140 is used to press the pasting film layer 21 of the protective film 20 adhered on the mobile phone 10, so that the adhesion of the pasting film layer 21 is more firm.

The tear-off release layer 22 is arranged on the pasting film layer 21 and protects the pasting film layer 21, and the tear-off release layer 22 is used to cooperate with the first plug-and-slide diaphragm fixing structure 200 and the second plug-and-slide diaphragm fixing structure 300 on the cover 100, so as to connect the protective film 20 to the cover 100. The tear-off release layer 22 is usually two layers, one layer is attached to the pasting film layer 21, and the other layer extends to the outside of the cover 100, so as to facilitate tearing.

[0068] As shown in Figure 2 , Figure 3 , Figure 6 When the cover 100 is used to paste the film, the protective film 20 is installed in the lower film clamping groove 230, the mobile phone 10 to be pasted is placed in the upper clamping step 211, the screen of the mobile phone 10 faces downward, and the tear-off release layer 22 of the protective film 20 on the cover 100 faces the screen of the mobile phone 10. The tear-off release layer 22 is pulled out from one end of the cover 100 in the length direction, and then sequentially passes through the plurality of film clamping grooves 230 and is separated from the protective film 20. At this time, the pasting film layer 21 does not move due to the blockage of the film positioning sink 110, so that the pasting film layer 21 remains in the film positioning sink 110 and faces the mobile phone 10. Then, the pasting film layer 21 is pressed from the back pressing hole 140, so that the pasting film layer 21 is attached to the screen of the mobile phone 10, and the pasting of the film becomes simpler.
