Description

Technical Field

[0001] The present application relates to the technical field of film pasting tools, and in particular to a film pasting tool with an adaptive size and a film pasting kit. Background Art

[0002] In order to protect the screens of mobile phones, tablets and other terminal devices, users usually stick a layer of film, such as tempered film, on the flat surface of the terminal device to prevent the touch screen from being scratched. During the film application process, in order to achieve smooth lines and avoid bubbles, so that the appearance of the terminal device remains beautiful, a film applicator is usually used to assist the user in precise positioning and film application, so that the film application effect can be improved.

[0003] However, in an existing type of film applicator structure, the size of the limiting cavity for mounting the mobile phone in the shell is fixed when applying the film, so it can only apply the film to a mobile phone of one specification. The same model of existing mobile phones has multiple versions, such as youth version, pro version, MAX version, etc. In order to meet the needs of applying films to multiple mobile phone versions, multiple film applicators must be designed accordingly. Therefore, a film applicator of fixed size cannot match mobile phones of different specifications when used, resulting in the problem of poor versatility of the film applicator.

DETAILED DESCRIPTION

[0062] In order to make the purpose, technical solution and advantages of the present application clearer and more specific, the present application is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0063] Embodiment 1

[0064] like Figure 1 , Figure 2 , Figure 5 As shown, this embodiment proposes that the present application provides a film applicator with an adaptive size, which is used to apply a film to the screen of a mobile terminal. The mobile terminal in this embodiment is a mobile phone 10, and can also be an electronic device such as a tablet computer, an e-book, a smart watch, etc. For the convenience of describing the structure of this embodiment, the mobile phone 10 is used as an example for explanation. The long side direction of the mobile phone 10 is the length direction, the short side direction is the width direction, and the thickness direction is the up-down direction. Figure 6 , Figure 7 , Figure 8As shown, the film applicator of the present adaptive size is used to adhere the protective film 800 to the screen of the mobile phone 10. The protective film 800 mainly includes: a film layer 810, a positioning release layer 820 and a tearing release layer 830. The film layer 810 is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10; the positioning release layer 820 can be detachably arranged on one side of the film layer 810, and the positioning release layer 820 is used to be connected to the film applicator of the present adaptive size. The tearing release layer 830 is arranged on the side of the film layer 810 away from the positioning release layer 820 and facing the mobile phone 10. When in use, the positioning release layer 820 and the tearing release layer 830 are both pulled away from the film layer 810, and only the film layer 810 is adhered to the screen surface of the mobile phone 10.

[0065] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the adaptive film applicator mainly includes: a shell 100, a movable seat 200 and a docking limiter 300. For the convenience of structural description, the shell 100 adopts a rectangular structure that matches the outline of the mobile phone 10 in the horizontal direction, and the two ends of the shell 100 in the length direction are respectively a first end 101 and a second end 102 that are opposite to each other. A receiving cavity 110 is provided in the shell 100, and the receiving cavity 110 is also set in a rectangular shape and can easily accommodate the mobile phone 10 to be filmed. The movable seat 200 is movably arranged in the receiving cavity 110 along the length direction. For example, the movable seat 200 is movably arranged at the first end 101 of the shell 100, and the movable seat 200 is moved to abut against the side of one end of the length direction of the mobile phone 10 to be filmed. The docking stopper 300 can be replaced on the housing 100. For example, the docking stopper 300 can be detachably arranged at the second end 102 of the housing 100. The detachable arrangement facilitates the replacement of the docking stopper 300. The docking stopper 300 is used to connect the plug-in port at the other end of the length direction of the mobile phone 10 to be filmed. The mobile phone 10 is limited in the width direction by the abutment of the movable seat 200 and the insertion of the docking stopper 300. The movable seat 200 is provided with a diaphragm stopper 400, which is used to connect and limit the protective film 800 so that the protective film 800 is located above the screen of the mobile phone 10. The specifications of the protective film 800 selected for mobile phones 10 of different specifications are different. These specifications are pre-designed according to the mobile phones 10 on the market, so as to facilitate the film application of the adaptive size film applicator to mobile phones 10 of different specifications.

[0066] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, in this embodiment, a self-adaptive film applicator is used. The mobile phone 10 to be filmed is placed in the accommodating cavity 110 and docked with the docking stopper 300 through the plug-in port, wherein the docking stopper 300 is configured to match the mobile phone 10 to be filmed and is installed on the housing 100; the movable seat 200 is slid and abutted against the side of one end of the length direction of the mobile phone 10, so as to support and limit the mobile phone 10 to be filmed, so that the mobile phone 10 will not move in the horizontal direction. The positioning release layer 820 of the protective film 800 is connected to the film stopper 400 on the movable seat 200, and the protective film 800 is limited by the film stopper 400 so that the protective film 800 is located above the screen of the mobile phone 10. In this way, the mobile phone 10 and the protective film 800 are both limited, so that the protective film 800 is aligned with the screen of the mobile phone 10, and then the film is applied, which ensures the accuracy of the film application process. By replacing the matching docking stopper 300 and moving the movable seat 200 to match the length of the mobile phone 10, it is possible to apply films to mobile phones 10 of different sizes, thereby improving the versatility of the film applicator. The same specification of the shell 100 structure can be used for mobile phones 10 of different specifications, which greatly reduces the design and number of molds. When converting the production of film applicators of different specifications, it is not necessary to replace large molds, thereby improving production efficiency and reducing production costs.

[0067] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, further, in this embodiment, the movable seat body 200 specifically includes: an adjustment block 210 and an inner extension support plate 220. The adjustment block 210 is slidably arranged on the first end 101 of the shell 100 along the length direction, and the adjustment block 210 forms abutting inner end surface 216 on the side facing the center of the accommodating cavity 110, and the abutting inner end surface 216 is used to abut the side of the mobile phone 10. The inner extension support plate 220 is connected to the abutting inner end surface and protrudes toward the center of the accommodating cavity 110 to abut and support the back of the mobile phone 10. By matching the abutting inner end surface and the upper surface of the inner extension support plate 220, one end of the mobile phone 10 in the length direction can be abutted and limited, so that the mobile phone 10 can be stably placed in the accommodating cavity 110 and different in the horizontal direction.

[0068] like Figure 1 , Figure 2As shown, further, the housing 100 of this embodiment is provided with a guide matching cavity 120, and guide bosses 121 extending in the length direction are provided on both side walls of the guide matching cavity 120; guide grooves 211 are provided on both side walls of the movable seat body 200, and the guide grooves 211 are sleeved on the guide matching cavity 120 so that the movable seat body 200 is located in the guide matching cavity 120 and slides in the length direction. The guide grooves 211 are sleeved on the guide bosses 121, so that the movable seat body 200 can move stably in the length direction in the guide matching cavity 120, and the mirror-symmetric structure in the width direction makes the sliding of the movable seat body 200 more stable.

[0069] like Figure 2 , Figure 7 As shown, further, the inner extension plate 220 of this embodiment is connected to the adjustment block 210 on the side away from the center of the accommodating chamber 110 to form a stop step 221. When the movable seat body 200 moves from the first end 101 toward the center away from the accommodating chamber 110, at the extreme position, the stop step 221 abuts against the inner wall of the first end 101 of the accommodating chamber 110, so that the movable seat body 200 will not continue to move, avoiding the problem of the movable seat body 200 being easy to fall off from the housing 100.

[0070] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, further, in this embodiment, an elastic part 230 is provided on the movable seat body 200, and a diaphragm stopper 400 is provided on the elastic part 230. The protective film 800 connected to the diaphragm stopper 400 is positioned above the mobile phone 10 by the elastic part 230 and is separated from the mobile phone 10 by a predetermined distance. One end of the elastic part 230 is connected to the adjustment block 210, and the other end is movably suspended. One end of the elastic part 230 that is movably provided is a movable end, and the movable end can move downward when being squeezed, and rebound upward after being free from pressure. When the positioning release layer 820 of the protective film 800 is connected to the film stopper 400, the entire protective film 800 can be positioned above the screen of the mobile phone 10 through the limiting effect of the film stopper 400, and then the tear-off release layer 830 of the protective film 800 is torn off the film layer 810. Since the protective film 800 is separated from the mobile phone 10 by a predetermined distance, the tear-off release layer 830 will contact the screen of the mobile phone 10 during the tearing process, thereby removing dust from the screen of the mobile phone 10. After the tear-off release layer 830 is torn off, the film layer 810 and the positioning release layer 820 are still positioned above the screen under the support of the movable end of the elastic part 230, thereby preventing the film layer 810 from contacting the screen too early.

[0071] like Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, further, a clearance cavity 212 is provided on the movable seat body 200, and the clearance cavity 212 can be provided in the middle position of the upper surface of the adjustment block 210. The elastic part 230 in this embodiment specifically includes: an elastic plate 231 and an inclined boss 232, the elastic plate 231 is located in the clearance cavity 212 and one end facing the center of the accommodating cavity 110 is suspended, and the inclined boss 232 is arranged on the suspended end of the elastic plate 231 and protrudes upward, so as to lift the protective film 800 and space it from the mobile phone 10 by a predetermined distance. Since one end of the elastic plate 231 is connected to the adjustment block 210 and the movable end is suspended, in the process of squeezing the inclined boss 232, elasticity is generated to cause the inclined boss 232 to descend, so that the protective film 800 is brought down and covers the screen surface of the mobile phone 10. The setting of the inclined boss 232 can prop up the protective film 800 so that the protective film 800 is separated from the mobile phone 10 by a sufficient predetermined distance. The predetermined distance serves as a dust removal space, which is sufficient for the tear-off layer 830 of the protective film 800 to be bent and then pulled out to abut against the screen of the mobile phone 10 and remove dust on the screen of the mobile phone 10.

[0072] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, further, the inclined boss 232 in this embodiment gradually protrudes in the direction toward the center of the accommodating cavity 110. Thus, the inclined boss 232 forms a triangular boss structure, so that only a small area at the top of the boss is required to lift up the positioning release layer 820 of the protective film 800, which is beneficial to the soft film characteristics of the positioning release layer 820, thereby avoiding a large area of ​​support for the positioning release layer 820, which causes the positioning release layer 820 to be difficult to deform and pressed down. The use of a triangular boss, especially a right-angled triangular inclined boss 232, makes it easier to press the entire film layer 810 onto the screen surface of the mobile phone 10 after the positioning release layer 820 is squeezed during the film application process.

[0073] like Figure 2 , Figure 5 , Figure 6 , Figure 7As shown, further, the film stopper 400 of this embodiment specifically includes: at least two first hooks 410 arranged at intervals along the width direction, and the first hook 410 is used to connect one end of the protective film 800 in the length direction. A pull hole 821 is opened on one end of the positioning release layer 820 of the protective film 800, and the first hook 410 can be hung on the first hook 410 through the pull hole 821, and the two first hooks 410 can limit the protective film 800 in the width direction, so that the protective film 800 can be aligned with the mobile phone 10 below in the width direction, and the pull hole 821 and the first hook 410 are matched and arranged. When the two are hung in place, they can be aligned with the mobile phone 10 in the length direction, so that the film can be applied. The hook of this embodiment has a hooking mouth 411, and the opening of the hooking mouth 411 is set away from the center of the accommodating cavity 110, so the hooking mouth 411 faces outward, and the hooking mouth 411 is used to facilitate the hook connection of the positioning release layer 820 of the protective film 800, so that the protective film 800 is not easy to fall off. The upper surface of the hook opening 411 is set as an inclined surface 412, and the inclined surface 412 gradually approaches the upper surface of the elastic plate 231 along the direction toward the center of the accommodating cavity 110. The upper wall of the hook opening 411 is set as the inclined surface 412, so that the outside is larger and the inside is smaller. Since the positioning release layer 820 uses a relatively soft film, it is convenient to enter the pulling hole 821 on the positioning release layer 820 from the larger opening on the outside, and use the inclined surface 412 for guidance to achieve smooth docking with the first hook 410.

[0074] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, further, in this embodiment, an arc-shaped transition step 213 is provided on the surface of the adjustment block 210, and the arc-shaped transition step 213 is located on the side of the diaphragm stopper 400 away from the center of the accommodating cavity 110; the surface of the adjustment block 210 is divided into a raised surface 214 and a sunken surface 215 by the arc-shaped transition step 213. The setting of the arc-shaped transition step 213 makes the side facing the center of the accommodating cavity 110 gradually become higher, so that the raised surface 214 below the hook opening 411 is also inclined, so that the opening outside of the hook opening 411 also has a gradual space. For the soft film, the installation of the protective film 800 is guided by the cooperation of the inclined surface 412 and the arc-shaped transition step 213, so that the positioning release layer 820 is easier to be accurately hooked on the first hook 410.

[0075] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8As shown, further, in this embodiment, a film hanging member 500 is further provided on the housing 100, and the film hanging member 500 is located at the second end 102 of the housing 100, so that the film hanging member 500 and the film piece stopper 400 are respectively arranged on both sides of the length direction of the housing 100, and the film hanging member 500 is used to connect and stop the other end of the length direction of the protective film 800. In this embodiment, by the cooperation of the first hook 410 and the film hanging member 500, the protective film 800 can be more stably stopped, so that the protective film 800 can be more stably installed above the screen of the mobile phone 10.

[0076] like Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 8 As shown, further, the film hanging member 500 of this embodiment includes a first hanging rod 510 and a second hanging rod 520, and the first hanging rod 510 and the second hanging rod 520 are respectively arranged at intervals in the width direction of the housing 100. The first hook 410 located at one end needs to move to a certain extent in the length direction, so that it can be deformed during the pressing process to make the film layer 810 adhere to the surface of the mobile phone 10. Therefore, the first hanging rod 510 and the second hanging rod 520 are matched in the direction to limit the other end of the positioning release layer 820 of the protective film 800, so that the protective film 800 can achieve a relatively stable limit in the length direction. First, hang one end of the protective film 800 on the first hook 410 through the pulling hole 821, and then put the other end of the protective film 800 on the first hanging rod 510 and the second hanging rod 520 through the limiting hole 822. Due to the limiting of the first hanging rod 510 and the second hanging rod 520, when the protective film 800 is straightened along the length direction, the protective film 800 can be more stably limited in the length direction, making the film-sticking process more precise.

[0077] like Figure 1 , Figure 2 , Figure 5 As shown, further, the cross-sectional shapes of the first hanging rod 510 and the second hanging rod 520 of this embodiment are different. For example, the first hanging rod 510 is cylindrical, and the second hanging rod 520 is square. Thus, a foolproof design is achieved, and it is easy to match the corresponding protective film 800, avoiding confusion between the films for users, and facilitating use for users.

[0078] like Figure 3 , Figure 4 , Figure 6 , Figure 7As shown, further, the housing 100 of this embodiment is movably connected with a roller assembly 600 along the length direction, and the roller assembly 600 squeezes the protective film 800 by moving along the length direction to adhere to the screen of the mobile phone 10. After the tear-off layer 830 of the protective film 800 is pulled out, the user can directly press the protective film 800 to stick the film layer 810 on the protective film 800 on the mobile phone 10, or use the roller assembly 600 to press. Using the roller assembly 600 to press makes the film layer 810 stable under pressure, so that the film sticking effect is better.

[0079] like Figure 3 , Figure 4 , Figure 6 As shown, further, the roller assembly 600 of this embodiment includes a rolling frame 610 and a rolling roller 620, the rolling frame 610 has edge plates 611 located on both sides in the width direction, and the rolling roller 620 is rotatably arranged on the rolling frame 610 and has a pressing outer wall, and the pressing outer wall matches the outer contour of the mobile phone 10. For example, the pressing outer wall can be cylindrical, so that it can be used for film application on a straight-screen mobile phone 10. It can also be grooved, so that it can be used for film application on a curved mobile phone 10.

[0080] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, further, rolling guide grooves 613 are provided at both ends of the rolling frame 610 of this embodiment, and the rolling guide grooves 613 are opened on the edge plate 611; the outer wall of the housing 100 is provided with a guide bar 130, which protrudes from the side of the housing 100 in the width direction and extends in the length direction. The rolling frame 610 is slidably connected to the housing 100 through the cooperation of the rolling guide grooves 613 and the guide bar 130. The rolling guide grooves 613 and the guide bar 130 cooperate to form a guide structure, so that the rolling frame 610 can slide stably along the length direction of the housing 100. During the sliding process of the rolling frame 610, the rolling roller 620 is brought to press down the protective film 800, so that the film layer 810 of the protective film 800 is adhered to the screen of the mobile phone 10.

[0081] like Figure 3 , Figure 4 As shown, further, in order to facilitate the assembly connection between the rolling frame 610 and the housing 100, an assembly hook 612 is provided at the lower end of the edge plate 611, and a rolling guide groove 613 is formed at the bend of the assembly hook 612. During assembly, the assembly hook 612 can be deformed during the extrusion process with the guide bar 130, so that the guide bar 130 is squeezed into the rolling guide groove 613 to achieve connection.

[0082] like Figure 2 , Figure 5 , Figure 6 , Figure 7 As shown, further, the upper surface of the first hook 410 is set as an arc surface, and the arc surface includes a guide arc surface 420 that gradually descends in the direction away from the center of the accommodating cavity 110. Since the guide arc surface 420 gradually concave toward the first end 101, the downward insertion of the protective film 800 can be guided during the process of hanging the protective film 800 on the first hook 410, so that the protective film 800 can slide into the hook opening 411 more smoothly. In addition, during the movement of the rolling pressure roller 620, the guide arc surface 420 is in smooth contact with the surface of the rolling pressure roller 620, so that the rolling pressure roller 620 can gradually press down the elastic part 230 in the process of applying downward pressure to the elastic part 230, so that the downward pressing process of the elastic part 230 is smoother and less likely to damage the elastic part 230.

[0083] When the elastic member returns to its original position after being squeezed by the rolling roller 620, it pushes the positioning release layer 820 on the protective film 800, so that the positioning release layer 820 is slowly separated from the film layer 810 adhered to the screen, thereby achieving automatic shedding of the positioning release layer 820, making the film pasting process more convenient.

[0084] like Figure 1 , Figure 2 , Figure 5 As shown, further, in this embodiment, an elastic extrusion piece 140 is provided on at least one inner wall of the accommodating cavity 110 in the width direction, and the elastic extrusion piece 140 is used to abut against the side of the mobile phone 10 in the width direction. When the mobile phone 10 is positioned in the length direction, it is only centered in the width direction by plugging the docking limiter 300, and the mobile phone 10 is easy to shake in the accommodating cavity 110. By providing the elastic extrusion piece 140, a certain supporting force can be applied to the side wall in the width direction of the mobile phone 10, so that the side of the mobile phone 10 in the width direction is also abutted, and it is not easy to shake during the film application process. Since the elastic effect of the elastic extrusion piece 140 leaves enough adjustable space, it can adapt to mobile phones 10 of different widths for positioning.

[0085] like Figure 1 , Figure 2 , Figure 5 As shown, further, the elastic extrusion member 140 in this embodiment includes an elastic pressing plate 141, one end of which is fixedly arranged on the inner wall of the accommodating cavity 110, and the other end of which is tilted and movably arranged toward the center of the accommodating cavity 110. The elastic pressing plate 141 can generate a relatively stable deformation, and the tilted arrangement can make the deformation amount large, so that the width adjustment range is large, and more mobile phones 10 can be adapted.

[0086] like Figure 5 , Figure 6 , Fig.10As shown, further, a dust cover 700 is hinged at one end of the length direction of the housing 100 in this embodiment, and the dust cover 700 opens or covers the opening of the accommodating cavity 110 by rotating. The accommodating cavity is opened by flipping the dust cover 700, so that the mobile phone 10 and the protective film 800 can be installed in the housing 100. When applying the film, the dust cover 700 is flipped over to cover the accommodating cavity, so as to avoid the external dust from entering the screen of the mobile phone 10 during the film application process, resulting in dust and poor film application effect. The dust cover 700 is provided with a clearance opening 710 for exposing the roller assembly 600 on both sides in the width direction, and the edge plate 611 passes through the clearance opening 710, which will not interfere with the movement of the roller assembly 600. A pulling portion 614 is protruding on the upper surface of the roller frame, and a guide strip 130-shaped opening is provided on the upper surface of the dust cover 700 to expose the pulling portion 614 of the roller assembly 600. The pulling portion 614 moves in the opening of the guide strip 130, and can guide the user to move from one side to the other side in the length direction, so as to facilitate the discharge of gas during the film application process and avoid the generation of bubbles.

[0087] like Figure 5 , Figure 6 , Fig.10 As shown, further, the dust cover 700 in this embodiment is provided with a tearing opening 730 on one end in the length direction away from the movable base body 200. The tearing opening 730 is used to pull out the tearing release layer 830 of the protective film 800. The tearing release layer 830 of the protective film 800 extends from the tearing opening 730 to facilitate the user to hold it, so that the detached tearing release layer 830 is moved out of the tearing opening 730 to expose the film layer 810 on the protective film 800 and align it with the screen of the mobile phone 10 below.

[0088] like Figure 1 , Figure 5 , Figure 6 , Figure 8 , Fig. 9As shown, further, a docking pin 740 is provided on one end of the dust cover 700 away from the movable seat body 200 in the length direction, and a docking step 150 is correspondingly provided on the housing 100. The dust cover 700 covers the housing 100 by engaging the docking pin 740 with the docking step 150. The docking step 150 is located at the second end 102 of the housing 100, and the docking pin 740 cooperates with the docking step 150, so that after the dust cover 700 is covered, the second end 102 of the housing 100 can be limited, so that the dust cover 700 is not easy to loosen after being covered. Specifically, a barb 741 is provided on the inner side of the docking pin 740, and a groove 151 is correspondingly provided on the outer wall of the docking step 150. When the docking pin 740 is inserted into the docking step 150, the barb 741 can be hooked into the slot 151, so that the dust cover 700 and the housing 100 are more stably connected, and the dust cover 700 will not loosen during the movement of the roller assembly 600. This provides a stable guide for the movement of the roller assembly 600 and prevents it from being separated from the housing 100. This prevents dust from entering and shaking that may cause film application failure.

[0089] like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, further, a plug-in slot 160 is provided on one end of the accommodating cavity 110 that is away from the movable seat body 200 in the length direction, and the plug-in slot 160 is located at the middle position in the width direction of the accommodating cavity 110. The docking limiter 300 includes: a docking card block 310 and a plug connector 320. The docking card block 310 is embedded in the plug-in slot 160, and the plug connector 320 is connected to the docking card block 310 and protrudes toward the accommodating cavity 110. The plug connector 320 is used to be plugged into the plug port of the mobile phone 10. The plug connector 320 can be a structure that docks with the type-c port of the mobile phone 10, or a structure that docks with the port of the Apple mobile phone 10, or a structure that docks with other different types of ports.

[0090] like Figure 2 As shown, further, the plug slot 160 is a dovetail slot, and the plug connector 320 is matched with the dovetail slot. The dovetail shape is not only more accurate in positioning after installation, but also easy to install and reduce the difficulty of film pasting.
