Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of film pasting devices, and particularly relates to a film pasting device. BACKGROUND

[0002] At present, mobile phones have become one of important communication tools for people, but the screens of mobile phones are easily scratched in use, which affects the display effect and aesthetic appearance of the screens of mobile phones. Therefore, people usually paste a layer of transparent protective film on the screens of mobile phones to protect the screens from being scratched. In order to realize accurate positioning of the protective film and the screen of the mobile phone, a film pasting auxiliary device is usually used to assist in pasting the film. The film pasting auxiliary device is fixed with the protective film, and the film pasting auxiliary device and the protective film are accurately positioned before leaving the factory. When used, the user places the mobile phone in the film pasting auxiliary device, so that the protective film is more easily aligned with the screen of the mobile phone.

[0003] However, the film pasting auxiliary device can only be used once. After the protective film is pasted on the mobile phone, the film pasting auxiliary device loses its function, which is relatively wasteful. CONTENT OF THE INVENTION

[0004] The embodiment of the present application provides a film pasting device. A user can install a protective film on a film pasting auxiliary device and align the protective film with the film pasting auxiliary device by himself, so as to facilitate repeated film pasting of the user and improve the utilization rate of the film pasting auxiliary device.

[0005] In a first aspect, the embodiment of the present application provides a film pasting device. The film pasting device comprises a base, a cover, a protective film, a first positioning column and a second positioning column. The base is used for fixing a device to be pasted with a film. The cover is connected with the base. The cover is provided with a first positioning hole and a second positioning hole. The protective film has a first connecting part and a second connecting part. The first connecting part and the second connecting part are detachably connected with the inner surface of the cover. The first connecting part is provided with a third positioning hole. The second connecting part is provided with a fourth positioning hole. The first positioning column is plug-pullably arranged in the first positioning hole and the third positioning hole, so that the first positioning hole is aligned with the third positioning hole. The second positioning column is plug-pullably arranged in the second positioning hole and the fourth positioning hole, so that the second positioning hole is aligned with the fourth positioning hole.

[0006] Beneficial effects: In this embodiment, the user can simultaneously insert and cooperate with the first positioning post and the first positioning hole and the third positioning hole to align the first positioning hole and the third positioning hole, and simultaneously insert and cooperate with the second positioning post and the second positioning hole and the fourth positioning hole to align the second positioning hole and the fourth positioning hole. By limiting the two parts on the protective film, the protective film is aligned with the top cover. Since the first connecting part and the second connecting part are detachably connected to the top cover, the user can fix the first connecting part and the second connecting part to the top cover. That is, the user can repeatedly and accurately fix the protective film to the top cover so as to apply the film multiple times using the film application device. Attached Figure Description

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0017] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly.

[0018] In addition, the description such as "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0019] In the present application, unless otherwise specifically defined and limited, the terms "connection", "fixation" and the like should be understood in a broad sense, for example, "fixation" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be direct connection, or indirect connection through intermediate medium; can be internal connection of two elements or interaction relationship between two elements, unless otherwise specifically limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0020] In addition, the technical solutions among various embodiments of the present application can be combined with each other, but it must be based on the implementation by the ordinary skilled in the art, and when the combination of technical solutions appears contradictory or unimplementable, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0021] In the related art, the film pasting auxiliary device and the protective film are precisely aligned by equipment before leaving the factory. After the protective film is used, the user usually has difficulty in precisely aligning the new protective film with the film pasting auxiliary device by himself, so the film pasting auxiliary device cannot be reused.

[0022] As shown in Figure 1 and Figure 2 The first aspect of the embodiments of the present application provides a film pasting device 100, which is used for pasting a film on a mobile phone, a tablet computer or the like film pasting equipment 200. The film pasting device 100 comprises a base 110, an upper cover 120, a protective film 130, a first positioning column 140 and a second positioning column 150.

[0023] The base 110 is used for fixing the film pasting equipment 200. Optionally, a limiting groove 110b is arranged on the base 110, which is used for accommodating the film pasting equipment 200 and limiting cooperation with the film pasting equipment 200. That is, the film pasting equipment 200 can be accommodated in the limiting groove 110b, and the film pasting equipment 200 cannot shake in the limiting groove 110b, so as to ensure the assembly precision of the film pasting equipment 200 and the base 110.

[0024] The upper cover 120 is connected with the base 110. The upper cover 120 can be covered on the base 110 or lifted off from the base 110. Exemplarily, the upper cover 120 can rotate relative to the base 110. The connection mode of the upper cover 120 and the base 110 can be integrated connection, or the upper cover 120 and the base 110 can be detachably arranged. When the upper cover 120 is covered on the base 110, the upper cover 120 and the base 110 are precisely aligned. The protective film 130 is arranged on the upper cover 120, and the protective film 130 and the upper cover 120 are precisely aligned. When the upper cover 120 is covered on the base 110, the protective film 130 on the upper cover 120 and the film pasting equipment 200 in the base 110 can be precisely aligned, so as to facilitate the user to paste the film. That is, the upper cover 120 and the base 110 as a whole can constitute a film pasting auxiliary device. The film pasting auxiliary device can align the protective film 130 with the screen of the film pasting equipment 200, so as to reduce the difficulty of pasting the film.

[0025] The protective film 130 has a first connecting portion 135 and a second connecting portion 136, both of which are detachably connected with the inner surface of the upper cover 120, so that the protective film 130 can be detached from the upper cover 120, or the protective film 130 can be reinstalled on the upper cover 120, to facilitate the user to replace the protective film 130 by himself.

[0026] The upper cover 120 is provided with a first positioning hole 120a and a second positioning hole 120b, the first connecting portion 135 is provided with a third positioning hole 135a, and the second connecting portion 136 is provided with a fourth positioning hole 136a. The first positioning column 140 is plug-in arranged in the first positioning hole 120a and the third positioning hole 135a, so that the first positioning hole 120a and the third positioning hole 135a are aligned. Illustratively, the first positioning column 140 can be inserted into the first positioning hole 120a first, and then the third positioning hole 135a is aligned with the first positioning column 140 and is inserted and connected, so that the third positioning hole 135a and the first positioning hole 120a are aligned. Alternatively, the first positioning column 140 can be inserted into the third positioning hole 135a first, and then the first positioning column 140 is inserted into the first positioning hole 120a, so that the third positioning hole 135a and the first positioning hole 120a are aligned. Alternatively, the first positioning hole 120a and the third positioning hole 135a can be roughly aligned first, and then the first positioning column 140 is inserted into the first positioning hole 120a and the third positioning hole 135a, so that the third positioning hole 135a and the first positioning hole 120a are aligned in the process of insertion.

[0027] Similarly, the second positioning column 150 is plug-in arranged in the second positioning hole 120b and the fourth positioning hole 136a, so that the second positioning hole 120b and the fourth positioning hole 136a are aligned. Illustratively, the second positioning column 150 can be inserted into the second positioning hole 120b first, and then the fourth positioning hole 136a is aligned with the second positioning column 150 and is inserted and connected, so that the fourth positioning hole 136a and the second positioning hole 120b are aligned. Alternatively, the second positioning column 150 can be inserted into the fourth positioning hole 136a first, and then the second positioning column 150 is inserted into the fourth positioning hole 136a, so that the fourth positioning hole 136a and the second positioning hole 120b are aligned. Alternatively, the second positioning hole 120b and the fourth positioning hole 136a can be roughly aligned first, and then the second positioning column 150 is inserted into the second positioning hole 120b and the fourth positioning hole 136a, so that the fourth positioning hole 136a and the second positioning hole 120b are aligned in the process of insertion.

[0028] By first aligning the first positioning hole 120a with the third positioning hole 135a and the second positioning hole 120b with the fourth positioning hole 136a, and then fixing the first connecting part 135 and the second connecting part 136 to the inner surface of the upper cover 120, the upper cover 120 and the protective film 130 are accurately aligned and fixed, so that the user can replace the new protective film 130 by himself.

[0029] In this embodiment, the user can align the first positioning hole 120a with the third positioning hole 135a by inserting the first positioning column 140 into the first positioning hole 120a and the third positioning hole 135a, and align the second positioning hole 120b with the fourth positioning hole 136a by inserting the second positioning column 150 into the second positioning hole 120b and the fourth positioning hole 136a. Since the two positions on the protective film 130 are limited, the protective film 130 is aligned with the upper cover 120. Since the first connecting part 135 and the second connecting part 136 are detachably connected to the upper cover 120, the user can fix the first connecting part 135 and the second connecting part 136 to the upper cover 120, that is, the user can accurately fix the protective film 130 on the upper cover 120 for multiple times to use the film pasting device 100 for multiple times.

[0030] In addition, since the first positioning column 140 and the second positioning column 150 can be inserted and detached, the film pasting device 100 is more flexible in terms of selling mode. For example, the base 110, the upper cover 120 and the protective film 130 can be sold as a whole. In addition, the protective film 130 can be sold separately, and the first positioning column 140 and the second positioning column 150 can be sold separately. Therefore, for some users who only need to paste the film once, they can choose to purchase only the base 110, the upper cover 120 and the protective film 130. For users who need to paste the film multiple times, they can choose to purchase the first positioning column 140, the second positioning column 150 and multiple protective films 130 separately, so as to meet the needs of different users and reduce the purchase cost of the users.

[0031] As shown in FIG. 1, Figure 2 In some embodiments, the first positioning hole 120a and the second positioning hole 120b are arranged at both ends of the length direction LL of the protective film 130, that is, the distance between the first positioning hole 120a and the second positioning hole 120b is relatively far, so as to improve the positioning accuracy between the protective film 130 and the upper cover 120.

[0032] As shown in FIG. 1, Figure 2As shown in the drawings, in some embodiments, the third positioning hole 135a and the fourth positioning hole 136a are arranged at the two ends of the length direction LL of the upper cover 120, and the third positioning hole 135a and the fourth positioning hole 136a are far apart, so that the distance between the first positioning hole 120a and the second positioning hole 120b is relatively far, so as to improve the positioning precision between the protective film 130 and the upper cover 120.

[0033] As shown in the drawings, in some embodiments, the diameter of the first positioning column 140 is the same as that of the first positioning hole 120a and the third positioning hole 135a, so that the fitting precision of the first positioning column 140 and the first positioning hole 120a and the third positioning hole 135a is high, thereby improving the positioning precision of the protective film 130 relative to the upper cover 120. Moreover, since the diameters of different parts of the first positioning column 140 are consistent, the production of the first positioning column 140 is relatively simple, and the cost is relatively low. Figure 2

[0034] Of course, the diameters of the first positioning hole 120a and the third positioning hole 135a can be different, and at this time, the first positioning column 140 can include a first section and a second section with different diameters, the first section is inserted and fitted with the first positioning hole 120a, and the second section is inserted and fitted with the second positioning hole 120b, so that the sizes of the first positioning hole 120a and the third positioning hole 135a can be flexibly set.

[0035] As shown in the drawings, in some embodiments, the diameter of the second positioning column 150 is the same as that of the second positioning hole 120b and the fourth positioning hole 136a, so that the fitting precision of the second positioning column 150 and the second positioning hole 120b and the fourth positioning hole 136a is high, thereby improving the positioning precision of the protective film 130 relative to the upper cover 120. Moreover, since the diameters of different parts of the second positioning column 150 are consistent, the production of the second positioning column 150 is relatively simple, and the cost is relatively low. Figure 2 Of course, the diameters of the second positioning hole 120b and the fourth positioning hole 136a can be different, and at this time, the second positioning column 150 can include a third section and a fourth section with different diameters, the third section is inserted and fitted with the second positioning hole 120b, and the fourth section is inserted and fitted with the fourth positioning hole 136a, so that the sizes of the second positioning hole 120b and the fourth positioning hole 136a can be flexibly set.

[0036] In some embodiments, the first positioning column 140 is in interference fit with the first positioning hole 120a and the second positioning hole 120b, and the first positioning column 140 is closely fitted with the upper cover 120 and the first connecting part 135, that is, the first connecting part 135 is not easy to fall off from the first positioning column 140, so that the first positioning column 140 can play a role in fixing the protective film 130.

[0037]

[0038] ​​The second positioning post 150 is in interference fit with the second positioning hole 120b and the fourth positioning hole 136a, and the second positioning post 150 is in close fit with the upper cover 120 and the second connecting part 136, that is, the second connecting part 136 is not easy to fall off from the second positioning post 150, so that the second positioning post 150 can play a role in fixing the protective film 130.

[0039] As shown in the drawings, in some embodiments, the first positioning post 140 and the second positioning post 150 have the same diameter, that is, the first positioning post 140 and the second positioning post 150 can be mutually universal, so as to further save the production cost. Alternatively, the first positioning post 140 and the second positioning post 150 have different diameters, so that the first positioning post 140 and the second positioning post 150 have the effect of preventing the protective film 130 from being installed in reverse. Figure 2

[0040] In some embodiments, at least one end of the first positioning post 140 is tapered, that is, at least one end of the first positioning post 140 is sharp, so as to facilitate the first positioning post 140 to be inserted into the first positioning hole 120a and the third positioning hole 135a. Similarly, at least one end of the second positioning post 150 is tapered, that is, at least one end of the second positioning post 150 is sharp, so as to facilitate the second positioning post 150 to be inserted into the second positioning hole 120b and the fourth positioning hole 136a.

[0041] In some embodiments, the first positioning post 140 can have a regular shape or an irregular shape, and the second positioning post 150 can have a regular shape or an irregular shape, which is not limited herein. The first positioning post 140 and the second positioning post 150 can also have a hollow cylindrical structure. If the positioning post has a cylindrical structure, the diameter mentioned herein refers to the outer diameter.

[0042] ​In some embodiments, the first connecting part 135 and the second connecting part 136 are both bonded with the inner surface of the upper cover 120. For example, the first connecting part 135 and the second connecting part 136 are provided with adhesive towards the surface of the upper cover 120, and the first connecting part 135 and the second connecting part 136 are bonded with the inner surface of the upper cover 120 by the adhesive. Alternatively, the first connecting part 135 and the second connecting part 136 are both connected with the inner surface of the upper cover 120 by adsorption. The first connecting part 135 and the second connecting part 136 are usually plastic films. The inner surface of the upper cover 120 is usually flat, so the plastic film can be attached to the inner surface of the upper cover 120, and the air between the plastic film and the inner surface of the upper cover 120 is squeezed out, so that the plastic film is adsorbed with the inner surface of the upper cover 120 (similar to the principle of mobile phone film). Of course, the connection between the first connecting part 135 and the upper cover 120 can be a combination of bonding and adsorption connection, and the connection between the second connecting part 136 and the upper cover 120 can be a combination of bonding and adsorption connection. When the user fixes the first connecting part 135 and the second connecting part 136 to the inner surface of the upper cover 120, the user only needs to press the first connecting part 135 and the second connecting part 136, which is relatively simple to operate.

[0043] As shown in Figure 3 and Figure 4 In some embodiments, the film device 100 further comprises a connecting piece 160, the connecting piece 160 comprises a first rotating part 161 and a second rotating part 162 connected with the first rotating part 161, the first rotating part 161 rotates relative to the second rotating part 162, one end of the first rotating part 161 away from the second rotating part 162 is connected with the upper cover 120, and one end of the second rotating part 162 away from the first rotating part 161 is connected with the base 110, so that the upper cover 120 rotates relative to the base 110 through the connecting piece 160. Compared with the rotating cooperation mode of the rotating shaft and the rotating hole, there is no gap cooperation between the second rotating part 162 and the first rotating part 161, so the precision is relatively high. Optionally, a crease can be arranged at the connection between the first rotating part 161 and the second rotating part 162, so that the connecting piece 160 is bent at a fixed position. Optionally, the connection between the first rotating part 161 and the second rotating part 162 can be thinned to facilitate folding. Optionally, the material of the connecting piece 160 can be polypropylene, which has excellent flexibility and bending fatigue life, so that the connecting piece 160 can withstand multiple bending. Optionally, the first rotating part 161 and the second rotating part 162 can be connected by a rotating shaft. Optionally, the upper cover 120, the connecting piece 160 and the base 110 can be integrally formed; optionally, the connecting piece 160 can be integrally formed with the upper cover 120 or the base 110, thereby reducing the assembly process and saving costs.

[0044] As shown in Figure 5 andFigure 6 As shown, in some embodiments, the protective film 130 includes a positioning film 131, a screen film 132, a dust removal film 133, and a pull strip 134. The positioning film 131 has a first connecting portion 135 and a second connecting portion 136. The positioning film 131 can position the entire protective film 130 and also protect the screen film 132.

[0045] The screen protector 132 is attached to the positioning film 131. The screen protector 132 is used to attach to the device 200 to be protected, so as to protect the screen. The screen protector 132 can be tempered glass or plastic film.

[0046] The dust removal film 133 is attached to the surface of the screen film 132 away from the positioning film 131, and the dust removal film 133 can protect the screen film 132.

[0047] The pull strip 134 is connected to one end of the dust removal film 133 and extends to the other end of the dust removal film 133. When the pull strip 134 is pulled, the dust removal film 133 is peeled off from the screen film 132. The dust removal film 133 can wipe and absorb the dust on the screen of the device 200 to be covered, thereby removing the dust from the screen of the device 200 to be covered.

[0048] Optionally, the pull strip 134 and the dust removal membrane 133 are integrally formed, thereby giving the pull strip 134 and the dust removal membrane 133 high structural strength, making it less likely to break when stretched, and also facilitating manufacturing.

[0049] like Figure 2 As shown, in some embodiments, the protective film 130 further includes an adhesive portion 137 connected between the first connecting portion 135 and the second connecting portion 136. The adhesive portion 137 may be composed of a portion of the screen film 132, a portion of the positioning film 131, and a portion of the dust removal film 133. The film application device 100 also includes an air venting strip 170 and a support pad 180. The air venting strip 170 is disposed between the inner surface of the upper cover 120 and the adhesive portion 137, and the support pad 180 is also disposed between the inner surface of the upper cover 120 and the adhesive portion 137. The air venting strip 170 can be integrally formed with the upper cover 120, thereby saving manufacturing steps, or the air venting strip 170 can be bonded to the upper cover 120, so that the material of the air venting strip 170 can be different from the material of the upper cover 120. For example, the air venting strip 170 can be made of soft foam to cause pressure damage to the adhesive portion 137 or the film application device 200. The support pad 180 can be integrally formed with the top cover 120, thereby saving manufacturing steps, or the support pad 180 can be bonded to the top cover 120, so that the material of the exhaust strip 170 can be different from that of the top cover 120. For example, the exhaust strip 170 can be made of soft rubber.

[0050] When the top cover 120 is placed on the base 110, the venting strip 170 can press the bonding portion 137 tightly, so that the bonding portion 137 is in close contact with the screen of the device 200 to be coated with the film. This allows the dust removal film 133 to come into contact with the screen of the device 200 to be coated with the film when the pull strip 134 is pulled, resulting in a better dust removal effect. Optionally, the venting strip 170 is located in the middle area of ​​the bonding portion 137. After the dust removal film 133 is peeled off from the screen film 132, the screen film 132 is bonded to the screen of the device 200 to be coated with the film. The venting strip 170 can press the middle area of ​​the screen film 132, which helps to expel air bubbles between the screen film 132 and the screen of the device 200 to be coated with the film from the center to the surrounding area.

[0051] Support pads 180 are disposed on the outer edge of the bonding portion 137. Since the venting strip 170 is disposed in the middle area of ​​the bonding portion 137, the periphery of the bonding portion 137 is not effectively supported, and the bonding portion 137 may wobble due to unstable support. The support pads 180, disposed on the outer edge of the bonding portion 137, can provide support for the bonding portion 137, reduce the wobble of the bonding portion 137, and make the bonding portion 137 more stable. Optionally, there are four support pads 180, and the four support pads 180 are respectively disposed at the four corners of the bonding portion 137.

[0052] like Figure 7 As shown, in some embodiments, the upper cover 120 has a fixed end connected to the base 110 and a free end away from the fixed end. A limiting hole 120c is provided on the side wall of the free end of the upper cover 120. The pull strip 134 extends to the other end of the dust removal membrane 133 and passes through the limiting hole 120c. The limiting hole 120c can limit the pull strip 134 to a certain extent, so that the pull strip 134 and the dust removal membrane 133 are kept as parallel as possible, thereby pulling out the dust removal membrane 133 in a more effortless manner and minimizing the risk of the protective membrane 130 shifting due to excessive force.

[0053] like Figure 7As shown, in some embodiments, the upper cover 120 is provided with a limiting part 121, and the base 110 is provided with a mating part 111. When the upper cover 120 is placed on the base 110, the limiting part 121 and the mating part 111 engage in a limiting fit, thereby fixing the upper cover 120 relative to the base 110, and the protective film 130 abuts against the device 200 to which the film is to be applied. For example, the limiting part 121 can be a slot, and the mating part 111 can be a protrusion; or the limiting part 121 can be a protrusion, and the mating part 111 can be a slot. Compared to the user continuously pressing the upper cover 120 with their hand, the locking of the upper cover 120 relative to the base 110 by the limiting part 121 and the mating part 111 can keep the force between the protective film 130 and the screen of the device 200 to be applied constant and appropriate. When the user pulls the pull strip 134, it will not be too tight, making it difficult to pull out, nor too loose, resulting in poor dust removal effect.

[0054] like Figure 7 As shown, in some embodiments, a groove 110a is provided on the side wall of the base 110. The groove 110a is used to facilitate the user to remove the film-applying device 200 from the base 110. Correspondingly, a protrusion 122 is provided on the side wall of the top cover 120. The protrusion 122 is adapted to the groove 110a. When the top cover 120 is placed on the base 110, the protrusion 122 and the groove 110a can fit together, thereby making the film-applying device 100 well sealed and minimizing the entry of dust into the interior of the film-applying device 100 during film application.
