Description

Electronic product protection film external member

The technical field is as follows:

the utility model relates to a protection film product technical field refers in particular to an electronic product protection film external member that is used for electronic equipment such as cell-phone, panel computer.

Background art:

electronic equipment with a touch screen is an essential product in life of people, and in order to protect the screen of the electronic equipment and prevent the screen from scratching, a film is generally pasted on the surface of the screen. The current protective film mostly adopts the protective film of electronic products. As shown in fig. 1, the current protective film for electronic products is usually a kit when sold, which includes: the protective film 41 and the release film 42 and the protective plate 43 respectively attached to the upper and lower surfaces of the protective film 41, the surface of the release film 42 attached to the protective film 41 is coated with a first adhesive layer 420, and the surface of the protective film 41 attached to the protective plate 43 is coated with a second adhesive layer 410. The protective film 41 is made of a specially processed tempered glass material or a specially processed plastic material, and has a smooth surface (upper surface) and a sticky surface (lower surface), where the sticky surface is the second adhesive layer 410 coated on the surface of the protective film 41 and is used for adhering to a screen of an electronic device. When the user uses the device, the user directly carries out touch screen operation on the smooth surface.

The release film 42 and the protection plate 42 are for protecting the upper and lower surfaces of the protection film 41. Therefore, the three parts are attached at one time to form an electronic product protective film kit for sale. In use, application is usually accomplished by means of a film applicator. The conventional film sticking device usually has a plastic frame body corresponding to the external shape of the electronic device, and the inner surface of the film sticking device is usually provided with a positioning adhesive (or coated with an adhesive). When in use, the whole electronic product protective film suite is placed in the film sticking device, and the whole electronic product protective film suite is connected and positioned in the film sticking device through the positioning adhesive tape, wherein the protective plate 43 is positioned at the lowest side. Then, the protection plate 43 is uncovered, and the side of the protection film 41 with the second adhesive layer 410 is exposed; and then, the whole film sticking device is buckled on the electronic equipment from top to bottom for sticking. After the bonding, the film applicator is removed, and the release film 42 is peeled off from the surface of the protective film 41.

Because the second adhesive layer 410 of the protective film 41 has a self-adhesive property, after a part of the protective film 41 is attached to the screen of the electronic device, even if no external force is applied, the attachment area will expand outwards continuously under the action of its own material stress, gravity and the like until the whole attachment is realized. Due to the characteristics of the protective film, when a user pastes the film, bubbles can be left in the pasted protective film due to carelessness, and the protective film is difficult to remove the bubbles through traditional defoaming means such as extrusion and can only be pasted again. Therefore, in the attaching process, an oblique attaching method is generally adopted: when the protective film is attached, a certain inclination exists between the protective film and the screen of the electronic equipment, one end of the protective film is aligned with one end edge of the screen of the electronic equipment, then the protective film at the end is attached to the end part of the screen and is adhered, then the protective film is released, under the characteristic effects of self weight and self adhesion of the protective film, the protective film is gradually attached to the other end along the attached end, and in the attaching process, air is automatically discharged to an area which is not attached until the whole protective film of the electronic product is completely attached to the screen of the mobile phone.

At present, a film sticking auxiliary device (also called a film sticking device) on the market generally only can ensure the accuracy of sticking an electronic product protective film on a mobile phone screen, but in the film sticking process, the electronic product protective film is still parallel to the mobile phone screen in the sticking process, so that the bad condition of the first film sticking mode is caused, bubbles are easily generated, all the bubbles cannot be well eliminated at the later stage, the film sticking quality cannot be ensured, and the use requirement of an operator cannot be well met.

In order to overcome the above problems, the present inventors have proposed a "film pasting device for electronic devices", which adopts a technical solution that a support bar is disposed on a bottom plate of a film pasting device, and after the film pasting device connected with a protective film of an electronic product is covered on an electronic device such as a mobile phone, the support bar will form a barrier for the electronic device due to the presence of the support bar, so as to ensure a gap between the electronic device and an inner surface of the bottom plate. Because the supporting bars on the two opposite sides have height difference, a certain gap still exists between the electronic product protective film on the higher side and the surface of the electronic equipment, the gap can ensure that the electronic product protective film on the higher side cannot be in contact with the surface of the screen of the electronic equipment, one end of the electronic product protective film on the lower side is firstly in contact with one end of the screen of the electronic equipment, and then the automatic laminating and exhausting processes are realized by utilizing the self-weight and self-adhesive characteristics of the electronic product protective film, so that the film pasting is completed at one time.

Among the above-mentioned technical scheme, if realize once only accomplishing the pad pasting, promptly after taking off the pad pasting ware, the automatic laminating of protection film is on electronic equipment's screen, and the protection film also separates by oneself with leaving the type membrane simultaneously, and it is still connected on the pad pasting ware through location gluing from the type membrane when taking off the pad pasting ware. Therefore, it is necessary to ensure that the adhesive force formed by the first adhesive layer 420 is smaller than the adhesive force of the second adhesive layer 410, so that the protective film 41 can be smoothly adhered to the screen of the electronic device through the second adhesive layer 410, and meanwhile, the protective film 41 can overcome the adhesive force of the first adhesive layer 420, and the protective film is smoothly separated from the release film 42. However, in actual practice, there are the following difficulties:

1. since the glue of the adhesive layer is provided by an upstream enterprise, the adhesive force of the adhesive layer is determined, the downstream enterprise is difficult to change the glue formula and adjust again, and the adjustment is difficult.

2. Because in the process of bonding the protective film and the electronic screen, the deformation strength of the protective film increases with the increase of the bonding area, especially, the edge position close to complete attachment depends on the self-adhesive property of the second adhesive layer 410, it is difficult to completely attach the protective film to the screen, and usually, the area close to the edge finally still needs to be manually pressed.

In view of the above problems, the present inventors have made a continuous improvement and have proposed the following technical solutions.

The utility model has the following contents:

The utility model relates to an electronic product protection film external member, it has a protection film that can laminate at electronic product screen surface such as cell-phone, panel computer to protect the screen.

As shown in fig. 2, the electronic product protective film kit includes: the protective film 1 is attached to the upper surface and the lower surface of the protective film 1 respectively through a release film 2 and a protective plate 3. The protective film 1 can adopt a toughened glass protective film or a transparent plastic plate protective film and the like, and the protective film is hard in texture and can be well prevented from being scratched, so that the screen of an electronic product is protected.

The protection film 1 has a smooth surface (upper surface) and a viscose surface (lower surface), and is attached to the smooth surface and the viscose surface of protection film respectively from type membrane 2 and protection shield 3. Specifically, the surface of the release film 2 attached to the protective film 1 is coated with a first adhesive layer 20, and the surface of the protective film 1 attached to the protective plate 3 is coated with a second adhesive layer 10. The release film 2 is attached to the upper surface of the protective film 1 by a first adhesive layer 20 thereof, and the protective plate 3 is attached to the lower surface of the protective film 1 by a second adhesive layer 10 on the protective film 1. The release film 2 is used to protect the upper surface of the protective film 1, so as to ensure that the upper surface of the protective film 1 is smooth and has no scratches before the user uses the protective film. The protective plate 3 protects the second adhesive layer 10 on the lower surface of the protective film 1, and ensures that the second adhesive layer 10 is sticky and does not adhere to impurities, dust, and the like.

In this embodiment, the first adhesive layer 20 is not completely coated on the surface of the release film 2, that is, at least one blank area 200 where the first adhesive layer 20 is not disposed exists on the surface of the release film 2 attached to the protective film 1. These blank regions 200 are located at the edge of one side of the release film 2. Specifically, the blank regions 200 are located in two corner regions of one side edge of the release film 2, as shown in fig. 2. Of course, the blank area 200 can also be located at the area near the edge of one side of the release film 2, as shown in fig. 3. Alternatively, the blank area 200 is formed by combining a plurality of blank cells 201, as shown in fig. 4. These blank regions 200 may be formed directly without applying glue, or may be formed by covering, that is, attaching a thin film to the corresponding region.

Set up the blank region 200 that does not coat first viscose layer 20 on the type membrane 2, the region at these blank regions 200 places will reduce from the adhesive force of type membrane 2 to protection film 1, can be convenient for like this in the later stage pad pasting operation from the mutual separation between type membrane 2 and the protection film 1.

In addition, protection shield 3 adopts transparent plastic board preparation usually, the utility model provides a protection shield 3 not only has the function of protection film 1, and it has locate function in addition. The peripheral edges of the protection plate 3 are respectively formed with positioning flanges 31 protruding outwards, and the positioning flanges 31 protrude out of the edges of the protection film 1. As shown in fig. 2, in the present embodiment, the positioning flange 31 on the protection plate 3 includes: a first positioning flange 311, a second positioning flange 312, a third positioning flange 313 and a fourth positioning flange 314 which are symmetrically arranged at the left and right sides of the protection plate 3. The peripheral contour of these positioning flanges 31 forms an area that corresponds exactly to the contour of the electronic device to which the film is to be applied. Therefore, the whole electronic product protective film kit can be conveniently positioned with the film sticking device during film sticking.

Fig. 5 is an exploded view of the film of the present invention. When the film is pasted, a film pasting device 5 and a mobile phone 6 needing film pasting are prepared. Wherein the applicator 5 generally comprises: a bottom plate 51 and a frame 52 surrounding the bottom plate 51. The shape enclosed by the frame 52 corresponds to the shape of the mobile phone 6 to be filmed. The frame 52 is used for positioning the mobile phone 6, when the film is pasted, the whole film pasting device 5 is covered on the mobile phone 6, and the mobile phone 6 and the film pasting device 5 are positioned because the shape surrounded by the frame 52 corresponds to the shape of the mobile phone 6. The edge of the inner surface of the bottom plate 51 in the film sticking device 5 is provided with a supporting strip 53; among the support bars 53, the support bars 53 positioned at opposite sides of the bottom plate 51 have a height difference. Due to the supporting bars 53, after the film sticking device 5 is covered on the mobile phone 6, the screen of the mobile phone cannot contact the inner surface of the bottom plate 51, and meanwhile, due to the height difference of the supporting bars 53 on the two opposite sides of the bottom plate 51, after the film sticking device 5 is covered on the mobile phone 6, the screen of the mobile phone 6 and the inner surface of the bottom plate 51 are in a relatively inclined state, so that the automatic film sticking is favorably realized subsequently, and bubbles are prevented from appearing after the film sticking.

As shown in FIG. 5, the film pasting process of the present invention is as follows:

the first step is as follows: in order to realize the connection between the film sticking device 5 and the protection film kit, the inner surface of the bottom plate 51 of the film sticking device 5 may be coated with the adhesive 510, the adhesive 510 may be completely coated on the inner surface of the bottom plate 51, or may be partially coated, but it is necessary to generate enough adhesive force to ensure that the protection film kit does not fall off after being placed in the film sticking device 5. Of course, the adhesive 510 can be replaced by other materials such as double-sided tape, adhesive tape, etc.

In the regional in-process of enclosing establishing at frame 52 with electronic product protection film external member, must ensure the two location accurate, the utility model discloses it realizes the location just to utilize the location flange 31 on the protection shield 3. Since the protective plate 3 having the positioning flange 31 has substantially the outer shape of the mobile phone 6 and the shape of the region surrounded by the frame 52 is the same as the outer shape of the mobile phone 6, the entire electronic product cover assembly and the film applicator 5 can be positioned directly when the electronic product cover assembly is placed in the region of the frame 52.

The second step is that: after the electronic product protective film assembly is positioned on the film applicator 5, the user can pinch the extension plate 32 to uncover the protective plate 3, and at this time, the lower surface of the protective film 1 coated with the second adhesive layer 10 is completely exposed.

The third step: the film sticking device 5 for removing the protective plate 3 is buckled on the mobile phone 6, and the screen surface of the mobile phone 6 faces to the surface of the second adhesive layer 10 of the protective film 1. Due to the existence of the supporting strip 53 on the film sticking device 5, the supporting strip 53 will form a barrier to the mobile phone, and ensure that the screen of the mobile phone 6 is not in complete contact with the second adhesive layer 10. Meanwhile, because the height difference exists at the two opposite sides of the supporting bar 53, the screen of the mobile phone 6 and the second adhesive layer 10 are relatively inclined at this time. On one side of the lower support bar 53, the screen of the mobile phone 6 first contacts with the corresponding side edge of the second adhesive layer 10, or is pressed by the pressing plate 50 or the through hole formed on the film sticking device 5, so that the screen of the mobile phone 6 first contacts with the side edge of the second adhesive layer 10. At this time, under the action of the self-weight and self-adhesive characteristics of the protective film 1, the protective film 1 is gradually attached to the other end along the attached end, and in the process of attaching, air is automatically discharged to the region which is not attached until the whole protective film 1 is completely attached to the screen of the mobile phone 6.

The third step described above is a case of an ideal state, and to realize this state, it is necessary to ensure that the automatic adhesion force between the protective film 1 and the mobile phone screen during the attaching process is larger than the adhesion force of the release film 2 to the protective film 1, otherwise it is difficult to realize the complete attaching. In practical tests, as the area where the protective film 1 is attached to the screen is enlarged, the edge where the attachment is completed is reached, that is, the edge is close to the upper side of the support pins 53. At this moment, due to the isolation of the higher side supporting bar 53, the gap between the protective film 1 and the screen is larger, the self deformation capacity of the protective film 1 is reduced, and the self-adhesion acting force between the protective film 1 and the screen cannot directly pull the protective film 1 off from the release film 2, so that an area which is not completely attached exists. It is common practice to remove the applicator 5 and then apply the incompletely applied regions by manual pressure. And the utility model discloses a mode do: at least one blank area 200 without the first adhesive layer 20 is formed on the surface of the release film 2 attached to the protective film 1. These blank areas 200 are located at the edge of one side of the release film 2 (i.e. the edge near the upper side supporting strip 53). The release film 2 has a blank area, so that the adhesive force between the release film 2 and the protective film 1 is low in the area range, the self-adhesive force between the protective film 1 and the screen can easily overcome the adhesive force between the release film 2 and the protective film 1, and the protective film 1 is pulled off from the release film 2, so that the whole attaching operation can be completed smoothly. Meanwhile, the release film 2 can be separated from the protective film 1.

The fourth step: the applicator 5 is removed from the mobile phone 6, and the release film 2 is adsorbed on the applicator 5 by the adhesive 510 while the protection film 1 is attached on the screen of the mobile phone 6 while the applicator 5 is removed. Thus, the whole film pasting operation is completed.

The utility model discloses can used repeatedly, during the used repeatedly, only need take off remaining from type membrane 2 in the pad pasting ware 5, change one set of new electronic product protection film external member, repeat above-mentioned step can.

Of course, the above description is only an exemplary embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent changes and modifications made by the constructions, features, and principles of the present invention in accordance with the claims of the present invention are intended to be included in the scope of the present invention.
