[0001] The present application relates to the technical field of film pasting tools, and in particular to a glue-coating film pasting device 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 protective film, such as a 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] Some existing protective films do not have a built-in glue layer, so you need to consider using transparent sticky glue to stick the protective film. To ensure that the glue is sticky enough, high-viscosity screen glue specifically for the screen is usually used, and the screen glue needs to be dripped on different positions on the screen before applying the film. However, existing users drip glue manually during the glue dripping process, which leads to problems such as poor control of the glue dripping position and poor glue dripping uniformity.

DETAILED DESCRIPTION

[0040] 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.

[0041] like Figure 1 , Figure 2 As shown, this embodiment proposes a glue-coating film applicator for applying a film to the screen of a mobile terminal. The mobile terminal in this embodiment is a mobile phone 500, and can also be an electronic device such as a tablet computer, an e-book, a smart watch, etc. To facilitate the structural description of this embodiment, taking the mobile phone 500 as an example, the long side direction of the mobile phone 500 is the length direction, the short side direction is the width direction, and the thickness direction is the up and down direction. When the glue-coating film applicator is used, the screen of the mobile phone 500 is in the up direction. Figure 2 As shown, the glue-applying film applicator of this embodiment mainly includes: a housing 100, a glue-applying bracket 200 and a glue cylinder 300. The housing 100 is provided with a receiving cavity 110, and the receiving cavity 110 has a lower opening, such as Figure 1 , Figure 2 As shown, when the mobile phone 500 is placed with the screen facing upward, the housing 100 can be covered on the mobile phone 500 through the accommodating cavity 110, so that the accommodating cavity 110 can accommodate the mobile phone 500. A limiting cavity 120 is opened on one side of the accommodating cavity 110. The limiting cavity 120 is located on the upper side of the accommodating cavity 110. The limiting cavity 120 has an upper opening, so that the screen of the mobile phone 500 is exposed in the limiting cavity 120. Figure 4As shown, the limiting cavity 120 is used to accommodate and limit the protective film 400. The protective film 400 can be limited from above by the limiting cavity 120, so as to be aligned with the screen of the mobile phone 500 in the accommodating cavity 110. The gluing bracket 200 is movably arranged on the shell 100 along the length direction. The gluing bracket 200 can be located above the shell 100 and move across the upper opening of the limiting cavity 120 in the length direction. The glue cylinder 300 is arranged on the glue bracket 200 and is located on the side of the accommodating cavity 110 away from the accommodating cavity 110. The glue cylinder 300 is connected to the glue bracket 200, and the glue bracket 200 cooperates with the shell 100 to locate the glue dripping position. As shown Figure 2 As shown, after the glue cylinder 300 is installed on the glue-applying bracket 200, the glue-dropping port of the glue cylinder 300 faces downward. Since the glue-applying bracket 200 is positioned at the glue-dropping position in the length direction of the shell, the glue cylinder 300 drips glue onto the mobile phone screen at this position, and the glue is located in the middle position in the width direction of the mobile phone screen, or in the center position of the surface of the mobile phone screen. Figure 6 As shown, after the glue is dripped, you can remove the glue cylinder 300 or take the empty glue cylinder and manually drag the glue-applying bracket 200 to move to the predetermined position on the rear side of the shell 100 in the length direction, so that the front end of the limiting cavity 120 is released, and the protective film 400 is placed in the limiting cavity 120, so that the front end of the protective film 400 first contacts and adheres to the screen, and the rear end is supported by the glue-applying bracket 200 so that the rear end of the protective film 400 is lifted up to assist in pasting the protective film 400. When the front end of the protective film 400 is bonded, completely remove the glue-applying bracket 200 so that the rear end of the film is also bonded to the screen. Figure 7 As shown, the protective film is irradiated above the housing by a curing lamp 600 to cure the glue on the protective film bonded to the screen, making the bonding more stable, thereby completing the entire film-sticking process.

[0042] like Figure 1 , Figure 2 As shown, the glue-applying film applicator in this embodiment accommodates the mobile phone 500 through the accommodating cavity 110 provided on the housing 100, so that the screen of the mobile phone 500 is exposed in the limiting cavity 120, and the glue cylinder 300 is provided on the glue-applying bracket 200 and is located above the limiting cavity 120. The glue-applying bracket 200 is limited at the gluing position of the housing, so that the glue cylinder 300 is fixed above the mobile phone screen for glue dripping, thereby gluing the screen of the mobile phone 500 in the accommodating cavity 110, and the glue-applying point can be guaranteed to be in the middle position of the left and right directions of the screen. Positioning through the glue-applying bracket facilitates the user to control the glue dripping position, so that the glue can be applied to the center position of the left and right sides of the screen, ensuring the uniformity of the glue coating.

[0043] like Figure 1 , Figure 2 , Figure 3As shown, further, the glue coating bracket 200 in this embodiment specifically includes: a support portion 210 and a connecting portion 220. A mounting position 230 is provided on the support portion 210, and the rubber cylinder 300 is detachably connected to the support portion 210 through the mounting position 230. The connecting portion 220 is arranged on the support portion 210, and the support portion 210 is slidably arranged on the housing 100 along the length direction through the connecting portion 220. The support portion 210 is connected to the housing 100 through the connecting portion 220, and the support portion 210 is supported so that the support portion 210 is located on the upper side of the housing 100. When the rubber cylinder 300 is connected to the mounting position 230, the support portion 210 supports the rubber cylinder 300 so that the rubber cylinder 300 is stably fixed above the screen of the mobile phone 500.

[0044] Furthermore, the mounting position 230 in this embodiment includes a mounting hole, which is arranged in the middle of the width direction of the support portion 210. In the specific structure, the mounting hole can be a tapered hole with a larger top and a smaller bottom, and the lower end of the rubber cartridge 300 also adopts a tapered head 310, and the rubber cartridge 300 is inserted into the tapered hole through the tapered head, and the tapered head 310 can expose the tapered mounting hole downward, so that the rubber cartridge 300 can be quickly installed by plugging. In addition, the rubber cartridge 300 can also adopt a threaded head, and the mounting hole correspondingly adopts a threaded hole, so that the connection between the rubber cartridge 300 and the mounting position 230 is achieved by threaded connection.

[0045] The mounting hole is set at the center of the width direction of the support part 210. The glue point on the screen is at the midpoint of the width direction of the screen. After the protective film 400 is applied, the glue point in the center is dispersed from the midpoint to the surroundings, so that the glue on the screen in the width direction is more evenly dispersed.

[0046] It is easy to imagine that the mounting position 230 can also adopt an open buckle structure, a clamp locking structure, etc. on the outer edge of the support part 210 to fix the rubber cylinder 300.

[0047] like Figure 2 , Figure 3 , Figure 4 As shown, further, the housing 100 in this embodiment includes a bearing surface 130, which is located on both sides of the width direction of the limiting cavity 120, and the bearing surface 130 is arranged upward. Two connecting parts 220 are provided, and the two connecting parts 220 are respectively arranged on both sides of the width direction of the supporting part 210, and connected to the housing 100. The supporting part 210 is supported by the connecting parts 220 on both sides, so that the glue-spreading bracket 200 is more stably connected to the housing 100, and the supporting part 210 has a strong bearing capacity. The user can directly drag the supporting part 210 to drive the entire glue-spreading bracket 200 to move. In the case of relatively large force, the glue-spreading bracket 200 is not easy to deform, and a more stable support is achieved for the rubber cylinder 300.

[0048] like Figure 1 , Figure 3 , Figure 5 As shown, in the specific structure, the connecting part 220 includes: a transverse side plate 221 and a longitudinal side plate 222. The transverse side plate 221 abuts against the bearing surface 130, and the longitudinal side plate 222 is connected to the transverse side plate 221 in the up-down direction and is located on the outer side of the lower side wall 131 of the shell 100. The lower side wall 131 of the shell 100 is the side wall of the part below the bearing surface 130 of the shell 100. The transverse side plate 221 is supported by the bearing surface 130, so that the connecting part 220 can slide smoothly on the transverse side plate 221 along the length direction, and a space for accommodating the entire shell 100 is formed between the longitudinal side plates 222 on both sides in the width direction, ensuring that the glue-coating bracket 200 will not separate from the shell 100 in the width direction.

[0049] It is easy to imagine that only one connecting portion 220 may be provided, connected to the housing 100 on one side in the width direction, and the rubber cylinder 300 is suspended above the screen of the mobile phone 500 through the supporting portion 210 .

[0050] like Figure 1 , Figure 3 , Figure 5 As shown, further, a guide ridge 132 is provided on the lower side wall 131 of the shell 100 in this embodiment toward the outside in the width direction, the upper surface of the guide ridge 132 is flush with the bearing surface 130, and the guide ridge 132 protrudes toward the outside in the width direction to form a guide rail structure. A hook 223 is provided on the inner wall of the longitudinal side plate 222, and a guide groove 224 is formed between the hook 223 and the transverse side plate 221, and the guide groove 224 is sleeved on the guide ridge 132. Through the guiding effect of the guide ridge 132 on the guide groove 224, the sliding process of the glue-coating bracket 200 is made more stable, and in the process of sliding along the length direction, it is ensured that no large shaking occurs during the movement process, and the glue-coating bracket 200 is ensured to slide more smoothly on the shell 100.

[0051] Furthermore, the housing 100 in this embodiment further includes: side baffles 140, which are arranged in the up-down direction and located on both sides of the width direction of the limiting cavity 120. The side baffles 140 are vertically located on the bearing surface 130, and the inner side surfaces of the side baffles 140 serve as the inner walls in the width direction of the limiting cavity 120 to limit the protective film 400.

[0052] The support part 210 in this embodiment specifically includes: a support transverse plate 211 and a longitudinal inner plate 212. The support transverse plate 211 is located above the limiting cavity 120, and the edge of the support transverse plate 211 along the length direction can be set as a handle position, such as a corrugated edge, so that the user can drag the glue-coating bracket 200 by hand. The longitudinal inner plate 212 is arranged on both sides of the width direction of the support transverse plate 211, and is respectively connected to the transverse side plates 221, and the longitudinal inner plates 212 on both sides are respectively against the side guard plates 140. Guidance can also be achieved by cooperating with the side guard plates 140 on both sides and the longitudinal inner plate 212, and the distance between the side guard plates 140 in the up-down direction is larger, so that the contact area with the longitudinal inner plate 212 is also larger, so that the movement process of the glue-coating bracket 200 is more stable during the guided movement process.

[0053] like Figure 1 , Figure 2 As shown, further, a limiting boss 141 is provided on the side baffle plate 140 in this embodiment, and the limiting boss 141 is used to abut against the longitudinal inner plate 212 to limit the movement of the glue-coating bracket 200 toward the front end of the housing 100, as shown in FIG. Figure 2 As shown, the limiting boss 141 cooperates with the glue-applying bracket 200 to locate the gluing position. When the glue-applying bracket 200 moves forward to abut against the limiting boss 141, the glue-applying bracket 200 is limited to this position. At this time, the lower position of the glue cylinder 300 on the glue-applying bracket 200 is the gluing position to ensure that the gluing position is in the middle of the width direction of the screen. In addition, the gluing position can also be at the front end position in the length direction of the screen, that is, less than half of the length of the screen, for example, at one-third of the length direction of the screen. In this way, the front end of the screen is glued first, the front end of the protective film is first bonded to the screen, and then the rear end is bonded, which can effectively reduce the generation of bubbles during the film application process. After the gluing is completed, the glue-applying bracket 200 moves backward from the position of the limiting boss 141, and reaches the predetermined position at the rear end of the shell 100 for auxiliary film application.

[0054] like Figure 1 , Figure 3 , Figure 6As shown, further, the glue-coating bracket 200 in this embodiment is also provided with a film-supporting portion 240, which is provided on the glue-coating bracket 200 and is located on the opposite side of the removal direction of the glue-coating bracket 200. The film-supporting portion 240 is specifically provided at the front end of the supporting portion 210, and after the glue coating is completed, when the glue-coating bracket 200 is pulled to the rear end of the housing 100. The film-supporting portion 240 is still located in the limiting cavity 120. At this time, a protective film 400 is placed in the limiting cavity 120. The front end of the protective film 400 is in contact with the screen of the mobile phone 500, while the rear end is covered on the film-supporting portion 240 and is supported. In this way, the position of the front end of the protective film 400 can be adjusted first, and the rear end can be fine-tuned because it does not contact the screen, so that the protective film 400 is initially aligned with the screen, and the protective film 400 is squeezed from the front end, and then the glue-coating bracket 200 at the rear end is slowly pulled out, so that the rear end of the protective film 400 is gradually separated from the film-supporting portion 240. When the glue-coating bracket 200 drives the film-supporting portion 240 to completely escape from the limiting cavity 120, the rear end of the protective film 400 is also in contact with the screen. In this way, not only a more accurate film-sticking process is achieved, but also the film-sticking process in which the front end is first bonded and then the rear end is bonded greatly reduces bubbles in the film-sticking process, so that there are basically no bubbles between the entire protective film and the screen, making the film-sticking process smoother.

[0055] like Figure 1 , Figure 3 As shown, the film support part 240 includes a support plate 241 extending a predetermined length in the length direction, and the support plate 241 is fixed at the middle position in the width direction of the support horizontal plate 211 and faces forward. A reinforcing rib plate 242 is arranged between the support plate 241 and the support horizontal plate 211, and the reinforcing rib plate 242 not only plays a reinforcing role, but also can support the rear end of the protective film 400 to a greater extent, so as to facilitate film application.

[0056] like Figure 1 , Figure 6As shown, in another solution, in order to make the glue-applying bracket move to the rear end position of the shell more accurately, a blocking platform 142 is provided on the side baffle plate 140 of the shell. The blocking platform 142 has a small protruding distance and abuts against the longitudinal inner plate 212 to block the movement of the glue-applying bracket 200 toward the rear end of the shell 100. The blocking platform 142 cooperates with the glue-applying bracket 200 to locate the rearward position of the glue-applying bracket 200, thereby making the position of the film support part 240 in the shell 200 more accurate. When the protective film 400 is placed in the limiting cavity 120, the front end of the protective film 400 is in contact with the screen of the mobile phone 500 and the rear end of the protective film 400 can just cover the film support part 240 and be supported, thereby making the film application process more convenient. When the longitudinal inner plate 212 continues to be pulled backward, a large pulling force needs to be applied. Since the longitudinal inner plate 212 is squeezed and deformed by the blocking platform 142 on both sides in the width direction, the longitudinal inner plates 212 on both sides are opened, so that the longitudinal inner plates 212 on both sides slide over the blocking platform 142. The glue-coating bracket 200 is pulled out from the rear end of the shell, and the rear end of the protective film 400 is gradually separated from the film-supporting part 240. When the glue-coating bracket 200 drives the film-supporting part 240 to completely escape from the limiting cavity 120, the rear end of the protective film 400 falls and adheres to the screen.

[0057] like Figure 1 , Figure 3 As shown, further, a glue absorbing part 150 is provided on the inner wall of the limiting cavity 120 in this embodiment. The glue absorbing part 150 can be a glue absorbing sponge, a foam block, etc. A plurality of glue absorbing grooves are provided at intervals on the inner wall at the front end of the limiting cavity 120 or / and the inner walls on the left and right sides, and the glue absorbing part 150 is installed in the glue absorbing groove so that the inner surface of the glue absorbing part 150 is flush with the notch plane of the glue absorbing groove, so that the inner surface of the glue absorbing part 150 can also limit the protective film 400 in the limiting cavity 120. When excess glue overflows from the edge of the screen, it is absorbed by the glue absorbing part 150 on the inner wall, thereby preventing the residual glue from adhering to the surface of the mobile phone 500 housing or the protective film 400.

[0058] like Figure 3 As shown, further, four adjusting screws 160 are provided at the edge of the housing 100 in this embodiment, and the adjusting screws 160 are screwed on the housing 100. When the housing 100 is placed on a desktop for film application, the housing 100 may be unstable due to the deformation of the production size or the uneven desktop. In this way, the housing 100 can be leveled by turning the adjusting screws 160 on the four corners. The alignment of the protective film 400 is more accurate.

[0059] Embodiment 2

[0060] like Figure 1 , Figure 6As shown, this embodiment provides a film sticking kit, which includes the above-mentioned glue sticking device and a protective film 400. The glue sticking device is used to apply glue to the device to be stuck, and the protective film 400 is attached to the glued device to be stuck by the glue sticking device.

[0061] like Figure 7 As shown, the film sticking kit further includes a curing lamp 600. The curing lamp 600 is arranged above the housing 100 for irradiation to solidify the glue on the protective film 400 bonded to the screen, making the bonding more stable and completing the entire film sticking process.

[0062] In summary, the glue-applying film applicator and film applicator kit of the present application accommodate the device to be film-applied through the accommodating cavity 110 provided on the housing 100, so that the screen of the device to be film-applied is exposed in the limiting cavity 120, and the glue cylinder 300 is provided on the glue-applying bracket 200 and is located above the limiting cavity 120. The glue cylinder 300 is limited by the cooperation between the glue-applying bracket 200 and the housing 100, so that the screen of the device to be film-applied in the accommodating cavity 110 is glued, and the glue-applying position is in the middle of the width direction. The glue-applying point is made to have the same distance from both sides of the screen in the width direction, so as to ensure the accuracy of the glue-applying position, and the glue-applying process becomes simpler, and the film-applying process of the user is more convenient. After the glue is applied, the glue-applying bracket 200 is moved to the rear end of the housing 100 for positioning, and the protective film 400 is placed in the limiting cavity 120, so that one end of the protective film 400 is first in contact with and bonded to the screen, and the other end is supported by the glue-applying bracket 200 so that the other end of the protective film 400 is lifted up to assist in applying the protective film 400. When one end of the protective film 400 is bonded, the glue-applying bracket 200 is completely removed so that the other end of the film is also bonded to the screen. The step-by-step film-applying method makes it difficult to generate bubbles during the film-applying process, making the film-applying process smoother.
