Description

TECHNICAL FIELD

[0001] The utility model relates to electronic equipment film sticking technical field, especially film assembly and film sticking device. BACKGROUND

[0002] The tempered film has the self-adhesive characteristic, and the self-adhesive characteristic is mainly embodied in that when a part of the tempered film is attached to the electronic equipment screen, even if no external force is applied, the tempered film will continuously expand outward by relying on the stress and gravity of its own material, until the tempered film is fully attached to the electronic equipment screen.

[0003] When the tempered film is used for film sticking, usually one end of the tempered film is aligned with one end edge of the electronic equipment screen, then the tempered film at the end is attached and adhered to the end of the electronic equipment screen, and then the tempered film is released, under the action of the self-weight and self-adhesive characteristic of the tempered film, the tempered film gradually adheres to the other end along the already attached end, in the adhering process, air is automatically discharged to the area that has not been attached, until the whole tempered film is fully attached to the electronic equipment screen. This film sticking method is difficult to complete by manual naked eye, so auxiliary film sticking tools are usually used, for example, the patent CN205554723U discloses a screen film sticking device, the patent CN218463959U discloses a film sticking device with an exhaust chute and capable of removing dust, and the patent CN219029898U discloses a film sticking device with a tempered film and an exhaust chute and capable of removing dust. In particular, the schemes disclosed in the patent CN205554723U and the patent CN219029898U also disclose a dust removal film attached to the tempered film, which realizes the function of completing the dust removal of the mobile phone screen while the film sticking is performed. After the dust removal film is pulled out, the tempered film will gradually adhere to the mobile phone screen by relying on the electrostatic and self-adhesive characteristics of the tempered film, however, in the self-adhesive adhering process, the air bubbles between the tempered film and the mobile phone screen are gathered from both ends of the mobile phone screen to the middle and discharged from the edge, resulting in that part of the air bubbles remain, which leads to poor film sticking effect. Based on this, in order to reduce the generation of air bubbles in the film sticking process, the present application provides an improved film assembly. UTILITY MODEL CONTENTS

[0032] Please refer to Figures 1 to 6 The utility model provides a kind of film pasting device 10, including main body 100 and film component 200.Main body 100 can be made of plastic, metal, ceramic and the like material.Forwards set outer surface 110 and inner surface 120 of main body 100, the direction of relative arrangement can be understood as the thickness direction of main body 100.Main body 100 is provided with accommodating space 101 on the side where inner surface 120 is located, in the embodiment, inner surface 120 is provided with frame 130 connected with main body 100, and frame 130 is enclosed to form accommodating space 101 after being connected with main body 100.It can be understood that accommodating space 101 can also be formed by other ways, for example, recessed groove can be set on inner surface 110 to form accommodating space 101.

[0033] Accommodating space 101 is used to accommodate electronic equipment, to facilitate the screen film pasting of electronic equipment.It should be noted that electronic equipment can be smart phone, tablet computer and the like smart terminal with screen.

[0034] The film assembly 200 is installed in the accommodation space 101, and the film assembly 200 comprises a dust removal film 210, a tempered film 220 and a release film 230 which are laminated in layers, and when the film assembly 200 is installed in the accommodation space 101, the release film 230 should be installed in a posture of facing the accommodation space 101, and after installation, the dust removal film 210 faces the outside, so that the dust removal film 210 abuts against the screen of the electronic device when the film is attached. The dust removal film 210 comprises a stripping layer 211 and a traction layer 212 which are overlapped with each other, the stripping layer 211 is attached to the side of the tempered film 220 which is away from the release film 230, the traction layer 212 is arranged on the side of the stripping layer 211 which is away from the tempered film 220, and the traction layer 212 and one end of the stripping layer 211 form a crease 213. One end of the release film 230 is provided with a fixing portion 231, the fixing portion 231 protrudes from the edge of the tempered film 220 near the position where the crease 213 is located, the fixing portion 231 is provided with an elastic pressing piece 232 on the side which faces the tempered film 220, the elastic pressing piece 232 has a fixed end 233 and a free end 234, the fixed end 233 is connected to the fixing portion 231, and the free end 234 abuts against the side of the traction layer 212 which is away from the stripping layer 211, and the elastic pressing piece 232 is hung on the part of the dust removal film 210 which is located at the position of the crease 213. When the film assembly 200 is used for attaching the film to the electronic device, the screen of the electronic device abuts against the traction layer 212, the traction layer 212 is pulled to make the stripping layer 211 evert from the crease 213, the side of the stripping layer 211 which faces the tempered film 220 moves from one end to the other end of the screen of the electronic device, until the stripping layer 211 is separated from the tempered film 220, and at this time, the free end 234 is hung on the side edge of the tempered film 220 which is away from the release film 230.

[0035] Before the film assembly 200 is used without attaching the film, the free end 234 of the elastic pressing piece 232 abuts against the side of the traction layer 212 which is away from the stripping layer 211, and the elastic pressing piece 232 is hung on the part of the dust removal film 210 which is located at the position of the crease 213, so that the stripping layer 211 cannot easily separate from the tempered film 220, the AB glue of the tempered film 220 cannot easily crack, and the film attaching effect of the tempered film 220 is improved. In addition, when the film assembly 200 is used for attaching the film to the electronic device, especially after the stripping layer 211 is separated from the tempered film 220, the free end 234 is hung on the side edge of the tempered film 220 which is away from the release film 230, the upper position of the tempered film 220 is improved, the AB glue of the tempered film 220 can be sequentially exhausted from bottom to top, and the problem that the AB glue of the tempered film 220 simultaneously adsorbs the screen of the electronic device from both ends to the middle to cause air bubbles due to air trapping is solved. That is, the scheme of the utility model can reduce or even eliminate the generation of air bubbles when the film is attached.

[0036] In an embodiment, the fixing part 231 is integrally formed with the release film 230, the fixing part 231 is provided with a linear groove 235 extending through the fixing part 231 along the thickness direction of the fixing part 231, and the fixing part 231 located in the area surrounded by the linear groove 235 forms the elastic pressing piece 232. In this way, in order to obtain the elastic pressing piece 232, only the linear groove needs to be opened on the integrally formed fixing part 231 and release film 230, without the need to form the elastic pressing piece 232 component, and the subsequent installation process is also saved, thereby greatly reducing the production manufacturing cost. For example Figure 4 The linear groove 235 is shown to include a first groove 2351, a second groove 2352 and a third groove 2353 connected in sequence, the length extension direction of the second groove 2352 is parallel to the width direction of the tempered film 220, the first groove 2351 and the third groove 2353 are symmetrically arranged at both ends of the second groove 2352 and extend away from the tempered film 220, and the first groove 2351 and the third groove 2353 are arranged at an angle with the second groove 2352, respectively. Of course, in other embodiments, the linear groove 235 can also have other forms, for example, the linear groove 235 can also be a straight linear groove, for example, the linear groove 235 can only include the second groove 2352, and the part of the straight linear groove can also be understood as the aforementioned elastic pressing piece 232. When hanging, the crease 213 directly extends into the straight linear groove.

[0037] It should be noted that the elastic pressing piece 232 can be formed by opening a linear groove, or a spring piece can be arranged on the fixing part 231 to form the aforementioned elastic pressing piece 232. At this time, the fixing part 231 should have good hardness and rigidity, so the fixing part 231 can be made of a plate material spliced with the release film 230.

[0038] In an embodiment, the edge of the tempered film 220 is provided with a black frame area, and after the release layer 211 is separated from the tempered film 220, the free end 234 is hung on the black frame area. On the one hand, the tempered film 220 with the black frame area can effectively improve the strength of the tempered film, and on the other hand, since the free end 234 is not hung on the inner area of the tempered film 220, but is hung on the black frame area, the screen will not be damaged when the film is pasted. Further, the black frame area extends a mesh plate away from the middle area of the tempered film 220, and the free end is hung on the area where the mesh plate is located. The mesh plate is used to cover the array of earpiece holes on the front side of the screen for electronic devices with the screen side having an earpiece.

[0039] In an embodiment, one end of the dust removal film 210 is provided with two lugs 214 with a width smaller than the peeling layer 211 and the traction layer 212, the lugs 214 extend out of the edge of the tempered film 220, the opposite ends of the two lugs 214 are connected with the peeling layer 211 and the traction layer 212 respectively, and the other ends of the two lugs 214 close to each other are connected with each other and form a crease 213 at the connection position. The provision of the two lugs 214 can increase the hanging area of the elastic pressing sheet 232. If the two lugs 214 are not provided, in order to avoid the elastic pressing sheet 232 extending into the internal area of the tempered film 220, the elastic pressing sheet 232 can be designed to be very short, only matching the width of the black frame area, and it is impossible to hang the dust removal film 210, or it is easy to fall off.

[0040] In an embodiment, one of the lugs 214 is integrally formed with the peeling layer 211, and the other lug 214 is bonded with the traction layer 212. The above design is only to facilitate the splicing of the peeling layer 211 and the traction layer 212. In other embodiments, the peeling layer 211 and the traction layer 212 can also be designed as an integrally formed structure, and at this time, only the crease 213 needs to be formed at the middle position of the dust removal film 210.

[0041] In an embodiment, the fixed part 231 is provided with two positioning holes 236 penetrating through the fixed part 231 along the thickness direction of the fixed part 231, the two positioning holes 236 are arranged along the width direction of the tempered film 220, and the two positioning holes 236 are located on both sides of the elastic pressing sheet 232. The two positioning holes 236 are used to match the two positioning protrusions 140 provided on the main body 100, so as to facilitate the fixing of the release film 230 during the film pasting process. It should be understood that in other embodiments, other ways can also be used to fix the release film 230, for example, the way of fixing the release film by bonding the adhesive through the window can be referred to the patent CN218463959U. Further, at least one of the shape and size of the two positioning holes 236 can be designed to be different. In this way, the user will not put it upside down when installing the film assembly 200 into the accommodation space 101 during the film pasting process.

[0042] Although the present application has been described with reference to several exemplary embodiments, it is understood that the terms used are illustrative and not restrictive, and the present application is not limited to any of the above details. Since the present application can be embodied in various forms without departing from the spirit or essential characteristics thereof, it should be understood that the above-described embodiments are not limited to any of the above-described details, but are to be interpreted broadly and liberally in the spirit and scope of the appended claims, and all modifications and changes coming within the scope of the claims or their equivalents are intended to be embraced by the claims.
