Technical Field

[0001] The utility model relates to the technical field of film sticking equipment, in particular to a film sticking device. Background Art

[0002] With the advent of the Internet age, electronic devices are becoming more and more indispensable tools in our lives. However, the screens of electronic devices are sometimes too fragile and are often accidentally scratched or even broken, which affects the display effect and aesthetics of the electronic devices. Replacing the screen requires a lot of money and time. Therefore, people usually stick a layer of positioning film on the screen of the electronic device to protect the tablet or mobile phone screen.

[0003] In real life, when applying a film to a mobile phone or mobile terminal screen, a film applying tool is usually used to assist in applying the film. Originally, a dust-free bin and a screen film kit were used to apply the film together. However, in actual use, when the dust-free bin is turned upside down to cover the mobile terminal, there is a problem that the dust-free bin is accidentally dropped, and the placed screen film kit falls out of the dust-free bin;

[0004] To solve this problem, manufacturers will stick a double-sided tape between the dust-free bin and the positioning film, and also stick a double-sided tape between the release film and the positioning film. The adhesion of the double-sided tape can be used to prevent the screen film kit from loosening from the dust-free bin when the dust-free bin falls to the ground.

[0005] However, during actual use, our company discovered that there is still room for optimization of the structure and components of this existing product in order to reduce production costs.

[0006] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute the prior art that is already known to one of ordinary skill in the art. Utility Model Content

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a film applicator, comprising a dust-free bin shell for connecting a screen film and a mobile terminal, the screen film comprising a positioning film, a protective film, a release film and a pull strip which are sequentially placed in a laminated manner, a double-sided adhesive is adhered to one side between the positioning film and the release film, the positioning film has a through hole on the side close to the double-sided adhesive, so that the double-sided adhesive between the positioning film and the release film is located directly above the through hole, and in a working state: the release film and the double-sided adhesive are deformed downward under pressure and pass through the through hole, and the bottom surface of the double-sided adhesive is bonded to the surface of the dust-free bin shell.

[0009] Preferably, the double-sided adhesive is configured as a double-sided adhesive tape;

[0010] Double-sided tape is used to achieve the purpose of having adhesion on both sides of a double-sided adhesive.

[0011] Preferably, the double-sided adhesive member is configured as a rectangle as a whole, and the through hole is configured as a rectangle matching the shape of the double-sided adhesive member;

[0012] After the rectangular convenient double-sided adhesive passes through the through hole and contacts the surface of the dust-free chamber shell, a straight line is formed for bonding, thereby improving the adhesion of the bonding.

[0013] Preferably, the overall size of the double-sided adhesive is 1.1-1.5 times the overall size of the through hole, so that the outer circle of the double-sided adhesive is bonded to the top surface of the positioning film, and the middle part does not contact the positioning film.

[0014] Preferably, an anti-foolproof groove is formed at one end of the positioning film, and an anti-foolproof protrusion matching the shape of the anti-foolproof groove is fixedly connected to the top surface of the dust-free bin shell;

[0015] The cooperation between the fool-proof protrusion and the fool-proof groove can enable the positioning film, the protective film, the release film and the pull strip to be centered on the side close to the fool-proof protrusion.

[0016] Preferably, the dust-free bin shell includes a bottom plate, two symmetrically distributed limiting ribs fixedly connected to the top surface of the bottom plate, and a pull-out groove opened at one end of the limiting rib away from the anti-foolproof protrusion, and the pull strip passes through the pull-out groove and is slidably connected to the pull-out groove.

[0017] Preferably, a double-sided adhesive sheet is fixedly mounted on the top surface of the bottom plate away from the double-sided adhesive attachment;

[0018] The double-sided adhesive sheet is used together with the double-sided adhesive to prevent the dust-free bin shell from accidentally falling off, causing the positioning film, protective film, release film and pull strip to detach from the dust-free bin shell.

[0019] Preferably, both sides of the positioning film away from one end of the double-sided adhesive attachment are fixedly connected with middle ears, and the middle ears are in close contact with the side walls of the limiting rib plate;

[0020] It plays a centering role on the middle ear, away from the positioning membrane and away from the side of the anti-foolproof protrusion.

[0021] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0022] 1. This product discards the double-sided adhesive originally located between the dust-free bin shell and the positioning film, opens a through hole on the positioning film, and allows the double-sided adhesive originally located between the positioning film and the release film to pass through and adhere to the surface of the dust-free bin shell. This not only achieves the effect of the original product, but also reduces the use of a double-sided adhesive, reducing production costs;

[0023] 2. This product further improves the alignment of the positioning film, protective film, release film and pull strip in the dust-free chamber shell by fixing the centering ears on both sides of the end of the positioning film away from the anti-fool protrusion, and cooperates with the anti-fool protrusion and the anti-pass groove, thereby improving the quality of film application;

[0024] 3. By designing the size between the through hole and the double-sided adhesive, the outer ring of the double-sided adhesive can adhere to the positioning film and the release film as in the prior art, and the middle part can be recessed downward to contact the surface of the dust-free chamber shell.
