Background
In the manufacturing process of terminal equipment (such as mobile phones and tablet computers), the screen is usually mounted on the main body of the terminal equipment, and a gap between the edge of the screen and the main body must be filled with a gap filling glue. The joint filling glue can prevent water or dust in the external environment from entering the terminal equipment from the gap when closely bonding the screen on the main body, so as to achieve the purposes of water resistance and dust resistance.
When assembling the screen of the terminal device, a ring of caulking glue is usually dispensed along the edge of the main body by a dispenser, and then the screen is embedded in the main body. During the process of embedding the screen into the main body, the caulking glue may overflow from the gap between the screen and the main body due to the extrusion of the screen. Therefore, after the screen is installed, the overflowing caulking compound needs to be wiped off by a glue wiper.
In recent years, in order to make a terminal device more portable and easy to use and to improve the feel and the appreciation, the terminal device has become more and more lightweight. And thinner terminal equipment means narrower side walls of the terminal equipment body. Because the side key is arranged on the side wall of the main body, the distance between the side key and the overflowing joint sealing glue is closer and closer; when the gap filling glue is erased, the overflowing gap filling glue can enter the side key more easily, and the risk of failure of the side key is increased.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that, if not conflicted, the various features of the embodiments of the invention may be combined with each other within the scope of protection of the invention. Additionally, while functional block divisions are performed in the device diagrams, with logical sequences shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than the block divisions in the device diagrams, or the flowcharts.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1a and 1b, fig. 1a and 1b are respectively schematic structural diagrams of a terminal device before and after screen installation according to an embodiment of the present invention, as shown in fig. 1a and 1b, a terminal device 100 includes a main body 10 and a screen 20, where the main body 10 includes a side wall 11, a bottom wall, and a side key 12; the side wall 11 is provided with a mounting hole 13, and the side key 12 is arranged in the mounting hole 13. In general, the side key 12 includes a power key 121 and a volume key 122, and the mounting holes 13 include a mounting hole 131 for receiving the power key 121 and the mounting hole 131 and a mounting hole 131 for receiving the volume key. When the screen 20 is mounted on the main body 10, a caulking paste is generally applied to an edge of a side surface of the main body 10 away from the bottom wall, and then the screen 20 is attached to the main body 10. During the process of attaching the screen 20 to the main body 10, the caulking compound may overflow from the slit 30 after being pressed by the screen 20. Since the gap 30 is close to the side key 12, the gap between the side key 12 and the mounting hole 13 is easy to enter the side key 12 during the glue wiping process.
Various methods can be used for solving the problem of side key glue feeding of the terminal equipment, for example, when a glue wiping machine is used for wiping glue, the probability of side key glue feeding can be reduced by adjusting the angle of the glue wiping machine; however, this method has a high risk of side-bonding into the glue. For example, before the screen is installed, ultraviolet curing glue (UV glue) can be filled in the gap around the side key in advance and cured, after the screen is installed, and the gap filling glue is erased, the cured UV glue is peeled off; however, the method requires filling and then peeling off the UV glue, and the process is relatively complicated; and the UV adhesive has higher cost and can also cause the problem that the paint of the middle frame falls. In addition, the side keys are not installed, the installation holes are sealed through the protective films, after the screen is installed, the gap filling glue is erased, the protective films are removed, and the side keys are assembled; however, this method is relatively difficult in assembly of the side key, and the sealability around the side key is relatively poor.
The key point of the invention is that after the side key is installed, the protective film is firstly adhered to the side key and the side wall around the side key, the protective film is utilized to shield the gap around the side key, then the gap between the edge of the screen and the middle frame is filled with the gap filling glue, and the gap filling glue overflowing from the gap is erased, thereby preventing the gap filling glue from entering the side key from the gap around the side key. The method can effectively prevent the joint filling glue from entering the side key, and is economical, simple and easy to implement. To facilitate the reader's understanding of the invention, reference will now be made to specific examples.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for preventing a side key of a terminal device from entering glue according to an embodiment of the present invention, as shown in fig. 2, the method includes the following steps:
s11, adhering a protective film to the side key and the side wall around the side key, wherein one end of the protective film, which is far away from the bottom wall, is positioned on the inner side of the side wall;
in this embodiment, since the gap formed by the side key and the mounting hole is located between the side key and the side wall of the main body, in order to prevent the caulking compound from entering the side key from the gap between the side key and the side wall of the main body, a protective film is adhered to the side key and the side wall of the main body around the side key. In addition, in order to prevent the protective film from contacting the gap between the main body and the screen and damaging the gap filling glue in the gap between the main body and the screen in the subsequent process of tearing off the protective film, one end of the protective film far away from the bottom wall is positioned at the inner side of the side wall, namely one end of the protective film close to the screen mounting surface cannot exceed the range of the side wall.
In some embodiments, the protective film is a polyethylene terephthalate film (PET film), and the PET film has a thickness of 0.04-0.06 mm. When the thickness of the PET film is smaller, the PET film is softer, and cannot fall off easily even if the PET film is adhered to different surfaces, but the PET film is easy to be rubbed and broken by a rubbing machine; when the thickness of the PET film is large, the PET film is likely to fall off after being stuck. Specifically, when the thickness of the protective film is 0.05mm, the protective film has a good adhesion effect and is not easy to fall off. Alternatively, in some embodiments, the elongation at break of the PET film may be 30%, and the tensile strength may be 22N/cm; at the moment, the material has better elasticity and toughness, and is not easy to fall off when being stuck on the surfaces of the keycaps and the side keys.
In some embodiments, in order to increase the bonding strength of the protective film on the keys and the side walls, an adhesive layer is disposed on one side surface of the protective film close to the side keys. The adhesive layer may be any suitable polymer resin, for example, the adhesive layer may be at least one of epoxy resin, polyurethane, silicone resin, acrylic resin, and modified acrylic resin. In order to obtain better bonding effect and ensure that the adhesive layer of the protective film has no residue on the surfaces of the side keys and the side walls after being torn off, in some embodiments of the invention, the adhesive layer may be made of acrylic resin or acrylic resin modified resin.
In some embodiments, the side key further comprises a key cap, and the key cap is received in the mounting hole. The user needs to press the keycap to enable the stroke control sheet of the side key to be compressed inwards to a certain stroke to excite the circuit of the side key, so that the terminal equipment can recognize the key information. In order to determine the pasting position of the protective film, the protective film is a transparent plastic film, and a transparent release film is further arranged on one side of the protective film, which is far away from the surface of the side key. And the release film is also provided with a positioning mark which is used for determining the pasting position of the protective film. The shape and size of the alignment mark match the shape and size of the keycap, for example, when the keycap is square, the alignment mark is also square. When the protective film is pasted on the side key, the positioning mark is aligned with the key cap. Specifically, the positioning mark may be a positioning hole or a positioning pattern, and those skilled in the art can set the positioning mark according to actual needs.
In this embodiment, the release film may be one of a polyethylene film, a polymethacrylic acid film, a polycarbonate film, a polypropylene film, or a polyurethane film. When the protective film is pasted, the positioning hole is aligned to the top of the keycap, and then the protective film is pasted on the surface of the keycap and the surface of the side wall around the keycap. And then, flattening the protective film to enable the protective film to be flatly adhered to the keycap and the side wall of the main body, and then removing the release film.

In this embodiment, the base paper may be made of paper fiber and/or a film.
In some embodiments, in order to make the protective film adhere to the main body more tightly and not fall off the main body easily, the protective film comprises a first adhesion part and a second adhesion part, wherein the first adhesion part is adhered to the side key and the side wall around the side key, and the second adhesion part is adhered to the bottom wall of the mobile phone. Specifically, the number of the second bonding portions is two, and the two second bonding portions are located at two ends of the first bonding portion respectively. In order to reduce the amount of the protective film material, the first adhesive portion and the second adhesive portion may be in the shape of a long strip.
In some embodiments, the protective film is a three-dimensional curved protective film in order to further enable the protective film to be tightly fitted to the side wall and the bottom wall which are in different curved surfaces. And the radian of the three-dimensional curved surface protective film is matched with the radian of the side wall and/or the bottom wall. Optionally, in other embodiments, an accommodating cavity is further disposed on the three-dimensional curved surface protective film, and the accommodating cavity is used for accommodating a keycap of a side key; and the shape and the size of the accommodating cavity are matched with those of the keycap.
