In addition, the technical features involved in different embodiments of the present disclosure described below can be combined with each other as long as they do not conflict with each other.

Refer toFIG. 1, which is a perspective view showing the cooperation of a screen protector applicator100according to an embodiment of the present disclosure and a protector-to-be-applied device200(i.e., a device to which a screen protector is to be applied). An embodiment of the present disclosure provides a screen protector applicator100for assisting the protector-to-be-applied device200to be applied with a screen protector. The protector-to-be-applied device200may be electronic equipment, such as a mobile phone, a tablet computer or the like.

Refer toFIGS. 2 and 3together, whereinFIG. 2is a perspective view of a structure of a tray10of the screen protector applicator100ofFIG. 1, andFIG. 3is a perspective view of a structure of a guide insert pin20of the screen protector applicator100ofFIG. 1. The screen protector applicator100comprises the tray10and the guide insert pin20.

The tray10comprises a frame11, which is roughly rectangular frame-shaped. The middle part of the frame11is provided with an accommodating groove1101adapted to the shape and size of the protector-to-be-applied device200. The accommodating groove1101is roughly rectangular. The accommodating groove1101penetrates the frame11along the thickness direction of the frame11, and the accommodating groove1101is used for accommodating the protector-to-be-applied device200. The frame11includes two oppositely arranged long sides111and two oppositely arranged short sides112. The two long sides111and the two short sides112surround the accommodating groove1101. When the protector-to-be-applied device200is accommodated in the accommodating groove1101, the long sides of the protector-to-be-applied device200are parallel to the long sides111of the frame111, and the short sides of the protector-to-be-applied device200are parallel to the short sides112of the frame111.

The accommodating groove1101penetrates the frame11, so that the protector-to-be-applied device200can be directly placed in the accommodating groove1101of the frame11through any one of notches at both ends of the accommodating groove1101, facilitating the installation between the protector-to-be-applied device200and the frame11. In addition, the accommodating groove1101is adapted to the shape of the protector-to-be-applied device200. Therefore, the accommodating groove1101can also play a role in limiting the protector-to-be-applied device200to a certain extent.

In an embodiment of the present disclosure, the specific structure of the frame11is not limited, and the frame11may also have other structural shapes.

The guide insert pin20comprises a connecting plate21and a guide protrusion22. The connecting plate21is slidably connected to the frame11, and the connecting plate21can slide back and forth relative to the frame11. The guide protrusion22comprises a first protrusion221, which is fixedly connected to the connecting plate21. The first protrusion221is used to extend above the accommodating groove1101to be inserted between the protector-to-be-applied device200and a screen protector. The first protrusion221includes a first inclined surface2211. The first inclined surface2211faces away from the accommodating groove1101. The first inclined surface2211extends along the first protrusion221to above the accommodating groove1101and is inclined in a downward direction, and is arranged at a first angle with a plane where the accommodating groove1101is located. The first inclined surface2211is used to guide the screen protector to gradually detach from the first inclined surface2211and gradually flatly attach to a protector-to-be-applied surface of the protector-to-be-applied device200, which prevents air bubbles from being generated between the protector-to-be-applied surface and the screen protector during the attaching process, thereby ensuring the quality of screen protector application.

In an embodiment of the present disclosure, two guide insert pins20are provided on the two short sides112, respectively, and the two guide insert pins20can slide toward or away from each other relative to the frame11. By providing a guide insert pin20on each of the two short sides112, opposite sides of the screen protector each can be gradually flatly attached to the protector-to-be-applied surface of the protector-to-be-applied device200by pulling away the two guide insert pins20, thereby allowing the air between the protector-to-be-applied surface and the screen protector to be gradually discharged, which can effectively prevent air bubbles from being generated between the protector-to-be-applied surface and the screen protector during the attaching process, thereby ensuring the quality of screen protector application. The first angle formed by the first inclined surface2211of the first protrusion221located on one short side112and the plane where the accommodating groove1101is located has an angle orientation facing away from the other short side112. The size of the first angle can be set according to actual needs as long as it is greater than 0° and less than 90°.

Please refer toFIGS. 4 and 5, whereinFIG. 4is a schematic view of an initial state when two droplets of glue300are dropped on the protector-to-be-applied device200, andFIG. 5is a schematic view of a state when the glue300shown inFIG. 4gradually spreads between the protector-to-be-applied device200and a screen protector, wherein the screen protector is omitted. A specific use process of the screen protector applicator100is exemplified below. When the screen protector is applied, the protector-to-be-applied device200is placed in the accommodating groove1101, the first protrusion221is extended above the accommodating groove1101, and two droplets of glue300are dropped on the protector-to-be-applied surface of the protector-to-be-applied device200. The distances between each droplet of glue300and the two long sides111are roughly the same. The distance between each droplet of glue300and another droplet of glue300is roughly equal to the distance between it and an adjacent short side112, and also roughly equal to the distance between it and each long side111, as shown inFIG. 4. Opposite sides of the screen protector are placed on the first inclined surfaces2211of the two guide insert pins20and located above the protector-to-be-applied device200. The first protrusion221is located between the protector-to-be-applied device200and the screen protector. The opposite sides of the screen protector are placed on the first inclined surfaces2211of the two guide insert pins20, and under the action of gravity, the first inclined surface2211extends along the first protrusion221to above the accommodating groove1101and is inclined in a downward direction, so that the screen protector gradually bends downwards from the opposite sides toward the middle. Since the distances between each droplet of glue300and the two long sides111are roughly the same, and the distance between each droplet of glue300and the other droplet of glue is roughly equal to the distance between it and the adjacent short side112, the two droplets of glue300are located on both sides of the middle of the screen protector. The first protrusion221is gradually pulled away from between the protector-to-be-applied device200and the screen protector, so that the screen protector gradually detaches from the first inclined surface2211, and the both sides adjacent to the middle of the screen protector first come into contact with the two droplets of glue300. As the screen protector gradually detaches from the first inclined surface2211, the screen protector squeezes two droplets of glue300. Moreover, since the two droplets of glue300are located on both sides of the middle of the screen protector, the pressure on each droplet of glue300is greater, so that each droplet of glue300accelerates to spread around. The two droplets of glue first spread to the middle of the screen protector and mix together. Due to the large amount of glue at the mixture point, it will accelerate the squeezing out of the air in the middle of the screen protector, as shown inFIG. 5. After that, glue300gradually spreads to the opposite sides of the screen protector. Because the opposite sides of the screen protector are supported by the first protrusions221of the two guide insert pins20, the opposite sides of the screen protector slightly bend upwards relative to the middle of the screen protector. Therefore, the bend of the screen protector close to the protector-to-be-applied surface of the protector-to-be-applied device200is under greater pressure, which will accelerate the squeezing out of air located on opposite sides of the screen protector. Moreover, under the guidance of the first inclined surface2211, the opposite sides of the screen protector are gradually flatly attached to the protector-to-be-applied surface of the protector-to-be-applied device200from the middle of the screen protector towards the opposite sides of the screen protector during the diffusion of the glue300, and the air on the opposite sides of the screen protector is gradually squeezed out to prevent air bubbles from appearing in the flat attachment process. When the screen protector is completely separated from the first inclined surface2211, the glue300covers the protector-to-be-applied surface of the protector-to-be-applied device200, the air between the protector-to-be-applied surface of the protector-to-be-applied device200and the screen protector is completely discharged, and the screen protector is completely attached to the protector-to-be-applied surface of the protector-to-be-applied device200. Since the distance between each droplet of glue300and another droplet of glue300is roughly equal to the distance between it and the adjacent short side112, and also roughly equal to the distance between it and each long side111, the glue300makes the air between the protector-to-be-applied surface of the protector-to-be-applied device200and the screen protector completely discharged, and when the screen protector is completely attached to the protector-to-be-applied surface of the protector-to-be-applied device200, the glue300will have no or less overflow from the two long sides111.

It can be understood that, when a screen protector is applied, the number of glue droplets on the protector-to-be-applied surface of the protector-to-be-applied device200can be selected according to actual needs, and is not limited to two. It may also be three or more.

In this embodiment, the screen protector applicator100further comprises an adsorbing member, each long side111is provided with a through groove1102, and the through groove1102penetrates the long side111. When the screen protector is applied, the adsorbing member is inserted into the through groove1102. The adsorbing member is used to adsorb the glue overflowing between the protector-to-be-applied device200and the screen protector from the side. The adsorbing member may be a material with adsorbing ability, such as paper and cotton.

Regarding the aforementioned connecting plate21, the connecting plate21comprises a connecting portion211and a push-pull portion212, and two connecting portions211are fixedly connected to opposite sides of the push-pull portion212, respectively.

The connecting portion211is slidably connected to the frame11, and the connecting portion211can slide back and forth relative to the frame11, so that the guide insert pin20can slide back and forth relative to the frame11. As a result, the first protrusion221can be extended above the accommodating groove1101or away from the accommodating groove1101.

In some other embodiments of the present disclosure, the push-pull portion212is slidably connected to the frame11, and the push-pull portion212can slide back and forth relative to the frame11, so that the guide insert pin20can slide back and forth relative to the frame11.

An operator can push and pull the push-pull portion212so that the guide insert pin20slides back and forth relative to the frame11. A side of the push-pull portion212facing away from the frame11is provided with a friction portion2121, and the friction portion2121is used to increase friction force in contact with the push-pull portion212to facilitate the operator to push and pull the push-pull portion212. In this embodiment, the friction portion2121is a plurality of grooves arranged adjacently.

In some other embodiments of the present disclosure, the friction portion2121may be other structures for increasing the friction force in contact with the push-pull portion212, such as protrusions and abrasive sand.

In this embodiment, each guide protrusion22comprises two first protrusions221spaced apart, and the two first protrusions221can jointly support the screen protector, so that a part of the screen protector between the two first protrusions221can bend toward the protector-to-be-applied surface of the protector-to-be-applied device200relative to both sides of the screen protector facing away from the two first protrusions221. In the process of pulling away the guide protrusion22, a part of the screen protector located on the two first protrusions221can be gradually flatly attached to the protector-to-be-applied surface from the middle of the two first protrusions221towards the two first protrusions221, thereby enhancing the guidance of the guide protrusion22to the screen protector and the slow-release effect of the glue when spreading between the screen protector and the protector-to-be-applied device200. The two first protrusions221are fixedly connected to the two connecting portions211, respectively.

In some other embodiments of the present disclosure, the number of the first protrusions221can be selected according to actual needs, and is not limited to two.

In this embodiment, each guide protrusion22further comprises two second protrusions222spaced apart. The second protrusions222are fixedly connected to the connecting plate21, and the two second protrusions222are located between the two first protrusions221. The two second protrusions222support the part of the screen protector between the two first protrusions221to prevent the part of screen protector in the middle of the first protrusion221from collapsing too much and first flatly attaching to the protector-to-be-applied surface of the protector-to-be-applied device200, thereby ensuring that both sides of the screen protector can be slowly and flatly attached to the protector-to-be-applied device200as a whole when pulling away the guide protrusion22. The second protrusion222is provided with a second inclined surface2221. The second inclined surface2221extends along the second protrusion222to above the accommodating groove1101and is inclined in a downward direction. It is arranged at a second angle with the accommodating groove1101, and the second angle is smaller than the first angle to allow the part of the screen protector located between the two first protrusions221to slightly collapse, and be slowly flatly attached to the protector-to-be-applied surface from the middle part of the two first protrusions221towards the two first protrusions221. The two second protrusions222are fixedly connected to surfaces of the two connecting portions211facing away from the accommodating groove1101, respectively, wherein the second angle formed by the second inclined surface2221of the second protrusion222located on one short side112and a plane where the accommodating groove1101is located has an angle orientation facing away from the other short side112. The size of the second angle can be set according to actual needs, as long as it is greater than 0° and less than 90°, and less than the first angle.

In this embodiment, the angle formed by the first inclined surface2221and the surface of the connecting portion211is the first angle, and the angle formed by the second inclined surface2221and the surface of the connecting portion211is the second angle.

In some other embodiments of the present disclosure, the number of the second protrusions222can be selected according to actual needs, and is not limited to two.

Further, each connecting portion211extends out from the push-pull portion212. The two first protrusions221and the two second protrusions222are fixedly connected in pairs to the surfaces of the parts of the two connecting portions211extending out from the push-pull portion212. That is, one first protrusion221and one second protrusion222are fixedly connected to a surface of a part of one connecting portion211extending out from the push-pull portion212that faces away from the accommodating groove1101, and the other first protrusion221and the other second protrusion222are fixedly connected to a surface of a part of the other connecting portion211extending out from the push-pull portion212that faces away from the accommodating groove1101. The first protrusion221and the second protrusion222are provided on the part of the connecting portion211extending out from the push-pull portion212, so that the contact area between the connecting plate21as a whole and the protector-to-be-applied device200can be prevented from being too large to increase friction force, and at the same time, the difficulty of pulling away the guide protrusion22is reduced.

In this embodiment, the length directions of the first protrusions221and the second protrusions222are arranged in parallel with the extension direction of the connecting portion211. The first inclined surface2211entirely covers a side of the first protrusion221facing away from the connecting portion211. The second inclined surface2221entirely covers a side of the second protrusion222facing away from the connecting portion211.

Furthermore, the part of the connecting portion211extending out from the push-pull portion212has an end2111away from the push-pull portion212. The first inclined surface2211is closer to the end2111than the second inclined surface2221. In the extension direction of the connecting portion211, a preset separation distance is left between the end of the first inclined surface2211close to the end2111and the end of the second inclined surface2221close to the end2111, so that the screen protector within the preset distance is closer to the protector-to-be-applied surface of the protector-to-be-applied device200, which is helpful for the screen protector to be slowly attached to the protector-to-be-applied device200from within the preset distance toward the push-pull portion212and toward two sides of the two first protrusions221facing away from each other. The size of the preset distance can be set according to actual needs.

The guide insert pin20further comprises an abutting portion23fixedly connected to the connecting plate21. The tray10further comprises a limiting plate12fixedly connected to the frame11. The abutting portion23is used for abutting against the limiting plate12to limit the movement stroke of the guide insert pin20relative to the tray10, so that the guide protrusion22just extends to a preset position above the accommodating groove1101, preventing the guide insert pin20from sliding into the accommodating groove1101as a whole. The abutting portion23extends from a side of the connecting portion211facing away from the protector-to-be-applied device200towards a direction away from the protector-to-be-applied device200. Two abutting portions23are fixedly connected to the two connecting portions211, respectively.

Refer toFIG. 6, which is a partial enlarged view of part A ofFIG. 2. The tray10is provided with a limiting groove101. The connecting plate21is slidably inserted into the limiting groove101. The limiting groove101is used to limit the sliding direction of the guide insert pin20relative to the tray10, so that the guide protrusion22can be smoothly pulled away from between the protector-to-be-applied device200and the screen protector.

Specifically, two limiting plates12are arranged opposite each other. Each limiting plate12comprises a vertical plate121and a horizontal plate122. One end of the vertical plate121is fixedly connected to the frame11, and one end of the horizontal plate122is fixedly connected to a side wall of the vertical plate121. The vertical plate121, the horizontal plate122and the frame11enclose to form a limiting groove101therebetween. Opposite sides of the connecting plate21are inserted into the limiting grooves101of the two oppositely arranged limiting plates12, respectively. A gap is provided between the connecting plate21and the horizontal plate122. The gap is used to allow the connecting plate21to have a certain inclined sliding space in the limiting groove101, so that the downward inclination angle of the guide protrusion22in the limiting groove101when it extends above the accommodating groove1101can be adjusted according to actual needs, so as to adapt to protector-to-be-applied devices200with different thicknesses. Of course, the connecting plate21may also slide in the limiting groove101in parallel with an upper surface of the protector-to-be-applied device200. The connecting portions211on the opposite sides of the push-pull portion212are each slidably inserted into the limiting groove101on a corresponding limiting plate12.

In some other embodiments of the present disclosure, the limiting groove101may also be directly provided in the frame11, and the connecting plate21is directly slidably connected to the limiting groove101on the frame11.

Preferably, the vertical plate121and the horizontal plate122are arranged perpendicular to each other, and the vertical plate121is perpendicular to the frame11.

The limiting plate12further comprises a baffle123, which is fixedly connected to a side of the horizontal plate122facing away from the limiting groove111. The baffle123is used to block the connecting plate21from passing through and prevent the connecting plate21from extending above the accommodating groove1101from a side of the horizontal plate122facing away from the limiting groove111, so that the connecting plate21between the two opposite limiting plates12can only extend along the limiting groove111above the accommodating groove1101, thereby avoiding the occurrence of maloperation.

Refer toFIG. 7, which is a partial enlarged view of part B ofFIG. 2. The tray10further comprises a limiting protrusion13. A plurality of limiting protrusions13are each fixedly connected to the long side111of the frame11. The limiting protrusion13is used to play a role in limiting the protector-to-be-applied device200, so that the position of the protector-to-be-applied device200relative to the frame11is fixed, thereby facilitating the work of applying the screen protector.

Specifically, the limiting protrusion13is formed to extend from an inner side wall of the long side111of the frame11toward a side wall of the protector-to-be-applied device200. The limiting protrusion13partially extends into the accommodating groove1101. The limiting protrusion13is used to abut against the side wall of the protector-to-be-applied device200to realize the limiting function of the protector-to-be-applied device200. The limiting protrusion13includes a guide surface131perpendicular to the protector-to-be-applied surface of the protector-to-be-applied device200. The guide surface131is used for guiding the screen protector to be placed above the protector-to-be-applied surface of the protector-to-be-applied device200.

The limiting protrusion13further includes an abutting surface132, which is located at the junction of the guide surface132and the bottom of the limiting protrusion13. The abutting surface132is adapted to the face angle of the protector-to-be-applied device200. The shape of the abutting surface132can be set according to the dihedral angle of the protector-to-be-applied device200, and it may be a curved surface, a right-angled surface, etc., to better limit the protector-to-be-applied device200.

In this embodiment, the number of the limiting protrusions13is 4, wherein two limiting protrusions13are located on one long side111of the frame11, and the other two limiting protrusions13are located on the other long side111of the frame11.

In order to ensure the structural reliability of the tray10and the guide insert pin20, the tray10and the guide insert pin20may each be an integrated structure.

In addition, this embodiment further provides a method of applying a screen protector onto a screen of a cell phone by using the screen protector applicator. Specific steps of the method are as follows:

Before the screen protector application, leveling pads may be applied to a side of the cell phone opposite to a protector-to-be-applied surface of the cell phone so that the cell phone remains level, and the protector-to-be-applied surface of the cell phone may be cleaned in any manner known to those skilled in the art.

Next, a user places the tray of the screen protector applicator on the cell phone, so that the protector-to-be-applied surface of the cell phone is located in the accommodating groove of the tray. Then, the user inserts a guide inert pin on each end of the tray. At this time, the connecting plate of the guide insert pin is slidably connected to the frame of the tray. After that, the user may insert an adsorbing member such as paper and cotton into the through groove provided on the long side of the tray. The adsorbing member is used to adsorb the glue overflowing between the cell phone and the screen protector from the side.

Then, the user drops two droplets of glue on the protector-to-be-applied surface of the cell phone, so that the distance between each droplet of glue and one long side of the frame is equal to the distance between the droplet of glue and the other long side of the frame, and the distance between each droplet of glue and the other droplet of glue is equal to the distance between the droplet of glue and an adjacent short side of the frame. After that, the user places a screen protector on the protector-to-be-applied surface of the cell phone, so that opposite sides of the screen protector are placed on the first inclined surfaces of the two guide insert pins, and the guide protrusions are located between the cell phone and the screen protector.

Finally, the user pulls away the two guide insert pins from the tray at the same time. During the process of pulling away the guide insert pins, both ends of the screen protector are gradually flatly attached to the protector-to-be-applied surface of the cell phone, thereby allowing the air between the cell phone and the screen protector to be gradually discharged. As a result, air bubbles can be effectively prevented from being generated between the cell phone and the screen protector during the application process, thereby ensuring the quality of screen protector application. In addition, since the guide insert pin is provided with the first inclined surface, when the first protrusion is gradually pulled away from between the cell phone and the screen protector, the screen protector can be gradually flatly attached to the cell phone along the first inclined surface, further preventing air bubbles from being generated between the cell phone and the screen protector during the application process, thereby further ensuring the quality of screen protector application.
