[0002] In order to protect the screen of a terminal device such as a mobile phone or a tablet, a user usually pastes a protective film such as a tempered film or a soft film on the planar surface of the terminal device, so that the touch screen is not easily scratched. In the process of pasting the film, in order to pursue the flatness of the lines and to prevent air bubbles from being generated, the appearance of the terminal device is kept beautiful. Therefore, a film pasting device is usually used to assist the user in accurate positioning and film pasting, so that the film pasting effect can be improved.

[0003] Some existing film pasting devices use a film pressing piece to extrude the protective film in the length direction, so that the protective film is attached to the screen of the mobile terminal.

[0045] As shown in Figure 1 , Figure 3 , the present embodiment proposes a film pressing structure 200 for film pasting, which is used to connect on a film pasting shell 100 to form a film paster, and the film pasting shell 100 is connected to the protective film 20 to paste the screen of the mobile terminal. The mobile terminal in the present embodiment can be a mobile phone 10, and can also be a tablet computer, an electronic book, a smart watch and other electronic devices. For the convenience of structural description of the present embodiment, the length direction of the mobile phone 10 is the length direction, the width direction is the short side direction, and the thickness direction is the up-down direction. The parts of the film pasting device in the present embodiment are described in the above direction. As shown in Figure 3 , Figure 4 , the film pressing structure for film pasting is used on the film pasting device, and the film pasting device is used to bond the protective film 20 to the screen of the mobile phone 10. The protective film 20 mainly comprises a film pasting layer 24, a positioning release layer 21 and a tear release layer 25. The film pasting layer 24 is used to be attached to the surface of the mobile phone 10, so as to protect the screen of the mobile phone 10; the positioning release layer 21 is detachably arranged on one side of the film pasting layer 24, and the positioning release layer 21 is used to be connected on the film pasting shell. The tear release layer 25 is arranged on the side of the film pasting layer 24 away from the positioning release layer 21, and faces the mobile phone 10. In use, the positioning release layer 21 and the tear release layer 25 are pulled away from the film pasting layer 24, and only the film pasting layer 24 is bonded to the surface of the screen of the mobile phone 10.

[0046] As shown in Figure 1 , Figure 2As shown in the drawings, the embodiment provides a film pressing structure 200 for film pasting, mainly comprising a support frame 210, a plurality of mounting portions 220 and film pressing pieces 250. The support frame 210 is arranged movably on the film pasting shell 100 of a film pasting device along a first direction, the plurality of mounting portions 220 are arranged at intervals on the support frame 210 along the first direction, and the plurality of film pressing pieces 250 can be prepared in advance. The plurality of film pressing pieces 250 can be of different sizes or different structures. According to the size of the mobile phone 10 or the material of the protective film 20, one film pressing piece 250 matched with the mobile phone 10 to be pasted is selected from the film pressing pieces 250 prepared in advance, and the film pressing piece 250 is arranged on one of the plurality of mounting portions 220, so as to press the protective film 20 on the film pasting device by the movement of the support frame 210. The structures of the plurality of mounting portions 220 are the same in some of the mounting portions 220, but different in height, so as to connect the film pressing pieces 250 of different sizes, and the film pasting can be performed on the mobile phone 10 of different specifications. The plurality of mounting portions 220 can also have different structures, so as to connect the film pressing pieces 250 of different structures to adapt to the protective film 20 of different materials.

[0047] As shown in the drawings, Figure 1 , Figure 2 , Figure 3 The film pressing structure 200 for film pasting of the embodiment is provided with the plurality of mounting portions 220 on the support frame 210 of the film pressing structure 200, the plurality of mounting portions 220 are arranged at intervals on the support frame 210 along a first direction, the first direction can be a length direction, and the plurality of mounting portions 220 are used to mount film pressing pieces 250 of different specifications or different types. Before use, the film pressing piece 250 matched with the height size of the mobile phone 10 to be pasted is selected and mounted on one of the plurality of mounting portions 220 corresponding thereto, so as to form the film pressing structure 200. The film pressing structure 200 is connected to the film pasting shell 100 of the film pasting device, and the support frame 210 is pushed to move along the first direction, so that the film pressing piece 250 presses the protective film 20 and pastes on the surface of the mobile phone 10. Therefore, for the mobile phone 10 of different specifications, only the appropriate film pressing piece 250 needs to be selected and mounted on the corresponding mounting portion 220, so as to form the film pressing structure 200 matched with the mobile phone 10 to be pasted, and the support frame 210 can be universal. When the film pressing structure 200 of different specifications is to be produced, only one support frame 210 needs to be produced, which can be universal. In this way, repeated mold opening is avoided, and production cost is saved.

[0048] The mounting portion 220 of the embodiment can adopt various structural forms, which are as follows:

[0049] As shown in the drawings, Figure 1 , Figure 2As shown in Figures (a) and (c), in the first structural form, the plurality of mounting parts 220 include a first mounting part 230, which includes locking positions 231 located at both ends of the support frame 210 in a second direction, which can be the width direction. Specifically, the support frame 210 includes a support cross plate 211 extending along the width direction. The support cross plate 211 has side baffles 212 at both ends in the width direction, and the locking positions 231 on both sides are located inside the side baffles 212. The corresponding film pressing component 250 specifically includes a roller 260, whose two ends are respectively locked into the locking positions 231 at both ends, so that the roller 260 is rotatably mounted on the support frame 210 to roll the protective film 20. Multiple first mounting parts 230 can be provided. The height of the central axis of the card slot 231 on different first mounting parts 230 is different. Therefore, multiple specifications of rollers 260 can be provided. Different specifications of rollers 260 are matched with different first mounting parts 230. After different rollers 260 are installed on first mounting parts 230 with different heights, different pressure film structures 200 are formed to cope with mobile phones 10 with different height specifications.

[0050] like Figure 1 , Figure 3 As shown, the locking position 231 in this embodiment further includes a support platform 232 and locking posts 233. The support platform 232 is located inside the side baffle 212, and a locking groove 234 is formed on the support platform 232, with the opening of the locking groove 234 facing away from the support horizontal plate 211. The locking posts 233 are arranged on the side of the support platform 232 away from the support horizontal plate 211, and are mirror-symmetrical on both sides of the support horizontal plate 211, forming a locking opening of the locking groove 234 between the locking posts 233 on both sides; a central shaft 261 passes through the roller 260, and both ends of the central shaft 261 are respectively locked into the locking groove 234 through the locking opening. The inner wall of the locking opening facing outward is tapered, which facilitates the central shaft 261 at the end of the roller 260 to enter the locking opening and squeeze the locking posts 233 on both sides, causing the locking posts 233 on both sides to deform and widen the outer end of the locking opening, thereby squeezing into the locking groove 234 for connection.

[0051] like Figure 1 , Figure 2As shown in FIG. 2B, in the second structure, the plurality of mounting portions 220 include a second mounting portion 240, which includes a mounting cavity 241 arranged on the support frame 210 and extending in the second direction; the mounting cavity 241 is arranged on the surface of the support plate 211, and the opening of the mounting cavity 241 is located on the side away from the support plate 211. The corresponding film pressing member 250 includes a pressing block 270 clamped in the mounting cavity 241, and the side of the pressing block 270 away from the mounting cavity 241 forms a pressing surface 271 for pressing the protective film 20. The pressing block 270 can be an EVA block, and the end away from the pressing surface 271 can be connected in the mounting cavity 241 by bonding or clamping, and the protective film 20 is pressed by the pressing surface 271. The pressing surface 271 can be linear in the width direction, for applying the film to the flat screen mobile phone 10, and arc surfaces can also be arranged at both ends of the linear surface, so that the film can be applied to the curved screen mobile phone 10. The pressing block 270 can apply the film to the hard film such as tempered glass or the soft plastic film.

[0052] As shown in FIG. 2B, Figure 1 Further, the surface of the support frame 210 of the embodiment is provided with a plurality of inner enclosing baffles 242 connected to enclose the mounting cavity 241. In the specific structure, the inner enclosing baffles 242 are arranged protruding on the surface of the support plate 211, and the inner enclosing baffles 242 can be arranged on four sides in the length direction and the width direction, so as to enclose a square mounting cavity 241. The pressing block 270 is clamped in the mounting cavity 241 and limited by the mounting cavity 241, facilitating installation.

[0053] As shown in FIG. 2B, Figure 1 , Figure 2 The plurality of mounting portions 220 of the embodiment include two first mounting portions 230 and one second mounting portion 240. The two first mounting portions 230 and the second mounting portion 240 are arranged on the support frame 210 in the first direction, the heights of the two first mounting portions 230 are different, and the second mounting portion 240 is located between the two first mounting portions 230. Thus, the film pressing structure 200 of the embodiment can form at least three forms, wherein the first mounting portion 230 with a lower height and the corresponding roller 260 are connected to apply the film to the mobile phone 10 with a thicker thickness or the protective film 20 with a thicker film. The first mounting portion 230 with a higher height and the corresponding roller 260 are connected to apply the film to the mobile phone 10 with a thinner thickness or the protective film 20 with a thinner film. The pressing block 270 is arranged on the second mounting portion 240 to enable the film pressing structure 200 to realize the scraping and pressing function to adapt to the material requirements of different protective films 20.

[0054] Embodiment Two

[0055] As shown in FIG. 2B, Figure 3 ,Figure 4 , Figure 5 As shown, this application also proposes a film applicator, including a film applicator housing 100 and a film pressing structure 200 for applying the film as described above; the film applicator housing 100 is used to limit the mobile terminal to which the film is to be applied and to connect and limit the protective film 20; the film pressing structure 200 is connected to the film applicator housing 100 and moves along a first direction to press the protective film 20 onto the mobile terminal.

[0056] like Figure 3 , Figure 4 As shown, the film-applying shell 100 further includes: a shell 110, an elastic member 130, a first limiting part 140, and a second limiting part 150. The shell 110 is provided with an accommodating cavity 120, which is used to accommodate and limit the mobile terminal to which the film is to be applied. The film-pressing structure 200 is movably connected to the shell 110 along a first direction. The elastic member 130 is located at one end in the longitudinal direction of the accommodating cavity 120. One end of the elastic member 130 is connected to the shell 110, and the other end is movably disposed. The elastic member 130 is provided with the first limiting part 140. The second limiting part 150 is disposed at the other end in the longitudinal direction of the shell 110. The first limiting part 140 and the second limiting part 150 are respectively connected to the protective film 20. Through the support of the elastic member 130, the protective film 20 is connected to and limited on the shell 110 and spaced at a predetermined distance from the mobile terminal in the vertical direction.

[0057] like Figure 3 , Figure 4As shown, in the specific structure, the opening of the accommodating inner cavity 120 faces upward, and a supporting limiting part 121 is arranged in the accommodating inner cavity 120, the supporting limiting part 121 is integrally formed with the shell 110, the supporting limiting part 121 is distributed around the accommodating inner cavity 120 and forms a limiting area, a limiting step is formed on the side of the supporting limiting part 121 facing the limiting area, and the limiting step respectively abuts against the back and the length-width direction side of the mobile phone 10, so as to limit the mobile phone 10 to be pasted with the film. The limiting area surrounded by the supporting limiting parts 121 can be of different sizes, so as to adapt to different mobile phones 10. The elastic piece 130 is located on one side of the length direction of the accommodating inner cavity 120, and one end of the elastic piece 130 facing the center of the accommodating inner cavity 120 is movably suspended, so that the elastic piece 130 has a certain resilience after being extruded by the film pressing structure 200. The end of the elastic piece 130 movably arranged is a movable end, the movable end of the elastic piece 130 extends toward the center side of the accommodating inner cavity 120, and can move downward under extrusion and rebound upward after being not extruded. The first limiting part 140 on the elastic piece 130 is arranged on the outside of the length direction of the mobile phone 10, the first limiting part 140 and the elastic piece 130 can be integrally formed by injection molding, the elastic piece 130 and the shell 110 can be integrally formed by injection molding, and the second limiting part 150 is integrally formed on the other end of the length direction of the shell 110. The two ends of the length direction of the positioning release layer 21 of the protective film 20 are connected through the first limiting part 140 and the second limiting part 150, so that the protective film 20 is positioned above the supporting limiting part 121 and is spaced apart from the mobile phone 10 by a predetermined distance. After the positioning release layer 21 of the protective film 20 is connected to the first limiting part 140 and the second limiting part 150, the entire protective film 20 can be located above the screen of the mobile phone 10, and then the tear release layer 25 of the protective film 20 is torn away from the pasting film layer 24. The tear release layer 25 will contact the screen of the mobile phone 10 in the process of tearing, so as to clean the screen of the mobile phone 10. After the tear release layer 25 is torn away, the pasting film layer 24 and the positioning release layer 21 are still located above the screen under the support of the movable end of the elastic piece 130, so as to avoid the pasting film layer 24 from being in early contact with the screen. The elastic piece 130 is also pressed downward by the film pressing structure 200 during movement, so that the pasting film layer 24 of the protective film 20 can be adhered to the screen of the mobile phone 10 below. During the rebounding process of the elastic piece 130, the positioning release layer 21 is torn away from the pasting film layer 24, which is convenient for the user to finally take the positioning release layer 21 away from the pasting film layer 24.

[0058] As shown in Figure 3 , Figure 5 The film pressing structure 200 can be reversibly arranged at one end (front end) of the length direction of the shell 110, so as to have a side turning state and a film pressing state. Therefore, the pressing roller assembly is turned according to different needs during pasting of the film. As shown in Figure 3 , Figure 4As shown, in the side-tilted state, the pressure member 250 of the pressure film structure 200 flips to the outside of the elastic member 130 in the length direction to avoid the first limiting part 140; as Figure 5 As shown, in the pressure film state, the pressure film member 250 of the pressure film structure 200 flips over to the top of the elastic member 130 and can move along the length direction to compress the protective film 20. This achieves the bonding of the protective film 20. During use, only flipping is required to switch between the side-flipped state and the pressure film state, making the operation simpler and the use more convenient.

[0059] like Figure 3 , Figure 4 , Figure 5 As shown, further, guide grooves 160 are provided on both inner walls of the housing 110 in the width direction, and the guide grooves 160 extend along the length direction. An inlet / outlet 161 and a insertion port 162 are spaced apart on one end of the inner wall of the housing 110 in the length direction. The openings of the inlet / outlet 161 face upwards, and a flip-locking position 163 is formed between the insertion port 162 and the end of the guide groove 160. At least two guide posts 213 are spaced apart on the outer wall of the support frame 210 in the length direction, specifically two guide posts 213 are provided on the outer walls of the side baffles 212 on both sides in the width direction. When the guide posts 213 on the support frame 210 enter the guide groove 160 through the inlet / outlet 161 and the insertion port 162 respectively, one guide post 213 is located on the flip-locking position 163 as a rotation axis, causing the other guide post 213 to rotate out from the inlet / outlet 161, thereby flipping the pressure film structure 200 from above the elastic member 130 to the outside of the elastic member 130.

[0060] like Figure 3 , Figure 4 , Figure 5 As shown, in the specific structure, the guide groove 160 provided on the inner side of the housing 110 allows the support frame 210 to slide within the guide groove 160 via two guide posts 213, enabling the pressure film structure 200 to move stably in a directional manner. The insertion port 162 is located near the front end of the housing 110, so the flip-lock position 163 is located at the front end of the guide groove 160. The two guide posts 213 enter the guide groove 160 from the inlet / outlet 161 and the insertion port 162, respectively. When the support frame 210 moves to the front end of the guide groove 160, one of the guide posts 213, located on the flip-lock position 163, acts as a rotation axis, causing the other guide post 213 to rotate out from the inlet / outlet 161, thereby flipping the sliding frame from above the housing 110. When the phone is flipped over, it is not necessary to remove the entire sliding bracket when taking out the phone after applying the screen protector; and before connecting the screen protector 20, the space above the first limiting part 140 can be made by flipping the phone over, making it easier to connect the screen protector 20 to the first limiting part 140.
