[0002] Electronic devices such as mobile phones and tablet computers are increasingly used in our daily lives. During use, the surface of the electronic device (such as the screen or other surfaces) is often easily scratched, which affects the quality of use. In order to prevent this phenomenon from happening, users often stick a layer of protective film on the surface of the electronic device.

[0003] However, in most cases, the film application process is to manually tear off the outer protective layer of the protective film assembly and then apply the film. The operation steps are complicated and the film application process cannot be completed in one step. Moreover, since the entire film application process is not completed in one go, it is difficult to ensure that the film application environment is dust-free. In the gap between completely tearing off the outer protective layer and completing the film application, dust may enter between the electronic device and the protective film body, and it is easy to cause bubbles, which will affect the film application effect and normal use. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention innovatively provides a film sticking device, which releases mechanical energy through a force storage component to provide driving force, driving the sliding seat to slide the electronic device and the protective film body toward the rear end of the base.

Since the first protective film 21 is connected to the sliding seat 3 through the first positioning portion 211, when the sliding seat 3 slides toward the rear end of the base 1, the sliding seat 3 slides toward the rear end of the base 1 with the electronic device 20, the protective film body 22 and the first protective film 21; since the second protective film 23 is connected to the base 1 through the second positioning portion 231, when the sliding seat 3 slides toward the rear end of the base 1 with the electronic device 20, the protective film body 22 and the first protective film 21, the second protective film 23 is gradually torn off the protective film body 22, and the protective film body 22 falls on the surface of the electronic device 20 under the action of gravity, as shown in FIG. Figure 6 In the state shown, the film can be automatically torn off and pasted at the same time, completing the film pasting operation in one step.

[0060] Moreover, after the second protective film 23 is torn off, the protective film body 22 immediately falls on the surface of the electronic device 20, which can prevent dust from entering between the electronic device 20 and the protective film body 22, reduce bubbles, and improve the quality of film application.

[0061] In order to prevent the sliding seat 3 from completely sliding out of the base 1, a limiter may be provided to limit the sliding travel of the sliding seat 3.

Figure 4As shown, the second stopper 36 is a convex structure arranged on the bottom surface of the sliding seat 3, the first stopper 16 is located at the rear of the base 1, and the second stopper 36 is located at the front of the sliding seat 3. When the second stopper 36 slides with the sliding seat 3 to the first stopper 16, the sliding of the sliding seat 3 can be stopped by the contact and cooperation between the first stopper 16 and the second stopper 36. By limiting the sliding stroke of the sliding seat 3, it can be ensured that the second protective film 23 is completely torn off and the protective film body 22 is attached to the surface of the electronic device 20, and the film is attached. Preferably, when there are two sliding members 34 and they are distributed on the two side walls of the sliding seat 3, the second stopper 36 can be arranged at the center position of the width direction of the sliding seat 3, and the first stopper 16 is arranged at the center position of the width direction of the base 1. In this embodiment, the front end of the first limit member 16 is a vertical panel perpendicular to the upper surface of the base 1 and the rear end is an inclined panel extending toward the vertical panel, the front end of the second limit member 36 is an inclined panel extending downward and the rear end is a vertical panel, when the second limit member 36 moves with the sliding seat 3 until the vertical panel at the rear end of the second limit member 36 is in contact with the vertical panel at the front end of the first limit member 16, the sliding seat 3 no longer slides outward from the base 1.

[0062] Another optional limiting method is: when one of the sliding guide 14 and the sliding member 34 is a slider, a limiting plate can be set at the end of the slide groove or slide rail that matches the slider to prevent the slider from sliding further, thereby limiting the sliding stroke of the slider; when the slide groove or slide rail is set on the base 1, the limiting plate is set at the rear end of the slide groove or slide rail; when the slide groove or slide rail is set on the sliding seat 3, the limiting plate is set at the front end of the slide groove or slide rail. When the sliding seat 3 slides until the slider contacts the limiting plate, it can no longer slide, thereby limiting the sliding stroke of the sliding seat 3.

[0063] Optionally, the driving mechanism 4 includes a force storage component 41, a gear 42, and a rack 43 meshing with the gear 42, one of which is disposed on the sliding seat 3 and the other on the base 1. The gear 42 may be disposed at the bottom of the sliding seat 3, and the rack 43 may be disposed in the receiving groove 11 of the base 1; the gear 42 may also be disposed in the receiving groove 11 of the base 1, and the rack 43 may be disposed at the bottom of the sliding seat 3. In this embodiment, as Figure 4 As shown, the rack 43 is fixed to the bottom of the sliding seat 3, as shown in FIG. Figure 7 As shown, the gear 42 is arranged in the receiving groove 11 of the base 1. The power storage component 41 is connected with the gear 42 and cooperates to store or release mechanical energy. When releasing mechanical energy, the power storage component 41 can drive the gear 42 to rotate. When the sliding seat 3 is completely on the base 1, the power storage component 41 is in an energy storage state.

[0064] Further, the force storage component 41 is a coil spring, and a core shaft 12 is provided on the base 1 or the sliding seat 3 where the gear 42 is located. When the gear 42 is provided on the sliding seat 3, a core shaft 12 is provided at the bottom of the sliding seat 3, and the core shaft 12 is close to the front end of the sliding seat 3. Figure 2 and 7 As shown, when the gear 42 is arranged on the base 1, a core shaft 12 is arranged in the receiving groove 11 of the base 1, and the core shaft 12 is close to the rear end of the base 1. The inner end of the coil spring is fixed on the core shaft 12, the coil spring can be wound on the core shaft 12, and the outer end of the coil spring is fixedly connected to the gear 42. A receiving hole for accommodating the coil spring can be provided on the gear 42, and the coil spring can be arranged inside the receiving hole of the gear 42; the gear 42 can also be arranged on one of the end faces of the gear 42. In this embodiment, the gear 42 is a spur gear. In order to ensure the stability of the driving mechanism 4, the gear 42 is rotatably connected to the base 1 or the sliding seat 3 where it is located through a bearing. The bearing is arranged between the gear 42 and the base 1 or the sliding seat 3 where it is located and is coaxially arranged with the gear 42. One of the inner ring and the outer ring of the bearing is fixedly connected to the gear 42, and the other is fixedly connected to the base 1 or the sliding seat 3. When the sliding seat 3 slides toward the front end of the base 1, the gear 42 rotates to drive the coil spring to shrink and wrap around the core shaft 12 to accumulate mechanical energy; when the coil spring recovers its deformation and releases mechanical energy, it drives the gear 42 to rotate in the opposite direction to drive the sliding seat 3 to slide with the electronic device 20 toward the rear end of the base 1. When the sliding seat 3 is completely on the base 1, the coil spring is in an energy storage state. When the force storage component 41 is triggered, the coil spring releases mechanical energy to drive the gear 42 to rotate. Through the meshing connection between the gear 42 and the rack 43, the sliding seat 3 can slide stably toward the rear end of the base 1. After the film is applied, the sliding seat 3 can be pushed into the base 1. During the movement of the sliding seat 3 toward the front end of the receiving groove 11, the gear 42 rotates and the coil spring continuously accumulates mechanical energy. When the sliding seat 3 returns to the receiving groove 11 of the base 1, the coil spring returns to the energy storage state to prepare for the next film application, thereby realizing the reuse of the film application device.

[0065] In order to improve the sliding stability, such as Figure 4 and Figure 7 As shown, the driving mechanism 4 includes two groups of force storage components 41, namely, two gears 42 and two racks 43 are provided. The two racks 43 are arranged opposite to each other and symmetrically arranged on the bottom surface of the sliding seat 3 or in the receiving groove 11 of the base 1. The two gears 42 are arranged between the two racks 43. The gears 42 and the racks 43 are meshed and connected one by one. Each gear 42 is connected to a coil spring. When the sliding seat 3 slides toward the front end of the base 1, the two coil springs accumulate mechanical energy at the same time; when the two coil springs release mechanical energy, the sliding seat 3 is driven to slide toward the rear end of the base 1. At this time, if the number of the sliding guide 14 and the sliding member 34 is one, the sliding assembly can be arranged between the two gears 42.

[0066] In another optional embodiment, the driving mechanism 4 only includes a force storage component 41, which is a compression type elastic element. The compression type elastic element is arranged in front of the sliding seat 3, and the compression type elastic element abuts between the sliding seat 3 and the base 1. The elastic deformation direction of the compression type elastic element is along the front-to-back direction. When the sliding seat 3 slides toward the front end of the base 1, the compression type elastic element is compressed. Specifically, the front end of the compression type elastic element is fixedly connected to the front end inner wall of the receiving groove 11 of the base 1, and the rear end of the compression type elastic element is fixedly connected to the front end front wall of the sliding seat 3. When the sliding seat 3 is completely in the receiving groove 11 on the base 1, the compression type elastic element is in a compressed state. After the force storage component 41 is triggered, the compression type elastic element is released from compression. Under the action of the restoring elastic force of the compression type elastic element, the sliding seat 3 is pushed to slide toward the rear end of the base 1. The compression type elastic element can be a spring or a spring. The arrangement of the compression type elastic element makes the structure of the driving mechanism 4 simpler, and the length and stiffness of the compression type elastic element can limit the sliding stroke of the sliding seat 3 sliding toward the rear end of the base 1. When the compression type elastic element returns to the natural state, the film tearing and film sticking are just completed. In order to ensure that the sliding seat 3 slides smoothly, the sliding damping can be increased, for example, by arranging a damping member between the sliding guide 14 and the sliding member 34 or by using a damping material for the sliding guide 14 and the sliding member 34 to increase the damping, so as to avoid the sliding seat 3 from sliding too fast, thereby ensuring the film sticking effect.

[0067] By setting the force storage component 41, the present application can simultaneously realize film tearing and film sticking only by triggering the force storage component 41, thereby realizing semi-automation of the film sticking operation, simplifying the operation, and improving the film sticking efficiency.

[0068] The film sticking device of the present application also includes a locking mechanism 5 for locking the sliding seat 3 on the base 1 and a triggering mechanism 6 for triggering the force storage component 41 to release mechanical energy. The locking mechanism 5 includes a first locking member 51 arranged on the front end of the base 1 and a second locking member 52 arranged on the front end of the sliding seat 3. The first locking member 51 and the second locking member 52 can be locked to lock the sliding seat 3 on the base 1; the triggering mechanism 6 is used to release the lock of the first locking member 51 and the second locking member 52, thereby triggering the force storage component 41 to release mechanical energy, providing driving force for the driving mechanism 4, and driving the sliding seat 3 to slide toward the rear end of the base 1. The number of locking mechanisms 5 can be one, the first locking member 51 is arranged at the center of the front width direction of the base 1, and the second locking member 52 is arranged at the center of the front width direction of the sliding seat 3. The number of locking mechanisms 5 can also be two, and the two second locking members 52 are respectively arranged on both sides of the front end of the sliding seat 3. The position of the first locking member 51 corresponds to the position of the second locking member 52, and the locking mechanism 5 does not affect the setting of the sliding assembly. Preferably, as Figure 7 and Figure 8 As shown, the number of the locking mechanism 5 is one.

[0069] Optionally, the first locking member 51 and the second locking member 52 are hooked and locked. The first locking member 51 is a draw hook, and the second locking member 52 is a draw hook, a pull ring or a groove provided at the bottom of the sliding seat 3 that cooperates with the first locking member 51. Figure 7 and Figure 8 As shown, the first locking member 51 is a hook disposed at the front end of the receiving groove 11 of the base 1, with the hook head facing upward, and the second locking member 52 is a groove (notch facing downward) disposed at the bottom of the front end of the sliding seat 3, a hook (hook head facing downward) or a pull ring (pull ring disposed horizontally) matched with the first locking member 51 disposed on the front wall or the bottom of the front end of the sliding seat 3. The hook head of the first locking member 51 can hook the second locking member 52 to lock the sliding seat 3 on the base 1.

[0070] Optionally, the first locking member 51 and the second locking member 52 are magnetically locked. The first locking member 51 and the second locking member 52 are magnetic members that are magnetically attracted to each other. The first locking member 51 is fixed to the front end of the receiving groove 11 of the base 1, with the magnetic surface of the first locking member 51 facing upward, and the second locking member 52 is fixed to the front bottom of the sliding seat 3, with the magnetic surface of the second locking member 52 facing downward, and the second locking member 52 is above the first locking member 51. When the sliding seat 3 slides to the front end of the receiving groove 11 of the base 1, the first locking member 51 and the second locking member 52 are magnetically fixed to lock the sliding seat 3 on the base 1. The first locking member 51 and the second locking member 52 may both be magnetic; one of the first locking member 51 and the second locking member 52 may also be a magnet, and the other may be an iron structure.

[0071] The trigger mechanism 6 includes a compression type elastic member, which is arranged on the base 1. The bottom of the compression type elastic member is fixedly connected to the base 1. The compression type elastic member can be vertically fixed to the front end of the base 1 and is located in the receiving groove 11. The top of the compression type elastic member extends to the top of the base 1. The side of the compression type elastic member is connected to the first locking member 51, which is arranged in the middle and upper part of the compression type elastic member. When the compression type elastic member is triggered and compressed, it drives the first locking member 51 to move downward and away from the second locking member 52 to release the locking of the first locking member 51 and the second locking member 52, so that the force storage component 41 releases mechanical energy to provide driving force for the driving mechanism 4.

[0072] In another possible embodiment, Figure 7 and Figure 8 As shown, the trigger mechanism 6 includes a compression type elastic member, a button 61 and a guide cylinder 62. The guide cylinder 62 is fixed on the base 1, and the compression type elastic member is fixed in the guide cylinder 62. Figure 8As shown, the bottom of the guide cylinder 62 is in a closed state, which can be closed by itself or by the base 1. The bottom of the compression type elastic member is fixedly connected to the bottom of the guide cylinder 62 or the base 1. The button 61 is fixed to the top of the compression type elastic member. The lower part of the button 61 is in the guide cylinder 62 and can slide up and down relative to the guide cylinder 62. The top of the button 61 extends to the top of the base 1 for the hand to press. When the button 61 is pressed downward, the compression type elastic member is compressed. The side of the button 61 is fixedly connected to the first locking member 51. An opening is provided on the side wall of the guide cylinder 62 for the first locking member 51 to slide up and down with the button 61. The first locking member 51 extends through the opening to the outside of the guide cylinder 62. The contact between the first locking member 51 and the upper edge of the opening also limits the travel of the button 61 to slide downward when pressed. The compression type elastic member can be a spring or a spring sheet, the bottom end of the spring or spring sheet is fixedly connected to the bottom of the guide cylinder 62 or the base 1, and the top end of the spring or spring sheet is fixedly connected to the bottom end of the button 61. The button 61 and the guide cylinder 62 are slidably connected through a slide groove and a convex strip matched with the slide groove. The inner wall of the guide cylinder 62 and the outer wall of the button 61 are provided with a convex strip, and the other is provided with a slide groove. When the button 61 is triggered and pressed, the compression type elastic member is compressed, and the button 61 drives the first locking member 51 to move downward and away from the second locking member 52 to release the locking of the first locking member 51 and the second locking member 52, so that the force storage component 41 releases mechanical energy to provide driving force for the driving mechanism 4. After the pressing is released, the restoring elastic force of the compression type elastic member resets the button 61. The guide cylinder 62 plays a guiding role, so that the up and down movement of the button 61 and the compression deformation of the compression type elastic member are more stable; the setting of the button 61 makes the operator press more comfortable and aesthetically pleasing.

[0073] Preferably, if Figure 7 and Figure 8 As shown, when the first locking member 51 is a hook, a first inclined surface 511 is provided on the side of the first locking member 51 close to the sliding seat 3, and the first inclined surface 511 is inclined from top to bottom toward the direction close to the sliding seat 3, as shown in FIG. Figure 4 As shown, a second inclined surface 521 matching the first inclined surface 511 is provided on the outer wall of the second locking member 52. When the sliding seat 3 slides toward the front end of the base 1, the second inclined surface 521 abuts against the first inclined surface 511 and presses the first locking member 51, and the first locking member 51 moves downward to compress the compression type elastic member, and the sliding seat 3 continues to slide toward the front end of the base 1, and the first inclined surface 511 slides downward along the second inclined surface 521 until the hook head of the pull hook hooks the second locking member 52, and the compression type elastic member resets, so that the first locking member 51 stably hooks the second locking member 52, and the sliding seat 3 is locked in the base 1.

[0074] The compression elastic member can not only realize the stable locking of the first locking member 51 and the second locking member 52, but also can efficiently release the locking of the first locking member 51 and the second locking member 52, so that the operator has a more comfortable pressing experience.

[0075] When the sliding seat 3 is completely in the receiving groove 11 of the base 1, the first locking member 51 and the second locking member 52 are locked to lock the sliding seat 3 on the base 1. At this time, the force storage component 41 is in the energy storage state, and the electronic device 20 can be placed in the receiving chamber 31 of the sliding seat 3, with the surface of the electronic device 20 to be filmed facing upward, and the protective film assembly 2 is placed on the surface of the electronic device 20 to be filmed. The protective film assembly 2 is positioned by connecting the first positioning portion 211 with the sliding seat 3 and the second positioning portion 231 with the base 1, and then the protective film body 22 is aligned with the surface of the electronic device 20 to be filmed. The button 61 or the compression elastic member is pressed, and the first locking member 51 moves downward away from the second locking member 52. The first locking member 51 is no longer locked with the second locking member 52 on the sliding seat 3, and the force storage component 41 releases mechanical energy to drive the gear 42 to rotate or restore its natural length, driving the sliding seat 3 to slide toward the rear end of the base 1. The film tearing and film sticking can be completed simultaneously by only pressing the button 61 or the compression elastic member triggering the force storage component 41, thereby realizing the semi-automatic film sticking operation.

[0076] In some embodiments, the film sticking device further includes a pressing roller 7, such as Figure 7 As shown, the pressing roller 7 is rotatably arranged at the rear end of the base 1 and is located above the accommodating chamber 31, and is used to roll the protective film body 22 when the sliding seat 3 slides toward the rear end of the base 1, and press the protective film body 22 to fit the surface of the electronic device 20 to avoid the generation of bubbles. Specifically, an inverted U-shaped bracket 13 is provided above the rear end accommodating groove 11 of the base 1, and the pressing roller 7 is arranged inside the bracket 13 and is rotatably connected to the bracket 13. When the sliding seat 3 carries the electronic device 20, the protective film body 22 and the first protective film 21 to slide toward the rear end of the base 1, the pressing roller 7 is driven to rotate, and the pressing roller 7 rolls and presses the protective film body 22 to eliminate bubbles and fit the protective film body 22 to the surface of the electronic device 20.

[0077] When the sliding seat 3 slides toward the front end of the base 1 , the sliding seat 3 is locked by the locking mechanism 5 when the accommodating chamber 31 is located in front of the pressing roller 7 .

[0078] In some embodiments, the film sticking device further includes a dirt removal roller 8, which is rotatably disposed at the rear end of the base 1 and located above the accommodating chamber 31, and is used to roll and remove dirt and dust on the electronic device 20 when the sliding base 3 slides toward the rear end of the base 1. Figure 7 and Fig. 9As shown, the dirt removal roller 8 can also be rotatably arranged inside the bracket 13 on the base 1, and the dirt removal roller 8 is arranged in front of the pressing roller 7. The lower part of the dirt removal roller 8 can contact the electronic device 20, and the upper part of the dirt removal roller 8 can contact the second protective film 23. When the sliding seat 3 slides toward the rear end of the base 1, the dirt removal roller 8 rotates, and the electronic device 20 contacts the dirt removal roller 8 in sequence from the rear end to the front end, thereby achieving rolling dirt removal.

[0079] Alternatively, if Fig. 9 As shown, the dirt removal roller 8 is rotatably connected to the base 1 through a torsion spring 9. A torsion spring 9 is respectively provided at both ends of the dirt removal roller 8. The two ends of the dirt removal roller 8 are respectively rotatably sleeved in the corresponding torsion spring 9. The two ends of the torsion spring 9 are arranged up and down to be respectively fixedly connected to the base 1. Specifically, one end of the torsion spring 9 is fixedly connected to the top plate of the bracket 13 of the base 1. A card slot 131 can be provided on the top plate of the bracket 13. The end of the torsion spring 9 is inserted into the card slot 131. The side plate of the bracket 13 is provided with a plug hole 132. The other end of the torsion spring 9 is inserted into the plug hole 132. Two torsion springs 9 are distributed on both sides of the bracket 13. The two ends of the dirt removal roller 8 are respectively inserted into the corresponding torsion spring 9, and the dirt removal roller 8 can rotate in the torsion spring 9. The provision of the torsion spring 9 can make the dirt removal roller 8 be subjected to elastic downward pressure, ensure the fit between the dirt removal roller 8 and the electronic device 20, press the wheel surface of the dirt removal roller 8 on the electronic device 20, and ensure the dirt removal effect.

[0080] In some embodiments, the decontamination roller 8 includes an elastic roller and alcohol-absorbing cotton wrapped on the elastic roller. An alcohol chamber is provided inside the elastic roller, and alcohol is stored in the alcohol chamber. A through hole connected to the alcohol chamber is provided on the axial surface of the elastic roller. The two ends of the elastic roller are respectively inserted into two torsion springs 9, and the alcohol chamber and the alcohol-absorbing cotton are located between the two torsion springs 9. Preferably, the length of the alcohol chamber along the axial direction of the elastic roller and the length of the alcohol-absorbing cotton along the axial direction of the elastic roller are greater than or equal to the width of the surface of the electronic device 20 to be filmed, and the through hole is initially in a closed state to prevent alcohol from volatilizing. When the sliding seat 3 slides toward the rear end of the base 1, the elastic roller is squeezed by the electronic device 20 while rotating, and the through hole opens to release alcohol. Alcohol flows out of the alcohol chamber and is absorbed into the alcohol-absorbing cotton. The alcohol-absorbing cotton adsorbed with alcohol rolls to wipe away dust and other impurities on the electronic device 20. In addition, alcohol is volatile and does not affect the bonding effect between the protective film body 22 and the electronic device 20.

[0081] Preferably, the elastic roller can be made of rubber material, and the alcohol absorption cotton can be sponge.

[0082] In another possible embodiment, the dirt-removing roller 8 includes a roller and a multi-layer dirt-removing adhesive tape arranged on the roller. The two ends of the roller are respectively inserted into the corresponding torsion springs 9, and the dirt-removing adhesive tape is between the two torsion springs 9. The length of the dirt-removing adhesive tape along the axial direction of the roller is greater than or equal to the width of the surface of the electronic device 20 to be filmed. When the sliding seat 3 slides toward the rear end of the base 1, the outermost dirt-removing adhesive tape rolls to remove dust and other impurities on the surface of the electronic device 20. After one film is pasted, the outermost dirt-removing adhesive tape with impurities can be torn off, and the next layer of dirt-removing adhesive tape will be used for the next film pasting, so that the dirt-removing roller 8 can be used multiple times. The viscosity of the dirt-removing adhesive tape is set according to needs, and it is necessary to ensure that it does not affect the tearing of the second protective film 23.

[0083] When the film sticking device is provided with both a pressing roller 7 and a dirt removal roller 8, when the sliding seat 3 slides toward the front end of the base 1, the sliding seat 3 is locked by the locking mechanism 5 when the end of the accommodating chamber 31 is directly below or in front of the dirt removal roller 8. Preferably, the sliding seat 3 is locked by the locking mechanism 5 when the end of the accommodating chamber 31 is directly below the dirt removal roller 8, that is, in the initial state, the dirt removal roller 8 is just at the rear end of the electronic device 20, and dirt removal starts from the rear end of the electronic device 20. When the protective film assembly 2 is placed on the surface of the electronic device 20, the rear end of the second protective film 23 is above the dirt removal roller 8, the first positioning portion 211 passes over the dirt removal roller 8 and then passes from the bottom of the pressing roller 7 to the rear of the pressing roller 7 to connect with the sliding seat 3, and the pressing roller 7 is above the rear end of the protective film assembly 2. When the sliding seat 3 slides toward the rear end of the base 1 , the dirt removing roller 8 is always located below the second protective film 23 to avoid contacting the protective film body 22 and affecting the stickiness of the protective film body 22 .

[0084] In some embodiments, Fig.10As shown, the film laminating device of the present application is also provided with a protective cover 10, which can be covered on the base 1. The protective cover 10 is connected to the base 1, and the sliding seat 3 is located in the space enclosed by the protective cover 10 and the base 1. The protective cover 10 plays a protective role when the film laminating device is not in use, and is used to protect the internal structures such as the sliding seat 3 and the driving mechanism 4, and can also be used to prevent dust and water. The protective cover 10 can be detachably connected to the base 1, for example, by means of a protrusion and a groove snap-in connection, and the protective cover 10 can be removed when applying the film; it can also be hinged on one side, preferably, the front end of the base 1 is hinged to the protective cover 10, and when applying the film, the protective cover 10 is rotated toward the front end of the base 1 to open; the protective cover 10 and the base 1 can also be connected by a through hole and a convex column, two opposite convex columns are provided on the front end side wall of the base 1, and the front end of the protective cover 10 is provided with a through hole, and the protective cover 10 is sleeved on the convex column through the through hole and can rotate around the convex column, and when applying the film, the protective cover 10 rotates around the convex column to open in front of the base 1. This application does not specifically limit the specific connection method between the protective cover 10 and the base 1, as long as it can be opened when applying the film and does not affect the film application.

[0085] One of the film sticking methods using the film sticking device of the present application is:

[0086] In the case of a protective cover 10, the protective cover 10 is first opened to expose the base 1 and the sliding seat 3. In the case of no protective cover 10, subsequent operations can be performed directly. In the initial state, the sliding seat 3 is inside the receiving groove 11 of the base 1, at which time the force storage component 41 is in the energy storage state, and the first locking member 51 is locked with the second locking member 52 on the sliding seat 3. The electronic device 20 is placed in the accommodating compartment 31 of the sliding seat 3 to achieve the positioning of the electronic device 20, and the surface of the electronic device 20 to be filmed faces upward. The protective film assembly 2 is placed on the electronic device 20, and the rear end of the second protective film 23 is placed above the dirt removal roller 8, and the dirt removal roller 8 is just above the rear end of the electronic device 20 and below the rear end of the second protective film 23. The first positioning portion 211 passes through the bottom of the pressing roller 7 and extends to the rear end of the sliding seat 3. The first positioning portion 211 is connected to the rear end of the sliding seat 3, and the second positioning portion 231 is connected to the front end of the base 1, thereby achieving the positioning of the protective film assembly 2. Pressing the button 61 or the compression elastic member downward triggers the force storage component 41, the first locking component 51 is unlocked from the second locking component 52 on the sliding seat 3, and the force storage component 41 releases mechanical energy, driving the sliding seat 3 to slide outward from the base 1, and the sliding seat 3 carries the electronic device 20, the protective film body 22 and the first protective film 21 to move toward the rear end of the base 1. Since the second positioning portion 231 is connected to the base 1, as the sliding seat 3 slides, the second protective film 23 is gradually torn off from the rear end to the front end of the protective film body 22; during the sliding process of the sliding seat 3, the dirt removal roller 8 rolls, and the electronic device 20 contacts the dirt removal roller 8 from the rear end to the front end in turn to achieve dirt removal; the pressing roller 7 rolls, and the protective film body 22 is rolled by the pressing roller 7 from the rear end to the front end in turn, and the protective film body 22 is pressed and attached to the surface of the electronic device 20 to avoid bubbles. Until the second limiter 36 moves to the position of the first limiter 16, the sliding seat 3 stops sliding and the film is attached. At this time, remove the electronic device 20 with the protective film body 22 and the first protective film 21 attached, and tear off the first protective film 21 to complete the film application. The entire film application process is simple to operate, and the film can be torn off and applied at the same time, and the dirt removal and pressing of the film are achieved at the same time, avoiding the dust and bubbles from affecting the film application effect, greatly improving the film application efficiency and film application quality. And through the positioning function of the first positioning part 211 and the second positioning part 231, the problem of skewed film application is avoided.

[0087] After the film application is completed, the sliding seat 3 can be pushed toward the front end of the base 1. During this process, the force storage component 41 continuously accumulates mechanical energy until the sliding seat 3 slides to make the end of the accommodating chamber 31 directly below or in front of the dirt removal roller 8. The first locking member 51 is locked with the second locking member 52 on the sliding seat 3, locking the sliding seat 3 in the accommodating groove 11 of the base 1, ready for the next film application. The film application device is reused.
