[0043] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0044] 1 and 2 , a film-applying device according to an embodiment of the present application is used to assist a user in applying a film to the screen of an electronic device 500. The film-applying device according to the embodiment of the present application includes a positioning mechanism and a film assembly 400. The positioning mechanism is used to assist in positioning the screen of the electronic device 500 before applying the film. The film assembly 400 includes a protective film 420 for being attached to the screen of the electronic device 500. It is understood that the electronic device 500 includes but is not limited to mobile phones, tablet computers, and the like. In addition to being used to apply a film to the screen of the electronic device 500, the film-applying device according to the embodiment of the present application can also be used to apply a film to locations such as the back cover of the electronic device 500, which is not specifically limited here.

[0045] 2 and 3 , the positioning mechanism of an embodiment of the present application includes a first mounting seat 100, a second mounting seat 200, and an elastic element 300. The first mounting seat 100 is provided with a first groove 110, which can be used to accommodate the electronic device 500. A first wall 120 is provided on one side of the first groove 110. The second mounting seat 200 is configured to move in a direction approaching or away from the first wall 120, that is, to move in the front-to-back direction in FIG2 ; of course, the first mounting seat 100 and the second mounting seat 200 can also be designed to move in the front-to-back direction in FIG2 . To facilitate understanding of the embodiment of the present application, the following description will be based on the direction in which the second mounting seat 200 approaches or moves away from the first wall 120 as an example of the front-to-back direction. The second mounting seat 200 is provided with a second wall 220 arranged opposite to the first wall 120. The first wall 120 and the second wall 220 are arranged opposite to each other in the direction in which the second mounting seat 200 approaches or moves away from the first mounting seat 100. The elastic element 300 is configured to provide an elastic force that brings the first wall surface 120 and the second wall surface 220 closer together. It is understood that the elastic element 300 can be installed on the first mounting seat 100 and the second mounting seat 200 to provide an elastic force in the front-to-back direction. This elastic force enables the first mounting seat 100 and the second mounting seat 200 to move closer together, thereby exerting a preload force on the first wall surface 120 and the second wall surface 220 to move closer together.

[0046] 2 and 3 , a positioning mechanism according to an embodiment of the present application is provided in which the second mounting seat 200 is further provided with a second groove 210. The first groove 110 and the second groove 210 are connected to form a housing chamber for accommodating the electronic device 500. The first wall 120 and the second wall 220 are respectively located on either side of the housing chamber in the front-to-back direction. Under the action of the elastic element 300, the housing chamber can extend between the first wall 120 and the second wall 220, thereby adapting to the front-to-back dimensions of the electronic device 500. Specifically, the first wall 120 and the second wall 220 are respectively used to abut against two opposite side walls of the electronic device 500. During actual use, the user can first press one of the front side walls or the rear side walls of the electronic device 500 against the first wall 120 or the second wall 220, and then press the electronic device 500 inward to make the other side wall open the accommodating cavity, and finally place the electronic device 500 as a whole into the accommodating cavity and clamp it simultaneously by the first wall 120 and the second wall 220; the user can also first manually move the first mounting seat 100 and the second mounting seat 200 in directions away from each other to open the accommodating cavity, and then place the electronic device 500 into the accommodating cavity, and finally release the hand until the first wall 120 and the second wall 220 clamp the electronic device 500.

[0047] Referring to Figures 11 and 12 , another embodiment of the positioning mechanism of the present application is shown. A second mounting seat 200 is movably disposed within the first recess 110. The first recess 110 forms a separate accommodating cavity. The second mounting seat 200 has a second wall 220 on the side facing the first wall 120. The second wall 220 moves toward or away from the first wall 120. Under the action of the elastic element 300, the accommodating cavity can extend between the first wall 120 and the second wall 220, thereby adapting to the front-to-back dimensions of the electronic device 500.

[0048] As shown in Figures 3 and 12 , the first wall 120 of the two aforementioned embodiments is provided with a curved portion 130. The curved portion 130 is configured to center the electronic device 500 within the first recess 110 in a direction perpendicular to the direction of movement of the second mounting base 200. It is understood that the curved portion 130 can guide the electronic device 500 to the center in the left-right direction as shown in Figures 3 and 12 . The curved portion 130 can be arranged to be bilaterally symmetrical relative to the centerline L1 of the first wall 120. The centerline L1 of the first wall 120 can also be understood as the centerline of the accommodating cavity in the left-right direction. Specifically, the curved portion 130 can be a continuous curved segment that is bilaterally symmetrical relative to the centerline L1 of the first wall 120. Alternatively, the curved portion 130 can be composed of at least two connected or spaced curved segments, each of which is bilaterally symmetrical relative to the centerline L1 of the first wall 120.

[0049] The embodiment of the present application is provided with a positioning mechanism with an arc-shaped portion 130. When the first wall 120 and the second wall 220 approach each other in the front-to-back direction under the action of elastic force and clamp the electronic device 500, the second wall 220 pushes the electronic device 500 into contact with the arc-shaped portion 130 and is centrally arranged in the accommodating cavity in the left-right direction under the guidance of the arc-shaped portion 130, thereby positioning the electronic device 500 in the positioning mechanism. Compared with the traditional technology that adopts two directions for clamping and positioning, the positioning mechanism of this embodiment only needs to adopt a single direction (front-to-back direction or left-to-right direction) to clamp and position the electronic device 500, so as to achieve fast and accurate positioning of the electronic device 500. It has a simpler structure and is more convenient to operate. It can also be applied to the positioning of electronic devices 500 of different sizes and shapes.

[0050] It is understandable that, as another implementation, the arc portion 130 of the above embodiment can also be set on the second wall 220, which can also enable the electronic device 500 to be centered in the accommodating cavity along the left and right directions, thereby achieving accurate positioning of the electronic device 500.

[0051] It can be understood that, as another embodiment, the first wall 120 and the second wall 220 are both provided with an arc-shaped portion 130, and the arc-shaped portion 130 of the first wall 120 and the arc-shaped portion 130 of the second wall 220 are both configured to be symmetrical with respect to the center line L1 of the first wall 120. The specific structure of the arc-shaped portion 130 of the first wall 120 can be the same as or different from the specific structure of the arc-shaped portion 130 of the second wall 220, as long as the electronic device 500 can be centered in the left and right directions.

[0052] As shown in Figure 3, it can be understood that the curved portion 130 comprises a continuous first curved surface 131 that spans the left and right sides of the first wall 120. The first curved surface 131 is bilaterally symmetrical, meaning that the left and right portions of the first curved surface 131 are symmetrical relative to the centerline L1 of the first wall 120. The portion of the first curved surface 131 to the left of the centerline L1 of the first wall 120 aligns with the left front corner of the electronic device 500, while the portion of the first curved surface 131 to the right of the centerline L1 of the first wall 120 aligns with the right front corner of the electronic device 500. Therefore, the curved portion 130, with this structure, guides the left and right front corners of the electronic device 500, respectively, centering the electronic device 500 toward the center of the accommodating cavity. This smoother and more stable guidance of the electronic device 500 by the curved portion 130 also facilitates demolding, resulting in a high yield and low production costs.

[0053] As shown in Figure 4, the arcuate portion 130 of another embodiment of the present application includes two sections of second arcuate surfaces 132, and the two sections of second arcuate surfaces 132 are connected. The two sections of the second arcuate surfaces 132 are symmetrically arranged on the left and right sides of the center line L1 of the first wall surface 120. The second arcuate surface 132 located on the left side of the first wall surface 120 and the second arcuate surface 132 located on the right side of the first wall surface 120 are symmetrically arranged relative to the center line L1 of the first wall surface 120. Therefore, one section of the second arcuate surface 132 guides the left front corner of the electronic device 500, and the other section of the second arcuate surface 132 guides the right front corner of the electronic device 500, so that the electronic device 500 is centered in the accommodating cavity, and the positioning mechanism accurately positions the electronic device 500.

[0054] As shown in Figure 5, the arcuate portion 130 of another embodiment of the present application includes two spaced-apart third arcuate surfaces 133, and the two third arcuate surfaces 133 are connected by a connecting surface 134. The two third arcuate surfaces 133 are symmetrically arranged on the left and right sides of the center line L1 of the first wall surface 120. The connecting surface 134 can be a plane or an arcuate surface, which is not specifically limited here; the left and right ends of the connecting surface 134 are respectively connected to one end of the third arcuate surface 133. The working principle of the third arcuate surface 133 is basically the same as that of the second arcuate surface 132, and can be understood by referring to the embodiment of the second arcuate surface 132 mentioned above. In order to avoid repetition, it will not be described here.

[0055] 3 , 6 , 11 , and 12 , the positioning mechanism of the embodiment of the present application comprises the first wall surface 120 provided with the curved portion 130, and the second wall surface 220 being a plane. It is understood that by providing the second wall surface 220 as a plane, the contact area between the second wall surface 220 and the electronic device 500 is increased. The second wall surface 220 can contact the entire rear end wall of the electronic device 500 and push the front end wall of the electronic device 500 to mate with the curved portion 130, thereby improving the stability of the electronic device 500 during the entire centering process. Furthermore, when the electronic device 500 is guided by the curved portion 130 and slidably adjusted in the left and right directions, it is more stable and less likely to deflect, thereby increasing the success rate of the electronic device 500's one-time positioning and enhancing the user experience.

[0056] 6 and 11 , it can be understood that the first mounting base 100 is provided with first positioning members 140 located on both sides of the first groove 110 in a direction perpendicular to the movement direction of the second mounting base 200, and the second mounting base 200 is provided with two second positioning members 240, which respectively slidably cooperate with the two first positioning members 140. Therefore, the cooperation structure of the first positioning members 140 and the second positioning members 240 improves the sliding stability of the first mounting base 100 and the second mounting base 200, thereby improving the guiding and positioning effect of the first wall surface 120 and the second wall surface 220 on the electronic device 500, and improving the positioning accuracy of the positioning mechanism.

[0057] 6 and 7 , the two first positioning members 140 of one embodiment of the present application are each provided with a first guide block 141. The first guide block 141 is formed by an upward protrusion from the bottom wall of the first mounting base 100. In one embodiment, the first guide block 141 can be located at an end of the first positioning member 140 away from the first wall 120. In another embodiment, the first guide block 141 can also be located in the middle of the first positioning member 140.

[0058] As shown in Figures 8 and 9, it can be understood that the second mounting base 200 is provided with two second positioning members 240 in the left-right direction. The two second positioning members 240 extend in the front-to-back direction, and the second groove 210 is located between the two second positioning members 240. Each second positioning member 240 is provided with a third guide groove 241, with the notch of the third guide groove 241 facing downward. The two first guide blocks 141 are respectively slidably disposed within the corresponding third guide groove 241. The sliding fit structure of the first guide blocks 141 and the third guide groove 241 can constrain the left-right freedom of the first mounting base 100 and the second mounting base 200, improving the sliding stability of the first mounting base 100 and the second mounting base 200. This further improves the guiding and positioning effect of the first wall 120 and the second wall 220 on the electronic device 500, and enhances the positioning accuracy of the positioning mechanism. Furthermore, the assembly of the first mounting base 100 and the second mounting base 200 is more convenient and quick, improving assembly efficiency.

[0059] 6 and 8 , it can be understood that end walls 242 are provided at both ends of the third guide slot 241 in the front-to-back direction, and the two end walls 242 are provided at both ends of the second positioning member 240. The two end walls 242 respectively restrict the first guide block 141 from moving forward and backward out of the third guide slot 241. Therefore, the end walls 242 can limit the relative position of the first mounting seat 100 and the second mounting seat 200, thereby preventing the first mounting seat 100 and the second mounting seat 200 from separating during use of the positioning mechanism, thereby improving the stability of the positioning mechanism and also enhancing the connection stability between the first mounting seat 100 and the second mounting seat 200.

[0060] 7 and 8 , it can be understood that the first bottom wall 150 of the first groove 110 is provided with a fourth guide groove 151, and the second bottom wall 250 of the second groove 210 is provided with a first protrusion 251 protruding toward one side of the first bottom wall 150. The first protrusion 251 slides with the fourth guide groove 151, thereby constraining the sliding of the first bottom wall 150 and the second bottom wall 250, further improving the stability of the first mounting seat 100 and the second mounting seat 200 when sliding relative to each other.

[0061] 6, 7, and 8, it can be understood that a third groove 252 is formed on the side of the first protrusion 251 facing away from the first bottom wall 150. The third groove 252 is formed by the second bottom wall 250 protruding toward the first bottom wall 150. The elastic element 300 is disposed in the third groove 252, so that the elastic element 300 does not interfere with the electronic device 500 during deformation or movement, making the layout of the elastic element 300 more reasonable and improving space utilization.

[0062] A positioning mechanism of an embodiment of the present application is provided with a first hook 152 on the first bottom wall 150, and a second hook 253 on the second bottom wall 250. The elastic element 300 is a rubber band, and the two ends 310 of the rubber band are bent and deformed and hung on the first hook 152 and the second hook 253 respectively. The middle part of the rubber band is embedded in the third groove 252. The depth of the third groove 252 can be set to be greater than the thickness of the rubber band, so that the rubber band will not interfere with the electronic device 500 when stretched or retracted.

[0063] The elastic element 300 of the positioning mechanism of another embodiment of the present application is a rubber band, and the two ends 310 of the rubber band are respectively hung on the first hook 152 and the second hook 253, and the middle part of the rubber band is located below the first bottom wall 150 and the second bottom wall 250, so that the rubber band will not interfere with the electronic device 500 when stretched or retracted, making the layout of the elastic element 300 more reasonable and the space utilization rate higher.

[0064] In another embodiment of the present application, a positioning mechanism is provided in which the first bottom wall 150 of the first groove 110 is provided with a second protrusion. A fifth guide groove is formed on the side of the second bottom wall 250 of the second groove 210 facing the first bottom wall 150, and the fifth guide groove slidably engages with the second protrusion. A fourth groove is formed on the side of the second protrusion facing away from the second bottom wall 250. The first bottom wall 150 is provided with a first hook 152, and the second bottom wall 250 is provided with a second hook 253. The elastic element 300 is a rubber band, which is positioned within the fourth groove and has its ends hooked on the first hook 152 and the second hook 253, respectively. This embodiment can also improve the sliding stability of the first mounting base 100 and the second mounting base 200.

[0065] As shown in Figures 11 and 12, another embodiment of the present application shows a first guide groove 142 on the first positioning member 140. The first guide groove 142 is located on the side of the first positioning member 140 facing the first groove 110. Specifically, the first guide groove 142 is located on the right side of the first positioning member 140 on the left side, and the first guide groove 142 is located on the left side of the first positioning member 140 on the right side. The two first guide grooves 142 extend along the movement direction of the second mounting base 200. Second guide blocks 244 are respectively provided on the left and right sides of the second positioning member 240, and the two second guide blocks 244 are respectively inserted into the corresponding first guide grooves 142. The second positioning member 240, through the cooperation of the second guide blocks 244 and the first guide grooves 142, can improve the stability of the second mounting base 200 when sliding relative to the first mounting base 100, thereby improving the guiding and positioning effect of the first wall 120 and the second wall 220 on the electronic device 500, thereby improving the positioning accuracy of the positioning mechanism. Moreover, the assembly of the first mounting seat 100 and the second mounting seat 200 is more convenient and quick, thereby improving the assembly efficiency.

[0066] In order to enable the second mounting seat 200 to slide stably in the direction close to or away from the first mounting seat 100, the elastic element 300 is a spring, one end of which is fixedly connected to the first positioning member 140, and the other end is fixedly connected to the second guide block 244. The spring can be built into the first positioning member 140, or it can be externally placed on the first positioning member 140 or the first bottom wall 150 of the first groove 110, which is not further specified here.

[0067] As shown in Figure 1 , the film application device of the present embodiment includes the positioning mechanism of the above embodiment and a film assembly 400. The film assembly 400 is detachably connected to the positioning mechanism. Therefore, when applying a film to an electronic device 500, the user can first place the electronic device 500 into the positioning mechanism for positioning, and then install the film assembly 400, making the operation more convenient.

[0068] Since the film sticking device adopts all the technical solutions of the positioning mechanism of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be described in detail here.

[0069] 1 and 2 , it can be understood that a first edge 160 is provided on a side of the first mounting seat 100 close to the first wall 120 , and the first edge 160 is provided with a first positioning boss 161 , which is formed by protruding upward from the upper surface of the first edge 160 .

[0070] 13 and 14 , the diaphragm assembly 400 includes a positioning film 410, a protective film 420, a release film 430, and a traction film 440. The protective film 420 is a protective component that is ultimately attached to the screen of the electronic device 500. The protective film 420 may be made of plastic or glass. Depending on its function, the protective film 420 may be an explosion-proof film, a privacy film, a writing film, or the like. One side of the protective film 420 is coated with glue. The side coated with glue is the side of the protective film 420 facing the electronic device 500, and is also the side facing the positioning mechanism. The release film 430 is connected to the side of the protective film 420 coated with glue, and the release film 430 covers the entire protective film 420. The positioning film 410 is connected to the side of the protective film 420 that is not coated with glue, that is, the side of the protective film 420 that is away from the positioning mechanism.

[0071] The positioning film 410 is provided with a first positioning hole 411, which is a through hole. After the first positioning hole 411 engages with the first positioning boss 161, the diaphragm assembly 400 is fixedly connected to the positioning mechanism. The matching structure of the first positioning hole 411 and the first positioning boss 161 can limit the translational movement of the protective film 420 relative to the positioning mechanism, preventing the diaphragm assembly 400 from swinging during the film application operation, which would result in a decrease in alignment accuracy. This limits the translational movement of the protective film 420 relative to the positioning mechanism, allowing the protective film 420 to be stably positioned with the positioning mechanism, thereby improving the alignment accuracy of the protective film 420 and the screen of the electronic device 500. It is understandable that the first positioning hole 411 and the first positioning boss 161 can be fixed by snapping or by interference fit, thereby limiting the displacement and rotation of the positioning film 410 relative to the first mounting seat 100.

[0072] It is understandable that the positioning film 410 can be set to cover the entire protective film 420, or it can be set to cover part of the protective film 420, as long as the positioning film 410 can be tightly attached to the protective film 420 to avoid the positioning film 410 from separating from the protective film 420 during the film-sticking operation.

[0073] It is understandable that the traction film 440 is used to guide the release film 430 to tear off the protective film 420, thereby reducing the dust or debris that falls between the screen and the film during the attachment process of the film and the screen of the electronic device 500, thereby improving the quality of the film. When the electronic device 500 is filmed, the traction film 440 is also used as a dust removal film. Specifically, the traction film 440 is in contact with the screen of the electronic device 500. When the traction film 440 is pulled by the user, the traction film 440 contacts the screen and removes the dust on the screen. After the dust is removed, the release film 430 is separated from the protective film 420 to prevent the dust from falling onto the surface of the screen again. When the protective film 420 is attached to the screen, no bubbles are generated due to the dust on the screen surface, thereby improving the quality of the film.

[0074] To facilitate the removal of the release film 430 from the protective film 420, the end of the traction film 440 near the first positioning hole 411 is connected to the end of the release film 430 near the first positioning hole 411, while the end of the traction film 440 away from the first positioning hole 411 extends beyond the protective film 420. The traction film 440 extends in a front-to-back direction. The portion of the traction film 440 that extends beyond the protective film 420 facilitates manual pulling. During the pulling process, the traction film 440 pulls the release film 430 away from the protective film 420, making the operation more convenient. As the release film 430 is pulled away from the protective film 420, the protective film 420 contacts the screen of the electronic device 500, preventing the intrusion of dust and debris. Furthermore, due to the stable positioning of the positioning film 410 and the first mounting base 100, the traction film 440 is less likely to cause misalignment between the protective film 420 and the screen of the electronic device 500 during the pulling process, thereby improving the accuracy of film application to the electronic device 500. Therefore, the entire film-sticking operation of the film-sticking device of the embodiment of the present application is simple and convenient.

[0075] 1 and 2 , a second edge is provided on the side of the second mounting seat 200 close to the second wall surface 220. The second edge is arranged opposite to the first edge 160, and the traction film 440 abuts against the second edge, so that the diaphragm assembly 400 can be better supported on the upper surface of the positioning mechanism, which is beneficial for the protective film 420 to be tilted upward from the front end to the rear end during the film application process, so that the protective film 420 and the screen of the electronic device 500 can be better attached.

[0076] In addition, one end of the traction film 440 away from the first positioning hole 411 extends beyond the second edge. The portion of the traction film 440 extending beyond the second edge can be easily pulled by the user, making the operation more convenient.

[0077] It is understood that the cross-sectional shape of the first positioning hole 411 is the same as that of the first positioning boss 161. For example, the cross-sectional shape of the first positioning hole 411 is a square, and the cross-sectional shape of the first positioning boss 161 is also a square. Therefore, when the first positioning hole 411 and the first positioning boss 161 are mated, there is no gap between them that could cause displacement of the positioning film 410 and the positioning mechanism, thereby further improving the positioning accuracy of the protective film 420 and the screen of the electronic device 500.

[0078] As shown in Figures 2 and 3, it can be understood that the first positioning boss 161 is elongated, with its length perpendicular to the extension direction of the traction film 440, that is, the first positioning boss 161 extends in the left-right direction in Figure 3. When the traction film 440 is pulled by the user, the force acting on the positioning film 410 and the protective film 420 is from front to back in Figure 3. Therefore, increasing the contact area of ​​the first positioning boss 161 in the front-to-back direction can ensure that the positioning film 410 is not easily separated from the positioning mechanism during the pulling of the traction film 440, thereby improving the reliability of the film application operation.

[0079] As another embodiment, the cross section of the first positioning boss 161 may also be set to be an ellipse or a polygon, or may be set to be other shapes that can limit the translation or deflection of the positioning film 410 .

[0080] It is understandable that in another embodiment of the film-sticking device of the present application, the first positioning boss 161 includes at least two positioning units, for example, two, three or more are provided. The positioning unit can also be formed by an upward protrusion of the upper surface of the first edge 160. Two adjacent positioning units among the multiple positioning units can be spaced apart or interconnected. The shapes of the multiple positioning units can be the same or different, and the cross-section of one positioning unit is circular, elliptical or polygonal. Correspondingly, there can be multiple first positioning holes 411, and each first positioning hole 411 is respectively engaged with the corresponding positioning unit; there can also be only one first positioning hole 411, and it is engaged with the entire first positioning boss 161 including multiple positioning units.

[0081] 1 , 13 and 14 , it can be understood that in order to improve the connection stability between the positioning film 410 and the protective film 420, the positioning film 410 includes an attachment portion 412 and a first positioning portion 413. The attachment portion 412 covers most of the structure of the protective film 420, the first positioning portion 413 is connected to the attachment portion 412 and protrudes from the protective film 420, and the first positioning hole 411 is located in the first positioning portion 413. The first positioning portion 413 is configured as a handle that facilitates the user to tear off the positioning film 410 from the surface of the protective film 420. After the film is applied, the user tears the first positioning portion 413 off the first positioning boss 161, and the user can pull the attachment portion 412 and the protective film 420 through the first positioning portion 413 to smoothly separate them, thereby preventing the protective film 420 attached to the screen of the electronic device 500 from being pulled away by the positioning film 410.

[0082] It can be understood that as it approaches the attachment portion 412, the size of the first positioning portion 413 in the left and right directions gradually increases, and the contact surface between the first positioning portion 413 and the attachment portion 412 is larger, so that the first positioning portion 413 can more conveniently pull the attachment portion 412 to separate from the protective film 420.

[0083] The positioning film 410 includes a second positioning portion 414 and a third positioning portion 415. For example, the second positioning portion 414 is located at the left end of the attachment portion 412, and the third positioning portion 415 is located at the right end of the attachment portion 412. The second positioning portion 414 abuts against the second positioning member 240 on the left side, while the third positioning portion 415 abuts against the second positioning member 240 on the right side. This allows the diaphragm assembly 400 to be better supported on the upper surface of the positioning mechanism, improving the stability of the diaphragm assembly 400 during installation.

[0084] As shown in Figure 1 , to improve the installation stability of the diaphragm assembly 400, the two second positioning members 240 are each provided with a second positioning boss 243. The diaphragm assembly 400 is supported on the upper surfaces of the two second positioning members 240 and positioned between the two second positioning bosses 243, thereby constraining the diaphragm assembly 400's freedom in the left-right direction, thereby improving the positioning accuracy of the protective film 420 and the screen of the electronic device 500. This also improves the convenience of the user in installing the diaphragm assembly 400 on the positioning mechanism.

[0085] 15 , the film applying method of the film applying device according to the embodiment of the present application is to apply a film to the screen of the electronic device 500 using the film applying device according to the embodiment of the present application. The film applying method according to the embodiment of the present application includes the following steps:

[0086] S1501: Provide a film-sticking device as described in the above embodiments.

[0087] S1502: Provide an electronic device 500.

[0088] S1503: Move the second mounting base 200 away from the first wall 120, and place the electronic device 500 in the first groove 110, so that the electronic device 500 is centered under the resetting action of the first wall 120 and the second wall 220. Through these steps, the screen of the electronic device 500 and the positioning mechanism are positioned.

[0089] S1504: Engage the positioning film 410 with the first positioning boss 161 through the first positioning hole 411, so that the film assembly 400 is installed on the positioning mechanism. Through the above steps, the film assembly 400 can be positioned with the positioning mechanism, thereby achieving accurate alignment between the protective film 420 and the screen of the electronic device 500, improving the quality of the film application.

[0090] S1505: Pull out the traction film 440 until both the traction film 440 and the release film 430 are detached from the film application device. Through the above steps, the traction film 440 contacts the screen of the electronic device 500 and removes dust from the screen. After dust removal, the release film 430 is separated from the protective film 420 to prevent dust from falling back onto the screen surface.

[0091] S1506: A force is applied to the positioning film 410 in the direction of the pull-out of the traction film 440, toward the screen of the electronic device 500, so that the protective film 420 is adhered to the screen. Through these steps, the protective film 420 is first adhered along the width of the screen, forming an air vent boundary extending along the width of the screen. The protective film 420 then gradually tilts along the length of the screen through the air vent boundary to vent air while adhering to the screen. This allows for more orderly and smooth air venting, reduces the generation of bubbles, and improves the quality of the film application.

[0092] S1507: Detaching the positioning film 410 from the positioning mechanism. By doing this, the user can remove the positioning film 410 from the positioning mechanism without removing the protective film 420 from the screen. Once the positioning film 410 is removed, the finished electronic device 500 is exposed in the first groove 110.

[0093] S1508: Take the electronic device 500 out of the first groove 110. It is understandable that the user can facilitate taking the electronic device 500 out of the first groove 110 by spreading the first mounting seat 100 and the second mounting seat 200 apart.

[0094] The film pasting method of the embodiment of the present application is simple and convenient to operate, and has high film pasting efficiency; it also has high film pasting precision and good quality, and can be applied to film pasting operations on electronic devices 500 of different sizes and shapes, and has strong versatility.

[0095] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
