Description

Technical Field

[0001] This invention belongs to the field of electronic product accessories technology, and in particular relates to a film application device. Background Technology

[0002] With the rapid development of society, electronic devices such as mobile phones, tablets, and smartwatches are widely used. To extend the lifespan of these devices, many people use screen protectors. In reality, screen protectors are mostly applied manually, and the efficiency depends heavily on the operator's experience. If the operator is not skilled, problems such as difficulty in positioning the protector, dust residue on the screen, and air bubbles may occur, affecting both the application effect and efficiency.

[0003] Related technologies have also led to the development of screen protector applicators. These applicators typically include a base and a cover movably connected to the base. The base is used to fix the electronic device, and the cover has positioning protrusions for engaging with the screen protector assembly. The screen protector assembly includes a protective film for bonding with the electronic device, a first release film connected to the outside of the protective film, and a second release film connected to the inside of the protective film (i.e., the adhesive side for bonding with the screen). The first release film has a limiting part that engages with the positioning protrusions, and the second release film has a pull part for user operation. After the screen protector assembly, cover, and base are fixed in place, the second release film can be pulled off by the pull part, allowing the protective film to automatically adhere to the screen. This design can improve problems such as positioning difficulties, residual dust, and residual air bubbles to some extent. However, most of these applicators are only suitable for applying tempered glass screen protectors. If applying soft screen protectors, problems such as inaccurate positioning and air bubbles are likely to occur. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a film application device, which aims to solve the problems of air bubbles and inaccurate positioning of film applicators for applying soft films in related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows: a film application device includes a base, a film clamping assembly, and a film pressing assembly. The base is provided with accommodating grooves adapted to the shape of the electronic device and limiting grooves adapted to the shape of the film clamping assembly. Slide rails are formed on opposite sides of the base. The film clamping assembly is detachably connected to the base and is used to clamp the end of the soft film and to engage with the limiting grooves. The film pressing assembly includes a mounting base, a pressing member connected to the mounting base, a limiting assembly, and a limiting edge for sliding engagement with the slide rails. The limiting assembly stabilizes the position of the soft film when the tail end of the soft film bends around the outer periphery of the mounting base and ensures that the soft film is tightly adhered to the pressing member. The pressing member presses the protective film in the soft film onto the screen of the electronic device during the relative sliding process of the mounting base and the base.

[0006] Furthermore, a guide slope is formed at the end of the slide rail near the limiting groove.

[0007] Furthermore, the mounting base includes a base body and upright plates connected to both sides of the base body, with limiting edges respectively connected to the bottom ends of the upright plates, and the limiting edges located on the side of the two upright plates that are close to each other.

[0008] Furthermore, the pressing component is a pressure plate fixed on the base, and / or, the pressing component is a first roller connected between the two upright plates.

[0009] Furthermore, the limiting component is installed on the forward side or above the seat.

[0010] Furthermore, the limiting component includes a rotating shaft, a second roller, and a double torsion spring. The rotating shaft is connected between the two upright plates, and the second roller is sleeved on the outer periphery of the rotating shaft. The double torsion spring includes a first abutting part and spring parts connected to both ends of the first abutting part. The two spring parts are respectively sleeved on both ends of the rotating shaft and fixedly connected to the second roller. The first abutting part is located outside the second roller and is used to cooperate with the second roller to clamp the soft film during the film application process.

[0011] Furthermore, the limiting buckle includes a second abutting part and a fastening part connected to the second abutting part, and the top of the seat body is provided with a fastening groove adapted to the fastening part; the second abutting part is used to form abutment with the soft film and make the soft film adhere to the pressing part when the fastening part is fastened into the fastening groove.

[0012] Furthermore, the membrane clamping assembly is provided with a first magnetic attractor and the bottom side of the base is provided with a second magnetic attractor. The second magnetic attractor is used to attract the first magnetic attractor to achieve initial positioning between the base and the membrane clamping assembly.

[0013] Furthermore, the membrane clamping assembly includes a first fixing member and a second fixing member, and a first magnetic member is embedded in the first fixing member or the second fixing member; the positioning part is clamped between the first fixing member and the second fixing member by a snap-fit ​​connection and / or magnetic attraction.

[0014] Furthermore, a notch for connecting the receiving groove is formed above the base.

[0015] Compared with the prior art, the film application device of this invention has the following advantages: the film clamping component and the film pressing component are detachably connected to the base. The film clamping component can clamp and stabilize the position of the soft film, thereby achieving precise positioning of the soft film and the electronic device in the base. Moreover, the limiting component can stabilize the position of the soft film when the user folds and rolls it up along the outer periphery of the mounting base, and make the soft film adhere tightly to the pressing component. This can effectively prevent the part of the protective film that is being applied to the screen from deforming and generating air bubbles, which is beneficial to improving the film application efficiency.

[0028] Example:

[0029] like Figure 1-5 As shown, in this embodiment, the film application device includes a film application assembly 1 and a base 2. The film pressing assembly 11 includes a film pressing assembly 11 and a film clamping assembly 12. The base 2 is provided with a receiving groove 21 adapted to the shape of the electronic device 4 and a limiting groove adapted to the shape of the film clamping assembly 12. Slide rails 24 are also formed on opposite sides of the base 2. The film clamping assembly 12 is detachably connected to the base 2 and is used to clamp the end of the soft film 3 and to engage with the limiting groove. The film pressing assembly 11 includes a mounting base 111, a pressing member 112 connected to the mounting base 111 and a limiting assembly 113, and a limiting edge 114 for sliding engagement with the slide rail 24. The limiting assembly 113 is used to stabilize the position of the soft film 3 when the tail end of the soft film 3 bends around the outer periphery of the mounting base 111 and to make the soft film 3 adhere tightly to the pressing member 112. The pressing member 112 is used to press the protective film 32 in the soft film 3 onto the screen of the electronic device 4 during the relative sliding process of the mounting base 111 and the base 2.

[0030] Specifically, in this embodiment, the electronic device 4 can be a mobile phone, tablet, or other electronic product that requires the application of a soft film 3. The receiving groove 21 is used to place the electronic device 4. When the electronic device 4 is placed in the receiving groove 21, each peripheral side of the electronic device 4 abuts against the groove wall of the receiving groove 21, thereby achieving positioning of the electronic device 4. The film clamping assembly 12 and the film pressing assembly 11 are detachably connected to the base 2. The film clamping assembly 12 can clamp and stabilize the position of the soft film 3, thereby achieving precise positioning of the soft film 3 and the electronic device 4 in the base 2; and the film pressing assembly 11 can slide relative to the base 2, thereby pressing the protective film 32 onto the screen of the electronic device 4 during the sliding process. It can be seen that the film application device of this application has a simple structure and good positioning effect. Furthermore, the limiting assembly 113 of this embodiment can stabilize the position of the soft film 3 when the user folds and rolls it up along the outer periphery of the mounting base 111, and ensure that the soft film 3 is tightly adhered to the pressing component 112. This effectively prevents deformation of the part of the protective film 32 that is being applied to the screen, thus avoiding air bubbles and improving the film application efficiency.

[0031] In this embodiment, as Figure 5 As shown, the flexible film 3 may include a protective film 32, a first release film 31 and a second release film 33 respectively connected to both sides of the protective film 32. One end of the first release film 31 is provided with a positioning part 311 for clamping by the film clamping assembly 12, and the positioning part 311 is not connected to the protective film 32. The second release film 33 is connected to the bonding side of the protective film 32, and the second release film 33 is not connected to the positioning part 311. Before applying the film, the positioning part 311 can be clamped securely by the film clamping assembly 12, and the film clamping assembly 12 can be fixed to the base 2, thereby achieving positioning. The pressing member 112 in the film pressing assembly 11 can slide relative to the base 2 and press the protective film 32 onto the screen of the electronic device 4 during the sliding process.

[0032] When applying the film, a small portion of the second release film 33 can be torn away from the protective film 32 from the side closest to the film clamping assembly 12, so that the inner side of the torn portion of the second release film 33 (the side that adheres to the protective film 32) abuts against the screen of the electronic device 4. Then, pushing the film pressing assembly 11 will automatically separate the second release film 33 from the protective film 32, while the protective film 32 will gradually be pressed onto the screen. After the protective film 32 is completely adhered to the screen, the film pressing assembly 11 can be removed, and the first release film 31 can be torn off. The whole process is simple and quick, which helps to improve the efficiency of soft film application.

[0033] It is understood that in this embodiment, the guide structure may only guide the film-pressing assembly 11. When applying the film, the user can simultaneously apply pressure in the height direction and thrust in the horizontal direction to the film-pressing assembly 11, so that the film-pressing assembly 11 can press the protective film 32 onto the screen during the sliding process. Of course, in some preferred embodiments, the guide structure not only guides the film-pressing assembly 11, but also limits its position. That is, the guide structure can limit the position of the film-pressing assembly 11 in the height direction. When applying the film, the user only needs to apply thrust in the horizontal direction to the film-pressing assembly 11. For example, slide rails 24 can be provided on opposite sides of the base 2, and a limiting edge 114 corresponding to the slide rail 24 can be provided on the bottom edge of the pressing assembly, so that the lower side of the slide rail 24 abuts against the upper side of the limiting edge 114. In this way, the pressing assembly can slide along the slide rail 24 and complete the film application even when only subjected to horizontal thrust. Using this method to manufacture the film pressing assembly 11 can ensure that the film pressing assembly 11 always provides a stable pressing force to the soft film 3 during the sliding process, resulting in a good film application effect.

[0034] In this embodiment, the film clamping assembly 12 includes a detachably connected first fixing member 121 and a second fixing member 122. The first fixing member 121 and the second fixing member 122 cooperate to clamp the end of the soft film 3. A first magnetic suction member is embedded in the first fixing member 121 or the second fixing member 122. The film pressing assembly 11 is used to press the protective film 32 in the soft film 3 onto the screen of the electronic device 4 under the action of external force. The film pressing assembly 11 has a second magnetic suction member, which is used to attract each other with the first magnetic suction member to achieve initial positioning between the film pressing assembly 11 and the film clamping assembly 12. That is, the first fixing member 121 and the second fixing member 122 can be connected by snap-fit ​​and / or magnetic attraction, thereby achieving a stable clamping of the positioning part 311. Through the interaction of the first magnetic suction member and the second magnetic suction member, the initial positioning of the film pressing assembly 11 and the film clamping assembly 12 can be achieved, and the positioning effect is good.

[0035] In this embodiment, the mounting base 111 includes a base body 1111 with upright plates 1112 connected to both sides of the base body 1111, and a second magnetic chuck embedded in the bottom side of the base body 1111. Limiting edges 114 are respectively connected to the bottom ends of the two upright plates 1112, with the limiting edges 114 located on the sides of the two upright plates 1112 that are close to each other. Slide rails 24 are also formed on opposite sides of the base 2, and the slide rails 24 are used to slide and engage with the corresponding limiting edges 114. The position of the second magnetic chuck is different from that of the pressing member 112; in the direction of the sliding movement of the film pressing assembly 11, the second magnetic chuck is located behind the pressing member 112. During the relative sliding process between the slide rails 24 and the limiting edges 114, the pressing member 112 can press the protective film 32 in the soft film 3 onto the screen of the electronic device 4. The base body 1111, upright plates 1112, and limiting edges 114 can be obtained by integral injection molding, resulting in good structural stability and low production cost.

[0036] In one embodiment, a first magnetic chuck is embedded in a first fixing member 121, and a third magnetic chuck is also provided in a second fixing member 122. When the film pressing assembly 11, the film clamping assembly 12, and the soft film 3 are aligned, the end of the first magnetic chuck away from the second magnetic chuck attracts the third magnetic chuck, causing the first fixing member 121 and the second fixing member 122 to move closer together and clamp the soft film 3. That is, after the positioning part 311 of the soft film 3 is placed between the first fixing member 121 and the second fixing member 122, the magnetic attraction between the first magnetic chuck and the third magnetic chuck can attract the first fixing member 121 and the second fixing member 122 closer together, thereby clamping the soft film 3, which is convenient to use.

[0037] In this embodiment, the first fixing member 121 is provided with a clearance hole 1211, and the second fixing member 122 has a limiting part 1221 adapted to the clearance hole 1211. The limiting part 1221 is used to pass through the positioning hole 312 and the clearance hole 1211 at the end of the soft membrane 3 in sequence, thereby limiting the soft membrane 3 and the first fixing member 121. That is, the positioning part 311 is provided with a positioning hole 312 for the limiting part 1221 to pass through, and the shapes of the positioning hole 312 and the limiting part 1221 are perfectly matched. In use, the cooperation between the limiting part 1221 and the clearance hole 1211 can limit the position of the positioning part 311 in the horizontal direction, thereby achieving precise positioning of the soft membrane 3, and further enhancing the connection stability between the first fixing member 121 and the second fixing member 122. Of course, in some other embodiments, the clearance hole 1211 may be provided on the second fixing member 122, and the limiting part 1221 may be provided on the first fixing member 121. There are no restrictions here.

[0038] In another embodiment, the first magnetic chuck is embedded in the first fixing member 121. When the film pressing assembly 11, the film clamping assembly 12, and the soft film 3 are aligned, the soft film 3 and the second fixing member 122 are both located between the first magnetic chuck and the second magnetic chuck. That is, during initial positioning, the second fixing member 122 is located between the soft film 3 and the film pressing assembly 11. Through the magnetic attraction between the first magnetic chuck and the second magnetic chuck, the first fixing member 121 and the film pressing assembly 11 can firmly clamp the soft film 3 and the second fixing member 122. At the same time, the cooperation between the clearance hole 1211, the positioning hole 312, and the limiting part 1221 can further improve the fixing stability of the positioning part 311 in the film clamping assembly 12.

[0039] In this embodiment, one or more spaced clearance holes 1211 can be provided, the number of positions of the limiting parts 1221 corresponds to the clearance holes 1211, and the number of positions of the positioning holes 312 also corresponds to the clearance holes 1211. Preferably, two clearance holes 1211 can be provided, which has a good positioning effect and a simple structure and beautiful appearance. Further, in this embodiment, the second fixing member 122 is also provided with limiting holes 1222 for fixing in cooperation with the positioning post 22 on the base 2. That is, the positioning post 22 is provided on the top of the base 2; the membrane assembly 12 has limiting holes 1222 adapted to the positioning post 22; one or more limiting holes 1222 can be provided, and the number of positioning posts 22 is equal to the number of limiting holes 1222. When the initially positioned film-applying assembly 1 is installed into the base 2, that is, when the film-clamping assembly 12 holding the soft film 3 is installed in place with the base 2, the positioning post 22 can be inserted into the limiting hole 1222 and engage with the limiting hole 1222, thereby fixing the film-clamping assembly 12 to the base 2. Then, the film-pressing assembly 11 can be pushed to separate the film-clamping assembly 12, and then the subsequent film-applying operation can be performed. Furthermore, in this embodiment, the limiting hole 1222 penetrates the limiting part 1221; the height of the positioning post 22 can be greater than the thickness of the second fixing member 122, and the height of the positioning post 22 is less than or equal to the sum of the thicknesses of the first fixing member 121, the second fixing member 122, and the positioning part 311, resulting in good positioning effect and a simpler and more aesthetically pleasing appearance for the film-clamping assembly 12.

[0040] Furthermore, in this embodiment, the pressing member 112 is a pressure plate 1121 fixed on the base 1111, and / or, the pressing member 112 is a first roller 1122 connected between the two upright plates 1112.

[0041] Furthermore, in this embodiment, the pressing component 112 can be a pressing plate 1121 disposed at the bottom end of the base 1111. The bottom side of the pressing plate 1121 has a pressing surface adapted to the electronic device 4. During the movement of the mounting base 111, the pressing surface can press the protective film 32 firmly onto the screen, resulting in high film application efficiency. Further, in some embodiments, concave surfaces are formed at both ends of the pressing plate 1121. These concave surfaces are used to press the edges of the protective film 32 onto the curved area of ​​the screen of the electronic device 4. That is, in some specific embodiments, the electronic device 4 can be a curved screen mobile phone. Correspondingly, concave surfaces adapted to the shape of the curved screen mobile phone can be provided on both sides of the pressing surface, thereby allowing the protective film 32 to be accurately and completely applied to each screen area of ​​the curved screen mobile phone.

[0042] In this embodiment, the pressing component 112 can also be a first roller 1122 connected between the two upright plates 1112, with the first roller 1122 located at the bottom of the base 1111. The bottom ends of each upright plate 1112 are used for sliding engagement with the base 2. In this embodiment, the base 1111 and the upright plates 1112 are integrally connected, that is, the base 1111 and the upright plates 1112 can be obtained by integral injection molding, resulting in good structural stability and low production cost. The bottom side of the base 1111 has a clearance space adapted to the shape of the first roller 1122. During the relative sliding process between the mounting base 111 and the base 2, the surface of the first roller 1122 rolls and rubs against the surface of the first release film 31, pressing the protective film 32 onto the screen.

[0043] It is understood that in some embodiments, the film pressing assembly 11 may only have a pressure plate 1121 or only have a first roller 1122, and the film pressing assembly 11 may also have both a pressure plate 1121 and a first roller 1122.

[0044] In one embodiment, a pressure plate 1121 and a first roller 1122 can be provided simultaneously, and the pressure plate 1121 can be located in front of the first roller 1122 in the forward direction. The pressing surface of the pressure plate 1121 can be flush with the lowest point of the roller surface to ensure that the protective film 32 adheres tightly to the screen. Of course, in some specific embodiments, the pressing surface of the pressure plate 1121 can also be slightly higher than the lowest point of the roller surface. In this case, the pressure plate 1121 mainly plays a guiding role and stabilizes the position of the soft film 3, while the first roller 1122 mainly plays a pressing role. This arrangement can also achieve precise adhesion between the protective film 32 and the screen.

[0045] In this embodiment, the film pressing assembly 11 is further provided with a limiting assembly 113. The limiting assembly 113 can stabilize the position of the soft film 3, so that the soft film 3 is tightly attached to the pressing member 112 during the application process, which helps to reduce the possibility of air bubbles. The limiting assembly 113 is connected between the two upright plates 1112, and the limiting assembly 113 is located on the forward side or above the base 1111. That is, during the application process, one end of the soft film 3 is fixed to the end of the base 2 by the film clamping assembly 12, and the other end can wrap around the outside of the mounting base 111 and be limited by the limiting assembly 113, so as to prevent the unapplied part of the soft film 3 from drooping and swinging during the application process, which would affect the application process. At the same time, the limiting assembly 113 can also tighten the soft film 3, that is, to make the soft film 3 appropriately taut and tightly attached to the pressing member 112, effectively avoiding the generation of air bubbles.

[0046] In this embodiment, the limiting component 113 includes a rotating shaft 1131, a second roller 1132, and a double torsion spring 1133. The second roller 1132 is sleeved on the outer periphery of the rotating shaft 1131. The double torsion spring 1133 includes a first abutting portion and spring portions connected to both ends of the first abutting portion. The two spring portions are respectively sleeved on both ends of the rotating shaft 1131 and fixedly connected to the second roller 1132. The first abutting portion is located outside the second roller 1132 and is used to cooperate with the second roller 1132 to clamp the soft film 3 during the film application process. The limiting component composed of the rotating shaft 1131, the second roller 1132, and the double torsion spring 1133 can be installed in the middle of the forward side of the mounting base 111. The fixing of the spring portions makes the first abutting portion have a restoring force toward the second roller 1132, so that when the soft film 3 is not installed, the first abutting portion automatically abuts against the outside of the second roller 1132 under the action of the restoring force. In use, the soft film 3 can pass between the second roller 1132 and the double torsion spring 1133. During the movement of the film application assembly 1, the second roller 1132 and the double torsion spring 1133 can cooperate to clamp the soft film 3.

[0047] In this embodiment, the limiting component 113 further includes a limiting buckle 1134, which includes a second abutment portion 11341 and a fastening portion 11342 connected to the second abutment portion 11341. The top of the seat 1111 is provided with a fastening groove 1113 adapted to the fastening portion 11342. The second abutment portion 11341 is used to form an abutment with the soft membrane 3 and make the soft membrane 3 adhere to the surface of the seat 1111 when the fastening portion 11342 is fastened into the fastening groove 1113. The limiting buckle 1134 can be disposed above the mounting base 111 to further stabilize the position of the soft membrane 3.

[0048] Furthermore, in this embodiment, the limiting buckle 1134 also includes a connecting portion 11343 connected to the second abutting portion 11341. The side of the upright plate 1112 facing the base 1111 is also provided with a mounting groove. The connecting portion 11343 has connecting posts at both ends that are adapted to the mounting groove. The connecting posts are used to rotate with the mounting groove so that the limiting buckle 1134 can move to the first position or the second position. When the limiting buckle 1134 moves to the first position, the fastening portion 11342 and the fastening groove 1113 are fastened and fixed. When the limiting buckle 1134 moves to the second position, the second abutting portion 11341 and the base 1111 are separated from each other.

[0049] Specifically, the limiting buckle 1134 is hinged between the two upright plates 1112. When the user applies force to the limiting buckle 1134 in different directions, the limiting buckle 1134 can flip, that is, the limiting buckle 1134 can move to the first position or the second position under the action of external force. When the limiting buckle 1134 moves to the first position, the fastening part 11342 is just engaged and fixed with the fastening groove 1113. At the same time, the second abutting part 11341 can press against the surface of the seat 1111 to clamp the soft membrane 3, thereby realizing the position restriction of the soft membrane 3. When the limiting buckle 1134 moves to the second position, the second abutting part 11341 separates from the seat 1111, which makes it convenient for the user to insert the soft membrane 3 (making it convenient to put the end of the soft membrane 3 away from the clamping assembly 12 between the limiting buckle 1134 and the seat 1111). Furthermore, in this embodiment, the connecting portion 11343 and the second abutting portion 11341 enclose a clearance opening 1134a for the soft membrane 3 to pass through. The presence of the clearance opening 1134a can restrict the position of the soft membrane 3 to a certain extent and is also more convenient for the user to operate. In this embodiment, an operating portion 11344 can also be provided on the limiting buckle 1134. The operating portion 11344 is connected to the second abutting portion 11341, making it convenient for the user to pry and flip the limiting buckle 1134.

[0050] In this embodiment, a limiting groove adapted to the film clamping assembly 12 is provided at the bottom of the mounting base 111 and / or above the base 2; during initial positioning, the film clamping assembly 12 engages with the limiting groove. Specifically, the limiting groove in this embodiment may include a first limiting groove 1114 and a second limiting groove 23. That is, a first limiting groove 1114 adapted to the shape of the first fixing member 121 is formed on the bottom side of the base body 1111 of the mounting base 111. The first limiting groove 1114 is used to limit the engagement with the first fixing member 121, making the connection between the mounting base 111 and the film clamping assembly 12 more stable during initial positioning. A second limiting groove 23 is provided above the base 2. The shape and size of the second limiting groove 23 are adapted to the second fixing member 122. The positioning post 22 is connected to the bottom of the second limiting groove 23. Through the cooperation between the second fixing member 122 and the second limiting groove 23, the connection stability between the film clamping assembly 12 and the base 2 can be further improved.

[0051] In this embodiment, the length of the slide rail 24 is less than the length of the base 2 in the sliding direction. That is, in use, the film application assembly 1 can first be inserted into the base 2 from above the end of the base 2 (above the second limiting groove 23), and at the same time, the positioning post 22 will be inserted into the limiting hole 1222 and engage with the limiting hole 1222, thereby fixing the film clamping assembly 12 to the base 2; then, the film pressing assembly 11 can be pushed to separate the film pressing assembly 11 from the film clamping assembly 12. During the pushing process, the second release film 33 will automatically separate from the protective film 32. At the same time, the protective film 32 will be gradually pressed onto the screen. After the protective film 32 is completely adhered to the screen, the film pressing assembly 11 can be removed, and the first release film 31 can be peeled off the protective film 32.

[0052] Furthermore, in this embodiment, a guide slope 241 is formed at the end of the slide rail 24 near the limiting groove, making it easier for the user to place the film application component 1 into the end of the base 2. It is understood that a guide slope 241 can also be provided at the bottom of the upright plate 1112. The presence of various guide slopes 241 allows the user to better install the film application component 1 into the base 2, and enables the positioning post 22 to quickly align and lock with the corresponding structures such as the limiting hole 1222, achieving rapid film application. In this embodiment, a notch 25 communicating with the receiving groove 21 is also formed on the upper part of the base 2. The notch 25 makes it easier for the user to remove the electronic device 4 placed in the receiving groove 21. It is understood that one or more notches 25 can be provided in this embodiment, and this is not limited. The base 2 in this embodiment also has a lens clearance corresponding to the shape of the electronic device 4. The lens clearance can be a lens hole penetrating the base 2 to its receiving groove 21, which can prevent the lens of the electronic device 4 from being squeezed during the film application process.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
