[0028] Example:

[0029] like Figure 1-5 As shown, in this embodiment, the film sticking device is used to stick the soft film 3 to the electronic device 4, the soft film 3 includes a protective film 32 and a first release film 31 connected to one side of the protective film 32, and one end of the first release film 31 is provided with a positioning portion 311 for clamping the film clamping assembly 12; the film sticking device includes: a base 2, a film clamping assembly 12, the soft film 3 and a film pressing assembly 11; the base 2 is formed with a receiving groove 21 for placing the electronic device 4, and one end of the receiving groove 21 is provided with a first positioning structure; the film clamping assembly 12 has a second positioning structure adapted to the first positioning structure; when the film clamping assembly 12 holding the soft film 3 is clamped When the component 12 is installed in place with the base 2, the first positioning structure and the second positioning structure are limited in position; the film pressing assembly 11 includes a mounting seat 111, a pressing piece 112 installed on the mounting seat 111 and a limiting assembly 113; 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 seat 111, and to make the soft film 3 fit tightly against the pressing piece 112; the mounting seat 111 is detachably connected to the base 2 and is used to slide with the base 2; when the film is applied, the pressing piece 112 slides relative to the base 2 under the action of external force and presses the protective film 32 onto the screen of the electronic device 4.

[0030] Specifically, through the stable clamping of the positioning portion 311 by the film clamping assembly 12 and the limiting cooperation between the first positioning structure and the second positioning structure, the positioning portion 311 can be stably and accurately fixed on the base 2, thereby realizing accurate positioning of the soft film 3 and facilitating the installation of the soft film 3. In addition, the limiting assembly 113 can stabilize the position of the soft film 3 when the user folds and rolls up the soft film 3 along the outer periphery of the mounting seat 111, and make the soft film 3 fit tightly with the pressing piece 112, which can effectively prevent the deformation of the part of the protective film 32 that is being attached to the screen and generate bubbles. It can be seen that the film attachment device of the present application has a simple overall structure and a good positioning effect.

[0031] The soft film 3 in this embodiment also includes a second release film 33 connected to the side of the protective film 32 facing away from the first release film 31; that is, the second release film 33 is connected to the adhesive side of the protective film 32, and the second release film 33 is not connected to the positioning portion 311, and the positioning portion 311 is not connected to the protective film 32. When applying the film, first connect the soft film 3 to the film clamping assembly 12, and then install the film clamping assembly 12 connected with the soft film 3 into the film pressing assembly 11 (thereby achieving the initial positioning of the film applying assembly 1); then the film applying assembly 1 after the initial positioning is installed as a whole into the base 2. During the installation process, a small part of the second release film 33 and the protective film 32 can be torn off from the side close to the film clamping assembly 12, and the inner side of the torn part of the second release film 33 (the side attached to the protective film 32) can be abutted against the screen of the electronic device 4; then, the second release film 33 and the protective film 32 can be automatically separated by pushing the film pressing assembly 11, and at the same time, the protective film 32 is gradually pressed onto the screen; after the protective film 32 is completely attached to the screen, the first release film 31 can be torn off, and the operation is simple and convenient.

[0032] The base 2 of this embodiment also has a guide structure; the film pressing component 11 is used to slide with the guide structure. It can be understood that in this embodiment, the guide structure can only guide the film pressing component 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 component 11, so that the film pressing component 11 can press the protective film 32 on the top of the screen during the sliding process; of course, in some preferred embodiments, the guide structure not only guides the film pressing component 11, but also limits the film pressing component 11, that is, the position of the film pressing component 11 in the height direction can be limited by the guide structure. When applying the film, the user only needs to apply a thrust in the horizontal direction to the film pressing component 11. For example, a slide rail 24 can be set on the opposite sides of the base 2, and a limiting edge 114 corresponding to the slide rail 24 can be set at the bottom edge of the pressing component, so that the lower side of the slide rail 24 is abutted against the upper side of the limiting edge 114. In this way, the pressing component can slide along the slide rail 24 and complete the film application only under the horizontal thrust. By manufacturing the film pressing assembly 11 in this way, it can be ensured that the film pressing assembly 11 always provides a stable pressing force to the soft film 3 during the sliding process, and the film laminating effect is good.

[0033] In the first positioning structure and the second positioning structure of the present embodiment, one may be a positioning column 22 and the other may be a limiting hole 1222. For example, the first positioning structure is a positioning column 22 and the second positioning structure is a limiting hole 1222. One or more limiting holes 1222 may be provided, and the number of positioning columns 22 is equal to the number of limiting holes 1222. Through the stable clamping of the positioning portion 311 by the film clamping assembly 12 and the limiting cooperation between the positioning column 22 and the limiting hole 1222, the positioning portion 311 can be stably and accurately fixed on the base 2, thereby realizing accurate positioning of the soft film 3 and facilitating the attachment of the soft film 3. It can be seen that the film attachment device of the present application has a simple overall structure and a good positioning effect.

[0034] In this embodiment, the mounting seat 111 includes a seat body 1111 and vertical plates 1112 connected to both sides of the seat body 1111; the bottom end of each vertical plate 1112 is used for sliding cooperation with the base 2. The bottom ends of the two vertical plates 1112 are respectively connected to the limiting edges 114, and the limiting edges 114 are located on the sides of the two vertical plates 1112 that are close to each other; the opposite sides of the base 2 are also formed with slide rails 24, and the slide rails 24 are used for sliding cooperation with the corresponding limiting edges 114. The bottom side of the film pressing assembly 11 is also provided with a pressing piece 112, and during the relative sliding process between the slide rail 24 and the limiting edge 114, the pressing piece 112 can press the protective film 32 in the soft film 3 onto the screen of the electronic device 4. The seat body 1111, the vertical plates 1112 and the limiting edge 114 can be obtained by an integrated injection molding process, which has good structural stability and low production cost.

[0035] 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, when in use, the film sticking assembly 1 can be first installed into the base 2 from the upper end of the base 2 (above the positioning column 22), and the positioning column 22 will be inserted into the limiting hole 1222 and fit with the limiting hole 1222, thereby achieving the fixation between the film clamping assembly 12 and 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, and at the same time, the protective film 32 will be gradually pressed onto the screen. After the protective film 32 is completely attached to the screen, the film pressing assembly 11 is removed, and the first release film 31 is torn off the protective film 32.

[0036] In this embodiment, the film pressing assembly 11 includes a mounting seat 111 and a pressing piece 112 installed at the bottom of the mounting seat 111. The pressing piece 112 is used to press the protective film 32 onto the screen of the electronic device 4 during the relative sliding of the mounting seat 111 and the base 2. The pressing piece 112 and the mounting seat 111 can be connected in a movable manner or in a rolling manner. In some embodiments, the pressing piece 112 is a pressing plate 1121 fixed on the seat body 1111, and / or the pressing piece 112 is a first roller 1122 connected between the two vertical plates 1112.

[0037] Furthermore, in the present embodiment, the pressing member 112 includes a pressing plate 1121 disposed at the bottom end of the mounting seat 111. A pressing surface adapted to the electronic device 4 is formed on the bottom side of the pressing plate 1121. During the movement of the mounting seat 111, the pressing surface can press the protective film 32 onto the screen, and the film pasting efficiency is high. Further, in some embodiments, concave surfaces are formed at both ends of the pressing plate 1121, and the concave surfaces are used to press the edge of the protective film 32 onto the curved area of ​​the screen of the electronic device 4. That is, the electronic device 4 in the present embodiment can be a curved screen mobile phone, and correspondingly, concave surfaces adapted to the shape of the curved screen mobile phone can be provided on both sides of the pressing surface, so that the protective film 32 can be accurately and completely pasted on each screen area of ​​the curved screen mobile phone.

[0038] In this embodiment, the pressing member 112 also includes a first roller 1122 connected between the two vertical plates 1112, and the first roller 1122 is located at the bottom of the seat body 1111; the bottom end of each vertical plate 1112 is used to slide with the base 2. In this embodiment, the seat body 1111 and the vertical plate 1112 are connected as a whole, that is, the seat body 1111 and the vertical plate 1112 can be obtained by an integral injection molding process, which has good structural stability and low production cost. A clearance space adapted to the shape of the first roller 1122 is formed on the bottom side of the seat body 1111. During the relative sliding of the mounting seat 111 and the base 2, the surface of the first roller 1122 rolls and rubs against the surface of the first release film 31, and the protective film 32 is pressed onto the screen. It can be understood that in some embodiments, the film pressing assembly 11 can only be provided with the pressing plate 1121 or only be provided with the first roller 1122, and the film pressing assembly 11 can also be provided with the pressing plate 1121 and the first roller 1122 at the same time.

[0039] In one embodiment, the pressing plate 1121 and the first roller 1122 can be provided at the same time, and the pressing plate 1121 can be located in front of the first roller 1122 in the forward direction, and the pressing surface of the pressing plate 1121 can be flush with the lowest point of the roller surface to ensure that the protective film 32 fits tightly to the screen. Of course, in some other specific embodiments, the pressing surface of the pressing plate 1121 can also be slightly higher than the lowest point of the roller surface. In this case, the pressing plate 1121 mainly plays a guiding role and a role in stabilizing the position of the soft film 3, and the first roller 1122 mainly plays a pressing role. Such a setting can also achieve precise fitting of the protective film 32 to the screen.

[0040] Furthermore, in the present embodiment, a first magnetic member is provided in the film clamping assembly 12, and a second magnetic member is provided on the bottom side of the seat body 1111, and the second magnetic member is used to attract the first magnetic member to achieve the initial positioning between the seat body 1111 and the film clamping assembly 12. The film clamping assembly 12 includes a first fixing member 121 and a second fixing member 122 that are detachably connected, and the first fixing member 121 and the second fixing member 122 cooperate to clamp the end of the soft film 3, and the first fixing member 121 and the second fixing member 122 can clamp the positioning portion 311 by means of a snap connection and / or magnetic matching. The first magnetic member is embedded in the first fixing member 121, and the second magnetic member is embedded on the bottom side of the seat body 1111, and the position of the second magnetic member is different from the position of the pressing member 112. In the direction of sliding and pressing of the film pressing assembly 11, the second magnetic member is located behind the pressing member 112. Through the interaction between the first magnetic attraction member and the second magnetic attraction 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.

[0041] In this embodiment, the second magnetic attraction member is embedded in the bottom side of the seat body 1111, and the bottom ends of the two vertical plates 1112 are respectively connected to the limiting edge 114, and the limiting edge 114 is located on the side of the two vertical plates 1112 close to each other; the opposite sides of the base 2 are also formed with slide rails 24, which are used to slide with the corresponding limiting edge 114. During the relative sliding of the slide rail 24 and the limiting edge 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 seat body 1111, the vertical plate 1112 and the limiting edge 114 can be obtained by an integral injection molding process, which has good structural stability and low production cost.

[0042] In this embodiment, a third magnetic member is further provided in the 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 member away from the second magnetic member attracts the third magnetic member, so that the first fixing member 121 and the second fixing member 122 are close to each other and clamp the soft film 3. That is, after the positioning portion 311 of the soft film 3 is placed between the first fixing member 121 and the second fixing member 122, the first fixing member 121 and the second fixing member 122 can be attracted to each other by the magnetic attraction force between the first magnetic member and the third magnetic member, so as to clamp the soft film 3, which is convenient to use.

[0043] In this embodiment, the first fixing member 121 is provided with a clearance hole 1211, and the second fixing member 122 has a limiting portion 1221 adapted to the clearance hole 1211; the limiting portion 1221 is used to sequentially pass through the positioning hole 312 and the clearance hole 1211 at the end of the soft film 3 to achieve the limitation of the soft film 3 and the first fixing member 121. That is, the positioning portion 311 is provided with a positioning hole 312 for the limiting portion 1221 to pass through, and the shapes of the positioning hole 312 and the limiting portion 1221 are just adapted; when in use, the position of the positioning portion 311 in the horizontal direction can be limited through the cooperation between the limiting portion 1221 and the clearance hole 1211, thereby achieving accurate positioning of the soft film 3, and further enhancing the connection stability between the first fixing member 121 and the second fixing member 122. Of course, in some other implementations, the clearance hole 1211 may also be provided on the second fixing member 122 , and the limiting portion 1221 may be provided on the first fixing member 121 , which is not limited here.

[0044] In this embodiment, a limiting groove adapted to the film clamping assembly 12 is provided at the bottom of the seat body 1111 and / or above the base 2; during the initial positioning, the film clamping assembly 12 is engaged 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 seat body 1111, and the first limiting groove 1114 is used to limit the first fixing member 121, so that during the initial positioning, the connection between the mounting seat 111 and the film clamping assembly 12 is more stable. A second limiting groove 23 is provided above the base 2, and the shape and size of the second limiting groove 23 are adapted to the second fixing member 122. The positioning column 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.

[0045] Further, in the present embodiment, a guide slope 241 is formed at one end of the slide rail 24 near the limiting groove, which makes it more convenient for the user to put the film assembly 1 into the end of the base 2. It is understandable that a guide slope 241 can also be set at the bottom of the vertical plate 1112. Through the setting of each guide slope 241, the user can better load the film assembly 1 into the base 2 and quickly align and clamp the corresponding structures such as the positioning column 22 and the limiting hole 1222 to achieve rapid film application. In the present embodiment, a notch 25 connected to the accommodating groove 21 is also formed above the base 2. The setting of the notch 25 can make it more convenient for the user to take out the electronic device 4 placed in the accommodating groove 21. It is understandable that one or more notches 25 in the present embodiment can be set, and there is no limitation here. The base 2 of the present embodiment is also provided with a lens avoidance position corresponding to the shape of the electronic device 4. The lens avoidance position can be a lens hole that runs through the base 2 to the accommodating groove 21, which can prevent the lens from being squeezed during the film application process.

[0046] In this embodiment, the film sticking assembly 1 also includes a limiting assembly 113 installed on the forward side or the top of the seat 1111, and the limiting assembly 113 is used to stabilize the soft film 3 so that the soft film 3 and the pressing piece 112 are tightly attached during the film sticking process. Specifically, the limiting assembly 113 can be connected between the two vertical plates 1112, and the limiting assembly 113 is located on the forward side or the top of the seat 1111. That is, during the sticking 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 be surrounded by the outside of the mounting seat 111, and the limiting assembly 113 is used for limiting, so as to avoid the unattached part of the soft film 3 from drooping and swinging during the film sticking process, thereby affecting the film sticking process. At the same time, the limiting assembly 113 can also tighten the soft film 3, that is, the soft film 3 is appropriately tightened and tightly attached to the pressing piece 112, which can effectively avoid the generation of bubbles.

[0047] Furthermore, in the present embodiment, the limiting assembly 113 includes a rotating shaft 1131, a second roller 1132 and a double torsion spring 1133, the rotating shaft 1131 is connected between the two vertical plates 1112, and 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 a spring portion 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 on the outer side of the second roller 1132, and is used to cooperate with the second roller 1132 to clamp the soft film 3 during the film pasting 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 seat 111. The fixing of the spring part makes the first abutting part have a restoring force toward the second roller 1132, so that when the soft film 3 is not installed, the first abutting part automatically abuts against the outer side of the second roller 1132 under the action of the restoring force. When 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 sticking assembly 1, the second roller 1132 and the double torsion spring 1133 can cooperate to clamp the soft film 3 firmly.

[0048] Furthermore, in this embodiment, the limiting assembly 113 further includes a limiting buckle 1134, which includes a second abutting portion 11341 and a buckling portion 11342 connected to the second abutting portion 11341, and a buckling groove 1113 adapted to the buckling portion 11342 is provided on the top of the seat body 1111; the second abutting portion 11341 is used to form abutment with the soft film 3 when the buckling portion 11342 is buckled into the buckling groove 1113, and the soft film 3 is attached to the pressing member 112. The limiting buckle 1134 can be arranged above the mounting seat 111, and can further stabilize the position of the soft film 3.

[0049] Furthermore, in this embodiment, the limit buckle 1134 also includes a connecting portion 11343 connected to the second abutting portion 11341, and a mounting groove is also provided on the side of the vertical plate 1112 facing the seat body 1111. Both ends of the connecting portion 11343 have connecting columns adapted to the mounting grooves, and the connecting columns are used to rotate with the mounting grooves to enable the limit buckle 1134 to move to the first position or the second position; when the limit buckle 1134 moves to the first position, the buckling portion 11342 and the buckling groove 1113 are buckled and fixed; when the limit buckle 1134 moves to the second position, the second abutting portion 11341 and the seat body 1111 are separated from each other.

[0050] Specifically, the limit buckle 1134 is hinged between the two vertical plates 1112. When the user applies forces in different directions to the limit buckle 1134, the limit buckle 1134 can flip, that is, the limit buckle 1134 can move to the first position or the second position under the action of external force. When the limit buckle 1134 moves to the first position, the buckle portion 11342 is just buckled and fixed with the buckle groove 1113, and at the same time, the second abutment portion 11341 can press against the surface of the seat body 1111 to clamp the soft film 3 firmly, thereby realizing the position restriction of the soft film 3. When the limit buckle 1134 moves to the second position, the second abutment portion 11341 is separated from the seat body 1111, which can facilitate the user to install the soft film 3 (conveniently put the end of the soft film 3 away from the film clamping assembly 12 between the limit buckle 1134 and the seat body 1111). Furthermore, in this embodiment, the connection portion 11343 and the second abutting portion 11341 are enclosed to form a clearance opening 1134a for the soft film 3 to pass through, and the existence of the clearance opening 1134a can limit the position of the soft film 3 to a certain extent, and is more convenient for users to operate. In this embodiment, an operating portion 11344 can also be set on the limit buckle 1134, and the operating portion 11344 is connected to the second abutting portion 11341, so that the user can easily turn the limit buckle 1134.

[0051] 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 in the protection scope of the present invention.
