Description

[Technical field]

[0001] The utility model relates to the technical field of electronic equipment accessories, in particular to a film sticking device and a film sticking component. [Background technology]

[0002] In order to improve the film sticking effect, traditional film sticking boxes often have a roller in contact with the protective film. The roller is used to roll the protective film to improve the adhesion of the protective film and squeeze out the bubbles generated during the film sticking process.

[0003] However, most of the rollers of existing film sticking boxes cannot achieve up and down floating relative to the protective film, resulting in that the up and down distance of the roller relative to the protective film cannot be adjusted during the entire film sticking rolling process. If the up and down distance is fixed, it is difficult to ensure that the film can be effectively rolled and stuck throughout the entire film sticking rolling process; even if some film sticking boxes use springs to achieve up and down floating of the roller relative to the protective film, such a setting structure is too complicated, which increases the difficulty of production and assembly.

[0039] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0041] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0042] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0043] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0044] Please combine Figures 1 to 5 The first embodiment of the utility model provides a film sticking device 1, which includes a bottom shell 20 and an operating component 30. The bottom shell 20 is slidably connected to the operating component 30. The operating component 30 includes a bracket shell 31, a floating plate 32 and a film pressing component 33. One end of the floating plate 32 is connected to the bracket shell 31, and the film pressing component 33 is connected to the floating plate 32. The film pressing component 33 is arranged on the side of the floating plate 32 facing the bottom shell 20.

[0045] It can be understood that, since only one end of the floating plate 32 is connected to the bracket shell 31, the floating plate 32 and the bracket shell 31 form a cantilever beam structure. When subjected to external force, the floating plate 32 can be displaced relative to the bracket shell 31; since the film pressing assembly 33 is arranged on the side of the floating plate 32 facing the bottom shell 20, the film pressing assembly 33 is connected to the floating plate 32, and thus driven by the floating plate 32, the film pressing assembly 33 can also float up and down relative to the bottom shell 20, and the up and down floating makes the film pressing force applied by the film pressing assembly 33 uniform; the film pressing assembly 33 is connected to the floating plate 32, and the bottom shell 20 is slidably connected to the operating assembly 30, so that when an external force is applied to the operating assembly 30 and the operating assembly 30 slides with the bottom shell 20, the film pressing assembly 33 can move accordingly The film pressing component 33 moves and applies pressure; since the film pressing component 33 can float up and down relative to the bottom shell 20, during the entire rolling process, the film pressing component 33 can automatically adjust the upper and lower distances of the roller 331 relative to the device to be filmed according to the force conditions. The film pressing component 33 floats up and down to achieve effective pressure and adhesion during the entire process of film application. During the film application process, the operating component 30 can be pushed and pulled back and forth smoothly, and the entire film application process is smooth and stable, which effectively improves the film application effect and squeezes out the bubbles generated during the film application process. The floating plate 32 and the bracket shell 31 form a cantilever beam structure to achieve up and down floating, and the structure is simple and easy to produce and assemble.

[0046] Specifically, as a preferred embodiment, the upward or downward floating range of the film pressing component 33 relative to the bracket shell 31 is less than or equal to 2 mm. It can be understood that by setting the upward or downward floating range of the film pressing component 33 relative to the bracket shell 31 to be less than or equal to 2 mm, it is ensured that the upward and downward floating range of the film pressing component 33 is maintained at a relatively small floating level, and the relatively small floating level of the film pressing component 33 is automatically adjusted for the specific film pasting pressure process, so that the uniform film pasting pressure intensity is achieved.

[0047] Please combine Figure 2 and Figure 3 Furthermore, the film pressing assembly 33 includes a roller 331 and a rotating shaft 332. The film pressing assembly 33 is rotatably connected to the floating plate 32. The roller 331 is sleeved on the rotating shaft 332. Limiting holes 321 corresponding to the rotating shaft 332 are opened at both ends of the floating plate 32. The rotating shaft 332 is rotatably connected to the limiting holes 321.

[0048] It can be understood that by setting the film pressing assembly 33 including a roller 331 and a rotating shaft 332, the film pressing assembly 33 is rotatably connected to the floating plate 32, so that the film pressing assembly 33 can roll and apply pressure more easily; the roller 331 is set to be sleeved on the rotating shaft 332, and the rotating shaft 332 is rotatably connected to the limiting hole 321. The rotating shaft 332 and the limiting hole 321 are rotatably connected to realize the rotation of the film pressing assembly 33 relative to the floating plate 32, and the shaft-hole cooperation makes the rotation smoother; the roller 331 is sleeved on the rotating shaft 332, so that the rotating shaft 332 drives the roller 331 to rotate, and the roller 331 can be displaced relative to the bottom shell 20, thereby playing a good rolling effect.

[0049] Preferably, as a specific implementation, the rotating shaft 332 is a stainless steel round rod; the roller 331 is made of silicone. The stainless steel round rod can ensure that the rotating shaft 332 can rotate flexibly, and will not cause the operating component 30 to be pushed and pulled unsmoothly due to rust; the roller 331 is made of silicone, which has the characteristics of being soft and easy to deform, and can make the pressure applied by the roller 331 more uniform. It should be noted that the above is only an example, and other types of implementations are not limited here.

[0050] Please combine Figure 1 , Figure 3-Figure 5 Furthermore, the bracket shell 31 includes a plurality of bracket enclosures 312, which enclose a receiving space 313. The floating plate 32 is arranged in the receiving space 313. The end defining the connection between the floating plate 32 and the bracket enclosure 312 is a fixed end 323. The remaining end surface of the floating plate 32 except the fixed end 323 is a floating end 324. A gap 325 is left between the floating end 324 and the inner wall surface of the bracket enclosure 312.

[0051] It can be understood that by setting the floating plate 32 so that only the fixed end 323 of the floating plate 32 is connected to the bracket enclosure 312, the remaining end surface on the peripheral side of the floating plate 32 is the floating end 324, and a gap 325 is left between the floating end 324 and the inner wall surface of the bracket enclosure 312. The existence of the gap 325 ensures that the floating plate 32 can float up and down flexibly without obstruction or constraint; the cantilever beam structure formed by the floating plate 32 being connected to the bracket enclosure 312 at only the fixed end 323 allows the floating plate 32 to float up and down flexibly according to the force.

[0052] Please combine Figures 1 to 3 Furthermore, two opposite sides of the bottom shell 20 are provided with slide grooves 21 , and the bracket shell 31 is provided with sliders 311 corresponding to the slide grooves 21 , and the sliders 311 are slidably connected to the slide grooves 21 .

[0053] It can be understood that by opening the slide groove 21 on the opposite sides of the bottom shell 20, the bracket shell 31 is provided with a slider 311 corresponding to the slide groove 21, the slide groove 21 plays a limiting role for the slider 311 on the bracket shell 31, and the slider 311 can slide freely in the slide groove 21 to achieve a sliding connection between the slider 311 and the slide groove 21; the free sliding of the slider 311 in the slide groove 21 can drive the operating component 30 to slide relative to the bottom shell 20 to achieve rolling, squeeze out the bubbles generated in the film pasting process, so that the film pasting equipment and the film body are more closely fitted, thereby improving the film pasting effect.

[0054] Please combine Figure 1 and Figure 5 Furthermore, the floating plate 32 is an arched floating plate 322 , and the arched floating plate 322 bulges in a direction away from the bottom shell 20 .

[0055] It can be understood that by setting the arched floating plate 322 to bulge in the direction away from the bottom shell 20 to form an arched structure, the arched floating plate 322 forms a depression on the side close to the bottom shell 20, which can play a role in storing and protecting the film pressing assembly 33. At the same time, the arch formed by the bulge is more prominent, which is convenient for the user to apply external force to it, thereby conveniently and smoothly pushing and pulling the operating assembly 30 to roll back and forth.

[0056] Please combine Figure 1 , Figure 2 and Figure 6 Furthermore, the slider 311 includes a first slider 3111 and a second slider 3112, defining the end where the slide groove 21 is connected to the operating component 30 as the connecting end 211, the first slider 3111 and the second slider 3112 are arranged in sequence in a direction away from the connecting end 211, and the groove wall of the slide groove 21 is provided with a notch 212 corresponding to the second slider 3112.

[0057] It can be understood that by providing a notch 212 corresponding to the second slider 3112 in the groove wall of the slide groove 21, the operating component 30 rotates with the first slider 3111 as the rotation center. Since the groove wall of the slide groove 21 provides a notch 212 corresponding to the second slider 3112, the second slider 3112 can be free from the constraint of the slide groove 21 and rotate from the notch 212 to the outside of the slide groove 21, so that the operating component 30 can be rotated and opened to avoid obstruction, which can provide a larger operating space for the installation of the membrane body and improve the convenience and flexibility of the membrane body installation.

[0058] Please continue to combine Figure 1 , Figure 2 and Figure 6 Furthermore, the bottom shell 20 is provided with a receiving groove 22 , and a fixing member 23 is provided on the side of the bottom shell 20 close to the film pressing assembly 33 , and the fixing member 23 is arranged around the receiving groove 22 .

[0059] It can be understood that by providing the receiving groove 22, the mobile phone can be accommodated and fixed when the film is applied, preventing the film application position from deviating due to the force displacement of the film application device, thereby affecting the film application effect. The fixing part 23 is provided around the receiving groove 22, which can play a fixing role and prevent the fixed position from deviating, thereby further improving the film application effect.

[0060] Specifically, as a preferred embodiment, the fixing member 23 includes a first fixing member 231 and a second fixing member 232, wherein the first fixing member 231 is disposed at one end of the bottom shell 20 close to the operating assembly 30, and the second fixing member 232 is disposed at one end of the bottom shell 20 away from the operating assembly 30. It can be understood that the first fixing member 231 and the second fixing member 232 are disposed at both ends of the bottom shell 20, and can be fixed from multiple directions and angles, so that the fixing force on the film body is more uniform, and the deformation of the film body due to uneven force is avoided, which affects the film sticking effect.

[0061] Please combine Figure 1 and Figure 7 The second embodiment of the utility model provides a film sticking device 1 , which is different from the film sticking device 1 provided by the first embodiment in that: the film pressing assembly 33 is a film pressing block 333 , and the film pressing block 333 is fixedly connected to the floating plate 32 .

[0062] It can be understood that by setting the film pressing component 33 as a film pressing block 333, and the film pressing block 333 is fixedly connected to the floating plate 32, it is possible to use a relatively simple structure to realize that the floating plate 32 drives the film pressing block 333 to float up and down, and during the film laminating process, the operating component 30a is pushed or pulled to move, and the floating plate 32 floats up and down, so that the film pressing force applied by the film pressing block 333 is uniform.

[0063] Specifically, as a preferred embodiment, the film pressing block 333 is made of EVA material, and the film pressing block 333 and the floating plate 32 are fixed by double-sided adhesive. EVA has high resilience and tensile strength, good deformation performance, and can fully contact the film body and apply relatively uniform pressure. It should be noted that the above is only an example, and other types of embodiments are not limited here.

[0064] Please continue to combine Figure 1 and Figure 7 Furthermore, the film pressing block 333 includes a notch 3332 and a protrusion 3331. The notch 3332 is opened in the middle of the film pressing block 333 away from the floating plate 32. The protrusion 3331 is arranged at both ends of the notch 3332. The notch 3332 and the protrusion 3331 are connected and transitioned by an arc.

[0065] It can be understood that by opening a slot 3332 on the side of the film pressing block 333 away from the floating plate 32, the protrusions 3331 are arranged at both ends of the slot 3332, and the two ends of the slot 3332 are connected and transitioned to the protrusions 3331 in an arc shape, so that the arc structure of the edge of the slot 3332 can fit the curved edge of the curved screen, and pressure is applied to the edge of the curved screen when the film is applied, thereby improving the film application effect of the curved screen device to be filmed.
