Description

Technical Field

[0001] The utility model relates to the technical field of film sticking devices, in particular to a film sticking component. Background Art

[0002] Electronic products with screens, such as mobile phones and computers, currently available on the market generally require a layer of protective film to be attached to the surface of the screen to protect the screen. Since the screen is often touched, the protective film will be damaged after a period of use, so the protective film needs to be replaced frequently. The roller-type film-applying device is a new type of film-applying device, which positions the screen to be filmed and the protective film by setting a positioning structure, and sets a roller to roll the protective film, so that the protective film can be attached to the screen to be filmed from one end to the other end in sequence, so that the protective film can be accurately and efficiently attached to the product to be filmed, and prevents the generation of bubbles during the film-applying process.

[0003] The protective film and roller-type film sticking device in the film sticking assembly are generally packaged together and sold to users. The protective film and roller-type film sticking device in the film sticking assembly currently sold on the market are usually packaged separately and then packaged together in a packaging box. Since the protective film is not pre-installed in the roller-type film sticking device, the user needs to install the protective film in the roller-type film sticking device before the film sticking operation can be performed, which increases the user's operation steps and is inconvenient for the film sticking operation; moreover, since the protective film needs to be packaged separately, the packaging cost is increased.

[0033] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] The terms "first", "second", "third", "fourth" and the like (if any) in the description and claims of the present invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0035] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed by the utility model.

[0036] like Figures 1 to 10 As shown, the film sticking assembly provided by the embodiment of the utility model includes a film sticking device and a protective film 3. Among them, the film sticking device includes a base 1 and a rolling assembly 2, the base 1 includes a bottom plate 11, two side plates 12 respectively arranged on opposite sides of the bottom plate 11, and a first positioning platform 13 and a second positioning platform 14 respectively arranged at opposite ends of the bottom plate 11, the first positioning platform 13 and the second positioning platform 14 are both located between the two side plates 12, and the bottom plate 11, the side plate 12, the first positioning platform 13 and the second positioning platform 14 are an integrated structure. The bottom plate 11, the two side plates 12, the first positioning platform 13 and the second positioning platform 14 are surrounded to form a positioning groove 10 for placing the product to be filmed (not shown in the figure) (the product to be filmed can be a mobile phone, a tablet, etc.). The protective film 3 is arranged above the positioning groove 10, and the protective film 3 is located between the base 1 and the rolling assembly 2.

[0037] The first positioning platform 13 is provided with a first positioning structure 16, and the second positioning platform 14 is provided with a second positioning structure 17. The first positioning structure 16 and the second positioning structure 17 are respectively protruded on the first positioning platform 13 and the second positioning platform 14. The two ends of the protective film 3 along its length direction are respectively the first end and the second end, and the first end and the second end of the protective film 3 correspond to the first positioning platform 13 and the second positioning platform 14 respectively; the first end and the second end of the protective film 3 are respectively provided with a first positioning hole 311 and a second positioning hole 312, and the first positioning structure 16 and the second positioning structure 17 are respectively sleeved in the first positioning hole 311 and the second positioning hole 312 (that is, the first end of the protective film 3 is hung on the first positioning structure 16, and the second end of the protective film 3 is hung on the second positioning structure 17), so as to position the protective film 3, and then realize the positioning between the protective film 3 and the product to be filmed.

[0038] The first positioning structure 16 includes a positioning portion 161 and a limiting portion 162 protruding from the positioning portion 161. The positioning portion 161 is arranged on the first positioning platform 13. The positioning portion 161 is sleeved in the first positioning hole 311 (that is, the first end of the protective film 3 is hung on the positioning portion 161), and the first end of the protective film 3 is clamped by the limiting portion 162, so that the first end of the protective film 3 is fixed to the first positioning structure 16, that is, the first end of the protective film 3 will not easily fall off from the base 1, so that the protective film 3 can be pre-installed in the film pasting device (because the first positioning structure on the existing film pasting device does not have the function of locking and fixing the protective film, the protective film is pre-installed in the film pasting device. It is easy to fall off during transportation, so it is not suitable for packaging with the film pasting device and needs to be packaged separately). It should be noted that during the film pasting process, the second end of the protective film 3 needs to be uncovered first (such as Figure 6 As shown, the first end of the protective film 3 does not need to be removed. When the second end of the protective film 3 is uncovered, the protective film 3 will be rotated open at its first end) so that the product to be pasted can be placed in the positioning groove 10. Therefore, the second positioning structure 17 generally does not lock and fix the second end of the protective film 3.

[0039] The rolling assembly 2 is located above the base 1, and includes a base 21 and a roller 22, and the roller 22 is rotatably connected to the base 21. Slide rails 15 are provided on both side panels 12, and sliding parts 23 (the sliding parts 23 can be provided on the base 21 and / or the roller 22) that match the slide rails 15 are provided on opposite sides of the rolling assembly 2, and the roller 22 is provided corresponding to the sliding parts 23. The sliding parts 23 on opposite sides of the rolling assembly 2 are respectively slidably connected to the slide rails 15 on the two side panels 12, so that the base 21 and the roller 22 can slide along the slide rails 15.

[0040] The film sticking assembly provided by the utility model is provided with a limiting portion 162 on the positioning portion 161 of the first positioning structure 16. When the first end of the protective film 3 is sleeved on the first positioning structure 16, the first end of the protective film 3 can be clamped by the limiting portion 162 to fix the first end of the protective film 3 to the first positioning structure 16, that is, the protective film 3 can be pre-fixed in the film sticking device. On the one hand, the user does not need to install the protective film 3 in the film sticking device by himself when sticking the film, which saves the user's operating steps and facilitates the film sticking operation. At the same time, the protective film 3 is pre-installed in the film sticking device, and the protective film 3 does not need to be packaged separately, which can save packaging costs.

[0041] like Figures 2 to 5As shown, as an embodiment, the limiting portion 162 includes a first protrusion 162A and a second protrusion 162B protruding from the positioning portion 161, and the first protrusion 162A and the second protrusion 162B extend and protrude from the positioning portion 161 in different directions. The first protrusion 162A and the second protrusion 162B cooperate with each other to limit the protective film 3 from different directions, so that the protective film 3 cannot be separated from the limiting portion 162 in a certain direction, so that the first end of the protective film 3 can be clamped by the limiting portion 162.

[0042] like Figures 2 to 5 As shown, as an embodiment, the first protrusion 162A and the second protrusion 162B extend and protrude in opposite directions. Specifically, in this embodiment, the first protrusion 162A extends and protrudes from the positioning portion 161 toward the side away from the second positioning platform 14, and the second protrusion 162B extends and protrudes from the positioning portion 161 toward the side close to the second positioning platform 14, so that the first protrusion 162A and the second protrusion 162B can have a good limiting effect on the protective film 3 and facilitate the assembly of the protective film 3 and the first positioning structure 16. Of course, in other embodiments, the first protrusion 162A and the second protrusion 162B can also be other protruding directions.

[0043] like Figures 2 to 5 As shown, as an embodiment, relative to the horizontal plane, the first protrusion 162A extends horizontally, or extends obliquely downward, or extends obliquely upward; the second protrusion 162B extends horizontally, or extends obliquely downward, or extends obliquely upward.

When the sliding part 23 slides to the end of the slide rail 15 close to the first positioning platform 13 (i.e., as shown in FIG. Figure 1The housing 211 can be rotated and opened relative to the base 1, so that after the protective film 3 is rotated and uncovered, the product to be film-coated can be placed in the positioning groove 10. Specifically, in this embodiment, the slide rail 15 includes a turning track 151, which is arranged corresponding to the first positioning platform 13, and the turning track 151 is extended downward. When the sliding part 23 slides onto the turning track 151, the sliding part 23 can slide downward along the turning track 151. At this time, the sliding part 23 can rotate relative to the base 1 at the turning track 151, that is, the housing 211 can rotate relative to the base 1.

[0048] like Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, as an embodiment, the sliding part 23 is arranged on opposite sides of the housing 211; the slide rail 15 is an outer rail, and the slide rail 15 is arranged at the top side of the side plate 12, and the slide rail 15 protrudes outward compared to the side plate 12; that is, the housing 211 is directly slidably connected to the base 1. Of course, in other embodiments, the slide rail 15 and the sliding part 23 can also be other structural forms, for example, the slide rail 15 is a slide groove (not shown) arranged on the inner wall of the side plate 12, and the sliding part 23 is a rotating shaft 221 at both ends of the roller 22, and the rotating shaft 221 is located in the slide groove and can slide along the slide groove, that is, the roller 22 is directly slidably connected to the base 1.

[0049] Of course, in other embodiments, the base 21 may also be in other structural forms. Fig.11 As shown, the base 21 includes a sliding seat 212 and a handle 213, the roller 22 is rotatably connected to the sliding seat 212, and the sliding parts 23 are arranged on opposite sides of the sliding seat 212, that is, the sliding seat 212 is directly slidably connected to the base 1; the handle 213 is rotatably connected to the sliding seat 212, and the user pulls the handle 213 to drive the sliding seat 212 and the roller 22 to move. For another example, Fig.12 As shown, the base 21 includes a sliding seat 212 and a cover shell 214, the cover shell 214 can cover the base 1, the roller 22 is rotatably connected to the sliding seat 212, and the sliding part 23 is arranged on opposite sides of the sliding seat 212, that is, the sliding seat 212 is directly slidably connected to the base 1; the cover shell 214 is rotatably connected to the sliding seat 212, and the user pulls the cover shell 214 to drive the sliding seat 212 and the roller 22 to move.

[0050] like Figure 1 and Figure 2As shown, as an embodiment, a hand buckle 18 is provided on one side of the first positioning platform 13 away from the positioning groove 10, and the hand buckle 18 is connected to the base 1 (the hand buckle 18 and the base 1 can be rotatably connected or fixedly connected), and the hand buckle 18 serves as a hand buckle position of the base 1. A hand buckle groove 210 is provided on the shell 211, and the hand buckle groove 210 is used for the user to pull the shell 211 by hand.

[0051] Specifically, when applying the film, the film applying device is placed on a tabletop (such as a desktop), the user holds the hand buckle 18 with one hand to keep the base 1 fixed, and the user places the other hand in the hand buckle groove 210 and pulls the shell 211 to move the rolling assembly 2 toward the side close to the second positioning platform 14. At this time, the roller 22 moves while rolling the protective film 3, thereby squeezing the protective film 3 and attaching it to the product to be applied.

[0052] like Figure 2 and Figure 3 As shown, as an embodiment, a slope 161A for contacting the roller 22 is provided on the side of the two outermost positioning portions 161 facing the positioning groove 10. When the roller 22 moves toward the end of the base 1 close to the first positioning platform 13, after the roller 22 contacts the slope 161A, the roller 22 can climb upward along the slope 161A, so that the roller 22 can smoothly cross the first positioning structure 16 and move to the side of the first positioning platform 13 away from the positioning groove 10.

[0053] like Figures 2 to 8 As shown, as an embodiment, the protective film 3 includes an upper protective film 31 (also known as a positioning film), a protective film body 32, a lower protective film 33 and a pull-out strip 34 which are stacked in sequence from top to bottom; wherein the protective film body 32 is generally made of tempered glass or other materials, and the protective film body 32 is used to finally be attached to the product to be attached, while the upper protective film 31 and the lower protective film 33 only protect the protective film body 32 and will not be attached to the product to be attached.

[0057] like Figures 2 to 8 As shown, as an embodiment, a notch 315 is provided on one end of the upper protective film 31 close to the second positioning platform 14, and the notch 315 is provided corresponding to the extension portion 342. The width W2 of the extension portion 342 is greater than the width W1 of the notch 315, and a notch 343 is provided on the side of the pull-out strip 34 (specifically, the notch 343 is provided on the side of the pull-out strip 34 on opposite sides), and the notch 343 is located at the connection position between the extension portion 342 and the main body 341, and the width W3 of the pull-out strip 34 at the notch 343 is less than or equal to the width W1 of the notch 315; the extension portion 342 can be stuck in the notch 315 through the notch 343 after reverse folding, thereby preventing the extension portion 342 from turning over by itself and detaching from the protective film 31.

[0058] like Figure 8 As shown, as an embodiment, a half-broken line 31A (also known as a ridge line) is provided at one end of the upper protective film 31 close to the first positioning platform 13, and a first fold line 33A is provided on the outer convex portion 331 of the lower protective film 33, and the half-broken line 31A corresponds to the first fold line 33A, so that the protective film 3 can be turned over along the half-broken line 31A and the first fold line 33A (i.e., as shown in FIG. Figure 6 A second fold line 31B is provided at the connection position between the lug 313 and the upper protective film 31, and the lug 313 can be turned over and folded along the second fold line 31B. A third fold line 34A is provided at the connection position between the extension part 342 and the main body part 341, and the extension part 342 can be turned over and folded along the third fold line 34A.

[0059] As an implementation method, the method for using the film sticking device is as follows:

[0060] 1. Before film application, the protective film 3 is pre-assembled in the film application device, and the lugs 313 and the extensions 342 are both in a folded state and stored in the film application device (i.e. Figure 5 status shown).

[0061] 2. When performing the film sticking operation, first rotate and open the housing 211 to expose the protective film 3; then flip the protective film 3 over and uncover it (i.e. Figure 6 The positioning groove 10 is exposed, and the product to be laminated is placed in the positioning groove 10.

[0062] 3. Reversely rotate the protective film 3 so that the protective film 3 covers the product to be filmed, then flip and unfold the lug 313 and the extension 342, and then rotate the housing 211 to cover the base 1 (i.e. Figure 1 and Figure 4 status shown).

[0063] 4. Pull the extension part 342 of the pull-out strip 34 by hand. Since one end of the pull-out strip 34 is fixedly connected to one end of the lower protective film 33, the lower protective film 33 can be separated from the protective film body 32 by pulling the pull-out strip 34. By pulling the pull-out strip 34, the pull-out strip 34 and the lower protective film 33 are completely pulled out of the film sticking device.

[0064] 5. The user holds the hand buckle 18 on the base 1 with one hand to keep the base 1 fixed, and places the other hand in the hand buckle groove 210 and pulls the shell 211 to move the rolling assembly 2 toward the side close to the second positioning platform 14. At this time, the roller 22 moves while rolling the protective film body 32, so as to squeeze the protective film body 32 and attach it to the product to be pasted.

[0065] 6. After the rolling is completed, the rolling assembly 2 is reset (i.e., the rolling assembly 2 is slid to the end of the base 1 close to the first positioning platform 13), and then the shell 211 is rotated to open. The user pinches the lug 313 with his hand to tear off the upper protective film 31 from the protective film body 32, and then takes the product with the film attached out of the positioning groove 10, and the film application operation is completed.

[0066] The film sticking assembly provided by the embodiment of the utility model is provided with a limiting portion 162 on the positioning portion 161 of the first positioning structure 16. When the first end of the protective film 3 is sleeved on the first positioning structure 16, the first end of the protective film 3 can be clamped by the limiting portion 162 to fix the first end of the protective film 3 to the first positioning structure 16, that is, the protective film 3 can be pre-fixed in the film sticking device. On the one hand, the user does not need to install the protective film 3 in the film sticking device by himself when sticking the film, which saves the user's operating steps and facilitates the film sticking operation. At the same time, the protective film 3 is pre-installed in the film sticking device, and the protective film 3 does not need to be packaged separately, which can save packaging costs.

[0067] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
