Technical Field
[0001] The utility model relates to the technical field of film sticking devices, in particular to a film sticking device. 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-attaching device is a new type of film-attaching device, which positions the product to be attached 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 of the product to be attached from one end to the other end in sequence, so that the protective film can be attached to the product to be attached accurately and efficiently.
[0003] However, when the current roller-type film-applying device is applying the film, film bubbles are easily generated at the end of the screen of the product to be applied. The main reasons are:
[0004] like Figure 1 As shown, the current roller-type film-laminating device generally includes a base 1 and a rolling assembly, and the rolling assembly includes a roller 22. Positioning posts 10 are provided at both ends of the base 1; 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 (not shown) and a pull-out strip (not shown) stacked in sequence from top to bottom. When laminating, first place the product 5 to be laminating in the base 1, and then hang the two ends of the upper protective film 31 on the positioning posts 10 at both ends of the base 1, so that the protective film 3 is suspended above the product 5 to be laminating, and there is a certain distance between the lower surface of the protective film 3 and the product 5 to be laminating (that is, the two are not in contact); then pull the pull-out strip to tear off the lower protective film from the protective film body 32, and the following is achieved. Figure 1 Then the roller 22 is driven to move from one end of the product 5 to be laminated to the other end. During the movement, the roller 22 rolls the upper protective film 31 and the protective film body 32, so that the protective film body 32 is sequentially attached to the screen of the product 5 to be laminated, and the protective film body 32 is gradually separated from the upper protective film 31.
[0005] When the roller 22 gradually moves to the end of the product 5 to be filmed, most of the protective film body 32 has been separated from the upper protective film 31, that is, the bonding area between the protective film body 32 and the upper protective film 31 is very small, and the connection force between the two is very weak, so that before the roller 22 rolls to the end of the product 5 to be filmed, the end of the protective film body 32 has fallen to the surface of the product 5 to be filmed under the action of its own gravity. This process can easily form bubbles between the end of the protective film body 32 and the product 5 to be filmed (even after subsequent rolling by the roller 22, the bubbles cannot be effectively eliminated), thereby generating film bubbles at the end of the screen of the product 5 to be filmed (especially when the protective film body 32 is a curved film).
[0006] In view of this, it is necessary to design a film sticking device that can avoid the generation of film sticking bubbles. Utility Model Content

[0042] 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.
[0043] like Figures 2 to 11cAs shown, the film pasting device provided by the embodiment of the utility model includes a base 1, a rolling assembly 2 and a tail buckle 4. 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. 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 enclose a positioning groove 10 for placing the product 5 to be pasted with a film (the product 5 to be pasted with a film can be a mobile phone, a tablet, etc.). A first positioning structure 16 is provided on the first positioning platform 13, and a second positioning structure 17 is provided on the second positioning platform 14. 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 first positioning structure 16 and the second positioning structure 17 are respectively used to position and connect with the opposite ends of the protective film 3, that is, one end of the protective film 3 is hung on the first positioning structure 16, and the other end of the protective film 3 is hung on the second positioning structure 17, so as to position the protective film 3 and further realize the positioning between the protective film 3 and the product 5 to be pasted.
[0044] 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.
[0045] The tail buckle 4 is located at one end of the base 1 close to the second positioning platform 14, and the tail buckle 4 includes a support portion 41. When the film is applied, at least part of the support portion 41 is located between the product 5 to be applied and the protective film 3. The support portion 41 is used to lift the end of the protective film 3 close to the second positioning platform 14 upward (that is, the support portion 41 supports the end of the protective film 3. Specifically, the support portion 41 lifts the end of the protective film body 32 in the protective film 3 upward). After the support portion 41 contacts the roller 22, it can move toward the side away from the first positioning platform 13 under the squeezing action of the roller 22. It should be noted that the support portion 41 may be in contact with the end of the protective film 3 and lift the end of the protective film 3 upward before the roller 22 moves to the end of the base 1 close to the second positioning platform 14; or the support portion 41 and the end of the protective film 3 may be spaced a certain distance apart from each other up and down before the roller 22 moves to the end of the base 1 close to the second positioning platform 14, and when the roller 22 moves to the end of the base 1 close to the second positioning platform 14, the roller 22 squeezes the end of the protective film 3 downward, and only then does the support portion 41 contact with the end of the protective film 3 and lift the end of the protective film 3 upward (i.e., Fig.11a and Fig.11b shown).
[0046] The film pasting device provided by the embodiment of the utility model is provided with a tail buckle 4. When pasting the film, the support portion 41 of the tail buckle 4 can lift the end of the protective film 3 close to the second positioning platform 14 upward, and when the roller 22 moves to the end of the base 1 close to the second positioning platform 14, after the roller 22 contacts the support portion 41, the support portion 41 can move toward the side away from the first positioning platform 13 under the squeezing and pushing action of the roller 22, that is, when the roller 22 has not yet contacted the support portion 41, the protective film 3 is close to the second positioning platform 14. One end of the positioning platform 14 will be lifted upward by the support part 41, and will not fall to the surface of the product 5 to be filmed in advance under the action of its own gravity. When the roller 22 contacts the support part 41, it will push the support part 41, so that the end of the protective film 3 close to the second positioning platform 14 falls from the support part 41 and adheres to the surface of the product 5 to be filmed. At the same time, the roller 22 rolls the end of the protective film 3 to squeeze out the gas at the end of the protective film 3 to avoid bubbles between the end of the protective film 3 and the surface of the product 5 to be filmed. The film-pasting device can avoid film-pasting bubbles at the end of the screen of the product 5 to be filmed, facilitate film-pasting operations, and improve the user experience.
[0047] like Figures 3 to 5 and Figures 11a to 11cAs shown, as an embodiment, the tail buckle 4 also includes a mounting seat 42 connected to the support portion 41, the mounting seat 42 and the support portion 41 are an integral structure, the mounting seat 42 is rotatably connected to the end of the base 1 close to the second positioning platform 14, and the support portion 41 extends and protrudes from the mounting seat 42 toward the side close to the first positioning platform 13. When the support portion 41 contacts the roller 22, the tail buckle 4 can rotate toward the side away from the first positioning platform 13 under the squeezing action of the roller 22, so that the end of the protective film 3 close to the second positioning platform 14 falls from the support portion 41 and adheres to the surface of the product 5 to be filmed. As an embodiment, the support portion 41 can be made of elastic material or non-elastic material (that is, the support portion 41 can be elastic or not), and can be made of plastic material.
[0048] like Figures 3 to 5 As shown, as an embodiment, the second positioning platform 14 includes two bosses 141, and the two bosses 141 are spaced apart along the width direction of the base 1 (the base 1 is a square structure, and the base 1 has a length direction and a width direction), and the second positioning structure 17 is arranged on the two bosses 141. At the same time, a rear side plate 142 is connected between the two bosses 141. The mounting seat 42 is arranged between the two bosses 141, and the opposite sides of the mounting seat 42 are respectively rotatably connected to the two bosses 141. Specifically, in this embodiment, the opposite sides of the mounting seat 42 are provided with a rotating shaft 421, and the two bosses 141 are provided with a rotating hole 141A, and the rotating shafts 421 on the opposite sides are respectively inserted into the rotating holes 141A of the two bosses 141 to realize the rotatable connection between the mounting seat 42 and the boss 141.
[0049] like Figures 3 to 5 and Figures 11a to 11c As shown, as an embodiment, an elastic part 19 is provided on one end of the base 1 close to the second positioning platform 14, and the elastic part 19 contacts the tail buckle 4 (specifically contacts the mounting seat 42); the elastic part 19 is used to drive the tail buckle 4 to rotate and reset toward the side close to the first positioning platform 13 by elastic force. That is, when the tail buckle 4 rotates toward the side away from the first positioning platform 13 under the squeezing action of the roller 22, the elastic part 19 can be elastically deformed and accumulate force; when the tail buckle 4 loses the squeezing action of the roller 22, the tail buckle 4 can rotate and reset toward the side close to the first positioning platform 13 under the elastic force of the elastic part 19.
[0050] like Figure 3 and Figure 4As shown, as an embodiment, a avoidance hole 111 is provided on the bottom plate 11, and the elastic part 19 is an elastic plate arranged in the avoidance hole 111, one side of the elastic plate is connected to the base 1, and the other side of the elastic plate is in contact with the tail buckle 4; the elastic plate is in a suspended state, so that the elastic plate has elasticity (specifically, in this embodiment, one side of the elastic plate is connected to the rear side plate 142. Of course, in other embodiments, one side of the elastic plate can also be connected to the bottom plate 11). In other embodiments, the elastic part 19 can also be an elastic member (such as a spring), and the two ends of the elastic member are respectively in contact with the tail buckle 4 and the base 1 (specifically, it can be the rear side plate 142 on the base 1), and the elastic member can store force when the tail buckle 4 rotates toward the side away from the first positioning platform 13, thereby providing a restoring force for the tail buckle 4.
[0051] like Figures 3 to 5 and Figures 11a to 11c As shown, as an embodiment, the support portion 41 is L-shaped, and the support portion 41 includes a first bending portion 41A and a second bending portion 41B connected to each other, the second bending portion 41B is vertically arranged, and the first bending portion 41A is horizontally extended; the bottom end of the second bending portion 41B is connected to the mounting seat 42, one end of the first bending portion 41A is connected to the top end of the second bending portion 41B, and the other end of the first bending portion 41A extends and protrudes toward the side close to the first positioning platform 13.
[0052] like Figures 3 to 5 and Figures 11a to 11c As shown, as an embodiment, a slope 411 for contacting the protective film 3 is provided on one side of the support portion 41 close to the first positioning platform 13 (specifically, the slope 411 is provided on the end of the first bending portion 41A away from the mounting seat 42). By providing the slope 411, not only can the roller 22 more easily push the support portion 41 after contacting the support portion 41 (the roller 22 will contact the slope 411), but also the end of the protective film 3 can more easily detach from the support portion 41 along the slope 411 (the end of the protective film 3 rests on the slope 411).
[0053] like Fig.12 As shown, as another embodiment, the support portion 41 is made of an elastic material, and the support portion 41 has a certain elasticity. The support portion 41 can be specifically made of a plastic material; of course, the support portion 41 can also be made of an elastic metal material (such as steel, iron, etc.), silicone, or other materials. After the support portion 41 contacts the roller 22, it can be elastically deformed toward the side away from the first positioning platform 13 under the squeezing action of the roller 22; and the support portion 41 can return to its state before deformation after losing the squeezing action of the roller 22. The tail buckle 4 also includes a mounting seat 42 connected to the support portion 41, and the mounting seat 42 is fixedly connected to one end of the base 1 close to the second positioning platform 14. Specifically, refer to Figure 4 and Fig.12 The second positioning platform 14 includes two bosses 141, which are spaced apart along the width direction of the base 1, and the mounting seat 42 is disposed between the two bosses 141. The mounting seat 42 can be fixedly connected to the bottom plate 11, the bosses 141 or the rear side plate 142 (in this embodiment, the mounting seat 42 is a plate-like structure, and a screw hole is provided on the mounting seat 42, and the mounting seat 42 can be screwed and fixed to the bottom plate 11 by screws).
[0054] like Fig.13 As shown, as another embodiment, the tail buckle 4 and Fig.12 The tail buckle 4 shown is substantially the same, and the support portion 41 is also made of an elastic material. The difference is that the tail buckle 4 also includes an elastic arm 43, which also has a certain elasticity (the elastic arm 43 and the support portion 41 are made of the same material), and the elastic arm 43 is connected between the mounting seat 42 and the support portion 41. When the support portion 41 is in contact with the roller 22 and is squeezed by the roller 22, the elastic arm 43 can also undergo elastic deformation, thereby making it easier for the tail buckle 4 to undergo elastic deformation. The mounting seat 42 is a U-shaped structure, and the two sides of the support portion 41 are connected to the two sides of the mounting seat 42 through the elastic arms 43. Reference Figure 4 and Fig.13 The mounting seat 42 is clamped between the two bosses 141 (the shape and size of the mounting seat 42 match the shape and size of the accommodating space between the two bosses 141). At the same time, the mounting seat 42 also abuts against the rear side plate 142 to limit and fix the mounting seat 42.
[0055] like Fig.14 and Fig.15 As shown, as another embodiment, the tail buckle 4 and Fig.12 The tail buckle 4 shown is substantially the same, and the support portion 41 is also made of elastic material, and the support portion 41 has a certain elasticity. The support portion 41 can be specifically made of plastic material; of course, the support portion 41 can also be made of elastic metal material (such as steel, iron, etc.), silicone and other materials. After the support portion 41 contacts the roller 22, it can be elastically deformed toward the side away from the first positioning platform 13 under the squeezing action of the roller 22; and the support portion 41 can return to the state before deformation after losing the squeezing action of the roller 22. Fig.12The tail buckle 4 shown is different in that the tail buckle 4 is used to be plugged and installed on the charging port (not shown) of the product 5 to be filmed. Specifically, the tail buckle 4 also includes a charging port plug-in portion 44 connected to the support portion 41, and the charging port plug-in portion 44 and the support portion 41 extend and protrude in substantially the same direction. The charging port plug-in portion 44 is used to be plugged and fixed with the charging port on the product 5 to be filmed, so as to install the tail buckle 4 on the product 5 to be filmed (when the product 5 to be filmed is placed in the positioning groove 10, the charging port of the product 5 to be filmed is located at one end of the base 1 close to the second positioning platform 14). The tail buckle 4 also includes a handle 45 connected to the charging port plug-in portion 44, and the handle 45 and the charging port plug-in portion 44 extend in opposite directions respectively; when in use, the user pinches the handle 45 with his hand, and then plugs the charging port plug-in portion 44 into the charging port on the product 5 to be filmed for easy operation.
[0056] Specifically, Fig.14 and Fig.15 As shown, the cross section of the charging port inserting portion 44 is an inverted U-shaped structure (of course, the cross section of the charging port inserting portion 44 can also be a U-shaped structure or other shapes), which can be plugged and fixed with the type-c charging port on the product to be filmed 5. Since the cross section of the charging port inserting portion 44 is a semi-annular structure (that is, it is not a complete annular structure), the charging port inserting portion 44 and the charging port on the product to be filmed 5 will not be inserted too tightly. When the support portion 41 is squeezed by the roller 22, the tail buckle 4 can be withdrawn from the charging port on the product to be filmed 5 as a whole and move backward, so that the end of the protective film 3 can be more easily separated from the support portion 41.
[0057] like Fig.14 and Fig.15 As shown, the tail buckle 4 also includes a connection seat 46, and the support portion 41, the charging port insertion portion 44 and the handle 45 are all connected to the connection seat 46. The support portion 41 is an L-shaped structure, and the support portion 41 includes a first bending portion 41A and a second bending portion 41B connected to each other, the second bending portion 41B is vertically arranged, and the first bending portion 41A is horizontally extended; the bottom end of the second bending portion 41B is connected to the connection seat 46, one end of the first bending portion 41A is connected to the top of the second bending portion 41B, and the other end of the first bending portion 41A extends toward the side close to the first positioning platform 13 (reference Figure 4 ). The charging port inserting portion 44 extends in the same direction as the first bent portion 41A, and the handle 45 extends in the opposite direction to the first bent portion 41A. When the charging port inserting portion 44 is inserted into the charging port of the product 5 to be filmed, the connecting seat 46 can abut against the side wall of the product 5 to be filmed, thereby limiting the insertion depth of the charging port inserting portion 44. At the same time, refer to Figure 4 and Fig.14When the tail buckle 4 is installed on the product 5 to be film-coated, the handle 45 is located in the accommodation space between the two bosses 141, thereby avoiding interference between the handle 45 and the base 1.
[0058] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, as an embodiment, the base 21 is a shell 211, the shell 211 can cover the base 1, and the roller 22 is rotatably connected to the shell 211; the roller 22 is arranged below the shell 211, and the opposite ends of the roller 22 are provided with a rotating shaft 221, and the rotating shafts 221 at the opposite ends are respectively rotatably connected to the opposite sides of the shell 211, so that the roller 22 can rotate relative to the shell 211. 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.

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.
[0062] 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 5 to be applied with the film.
[0063] like Figures 8 to 10 As shown in the figure, as an embodiment, the protective film 3 includes an upper protective film 31 (i.e., 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 used to be finally attached to the product 5 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 5 to be attached. The pull-out strip 34 is used to tear the lower protective film 33 from the protective film body 32 by pulling the pull-out strip 34 during the film attachment process.
[0064] The length of the pull-out strip 34 is greater than the length of the lower protective film 33, and one end of the pull-out strip 34 close to the first positioning platform 13 is fixedly connected to one end of the lower protective film 33 close to the first positioning platform 13 (the pull-out strip 34 and the lower protective film 33 can be fixed by adhesive bonding. Specifically, an end of the lower protective film 33 close to the first positioning platform 13 is provided with an outer protrusion 331, and one end of the pull-out strip 34 is adhesively fixed to the outer protrusion 331), and one end of the pull-out strip 34 close to the second positioning platform 14 extends to one side of the lower protective film 33. The length and width of the lower protective film 33 are the same or similar to those of the protective film body 32. The length of the upper protective film 31 is greater than the length of the protective film body 32, and the two ends of the upper protective film 31 along its length direction extend to the two sides of the protective film body 32 respectively. The upper protective film 31 has a first positioning hole 311 and a second positioning hole 312 at opposite ends thereof. The first positioning structure 16 is sleeved in the first positioning hole 311 , and the second positioning structure 17 is sleeved in the second positioning hole 312 , thereby realizing the positioning connection between the protective film 3 and the base 1 .
[0065] like Figures 8 to 10 As shown, as an embodiment, a lug 313 is provided on one end of the upper protective film 31 close to the second positioning platform 14, and the lug 313 extends to one side of the protective film body 32; after the film is applied, the user pinches the lug 313 with his hands to peel off the upper protective film 31 or remove it from the base 1.
[0066] As an implementation method, the method for using the film sticking device is as follows:
[0067] 1. When performing the film laminating operation, first slide the roller 22 to the side of the first positioning platform 13 away from the positioning groove 10 (i.e. Fig.11a The protective film 3 is then hung above the product 5 to be pasted with film, and the lower surface of the protective film 3 is spaced a certain distance from the product 5 to be pasted with film; the shell 211 is then rotated to cover the base 1.
[0068] 2. Pull the end of the pull-out strip 34 by hand (such as Fig.10 As shown, the end of the pull-out strip 34 extends out of the base 1). 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; Fig.11a As shown, at this time, only the protective film body 32 and the upper protective film 31 remain on the protective film 3 above the product 5 to be laminated.
[0069] 3. 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 and the upper protective film 31, so that the protective film body 32 is attached to the screen of the product 5 to be filmed in turn, and the protective film body 32 is gradually separated from the upper protective film 31.
[0070] like Fig.11b As shown, when the roller 22 moves to the end of the base 1 close to the second positioning platform 14, the roller 22 squeezes the end of the protective film body 32 downward, and the end of the protective film body 32 is separated from the upper protective film 31 and rests on the support portion 41 of the tail buckle 4; Fig.11c As shown, when the roller 22 continues to move toward the side close to the second positioning platform 14, the tail buckle 4 rotates under the squeezing action of the roller 22, so that the end of the protective film body 32 is detached from the support portion 41 and adhered to the surface of the product 5 to be filmed, and at the same time, the roller 22 rolls the end of the protective film body 32 to squeeze out the gas at the end of the protective film body 32 to avoid the formation of bubbles between the end of the protective film body 32 and the surface of the product 5 to be filmed (moreover, even if bubbles are generated between the end of the protective film body 32 and the product 5 to be filmed, after the filming operation is completed, the tail buckle 4 can be used to rotate in the opposite direction to peel off the end of the protective film body 32 from the product 5 to be filmed, and the end of the protective film body 32 can be rolled again; that is, at this time, the tail buckle 4 acts as a shovel, which can peel off the end of the protective film body 32).
[0071] 4. After the rolling is completed, the rolling assembly 2 is reset (i.e., the roller 22 is slid to the side of the first positioning platform 13 away from the positioning groove 10), and then the shell 211 is rotated to open. The user pinches the lug 313 with his hand, peels off the upper protective film 31 or removes it from the base 1, and then takes the product with the film attached out of the positioning groove 10, and the film application operation is completed.
[0072] The film pasting device provided by the embodiment of the utility model is provided with a tail buckle 4. When pasting the film, the support portion 41 of the tail buckle 4 can lift the end of the protective film 3 close to the second positioning platform 14 upward, and when the roller 22 moves to the end of the base 1 close to the second positioning platform 14, after the roller 22 contacts the support portion 41, the support portion 41 can move toward the side away from the first positioning platform 13 under the squeezing and pushing action of the roller 22, that is, when the roller 22 has not yet contacted the support portion 41, the protective film 3 is close to the second positioning platform 14. One end of the positioning platform 14 will be lifted upward by the support part 41, and will not fall to the surface of the product 5 to be filmed in advance under the action of its own gravity. When the roller 22 contacts the support part 41, it will push the support part 41, so that the end of the protective film 3 close to the second positioning platform 14 falls from the support part 41 and adheres to the surface of the product 5 to be filmed. At the same time, the roller 22 rolls the end of the protective film 3 to squeeze out the gas at the end of the protective film 3 to avoid bubbles between the end of the protective film 3 and the surface of the product 5 to be filmed. The film-pasting device can avoid film-pasting bubbles at the end of the screen of the product 5 to be filmed, facilitate film-pasting operations, and improve the user experience.
