[0046] First embodiment

[0047] like Figures 1 to 8As shown, the film pasting device provided by the first embodiment of the utility model 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 on 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 are enclosed to form a positioning groove 10 for placing the product to be pasted (the product to be pasted can be a mobile phone, a tablet, etc.). The first positioning platform 13 is provided with a first positioning structure 17, and the second positioning platform 14 is provided with a second positioning structure 18. The first positioning structure 17 and the second positioning structure 18 are respectively convexly arranged on the first positioning platform 13 and the second positioning platform 14. The first positioning structure 17 and the second positioning structure 18 cooperate with each other to position the protective film, thereby realizing the positioning between the protective film and the product to be pasted.

[0048] The rolling assembly 2 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 that match the slide rails 15 are provided on opposite sides of the rolling assembly 2 (the sliding parts 23 can be provided on the base 21 and / or the roller 22), 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. When the sliding part 23 slides to one end of the slide rail 15 close to the first positioning platform 13, the sliding part 23 can rotate relative to the base 1 (such as Figure 4a As shown, the sliding portion 23 is in a rotating state), that is, at this time the base 21 can rotate relative to the base 1.

[0049] The film pasting device provided in this embodiment is provided with a base 1 and a rolling assembly 2. When in use, the product to be pasted is first placed in the positioning groove 10 for positioning, and then the protective film is placed above the product to be pasted, and the two ends of the protective film are positioned by the first positioning structure 17 and the second positioning structure 18 respectively, so as to achieve the positioning between the product to be pasted and the protective film, and then the base 21 is pulled to make the roller 22 move while rolling the protective film, so as to squeeze and adhere the protective film to the product to be pasted. The film pasting device is not only convenient for film pasting operations, but also, because when the sliding part 23 slides to the end of the slide rail 15 close to the first positioning platform 13, the base 21 can rotate relative to the base 1, so that the base 21 can be rotated and uncovered before placing the protective film (such as Figures 9 to 12As shown, especially when the base 21 is a shell with a larger size), it is convenient to place the product to be filmed in the positioning groove 10 and to place the protective film on the product to be filmed (that is, after the base 21 is rotated, the positioning groove 10 and the positioning structure 17 / 18 on the base 1 are exposed); at the same time, in some embodiments, the sliding part 23 can also move downward after rotating relative to the base 1, so that the roller 22 can move downward and be stored on the side of the first positioning platform 13 away from the positioning groove 10 (such as Figure 2 As shown, that is, it is stored at the end of the base 1), so that the base 21 can also move downward a certain distance along with the roller 22, thereby reducing the height of the rolling assembly 2 when stored, thereby reducing the overall height (thickness) of the film-laminating device. When the film-laminating device is packaged in a packaging box, the thickness and volume of the packaging box can be reduced, thereby reducing the packaging cost and transportation cost.

[0050] like Figures 2 to 6 As shown, as an embodiment, the slide rail 15 includes a first rail 151 extending horizontally, the first rail 151 is arranged corresponding to the positioning groove 10 (that is, the first rail 151 is located on one side of the positioning groove 10), and the opposite ends of the first rail 151 correspond to the first positioning platform 13 and the second positioning platform 14 respectively (in this embodiment, the end of the first rail 151 does not exceed the first positioning platform 13; of course, the end of the first rail 151 can also exceed the first positioning platform 13). The slide rail 15 also includes a second rail 152, the second rail 152 is arranged corresponding to the first positioning platform 13 (that is, the second rail 152 is located on one side of the first positioning platform 13), the second rail 152 is connected to the first rail 151, and the sliding part 23 can slide horizontally along the first rail 151 and the second rail 152. When the sliding part 23 slides onto the second rail 152, the base 21 can rotate relative to the base 1.

[0051] like Figures 2 to 6As shown, as an embodiment, one end of the second track 152 is connected to the first track 151, and the other end of the second track 152 extends downward (specifically, it can extend vertically downward or extend obliquely downward). When the sliding part 23 slides onto the second track 152, the sliding part 23 can slide downward along the second track 152, that is, at this time, the sliding part 23 can rotate relative to the base 1 at the second track 152, so that the roller 22 can move downward after passing over the first positioning platform 13 and be stored on the side of the first positioning platform 13 away from the positioning groove 10. Of course, in other embodiments, the second track 152 may not be provided, for example, a notch is directly provided at the end of the first track 151 (not shown), and when the roller 22 passes over the first positioning platform 13, the sliding part 23 can be separated from the first track 151 and move downward at the position of the notch, so that the roller 22 and the base 21 can move downward; or no other track is provided at the end of the first track 151, and the sliding part 23 can directly move downward after being separated from the end of the first track 151.

[0052] After the roller 22 passes over the first positioning platform 13, the roller 22 can move downward and be stored on the side of the first positioning platform 13 away from the positioning groove 10 (such as Figure 2 As shown, that is, it is stored at the end of the base 1), so that the base 21 can also move downward a certain distance along with the roller 22, thereby reducing the height of the rolling assembly 2 when stored, thereby reducing the overall height (thickness) of the film-laminating device. When the film-laminating device is packaged in a packaging box, the thickness and volume of the packaging box can be reduced, thereby reducing the packaging cost and transportation cost.

[0053] like Figure 3a and Figure 7 As shown, as an embodiment, the second track 152 includes a horizontal section 152a extending horizontally and a vertical section 152b extending vertically (the vertical section 152b may extend straight downward or obliquely downward), the horizontal section 152a is located on one side of the first positioning platform 13, and the vertical section 152b is located on the side of the horizontal section 152a away from the first track 151. One end of the horizontal section 152a is connected to the first track 151, and the other end of the horizontal section 152a is connected to the vertical section 152b, and the connection position between the horizontal section 152a and the vertical section 152b is a smooth transition (the smooth structure can facilitate the sliding part 23 to slide from the horizontal section 152a to the vertical section 152b). As a result, the sliding part 23 can slide along the horizontal section 152a to the vertical section 152b, and slide downward along the vertical section 152b, that is, at this time, the sliding part 23 can rotate relative to the base 1, thereby causing the roller 22 and the base 21 to move downward. As shown Fig.14As shown, as another embodiment, the second track 152 is an arc-shaped structure extending obliquely downward. Of course, in other embodiments, the second track 152 can also be other shapes, such as a slope structure extending obliquely downward.

[0054] like Figure 7 As shown, as an implementation mode, the first rail 151 and the horizontal section 152 a are both disposed at the top edge of the side panel 12 , and the vertical section 152 b is disposed at the front end side edge of the side panel 12 .

[0055] like Figures 3a to 5 and Figure 8 As shown, as an embodiment, the sliding parts 23 are disposed on opposite sides of the base 21. The slide rail 15 is an outer rail, the slide rail 15 protrudes outward compared to the side plate 12, and the width of the second rail 152 protruding outward is smaller than the width of the first rail 151 protruding outward;

[0056] The sliding part 23 includes a vertically arranged support arm 231, a top arm 232 connected between the support arm 231 and the base 21, and a limiting part 233 arranged on the inner side wall of the support arm 231. The top arm 232 and the limiting part 233 are arranged opposite to each other at an upper and lower interval, and the top arm 232 is located above the limiting part 233; the slide rail 15 is located between the support arm 231, the top arm 232 and the limiting part 233, and the top wall, the outer side wall and the bottom wall of the first track 151 can respectively abut against the top arm 232, the support arm 231 and the limiting part 233, so that the first track 151 can be stably connected to the sliding part 23, ensuring the stability of the sliding part 23 when sliding, and then ensuring the film sticking effect;

[0057] The limiting portion 233 includes a limiting protrusion 2331 and a horizontally extending limiting convex strip 2332. The limiting convex strip 2332 is a long strip structure, and the inwardly protruding width of the limiting convex strip 2332 is smaller than the inwardly protruding width of the limiting protrusion 2331. Figure 4b As shown, when the sliding part 23 slides onto the second track 152, the limiting protrusion 2332 does not abut against the bottom wall of the second track 152, while the limiting protrusion 2331 can continue to abut against the bottom wall of the second track 152, so that the sliding part 23 will not be separated from the second track 152 and can continue to slide along the second track 152. As an embodiment, the limiting protrusion 2331 is arranged at the middle position of the limiting protrusion 2332; of course, the limiting protrusion 2331 can also be arranged at other positions.

[0058] Specifically, Figure 3b and Figure 8As shown, in order to ensure the film sticking effect, when the limiting portion 233 slides on the first track 151, it is necessary to ensure the stability of the sliding seat 211 to ensure the fit between the roller 22 and the protective film (the sliding seat 211 cannot rotate, otherwise it will affect the height of the roller 22, and then cause the roller 22 to separate from the protective film). Therefore, a long strip of limiting convex strip 2332 is set for limiting to ensure that the sliding seat 211 does not rotate. However, after the sliding portion 23 slides onto the second track 152, if the limiting convex strip 2332 does not disengage from the second track 152 (i.e., the limiting convex strip 2332 can interfere with the second track 152), the sliding portion 23 and the sliding seat 211 cannot continue to slide. Therefore, in this embodiment, the limiting portion 233 is configured to have a structure in which the limiting protrusion 2331 and the limiting convex strip 2332 cooperate. Since the inwardly protruding width of the limiting convex strip 2332 is smaller than the inwardly protruding width of the limiting protrusion 2331 (i.e., the limiting protrusion 2331 protrudes more inwardly than the limiting protrusion 2332), as shown in FIG. Figure 4b and Figure 8 As shown, after the sliding part 23 slides onto the second track 152, the limiting convex strip 2332 does not interfere with the second track 152, and the limiting protrusion 2331 can continue to abut against the bottom wall of the second track 152, so the sliding part 23 can continue to slide along the second track 152, and the limiting protrusion 2331 is a columnar or dot-shaped structure, so that the sliding part 23 can turn along the second track 152. At the same time, in order to facilitate the turning of the sliding part 23, the surface of the limiting protrusion 2331 used to contact the second track 152 is an arc-shaped structure, so that the limiting protrusion 2331 can smoothly pass through the connection position of the horizontal section 152a and the vertical section 152b (that is, the sliding part 23 is easier to rotate).

[0059] like Figure 3b and Figure 8 As shown, as an embodiment, the sliding part 23 also includes a stop arm 234 arranged vertically, the stop arm 234 is connected to the top arm 232, and the stop arm 234 is arranged opposite to the support arm 231 at intervals, and the inner side wall of the first track 151 can abut against the stop arm 234. Therefore, under the joint action of the support arm 231, the top arm 232, the limit part 233 and the stop arm 234, the first track 151 can be limited in both the up and down directions and the left and right directions, thereby improving the stability during sliding. At the same time, the stop arm 234 can also abut against the top surface of the side plate 12, thereby further improving the stability during sliding. Specifically, the support arm 231, the top arm 232, the limit part 233 and the stop arm 234 enclose a sliding groove 230, and the slide rail 15 is located in the sliding groove 230.

[0060] like Figure 2 and Figure 8As shown, as an embodiment, the base 21 includes a sliding seat 211 and a pulling portion 210, the roller 22 is rotatably connected to the sliding seat 211, the sliding portion 23 is disposed on opposite sides of the sliding seat 211, and the pulling portion 210 is rotatably connected to the sliding seat 211; the sliding seat 211 is relatively small in size, and the sliding seat 211 can be stored together with the roller 22 on the side of the first positioning platform 13 away from the positioning groove 10. At the same time, since the pulling portion 210 is rotatably connected to the sliding seat 211, when stored, the pulling portion 210 can be bent and erected above the base 1.

[0061] like Figure 6 As shown, as an embodiment, a stop portion 131 is provided on the side of the first positioning platform 13 away from the positioning groove 10; when the sliding seat 211 slides to the side of the first positioning platform 13 away from the positioning groove 10, the sliding seat 211 can abut against the stop portion 131, thereby preventing the sliding seat 211 from falling off.

[0062] like Figure 2 and Figure 8 As shown in the figure, as an embodiment, the pulling part 210 is a handle 212, which is relatively small in size and is used for the user to pull it by hand, thereby driving the sliding seat 211 and the roller 22 to move. At the same time, the handle 212 is also provided with a first hand hole 212a, which can be passed through by the user's finger, thereby facilitating the pulling of the handle 212.

[0063] like Figure 1 and Figure 2 As shown, as an embodiment, the film sticking device further includes a first shell 3 that can cover the base 1. The first shell 3 can cover the entire base 1 and the rolling assembly 2, thereby improving the aesthetics of the device. At the same time, a avoidance groove 31 is provided on the first shell 3 at a position corresponding to the handle 212; when the base 1 and the rolling assembly 2 are covered by the first shell 3, the handle 212 can also be exposed through the avoidance groove 31 on the first shell 3, so that the user can pull the handle 212 to perform the film sticking operation. Of course, in other embodiments, the first shell 3 may not be provided.

[0064] like Figure 5 As shown, as an embodiment, the first positioning structure 17 includes two first positioning posts 171 disposed at intervals and a support platform 172 located between the two first positioning posts 171, and the second positioning structure 18 includes two second positioning posts 181 disposed at intervals. One end of the protective film is provided with holes corresponding to the positions of the two first positioning posts 171, and the other end of the protective film is also provided with holes corresponding to the positions of the two second positioning posts 181.

[0065] When applying the film, first slide the rolling assembly 2 to the side of the first positioning structure 17 away from the positioning groove 10 (ie, Figure 4aThe product to be laminated is then placed in the positioning groove 10 for positioning, and the protective film is placed above the product to be laminated, and one end of the protective film is positioned by two first positioning columns 171 and supported by the support platform 172, and the other end of the protective film is positioned by two second positioning columns 181, thereby achieving positioning between the product to be laminated and the protective film. Then the handle 212 is pulled to move the rolling assembly 2 toward the side close to the second positioning platform 14, and at this time, the roller 22 rolls the protective film while moving, so that the protective film is squeezed and attached to the product to be laminated.

[0066] The film pasting device provided by the embodiment of the utility model is provided with a base 1 and a rolling assembly 2. When in use, the product to be pasted with film is first placed in the positioning groove 10 for positioning, and then the protective film is placed above the product to be pasted with film, and the two ends of the protective film are respectively positioned by the first positioning structure 17 and the second positioning structure 18, so as to achieve the positioning between the product to be pasted with film and the protective film, and then the base 21 is pulled to make the roller 22 move while rolling the protective film, so as to squeeze the protective film and adhere it to the product to be pasted with film. The film sticking device is not only convenient for film sticking operations, but also, because when the sliding part 23 slides to one end of the slide rail 15 close to the first positioning platform 13, the sliding part 23 can rotate relative to the base 1, thereby allowing the base 21 to rotate relative to the base 1, so that the base 21 can be rotated and uncovered before placing the protective film, which is convenient for placing the product to be filmed in the positioning groove 10 and placing the protective film above the product to be filmed; at the same time, the sliding part 23 can also move downward after rotating relative to the base 1, so that the roller 22 can move downward and be stored on the side of the first positioning platform 13 away from the positioning groove 10, so that the base 21 can also move downward with the roller 22 for a distance, thereby reducing the height of the rolling assembly 2 when stored, thereby reducing the overall height (thickness) of the film sticking device, and when the film sticking device is packaged in a packaging box, the thickness and volume of the packaging box can be reduced, thereby reducing the packaging cost and transportation cost.
