Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, and in particular to a film scraping assembly and a film applicator. Background Technology

[0002] The film applicator includes a mounting base and a film scraping assembly. The mounting base is used to accommodate the mobile terminal. The film scraping assembly includes a sliding base and a film scraping block. The sliding base is slidably mounted on the mounting base. The bottom of the sliding base has a mounting groove that matches the size of the film scraping block. Part of the film scraping block is mounted in the mounting groove, and the other part protrudes from the mounting groove to apply pressure to the film.

[0003] Because both excessively long and excessively short squeegee blocks will leave a lot of air bubbles after squeegeeing, the length of the squeegee block needs to be adapted to the width of the mobile terminal. Since different models of mobile terminals have different widths, different models of mobile terminals need to be used with squeegee blocks of different lengths. Furthermore, since the size of the mounting groove on the sliding base needs to be adapted to the squeegee block, corresponding sliding bases need to be customized for different models of mobile terminals, resulting in extremely high mold opening costs. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a film scraping assembly to solve the problem of extremely high mold opening costs in the prior art for customizing corresponding sliding seats for mobile terminals with different waist sizes.

[0005] In a first aspect, this utility model provides a film scraping assembly, including: a sliding seat and a film scraping block. The bottom of the sliding seat is provided with an installation groove adapted to the size of the film scraping block. The film scraping block is installed in the installation groove. The film scraping block includes a film scraping surface, a front end surface, and a rear end surface. The film scraping surface is located outside the installation groove and is disposed opposite to the bottom of the installation groove. The front end surface and the rear end surface are both adjacent to the film scraping surface and are disposed opposite to each other. The two sides of the film scraping surface are provided with a first notch connecting the front end surface and the rear end surface.

[0006] Optionally, it also includes an adhesive layer located between the wall of the mounting groove and the scraper block for fixing the scraper block.

[0007] Optionally, the adhesive layer includes a first adhesive area and a second adhesive area, which are respectively disposed on both sides of the mounting groove.

[0008] Secondly, this utility model embodiment also provides a film applicator, which includes a mounting base and a film scraping assembly shown in the first aspect above. The mounting base is provided with a receiving groove for accommodating a mobile terminal. The film scraping assembly is the film scraping assembly shown above, and the sliding seat of the film scraping assembly is slidably disposed on the mounting base.

[0009] Optionally, it also includes a positioning block, which is installed in the receiving groove so that the receiving groove forms an installation space adapted to the mobile terminal.

[0010] Optionally, the bottom of the receiving groove is provided with a clearance opening for avoiding the camera module of the mobile terminal. The bottom of the mounting base is provided with two sets of support blocks, which are spaced apart in the width direction of the mounting base. Each set of support blocks includes a middle support block and two end support blocks. The two end support blocks are located on both sides of the middle support block in the length direction of the mounting base. The height of the middle support block is less than that of the two end support blocks.

[0011] Optionally, the mounting base further includes a first positioning structure and a slide rail. In the length direction of the mounting base, the first positioning structure is disposed on one side of the receiving groove, and the first positioning structure is used to position the film. The slide rail is disposed along the length direction of the mounting base. The sliding seat is slidably connected to the mounting base through the slide rail, and the sliding seat is rotatably connected to the mounting base, so that the sliding seat can rotate toward the receiving groove and cover the first positioning structure, and so that the sliding seat can rotate away from the receiving groove and expose the first positioning structure.

[0012] Optionally, the sliding seat is provided with a first rotating shaft, and the slide rail is a rib provided on the side wall of the mounting seat. The rib includes: a first extension section, which is provided along the length direction of the mounting seat, and the first rotating shaft is provided in the gravity direction of the first extension section; a bent section, one end of which is connected to the end of the first extension section near the first positioning structure, and the other end is bent and extended in the gravity direction; and a second extension section, which is connected to the other end of the bent section and extends in the direction near the receiving groove.

[0013] Optionally, the sliding seat is further provided with a rotation limiting block, which is spaced apart from the first rotating shaft and is also located in the gravity direction of the first extension section; the first extension section is provided with a first notch, and the length of the rotation limiting block is less than the depth of the first notch; when the sliding seat slides to cover the first positioning structure, the rotation limiting block is directly opposite the first notch.

[0014] Optionally, the slide rail is located at the top of the side wall of the mounting base, and the section of the slide rail near the first positioning structure is bent and extended in a direction away from gravity.

[0015] Compared with the prior art, the beneficial effects of the film scraping assembly provided in this embodiment of the present invention are as follows:

[0016] This utility model embodiment provides a film scraping assembly, which includes a sliding seat and a film scraping block. The bottom of the sliding seat is provided with an installation groove adapted to the size of the film scraping block. The film scraping block is installed in the installation groove and includes a film scraping surface, a front end surface, and a rear end surface. The film scraping surface is located outside the installation groove and is opposite to the bottom of the installation groove. The front end surface and the rear end surface are adjacent to the film scraping surface and are opposite to each other. Specifically, the two sides of the film scraping surface are provided with a first notch connecting the front end surface and the rear end surface. This first notch changes the length of the film scraping surface, so that the originally excessively long film scraping surface can be adapted to the width of the mobile terminal, avoiding poor film application. It is worth mentioning that although this first notch changes the length of the film scraping surface, it does not change the overall length of the film scraping block. Therefore, the size of the installation groove on the sliding seat does not need to be changed. It can be seen that by simply setting the corresponding first notch according to the width of the mobile terminal, the film scraping assembly can be adapted to mobile terminals of different widths without changing the size of the installation groove, which greatly reduces the mold opening cost of the sliding seat.

[0035] 300, Positioning Block. Detailed Implementation

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] This utility model embodiment provides a film scraping assembly 100, such as Figure 1 and Figure 2As shown, the film scraping assembly 100 includes a sliding seat 110 and a film scraping block 120. The bottom of the sliding seat 110 is provided with a mounting groove 111 that matches the size of the film scraping block 120. The film scraping block 120 is installed in the mounting groove 111. The film scraping block 120 includes a film scraping surface 121, a front end surface 122, and a rear end surface 123. The film scraping surface 121 is located outside the mounting groove 111 and is opposite to the bottom of the mounting groove 111. The front end surface 122 and the rear end surface 123 are both adjacent to the film scraping surface 121. The front end surface 122 and the rear end surface 123 are opposite to each other. The two sides of the film scraping surface 121 are provided with a first notch 124 that connects the front end surface 122 and the rear end surface 123.

[0038] Specifically, in this embodiment, the scraping block 120 has a first notch 124 on both sides of the scraping surface 121 that connects the front end surface 122 and the rear end surface 123. This first notch 124 changes the length of the scraping surface 121, so that the originally excessively long scraping surface 121 can be adapted to the width of the mobile terminal, thus avoiding poor film application.

[0039] It is worth mentioning that although the first notch 124 changes the length of the scraping surface 121, it does not change the overall length of the scraping block 120. Therefore, the size of the mounting groove 111 on the sliding seat 110 does not need to be changed. Thus, by simply setting the corresponding first notch 124 according to the width of the mobile terminal, the scraping assembly 100 can be adapted to mobile terminals of different widths without changing the size of the mounting groove 111. Since the size of the mounting groove 111 does not need to be changed, implementing this embodiment does not require customizing corresponding sliding seats 110 for different models of mobile terminals, greatly reducing the mold opening cost of the sliding seat 110.

[0040] In a specific embodiment, the scraping assembly 100 further includes an adhesive layer (not shown in the figure), which is located between the groove wall of the mounting groove 111 and the scraping block 120, and is used to fix the scraping block 120.

[0041] Specifically, the scraper block 120 can be installed in the mounting groove 111 by interference fit, but this installation is relatively loose, and applying external force to the scraper block 120 can cause the scraper block 120 to move relative to the mounting groove 111. In order to avoid unnecessary displacement of the scraper block 120, this embodiment uses an adhesive layer to fix the scraper block 120 to the groove wall of the mounting groove 111.

[0042] It is worth mentioning that although double-sided tape can be applied to the scraper block 120 to adhere it to the mounting groove 111, the tape is too sticky and easily sticks to other places or objects during actual operation, requiring high operational skill, making assembly difficult, and time-consuming. Therefore, this embodiment uses an adhesive layer to fix the scraper block 120, which reduces operational requirements and assembly difficulty. During assembly, the adhesive can be pre-applied to the scraper block 120 or the groove wall of the mounting groove 111, preferably to the groove wall of the mounting groove 111. This avoids the adhesive coming into contact with other objects or the assembler when operating the scraper block 120.

[0043] In a specific embodiment, the adhesive layer includes a first adhesive area (not shown in the figure) and a second adhesive area (not shown in the figure). The first adhesive area and the second adhesive area are respectively disposed on both sides of the mounting groove 111, so that the column scraper block 120 can be firmly fixed. In actual operation, only a small amount of adhesive needs to be applied to both sides of the mounting groove 111. Compared with applying an adhesive strip with a length almost the same as the mounting groove 111, the amount of adhesive used will be much less.

[0044] In some embodiments, the scraping block 120 is an EVA scraping block.

[0045] Specifically, EVA foam has a moderate softness and firmness and is elastic, which helps to ensure the film application effect. In addition, EVA foam can be repeatedly recycled and has little harm to the environment.

[0046] This utility model embodiment also provides a film applicator 1000, such as Figures 3-5 As shown, the film applicator 1000 includes a mounting base 200 and a film scraping assembly 100 as illustrated in the above embodiments. The mounting base 200 is provided with a receiving groove 210 for receiving a mobile terminal, and a sliding base 110 is slidably disposed on the mounting base 200.

[0047] The beneficial effects of this embodiment have been described in detail in the above-described embodiments of the film scraping assembly 100, so they will not be repeated here.

[0048] refer to Figure 3 and Figure 4 In a specific embodiment, the film applicator 1000 further includes a positioning block 300, which is installed in the receiving groove 210 so that an installation space 211 adapted to the mobile terminal is formed in the receiving groove 210.

[0049] Specifically, while the receiving slot 210 can be machined according to the shape of the mobile terminal, allowing it to be positioned and installed even without the positioning block 300, this requires producing a separate mounting base 200 for each mobile terminal, resulting in high mold costs and significant inventory buildup, thus leading to high production costs. To solve this technical problem, the receiving slot 210 can be made larger, allowing the installation of the positioning block 300 designed according to the mobile terminal's shape, creating an installation space within the receiving slot 210 that is compatible with the mobile terminal. With this design, the mounting base 200 can be applied to multiple mobile terminals; only the corresponding positioning block 300 needs to be installed according to the mobile terminal model before sale, effectively reducing mold costs and inventory, and significantly lowering production costs.

[0050] It is worth mentioning that the installation space 211 adapted to the mobile terminal is used to indicate that the mobile terminal will not shake after being installed in the installation space 211, while the shape of the non-installation space 211 is consistent with the shape of the mobile terminal. For example, there are four positioning blocks 300, which are installed at the four corners of the receiving groove 210. The four positioning blocks 300 are used to position the four corners of the mobile terminal respectively. At this time, the installation space defined by the positioning blocks 300 is different from the shape of the mobile terminal, but the mobile terminal will not shake after being installed in the installation space, so the installation space and the mobile terminal are adapted.

[0051] refer to Figures 3-6 In some embodiments, the mounting base 200 further includes a first positioning structure 220 and a slide rail 230, along the length direction of the mounting base 200 (refer to...). Figure 4 In the X direction shown, the first positioning structure 220 is disposed on one side of the receiving groove 210. The first positioning structure 220 is used to position the film. The slide rail 230 is disposed along the length direction of the mounting base 200. The sliding seat 110 is slidably connected to the mounting base 200 through the slide rail 230. The sliding seat 110 is rotatably connected to the mounting base 200 so that the sliding seat 110 can rotate toward the receiving groove 210 and cover the first positioning structure 220, and so that the sliding seat 110 can rotate away from the receiving groove 210 and expose the first positioning structure 220.

[0052] By implementing this embodiment, before installing the film, the sliding seat 110 can be rotated from its position covering the first positioning structure 220 to its position exposing the first positioning structure 220. This prevents the sliding seat 110 from obstructing the film installation area, facilitating the user's positioning and installation of the film using the first positioning structure 220. After film installation, the sliding seat 110 is simply rotated in the opposite direction, returning from its position exposing the first positioning structure 220 to its position covering the first positioning structure 220. Then, the sliding seat 110 can be moved along the length of the mounting base 200 to apply pressure to the film using the film-pressing structure on the sliding seat 110.

[0053] It is worth mentioning that, in the prior art, to avoid the sliding seat 110 blocking the film installation area, a position adjacent to the installation area is reserved along the length of the mounting seat 200 for the sliding seat 110 to slide out of the film installation area. With this embodiment, it is not necessary to reserve a position along the length of the mounting seat 200 for the sliding seat 110 to slide out of the film installation area, as is the case with the prior art. Therefore, the mounting seat 200 of this embodiment is shorter and uses less material, effectively reducing the production and transportation costs of the film applicator 1000.

[0054] refer to Figures 1-9 In a specific embodiment, the sliding seat 110 is provided with a first rotating shaft 112, and the slide rail 230 is a rib provided on the side wall of the mounting base 200. The rib includes a first extension section 231, a bent section 232, and a second extension section 233. The first extension section 231 is arranged along the length direction of the mounting base 200, and the first rotating shaft 112 is arranged in the direction of gravity of the first extension section 231 (see reference). Figure 5 (in the Y direction). One end of the bent segment 232 is connected to the end of the first extension segment 231 near the first positioning structure 220, and the other end is bent and extended in the direction of gravity. The second extension segment 233 is connected to the other end of the bent segment 232 and extends in the direction of the receiving groove 210.

[0055] Specifically, since the first extension segment 231 is arranged along the length direction of the mounting base 200 in this embodiment, and the first rotating shaft 112 is arranged in the gravity direction of the first extension segment 231, when the sliding seat 110 moves along the length direction of the mounting base 200, the first extension segment 231 can effectively guide the sliding seat 110 to slide along the length direction of the mounting base 200, preventing the sliding seat 110 from moving away from the gravity direction as a whole (see reference). Figure 5 The first pivot 112 moves in the Z direction and disengages from the mounting base 200. The bent section 232 and the second extension section 233 can restrict the position of the first pivot 112 when the slide seat 110 rotates to expose the first positioning structure 220, thus preventing the slide seat 110 from disengaging from the mounting base 200.

[0056] refer to Figures 1-9 In a specific embodiment, the sliding seat 110 is also provided with a rotation limiting block 113, which is spaced apart from the first rotating shaft 112 and is also located in the gravity direction of the first extension 231.

[0057] Specifically, if the rotation angle of the sliding seat 110 can be adjusted during the film application process, the sliding seat 110 may rotate away from the mobile terminal. In this case, the pressure applied by the film-pressing structure will be insufficient, resulting in more air bubbles remaining after the film is applied, leading to a poor user experience. Since this embodiment is provided with a rotation limiting block 113 spaced apart from the sliding seat 110, and the rotation limiting block 113 is also located in the gravity direction of the first extension 231, the rotation limiting block 113 can cooperate with the first rotating shaft 112 and the first extension 231 to limit the rotation of the sliding seat 110.

[0058] Furthermore, to prevent the sliding seat 110 from being restricted from rotating by the rotation limiting block 113 when it slides to cover the first positioning structure 220, this embodiment also provides a second notch 2311 on the first extension section 231. The length of the rotation limiting block 113 is less than the depth of the second notch 2311. When the sliding seat 110 slides to cover the first positioning structure 220, the rotation limiting block 113 and the second notch 2311 are directly opposite each other. In this way, when the sliding seat 110 rotates, the rotation limiting block 113 can pass through the second notch 2311, ensuring that the sliding seat 110 can rotate freely.

[0059] To prevent user error from causing the first pivot 112 to also come out of the second notch 2311, in a specific embodiment, the length of the first pivot 112 is greater than the depth of the second notch 2311. With this setting, even if the first pivot 112 is directly opposite the second notch 2311, it cannot pass through the second notch 2311.

[0060] refer to Figures 1-9 In some embodiments, a second rotating shaft 240 is also provided next to the bent section 232. The second rotating shaft 240 is located on the side of the bent section 232 near the receiving groove 210. The outer surface of the first rotating shaft 112 is provided with a snap-fit ​​groove 1121 that is adapted to the second rotating shaft 240, so that when the sliding seat 110 slides to cover the first positioning structure 220, the second rotating shaft 240 can be inserted into the snap-fit ​​groove 1121. With this configuration, when the sliding seat 110 is flipped, the first rotating shaft 112 can engage with the second rotating shaft 240, avoiding unnecessary shaking when the sliding seat 110 is flipped, and improving the stability of the sliding seat 110 when flipped.

[0061] refer to Figure 4 and Figure 8In some embodiments, the slide rail 230 is disposed on the top of the side wall of the mounting base 200, and a section of the slide rail 230 near the first positioning structure 220 is bent and extended in a direction away from gravity.

[0062] Specifically, if the slide rail 230 is arranged in a straight line, when the sliding seat 110 rotates and exposes the first positioning structure 220, it will collide with the table where the mounting base 200 is placed, and may even cause one end of the mounting base 200 to be raised by the slide rail 110. In order to avoid the sliding seat 110 from contacting the table, in this embodiment, the section of the slide rail 230 near the first positioning structure 220 is bent and extended in a direction away from gravity. In this way, the sliding seat 110 will be raised when it moves to the rotating position, effectively preventing the sliding seat 110 from colliding with the table where the mounting base 200 is placed when it rotates and exposes the first positioning structure 220.

[0063] It is worth mentioning that increasing the overall thickness of the mounting base 200, thus increasing the overall height of the slide rail 230, can prevent the slide base 110 from rotating and exposing the first positioning structure 220, thus avoiding collision with the table where the mounting base 200 is placed. However, this would increase the size and material usage of the mounting base 200, which is not conducive to reducing the production and transportation costs of the applicator 1000.

[0064] refer to Figure 3 In some embodiments, the bottom of the receiving groove 210 is provided with a clearance opening 212, which is used to avoid the camera module of the mobile terminal. The bottom of the mounting base 200 is provided with two sets of support block groups 250 to raise the clearance opening 212. The two sets of support block groups 250 are located in the width direction of the mounting base 200 (refer to...). Figure 10 The interval is set in the M direction.

[0065] Specifically, in the prior art, the camera module of a mobile terminal is generally protruding. To avoid obstructing the camera module, the bottom of the receiving groove 210 is provided with a clearance opening 212. If the clearance opening 212 is too close to the table surface on which the mounting base 200 is placed, the camera module will contact the table surface. To prevent the camera module from contacting the table surface, the prior art raises the clearance opening 212. The prior art provides an annular rib on the edge of the mounting base 200 on the side facing away from the first positioning structure 220. Although the annular rib can raise the height of the clearance opening 212, it consumes too much material, which is not conducive to reducing the production cost of the mounting base 200. To solve this technical problem, this embodiment provides two sets of support block groups 250 at the bottom of the mounting base 200 to raise the clearance opening 212. The two sets of support block groups 250 are spaced apart in the width direction of the mounting base 200. Compared with the rib provided around the edge, it consumes less material and can effectively reduce the production cost of the mounting base 200.

[0066] refer to Figure 7 and Figure 10 Furthermore, each set of support blocks 250 includes a middle support block 252 and two end support blocks 251. The two end support blocks 251 are located on both sides of the middle support block 252 in the length direction of the mounting base 200, and the height of the middle support block 252 is less than that of the two end support blocks 251.

[0067] Specifically, after the mounting base 200 is manufactured, it may undergo slight deformation due to external forces. If the intermediate support block 252 is designed to be at the same height as the end support blocks 251, the slight deformation of the intermediate support block 252 may cause it to protrude beyond the two end support blocks 251, resulting in the mounting base 200 becoming unstable, like a seesaw. Therefore, in this embodiment, the intermediate support block 252 is set shorter than the two end support blocks 251 to avoid the intermediate support block 252 protruding beyond the two end support blocks 251.

[0068] It is worth mentioning that the fact that the middle support block 252 is shorter than the end support block 251 does not mean that the middle support block 252 cannot touch the table. When the slide seat 110 slides towards the position close to the middle support block 252, the pressure applied by the user to the slide seat 110 will only cause a slight deformation of the mounting base 200. At this time, the middle support block 252 can contact the table.

[0069] refer to Figure 6 and Figure 11 In some embodiments, the first positioning structure 220 includes two spaced-apart first positioning hooks 221, and the film is provided with two first hanging holes adapted to the first positioning hooks 221, so that the film can be hooked onto the mounting base 200 by using the first positioning hooks 221 in conjunction with the first hanging holes.

[0070] Furthermore, the mounting base 200 is also provided with a second positioning structure 260. The second positioning structure 260 is located on the side of the receiving groove 210 away from the first positioning structure 220. The second positioning structure 260 includes two spaced second positioning hooks 261. The second positioning hooks 261 face opposite to the first positioning hooks 221. The film is provided with two second hanging holes that are adapted to the second positioning hooks 261. In this way, the stability of the film when it is assembled on the mounting base 200 can be improved by using the cooperation between the second positioning hooks 261 and the second hanging holes.

[0071] The mobile terminal described in this utility model includes, but is not limited to, mobile phones, watches, and tablet computers.

[0072] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
