Description

Technical Field

[0001] This utility model relates to the field of film-applying fixture technology, and in particular to a film-applying fixture. Background Technology

[0002] Currently, fixtures used for surface coating of electronic products generally suffer from narrow application range, large size, and cumbersome operation, causing inconvenience to production and use. Common fixture types and their problems are listed below:

[0003] The first type of screen protector application fixture is a single-model fixture, which involves creating a corresponding plastic mold for each component (such as a mobile phone) to be covered with a screen protector. This type of fixture has the following problems: A. Because a corresponding plastic mold needs to be created for each component to be covered with a screen protector, not only is the production efficiency low, but it is also difficult to make a suitable fixture due to the difficulty in timely grasping new device data; B. Because it is difficult to ensure reasonable inventory data, it is easy to cause huge inventory risks and waste for manufacturing companies, including significant losses in space, materials, and profits; C. Customer needs cannot be met in a timely and reasonable manner, resulting in customer complaints and affecting the density of cooperation.

[0004] The second type of film-applying fixture (also called a universal data hole tail plug fixture) is a film-applying fixture that requires a semi-broken line and a micro-adhesive layer to be made on the protective film and release film of the film-applying component to assist in film application. This type of film-applying fixture not only has poor film application accuracy and high operation difficulty, but also leaves an obvious mark in the middle of the protective film layer after film application, which seriously affects the user experience.

[0005] The third type of film-applying fixture (also called universal foam applicator or insert-type sliding film-applying fixture) is relatively universal and larger, but it has the following problems: A. This type of fixture is usually large, resulting in higher material, packaging, and logistics costs; B. The film-applying process is more complex, less efficient, wastes labor costs, and has a higher selling price; C. When there are slow-selling models, a large amount of inventory will lead to a waste of space and materials.

[0006] Therefore, it is necessary to develop a simple and universal film-applying fixture. Utility Model Content

[0007] To solve the above technical problems, this utility model provides a universal film-applying fixture that is simple in structure and easy to use.

[0008] A film-applying fixture includes a positioning seat for fixing a component to be applied with film. The positioning seat includes a base and a side wall fixed on the base.

[0012] As a further improvement, the positioning seat also includes a fixing mechanism for fixing the film application assembly; the film application fixture also includes a pressing device slidably connected to the positioning seat, wherein when the part to be filmed is pressed, the pressing device slides back and forth to press the film application assembly fixed to the fixing mechanism, thereby applying the protective film of the film application assembly to the surface of the part to be filmed.

[0013] As a further improvement, the pressing device can also rotate relative to the positioning seat to open from the positioning seat and cover the positioning seat; when covered by the positioning seat, the protective film of the film application assembly fixed to the fixing mechanism is pressed back and forth to apply the film; and the film application assembly and the part to be applied are installed and removed by opening from the positioning seat.

[0014] As a further improvement, the positioning seat is provided with a limiting device, which restricts the pressing device from sliding back and forth to achieve rotation of the pressing device relative to the positioning seat; the sliding component is at least partially disposed in the area enclosed by the base and the side wall, and the sliding component presses and releases the part to be applied within the area enclosed by the base and the side wall by sliding back and forth.

[0015] As a further improvement, the pressing device includes a pressing part and a rotating shaft that are fixedly connected. The limiting device restricts the back-and-forth sliding of the rotating shaft to enable the pressing device to rotate relative to the positioning seat with the rotating shaft as the rotation axis. The pressing part includes a floating base and a pressing body connected to the floating base that is in close contact with the film application assembly when applying film to the film-to-be-applied component. The part of the pressing body that is in close contact with the film application assembly is made of soft material.

[0016] As a further improvement, the component to be applied is positioned within the area enclosed by the base, front sidewall, left sidewall, right sidewall, and sliding assembly when clamped; the limiting device is located on the outer side of the left sidewall and / or right sidewall away from the front sidewall; a protruding strip is fixedly provided on the outer side of the left sidewall and / or right sidewall; the pressing device further includes a latching part fixedly connected to the pressing part, the pressing part and the latching part forming a sliding groove, the sliding groove being fitted over the protruding strip; the pressing device is pushed to slide back and forth along the protruding strip; the protruding strip has a notch, and when the sliding pressing device restricts the rotating shaft within the area enclosed by the limiting device, the latching part slides into the notch; when the latching part slides into the notch, the pressing device is rotated, causing the pressing device to rotate relative to the positioning seat; the pressing body is fixedly or rotatably connected to the floating base; the soft material is an elastic material and / or cloth.

[0017] As a further improvement, the elastic squeezing component, when clamping the component to be coated, has a portion that contacts the component close to its front end; both the left and right squeezing units are arc-shaped; the base is provided with a slide rail, and the bottom of the sliding component slides back and forth along the slide rail; the outer ends of the left and right side walls away from the limiting device are provided with blocking parts to prevent the pressing device from sliding; the component to be coated is a mobile phone; the coating assembly includes an upper protective layer and a protective film application layer that are tightly attached in sequence, and the protective film application layer is pressed by pressing the upper protective layer and the protective film application layer of the coating assembly fixed to the fixing mechanism; the fixing mechanism includes at least two fixing mechanism units fixed to the front side wall of the positioning base and at least two protrusions fixed to the sliding component, and the coating assembly is fixed to the fixing mechanism by one end of the upper protective layer being sleeved outside each fixing mechanism unit and the other end being sleeved outside each protrusion.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model is equipped with an elastic extrusion component. The elastic extrusion component clamps the film-to-be-applied component placed in the area enclosed by the base and side wall by extruding the left and / or right sides of the film-to-be-applied component, thereby preventing the film-to-be-applied component from moving in the left and right directions. This achieves extrusion of the film-to-be-applied component from both left and right sides. Because the elastic extrusion component is elastic, it can clamp film-to-be-applied components of different widths, so that the film-applied fixture can apply film to film-to-be-applied components of different widths. It does not require making a corresponding plastic mold for each film-to-be-applied component (such as a mobile phone), and has a wide range of applications.

[0037] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] A film-applying fixture includes a positioning seat 1 for fixing a component 5 to be applied with film. The positioning seat 1 includes a base 19 and a side wall 20 fixedly disposed on the base 19. The side wall 20 is provided with an elastic pressing member 2. The elastic pressing member 2 clamps the component 5, which is placed within an area 10 enclosed by the base 19 and the side wall 20, by pressing the left and / or right sides of the component 5 to prevent the component 5 from moving in the left-right direction. Movement can also be sliding. The area enclosed by the base and the side wall is also the area enclosed by the base and the side wall.

[0040] The base and sidewalls can form a groove or frame. The part to be coated can be placed inside the groove or frame.

[0041] This invention utilizes an elastic compression component 2. This component 2 clamps the film-to-be-applied component 5, which is placed within the area enclosed by the base and side wall, by squeezing the left and / or right sides of the component 5 to prevent it from moving in the left-right direction. This allows for compression of the film-to-be-applied component 5 from both sides. Because the elastic compression component 2 is elastic, it can clamp film-to-be-applied components 5 of different widths, enabling the film-applied fixture to apply film to components of different widths, thus broadening its application range.

[0042] This invention has a wide range of applications, thus eliminating the need to manufacture multiple film-applying fixtures, reducing inventory pressure, and saving resources.

[0043] Preferably, the elastic compression component includes a left compression unit 21 and a right compression unit 22, which are respectively fixedly connected to the side wall. The left compression unit 21 and the right compression unit 22 compress the left and right sides of the component to be coated, respectively, to secure the component 5, which is placed within the area enclosed by the base 19 and the side wall 20. By providing the left and right compression units, the component to be coated can be compressed and secured from both sides (the left compression unit 21 compresses the left side and the right compression unit 22 compresses the right side). This allows for better compression of the component 5, ensuring that it is securely held between the left side wall 17 and the right side wall 18.

[0044] Preferably, the sidewall includes a front sidewall 15, a left sidewall 17, and a right sidewall 18.

[0045] Preferably, one end of the left extrusion unit 21 is fixedly connected to the left side wall 17, and the other end is inclined towards the right side wall 18; one end of the right extrusion unit 22 is fixedly connected to the right side wall 18, and the other end is inclined towards the left side wall 17; the left extrusion unit 21 and the right extrusion unit 22 are symmetrically arranged on both sides of the clamped film-to-be-applied component 5. This structure allows the film-to-be-applied component to be clamped between the left and right side walls, achieving automatic centering. In the prior art, when the film-applied component is fixed to the positioning seat, the protective film layer is generally also set in the middle of the positioning seat, directly above the film-to-be-applied component. When the film-to-be-applied component is centered, it is very convenient to ensure that the surface of the film-applied component to be covered by the protective film layer is completely covered without deviation.

[0046] Preferably, the positioning seat 1 further includes a sliding component 3 slidably disposed on the base 19. The sliding component 3 presses and releases the part 5 to be applied by sliding back and forth, that is, pressing and releasing between the front sidewall 15 and the sliding component 3; the sliding component 3 prevents the part 5 to be applied from moving in its front-back direction by pressing it. By setting the sliding component 3, parts 5 of different lengths to be applied can be pressed, further expanding the versatility of the film application fixture. The combination of the elastic extrusion component 2 and the sliding component 3 enables the film application fixture to apply films to parts 5 of different lengths and widths, with excellent size compatibility. The combination of the elastic extrusion component 2 and the sliding component 3 achieves stepless adjustment, that is, adaptive stepless adjustment.

[0047] Preferably, the elastic extrusion component is fixedly disposed on the inner side of the side wall (i.e., the elastic extrusion component is fixedly disposed on the inner side of the side wall). This arrangement is more reasonable and easier to manufacture.

[0048] Preferably, the front sidewall, left sidewall, and right sidewall 18 are all fixedly mounted on the base 19.

[0049] Preferably, the positioning seat 1 further includes a fixing mechanism for fixing the film application assembly 7; the film application fixture further includes a pressing device slidably connected to the positioning seat 1. When the part 5 to be filmed is pressed, the pressing device slides back and forth to press the film application assembly 7, which is fixed to the fixing mechanism 6, so that the protective film of the film application assembly 7 is applied to the surface of the part 5 to which the film needs to be applied. The pressing device makes it very convenient to press and apply the film.

[0050] When the component 5 to be coated with film is pressed, the protective film of the film-coating assembly 7, which is fixed to the fixing mechanism 6, is applied to the component to be coated with film. Since the film-coating assembly 7 is fixed to the fixing mechanism 6, it is convenient to use. At the same time, since the film-coating assembly 7 can be fixed to the fixing mechanism 6 for film application, it is not necessary to align each film-coating assembly 7, making alignment easy and achieving precise film application.

[0051] Preferably, the pressing device can also rotate relative to the positioning seat 1 to open from the positioning seat 1 and cover the positioning seat 1; the protective film layer of the film application component 7, which is fixed to the fixing mechanism, is pressed back and forth when it is covered by the positioning seat 1 to apply the film (i.e., the film application component 7 is fixed to the fixing mechanism 6, and the protective film layer of the film application component 7 is applied to the surface of the part 5 to be filmed by pressing the film application component 7). The film application component 7 and the part 5 to be filmed can be installed and removed by opening from the positioning seat 1. This structure enables quick and convenient film application. The installation and removal of the part 5 to be filmed may also include placing and removing the part 5 to be filmed.

[0052] Preferably, the positioning seat 1 is provided with a limiting device 11, which restricts the pressing device from sliding back and forth to achieve the rotation of the pressing device relative to the positioning seat 1; the sliding component 3 is at least partially disposed in the area enclosed by the base and the side wall, and the sliding component 3 presses and releases the film-to-be-applied component 5 in the area enclosed by the base and the side wall by sliding back and forth.

[0053] Preferably, the pressing device includes a pressing part 43 and a rotating shaft 42 fixedly connected. The limiting device 11 restricts the sliding of the rotating shaft 42, thereby enabling the pressing device to rotate relative to the positioning seat 1 with the rotating shaft 42 as the rotation axis. The pressing part 43 includes a floating base 46 (also called a base) and a pressing body 44 connected to the floating base, which is in close contact with the film-applying assembly when applying film to the component to be applied. The part of the pressing body 44 in close contact with the film-applying assembly is made of a soft material. The pressing body 44 is fixedly connected to the floating base. The soft material can be an elastic material and / or cloth. The elastic material can be silicone rubber, polyurethane, or sponge; the cloth can also be a fabric, such as cotton. The floating base can be a frame. The part of the pressing body 44 in close contact with the film-applying assembly is made of a soft material, which allows for good contact with the film-applying assembly and reduces the risk of damage to the film-applying assembly and the component to be applied.

[0054] The pressing device 4 slides back and forth relative to the positioning seat 1. When the rotating shaft 42 moves to the area enclosed by the limiting device 11, the pressing device 4 can rotate relative to the positioning seat 1 due to the restriction of the limiting device 11. The limiting device can be an annular protrusion fixedly connected to the side wall. The front side of the annular protrusion is thinner, which makes it easier for the rotating shaft to slide into the area enclosed by the annular protrusion (or the limiting device).

[0055] In use, rotate the pressing device 4 to open the gap between the pressing device 4 and the positioning seat 1, facilitating the installation of the part to be covered 5 and the film application assembly 7. After the part to be covered 5 and the film application assembly 7 are installed, rotate the pressing device 4 so that the pressing device 4 covers the positioning seat 1. At this time, push the pressing device 4 so that the pressing device 4 slides back and forth relative to the positioning seat 1 to press the film application assembly 7 to apply the film. Thus, the protective film layer of the film application assembly 7 is applied to the part to be covered 5. After applying the film, rotate the pressing device 4 to open the gap between the pressing device 4 and the positioning seat 1, remove the other parts of the fixing mechanism that fix the film application assembly 7, move the sliding component 3 to release the part to be covered 5, and then remove the part to be covered 5.

[0056] Preferably, the film-to-be-applied component 5, when clamped, is positioned within the area enclosed by the base 19, front sidewall 15, left sidewall 17, right sidewall 18, and sliding assembly 3; the limiting device 11 is positioned on the outer side of the left sidewall 17 and / or right sidewall 18 near the end of sliding assembly 3 (the end away from the front sidewall); a protrusion 12 is fixedly provided on the outer side of the left sidewall 17 and / or right sidewall 18; the pressing device 4 further includes a latching part 41 fixedly connected to the pressing part, the pressing part 43 and the latching part 41 forming a sliding groove 45, the sliding groove 45 being fitted over the protrusion 12; the protrusion 12 has a notch 14, when the sliding pressing device 4 restricts the rotating shaft 42 within the area enclosed by the limiting device 11, the latching part 41 slides into the notch 14. When the latching part 41 slides into the notch 14, the pressing device 4 is rotated, thereby allowing the pressing device 4 to rotate relative to the positioning seat 1.

[0057] When the film application assembly 5 is fixed to the positioning mechanism 6 and the part 5 to be filmed is pressed, the protective film layer 74 of the film application assembly 7 is positioned directly above the part to be filmed. This alignment ensures that when the protective film layer of the film application assembly is pressed, it is precisely applied to the surface of the part to be filmed, without any deviation. The protective film layer of the film application assembly matches the surface of the part to be filmed, and it completely covers the surface of the part to be filmed. This further achieves precise film application.

[0058] Preferably, when the elastic squeezing member 2 clamps the film-to-be-applied member 5, the portion in contact with the member 5 is close to the front end of the member 5 (the end of the member 5 closest to the front sidewall 15); both the left and right squeezing units are arc-shaped (such as arc-shaped strips or arc-shaped pieces); the base 19 is provided with a slide rail 16, and the bottom of the sliding assembly 3 slides back and forth along the slide rail 16; the outer ends of the left sidewall 17 and right sidewall 18, away from the limiting device 11, are provided with blocking portions 13 to prevent the pressing device 4 from sliding. The portion of the elastic squeezing member 2 in contact with the member 5 when clamping it is close to the front end of the member 5, thus better clamping the member 5. The slide rail 16 makes the sliding assembly slide more conveniently.

[0059] The blocking part 13 is used to prevent the pressing device 4 from sliding, thereby ensuring that the pressing device 4 slides within a certain area (between the blocking part 13 and the area limited by the limiting device 11), which is convenient to use.

[0060] Preferably, the component 5 to be covered with the screen protector is a mobile phone; the screen protector assembly 7 includes an upper protective layer 73 and a protective film application layer 74 that are sequentially and tightly attached. The protective film application layer is applied by pressing the upper protective layer 73 and the protective film application layer, which are fixed to the fixing mechanism 6; the fixing mechanism 6 includes at least two fixing mechanism units 61 fixedly disposed on the front side wall 15 of the positioning seat 1 and at least two protrusions 62 fixedly disposed on the sliding assembly 3. The screen protector assembly 7 is fixed to the fixing mechanism 6 by one end of the upper protective layer 73 being sleeved outside each fixing mechanism unit and the other end being sleeved outside each protrusion. Preferably, there are two fixing mechanism units and two protrusions (or tabs), which is convenient to use and saves materials and processes.

[0061] Preferably, the film application assembly 7 includes an upper protective layer 73, a protective film usage layer 74, and a lower protective layer that are sequentially and tightly attached to each other. The lower protective layer includes an adhesive portion 72 that is tightly attached to the protective film usage layer and a tear-off portion 71 connected to the adhesive portion 72. When the film application assembly 7 is fixed to the fixing mechanism 5, the film application assembly 7, the front sidewall, the base, and the two fixing mechanism 6 units of the fixing mechanism 6 can form a gap 8 through which the tear-off portion 71 passes. By pulling the part of the tear-off portion 71 that passes through the gap 8, the lower protective layer is torn off from the film application assembly 7. When the mobile phone is pressed, the gap 8 is located near the short side of the mobile phone. This makes it convenient and easy to use. The tear-off portion 71 can be located below the adhesive portion 72.

[0062] For illustrations of the above embodiments, please refer to... Figure 1-9 .

[0063] The component 5 to be covered with the film can be a product such as a mobile phone that requires a film to be applied. Now, taking a mobile phone as the component 7 to be covered with the film as an example, the practical method of the film application fixture of this application will be described.

[0064] In use, rotate the pressing device 4 and place the phone in the area enclosed by the bottom, front side wall 15, left side wall 17, right side wall 18, and sliding component 3. Slide the phone so that one end of the phone is close to the front side wall 15, and the elastic squeezing component 2 clamps the two sides of the phone (i.e., clamps along the width direction). Move the sliding component 3 to press the phone from both ends (also clamps along the length direction). Then fix the screen protector component 7 on the fixing mechanism 6 and peel off the lower protective layer of the screen protector component 7. Rotate the pressing device 4 so that the pressing device 4 covers the positioning seat 1. Then push the pressing device 4 so that the pressing device 4 slides back and forth relative to the positioning seat 1 to apply the screen protector, thereby achieving the application of the protective film layer onto the phone screen. After the screen protector is applied, rotate the pressing device 4 to expose the upper protective layer. Remove the upper protective layer 73 from the positioning seat 1 and push the sliding component 3 to move the sliding component 3 away from the front side wall 15. Remove the phone with the screen protector applied. This completes the screen protector application process and is convenient to use.

[0065] This utility model of film-applying fixture has a simple structure, small size, is easy to use, allows for quick film application, and is lightweight. Due to its small size and weight, it also reduces packaging costs, logistics costs, warehousing costs, and production costs.

[0066] When the device to be covered with a screen protector is a mobile phone, this screen protector fixture is applicable to the vast majority of mobile phones on the market.

[0067] The elastic extrusion member 2 can extrude the left and / or right side of the film-to-be-applied component 5 by extruding the left and / or right side wall of the film-to-be-applied component 5.

[0068] The left-right direction of this utility model refers to the width direction of the component to be covered with the film (such as a mobile phone), for example, it can be as follows: Figure 8 The direction perpendicular to the reading surface. The front-to-back direction is the length direction of the part to be covered (such as a mobile phone), for example, it could be... Figure 1 The left and right directions are shown. The length direction of the positioning base, for example, could be... Figure 1 The left and right directions are shown.

[0069] Example 2

[0070] Similar to the other structures in Embodiment 1, the difference lies in that the pressing body 44 is rotatably connected to the floating base 46. This rotatable connection allows the pressing body to rotate relative to the floating base during sliding, making it easier to move the pressing device and facilitating film application.

[0071] However, the above description is merely a preferred embodiment of this utility model and should not be construed as limiting the scope of this utility model. Any simple equivalent changes and modifications made based on the content described in the claims and specification of this utility model shall still fall within the scope of the claims. Furthermore, the abstract and title are merely for assisting in patent document searching and are not intended to limit the scope of this utility model.
