Description

Technical Field

[0001] This utility model belongs to the field of packaging technology, specifically relating to a film-applying device. Background Technology

[0002] Currently, screen protector application on production lines is mainly divided into fully automatic and semi-automatic methods. While fully automatic equipment is more efficient, its purchase and maintenance costs are also higher. Semi-automatic equipment is less expensive, smaller, and simpler in structure, and is operated manually. Some semi-automatic technologies use specialized molds for the parts to be covered, such as mobile phones, tablets, and screens. The parts are placed in the molds, and then the screen protector is applied manually. While these molds can reduce the difficulty of alignment to some extent, manual alignment is still required, resulting in lower efficiency and a higher risk of air bubbles. Another technology uses two sets of molds, one above the other, to fix the parts to be covered and the screen protector separately before pressing it on. This method is difficult to place and remove the parts and the screen protector, and air bubbles still exist. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a film-applying device that is easy to operate, allows for accurate film alignment, and can expel air bubbles.

[0005] platform; A positioning component is disposed on the platform and is used to position and clamp the component to be coated with film. An adsorption plate is disposed on the platform. The adsorption plate is rotatable and has a first position and a second position. When the adsorption plate is in the first position, it is used to adsorb a protective film on its surface. When the adsorption plate is in the second position, it applies the protective film to the surface of the component to which the film is to be applied.

[0006] According to the film application device of this embodiment, a positioning component is used to position the tablet, mobile phone, or other device to be covered with the film. Then, an adsorption plate is used to pick up the protective film. Compared to handheld protective films, this device is less prone to fingerprints and water vapor adhesion, less likely to generate bubbles, and provides accurate adsorption and positioning. The film is applied by flipping the adsorption plate. Since the positions of the adsorption plate and the positioning component are pre-correlated, the protective film can be quickly and accurately applied to the device to be covered, ensuring both efficiency and accuracy.

[0007] Optionally, the film application device further includes a pressure roller disposed on the platform and positioned above the component to be filmed. The pressure roller is movable relative to the platform in a first direction to expel air bubbles between the protective film and the component to be filmed.

[0008] Optionally, a settling tank is provided on one side of the adsorption plate, the protective film is placed in the settling tank, and a through hole is provided on the bottom wall of the settling tank. One end of the through hole is used to communicate with a negative pressure source so that the protective film is adsorbed in the settling tank under the action of negative pressure.

[0009] Optionally, the adsorption plate has a cavity that communicates with the through hole, and a pipe is provided on the other side of the adsorption plate. One end of the pipe is used to communicate with the negative pressure source, and the other end of the pipe is connected to the settling tank through the cavity and the through hole.

[0010] Optionally, the settling trough has an opening on the side facing the pressure roller in the first direction, and the protective film extends out of the settling trough at the end facing the pressure roller in the first direction.

[0011] Optionally, the positioning component includes a positioning plate disposed on the platform, the positioning plate having a groove, the part to be applied to being placed in the groove, the surface of the part to be applied to being raised above the groove; there is at least one limiting block on each side of the groove, the position of the limiting block is adjustable, the limiting block is used to stop against the part to be applied to being, and the position of the part to be applied to be adjusted by adjusting the position of the limiting block.

[0012] Optionally, the positioning plate is provided with a plurality of limiting grooves corresponding one-to-one with the limiting block, the limiting block is placed in the limiting groove, and the end of the limiting groove near the groove is connected to the groove; the limiting block moves along the limiting groove, the limiting block is provided with an elongated hole, and a clamping bolt is provided in the limiting groove, the clamping bolt passes through the elongated hole, and the clamping bolt is used to fix the limiting block.

[0013] Optionally, the platform is provided with at least one slide rail, which is arranged parallel to the length direction of the positioning component. The slide rail is provided with a mounting seat, which is slidable along the slide rail. The two ends of the pressure roller in the axial direction are mounted on the mounting seat.

[0014] Optionally, the mounting base includes a base plate and a top plate, the base plate slides along the slide rail, and the pressure roller is mounted on the top plate; a plurality of screws are fixed on the base plate, the upper ends of the plurality of screws pass through the top plate, and each screw is equipped with an adjusting nut located on both sides of the top plate, the adjusting nut being used to adjust the height of the top plate.

[0016] The film application device in this embodiment uses negative pressure to adsorb the film, which, compared to manual application, reduces fingerprint adhesion and water vapor generation, thus preventing air bubbles from forming at the source. Furthermore, the grooves on the adsorption plate and the recesses on the positioning plate accurately align the protective film with the part to be applied, ensuring accurate application. Additionally, the slide rail design allows for the reciprocating movement of the adsorption plate; simultaneously, the pressure roller ensures that the protective film is tightly adhered to the flat part awaiting application, and also squeezes out any existing air bubbles.

[0024] The embodiments of this utility model are described in detail below, with examples of the embodiments shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] See appendix Figure 1 The film-applying device of this utility model embodiment includes: a platform 2, a positioning component 3, and an adsorption plate 4. The positioning component 3 is disposed on the platform 2 and is used to position and clamp the part 1 to be applied with film; the adsorption plate 4 is disposed on the platform 2, and the adsorption plate 4 is rotatable and has a first position and a second position. When the adsorption plate 4 is in the first position, the adsorption plate 4 is used to adsorb the protective film on its surface; when the adsorption plate 4 is in the second position, the adsorption plate 4 applies the protective film to the surface of the part 1 to be applied with film.

[0026] The film application device in this embodiment is mainly used to apply factory-installed protective films to components 1, such as the screens of electronic products like mobile phones and tablets. The protective film can be either soft or hard, but is generally made of soft plastic. In use, the suction plate 4 is placed in a first position, away from the component 1. The protective film is then manually placed on the suction plate 4, and the surface sticker is peeled off. The component 1 is then placed on the positioning assembly 3. The suction plate 4 is then adjusted to a second position, at which point the protective film is applied to the component 1.

[0027] In this embodiment, the film-applying device uses an adsorption plate 4 to adsorb the protective film and a positioning component 3 to position and clamp the part 1 to be applied to; the two work together to achieve the film-applying operation. Compared to manual hand-held film application, this method effectively avoids fingerprints, sweat, hair, etc., adhering to the film during operation, thus preventing air bubbles. Furthermore, placing the protective film on the adsorption plate 4 facilitates positioning and pressing, ensuring accurate application. Appropriate pressing ensures a firm fit and, to some extent, squeezes out excess air bubbles.

[0028] In some specific embodiments, platform 2 may consist of upper and lower plates, with the two side plates supported by vertical plates. Positioning component 3 is installed on the upper plate.

[0029] In some specific embodiments, the positioning component 3 can take various forms, as long as it can securely hold the component 1 to be applied with film. It must also ensure that the position of the component 1 remains consistent each time it is replaced. For example, it can be multiple clips, positioning rods in four directions, or even a slot, etc. The positioning component 3 secures the component 1 to be applied with film in a fixed position.

[0030] In some specific embodiments, the adsorption plate 4 is flippable. For example, one side of the adsorption plate 4 can be directly hinged to the platform 2 or flipped after cooperation with other components. The adsorption plate 4 can adsorb the protective film onto its surface through electrostatic, negative pressure, adhesive, or slot methods. Each time the protective film is placed, it should be placed in a consistent position to ensure accurate alignment between the protective film and the component 1 to be covered. In the first position, the adsorption plate 4 is away from the component 1 to be covered, which can be a vertical position or another position away from the component 1 to be covered. This facilitates manual adsorption of the protective film onto the adsorption plate 4. After the protective film is placed, the inner sticker of the protective film is manually peeled off, and then the adsorption plate 4 is moved to the second position. In the second position, the protective film is adhered to the component 1 to be covered, and at this time, the protective film can be applied to the component 1 to be covered.

[0031] In some embodiments, the film application device further includes a pressure roller 5, which is disposed on the platform 2 and can be positioned above the component 1 to be applied to. The pressure roller 5 can move relative to the platform 2 in a first direction to squeeze out air bubbles between the protective film and the component 1 to be applied to.

[0032] Generally, the first direction can be along the length of the component 1 to be covered with film, i.e., the attachment direction. Figure 1 The left and right directions are indicated by the middle arrow. In this embodiment, the pressure roller 5 can be a single roller, rolled by hand, or it can be mounted on the platform 2 as an integral part of the platform 2 via other components. The outer layer of the pressure roller 5 can be a rubber layer or other soft material to avoid damage to the screen. The pressure roller 5 can be rotated to improve rolling efficiency and facilitate rapid rolling. The pressure roller 5 can also be non-rotating. When non-rotating, the pressure roller 5 can have a rectangular cross-section, as long as one side is in contact with the surface of the component 1 to be coated. This allows air bubbles to be squeezed out better when the pressure roller 5 moves.

[0033] In some embodiments, a settling tank 41 is provided on one side of the adsorption plate 4, and a protective film is placed in the settling tank 41. A through hole 42 is provided on the bottom wall of the settling tank 41, and one end of the through hole 42 is used to communicate with a negative pressure source so that the protective film is adsorbed in the settling tank 41 under the action of negative pressure.

[0034] In this embodiment, the film application device uses a recess 41 to position the protective film, and then uses negative pressure to adsorb the protective film, ensuring that the protective film is always placed in the same position, facilitating accurate alignment between the protective film and the part 1 to be applied. The negative pressure allows for rapid adsorption and detachment without damaging the protective film.

[0035] In some specific embodiments, the protective film and the recess 41 are gap-fitted, that is, after the protective film is placed in the recess 41, a gap of 0.5-1mm is left around it, which can facilitate the placement of the protective film in the recess 41 without affecting the accuracy of film application.

[0036] In some specific embodiments, the depth of the groove 41 is generally the same as the depth of the protective film or slightly less than the thickness of the protective film. Even if the depth of the groove 41 is greater than the protective film, it will not affect the use, because the surface of the part 1 to be covered with the film is raised, and it can still be accurately attached.

[0037] In some specific embodiments, the adsorption of the protective film is achieved using negative pressure. Specifically, this is achieved by creating a through-hole 42 at the bottom of the settling tank 41 and connecting it to a negative pressure source, such as a centralized negative pressure port in a factory or a suction pump, in conjunction with a manual control switch. After the protective film is placed in the settling tank 41, activating the negative pressure source enables the adsorption of the protective film. This eliminates the need for hand-applying the film, as the adsorption plate 4 not only makes operation convenient but also avoids the air bubble problem associated with hand-applying the film.

[0038] In some embodiments, the adsorption plate 4 has a cavity that communicates with the through hole 42. The other side of the adsorption plate 4 is provided with a pipe 43. One end of the pipe 43 is used to communicate with a negative pressure source, and the other end of the pipe 43 is connected to the settling tank 41 through the cavity and the through hole 42.

[0039] In this embodiment, the film-applying device utilizes the cavity of the adsorption plate 4 as an intermediate connector to facilitate the connection between the negative pressure source and the through hole 42, and also provides a certain buffering effect.

[0040] In some specific embodiments, multiple through holes 42 are provided, and the cavity is connected to multiple through holes 42. This allows different positions of the protective film to be adsorbed simultaneously, ensuring the stability of the protective film adsorption and preventing bending.

[0041] In some embodiments, see Figure 2 The settling trough 41 has an opening on the side facing the pressure roller 5 in the first direction, and the protective film extends out of the settling trough 41 at the end facing the pressure roller 5 in the first direction.

[0042] In other words, the length of the suction plate 4 in the first direction is less than the length of the protective film, causing the end of the protective film facing the pressure roller 5 to extend outwards. In the second position, the back side of the protective film adjacent to the pressure roller 5 is not blocked by the suction plate 4. In this state, the film may not yet be fully adhered to the part 1 to be covered. At this time, the suction plate 4 remains stationary, and the pressure roller 5 moves along the first direction and presses on the extended part of the protective film, so that the extended part of the protective film is fully adhered to the screen, and the position of the protective film no longer wobbles. After the negative pressure source is turned off, the suction plate 4 can be removed, or the pressure roller 5 can continue to move and push the suction plate 4 away. Through this embodiment, the extended part of the protective film can be used to pre-apply a portion of the protective film, preventing the protective film from shifting and causing positional deviation due to the direct removal of the suction plate 4.

[0043] In some embodiments, the positioning component 3 includes a positioning plate 31 disposed on the platform 2. The positioning plate 31 has a groove 32. The part to be covered with film 1 is placed in the groove 32, and the surface of the part to be covered with film 1 is higher than the groove 32. There is at least one limiting block 33 on each side of the groove 32. The position of the limiting block 33 is adjustable. The limiting block 33 is used to stop against the part to be covered with film 1. The position of the part to be covered with film 1 can be adjusted by adjusting the position of the limiting block 33.

[0044] In the film application device of this embodiment, the component 1 to be applied to is accurately positioned by the limiting block 33 and the groove 32. The component is easy to place, and the position of the component 1 to be applied to can be finely adjusted by adjusting the position of the limiting block 33. Alternatively, for components 1 of different sizes, positioning and clamping can be achieved by moving the limiting block 33. The surface of the component 1 to be applied to protrude above the groove 32, facilitating the application of the protective film to the surface of the component 1.

[0045] In some specific embodiments, the groove 32 can be clearance-fitted with the component 1 to be coated, that is, after the component 1 is placed in the groove 32, a gap of 0.5-1mm is left around it. In this embodiment, the size of the groove 32 is larger than that of the component 1 to be coated. By adjusting the position of the limiting blocks 33 around the groove 32, the position of the component 1 to be coated can be adjusted and locked. To adapt to different types and sizes of components 1 to be coated, the corresponding groove 41 on the adsorption plate 4 is also adjusted, or a different model of adsorption plate 4 can be replaced.

[0046] In some embodiments, the positioning plate 31 is provided with a plurality of limiting grooves 34 corresponding one-to-one with the limiting blocks 33, and the limiting blocks 33 are placed in the limiting grooves 34. The end of the limiting groove 34 near the groove 32 is connected to the groove 32. The limiting block 33 is provided with an elongated hole 331, and a clamping bolt 35 is provided in the limiting groove 34. The clamping bolt 35 passes through the elongated hole 331 and is used to fix the limiting block 33.

[0047] In the film-applying device of this embodiment, after the limiting block 33 moves toward the center of the groove 32, it can completely disengage from the limiting slide 34 and be placed inside the groove 32, ensuring that the limiting block 33 can move and stop against the part 1 to be applied to. After tightening the clamping bolt 35, since the size of the female head of the clamping bolt 35 is larger than the oblong hole 331, the female head of the clamping bolt 35 will press the limiting block 33 into the limiting slide 34, thereby realizing the movement and fixation of the limiting block 33. Through the cooperation of the limiting slide 34 and the limiting block 33, the position of the limiting block 33 can be adjusted. As mentioned above, the position can be easily adjusted or it can be used for parts 1 to be applied to with different sizes of film.

[0048] In some specific embodiments, a groove and a protrusion that fit together are provided between the side wall of the limiting block 33 and the side wall of the limiting slide groove 34. For example, the protrusion on the limiting block 33 is placed in the groove in the limiting slide groove 34 to achieve stable and accurate sliding of the limiting block 33.

[0049] In some embodiments, each limiting block 33 has several bolt holes, and each limiting groove 34 also has several bolt holes. By using bolts to pass through the limiting block 33 and connect with the bolt holes on the limiting groove 34, the limiting block 33 and the limiting groove 34 are fixed together. By selecting different bolt holes, the limiting block 33 can be placed in different preset positions, thereby quickly adapting to film-to-be-applied parts 1 of different sizes.

[0050] In some specific embodiments, the limiting block 33 on one side or adjacent sides of the groove 32 can be elastically reset. That is, a compression spring is provided between the limiting block 33 and the limiting slide 34. By moving the limiting block 33, it is convenient to release the limiting block 33 after the film-to-be-applied component 1 is placed in, and the limiting block 33 stops against the film-to-be-applied component 1 under the action of the compression spring. This realizes the quick installation and positioning of the film-to-be-applied component 1.

[0051] In some embodiments, the platform 2 is provided with at least one slide rail 6, which is arranged parallel to the length direction of the positioning component 3. The slide rail 6 is provided with a mounting seat 7, which is slidable along the slide rail 6. The two ends of the pressure roller 5 in the axial direction are mounted on the mounting seat 7. The cooperation between the slide rail 6 and the mounting seat 7 enables the pressure roller 5 to move stably, ensuring smooth extrusion of air bubbles without damaging the film-to-be-applied component 1.

[0052] In some specific embodiments, two slide rails 6 may be provided, arranged on the lower layer of platform 2, with the two slide rails 6 located on both sides of positioning component 3. The connection between pressure roller 5 and mounting base 7 can be a rotatable connection or a fixed connection. A handle may also be provided at one end of pressure roller 5 for gripping, further facilitating operation and enhancing the stability of pressure roller 5 movement.

[0053] In some embodiments, the mounting base 7 includes a base plate 71 and a top plate 72. The base plate 71 slides along the slide rail 6, and the pressure roller 5 is mounted on the top plate 72. A plurality of screws 73 are fixed on the base plate 71, with the upper ends of the screws 73 passing through the top plate 72. Each screw 73 is equipped with an adjusting nut located on both sides of the top plate 72, which is used to adjust the height of the top plate 72. Through this embodiment, the height of the pressure roller 5 can be adjusted, ensuring the degree and force of the roller pressure, and it can also adapt to film-to-be-applied components 1 of different thicknesses.

[0054] In some specific embodiments, the base plate 71 is positioned between the upper and lower plates of the platform 2 and is attached to the lower plate, allowing the mounting base 7 to move along the platform 2. The height of the top plate 72 is adjusted by turning the adjusting nuts. After the adjusting nuts on both sides are tightened, the height of the top plate 72 is fixed. Consequently, the distance between the pressure roller 5 and the surface of the part 1 to be coated is also determined.

[0055] In some embodiments, as shown in the appendix Figure 1 As shown, a base 8 is provided on any one of the slide rails 6, and the adsorption plate 4 is hinged to the base 8; the base 8 can slide along the slide rail 6; the adsorption plate 4 moves with the base 8 to the second position after it is aligned with the part to be applied to the film 1 and flipped towards the part to be applied to the film 1; the adsorption plate 4 flips to the vertical position and moves with the base 8 to the first position after it is far away from the part to be applied to the film 1.

[0056] In the film application device of this embodiment, the adsorption plate 4 is installed through the base 8, which can move along the guide rail, ensuring the stable and accurate movement of the adsorption plate 4.

[0057] The complete operation process is as follows: First, move the base 8 away from the pressure roller 5 to one end of the slide rail 6, and flip the adsorption plate 4 to a vertical or horizontal position with the sink 41 facing upwards; this is the first position of the adsorption plate 4, away from the part 1 to be covered with film, and after the adsorption plate 4 is flipped to a vertical position, it is convenient to put the protective film into the sink 41. Then, the operator starts the negative pressure source to adsorb the protective film onto the adsorption plate 4. Simultaneously, the part 1 to be covered with film is also placed into the sink 41 of the positioning plate 31, and the position of the limiting block 33 is fixed. Then, move the base 8 towards the pressure roller 5 until the maximum stroke of the base 8 is reached. At this time, the base 8 stops against the mounting base 7, and the base 8 no longer moves. Flip the adsorption plate 4 towards the part 1 to be covered with film, and apply the protective film to the part 1 to be covered with film; this is the second position of the adsorption plate 4. In the second position, the negative pressure source can be turned off, and the adsorption plate 4 can be kept stationary. Then, the pressure roller 5 is moved to the protective film and moves along the first direction, i.e., the length direction of the part to be covered with the film 1. The pressure roller 5 presses the protruding part of the protective film so that it is completely adhered to the screen of the part to be covered with the film 1. Then, the pressure roller 5 continues to move, and the mounting base 7 of the pressure roller 5 will drive the base 8 to move together, thereby completely detaching the adsorption plate 4 from the part to be covered with the film 1. At the same time, the pressure roller 5 also presses the entire protective film completely onto the part to be covered with the film 1.
