[0002] With the widespread use of electronic devices such as smartphones and tablets, the demand for screen protectors has increased dramatically. Traditional screen protector application methods mainly rely on manual operation, which, while flexible, has many limitations. First, manual application is inefficient and cannot meet the needs of large-scale production. Second, manual operation inevitably introduces air bubbles or dust, leading to inconsistent application quality and affecting the product's appearance and user experience. Furthermore, manual application is more difficult for some complex-shaped or small electronic devices, and is prone to positional errors. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic film applicator that can improve the accuracy and stability of film application, thereby enhancing the quality of the applied film.
[0004] An automatic film applicator according to a first aspect of the present invention is used for applying protective films to electronic devices, comprising:
[0005] Base;
[0006] A clamping assembly is mounted on the base, the clamping assembly is provided with a first locking block, the first locking block is movably connected to the base, and the first locking block is connected to a reset member to limit the electronic device;
[0007] An exhaust mechanism is connected to the base. The exhaust mechanism includes a power component and a movable support. The power component is used to drive the movable support to move above the electronic device. An exhaust roller is provided on the bottom surface of the movable support. The exhaust roller is used to press the protective film on the electronic device to expel the air between the protective film and the electronic device.
[0008] An automatic film applicator according to an embodiment of the present invention has at least the following beneficial effects: The design of the clamping assembly and the first locking block securely limits the position of the electronic device, ensuring that the device will not shift during the film application process, thereby improving the accuracy of the film application; the exhaust roller in the exhaust mechanism can move between the protective film and the electronic device, effectively compressing and expelling the air between them, significantly reducing the potential air bubble problem after film application and ensuring the quality of the film application; the automated operation of the power component driving the moving support and the exhaust roller not only improves work efficiency but also reduces errors that may be caused by manual operation, making the film application process more stable and reliable; the first locking block is connected to a reset component, which can automatically return to the initial state after film application or position adjustment, facilitating the next operation and simplifying the operation process; using this machine for film application can achieve higher quality protective film coverage, extend the service life of electronic devices, and avoid problems that may be encountered when manually applying film, such as dust entry, hand tremors, etc., leading to film application failure.
[0009] According to some embodiments of this utility model, the clamping assembly further includes a second locking block, wherein the first locking block is disposed at the tail of the base and the second locking block is disposed at the head of the base. The first locking block and the second locking block can more firmly clamp the electronic device, preventing it from shifting due to any external force or machine operation during the film application process. The two locking blocks can distribute the clamping force, avoiding damage to the electronic device caused by excessive force on a single point.
[0010] According to some embodiments of this utility model, the first locking block includes two opposing first guide grooves, which are inclined at an angle to one end of the electronic device. The second locking block includes two opposing second guide grooves, which are inclined at an angle to the other end of the electronic device. The inclined guide groove design allows the electronic device to slide naturally along the guide grooves to the center of the clamp assembly when it is placed in. This self-positioning mechanism reduces the need for manual adjustment by the operator, ensuring that the electronic device is in the optimal position each time the film is applied.
[0011] According to some embodiments of this utility model, the reset component is a tension spring. Tension springs are respectively provided on both sides of the first locking block. One end of each tension spring is fixed to the head of the base, and the other end is connected to the first locking block. The continuous elastic force provided by the tension spring ensures that the first locking block applies a stable clamping force to the electronic device, maintaining a good clamping effect even after long-term operation or multiple uses, thus guaranteeing stability during the film application process. The rapid response characteristic of the tension spring allows the first locking block to complete the reset action in a short time, accelerating the entire film application process and helping to improve the overall efficiency of the production line.
[0012] According to some embodiments of this utility model, a first rack and a second rack are respectively provided on both sides of the base. The first rack and the second rack extend along the movement direction of the exhaust mechanism. The power component includes a transmission motor and a coaxially arranged driven gear, a first traveling wheel, and a second traveling wheel. The transmission motor is connected to the driven gear. The first traveling wheel meshes with the first rack, and the second traveling wheel meshes with the second rack. This allows for precise movement of the exhaust mechanism along a predetermined path, ensuring that the exhaust roller can accurately run along the surface of the electronic device, thereby guaranteeing the effective removal of air bubbles during the film application process. Using a rack and pinion transmission reduces noise generated during the operation of the power component and provides high-precision movement control.
[0013] According to some embodiments of this utility model, a first baffle is provided on the side of the first rack away from the base, and the height of the first baffle is higher than the height of the first rack. Similarly, a second baffle is provided on the side of the second rack away from the base, and the height of the second baffle is higher than the height of the second rack. The first and second baffles effectively prevent dust, debris, and other foreign objects from entering the gear and rack transmission system, avoiding interference with the normal meshing of the gears and rack, thereby reducing the probability of mechanical failures and extending the service life of the transmission system. The baffles also provide a degree of sound insulation, especially when made of sound-absorbing materials, further reducing the outward transmission of noise generated during transmission and creating a quieter working environment. The presence of the baffles provides a physical barrier for operators, reducing the risk of accidental contact with high-speed rotating gears and racks and improving equipment safety.
[0014] According to some embodiments of this utility model, the base is provided with a positioning component, which includes a first positioning block, a second positioning block, and a third positioning block. The first positioning block is located at the front of the base, and the second positioning block is located at the rear of the base. The protective film is movably snapped into the positioning component. The design of the three positioning blocks provides stable support points, ensuring that the protective film remains stationary throughout the application process. Even with slight external forces or vibrations, the protective film will not shift, improving the success rate and quality of application. The movable snap-fit design simplifies the installation and replacement process of the protective film; the user simply places the protective film gently into the positioning component, and it automatically snaps into the correct position, reducing complex adjustment steps and improving work efficiency.
[0015] According to some embodiments of this utility model, the height of the second positioning block and the third positioning block relative to the base is higher than the height of the first positioning block relative to the base, and the protective film forms an inclined state with a lower front and a higher rear. The inclined protective film facilitates the flow of air from the lower end (front end) to the higher end (rear end), promotes the exhaust process by utilizing gravity, reduces the possibility of air bubble residue, and ensures the quality of film application. With the protective film in an inclined state, the first positioning block can provide a more stable clamping force at a lower position, ensuring that the protective film will not shift during the entire film application process, thus enhancing the stability of the fixation.
[0016] According to some embodiments of this utility model, the protective film and the positioning component are connected by an interference fit. The interference fit ensures a tight and gapless connection between the protective film and the positioning component. This high-precision fixing method prevents any displacement or slippage of the protective film during application, ensuring the accuracy of the film's position.
[0017] According to some embodiments of this utility model, the top of the first positioning block is provided with a folding portion, which is adapted to hold the protective film in place. Because the folding portion can better hold the protective film in place, it reduces the possibility of loosening or wrinkling at the edges of the protective film, and helps the air venting roller to expel air more effectively, thereby improving the overall quality and aesthetics of the film application.

[0028] Reference Figures 1 to 3 An automatic film applicator for applying protective films to electronic devices, comprising:
[0029] Base 100;
[0030] A clamping assembly is mounted on the base 100. The clamping assembly is provided with a first locking block 210, which is movably connected to the base 100. The first locking block 210 is connected to a reset member to limit the electronic device 200.
[0031] An exhaust mechanism 110 is connected to the base 100. The exhaust mechanism 110 includes a power component and a movable support 105. The power component is used to drive the movable support 105 to move above the electronic device 200. An exhaust roller 260 is provided on the bottom surface of the movable support 105. The exhaust roller 260 is used to compress the protective film 160 on the electronic device 200 to expel the air between the protective film 160 and the electronic device 200.
[0032] The design of the clamping assembly and the first locking block 210 securely limits the position of the electronic device 200, ensuring that the device will not shift during the film application process, thereby improving the accuracy of the film application. The exhaust roller 260 in the exhaust mechanism 110 can move between the protective film 160 and the electronic device 200, effectively compressing and expelling the air between them, significantly reducing the possibility of air bubbles after film application and ensuring the quality of the film application. The automated operation of the power component driving the moving support 105 and the exhaust roller 260 not only improves work efficiency but also reduces the errors that may be caused by manual operation, making the film application process more stable and reliable. The first locking block 210 is connected to a reset component, which can automatically return to the initial state after film application or position adjustment, facilitating the next operation and simplifying the operation process. Using this machine for film application can achieve higher quality protective film 160 coverage, extend the service life of the electronic device 200, and avoid problems that may be encountered when applying film manually, such as dust ingress or hand tremors leading to film application failure.
[0033] The clamping assembly also includes a second locking block 220. The first locking block 210 is located at the rear of the base 100, and the second locking block 220 is located at the front of the base 100. The first locking block 210 and the second locking block 220 can more firmly clamp the electronic device 200, preventing it from shifting due to any external force or machine operation during the film application process. The two locking blocks can distribute the clamping force, avoiding damage to the electronic device 200 due to excessive force on a single point.
[0034] The first locking block 210 includes two opposing first guide grooves, which are inclined at one end of the electronic device 200. The second locking block 220 includes two opposing second guide grooves, which are inclined at the other end of the electronic device 200. The inclined guide groove design allows the electronic device 200 to slide naturally along the guide grooves to the center of the clamp assembly when it is inserted. This self-positioning mechanism reduces the need for manual adjustment by the operator, ensuring that the electronic device 200 is in the optimal position each time the film is applied.
[0035] The reset element is a tension spring. Tension springs are provided on both sides of the first locking block 210. One end of the tension spring is fixed to the head of the base 100, and the other end is connected to the first locking block 210. The continuous elastic force provided by the tension spring ensures that the first locking block 210 applies a stable clamping force to the electronic device 200. Even after long-term operation or multiple uses, it can still maintain a good clamping effect, ensuring stability during the film application process. The rapid response characteristics of the tension spring allow the first locking block 210 to complete the reset action in a short time, speeding up the entire film application process and helping to improve the overall efficiency of the production line.
[0036] A first rack 120 and a second rack 130 are respectively provided on both sides of the base 100. The first rack 120 and the second rack 130 extend along the movement direction of the exhaust mechanism 110. The power component includes a drive motor and a coaxial driven gear 230, a first traveling wheel 240 and a second traveling wheel 250. The drive motor is connected to the driven gear 230. The first traveling wheel 240 meshes with the first rack 120, and the second traveling wheel 250 meshes with the second rack 130. This allows for precise movement of the exhaust mechanism 110 along a predetermined path, ensuring that the exhaust roller 260 runs accurately along the surface of the electronic device 200, thereby guaranteeing the effective removal of air bubbles during the film application process. Using a rack and pinion transmission reduces noise generated during the operation of the power component and provides high-precision movement control.
[0037] A first baffle 140 is provided on the side of the first rack 120 away from the base 100, and the height of the first baffle 140 is higher than the height of the first rack 120. A second baffle 150 is provided on the side of the second rack 130 away from the base 100, and the height of the second baffle 150 is higher than the height of the second rack 130. The first baffle 140 and the second baffle 150 can effectively prevent dust, debris and other foreign objects from entering the gear and rack transmission system, avoiding these foreign objects from affecting the normal meshing of the gears and racks, thereby reducing the probability of mechanical failure and extending the service life of the transmission system. The baffles can also play a role in sound insulation to a certain extent, especially when they are made of sound-absorbing materials, which can further reduce the outward transmission of noise generated during transmission, creating a quieter working environment. The presence of the baffles provides a physical barrier for operators, reducing the risk of accidental contact with high-speed rotating gears and racks, and improving the safety of the equipment.
[0038] The second positioning block 180 and the third positioning block 190 are at a higher height relative to the base 100 than the first positioning block 170 is relative to the base 100, resulting in a tilted state where the protective film 160 is lower at the front and higher at the back. This tilted protective film 160 facilitates airflow from the lower end (front) to the higher end (rear), using gravity to promote the venting process, reducing the possibility of air bubble residue, and ensuring the quality of the film application. With the protective film 160 tilted, the first positioning block 170 can provide a more stable clamping force at a lower position, ensuring that the protective film 160 does not shift during the entire application process, thus enhancing the stability of the fixation. If liquid is present during the application process, the tilted protective film 160 helps this liquid flow to the lower end and be collected or drained, preventing liquid stagnation in the working area from affecting the film application quality. By setting the second positioning block 180 and the third positioning block 190 to be higher than the first positioning block 170 relative to the base 100, the protective film 160 forms an inclined state with a lower front and a higher rear. This not only optimizes the working performance of the automatic film applicator and improves the film application quality and efficiency, but also provides users with a more convenient operating experience. This design takes into account the influence of physical characteristics on the film application process and is an effective means to improve equipment functionality and user experience. The base 100 is equipped with a positioning assembly, which includes the first positioning block 170, the second positioning block 180, and the third positioning block 190. The first positioning block 170 is located at the front of the base 100, and the second positioning blocks 180 and 190 are located at the rear of the base 100. The protective film 160 is movably snapped into the positioning assembly. The design of the three positioning blocks provides stable support points, allowing the protective film 160 to remain stationary throughout the entire film application process. Even with slight external force or vibration, the protective film 160 can be ensured not to shift, improving the success rate and quality of film application. The active snap-fit design simplifies the installation and replacement process of the protective film 160. Users only need to gently place the protective film 160 into the positioning component, and it will automatically snap into the correct position, reducing complicated adjustment steps and improving work efficiency.
[0039] The protective film 160 is connected to the positioning component via an interference fit. This interference fit ensures a tight, gapless connection between the protective film 160 and the positioning component. This high-precision fixing method prevents any displacement or slippage of the protective film 160 during application, guaranteeing the accuracy of the film's position.
[0040] The top of the first positioning block 170 is provided with a folding part, which is suitable for securing the protective film 160. Because the folding part can better secure the protective film 160, it reduces the possibility of loosening or wrinkling at the edges of the protective film 160, and helps the air venting roller 260 to expel air more effectively, thereby improving the overall quality and aesthetics of the film application.
[0041] In this embodiment, an automatic film applicator is provided for applying protective films to electronic devices. Through a series of innovative designs, this machine ensures a high-precision, low-noise, easy-to-operate, and efficient film application process.
[0042] The protective film 160 is angled, with its tail higher than its head. This design utilizes gravity to help air escape between the protective film 160 and the electronic device 200, optimizing the air bubble removal effect during the film application process. A positioning assembly including a first positioning block 170, a second positioning block 180, and a third positioning block 190 is provided on the base 100. The first positioning block 170 is located at the head of the base 100, while the second and third positioning blocks 190 are located at the tail. The protective film 160 is connected to the positioning assembly via an interference fit, ensuring its stability during film application. Specifically, the first positioning block 170 has a folded portion at its top, suitable for securing the protective film 160, further enhancing the fixing effect. It is understood that the first positioning block 170, the second positioning block 180, and the third positioning block 190 are set with different shapes, and the protective film 160 also has corresponding openings in corresponding positions, enabling a foolproof design that allows operators to better distinguish the front and back of the protective film 160, improving the efficiency of film application.
[0043] The clamping assembly includes a first locking block 210 at the head of the base 100 and a second locking block 220 at the tail. Each locking block includes a first guide groove and a second guide groove that are opposite each other and inclined at both ends of the electronic device 200. This design enables automatic centering of the electronic device 200, ensuring precise alignment with the protective film 160. Tension springs are provided on both sides of the first locking block 210, one end of which is fixed to the head of the base 100, and the other end is connected to the first locking block 210. The continuous elastic force provided by the tension springs ensures that the first locking block 210 can automatically return to its initial position, simplifying the operation process.
[0044] The exhaust mechanism 110 is connected to the base 100 and includes a drive motor, a driven gear 230, a first traveling wheel 240, and a second traveling wheel 250 coaxially arranged. The drive motor drives the driven gear 230, which in turn drives the first traveling wheel 240 and the second traveling wheel 250 to move along the first rack 120 and the second rack 130. The first rack 120 and the second rack 130 extend along the direction of movement of the exhaust mechanism 110 and are arranged on both sides of the base 100, ensuring the precise movement of the exhaust mechanism 110 along a predetermined path. The first traveling wheel 240 meshes with the first rack 120, and the second traveling wheel 250 meshes with the second rack 130. To reduce noise, high-precision machined gears and racks are used, and appropriate lubrication is applied. In addition, a first baffle 140 and a second baffle 150, higher than the rack height, are provided on the side of the rack away from the base 100 to prevent foreign objects from entering and provide additional safety.
[0045] When applying the screen protector, the user simply pushes the electronic device 200 into the guide groove between the first locking block 210 and the second locking block 220. The device will then slide naturally to the center position, achieving automatic centering. The protective film 160 is inserted into the positioning assembly and securely fixed by the interference fit and the folding part. The folding part not only provides additional clamping force but also simplifies the installation and removal process. After startup, the drive motor drives the exhaust mechanism 110 to move along the rack, and the exhaust roller 260 presses against the protective film 160, effectively expelling air and reducing the risk of air bubble formation. After the screen protector is applied, the user pulls the first locking block 210 and uses the electronic device 200 to release it, allowing the user to easily remove the screen protector 200.
[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
