[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Example

[0028] Reference Figures 1-4 As shown, a screen coating device of this utility model includes:

[0029] Frame 1;

[0030] The fixture assembly 3 includes: an adjustment assembly and a first fixture plate 31. The first fixture plate 31 is connected to the end of the adjustment assembly. The adjustment assembly is disposed on the frame 1 and is used to adjust the distance between the first fixture plate 31 and the frame 1. The first side of the first fixture plate 31 has a groove for placing the screen 4 to be pasted.

[0031] The film coating assembly 2 includes: a rotating shaft assembly 21, a second fixture plate 24, and a suction cup 211 assembly. The second fixture plate 24 is connected to the rotating shaft assembly 21 and is rotatably connected to the frame through the rotating shaft assembly 21. The first side of the second fixture plate 24 is used to place the film to be applied 5. The second fixture plate 24 can be rotated until its plane is parallel to the plane of the first fixture plate 31. The input end of the suction cup 211 assembly can be connected to the film to be applied 5.

[0032] The screen coating device of this utility model fixes the screen 4 to be coated, such as the positioning mechanism of a mobile phone or tablet screen, through a fixture assembly 3. This assembly consists of an adjustment component and a first fixture plate 31. The adjustment component is located on the frame 1 and is used to adjust the vertical distance between the first fixture plate 31 and the frame 1. The first side of the first fixture plate 31 has a groove that perfectly matches the contour of the screen 4 to be coated, such as a rectangular groove corresponding to a rectangular screen. The depth of the groove matches the thickness of the screen 4 to be coated. Precise positioning of the screen 4 to be coated is achieved through the circumferential sidewall, preventing horizontal displacement during the coating process and ensuring the positional accuracy of subsequent coating operations. The film-coating assembly 2 is fixed to the frame 1 by a bracket, providing mounting support for the rotating shaft assembly 21. The rotating shaft assembly 21 is rotatably connected to the frame 1 via the bracket, and its rotation axis is parallel to the horizontal plane of the frame 1, allowing the second fixture plate 24 connected to the rotating shaft assembly 21 to rotate around this axis. The first side of the second fixture plate 24 is used to place the film to be applied 5. When it is rotated to the point where its plane is parallel to the first fixture plate 31, the film to be applied 5 is completely aligned with the screen to be applied, creating conditions for the bonding operation. The input end of the suction cup 211 assembly is connected to the film to be applied 5, and the film to be applied 5 is fixed by negative pressure adsorption, preventing displacement during rotation or bonding.

[0033] The operator first places the screen to be bonded into the groove of the first fixture plate 31. The height of the first fixture plate 31 is adjusted using the adjusting component to match the thickness of the screen 4 to be bonded. When the second fixture plate 24 is horizontal, the film to be bonded 5 covering it is directly opposite the screen on the first fixture plate 31. The film to be bonded 5 is placed on the first side of the second fixture plate 24, and the suction cup 211 assembly is activated to adhere and fix the film to be bonded 5. Then, the rotating shaft assembly 21 is rotated, moving the second fixture plate 24 from a position where the film can be easily lifted to a position parallel to and bonded with the first fixture plate 31. Finally, pressure is applied to the second fixture plate 24 to bond the film to be bonded to the screen. The dual positioning of the groove and the suction cup 211 ensures the alignment accuracy between the film to be bonded 5 and the screen; the adjusting component improves the adaptability of the device to screens of different sizes; and the rotating shaft 212 simplifies the transfer operation of the film to be bonded 5, reducing the difficulty of manual intervention.

[0034] Reference Figure 3 As shown, the rotating shaft assembly 21 includes: a bearing housing 214, bearings 216, a rotating shaft 212, and a rotating clamp 213. The bearings 216 are respectively sleeved on both ends of the rotating shaft 212. The bearings 216 are mounted on the frame 1 through the bearing housing 214. One end of the rotating clamp is fixedly clamped to the rotating shaft 212. The end of the rotating clamp 213 extends away from the first fixture plate 31 and is connected to the second fixture plate 24. The rotating clamp 213 has a clearance portion 215 adapted to the second fixture plate 24. The rotating shaft assembly 21 is the core of the rotational support for the second fixture plate 24, and consists of a bearing housing 214, a bearing 216, and a rotating clamp 213. The bearing 216 is a deep groove ball bearing 216, which is suitable for low-resistance rotation. The inner ring is fitted at both ends of the rotating shaft 212, and the rolling friction replaces the sliding friction, which significantly reduces the rotational resistance. The bearing housing 214 is fixed to the frame 1 by bolts. Its internal mounting hole is interference-fitted with the outer ring of the bearing 216 to ensure that the axis of the bearing 216 coincides with the preset rotation axis and avoids rotational deviation. The rotating clamp 213 is a split structure for easy installation and debugging. One end is fixed and clamped to the middle of the rotating shaft 212 by clamping bolts, and the other end extends away from the first fixture plate 31 to form an extension arm. The end of the extension arm is rigidly connected to the second fixture plate 24 by bolts. The avoidance part 215 prevents the rotating clamp 213 from interfering with the second fixture plate 24.

[0035] Reference Figures 1-2 As shown, when the second fixture plate 24 is rotated, the rotating clamp 213 rotates synchronously with the rotating shaft 212. The inner ring of the bearing 216 rotates with the rotating shaft 212, and the outer ring is fixed to the bearing seat 214, achieving smooth rotation without jamming. The extension arm design of the rotating clamp 213 provides sufficient rotation space for the second fixture plate 24, ensuring a stable rotation trajectory from the open position to the close position, and preventing the second fixture plate 24 from tilting due to space limitations.

[0036] The second fixture plate 24 is connected to the rotating shaft assembly 21 via an elastic component. This connection addresses the issue of rigid impact during the lamination process, such as crushing brittle screens or wrinkling the film. The elastic component includes a support body 23, a linear bearing 27, a guide shaft 28, and an elastic element 29. The support body 23 is connected to the rotating shaft assembly 21. The linear bearing 27 is embedded in the support body 23. The guide shaft 28 movably passes through the linear bearing 27 and its end is connected to the second fixture plate 24. The elastic element 29 is disposed between the support body 23 and the second fixture plate 24. The support body 23 is fixed to the rotating clamp 213, and its end face is provided with a mounting hole for the linear bearing 27. The linear bearing 27 is embedded in the support body 23, and its inner wall is treated with graphite inlay or grease to ensure the linear motion accuracy of the guide shaft 28. The guide shaft 28 is a cylindrical metal rod, one end of which is threaded to the second side of the second fixture plate 24, and the other end is movably inserted through the linear bearing 27 and connected to a limit head at the end to limit the movement trajectory of the second fixture plate 24 to a straight line. The elastic element 29 is a cylindrical helical compression spring, the elastic coefficient of which can be replaced as needed. It is sleeved on the outside of the guide shaft 28, and its two ends abut against the support body 23 and the second fixture plate 24 respectively.

[0037] When the film is pressed down, the second fixture plate 24 drives the guide shaft 28 to slide along the linear bearing 27 towards the support body 23. The spring is compressed and undergoes elastic deformation, converting external pressure into elastic potential energy and absorbing impact energy. After the pressure is removed, the spring's restoring force pushes the second fixture plate 24 back to its original position. The linear bearing 27 ensures that the guide shaft 28 does not deviate, guaranteeing the parallelism between the film to be applied 5 and the screen to be applied. The spring's buffering effect ensures that the pressure between the film and the screen is evenly distributed, avoiding defects caused by excessive local pressure. The elastic component effectively avoids the risk of rigid impact, protecting the screen to be applied and the film to be applied 5. The guiding function of the linear bearing 27 ensures the parallelism of the bonding process and improves the film bonding degree. The replaceability of the spring allows the device to adapt to screens of different materials, such as flexible screens and rigid screens. The frame 1 has a clearance opening 6 adapted to the first fixture plate 31, facilitating operation from below.

[0038] Reference Figure 3As shown, the frame 1 is equipped with a buffer 8. The second fixture plate 24 or the support 23 can abut against the end of the buffer 8, and when abutting, its plane is parallel to the horizontal plane. The support 23 is equipped with a handle 22. To ensure the positional stability of the second fixture plate 24 in the mating position, the frame 1 is equipped with a buffer 8, which is made of hydraulic, pneumatic, or rubber material, and its end is directly opposite the rotation path of the second fixture plate 24 or the support 23. When the second fixture plate 24 is rotated to the open position and its plane is parallel to the horizontal plane, its edge or the side of the support 23 will abut against the end of the buffer 8. The buffer 8 absorbs rotational inertia through oil, gas compression, or rubber deformation damping, which can control the final position of the second fixture plate 24 and avoid over-rotation or under-rotation due to inertia.

[0039] An ergonomic handle 22 is installed on the support body 23. The handle 22 is cylindrical and has a knurled anti-slip surface. The handle 22 is positioned on the outside of the rotation axis, using the lever principle to reduce the torque required for rotation. The operator can rotate the support body 23, the rotating shaft assembly 21, and the second fixture plate 24 by gripping the handle 22, without direct contact with the film to be applied 5, thus avoiding fingerprint contamination and improving operational safety and convenience. A foam board 25 is provided on the first side of the second fixture plate 24. The foam board 25 is fixed to the first side of the second fixture plate 24, and its shape is consistent with the second fixture plate 24, with a thickness of 1-5mm adjusted according to the hardness of the film to be applied 5. The foam board 25 is fixed with double-sided tape or bolts, and its surface is flat and burr-free to avoid scratching the film to be applied 5.

[0040] The elasticity of the foam board 25 can accommodate minor curling of the film 5 to be applied, such as warping of the film edges due to storage, ensuring a smooth surface for the film 5. During lamination, the foam board 25 evenly distributes the pressure of the second fixture plate 24 to the entire surface of the film 5, preventing bubbles or cracks caused by localized pressure concentration. Its softness can fill tiny gaps between the film and screen, such as minor scratches on the screen surface, improving adhesion. The cushioning effect of the foam board 25 reduces the risk of hard contact; the even pressure distribution improves the adhesion of the film and reduces the bubble rate; the soft material prevents scratches on the surface of the film 5, protecting the product's appearance.

[0041] The suction cup 211 assembly is disposed on the first side of the second fixture plate 24. The foam plate 25 has a receiving groove adapted to the suction cup 211 assembly. A negative pressure tube 210 is connected to the second side of the second fixture plate 24. The second fixture plate 24 has a negative pressure channel. The suction cup 211 assembly and the negative pressure tube 210 are connected through the negative pressure channel. The suction cup 211 assembly consists of multiple silicone suction cups 211, such as four or six, evenly distributed at the four corners of the film to be applied 5. The adsorption surface of the suction cup 211 is not lower than that of the foam plate 25. Therefore, the foam plate 25 has a receiving groove adapted to the contour of the suction cup 211, and the depth is adapted to the thickness of the suction cup 211 to ensure that the suction cup 211 directly contacts the film to be applied 5. At the same time, the rest of the foam plate 25 is adhered to the film to be applied 5.

[0042] The second fixture plate 24 has a negative pressure pipe 210 connected to its second side, which connects to an external vacuum pump or negative pressure generator. An internal negative pressure channel is provided: one end of the channel connects to the suction port of the suction cup 211, and the other end connects to the interface of the negative pressure pipe 210, forming an airflow path between the negative pressure source, the negative pressure pipe 210, the negative pressure channel, and the suction cup 211. When the negative pressure source is activated, the air pressure inside the suction cup 211 is lower than the external pressure, and atmospheric pressure tightly adheres the film 5 to be applied to the second fixture plate 24. The negative pressure pipe 210 is a flexible hose or corrugated pipe to avoid interfering with the rotation of the second fixture plate 24.

[0043] The receiving groove provides clearance for the suction cups 211, preventing them from obstructing the foam board 25 and lifting the film 5 to be applied. The inner diameter of the negative pressure channel is designed according to the number of suction cups 211 to ensure that each suction cup 211 receives sufficient adsorption force. The elastic material of the silicone suction cups 211 ensures airtightness during adsorption, preventing negative pressure leakage. Negative pressure adsorption achieves zero displacement fixation of the film 5 to be applied, ensuring the alignment accuracy of the film and screen. The receiving groove design allows the foam board 25 and the suction cups 211 to work together, retaining the buffer function without affecting the fixation effect.

[0044] The area of ​​the foam board 25 is larger than the area of ​​the screen 4 to be applied. A foam block 26 is provided on the outside of the screen 4. The first fixture plate 31 has a buffer groove adapted to the foam block 26. To enhance edge adhesion and depth buffering, the area of ​​the foam board 25 is larger than the screen to be applied. Outside the area covered by the film 5, the foam board 25 is integrally formed or bonded with the foam block 26, which can be rectangular, circular, or L-shaped. A buffer groove is provided around the groove of the first fixture plate 31, with a shape consistent with the foam block 26 and a depth adapted to the thickness of the foam block 26.

[0045] When the film is pressed down, the foam block 26 gradually embeds into the buffer groove, and the elastic deformation of the foam further absorbs the impact energy; the side wall of the buffer groove restricts the movement trajectory of the foam block 26 to prevent it from deviating; the large area of ​​the foam board 25 allows the edge of the film to be applied 5 to be covered by foam, ensuring uniform edge pressure and avoiding edge curling defects; the depth of the buffer groove prevents the foam block 26 from being over-compressed and extends the service life of the foam board 25.

[0046] The combination of foam block 26 and buffer groove enhances the deep buffering capacity and protects the corners of the screen to be attached; the larger area foam board 25 solves the edge adhesion problem; the limiting function of the buffer groove prevents the foam block 26 from deforming and failing, ensuring long-term stability.

[0047] The adjustment assembly is configured as multiple adjustment studs 32, each with an external thread at its end. The frame 1 has a positioning groove adapted to the adjustment studs 32, and the first fixture plate 31 has a threaded groove adapted to the adjustment studs 32. The adjustment assembly consists of four adjustment studs 32, distributed at the four corners of the first fixture plate 31, with external threads at their ends, such as M8 or M10. The frame 1 has a positioning groove with a diameter slightly larger than the outer diameter of the stud, which engages and restricts the horizontal position of the stud. The first fixture plate 31 has a threaded groove adapted to the external thread of the stud, with a depth greater than the thread length of the stud, ensuring that the stud can rotate freely.

[0048] Rotating the adjusting stud 32 converts the rotational motion into linear motion through the threaded engagement, controlling the height of the adjusting stud 32 protruding from the first fixture plate 31; multiple studs are evenly distributed to ensure that the first fixture plate 31 is horizontal, avoiding tilting that could cause misalignment of the membrane and screen; the positioning groove prevents the studs from shifting during rotation, ensuring adjustment accuracy.

[0049] The adjusting stud 32 enables precise adjustment of the height of the first fixture plate 31, adapting to screens of different thicknesses to be bonded, such as the thickness difference of mobile phone screens; the coordinated adjustment of multiple studs ensures levelness and improves bonding accuracy; the positioning groove's limiting function prevents loosening during the adjustment process and ensures the repeatability of the device.

[0050] In this embodiment, the frame 1 is equipped with multiple film-coating components 2 and detection components, such as three sets, to improve film-coating efficiency. A position sensor 9 is installed between the frame 1 and the support 23. The frame 1 is equipped with a testing machine, and a photoelectric sensor is installed on one side of the first fixture plate 31. To achieve automated detection, the position sensor 9 is installed between the frame 1 and the support 23. When the support 23 is rotated to the open position, the sensor detects that the second fixture plate 24 is in place, and film is applied to the second fixture plate 24. The photoelectric sensor at the first fixture plate 31 is used to detect whether there is a screen 4 to be applied on the first fixture plate 31. The testing machine is used to detect the screen after film application and is equipped with an interface for detection. The testing machine adopts the existing technology.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
