Description

Technical Field

[0001] This utility model relates to the field of mobile phone curved touch screen film covering technology, and in particular to a mobile phone curved touch screen film covering multiple pressing device. Background Technology

[0002] With the continuous development of smartphone technology, curved touchscreens have become a new favorite among users. They not only enhance the visual experience but also provide a better user experience. However, the use of curved screens has also brought a series of problems, especially in terms of screen protection and high-frequency touch control. Curved touchscreen protectors are an important accessory for protecting smartphone screens. Their function is not only to prevent scratches and drops but also to maintain sensitivity when users touch the screen frequently.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: When staff apply screen protectors to mobile phones, if the phone is placed on a table without effective cleaning, impurities such as dust, grease, fingerprints, and fine hairs on the screen surface can create tiny gaps between the screen protector and the screen, resulting in air bubbles that are difficult to eliminate after application. These air bubbles not only affect the aesthetics of the screen protector but may also expand during daily use, reducing the sensitivity and accuracy of the touchscreen. In addition, grease and fingerprints severely weaken the adhesion between the screen protector and the screen, making the protector prone to edge lifting, partial detachment, and other poor adhesion problems, greatly shortening the effective lifespan of the screen protector and potentially requiring reapplication in a short period of time. Therefore, to address the above problems, a multi-press device for applying curved touchscreen protectors to mobile phones is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where, when workers apply film to mobile phones, the screen surface is contaminated with dust, grease, fingerprints, and fine hairs without proper cleaning. Dust particles can create tiny gaps between the screen protector and the screen, leading to persistent air bubbles after application. This invention provides a multiple-press device for applying curved touchscreen film to mobile phones.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mobile phone curved touchscreen film covering multiple pressing device, including a pressing device body, a pressing frame installed on the inner surface of the pressing device body, a connecting block fixedly connected to the surface of the pressing frame, a U-shaped frame fixedly connected to the surface of the connecting block, round rods fixedly connected to both sides of the U-shaped frame, a sliding plate slidably connected to the arc surface of the round rods, and a cleaning pad fixedly connected to the side of the two sliding plates that are close to each other.

[0006] The aforementioned components achieve the following effect: they clean the phone screen, preventing the accumulation of dust, grease, fingerprints, and fine hairs on the screen surface when staff place the phone on a table before effective cleaning. Dust particles can create tiny gaps between the screen protector and the screen, leading to persistent air bubbles after application. These bubbles not only affect the aesthetics of the screen protector but may also expand during daily use, reducing touchscreen sensitivity and accuracy. Furthermore, grease and fingerprints severely weaken the adhesion between the screen protector and the screen, causing issues such as edge lifting and partial detachment, significantly shortening the effective lifespan of the screen protector and potentially requiring reapplication in a short period.

[0007] Preferably, one end of the round rod is fixedly connected to an elliptical plate, a lead screw is threaded into the elliptical plate, and one end of the lead screw is fixedly connected to a washer.

[0008] The effect achieved by the above components is that the rotating screw rotates inside the elliptical plate, and the screw drives the pad to move, so that the staff can disassemble and replace the cleaning pad regularly to maintain the cleaning pad's efficient cleaning power.

[0009] Preferably, a plug rod is slidably inserted into the U-shaped frame, one end of the plug rod is fixedly connected to a connecting rod, the other end of the plug rod is fixedly connected to a mounting plate, and a spring is sleeved on the arc surface of the plug rod, with both ends of the spring fixedly connected to the mounting plate and the U-shaped frame, respectively.

[0010] The effect achieved by the above components is that the spring force drives the insert rod to always point downward within the U-shaped frame, and the insert rod keeps the cleaning pad in close contact with the mobile phone screen.

[0011] Preferably, two guide plates are fixedly connected to the surface of the U-shaped frame.

[0012] The effect achieved by the above components is that by setting up a guide plate, the slide plate is pushed to slide on the surface of the guide plate, so that the staff can quickly install the cleaning pad, thus improving the convenience of the device.

[0013] Preferably, a handle is fixedly connected to the end of the lead screw away from the washer.

[0014] The effect achieved by the above components is that rotating the handle drives the lead screw to rotate inside the elliptical plate, and the lead screw drives the shim to move, so that the operator can stably rotate the lead screw and accurately control the position of the shim.

[0015] Preferably, the cleaning pad is made of silicone.

[0016] The effects achieved by the above components are as follows: the silicone sponge pad is soft and elastic, with good flexibility and resilience, and can adapt to mobile phone screens with different curvatures to a certain extent. At the same time, the silicone material itself has a certain degree of stickiness, which can absorb dust, hair and other small impurities on the screen.

[0017] Preferably, the connecting rod is cylindrical in shape.

[0018] The effect achieved by the above components is that by setting the connecting rod in the shape of a cylinder, a point forms a surface, which is always in contact with the cleaning pad, thus preventing uneven pressure.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model achieves the effect of cleaning the mobile phone screen, avoiding the problems that occur when staff place the phone on a table without effective cleaning during screen protector application. Dust, grease, fingerprints, and fine hairs on the screen surface can create tiny gaps between the screen protector and the screen, resulting in air bubbles that are difficult to eliminate after application. These air bubbles not only affect the aesthetics of the screen protector but may also expand during daily use, reducing the sensitivity and accuracy of the touchscreen. In addition, grease and fingerprints severely weaken the adhesion between the screen protector and the screen, making the protector prone to problems such as edge lifting and partial delamination, greatly shortening the effective lifespan of the screen protector and potentially requiring reapplication in a short period of time.

[0026] Reference Figure 1-4As shown, this utility model provides a technical solution: a mobile phone curved touch screen film covering multiple pressing device, including a pressing device body 1, a pressing frame 2 installed on the inner surface of the pressing device body 1, a connecting block 16 fixedly connected to the surface of the pressing frame 2, a U-shaped frame 3 fixedly connected to the surface of the connecting block 16, round rods 4 fixedly connected to both sides of the U-shaped frame 3, a sliding plate 5 slidably connected to the arc surface of the round rod 4, and a cleaning pad 6 fixedly connected to the side of the two sliding plates 5 that are close to each other. This achieves the effect of cleaning the phone screen, avoiding the problem of dust, grease, fingerprints, and fine hairs on the screen surface when staff place the phone on a table without effective cleaning. Dust particles can create tiny gaps between the screen protector and the screen, resulting in air bubbles that are difficult to eliminate after application. These air bubbles not only affect the appearance of the screen protector but may also expand during daily use, reducing the sensitivity and accuracy of the touchscreen. In addition, grease and fingerprints can severely weaken the adhesion between the screen protector and the screen, making the protector prone to problems such as edge lifting and partial delamination, greatly shortening the effective lifespan of the screen protector and even requiring reapplication in a short period of time. One end of the round rod 4 is fixedly connected to an oval plate 7, and a threaded rod 8 is inserted into the internal thread of the oval plate 7. One end of the threaded rod 8 is fixedly connected to a washer 10. The lead screw 8 rotates within the elliptical plate 7, causing the pad 10 to move. This allows for regular disassembly and replacement of the cleaning pad 6, maintaining its efficient cleaning power. A rod 12 is slidably inserted into the U-shaped frame 3. One end of the rod 12 is fixedly connected to a connecting rod 13, and the other end is fixedly connected to a mounting plate 14. A spring 15 is fitted onto the arc-shaped surface of the rod 12, with both ends of the spring 15 fixedly connected to the mounting plate 14 and the U-shaped frame 3, respectively. The spring 15's elasticity keeps the rod 12 pointing downwards within the U-shaped frame 3, ensuring the cleaning pad 6 remains firmly in contact with the phone screen. Two guide plates 11 are fixedly connected to the surface of the U-shaped frame 3. These guide plates 11 allow the sliding plate 5 to slide along their surface, facilitating quick installation of the cleaning pad 6 and improving the device's convenience. A handle 9 is fixedly connected to the end of the lead screw 8 furthest from the pad 10. Rotating the handle 9 causes the lead screw 8 to rotate within the elliptical plate 7. The lead screw 8 moves the pad 10, allowing the operator to stably rotate the lead screw 8 and precisely control the position of the pad 10. The cleaning pad 6 is made of silicone. Silicone sponge pads are soft and elastic, possessing good flexibility and resilience, and can adapt to mobile phone screens with varying curvatures to a certain extent. Silicone itself also has a certain degree of adhesion, which can absorb dust, hair, and other small impurities from the screen. The connecting rod 13 is cylindrical. By making the connecting rod 13 cylindrical, a single point forms a surface, always maintaining contact with the cleaning pad 6, preventing uneven pressure.

[0027] Working principle: When applying a screen protector to a mobile phone, the phone is first placed on the surface of the placement table and then moved under the pressing frame 2 via a slide rail. During this movement, it passes the cleaning pad 6. At this time, the spring force of the spring 15 drives the insertion rod 12 to always point downward within the U-shaped frame 3. The insertion rod 12 keeps the cleaning pad 6 firmly against the phone screen, and the cleaning pad 6 cleans the phone screen. When it is necessary to remove the cleaning pad 6, the handle 9 is turned to drive the lead screw 8 to rotate within the oval plate 7. The lead screw 8 drives the pad 10 to move until the pad 10 no longer contacts the sliding plate 5. Then, the sliding plate 5 is pulled to move, completing the removal and achieving the effect of cleaning the phone screen without hurting the operator's hands. When applying the screen protector, the staff places the phone on a table. Without proper cleaning, dust, grease, fingerprints, and fine hairs on the screen surface can create tiny gaps between the screen protector and the screen, resulting in persistent air bubbles. These bubbles not only affect the appearance of the screen protector but may also expand during daily use, reducing touchscreen sensitivity and accuracy. Furthermore, grease and fingerprints severely weaken the adhesion between the screen protector and the screen, making the protector prone to edge lifting, partial detachment, and other poor adhesion issues. This significantly shortens the effective lifespan of the screen protector and may even require reapplication in a short period.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
