Description

Technical Field

[0001] This utility model relates to the field of screen protector technology, and in particular to a high-precision positioning screen protector with a linkage clamping mechanism, which is suitable for screen protector application to electronic devices such as mobile phones, watches, and tablets. Background Technology

[0002] In the consumer electronics field, screen protectors are common accessories for smartphones, tablets, and other devices, and their application accuracy directly affects the user experience. Traditional manual screen protector application relies on visual alignment, which is prone to problems such as misalignment and air bubbles, especially with curved or irregularly shaped screens, resulting in a low success rate. While existing screen protector application tools can improve positioning, they have significant drawbacks: early positioning frames or magnetic template structures were fixed and only compatible with specific device models, resulting in poor compatibility; mechanical clamping devices require manual adjustment of the clamping block spacing, which is cumbersome and the positioning accuracy is affected by human factors, and uneven clamping force can easily lead to device deformation; automated screen protector application equipment, while highly accurate, is expensive and bulky, making it difficult to popularize.

[0003] With the diversification of electronic device screen forms (such as full-screen and foldable screens) and the upgrading of protective film materials (such as tempered glass and UV adhesive films), the market has placed higher demands on the positioning accuracy, ease of operation, and compatibility of screen protector application tools. Existing technologies suffer from problems such as low adjustment efficiency due to a lack of linkage in the positioning mechanism, insufficient automation relying on manual operation, narrow equipment compatibility, and uneven film application, all of which urgently need to be addressed.

[0004] Therefore, this utility model provides a high-precision positioning film applicator with a linkage clamping mechanism. Through linkage clamping and automatic centering structure, the device can achieve rapid and accurate positioning. Combined with a uniform film pressing component, it improves the film application quality, effectively overcomes the defects of existing technology, and meets diverse film application needs. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-precision positioning film applicator with a linkage clamping mechanism. The linkage clamping and automatic centering structure realize the precise positioning of the device to be applicated, and the film pressing component ensures the uniform application of the protective film.

[0006] This invention provides a high-precision positioning screen protector with a linkage clamping mechanism, comprising a base, a film pressing assembly, and a centering positioning module. The centering positioning module is slidably mounted on one end of the base, centering the head of the device to be applied and securing the tail of the device to a pin at the other end of the base. The film pressing assembly presses the protective film onto the screen of the device. The centering positioning module centers the head of the device and secures the tail of the device to the pin, ensuring stable positioning of the device during the application process. The film pressing assembly presses the protective film onto the screen, ensuring an orderly application operation and improving the accuracy and stability of the application.

[0007] Further describing the aforementioned solution, the centering positioning module includes a centering block, a positioning slider, a left positioning block, and a right positioning block. The centering block slides back and forth in the first guide groove of the base via a first anti-disengagement buckle and a directional strip at its bottom. The positioning slider slides back and forth in the second guide groove of the centering block via a guide plate at its bottom, a second anti-disengagement buckle, and the second guide groove of the centering block. The bottom of both the left and right positioning blocks is provided with a third anti-disengagement buckle, a transverse guide strip, and a guide post. The left and right positioning blocks move left and right in the anti-disengagement through-hole and transverse guide groove on the positioning slider via the third anti-disengagement buckle and the transverse guide strip. The left and right positioning blocks move back and forth on the inclined groove of the centering block via the guide post below the transverse guide strip. By changing the relative position of the centering block and the positioning slider, the left and right positioning blocks can clamp and release the film-applying device.

[0008] Further describing the aforementioned solution, a centering block spring is provided between the centering block and the base, and a positioning slider spring is provided between the positioning slider and the base, thereby achieving automatic centering and fixing of the device to be applied. The centering block spring and the positioning slider spring enable automatic centering and fixing of the device to be applied. During use, after the device is placed in the base, the springs automatically adjust their positions to center the device, reducing manual adjustment steps, improving application efficiency, and further ensuring positioning accuracy.

[0009] Further description of the aforementioned solution: a positioning post is provided at one end of the tail plug near the base, and a hook is provided on the positioning slider. The film assembly is installed and fixed by the positioning post and the hook, which can accurately position the film assembly and ensure that the protective film can be accurately aligned with the screen of the device to be covered during the film application process, thereby improving the accuracy of the film application and avoiding the situation where the protective film is applied off-center.

[0010] Further description of the aforementioned solution: the centering positioning module is installed in the recessed part of the base, which can accommodate the mobile phone lens. A locking hole is provided at one end near the recessed part, and a locking strip is provided at the end of the centering block. The centering block can be locked into the locking hole by the locking strip.

[0011] Further description of the aforementioned scheme: the pressure film assembly includes a slider and a roller. The roller is rotatably mounted on the shaft hole of the slider. The slider is slidably mounted on guide rails on both sides of the base via abutting posts and abutting blocks. The ends of the guide rails are provided with notches for the abutting posts or abutting blocks of the slider to enter and exit.

[0012] Further describing the aforementioned solution, the centering block is provided with a handle, and the positioning slider is provided with a handle hole to allow the user to operate the centering block and the positioning slider. The rear end of the handle hole is an end positioning surface, which is used to position the head of the device to be coated. The handle on the centering block and the handle hole on the positioning slider facilitate manual operation of the centering block and the positioning slider by the user to perform clamping and releasing actions on the device. The end positioning surface at the rear end of the handle hole can accurately position the head of the device to be coated, further improving the accuracy of device positioning.

[0013] Further description of the aforementioned solution: the left and right positioning blocks fix the head of the film-applying device in a centered position via the centering post on the upper surface. This enhances the positioning accuracy of the device head and ensures that the device is centered in the left-right direction, thereby ensuring that the protective film can be accurately applied to the screen.

[0014] Further describing the aforementioned solution, the positioning post is higher than the hook, and the film pressing assembly moves from the hook towards the positioning post to compress the protective film. This height difference and direction of movement design allows for better air expulsion during the compression of the protective film, avoiding air bubble residue, improving the quality and effect of the film application, and ensuring a tighter and smoother fit between the protective film and the screen.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The linkage clamping mechanism enables the device to be coated with film to be automatically centered without manual adjustment, thus improving positioning efficiency and accuracy;

[0017] (2) The tail plug works with the centering positioning module to fix the two ends and the left and right sides of the equipment to ensure the stability of the film application process;

[0018] (3) The roller design of the film pressing assembly can evenly squeeze the protective film. The film assembly is set with the front high and the back low, which effectively eliminates air bubbles and improves the film application quality.

[0019] (4) It is compatible with different models of equipment, and is compatible with equipment of different lengths, widths and thicknesses with little difference. It has a wide range of applications and is easy to operate.

[0020] (5) The center block and the left and right positioning blocks are driven by a symmetrical inclined groove and guide post transmission structure. Combined with the elastic restoring force of the center block spring and the positioning slider spring, the automatic centering and clamping of the film-applying equipment is achieved without the need for manual adjustment of the clamping distance, and the positioning efficiency is improved by more than 50%.

[0021] (6) The figure-eight guide groove of the center block can control the lateral movement of the left and right positioning blocks. The figure-eight guide groove is long in the longitudinal direction and short in the lateral direction. It adopts the principle of lever saving force and uses a long stroke to exchange for a large force. Therefore, the center block can easily pull the left and right positioning blocks, but the left and right positioning blocks can hardly drive the center block to move. Even if the phone or the left and right positioning blocks are touched by the user, or the watch surface is cleaned, the phone will not be tilted, effectively ensuring accuracy and stability.

These drawings and descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0039] Please see Figures 1-19 As shown, this utility model discloses a high-precision positioning screen protector with a linkage clamping mechanism, including a base 1, a film pressing assembly, and a centering positioning module 2. The centering positioning module 2 is slidably installed at one end of the base 1 to center the head of the device to be covered and to make the tail of the device to be covered abut against the tail plug 16 at the other end of the base 1 and fix it thereto. The film pressing assembly squeezes the protective film 5 onto the screen of the device to be covered.

[0040] Among them, such as Figure 12As shown, the base 1, serving as the supporting foundation for the entire device, is made of high-strength engineering plastic or metal and has a long, strip-shaped plate structure. A recessed area is provided at the front end, and a tail positioning structure is integrated at the rear. Guide rails 14 extend from both sides for mounting the film-pressing assembly. A tail plug 16 is located at the center of the rear end of the base 1. Its shape precisely matches the charging interfaces of common electronic devices, such as Type-C and Lightning interfaces. This plug-in method mechanically positions the tail of the device to be coated, ensuring stable fixation of the device in the longitudinal direction. A positioning post 11 is located above the tail plug 16. This positioning post 11 is a cylindrical protrusion, slightly higher than the hook 221 mounted on the centrally positioned module 2. It is used to fix the film assembly and, in conjunction with the hook 221, achieves precise positioning of the film assembly, ensuring that the protective film 5 is aligned with the device screen in the longitudinal direction.

[0041] The recessed area at the front end of the base 1 is used to accommodate the head camera module of the device to be coated, preventing unstable placement due to lens protrusion and ensuring a tight fit between the device head and the end positioning surface 227 of the centering positioning module 2. The end of the base 1 has a locking hole 15 that engages with the locking strip 213 at the end of the centering block 21 in the centering positioning module 2, locking the initial position of the centering positioning module 2 and ensuring the module remains open when the user places the device. The guide rails 14 on both sides of the base 1 are elongated with notches 141 at the ends, allowing the film pressing assembly to enter and exit, facilitating quick loading, unloading, and smooth sliding. Furthermore, the bottom of the base 1 has spring hooks 17, and the tails of the centering block 21 and the positioning slider 22 also have spring hooks 17 for mounting the centering block spring 217 and the positioning slider spring 228, providing elastic restoring force for the centering positioning module 2 and ensuring automatic centering during device positioning.

[0042] like Figures 4-11 As shown, the centering positioning module 2 is installed on the sunken part 13 at the front end of the base 1. It is the core component for centering the head of the equipment. It consists of a centering block 21, a positioning slider 22, a left positioning block 23 and a right positioning block 24. The components are linked together by anti-disengagement, guide groove, inclined groove 212 and other structures to achieve automatic centering and clamping of the head of the equipment.

[0043] The centering block 21 is rectangular in shape, with symmetrical first anti-disengagement buckles 215 and directional strips 216 at its bottom. It is slidably connected to the first guide groove 12 at the front end of the base 1, so that the centering block 21 can only slide along the front-back direction of the base 1. A second guide groove 211 is opened in the middle of the centering block 21, which allows the guide structure at the bottom of the positioning slider 22 and the second anti-disengagement buckle 226 to slide, thereby realizing the front-back movement of the positioning slider 22 on the centering block 21. Inclined grooves 212 are machined on both sides of the centering block 21. The inclined grooves 212 cooperate with the guide posts 233 at the bottom of the left and right positioning blocks 24. When the centering block 21 slides, the guide posts 233 move along the inclined grooves 212, converting the longitudinal movement of the centering block 21 into the lateral movement of the left and right positioning blocks 24, realizing the synchronous and equidistant movement of the two. The top of the dividing block 21 is provided with a handle 214, which makes it easy for the user to manually pull the dividing block 21. The end clip 213 can be inserted into the clip hole 15 of the base 1 to lock the position of the dividing block 21, which facilitates the preparation operation before the equipment is placed.

[0044] The positioning slider 22 is connected to the longitudinal guide groove of the centering block 21 through the bottom guide structure and anti-disengagement buckle. A handle hole 225 is provided at the top, allowing the user to pull the positioning slider 22 back and forth along the centering block 21. The rear end of the positioning slider 22 is a flat end positioning surface 227, used to abut against the head of the film application equipment, cooperating with the tail plug 16 of the base 1 to achieve positioning at both ends of the equipment. The positioning slider 22 has a transverse guide groove 222 and an anti-disengagement through hole 223, which cooperate with the anti-disengagement buckle and transverse guide strip 232 at the bottom of the left and right positioning blocks 24, allowing the left and right positioning blocks 24 to slide in the left and right directions while limiting their vertical and forward / backward displacement, ensuring the stability of the positioning process.

[0045] The left positioning block 23 and the right positioning block 24 have a symmetrical structure. The anti-disengagement buckle at the bottom is embedded in the anti-disengagement through hole 223 of the positioning slider 22. The horizontal guide strip 232 is slidably connected to the horizontal guide groove 222 of the positioning slider 22 to ensure the smoothness of left and right movement. The guide post 233 is located below the horizontal guide strip 232 and is embedded in the inclined groove 212 of the centering block 21. When the centering block 21 or the positioning slider 22 slides, the guide post 233 moves along the inclined groove 212, driving the left and right positioning blocks 24 to move synchronously to the center or both sides, realizing the clamping or loosening of both sides of the film application device. The upper surface of the left and right positioning blocks 24 is provided with a centering post 234 to improve the positioning accuracy of the device in the left and right direction and ensure that the central axis of the device coincides with the central axis of the film application device.

[0046] The centering block spring 217 and the positioning slider spring 228 are respectively connected to the base 1 and the centering block 21, and to the positioning slider 22, providing a backward elastic pulling force. When the user pulls the centering block 21 forward, the spring is stretched and stores energy; after being released, the spring's restoring force drives the centering block 21 and the positioning slider 22 to slide backward, causing the left and right positioning blocks 24 to automatically clamp the head of the equipment, realizing an automatic centering function without manual adjustment, compatible with equipment of different widths.

[0047] like Figure 13 As shown, the film-pressing assembly consists of a slider 3 and rollers 31, mounted on guide rails 14 on both sides of the base 1. It is used to evenly press the protective film 5 onto the device screen, ensuring no air bubbles remain during the bonding process. The slider 3 is cuboid in shape, with abutment posts 303 and abutment blocks 302 on both sides, and is slidably connected to the guide rails 14 of the base 1. The rollers 31 are mounted via a rotating shaft. The rollers 31 are cylindrical structures made of rubber, with a smooth and elastic surface, allowing for 360-degree free rotation.

[0048] In use, the user can push the slider 3 back and forth along the guide rail 14, and the roller 31 rolls as the slider 3 moves, pressing the protective film 5 from one end of the screen to the other. Since the height of the positioning post 11 of the base 1 is higher than the hook 221 of the positioning slider 22, the film assembly is tilted, with the front lower than the back. When the slider 3 slides from the hook 221 towards the positioning post 11, the rolling pressure of the roller 31 causes the protective film 5 to gradually adhere to the screen, and air is expelled from the center of the screen to the edge along the tilt direction, effectively preventing air bubbles. The notch 141 at the end of the guide rail 14 allows the slider 3's abutment structure to disengage, facilitating quick loading and unloading of the film-pressing assembly before and after film application, improving operational convenience. The elastic surface of the roller 31 can adapt to the curvature of curved screens, ensuring a tight fit at the edges, especially suitable for applying hard protective films 5 such as tempered glass and UV adhesive films.

[0049] The following is a detailed operation process using screen protector application on a mobile phone 4 as an example:

[0050] Preparation stage: such as Figure 17 As shown, first flip the slider 3 and roller 31, and the abutment block 302 of the slider 3 rotates out from the notch 141 of the guide rail 14, which facilitates subsequent operations; the user pulls the handle 214 of the centering block 21 forward until the locking strip 213 at the end of the centering block 21 engages with the locking hole 15 of the base 1, and the locking strip 213 lifts the slider 3 into the air, as shown. Figure 17 As shown, at this time, the center block spring 217 and the positioning slider spring 228 are stretched, and the left and right positioning blocks 24 open to both sides due to the sliding of the guide post 233 in the inclined groove 212, forming a space for placing the equipment.

[0051] Equipment placement: such as Figure 14As shown, insert the charging port at the rear of the phone 4 into the tail plug 16 of the base 1 to ensure accurate positioning of the tail; place the camera module on the back of the phone 4 into the recessed part 13 at the front of the base 1 to achieve tail positioning.

[0052] Automatic clamping: such as Figure 17 , 18 As shown, the slider 3 is pressed down, and the slider 3 presses against the locking strip 213 of the centering block 21, causing it to disengage from the locking hole 15. Under the action of the spring restoring force, the centering block 21 and the positioning slider 22 slide backward. The centering post 234 of the left and right positioning blocks 24 moves backward in the inclined groove 212 as the guide post 233 moves backward, and converges towards the center, clamping the two sides of the head of the phone 4, so that the central axis of the phone 4 is automatically aligned with the central axis of the screen protector. The end positioning surface 227 of the positioning slider 22 abuts against the head of the phone 4, completing the centering positioning. Figure 19 As shown.

[0053] Membrane module installation: such as Figure 15 As shown, the bottom positioning hole of the film assembly consisting of the protective film 5 and the positioning film 6 is fitted onto the positioning post 11 of the base 1, and the top hanging hole is hung on the hook 221 of the positioning slider 22. The height difference between the positioning post 11 and the hook 221 is used to make the film assembly naturally taut, ensuring that the protective film 5 is completely aligned with the screen of the mobile phone 4.

[0054] Screen protector application procedure: (e.g.) Figure 16 As shown, the slider 3 of the flip-up pressing assembly is flipped so that the abutment structure is engaged in the notch 141 of the guide rail 14 of the base 1. The slider 3 is pushed to slide slowly from the hook 221 to the positioning post 11. The roller 31 rolls and squeezes the protective film 5, expelling air from the top of the screen to the tail, until the protective film 5 is completely attached to the screen.

[0055] Disassembly and Reset: After the screen protector is applied, pull the center block 21 forward again, the left and right positioning blocks 24 will open, and the phone 4 can be removed; the slider 3 can be disengaged from the notch 141 of the guide rail 14.

[0056] In summary, this utility model, through the collaborative innovative design of the base 1, the centering positioning module 2, and the film pressing assembly, solves the problems of cumbersome positioning, insufficient accuracy, and poor compatibility of existing film application tools, and realizes automated, high-precision, and convenient film application operations, which has significant technical advantages and practical value.
