The operation is simple and convenient, which improves the applicability of the laminating device.

[0008] Furthermore, the surface of the rotating knob is provided with equidistant annular grooves for anti-slip.

[0009] Based on the above technical features, the equidistant annular grooves on the surface of the rotating knob increase the friction, making it easier for the user to rotate the screw to adjust the pitch, preventing hand slippage and improving the stability and accuracy of the operation.

[0010] Furthermore, the elastic clamping structure includes a square frame connected to both sides of the mounting plate and located at the front and rear sides of the screw, a clamping block is slidably arranged in the square frame, a spring is connected between the clamping block and the square frame away from one end of the screw, and an arc plate is connected to the other side of the clamping block through a connecting rod, and the arc plate is provided with a groove that engages with the screw.

[0011] Based on the above technical features, the spring can provide a certain elastic clamping force to ensure that the screw rod is stable after adjustment and will not move easily. The groove on the curved plate fits tightly with the screw rod, further enhancing stability.

[0012] Furthermore, front and rear guide grooves are provided under the handle, front and rear blocks are slidably provided in the front and rear guide grooves, elastic clips are connected to the front and rear blocks, and a rear pull block is connected to the rear side of the elastic clip.

[0013] Based on the above technical features, the design of the front and rear guide grooves, the front and rear blocks and the elastic clip can conveniently clamp one end of the flexible film sheet protective film to prevent it from loosening or shifting during the film application process.

[0014] Furthermore, the inlet of the through slot is arranged at the upper side of the rear surface of the rectangular strip, and the outlet is arranged at the front side of the lower surface of the rectangular strip.

[0015] Based on the above technical features, the direction of the flexible film sheet is made more reasonable, which is convenient for users to perform film sticking operations and reduces the jamming and distortion of the film sheet during the passing process.

[0016] Furthermore, a scraper is connected to the mounting plate, and the extended end of the scraper is rounded.

[0017] Based on the above technical features, the scraper can scrape the film sheet flat during the film application process, remove bubbles and wrinkles, and improve the flatness of the film application. The rounded corners of the extended end of the scraper can avoid scratching the screen of the electronic device.

[0018] Furthermore, a rubber sleeve is sleeved on the rear end of the handle.

[0019] Based on the above technical features, the rubber sleeve increases the comfort of holding and also plays an anti-slip role, making it easier for users to operate the fitting device and improve the accuracy and stability of the film.

[0020] Compared with the prior art, the present invention has the following advantages:

Its adjustable distance structure can drive the screw by turning the knob to make the slider slide on the slide rail, thereby adjusting the vertical rod spacing to adapt to electronic devices of different sizes. The rotating clamping cylinder can match the edges of devices of different shapes to ensure that the film sheet fits tightly. The universal through-slot design allows smooth laminating operations regardless of the size and shape of the film sheet. This makes it unnecessary to prepare multiple tools for different devices, greatly improving the convenience of use. Whether it is a mobile phone, tablet or other electronic device, it can easily cope with and meet various film laminating needs.

[0022] The device is excellent in preventing bubbles from forming during film application. The laminating pressing roller presses the film sheet evenly onto the screen under the guidance of the arc sheet, while the scraper can scrape the film sheet flat in time, remove possible bubbles and wrinkles, and ensure the flatness of the film. At the same time, the elastic clip and the rear pull block design can conveniently control the peeling speed of the protective film and reduce the contact area between the film sheet and the air. During the film application process, hooking the rear pull block with your fingers can ensure that the protective film is always in the right position, which does not hinder the film application and effectively prevents the generation of bubbles, thereby providing a perfect film application effect for electronic devices and improving the quality and efficiency of film application.

The vertical rod 5 is connected to the bottom of the slider 11. The cooperation between the slide rail 10 and the slider 11 and the adjustment of the screw 12 can achieve precise distance adjustment to meet the film pasting requirements of electronic devices of different sizes. The operation is simple and convenient, and the applicability of the pasting device is improved.

[0033] Combination Figure 7The vertical rod 5 is connected to the lower part of the distance adjustment structure, and a rotating clamping cylinder 6 is rotatably provided on the vertical rod 5. Both sides of the mounting plate 1 are connected with an elastic clamping structure for limiting the distance adjustment structure. The elastic clamping structure includes a square frame 15 connected to both sides of the mounting plate 1 and located at the front and rear sides of the screw rod 12. A clamping block 16 is slidably provided in the square frame 15. A spring 17 is connected between the clamping block 16 and the end of the square frame 15 away from the screw rod 12. The other side of the clamping block 16 is connected to an arc plate 18 through a connecting rod. The arc plate 18 is provided with a groove 19 engaged with the screw rod 12. The spring 17 can provide a certain elastic clamping force to ensure that the screw rod 12 is stable after adjustment and will not move easily. The groove 19 on the arc plate 18 is tightly engaged with the screw rod 12, further enhancing the stability.

[0034] Combination Figure 2 and Figure 3 The mounting plate 1 is connected to a rectangular strip 7 below, and a through slot 8 is provided in the rectangular strip 7 for the flexible film sheet to pass through. The entrance of the through slot 8 is located at the upper side of the rear of the rectangular strip 7, and the exit is located at the front side of the lower side of the rectangular strip 7, so that the direction of the flexible film sheet is more reasonable, which is convenient for users to perform film sticking operations and reduces the jamming and distortion of the film sheet during the passing process.

The design of the front and rear guide groove 20, the front and rear blocks 21 and the elastic clip 22 can conveniently clamp one end of the flexible film sheet protective film to prevent it from loosening or shifting during the film application process.

[0036] Working principle: First, make preparations, check whether the components of the laminating device, such as the mounting plate 1, laminating pressure rod 2, scraper 24, distance adjustment structure, elastic clamping structure, rectangular bar 7, handle 9, etc., are intact, ensure that the rotating clamping tube 6 rotates smoothly and there is no debris blocking the groove 8, and select the appropriate flexible film sheet according to the size of the electronic device. Then adjust the device, rotate the rotating knob 13 according to the size of the electronic device, and the equidistant annular grooves 14 on its surface increase the friction to prevent hand slippage and improve the operation stability. The rotating knob 13 drives the screw 12 to rotate, so that the screw 12 pushes the slider 11 to slide on the slide rail 10, thereby adjusting the distance between the vertical rods 5 to adapt to electronic devices of different sizes, so that the rotating clamping tube 6 clamps the two sides of the electronic device. After adjustment, the spring 17 in the elastic clamping structure pushes the clamping block 16, so that the groove 19 on the arc plate 18 engages with the screw 12 to ensure its stable position. Then place the film sheet, put the flexible film sheet into the entrance of the groove 8 on the upper back side of the rectangular strip 7 and move it forward along it, and pass it out from the front outlet on the lower side of the rectangular strip 7. Use the elastic clip 22 under the handle 9 to clamp one end of the dustproof protective film of the film sheet itself, and one end of itself is attached to the upper end of the screen of the electronic device. The elastic clip 22 can be easily operated by the rear pull block 23 to prevent the film sheet from loosening or shifting during the film application process. Holding the handle 9, align the laminating device with the electronic device screen to align the film sheet with the screen, and slowly push the laminating device so that the laminating pressing rod 2 presses the flexible film sheet onto the electronic device screen under the guidance of the arc sheet 3. During this process, the fingers always hook the rear pull block 23, so that the protective film of the flexible film sheet is always lower than the laminating point, which does not hinder the laminating process and has a certain dust-proof effect with a small contact area with the air. After the laminating is completed, check whether the film sheet is tightly attached. If there are bubbles or wrinkles, use the scraper 24 again to deal with them. The rounded corners of the extended end of the scraper 24 can avoid scratching the electronic device screen. In the above manner, the electronic device can be efficiently and accurately laminated, thereby improving the quality and efficiency of laminating.
