[0002] Tempered glass screen protectors, as a type of mobile phone protective film, possess excellent wear resistance and are extremely hard, thus providing excellent protection for the phone screen. Tempered glass is actually a type of prestressed glass. To improve the glass's strength, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external forces, this surface stress is first offset, thereby increasing its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts. Tempered glass screen protectors offer a high level of security protection for mobile phone screens. Applying a protective film is a crucial step in the tempered glass screen protector manufacturing process, primarily involving attaching a protective film to the tempered glass to provide dust protection.

[0003] Existing microcrystalline tempered glass film lamination equipment requires precise alignment of the protective film and the microcrystalline tempered glass film before the lamination process can be completed. This requires high alignment accuracy, which results in a lot of time and effort spent on alignment, seriously affecting the efficiency of microcrystalline tempered glass film lamination and hindering actual production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example: Reference Figure 1-5 The device shown is a laminating apparatus for processing microcrystalline tempered glass film, comprising a U-shaped base 1. Two first electric push rods 2 are mounted on the top of the U-shaped base 1. A support plate 3 is fixedly mounted on the output end of the two first electric push rods 2. A second electric push rod 4 is mounted on the top of the support plate 3. A carrier plate 5 is fixedly mounted on the output end of the second electric push rod 4. A cutter 6 is fixedly mounted on the bottom of the carrier plate 5. Two rotating rods 7 are rotatably connected to the support plate 3 via bearings. A take-up roller 8 is fixed to the other end of one rotating rod 7, and the other rotating rod 7 is fixed to... A feed roller 9 is fixed, and a protective film is provided between the take-up roller 8 and the feed roller 9. The feed roller 9 is used to release the protective film, and the take-up roller 8 is used to take up the cut protective film tail material. The cutter 6 is located above the protective film. A drive motor 10 is provided on the support plate 3, and the take-up roller 8 is driven by the drive motor 10. A base 11 is fixed on the U-shaped seat 1, and the base 11 is located below the protective film. A roller pressing assembly is provided on the support plate 3, and the roller pressing assembly is used for auxiliary bonding of the protective film on the microcrystalline tempered film.

[0023] The first electric push rods 2 push the tray 3 downward, so that the tray 3 drives the protective film between the take-up roller 8 and the unloading roller 9 to move down and attach to the surface of the microcrystalline tempered glass film placed on the base 11. The second electric push rod 4 pushes the cutter 6 to cut the protective film into a size that matches the microcrystalline tempered glass film. Then, the drive motor 10 is operated to pull the take-up roller 8 to take up the tail of the protective film and to release the new protective film from the unloading roller 9 so as to facilitate the lamination process of the next microcrystalline tempered glass film.

[0024] The base 11 has a slot 12 on its top and a storage cavity 13 inside. A through hole 15 is provided between the slot 12 and the storage cavity 13. A third electric push rod 14 is provided inside the storage cavity 13. A top rod 16 is fixedly installed at the output end of the third electric push rod 14. The top rod 16 slides with the inner wall of the through hole 15.

[0025] The third electric push rod 14 is used to push the push rod 16 into the slot 12 along the through hole 15, so that the push rod 16 lifts up the microcrystalline tempered glass film after the surface is coated, so that the worker can remove the microcrystalline tempered glass film.

[0026] The roller pressing assembly includes a first fixed block 17 and a pressure roller 22. The first fixed block 17 is fixedly installed on the support plate 3, and the pressure roller 22 is located above the protective film. A fourth electric push rod 18 is provided on the first fixed block 17. A carrier block 19 is fixedly installed at the output end of the fourth electric push rod 18. A spring 20 is fixed at the bottom of the carrier block 19. A second fixed block 21 is fixed at the bottom end of the spring 20. One end of the pressure roller 22 is rotatably connected to the second fixed block 21 through a bearing. A guide rod 23 is fixed on the upper surface of the second fixed block 21. The spring 20 is sleeved on the outside of the guide rod 23. A sliding groove for sliding the guide rod 23 is provided on the carrier block 19.

[0027] The pressure roller 22 is moved by the fourth electric push rod 18. With the help of the pressure given by the spring 20, the pressure roller 22 can press the protective film, so that the protective film and the microcrystalline tempered film are more tightly bonded.

[0028] The working principle of this practical application is as follows:

[0029] Take out the microcrystalline tempered glass film to be laminated and place it into the slot 12. The slot 12 limits its position. The thickness of the microcrystalline tempered glass film exceeds the depth of the slot 12. Control the two first electric push rods 2 to extend, so that the two first electric push rods 2 push the tray 3 to move down. The tray 3 pulls the protective film between the winding roller 8 and the unwinding roller 9 to move down, so that the protective film is attached to the microcrystalline tempered glass film. At this time, the pressure roller 22 will also move down with the tray 3. During the downward movement, the pressure roller 22 will apply pressure to the protective film with the help of the elastic force of the spring 20. As the fourth electric push rod 18 retracts, the pressure roller 22 can press the protective film tightly onto the microcrystalline tempered glass film, so that the two are more closely bonded.

[0030] Subsequently, the fourth electric push rod 18 drives the pressure roller 22 back to the starting position, and controls the second electric push rod 4 to extend, causing the second electric push rod 4 to push the cutter 6 downward to cut the protective film above the microcrystalline tempered glass film, so that the protective film that matches the microcrystalline tempered glass film is cut off, thus completing the surface lamination process of the microcrystalline tempered glass film. After that, the second electric push rod 4 retracts to pull the cutter 6 back to its original position, and the two first electric push rods 2 drive the support plate 3 to move upward and then back to its original position. The drive motor 10 is controlled to pull the winding roller 8 to wind up the tail of the protective film, causing the unloading roller 9 to release a new protective film. Then, the third electric push rod 14 is controlled to extend, causing the third electric push rod 14 to push the top rod 16 to push the surface-laminated microcrystalline tempered glass film away from the slot 12, so that the worker can remove the microcrystalline tempered glass film.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
