Description

Technical Field

[0001] This utility model relates to the field of tempered glass film processing technology, and in particular to a film-coating device for processing tempered glass films for mobile phones. Background Technology

[0002] Tempered glass screen protectors are a new type of mobile phone screen protector launched in China in 2012. They are a high-end new product that provides the strongest protection for the screen.

[0003] For example, Chinese utility model patent application number 202122303190.2 discloses a film-coating device for processing tempered glass screen protectors for mobile phones, relating to the field of tempered glass screen protector processing technology. The device includes a body, a crossbeam fixedly mounted on the top surface of the body, an electric push rod fixedly mounted near the center of the top surface of the crossbeam, a material wheel mounted on the output end of the electric push rod, brackets A and B fixedly mounted on the top surface of the body, and transmission rods rotatably connected to the back of both brackets A and B. A motor is fixedly mounted on the surface of bracket A, and the output end of the motor is fixedly connected to the transmission rod. A conveyor belt is sleeved on the surface of the transmission rod, and a bending frame is fixedly mounted on the top surface of the body near the conveyor belt. This utility model, through the inclusion of a brush, can reduce the probability of dust residue during the tempered glass screen protector coating process, thereby improving the yield rate. Simultaneously, due to the tension of the spring, it can effectively adapt to tempered glass screen protectors of different thicknesses, making it highly practical.

[0004] While the aforementioned patent can apply a film to tempered glass screen protectors using a material roller, in practice, different phone models require different sizes of tempered glass screen protectors. The device lacks an auxiliary film application mechanism, and the material roller has a fixed width design. This means that when the roller's width exceeds the screen protector's width, excess material drips around the screen protector in areas that don't need film application. This requires subsequent cleaning by staff, which is time-consuming and labor-intensive. Utility Model Content

[0023] The coating mechanism includes an electric telescopic rod 23 and a water pump 24. The electric telescopic rod 23 is fixedly installed at the bottom of the screw sleeve 22. The telescopic end of the electric telescopic rod 23 is fixedly connected to a rectangular hollow plate 25. Several bristles 26 are provided on the rectangular hollow plate 25, and the bottom of the bristles 26 penetrates through the rectangular hollow plate 25 and extends to the outside of the rectangular hollow plate 25. The water pump 24 is fixedly installed at the top of the raw material box 9. The water outlet end of the water pump 24 is fixedly connected to a hose 27. The water pump 24's suction end is fixedly connected to the raw material box 9. The other end of the hose 27 is fixedly connected to the rectangular hollow plate 25. By using the lifting mechanism, the coating mechanism, the mold frame 14 and the mold frame 25 in combination, the height of the mold frame 14 can be adjusted by rotating the knob 19 to accommodate tempered glass films of different thicknesses. At the same time, by adjusting the distance between the brush bristles 26 and the tempered glass film, the coating thickness of the mobile phone tempered glass film is ensured. Thus, the device can adapt to the coating needs of various specifications of tempered glass films, improving the applicability of the device.

[0024] Working principle: When it is necessary to apply a tempered glass screen protector to a mobile phone, the staff first replaces the matching mold frame 1 4 and mold frame 2 15 according to the model of the tempered glass screen protector. When replacing mold frame 1 4, first pull out the pin 1 5 upwards, then insert mold frame 1 4 into the connecting rod 3 and insert the pin 1 5 back to complete the fixation. Mold frame 2 15 is installed on the snap-fit ​​frame 14 by snap-fit. After the mold is replaced, take out the corresponding model of absorbent paper 29 from the placement box 28 and fix it in mold frame 1 4, and put the tempered glass screen protector to be applied into mold frame 2 15. After the mold is installed, adjust the height of the brush 26 and the mold frame 4 according to the thickness of the tempered glass film and the required coating thickness. Rotate the threaded rod 17 by turning the knob 19, so that the threaded sleeve 18 drives the connecting rod 3 and the mold frame 4 to descend. Stop rotating when it descends to the predetermined height. Then start the electric telescopic rod 23. The telescopic end of the electric telescopic rod 23 drives the rectangular hollow plate 25 and the brush 26 to move down. After adjusting the brush 26 to the predetermined height, close the electric telescopic rod 23. After the preparation is completed, start the drive motor 10. The output of the drive motor 10 drives the active roller 12 to rotate. The active roller 12 drives the driven roller 11 to rotate through the conveyor belt 13, so that the mold frame 15 carries the tempered glass screen protector to be coated to the L-shaped plate 8. When the mold frame 4 and the mold frame 2 15 are aligned, turn off the drive motor 10. At this time, the upper surface of the tempered glass screen protector is level with the bottom of the mold frame 4.

[0025] During the lamination process, drive motor 20 and water pump 24 are started. The pump 24 draws lamination material from the material tank 9 and delivers it to the hose 27 and rectangular hollow plate 25 through the outlet of the pump 24. Finally, the material flows down the brush bristles 26. At the same time, drive motor 20 drives the reciprocating screw 21 to rotate, causing the screw sleeve 22 to drive the brush bristles 26 to reciprocate on the film surface, ensuring uniform lamination. During this process, any excess material that exceeds the width of the tempered glass film will be absorbed by the absorbent paper 29 in the mold frame 4, preventing the material from dripping onto the mold and the parts of the tempered glass film that do not need to be laminated.

[0026] When the mold frame 1 4 and the absorbent paper 29 inside it need to be replaced or cleaned, the pin 2 7 can be pulled upwards to release the lock of the rotating disk 2, and the rotating disk 2 can be rotated 180 degrees to make the spare mold frame 1 4 enter the working position. This allows the replaced mold frame 1 4 to be cleaned and the new absorbent paper 29 to be fixed without interrupting production, ensuring the continuity and efficiency of the lamination operation.

[0027] 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.
