[0002] The mobile phone double-sided adhesive hole cutting device is a device specifically used to create precise holes in the mobile phone double-sided adhesive. Its main uses are to meet multiple key requirements in mobile phone production, such as providing accurate and suitable fixed positions for the installation of various internal components of the mobile phone; ensuring that the mobile phone signal is not blocked and interfered by the double-sided adhesive during transmission; improving the heat dissipation effect of the mobile phone by cutting holes at corresponding positions to prevent heat accumulation from affecting performance; and at the same time, being able to perform precise hole processing according to the unique design requirements of the mobile phone, such as thin and light design, special structure, etc., so as to ensure the high-quality assembly and excellent performance of the mobile phone.

[0003] However, in actual mobile phone production, the size requirements for double-sided adhesive hole cutting may vary. If the size of the cutting edge of the device remains fixed, when cutting smaller holes, there may be a problem of excessive cutting range, resulting in material waste and inaccurate cut edges. When cutting larger holes, due to the too small cutting edge, multiple cutting operations may be required, which not only has low efficiency but may also cause the shape and size of the holes not to meet the requirements due to the cumulative error of multiple cuts.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figures 1 to 4 As shown, a double-sided adhesive hole cutting device for a mobile phone includes a mounting chamber 1, on which a transmission assembly 2 is arranged;

[0029] The transmission assembly 2 includes a fixed frame 212, on which a connecting plate 21 is provided, on which a connecting shaft 22 is fixedly connected, on which a stretching shell 25 is slidably connected, in which a second rotating shaft 27 is rotatably connected, on which a stretching block 28 is rotatably connected, on which a first rotating shaft 26 is rotatably connected, on which a sliding member 29 is rotatably connected at the bottom of the first rotating shaft 26, a blocking member 210 is slidably connected in the stretching shell 25, and on which a third connecting member 211 is fixedly connected;

[0030] In the utility model, the up and down movement of the first rotating shaft 26 is controlled by rotating the adjusting rod 34 by external force, thereby controlling the expansion and contraction of the extension shell 25, which can adapt to the cutting requirements of various sizes and enhance the versatility and practicality of the device. The up and down movement of the first rotating shaft 26 can drive the sliding member 29 to achieve precise adjustment of the cutting depth, so that the device can set the optimal cutting depth according to different double-sided tape materials and thicknesses, greatly improving the flexibility and accuracy of cutting. When the extension shell 25 expands outward, the blocking member 210 can timely block the gap at the bottom of the extension shell 25, effectively preventing debris from entering or cutting waste from leaking, thereby effectively ensuring the integrity and high quality of the cutting effect and solving the problem that the existing technology in the background technology cannot adjust the size of the cutter.

[0031] Further, such as Figures 1 to 4 As shown, the third connecting member 211 is fixedly connected to the second connecting member 24, and one end of the second connecting member 24 away from the second rotating shaft 27 is fixedly connected to the first connecting member 23, and the first connecting member 23 is fixedly connected to the adjusting rod 34. The second connecting member 24 is provided to connect the first connecting member 23. When in use, since the adjusting rod 34 is fixedly connected to the bottom of the first connecting member 23, the first connecting piece 35 is rotated by external force, so that the threaded rod 36 rotates, driving the adjusting rod 34 to slide up and down on the threaded rod 36.

[0032] A rotating shaft 38 is slidably connected to the adjusting rod 34. A threaded rod 36 is threadedly connected to one end of the adjusting rod 34 away from the first connecting member 23. By providing the threaded rod 36, it is convenient to adjust the height of the adjusting rod 34. By providing the rotating shaft 38, the adjusting rod 34 is limited to prevent the adjusting rod 34 from being driven to rotate;

[0033] A first connecting piece 35 is fixedly connected to the threaded rod 36. A fourth connecting member 37 is threadedly connected to one end of the threaded rod 36 away from the first connecting piece 35. A sliding frame 33 is slidably connected to the first connecting piece 35. The sliding frame 33 is fixedly connected to the installation bin 1. The rotating shaft 38 is rotatably connected to the installation bin 1. During the rotation of the threaded rod 36, the fourth connecting member 37 will be driven to move slightly until it is stuck at the bottom of the sliding frame 33, effectively preventing the adjusting rod 34 from falling off;

[0034] There is also a problem in the above solution that does not mention how to move the double-sided tape raw material. As Figures 1 to 2 shown, a discharge frame 31 is fixedly connected to one side of the installation bin 1 close to the fixed frame 212. A rotating roller 32 is rotatably connected in the discharge frame 31. A motor 3 is fixedly connected to the discharge frame 31. The motor 3 is fixedly connected to the rotating roller 32. There are two rotating rollers 32. During use, the main function of the rotating roller 32 is to drive the double-sided tape to move. The motor 3 can electrically rotate the rotating roller 32 to drive the material to move.

[0035] An electric telescopic rod 213 is fixedly connected to the fixed frame 212. The top of the electric telescopic rod 213 is fixedly connected to the connecting disk 21. By providing the electric telescopic rod 213, it is convenient to drive the connecting disk 21 and the connecting shaft 22 to move up and down.

[0036] Working principle:

[0037] As Figures 1-4 shown: During use, first insert the double-sided tape through the bottom of the stretching shell 25 and onto the rotating roller 32. Start the rotating roller 32 to make it rotate, so that the double-sided tape is driven to move. Then, start the electric telescopic rod 213 to drive the connecting disk 21 and the connecting shaft 22 to be pressed down in sequence. During this process, by externally rotating the first connecting piece 35, the adjusting rod 34 can be driven to move up and down, so that the first rotating shaft 26 can be driven to move up and down. When the stretching block 28 moves upward, it will squeeze the stretching shell 25 outward, realizing the expansion of the stretching shell 25. When the first rotating shaft 26 moves downward, the stretching shell 25 can be contracted inward. When the first rotating shaft 26 moves up and down, it will also drive the sliding member 29 to move up and down, realizing the adjustment of the cutting depth on the stretching shell 25. When the stretching shell 25 expands outward, the sealing member 210 will seal the gap at the bottom of the stretching shell 25 to avoid affecting the cutting effect.

[0038] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes in other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
