Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution: a hole-opening device for producing mobile phone diaphragms, comprising a hollow placement box 1 with an upper opening, the upper inner wall of the placement box 1 is fixedly connected to a diaphragm placement platform 3, a moving groove 2 is provided at the front end of the placement box 1, the lower inner wall of the moving groove 2 and the upper end of the diaphragm placement platform 3 are at the same horizontal line, the upper end of the diaphragm placement platform 3 is provided with two first moving grooves 4, the adjacent ends of the two first moving grooves 4 are connected to a plurality of second moving grooves 5, the interiors of the two first moving grooves 4 are slidably connected to sliders, the upper ends of the two sliders are fixedly connected to a first moving block 6, and the two The upper ends of the first moving blocks 6 are fixedly connected to the diaphragm fixing plates 7, the lower ends of the two diaphragm fixing plates 7 are connected to springs 8, the lower ends of the two springs 8 are connected to pressure plates 9, the two sliders are adapted to the sizes of the multiple second moving grooves 5, the upper end of the diaphragm placing table 3 is provided with a second moving block 13, the upper end of the second moving block 13 is fixedly connected to a steel wire soft rod 14, the lower end of the steel wire soft rod 14 is fixedly connected to a mechanical puncher 15, the upper ends of the two pressure plates 9 are fixedly connected to connecting rods 10, the two connecting rods 10 are respectively slidably connected to the inside of the two diaphragm fixing plates 7, and the slider is cross-shaped.

[0024] During operation, when punching holes in the diaphragm, the mobile phone diaphragm is placed on the upper end of the diaphragm placement table 3, and the height of the pressure plate 9 is raised. Since the slider slides inside the first movable groove 4, and the first movable groove 4 is connected to the second movable groove 5, the slider can slide inside the first movable groove 4 and the second movable groove 5, and can be placed at the position where the mobile phone diaphragm needs to be fixed. At this time, through the reaction force of the spring 8, the pressure plate 9 is driven to descend through the spring 8, and the collection diaphragm is simply fixed, and the position of the slider is limited. At this time, the mechanical puncher 15 can be driven to move at the same time by the steel wire soft rod 14. Since the steel wire soft rod 14 is corrugated, the length can be adjusted, and the hand can be punched through the mechanical puncher 15 The diaphragm of the machine is punched. The first movable block 6 can slide inside the first movable groove 4 and multiple second movable grooves 5, so that mobile phone diaphragms of different sizes can be fixed. The working principle of the mechanical puncher is to drive the rotary drill bit to rotate through the motor, and at the same time apply a certain pressure through the pressure foot to make the drill bit drill into the material surface and form a hole. During the drilling process, the punching machine automatically feeds to ensure the stability and accuracy of the drill bit during the drilling process. Before drilling, pretreatment of the material is also crucial. When punching, the punching position can be fixed with tape or glue to reduce displacement during the punching process. At the same time, a small hole can be pre-punched on the tile to reduce stress concentration during formal punching, thereby reducing the risk of tile cracking. For other materials, such as metal or plastic, corresponding pretreatment measures should also be taken according to their characteristics. In this application, the strength of fixing the diaphragm can be adjusted according to the material of the diaphragm, and the number of turns of the spring 8 can be adjusted, so that the diaphragm can be fixed during processing without causing damage to the diaphragm.

[0025] See also Figure 1-4 The utility model provides a technical solution: the left and right ends of the diaphragm placement table 3 are fixedly connected with connecting plates 17, and the far ends of the two connecting plates 17 are respectively in contact with the left and right inner walls of the placement box 1.

[0026] During operation, the connecting plates 17 are respectively fitted with the left and right inner walls of the placement box 1 , thereby blocking the waste materials punched in the placement box 1 and preventing them from entering the interior of the placement box 1 .

[0027] See also Figure 1-4 The utility model provides a technical solution: the upper ends of the two connecting rods 10 are fixedly connected with handles 11.

[0028] During operation, the handle 11 is fixedly connected to the connecting rod 10. When the pressing plate 9 needs to be moved, the height of the handle 11 is raised, and the connecting rod 10 can drive the pressing plate 9 to move at the same time.

[0029] See also Figure 1-4The utility model provides a technical solution: the upper end of the diaphragm placement table 3 is fixedly connected with a sliding box 12, and the interior of the sliding box 12 is slidably connected to the second moving block 13.

[0030] During operation, the sliding box 12 is slidably connected to the second moving block 13 . When the position of the second moving block 13 needs to be changed, the steel wire rod 14 is gripped tightly to make the second moving block 13 slide inside the sliding box 12 .

[0031] See also Figure 1-4 The utility model provides a technical solution: the lower ends of the two pressing plates 9 are fixedly connected with anti-slip sheets.

[0032] During operation, the anti-slip sheet is fixedly connected to the lower end of the pressing plate 9. When the pressing plate 9 fixes the diaphragm, the diaphragm will not slide, thereby affecting the punching position of the diaphragm.

[0033] See also Figure 1-4 The utility model provides a technical solution: the upper end of the placement box 1 is fixedly connected with an anti-collision pad 16.

[0034] During operation, the anti-collision pad 16 is fixedly connected to the upper end of the placement box 1, and can protect the user when the user is punching the membrane.

[0035] See also Figure 1-4 The utility model provides a technical solution: friction plates are installed inside the two handles 11.

[0036] During operation, the friction plate is fixedly connected to the interior of the handle 11. When the hand enters the interior of the handle 11, the handle 11 can be moved more stably.

[0037] In summary, when punching the diaphragm, the height of the pressure plate 9 is raised by placing the mobile phone diaphragm on the upper end of the diaphragm placement table 3. Since the slider slides inside the first movable groove 4, and the first movable groove 4 is connected to the second movable groove 5, the slider can slide inside the first movable groove 4 and the second movable groove 5, and can be placed at the position where the mobile phone diaphragm needs to be fixed. At this time, through the reaction force of the spring 8, the pressure plate 9 is driven to descend by the spring 8, the collected diaphragm is simply fixed, and the position of the slider is limited. At this time, the mechanical puncher 15 can be driven to move simultaneously by the steel wire soft rod 14. Since the steel wire soft rod 14 is corrugated and the length can be adjusted, the mobile phone diaphragm can be punched by the mechanical puncher 15. The first movable block 6 can slide inside the first movable groove 4 and multiple second movable grooves 5, so that mobile phone diaphragms of different sizes can be fixed.
