Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-5 As shown, this utility model is a waterproof membrane switch punching device, including an operating table 10. The operating table 10 is fixedly installed at each of the four corners of its bottom end. The operating table 10 is placed on the ground by support legs 11. A device body 12 is fixedly installed at the middle position of the top of the operating table 10. A rectangular groove is opened at the front end of the device body 12. A flip plate 13 is movably engaged in the rectangular groove of the device body 12. A punch 15 for punching is movably inserted through the middle position of the rectangular groove of the device body 12. A membrane switch processing part 14 is placed on one side of the flip plate 13. Multiple sets of locking blocks 22 are arranged between the membrane switch processing part 14 and the flip plate 13. By setting up the operating table 10 and support legs 11, a stable ground support is provided for the device, avoiding overall displacement caused by vibration during processing, and ensuring punching accuracy from the basic level. The flip plate 13 serves as a load-bearing base, and together with multiple sets of clamping blocks 22, it can quickly clamp the limit membrane switch processing part 14, making it convenient for operators to place and remove the membrane switch processing part 14. Moreover, the placement and removal process is safer than traditional vertical punching, protecting the personal safety of operators.

[0022] It should be noted that an air compressor, an air tank, and a solenoid valve are installed on one side of the control panel 10. The air compressor generates compressed air, and the air tank is used to balance the air load of the compressed air circuit, stabilize the gas pressure of the circuit, and ensure the normal operation of the second cylinder 20, the first cylinder 19, and the third cylinder 29.

[0023] like Figure 1-3As shown, a second cylinder 20 is fixedly installed at the rear end of the device body 12, and the piston rod of the second cylinder 20 is fixedly connected to the punch 15. Limiting holes 23 are opened on both sides of the flip plate 13, and first cylinders 19 are fixedly installed on both the left and right sides of the device body 12. The piston rods of the first cylinders 19 movably penetrate the side wall of the rectangular groove of the device body 12 and can be movably engaged in the corresponding limiting holes 23. The locking block 22 is L-shaped, and multiple sets of locking blocks 22 are fixedly installed on the side wall of the flip plate 13. The membrane switch processing part 14 is engaged in the multiple sets of locking blocks 22. A sponge pad 16 is fixedly installed in the rectangular groove of the device body 12, and the sponge pad 16 has a locking cavity at the position of the multiple sets of locking blocks 22. By setting the second cylinder 20 to provide a stable and adjustable driving force for the punch 15, the depth and speed of each punching can be kept consistent. By setting the first cylinder 19 and the limiting hole 23 to cooperate, the manual fixing of the flip plate 13 is replaced. After locking, the flip plate 13 is prevented from shaking during punching, which would cause the workpiece to be scrapped. By setting the sponge pad 16, the membrane switch workpiece 14 can be prevented from making hard contact with the equipment body 12, which can effectively reduce edge crushing, surface scratches and other problems, and reduce processing losses.

[0024] like Figure 4-5 As shown, a flipping assembly is provided between the flip plate 13 and the equipment body 12. The flipping assembly includes a rotating shaft 24 and a pushing unit 21. One end of the rotating shaft 24 movably passes through the equipment body 12 and is fixedly connected to a gear 25. The pushing unit 21 includes a third cylinder 29 and a rack 26, with the rack 26 movably meshing with the gear 25. The rotating shaft 24 is fixedly connected to one end of the flip plate 13 near the equipment body 12. The flip plate 13 is movably connected to the equipment body 12 via the rotating shaft 24. One end of the rotating shaft 24 is movably mounted on one side of the rectangular groove of the equipment body 12 via a bearing, and the other end of the rotating shaft 24 movably passes through the rectangular groove of the equipment body 12. The third cylinder 29 is mounted on the side wall of the equipment body 12 via an assembly block. The piston rod of the third cylinder 29 is fixedly connected to the rack 26, which is located below the third cylinder 29. A guide rod 28 is fixedly installed between the assembly block of the third cylinder 29 and the operating table 10. Two sets of guide blocks 27 are fixedly installed on one side of the rack 26, and the guide rod 28 moves through the two sets of guide blocks 27. By setting the third cylinder 29 to drive the rack 26 to move, the rack 26 and gear 25 are activated to mesh, and the gear 25 drives the rotating shaft 24 to rotate, the linear motion is converted into rotational motion. By setting the cooperation between the guide rod 28 and the guide block 27, the movement trajectory of the rack 26 is strictly limited, avoiding the rack 26 from deviating and causing misalignment of the gear 25, reducing the wear of the transmission components, and extending the service life of the tilting assembly.

[0025] like Figure 1 and Figure 2As shown, a device switch 17 and a control box 18 are fixedly installed on the top of the operating table 10. The device switch 17 and the control box 18 are electrically connected, and the control box 18 is electrically connected to the second cylinder 20, the first cylinder 19, and the third cylinder 29. A PLC is installed in the control box 18. The working status of the second cylinder 20, the first cylinder 19, and the third cylinder 29 is electrically controlled by the program set by the PLC, thereby realizing the fully automated coordination of locking after the flip plate 13 flips, punching hole 15, unlocking the flip plate 13, and flipping the flip plate 13 to unload materials, improving processing efficiency and product consistency.

[0026] The implementation principle of this utility model's waterproof membrane switch punching device is as follows: First, the operator triggers the control box 18 via device switch 17. The PLC inside the control box 18 starts the air compressor, air tank, and solenoid valve, allowing compressed air to enter the air circuit system. The air tank balances the air load and stabilizes the gas pressure, while the solenoid valve controls the airflow direction, providing stable power to the first cylinder 19, the second cylinder 20, and the third cylinder 29. Subsequently, the PLC controls the piston rod of the third cylinder 29 to extend, pushing the rack 26 to move linearly along the guide rod 28. The rack 26 meshes with the gear 25, driving the rotating shaft 24 to rotate, which in turn causes the flip plate 13 to flip around the rotating shaft 24 to an angle suitable for loading. The operator places the membrane switch processing part 14 into the L-shaped clamping block 22 of the flip plate 13. The clamping block 22 clamps and limits the processing part, while the bottom of the processing part contacts the sponge pad 16 in the rectangular groove of the equipment body 12 to avoid hard friction damage.

[0027] Secondly, after loading, the PLC controls the piston rod of the third cylinder 29 to retract, and the rack 26 to move in the opposite direction. Through the gear 25 and the rotating shaft 24, the flip plate 13 is driven to return to the processing position within the rectangular groove of the equipment body 12. Subsequently, the PLC drives the first cylinder 19 to operate, its piston rod penetrating through the side wall of the equipment body 12 and engaging the limiting hole 23 of the flip plate 13, achieving rigid locking of the flip plate 13 and preventing it from shaking during punching. After locking, the PLC controls the piston rod of the second cylinder 20 to extend downward, pushing the punch 15 vertically downward along the through channel in the middle of the rectangular groove of the equipment body 12 to precisely punch the membrane switch processing part 14. Because the second cylinder 20 provides a stable and controllable driving force, the depth and speed of each punching can be kept consistent, ensuring processing accuracy.

[0028] Finally, after punching, the PLC first controls the piston rod of the second cylinder 20 to retract upwards, driving the punch 15 back to its initial position to avoid interference with subsequent actions of the workpiece; then it controls the piston rod of the first cylinder 19 to retract, releasing the lock on the flip plate 13. Subsequently, the PLC drives the third cylinder 29 again, which, through the rack 26 and gear 25, drives the rotating shaft 24 to flip the flip plate 13 outwards, allowing the operator to remove the punched membrane switch workpiece 14 from the clamping block 22. This completes a single processing cycle, and the steps are repeated for batch processing.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
