[0025] 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.
[0026] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a microporous membrane CO2 laser rapid drilling mechanism, including an operating table 1, a mounting frame 3 is fixedly connected to the upper part of the operating table 1, an exhaust gas treatment component 19 is arranged at the lower part of the operating table 1, a motor 6 is arranged on the right side of the outside of the mounting frame 3, a screw rod 7 is fixedly connected to the output end of the motor 6, the screw rod 7 is rotatably connected to the inside of the mounting frame 3, a movable plate 8 is threadedly connected to the outside of the screw rod 7, both sides of the inside of the movable plate 8 are fixedly connected to cross bars 10, the bottoms of the two cross bars 10 are fixedly connected to cross plates 11, an electric push rod 13 is arranged on the rear side of the lower part of the cross plate 11, and a mounting block 14 is fixedly connected to the output end of the electric push rod 13, Guide rings 15 are fixedly connected to the outside of the mounting block 14 on both sides, a laser drilling head 17 is installed at the lower part of the mounting block 14, a mounting rod 18 is fixedly connected to the outside of the mounting block 14, sliding rods 9 are fixedly connected to the inside of the mounting frame 3 on both sides, the movable plate 8 is slidably connected to the outside of the two sliding rods 9, a fixing ring 5 is fixedly connected to the right side of the outside of the mounting frame 3, the motor 6 is fixedly connected to the inside of the fixing ring 5, a fixing block 12 is fixedly connected to the rear side of the lower part of the cross plate 11, an electric push rod 13 is fixedly connected to the inside of the fixed block 12, U-shaped rods 16 are fixedly connected to the outside of the cross plate 11 on both sides, and two guide rings 15 are slidably connected to the outside of the two U-shaped rods 16.
[0027] When the lateral position of the laser drilling head 17 needs to be adjusted, the motor 6 is started. After receiving the start signal, the motor 6 starts working quickly, driving the screw 7 fixedly connected to its output end to rotate. The rotation of the screw 7 does not exist in isolation. It converts the rotational motion into linear motion by connecting with the external thread of the moving plate 8. Driven by the screw 7, the moving plate 8 moves laterally outside the two slide bars 9. This design not only ensures the stability of the movement, but also greatly improves the accuracy of the adjustment. The movement of the moving plate 8 is not the end point. It also drives the cross bars 10 fixed on both sides of the interior to move. The movement of the cross bar 10 further drives the movement of the cross plate 11 fixed at the bottom. Its movement directly determines the lateral position of the laser drilling head 17. When the cross plate 11 moves to the predetermined position, the lateral position adjustment of the laser drilling head 17 is completed. At this time, the motor 6 is turned off and the electric push rod 13 is started. After the electric push rod 13 receives the start signal, the mounting block 14 fixedly connected to its output end begins to move. The movement of the mounting block 14 is not disorderly, and it is guided and moved outside the two U-shaped rods 16 by two guide rings 15. This design ensures the stability and accuracy of the mounting block 14 during movement. As the mounting block 14 moves, the laser drilling head 17 installed at its lower part also moves. In this way, we have achieved the longitudinal position adjustment of the laser drilling head 17. It can ensure that the laser drilling head 17 can accurately align with the predetermined position of the workpiece, so as to achieve precise drilling, and realize the convenience of all-round adjustment of the position of the laser drilling head 17, which can adapt to workpieces of different shapes and sizes. Regardless of whether the surface of the workpiece is flat, curved or complex, precise drilling can be achieved by adjusting the position of the laser head.
[0028] Reference Figure 3 , Figure 4 and Figure 5 The exhaust gas treatment component 19 includes a fan 1901, which is fixedly connected to the upper part of the operating table 1, and the output end of the fan 1901 is fixedly connected to the air outlet 1902, and the input end of the fan 1901 is fixedly connected to the treatment box 1903, a filter plate 1904 is installed on the left side of the treatment box 1903, an activated carbon adsorption plate 1905 is installed on the right side of the treatment box 1903, and the outside of the treatment box 1903 is fixedly connected to one end of the delivery pipe 1906, and the other end of the delivery pipe 1906 is fixedly connected to the air suction hood 1907, and the air suction hood 1907 is fixedly connected to the outside of the mounting rod 18, and the legs 2 are fixedly connected on both sides of the lower part of the operating table 1, and the controller 4 is installed on the right side of the outside of the mounting frame 3, and the controller 4 is electrically connected to the motor 6.
[0029] When the laser drilling head 17 is used to punch holes in the microporous membrane, a certain amount of smoke will be generated. The smoke not only contains particulate matter, but also may contain harmful substances, causing certain pollution to the environment. When the laser drilling head 17 starts working, the fan 1901 is started synchronously. The strong suction force of the fan 1901 quickly sucks the smoke generated during the laser drilling process through the suction hood 1907. The smoke is then transported to the inside of the processing box 1903 through the conveying pipe 1906. Inside the processing box 1903, the smoke first passes through the filter plate 1904. The filter plate 1904 is made of advanced filter material and can effectively intercept the particulate matter in the smoke, preventing it from continuing to flow forward. After being processed by the filter plate 1904, most of the particulate matter in the smoke is successfully filtered out, significantly reducing the pollution level of the smoke. Then, the smoke that has been initially filtered continues to flow forward and comes to the activated carbon adsorption plate 1905. The activated carbon adsorption plate 1905 uses its strong adsorption capacity to deeply filter the harmful substances in the smoke. The porous structure of activated carbon can adsorb and fix harmful substances, further reducing the pollutant content in the smoke. Finally, the smoke has become relatively clean after two filtering processes. The filtered gas is discharged through the air outlet 1902 and returned to the surrounding environment, which makes it easier to filter and purify the smoke generated during the laser drilling of the microporous membrane, thereby reducing pollution to the environment and improving the quality of the surrounding environment.
[0030] Working principle: when it is necessary to adjust the position of the laser drilling head 17, start the motor 6, the motor 6 rotates with the screw rod 7 fixedly connected to the output end, the screw rod 7 rotates and drives the movable plate 8 connected with the external thread to move laterally outside the two sliding rods 9, the movable plate 8 moves with the cross bars 10 fixed on both sides of the inside, the two cross bars 10 move with the cross plate 11 fixed at the bottom, the cross plate 11 moves and drives the laser drilling head 17 installed at the bottom to move laterally, when the horizontal position adjustment of the laser drilling head 17 is completed, turn off the motor 6, start the electric push rod 13, the electric push rod 13 drives the mounting block 14 fixedly connected to the output end to move, the mounting block 14 moves outside the two U-shaped rods 16 through two guide rings 15, and moves with the laser drilling head 17 installed at the bottom when the mounting block 14 moves, so as to adjust the longitudinal position of the laser drilling head 17, so as to realize the convenience of all-round adjustment of the laser The position of the optical drilling head 17 can adapt to workpieces of different shapes and sizes. Regardless of whether the surface of the workpiece is flat, curved or complex, precise drilling can be achieved by adjusting the position of the laser head. Then, when the laser drilling head 17 is used to drill holes in the microporous membrane, the fan 1901 is started, and the smoke generated during laser drilling is inhaled through the suction hood 1907, and then transported to the inside of the treatment box 1903 through the delivery pipe 1906. The smoke transported to the inside of the treatment box 1903 first passes through the filter plate 1904 to filter the particulate matter in the smoke, and then passes through the activated carbon adsorption plate 1905 to filter the harmful substances in the smoke. Finally, the filtered gas will be discharged through the air outlet 1902, so that when the microporous membrane is laser drilled, it is convenient to filter and purify the smoke generated during drilling, which can reduce pollution to the environment and improve the quality of the surrounding environment.
