[0029] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0030] This invention discloses a laser drilling machine for airbag burst tubes. (Refer to...)

A reset structure is provided between the first abutment 6 and the rotating block 43. A clamping structure is provided on the fixed cover 5. A fixed cylinder 8 is fixedly connected to the top of one side of the other second fixed plate 3. A hydraulic cylinder 7 is installed on the top of the corresponding other side of the second fixed plate 3. One end of the output shaft of the hydraulic cylinder 7 is connected to a moving cylinder 9. The movable cylinder 9 is movably sleeved on the fixed cylinder 8. A second abutment 12 is provided at one end of the movable cylinder 9, and a fixing ring 11 is provided at the other end of the movable cylinder 9. A rod 10 is fixedly inserted into the fixing ring 11. A first transverse groove 13 is opened on the side of the fixed cylinder 8. A first driving groove 14 is opened on the side of the fixed cylinder 8, which connects to one end of the first transverse groove 13. A second transverse groove 15 is opened on the side of the fixed cylinder 8, which connects to the first driving groove 14. A second driving groove 16 is opened on the side of the fixed cylinder 8, which connects to one end of the second transverse groove 15. One end of the rod 10 is movably inserted into the first transverse groove 13.

[0032] The clamping structure includes multiple clamping ports 17 opened on the side of the fixed cover 5. A rotating shaft is rotatably connected between the inner walls on both sides of each clamping port 17. A flip handle 18 is fixedly sleeved on both ends of the rotating shaft. A clamping block 19 is installed on one end of the flip handle 18. A driving structure is provided between the rotating shaft and the first abutment plate 6.

[0033] The driving structure includes a driving bar 20 connected to the first abutment plate 6. Each driving bar 20 moves through the corresponding clamping port 17. A gear 21 is fixedly sleeved in the middle of the rotating shaft. The driving bar 20 is provided with teeth that mesh with the gear 21.

[0034] The reset structure includes multiple through rods 22 connected to the first abutment plate 6. Each through rod 22 moves through the fixed cover 5. A movable plate 23 is provided at one end of the through rod 22. The movable plate 23 is movably sleeved on the fixed rod 4. A spring 24 is sleeved on the fixed rod 4. The two ends of the spring 24 are respectively connected to the movable plate 23 and the rotating block 43.

[0035] The movable lifting structure includes a screw 28 that rotates through two third fixed plates 25. A first motor 27 is mounted on one of the third fixed plates 25, and one end of the output shaft of the first motor 27 is connected to the screw 28. A limiting rod 29 is fixedly connected between the two third fixed plates 25. A movable seat 30 is movably sleeved on the limiting rod 29. The movable seat 30 has a threaded groove for the screw 28 to pass through. An electric telescopic rod 31 is mounted below the movable seat 30. A laser drilling head 26 is installed at the bottom end of the output shaft of the electric telescopic rod 31. When drilling, the hydraulic system on the second fixed plate 3 is activated. The cylinder 7 drives the movable cylinder 9 to move within the fixed cylinder 8. The rod 10 on the fixed ring 11 slides in the first transverse groove 13. As the movable cylinder 9 moves, it pushes the other end of the rupture tube, causing the first abutment 6 to move within the fixed cover 5. When the first abutment 6 moves, it drives the rotating handle 18 to rotate via the drive bar 20 and gear 21. When the first abutment 6 moves to the inner end face of the fixed cover 5, the clamping block 19 at one end of the rotating handle 18 clamps onto the rupture tube. At the same time, the first abutment 6 drives the movable disc 23 at one end of the through rod 22 to move, compressing the compression spring 24. In this way, the blasting tube is fixed between the first abutment plate 6 and the second abutment plate 12. Then, the first motor 27 is started. The first motor 27 is a bidirectional motor. The first motor 27 drives the screw 28 to rotate, and the moving seat 30 drives the laser drilling head 26 to move to the corresponding position. The electric telescopic rod 31 is started to drive the laser drilling head 26 to move down and drill a hole in the blasting tube. After drilling, the laser drilling head 26 moves up to reset. Then, the moving cylinder 9 continues to move. The moving cylinder 9 drives the insertion rod 10 to slide in the first driving groove 14, thereby driving the blasting. The tube automatically flips over. When one end of the insertion rod 10 slides into the second transverse groove 15, the blasting tube stops flipping. At this time, the position of the laser drilling head 26 is adjusted and the drilling work on the blasting tube continues. Then, the moving cylinder 9 is moved to drive one end of the insertion rod 10 to slide in the second driving groove 16, thereby continuing to flip the blasting tube. The laser drilling head 26 is used to continue to drill holes in the flipped blasting tube. In this way, the blasting tube is automatically clamped and flipped while being automatically clamped, which meets the drilling work at different positions on the blasting tube, making the operation more labor-saving and convenient.

[0036] See Figure 1 , Figure 3 and Figure 6 The material transfer structure includes a rotating rod 32 that rotates through two first fixed plates 2. A second motor 33 is installed on one of the first fixed plates 2. One end of the output shaft of the second motor 33 is connected to the rotating rod 32. Two fixed plates 34 are fixedly sleeved on the rotating rod 32. A switching cylinder 35 is fixedly installed on the two fixed plates 34. Multiple storage slots 36 are opened at equal angles on the side circumference of the switching cylinder 35. A shielding structure is set between the two second fixed plates 3.

[0037] The barrier structure includes two sets of connecting rods 38 connected to two second fixed plates 3, and a baffle plate 37 is installed between the two connecting rods 38 in each set;

[0038] The material storage structure includes a first support 39 positioned at the front edge of the base plate 1, with a receiving frame 40 mounted on top of the first support 39. The inner wall of the receiving frame 40 is inclined away from the first fixed plate 2. A second support 41 is positioned at the rear edge of the base plate 1, with a storage frame 42 mounted on top of the second support 41. The inner wall of the storage frame 42 is inclined towards the first fixed plate 2. A bursting tube to be drilled is stored in the storage frame 42. When the second motor 33 on the first fixed plate 2 is activated, it drives the rotating rod 32, the fixed plate 34, and the switching cylinder 35 to rotate as a whole. The arc-shaped side of the switching cylinder 35 shields the bursting tube inside the storage frame 42, preventing it from rolling out. When switching... When the storage slot 36 on the switching cylinder 35 rotates to the discharge port of the storage frame 42, the blasting tubes in the storage frame 42 automatically roll into the storage slot 36. As the switching cylinder 35 continues to rotate, it drives the blasting tubes to the opening position for drilling. During the rotation of the switching cylinder 35, the baffle plate 37 blocks the blasting tubes stored in the storage slot 36 to prevent them from falling out of the storage slot 36. After drilling the blasting tubes, as the switching cylinder 35 continues to rotate, it not only promptly feeds the next blasting tube to the opening position for processing, but also drives the drilled blasting tubes to the receiving frame 40 for discharge. This makes reasonable use of working time and greatly improves the drilling efficiency.

[0039] The implementation principle of a laser drilling machine for airbag burst tubes according to an embodiment of the present invention is as follows: First, the burst tube to be drilled is placed in the storage frame 42. The second motor 33 on the first fixed plate 2 is started to drive the rotating rod 32, the fixed plate 34, and the switching cylinder 35 to rotate as a whole. The arc-shaped side of the switching cylinder 35 blocks the burst tube in the storage frame 42 to prevent the burst tube stored in the storage frame 42 from rolling off. When the storage groove 36 on the switching cylinder 35 rotates to the discharge port of the storage frame 42, the burst tube in the storage frame 42 automatically rolls off into the storage groove 36. As the switching cylinder 35 continues to rotate, it drives the fed burst tube to the drilling position. Then, the hydraulic cylinder 7 on the second fixed plate 3 is activated, driving the moving cylinder 9 to move within the fixed cylinder 8. The insert rod 10 on the fixed ring 11 slides in the first transverse groove 13. As the moving cylinder 9 moves, it pushes the other end of the rupture tube, causing the first abutment 6 to move within the fixed cover 5. When the first abutment 6 moves, it drives the rotating handle 18 to rotate via the drive bar 20 and gear 21. When the first abutment 6 moves to the inner end face of the fixed cover 5, the clamping block 19 at one end of the rotating handle 18 clamps onto the rupture tube. At the same time, the first abutment 6 drives the moving disc 23 at one end of the through rod 22 to move, compressing the compression spring 24. Thus, the rupture tube is fixed to the first abutment 6. Between the second abutment plate 12, the first motor 27 is then started. The first motor 27 is a bidirectional motor. The first motor 27 drives the screw 28 to rotate, and the moving seat 30 drives the laser drilling head 26 to move to the corresponding position. The electric telescopic rod 31 is then started to drive the laser drilling head 26 to move down and perform drilling on the blasting tube. After drilling, the laser drilling head 26 moves up to reset. Then, the moving cylinder 9 continues to move. The moving cylinder 9 drives the insertion rod 10 to slide in the first driving groove 14, thereby causing the blasting tube to automatically flip. When one end of the insertion rod 10 slides into the second transverse groove 15, the blasting tube stops flipping. At this time, the laser drilling head 26 is adjusted further. The tube is moved to position 6 and the drilling work continues on the rupture tube. Then, the moving cylinder 9 is moved, which drives one end of the insertion rod 10 to slide in the second driving groove 16, thereby continuing to flip the rupture tube. The laser drilling head 26 is used to continue to drill holes in the flipped rupture tube. In this way, the rupture tube is automatically clamped and flipped at the same time to meet the drilling requirements at different positions on the rupture tube. After drilling, the switching cylinder 35 continues to rotate, which not only loads the next rupture tube to the drilling position in time to continue drilling, but also drives the drilled rupture tube to the receiving frame 40 for unloading. This makes reasonable use of the working time and greatly improves the drilling efficiency.

[0040] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
