[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] refer to Figures 1-2 A laser cutting system includes a laser tube cutter 1 for cutting tubes, a vertical lifting unit 2, a feeding unit 3, and at least two collecting units 4. The vertical lifting unit 2 is located at the discharge end of the laser tube cutter 1. The feeding unit 3 is connected to the vertical lifting unit 2 in a swingable manner. The vertical lifting unit 2 is also provided with a first driving mechanism 7 for driving the feeding unit 3 to swing. The feeding unit 3 is provided with a detection module 8. The collecting units 4 are arranged vertically.

[0031] The feeding unit 3 supports the pipe cut by the laser pipe cutting machine 1 in a horizontal position; the detection module 8 is used to determine the length of the cut pipe.

[0032] The vertical lifting unit 2 is used to drive the unloading unit 3 to correspond to the position of the collection unit 4 at different heights;

[0033] The first driving mechanism 7 is used to drive the unloading unit 3 from a horizontal posture to an inclined posture so that the pipe slides into the corresponding collection unit 4.

[0034] In this design, the laser tube cutting machine 1 cuts the tube, and the unloading unit 3 supports the cut tube in a horizontal position. Then, the detection module 8 determines the length of the cut tube. After the length of the tube is detected, the vertical lifting unit 2 drives the unloading unit 3 to move to the position of the corresponding collection unit 4. Then, the first drive mechanism 7 drives the unloading unit 3 from a horizontal position to an inclined position, so that the tube slides into the corresponding collection unit 4. After the tube slides into the corresponding collection unit 4, the first drive mechanism 7 resets and turns the unloading unit 3 from an inclined position to a horizontal position. The vertical lifting unit 2 drives the unloading unit 3 to reset to support the next cut tube. In this way, the cut tubes are classified, making it easier for workers to use the tubes later.

[0035] In this embodiment, the detection module 8 includes a mounting base 81 and an infrared sensor 82 disposed on the unloading plate 31. The mounting base 81 is provided with a horizontally arranged mounting groove 811, and the infrared sensor 82 is mounted on the mounting groove 811 by bolts.

[0036] It also includes a fixing frame 5, and there are two collection units 4. Each collection unit 4 is a collection box 41, which is arranged vertically on the fixing frame 5.

[0037] Specifically, the infrared sensor 82 is detachably installed in the mounting slot 811 of the mounting base 81 by bolts, so that the position of the infrared sensor 82 can be adjusted.

[0038] There are two collection boxes 41. The top collection box 41 is the first layer for collecting pipes of the first length, and the second layer is for collecting pipes of the second length. The first and second lengths of the pipes are determined by infrared sensor 82. If the infrared rays emitted by infrared sensor 82 cannot be blocked, it is determined to be the first length, and if it can be blocked, it is determined to be the second length.

[0039] After the infrared sensor 82 determines that the cut pipe is of the first length, it sends a signal to the vertical lifting unit 2. The vertical lifting unit 2 drives the unloading unit 3 to descend, aligning the unloading unit 3 with the collection box 41 of the first layer. Then, the first driving mechanism 7 drives the unloading unit 3 to swing, causing the pipe to slide into the collection box 41. After the pipe slides down, the first driving mechanism 7 drives the unloading unit 3 to return to a horizontal position. The vertical lifting unit 2 drives the unloading unit 3 to reset to support the next pipe to be cut. When the second length is determined, the working process is similar to the above, but the vertical lifting unit 2 drives the unloading unit 3 to descend to the position between the two collection boxes 41, and then the first driving mechanism 7 drives the unloading unit 3 to swing, causing the pipe to slide into the collection box 41. In this way, the pipes of the first and second lengths are classified.

[0040] When there are three collection boxes 41, two infrared sensors 82 are installed on the mounting slot 811. The two infrared sensors 82 are arranged along the length of the feed plate 31. The lengths of the three collection boxes 41 from top to bottom are the first length, the second length and the third length. The first length cannot block the infrared rays emitted by the first infrared sensor 82. The second length can block the infrared rays emitted by the first infrared sensor 82 but cannot block the infrared rays emitted by the second infrared sensor 82. The third length can block the infrared rays emitted by both the first infrared sensor 82 and the second infrared sensor 82.

[0041] The process of classifying pipes of three lengths is similar to that of classifying pipes of two lengths. Pipes of the first length are moved to the first-layer collection box 41 by the vertical lifting unit 2 driving the unloading unit 3. Pipes of the second length are moved between the first and second-layer collection boxes 41 by the vertical lifting unit 2 driving the unloading unit 3. Pipes of the third length are moved between the second and third-layer collection boxes 41 by the vertical lifting unit 2 driving the unloading unit 3.

[0042] In this embodiment, the vertical lifting unit 2 includes a base 21, a vertically arranged guide rod 22 and threaded rod 23, and a connecting plate 24;

[0043] One end of the guide rod 22 is connected to the base 21, and the other end passes through the connecting plate 24 and is movably connected to the connecting plate 24; the base 21 is provided with a second driving mechanism 25 for driving the threaded rod 23 to rotate, one end of the threaded rod 23 is connected to the second driving mechanism 25, and the other end passes through the connecting plate 24 and is threadedly connected to the connecting plate 24.

[0044] The connecting plate 24 is provided with two spaced-apart fixing rods 241, one end of the unloading unit 3 is hinged to the two fixing rods 241, and the first driving mechanism 7 is provided on the connecting plate 24.

[0045] The feeding unit 3 is a feeding plate 31, one end of which is hinged to two fixed rods 241;

[0046] The first driving mechanism 7 includes a hydraulic cylinder 71 mounted on a connecting plate 24, the output end of which is connected to the bottom of the unloading plate 31.

[0047] In practical use, the second drive mechanism 25 can use a combination of a motor and a bevel gear to drive the threaded rod 23 to rotate, thereby realizing the lifting and lowering of the connecting plate 24.

[0048] Specifically, during the pipe cutting process, the feeding plate 31 supports the pipe in a horizontal position. After cutting, the length of the pipe is determined by the detection module 8. After detection, the second drive mechanism drives the threaded rod 23 to rotate, causing the connecting plate 24 to move up or down. When moving down, the feeding plate 31 aligns with the collection unit 4 at different heights. After the feeding plate 31 aligns with the collection box 41, the hydraulic cylinder 71 drives the feeding plate 31 to swing to an inclined position, allowing the pipe on the feeding plate 31 to slide into the collection box 41. After the feeding plate 31 slides into the collection box 41, the hydraulic cylinder 71 drives the feeding plate 31 to return to a horizontal position. Then, the second drive mechanism 25 drives the connecting plate 24 to move up and support the cut pipe again.

[0049] Preferably, the collection unit 4 further includes a support frame 6, on which two conveyor belts 61 are provided, and the conveyor belts 61 correspond one-to-one with the collection box 41;

[0050] The vertical lifting mechanism is used to drive the unloading unit 3 downward to correspond to the position of the conveyor belt 61 at different heights;

[0051] The first driving mechanism 7 is used to drive the unloading unit 3 from a horizontal posture to an inclined posture so that the pipe slides onto the corresponding conveyor belt 61.

[0052] Furthermore, the conveyor belt 61 is matched one-to-one with the collection box 41. The conveyor belt 61 transports the pipe to the corresponding collection box 41. The falling pipe has a certain inertia, and the conveyor belt 61 acts as a buffer to reduce damage to the pipe.

[0053] More preferably, limiting plates 611 are provided on both sides of the conveyor belt 61. The limiting plates 611 are used to prevent the pipe from slipping off the conveyor belt 61.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
