[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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.

[0024] like Figure 1-8 As shown, the embodiment of the present invention includes:

[0025] A laser tube cutting device includes an x-axis forward conveyor 1, a diverter air claw 2, a first yz-axis linear module 3, a pipe tooling 4, a laser cutter 5, a second yz-axis linear module 6, and an upper spiral rising flow channel 7. The end of the x-axis forward conveyor 1 is matched with a diverter air claw 2, and the diverter air claw 2 is mounted on the first yz-axis linear module 3. A group of pipe tooling 4 is docked at each end of the first yz-axis linear module 3. The pipe tooling 4 is matched with a laser cutter 5 on the opposite side of the diverter air claw 2. The laser cutter 5 is mounted on a second yz-axis linear module 6 that spans each pipe tooling 4. The second yz-axis linear module 6 is suspended above the x-axis forward conveyor 1 and forms an upper spiral rising flow channel 7.

[0026] Among them, two x-axis diversion linear modules 8 with equal height docking pipe fixtures 4 are arranged on both end sides of the first yz-axis linear module 3. The x-axis diversion linear module 8 expands the upper spiral flow channel 7 into a vortex flow channel 9. The vortex flow channel 9 has a double-layer structure starting from the diversion air claw 2 and ending at the laser cutter 5.

[0027] Furthermore, a waste removal air nozzle 10 is coaxially integrated at the front end of the laser cutter 5, and a waste receiving slide 11 is arranged on the opposite side of the waste removal air nozzle 10 with respect to the pipe tooling 4, and an x-axis reverse conveyor 12 is connected to the waste receiving slide 11.

[0028] Furthermore, the laser cutter 5 is mounted on the second yz-axis linear module 6 through a back plate 13. A lifting cylinder 14 is also provided on the back plate 13. A dust collecting nozzle 15 is mounted on the lower end of the lifting cylinder 14. The dust collecting nozzle 15 is matched directly above the pipe tooling 4.

[0029] Furthermore, the pipe fixture 4 is configured as a chuck 16 that coaxially matches the diverter air gripper 2 , and the chuck 16 is carried on a rotating motor 17 , and a basic base is further provided at the bottom of the rotating motor 17 .

[0030] Furthermore, a number of processing stations are equidistantly matched along the travel of the x-axis diversion linear module 8. The processing stations are provided with a pipe tooling 4 and a burr trimming mechanism 18 and a good product testing mechanism 19 arranged in sequence. The x-axis diversion linear module 8 is mounted with synchronous transporting air grippers 20 equal to the number of processing stations, and adjacent synchronous transporting air grippers 20 are connected in series with each other.

[0031] Furthermore, the burr trimming mechanism 18 includes a burr milling cutter 21 and a first servo lifting module 22 for pulling the burr milling cutter 21 . The burr milling cutter 21 is covered by a protective tube 23 that is coaxially matched with the pipe tooling 4 .

[0032] Furthermore, the good product testing mechanism 19 includes a contact displacement sensor 24 and a second servo lifting module 25 that pulls the contact displacement sensor 24. There are four contact displacement sensors 24 that are arranged in a cross form and coaxially matched directly above the pipe fixture 4.

[0033] Furthermore, an NG sorting robot is connected to the downstream of the x-axis diversion linear module 8, and an NG box and a qualified product conveyor are provided within the operating range of the NG sorting robot. The NG sorting robot is electrically connected to a controller, and the contact displacement sensor 24 is electrically connected to the controller.

[0034] Cutting metal pipes to length is typically accomplished using laser cutting technology. However, in automated production, laser cutting is relatively slow, leading to congestion in upstream material delivery. Existing technology typically increases throughput by installing multiple diversion lines. While this improves production efficiency, it also requires exponentially increasing the scale of the equipment. Due to the limited floor space allocated to individual production units, this increased equipment size hinders factory production.

[0035] This equipment integrates the processes of pipe feeding, laser pipe cutting, scrap recycling, milling cutter deburring, quality testing, and NG sorting in an orderly manner. It also rationally constructs a double-layer structure of the gyratory flow channel 9 according to the beat requirements of the laser pipe cutting process, and utilizes the upstream redundant space to reversely compress the scale of the assembly line, thereby alleviating the congestion problem of upstream incoming materials and improving the throughput efficiency of downstream processing stations without changing the scale of the entire machine.

[0036] Specifically, the original pipe first flows along the x-axis forward conveyor 1 to the diverter claw 2, and then the diverter claw 2 grabs the pipe (see Figure 7 、 Figure 8 Steps S1 and S2), and horizontal transport (see Figure 7 、 Figure 8 Step S3) to Figure 2 The pipe fitting 4 shown in the figure is located on the upper side (see Figure 7 、 Figure 8 In step S4, the pipe fixture 4 uses an air gripper to hold the pipe upright. The second YZ-axis linear module 6 then loads the laser cutter 5 into the designated position for laser cutting. Before cutting begins, a dust collection nozzle is pressed against the front end of the laser cutter 5, covering the entire pipe to be processed. The rotary motor 17 then synchronizes the rotation of the pipe during the laser cutting process, causing the laser focus to orbit the pipe once before severing the pipe. Any scrap material is blown away by a blowpipe at the laser head, falling onto a slide and being transferred to the X-axis reverse conveyor 12.

[0037] The second inventive aspect of this device is that, unlike conventional assembly lines, which run in a straight line to the end, waste is blown into a waste box for manual recycling. This device, however, differs from existing technologies by implementing an automatic waste collection function without human intervention. Specifically, the X-axis reverse conveyor 12 operates in reverse, creating a downward rotating flow channel that is essentially equivalent to the main line of the device. This fully utilizes redundant upstream space, avoids encroaching on downstream processing equipment, and further compacts the overall structure.

[0038] The third invention of this device is that as the waste is refluxed, the semi-finished pipe is further transported to the downstream processing station by the x-axis diversion linear module 8 (see Figure 7 、 Figure 8In step S5), the downstream processing stations use a synchronous alternating transport method to further improve the compactness between the stations and ensure the compactness of the equipment scale.

[0039] Since the whole machine adopts multiple space compression methods, it achieves better space utilization.

[0040] In summary, the present invention provides a laser tube cutting device. To address the problem of doubling the floor space due to the expansion of the equipment scale, a double-layer structure of an upper spiral flow channel 7 or a spiral flow channel 9 is established to enable larger-scale workstations to be stacked three-dimensionally. The three-dimensional stacking method can make full use of upstream redundancy, thereby doubling production efficiency without expanding the equipment scale.

[0041] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
