[0042] Specifically, a control box 22 is fixedly installed below the top of the Z-shaped plate frame 4, and the control line of the weld scanning camera 18 passes through the hard wire tube 19 and is electrically connected to the controller inside the control box 22 through the optical fiber cable drag chain 20 for communication, and the synchronous belt electric guide rail 15, the laser cleaning machine cabinet 21, the power mechanism, the cylinder 11, the electric rotating table 12, the cylinder 2 13 and the electric rotating table 2 14 are electrically connected to the controller inside the control box 22 for communication; the controller adopts existing technology, such as the PLC controller in the existing technology, so it will not be described in detail here.

[0043] Specifically, the power mechanism includes a gear box 6 and a motor 7, and the gear box 6 is fixedly mounted on the base 1, and the motor 7 is fixedly mounted on the outside of the gear box 6; the output end of the motor 7 rotates and extends into the interior of the gear box 6 and is fixedly connected to the input gear 61 inside the gear box 6, and an axial hole 28 is opened through the gear box 6, so that the stability between the gear box 6 and the rotating shaft 8 and the smoothness during the rotation process can be ensured through the axial hole 28, and the partial rotation of the output gear 62 inside the gear box 6 is in the axial hole 28; the part of the rotating shaft 8 with the gear 81 is rotatably mounted in the axial hole 28 on the gear box 6, and the gear 81 is meshed and connected with the output gear 62 inside the gear box 6; the input gear 61 is meshed and connected with the output gear 62; so that the motor 7 transmits power to the gear 81 through the input gear 61 and the output gear 62 inside the gear box 6, thereby rotating the rotating shaft 8.

[0044] Specifically, an axial hole 28 is respectively formed at the top of support platform 1 2 and support platform 2 3, and a bearing 29 is fixedly installed in the axial hole 28; the rotating shaft 8 is rotatably installed in the axial hole 28 at the top of support platform 1 2 and support platform 2 3 through the bearing 29, and both ends of the rotating shaft 8 are evenly extended from the axial hole 28 at the top of support platform 1 2 and support platform 2 3; so that the stability between the rotating shaft 8 and support platform 1 2 and support platform 2 3 and the smoothness during rotation are ensured through the axial hole 28 and the bearing 29.

[0045] Specifically, threaded holes 82 are respectively provided at both ends of the rotating shaft 8, and a number of slots 83 are evenly distributed on the circumferential surfaces of both ends of the rotating shaft 8; bolts 24 are fixedly installed in the corresponding threaded holes 82 to facilitate the disassembly and assembly of material tray 1 9 and material tray 2 10; material tray 1 9 and material tray 2 10 are snap-fitted with the corresponding slots 83.

[0046] Specifically, a countersunk hole 23 is formed through the center of the surface of the material tray 1 9 and the material tray 2 10 to hide the bolt 24, and a shaft sleeve 25 is fixedly installed on the inner side of the surface of the material tray 1 9 and the material tray 2 10 to ensure the stability between the material tray 1 9 and the material tray 2 10 and the rotating shaft 8, and a plurality of protrusions 26 corresponding to the slots 83 are fixedly installed on the inner surface of the shaft sleeve 25; the countersunk hole 23 is connected to the corresponding shaft sleeve 25; the bolt 24 is fixedly installed in the corresponding countersunk hole 23; the material tray 1 9 and the material tray 2 10 are sleeved on both ends of the rotating shaft 8 through the shaft sleeve 25; the protrusion 26 is stuck in the corresponding slot 83 to prevent the material tray 1 9 and the material tray 2 10 from rotating.

[0047] In this embodiment, when the weld 31 of the welded steel pipe 30 is laser cleaned, it can be used in conjunction with an external automatic loading device and unloading equipment, such as a robotic arm; when in use, the external loading robotic arm device is placed on the front side of the material rack, and the unloading robotic arm device is placed on the rear side of the material rack, and the welding steel pipe 30 is placed in the corresponding material trough 27 on the front side of the material tray 1 9 and the material tray 2 10 in order by the loading robotic arm device, and the welding steel pipe 30 between the material tray 1 9 and the material tray 2 10 that has been laser cleaned can be removed by the unloading robotic arm device;

[0048] At the same time, manual loading is also possible. When loading, the welded steel pipe 30 is placed in the corresponding material trough 27 on the front side of the material tray 1 9 and the material tray 2 10, and the weld 31 on the welded steel pipe 30 is between the material tray 1 9 and the material tray 2 10;

[0049] After placement, the material rack is driven to rotate by the power mechanism, so that the welded steel pipes 30 on the material tray 1 9 and the material tray 2 10 are moved to the top of the laser cleaning head 17 and stop rotating;

[0050] Then, the cylinder 1 11 and the cylinder 2 13 drive the electric rotating table 1 12 and the electric rotating table 2 14 to clamp the welded steel pipe 30;

[0051] At this time, the slide 16 is driven by the synchronous belt electric guide rail 15 to simultaneously drive the laser cleaning head 17 and the weld scanning camera 18 to move, so that the weld scanning camera 18 scans and locates the weld 31 on the welded steel pipe 30. When the weld scanning camera 18 scans the weld 31 on the welded steel pipe 30, the controller receives the signal transmitted by the weld scanning camera 18 and stops the synchronous belt electric guide rail 15 from moving. At this time, the position of the laser cleaning head 17 just corresponds to the weld on the welded steel pipe 30.

[0052] Finally, the electric rotating table 12 and the electric rotating table 2 14 drive the welded steel pipe 30 to rotate 360 ​​degrees. During the rotation, the laser cleaning head 17 can be used to laser clean the weld on the welded steel pipe 30.

[0053] During the cleaning process, the welded steel pipe 30 can be placed in the corresponding material trough 27 at the front side of the material tray 1 9 and the material tray 2 10 in advance;

[0054] In this way, after the weld 31 on the previous welded steel pipe 30 is laser cleaned, the material rack is driven to rotate by the power mechanism, so that the next welded steel pipe 30 on the material tray 1 9 and the material tray 2 10 is moved to the top of the laser cleaning head 17 and stops rotating;

[0055] The weld 31 on the welded steel pipe 30 is laser cleaned in the above manner;

[0056] During the process of cleaning the weld seam on the welded steel pipe 30, the welded steel pipe 30 whose weld seam has been cleaned before can be removed; and then the cycle can be run in the above manner.

[0057] When it is necessary to laser clean the welds on welded steel pipes 30 of different sizes, the material tray 1 9 and the material tray 2 10 matching the size of the welded steel pipe 30 can be replaced so as to laser clean the welds on welded steel pipes 30 of various sizes, thereby improving the overall applicability.
