[0019] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1: To solve the problem that smoke and dust cannot be sucked automatically following the position change of the cutting head due to the inability to intelligently and accurately control the suction position, the following technical solution is proposed: Reference Figure 1 - Figure 8 As shown, in this embodiment, a laser cutting device with a waste recycling mechanism comprises an XY-axis slide 3 arranged on a cutting machine body 1, a mobile end 4 is arranged on the XY-axis slide 3, a cutting machine head 5 is installed at the lower end of the mobile end 4, a control panel is embedded outside the cutting machine body 1, and a recycling mechanism is arranged on the outer side of the mobile end 4 corresponding to the cutting machine head 5 horizontally, and the recycling mechanism comprises an expansion box 7 connected to a pneumatic suction source; An expansion assembly for adjusting the suction area is arranged in the expansion box 7, and the expansion assembly includes a side receiving box 1 8 and a side receiving box 2 17 plugged into the expansion box 7. A main receiving box 16 connected to the side receiving box 1 8 and the side receiving box 2 17 is arranged through the inner ring side of the expansion box 7, and an absorption hole 19 is arranged through the main receiving box 16; Reference Figure 2 and Figure 6 - Figure 8 As shown, the recovery mechanism also includes a driven component 14 connected to the main receiving box 16, and the driven component 14 includes a ring-shaped toothed ring 24 plugged in at the end, and the two ends of the toothed ring 24 are respectively provided with a plug rod 25 and a plug hole 26, and the adjacent toothed rings 24 are connected by plugging the plug rod 25 and the plug hole 26. The lower part of the plurality of toothed rings 24 is provided with a support rail 15, and the upper end of the support rail 15 is provided with a rail rod 22, and each toothed ring 24 is provided with a rail groove 23 matching the rail rod 22 at the lower end, and the lower end of the support rail 15 is installed with a symmetrically arranged fixed rod 11, and the fixed rod 11 is connected to the bottom of the mobile end 4; Reference Figure 8 As shown, a mounting seat 6 is installed on one side of the mobile end 4, a motor 27 is installed at the lower end of the mounting seat 6, the output end of the motor 27 is connected to the rotating rod 12, and the lower end of the rotating rod 12 is fixedly connected to a moving gear 13 meshing with the gear ring 24; A flip cover 2 is hingedly connected to the upper end of the cutting area of ​​the cutting machine body 1. The flip cover 2 is a transparent glass structure. During the cutting process, the laser cutting process can be observed in real time through the flip cover 2 of the transparent glass structure. The control system includes a surface parameter acquisition module, a cutting path analysis module and a suction area adjustment module; A camera is arranged on the side of the cutting machine head 5, and the surface image of the workpiece during laser cutting is acquired through the camera. The surface parameter acquisition module is used to acquire the image information of the workpiece during laser cutting, and send the image information to the cutting path analysis module, wherein the image information includes an overhead photo of the workpiece during laser cutting, wherein the overhead photo can show the location of "dust" and "smoke" in the cutting debris; After receiving the image information, the cutting path analysis module compares it with the preset cutting path to obtain evaluation information, and sends the evaluation information to the suction area adjustment module, wherein the preset cutting path is also displayed as an image, and the positions of "dust" and "smoke" in the current cutting debris are quickly obtained by comparing the overhead photo taken with the preset image. After the evaluation information is sent to the suction area adjustment module, the suction area adjustment module generates an area adjustment signal according to the evaluation signal; The process of generating the area adjustment signal is as follows: when the laser cutting machine is cutting the workpiece normally, the cutting head 5 forms a cutting track together with the XY axis slide 3 and the mobile end 4 according to the preset setting. When the image information acquired by the surface parameter acquisition module is consistent with the preset image information, it means that the current cutting action is normal and the "dust" and "smoke" are normally adsorbed through the absorption holes 19 on the main receiving box 16 at the preset position and the openings on the side receiving box 1 8 / side receiving box 2 17, and no signal is generated; When the image information acquired by the surface parameter acquisition module does not match the preset image information, it indicates that the current cutting action is abnormal, and the running track direction of the cutting head 5 is acquired in real time to generate a region adjustment signal, which is simultaneously sent to the motor 27 for regulation; The control action is as follows: the motor 27 is started, the motor 27 drives the moving gear 13 to rotate, and the gear ring 24 meshing with the moving gear 13 completes the rotation through the support rail 15, that is, it also drives the recovery mechanism connected to the gear ring 24 to complete the adjustment of the suction area of ​​the expansion component until it is aligned with the cutting debris discharge area of ​​the workpiece and then stops, thereby forming accurate collection through the position change of the driven component 14 and the expansion component; It should be noted that before laser cutting, by setting the number of driven components 14, the overall adjustment range of the "smoke" and "dust" suction area during the entire laser cutting process can be effectively controlled. For workpieces with simple cutting paths and a narrow coverage area, it is beneficial to reduce the load impact of the driven component 14 on the cutting head 5 during the cutting process, and avoid the problem of deviation in the cutting path caused by excessive weight of the cutting head 5.

[0021] Basic principle: During the laser cutting process, the workpiece to be processed is placed under the cutting head 5. During the laser cutting process, on the one hand, the surface parameter acquisition module is used to determine the specific location where the "smoke" and "dust" are generated, and the recovery mechanism with a variable suction area is combined to complete precise positioning and suction; on the other hand, the area where the "smoke" and "dust" are generated is combined with a variable suction area + a movable displacement suction area to carry out centralized and precise recovery of processing waste chips, thereby improving the processing efficiency of the laser cutting machine.

[0022] Embodiment 2 This embodiment is based on the suction area adjustment module in the first embodiment. After receiving the area adjustment signal, the recovery mechanism performs an execution action to accurately remove the "dust" and "smoke" in the waste recycling process; The driven component 14 includes a ring gear 24 with an annular end-to-end plug-in connection, and the two ends of the ring gear 24 are respectively provided with a plug rod 25 and a socket 26. Adjacent ring gears 24 are connected by plugging the plug rod 25 and the socket 26. A support rail 15 is provided below a plurality of ring gears 24, and a rail rod 22 is provided at the upper end of the support rail 15. A rail groove 23 matching the rail rod 22 is provided below each ring gear 24, and a symmetrically arranged fixing rod 11 is installed at the lower end of the support rail 15, and the fixing rod 11 is connected to the bottom of the movable end 4.

[0023] The motor 27 is started, and the motor 27 drives the moving gear 13 to rotate through the rotating rod 12, and the gear ring 24 meshing with the moving gear 13 completes the rotation through the supporting rail 15. At this time, the expansion box 7 connected to the pneumatic suction source completes the follow-up rotation, and the pneumatic suction source performs the indiscriminate synchronous suction of "dust" and "smoke" through the absorption hole 19 outside the expansion box 7; It also includes a guide plate 20 installed on the upper end of the side receiving box 1 8 and the side receiving box 2 17, a seal 10 is installed on the upper end of the expansion box 7 corresponding to the guide plate 20, and a closed slit 21 for the guide plate 20 to pass through is opened in the middle of the seal 10, the front sides of the side receiving box 1 8 and the side receiving box 2 17 are both open, and the two ends of the side receiving box 1 8 and the side receiving box 2 17 are respectively penetrated by a discharge pipe 1 9 and a discharge pipe 2 18, and the discharge pipe 1 9 and the discharge pipe 2 18 are both connected to a pneumatic suction source; Before the laser cutting of the workpiece, the debris suction range is set in advance according to the preset cutting trajectory of the workpiece, that is, the side receiving box 1 8 and the side receiving box 2 17 are manually pulled out along the closing seam 21 in the seal 10 through the guide plate 20, and the part of the guide plate 20 that is separated from the closing seam 21 is immediately closed without causing air leakage, so that the main receiving box 16, the side receiving box 1 8, and the side receiving box 2 17 form a larger suction area in advance, reducing the difficulty of adjustment during the laser cutting of the workpiece.

[0024] Embodiment 3: This embodiment is based on the contents of Embodiment 1 and Embodiment 2, and forms the following control method: The steps include: Step 1: Before laser cutting the workpiece, the debris suction range is set in advance according to the preset cutting trajectory of the workpiece, that is, the side receiving box 1 8 and the side receiving box 2 17 are manually pulled out along the closing slit 21 in the seal 10 through the guide plate 20, and the part of the guide plate 20 that is separated from the closing slit 21 is immediately closed without causing air leakage, so that the main receiving box 16, the side receiving box 1 8, and the side receiving box 2 17 form a larger suction area in advance; Step 2: During processing: according to the preset cutting head 5, the XY axis slide 3 and the mobile end 4 jointly form a cutting trajectory. When the image information obtained by the surface parameter acquisition module is consistent with the preset image information, it means that the current cutting action is normal and the "dust" and "smoke" are normally adsorbed through the absorption holes 19 on the main receiving box 16 and the openings on the side receiving box 1 8 / side receiving box 2 17 at the preset position, and no signal is generated. When the image information obtained by the surface parameter acquisition module does not match the preset image information, it means that the current cutting action is abnormal, and the running trajectory direction of the cutting head 5 is obtained in real time to generate a regional adjustment signal, and the regional adjustment signal is sent to the motor 27 for regulation at the same time; Step 3: In step 2, the motor 27 is started to drive the moving gear 13 to rotate, and the gear ring 24 meshing with the moving gear 13 completes the rotation through the support rail 15, that is, it also drives the recovery mechanism connected to the gear ring 24 to complete the adjustment of the suction area of ​​the expansion component until it is aligned with the cutting debris discharge area of ​​the workpiece and then stops, thereby forming accurate collection through the position change of the driven component and the expansion component; Step 4: In step 1, before laser cutting, by setting the number of driven components 14, the overall adjustment range of the "smoke" and "dust" suction area during the entire laser cutting process can be effectively controlled. For workpieces with simple cutting paths and narrow coverage, it is beneficial to reduce the load impact of the driven component 14 on the cutting head 5 during the cutting process, and avoid the cutting path deviation caused by excessive weight of the cutting head 5.

[0025] In summary: the recovery mechanism can complete the adjustment of its own suction range and the position change after determining the suction range, and correspond to the position where "smoke" and "dust" are generated. The combination of the two can effectively realize the precise removal of debris during the laser cutting process of the workpiece to be processed; Specifically: the workpiece to be processed is placed under the cutting head 5. During the laser cutting process, on the one hand, the surface parameter acquisition module is used to determine the specific location where the "smoke" and "dust" are generated, and the recovery mechanism with a variable suction area is combined to complete precise positioning and suction; on the other hand, the area where the "smoke" and "dust" are generated is used to combine the variable suction area + the movable shiftable suction area to carry out centralized and precise recovery of processing waste chips, thereby improving the processing efficiency of the laser cutting machine.
