At the same time, during the rotation of the grinding disc 39, with the cooperation of the connecting frame 40, the slag generated during the laser cutting process can be prevented from overflowing, and the cleaning of the board surface can be better achieved; At the same time, the micro pump 31 can operate to suck out the water stored in the water tank 30, and with the cooperation of the connecting pipe, it can be sprayed out through the nozzle on the cooling water pipe 38, so as to achieve cooling of the cutting position, and at the same time, it can prevent the slag generated by the cutting from adhering to the board surface, and at the same time, it can accelerate the cooling of the cut and formed board surface, so as to achieve rapid material unloading.

[0030] S1: Material preparation: Select metal plates and calibrate them to ensure the flatness of the plates. Use a flatness detector to test the flatness of the plates. The thickness difference of the flatness is 0-2mm. S2: Preset the shape of laser cutting: Preset the shape of the cut plate through PLC programming, and adjust the movement process of the horizontal motor 9 and the longitudinal motor 13; S3: Setting the laser intensity and laser cutting distance: according to the thickness of the plate, preset the intensity of the cutting laser, and adjust the distance between the laser head 17 and the plate; S4: Material positioning and feeding: The metal sheet is delivered to the conveying support structure 2, and the metal sheet can be delivered to the cutting area under the rotation of the conveying support structure 2; S5: Scanning calibration: Scan the shape of the loaded sheet material with the installed scanner, and then match the cutting shape; S6: Cutting: During the movement of the horizontal motor 9 and the longitudinal motor 13, the motor 17 can be driven to move and the sheet can be cut according to a predetermined trajectory; S7: Material inspection: After cutting is completed, the size of the cut plate is inspected to determine whether the cut size is qualified.

[0031] The working principle of the present invention is as follows: in order to better cooperate with the moving operation of the laser head 17, the longitudinal motor 13 is operated at the same time, driving the longitudinal screw rod 5 to rotate, which can push the slider 7 to slide along the guide rod 6, thereby realizing the longitudinal movement of the supporting beam 8. When the transverse motor 9 is operated, it drives the transverse screw rod 11 to rotate, which can realize the transverse movement of the load-bearing slide plate 12. With the cooperation of the push cylinder 15, the up and down movement of the laser head 17 can be realized. During the operation of the laser head 17, the movement along the X, Y and Z axes can be realized, and the cutting movement can be realized more accurately. In order to ensure the neatness of the cutting surface and reduce slag, during the extension operation of the push cylinder 15 and the downward movement of the laser head 17, the grinding disc 39 first contacts the plate surface. During the continuous downward movement, the distance between the fixed plate 18 and the movable plate 32 is reduced, thereby compressing the spring 24. The compressed spring 24 can push the movable plate 32 downward, thereby ensuring that the bottom side of the grinding disc 39 can be in close contact with the plate surface, thereby correcting the flatness of the plate during the pressing process and maintaining the flatness of the laser cutting. When the distance between the fixed plate 18 and the movable plate 32 is reduced, the first electrode ring 21 contacts the second electrode ring 23, and the indicator light 20 is powered on. The electrical signal of the indicator light 20 is transmitted to the controller, and the controller issues an operation instruction to the rotary motor 27 and the micro pump 31. When the rotary motor 27 is operating, it can drive the rotary gear 28 to rotate. Under the rotation cooperation of the rotary gear 28, it can drive the gear ring 35 to rotate. During the rotation of the gear ring 35, under the operation cooperation of the connecting frame 40, the plate surface around the cutting point can be polished by the grinding disc 39, which can ensure the cleanliness of the plate surface. At the same time, it can realize follow-up polishing and grinding to avoid slag adhesion, which can reduce the effect of subsequent slag cleaning operations. At the same time, during the rotation of the grinding disc 39, with the cooperation of the connecting frame 40, the slag generated during the laser cutting process can be prevented from overflowing, and the cleaning of the board surface can be better achieved; At the same time, the micro pump 31 can operate to suck out the water stored in the water tank 30, and with the cooperation of the connecting pipe, it can be sprayed out through the nozzle on the cooling water pipe 38, so as to achieve cooling of the cutting position, and at the same time, it can prevent the slag generated by the cutting from adhering to the board surface, and at the same time, it can accelerate the cooling of the cut and formed board surface, so as to achieve rapid material unloading.
