[0027] Method of use of the present invention:

[0028] In the initial state:

[0029] The electric push rod 22 is in a retracted state, all the springs 46 on the replacement surface 51 are in a retracted state, the sliders 45 on the replacement surface 51 are attracted by the corresponding electromagnets 44, and the corresponding spare support pins 31 are clamped between each of the clamping blocks 30 on the replacement surface 51. The springs 46 on the removal detection surface 52 are in a normal state, and the sliders 45 are not adsorbed by the electromagnets 44.

[0030] When the present invention is to be used, the user only needs to input the position, size and cutting path of the plate into the console 12 in advance.

[0031] When the present invention is used, an external manipulator or other handling equipment transports the thin plate to the range of the laser cutting bed 11, and when the thin plate starts to be transported, the control console 12 will drive the electric slider under the sliding block 27 and the corresponding electric slider No. 1 34 to start moving, so that the support nails 32 complete the movement, and the support nails 32 are arranged according to the size of the plate and the cutting path to complete the support of the thin plate and the cutting path. The control console 12 will start the corresponding motor No. 1 35, so that the motor shaft of the motor No. 1 35 will drive the fixed block 36 to rotate, and the drive of the motor No. 1 35 will make the corresponding fixed block 36 perpendicular to the path to be cut on the plate, and when the cutting starts When cutting, the control console 12 will drive the corresponding electric slider to drive the No. 4 electric slider 15 to move, and drive the No. 5 electric slider 17 to move, so that the thin plate will start to be cut under the action of the laser cutting component 19. At the same time, after the thin plate falls on the supporting nail 32, the control console 12 will drive the corresponding air pump 39 to start. After the air pump 39 is started, it will suck air through the suction port 42 to absorb the thin plate. At this time, under the action of the control console 12, the No. 2 electric slider 37 on both sides of the cutting path will start and start in the direction away from the cutting path, so as to absorb the thin plate through the suction port 42, and through the cooperation with the No. 2 electric slider 37, the thin plate on the cutting path is propped open. Thereby, the flatness of the thin plate on the cutting path is ensured, and the thin plate is prevented from sagging, warping, deformation, etc. At the same time, because the support nail 32 avoids the cutting path under the drive of the sliding block 27 and the No. 1 electric slider 34, the laser is prevented from directly cutting the support nail 32, which may cause the support nail 32 to be damaged. After a single plate cutting is completed, the external handling equipment transports the cut plate and residual materials, and the control console 12 will drive the electric slider under the sliding block 27 to drive the sliding block 27 to reset. The No. 1 electric slider 34 moves toward the collecting tank 13 under the action of the control console 12. At this time, the control console 12 will drive the No. 3 electric slider 21 to move, and the No. 3 electric slider 21 starts to move to the When the control console 12 moves in the direction of the support nail 32, the camera 48 will detect the state of the support nail 32. If the camera 48 does not detect the image abnormality of the support nail 32, the No. 3 electric slider 21 will be reset. If the camera 48 detects that the support nail 32 is deformed, the camera 48 will transmit a signal to the control console 12. After the control console 12 receives the signal transmitted by the camera 48, the control console 12 will record the current position of the No. 1 electric slider 34. When the No. 3 electric slider 21 slides to the other end, the control console 12 will drive the No. 1 electric slider 34 to move, so that the No. 1 electric slider 34 with damaged and adjacent support nails 32 moves to the same row.The intact supporting nail 32 is staggered with the damaged supporting nail 32, and then the console 12 will drive the third electric slide block 21 to move to just above the damaged supporting nail 32 in the same row. At this time, the corresponding electromagnet 44 on the removal detection surface 52 will be started under the action of the console 12. After the electromagnet 44 is energized, it will adsorb the slide blocks 45 on both sides, so that the clamping block 30 completes the clamping of the damaged supporting nail 32, and then the electric push rod 22 is started under the action of the console 12, and begins to drive the electric push rod 22 to rise, thereby driving the polygonal column 25 to rise, so as to remove the damaged supporting nail 32, and then the No. 2 motor 23 is started, so that the motor shaft of the No. 2 motor 23 will drive the polygonal column 25 to rotate, so that the spare supporting nail 31 of the replacement surface 51 is perpendicular to the ground, and then the console 12 drives the electric push rod 22 to start again, driving the electric push rod 22 to retract and reset, so that the The spare support nail 31 is inserted into the corresponding insertion block 50, so that the spare support nail 31 and the support nail 32 are assembled, and then the electric push rod 22 is started again under the action of the console 12 to complete the extension, and the No. 3 electric slider 21 moves to the end away from the console 12, so that the polygonal column 25 is directly above the collection tank 13, and the console 12 drives the electromagnet 44 on the removal detection surface 52 to cut off the power, so that the slider 45 on the removal detection surface 52 is reset under the action of the spring 46, and the clamping block 30 cancels the clamping of the damaged support nail 32. The damaged support nail 32 loses the clamping of the clamping block 30 and falls into the collection tank 13, waiting for subsequent processing. This reciprocating process completes the replacement of the damaged support nails 32 in batches. The spare spare support nails 31 on the polygonal column 25 need to be manually filled by the user, and the spare support nails 31 are aligned with the limit block 47 and inserted. ,

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
