[0041] For further information, please refer to Figure 1 and Figure 2 The chip removal assembly 2 includes a support frame 21, a locking assembly 22, a heat insulation board 23 and a magnetic assembly 24. The support frame 21 is rotatably installed on the gantry 12. The support frame 21 rotates to drive the magnetic assembly 24 to approach the surface of the base 1. When the magnetic assembly 24 needs to be loaded and unloaded or manually cleaned, the support frame 21 can rotate to drive the magnetic assembly 24 to move, so as to facilitate its processing.

[0042] Among them, the locking component 22 is installed on the support frame 21, and the locking component 22 is used to provide a rotational locking force to the support frame 21 so that the magnetic component 24 can meet the placement state switching during daily placement and installation and cleaning operations. A heat insulation board 23 is provided at the bottom of the support frame 21, and a magnetic component 24 for absorbing metal debris is provided on the rear side of the heat insulation board 23. The heat insulation board 23 is used to block the heat of the magnetic component 24 during ion cutting to increase the service life of the magnetic component 24.

[0043] Among them, the chip groove 3 is arranged at the end of the base 1, and the debris adsorbed by the magnetic component 24 is discharged into the chip groove 3 for collection and treatment, so as to facilitate the staff to quickly and centrally treat the metal debris and improve the convenience of recycling and treatment.

[0044] For further information, please refer to Figure 3 The support frame 21 includes a seat plate 211, a support rod 212 and a bracket 213.

The first mounting block 241 is made of non-ferromagnetic material, and the second mounting block 242 and the chip suction plate 244 are made of ferromagnetic material. When the electromagnetic rod 243 is energized, the magnetic force passes through the first mounting block 242 and the chip suction plate 244 in turn to absorb the metal debris, thereby achieving the purpose of quick collection.

[0049] During implementation, when it is necessary to collect metal debris after cutting the surface of the plate and the surface of the base, when the gantry 12 moves along the length direction of the base 1, the electromagnetic rod 243 is energized to generate magnetic force, so that the metal debris on the surface of the base 1 or the surface of the plate can be quickly absorbed by the chip suction plate 244, and after the metal debris is absorbed, the gantry 12 drives the chip suction plate 244 to move into the chip discharge groove 3, and the electromagnetic rod 243 is powered off to eliminate the magnetic force, so that the debris on the chip suction plate 244 can fall into the chip discharge groove 3.

[0050] Among them, the first mounting block 241 and the second mounting block 242 are internally provided with a mounting groove 245, and the electromagnetic rod 243 is arranged inside the mounting groove 245.

[0052] For details, please refer to Figure 5 The locking column 221 includes a column 2211 coaxially fixed on the support rod 212 and a pin hole 2212 opened on the column 2211. The number of pin holes 2212 is set at two locations, and the setting angle between the two pin holes 2212 is greater than or equal to 90°, so that after the bracket 23 rotates, it can drive the chip suction plate 244 to rotate from the surface of the base 1 to the rear side of the gantry 12, so as to improve the convenience of the staff to clean and maintain the bottom surface of the chip suction plate 244.

[0053] Among them, the control component 222 includes a first frame plate 2221, a pin rod 2222, a cylinder 2223 and a handle 2224.

During implementation, the fixed state of the rotation position of the bracket 23 can be quickly controlled by pulling the pin rod 2222 with the handle 2224.

[0054] During implementation, after the pin rod 2222 slides into the cylinder 2223, a pull plate 2225 is coaxially fixed thereto. There is an installation gap between the bottom surface of the pull plate 2225 and the cylinder 2223, and a spring 2226 is provided between the top surface of the pull plate 2225 and the inner wall of the cylinder 2223. The upper and lower parts of the spring 2226 are respectively fixed to the cylinder 2223 and the pull plate 2225, so that when the pin rod 2222 moves downward, the pull plate 2225 can pull the spring 2226, so that the spring 2226 can provide a reset elastic force for the pin rod 2222.
