[0003] Although traditional metal cutting technology can meet general cutting needs, it still has problems such as insufficient cutting accuracy, low efficiency and improper waste treatment when processing CT machine shells, which may affect the quality and production cost of the final product. The CT machine shell is usually made of high-strength metal sheets of varying thicknesses. Highly precise control is required during the cutting process to ensure that the size and structural accuracy of the shell meet the design requirements.

Through the combination with the computer control system, the unloading module can intelligently allocate and stack the cut workpieces according to their size and category.

[0037] Working principle: First, the component drawings of the CT machine are imported into the computer body 10. After analysis, the linear guide rail 202 is started to drive the movable seat 203 to move to the left. After moving to the top of the block 3 to be cut, the hydraulic cylinder 204 is started to drive the beam 205 to descend, so that the suction cup 208 is in contact with the plate to be cut, and then the cylinder 207 is started, so that the inside of the suction cup 208 is in a negative pressure state, and then the suction cup 208 and the plate to be cut are fixed, and then the linear guide rail 202 is started to drive the movable seat 203 to move to the right to a suitable position, so that the plate to be cut is placed on the placement rack 501 through the hydraulic cylinder 204, and then the suction cup 208 is separated from the plate to be cut by releasing the cylinder 207.

[0038] Secondly, the plate to be cut is driven by two linear guide rails 503 to move the placement rack 1 501 precisely in a linear direction to the inside of the protective frame 8, ensuring that the metal plate is stably supported and positioned. At this time, the placement rack 2 502 is moved to the outside of the protective frame 8 through the linear guide rail 3 505 to receive the plate to be cut, and the placement rack 1 501 is ready for cutting, which can effectively avoid downtime during loading and unloading and cutting, and ensure the smoothness and efficiency of the production line.

[0039] Next, when the metal sheet is in place, the cutting assembly 6 starts working, and the laser cutter 607 moves precisely through the linear guide rails 4 601, 5 603 and 6 605 to efficiently cut the metal sheet along a predetermined path. The power, speed and other parameters of the laser cutter 607 are adjusted in real time in the computer control system through the CNC module, and the sensor 11 is responsible for real-time monitoring of the offset and temperature changes of the laser beam, and feeding back the data to the computer system to ensure the accuracy and quality of the cutting.

[0040] At the same time, during the cutting process, the screening component 7 starts to work, and the rotating shaft 704 is driven to rotate by starting the motor 703, so that the cam 705 can reciprocately knock on the baffle 709, and the connecting rod 707 is driven to move upward through the baffle 709, thereby driving the slider 710 to move upward inside the slide groove 711, and then driving one side of the screen 702 to move upward, and the baffle 709 is reset through the elastic action of the spring 708, and then the baffle 709 is reciprocated by the reciprocating knocking of the cam 705, so that the screen 702 can vibrate, and the fallen larger metal parts or waste and smaller slag or debris are screened. The screen 702 will separate the larger metal parts and waste from the smaller slag, so that the smaller slag or debris enters the storage box 1 712, and the larger metal parts or waste enters the storage box 2 713, which is convenient for the classification and storage of the screened materials.

[0041] In addition, during the cutting process, a large amount of smoke and dust will be generated, and the smoke exhaust and dust removal component 9 will be started. The pressure pump 902 will transport the exhaust gas to the filter box 901 through the pipeline. The activated carbon absorbs harmful gases in the exhaust gas and discharges clean air to the outside.

[0042] Finally, the cut workpieces are automatically unloaded by the loading and unloading assembly 2 and sent to the post-cutting placement block 4 for stacking.

[0043] 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.
