[0002] The multifunctional automatic laser cutting machine is an industrial equipment that uses a laser beam as the main cutting tool. It is combined with a highly automated control system. After clamping the material stably, it can perform cutting, engraving, marking and other processing operations on a variety of materials.

[0003] The patent with the patent announcement number CN220679713U relates to the field of laser cutting technology. The patent discloses an automatic laser cutting machine, including a box body, a five-axis laser cutting robot arm is arranged on the upper part of the interior of the box body, a dust collecting tray is arranged on the outer wall of the five-axis laser cutting robot arm, a hose is fixedly connected to the left side of the dust collecting tray, and a negative pressure fan is fixedly connected to the other end of the hose. The automatic laser cutting machine, through the cooperation between the box body, the five-axis laser cutting robot arm, the dust collecting tray, the hose, the negative pressure fan, the dust collecting box, the workbench, the slide rail, the dust cleaning assembly, the vertical plate, the cylinder, the U-shaped plate, the bolts and the block, the flowing airflow can be blown out through the air pipe to blow away the dust on the workpiece, because the air pipe can be intermittently moved left and right with the shell, the airflow blowing range of the air pipe can be increased, and dead angles are not easy to appear, which is conducive to the all-round cleaning of the workpiece. In addition, the airflow blown out by the air pipe will not generate suction during the process, which is conducive to its long-term stable operation.

[0004] In the above patent, the dust on the workpiece is blown away and cleaned by blowing out through an air pipe. Since the air pipe can intermittently move left and right with the shell, the air flow blowing range of the air pipe can be increased and dead corners are less likely to occur, which is beneficial to all-round cleaning of the workpiece. However, it is difficult to fix the workpiece when cutting it, which may cause the workpiece to shift during welding and lead to cutting failure. Summary of the invention

[0029] When the embodiment is working, the guard plate 14 moves and the push plate 153 starts to move, the push plate 153 moves and pushes the inclined plane block 152 to start moving, the inclined plane block 152 moves and drives the slide plate 151 to start moving, the slide plate 151 moves and drives the collection box 154 to start moving, the collection box 154 moves to collect the welding slag generated during welding, which can effectively prevent the welding slag from splashing into the surrounding environment, thereby reducing the risk of fire, protecting the safety of operators, and preventing the welding slag from being not collected or cleaned up in time and accumulating in the working area, affecting the subsequent work process. After the cutting is completed, the collection box 154 needs to be cleaned When the cutting device 7 stops, the worker holds the handle 155 on the front of the collection box 154, and then presses the push rod 158 so that the push rod 158 pushes the clamping rod 156 to start moving. The clamping rod 156 moves and disengages from the clamping block 157. After the clamping rod 156 disengages from the clamping block 157, the restriction on the collection box 154 is released. Then the handle 155 is pulled to pull the collection box 154 out, and the welding slag collected in the collection box 154 is dumped or recycled. At the same time, limiting the use of the collection box 154 can effectively prevent the welding slag from scattering, keep the welding area clean, and reduce the pollution of the welding slag to the equipment, personnel and other workpieces.

[0030] When the collecting box 154 moves, the L-shaped rod 159 is driven to start moving. The L-shaped rod 159 moves to push the inclined plane block 3 163 to start moving.

After the cutting is completed, it is closed to prevent external dust from entering the fan, thereby extending the service life of the equipment. When the moving door 162 moves, the long rod 168 is driven to start moving. The long rod 168 moves to push the switch button 167 to move at the control end of the motor 2 164 and turn on the motor 2 164, so that the motor 2 164 drives the rotating shaft 165 to start rotating. The rotating shaft 165 rotates to drive the fan blades 166 to start rotating. The rotation of 166 exhausts the gas during cutting, which can reduce the impact of the gas on the laser beam and ensure the stability of the laser cutting process, thereby improving the cutting quality and accuracy. At the same time, it helps to improve the working environment, reduce the concentration of harmful substances, and protect the respiratory system and physical health of the operator. When the fan blade 166 rotates, the gas generated during cutting is drawn out, so that the gas passes through the absorption plate 169. The absorption plate 169 contacts the gas and absorbs most of the harmful substances in the gas, thereby reducing the diffusion of these substances in the working environment, reducing the risk of secondary pollution, and protecting the surrounding environment. When the absorption plate 169 needs to be replaced after absorption, the staff manually pulls out the absorption plate 169, and then cleans the absorption plate 169 or replaces it with a new absorption plate 169.
