[0002] As a basic material, steel sheets occupy a vital position in the application of laser cutting technology. Laser cutting technology is a high-precision and high-efficiency processing method. Laser cutting technology uses high-energy laser beams to quickly and accurately cut metal materials, thereby realizing product customization and processing. It is widely used in metal processing, manufacturing, handicraft production and other fields. In the laser cutting process, the processing speed and cutting efficiency of steel sheets are the core factors to improve production efficiency.

[0043] The working principle of the utility model is as follows: first, the lead screw 57 of the vertical moving mechanism 5 is driven to rotate by the driving component 58, so that the material picking mechanism 7 is lowered to the material frame position, at which time the vacuum suction head 74 is started to absorb the steel plate from the material frame and lift it to a certain height, then the vertical moving mechanism 5 drives the material picking mechanism 7 to move horizontally to the top of the laser cutting machine, at which time the vacuum suction head 74 is turned off, and the steel plate is placed on the workbench 91 of the laser cutting machine for laser cutting operation, after the laser cutting is completed, the vertical moving mechanism 5 is started again, driving the material picking mechanism 7 to move to the initial position, and at the same time the vertical moving mechanism 2 6 moves on the supporting beam 1, driving The transfer mechanism 8 moves to the rear of the discharge mechanism 9.
