The invention discloses a full-automatic multi-blade saw with a scanning function and a using method of the full-automatic multi-blade saw, and relates to the technical field of multi-blade saws, the full-automatic multi-blade saw comprises a
workbench, a collecting box and a control console, the collecting box is installed in the middle of the top of the
workbench, and the control console is installed on one side of the collecting box. By means of a high-precision sensor in the scanning module, size and shape data of a plate can be accurately obtained, a
cutting instruction is automatically generated through the main processor module and the PLC according to the obtained data, a first electric
telescopic cylinder in the executing mechanism is controlled, the heights of all sets of saw blades needing to be used are adjusted, and the
cutting efficiency is improved. And through arrangement of a first
servo motor, a bidirectional lead screw, a mounting groove, a through hole, a fixing rod, a moving block and a moving groove, the position of the saw blade can be adjusted while the stability of the saw blade is guaranteed, then the working efficiency and the
cutting precision are improved, and waste of plates is reduced.
