s705, the Z axis rises to the height of Z1, and the X axis and the Y axis start to move to the position of the detection tool;
s706, descending the Z axis to a discharging height Z3, loosening the clamping jaw, and placing the material on the detection tool (17);
s707, raising the Z axis to a detection waiting height Z4;
s708, ejecting the tool jacking device to enable the material to be jacked forwards for limiting, and pressing a spring pressing block attached to the jacking device onto the material while jacking to prevent the material from tilting at one end;
s709, after receiving the jacking signal, the detection software starts to measure the size of the material, and then displays the result on a software interface;
s710, after detection is finished, the jacking cylinder retreats and loosens to drive the spring pressing block to move away;
s711, the Z axis descends to a height Z3, the material taking clamping jaw clamps the materials, and then the materials ascend to a height Z4;
s712, moving the X axis and the Y axis to the coordinates of material taking of the first copying material tray (15) or the second copying material tray (16);
s713, the Z axis is lowered to the height Z2, and the material taking clamping jaw is loosened to put down the material;
s714, lifting the Z axis to the height Z1, and moving the X axis and the Y axis to the next material coordinate;
s715, repeating the steps S703-S713 until the materials are completely measured;
s716, after one material is measured, the rocker arm detection sensor (5) rises to a waiting height;
s717, the detection tool (17) automatically rotates by 90 degrees, so that the detection tool (17) of the next material is positioned right below the rocker arm detection sensor (5);
s718, the rocker arm detection sensor (5) descends to a corresponding detection height;
s719, moving the X axis and the Y axis of the three-axis coordinate manipulator (8) to the first piece coordinate of the next material, and continuing automatic measurement;
s8, when the first copying material tray (15) or the second copying material tray (16) is not full, the system judges whether the material is clamped or not according to whether the rocker arm detection sensor (5) detects data or not, if the material is not clamped, the steps S707-S710 are not executed, and the step S706 is directly jumped to the step S711;
s9, after all the materials are detected, the Z axis of the three-axis coordinate manipulator (8) rises to the height Z1, and the X axis and the Y axis move to the middle position of the equipment;
s10, at this time, the operator can save data, filter, generate report forms and other operations;
s11, after the data operation of the software is completed, taking down the material and loading the material into the original storage position;
and S12, when no other detection is carried out, the detection software is quitted, then the computer is closed, and then the power supply and the air supply of the equipment are closed.
