[0139] Working principle:

[0140] The flat steel is transported from back to front on the conveyor chain mechanism. When the flat steel is transported to the position of the blocking arm assembly of the material distribution and adjustment mechanism, the lifting arm of the lifting mechanism is lifted to stop the flat steel at the rear from being transported forward. At this time, the blocking arm assembly of the material distribution and adjustment mechanism rotates to one side, and the flat steel blocked by the blocking arm assembly continues to be transported forward to the position of the blocking arm of the material blocking and supporting mechanism. Then the supporting plate lifts the flat steel upward to make it separate from the conveyor chain (this can prevent the robot magnet from getting close to the conveyor chain when sucking the flat steel and causing magnetization, thereby avoiding affecting the service life of the conveyor chain). At this time, the robot absorbs the flat steel through the magnet Place the flat steel on the support beam of the lifting and translation device; then the material blocking arm assembly of the material distribution adjustment mechanism returns to its original position, and the lifting mechanism falls to allow the flat steel to continue to be transported forward on the conveyor chain mechanism. Repeat the above operation to stack the flat steel on the support beam in sequence; as the number of flat steel stacking gradually increases, the support beam gradually drops. When the flat steel is stacked to a certain number, the support beam drops to the output roller position and places the flat steel on the output roller. At this time, the support beam moves to one side so that it can rise to the material receiving height, and then the support beam moves back to its original position to restart the material receiving operation. By adjusting the front and rear positions of the material blocking arm assembly of the material distribution adjustment mechanism, it can adapt to flat steels of different widths.
