t2, after the single chip microcomputer (55) receives a signal of circuit conduction of the motor (44), the single chip microcomputer (55) closes a circuit of the servo motor (54), a power output shaft of the servo motor (54) drives the rotating shaft (52) to rotate, the rotating shaft (52) drives the movable frame (5) to deflect, the movable frame (5) deflects towards the direction close to the inside of the material rack (1), at the moment, the second torsion spring (53) exerts force, along with continuous deflection of the movable frame (5), the telescopic frame (6) moves towards the side close to the toughened glass, and until the outer wall of the roller (73) is attached to the toughened glass, so that the roller (73) is pressed and moves towards the direction close to the pressure sensor (76) in the movable groove (72), and when the roller (73) rotates, the steel ball (81) is driven to rotate in the movable hole (8), so that the pressure sensor (76) cannot influence the rotation of the roller (73), the pressure sensor (76) transmits the pressure value to the single chip microcomputer (55) in real time, simultaneously, along with the attachment of the roller (73) and the toughened glass, the movable rod (62) is pressed along the direction of the movable rod and moves towards the inside of the fixed rod (61), at the moment, the compression spring (63) exerts force, when the roller (73) moves to the bottom side of the topmost toughened glass layer, under the action of the compression spring (63), the expansion bracket (6) extends, the outer wall of the roller (73) abuts against the side face of the second layer of toughened glass layer, at the moment, the outer wall of the roller (73) is still attached to the first layer of toughened glass layer, when the roller (73) is attached to the side face of the second layer of toughened glass layer, the verticality of the pressure sensor (76) is small in the moment, at the moment, the single chip microcomputer (55) is excited and closes the circuit of the electric motor (74), and the electric motor (74) drives the roller (73) to rotate, at the moment, the outer wall of the roller (73) gives a friction force to the first layer of toughened glass towards the direction far away from the material rack (1), the toughened glass positioned on the first layer moves towards the direction of the buffer plate (9) after being stressed and completely enters the top surface of the conveyor belt (3) through the buffer of the buffer plate (9), and the toughened glass is conveyed through the conveyor belt (3) until being conveyed to the inside of the glass heating device, so far, the blanking work of the first piece of toughened glass is finished, the blanking process of the following toughened glass is consistent with the above, the toughened glass positioned at the bottommost layer is the smallest displacement, but the fixed plate (51) is U-shaped, so the side surface of the material rack (1) can be used as a change point of the pressure sensor (76) which is vertical, and the toughened glass can be blanked through the process;

t3, after all tempered glass is blanked, the numerical value of the pressure sensor (76) cannot be changed, the motor (44), the servo motor (54), the electric motor (74) and the conveyor belt (3) stop working under the control of the single chip microcomputer (55), the movable plate (42) resets to the vertical direction under the action of the torsion spring (43), the second torsion spring (53) drives the movable frame (5) to reset, the compression spring (63) ejects the movable rod (62) towards the outside of the fixed rod (61), and the telescopic frame (6) is enabled to recover the original length;

t4, through the cooperation use of above each device, can make toughened glass's unloading more convenient to make the time of staff work reduce in high temperature environment, reduce the harm of high temperature environment to the staff health, and simple structure, easily operation.
