The operation process of the present embodiment is as follows: after the AGV trolley is in signal butt joint with the equipment, the belt 1-1-1 of the feeding conveying unit 1-1 in the figure 2 starts to rotate, a material tray on the AGV trolley is dragged into the equipment through friction force until the material tray is blocked by a tail end limiting metal plate 1-1-4, the material tray is detected by a sensor, and after the material tray reaches a specified position, the feeding regulating unit in the figure 3 regulates the material tray entering the equipment mainly through the clamping metal plate 1-2-1, so that the material tray is ensured to be in a central position. When the charging tray flows into the equipment, the device automatically clamps the equipment, so that the charging tray is positioned in the central position of the equipment. After the regulation action is finished, the jacking cylinder 1-1-3 shown in the figure 2 starts to return to the initial state from the original jacking state, the material tray falls onto the carrier plate 2-3 of the transfer unit shown in the figure 4 from the feeding conveying unit, the material tray is about to leave the feeding position 1 and goes to the buffer position 3, and when the material tray reaches the buffer position 3, the feeding position 1 can receive the material tray sent by the AGV again.

The pallet transfer unit shown in fig. 4 is driven by rodless cylinders 2-4 to transfer the trays from the feeding position to the buffer position. After reaching the buffer position, the jacking cylinder 3-1-2 of the middle jacking device shown in fig. 5 starts to ascend, the tray is separated from the carrier plate 2-3 of the transfer unit, and the rodless cylinder 2-4 of the transfer unit returns to the initial state. The middle lifting cylinder 3-1-2 returns, and the tray falls onto the supporting plate 2-1 of the transfer unit, which is also the interface of the next series of work. The supporting plate lifting butt-clamping device shown in fig. 6 is driven by the clamping cylinder 3-2-2 to move oppositely (the direction shown in the figure is left-right relative movement) to regulate the material trays, at this time, the separating clamping strips 3-2-4 are positioned between the lowest layer and the penultimate tray (a supportable short edge exists in each material tray and a gap exists between the material trays), the lifting cylinder 3-2-3 moves upwards along with the separating clamping strips 3-2-4, the separating clamping strips touch the short edge of the penultimate tray, the rest material trays except the material tray at the bottommost layer are supported by the force, so that the separation process of the tray at the bottommost layer and the rest material trays is completed, and then the lifting cylinder 3-1-2 of the lifting device of the intermediate supporting plate moves upwards to receive the material tray lifted by the action of the separated clamping strips. When the pallet lifting and clamping device shown in fig. 6 detects that the tray is separated, the rodless cylinder in the transfer unit moves again, namely the tray is sent to the working position 4, the lifting unit shown in fig. 7 starts to move upwards from the initial state, and when the difference between the lifting unit and the lower surface of the tray is about 5mm, the transfer pallet (2-1) of the transfer unit is driven by the cylinder 2-2 to move backwards, and the tray falls onto the lifting unit. After receiving the material tray, the lifting unit starts to ascend (and the transfer unit returns) until the material tray is transported to the receiving height, meanwhile, the four cylinders 4-2-1 of the lifting regulation unit shown in the figure 8 simultaneously move to drive the regulation panels 4-2-2 to position and clamp the material tray, after the positioning action is finished, the upstream equipment is waited to discharge the material tray, and after the discharge is finished, the material tray is not discharged from the equipment, but descends to the height below the transfer unit through the action of the lifting unit. Now all the other trays in the buffer position are still in a suspended state on the clamping strip, after the transfer unit returns, the middle jacking device starts to ascend, the supporting plate lifting butt-clamping device starts to descend, all the other trays can fall on the jacking supporting plate 3-1-1 shown in the figure 5, after the jacking supporting plate receives the trays, the jacking cylinder 3-1-2 descends, the trays fall on the supporting plate of the transfer unit again, and therefore the state of the first feeding plate is returned. The action flow design is an optimal scheme selected from a plurality of schemes through comparison, and the action flow has the great advantage that each separation action is completely consistent, so that too many states do not need to be set on software, and the workload is greatly reduced. After a material tray on the lifting unit is fully filled with materials, the lifting unit can automatically descend to a set position, the material tray can be in contact with a belt (5-2) of the discharging conveying unit shown in fig. 9, the material tray moves outwards, meanwhile, a stopping device 5-3 is further arranged at an outlet of the discharging conveying unit, the purpose is to prevent an AGV from not reaching the machine, after the AGV reaches the machine, a stopping cylinder of the stopping device can descend, the material tray is conveyed to the AGV, and the AGV receives the material tray and then moves to an appointed position according to a set track. The material on the production line is conveyed to a specified position through the blanking machine without the participation of manpower.
