The three-dimensional storage rack 10 is used to place the crystal rods 50, including a horizontal bracket 11 and a vertical bracket 12. The horizontal bracket 11 and the vertical bracket 12 are fixedly connected to form a grid-shaped storage position, and a placement plate 13 is installed at the bottom of each storage position. In order to facilitate transportation and not directly contact the crystal rod 50, a tray 14 is provided on the placement plate 13, and the tray 14 is used to place the crystal rod 50. The tray 14 corresponds to the storage position one by one. An information QR code is provided on the tray, which is not shown in the figure. The specific position of the tray is recorded on the information QR code. In order to prevent the tray 14 from sliding on the placement plate 13, an anti-skid pad 15 is fixed on the placement plate 13. The material of the anti-skid pad 15 is not limited to silicone or rubber. During the transportation process of the crystal rod 50 in and out of the warehouse, the tray 14 is transported together with the crystal rod 50. The stacking device 40 is arranged between the three-dimensional storage racks 10, and is used for the storage and out of the crystal rod 50.

[0047] A storage buffer station 20 is provided at one end of the three-dimensional storage rack 10. When the crystal ingot 50 reaches the storage port, an external robot arm places the crystal ingot 50 on the tray 14 on the storage buffer station 20. A handheld PDA is used to scan the single crystal serial number and the information QR code on the tray 14 for information binding. The stacking device 40 places the tray 14 and the crystal ingot 50 together on the corresponding storage position of the tray 14.

[0048] Preferably, the storage buffer station 20 is a straight conveyor line body, which can be set in multiple layers. In this embodiment, the storage buffer station 20 is set in two layers, the upper layer can be used for pallet 14 buffering, and the lower layer is used for storage buffering. When the crystal rod 50 arrives at the storage port, the external robot arm places the pallet 14 at the end of the lower conveyor line body, clamps the crystal rod 50 to the pallet 14, manually binds the information, and the conveyor line body transports the crystal rod 50 and the pallet 14 to one end close to the three-dimensional warehouse rack 10 for buffering, waiting for the stacking device 40 to enter the warehouse.

[0049] The other end of the three-dimensional warehouse rack 10 is provided with a warehouse-out cache station 30, which can be docked with an AGV trolley for automatic warehouse-out of the crystal rod 50. Preferably, the warehouse-out cache station 30 is a straight conveyor line body, the height of which is the same as that of the AGV trolley, and a plurality of warehouse-out cache positions are provided on the straight conveyor line body. After receiving the warehouse-out information, the stacking device 40 transports the corresponding pallet 14 and the crystal rod 50 to the straight conveyor line body and waits for warehouse-out. After the AGV trolley docks with the warehouse-out cache station 30, the straight conveyor line body transports the crystal rod 50 and the pallet 14 that need to be shipped out to the AGV trolley. After the AGV trolley transports the crystal rod 50 to the next process, it sends the pallet 14 back to the warehouse entrance, and the external robotic arm places the pallet 14 on the upper layer of the warehouse-in cache station 20 for caching, and the pallet 14 can be recycled.

[0050] Preferably, in order to ensure the docking accuracy between the AGV and the outbound buffer station 30, a magnetic stripe guide 31 is provided at the docking end between the outbound buffer station 30 and the AGV to achieve safe outbound transportation of the crystal rod 50.
