Lithium battery storage unit and stacking shelf

Abstract

The utility model discloses a lithium battery storage unit and a stacking shelf. The lithium battery storage unit comprises a frame body; the two groups of battery supporting frames are positioned on the left side and the right side of the frame body; the concave bearing groove is positioned between the two groups of battery supporting frames; the two rails longitudinally extend along the bottom of the bearing groove; an AGV (Automatic Guided Vehicle) for carrying the lithium battery can enter and exit from the bearing groove, and travelling wheels of the AGV can run along the track. According to the lithium battery storage system, when the external stacking machine can carry the AGV to transfer cargoes between the AGV and the lithium battery storage unit, the AGV carried by the stacking machine can leave the carrying mechanism of the stacking machine to enter the bearing groove, and after the lithium batteries are placed on the battery supporting frame, the unloaded AGV returns to the stacking machine, so that the lithium batteries are transferred to the lithium battery storage unit by the AGV; and the operation mode of a traditional stacking machine is changed.

Description

Technical Field

[0001] This utility model relates to the field of lithium battery stacking rack technology, and in particular to a lithium battery storage unit and a stacking rack. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the production scale and storage demand of power lithium batteries, as core components, have experienced explosive growth. Lithium batteries are characterized by their large size, heavy weight, and sensitivity to storage environments, making traditional flat-panel warehousing methods insufficient to meet their efficient storage, retrieval, and management needs. Automated racking systems can significantly improve warehouse space utilization, enabling dense storage in conjunction with automated equipment. Furthermore, the racking structure design provides stable support for batteries, avoiding the risks of compression deformation or electrolyte leakage caused by stacking, making it a mainstream solution in the industry.

[0003] However, as shown in patent CN114313730A, existing storage racks mostly adopt fixed pallet structures and lack dedicated designs for collaborative operation with AGVs. Rack units typically only have simple support surfaces, requiring the AGV to first transfer goods to the stacker crane platform, and then the stacker crane to complete the storage independently. This results in inefficient multiple transfers and is prone to collisions due to positioning deviations during the transfer process, thus restricting the overall operational efficiency and safety of the warehousing system. Utility Model Content

[0004] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a lithium battery storage unit and stacking rack that facilitates AGV entry for placing or retrieving lithium batteries.

[0005] Technical solution: To achieve the above objectives, the lithium battery storage unit of this utility model includes:

[0006] Framework body;

[0007] Two sets of battery support brackets are located on the left and right sides of the frame body;

[0008] A recessed support groove located between the two sets of battery holders; and

[0009] Two tracks extending longitudinally along the bottom of the bearing groove;

[0010] The AGV carrying lithium batteries can enter and exit the carrying tank, and the AGV's wheels can run along the track.

[0011] Furthermore, it also includes:

[0012] The sliding joint components located on both sides of the frame body include:

[0013] The upper sliding joint has a first sliding groove that opens downwards;

[0014] The sliding joint has a second sliding groove that opens upwards;

[0015] A detachable stop pin installed at the end of the sliding assembly.

[0016] Furthermore, the track is U-shaped, which guides the AGV and prevents it from veering off course.

[0017] Furthermore, two support blocks are fixed to the front side of the frame body, and the two support blocks are respectively fixed in front of the two tracks. In actual use, the external stacker crane has a transition track that can overlap to the front of the track. The end of the transition track is supported by the support blocks to ensure that the transition track is erected stably.

[0018] A stacking rack includes a main frame and the aforementioned lithium battery storage units, wherein a plurality of the lithium battery storage units are mounted on the main frame in a square array.

[0019] Furthermore, the main frame includes a connecting plate that connects to the lithium battery storage unit, the connecting plate having an upper edge and a lower edge;

[0020] The lithium battery storage unit has sliding assemblies on both sides of the frame body, the sliding assemblies including:

[0021] The upper sliding part has a first sliding groove that opens downward and engages with the upper edge;

[0022] The sliding joint has an upward-opening second sliding groove that mates with the lower edge;

[0023] A detachable stop pin installed at the end of the sliding assembly.

[0024] In use, the lithium battery storage unit is slid into the main frame body by the cooperation of the sliding assembly and the connecting plate, and is positioned by installing the limit pin, which can realize the quick installation of the stacking rack.

[0025] Beneficial effects: The lithium battery storage unit and stacking rack of this utility model allow the external stacker crane to transfer goods between the lithium battery storage unit and the AGV. When the AGV carried by the stacker crane leaves the stacker crane's transport mechanism and enters the carrying slot, it places the lithium battery on the battery support rack. Then, the empty AGV returns to the stacker crane, realizing the transfer of lithium batteries from the AGV to the lithium battery storage unit, which changes the traditional operation mode of the stacker crane.
