Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production equipment, and in particular to an automated material logistics conveying system and production line for a lithium battery factory. Background Art

[0002] With the rapid development of the lithium battery industry, the production scale of lithium battery factories has continued to expand, and the requirements for the logistics and transportation of raw materials have become increasingly higher. At present, the frequency and variety of material transportation in lithium battery factories are diverse, and the requirements for environmental control and transportation efficiency during the transportation of positive and negative electrode raw materials are becoming increasingly higher.

[0003] In the existing technology, due to the limitation of space layout, the raw material warehouse and the battery cell production workshop are generally separated and connected by a corridor. The in and out of the traditional raw material logistics are all on the same side, with one area for inbound and another area for outbound. All the positive and negative materials in the raw material warehouse are sent to the corridor elevator by the ground rail conveyor line. The elevator is connected to the corridor conveyor line and then sent to the battery cell production workshop by the aerial conveyor line. For example, the powder is directly sent to the slurry production area by the aerial conveyor line, and the foil is sent to the ground floor by the aerial conveyor line through the elevator, and then sent to the coating production area by a manual transfer cart.

[0004] However, this traditional material conveying method has the following disadvantages:

[0005] 1) The entry and exit of the raw material warehouse workshop are set on the same side, which occupies a large area of ​​the factory, causing a waste of space and limiting the area of ​​the material sampling area.

[0006] 2) Due to the high environmental requirements for lithium battery production, the traditional method of sharing a roller conveyor line for raw materials will create the risk of cross-contamination of positive and negative electrode materials, which is not conducive to product quality assurance.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] like Figures 1 to 5 As shown, this embodiment provides an automated logistics transportation system for materials in a lithium battery factory, including a raw material warehouse, an aerial corridor 7 and material transportation equipment.

[0047] The raw material warehouse includes a ground storage area 1 and an aerial storage platform 2. The raw material warehouse also includes a negative electrode material storage area 3 and a positive electrode material storage area 4, which are physically separated by a first partition wall 5 to avoid cross contamination.

[0048] The ground storage area 1 is provided with a storage conveyor line 8, and the aerial storage platform 2 is provided with a storage conveyor line 9. The storage conveyor line 8 includes a positive electrode material storage conveyor line 8.1 and a negative electrode material storage conveyor line 8.2, which are respectively connected to the positive electrode material vertical warehouse stacker and the negative electrode material vertical warehouse stacker 6. Figure 2 shown.

[0049] The outbound conveyor line 9 includes a roller conveyor line, an RGV trolley, and a rail conveyor line. The RGV trolley is docked with the raw material warehouse, and the rail conveyor line is docked with the RGV trolley. The roller conveyor line is docked with the raw material warehouse.

[0050] In some optional embodiments of the present invention, the roller conveyor line includes a positive electrode material roller conveyor line 9.1 and a negative electrode material roller conveyor line 9.2.

[0051] The positive electrode material roller conveyor line 9.1 is connected to the positive electrode material vertical warehouse stacker to receive the positive electrode material taken out from the raw material warehouse; the negative electrode material roller conveyor line 9.2 is connected to the negative electrode material vertical warehouse stacker to receive the negative electrode material taken out from the raw material warehouse.

[0052] In some optional embodiments of the present invention, the RGV trolley is used to transfer materials to different track conveyor lines. The RGV trolley includes a positive electrode material RGV trolley 10.1 and a negative electrode material RGV trolley 10.2.

[0053] In some optional embodiments of the present invention, the number of track conveyor lines is the same as the number of material categories.

[0054] In some optional embodiments of the present invention, the track conveying line includes a positive electrode powder track conveying line 11.1, a positive electrode foil track conveying line 11.2, a negative electrode powder track conveying line 11.3 and a negative electrode foil track conveying line 11.4.

[0055] The positive electrode material RGV trolley 10.1 transfers the received positive electrode powder to the positive electrode powder track conveyor line 11.1, and transfers the received positive electrode foil to the positive electrode foil track conveyor line 11.2; the negative electrode material RGV trolley 10.2 transfers the received negative electrode powder to the negative electrode powder track conveyor line 11.3, and transfers the received negative electrode foil to the negative electrode foil track conveyor line 11.4.

[0056] The material conveying equipment includes three different types of forklift AGVs: a first forklift AGV 12 for transporting positive electrode powder, a second forklift AGV 13 for transporting negative electrode powder, and a third forklift AGV 14 for transporting positive and negative electrode foils. These forklift AGVs use laser navigation and travel in AGV conveying channels 15 and 16 according to preset routes. A second partition wall ( Figure 3 and Figure 4 Physical separation (red line in the middle) 17 to prevent cross contamination.

[0057] The forklift AGV's fork arm can dock with the rail conveyor line to receive the positive and negative electrode raw materials from the warehouse. When the forklift AGV arrives at the battery production workshop, its fork arm can dock with the conveyor lines in the positive electrode powder unpacking area, negative electrode powder unpacking area and foil temporary storage area of ​​the battery production workshop to realize the automatic transportation of raw materials.

[0058] In some optional embodiments of the present invention, Figure 3 and 4 As shown, the positive electrode powder track conveyor line 11.1 and the negative electrode powder track conveyor line 11.3 are distributed on the upper and lower sides of the aerial outbound platform 2 (the upper and lower here refer to the upper and lower in the figure, and the actual layout is carried out with reference to the position in the figure), and the positive electrode foil track conveyor line 11.2 and the negative electrode foil track conveyor line 11.4 are arranged in the middle of the aerial outbound platform 2, that is, between the positive electrode powder track conveyor line 11.1 and the negative electrode powder track conveyor line 11.3. In this way, the positive and negative electrode powders can be isolated to the greatest extent to prevent cross contamination.

[0059] like Figure 4 As shown, in some optional embodiments of the present invention, the positive electrode material RGV trolley 10.1 is arranged between the positive electrode material roller conveyor line 9.1 and the positive electrode powder track conveyor line 11.1 and the positive electrode foil track conveyor line 11.2. The positive electrode material RGV trolley 10.1 transfers the positive electrode material from the positive electrode material roller conveyor line 9.1 to different track conveyor lines according to the column.

[0060] The arrangement of the negative electrode material RGV trolley 10.2, the negative electrode material roller conveyor line 9.2, the negative electrode powder material rail conveyor line 11.4, and the negative electrode foil material rail conveyor line 11.3 is similar to that of the positive electrode material conveyor, and will not be repeated again.

[0061] In order to prevent cross contamination of positive and negative electrode materials, mainly cross contamination of powder materials, the first partition wall 5 is extended between the positive electrode material RGV trolley 10.1 and the negative electrode material RGV trolley 10.2.

[0062] In such Figure 4 As shown, in some optional embodiments of the present invention, the second partition wall 17 extends between the positive electrode powder track conveying line 11.1 and the positive electrode foil track conveying line 11.2 to physically isolate the positive electrode powder from other materials to the greatest extent.

[0065] The upper layer includes the positive electrode slurry feeding area 18 and the negative electrode slurry feeding area 19, and the lower layer includes the positive electrode coating area 20 and the negative electrode coating area 21. The aerial delivery platform of the raw material warehouse is at the same elevation as the upper layer of the battery cell production workshop, and is connected by an aerial corridor 7, so that the distribution path of each material is as short as possible.

[0070] In order to transport the foil from the upper layer to the coating area in the lower layer, the battery cell production workshop is provided with a positive electrode foil elevator 22 and a negative electrode foil elevator 23.

[0071] After the positive electrode powder is unpacked, workers transport it to the positive electrode slurry feeding area 18 to prepare for production; after the negative electrode powder is unpacked, workers transport it to the negative electrode slurry feeding area 19 to prepare for production.

[0072] like Figure 3 As shown, in some optional embodiments of the present invention, the positive electrode slurry feeding area 18 and the positive electrode powder unpacking area are both located above the battery production workshop, and the negative electrode slurry feeding area 19 and the negative electrode powder unpacking area are both located below the battery production workshop, where the above and the below refer to Figure 3 For the actual layout, refer to the positions in the figure.

[0073] like Figure 1 As shown, in some optional embodiments of the present invention, the positive electrode coating area 20 is located above the battery production workshop, and the negative electrode coating area 21 is located below the battery production workshop, where the above and the below refer to Figure 1 For the actual layout, refer to the positions in the figure.

[0074] For example Figure 1 and Figure 3 As shown, the battery cell production workshop separates the lithium battery positive and negative electrode production workshops by walls, thus ensuring cross contamination during the production process of lithium battery positive and negative electrodes.

[0075] Example 3

[0076] In this embodiment, the specific process of material transportation is described in detail:

[0077] 1. Warehousing process:

[0078] The raw materials enter the raw material warehouse through the warehouse conveyor line 8 of the ground warehouse area 1. The warehouse conveyor line 8 is divided into two independent warehouse entrances. The positive electrode material warehouse conveyor line 8.1 is connected to the positive electrode material vertical warehouse stacker, and the negative electrode material warehouse conveyor line 8.2 is connected to the negative electrode material vertical warehouse stacker 6. The materials are stored in the positive electrode material storage area 4 and the negative electrode material storage area 3 respectively through the stackers.

[0079] 2. Outbound process:

[0080] When it is necessary to ship out of the warehouse, the stacker takes the materials out of the storage area and places them on the outbound conveyor line 9 of the aerial outbound platform. Specifically, the taken out materials are sent to the roller conveyor line, which transports the materials to the RGV trolley, which transports them to the corresponding track conveyor line according to the material type.

[0081] The positive electrode powder is taken out from the positive electrode raw material storage area 4 by a stacker, and then placed on the positive electrode material roller conveyor line 9.1 connected to the second-floor aerial outbound platform, and then transported to the positive electrode powder track conveyor line 11.1 at the other end by the positive electrode material RGV trolley 10.1.
