Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing, and more specifically to a device for caching battery materials. Background Art

[0002] Lithium-ion batteries have the characteristics of high specific energy, low self-discharge, high operating voltage, environmental friendliness and no memory effect, and have increasingly broad applications.

[0003] The main components of lithium-ion batteries include electrolyte, isolation materials, positive and negative electrode materials, etc., and positive electrode materials account for a large proportion. Therefore, the requirements for positive electrode materials of lithium batteries are getting higher and higher, especially the requirements for water content in positive electrode materials are getting stricter and stricter. The water content in the positive electrode material not only has a certain impact on the manufacturing process of lithium batteries, but also greatly affects the cycle life of lithium batteries.

[0004] At present, when lithium-ion batteries are produced, the positive electrode materials are not well cached after purchase or before production, making the positive electrode materials susceptible to moisture. When the positive electrode materials are used, they need to be dried by a heating device before use, which requires a lot of manpower, thus greatly affecting the production efficiency of lithium-ion batteries. Utility Model Content

[0007] Generally, battery materials are in the form of coils before use, and the battery materials can be hung on rollers to facilitate the caching of battery materials. When the box door is closed, an external dry gas device introduces dry gas from the air inlet assembly through a pipeline, so that the internal environment of the box is dry, thereby ensuring the dryness of the battery materials before use, greatly improving the production efficiency of lithium-ion batteries. In addition, the rack is placed inside the box, which is convenient for the replacement of the rack. At the same time, several hanging rollers are detachably connected to the hanging racks, which can facilitate the replacement or installation and disassembly of the hanging rollers.

When taking, the forklift arm of the forklift can be used to support the battery materials, and the forklift can be moved to realize the taking and transportation of the battery materials.

[0009] The end of each hanging roller away from the hanging frame is provided with a limiting structure to prevent the battery material from slipping out of the hanging roller.

[0010] The limiting structure is a raised portion, which is formed by radially extending from the end of the hanging roller away from the hanging bracket.

[0011] The protrusion is formed by the end of the hanging roller away from the hanging frame extending radially upward. When the battery material is hung on the hanging roller, the protrusion can directly limit the end of the battery material to prevent the battery material from slipping out.

[0014] The air inlet assembly includes an air inlet and an air inlet cover; the air inlet is opened on the top of the box, and the air inlet cover can be rotatably arranged on the box and matched with the air inlet. When the device is not in use, the air inlet cover can be rotated to cover the air inlet; when the device is in use, the air inlet cover can be rotated to open the air inlet, and the external dry gas supply device extends into the box from the opened air inlet through a pipeline, and the air inlet is sealed.

[0015] The box body is also provided with an air outlet assembly; the air outlet assembly includes at least two air outlets and an air outlet cover member having the same number as the air outlets; the air outlets are provided at the bottom of the box body, and the air outlet cover member can be rotatably provided on the box body and matched with the air outlets. The utility model can selectively open one or more air outlets according to actual needs, so that the dry gas flows out from the air outlet gap and one or more air outlets, so as to increase the circulation speed of the dry gas.

[0016] The air inlet is located at the top of the box body and close to one end of the box body; the air outlet is located at the bottom of the box body and close to the other end of the box body. This design allows dry gas to flow from one end of the box body to the other end to ensure a dry environment inside the box body.
