Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery production equipment, and more specifically relates to a constant temperature multi-support rod assembly transfer cabinet. Background Art

[0002] Some raw materials for lithium battery electrode sheets have certain requirements for the environment during storage and transportation. For example, graphite or silicon-based materials are sensitive to humidity in the air and need to be stored and transported in a dry environment to avoid performance degradation.

[0003] In view of this scenario, the prior art provides a variety of constant temperature and humidity chambers. However, a common constant temperature and humidity chamber can only hold one roll of electrode sheet raw material.

[0004] For some electrode sheet processing techniques, the electrode sheet raw materials need to be pre-cut to a smaller size. The volume of the electrode sheet coil after cutting is significantly reduced compared to the electrode sheet raw materials before pre-cutting. The pre-cut electrode sheet coil cannot be stored in the existing constant temperature and humidity chamber. On the one hand, it reduces the space utilization rate. On the other hand, some measures used to maintain the stability of the electrode sheet raw materials are no longer suitable for the cut electrode sheet coil. If these constant temperature and humidity chambers continue to be used, there may be safety hazards. Utility Model Content

[0036] The technical solution of the utility model is further described in detail below through embodiments and in combination with the accompanying drawings, but the utility model is not limited to the following embodiments.

[0037] Some raw materials for lithium battery electrode sheets have certain requirements for the environment during storage and transportation. For example, graphite or silicon-based materials are sensitive to humidity in the air and need to be stored and transported in a dry environment to avoid performance degradation.

[0038] In view of this scenario, the prior art provides a variety of constant temperature and humidity chambers. However, a common constant temperature and humidity chamber can only hold one roll of electrode sheet raw material.

[0039] For the processing technology of some electrode sheets, the electrode sheet raw materials need to be pre-cut to a smaller size, and the volume of the electrode sheet coil 2 after cutting is greatly reduced compared with the electrode sheet raw materials before pre-cutting. The pre-cut electrode sheet coil 2 cannot be stored in the existing constant temperature and humidity chamber, which on the one hand reduces the space utilization rate, and on the other hand, some measures used to maintain the stability of the electrode sheet raw materials are no longer suitable for the cut electrode sheet coil 2.
