Abstract

An electrode sheet oven drying apparatus includes an oven provided with an oven drying chamber, an oven drying assembly positioned in the oven drying chamber, an air discharge pipe connected to the oven drying chamber, a first air volume regulating valve installed at one end of the air discharge pipe connected to the oven drying chamber, a humidity detection module installed in the oven drying chamber and configured to detect a humidity in the oven drying chamber, and a control module communicatively connected to the humidity detection module and configured to regulate the first air volume regulating valve according to the humidity in the oven drying chamber.

Claims (30)

1 . An electrode sheet oven drying apparatus, comprising:

an oven with an oven drying chamber;

an oven drying assembly positioned in the oven drying chamber;

an air discharge pipe connected to the oven drying chamber;

a first air volume regulating valve installed in the air discharge pipe;

a humidity detection module installed in the oven drying chamber, and configured to detect a humidity in the oven drying chamber; and

a control module communicatively connected to the humidity detection module, and configured to regulate the first air volume regulating valve according to the humidity in the oven drying chamber.

2 . The electrode sheet oven drying apparatus according to claim 1 , wherein:

the oven drying assembly comprises an upper compartment and a lower compartment arranged apart, a plurality of first air nozzles being arranged on one side of the upper compartment facing the lower compartment, a plurality of second air nozzles being arranged on one side of the lower compartment facing the upper compartment; and

the humidity detection module is positioned between the first air nozzles and the second air nozzles.

3 . The electrode sheet oven drying apparatus according to claim 1 , further comprising:

a circulating air pipe with one end connected to the oven drying chamber and another end connected to the oven drying assembly; and

a fresh air pipe with one end connected to the circulating air pipe and another end communicated to outside.

4 . The electrode sheet oven drying apparatus according to claim 3 , further comprising:

a second air volume regulating valve installed in the circulating air pipe.

5 . The electrode sheet oven drying apparatus according to claim 3 , further comprising:

a second air volume regulating valve installed in the fresh air pipe.

6 . The electrode sheet oven drying apparatus according to claim 5 , further comprising:
