Electrode sheet oven drying apparatus, battery production device, and electrode sheet oven drying method

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;
• 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;
• a circulating air pipe with one end connected to the oven drying chamber and another end connected to the oven drying assembly;
• a fresh air pipe with one end connected to the circulating air pipe and another end communicated to outside;
• a second air volume regulating valve installed in the fresh air pipe;
• and
• a pressure difference detection module communicatively connected to the control module, the pressure difference detection module being configured to detect an air pressure in the oven drying chamber to control the second air volume regulating valve;
• wherein the pressure difference detection module is provided with a first detection end and a second detection end, the first detection end extending into one end of the air discharge pipe connected to the oven drying chamber, the second detection end extending into one end of the circulating air pipe connected to the oven drying chamber, and the pressure difference detection module being configured to detect an air pressure difference between the end of the air discharge pipe connected to the oven drying chamber and the end of the circulating air pipe connected to the oven drying chamber.
