[0002] Curing ovens play a vital role in industrial production, particularly in the fields of electronics, metal processing, and resin curing. Their primary function is to enhance the bonding stress between materials through heating and constant temperature treatment, completing the curing process of the workpiece. With the continuous advancement of technology, the design and process of curing ovens are also being continuously optimized. Among these, the pneumatic connection technology for rotating workpieces within the curing oven has become the key to improving production efficiency and workpiece quality.

[0003] In the curing furnace, the workpiece being rotated and cured needs to be pressurized inside during the curing process to meet the process requirements. When filling the air pressure, the air nozzle of the air filling pipe presses against the workpiece to pressurize its interior.
