本发明公开了一种增湿器耐高温胶封装工艺及封装设备,属于燃料电池技术领域。针对现有中空纤维膜增湿器封装工艺依赖手工预堵易导致膜孔堵塞、单一胶种难以兼顾密封性与爬膜控制、离心排气效率低且振动设备易损伤膜丝的问题,提出一种无需预堵的梯度注胶与低频振动协同工艺。该工艺先注入2–4mm厚低粘度胶形成50–60mm爬膜长度的密封屏障,再在其上注入40–50mm厚主密封胶,并在每次注胶后30秒内施加4–10Hz、3分钟的垂直低频振动以排气;配套设备采用弹簧‑橡胶复合减震结构与高精度承载台,确保振动方向可控、胶层均匀。本发明实现零堵塞、零气孔,单班产能超200件,适用于燃料电池系统中空纤维膜增湿器的高效可靠封装。
