The invention provides a method and a device for manufacturing a hollow fiber membrane module. The present invention, by penetrating the hollow fiber membrane wires into the steel wires and performing rigidization treatment, greatly improves the rigidity of the hollow fiber membrane wire module, thereby avoiding the bending and deformation of or the damage of hollow fiber membrane wire module due to a small force during the production process, which greatly improves the production efficiency of the hollow fiber membrane module. The device of the present invention is used to achieve the above-mentioned method.
