[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, people pay more attention to personal health and health, and the market has higher requirements for the automation, stability and production efficiency of mask production equipment. When the mask is in use, the nose wire clip is used to clamp the bridge of the nose to achieve full fit between the mask and the user's face. However, most of the nose wire clips on the market are made of bendable metal sheets. It is extremely uncomfortable to clamp the bridge of the nose by the metal sheet nose wire clip for a long time. In severe cases, the bridge of the nose may even be injured. In order to solve this problem, it is necessary to add a sponge strip to the mask, and clamp the sponge strip by the nose wire clip so that the sponge strip is attached to the bridge of the nose. For the operation of attaching the sponge strip to the mask fabric, in the related technical field of sponge strip attachment on the existing mask, manual installation or manual and mechanical hybrid semi-automatic installation is adopted; the effects brought by this installation method are: first, the installation work efficiency is low and the labor cost is high, and second, the quality of the mask product cannot be effectively guaranteed, especially the inaccurate position of the sponge strip will affect the sealing of the mask. Therefore, how to improve the working efficiency and fitting position accuracy of the sponge strip on the mask fabric and improve the degree of production automation are the directions that technical personnel in this field need to work on.
