[0002] A respirator is a structure that is placed over the user's mouth and nose and is used to connect a breathing device to deliver gas to the user. The respirator usually includes a face cup and an air bag connected to the face cup and used to contact the user's face. In the traditional production process, the face cup and the air bag are fixed by manual gluing, which has low production efficiency. At the same time, during the manual gluing process, the amount of glue is difficult to control, and uneven application can easily cause problems such as glue overflow, poor adhesion, and air leakage. With the development of the economy, more and more respirators are manufactured using automated equipment to improve production efficiency and ensure product quality through automated gluing and gluing. However, in existing automated equipment, when the face cup is placed in the glue brushing groove of the air bag, that is, before the colloid is solidified, it is moved to other workstations. The face cup is prone to shaking, resulting in positional displacement and glue overflow. Utility Model Content
