The invention discloses a vacuum applicator for mobile phones. The vacuum applicator for the mobile phones comprises a bottom plate, a vertical plate, an unwinding shaft, a winding shaft, a horizontal plate, a sensor, a first linear motor, a second linear motor, a hollow rod, a film sucking plate, a sleeve, a sealing plate, a sealing cover, a mobile phone positioning mold, a vacuum pump, a controller and the like, and the sensor is electrically connected with the controller. Film pasting operation of the vacuum applicator for the mobile phones can be finished in closed vacuum space of the sealing cover, therefore, the technical problem that air bubbles exist between a mobile phone film and a mobile phone during film pasting can be solved thoroughly, and film pasting quality can be greatly improved; in addition, the closed space of the sealing cover is small, vacuum pumping time is short, and production efficiency of film pasting is high.
