When the film-sticking rotating motor works, the film-sticking rotating motor drives the shell positioning seat shaft 47 to rotate through the film-sticking driving belt wheel, the film-sticking synchronous belt and the film-sticking driven belt wheel, the shell positioning seat shaft is installed on the film-sticking sliding seat through a bearing, and the shell positioning seat 46 is installed on the shell positioning seat shaft. A positioning cavity 461 is arranged on the housing positioning seat 46, and the axis of the positioning cavity of the housing positioning seat is parallel to the axis of the vacuum shaft.

According to the structure, the belt material disc wound with the belt material is arranged on the disc component, and the belt material on the belt material disc passes through the belt material cutter mechanism and the stripping mechanism through the guiding of the belt material guiding wheel set. When the vacuum shaft positioning device works, a workpiece is arranged on the shell positioning seat, the workpiece is positioned in the positioning cavity of the shell positioning seat, the workpiece is provided with a cavity, the cavity is provided with an opening, the opening faces the vacuum shaft, then the film pasting vertical drive is started, the film pasting sliding seat is driven to move through the film pasting vertical drive, and the central axis of the cavity of the workpiece is coaxial with the central axis of the vacuum shaft; then start the base stock drum drive, inhale membrane rotary drive and pad pasting rotary drive, let the base stock drum rotatory and drive the base stock winding on the base stock drum, let the vacuum shaft rotatory, let the casing positioning seat rotatory. When the band material that is hauled is in the process cutter mechanism below, according to the length of pad pasting, the cutter drive drives the cutter slide downstream, the cutter slide drives the cutter downstream, utilize the cutter to cut off the pad pasting on the band material, when the band material reaches and peels off the knife edge department, the pad pasting on the band material is peeled off with the base stock, the base stock twines on the base stock drum under the guide effect of base stock direction wheelset, the base stock drum passes through the drive of address drum wheel drive, thereby realize the continuous conveyor of band material.
