Abstract: A film application apparatus includes a first base configured to couple a film material and a second base rotatably coupled to the first base. The first base defines an opening and two through holes on opposite side of the first base, the through holes communicate with the opening. The second base defines a receiving chamber and the receiving chamber is configured for accommodating a work piece. The film application apparatus further includes a pressing component inserted through the first base, the pressing component penetrating through the opening from the two through holes for pressing the film material against to a face of the work piece.

Abstract: A rotation joint includes a base and a rotation member sleeved on the base. An end of the base defines at least one first air guiding hole and a first air outlet. An outer sidewall of the base defines an air guiding groove. The air guiding groove extends around an axis of the base. A bottom wall of the air guiding groove defines a second air guiding hole communicating with the first air guiding hole. The outer sidewall of the base further defines a second air outlet. The first air outlet communicates with the second air outlet. Sidewalls of the rotation member define connecting holes. One of the connecting holes communicates with the second air outlet, while the other connecting holes communicate with the air guiding groove. The present disclosure further provides a multiple air channel workstation using the rotation joint.
