Film adhesion apparatus for a housing of an electronic apparatus

1 . A film attachment apparatus for attaching a film onto a surface of a housing plate of an electronic apparatus, the surface comprising an edge part comprising a curved surface, the film attachment apparatus comprising:

a jig configured to seat and fix the housing plate;

a roller configured to press the film to the housing plate;

a lifting/lowering plate;

a roller carriage rotatably supporting the roller and slidably coupled to the lifting/lowering plate in a direction of the edge part of the housing plate when the jig seats and fixes the housing plate,

a vertical actuator coupled to the lifting/lowering plate and configured to move the lifting/lowering plate to move the roller from above the surface of the housing plate, to which the film is attached, and press the roller to the film;

a horizontal actuator coupled to the lifting/lowering plate and configured to move the roller carriage to move the roller in the direction of the edge part of the housing plate;

wherein the roller carriage comprises an elastic member configured to bias the roller towards the housing plate when the jig seats and fixes the housing plate.

2 . The film attachment apparatus of claim 1 , wherein the film attachment apparatus comprises multiple rollers arranged in parallel, and the horizontal actuator is configured to move the multiple rollers toward multiple edge parts of the housing plate, respectively, the edge parts facing each other.

3 . The film attachment apparatus of claim 1 , wherein a radius of the roller is less than a radius of curvature of the curved surface of the edge part.

4 . The film attachment apparatus of claim 1 , wherein the roller comprises a roll body configured to downwardly press the film to the housing plate, and a journal part having a diameter less than a diameter of the roll body and is configured to transmit, to the roller carriage, a reaction force against downward pressing of the roller, and

wherein the roller carriage comprises a bearing case surrounding the journal part to support a rotation of the roller, and coupled to the elastic member to support the roller.

5 . The film attachment apparatus of claim 4 , wherein the roller comprises two journal parts positioned opposite one another at a terminal end of the roller, and

wherein the roller carriage comprises bearing cases arranged at positions corresponding to the positions of the journal parts.

6 . The film attachment apparatus of claim 4 , wherein the roller comprises a plurality of journal parts formed at opposite ends and a middle of the roller and comprises a roll body divided by one of the plurality of journal parts that is positioned at the middle of the roller, and

wherein the roller carriage comprises bearing cases arranged at positions corresponding to the positions of the journal parts.

7 . The film attachment apparatus of claim 4 , wherein the roll body of the roller comprises a core part positioned at a central part of the roller, and an elastic polymer material surrounding an outer circumferential surface of the core part.

8 . The film attachment apparatus of claim 1 , wherein the roller carriage is detachably fastened to the lifting/lowering plate.

9 . The film attachment apparatus of claim 1 , comprising a release sheet to which the film is attached,

wherein the jig comprises a release sheet guide configured to fix the release sheet in at least one direction on a plane, and

wherein the release sheet includes a guide hole disposed in an area corresponding to the release sheet guide in a perimeter part of the film.

10 . The film attachment apparatus of claim 9 , wherein the guide hole of the release sheet comprises a lengthened hole extending in a direction in which the roller is configured to move based on the film being attached, and

wherein the release sheet includes a perforated line formed by cutting an edge of the lengthened hole in a direction from an inside of the lengthened hole to an outside of the release sheet.

11 . The film attachment apparatus of claim 1 , comprising a jig base positioned below the jig and to which the jig is detachably fastened.

12 . The film attachment apparatus of claim 11 , comprising a jig rail configured to slide the jig base and the jig fastened to the jig base to be inserted into and withdrawn from a lower part of the roller.

13 . The film attachment apparatus of claim 12 , comprising:

a shock absorber configured to contact the jig based on the jig base being inserted into the lower part of the roller and configured to absorb kinetic energy of sliding-motion of the jig base to stop the jig base and absorb a stop impact of the jig; and

a jig sensor configured to recognize the jig inserted into the lower part of the roller,

wherein the jig base comprises a sensor detection-aiding part recognized by the jig sensor.
