Abstract

Various embodiments introduce a device for attaching a protection film, the device comprising: a fixing tray including a seating portion on which an electronic device is stably placed; a base portion including a coupling portion to allow the fixing tray to be attached to or detached from the base portion and at least one rail formed along the longitudinal direction or the width direction of the coupling portion; a roller portion which moves along the at least one rail and presses a surface of the electronic device stably placed on the fixing tray; and a hardening portion coupled to the base portion, closing or opening the seating portion of the fixing tray, and emitting ultraviolet rays toward the fixing tray. Other embodiments are also possible.

First claim

The invention claimed is:

1. A device for attaching a protective film, the device comprising:
a fixing tray including:
a seating portion on which an electronic device is seated; and
a first fixing portion and a second fixing portion disposed with the seating portion interposed therebetween, wherein the first fixing portion and the second fixing portion protrude from a surface of the fixing tray and fix a position of the protective film relative to the seating portion;

a base including a coupling portion so as to allow the fixing tray to be attached to or detached from the base and one or more rails disposed along a lengthwise direction or a widthwise direction of the coupling portion;
a roller assembly configured to move along the one or more rails and to press a surface of the electronic device seated on the fixing tray; and
a curing assembly coupled to the base and configured to close or open the seating portion of the fixing tray, the curing assembly comprising a light source configured to emit ultraviolet rays towards the fixing tray,
wherein the first fixing portion includes a first fixing base formed to protrude from the surface of the fixing tray and a first fixing protrusion formed to protrude from the first fixing base,
wherein the second fixing portion includes a second fixing base formed to protrude from the surface of the fixing tray and a second fixing protrusion formed to protrude from the second fixing base, and
wherein the second fixing base has a protruding height higher than a protruding height of the first fixing base.

2. The device of claim 1 , wherein the one or more rails are disposed parallel to each other, with the coupling portion interposed therebetween.

3. The device of claim 1 , wherein the first fixing protrusion includes two or more protrusions, and the second fixing protrusion includes one or more protrusions.

4. The device of claim 1 , wherein the roller assembly includes:
a roller mount configured to move along the one or more rails and protruding from the base;
a roller housing detachably mounted on the roller mount and having an open surface facing the base;
a roller embedded in the roller housing and configured to move towards or away from the base; and
a roller-pressing assembly embedded in the roller housing so as to press the roller towards the base.

5. The device of claim 4 ,
wherein the roller includes a shaft coupled to the roller housing and an elastic portion surrounding the shaft and configured to come into contact with the protective film, and
wherein a central portion of the roller has a diameter smaller than a diameter of opposite end portions of the roller, a change in diameter between the opposite end portions and the central portion based on a cross-sectional shape of the roller corresponds to a surface shape of a cross section of the electronic device cut in a lengthwise direction or a widthwise direction thereof.

6. The device of claim 5 , wherein the elastic portion of the roller is divided in a lengthwise direction of the shaft and is made of materials having different elastic moduli.

7. The device of claim 1 , wherein the curing assembly includes:
a lamp housing formed to correspond to a size of the seating portion of the fixing tray and having an open surface facing the electronic device,
wherein the light source configured to emit ultraviolet rays is disposed in the lamp housing and transmission of the ultraviolet rays is blocked by the lamp housing; and
a power source housing extending from one side of the lamp housing and including therein a controller electrically connected to a power source to control power supplied to the light source and a circuit board on which the controller is mounted, wherein the power source housing is coupled to the base.

8. The device of claim 7 , wherein the curing assembly further includes:
a locking device disposed on a remaining side of the lamp housing, wherein, when the lamp housing closes the seating portion of the fixing tray, the locking device is coupled to the base so as to prevent opening of the lamp housing.

9. The device of claim 7 , further comprising:
a switch disposed in the power source housing, wherein the switch is configured to supply power to the light source when the lamp housing closes the seating portion of the fixing tray and to cut off power supplied to the light source when the power source housing is opened.

10. The device of claim 9 , wherein the controller is configured to perform control such that the power supplied to the light source is cut off after a predetermined time elapses or a temperature inside the lamp housing reaches a predetermined temperature.

11. The device of claim 1 ,
wherein the base includes one or more first fixing portion ridges formed to protrude from the base and disposed along a lengthwise direction of the fixing tray to be parallel to each other in a widthwise direction of the fixing tray, with a place corresponding to a position of the first fixing portion interposed therebetween,
wherein the one or more first fixing portion ridges have a shape in which a degree of protrusion gradually increases and then decreases again along the lengthwise direction of the fixing tray.

12. The device of claim 11 , wherein a maximum degree of protrusion of the first fixing portion ridges corresponds to a degree of protrusion of the first fixing portion.

13. The device of claim 1 ,
wherein the base includes one or more second fixing portion ridges formed to protrude from the base and disposed along a lengthwise direction of the fixing tray to be parallel to each other in a widthwise direction of the fixing tray, with a place corresponding to a position of the second fixing portion interposed therebetween,
wherein the one or more second fixing portion ridges have a shape in which a degree of protrusion gradually increases along the lengthwise direction of the fixing tray.

14. The device of claim 13 , wherein a maximum degree of protrusion of the second fixing portion ridges corresponds to a degree of protrusion of the second fixing portion.
