Abstract
An ultraviolet curing apparatus includes a housing, a plurality of ultraviolet light emitting diodes (LEDs) arranged in a length direction of the housing, and at least one shutter part coupled to the housing to be movable in the length direction, to cover at least a portion of the plurality of ultraviolet LEDs to limit an irradiation region of ultraviolet light emitted by the plurality of ultraviolet LEDs.
Claims18
An ultraviolet curing apparatus, comprising:
- a housing;
- a plurality of ultraviolet light emitting diodes (LEDs) arranged in a length direction of the housing;
- and
- at least one shutter part, movable in the length direction, coupled to the housing, the at least one shutter part to cover at least a portion of the plurality of ultraviolet LEDs to limit an irradiation region of ultraviolet light emitted by the plurality of ultraviolet LEDs, wherein the at least one shutter part includes:
- a first blocking portion in front of the plurality of LEDs;
- and
- a second blocking portion protruding from the first blocking portion away from the plurality of ultraviolet LEDs and contacting the irradiation region, wherein the second blocking portion includes a groove portion having a linear shape in a front surface of the second blocking portion, in a width direction of the housing.
4 more elements
An ultraviolet curing apparatus, comprising:
- a housing having a first surface in a length direction;
- a plurality of ultraviolet LEDs on the first surface of the housing in the length direction;
- a controller to selectively control an on/off operation of the plurality of ultraviolet LEDs to adjust an irradiation region of ultraviolet light emitted by the plurality of ultraviolet LEDs;
- a driving unit controlled by the controller;
- and
- at least one shutter part to cover at least a portion of the first surface to provide a region in which ultraviolet light is blocked, at least one shutter part being movable in the length direction by the driving unit, wherein the at least one shutter part includes:
- a first blocking portion in front of the plurality of LEDs;
- and
- a second blocking portion protruding from the first blocking portion away from the plurality of ultraviolet LEDs and contacting the irradiation region, wherein the second blocking portion includes a groove portion having a linear shape in a front surface of the second blocking portion, in a width direction of the housing.
6 more elements
An ultraviolet curing apparatus, comprising:
- a linear housing positioned above a stage to support an imprint mold;
- a plurality of ultraviolet LEDs arranged in the linear housing in a length direction of the housing, to irradiate ultraviolet light onto the stage;
- at least one shutter part movably coupled to the linear housing in the length direction, to block a space between the plurality of ultraviolet LEDs and the stage, wherein the at least one shutter part includes:
- a first blocking portion in front of the plurality of LEDs;
- and
- a second blocking portion protruding from the first blocking portion away from the plurality of ultraviolet LEDs and contacting the irradiation region, wherein the second blocking portion includes a groove portion having a linear shape in a front surface of the second blocking portion, in a width direction of the housing;
- a driving unit on the linear housing to move the at least one shutter part in the length direction;
- and
- a controller to selectively control an on/off operation of the plurality of ultraviolet LEDs to adjust an irradiation region of ultraviolet light emitted by the plurality of ultraviolet LEDs and to control a region in which the at least one shutter part blocks the irradiation region by controlling the driving unit.
