Abstract

An atypical-molded-body manufacturing device according to the present invention comprises at least one shape output unit comprising a plurality of movable rods provided to be able to move up and down and arranged along a first direction. A driving module transfers a driving force to the movable rods, thereby moving each of the plurality of movable rods to a predetermined height. An atypical curvature is formed by a difference in level configured by the upper end of each of the plurality of movable rods that have moved to the predetermined height.

First claim

The invention claimed is:

1. An atypical-molded-body manufacturing device, comprising:
at least one shape output unit including:
a plurality of movable rods provided to be movable up and down, and arranged along a first direction, each movable rod having threads spirally formed on an outwardly facing circumferential surface of the movable rod, and
a driving module transferring a driving force to the movable rods, thereby moving each of the plurality of movable rods to a predetermined height, the driving module comprising:
a plurality of main gears, each main gear provided to pass therethrough each of the plurality of movable rods, and each having a bore therethrough with internal threads formed to correspond to the threads of each movable rod, wherein rotation of each main gear moves the movable rod in translation relative to the main gear; and
a main actuator transferring a driving force to rotate each main gear, thus moving each movable rod up and down,

whereby an atypical curvature is formed by a difference in level configured by the upper end of each of the plurality of movable rods that have moved to the predetermined height.

2. The atypical-molded-body manufacturing device of claim 1 , wherein the atypical-molded-body manufacturing device comprises at least two of the shape output units, and
the plurality of movable rods of the at least two shape output units is arranged in a grid shape having a second direction that is perpendicular to the first direction.

3. The atypical-molded-body manufacturing device of claim 1 , wherein the driving module further comprises:
an auxiliary gear provided between a pair of neighboring main gears; and
an auxiliary actuator moving the auxiliary gear to cause the auxiliary gear to optionally engage with the main gear.

4. The atypical-molded-body manufacturing device of claim 1 , wherein the main actuator transfers the driving force to any one among the main gears located at the outermost side.

5. The atypical-molded-body manufacturing device of claim 1 , wherein the driving module further comprises:
an auxiliary gear provided to correspond to the main gear;
an auxiliary actuator moving the auxiliary gear to cause the auxiliary gear to optionally engage with the corresponding main gear; and
a gear bar indirectly engaging with the main gear via the auxiliary gear, and
the main actuator rotates the gear bar, thus transferring the driving force to the main gear.

6. The atypical-molded-body manufacturing device of claim 1 further comprising:
a fixing member fixing the movable rod to prevent the movable rod from being rotated.

7. The atypical-molded-body manufacturing device of claim 1 , further comprising:
a first sensor provided on an upper portion of each of the movable rods to detect a height of the movable rod, and configured to measure a lowest height of the movable rod; and
a second sensor provided on a lower portion of each of the movable rods to detect the height of the movable rod, and configured to measure a highest height of the movable rod.

8. The atypical-molded-body manufacturing device of claim 1 , further comprising:
a frame through which the plurality of movable rods pass, the frame having a through hole formed to guide each of the movable rods and fixing the driving module.

9. The atypical-molded-body manufacturing device of claim 1 , further comprising:
a deformation pad seated on the shape output unit, formed to have flexibility, and deformed as the movable rods move up and down, thus defining curvature.

10. The atypical-molded-body manufacturing device of claim 9 , further comprising:
a cap member provided on the upper end of each of the movable rods, and increasing a contact surface with the deformation pad.

11. The atypical-molded-body manufacturing device of claim 1 , further comprising:
an encoder for calculating height data of each of the movable rods.
