Referring to FIG. 1, a three-dimensional curved surface displaying apparatus 1 according to an embodiment of the present invention includes a vertical movement module 10 in which a plurality of pieces are arranged in a grid form, And a motor driving module 20 that can individually control the height of the moving member 11 included in the vertical movement module 10 while moving along the respective rows.

In order to reduce the number of motors 21 used in the grid arrangement of the vertical movement module 10, the motor drive module 20 composed of a plurality of motors 21 moves along the transport rail 30 to be described later, Each of the moving members 11 of the module 10 can be individually driven. For example, in the case of the 7 × 7 arrangement (see FIG. 1), the seven motors 21 constitute one row of the motor drive module 20, and the motor drive module 20 moves in parallel, The height of each moving member 11 included in the vertical movement module 10 can be controlled.

The guide member 12 may be coupled to the moving member 11 so as to surround the guide member 12 and at least a guide groove 120 having an elliptical shape may be formed at the center of the guide member 12. As the guide groove 120 is formed in an elliptical shape, the movable member 11, which receives the rotational force of the motor 21, can be prevented from rotating and can be moved up and down.

For example, when the plurality of motors 21 constituting the motor drive module 20 are driven, the vertical movement height of the plurality of moving members 11 constituting the first row of the vertical movement module 10 is controlled individually And the height data of the moving members 11 moving at every moment can be recorded by an encoder (not shown) directly connected to the motors 21.

Further, there is an advantage that the torque of the motor 21 can be directly transmitted to the shifting member 11 so that it can be driven more effectively.

When the curved surface information is inputted from the PC 70, the curved surface information can be transmitted to the plurality of motors 21 constituting the motor driving module 20 through the motor control board 60. The motor drive module 20 can move in one direction along the conveying rail 30 and control the vertical movement height of each of the moving members 11 through all the row positions of the vertical movement module 10 . At this time, the initial positions of the moving members 11 can be set through the sensor 40, which will be described later, before driving the plurality of motors 21 constituting the motor drive module 20 at the respective positions.

As described above, at least one portion of the movable member 11 may be composed of a lead screw. At this time, a lead screw nut 110 may be further coupled to one side of the outer circumferential surface of the lead screw. The lead screw nut 110 can be rotated by receiving the driving force of the motor 21, so that the moving member 11 can be moved up and down by translational motion.

More specifically, in order to minimize the gap between the up-and-down movement modules 10 arranged in a grid form in the presentation of the three-dimensional curved surface, the lower end of the moving member 11, that is, the guide groove 120 formed in the guide member 12, When the lead screw portion is wrapped by the lead screw nut 110 and is rotated by receiving the rotational motion of the motor 21, the moving members 11 are rotated by the lead screw It is possible to perform translational motion in the vertical direction by the mechanism.

The motor drive module 20 includes a plurality of motors 21 that generate driving force and a plurality of motors 21 that are rotatable by a plurality of motors 21 and which are meshed with lead screw nuts 110, (22). Further, the motor support portion 210 for supporting the respective motors 21 may be further included. At this time, a motor control board 60 capable of transmitting arbitrary three-dimensional curved surface information to each of the plurality of motors 21 constituting the motor drive module 20 can be included (see FIG. 2).
