Along the jig moving passage 242, the first discharge passage 210 is disposed to be movable between a lower position and an upper position of the second discharge passage 220.

The pillar song jig 242 receives the erected pillar discharged from the first discharge passage 210 in the pillar receiving hole 245 in an erect state and moves toward the second discharge passage 220, and the second discharge passage 220. When the passage 220 and the pillar accommodating hole 245 coincide with each other, the pillar accommodated in the pillar accommodating hole 245 falls into the second discharge passage 210 by its own weight. The pillar is delivered to the second discharge passage 210 as it is in an upright state. At this time, the jet air supplied from the first blower 132 through the second jetting path 134 falls from the pillar receiving hole 245 of the pillar song jig 242 and moves to the second discharge passage 220. help to do

According to the embodiment of the present invention, the second discharge passage 220 is formed larger than the diameter of the pillar in a lying state, so that it can be rotated and laid horizontally while falling through the second discharge passage 220. . However, it is not limited thereto. Since the pillar can be laid down in the disposition hole 320 of the discharge nozzle 300, the second discharge passage 220 can be formed to a size capable of receiving the pillar receiving hole 245.

The actuator 246 is provided on one side of the pillar song jig 244, and the pillar song jig 244 reciprocates.

The lower body 30 is provided with a placement nozzle 300 on the lower side of the second discharge passage 220 to place the pillar in a lying state on the glass substrate.

The placement nozzle 300 is supported on the lower body 30 so as to be able to move up and down. In the lower body 30, a moving space 35 allowing the upward movement of the placement nozzle 300 is formed on the lower side of the second discharge passage 220, and the placement nozzle 300 is formed on the lower side of the movement space 23. ) is formed with a nozzle support portion 34 formed with an opening 33 into which is inserted.

The placement nozzle 300 includes a nozzle body 301 extending to the outside of the lower body 30 through the opening 33 and a nozzle head 302 having a larger diameter than the opening 33 at the top of the nozzle body 301. do. Accordingly, the placement nozzle 300 can move up and down while the nozzle body 301 is maintained in the opening 33 . The bottom surface of the placement nozzle 300 forms a contact surface 304 contacting the glass substrate.

The placement nozzle 300 may move up and down along the opening 33 . Therefore, in order for the pillar supply head to supply pillars to the glass substrate, the pillar supply head 10 is arranged in a state in which the contact surface 304 of the placement nozzle 300 is in contact with the glass substrate. The pillar supply head 10 descends by a predetermined interval with respect to the glass substrate, and accordingly, the placement nozzle 300 rises by the interval at which the pillar supply head 10 descends due to contact with the glass substrate. In a state where the contact surface 304 of the placement nozzle 300 is in contact with the glass substrate, it can be precisely aligned at the position of the pillar arrangement on the glass substrate.

At this time, since only a load corresponding to the weight of the placement nozzle 300 is applied to the glass substrate, it is possible to prevent damage to the glass substrate. That is, it is possible to prevent damage to the glass substrate when the pillar supply head is aligned with the glass substrate to supply the pillar.

The placement nozzle 300 serves as a path through which the pillars move in the vertical direction, and has a placement hole 320 that is larger than the diameter of the pillars and allows the pillars to be laid down in the horizontal direction at least at the bottom. Since the placement hole 320 is formed in a size larger than that of the pillar lying horizontally, it allows the pillar to move in a lying state, lie down while moving, or lie down while in contact with the glass substrate.

The arrangement hole 320 has a pillar introduction hole 325 at the top of which the pillar discharged from the second discharge passage 220 descends and is inserted.

According to the embodiment of the present invention, the pillar introduction hole 325 has an enlarged top opening 326 and has an inclined side surface 327 so that the cross-sectional area is reduced in a funnel shape. The pillar introduction hole 325 has an upper end opening 333 of a size through which the pillar that has fallen from the second discharge passage 220 can enter the introduction hole 322 without being separated. The inclined side surface 327 of the pillar introduction hole 325 may guide the entry of the pillar 322 into the discharge hole 320, and may guide the rotation of the pillar to lie down when the pillar collides.

The pillar supply device according to the present invention includes a motion operation unit 400 that causes the discharge nozzle 300 to move so that the pillar is prevented from standing in the discharge hole 320 of the discharge nozzle 300 .

According to the embodiment of the present invention, the motion operation unit 400 causes the pillar supply head 10 to move while the lower contact surface 304 of the discharge nozzle 300 is in contact with the glass substrate, thereby disposing the placement nozzle ( 300) performs an oscillating motion while in contact with the glass substrate. When the placement nozzle 300 vibrates, the contact surface 304 of the placement nozzle 300 slides on the glass substrate. When force is applied to the placement nozzle 300, the placement nozzle 300 rises along the opening 33 so that the movement of the placement nozzle 300 does not damage the glass substrate.

It is advantageous that the direction of movement of the placement nozzle 300 is formed in at least two intersecting directions. For example, it may include movement in a forward-backward direction (eg, x direction) and movement in a left-right direction (eg, y-direction). These movements do not need to be repeated several times, and it may be sufficient for one movement to occur in a direction that crosses each other. However, it is not limited thereto.

The movement of the placement nozzle 300 prevents the pillar from being erected inside the placement hole 320 . The pillar is induced to lie down while colliding with the inner surface of the arrangement hole 320 .

The pillar can be laid down by the movement of falling by its own weight along the placement hole 320 of the placement nozzle 300 or the second discharge passage 220 and placement hole 320, and the placement by the motion drive unit 400 It can be prevented from standing up by the movement of the nozzle 300 . According to the present invention, it is possible to more effectively prevent the occurrence of misalignment in which the pillars are disposed on the glass substrate in an upright state.

Hereinafter, a method for arranging pillars using a pillar supply device for a vacuum window according to the present invention will be described.

In order for the pillar supplying device for the vacuum window to supply and place the pillars at the alignment positions on the glass substrate, the pillar supply head is aligned at the pillar alignment positions on the glass substrate.

On the pillar alignment position of the glass substrate, the pillar supply head moves downward toward the glass substrate, and the bottom contact surface of the placement nozzle contacts the glass substrate. The pillar supply head descends toward the glass substrate so that the placement nozzle rises to a predetermined gap, and accordingly the discharge nozzle rises through the opening of the nozzle support.

The bottom contact surface of the placement nozzle remains in contact with the pillar alignment position on the glass substrate.

Meanwhile, the pillars accommodated in the pillar storage unit 100 are aligned in an upright state in the pillar arranging unit 120 and move downward through the first discharge passage 210 aligned in an upright state.

The separator 240 separates the pillars discharged from the first discharge passage 210 one by one and transfers them to the second discharge passage 220 .

The pillar song jig 244 receives the pillar in a state in which the pillar receiving hole 245 coincides with the first discharge passage 210 . The pillar song jig 244 moves horizontally so that the second discharge passage 220 and the pillar receiving hole 245 coincide.

The second discharge passage 220 coincides with the pillar receiving hole 245, and the pillar in the pillar receiving hole 245 is introduced into the second discharge passage 220.

Since the second discharge passage 220 is formed to a size that allows the pillar to lie down in the lateral direction, the pillar is allowed to lie down in the lateral direction of rotation while falling through the second discharge passage 220 .

The pillars are discharged through the outlet of the second discharge passage 220, and the pillars fall into the arrangement hole 320 of the arrangement nozzle 300 and are inserted. Since the placement hole 320 is formed in a size that allows the pillar to lie down in the lateral direction, the pillar is allowed to lie down in the lateral direction of rotation while falling through the discharge hole 320 .

The pillar supply head 10 and the placement nozzle 300 provided in the pillar supply head are induced to move by the motion actuator 400 . When the placement nozzle 300 is in contact with the glass substrate, the contact surface 304 slides and moves on the glass substrate.

However, the pillars are prevented from standing in the moving arrangement hole 320 of the placement nozzle 300 . That is, the pillars are placed on the glass substrate in a laid-down state. Pillars falling through the second discharge passage 220 and the discharge hole 320 but not laid down are laid down due to collision caused by the movement of the placement nozzle.

Therefore, with the pillar supply device for a vacuum window according to the present invention, it is possible to reliably ensure that the pillars are arranged in a lying state at the pillar alignment positions of the glass substrate.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the description of the above embodiments, and those skilled in the art in the art to which the present invention pertains unless departing from the description of the claims of the present invention Various modifications made by the person should also be construed as falling within the protection scope of the present invention.
