Therefore, the arrangement nozzle 300 can be raised and lowered while the nozzle body 301 is maintained in the opening 33 . The bottom surface of the placement nozzle 300 forms a contact surface 304 in contact with the glass substrate.

The placement nozzle 300 may be raised and lowered along the opening 33 . Accordingly, in order for the pillar supply head to supply the pillars to the glass substrate, the pillar supply head 10 is arranged in a state where the contact surface 304 of the arrangement 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 arrangement nozzle 300 rises by the interval at which the pillar supply head 10 descends by contact with the glass substrate. While the contact surface 304 of the arrangement nozzle 300 is in contact with the glass substrate, it may be precisely aligned at the pillar arrangement position on the glass substrate.

In this case, 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 for supplying the pillars.

The arrangement nozzle 300 serves as a path through which the pillars move in the vertical direction, and at least the arrangement hole 320 is formed at the lower portion to be larger than the diameter of the pillar to allow the pillar to be laid down in the lateral direction. Since the arrangement hole 320 is formed to have a larger size than the state in which the pillar is lying in the lateral direction, it is allowed to move the pillar in a lying state, to lie down while moving, or to lay the pillar in a state in contact with the glass substrate.

The arrangement hole 320 is provided with a pillar introduction hole 325 into which the pillar discharged from the second discharge passage 220 is lowered and inserted therein.

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 to reduce the cross-sectional area in a funnel shape. The pillar introduction hole 325 has an upper opening 333 sized to allow a pillar that has fallen from the second discharge passage 220 to enter the introduction hole 322 without separation. The inclined side surface 327 of the pillar introduction hole 325 guides the entry of the pillar 322 into the discharge hole 320 , and when the pillar collides, it may guide rotation of the pillar to a lying state.

The pillar supplying apparatus according to the present invention includes a motion operation unit 400 that causes movement of the discharge nozzle 300 to prevent the pillar from being erected 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 causing the placement nozzle ( 300) is in contact with the glass substrate and swings. When the placement nozzle 300 swings, the contact surface 304 of the placement nozzle 300 slides on the glass substrate. When a 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 arrangement nozzle 300 is made in at least two intersecting directions. For example, it may include a movement in the front-rear direction (eg, the x-direction) and the movement in the left-right direction (eg, the y-direction). These movements need not be repeated several times, and it may be sufficient that one movement occurs in directions intersecting each other. However, it is not limited thereto.

The movement of the placement nozzle 300 prevents the pillars 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 under its own weight along the arrangement hole 320 or the second discharge passage 220 and the arrangement hole 320 of the arrangement nozzle 300, and is placed by the motion driving unit 400 It can be prevented from being erected by the movement of the nozzle 300 . ADVANTAGE OF THE INVENTION According to this invention, it can prevent more effectively from generation|occurrence|production of the arrangement|positioning defect arrange|positioned in the state of the pillar erected on a glass substrate.

Hereinafter, a pillar arrangement method by the pillar supply device for a vacuum window according to the present invention will be described.

The pillar supply head is aligned to the pillar alignment position on the glass substrate so that the pillar supply device for the vacuum window feeds and places the pillar in the alignment position 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 lower contact surface of the placement nozzle contacts the glass substrate. The pillar feed head descends toward the glass substrate so that the placement nozzle rises to a predetermined gap, and thus the discharge nozzle rises through the opening of the nozzle support.

The lower contact surface of the placement nozzle is maintained 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 aligning unit 120 , and move downward through the first discharge passage 210 in a standing state and aligned in a line.

The separation unit 240 separates the pillars discharged from the first discharge passage 210 one by one and delivers them to the second discharge passage 220 .

The pillar song jig 244 receives the pillar while 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 and the pillar receiving hole 245 coincide with each other, and the pillar in the pillar receiving hole 245 is introduced into the second discharge passage 220 .

Since the second discharge passage 220 is sized to allow the pillar to be laid down in the lateral direction, the pillar is allowed to lie down in the lateral direction while falling through the second discharge passage 220 .

The pillar is discharged through the outlet of the second discharge passage 220 , and the pillar is inserted into the arrangement hole 320 of the arrangement nozzle 300 . Since the arrangement hole 320 has a size that allows the pillar to be laid down in the lateral direction, the pillar is allowed to lie down in the lateral direction while rotating while falling through the discharge hole 320 .

The pillar supply head 10 and the arrangement nozzle 300 provided in the pillar supply head are moved by the motion operation unit 400 . The contact surface 304 moves on the glass substrate while sliding while the contact surface 304 is in contact with the glass substrate of the placement nozzle 300 .

However, the pillar is prevented from standing in the movement arrangement hole 320 of the arrangement nozzle 300 . That is, the pillar is arranged in a state lying on the glass substrate. The pillar that is not laid down while falling through the second discharge passage 220 and the discharge hole 320 is laid down due to collision due to the movement of the placement nozzle.

Therefore, according to 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 position of the glass substrate.

In the above, preferred embodiments of the present invention have been described, but the present invention is not limited to the description of the above-described embodiments, and as long as it does not depart from the description of the claims of the present invention, those of ordinary skill in the art to which the present invention pertains Various modifications made by persons should also be construed as being within the protection scope of the present invention.
