Pillar mounting method, method for manufacturing glass panel unit, and pillar mounting device
A pillar mounting method includes an accommodation step, a mounting step, and a displacement step. The accommodation step is a step of accommodating a plurality of pillars in storage with the plurality of pillars being stacked on each other. The mounting step is a step of pushing one pillar of the plurality of pillars accommodated in the storage out of the storage and mounting the one pillar on a substrate including a glass pane. The displacement step is a step of changing a relative location between the substrate and the storage. The mounting step and the displacement step are alternately repeated to mount the plurality of pillars in a predetermined arrangement on the substrate such that the plurality of pillars are apart from each other.
1. A pillar mounting method, comprising:
an accommodation step of accommodating a plurality of pillars in storage with the plurality of pillars being vertically stacked on each other;
a mounting step of pushing, out of the storage, one pillar of the plurality of pillars accommodated in the storage in a state where the plurality of pillars are vertically stacked on each other and mounting the one pillar on a substrate including a glass pane; and
a displacement step of changing a relative location between the substrate and the storage,
the mounting step and the displacement step being alternately repeated to mount the plurality of pillars in a predetermined arrangement on the substrate such that the plurality of pillars are apart from each other,
in the accommodation step, the plurality of pillars being accommodated in the storage with the plurality of pillars being pinched by a holding mechanism, and
in the mounting step, the one pillar of the plurality of pillars pinched by the holding mechanism being pushed out of the storage.
2. The pillar mounting method of claim 1 , wherein each of the plurality of pillars are aligned along a single axis.
3. A method for manufacturing a glass panel unit, comprising:
a first process of mounting a plurality of pillars on a first substrate including a first glass pane;
a second process of:
placing a second substrate including a second glass pane to face the first substrate with a seal material having a frame shape being provided between the second substrate and the first substrate and
hermetically bonding the first substrate and the second substrate to each other with the seal material; and
a third process of evacuating and sealing an internal space surrounded by the first substrate, the second substrate, and the seal material,
the first process including:
an accommodation step of accommodating the plurality of pillars in the storage with the plurality of pillars being vertically stacked on each other;
a mounting step of pushing, out of the storage, one pillar of the plurality of pillars accommodated in the storage in a state where the plurality of pillars are vertically stacked on each other and mounting the one pillar on the first substrate; and
a displacement step of changing a relative location between the first substrate and the storage,
in the first process, the mounting step and the displacement step being alternately repeated to mount the plurality of pillars in a predetermined arrangement on the first substrate such that the plurality of pillars are apart from each other,
in the accommodation step, the plurality of pillars being accommodated in the storage with the plurality of pillars being pinched by a holding mechanism, and
in the mounting step, the one pillar of the plurality of pillars pinched by the holding mechanism being pushed out of the storage.
4. The method for manufacturing a glass panel unit of claim 3 , wherein each of the plurality of pillars are aligned along a single axis.
