Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mounting pillars on substrates in glass panel units are time-consuming when dealing with a large number of pillars, as they require individual suction and placement, which slows down the manufacturing process.
Innovation Solution
A pillar mounting method involving an accommodation step, a mounting step, and a displacement step, where pillars are alternately pushed out of storage and positioned on a substrate, allowing for efficient arrangement and spacing, utilizing a pusher and displacement mechanism to efficiently mount multiple pillars on a substrate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pillars are mounted one by one using suction pad, then each pillar can be precisely placed on the substrate, but the mounting process takes a long time when the number of pillars is large
Solution Approach 1:
The mounting process is segmented into two distinct phases: a batch accommodation phase where multiple pillars are loaded into storage simultaneously, and a sequential mounting phase where pillars are pushed out one by one to precise locations. This segmentation allows the system to combine the efficiency of batch processing with the precision of individual placement.
Solution Approach 2:
Pillars are preliminarily accommodated in storage in a stacked state before the actual mounting process begins. This preliminary action prepares multiple pillars in advance, so that during the mounting phase, they can be sequentially pushed out and placed without requiring individual suction and handling operations.
2Productivity
If multiple pillars are mounted simultaneously, then mounting speed increases, but it becomes difficult to maintain precise placement and proper spacing
Solution Approach 1:
Storage acts as an intermediary device between the pillar supply source and the substrate. It temporarily holds multiple pillars in a stacked configuration, allowing them to be sequentially accessed and placed one by one on the substrate. This intermediary structure enables both efficient batch handling and precise individual placement.
3Volume of stationary object
If pillars are stacked in storage, then space efficiency is improved, but access to individual pillars for mounting becomes more complex
Solution Approach 1:
The mounting mechanism extracts pillars from the stacked configuration in storage one at a time through a pushing action. This extraction method is simpler than individual suction operations, as it uses a single pushing motion to sequentially access and place each pillar, reducing the complexity of the access mechanism while maintaining space efficiency.

AI summary
A pillar mounting method, a method for manufacturing a glass panel unit, and a pillar mounting device which enable a plurality of pillars to be efficiently mounted on a substrate are provided. 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 (4) in storage (5) with the plurality of pillars (4) being stacked on each other. The mounting step is a step of pushing one pillar (4) of the plurality of pillars (4) accommodated in the storage (5) out of the storage (5) and mounting the one pillar (4) on a substrate (1) including a glass pane (100). The displacement step is a step of changing a relative location between the substrate (1) and the storage (5). The mounting step and the displacement step are alternately repeated to mount the plurality of pillars (4) in a predetermined arrangement on the substrate (1) such that the plurality of pillars (4) are apart from each other.
