Wafer Sheet Supply Table Arc Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component supply devices for mounters require complex angle adjusting mechanisms to position wafer sheets at a predetermined angle, leading to increased device size and complexity.
Innovation Solution
A component supply device with a rotating table mechanism that uses arc-guided support points, allowing for precise angle adjustment without the need for guides across the entire circumference, thus simplifying the mechanism and reducing the number of actuators required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an angle adjusting mechanism is equipped on the table to adjust the wafer sheet angle, then the wafer sheet can be adjusted to a predetermined angle, but the mechanism becomes complex and the table becomes larger
Solution Approach 1:
The angle adjustment function is segmented from the main table body and integrated into the rotating mechanism. The table is divided into a fixed base and a rotatable section, with angle adjustment achieved through the rotating mechanism's segmented guide structure rather than a comprehensive angle adjusting mechanism across the entire table.
Solution Approach 2:
Instead of providing guides for the entire circumference of the table, guides are provided only for a portion of the circumference. The support points move along these partial guides in an arc fashion, which is sufficient to achieve the required angle adjustment without the complexity of complete circumferential guiding.
2Manufacturing precision
If an angle adjusting mechanism is equipped on the table to adjust the wafer sheet angle, then the wafer sheet can be adjusted to a predetermined angle, but the table size increases
Solution Approach 1:
The table structure is segmented into a compact fixed base and a rotatable section. The angle adjustment function is localized to the rotating mechanism rather than being distributed across the entire table surface, reducing the overall table footprint while maintaining adjustment capability.
Solution Approach 2:
Guides are implemented only for a portion of the circumference rather than the entire circumference. This partial guiding approach reduces the spatial requirements of the table while still enabling precise angle adjustment through arc movement of support points along the partial guides.

AI summary
A component supply device which includes a moving slider for moving between a position near a wafer sheet replenishment section and a position near a mounter, a table supported on the moving slider, and a rotating mechanism for rotating the table around a specific rotation axis. The table is supported on the moving slider by a number one support point, a number two support point, and a number three support point which are provided on a circumference with the rotation axis at the center. The rotating mechanism includes a number one guide for moving number one support point in an arc with respect to the rotation axis, and driven guides for moving number two support point and number three support point in an arc with respect to the rotation axis.
