Substrate Holding Hand Inclination Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional substrate conveying hands struggle to adjust the inclination of their blades to match the inclination of substrates within storage containers, especially when the substrates or containers are inclined, leading to difficulties in supporting substrates effectively.
Innovation Solution
A substrate holding hand equipped with an inclination adjusting mechanism, comprising a frame, a blade, a mounting member, and inclination adjusting pins, allows for the adjustment of the blade's inclination relative to the horizontal direction by rotating the mounting member about predetermined axes, enabling the blade to align with the substrate's inclination regardless of the storage container's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hand main bodies are provided parallel to a horizontal direction in a side view to correspond to substrates stored in a substrate storage container, then the structure is simple and easy to manufacture, but the inclination of the blade cannot be adjusted to match the inclination of substrates when they are inclined with respect to the horizontal direction
Solution Approach 1:
The mounting member is designed to be rotatable about a predetermined rotation axis, allowing the blade's inclination to be dynamically adjusted to match the substrate's inclination. This dynamic adjustment capability enables the system to adapt to different substrate orientations while maintaining a relatively simple overall structure.
Solution Approach 2:
The hand main body is divided into separate components: a frame, a blade, and a mounting member that connects them. This segmentation allows the mounting member to be independently rotated to adjust the blade's inclination, providing adaptability without requiring complete structural redesign.
2Reliability
If the substrates are stored in a substrate storage container with inclination, then the storage capacity is maintained, but the blade cannot effectively support the substrates due to mismatched inclination
Solution Approach 1:
The rotatable mounting member allows the blade inclination to be dynamically adjusted to match the substrate inclination caused by container tilt. This ensures reliable substrate support while maintaining ease of operation through a simple rotation mechanism that can be adjusted as needed.
3Ease of manufacture
If the blade is designed to support substrates horizontally, then the manufacturing is simple, but the blade bends due to its own weight and substrate weight causing inclination mismatch
Solution Approach 1:
Rather than attempting to manufacture a perfectly rigid blade that resists bending, the solution uses a rotatable mounting member that allows the blade inclination to be adjusted after assembly. This maintains manufacturing simplicity while achieving the required inclination precision through adjustment.
Solution Approach 2:
The system changes the inclination parameter of the blade by rotating the mounting member, rather than attempting to maintain a fixed horizontal inclination during manufacturing. This allows the blade to be manufactured simply while achieving precise inclination alignment through parameter adjustment.

AI summary
A substrate holding hand includes a frame, a blade to support a substrate, a mounting member to support the blade and mount the blade to the frame, and an inclination adjusting mechanism operable to adjust an inclination of the blade with respect to a horizontal direction in a side view by adjusting an inclination of the mounting member with respect to the frame.
