Substrate Holding Hand Sensor Positioning Across Multiple Blades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing substrate conveying robots require a large number of work processes to position multiple substrate detection sensors correctly, which complicates the positioning task and reduces workability.
Innovation Solution
A substrate holding hand with a sensor support member and positioner that collectively positions multiple substrate detection sensors with respect to the blades, reducing the number of work processes needed for sensor positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple substrate detection sensors are provided to correspond to multiple blades, then the detection capability is improved, but the number of work processes to position the sensors increases
Solution Approach 1:
Multiple substrate detection sensors are merged into a single sensor support member, allowing them to be positioned collectively relative to multiple blades through one positioning operation rather than individually positioning each sensor
Solution Approach 2:
The sensor support member serves as a universal positioning structure that simultaneously supports and positions multiple substrate detection sensors relative to multiple blades, making the positioning system multi-functional
2Manufacturing precision
If multiple substrate detection sensors are positioned individually with respect to multiple blades, then each sensor can be accurately positioned, but the positioning time increases
Solution Approach 1:
The positioning operations for multiple sensors are merged into a single collective positioning action through the sensor support member, maintaining accuracy while reducing the time required
Solution Approach 2:
The sensor support member is designed in advance with predetermined positions for multiple sensors, allowing them to be collectively positioned in one operation rather than requiring sequential individual positioning
