Inspection Apparatus Positioning Unit for Target Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection apparatuses face issues with precise positioning of voluminous inspection targets due to varying descent speeds of regulation pins, potential deformation from adsorption cups, and complex structures that hinder efficient loading and unloading, leading to inaccurate and inefficient inspections.
Innovation Solution
The inspection apparatus employs a positioning unit with a contact surface and locating pins to stabilize the inspection target, along with a restraining unit to secure the edge, allowing for precise positioning and efficient loading/unloading through a simplified structure that supports the inspection target's lower surface and edge, enabling accurate and rapid positioning and handling of multiple targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple regulation pins are used to support the inspection target, then positioning stability is improved, but positioning precision deteriorates due to varying descent speeds causing partial raising of the inspection target
Solution Approach 1:
The patent merges the functions of multiple regulation pins into a single positioner that contacts the lower surface of the inspection target. This single positioner provides both stability and precision by eliminating the coordination issues between multiple pins, while the restraining unit separately provides edge support to prevent deformation.
Solution Approach 2:
The patent segments the positioning function into two independent components: a positioner that contacts the lower surface for stable positioning, and a restraining unit that contacts the edge for additional support. This segmentation allows each component to optimize its function without interfering with the other, achieving both stability and precision.
2Stability of the object's composition
If adsorption cups are used to support the lower surface of the inspection target, then positioning stability is improved, but manufacturing precision deteriorates due to partial deformation of the inspection target
Solution Approach 1:
The patent extracts the adsorption function from the positioning system and replaces it with a mechanical contact surface on the positioner. This eliminates the deformation caused by adsorption cups while maintaining stable support through direct mechanical contact at the lower surface and edge of the inspection target.
3Stability of the object's composition
If a complex positioning module with multiple components is used, then positioning stability is improved, but device complexity increases leading to intricate loading and unloading operations
Solution Approach 1:
The patent merges multiple positioning components into a simplified system with a single positioner and restraining unit. This reduction in component count maintains positioning stability while significantly simplifying the loading and unloading operations, making the overall device less complex and more efficient.
4Device complexity
If a simplified positioning structure is used, then device complexity is reduced, but positioning precision deteriorates
Solution Approach 1:
The patent applies local quality by concentrating the positioning function at specific critical locations: the lower surface contact point and the edge contact point. This localized approach with the positioner and restraining unit achieves high precision without requiring a complex overall structure, as the key positioning functions are focused at these specific locations.
