Optical Article Inspection With Indexed Batch Holder Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automated inspection devices for optical articles require manual loading and unloading of lenses, are time-consuming, and lack the capability for batch processing, leading to inefficiencies and inconsistent results.
Innovation Solution
An automated inspection apparatus with an indexable holding platform and gripper mechanism that allows for simultaneous loading and unloading of multiple optical articles, featuring a rotary magazine with magnetically secured holders and a scalloped sidewall design to minimize light and fluid interference, along with a temperature control system for consistent inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual loading and unloading of lenses is performed in conventional automated inspection devices, then the inspection process can be automated to eliminate manual inspection, but the processing time increases significantly and batch processing capability is lost
Solution Approach 1:
The inspection system is segmented into multiple independent inspection stations arranged in a batch processing configuration. Multiple lenses can be loaded simultaneously into the holding chamber, and the system processes them through divided inspection stages, allowing parallel processing that maintains high automation while improving productivity
Solution Approach 2:
Lenses are pre-loaded into holders and arranged in the holding chamber before the inspection process begins. This preliminary preparation allows the automated inspection to proceed without interruption, eliminating the time-consuming sequential loading that plagues conventional systems
2Measurement precision
If sequential inspection of individual lenses is performed, then each lens can be thoroughly inspected for defects, but the overall inspection time for multiple lenses becomes excessively long
Solution Approach 1:
Multiple inspection stations are merged into a single integrated batch processing system. The holding chamber accommodates multiple lenses simultaneously, and inspection functions are combined across parallel stations, enabling thorough defect detection for each lens while reducing total inspection time through concurrent processing
3Ease of manufacture
If the holding platform is stationary, then the structure is simple and easy to manufacture, but it cannot accommodate batch processing of multiple optical articles
Solution Approach 1:
The holding platform is transformed from a stationary structure to a rotatable mechanism that can index between multiple positions. This dynamic capability allows the platform to present different holders to inspection stations sequentially, enabling batch processing while maintaining relatively simple construction through the use of indexed rotational movement rather than complex continuous motion mechanisms
