Eyeglass Lens Processing System Automating Re-grinding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyeglass lens processing systems require manual intervention for re-grinding, leading to inefficiencies and reduced productivity, as operators need to determine and input correction data for each lens, even when special processing is required.
Innovation Solution
An eyeglass lens processing system with multiple processing devices and a terminal that allows for the storage and transmission of processing information, enabling correction data to be set and applied automatically, allowing for efficient re-processing without continuous human attendance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual intervention is used for re-grinding, then correction data can be input and processed, but productivity decreases due to continuous human attendance requirement
Solution Approach 1:
The processing device automatically determines correction data by comparing frame shape data with lens shape data, and autonomously inputs corrected processing data without requiring operator intervention. The system serves itself by automatically detecting assembly issues and correcting processing parameters.
Solution Approach 2:
The system obtains assembly result information from the assembly step and feeds it back to the processing device. This feedback loop enables the processing device to automatically adjust correction data based on actual assembly outcomes, improving both precision and productivity.
2Manufacturing precision
If special processing is performed with simulation, then processing accuracy can be improved, but productivity decreases due to manual attendance requirement
Solution Approach 1:
The processing device automatically performs simulation based on obtained shape data and determination rules, and autonomously determines correction data without operator intervention. The system independently completes the entire special processing workflow.
Solution Approach 2:
The system performs simulation and determination of correction data before the actual re-grinding process. This preliminary action ensures processing accuracy is established in advance, allowing automated execution during the actual processing step.
3Reliability
If re-grinding is performed after assembly, then lens-frame compatibility can be improved, but time is lost due to manual determination and data input
Solution Approach 1:
The processing device automatically determines which parts need re-grinding by comparing frame and lens shape data, and autonomously inputs corrected processing data. This eliminates the time required for manual determination and data entry.
Solution Approach 2:
The manual mechanical process of operator determination and data input is replaced by an automated information processing system that electronically compares shape data and generates correction data, significantly reducing re-processing time.
