Laser Marking Alignment Using Camera Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing marking technologies rely solely on manual positioning of objects based on visual cues, leading to human error and inconsistency, especially with complex shapes or precise orientations, which can result in aesthetic issues and incorrect engraving, particularly affecting barcode or QR code recognition.
Innovation Solution
A marking process and apparatus that separates manual positioning from visual analysis by using a camera and proprietary software to display the object's image on a screen, allowing real-time alignment and correction before marking, with features like image recognition algorithms and motorized movement for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning based on visual light guide is used, then the apparatus is simple and easy to operate, but positioning precision and consistency deteriorate due to human error
Solution Approach 1:
The patent replaces the manual visual positioning system with an automated image recognition and feedback system. A camera captures the object's position, processing means analyze the image to determine alignment with the light guide, and motorized means automatically adjust positioning based on the analysis, eliminating reliance on human visual judgment and manual adjustment.
Solution Approach 2:
The patent implements a closed-loop feedback system where the camera continuously monitors object position, the processing means compare actual position with desired position based on light guide alignment, and the system automatically adjusts positioning until alignment criteria are met, ensuring consistent precision without human error.
2Manufacturing precision
If automated image recognition and feedback system is implemented, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into existing components: the camera serves both as a positioning sensor and a verification tool, the processing means analyze both image data and light guide parameters, and the motorized means perform both positioning and alignment adjustments, reducing the need for separate dedicated components for each function.
Solution Approach 2:
The patent introduces a processing means as an intermediary that bridges the camera and the motorized positioning system. This intermediary analyzes image data, determines alignment status, and generates appropriate adjustment commands, simplifying the overall control architecture by centralizing the decision-making logic in a single processing unit.
