RFID-Guided Robot Removal Head Positioning for Chemical Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing removal systems for filling and draining liquid chemicals from containers require significant personnel effort and are prone to human exposure risks, while automated solutions using image processing systems are time-consuming and costly, and susceptible to interference.
Innovation Solution
A removal system utilizing an RFID chip on the container and a robot-mounted RFID reader unit for automated attachment and detachment of removal heads, enabling efficient and interference-resistant positioning and identification of container openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual attachment and release of removal heads is used, then personnel outlay is high and human exposure risk increases, but system complexity remains low
Solution Approach 1:
The patent replaces manual mechanical operations with an automated robot system equipped with a measurement head and RFID reader. The robot autonomously navigates to containers, reads RFID tags to identify container openings, and attaches removal heads automatically, eliminating the need for manual labor while managing system complexity through integrated automation components.
2Productivity
If image processing systems are used for localization, then automated mounting is achieved, but computing power requirements increase and operation time is extended
Solution Approach 1:
The patent substitutes image processing systems with RFID-based localization. Instead of using cameras and complex image evaluation algorithms that require significant computing power and time, the system uses RFID readers to quickly read tags on containers and determine container opening positions, dramatically reducing processing time and computational requirements while maintaining automation.
3Reliability
If image processing systems are used for localization, then automated mounting is achieved, but susceptibility to disruptive influences increases
Solution Approach 1:
The patent replaces optical image processing with RFID-based detection. RFID technology uses electromagnetic fields to communicate with tags on containers, making it immune to extraneous radiation, dust, and contamination that disrupt optical systems. This substitution significantly improves localization reliability in harsh industrial environments while eliminating susceptibility to harmful environmental factors.
