Adhesive Dispensing Control for Proactive Quality Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive dispensing technologies face challenges in maintaining consistent adhesive properties due to varying local and environmental parameters, leading to inefficiencies and waste, as manual adjustments are slow and imprecise, and automatic feedback loops are insufficient in preventing deviations before they affect production.
Innovation Solution
A method using a processor to optimize adhesive dispensing by obtaining target and local parameter values, generating a model of relationships between these parameters, and determining controllable settings for the dispensing device to maintain desired adhesive properties, allowing proactive adjustments and reducing waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment of dispensing parameters is used, then the system is simple to operate, but the adjustment speed and precision are insufficient leading to quality deviations
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated computer-controlled system that calculates optimal dispensing parameters based on detected adhesive properties and environmental conditions, thereby improving both precision and response time
Solution Approach 2:
The system implements a feedback loop where sensors continuously monitor adhesive properties (viscosity, temperature) and environmental parameters, and the controller automatically adjusts dispensing settings to maintain quality within specifications
2Manufacturing precision
If automatic feedback loop is implemented, then the response speed improves, but the system cannot prevent deviations before they occur leading to waste
Solution Approach 1:
The system performs preliminary adjustments by detecting changes in adhesive properties and environmental conditions before they cause quality deviations, proactively modifying dispensing parameters to prevent defects rather than reacting to them
Solution Approach 2:
The system dynamically adapts dispensing parameters in real-time based on continuous monitoring of adhesive viscosity, temperature, and environmental factors, allowing flexible adjustment to maintain optimal conditions throughout the dispensing process
3Manufacturing precision
If complex model-based optimization is implemented, then the dispensing precision and adaptability improve, but the device complexity increases
Solution Approach 1:
The patent introduces a computer as an intermediary that processes complex calculations and model-based optimization, separating the computational complexity from the physical dispensing mechanism and allowing precise control without complicating the hardware

AI summary
The invention provides a method and system for optimizing the dispensing of an adhesive from a dispensing device comprising a controllable setting. It consists in obtaining target parameters for a parameter of a structure formed by the adhesive after it is dispensed. Then a value of a local parameter near the dispensing device is obtained, which is a physical parameter of the adhesive in the dispensing device, an environmental condition near the dispensing device or a mechanical parameter of the dispensing device. Then a model of relationships between the local parameter, the parameter of the structure and intrinsic properties of the adhesive is generated. Using this model and the obtained values, a controllable setting for operating the dispensing device is determined to form a structure after dispensing of the adhesive that satisfies the target parameter.
