Multi-Outlet Glue Nozzle for Adhesive Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive nozzles face challenges such as excessive adhesive usage, leakage, and variable bonding quality due to inconsistent adhesive application, particularly when dealing with glass panes of different thicknesses, leading to suboptimal bonding and potential adhesive failure.
Innovation Solution
The adhesive nozzle features multiple outlet channels with varying cross-sections, allowing for controlled adhesive flow and compression within the adhesive gap, ensuring better adhesion by adjusting the discharge width and penetration depth, and reducing the overall adhesive amount required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single outlet nozzle is used to fill the adhesive gap, then the adhesive can be applied to the gap, but excessive adhesive is used and leakage occurs
Solution Approach 1:
The adhesive nozzle is divided into multiple outlet channels (first outlet channel with first outlet opening and second outlet channel with second outlet opening) that discharge adhesive at different positions and in different amounts. This segmentation allows precise control over adhesive distribution, preventing both over-application and under-application, thereby resolving the contradiction between adhesive quantity control and bonding reliability.
2Reliability
If adhesive is deflected to emerge counter to nozzle movement direction, then adhesive compression is improved, but large amount of adhesive is used
Solution Approach 1:
Instead of deflecting a large amount of adhesive in a single stream, the nozzle segments adhesive discharge into multiple channels with different flow rates. The first outlet channel provides higher flow rate for initial coverage while the second outlet channel provides lower flow rate for precise compression, achieving adequate compression with reduced total adhesive consumption.
Solution Approach 2:
Different outlet channels are designed with different cross-sectional areas to provide locally optimized adhesive flow characteristics. The first outlet opening has larger cross-section for high-flow compression needs, while the second outlet opening has smaller cross-section for precision application, allowing compression to be achieved with appropriate adhesive quantity distributed to different locations.
3Adaptability or versatility
If glass panes of different thicknesses are used, then application versatility is improved, but bonding quality becomes inconsistent
Solution Approach 1:
The multi-channel outlet design allows the adhesive to be distributed across different zones and depths, adapting to various glass thicknesses. By adjusting which outlets are active and their flow rates, the system maintains consistent bonding quality across different pane thicknesses, resolving the contradiction between versatility and bonding reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the bonding quality by achieving deeper penetration and compression of adhesive material, reducing waste and improving the adhesion process, making it suitable for various glass thicknesses and applications beyond glass pane bonding.
Implementation Method 1
At least one of the outlet openings (3, 4) has a smaller cross section than at least one other outlet opening. The adhesive material (50) exiting through the at least one outlet opening (3, 4) with the smaller cross section has a higher flow rate
Implementation Method 2
the adhesive material that has emerged via the outlet opening (3, 4) meets an adhesive material that has already emerged via another outlet opening (3, 4). As a result of the meeting of the two leaked adhesive materials in the adhesive gap (13), this is compressed there
