Laminated Iron Core Adhesive Dosing for Variable Lamina Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adhesive application methods for laminated iron cores fail to adjust adhesive agent application amounts based on the varying shapes of different iron core laminae, leading to insufficient or excessive bonding, which can cause separation or fracture under external forces and increase manufacturing costs.
Innovation Solution
An adhesive agent applying apparatus with multiple discharge ports and a control device that adjusts adhesive application based on iron core lamina type, synchronized with punching signals, and controlled by a control device to vary application amounts and supply rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive agent is applied evenly to each iron core lamina, then the application process is simple, but bonding strength becomes insufficient in some parts and excessive in other parts under external forces
Solution Approach 1:
The patent applies local quality by varying the adhesive agent application amount according to the specific type and shape of each iron core lamina. The control device adjusts discharge amounts for different laminae based on their individual characteristics, ensuring appropriate bonding strength at each location rather than uniform application throughout.
2Strength
If adhesive agent application amount is increased to prevent separation, then bonding strength improves, but manufacturing cost increases
Solution Approach 1:
The patent changes the parameter of adhesive agent application amount dynamically based on lamina type. The control device adjusts discharge parameters for different laminae, optimizing adhesive consumption while ensuring sufficient bonding strength where needed and reducing waste where less adhesive is required.
3Quantity of substance
If adhesive agent supply is suspended when changing lamina types, then adhesive is applied only where needed, but bonding may be insufficient in non-overlapping regions
Solution Approach 1:
The patent applies dynamics by making the adhesive agent supply continuous rather than suspended during lamina type changes. The control device dynamically adjusts discharge amounts based on real-time lamina type information, ensuring adhesive is always applied appropriately to each lamina regardless of type transitions, thereby maintaining bonding reliability while optimizing adhesive usage.

AI summary
An adhesive agent applying apparatus includes an adhesive agent discharge head formed with multiple discharge ports configured to respectively discharge an adhesive agent toward multiple adhesive agent application points set in a part of a sheet steel strip corresponding to each iron core lamina; and an adhesive agent application control device configured to control discharge of the adhesive agent from the multiple discharge ports of the adhesive agent discharge head, wherein the multiple adhesive agent application points are arranged in same positions on each iron core lamina as seen in a stacking direction of each iron core lamina regardless of the type of each iron core lamina, and the adhesive agent application control device controls the discharge of the adhesive agent from the multiple discharge ports so as to change an application amount of the adhesive agent to at least some of the multiple adhesive agent application points depending on the type of each iron core lamina.
