Motor Laminated Core Adhesive Distribution for Fewer Spray Pipelines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing production apparatus for motor laminated cores requires numerous pipelines for adhesive spraying, leading to inefficient pipeline connection, difficult maintenance, and uneven adhesive distribution, resulting in low production efficiency and energy consumption due to auxiliary heat curing.
Innovation Solution
A production apparatus with an adhesive spraying device featuring a ring-shaped adhesive spraying plate and die plates with strategically positioned adhesive openings and diversion channels, allowing for controlled adhesive distribution and reduced pipeline connections, along with a lifting device for vertical movement, enables efficient adhesive application and core formation at normal temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple adhesive spraying openings are provided with separate pipelines, then adhesive can be sprayed to multiple positions, but pipeline connection becomes troublesome and assembly efficiency decreases
Solution Approach 1:
Multiple adhesive spraying openings are connected to a common adhesive supply chamber instead of having separate pipelines for each opening. The adhesive supply chamber distributes adhesive to multiple spray openings through internal channels, reducing the number of external pipeline connections from multiple separate pipelines to a single supply line.
Solution Approach 2:
The adhesive supply chamber serves multiple functions: it stores adhesive, distributes it to multiple spray openings through internal channels, and provides a centralized connection point for adhesive supply. This multi-functional component eliminates the need for separate pipelines for each spray opening.
2Ease of operation
If multiple pipelines are connected manually for adhesive spraying, then each adhesive opening can be controlled independently, but assembly time increases and production efficiency decreases
Solution Approach 1:
Multiple adhesive spray openings are integrated into a single adhesive supply system with internal distribution channels. This merging of multiple separate pipeline connections into one integrated system dramatically reduces assembly time while maintaining the ability to control adhesive flow to different openings.
3Manufacturing precision
If adhesive spraying control device is butt-jointed with each adhesive spraying opening, then precise adhesive application is possible, but maintenance and cleaning become difficult
Solution Approach 1:
Multiple adhesive spray openings are consolidated into a single adhesive supply chamber with internal distribution channels. This integration maintains precise adhesive application to each opening while allowing maintenance personnel to access and clean the system through a single centralized chamber rather than multiple separate connection points.
4Reliability
If auxiliary electromagnetic induction heating is used for adhesive curing, then adhesive bonding is achieved, but energy consumption increases and production time decreases
Solution Approach 1:
The patent replaces the electromagnetic induction heating system with a mechanical pressing system. The adhesive is applied and then cured through mechanical pressure and ambient temperature conditions, eliminating the need for high-energy electromagnetic heating while still achieving reliable adhesive bonding.
