Electrode Transfer Suction Segmentation for Defect Unloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The issue of electrodes detaching from a belt due to insufficient suction force when suction holes holding defective electrodes are opened, leading to potential detachment during the transfer process in secondary battery production.
Innovation Solution
A secondary battery electrode production system with a transfer portion divided into areas for unloading and loading, featuring a suction driving portion, suction plate, and suction blocks with aligned flow paths and holes, allowing independent control of suction units to maintain suction status even when defective electrodes are unloaded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If suction holes holding defective electrodes are opened to separate defective electrodes from the belt, then defective electrodes can be removed, but suction force on the belt is reduced causing electrodes to detach
Solution Approach 1:
The suction plate is divided into multiple independent suction units, each with its own suction holes. This segmentation allows selective activation and deactivation of individual suction units, enabling defective electrodes to be released while adjacent electrodes remain held by other suction units that maintain their suction force.
Solution Approach 2:
Different regions of the suction plate have different suction states - some suction units are activated to hold good electrodes while other suction units are deactivated to release defective electrodes. This local differentiation allows simultaneous holding and releasing operations in different areas of the same belt.
2Reliability
If suction is switched off and back on quickly to maintain electrode holding, then electrode detachment can be prevented, but the rapid switching causes electrodes to fall from the belt before suction is restored
Solution Approach 1:
Adjacent suction units are pre-positioned and ready to activate before defective electrodes are released. When a defective electrode needs to be dropped, the neighboring suction units are already in place and can immediately take over holding function, eliminating the need for rapid suction switching and preventing electrode drops during the transition.
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
Prevents electrodes from detaching from the belt by maintaining suction force on adjacent electrodes, ensuring stable transfer and separation of defective electrodes without affecting the suction status of other electrodes.
Implementation Method 1
Electrodes with tabs formed are held in place on the belt by suction and transferred toward the magazine
