Crown Centering Magnetic Gripper for Battery Cell Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing magnetic grippers for battery cells have a solid structure that complicates the gripping process and do not ensure safe handling, requiring precise alignment and movement of the battery towards the contact surface.
Innovation Solution
A magnetic gripper with a contact surface and a magnet, accompanied by centering elements arranged like a crown around the contact surface, allowing the battery cell to slide into position and be centered automatically, ensuring safe and reliable gripping with minimal design effort and space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a solid magnetic gripper structure is used, then the gripping force is sufficient, but the device complexity and installation space increase
Solution Approach 1:
The magnetic gripper is divided into a magnet unit and a separate support structure with centering elements. This segmentation allows the magnet to be compact while the support structure provides positioning functions, reducing overall device complexity and installation space while maintaining sufficient gripping force through the concentrated magnet design.
2Reliability
If precise alignment is required for the battery cell, then the gripping reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
Centering elements are provided that preliminarily position and center the battery cell before the magnetic gripping action occurs. These centering elements guide the battery cell into the correct position automatically, so that when the magnetic field is activated, the battery is already properly aligned, ensuring reliable gripping without requiring precise manual alignment operations.
3Reliability
If the battery cell is moved toward the contact surface, then the gripping is achieved, but the risk of unintentional displacement increases
Solution Approach 1:
The centering elements are arranged asymmetrically around the contact surface, creating a funnel-like guiding structure that naturally directs the battery cell toward the center position. This asymmetric arrangement ensures that during the approach movement, the battery cell is continuously guided and centered, reducing the risk of unintentional displacement while maintaining safe handling throughout the gripping process.
