Jelly Roll Pairing Alignment to Prevent Battery Tab Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integrity of battery tabs is compromised during the production process due to interference and contact between jelly rolls, affecting charge and discharge performance.
Innovation Solution
A pairing device with a misalignment pairing apparatus that positions and rotates workpieces to achieve a prescribed orientation, minimizing interference and contact between jelly rolls, using independent linear and rotary drive mechanisms to facilitate precise alignment without mechanical gripping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pairing methods are used to pair jelly rolls, then the pairing process can be completed, but the tabs of the jelly rolls are damaged due to contact and interference between workpieces
Solution Approach 1:
The patent introduces a vertical dimension (height direction) to the pairing process by using a misalignment pairing apparatus that positions workpieces at different heights. The first workpiece is placed on a first pairing platform and the second workpiece is placed on a second pairing platform, with the second platform positioned higher than the first. This vertical separation prevents horizontal contact between workpieces during rotation, eliminating tab damage while maintaining pairing functionality.
2Productivity
If workpieces are positioned closely together for pairing, then pairing efficiency is improved, but the likelihood of contact and interference between workpieces increases
Solution Approach 1:
The patent resolves this contradiction by transitioning from horizontal proximity to vertical stacking. Workpieces are positioned at different heights on separate pairing platforms, allowing them to be closely positioned in the horizontal plane for efficient pairing while maintaining vertical separation that prevents interference. The misalignment pairing apparatus controls the vertical distance between platforms to optimize both efficiency and safety.
3Manufacturing precision
If mechanical gripping is used to hold and move workpieces, then positioning precision is improved, but the risk of tab damage from gripping forces increases
Solution Approach 1:
The patent replaces mechanical gripping with a non-contact positioning system. The misalignment pairing apparatus uses platform positioning mechanisms to hold and move workpieces without physical contact. Workpieces are placed on pairing platforms that can be precisely positioned and rotated, eliminating the need for mechanical grippers that could damage tabs while maintaining positioning precision through controlled platform movement.

AI summary
The pairing device includes a first positioning mechanism having a first pairing platform for placing the first workpiece; and a second positioning mechanism having a second pairing platform for placing the second workpiece. The first positioning mechanism and the second positioning mechanism are configured to enable at least one of the first pairing platform and the second pairing platform to move along a first direction, and enable at least one of the first pairing platform and the second pairing platform to rotate around the first direction. The first workpiece and the second workpiece are enabled to have a prescribed orientation by positioning the first pairing platform and the second pairing platform at staggered positions along the first direction, and rotating at least one of the first pairing platform and the second pairing platform around the first direction.
