Electrode Plate Laser Cutting with Vision-Based Misalignment Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrode manufacturing devices face issues with misalignment of electrode plates during processing using a laser beam due to unintentional movement during roll-to-roll transport.
Innovation Solution
An electrode manufacturing apparatus with a jig unit, laser cutting portion, and a controller that adjusts the fixing position of the jig unit and laser beam irradiation based on misalignment sensed by a vision portion, ensuring precise cutting of electrode plates into a set shape despite unintentional meandering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electrode plates are transported in a roll-to-roll manner, then productivity is improved, but manufacturing precision deteriorates due to misalignment
Solution Approach 1:
The vision portion detects the actual position of the electrode plate during transport and feeds back the misalignment information to the controller. The controller then adjusts the laser beam irradiation position or jig unit fixing position based on this feedback, enabling real-time compensation for misalignment and maintaining manufacturing precision while using roll-to-roll transport for high productivity
Solution Approach 2:
The system dynamically adjusts the fixing position of the jig unit and the irradiation position of the laser beam based on the detected misalignment. This dynamic adjustment allows the system to adapt to position changes during roll-to-roll transport, maintaining cutting precision despite the continuous movement and potential misalignment of the electrode plate
2Manufacturing precision
If the electrode plate is fixed to the jig unit, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The jig unit serves multiple functions: it supports the electrode plate during transport, provides a reference for vision detection, and enables precise positioning for laser cutting. By making the jig unit multi-functional, the system achieves high manufacturing precision without adding separate dedicated components for each function, thereby limiting the increase in device complexity
