Laser Cutting Guide Notch for Stable Strip Electrode Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Strip electrodes rattle during laser cutting, causing the focal point of the laser beam to shift and making it difficult to achieve high precision in cutting.
Innovation Solution
A laser processing device with a conveyance system, a laser irradiating unit, and a guide with a notch that follows the predetermined path of the laser beam, effectively suppressing rattling by holding the strip electrode and maintaining the laser beam's focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the strip electrode is cut using a laser beam without suppression of rattling, then the cutting process can be performed, but the focal point of the laser beam shifts due to rattling, making it difficult to achieve high precision cutting
Solution Approach 1:
The guide with a notch is prepared in advance to match the predetermined path of the laser beam. The notch is designed to follow the laser beam's trajectory, allowing the strip electrode to be held stably before cutting begins. This preliminary preparation of the guide structure prevents rattling during the cutting process, ensuring the focal point remains on the strip electrode and high precision cutting is achieved.
2Manufacturing precision
If a guide with a notch following the laser beam path is used to suppress rattling, then cutting precision is improved, but the device complexity increases
Solution Approach 1:
Instead of adding complex suppression mechanisms throughout the entire cutting system, the invention applies a localized solution: a guide with a notch specifically positioned where the strip electrode contacts the guide during cutting. The notch is designed to match only the critical portions of the laser beam path, providing rattling suppression exactly where needed without unnecessary additional components, thus minimizing device complexity while maintaining high precision.
