Solution Overview
Problem
Existing electrode sheet transporting apparatuses face challenges in accurately detecting and handling electrode sheets during the manufacturing process of secondary batteries, leading to inefficiencies and potential defects.
Innovation Solution
An electrode sheet transporting apparatus is designed with a lighting member to radiate light on the supply area, a sensing member to detect light reflection from the electrode sheet, and a control member to adjust the operation based on the detected information, ensuring precise handling and transport of electrode sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a lighting member and sensing member are added to detect electrode sheets, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The lighting member acts as an intermediary that emits light toward the electrode sheet, enabling the sensing member to detect the electrode sheet's presence and position through light reflection. This intermediary light source resolves the contradiction by providing a non-contact detection method that improves accuracy without requiring direct physical interaction or complex mechanical sensors.
2Adaptability or versatility
If the supply member transports electrode sheets in an intersecting direction, then handling flexibility is improved, but transportation coordination complexity increases
Solution Approach 1:
The supply member is designed to reciprocate in the second direction, creating dynamic motion that enables flexible handling of electrode sheets. This dynamic reciprocating motion allows the system to adapt to different transport requirements while maintaining coordinated operation with the first transporting conveyor, resolving the contradiction between flexibility and coordination complexity.
