AI Technical Summary
Existing lithium-ion battery separator tensile strength testing equipment suffers from severe clamping damage, low testing efficiency, and poor equipment adaptability, making it difficult to meet mass production requirements.
The fully automated tensile strength testing device uses negative pressure adsorption to carry and transfer the test strip. Combined with a sealed environment chamber, a strip preparation module, a tensile testing mechanism, and a visual strain acquisition component, it realizes a fully automated process from diaphragm unwinding to tensile testing, adapting to different testing standards and diaphragm types.
It significantly reduces clamping damage, improves detection efficiency and consistency, can meet the mass production needs of hundreds of millions of square meters, is compatible with multiple detection standards, and shortens the single detection cycle.
