Description

An automatic double-sided laminating fixture Technical Field

[0001] This utility model belongs to the field of coating technology, specifically relating to an automatic double-sided coating tool. Background Technology

[0002] Benefiting from the rapid growth of new energy vehicles and energy storage, my country's lithium-ion battery copper foil market has expanded rapidly. Future demand for lithium-ion battery copper foil in my country is expected to continue to grow, with a compound annual growth rate of 35% from 2020 to 2025, reaching approximately 470,000 tons in 2025. my country's lithium-ion battery copper foil, especially for power batteries, is trending towards thinner and lighter designs. The market share of 6-micron copper foil increased from 14% in 2017 to 34% in 2020, while the share of 4.5-micron copper foil was 3% in 2020. The trend towards thinner and lighter lithium-ion battery copper foil is inevitable, presenting excellent market opportunities for ultra-thin and extra-thin lithium-ion battery copper foil. However, the extremely thin substrate is highly susceptible to breakage and scratches during the coating process. Therefore, the non-coated side of the ultra-thin PET substrate used for composite copper foil needs to be coated with a protective film to increase strength, while the coated side also needs to be coated with a scratch-resistant protective film (removed before coating). This necessitates a tooling system capable of simultaneous double-sided coating. Summary of the Invention
