Description

Technical Field

[0001] This utility model relates to the field of electrolytic copper foil processing technology, specifically to a low-energy-consumption electrolytic copper foil drying device. Background Technology

[0002] Copper foil is an important material in the manufacture of copper-clad laminates and printed circuit boards. Because copper foil is easily contaminated by grease, sweat, and other substances during transportation and storage, and because of its high surface activity, it is prone to forming an oxide layer, it must undergo degreasing and pickling before rough processing. After processing, the electrolytic copper foil needs to be dried, thus requiring a drying device. Most existing drying devices for electrolytic copper foil use hot air to dry it, which is inconvenient for automatically wiping and cleaning the foil before and after drying. Existing methods that only use hot air drying often result in water stains on the electrolytic copper foil after drying, requiring separate wiping and cleaning, leading to low efficiency and failing to meet usage requirements.
