Abstract:In the production process of the crude foil machine, the ultra-thin copper foil is very easy to wrinkle. The roll surface must be wrapped with tape to eliminate wrinkling and stabilize production. The wrinkling of copper foil will result in a sharp drop in output and qualified rate of finished products, and bring about greater economic losses. In view of the common pain points in this industry, this paper analyzes the causes of copper foil wrinkling, and determines the main factor of equipment defects. By taking a series of transformation measures, the problem that the copper foil needs to be wrapped with adhesive tape is effectively solved, and the production requirements of ultra-thin copper foil are met, thus the finished products ratio of copper foil production is greatly improved with significant economic benefits.
