Title:
METHOD, DEVICE AND SYSTEM FOR PREPARING COMPOSITE METAL FOIL
Document Type and Number:
WIPO Patent Application WO/2023/131099
Kind Code:
A1
Abstract:
The present invention provides a method, device and system for preparing a composite metal foil. The device comprises: primary and secondary double-sided coating modules (10, 20) which are arranged spaced apart. The primary double-sided coating module (10) comprises: a first evaporation column (11) and a second evaporation column (12) which are arranged opposite to each other, and an unwinding roller (13), a first evaporation source (14), a first group of passing rollers (15), a second evaporation source (16) and a second group of passing rollers (17) which are sequentially arranged from bottom to top on opposite surfaces of the first evaporation column (11) and the second evaporation column (12). The secondary double-sided coating module (20) comprises: a third evaporation column (21), and a first group of cooling rollers (22), third evaporation source (23), second group of cooling rollers (24), fourth evaporation source (25) and winding roller (26) which are sequentially arranged from top to bottom on the third evaporation column (21). Two evaporation sources and companion roller systems are arranged from bottom to top on the opposite surfaces of the first and second evaporation columns (11, 12) so as to achieve primary double-sided coating, and two evaporation sources and corresponding roller systems are sequentially arranged from top to bottom on the third evaporation column so as to achieve secondary double-sided coating, thereby increasing the site utilization rate and thin film production efficiency.
