A device and method for preparing ultra-thin rolled copper foil

Abstract

The invention relates to a copper foil preparation device and method, in particular to a preparation device and method for an ultra-thin rolled copper foil. The preparation device comprises a whole machine support, a rolling support, a power mechanism, a planetary mechanism, a transmission mechanism I, a transmission mechanism II, a transmission mechanism III, a rolling mechanism I, a rolling mechanism II, a transmission mechanism IV, a supporting mechanism I, a supporting mechanism II and an adjusting mechanism. A copper foil with the thickness being 0.3mm-0.4mm and extension Al being 1.3 isplaced between a rolling roller I and a rolling roller II for rolling, an adjusting handle is rotated to enable the relative long distance between the rolling roller I and the rolling roller II to bechanged, the copper foil is again placed between the rolling roller I and the rolling roller II for rolling, the thickness of the copper foil reaches 0.012-0.10 mm, and the rolling roller I and the rolling roller II are ground to flat rollers to realize comprehensive rolling of the copper foil. A supporting roller I is ground to a flat roller to realize the support for the rolling roller I by thesupporting roller I to prevent the rolling roller I from deformation caused by excessive stress.

Description

technical field [0001] The invention relates to a copper foil preparation device and method, more specifically to an ultra-thin rolled copper foil preparation device and method. Background technique [0002] Copper materials are widely used in various fields due to their excellent properties of high electrical conductivity and thermal conductivity. The rolled copper foil, because of its ultra-thin, high density, high flexibility, and more excellent performance, is unique among copper products and is more and more favored by various industries for finishing. Now it has been widely used in lithium-ion batteries. , electronic information technology, copper foil tape, copper clad laminate, transformer shielding, wire and cable and other fields. At present, there are two main methods of domestic production of rolled copper foil. One is a multi-roll mill, which can produce relatively thin copper foil such as thickness 0.009㎜, one is the four-roll mill, the traditional production ...

The rolled copper foil, because of its ultra-thin, high density, high flexibility, and more excellent performance, is unique among copper products and is more and more favored by various industries for finishing. Now it has been widely used in lithium-ion batteries. , electronic information technology, copper foil tape, copper clad laminate, transformer shielding, wire and cable and other fields. At present, there are two main methods of domestic production of rolled copper foil. One is a multi-roll mill, which can produce relatively thin copper foil such as thickness 0.009㎜, one is the four-roll mill, the traditional production method is that the backup roll is ground into a flat roll and the work roll is ground into a convex roll. The disadvantage of the four-roll mill is that it can only produce copper foil above 0.015㎜, and it cannot be used according to different applications. Copper foils of different thicknesses need to be calendered
