Abstract

The invention discloses an online slitting and winding device for a wet-process diaphragm of the lithium battery. On-line separation of the diaphragm can be realized as a small volume, and the production plan can be flexibly adjusted flexibly. The online slitting and winding device for a wet-process diaphragm of the lithium battery comprises a slitting mechanism and at least two winding mechanisms; the slitting mechanism comprises a rolling roller which is sequentially arranged along a membrane penetrating path of the diaphragm, a first guide roller, a second guide roller and a slitting roller, wherein the slitting roller is provided with a cutter; and each winding mechanism comprises a driven fog surface roller which is sequentially arranged along a membrane penetrating path of the separated diaphragm, a first driven mirror roller, a driving roller, a second driven mirror roller, a floating roller, a guide roller and a winding roller.

Description

technical field [0001] The invention belongs to the field of manufacturing lithium battery wet-process diaphragms, and in particular relates to an online cutting and winding device for lithium battery wet-process diaphragms. Background technique [0002] In the manufacture of wet separators for lithium batteries, winding is usually the last process, the purpose is to roll up the separators after trimming for easy storage and transportation. Traditional winding equipment is full-width winding (2-3m), which cannot flexibly respond to production plan adjustments, especially for ceramic diaphragms, which cannot be directly coated on large rolls. The slitting equipment is bulky, the equipment investment is high, and the adjustment ability is limited. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide an online slitting and winding equipment for lithium battery wet separators, which can cut the separators into sm...
