Problems solved by technology

During the development of lithium-ion batteries, the base material of lithium-ion batteries is getting thinner and the battery capacity requirements are getting bigger and bigger. Therefore, the requirements for production are getting higher and higher. The traditional laser cleaning equipment is on the pole piece coating roller After pressing and slitting, only a single electrode piece can be cleaned at a time, and due to the material characteristics, only the negative electrode piece can be cleaned, while the positive electrode is made of aluminum foil, which is relatively brittle and has a low melting point. After laser cleaning, the base material is easily damaged, which seriously affects the quality of tab welding in the subsequent process, and the safety cannot be guaranteed at all.

Abstract

The embodiment of the invention provides a laser washing and wiping all-in-one machine and a pole piece production line, and relates to the technical field of pole piece production equipment. The laser washing and wiping all-in-one machine comprises an unwinding mechanism, a front laser optical system, a front brush mechanism and a front wiping mechanism, the front laser optical system comprises multiple front lasers, the front lasers are used for forming preliminary front groove positions in the front face of a pole piece, and the front brush mechanism is used for brushing the preliminary front groove positions to form middle-step front groove positions. The front wiping mechanism is used for wiping the middle-step front groove positions to form a front welding groove positions. The laser washing and wiping all-in-one machine can be used for conducting groove position washing on a wide pole piece which is not stripped, multiple front welding groove positions can be washed at a time, and a base material of the pole piece cannot be damaged.

Description

Technical field[0001]BACKGROUND OF THE INVENTION 1. Field of the Invention This invention, in particular, in particular, to a laser cleaning and wiping integrated machine and a pole production line.Background technique[0002]With the rapid development of modern economy and science and technology, the requirements for automation of lithium-ion battery manufacturing equipment are getting higher. During the development of the lithium-ion battery, the substrate of the lithium-ion battery is getting thinner, and the battery capacity is getting larger, so for production requirements, the conventional laser cleaning equipment is in a polar coating roller. After the discharging scaling, only the single pole piece can only be cleaned, and because the material characteristics can only be cleaned, the positive electrode is crystal, the material is crisp, the material is less, after the molten The laser cleaning substrate is easily injured, and the quality of the extreme ear welding of the posts...
