Wire connecting and slitting machine for large-sized pole piece of lithium-ion battery

Abstract

The invention discloses a wire connecting and slitting machine for a large-sized pole piece of a lithium-ion battery. The wire connecting and slitting machine for the large-sized pole piece of the lithium-ion battery comprises a frame and a positioning panel, wherein two sides of the positioning panel are provided with positioning power air cylinders, pushing-pressing plates for positioning the pole piece and adsorption components, so as to form clamping plate type positioning on the pole piece; the front side of the positioning panel is provided with a material pushing motor; the rear of the positioning panel is provided with a roll-cutting machine head; the lower part of the roll-cutting machine head is provided with a material discharge roller; a roll-cutting motor, the material pushing motor and the material discharge roller form push-pull material feeding; the pole piece of a battery is subjected to roll-cutting forming. The wire connecting and slitting machine can be connected with one plate painting machine or synchronously connected with two plate painting machines. The wire connecting and slitting machine for the large-sized pole piece of the lithium-ion battery is high in complete-machine degree of automation, works reliably and is high in efficiency; the whole machine can be moderately adjusted and replaced according to the size of the pole piece of the battery, is convenient to adjust, is high in applicability, and is applicable to the forming production of different pole pieces of the lithium-ion battery; the problems that a burr and the powder fall exist in the forming of the pole piece by a single-chip die-cutting machine are solved; waste materials in the forming process of the pole piece are reduced; the production cost is decreased; the production efficiency is improved.

Description

technical field [0001] The invention relates to a large-scale pole piece slitting machine for lithium ion batteries, and also relates to a processing method for forming battery pole pieces. Background technique [0002] In the production process of lithium-ion battery pole pieces, pole piece forming is one of the most critical processes. At present, there are generally two technological processes for the formation of lithium-ion battery pole pieces. One is to directly use a die-cutting machine to form one-time forming; The way to complete the forming of the overall pole piece. However, the second process is only suitable for small pole pieces. After forming the tabs, the pole pieces of lithium-ion batteries are usually about 100mm in length; while in the first process, the die-cutting machine can guarantee large-scale pole pieces. The completion of the sheet, but in order to ensure the integrity of the formed pole piece, there will be a 3-5mm gap between the die-cut pole p...
