A rolling machine for producing pole pieces of aluminum shell lithium-ion batteries

Abstract

The invention provides a roller press for producing a pole piece of an aluminum shell lithium ion battery, and relates to the technical field of roller presses. The roller press comprises a bottom plate, support frames and a roller wheel group, wherein the support frames are respectively installed at two ends of the bottom plate; each support frame comprises a vertical rod and a cross rod; one ends of the vertical rods are installed on the bottom plate, and one ends of the cross rods are vertically and fixedly connected with the other ends of the vertical rods; the roller wheel group is installed in the opposite areas of the two cross rods; the roller wheel group comprises a big roller wheel and a small roller wheel, wherein the big roller wheel is rotatablely installed at the connecting parts of the cross rods and the vertical rods by using a mounting shaft which passes through two through holes, and the small roller wheel is rotatablely installed in horizontal regulation holes by using a mounting shaft; a cutting board is installed on each cross rod; connecting rods are fixedly connected with the vertical rods positioned under the big roller wheel; each connecting rod is connected with a scraper, and a sliding plate is installed at the back of each scraper. After the roller press is used, the technical effects of automatically shearing the pole piece and automatically scraping the pole piece are achieved.

Description

technical field [0001] The invention relates to the technical field of rolling machines, in particular to a rolling machine for producing pole pieces of aluminum shell lithium ion batteries. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries generally use materials containing lithium elements as electrodes, which are representatives of modern high-performance batteries. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Lithium-ion batteries are used...
