High-speed multi-section pole piece manufacturing equipment

Abstract

The invention relates to the technical field of electronic element processing equipment and in particular to high-speed multi-section pole piece manufacturing equipment. The high-speed multi-section pole piece manufacturing equipment comprises a rack, and also comprises a material discharging apparatus, a material discharging caching apparatus, a pole piece punching apparatus, a draft gear, a material collecting caching apparatus and a material collecting apparatus that are arranged along a material conveying direction in sequence. The pole piece strip is cached by the material discharging caching apparatus and the pole piece punching apparatus, so that the draft gear is high in material pulling speed so as to realize the high speed punching on the pole piece strip by the pole piece punching apparatus; meanwhile, the feed amount of the required pole piece strip for punching in each time is unequal, the draft gear can rapidly pull the cached material according to punching needs; the draft gear is high in response speed, so that the high-speed multi-section punching and pole piece manufacturing is realized, and the production efficiency is greatly improved; and the material discharging apparatus and the material collecting apparatus perform uninterrupted pole piece strip collection at a constant speed to enable the pole piece strip to be kept at constant tensile force so as to improve the material conveying precision and to effectively prevent the phenomenon of off tracking of the pole piece strip and the like.

Description

technical field [0001] The invention relates to the technical field of electronic component processing equipment, in particular to a high-speed multi-stage film-making equipment. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Because of the above-mentioned characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, notebook computers, video cameras, and digital cameras.
