Die cutting and laminating integrated device

Abstract

The invention discloses a die cutting and laminating integrated device and relates to the technical field of battery production equipment. The device includes pole sheet die cutting mechanisms, pole sheet conveying mechanisms, positive electrode sheet feeding mechanisms, negative electrode sheet feeding mechanisms, diaphragm unwinding mechanisms and double-laminating-table mechanisms. The positiveelectrode sheet feeding mechanisms and the negative electrode sheet feeding mechanisms are disposed on two sides of the double-laminating-table mechanisms, and the pole sheet conveying mechanisms aredisposed between the pole sheet die cutting mechanisms and the positive electrode sheet feeding mechanisms and between the pole sheet die cutting mechanisms and the negative electrode sheet feeding mechanisms. The diaphragm unwinding mechanisms are above the double-laminating-table mechanisms which comprise rotating shafts, rotating arms, central rotating shafts, first laminating tables and second laminating tables. The problems of low degree of automation of equipment and low production efficiency in the prior art are solved, the continuous lamination operation can be achieved, and the lamination efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, and more specifically, the invention relates to an integrated die-cutting lamination 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. [0003] The cells of lithium-ion batteries are generally stacked, that is, they are stacked by positive plates, separators, and negative plates. Transfer the positive electrode and nega...
