Cell high-speed lamination apparatus

Abstract

The invention relates to the technical field of pole piece lamination, particularly to a cell high-speed lamination apparatus. The cell high-speed lamination apparatus comprises a driving mechanism, a lamination table and a mounting plate, wherein the driving mechanism is mounted on the mounting plate; the cell high-speed lamination apparatus also comprises a diaphragm moving mechanism and a rotary lamination mechanism mounted on the mounting plate; the diaphragm moving mechanism comprises a movable guiding rail and a diaphragm traction assembly; the diaphragm traction assembly is glidingly mounted on the movable guiding rail; the rotary lamination mechanism comprises a first rotary lamination assembly and a second rotary lamination assembly; the first rotary lamination assembly and the second rotary lamination assembly are in driving connection with the driving mechanism separately; and the first rotary lamination assembly and the second rotary lamination assembly are arranged on the two sides of the lamination table. The cell high-speed lamination apparatus is creative in structure, and capable of realizing uninterruptible feeding between the first rotary lamination assembly and the second rotary lamination assembly, so that lamination time can be saved, and faster and more efficient lamination and a shorter lamination period can be realized; and the lamination table is kept motionless in the lamination process, so that the lamination stability and accuracy can be improved, and the pole pieces can be stacked in a tidier manner.

Description

technical field [0001] The invention relates to the technical field of pole piece lamination, in particular to a high-speed lamination device for electric cores. 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] In the manufacturing process of lithium batteries, a laminating machine is usually used to assemble the positive and negative electrodes and separators of lithium battery cells into Z-shaped laminations to make ba...

Problems solved by technology

[0004] On the one hand, the lamination table goes back and forth between the positive and negative poles, and the stroke is long, resulting in a long cycle, slow loading speed, and low work efficiency. On the other hand, the lamination table goes back and forth between the positive and negative electrodes, resulting in Poor stability, poor precision, poor lamination effect
