Problems solved by technology
[0005] The invention can solve the problem that the existing equipment cannot ensure that the insulating layer is in a tensioned state when the insulating layer is packaged for the lithium-ion battery, thereby reducing the tightness of the insulating layer of the lithium-ion battery and reducing the winding speed of the insulating layer of the lithium-ion battery. At the same time, the insulating layer cannot be packaged in a multi-station working mode, thereby reducing the efficiency of insulating layer packaging, and the insulating layer cannot be smoothed after winding, and the insulating layer after winding It is easy to have steam drums, which reduces the smoothness of lithium-ion batteries after winding

The invention relates to a lithium ion battery manufacturing process which comprises a bottom plate, winding devices and a collecting frame, the winding devices are uniformly mounted at the upper endof the bottom plate, the collecting frame is arranged below the winding devices, and the collecting frame is mounted on the bottom plate. According to the invention, the problems that the winding tightness of the insulating layer of the lithium ion battery is reduced, the winding firmness of the insulating layer of the lithium ion battery is reduced, the insulating layer cannot be packaged by adopting a multi-station working mode and the production efficiency is low when the insulating layer of the lithium ion battery is packaged by adopting the existing equipment, the insulation layer packaging efficiency is reduced, the insulation layer cannot be flattened after being wound, and the wound insulation layer is easy to have a steam pocket, so that the smoothness of the wound lithium ion battery is reduced, and other problems are solved.
Description
technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a lithium ion battery manufacturing process. Background technique [0002] Lithium-ion battery is a kind of secondary battery. It mainly relies on lithium ions to move between the positive and negative electrodes. Lithium-ion batteries were first developed by Sony Corporation of Japan in 1990. Lithium-ion batteries have high energy density and average output. High voltage, low self-discharge, no memory effect, excellent cycle performance, fast charging and discharging, long service life, toxic and harmful substances, etc. are widely used in electronic products, transportation, household appliances and other fields. [0003] At present, the existing equipment usually has the following deficiencies when packaging the insulating layer for lithium-ion batteries: 1. The existing equipment cannot ensure that the insulating layer is in a tensioned state when the insul...
