Description

A glue preparation device for a lithium-ion battery soft pack winding machine

technical field

The utility model relates to the field of lithium-ion batteries, in particular to a glue preparation device for a lithium-ion battery soft pack winding machine.

Background technique

At present, the production method of lithium-ion battery cell rolls is to first wind the positive electrode sheet, negative electrode sheet, and separator through a winding machine, and then paste the termination tape through the gluing device to keep it from loosening after the winding is completed. The adhesive tapes of the gluing device all adopt the glue delivery method of the flat platform. The tape that is too wide does not match the arc of the upper rubber wheel, which leads to the failure of normal gluing. Therefore, only tapes with a width of less than 20mm can be pasted. The range is not wide. If you need to paste a tape with a width of more than 20mm, you need to re-install the rubber wheel, which is time-consuming, affects production efficiency, and cannot well meet actual production needs.
