New energy automobile single-layer lithium ion battery diaphragm manufacturing equipment and manufacturing process thereof

Abstract

The invention relates to new energy automobile single-layer lithium ion battery diaphragm manufacturing equipment and a manufacturing process thereof. The equipment comprises a preparation box body, afeeding hole, a feeding bin, a heating stirring rod, a rotating shaft, a mixing box, a motor, a transmission belt, a torsional spring, a transmission shaft, an annular frame, a half gear and a rack;the feeding bin is arranged on the left side of the top end surface of the preparation box; the feeding hole is formed in the left side of the top end surface of the mixing box; the rotating shaft isrotationally connected into the preparation box body; the heating stirring rod is arranged on the rotating shaft; the output end of the motor is fixedly connected with the rotating shaft; the annularframe is connected to the right end surface in the preparation box body through a spring; the output end of the motor is connected with the transmission shaft through the transmission belt; the rack is located in the annular frame; the half gear is installed on the transmission shaft; and the mixing box is fixedly connected with the annular frame. The purpose of intermittent discharging is achieved, mixing is made to be uniform as much as possible, and in the stirring process, the mixing box is made to move, the stirring effect is improved, stirring dead corners are eliminated, and the stirring efficiency is improved.

Description

technical field [0001] The invention relates to the field of manufacturing equipment for lithium-ion battery diaphragms, in particular to manufacturing equipment and a manufacturing process for single-layer lithium-ion battery diaphragms for new energy vehicles. Background technique [0002] Battery diaphragm refers to a layer of diaphragm material between the positive and negative electrodes of the battery. It is a very critical part of the battery and has a direct impact on battery safety and cost. Its main function is to isolate the positive and negative electrodes and make the electrons in the battery It cannot pass through freely, allowing the ions in the electrolyte to pass freely between the positive and negative electrodes. The ion conductivity of the battery separator is directly related to the overall performance of the battery. Its function of isolating the positive and negative electrodes enables the battery to limit the increase in current when the battery is ov...
