A hand-held cylindrical flexible packaging lithium-ion battery flat film tooling

Abstract

The invention discloses a hand-held cylindrical soft-packed lithium-ion battery flat film tooling, which includes a base, the base includes a first positioning plate and a support column vertically fixed on one side of the surface of the first positioning plate, and a positioning handle is fixed on the surface of the support column. The top surface of the positioning handle has a positioning thread groove; the surface of the first positioning plate is fixed with a power fixing mechanism, and a flat film cylinder is fixed on the power fixing mechanism. A return compression spring is installed at the center of the bottom of the barrel. The invention directly clamps the cylindrical lithium-ion battery between several flat film rollers, and at the same time provides power to the flat film cylinder to drive the flat film rollers to rotate so as to realize the rapid and uniform extrusion of the flat film rollers on the surface of the battery. The efficiency is high, and the surface of the battery is smoother due to the uniform extrusion force.

Description

technical field [0001] The invention belongs to the field of soft-package battery production, and relates to a hand-held cylindrical flexible-package lithium-ion battery flat-membrane tooling. Background technique [0002] The flatness of flexible packaging lithium-ion batteries is one of the important indicators of the product. In the production process, it is difficult to make a flat flexible packaging power battery, especially in the manufacture of large-area batteries. The main reason is that the thickness of the battery cell is relatively thin and has no hardness. Aluminum-plastic film is relatively soft and will deform after stretching and heat sealing. Batteries are also bent and deformed during process flow and handling. In order to manufacture relatively smooth flexible packaging batteries, flat pressing is often used. However, due to the wrinkles on the surface of the aluminum-plastic film and the elasticity of the battery cell, the flat-pressing method can only...

AI Technical Summary

Problems solved by technology

In order to manufacture relatively smooth flexible packaging batteries, flat pressing is often used. However, due to the wrinkles on the surface of the aluminum-plastic film and the elasticity of the battery cell, the flat-pressing method can only eliminate the unevenness of the battery surface, but cannot eliminate the unevenness on the surface of the aluminum-plastic film. Wrinkles, poor leveling effect

The existing flat film method is to manually roll the battery from the middle to both sides with a flat film roller. Not only is the efficiency low, but also the unstable control of the human force will cause different local forces during the rolling process and make the battery surface uneven. And when the battery is tested before production and packaging, when the battery with an uneven surface film needs to be collected uniformly and then laminated, and then packaged, it is not only inconvenient but also affects production efficiency
