Method for rapidly testing quality of aluminum foil incoming material of aluminum-plastic film

Abstract

The invention discloses a method for rapidly testing the quality of an aluminum foil incoming material of an aluminum-plastic film. The method comprises the following steps: testing preparation is made: an aluminum foil roll material is rotatably placed on a goods shelf, a reference roller is arranged on one side of the aluminum foil roll material, the axis of the aluminum foil roll material is kept parallel to the axis of the reference roller, and the distance between the reference roller and the aluminum foil roll material is adjusted for enabling a gap between the reference roller and the aluminum foil roll material to be in a measurable range of a feeler gauge; and testing is performed: the size of the gap between the reference roller and the aluminum foil roll material is observed, the proper feeler gauge is selected to carry out measurement in multiple positions of the gap to obtain measurement data of the corresponding positions, when a difference between the measurement data ofthe positions is less than or equal to 10 microns, the aluminum foil incoming material is judged to be qualified, and when the difference between the measurement data of the positions is larger than10 microns, the aluminum foil incoming material is judged to be unqualified. According to the method, the testing cost of the aluminum foil roll material and incoming material can be reduced; the quality of the aluminum foil incoming material can be rapidly and effectively judged; and the production efficiency and the production quality of enterprises are improved.

Description

technical field [0001] The invention relates to the technology in the field of aluminum-plastic film production, in particular to a method for quickly testing the quality of aluminum-plastic film and aluminum foil incoming materials. Background technique [0002] A lithium-ion battery is a rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. A lithium-ion battery is usually composed of a positive electrode, a negative electrode, a separator, an electrolyte, and an outer casing. The function of the outer packaging shell of the lithium-ion battery is to provide a closed space for containing the active material of the battery, and at the same time provide a certain degree of mechanical strength and mechanical protection. Because the aluminum-plastic film has the advantages of light weight, it can greatly increase the specific energy of the battery, and the aluminum-plastic film has great flexibilit...

AI Technical Summary

Problems solved by technology

The shape of the aluminum foil coil can directly reflect the thickness uniformity of the aluminum foil. At present, in the inspection of the incoming aluminum foil from the supplier, it is usually not measured for the shape of the incoming aluminum foil coil, and it is not relatively suitable in the market. Even if there is a corresponding inspection method, its cost is relatively high, and corresponding auxiliary equipment is required for measurement. The cost is high and the test efficiency is low, which affects the production efficiency of the enterprise.
