Problems solved by technology

At present, the commonly used control method is to use online thickness gauge and other detection equipment to monitor the coating quality in real time, but the current thickness measurement method can only measure the overall thickness of the coating, and cannot expose the problem of uneven coating , and when there is a problem with the coating thickness, the feedback speed of the coating machine from the source is also slow, and the coating effect is not good

Embodiment 1

[0055] Please refer to Figure 1-2 , Embodiment 1 of the present invention is:

[0056] A method for measuring the thickness of a pole piece, comprising the following steps;

[0057] S1, setting at least two measurement areas 11 on the transmission area of ​​the pole piece 1 along the direction perpendicular to the transmission direction of the pole piece 1;

[0058] S2. Set at least two coating ports 21 on the coating machine upstream of the measurement area 11 in a direction perpendicular to the conveying direction of the pole piece 1, and connect at least two coating ports 21 with at least two The measurement areas 11 are set in one-to-one correspondence;

[0059] S3, the coating port 21 continues to discharge the material, and the pole piece 1 is coated;

[0060] S4. The thickness measuring instrument 3 sequentially measures the measured areal density value of the slurry on the pole piece 1 in the measuring area 11, and the thickness measuring instrument 3 sends the mea...

Abstract

The invention provides a thickness measurement method for a pole piece, which can be used for more strictly controlling the coating thickness and uniformity. According to the thickness measurement method for the pole piece, a plurality of measurement regions are arranged along the transverse direction of the pole piece, and the surface density value of each region and the surface density average value of all the measurement regions are obtained, so that a coating opening of a coating machine is controlled to be correspondingly adjusted in time, and the coating thickness and uniformity can be more strictly controlled.

Description

technical field [0001] The invention relates to the technical field of coating of battery pole pieces, in particular to a method for measuring the thickness of pole pieces. Background technique [0002] Lithium-ion power batteries have been widely used in mobile communication equipment, portable mobile power storage equipment, mining power supplies, and electric vehicles due to their remarkable characteristics such as high energy density, high working voltage, long cycle life, and excellent safety performance. In recent years, with the rapid development of the field of electric vehicles, new lithium-ion power batteries have become a key factor in its development. In the production process of lithium-ion batteries, the processing of electrode plates is the key to its production. The production of electrode plates needs to go through processes such as homogenization, coating, rolling and die-cutting. Among them, the coating process is the key process in the electrode plate pr...
