Adjustable paste box

Abstract

The invention discloses an adjustable paste box, and belongs to the field of coating method research. The adjustable paste box comprises a shell, material collecting mechanisms, two rubber pads, an adjusting mechanism and two scrapers; the shell is in a cuboid shape, a concave cavity is formed in the top surface of the shell, the shell comprises two identical sub-shells, each sub-shell comprises abottom plate, side plates and two mutual paralleled vertical plates, wherein the side plates and the two vertical plates are vertically arranged on the bottom plate, the side plates are vertically connected with any vertical plate, and a clamping mechanism is arranged between the two vertical plates forming the side faces of the shell; the material collecting mechanisms are arranged inside the shell; the two rubber pads are arranged, the cross sections of the rubber pads are in U shapes, and the two rubber pads are arranged between the two sub-shells; the adjusting mechanism is provided withguide rails and sliding blocks, and the guide rails are fixedly arranged at the top of the shell; and the two scrapers are symmetrically arranged on two sliding blocks, and the scrapers are arranged in parallel with the middle section parts of the rubber pads. The adjustable paste box is simple in structure and convenient to operate, the contact area between paste liquid and a pole piece can be ensured, and then the coating quality of the pole piece is guaranteed.

Description

technical field [0001] The invention belongs to the field of coating method research, and more specifically relates to an adjustable slurry box. Background technique [0002] Due to its good cycle stability, specific capacity and long life, the battery has become one of the new energy sources in the 21st century. It is widely used in electric vehicles, electric bicycles and various electric equipment. Therefore, the safety performance of the battery And the performance requirements are getting higher and higher. [0003] In the production process of the battery, it is necessary to make the positive and negative electrode slurry, and then coat the slurry on the corresponding pole piece, so as to improve the electrochemical performance of the battery. However, during the coating process, the uniformity and thickness of the coating on the pole piece will greatly affect the electrochemical performance of the final product, and strict control is required during the coating proce...

AI Technical Summary

Problems solved by technology

However, when the existing slurry box is coating the pole piece, as time goes by, the feed liquid is continuously coated on the pole piece, the feed liquid in the slurry box decreases, the surface height of the feed liquid decreases, and the pole piece is The time elapsed in the feed liquid is reduced, resulting in inconsistent coating uniformity of the front and rear pole pieces, which directly affects the coating effect of the pole piece and the electrochemical performance of the final product, not only resulting in a high defective rate and a decrease in production efficiency, but also It leads to the waste of slurry; in addition, after the pole piece is coated with the material liquid, the thickness and uniformity of the material liquid on the front and back sides of the pole piece cannot be quickly guaranteed, which greatly affects the quality of the product and the efficiency of production
