Problems solved by technology

[0003] At present, roller coating is a relatively mature coating method, but most roller coating machines monitor the liquid level of the material tank through human eyes. Since personnel always observe the liquid level, there must be visual fatigue and deviation, and this deviation will The liquid level of the slurry is too high or even overflows, resulting in uneven coating and material waste; and because the manual stirring of the slurry cannot realize the separation of man-machine operation, resulting in unreasonable man-machine ratio and high labor costs, etc.

Abstract

The invention discloses a liquid level monitoring and automatic stirring device for lithium ion battery coating slurry. The device comprises a liquid level sensing mechanism, a slurry-feeding and flow-adjusting mechanism, a slurry stirring mechanism, and a sound-light alarm mechanism. A liquid level sensor monitors the liquid level in a material container; a signal is judged by an electrical control system; and a slurry regulating valve treats the judged result to control the flow of slurry, so that automatic control of the slurry is realized. The slurry stirring mechanism is equipped with a stirring blade, which moves in two ways of left-right swinging and automatic rotation, so that stirring without omission is totally realized. According to the invention, methods of human monitoring of the liquid level of slurry and manual mixing of the slurry of a coating machine are replaced, and the device for automatic monitoring of the liquid level and slurry stirring is provided, so that the uniformity of the liquid level of the slurry is ensured, and manual operating cost is reduced.

Description

technical field [0001] The invention relates to the field of lithium ion battery production equipment, in particular to a coating machine slurry liquid level monitoring and automatic stirring device. Background technique [0002] In the preparation process of lithium-ion batteries, electrode slurry coating technology and equipment are one of the keys to the development and production of lithium-ion batteries. Coating equipment is to uniformly coat non-Newtonian high-viscosity fluids on foils and other substrates to A coating with better uniformity is obtained. [0003] At present, roller coating is a relatively mature coating method, but most roller coating machines monitor the liquid level of the material tank through human eyes. Since personnel always observe the liquid level, there must be visual fatigue and deviation, and this deviation will As a result, the liquid level of the slurry is too high or even overflows, resulting in uneven coating and material waste; and bec...
