Description

Technical Field

[0001] The present invention belongs to the technical field of visual inspection, and specifically relates to an agitator for lithium battery production and a method for detecting the cleanliness of the agitator. Background Art

[0002] To manufacture lithium-ion batteries, whether cylindrical, square, steel-shelled, aluminum-shelled, or soft-packed, it is generally necessary to put various powder materials or paste materials such as the main material, conductive agent, and adhesive into a stirring and dispersing device for uniform dispersion to make a non-Newtonian fluid slurry, so that the subsequent processes of lithium battery production can be carried out.

[0003] At present, in the industrial production process, it is generally necessary to continuously feed a fixed number of batches or switch to other types of batteries. When the material system is inconsistent, the stirring and dispersing device needs to be thoroughly cleaned in order to reduce the impact of dry materials or impurities on subsequent ingredients.

[0004] A Chinese utility model patent with publication number CN213915318U discloses an automatic internal cleaning structure for a lithium battery stirring and dispersing device, comprising a top plate and a stirring barrel, a hollow box fixedly connected to the center of the bottom of the top plate, a stirrer fixedly connected to the left and right sides of the center of the bottom of the inner cavity of the hollow box, a dispersion wheel fixedly connected to the right side of the bottom of the inner cavity of the hollow box, a connecting rod fixedly connected to the left side of the bottom of the hollow box, and a scraper plate fixedly connected to the left side of the bottom of the connecting rod.

[0005] Although the automatic cleaning structure inside the lithium battery stirring and dispersing device can be automatically cleaned, the structure of the stirrer is complex, and the lithium battery slurry is relatively viscous, and there are places that are difficult to clean. This cleaning structure cannot automatically determine whether it is cleaned. Summary of the invention
