Abstract

The invention provides a dust measuring assembly, and further provides a pole piece dust content measuring device and corresponding pole piece production equipment. According to the pole piece dust content measuring device, dust treatment assemblies are arranged on the two sides of a passing roller set, when a pole piece passes, dust on the edge of the pole piece is blown up through air knife assemblies, then blown-up dust is sucked in through two corresponding negative pressure dust suction hoods, and real-time detection is further conducted through dust concentration measuring equipment; inthis way, the problem that dust is difficult to detect in the actual production process can be well solved.

Description

technical field [0001] The present application relates to the technical field of new energy batteries, in particular to a pole piece dust content measuring device, a dust measuring component, and pole piece production equipment using the dust measuring component and pole piece dust content measuring device. Background technique [0002] A lot of dust will be generated during the production of lithium battery pole pieces, especially the die-cutting process and slitting process. After the dust enters the battery, it may cause risks such as piercing the diaphragm and short-circuiting the battery. Therefore, judging whether the dust on the surface of the pole piece is cleaned is a key factor in the quality of the battery. [0003] In the existing production process, the usual practice is to place a collection box under the pole piece to collect the dust falling from the pole piece. After a period of continuous production (> 8 hours), the dust in the collection box is weighed....
