Box for cleaning electrode plates of lithium ion battery

The utility model discloses a box for cleaning electrode plates of a lithium ion battery, which can be collected in time. One side of the box body is open; a positive-pressure air source is respectively connected with a left channel and a right channel; the left channel and the right channel are respectively connected with an air inlet pipeline; each air inlet pipeline is opened toward the top parts of two side walls of the box body; the bottom of the end wall of the box body is connected with an air suction pipeline; one end of the air suction pipeline is connected with negative-pressure equipment. In the utility model, the top positive-pressure air source blows off coating fines cleaned off the electrode plates of the lithium ion battery, and then the coating fines blown off are sucked by the negative-pressure equipment of the air suction pipeline connected with the bottom of the end wall of the box body, thereby the secondary pollution to the electrode plates of the lithium ion battery is avoided.
