Material box with dust removal device

Abstract

The invention discloses a magazine with a dust-extraction device. The magazine with the dust-extraction device comprises a magazine body, a dust-extraction mechanism, a pole piece ejecting mechanism, a pole piece box and an installation plate, and the magazine body and the pole piece ejecting mechanism are respectively arranged on the upper surface and on the lower surface of the installation plate. The dust-extraction mechanism comprises a dust collector which is arranged on the lower surface of the installation plate, the periphery of the magazine body is closed and the magazine body is provided with a cavity, the pole piece box is arranged inside the cavity, the installation plate is provided with a first through hole and a second through hole, the first through hole is matched with the pole piece ejecting mechanism, and the dust collector collects dust through the second through hole. Due to the fact that the magazine body is arranged on the upper surface of the installation plate, the dust collector is arranged on the lower surface of the installation plate, the periphery of the magazine body is closed, and the dust collector collects the dust in the magazine body through the opening at the lower end of the magazine body, and a dust collection effect is good. The magazine with the dust-extraction device can greatly reduce the phenomenon of battery cell short circuit caused by the fact that dust crosswise infects a battery cell or the dust in a pole piece impales a diaphragm, the yield of the battery cell is improved, working environment is improved, and service life of equipment is improved. The magazine with the dust-extraction device is attractive in appearance, and easy and convenient to install.

Description

technical field [0001] The application relates to the field of lithium ion battery production, in particular to a magazine with a dust removal device. Background technique [0002] Large-scale lithium-ion power battery cells are made of multi-layer cathode and anode sheets and diaphragms. Commonly used materials such as figure 1 As shown, the pole piece is placed in an open space. When the manipulator sucks the piece, the pole piece will move up and down. The floating blower mechanism 11 is used to blow away the dust on the pole piece and prevent multiple pieces from being sucked. The brush 12 prevents multiple pieces from being sucked. , Dust is sucked away by dust suction mechanism 13 with vacuum. [0003] There is following defect in above-mentioned structure: [0004] ⑴The floating blower will blow the dust on the pole piece to fly everywhere, and the blown dust will be caught on the pole piece or separator, which will easily cause the stacked battery to short circuit ...

AI Technical Summary

Problems solved by technology

[0004] ⑴The floating blower will blow the dust on the pole piece to fly everywhere, and the blown dust will be caught on the pole piece or diaphragm, which will easily lead to a short circuit of the stacked battery and affect the quality of the battery cell

[0005] (2) The dust suction mechanism 13 is behind the brush 12 and is far away from the pole piece. The entire dust suction mechanism 13 is installed on the top of the material box. The overall effect is not good, only a small amount of dust attached to the brush 2 can be sucked away
