Description

Pole piece dust collector

Technical Field

The utility model relates to a lithium-ion battery pole piece dust removal field, concretely relates to pole piece dust collector.

Background

With the development of new energy automobiles, the requirements on lithium ion power batteries are higher and higher, and dust on positive and negative pole pieces of a lithium battery can cause short circuit, so that the self-discharge or safety accidents of the battery are caused. Because most of the lithium battery pole pieces are cut in various ways at present, dust such as scraps cannot be generated in the cutting process, and if the dust is not eliminated before assembly, the quality of a battery product is greatly influenced.

At present, the power battery industry generally adopts a manual sheet brushing mode to eliminate dust, and also adopts an automatic device to eliminate dust, but the dust eliminating effect is still deficient. The current dust removal methods include the following two methods: 1. the mode of the brush and the negative pressure is adopted, and the biggest problem of the mode is that the brush is difficult to brush dust in practice, because dust particles are very small, the brush has the risk of brushing a pole piece, and parameters such as the hardness, the consistency and the distance between the brush and the pole piece are difficult to control; the negative pressure hardly offsets the adhesive force of dust on the pole piece so as to eliminate the dust, so the effect is not good; 2. positive pressure sweeps + negative pressure dust absorption, and the risk of brushing wounded the pole piece does not exist to this mode, belongs to non-contact dust removal, and the mode result of use known at present is not good enough, and the reason is: structural design is unreasonable to lead to blowing and the dust absorption can not form effective air current, and because static reason, the dust can not blow down on the pole piece, even blow down, also forms the secondary and adsorbs easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a pole piece dust collector, its dust that can effectively eliminate the pole piece surface prevents that the secondary from adsorbing.

The technical scheme of the utility model as follows:

the utility model provides a pole piece dust collector, crosses the outside device shell of roller including enclosing to establish at the pole piece, the inside dust removal chamber that forms of device shell, the dust removal chamber divides first cavity and the second cavity that communicates each other into, the pole piece is crossed the roller and is located in the second cavity, the side of second cavity be equipped with the pole piece crosses corresponding pole piece input port of roller and pole piece delivery outlet, the top of first cavity is provided with the air knife, the below of first cavity, second cavity is equipped with the dust absorption mouth.

Furthermore, the pole piece input port and the pole piece output port are arranged up and down.

Furthermore, an inner partition plate is vertically arranged among the first chamber, the second chamber and the dust suction port, and the inner partition plate is close to the pole piece passing roller.

Furthermore, a porous plate is arranged at the position of the dust suction port, air holes communicated with the first chamber and the second chamber are formed in the porous plate, and the inner partition plate is arranged on the porous plate.

Further, a dust cover is arranged below the porous plate.

Furthermore, a dust suction pipeline is connected to the lower portion of the dust cover.

Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a divide the dust removal chamber into the first cavity and the second cavity that communicate each other, in the second cavity was located to the pole piece cross the roller, the pole piece passed the roller from the pole piece input port of second cavity side to the pole piece, again from the pole piece delivery outlet output of second cavity side, the top of first cavity sets up the air knife, the dust absorption mouth of dust removal chamber bottom is separated into through the inner baffle and is corresponded the left dust absorption mouth and the right dust absorption mouth of first cavity and second cavity respectively. At the dust absorption during operation, can form the high velocity air current between air knife and the left dust absorption mouth, under the effect of high velocity air current, can eliminate the static on lithium-ion battery pole piece surface, make the dust lose the adsorption affinity on this pole piece surface, reach the purpose of eliminating static, rethread dust absorption pipeline inhales away the dust, and the air current can enter into the space who passes the roller with the pole piece from right dust absorption mouth simultaneously, carries out secondary dust removal to lithium-ion battery pole piece surface to prevent that the dust from adhesion is on lithium-ion battery pole piece surface again. The utility model discloses can carry out twice dust removal to lithium-ion battery pole piece, have splendid dust removal effect.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

In order to explain the technical solution of the present invention, the following description is made by using specific examples.

Examples

Please refer to fig. 1 and 2, an embodiment of the present invention provides a pole piece dust removing device, including enclosing the device housing 1 arranged outside the pole piece roller 10, the inside dust removing cavity 11 that forms of the device housing 1, the dust removing cavity 11 is divided into the first cavity and the second cavity that communicate with each other, the pole piece roller 10 is located in the second cavity, the side of the second cavity is provided with the pole piece inlet 12 and the pole piece outlet 13 corresponding to the pole piece roller 10, the pole piece inlet 12 and the pole piece outlet 13 are arranged from top to bottom, the top of the first cavity is provided with the air knife 2, the lower of the first cavity and the second cavity is provided with the dust suction port, the inner partition 3 is vertically arranged between the first cavity, the second cavity and the dust suction port, the inner partition 3 is close to the pole piece roller 10, the dust suction port is provided with the porous plate 4, the porous plate 4 is provided with the air holes respectively communicated with the first cavity and the second cavity, the inner partition 3 is arranged on the porous plate 4, the dust cover 5 is provided with the dust cover, and the lower part of the dust suction pipe 6 is connected with the dust cover.

The structure principle is as follows: through dividing dust removal cavity 11 into first cavity and second cavity that communicate each other, pole piece crosses roller 10 and locates in the second cavity, pole piece 20 inputs to pole piece from the pole piece input port 12 of second cavity side and crosses roller 10, again from the pole piece delivery outlet 13 output of second cavity side, the top of first cavity sets up air knife 2, the dust absorption mouth of dust removal cavity 11 bottom is separated into the left dust absorption mouth and the right dust absorption mouth that correspond first cavity and second cavity respectively through interior baffle 3.
