Abstract
The present invention provides a kind of dust-extraction units, have:Airborne dust mouth, connection external vacuum generator is so that the dust that generates is raised during cutting cut material;And dust removal port, connection external vacuum generator is so that the dust that generates is discharged via dust removal port during cutting cut material.Wherein, dust removal port is than airborne dust mouth closer to the position of cutting cut material, and the angle theta that the opening direction of dust removal port and cut material are formed is less than the angle β that the opening direction of airborne dust mouth is formed with cut material.The dust that suction-operated of the dust-extraction unit based on external vacuum generator can will be close to dust removal port is directly adsorbed to via dust removal port outside dust-extraction unit, and the dust that will be far from dust removal port is directly adsorbed to via airborne dust mouth outside dust-extraction unit, so as to improve the suction-operated of dust-extraction unit.Meanwhile external vacuum generator via airborne dust mouth to cutting cut material when the dust that generates there are one the larger active force that raises up, thus prevent dust adhesion to cut material surface, substantially improve the cut quality of cut material.
Description
Technical field
The present invention relates to field of batteries more particularly to a kind of dust-extraction units.
Background technology
Dust is always a big important citation of lithium battery security risk, and how to reduce the dust pollution of lithium battery is always
The popular problem of this industry.At present mold cutting under dust can control it is good, but with production cost reduce press
The continuous improvement of power, many lithium battery manufacturers go to sight on laser cutting technique from mold cutting.
Although laser cutting is significantly better than mold cutting in replacement cutting profile, maintenance cost etc., at this stage
The dust that is generated in cutting of laser cutting be always the greatest problem for perplexing user.In order to solve dust problem, at present
This supplementary procedure is mostly scrubbed to complete using hairbrush, but effect is less desirable.One is because without optimized design
Hairbrush by dust transfer not exclusively caused by secondary pollution, also have hairbrush in rotation process to the damage of pole piece the problems such as all
It is to solve the problems, such as at present.
The content of the invention
In view of problem present in background technology, it is an object of the invention to provide a kind of dust-extraction units, can cut
The dust of generation is effectively adsorbed during cut material, suction-operated is strong, falls back to cut material surface so as to avoid dust, changes significantly
It has been apt to the cut quality of cut material.
To achieve these goals, the present invention provides a kind of dust-extraction unit, generated when being used for cutting cut material
Dust is discharged, and is had:Airborne dust mouth, connection external vacuum generator is so that the dust that generates is raised during cutting cut material;With
And dust removal port, connection external vacuum generator is so that the dust that generates is discharged via dust removal port during cutting cut material.Wherein, remove
Dirt mouth is than airborne dust mouth closer to the position of cutting cut material, and the angle theta that the opening direction of dust removal port is formed with cut material is less than
The angle β that the opening direction of airborne dust mouth is formed with cut material.
Beneficial effects of the present invention are as follows:In dust-extraction unit according to the present invention, produced during cut material is cut
Raw dust is included close to the part of dust removal port and the part of the separate dust removal port sputtered from cut material surface.Due to dust removal port
External vacuum generator is communicated in airborne dust mouth, suction-operated of the dust-extraction unit based on external vacuum generator can will be close to
The dust of dust removal port is directly adsorbed to via dust removal port outside dust-extraction unit, and the dust that will be far from dust removal port is direct via airborne dust mouth
It is adsorbed onto outside dust-extraction unit, so as to improve the suction-operated of dust-extraction unit.At the same time, due to airborne dust mouth opening direction with
The angle β that cut material is formed is more than the angle theta that the opening direction of dust removal port is formed with cut material, therefore external vacuum generator passes through
Dust adhesion is thus prevented to quilt there are one the larger active force that raises up to the dust generated during cutting cut material by airborne dust mouth
Object surface is cut, substantially improves the cut quality of cut material.
