The positive and negative electrode pole piece of lithium ion battery is made of ultra-thin aluminium foil or copper foil, need to continuously be cut in foil two sides
Concavo-convex tab is cut out, is used for later period lithium ion battery conduction, is continuously cut using laser cutting device at present.Laser
When cutting, more dust can be generated, therefore to be dusted by the way of negative-pressure ward to foil in cutting position.Due to
Negative-pressure ward will cause foil vibration and foil out-of-flatness itself will also result in shake, and it is inclined that these factors will lead to foil
The effect that cutting is influenced from laser spot causes to can't cut, burr becomes larger phenomena such as big with heat affected area.
Currently, some carries out support using idler wheel made of Teflon material or sheet metal in order to solve the problems, such as this.It is special
Although fluorine dragon material is resistant to laser, but high temperature resistance is bad, and Teflon is softer, cuts metallic particles, the dust of generation
It can be embedded, destroy its resistance to laser activity, therefore the service life is extremely short, just need to carry out after the general foil for cutting about 3000mm long
Cleaning or replacement.Sheet metal is not resistant to laser energy, therefore the support that can only misplace (is held on the path that no laser passes through
Support), damping effect is unobvious, and has the shortcomings that metallic dust adsorbs, and frequent progress is needed to clear up or replace.
Another method is exactly the power for increasing laser, increases laser energy, to alleviate pole piece slight jitter institute
Caused by focal length variations.Due to laser energy surplus, cutting area heat-affected zone is caused to increase, under cutting section quality is obvious
Drop, and also will cause the waste of energy.
