Description
Technical field
The present invention relates to the pole piece die-cutting apparatus that a kind of employing ozone is processed, belong to lithium battery automation equipment technology neck
Domain.
Background technology
Lithium ion battery, due to having the advantage of high voltage, high-energy-density and long circulation life, becomes range of application
One of wide secondary cell, the use safety of high request, efficient manufacture method, all manufacturing process is proposed with higher wanting
Ask.
The traditional processing mode of electrodes of lithium-ion batteries is using the conventional processing equipment such as die-cutting machine, banding machine, this biography
The processing mode of system has abrasion to equipment in process, needs to regularly replace cutting die, processing cost is higher, meanwhile, electricity
Pond pole piece occurs that crimping, facet are unsmooth, the product defects such as jagged.
The widely used laser instrument of industrial market cuts to pole piece at present, solves the said goods quality problems, due to laser
Processing is noncontact processing, and the cost of the equipment consumptive material substantially reducing improves working (machining) efficiency.But because pole piece is composite
Make, the ingredient of positive pole is positive electrode (as LiFePO4)+conductive agent+binding agent (pvdf)+collector (aluminium foil), bears
The ingredient of pole is graphite+conductive agent+thickening agent (cmc)+binding agent (sbr)+collector (Copper Foil), when using cut,
A large amount of dust not only can be revealed, pole piece occurs the phenomenon that coat shrinks simultaneously, the middle electrode layer of cut portion has naked
Dew phenomenon, such defect can bring potential safety hazard to product.
Content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, provides the pole piece cross cutting that a kind of employing ozone is processed
Device, this device energy effectively solving is due to cutting the problem that the dust that lug is formed leads to battery core to be scrapped.
The technical scheme providing according to the present invention, the pole piece die-cutting apparatus that a kind of employing ozone is processed it is characterised in that: bag
Include dedusting mechanism 4, laser head 6, described laser head 6 is located at dedusting mechanism 4 side, described dedusting mechanism 5 includes dedusting housing, removes
Dirt case inside is provided with the breach passing through for pole piece 1, and described dedusting housing is provided with and supplies laser head towards the side plate of laser head 6
For cutting the laser channeling of lug, described dedusting hull outside is connected with air intake device, the pole piece 1 of described dedusting case inside
It is respectively provided on two sides with for the ozone generator 5 spraying ozone at cutting lug.
Further, the pole piece both sides of dedusting case inside are relatively provided with the dust producing cutting lug respectively and blow to suction
The left air knife of wind apparatus and right air knife.
Further, described dedusting mechanism 4 is two groups, and two groups of dedusting mechanisms 4 are oppositely arranged on pole piece two side ends.
Further, described ozone generator 5 arranges jet end, described jet end opens up least one set fumarole,
Described fumarole is towards lug cut place.
The method have the advantages that
The present invention passes through laser fly-cutting lug, and sprays lug cut place using ozone, utilizes left air knife and right wind simultaneously
Knife and air intake device are processed to the dust of cutting lug formation, thus being avoided that dust leads to the problem that battery core is scrapped.
Brief description
Fig. 1 is signal Fig. 1 of this pole piece cross cutting.
Fig. 2 is signal Fig. 2 of the present invention.
Fig. 3 is signal Fig. 3 of the present invention.
Specific embodiment
With reference to concrete accompanying drawing, the invention will be further described.
As shown in FIG. 1 to 3: described pole piece die-cutting apparatus include pole piece 1, lug 2, pre-cut blank 3, dedusting mechanism 4, smelly
Oxygen maker 5, laser head 6, garbage collection mechanism 7, frame 8.
In the description of detailed description below, with Fig. 2 dedusting mechanism 4 outwards as outside, with the dedusting mechanism in Fig. 2
4 is inwardly inner side.
Two groups of laser heads 6 and two groups of dedusting mechanisms 4 are adopted, pole piece 1 is through excessive in pole piece die-cutting apparatus embodiment of the present invention
Individual roller 9 of crossing transmits and passes through the breach of dedusting mechanism 4, and two groups of dedusting mechanisms 4 are oppositely arranged, dedusting hull outside and air intake device
It is connected,
The pole piece both sides of dedusting case inside are provided with the left wind that the dust producing cutting lug blows to air intake device respectively relatively
Knife and right air knife, each dedusting mechanism 4 side is provided with laser head 6, laser head 6 just to dedusting mechanism 4 on side plate be provided with
It is used for cutting the laser channeling of lug for laser head, laser head 6 is carried out according to the such as dotted line position of Fig. 1 to it according to control system
Carry out excising pre-cut blank 3, form lug 2, the dust being formed in cutting will be coordinated using air intake device, left air knife and right air knife
Action, extracts dust.
The pole piece 1 of described dedusting case inside is respectively provided on two sides with for generating to the ozone spraying ozone at cutting lug
Device 5, described ozone generator 5 arranges jet end, described jet end opens up two groups of fumaroles, described every group of fumarole direction
Lug cut place, ozone is blown to cut place by this fumarole respectively, and the strong oxidation of ozone makes the cut edge of pole piece
The exposed surface of upper thawing is direct oxidation into the non-conductive material such as copper oxide and aluminium sesquioxide, also can with coating on thickening
Agent, binding agent merge, and cover at cut place, play a protective role, and unnecessary ozone will be taken away by air intake device.
