Description

The pole piece die-cutting apparatus that a kind of employing ozone is processed

Technical field

The utility model is related to the pole piece die-cutting apparatus that a kind of employing ozone is processed, and belongs to lithium battery automation equipment technology Field.

Background technology

Lithium ion battery becomes range of application most due to the advantage with high voltage, high-energy-density and long circulation life One of wide secondary cell, the use safety, efficient manufacture method of high request all propose higher wanting to production process Ask.

The traditional processing mode of electrodes of lithium-ion batteries is to use the conventional processing equipments such as die-cutting machine, banding machine, this biography The processing mode of system has in process abrasion to equipment, needs to regularly replace cutting die, and processing cost is higher, meanwhile, electricity Pond pole piece occurs that crimping, cut surface are unsmooth, jagged to wait product defects.

At present the widely used laser instrument of industrial market cuts to pole piece, the said goods quality problems is solved, due to laser Processing is noncontact processing, the cost of the equipment consumptive material for substantially reducing, and improves working (machining) efficiency.But because pole piece is composite Make, the part of positive pole is positive electrode（Such as LiFePO4）+ conductive agent+adhesive（PVDF）+ collector（Aluminium foil）, bear The part of pole is graphite+conductive agent+thickener（CMC）+ binding agent（SBR）+ collector（Copper Foil）, when using laser cutting, A large amount of dust can not only be revealed, while pole piece occurs the phenomenon that coat shrinks, the electrode layer in the middle of cut portion has naked Dew phenomenon, such defect can bring potential safety hazard to product.

The content of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided the pole piece cross cutting that a kind of employing ozone is processed Device, the device energy effectively solving is due to cutting the problem that the dust that lug is formed causes battery core to be scrapped.

According to the technical scheme that the present invention is provided, the pole piece die-cutting apparatus that a kind of employing ozone is processed, it is characterised in that：Bag Dedusting mechanism, laser head are included, the laser head is located at dedusting mechanism side, and the dedusting mechanism includes dedusting housing, dedusting shell In vivo side is provided with the breach passed through for pole piece, and the dedusting housing to be provided be used for for laser head and cuts towards the side plate of laser head The laser channeling of lug is cut, the dedusting hull outside is connected with air intake device, the pole piece both sides point of the dedusting case inside It is not provided with for cutting the ozone generator that ozone is sprayed at lug.

Further, the pole piece both sides of dedusting case inside are provided with for the dust that cutting lug is produced to blow to suction respectively relatively The left air knife and right air knife of wind apparatus.

Further, the dedusting mechanism is two groups, and two groups of dedusting mechanisms are oppositely arranged on pole piece two side ends.

Further, jet end is set on the ozone generator, least one set fumarole, institute is opened up in the jet end Fumarole is stated towards lug cut place.

The invention has the advantages that：

The present invention by laser fly-cutting lug, and using ozone injection lug cut place, at the same using left air knife and Right air knife and air intake device are processed cutting the dust that lug is formed, so as to be avoided that dust causes what battery core scrapped to ask Topic.

Description of the drawings

Fig. 1 is signal Fig. 1 of this pole piece cross cutting.

Fig. 2 is signal Fig. 2 of the present utility model.

Fig. 3 is signal Fig. 3 of the present utility model.

Specific embodiment

With reference to concrete accompanying drawing, the invention will be further described.

As shown in FIG. 1 to 3：The 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, dedusting mechanism 4 is outside as outside with Fig. 2, with the dedusting mechanism in Fig. 2 4 is inwardly inner side.

Using two groups of laser heads 6 and two groups of dedusting mechanisms 4 in pole piece die-cutting apparatus embodiment of the present invention, pole piece 1 is through more Individual roller 9 of crossing is transmitted and 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,

Respectively the dust that cutting lug is produced is blowed to air intake device by relative being provided with for the pole piece both sides of dedusting case inside Left air knife and right air knife, each side of dedusting mechanism 4 is provided with laser head 6, laser head 6 just to dedusting mechanism 4 on side plate on To be provided be used for for laser head and cut the laser channeling of lug, laser head 6 is carried out according to the such as dotted line of Fig. 1 according to control system to it Position carries out cutting off pre-cut blank 3, forms lug 2, and the dust formed in cutting will be using air intake device, left air knife and right air knife Interoperation, extracts dust.

The pole piece 1 of the dedusting case inside is respectively provided on two sides with for generating to cutting the ozone that ozone is sprayed at lug Device 5, arranges jet end on the ozone generator 5, two groups of fumaroles, every group of fumarole direction are opened up in the jet end Ozone is blown to cut place by lug cut place, the 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 cupric oxide and alundum (Al2O3), also can be with the thickening in coating Agent, binding agent are merged, and are covered in cut place, play a protective role, and unnecessary ozone will be taken away by air intake device.
