Description
Technical field
The invention belongs to lithium battery manufacturing technology field more particularly to a kind of pole piece blanking units and its control methods.
Background technique
Lithium battery is the generation green high-capacity battery of performance brilliance, and application field is extensive.The pole piece of lithium battery is in production
In the process, it needs to be punched out battery pole piece, then the pole piece being punched is packed.
With reference to Fig. 1, in the prior art, artificial tab and the bottom for cut using trimming cutter 3 and the first cutter 1 material
Then side cuts off fragment using the second cutter 2.But the prior art is easy to cause pole piece that fillet is irregular, this is for battery
Charge and discharge it is easily dangerous, it is necessary to the problem of forbidding, and a knife caused to be cut into two waste product tabs.
Summary of the invention
The purpose of the present invention is to provide a kind of pole piece blanking units and its control methods, it is intended to which solution is justified in the prior art
The technical issues of angle cuts deviation, and security risk is generated in battery charging and discharging.
To achieve the above object, technical scheme is as follows: pole piece blanking units, including tab cutter, severing are cut
Knife and repair bevel tool.The tab cutter includes two punch-nose angle cutting edges, and the severing cutter has two punch-nose angle cutting edges, described
Repairing bevel tool has a die entrance cutting edge.
Preferably, the severing cutter blade length is consistent with the material width cut.
Preferably, the tab cutter, the severing cutter are consistent with the fillet specification for repairing bevel tool, so that described
Severing cutter can carry out cutting fragment along the cross section of the material.
Preferably, the tab cutter, the severing cutter and the fillet for repairing bevel tool are in the same size, so that described
Pole piece cuts out the tab of rule, improves quality product rate.
The control method of above-mentioned pole piece blanking units, includes the following steps:
(1) the tab cutter respectively symmetrically cuts one in the material two sides using the material center axis as symmetry axis
Rectangle, the rectangle have two fillets for being provided close to material center axis side；
(2) the severing cutter cuts off fragment along the two rectangular centre axis；
(3) part of the non-fillet in two sides up and down for repairing the pole piece that bevel tool is respectively arranged on after the fragment is repaired
It cuts.
Pole piece blanking units structure of the present invention is simple, uniformly cuts out the fillet of specification, reduces waste product tab rate,
Pole piece quality product rate is improved, the security risk for piercing through diaphragm is reduced.
