The gap that swollen and contraction may result between electrode is uneven, so that battery performance be caused to decline；Although takeup type battery core is suitable
For cylindrical battery, but when it applies to rectangular aluminum-shell battery, it just will appear pole piece easily in rupture, electrode activity
The defects such as material falls back, space utilization rate be low；In addition, the tension of the battery core front and side is inconsistent, internal-response will lead to
Unevenly；The disadvantages of there are also pole pieces simultaneously compared with long, the internal resistance of cell is big, is unfavorable for high rate charge-discharge.And it is stacked cell performance
It is significantly promoted on energy compared to coiled battery, but currently without sizable application.
Continuous positive and negative electrode pole piece is first cut into single pole piece one by one, then the shape on single pole piece by laminated cell needs
At tab, i.e. film-making is carried out separately with slice, needs to put into a large amount of manpower and material resources, not only high production cost, also result in life
Produce inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of continuous integrated cutter device of single pole piece in laminated cell, the dresses
It sets and can solve deficiency in the prior art.
To achieve the above object, the utility model uses following production program:
The continuous integrated cutter device of single pole piece in a kind of laminated cell, including for pole piece roll, driven roller and more
A support roller for being used to support pole piece；Further include first laser cutter and second laser cutter arranged side by side, is located at the
The front and back ends of dual-laser cutter are respectively provided with the clamping limb of clamping pole piece, and the rear end of the clamping limb passes through linking arm
It is slidably connected with sliding rail, the clamping limb, which is connected with driving mechanism, makes clamping limb reciprocatingly slide along sliding rail.
Wherein driving mechanism includes cylinder, oil cylinder or motor, as long as clamping limb can be driven to reciprocatingly slide along sliding rail.
Further scheme is respectively equipped with dust cleaning case immediately below first laser cutter and second laser cutter.
Further scheme, the pole piece in front of first laser cutter pass sequentially through deduster, jockey pulley and deviation rectification roller.
When the present apparatus operates, first pole piece roll is loaded on unreeling structure, pole piece is supported and is passed through by support roller
Driven roller is driven, while also passing sequentially through deduster, jockey pulley and deviation rectification roller, finally enters clamping limb, two clamping limbs
When clamping pole piece end, first laser cutter and second laser cutter are worked at the same time, and first laser cutter is first by foil
Material is cut into tab block, and second laser cutter separates tab block and front, tab is cut into, to form single pole piece.It drives
Motivation structure driving clamping limb slides backward along sliding rail, and clamping limb realizes single pole piece blanking after unclamping；Then driving mechanism drives
Clamping limb reversely slides into forward initial position along sliding rail, clamps the pole piece transmitted again, realizes the system to pole piece
Piece and slice work.So the present apparatus realize pole piece be continuously finished the unreeling of coiled strip, dedusting, tension force, correction, film-making,
Slice, positioning blanking integrated process.
The present apparatus realizes pole piece and is continuously finished the unreeling of coiled strip, dedusting, tension force, correction, film-making, slice, blanking
Integrated process, and guarantee the integrality of battery core, the production efficiency of production single pole piece cutting is greatly improved.This is practical new
The beat upper limit of uneven, the traditional lamination of the winding tension that type breaks conventional winding equipment, device efficiency is higher, and than conventional roll around
Formula battery core is upper advantageous in the processing of NG product, it can be achieved that film-making, the integrated production process of slice.Laminated batteries manufacture is greatly reduced
Equip manpower demand and efficiency requirements.

Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, in a kind of laminated cell single pole piece continuous integrated cutter device, including for pole piece roll 1, drive
Dynamic roller 7 and multiple support rollers 3 for being used to support pole piece；It further include first laser cutter 10 and second laser arranged side by side
Cutter 11 is respectively provided with the clamping limb 12 of clamping pole piece 2, the folder positioned at the front and back ends of second laser cutter 11
The rear end of gripping arm 12 is slidably connected by linking arm with sliding rail 13, and the clamping limb 12, which is connected with driving mechanism 9, makes clamping limb 12
