Expecting less, resource utilization is high.
As Figure 6-Figure 7, the base material schematic diagram after respectively prior art and this utility model are coated with, Fig. 8 is this reality
With the base material schematic diagram after novel cross cutting.
Battery pole piece die cutting method, comprises the following steps, S1, according to the width of battery pole piece in the both sides of coating machine respectively
Arranging applying area, the gap between two applying area is for being left white district, and S2, unlatching coating machine, two applying area are to edge, base material both sides
Substrate transport direction is coated with continuously, and S3, base material pass through battery pole piece die-cutting mould 100, front edge cutting knife 160, lug cutting knife 180
Successively battery pole piece being carried out cross cutting with rear edge cutting knife 170, after cross cutting, gained waste material each falls within the cutting of lower bolster 140 correspondence
In groove 141, S4, along substrate transport direction, die-cutting mould 100 carries out continuous cross cutting to base material, obtains required form and size
Pole piece, and computer.
Battery pole piece die cutting method of the present utility model, first, by being left white and along substrate transport side in the middle of the coating of both sides
To being coated with this coating process continuously, base material is coated with continuously, then, is carried out continuously by battery pole piece die-cutting mould 100
Cross cutting.On the one hand, owing to base material is provided with two applying area, cut the applying area of both sides simultaneously and middle be left white district and can once obtain
To two pieces of pole pieces, work efficiency is high.Second aspect, the edge of base material can make full use of as pole piece main body, and lug cutting knife 180 is cut
After cutting, hollow-out parts 182 forms pole-piece pole-ear, and two edge parts 181, connecting portion 183 and extension 184 form waste material, relative to
Prior art, waste material is less, and resource utilization is high.
In S1, the width of described applying area matches with the width of battery pole piece；The width of described battery pole ear be left white
The width ratio in district is 0.85:1～0.95:1, and applying area can be utilized completely, and being left white district also can be as lug, waste material after cross cutting
Few, base material utilization rate is high, is conducive to economizing on resources.
In S3, described lug cutting knife 180 cuts the district that is left white of base material, described front edge cutting knife 160 and rear edge cutting knife 170
Cut direction each parallel to substrate transport direction, cutting base material is left white district and applying area, be left white after district cuts out lug useless
Expecting less, applying area no waste mine, base material utilization rate is high, is conducive to economizing on resources.
In S4, after front edge cutting knife 160 completes once to cut, front enumerator 142 once counts, rear edge cutting knife
After 170 complete once to cut, rear enumerator 143 once counts, and is counted by cross cutting, when mould 100 damages, and can be clear
Know this mould 100 whether within warranty coverage, with this avoid between producer and client produce about mould 100 be
The no dispute being under warranty, adds the convenience that this utility model uses.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area
For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
