Abstract
The utility model discloses a lithium ion battery pole piece cross cutting machine knife mould belongs to the lithium - ion battery technology field. The utility model discloses a following technical scheme realizes: lithium ion battery pole piece cross cutting machine knife mould, including bottom plate and cutting die, a plurality of cutting dies set up side by side on the bottom plate, a plurality of round holes of the uncovered position of the cutting die of bottom plate distribution, and open the bottom plate position at cutting die place has cross gap 201, the bottom plate is the bakelite plate. The utility model has the advantages of: the cross gap communicates with each other outside air and die -cut pole piece upper portion, when the pole piece is die -cut, can reduces the cutting die and to the absorption problem of pole piece, effectively solve cross cutting static and inhaled piece, indiscriminate piece phenomenon. The deformation of bottom plate has been avoided to the round hole of bottom plate equipartition, has improved life.
Description
Technical field
The utility model discloses a kind of electrodes of lithium-ion batteries die-cutting machine cutting die, belong to technical field of lithium ion.
Background technology
Large Copacity, big current lithium ion battery more and more obtain broad development, and the lithium ion battery energy of laminar is large, and good rate capability, has extended cycle life, and is widely used in dynamic field.Wherein, film-making operation is the lithium ion battery important procedure of laminar; the die-cut tablet form cost of die-cutting machine plank cutting die machinery is low; remodel conveniently; be widely used in the lithium ion battery preparation of laminar; but place yielding when plank cutting die area is larger for a long time, in die cutting process, Yin Moqie electrostatic inhales sheet, random sheet phenomenon is also a lot.If that can reduce plank cutting die on the basis not increasing plank cutting die cost shelves distortion, electrostatic suction sheet, random sheet problem, very important for the processing of raising lithium ion battery.
Summary of the invention
For the problems referred to above, the utility model provides a kind of lithium ion battery die-cutting machine cutting die, with reduce cutting die shelve distortion, electrostatic inhales sheet, random sheet problem, improves the processing characteristics of lithium ion battery.
To achieve these goals, the utility model adopts following technical scheme to realize:
Electrodes of lithium-ion batteries die-cutting machine cutting die, comprises base plate and cutting die, and multiple described cutting die is disposed side by side on base plate, and the cutting die uncovering position of base plate distributes multiple circular hole, and the base plate position at cutting die place has cross gap 201, and described base plate is bakelite plate.
As preferably, the diameter of circular hole is 3-8mm, and the spacing between circular hole is 10-15mm.
The utility model has the advantage of: outside air communicates with die-cut pole piece top by cross gap, when pole piece is die-cut, the absorption problem of cutting die to pole piece can be reduced, efficiently solve cross cutting electrostatic and inhale sheet, random sheet phenomenon.The uniform circular hole of base plate avoids the distortion of base plate, improves service life.
Accompanying drawing explanation
The electrodes of lithium-ion batteries die-cutting machine cutting die planar structure schematic diagram that figure .1 provides for the utility model;
Wherein: 1, base plate, 2, cutting die, 101, circular hole, 201, cross gap.
specific implementation method
Also by reference to the accompanying drawings the technical solution of the utility model is further described below by embodiment.
As shown in Figure 1, electrodes of lithium-ion batteries die-cutting machine cutting die, this lithium ion battery die-cutting machine cutting die is made up of base plate 1 and cutting die 2, wherein, base plate 1 is common bakelite plate, base plate is distributed with multiple circular hole 101, base plate circular hole skeleton strengthens cutting die, and what decrease cutting die shelves distortion.The bottom parts that cutting die 2 surrounds, namely the corresponding bottom parts of pole piece is carved with cross gap 201, because outside air communicates, when pole piece is die-cut with die-cut pole piece top by cross gap 201, the absorption problem of cutting die to pole piece can be reduced, efficiently solve cross cutting electrostatic and inhale sheet, random sheet phenomenon.
The diameter of circular hole is 3-8mm, and the spacing between circular hole is 10-15mm.Open circular hole by base plate, the intensity of base plate can be strengthened, avoid bottom deformation.
