Description
Technical field
The utility model relates to battery pole piece technical field of processing equipment, refers in particular to a kind of battery pole piece die cutting die.
Background technology
Lithium ion battery is the new generation of green high-energy battery of performance brilliance, one of emphasis becoming hi-tech development.Lithium ion battery has following characteristics: high voltage, high power capacity, low consumption, memory-less effect, nuisanceless, volume is little, internal resistance is little, self discharge is few, cycle-index is many.Because of its These characteristics, lithium ion battery has been applied to numerous civilian and military fields such as mobile phone, notebook computer, video camera, digital camera.
The pole piece of lithium battery in process of production, needs to carry out die-cut to battery pole piece, then die-cut good pole piece blanking, packaging etc.In prior art, two molds are adopted to carry out die-cut to the pole piece of battery, first set mould rushes the lug part of pole piece, after lug partial die cut completes, obtain interval waste material and abandon, connecting gear continues to transmit pole piece, and pole piece is through the second mold, this second mold thrusts pole piece, thus obtains pole piece product.Adopt this die-cut mode, need two molds, the manufacturing cost of mould is high, the volume of whole die cutting device is comparatively large, complex structure, twice die-cut pole piece, there are cumulative errors, the size and dimension precision of pole piece is difficult to ensure, the mold defect of existing die-cut pole piece is obvious.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, the die cutting die that volume is little, and this die cutting die is to the disposable punching molding of pole piece, and die-cut speed is fast, improve production efficiency, and pole piece form accuracy is high, ensures the quality of product.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of battery pole piece die cutting die, comprise upper die component and lower mold assemblies, it is characterized in that: also comprise cutting die plate, this cutting die plate is provided with cutting knife, the shape of this cutting knife and pole piece corresponding by the interval waste material cut.
Preferably, described cutting knife comprises and cuts lug portion and cut with this cutting portion that lug portion is connected.
Another is preferred, and described cutting knife comprises left cut lug portion and the right cut lug portion that correspondence arranges lug both sides.
Wherein, described cutting knife also comprises lug cutting portion, and this lug cutting portion is connected with described left cut lug portion and right cut lug portion respectively.
Wherein, connected two limits, described cutting knife bottom surface are excessive with fillet.
The beneficial effects of the utility model: in actual applications, cutting die plate is installed on upper die component, upper die component with cutting die plate move up and down carry out die-cut, the shape of cutting knife and pole piece corresponding by the interval waste material cut, thus make that this cutting knife is disposable cuts all waste materials, the shaping pole piece of one cutter, error is little, die cutting accuracy is high, avoid repeatedly die-cut and produce accumulated error, simplify the structure of die cutting die, the size of cutting knife and interval waste material adapts, have nothing to do with pole piece finished product, therefore not by the restriction of finished product size, whole mould can be done as far as possible little, be convenient to installation and the placement of mould, decrease die-cut processing step and the quantity of mould, reduce production cost, improve production efficiency simultaneously, there is very strong practicality.

Detailed description of the invention
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
embodiment one.
As shown in Figure 1 to Figure 3, a kind of battery pole piece die cutting die, comprises upper die component 1 and lower mold assemblies 2, also comprises cutting die plate 3, and this cutting die plate 3 is provided with cutting knife, the shape of this cutting knife and pole piece corresponding by the interval waste material 80 cut.
In actual applications, cutting die plate 3 is installed on upper die component 1, upper die component 1 with cutting die plate 3 move up and down carry out die-cut, the shape of cutting knife and pole piece corresponding by the interval waste material 80 cut, thus make that this cutting knife is disposable cuts all waste materials, the shaping pole piece of one cutter, error is little, die cutting accuracy is high, avoid repeatedly die-cut and produce accumulated error, simplify the structure of die cutting die, the size of cutting knife and interval waste material 80 adapts, have nothing to do with pole piece finished product, therefore not by the restriction of finished product size, whole mould can be done as far as possible little, be convenient to installation and the placement of mould, decrease die-cut processing step and the quantity of mould, reduce production cost, improve production efficiency simultaneously, there is very strong practicality.
In the present embodiment, described cutting knife comprises to be cut lug portion 4 and cuts with this cutting portion 5 that lug portion 4 is connected.As shown in Figure 3, described interval waste material 80 comprise lug waste material breach 20 place and cut off waste material limit 30 place by blank, described in cut the shape in lug portion 4 corresponding with the shape of lug waste material breach 20, the shape of cutting portion 5 is corresponding with the shape on cut-out waste material limit 30.
