Description

Lithium ion battery die-cutting machine
Technical field
This utility model relates to a kind of lithium ion battery die-cutting machine.
Background technology
In lithium ion battery production process, especially in pole piece cutting process, pole piece easily adheres to the dust foreign body such as copper scale, aluminum bits.On the one hand, the dust foreign body that granule is less is floating in atmosphere, affect air purity, easily affected healthy in operator's suction body, on the other hand, after positive/negative plate is assembled into battery, these dust are easily caused inside battery and produce micro-short circuit, thus reduce battery performance and cause potential safety hazard, therefore the removing of dust is particularly important.
Existing dust removal device of pole piece is usually and sets air jet system above pole piece, negative pressure dust collect plant is set in the lower section of pole piece, the airflow direction formed between air jet system and dust collect plant is perpendicular to the upper surface of pole piece, in die-cutting machine, transporter moves forward with the pole piece of horizontal, the upper-lower position of pole piece is provided with blanking mechanism, for avoiding equipment to block or interfering dedusting, pole piece must be removed die-cutting machine in use, the top of dust collect plant must be provided with the supporting construction breathed freely, and the dust collecting opening of dust collect plant is greater than the puff prot of pole-piece area and air jet system, make dust arrester be coated with by pole piece comprehensively, dedusting otherwise can be caused uneven or pole piece side edge portions cleans halfway problem, after pole piece dedusting, also again pole piece is retracted die-cutting machine, it is unfavorable for on-line continuous operation, and structure is complex.
Utility model content
What the purpose of this utility model was to provide a kind of simple in construction can the lithium ion battery die-cutting machine of dedusting online.
For achieving the above object, the technical scheme of this utility model lithium ion battery die-cutting machine is: lithium ion battery die-cutting machine includes that the stamping-out position for stamping-out pole piece, the side of described stamping-out position are provided with for from the lateral blowning installation blowing it of pole piece.
The side relative with described blowning installation of described stamping-out position is provided with dust collect plant, is formed for the dedusting air-flow through pole piece between described blowning installation and dust collect plant.
The flow direction of described dedusting air-flow is for parallel with the plane at pole piece place.
Described dust collect plant includes non-woven fabrics dust binding plate, and the plate face of non-woven fabrics dust binding plate is vertical with the flow direction of described dedusting air-flow, and the side deviating from described blowning installation of non-woven fabrics dust binding plate is Open architecture.
Described integrating device includes negative-pressure air fan and the disposal box being connected on negative-pressure air fan.
The beneficial effects of the utility model are: in use, it is blown by the side of the pole piece that blowning installation is located at stamping-out, on the one hand the equipment at pole piece upper and lower can be avoided, it is not necessary to pole piece is removed from production equipment immigration, it is possible to realize the online dedusting to pole piece, on the other hand, without separately setting the supporting construction to pole piece, without making dust arrester be all coated with by pole piece, the dust on pole piece can be removed, simple in construction, easy to use.
Further, the offside at blowning installation arranges dust collect plant, by dedusting air-flow, the dust of the pole piece that blows off is delivered to dust collect plant and is collected processing.
Further, utilize the ability of the adsorption of dust that non-woven fabrics is good, it is achieved directly filtering dedusting air-flow, purify air;The dorsal part of non-woven fabrics dust binding plate uses Open architecture, communicates with battery production environment, forms benign cycle, it is possible to reduce the dust content in battery production environment.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of dust arrester in this utility model lithium ion battery die-cutting machine;
Fig. 2 is the environment powder dust particle number change curve chart after using the dust arrester in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
The embodiment 1 of lithium ion battery die-cutting machine of the present utility model, lithium ion battery die-cutting machine includes that the upper and lower of stamping-out position is provided with blanking mechanism for the stamping-out position of stamping-out pole piece 1 with for the transporter driving pole piece 1 to move forward.As it is shown in figure 1, pole piece 1 is positioned at stamping-out position, the left and right sides of stamping-out position is provided with relative blowning installation 2 and dust collect plant 3, blowning installation and dust collect plant define the dust arrester to pole piece.Blowning installation 2 includes the malleation wind regime blown towards pole piece 1, dust collect plant 3 is non-woven fabrics dust binding plate, dedusting air-flow is formed between blowning installation 2 and dust collect plant 3, dedusting parallel current ground is through pole piece 1, i.e. gas flow direction is parallel to the plane at pole piece 1 place, the most vertically blows on non-woven fabrics dust binding plate.The side towards blowning installation 1 of non-woven fabrics dust binding plate is provided with diversion fan, and the side deviating from blowning installation 1 is Open architecture, communicates with battery production environment.
During use, during sucker in die-cutting machine puts into rewinding box with die-cut good pole piece, dust impurities pole piece 1 and about is blowed to the non-woven fabrics dust binding plate of pole piece 1 opposite side by the air-flow of blowning installation 2 blowout from the side of pole piece 1, owing to non-woven fabrics has the ability of good adsorption of dust, dust in air is adsorbed by its surface when through non-woven fabrics, air after purification enters battery production environment, defines benign cycle.Using particle counter to measure environment dust content, obtain curve chart as shown in Figure 2, wherein, abscissa express time, vertical coordinate represents number of particles, it can be seen that through dedusting, dust in air number of particles is decreased obviously and tends towards stability.
The embodiment 2 of lithium ion battery die-cutting machine of the present utility model, as different from Example 1, dust collect plant includes negative-pressure air fan and the disposal box being connected on negative-pressure air fan, is provided with air filter in disposal box, and air filter can be the filtering material that absorbability is general.
In other embodiments, only consider pole piece dedusting, it is also possible to save dust collect plant.
In other embodiments, can also there is inclination angle relative to pole piece place plane in the direction of dedusting air-flow.
