Technical Field

The invention relates to the technical field of lithium battery equipment manufacturing, in particular to a pole piece edge burr cleaning spray head and a device comprising the same.

Background

At present, the new process of the lithium battery needs to cut the pole piece firstly and then roll, at the moment, because the ductility of the slurry and the base material is different, burrs (shown in figure 4) can appear on the edge of the pole piece after rolling, the traditional dust removal device comprises a brush clamping dust removal device and an air knife dust removal device, the brush clamping dust removal device depends on the brush to contact the surface of the pole piece, dust is brushed away, but the burr dust at the edge of the pole piece can not be effectively removed, the air knife dust removal relies on high-speed airflow to blow away the dust on the surface of the pole piece, the burr at the edge of the pole piece can not be removed, the direction of the high-speed air flow blown out can not be controlled, the distance between the edge of the pole piece and the air flow can not be controlled quantitatively, the edge of the pole piece is broken, and no dust deckle edge collects the mechanism, and deckle edge can pierce through the diaphragm in electric core, and the deckle edge that drops also can lead to the inside short circuit of electric core, leads to finished product battery inside to have the dust burr, and the K value is bad, and the battery disability rate is high, and single finished product battery cost increases.

Disclosure of Invention

In order to remove burr dust extending out of the edge of the pole piece due to rolling, the invention provides a burr cleaning nozzle for the edge of the pole piece.

The invention also provides a pole piece edge burr cleaning device comprising the spray head.

The purpose of the invention is realized by the following technical scheme:

the utility model provides a pole piece edge deckle edge clearance shower nozzle, includes upper plate, hypoplastron, two trachea and vacuum pipe, there is the space between upper plate and the hypoplastron in the equal level setting of upper plate and hypoplastron, two tracheas are installed respectively on upper plate and hypoplastron, and two tracheal nozzles are located the lower surface of upper plate and the upper surface of hypoplastron respectively and set up relatively, two tracheas all are connected with the air pump, vacuum pipe's one end with the left end or the right-hand member in space are connected, vacuum pipe's the other end and the evacuation machine are connected.

Further, pole piece edge deckle edge clearance shower nozzle still includes four guide blades, four guide blades horizontal installation respectively are at the leading flank and the trailing flank of upper plate and the leading flank and the trailing flank of hypoplastron.

Furthermore, the front ends of the two guide sheets positioned on the front side surface of the upper plate and the front side surface of the lower plate are flared openings.

Furthermore, the rear ends of the two guide sheets positioned on the rear side surface of the upper plate and the rear side surface of the lower plate are flared openings.

Further, the distance between the rear ends of the two guide pieces positioned on the front side surface of the upper plate and the front side surface of the lower plate is smaller than the distance between the upper plate and the lower plate, and the distance between the front ends of the two guide pieces positioned on the rear side surface of the upper plate and the rear side surface of the lower plate is smaller than the distance between the upper plate and the lower plate.

Furthermore, a regulating valve is arranged between each air pipe and the air pump.

Further, the direction of the air flow sprayed by the nozzle faces the direction of the vacuum pipeline and forms an included angle of 45 degrees with the horizontal plane.

The utility model provides a contain pole piece edge deckle edge cleaning device of pole piece edge deckle edge clearance shower nozzle, including guide post, two sliders and two pole piece edge deckle edge clearance shower nozzle, two pole piece edge deckle edge clearance shower nozzle sets up relatively and installs respectively on two sliders, the equal sliding connection of two sliders is on the guide post that the level set up, the guide post just fixes on external fixing spare with walking tape direction mutually perpendicular of pole piece.

The invention has the beneficial effects that:

1. the invention can effectively solve the problem of the edge burrs of the pole piece in the new process, and can remove the edge burrs which cannot be removed by the traditional mode;

2. the K value of the battery core is reduced, the yield of the battery is improved, the cost of a single finished battery is reduced, and the safety of the battery is improved;

3. the air pressure value, the air quantity and the air outlet angle can be correspondingly adopted for quantifying different pole piece widths and different coatings, the adjustment is convenient, and the universality is strong;

4. compressed air is used as power, the electrode plate is not contacted in the hair edge removing process, the electrode plate is not damaged, and the safety is higher.
