Description
Technical field
The present invention relates to diaphragm paint-on technique fields, and in particular to a kind of diaphragm for lithium ion battery coating unit.
Background technique
Diaphragm primarily serves isolation positive and negative anodes, while the effect as lithium ion tunnel in lithium ion battery.To battery
Safety effects it is significant.The application of requirement with to(for) the bulking value density and content volume density of lithium ion battery is more next
Higher, diaphragm also gradually becomes thin, and diaphragm coating gradually becomes trend.In traditional diaphragm coating processes, the coating of diaphragm
Majority is coated using gravure roll, but when use gravure roll application, because slurry is placed in the outer surface of gravure roll, is easy to make to starch
Material is fallen on diaphragm, is caused the coating thickness of diaphragm uneven, is also increased the usage amount of slurry, improve material cost.
Summary of the invention
In view of the above-mentioned defects in the prior art, the present invention provides a kind of diaphragm for lithium ion battery coating unit, structure letter
Single, easy to operate, coating efficiency is high, reduces material cost.
To achieve the above object, the technical scheme adopted by the invention is that:
A kind of diaphragm for lithium ion battery coating unit, including roller, the roller include hose and setting on a hose left side
The connector at right both ends is equipped with the storage chamber for storing slurry in the hose, several mesh, institute is distributed on the hose
State the scraper being equipped in hose for squeezing out the slurry in storage chamber outward from mesh.
In above description, preferably, further including the photoresists for occluding member mesh.
In above description, preferably, at least one described connector is equipped with transmission gear.
In above description, preferably, at least one described connector is equipped with feeding-passage, the feeding-passage and institute
State storage chamber connection.
In above description, preferably, further including mounting base, the mounting base is equipped with the installation for installing scraper
Frame.
In above description, preferably, the diameter of the mesh is 0.25mm~0.5mm.
In above description, preferably, coverage rate of the mesh on hose is 7%~30%.
In above description, preferably, center between the two neighboring mesh is away from for 0.5mm~2mm.
In above description, preferably, the hose is made of metal foil curling welding.
In above description, preferably, the metal soft board with a thickness of 30~100um.
The working principle of the invention, in use, photoresists are sealed in the full coat according to required for diaphragm or pattern coating, selection
It blocks up a part of mesh or directly carves out required pattern on metal foil, the slurry of coating is logical by the charging on connector
Road enters in hose, and transmission gear is connected to motor, and hose is driven to rotate, and scraper uniformly scrapes the slurry in hose to net
Hole, slurry are attached on diaphragm by mesh, complete coating.
The invention has the advantages that: several mesh are distributed on metal hose, is equipped with scraper in hose, passes through
The scraper of inside hose squeezes out slurry outward from mesh, completes coating, and coating method is more advanced, and slurry coating is more equal
It is even；By the way that photoresists are arranged, occluding member mesh, may be implemented the coating effect of the different pattern of diaphragm according to demand, reduce
Material cost.
More clearly to illustrate structure feature of the invention, technological means and its specific purposes achieved and function, under
In conjunction with attached drawing and specific embodiment, invention is further described in detail in face:
