Description
Technical field
The present invention relates to lithium battery pole piece coating technical field more particularly to a kind of novel closed-type coater ovens.
Background technology
Coating process is all can't do without in the manufacture of mainstream lithium battery currently on the market, and pole coating quality directly affects battery
Overall performance, be process mostly important in Production Process of Lithium Battery.It is needed after pole coating by drying link, coating
Pole piece after slurry often will appear the situation of dropping off in baking oven baking process, and the powder fallen is accumulated in an oven, easily for a long time
The blocking in each air duct is caused, leads to the reduction of wind speed and the efficiency of heating surface, while the dust in baking oven seriously affects coating pole piece
Quality.

Powder be difficult to clean off, and detachable panel type baking oven in pole piece baking process can not continue cleaning powder, can only be in baking oven
It is cleared up after being stopped.The Chinese patent of patent No. 201010105177.X discloses a kind of detachable panel type coating machine
Baking oven, including babinet theme, side panel, operation door, gasket, fastening bolt, it is characterised in that baking oven after a shutdown, can be opened
The side panel of baking oven, so as to clear up the dust of oven interior, after for clearance, loading onto side panel can just produce, though it should
Baking oven can clear up powder to a certain extent, but there are more defects, such as：(1) side panel is simply installed at the side of baking oven,
Compared with easy to clean, the opposite side far from side is difficult to clear up dust close to side panel side due to oven interior narrow space；
(2) cleaning of baking oven has to after a shutdown, also needs to wait for oven temperature and drops to artificial operable temperature, higher temperature is easily made
It is scalded into worker, larger security risk is brought to cleaning；(3) coater oven needs personnel's timing to shut down cleaning, long
Downtime so that production efficiency is low, while also increases the labor intensity of worker.
In conclusion it is badly in need of a kind of equipment that can clear up dust in coater oven the moment at present, so as to improve pole piece
Baking quality, while nor affect on production efficiency.
