Summary of the invention
This novel purpose be exactly provide a kind of at the deficiencies in the prior art part and can produce automatically continuously, apply evenly, yield rate is high, and can detect the coating drying unit of the lithium ion battery of qualified products automatically.
For achieving the above object, this novel technical scheme is: a kind of coating drying unit of lithium ion battery, include unreeling structure, applying mechanism, scraping mechanism, baking mechanism and rolling-up mechanism, unreeling structure mainly is made up of let off roll and the coating that is wrapped on the let off roll, and the coating on the let off roll transmits and is connected to applying mechanism; Applying mechanism mainly is made up of the symmetrically arranged liquid electrode material feed opening of going up application roll and following application roll and being positioned at above the application roll up and down, applying mechanism is positioned at the oblique upper of scraping mechanism, is coated with by tilting to transmit to be connected to mobile being distributed in the coating of liquid electrode material in the feasible coating of scraping mechanism between last application roll and the following application roll; Scraping mechanism is made up of at least one pair of symmetrically arranged up and down upward scraper roller and following scraper roller, and the gap between last scraper roller and the following scraper roller is corresponding with the standard thickness that setting has the coating of liquid electrode material, and coating is transmitted by the gap between last scraper roller and the following scraper roller and is connected to baking mechanism; Baking mechanism is mainly formed by plurality of sections baking box serial connection, and coating is sent to wind-up roll rolling in the rolling-up mechanism by toasting in-house several flat idlers.
Between described baking mechanism and rolling-up mechanism, also be provided with and detect mark mechanism, detect that mark mechanism includes the detector that is used for detecting baking back coating thickness and according to the mark device of testing result sign acceptance or rejection product labelling.
Described surface of going up scraper roller and following scraper roller is a smooth surface.
The length of described liquid electrode material feed opening is corresponding with the length of last application roll.
Described liquid electrode material feed opening is connected by pump with pay-off.
After adopting said structure, this is novel to make the liquid electrode material in the coating be distributed in the coating in deadweight effect current downflow by making applying mechanism be positioned at the oblique upper of scraping mechanism, avoid being coated with coating less than the room; Define coating by scraping mechanism by symmetrically arranged gap of going up between scraper roller and the following scraper roller up and down again and it goes up the thickness of liquid electrode material, after toasting by baking mechanism at last by the rolling-up mechanism rolling.In addition, detect mark mechanism and detect baking back coating thickness, and according to testing result sign acceptance or rejection product labelling.Hence one can see that, this is novel have can produce automatically continuously, apply evenly, yield rate is high, and can detect the characteristics of qualified products automatically.
