Abstract

The utility model relates to an automatic feeding system, in particular to a novel automatic feeding system for coating of a lithium battery. The novel automatic feeding system for the coating of the lithium battery is characterized by comprising a pressurization system, a slurry barrel with a stirring function, a pipeline and a valve. The pressurization system comprises a nitrogen gas cylinder and an air inflow and pressure release valve. A barrel cover is arranged on the top of the slurry barrel with the stirring function. A stirring system and the air inflow and pressure release valve are arranged on the barrel cover. A slurry barrel valve is disposed on one side of the bottom of the slurry barrel with the stirring function and connected with a discharge port valve through the pipeline. According to the novel automatic feeding system for the coating of the lithium battery, air pressure is utilized to press slurry into a trough on a head portion of a coating machine, and then automatic feeding work is finished. Besides, a diaphragm pump is not needed, flow velocity of the slurry at the time of discharging is constant without large fluctuations, and therefore the liquid level of the slurry in the trough on the head portion of the coating machine is ensured to be stable, and a pass rate of density of a coated pole piece surface can be improved. Moreover, the problem that the slurry contacts with moisture in the air can be solved effectively so that the quality problem caused by water absorption of the slurry is avoided.

Description

Automatical feeding system is used in a kind of novel lithium battery coating
Technical field
The utility model relates to a kind of automatical feeding system, is specially a kind of novel lithium battery coating and uses automatical feeding system.
Background technology
In the lithium battery production process; Generally be that slurry to be coated is loaded in the slurry bucket; Adopt manual mode the slurry for preparing to be joined in the hopper at coater head place with spoon; When adopting this kind mode, the appearance lamination that the slurry in the slurry bucket will be slowly, pole piece surface density fluctuation when causing being coated with.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model is to provide the technical scheme of a kind of novel lithium battery coating with automatical feeding system.
Automatical feeding system is used in described a kind of novel lithium battery coating; It is characterized in that forming by slurry bucket, pipeline and valve that compression system, band stir; Compression system comprises nitrogen cylinder and air inlet and relief valve, and the slurry bucket top that band stirs is provided with bung, and stirring system and air inlet and relief valve are set on the bung; Slurry bucket bottom one side that band stirs is provided with slurry bucket valve, and slurry bucket valve links to each other with the discharging opening valve through pipeline.
Automatical feeding system is used in described a kind of novel lithium battery coating, it is characterized in that described nitrogen cylinder connects air inlet and relief valve through pipeline.
Automatical feeding system is used in described a kind of novel lithium battery coating, it is characterized in that described discharging opening valve matches with the head hopper of coating machine.
The utility model is made up of slurry bucket, pipeline, valve that compression system, band stir, utilizes air pressure that slurry is depressed into the head hopper place of coating machine, and then accomplishes automatic charging work.Slurry bucket top is provided with the bung of a band stirring system, and air inlet and relief valve are arranged on the bung, and after slurry added the slurry bucket, the bung and fixing of closing made bucket sealing fully; Open nitrogen pressure, pressure gets final product at 0.02MPa, opens the discharging opening valve at coating machine head hopper place and adjusts valve size according to the speed of coating, guarantees slurry and coating speed basically identical.Native system need not membrane pump, and constant flow rate does not have big fluctuation during the slurry discharging, thereby has guaranteed the slurry level stability in the coater head place hopper, so the pole piece surface density qualification rate of coating will improve.And efficiently solve contacting of moisture content in slurry and the atmosphere, thereby the quality problems of having avoided the slurry suction to cause.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-nitrogen cylinder; 2-air inlet and relief valve; The 3-stirring system; The 4-bung; The slurry bucket that the 5-band stirs; 6-slurry bucket valve; The 7-pipeline; 8-discharging opening valve.
The specific embodiment
Below in conjunction with Figure of description the utility model is further specified:
Automatical feeding system is used in a kind of novel lithium battery coating; Slurry bucket, pipeline and valve by compression system, band stir are formed, and compression system comprises nitrogen cylinder 1 and air inlet and relief valve 2, and slurry bucket 5 tops that band stirs are provided with bung 4; Stirring system 3 and air inlet and relief valve 2 are set on the bung 4; Nitrogen cylinder 1 connects air inlet and relief valve 2 through pipeline, the slurry that band stirs, and 5 bottoms, one side is provided with slurry bucket valve 6; Slurry bucket valve 6 links to each other with discharging opening valve 8 through pipeline 7, and discharging opening valve 8 matches with the head hopper of coating machine.
The utility model utilizes air pressure that slurry is depressed into the head hopper place of coating machine, and then accomplishes automatic charging work.Slurry bucket top is provided with the bung of a band stirring system, and air inlet and relief valve are arranged on the bung, and after slurry added the slurry bucket, the bung and fixing of closing made bucket sealing fully; Open nitrogen pressure, pressure gets final product at 0.02MPa, opens the discharging opening valve at coating machine head hopper place and adjusts valve size according to the speed of coating, guarantees slurry and coating speed basically identical.
Native system need not membrane pump, and constant flow rate does not have big fluctuation during the slurry discharging, thereby has guaranteed the slurry level stability in the coater head place hopper, so the pole piece surface density qualification rate of coating will improve.
