Electrode plates is the important component part of lithium ion battery, is very important link in the lithium ion battery production run, is the core of lithium ion battery.The quality problems such as the quality that applies out pole piece determines the performance of lithium ion battery, and is high such as self discharge, that cycle life is short, storage time is short, voltage is low.The burner hearth oven dry is the important component part that lithium battery is produced, and the quality of burner hearth oven dry will directly have influence on quality and the progress of coating pole piece, and then the performance of lithium battery is affected.Easily produce NMP, chemicals Chinese 1-METHYLPYRROLIDONE, chemicals English name N-methyl-2-pyrrolidone in actual production, key property: colourless transparent liquid, 202 ℃ of boiling points, 95 ℃ of flash-points can be miscible with water, be dissolved in ether, acetone and various organic solvent slightly have the ammonia flavor, stable chemical performance, carbon steel, aluminium are not corroded, copper slightly is corrosive.Main Ingredients and Appearance is benzene aromatic hydrocarbon class material, has the smell as banana, mainly as thinning agent, meet heat, meet the blast of naked light easy firing, can with oxygenant generation vigorous reaction, its steam is heavier than air, and can be diffused in the lower place quite far away, fire occurs to meet strile-back.Thereby the concentration of NMP in burner hearth both affected the quality of coating, existed again safety problem.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of coating machine NMP concentration autoalarm is provided, and detects the NMP value in burner hearth and points out warning, guarantees production safety.
The utility model for achieving the above object, by the following technical solutions: a kind of coating machine NMP concentration autoalarm is characterized in that: comprising:
Gas sensor for detection of the concentration of outside NMP, and is transferred to control module with the NMP concentration value that detects by the A/D change-over circuit;
Control module is used for receiving the NMP concentration value and compares with the NMP concentration value of presetting, if send alerting signal to alarm module greater than default NMP concentration value;
Alarm module is used for receiving the alerting signal that control module is sent, and carries out alarm.
Also comprise display module, be connected with control module, be used for showing the concentration value of NMP.
Described gas sensor adopts the MQ5 gas sensor.
Described control module adopts AT89LV51 low-voltage single-chip microcomputer.
Described display module is adopted the dm12232fLED display.
Described alarm module adopts hummer or/and light emitting diode.
The beneficial effects of the utility model are: the utility model is simple in structure, and can complete reports to the police to NMP concentration controls automatically, and easy to carry, and finished product can be embedded in burner hearth inside very easily, and design cost is cheap.The part that software section only need be changed seldom just can realize other function, makes systemic-function more perfect.A/D converter adopts 11 passages, can expand.
