Abstract
A kind of liquid storage bottle laser seal method.Using a CO2Laser-beam welding machine is in glove box, and using argon gas as protective gas, laser seal is carried out to liquid storage bottle.Laser welding program has been worked out, has formulated that thionyl chloride solution is filling, the operating procedure of liquid storage bottle closure.This method has that effect is good, and qualification rate is high, free of contamination feature.Liquid storage bottle laser seal method of the present invention preferably meets the technical requirements of small size liquid storage bottle.
Description
Technical field
The invention belongs to Small-Caliber Ammunition Fuze Technology field, more particularly to a kind of reserve type lithium battery liquid storage bottle laser envelope
Mouth method.
Background technology
Currently, ammunition fuze field is developed towards electronic direction, and electronic fuse needs the energy, therefore just must be equipped with to draw
Believe the power supply of power supply, i.e. fuze power supply.Lithium-thionyl chloride battery is a kind of typical non-aqueous electrodeless electrolyte solution power supply, is had
Standby small volume, in light weight, low temperature performance well higher than energy, the characteristics of power-on time is long, be Small-Caliber Ammunition preferable fuse electricity
Source.As reserve type battery, generally thionyl chloride solution is sealed in liquid storage bottle, isolated with lithium.Need to break during galvanic action
Liquid storage bottle is opened, thionyl chloride is contacted with lithium, produces chemical reaction, generates electric current.Thionyl chloride solution low boiling point (70~80
DEG C), high volatility, chance water electrode, which easily reacts, generates sulfuric acid and hydrochloric acid, and corrosivity is strong, and generally use vial carries as liquid storage
Body.The sealing of vial is the minor diameter bottleneck by being heated at high temperature vial, makes what the glass melting of bottleneck was realized together.
Now welded frequently with acetylene flame, acetylene flame welding liquid storage bottle has the disadvantage that：1st, the region of heating is larger, and welding temperature is low, glass
Glass fusing time is grown, and the easily heated volatilization of thionyl chloride solution and water vapor in air reaction are rotten；2nd, in order to avoid thionyl chloride
The heated volatilization of solution, go bad, heating zone causes the liquid storage bottle height after sealing higher away from thionyl chloride solution is needed.And osculum
Small volume of footpath ammunition fuze itself, inner components quantity up to dozens of, liquid storage bottle is also one of Fuze Components, and this will
Ask the volume of liquid storage bottle the smaller the better.Traditional flame sealing technology, small size liquid storage bottle technical requirements are not reached.
The content of the invention
The purpose of the present invention is exactly to overcome the shortcomings of above-mentioned background technology, proposes a kind of reserve type lithium battery liquid storage bottle
Laser seal method.
A kind of reserve type lithium battery liquid storage bottle laser seal method involved in the present invention, it is comprised the following steps that：
1) CO is opened2Laser-beam welding machine general supply, " driving " key on pressing operation panel, connect cooling system, laser
The power switches such as device, rotation gas cylinder valve connect argon gas, and the time is about 5 minutes；
2) " jerk " switch is discharged, after the completion for the treatment of PLC control system self-test, laser is opened, presses " correction " key, use feux rouges
" rising ", " decline " button are by focus lamp and workpiece to good；
3) water content in latex examination gloves case, if water content is not up to standard, is cleaned to casing；
4) thionyl chloride solution, liquid storage bottle, syringe, tweezers, medical rubber glove, the paper of bottle sealing will be distributed into
Towel etc. is successively put into glove box by glove box transfer chamber；
5) reaffirm whether the water content in glove box is up to standard, then thionyl chloride solution is injected by syringe and stored up
Liquid bottle, 0.15~0.2ml of injection volume, and the electrolyte of spilling is sucked with paper handkerchief, it is placed on after syringe use on paper handkerchief；
6) liquid storage bottle after splendid attire is placed on workbench special tooling according to the laser welding program of setting and carries out trying to add
Laser current is adjusted for work, sealing quality visually, and the sealing of remaining liquid storage bottle is completed after steady quality；
7) after sealing, by the liquid storage bottle sealed, used syringe, thionyl chloride solution empty bottle, paper handkerchief etc.
Successively taken out by glove box transfer chamber；
8) " driving " key is closed, presses rapid stop key, disconnects the power supplys such as cooling system, laser, closes air door, is disconnected
CO2Laser-beam welding machine general supply；
9) liquid storage bottle for having sealed completion is immersed in hot water, hot water temperature is 80~90 DEG C, observes the sulfurous of its storage
Whether solution of acid chloride reacts with water, takes out the liquid storage bottle not reacted after 5~10 minutes, is used after being dried with paper handkerchief
PH test paper is detected.Certified products, which are put into special container, to be put neatly.
The reserve type lithium battery liquid storage bottle laser seal method of the present invention, highly low, liquid storage bottle closure after liquid storage bottle closure
Qualification rate is high, pollution-free, and the thionyl chloride solution of storage can meet small size liquid storage bottle technical requirements without going bad in liquid storage bottle.
