Description
Technical field
The utility model relates to a kind of lithium battery production ancillary equipment more particularly to a kind of lithium battery negative pressure cup devices.
Background technique
It by lithium metal or lithium alloy is negative electrode material, using the battery of non-aqueous electrolytic solution that lithium battery ", which is a kind of,.
Lithium metal battery in 1912 is proposed and is studied by Gilbert N. Lewis earliest.Since the chemical characteristic of lithium metal is very living
It sprinkles, so that the processing of lithium metal, preservation, use, very high to environmental requirement.So lithium battery is not applied for a long time.With
The development of science and technology, present lithium battery has become mainstream.Negative pressure cup device used at present made in battery
The disadvantages of electrolyte waste is more serious in journey, and attended operation is complicated, and leakproofness is poor.
Utility model content
The purpose of this utility model is to provide a kind of lithium battery negative pressure cup devices, to solve the above technical problems.
To achieve the above object the utility model use following technical scheme: including upper cover, big rubber ring, cup body, soup stick,
Small sealing ring, guide sleeve, spring, suction nozzle, the big rubber ring are embedded in upper cover inside edge position, and upper cover is threadedly coupled with cup body,
The small sealing ring is sleeved on the thread spindle on soup stick top, and is threadedly coupled with cup base, and the guide sleeve and spring are successively
It covers and is loaded on the outside of soup stick from soup stick bottom end, and fixed using E type circlip, the suction nozzle is threadedly coupled with soup stick bottom end.
On that basis of the above technical scheme, the upper cover, cup body, soup stick, guide sleeve and suction nozzle use corrosion-resistant PC material
Production.
On that basis of the above technical scheme, the upper cover and cup body are die sinking production, and wherein cup body is transparent cup body.
On that basis of the above technical scheme, the utility model is directly directly connected to at the screw thread of upper cover using nut, this
Cup body leakproofness can be improved in the advantages of sample way, and for cup body volume up to 80ml, vacuum degree reaches 97.5 ~ 100KPa, leak rate
0.3KP/ minutes, it can reach professional standard.
Compared with prior art, the utility model has the advantage that negative pressure cup device designed by the utility model, solution
Hard shell lithium battery determined in negative pressure chemical synthesis technology, has saved electrolyte of battery during processing procedure, convenient for safeguarding, leakproofness is good
Good, vacuum degree and leak rate are up to professional standard.
Detailed description of the invention
Fig. 1 is the main view of the utility model.
Fig. 2 is the sectional view of the utility model.
Fig. 3 is the assembling schematic diagram of the utility model.
Fig. 4 is that the upper cover of the utility model connect diagrammatic cross-section with cup body.
In figure: upper cover 1, big rubber ring 2, cup body 3, soup stick 4, small sealing ring 5, guide sleeve 6, spring 7, suction nozzle 8.
Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, including upper cover 1, big rubber ring 2, cup body 3, soup stick 4, small sealing ring 5, guide sleeve
6, spring 7, suction nozzle 8, the big rubber ring 2 are embedded in 1 inside edge position of upper cover, and upper cover 1 is threadedly coupled with cup body 3, described small
Sealing ring 5 is sleeved on the thread spindle on 4 top of soup stick, and is threadedly coupled with 3 bottom end of cup body, the guide sleeve 6 and spring 7 successively from
4 bottom end of soup stick set loads 4 outside of soup stick, and is fixed using E type circlip, and the suction nozzle 8 is threadedly coupled with 4 bottom end of soup stick.
The present invention relates to the die sinking special negative pressure cup assembly practicability of negative pressure cup device, this negative pressure cup assembly passes through fixation
On negative pressure mould group, realizes and negative pressure formation process is carried out to this battery of negative pressure cup device, so as to realize lithium battery just
Pole and cathode form SEI film, and can finally charge, and form the battery of our needs, this process is exactly the chemical conversion of lithium battery
Technique, and the special negative pressure cup assembly being opened just is applied to above this chemical synthesis technology.The utility model negative pressure cup device is
Injection molding forms product after being opened, and the function of this vacuum cup: makes hard shell lithium battery when doing negative pressure formation process, in battery
Air is released, and while vacuumizing, the electrolyte of inside battery can be released, this vacuum cup main purpose is easy for
Part electrolyte is stored under the action of micro-positive pressure, to return in inside battery, prevent electrolyte after the completion of negative pressure chemical conversion
After inside battery electrolyte is pumped, reservoir quantity is inadequate in battery, causes battery defective products.The utility model is direct using nut
It is directly connected to at the screw thread of upper cover, the advantages of such way, cup body leakproofness can be improved, cup body volume is up to 80ml, very
Reciprocal of duty cycle reaches 97.5 ~ 100KPa, and leak rate 0.3KP/ minutes, vacuum degree and leak rate can reach professional standard, has saved battery and has made
Electrolyte during journey.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired
Change, replacement and variant is still fallen within the protection scope of the utility model.
