The mode (connection parallel with lug 6 of stem 2, such as Fig. 2) of welding, after battery core 5 enters shell, lid group plane is completely covered by box hat mouth
Portion is not carried out the operating space of quantitative liquid-filling, can only use vacuum by the liquid injection hole 4 in lid group after having welded lid group
The mode of suck-back carries out excessive fluid injection, it is difficult to realize accurate quantitative liquid-filling, on the one hand cause the waste of electrolyte in this way, separately
The outer consistency control for being also unfavorable for battery performance, and also need to carry out compressed steel pearl sealing after having noted liquid, more procedures
Also increase a leakage hidden danger point simultaneously.Lid group designed by this patent can solve the problems, such as it is above-mentioned these, by special
Lid group structure design improves the sequence of operation and mode of operation, reduces the risk that battery forms micro-short circuit in lid group welding process, just
In realization quantitative liquid-filling, and eliminate compressed steel pearl process so that battery life is effectively reduced while battery with two side terminals is promoted
Cost is produced, the sealing reliability of battery is promoted.
Utility model content
The purpose of this utility model is to overcome the shortcomings of background technology, and provide a kind of hermetically sealed lithium battery cap
Group structure.
To achieve the goals above, the technical solution of the utility model is：Hermetically sealed lithium battery cap group structure, including lid
Plate, stem, glass insulator, battery core and lug, it is characterised in that：The stem is made of cylinder and column plate, and cylinder upper end is logical
It crosses glass insulator to connect with cover board, cylinder lower end and column plate vertical connection, the cover board are positioned over horizontal by angle
Battery core top edges position, the lug lower end are located in battery core, and lug upper end is connect using spot welding with column plate.
In the above-mentioned technical solutions, the cross section of the column plate is round, perpendicular arrangement between the lug and cylinder,
And in parallel arrangement between lug and column plate.
Compared with prior art, the beneficial effects of the utility model are as follows：
(1) change lid group spot welding mode, reduce damage of the spot welding spark to battery diaphragm, reduce the several of battery internal short-circuit
Rate；
(2) quantitative liquid-filling for realizing hermetically sealed lithium battery, on the one hand promotes battery with two side terminals, in addition reduces electrolyte
Loss；
(3) operation for cancelling compressed steel pearl, saves cost of labor, reduces the hidden danger of battery leakage, and it is reliable to promote cell sealing
Property.

Specific implementation mode
The performance that according to the present invention will be described in detail below with reference to the accompanying drawings, but they are not constituted to the utility model
It limits, it is only for example.The advantages of making the utility model by explanation simultaneously, is more clear and is readily appreciated that.
Refering to known to attached drawing：Hermetically sealed lithium battery cap group structure, including cover board 1, stem 2, glass insulator 3,5 and of battery core
Lug 6, it is characterised in that：The stem 2 is made of cylinder 7 and column plate 8, and 7 upper end of cylinder passes through glass insulator 3 and cover board 1
Connection, 7 lower end of cylinder and 8 vertical connection of column plate, the cover board 1 are positioned over 5 top edges position of battery core horizontal by angle
It sets, 6 lower end of the lug is located in battery core 5, and 6 upper end of lug is connect using spot welding with column plate 8.
Preferably, the cross section of the column plate 8 is circle, perpendicular arrangement between the lug 6 and cylinder 7, and lug 6
In parallel arrangement between column plate 8.
The present invention is the positive cover group of hermetically sealed lithium battery, positive leading-out terminal of 2 upper end of stem as battery, cover board 1
By the sealing with the complete battery pair of the laser welding of battery case, glass insulator 3 plays connecting cover plate 1 and stem 2 while again
The effect of insulation.The present invention is effectively increased the spot welding area of 2 end face of stem by the way that 2 lower end of stem is designed to the header structure of falling T,
It is easy to implement the spot weld operation of lug 6 and 2 end face of stem, to change spot welding direction (lug 6 and lid group of the stem 2 with lug 6
Stem 2 is in 90 ° of welding, such as Fig. 4), operating space is vacateed in specified rate fluid injection.When quantitative liquid-filling can pass through open battery faucal
After portion realizes, the excessive fluid injection mode of suck-back need not be just used, then also there is no need to reserve liquid injection hole 4, note on cover board
Vacuum standing is carried out after the completion of liquid, is accelerated the absorption of electrolyte, the 90 ° of overturnings of lid group is then subjected to lid group pressing, then carry out close
Soldering and sealing connects, and completes assembly.
Other unaccounted parts belong to the prior art.
