Description
Technical field
The utility model relates to technical field of lithium batteries more particularly to a kind of lithium battery to produce atmospheric pressure testing auxiliary device.
Background technique
Lithium battery lays in medium as the emerging energy occurred a kind of the 1990s, big, defeated by its energy density
It is many excellent that power height, charge discharge life length, quickly-chargeable, green non-pollution, operating temperature range are wide out and self discharge is small etc.
Point is just receiving more and more attention, and to solving, human environment pollutes and energy crisis has great significance.
Whether, in the preparation link of lithium ion battery, chemical system, process flow are improved day by day, and may be used as verifying battery
Also gradually to means of testing requirement, more abundant, test accuracy requires higher, testing process to want to a series of test macros leaned on
It asks and more efficiently directions is waited to develop.
In battery detecting project, it is an extremely crucial index that inside, which produces atmospheric pressure, inside battery produce atmospheric pressure compared with
Height cause battery shell wall bulging, explosion-proof valve open the fault modes such as leakage by directly affect entire battery system performance,
Reliability and safety, therefore the detection device for designing its reliability has become inevitable requirement.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of production atmospheric pressure test of lithium battery is auxiliary
Device is helped, effect is good.
The utility model proposes a kind of lithium battery produce atmospheric pressure testing auxiliary device, including backing plate, pressing plate, pressing plate and pad
The removable connection of plate, pressing plate are equipped with boss close to the side of backing plate, form machining area between the boss and backing plate；On pressing plate also
Equipped with mounting hole, surface of the pressing plate far from backing plate is run through in one end of the mounting hole, and the other end of mounting hole is through boss close to pad
The surface of plate.
Preferably, pressing plate is bolted with backing plate.
Preferably, mounting hole is threaded hole.
Preferably, sealing ring is installed on boss.
In the utility model, when operation, battery is first placed in backing plate middle position, then external pressure survey will have been had connected
The pressing plate that trial assembly is set is aligned with backing plate to be bonded, and during fitting, boss bursting battery anti-explosion valve realizes connection, is arranged
Sealing ring is embedded in battery anti-explosion valve inner ring；Then bolt is tightened, keeps the outer ring of sealing ring and the inner ring of battery anti-explosion valve close
Fitting, play the role of it is air current sealed, to realize the fixation to battery, connection and sealing.
The utility model is not implemented only in and is fixed to battery, can also realize connection with inside battery and with
The sealing of external pressure measuring device；Promote testing efficiency, test accuracy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutual combination；Below with reference to the accompanying drawings it and in conjunction with the embodiments elaborates to the utility model.
Referring to Fig.1, the utility model proposes a kind of lithium battery produce atmospheric pressure testing auxiliary device, including backing plate 1, pressing plate
2, pressing plate 2 and the removable connection of backing plate 1, pressing plate are equipped with boss 3 close to the side of backing plate, are formed and are added between the boss 3 and backing plate
Work area domain；Mounting hole is additionally provided on pressing plate, surface of the pressing plate far from backing plate is run through in one end of the mounting hole, mounting hole 4 it is another
End is through boss close to the surface of backing plate.
In further embodiment, pressing plate is connect with backing plate by bolt 5.Using being bolted pressing plate, backing plate.
In further embodiment, mounting hole 4 is threaded hole.Facilitate installation.External pressure test device and mounting hole
Connection.
Sealing ring 6 is installed in further embodiment, on boss.Improve leakproofness.
When operation, battery is first placed in backing plate middle position, then the pressing plate that will have connected external pressure test device
It is aligned and is bonded with backing plate, during fitting, boss bursting battery anti-explosion valve realizes connection, the sealing ring insertion electricity being arranged
In the explosion-proof valve inner ring of pond；Then bolt is tightened, the outer ring of sealing ring and the inner ring of battery anti-explosion valve is fitted closely, plays air-flow
Sealing function, to realize the fixation to battery, connection and sealing.
The present embodiment is not implemented only in and is fixed to battery, can also realize connection with inside battery and with it is outer
The sealing of portion's device for pressure measurement；Promote testing efficiency, test accuracy.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
