Abstract
The utility model discloses a cylindrical lithium -ion battery closing device, including the box hat, and be used for the positioning fixture that the box hat sealed, this closing device still include with the negative pressure cavity that positioning fixture top seal set up, and run through the negative pressure cavity seal the mould, seal the mould with the negative pressure cavity slides and sets up. With this structural design, can be through the setting of negative pressure cavity for with the inside negative pressure that forms of negative pressure cavity matched with box hat casing, under this state, the rethread seals the mould and seals the box hat.
Description
Technical field
This utility model is related to technical field of lithium ion, more particularly, to a kind of cylindrical lithium ion battery sealing dress
Put.
Background technology
Sealing device used in cylindrical steel shell battery production technology, makes battery seal operation in normal atmosphere (An) at present
Carry out under the dry gas of (normal atmosphere).There is normal ambient pressure in the box hat inside battery after sealing.
After battery charging and discharging, due to factors such as internal structure and electrolyte, in being recycled for a long time, inside battery is anti-
Should, lead to cylindrical steel shell inside battery to produce substantial amounts of gas, make box hat modification, or even destroy battery.
Utility model content
The purpose of this utility model is to provide a kind of is easy to the cylindrical lithium ion cell in subnormal ambient lower sealing for the box hat
Pond closing device.
For reaching this purpose, this utility model employs the following technical solutions：
A kind of cylindrical lithium ion battery closing device, including box hat, and the positioning fixture for described box hat sealing,
This closing device also includes the negative pressure cavity with the sealing setting of described positioning fixture top, and the sealing running through described negative pressure cavity
Mould, described seal mould is slided with described negative pressure cavity and arranges.
Wherein, the bottom surface of described negative pressure cavity is provided with sealing gasket, the upper surface of described sealing gasket and described positioning fixture
Fit.
Wherein, on the cavity wall of described negative pressure cavity, insertion is provided with pressure port, and described pressure port is connected with external pressure pump
Connect.
Wherein, the top of described negative pressure cavity is axially provided through through hole, and the two side of described through hole is provided with sealing
Circle, described sealing ring is matched with the mould post of described seal mould.
Wherein, described negative pressure cavity and described seal mould are connected with outside first drive mechanism and the second drive mechanism respectively
Connect.
The beneficial effects of the utility model：This utility model includes box hat, and the locating clip for described box hat sealing
Tool, this closing device also includes the negative pressure cavity with the sealing setting of described positioning fixture top, and the envelope running through described negative pressure cavity
Mouth mould, described seal mould is slided with described negative pressure cavity and arranges.With this structure design, the setting of vacuum cavity can be passed through so that
The box hat enclosure interior matching with negative pressure cavity forms negative pressure, in this case, then by seal mould, box hat is sealed.
Brief description
Fig. 1 is a kind of structural representation of this utility model cylindrical lithium ion battery closing device.
Specific embodiment
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by specific embodiment.
As shown in figure 1, a kind of cylindrical lithium ion battery closing device in the present embodiment, including box hat 1, and it is used for institute
State the positioning fixture 2 of box hat 1 sealing, this closing device also includes the negative pressure cavity 3 with the sealing setting of described positioning fixture 2 top,
And run through seal mould 4, described seal mould 4 and the described negative pressure cavity 3 slip setting of described negative pressure cavity 3.
Specifically, in the present embodiment, the bottom surface of described negative pressure cavity 3 is provided with sealing gasket 5, described sealing gasket 5 with described
The upper surface of positioning fixture 2 fits, and insertion on the cavity wall of described negative pressure cavity 3 is provided with pressure port 31, described pressure port 31
It is connected with external pressure pump,
In the present embodiment, for the ease of sealing, and seal mould with respect to negative pressure cavity can in motor process will not gas leakage,
The top of described negative pressure cavity 3 is axially provided through through hole, and the two side of described through hole is provided with sealing ring 6, described sealing
Circle 6 is matched with the mould post of described seal mould 4.
Specifically, described negative pressure cavity 3 and described seal mould 4 respectively with outside first drive mechanism and the second drive mechanism phase
Connect.In operation, the first drive mechanism can be first passed through so that forming a seal cavity between negative pressure cavity and positioning fixture,
Pass through the second drive mechanism afterwards again and drive seal mould work, complete the sealing of lithium battery.
Describe know-why of the present utility model above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the restriction to this utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art does not need to pay performing creative labour and can associate other specific embodiment of the present utility model,
These modes fall within protection domain of the present utility model.
