Abstract
The utility model is related to a kind of lithium battery process units, specially lithium battery aluminum-plastic film closing device, including vacuumizes casing, and descending cylinder is arranged on the upper surface of upper cover base, the lower surface connection upper cover of upper cover base；Described low head is arranged on low head base upper surface, and the lower surface of low head base installs promoting the circulation of qi cylinder；Described upper cover, the end face of low head have the ripple being mutually matched；Casing is vacuumized to be connected with evacuator by vacuum tube, and by floor push control.The lithium battery aluminum-plastic film closing device that the utility model is provided, increase the contact area of end socket, when being engaged above and below end socket, the copper end socket of heating makes the PP layers of two layers of aluminum plastic film carry out welding and forms sealing state by temperature and pressure, effectively prevents lug leakage, Teflon need not be pasted, remove the time of patch Teflon from, improve production efficiency, save the cost of Teflon, temperature can be reduced, and save electric cost.
Description
Technical field
The utility model is related to a kind of lithium battery process units, specially lithium battery aluminum-plastic film closing device.
Background technology
The end socket that existing lithium battery aluminum-plastic film sealing is used is copper end socket, and end socket upper end is plane, is being sealed
One layer of Teflon need to be pasted during mouth.The shortcoming of the end socket has：
1st, Teflon is easily damaged, it is necessary to a Teflon is changed per 1H, and is operated in glove box, very not square
Just, therefore production efficiency is largely effected on；
2nd, end socket needs to paste Teflon, therefore end socket temperature needs increase by 20 degree (190 DEG C) just to make the surface of Teflon
Temperature reaches technological requirement, therefore temperature is higher, and power consumption is bigger；
3rd, end socket needs to paste Teflon, and the material cost of Teflon is more；
4th, end socket upper end is plane, in the case of aluminum plastic film has and crumpled, and sealing is easy for leakage.
Utility model content
For above-mentioned technical problem, a kind of cost of the utility model offer is low, not easy-to-leak liquid lithium battery aluminum-plastic film sealing
Device.
Specifically technical scheme is：
Lithium battery aluminum-plastic film closing device, including casing is vacuumized, described vacuumizing in casing is wrapped successively from top to bottom
Include descending cylinder, upper cover base, upper cover, low head, low head base and up cylinder；Described descending cylinder is arranged on
The upper surface of upper cover base, the lower surface connection upper cover of upper cover base；Described low head is arranged on low head base
Upper surface, the lower surface of low head base installs promoting the circulation of qi cylinder；Described upper cover, the end face of low head have the ripple being mutually matched
Line；Casing is vacuumized to be connected with evacuator by vacuum tube, and by floor push control.
Described descending cylinder, up cylinder are arranged on upper cover base, on low head base by limited screw respectively.
The lithium battery aluminum-plastic film closing device that the utility model is provided, increases the contact area of end socket, is stung above and below end socket
During conjunction, the copper end socket of heating makes the PP layers of two layers of aluminum plastic film carry out welding and forms sealing state by temperature and pressure, effectively
Prevent lug leakage, it is not necessary to paste Teflon, remove from patch Teflon time, improve production efficiency, save Teflon into
This, temperature can be reduced, and save electric cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described with reference to the drawings.
As shown in figure 1, lithium battery aluminum-plastic film closing device, including casing is vacuumized, described vacuumizes in casing from upper
Arrive down includes descending cylinder 1, upper cover base 2, upper cover 3, low head 4, low head base 5 and up cylinder 6 successively；It is described
Descending cylinder 1 be arranged on upper cover base 2 upper surface, upper cover base 2 lower surface connection upper cover 3；Under described
End socket 4 is arranged on the upper surface of low head base 5, and the lower surface of low head base 5 installs promoting the circulation of qi cylinder 6；Described upper cover 3,
The end face of low head 4 has the ripple being mutually matched；Casing is vacuumized to be connected with evacuator by vacuum tube, and by floor push
Control.
Described descending cylinder 1, up cylinder 6 are arranged on upper cover base 2, low head bottom by limited screw 7 respectively
On seat 5.
Operating method and principle：
Install：Corresponding upper cover base 2, lower envelope will be screwed in respectively with tooth shape upper cover 3, low head 4
On head base 5, fixed corresponding descending cylinder 1, up cylinder 6.It is close that upper cover 3, the ripple of low head 4 are that tooth shape must be engaged
Cut.
Arrange parameter：Upper cover 3,170 DEG C of 4 temperature of low head, vacuumize pumpdown time 4-6S in casing, vacuum
≤ -0.08MPa, seals the time：3S, end socket pressure 0.2-0.4MPa.
Method：The good battery of fluid injection is put into vacuumizing in casing of vacuumizing, airbag need to be placed on the top of low head 4,
Cavity is vacuumized by floor push control to close, and vacuumizes 4-6s, and then upper cover 3 is pushed is fully engaged against with low head 4,
The airbag of centre is set to be heated and reach sealing state.
