Description
Technical field
After the utility model is related to Soft Roll poly-lithium battery technical field, more particularly to a kind of new battery core fluid injection
Closing device.
Background technology
As the digital electric such as audio, camera apparatus, personal computer equipment is to lighting, the urgency in removableization direction
Speed development, lithium ion battery has a clear superiority at aspects such as voltage output, energy density, service lifes.Increasingly receive market
Pro-gaze.
The main type such as including square, round, polymer of lithium ion battery, wherein soft pack cell can because of the design of its structure
It is handling strong, energy density is high, it is lightweight the features such as increasingly approved by market.In battery core manufacturing process, the sealing of battery core
Technique is particularly important, and it determines the overall sealing of battery core.And the leakage problem of fluid injection sealing is solved at present, however it remains one
Fixed problem.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art and provides the envelope after a kind of new battery core fluid injection
Mouth device, the closing device modern design after the new battery core fluid injection, simple structure improve battery core sealing fastness, reduce
Battery core leakage, improves product percent of pass, improves enterprise profit.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions.
A kind of closing device after new battery core fluid injection, include sealing and the upper die head in strip and correspondence
The lower die head matched somebody with somebody, is provided with V-shaped projection on upper die head lower surface, be provided with lower die head upper surface it is V-shaped and
The groove matched with projection.
Wherein, the central shaft of the projection is identical with the central shaft of the upper die head.
Wherein, the central shaft of the groove is identical with the central shaft of the lower die head.
Wherein, when the lower die head of upper die head and Corresponding matching is closed, the projection lower end connects with the bottom of the groove
Touch.
The beneficial effects of the utility model are：Sealing dress after a kind of new battery core fluid injection described in the utility model
Put, include sealing and the upper die head in strip and Corresponding matching lower die head, be provided with upper die head lower surface V-shaped
The projection of shape, is provided with groove that is V-shaped and matching with projection on lower die head upper surface.The utility model has design
Novel, simple structure, improves battery core sealing fastness, reduces battery core leakage, improves product percent of pass, improves the excellent of enterprise profit
Point.
Brief description of the drawings
The utility model is further detailed below with accompanying drawing, but the embodiment in accompanying drawing do not constitute it is right
Any limitation of the present utility model.
Fig. 1 is structural representation of the present utility model.
Include in Fig. 1：
1 --- upper die head 11 --- projection
2 --- lower die head 21 --- grooves.
Specific embodiment
The utility model is illustrated with reference to specific embodiment.
As shown in figure 1, the closing device after a kind of new battery core fluid injection, include sealing and the upper mould in strip
First 1 and the lower die head 2 of Corresponding matching, V-shaped projection 11 is provided with the lower surface of upper die head 1, lower die head 2 sets on upper surface
It is equipped with groove 21 that is V-shaped and matching with projection 11.
Further, the central shaft of the projection 11 is identical with the central shaft of the upper die head 1.
Further, the central shaft of the groove 21 is identical with the central shaft of the lower die head 2.
Further, when the lower die head 2 of upper die head 1 and Corresponding matching is closed, the lower end of the projection 11 is recessed with described
The bottom contact of groove 21.
Need to further explain, the utility model in glove box in capping processes are carried out, it is ensured that at battery core inside
In the state of sealing, the battery core after fluid injection is needed to be placed in closing device, and closing device is first vacuumized and keeps certain hour,
, it is necessary to air sac belt is placed between upper die head 1 and lower die head 2 when battery core is sealed, and ensure that battery core air bag has 3mm or so to stretch
Go out, then upper die head 1 and lower die head 2 are closed, and battery core air bag is sealed with groove 21 by projection 11, therefore the utility model
With novel in design, simple structure, battery core sealing fastness is improved, reduce battery core leakage, improve product percent of pass, improve enterprise
The advantage of profit.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, will change in specific embodiments and applications, this specification content should not be construed as
To limitation of the present utility model.
