Abstract
The utility model belongs to the field of lithium ion batteries and particularly relates to a sucker structure. The sucker structure comprises an outer sucker and an inner sucker, the outer sucker is provided with a through hole, one end of the inner sucker is inserted into the through hole and in close fit with the same. Compared with the prior art, the sucker structure has the advantages that the inner sucker is arranged in the outer sucker, deformation of an air bag due to mislocation of the suckers is avoided, suction failure rate is reduced, yield rate is increased and production period is shortened.
Description
Technical field
The utility model belongs to the lithium ion battery field, relates in particular to a kind of sucker structure.
Background technology
In present lithium ion battery industry, the fluid injection sucker of filling machine all adopts the sucker of standard, and what basically adopt is outer sucker structure, and it is large to adopt this structure to cause the battery core airbag to inhale not open ratio, and it is more and more to cause battery core to do over again in batch production like this.
The utility model content
The purpose of this utility model is: inhale not open the large deficiency of ratio for the battery core airbag of prior art, and a kind of sucker structure is provided, this structure can make the battery core airbag inhale not open the ratio minimizing, improve yields, has shortened the production cycle.
For achieving the above object, the utility model adopts following technical scheme:
A kind of sucker structure comprises outer sucker and interior sucker, and wherein, described outer sucker is provided with through hole, and an end of described interior sucker inserts described through hole, and with described through hole tight fit.
A kind of improvement as sucker structure described in the utility model, described interior sucker comprises interior sucker neck and interior sucker air flue, described interior sucker air flue is arranged at described interior sucker center and coaxial with described outer sucker, and described interior sucker neck is arranged at an end of interior sucker.
As a kind of improvement of sucker structure described in the utility model, described interior sucker neck is provided with interior sucker head.
As a kind of improvement of sucker structure described in the utility model, described outer sucker is provided with outer sucker head.
As a kind of improvement of sucker structure described in the utility model, the distance of described interior sucker head and described outer sucker head is 1cm-3cm.
As a kind of improvement of sucker structure described in the utility model, the distance of described interior sucker head and described outer sucker head is 2cm.
As a kind of improvement of sucker structure described in the utility model, described interior sucker air flue is connected with the vacuum tracheae of outside.
Useful technique effect of the present utility model is: the utility model comprises outer sucker and interior sucker, wherein, described outer sucker is provided with through hole, one end of described interior sucker inserts described through hole, and with described through hole tight fit, avoided the sucker dislocation to cause the airbag distortion by said structure, reduced and inhale not open ratio, improve yields, shortened the production cycle.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
As shown in Figure 1, a kind of sucker structure comprises outer sucker 1 and interior sucker 3, and wherein, outer sucker 1 is provided with through hole (among the figure without sign), and an end of interior sucker 3 inserts through hole, and with the through hole tight fit.
Wherein, interior sucker 3 comprises interior sucker neck 2 and interior sucker air flue 4, and interior sucker air flue 4 is arranged at interior sucker 3 centers and coaxial with outer sucker 1, and interior sucker neck 2 is arranged at an end of interior sucker 3.
Wherein, interior sucker 3 necks are provided with interior sucker head 7.
Wherein, outer sucker 1 is provided with outer sucker head 6.
Wherein, the distance of interior sucker head 7 and outer sucker head 6 is 1cm-3cm.
Wherein, the distance of interior sucker head 7 and outer sucker head 6 is 2cm, when distance when being 2cm, and novel optimal distance for this reason.
Wherein, interior sucker air flue 4 is connected with the vacuum tracheae of outside, and the vital qi tracheae is connected with a machine that produces air.
The course of work of the present utility model is: when outer sucker 1 contact airbag, outer sucker 1 stress deformation, then interior sucker 3 contacts airbags, again because interior sucker air flue 4 connects a vacuum tracheae, vacuum all is full of vacuum by interior sucker air flue 4 in interior sucker 3 and outer sucker 1, hold simultaneously airbag and be close to interior sucker 3 and outer sucker 1, interior sucker 3 is fixed by interior sucker screw thread.
The according to the above description announcement of book and instruction, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to the utility model just for convenience of description.
