Description
Technical field
The utility model is related to a kind of core coil needle device, belongs to lithium battery manufacturing equipment field.
Background technology
Lithium-ion-power cell has operating voltage high（It is 3 times of nickel-cadmium cell and Ni-H cell）, specific energy it is big（It is reachable
165WH/kg, is 3 times of Ni-H cell）, small volume, light weight, have extended cycle life, self-discharge rate is low, memory-less effect, without dirt
Dye etc., therefore by the extensive welcome in market.
Battery core is molded by winding mechanism, when winding at present, is all since being clamped barrier film, so to roll out next battery core
Thickness ratio is larger, even if while in order to except the thickness of low battery core, the capacity of battery is also reduced, therefore proposes from pole piece and barrier film
The imagination of synchronous roll set.
Current core coil needle device inside volume pin outside using inner clip pin is set, and inner clip pin uses metal material, by interior
Press from both sides pin and clamp barrier film, when winding small battery core, roll up to process inside pin outside and be quite stranded for depositing the aobvious of inner clip pin mounting groove
It is difficult, it is easy to cause outer volume pin to be scrapped.Meanwhile, can not typically clamp pole piece using metal inner clip pin can only clamp barrier film, so that
Cause the battery core thickness of winding thickening.
The content of the invention
The purpose of this utility model be overcome the deficiencies in the prior art there is provided one kind it is simple in construction, while can be with
Clamp barrier film and the core coil needle device of pole piece can be clamped.
To solve the above problems, the technical solution of the utility model is：A kind of core coil needle device, including volume needle stand, institute
State and be also slidably fitted with active volume pin on volume needle stand on fixed fixed volume pin, volume needle stand, it is fixed in active volume pin or fixed volume pin
The check (non-return) valve communicated with air bag is installed with air bag for clamping base material, active volume pin or fixed volume pin, the check (non-return) valve enters
Gas port end is detachably connected with gas-tpe fitting, and the gas-tpe fitting ventilation can be such that air bag clamps between active volume pin and fixed volume pin
Base material；The volume needle stand offside is provided with and helps lock tube for support fixed volume pin and active volume needle end part.
Preferably, the section of the fixed volume pin and active volume pin is flat.
Preferably, the section of the fixed volume pin and active volume pin is circle.
Preferably, described help in lock tube the groove for offering and coordinating with fixed volume pin and active volume pin, and the groove
Provided with gradient.
The utility model replaces conventional metal inner clip pin, can simultaneously clamp on base material using air bag, quickly by designing air bag
Electric core winding is shaped, so as to reduce electric core winding thickness.
Brief description of the drawings
Fig. 1 is the utility model front view.
Fig. 2 is the utility model top view.
Fig. 3 is the utility model mechanism partial schematic sectional view.
Fig. 4 is the clamping schematic diagram of the utility model mechanism.
Embodiment
With reference to specific embodiment, the utility model is described in further detail, and the utility model provides the left side with Fig. 1
For a left side, using Fig. 1 right side as the right side, as shown in Figures 1 to 4：
Fixed fixed volume pin 1 can be relatively fixed volume pin 1 with active volume pin 2, active volume pin 2 is slidably fitted with volume needle stand 4
Relative movement, can put the battery core blanking just wound；Check (non-return) valve 5 is arranged on the back side of active volume pin 2, and the joint of tracheae 6 can be removable
Connection check (non-return) valve 5 is unloaded, air bag 7 is arranged in the groove of the inner side of active volume pin 2, air bag 7 can also be arranged on the fixed inner side of volume pin 1
In groove, the first barrier film 8, anode strip 9, the second barrier film 10, cathode sheets 11 are passed through among two volume pins, when tracheae 6 passes through only
Inverse valve 5 to air bag 7 inflate when, will be fixedly clamped and roll up base material between pin 1 and active volume pin 2.
Set on the right side of fixed volume pin 1 and active volume pin 2 and help lock tube 3, helped and offered in lock tube 3 and fixed volume pin 1
The groove coordinated with active volume pin 2, and the groove is provided with gradient.
Embodiment：As shown in Figures 1 to 4, after base material is drawn out, two volume pins on volume needle stand 4 stretch out setting
Distance, active volume pin 2 and fixed volume pin 1 fit through base material, and dynamic volume pin 2 is relatively fixed volume pin 1 and is displaced outwardly, help lock tube 3 to
It is left to stretch out, the valve that branch racking is rolled up on pin 2, tracheae 6 is passed through check (non-return) valve 5, inflated to air bag 7 so that air bag 7 clamps active volume
After base material between pin 2 and fixed volume pin 1, gas of substituting the bad for the good, tracheae 6 is withdrawn, and active volume pin 2 and fixed volume pin 1 start winding, work as volume
After end, the gas in air bag 7 is discharged through check (non-return) valve 5, and air bag 7 unclamps folded base material, dynamic volume pin 2 be relatively fixed volume pin 1 to
In move, convenient rolled up battery core blanking.
When the section of fixed the volume pin and active volume pin is flat, then the battery core wound is shaped as flat.
When circle is in the section of fixed the volume pin and active volume pin, then the battery core wound is shaped as circle.
Although preferred embodiment of the present utility model is described above in conjunction with accompanying drawing, the utility model not office
It is limited to above-mentioned embodiment, above-mentioned embodiment is only schematical, is not restricted, this area
Those of ordinary skill under enlightenment of the present utility model, do not departing from the utility model objective and protective scope of the claims
In the case of, the specific conversion of many forms can also be made, these are belonged within protection domain of the present utility model.
