Detailed description of the invention
Combine accompanying drawing below by detailed description of the invention the application is described in further detail.
Embodiment one:
Refer to Fig. 1, the embodiment of the present application provides a kind of lithium ion battery coil pin mechanism, including the first half round rolls
Pin 1A and the second half round roll pin 1B, the first half round roll pin 1A and the second half round roll pin 1B phases are assembled, assembling
After the longitudinal section of the working region 10 of rolling needle mechanism that obtains be circle, working region 10 is used for gripping barrier film.
As shown in Figure 2 A, in the first direction, vertical on the first wrapping range 10A of the first half round roll pin 1A
The radius of tangent plane becomes larger, and first direction is to extend from the root position C1 ' near the first half round roll pin 1A
To the apical position C1 near the first half round roll pin 1A.
As shown in Figure 2 B, in a second direction, vertical on the second wrapping range 10B of the second half round roll pin 1B
The radius of tangent plane tapers into, and second direction is to extend from the root position C2 ' near the second half round roll pin 1B
To the apical position C2 near the second half round roll pin 1B.
After the first half round roll pin 1A and the second half round roll pin 1B assemblings, working region 10 is often located longitudinal section
Diameter is identical.
According to this embodiment, it can know, above-mentioned working region 10 comprises the first wrapping range 10A and
Two wrapping range 10B.First wrapping range 10A and the second wrapping range 10B is combined into working region 10.
It is worthy of note, in this example, the first half round roll pin 1A and the second half round roll pin 1B are assembled together
After, the diameter that working region 10 is often located longitudinal section is identical.Thus it is recognised that above-mentioned first direction
Refer to same direction, above first direction and second direction with second direction and carry out stating merely to more
The first half round roll pin 1As and the structure of the second half round roll pin 1Bs are explicitly described.Significantly, since
The diameter often locating longitudinal section on working region 10 is identical, it is therefore to be understood that the first half round roll pins
The position that on the position accordingly and the second half round roll pin 1B that 1A upper longitudinal section radius is bigger, longitudinal section radius is less
Assembling.
In one embodiment, the first half round roll pins are provided with at least two gap, place platforms 2.
As shown in figs. 3 a-3 c, all assemble at mould at the first half round roll pin 1A and the second half round roll pin 1B
During upper relevant position, the first half round roll pin 1A and the second half round roll pin 1B are completely integrated, owing to there being gap to put down
Platform, the inner surface of the first half round roll pin 1A and the second half round roll pin 1B retains certain in the position of gripping barrier film
The gap of distance, it is ensured that barrier film is not squeezed in centre position.It addition, the first half round roll pin 1A and second
The when that half round roll pin 1B mould exiting, the gap platform on the first half round roll pin 1A more serves expansion lithium
The benefit of the centre bore 3 of ion battery products, reduce the centre bore of lithium ion battery product produced non-round,
The problems such as centre bore blocking, Improving The Quality of Products, also reduces the equipment fault of slot rolling device simultaneously.
The structural representation of the lithium ion battery wound for the rolling needle mechanism life of prior art as shown in Figure 4 A,
Wherein it is possible to see, owing to existing rolling needle mechanism is made up of mutually isostructural two parts volume pin, produce
The shape of the centre bore 3 ' of the lithium ion battery product gone out also is by being shaped like, two parts group that size is close
Become, middle in serpentine shape.As shown in Figure 4 B, utilize the rolling needle mechanism lithium that obtains of winding of the application from
The centre bore 3 of sub-battery is made up of the two parts varied in size, thus is expanded by centre bore barrier film, plays expansion
The effect in hole, reduces the probability that barrier film is destroyed, reduces the appearance of blockage problem during follow-up boiling hot hole.
In one embodiment, the height of gap platform 2 is 0.2mm.
In one embodiment, the quantity of gap platform 2 is two, a top near the first half round roll pins
Position C1 is arranged, and another is arranged near the root position C1 ' of the first half round roll pins.
In one embodiment, the gap platform 2 arranged near the apical position C1 of the first half round roll pin 1A
Axial length is 30mm.
In one embodiment, the gap platform 2 arranged near the root position C1 ' of the first half round roll pin 1A
Axial length is 5mm.
The lithium ion battery coil pin of the application is being wound work, when performing to insert die procedure, due to the
Half round roll pin 1A inner surface has gap platform, and the second half round roll pin 1B do not easily cause raw-material when inserting
Deformation or damage.When die procedure is exited in execution, rolling needle mechanism uses separately the mode of secession to pull out inside battery core
Go out, first exit the second half round roll pin 1B, then exit the first half round roll pin 1A.Due to the second half round roll pin 1B
Sectional area is the least the closer to apical position C2, so not easy damaged battery raw material.Due to the embodiment of the present application
Rolling needle mechanism eliminate the trench design on conventional roll pin, decrease volume pin itself abrasion, it is ensured that mould
In the tool life-span, also reduce the damage to lithium ion battery product simultaneously, improve the matter of lithium ion battery product
Amount.
It is understood that the embodiment of the present application is mainly used in the winding of the lithium ion battery of column type,
In other embodiment, it is also possible to the rolling needle mechanism to the lithium ion battery of the most square or other shapes
Make above-mentioned improvement.Such as tip designs Cheng get Geng by a portion of rolling needle mechanism is little, facilitates the withdraw of the needle.
And for example, gap platform can be set on volume pin, the centre bore of the lithium ion battery product that expanding production goes out,
Promote battery quality.
The application provides a kind of lithium ion battery coil pin mechanism, when being wound work, by rolling needle mechanism
Inserting mould, owing to the first half round roll pin inner surfacies have gap platform, the second half round roll pins are difficult to make when inserting
Become raw-material deformation or damage.When die procedure is exited in execution, first exit the second half round roll pins and exit again
Half round roll pin.Owing to the sectional area of the second half round roll pins is the least the closer to front end, so not easy damaged battery
Raw material.The rolling needle mechanism that the application provides eliminates the design of groove, decreases the mill of rolling needle mechanism itself
Damage, it is ensured that also reduce the damage to product while die life, it is ensured that the quality of product.Profile
Simply, convenient processing, reduces processing cost.
The application is illustrated by use above specific case, is only intended to help and understands the application, not
In order to limit the application.For the application person of ordinary skill in the field, according to the thought of the application,
Some simple deductions can also be made, deform or replace.
