Description
Technical field
The utility model relates to battery manufacturing process equipment technical field, especially relates to a kind of closedtop end socket of flexible packing lithium ion battery.
Background technology
As rechargeable lithium ion batteries of new generation, it is high that lithium ion battery has voltage, and specific energy is large, have extended cycle life, be subject to advantages of environment protection a lot of users' favors.Polymer Li-ion battery is compared the advantage that traditional lithium ion battery has kept traditional lithium ion battery, has improved its specific energy and security performance simultaneously.At present, increasing electronic equipment adopts flexible packing lithium ion battery as its power supply, and along with the lifting that power consumption equipment requires lithium ion battery, lithium ion battery is towards high-energy-density and high magnification future development, and this just requires battery pole ear to broaden greatly.Along with broadening of lug is large, polymer Li-ion battery closedtop improves the requirement of temperature, time and pressure.Closedtop is one of important production process of lithium ion battery, and this operation is that the tab of the two-layer aluminum plastic film of lithium ion battery and positive and negative lug is packaged together by certain temperature, time and pressure, thereby plays the effect being isolated from the outside.The packaging system adopting is at present that upper bottom head only heats cell aluminum-plastic membrane and tab encapsulation position, and lug does not contact end socket, can not directly obtain heat from end socket.In the time of the large lug battery of encapsulation, because lug is made up of metal material, its heat radiation is very fast, causes the actual temperature of closedtop not reach requirement, and this can cause cell package quality not firm, causes battery to have the risk of leakage.If raising closedtop temperature can cause again the excessive encapsulation of the electrodeless ear portions in top, this easily causes battery short circuit.
Utility model content
The purpose of this utility model is to provide a kind of closedtop end socket of flexible packing lithium ion battery.It can carry out auxiliary heating to lug, thereby it is firm or encapsulate excessive problem to solve encapsulation.
The technical solution of the utility model is: a kind of closedtop end socket of flexible packing lithium ion battery, comprise upper cover and bottom head, on the described upper cover surface relative with bottom head, be provided with the partition grooves of upper and lower correspondence, end socket is divided into aluminum plastic film encapsulation region and lug auxiliary heating district by described partition grooves, described aluminum plastic film encapsulation region and lug auxiliary heating district lay respectively at partition grooves both sides, the level height of lower surface, described upper cover lug auxiliary heating district is lower than the level height of lower surface, aluminum plastic film encapsulation region, and described bottom head upper surface is fixed with silica gel strip.
Further, the upper surface of described bottom head is provided with multiple little grooves, and described silica gel strip is by covering on the upper surface of bottom head with the mode of little recess-mounted.
Further, the lower surface in described upper cover aluminum plastic film encapsulation region and lug auxiliary heating district is plane.
The beneficial effects of the utility model are: first, the utility model is widened end socket, and lug can obtain heat from end socket widened section, can keep the heat of aluminum plastic film encapsulation region not scatter and disappear, thereby have reduced the illusive phenomenon of encapsulation; Secondly, upper cover auxiliary heating district exceeds aluminum plastic film encapsulation region, and is inlaid with the silica gel strip of elasticity and heat conduction in bottom head auxiliary heating part, makes lug be close to end socket, thereby makes heat be delivered to better lug; In addition, because lug auxiliary heating district and aluminum plastic film encapsulation region integrate, without extra heating sources, end enclosure structure is simpler, saves material, is easy to processing.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As illustrated in fig. 1 and 2, end socket of the present utility model is made up of upper cover 1 and bottom head 2, on upper cover 1 surface relative with bottom head 2, be provided with the partition grooves 5 of upper and lower correspondence, end socket is divided into Liang Ge district by partition grooves 5, left field is aluminum plastic film encapsulation region 3, and right side area is lug auxiliary heating district 4.The level height of 4 lower surfaces, upper cover lug auxiliary heating district is lower than the level height of 3 lower surfaces, aluminum plastic film encapsulation region, and difference in height is between the two a.Wherein, the thickness sum of the thickness that the height of a is two-layer aluminum plastic film and two-layer tab, is about 0.4mm, and the width of partition grooves is 1.5～3mm.On upper cover 1, the lower surface in aluminum plastic film encapsulation region 3 and lug auxiliary heating district 4 is plane.On bottom head 2, be also provided with multiple little grooves 11, on little groove 11, be inlaid with silica gel strip 6, silica gel strip 6 covers on the upper surface of bottom head 2.Upper cover top be provided with for the fixing cylinder mounting holes 12 of the cylinder of heater, bottom head bottom is provided with for bottom head being fixed on to the base installing hole 14 on the utility model heater base, and upper bottom head side is provided with the temperature probe installing hole 13 for temperature probe is installed.
Be structural representation and the cutaway view of flexible packing lithium ion battery 7 as shown in Figures 3 and 4, when encapsulation, the front end of flexible packing lithium ion battery 7 extend between upper cover 1 of the present utility model and bottom head 2 from left to right.Aluminum plastic film 8 is placed in to aluminum plastic film encapsulation region 3, lug 9 is placed in to lug auxiliary heating district 4.After placing, cylinder promotes upper cover 1 and moves to bottom head 2, aluminum plastic film 8 the heating of aluminum plastic film encapsulation region 3 with compress under combine closely with inner tab 10.Compressed and lug 9 also has the silica gel strip 6 of elasticity and good heat transfer function, and can obtain heat from upper and lower end socket by lug auxiliary heating district 4.Due to the partition effect of partition grooves 5, the heating of the heating of aluminum plastic film 8 and lug 9 does not interfere with each other, thereby reaches good packaging effect.Meanwhile, the glue stain end socket that when partition grooves 5 can also be avoided encapsulating, aluminum plastic film overflows, and then affect package quality.
The above; be only embodiment of the present utility model, it should be pointed out that any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.
