Description
Technical field
The utility model belongs to technical field of lithium ion, is related to a kind of aluminum plastic film expanding device of soft pack cell.
Background technology
Lithium ion battery is the representative of modern high performance battery, is widely used general.The packaging of lithium ion battery can divide
For metal shell battery core, cylindrical electrical core and soft pack cell.Soft pack cell is the battery core for having used aluminum plastic film as packaging material,
Its in the case where security risk occurs at most only can air-blowing split or not will produce more serious situation, therefore safety coefficient compared with
Height, application are more and more common.
Well known, the reservoir quantity of lithium ion battery plays a crucial role battery performance.And carry out Soft Roll electricity
When core fluid injection operation, occur the bad problem of reservoir quantity often, leads to the problem of a large amount of bad battery cores occur, reservoir quantity is undesirable to ask
Topic is in addition to fluid injection failure of pump, and dropping liquid etc. is abnormal etc., and electrolyte sputters soft pack cell when there are one very common factor being fluid injection.
Electrolyte drops to outside soft pack cell when serious, and it is relatively low not only result in soft pack cell reservoir quantity, and causes outside soft pack cell
See bad, the consequences such as corrosion inside equipment.These situations occurred, often because aluminum plastic film opening generation problem is led when fluid injection
It causes.
The mode of the existing aluminum plastic film opening for opening soft pack cell normally only carries out opening opening using sucker, such as China
Patent document is just disclosed, and application No. is a kind of vacuum liquid injecting machines of CN201620396827.3, and it discloses packed including opening
It sets, open the bag device includes being set to the movable plate of storage tank both sides, and two movable plates are equipped with opposite sucker, in two activities
Two parallel springs are fixed between plate, spring surrounds a square hole with movable plate, and the top of corresponding square hole is equipped with
The frustum set, the top of frustum are equipped with the vertically movable frustum of driving frustum and drive cylinder.The suction that the open the bag device passes through both sides
Disk carries out absorption to aluminum plastic film both sides and by driving frustum that sucker is made to pull open aluminum plastic film opening toward both sides, carries out fluid injection later.
Although by sucker can open aluminum plastic film opening, sucker suction angle clock synchronization it is easy to appear be open it is not complete
It is complete to open, or the inadequate problem of the angle opened that is open, thus the case where still will produce outer spillage when fluid injection.
Invention content
There is the above problem in the utility model, it is proposed that a kind of aluminum plastic film flaring dress of soft pack cell in view of the prior art
It sets, technical problem to be solved in the utility model is splashed outside soft pack cell outside electrolyte when how to avoid fluid injection.
