Description

Lithium ion polymer battery core packaging line closedtop end socket

Technical field

The utility model belongs to lithium battery electric core encapsulation technology research field, is related to a kind of lithium ion polymer battery core by it Packaging line closedtop end socket.

Background technique

Lithium ion polymer battery is a kind of secondary cell, also known as macromolecule battery, rely primarily on lithium ion in anode and Movement between cathode carrys out work, has many advantages, such as that monomer voltage is high, specific energy is high, light, cleanliness without any pollution.In shape, The poly- battery of lithium has ultrathin feature, can cooperate the battery of different product production different shape and capacity, what theory can make Minimum thickness is mainly used in the associated portable electronics equipment such as mobile phone, notebook up to 0.2mm.The poly- battery of lithium includes electricity Core and protection circuit two parts, battery core is main part, and need to could be used as complete battery normally after circuit is protected in installation makes With.In the production process of the poly- battery core of lithium, battery core closedtop is an essential process, and the battery core sealed firmly by closedtop is being sealed Filling has high consistency on thickness, and encapsulates pulling force and meet SPEC requirement, reduces the risk of leakage, makes battery core more Beauty, facilitate it is subsequent protection circuit installation.

The defect of existing closedtop envelope end socket is: in order to keep the planar horizontal to bind, the end face of upper closedtop end socket is equal For horizontal structure, and the position of the surplus of the aluminum plastic film encapsulated ahead of the curve can be presented irregular undaform, upper in encapsulation process, The shell surplus of lower two layers of aluminum plastic film was both nowhere discharged or can not be absorbed, so surplus easily forms accumulation when binding, into And form the defect of fold.

Utility model content

The utility model proposes a kind of lithium ion polymer electricity for the problems in above-mentioned background technique of effective solution Core packaging line closedtop end socket, specific technical solution are as follows:

A kind of lithium ion polymer battery core packaging line closedtop end socket, including lower closedtop end socket and upper closedtop end socket, under described It is equipped with boss among closedtop end socket end face, the groove with the boss clearance fit is equipped among the upper closedtop end socket end face；

Preferably, the boss is trapezoid boss；

Preferably, the gap between boss and groove is 0.2mm；

Preferably, the upper bottom of the trapezoid boss is 3mm, is gone to the bottom as 5mm, a height of 1~2mm；

The utility model compared with prior art, is had an advantage that: by be arranged in lower closedtop end socket boss and upper top The groove for sealing end socket, the aluminum plastic film for keeping battery core closedtop extra when encapsulating, is filled in the gap of boss and groove, thus by plastic-aluminum Film is washed, meanwhile, the gap size of boss and groove is equal to the package thickness of aluminum plastic film, the aluminum plastic film between concave-convex fit structure It can be encapsulated as trapezoidal, and the colloidal sol effect of the trapezoid area in aluminum plastic film forward position and package thickness meet SPEC requirement, thus The end socket that makes to bind above and below has the function of removing closedtop fold, while the fold operation of closedtop is removed by the end socket that binds above and below It is convenient, cleaned convenient for employee, effectively the lifting means rate of transferring and fold fraction defective can be reduced, had very strong practical.

Specific embodiment

In order to make those skilled in the art better understand the scheme of the utility model, with reference to the accompanying drawing and embodiment The utility model is described in further detail.

A kind of lithium ion polymer battery core packaging line closedtop end socket, including lower closedtop end socket 1 and upper closedtop end socket 2, it is described It is equipped with boss among lower closedtop end socket end face, is equipped among the upper closedtop end socket end face recessed with the boss clearance fit Slot；The boss is trapezoid boss 3；Gap between the matched trapezoidal groove 4 of trapezoid boss is 0.2mm；

The upper bottom of the trapezoid boss is 3mm, is gone to the bottom as 5mm, a height of 1~2mm；

In closedtop encapsulation process, encapsulation movement be upper closedtop end socket it is first upward, then descend closedtop end socket still further below with it is upper Closedtop end socket closure completes encapsulation, lower closedtop end socket during moving upwards, boss structure on end socket can first with aluminium Plastic film is in contact and jacks up aluminum plastic film, and originally wavy aluminum plastic film forward position surplus is just washed by boss structure, lower closedtop Boss structure height on end socket only 1~2mm, aluminum plastic film will not be pulled apart under the premise of aluminum plastic film surplus is washed and The offset of pole group is not will cause, the gap size between the groove of upper closedtop end socket and the boss of lower closedtop end socket is exactly equal to plastic-aluminum The package thickness of film, the aluminum plastic film between concave-convex fit structure can be encapsulated as trapezoidal, and the trapezoid area in aluminum plastic film forward position Colloidal sol effect and package thickness meet SPEC requirement, the position that the trapezoid boss on upper closedtop end socket contact with battery is to be open The pre- trimming position of side battery will be cut completely by the trapezoidal plastic-aluminum diaphragm area that male-female engagement end socket encapsulates in pre- trimming It removes, the appearance of p-wire blanking battery is no different with normal battery.

Application method is as follows:

It needs first to verify the appearance of end socket and size before use, it is desirable that end socket surface goes flash removed, seamed edge that need to fall It is blunt, surface is smooth and uniform color, upper closedtop end socket limiting stand height and the aluminum plastic film specification of packaged battery size want phase Matching, upper closedtop end socket tab position fluting size meet technique requirement.

The end socket qualified to verification is installed, especially to pay attention in installation process upper closedtop end socket must be aligned, lower top Boss on envelope end socket will be engaged with the groove on upper closedtop end socket.In addition to it is above-mentioned need the project of great care other than, closedtop Fold improve end socket installation method be no different with common closedtop end socket, application method with put inspection project also with common closedtop end socket one It causes.

The design of exploitation of the utility model: aluminum plastic film quality is soft, turnover fixture out-of-flatness and chucking surface sucker are drawn In the case where pulling, closedtop fold easily occurs for battery forward position, so being conceived from actual use demand, while considering work Efficiency and fool proof are innovated on the basis of untouched header structure, and the boss with fold removal function installed additional can be It is promoted on all polymer soft-package batteries, the structure of boss has versatility.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of utility model.
