But, in electrolyte due to flexible packing lithium ion battery, comprised the mixed solvent that multiple organic solvent forms, if solvent leaks, will cause catching fire, the potential safety hazard such as blast, so the package reliability of the aluminum-plastic composite membrane of flexible packing lithium ion battery is most important.
In existing manufacturing process, the encapsulation of aluminum-plastic composite membrane mainly comprises closedtop and side seal, and wherein, closedtop is that the aluminum-plastic composite membrane of lug external part is encapsulated.Conventional closedtop end socket comprises end socket base and auxiliary heating piece at present, connect, and auxiliary heating piece screw periphery is provided with spring between end socket base and auxiliary heating piece by auxiliary heating piece screw.Auxiliary heating piece of the prior art be shaped as cuboid; adjustable in order to guarantee the height of auxiliary heating piece; auxiliary heating piece screw just can not be locked; that is to say that auxiliary heating piece screw becomes flexible in process of production; this has just caused auxiliary heating piece in process of production often to there will be inclination, come off and the phenomenon such as stuck; cause the encapsulation of batch property bad, the sealing quality of battery is had to larger impact.
In view of this, necessary a kind of flexible packing lithium ion battery closedtop end socket that provides, this end socket is by improving the structure of auxiliary heating piece, increased the degree of depth of screw locking, thereby improved the Assembly stability of auxiliary heating piece, eliminated the encapsulation causing built on the sand because of auxiliary heating piece bad, improved the excellent rate of encapsulation and the stabilization of equipment performance of battery, avoided controlling out of control because encapsulating the unstable process control inefficacy causing and product quality.
Utility model content
The purpose of this utility model is: for the deficiencies in the prior art, and provide a kind of flexible packing lithium ion battery closedtop end socket, this end socket is by improving the structure of auxiliary heating piece, thereby increased the degree of depth of screw locking, thereby improved the Assembly stability of auxiliary heating piece, eliminated the encapsulation causing built on the sand because of auxiliary heating piece bad, improved the excellent rate of encapsulation and the stabilization of equipment performance of battery, avoided controlling out of control because encapsulating the unstable process control inefficacy causing and product quality.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of flexible packing lithium ion battery closedtop end socket, comprise end socket base and auxiliary heating piece, between described end socket base and described auxiliary heating piece, by auxiliary heating piece screw, connect, and described auxiliary heating piece screw periphery is provided with spring, described auxiliary heating piece comprises contiguous block and is arranged at the heat block of described contiguous block lower surface.
A kind of improvement as the utility model flexible packing lithium ion battery with closedtop end socket, the two ends of described contiguous block are provided with screw hole, and described auxiliary heating piece screw is arranged in described screw hole.
A kind of improvement as the utility model flexible packing lithium ion battery with closedtop end socket, the length of described contiguous block is greater than the length of described heat block.
A kind of improvement as the utility model flexible packing lithium ion battery with closedtop end socket, the thickness of described contiguous block is less than the thickness of described heat block.
A kind of improvement as the utility model flexible packing lithium ion battery with closedtop end socket, described screw hole be take the longitudinal centre line of described contiguous block and is arranged at symmetrically the two ends of described contiguous block as symmetry axis.
A kind of improvement as the utility model flexible packing lithium ion battery with closedtop end socket, described contiguous block and described heat block are set to integrated formed structure.
With respect to prior art, the utility model is by improving the structure of auxiliary heating piece, thereby increased the degree of depth of auxiliary heating piece screw locking, improved the Assembly stability of auxiliary heating piece, eliminated the encapsulation causing built on the sand because of auxiliary heating piece bad, improved the excellent rate of encapsulation and the stabilization of equipment performance of battery, avoided controlling out of control because encapsulating the unstable process control inefficacy causing and product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the auxiliary heating piece in the utility model.
Wherein, 1-end socket base, 2-auxiliary heating piece, 21-contiguous block, 22-heat block, 23-screw hole, 3-auxiliary heating piece screw, 4-spring.
Embodiment
Below in conjunction with the drawings and specific embodiments, describe the utility model and beneficial effect thereof in detail, still, execution mode of the present utility model is not limited to this.
As depicted in figs. 1 and 2, a kind of flexible packing lithium ion battery closedtop end socket that the utility model provides, comprise end socket base 1 and auxiliary heating piece 2, between end socket base 1 and auxiliary heating piece 2, by auxiliary heating piece screw 3, connect, and auxiliary heating piece screw 3 peripheries are provided with spring 4, auxiliary heating piece 2 comprises contiguous block 21 and is arranged at the heat block 22 of contiguous block 21 lower surfaces.
Wherein, contiguous block 21 two ends are provided with screw hole 23(as shown in Figure 2), auxiliary heating piece screw 3 is arranged in screw hole 23.The effect of contiguous block 21 is mainly that end socket base 1 and auxiliary heating piece 2 are coupled together, and heating when auxiliary heating piece 2 is mainly used in encapsulating is bonded together two-layer packaging film heating and melting, and then realizes sealing.End socket base 1 is mainly used in providing pressure, and two-layer packaging film is closely sealed, and prevents that electrolyte leakage in battery from out, causing potential safety hazard.
The length of contiguous block 21 is greater than the length of heat block 22.Preferably, screw hole 23 is arranged on the part that contiguous block 21 grows heat block 22, so, on heat block 22, just without the hole of passing for auxiliary heating piece screw 3 is set, only by contiguous block 21Shang hole, just can be realized effectively and connecting.
The thickness of contiguous block 21 is less than the thickness of heat block 22, and this is because contiguous block 21 is only the effect of playing connection, does to such an extent that too thick meeting causes the unnecessary waste of material, and heat block 22 need to heat packaging film, need to accomplish certain thickness.
Screw hole 23 be take the longitudinal centre line of contiguous block 21 and is arranged at symmetrically contiguous block 21 two ends as symmetry axis, is convenient to the assembling of auxiliary heating piece 2, and easily guarantees that the bottom of the auxiliary heating piece 2 after assembling flushes with horizontal plane.
In a word, the utility model is by improving the structure of auxiliary heating piece 2, thereby increased the degree of depth of auxiliary heating piece screw locking 3, improved the Assembly stability of auxiliary heating piece 2, eliminated the encapsulation causing built on the sand because of auxiliary heating piece 2 bad, improved the excellent rate of encapsulation and the stabilization of equipment performance of battery, avoided controlling out of control because encapsulating the unstable process control inefficacy causing and product quality.
It should be noted that, the announcement of book and elaboration according to the above description, the utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should be in the protection range of claim of the present utility model to equivalent modifications more of the present utility model and change.In addition,, although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
