Description
Technical field
The utility model relates to lithium ion battery preparing technical field, relates in particular to a kind of polymer battery top package device.
Background technology
Lithium polymer battery (Li-polymer, claim again high-polymer lithium battery): it is also the one of lithium ion battery, but have compared with liquid lithium battery (Li-ion) that energy density is high, a more miniaturization, ultrathin, lightweight, and the multiple clear superiority such as high security, be a kind of novel battery.In shape, lithium polymer battery has ultrathin feature, can coordinate the needs of various products, is made into the battery of any shape and capacity.The minimum thickness that such battery can reach can reach 0.5mm.Its nominal voltage is the same with Li-ion is also nominal voltage 3.7V, there is no memory effect.
In existing polymer battery closedtop operation, the copper end socket closedtop machine that conventional counterdie, patrix are 3mm.In bottom head cushioning package board, wherein in package board, establish formatted silica gel plate.It is inhomogeneous that wherein thicker silica gel plate can cause heat conduction, easily causes and encapsulate the bad battery closedtop leakage that makes, and makes most of factory need to carry out secondary encapsulation.Simultaneously, because silica gel plate is not screw hole movably, cause the more difficult alignment of bottom head.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of polymer battery top package device, this device improves package board, not only cost-saving, simple in structure, has greatly improved battery closedtop leakage situation and has improved production efficiency.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of polymer battery top package device, comprises upper cover and bottom head, and described bottom head is provided with a package board; Described package board is made up of aluminium alloy plate and the two blocks of silica gel plates of wide 16～20mm, thick 1.5mm, and described two blocks of silica gel plates are towards upper cover, align two long limits of aluminium alloy plate are fitted on aluminium alloy plate respectively.
Preferably, described two blocks of silica gel plates are the identical plate of wide 3mm, thick 1～1.2mm size.
Preferably, described aluminium alloy plate is provided with the screw hole for debugging and locating.
Preferably, described screw hole is 3.
Preferably, described upper cover faces down on the face of end socket and posts one deck Teflon.
Preferably, Teflon is posted in the side of described bottom head.
Preferably, three layers of Teflon are posted in the side of described bottom head.Three layers of Teflon are the direction of veneer to employee's operation, effect is in order to reserve 0.5mm Wei Feng district, when aluminum plastic film rushes shell edge thinner after being stretched be approximately 70% of normal thickness, when heat-sealing can not from corner too close to, otherwise temperature can be melted brokenly aluminum plastic film internal layer CPP glue to cause battery blow-by and flatulence.
The utility model is for closedtop machine counterdie, the copper end socket that patrix is 3mm. and comprise upper cover and bottom head, described bottom head is provided with a package board; Described package board is made up of aluminium alloy plate and the two blocks of silica gel plates of wide 16～20mm, thick 1.5mm, and described two blocks of silica gel plates are towards upper cover, align two long limits of aluminium alloy plate are fitted on aluminium alloy plate respectively.The reducing in can opereating specification of thickness, can make silica gel heat conduction fast and evenly, can not need to seal up by an encapsulated moulding, repeats to seal up the damage to battery thereby reduce, and seal is evenly clear.Bottom head adopts movably silica gel plate, after aliging with upper cover when installation by screw tightening.
Brief description of the drawings
Fig. 1 is the structural representation of package board in the utility model;
Fig. 2 is the end view of package board in the utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
See Fig. 1 and 2, a kind of polymer battery top package device, comprise upper cover and bottom head, the conventional structure that other parts are this area, just repeats no more here.Bottom head is provided with a package board, and package board is made up of the aluminium alloy plate 1 of wide 16～20mm, the thick 1.5mm silica gel plate identical with two block sizes (21,22) (wide 3mm, thick 1～1.2mm).Because thickness is 1～1.2mm, more traditional other structure is used 3mm silica gel plate thin, thereby makes to be heated evenly, and improves encapsulation quality.Two blocks of silica gel plates are towards upper cover, align two long limits of aluminium alloy plate 1 are fitted on aluminium alloy plate 1 respectively.In order to save artificial tune to the time, its size can be according to actual set on aluminium alloy plate 1, to be also provided with screw hole 3 (being preferably 3) for debugging and locate.Three layers of Teflon are posted in the upper cover side of posting one deck Teflon, described bottom head on the face of end socket that faces down.
Above-described embodiment, it is preferred embodiment of the present utility model, not be used for limiting the utility model practical range, the equivalence of being done with structure, feature and principle described in the utility model claim therefore all changes or modifies, within all should being included in the utility model claim scope.
Specifically be encapsulated as:
A. starting device, check silica gel plate whether occur fracture etc. bad, if any bad, immediately change;
B. the temperature of end socket, time, pressure setting: 195 ± 5 DEG C of upper covers, 225～235 DEG C of bottom heads, soldering and sealing time 4～5S, pressure is two 2. single cylinder 0.3～0.4mpa of cylinder 0.15～0.3mpa 1..
C. battery core is put into and rushed in the darker shell of shell, negative electrode lug (what have pad on lug is positive pole), near air bag one side, makes two lugs of battery parallel and vertical with the maintenance of battery core top after putting well; Opposite side aluminum plastic film turned up and volume core is encased, rolling the upper and lower film closedtop of rear aluminum plastic film edge well concordant, lug exposes.
D. enter battery core soldering and sealing mode after shell, battery core is rushed hole place and is close to bottom head, battery core and desktop keeping parallelism, and starting switch carries out soldering and sealing.
