Among the figure: the 1-battery tray 2-first lead 3-first metal holder 4-first metal copper sheet 5-needle-like metal projection 6-second lead 7-second metal holder 8-second metal copper sheet
Embodiment
For further specifying the utility model, existing conjunction with figs. is set forth in detail:
As shown in Figure 1; Said polymer Li-ion battery aluminum plastic film damage survey device; Form by battery tray 1, first lead 2 and second lead 6; Wherein first lead, 2 one ends are provided with and are used for and the first fixing metal holder 3 of polymer battery anode ear, and the other end is the first metal copper sheet 4, and contacts with battery tray 1 through this first metal copper sheet 4; On the metal copper sheet 4 of first lead 2, also be fixed with the needle-like metal projection 5 that is used to pierce through aluminum plastic film, said needle-like metal projection 5 is the metallic copper material; Second lead, 6 one ends are provided with and are used for and second metal holder 7 that the polymer battery negative electrode lug is fixing, and the other end is for falling the second metal copper sheet 8 of T-shape (⊥), and contact with battery tray 1 through this second metal copper sheet 8.
During use; Aluminum plastic film to be measured is fixed on the battery tray 1 with adhesive tape; First metal holder 3 of first lead 2 is clipped on the anode ear of polymer battery; Second metal holder 7 of second lead 6 is clipped on the negative electrode lug of polymer battery, and the first metal copper sheet 4 places the below of plastic-aluminum shell, and needle-like metal projection 5 punctures the plastic-aluminum shell.
When detecting aluminum plastic film inside, in battery container, pour copper-bath into, the second metal copper sheet 8 is put into battery case, lead as power turn-on, can be tested polymer battery; When detecting battery aluminum plastic film outside, in battery tray 1, pour copper-bath into, the submergence battery case; The first metal copper sheet 4 places the below of plastic-aluminum shell; Needle-like metal projection 5 punctures the plastic-aluminum shell, and the second metal copper sheet 8 is put into battery tray 1, lead with polymer battery as power turn-on; Placed 12 hours, and can obtain testing result.If the aluminum plastic film surface has copper to separate out, represent that then there is breakage on this aluminum plastic film surface, otherwise then do not have.
It is thus clear that polymer Li-ion battery aluminum plastic film damage survey device according to the invention uses the lead of band metal holder can change power supply easily, the time spent is not taken off lead, can not produce the danger of power supply short circuit, and fail safe is good; And power supply is convenient for changing after damaging; The design of needle-like metal projection 5 is convenient to pierce through aluminum plastic film, forms excellent contact with aluminium lamination, and sheet metal is smooth, can remain on fixing position; Metal copper sheet 8 adopts " ⊥ " type copper sheet, and can be stable fix in the plane can not break away from solution because fixing shakiness, and influence detection effect can prevent effectively that solution from contacting with the lead interior metal simultaneously, prevents to corrode, and prolongs service life of equipment.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
