Specific implementation mode
The utility model battery module to be detected includes several single batteries and grips the holder of single battery, branch
Each single battery is corresponded on frame, and there is through-hole, leg when which is used to weld confluence component for nickel strap to pass through, this practicality
When detecting, battery module is only assembled into holder securing unit battery to new device, and confluence component is installed not yet.
As shown in figures 1-4, a kind of device of detection lithium ionic cell module antipole, including：Support the bottom plate of mesuring battary
1, have on bottom plate 1 it is several for the first testing needle 3 by through-hole 11；It is driven and is lifted by the first cylinder 8 right over bottom plate 1
Top plate 5；Being fixed on 5 bottom surface of top plate has the upper test board 6 of several second testing needles 7；Set on 1 lower section of bottom plate by the second cylinder
4 lower test boards 2 of the driving lifting with several first testing needles 3；It is electrically connected the inspection of the first testing needle 3 and the second testing needle 7
Slowdown monitoring circuit.
Through-hole 11, the first testing needle 3, the second testing needle 7 are arranged by array.It is surveyed per the first testing needle 3 and second of a pair
Test point 7 contacts the top and bottom (anode and cathode) of single battery respectively for detecting a single battery, while contacting same
When one single battery, forming circuit has electric current, and current direction is certain.
There is the first groove 9 of limit battery, when detection battery to be put into first groove 9 for the upper surface of bottom plate 1, protect
The position and through-hole 11, the first testing needle 3 and the second testing needle 7 for demonstrate,proving each single battery correspond.The lower surface of bottom plate 1
The second groove 10 with test board 2 under limit ensures due to the position-limiting action of second groove 10 when lower test board 2 rises
It will not deviate, accordingly even when the support that lower test board 2 relies solely on the piston rod of the second cylinder 4 can also ensure the first testing needle
3 location determinations will not shift.
In order to avoid being damaged when touching battery because stress squeezes in the first testing needle 3 and the second testing needle 7,
