In step S02, by cylinder 11, promote sliding bar 122 along guide rod 121 down slidings, drive three probes 131,132 and 14 to move down simultaneously, until abut to anode ear 21, negative electrode lug 22 and aluminum plastic film, because aluminum plastic film is coated by shell 23 conventionally, can pierce through shell 23 by probe 14, so that probe 14 close contacts are to aluminum plastic film.In this process, three probes 131,132 and 14 synchronously move down, action simultaneously, and convenient to operation, efficient, measurement result is more accurately and reliably.The short-circuit detecting precision of the present embodiment can reach 100%.
Determine that when three place's probes 131,132 and 14 touch respectively site separately simultaneously, power-on 102, opens testing circuit, when practical operation, as long as one opens power supply, will there is immediately testing result, whether aluminum plastic film short circuit and battery core short circuit exist and will find simultaneously.Particularly, as previously mentioned, consult Fig. 5, by detecting circuit connection between the anode ear 21 of battery and the lug detector probe of negative electrode lug 22 131,132, whether exist abnormal, if there is abnormal (as having short circuit between anode ear 21 and negative electrode lug 22), battery core short circuit hummer 172 flicker that can pipe, judges that battery 20 is for battery core short circuit.Simultaneously, detect between film detector probe 14 and lug detector probe 131,132 circuit and is connected and whether exists extremely, if existence extremely, for example, between film detector probe 14 and anode ear 21, have short circuit, aluminum plastic film short circuit hummer 171 flicker that can pipe, judges that battery is aluminum plastic film short circuit.Conventionally aluminum plastic film and anode ear 21 and negative electrode lug 22 one of them be normally electrically connected, normally can keep being communicated with negative electrode lug, and need insulation with anode ear 21, therefore, when conducting appears in both that detect to occur need insulation, judge that battery is aluminum plastic film short circuit, not conducting and with another conducting, be normal.Certainly, during detection, if reporting to the police appears in aluminum plastic film short circuit hummer 171 and battery core short circuit hummer 172 simultaneously, judge that so battery core short circuit and aluminum plastic film short circuit exist simultaneously.
When mesuring battary 20 only being detected and have aluminum plastic film short circuit, further, by mesuring battary 20 dismountings, again change after the housing of battery core, then the battery after refitting carries out aforementioned detecting step.Therefore, so judge exactly the state of battery core, reduce erroneous judgement, the probability such as fail to judge, has reduced the potential safety hazard producing because of battery core short circuit and has dropped to minimumly, meanwhile, has met client's requirement, the product quality having promoted.And short circuit repacks for aluminum plastic film, avoid available battery waste, reduce costs, improve product yield.As long as for the situation that battery core short circuit detected, this battery 20 is scrapped to processing.
As from the foregoing, the operation of two kinds of electric circuit inspection is very simple, and easily, and the pick-up unit of the present embodiment is not subject to time, environment, material, personnel's shadow noon in judgement, can be according to the model of battery, and different lug centre distance regulate and detect.During work, can regulate according to the width of lug, can meet different model, different lug width, the testing requirement of different lug centre distance width.
Above-mentioned lithium ion battery short-circuit detecting device and method, adopt lug detector probe 13 to survey between anode ears 21 and negative electrode lug 22 whether short circuit, to judge whether to exist battery core internal short-circuit, with film detector probe 13 detection aluminum plastic films and inside battery, whether there is short circuit.And lug detector probe 13 and film detector probe 14 are to be synchronized with the movement, can synchronously side by side detect and distinguish battery is battery core short circuit or aluminum plastic film short circuit, two kinds of detections are synchronously carried out, detect more precisely fast, save time and manpower, enhance productivity.And more short-circuit-type is distinguished on refinement ground, so that the battery differentiated treatment of two kinds of different short circuits, for example, can further to the battery of aluminum plastic film short circuit, repack, greatly reduce cost and the potential safety hazard of production battery core, improve yield, avoid waste, improved production competitive power.
It should be noted that; the present invention is not limited to above-mentioned embodiment, and according to creative spirit of the present invention, those skilled in the art can also make other variations; the variation that these are done according to creative spirit of the present invention, within all should being included in the present invention's scope required for protection.
