[specific embodiment]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 1 is the structural representation of spot welding error prevention device in an embodiment.This spot welding error prevention device comprises: detect pedestal 100, controller 200 and alarm 300.
Detect pedestal 100 and be fixed on mash welder, for carrying and obtain the modes of emplacement of assembled battery 10.
Assembled battery 10 is placed on while detecting pedestal 100 enterprising spot welding, corresponding a kind of modes of emplacement separately, and modes of emplacement is unique and fixing.If modes of emplacement correctly spot welding can not make a mistake, if modes of emplacement mistake spot welding meeting make a mistake.
Assembled battery 10 is placed on and detects on pedestal 100 with different modes of emplacements, and sense of current during electric discharge is different, detects pedestal 100 by detecting the sense of current of assembled battery 10 when placed thereon, obtains the modes of emplacement of assembled battery 10.
In this embodiment, detecting pedestal 100 is rectangular susceptor, offers a plurality of fixing holes 110 on it, for detection pedestal 100 is threaded connection to part, is fixed on mash welder.Detect on pedestal 100 and be provided with the first test column 120 (post A) and the second test column 130 (post B).Between the first test column 120 and the second test column 130, distance is adjustable according to the number of batteries of assembled battery 10.The first test column 120 is connected with controller 200 by wire separately with the second test column 130, while being placed on detection pedestal 100 for assembled battery 10, contacts respectively with the electrode adaptation of 10 liang of end-cells of assembled battery.The point capillary of mash welder and the first test column 120 over against, spot welding is carried out spot welding for the battery being placed on the first test point 120.
Assembled battery 10 is placed on and detects on pedestal 100 with different modes of emplacements, and when electrode contacts with the second test column 130 with the first test column 120 respectively, the sense of current is respectively corresponding to the first test column 120 to second test columns 130 or a kind of in the second test column 130 to first test columns 120, for example, during spot welding negative outside wire, if modes of emplacement is correct, the sense of current is by the first test column 120 to second test columns 130, during spot welding positive outside wire, if modes of emplacement is correct, the sense of current is by the second test column 130 to first test columns 120, thereby the sense of current while being placed on detection pedestal 100 by detecting assembled battery 10, obtain the modes of emplacement of assembled battery 10.
Controller 200, for receiving and judging that whether assembled battery 10 modes of emplacements are correct, is controlled mash welder and is quit work when modes of emplacement mistake.Further controlling alarm 300 reports to the police.
Fig. 2 is the structural representation of an embodiment middle controller.In this embodiment, controller 200 receives and judges that according to the sense of current of assembled battery 10 whether assembled battery 10 modes of emplacements are correct, when modes of emplacement mistake, control mash welder and quit work, comprising: diode 210, two voltage comparison unit 220, triode unit 230 and magnetic valve 240.
Magnetic valve 240 is connected with mash welder cylinder, control cylinder work.
Diode 210 has the unidirectional general character, is connected with the second test column 130 with the first test column 120, whether correctly detects the sense of current.In this embodiment, utilize the unidirectional general character of diode 210, according to the different demands of spot welding positive pole or negative pole, the cut-off direction of setting driving lever 211 setting diodes 210 by cut-off is the correct corresponding sense of current of assembled battery 10 modes of emplacement.If assembled battery 10 senses of current make diode 210 cut-offs, assembled battery 10 modes of emplacements are correct; If diode 210 conductings, assembled battery 10 modes of emplacement mistakes.For example, during spot welding negative outside wire, when modes of emplacement is correct, the sense of current is by the first test column 120 to second test columns 130, by cut-off, sets cut-off direction that driving lever 211 sets diodes 210 for by the first test column 120 to second test columns 130.During spot welding positive outside wire, when modes of emplacement is correct, the sense of current is by the second test column 130 to first test columns 120, by cut-off, sets cut-off direction that driving lever 211 sets diodes 210 for by the second test column 130 to first test columns 120.
Two voltage comparison units 220 are in sense of current mistake, and during diode 210 conducting, output low level (take 1V as reference voltage) is given triode unit 230.
Triode unit 230 receives low level, takes to control magnetic valve 240 and disconnects, and cylinder is quit work, and control point welding machine quits work.Further, control warning 300 and report to the police, thereby prevent that spot welding mistake from occurring.
Alarm 300 is arranged on controller 200 enclosure interior, accepts the control of controller 200 and carries out alarm operation.In this embodiment, alarm 300 adopts loudspeaker, and is connected with triode unit 230.
When this spot welding error prevention device carries out work, spot welding assembled battery 10 negative outside wires (being the negative pole of spot welding battery 11) of take are example, the cut-off direction of setting diode 210 is by the first test column 120 to second test columns 130, battery in assembled battery 10 11 positive poles are contacted with the first test column 120, the positive pole of battery 13 contacts with the second test point 130, and some capillary carries out spot welding over against the negative pole of battery 11.If modes of emplacement is correct, the sense of current of assembled battery 10 is by the first test column 120 to second test columns 130, diode 210 cut-offs, and spot welding is carried out in the normal work of mash welder; For example, if (, assembled battery 10 integral body put back modes of emplacement mistake, and battery 11 contacts with the second test column 130 with the first test column 120 respectively with battery 13 negative poles; Or only battery 11 puts back or leak source weldering, can not conducting in assembled battery 10 etc.), diode 210 conductings, controller 200 control point welding machines quit work or are reported to the police by alarm 300, thereby effectively prevent the generation of spot welding mistake, replace manual operation, guarantee the integrality of brace spot welding and reduce the attention rate that detects operation, reduce cost of labor.
In other embodiments, controller 200 is not connected with mash welder, is only connected with alarm 300, at 200 control alarms 300 of modes of emplacement mistake Time Controller, reports to the police, and notifies operating personnel, prevents that spot welding mistake from occurring.
In addition, in the time of also can being placed on detection pedestal 100 according to assembled battery, the electromotive force on the first test column 120 and the second test column 130, or the electrical potential difference between the first test column 120 and the second test column 130 judges that whether assembled battery modes of emplacement is correct.
Above-mentioned spot welding error prevention device, obtain the modes of emplacement of assembled battery, judge that whether assembled battery modes of emplacement is correct, when modes of emplacement mistake, control mash welder and stop spot welding, thereby effectively prevent the generation of spot welding mistake, guaranteed normal use and the safety of assembled battery, replace manual operation, greatly improve efficiency, guaranteed the integrality of spot welding, reduced the attention rate and the production cost that detect operation.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
