When above-mentioned steps S6 is judged to be YES, enters step S7 and judge adsorbed state whether normally (whether can on printed circuit board (PCB) 3, carry element).This judgement is carried out according to above-mentioned video camera 20 captured images, or the image of taking from suction nozzle 17 adsorbed element belows with video camera 24 according to component recognition carries out.
According to the result of determination of step S6, S7 and unusual number of times etc., from CASE1 to 4 shown in Figure 8, select abnormality processing.
That is, when suction nozzle 17 is not held element (when step S6 is judged to be NO), from CASE1 to 3, select one (step S8).
Herein, CASE1 is that reprogramming is judged to be unusual suction nozzle 17 to stop using, and remaining normal suction nozzle 17 is installed in a plurality of suction nozzles 17 of use head unit 6 equipments, element is assigned on the normal suction nozzle 17 once more, and then proceeds the running of fitting machine.CASE2 changes standby suction nozzle to be judged to be unusual suction nozzle 17 by automatic or manual, and then remains in operation.In addition, CASE3 is the Correction and Control data, at being judged to be unusual suction nozzle 17, changes its head descending stroke when absorptive element or installation elements, or reduces decrease speed, continues to carry out the running of fitting machine then.
The processing selecting of step S8 can preestablish a certain situation, also can select according to unusual frequency n.When selecting according to unusual frequency n, for example, set the 1st, the 2nd threshold values n1, n2 according to the relation of n1＜n2＜nx in advance, select CASE3 during less than the 1st threshold values n1, select CASE2 in the time of between the 1st threshold values n1 and the 2nd threshold values n2, select CASE1 when surpassing the 2nd threshold values n2.
In addition, suction nozzle 17 is held element (when step S6 is judged to be YES) and is adsorbed posture just often (when step S7 is judged to be YES), selects one (step S9) from CASE3,4.
Herein, CASE3 as mentioned above, CASE4 reclaims or element that discarded this suction nozzle 17 is adsorbed.
The processing selecting of step S9 can preestablish a certain situation, also can select according to unusual frequency n.When selecting, for example, set threshold values, select CASE3 during less than this threshold values, select CASE4 when surpassing threshold values less than boundary value nx according to unusual frequency n.
In addition, suction nozzle 17 is held element (when step S6 is judged to be YES) and absorption posture when undesired (when step S7 is judged to be NO), carries out the processing of CASE4.
In addition, above-mentioned steps S4 judges when unusual frequency n surpasses predefined boundary value nx, when driving alarm display part 37 and carry out wrong the demonstration, stops the running (step S11) of fitting machine.
Device according to aforesaid present embodiment, can by video camera take from the side the suction nozzle top ends and near, according to image, check the overhang of suction nozzle top ends 17b with respect to suction nozzle main body 17a, if not being positioned at normal range (NR), it then is not judged to be generation unusually.Therefore; because suction nozzle 17 sucks dust or paste scolder and wearing and tearing etc. cause pooling feature low; make the top ends 17b of the suction nozzle behind absorptive element or the installation elements not return normal outstanding state, shown in Fig. 5 (b), be when submerging state, can make practical judgement this.
Taking place above-mentionedly when unusual, by changing the descending stroke or the decrease speed of suction nozzle 17, the reduction of pooling feature is being compensated.In addition, also replaceable suction nozzle 17 is eliminated unusually.Perhaps, be judged to be unusual suction nozzle 17, use remaining normal suction nozzle 17, can avoid correctly to adsorb or to install electronic component by stopping using.In addition, when suction nozzle 17 was held element, if unusual increased frequency, then pooling feature can reduce greatly, might cause damage to element when mounted, therefore can carry out the recovery, discarded etc. of element.And then when unusual number of times significantly increases, can stop the running of fitting machine.
So, being at suction nozzle does not have under the normal outstanding abnormal conditions, and the state and the unusual number of times etc. of fitting machine are taked treatment measures according to this moment, suppresses the low caused element damage of pooling feature of suction nozzle and the generation of problem such as bad is installed.
