When bilgeway 21 and lower floor's slide plate 22 move toward one another; The two pins of electronic component (like LED) gets into pin adjustment folder 32, if the distance between the two pins is excessive, then in bilgeway 21 and lower floor's slide plate 22 motion processes; Because the opening of pin adjustment folder 32 is inwardly shunk by opening part gradually; Therefore pin adjustment folder 32 can push away two pins closely relatively, makes the distance between the two pins reach the regulation requirement, is convenient to the plug-in mounting of subsequent handling.
After electronic component is accomplished and is cut pin; Left side driving mechanism and the action of right driving mechanism; Driving left skateboard 6 and right slide plate 7 advances forward to advancing slip first crossbeam 3, second crossbeam 4, the 3rd crossbeam 5 of driving thus; Workpiece gripping head on first crossbeam 3 continues the gripping electronic component, and the workpiece gripping head on second crossbeam 4 opens, and the electronic component of cutting pin has been accomplished in gripping on cutter mechanism.
Left afterwards driving mechanism and the action of right driving mechanism; Drive left skateboard 6 and right slide plate 7 backward rollback drive first crossbeam 3, second crossbeam 4, the 3rd crossbeam 5 rollback backward thus; Workpiece gripping head on second crossbeam 4 brings to electronic component and unclamps electronic component after polarity identification turns to detent mechanism; Electronic component carries out polarity identification and carries out rotational positioning, and the workpiece gripping head on first crossbeam 3 brings to cutter mechanism with electronic component once more and cuts pin simultaneously.The principle that polarity identification turns to detent mechanism to carry out polarity identification and rotational positioning is: the expanding mechanism action is opened first utmost point pawl 38 and second utmost point pawl 39; Electronic component gets between first utmost point pawl 38 and second utmost point pawl 39; Expanding mechanism resets and makes win utmost point pawl 38 and second utmost point pawl 39 press from both sides once more then, makes two pins of electronic component be attached to respectively on first contact and second contact.If the anodal pin of electronic component is connected with positive source brace 34 through first engagement shaft 45 (or second engagement shaft), first lead (or second lead), first contact stud 43 (or second contact stud); The negative pole pin of electronic component is connected with power cathode brace 35 through second engagement shaft 46 (or second engagement shaft), second lead (or first lead), second contact stud 44 (or first contact stud); Thereby then form the loop through the conducting of electronic component between first contact and second contact; The direction of two pins of electronic component is correct at this moment; In the loop, there is electric current to pass through; Thereby the industrial computer to the outside sends signal, keeps rotating shaft 36 and does not rotate; Opposite like situation; The anodal pin that is electronic component is connected with power cathode brace 35; The negative pole pin of electronic component is connected with positive source brace 34; Then do not form the loop, industrial computer is received after the no current telecommunications rotating shaft of instruction drive mechanism and is rotated, thereby makes the transposition that contacts of the contact stud 43 of winning, second contact stud 44 and positive source brace 34, power cathode brace 35; The effect that thereby the anodal pin that reaches electronic component once more is connected with positive source brace 34, the negative pole pin of electronic component is connected with power cathode brace 35, so that two pins of electronic component is in the right direction.
After accomplishing polarity identification and turning to the location; Left side driving mechanism and the action of right driving mechanism; Driving left skateboard 6 and right slide plate 7 advances forward to advancing slip first crossbeam 3, second crossbeam 4, the 3rd crossbeam 5 of driving thus; Workpiece gripping head on second crossbeam 4 is accomplished the electronic component of cutting pin once more on the gripping cutter mechanism, and the workpiece gripping head on first crossbeam 3 is the gripping electronic component once more, and the workpiece gripping head on the 3rd crossbeam 5 then gripping is accomplished polarity identification and turned to the electronic component of location.Left afterwards driving mechanism and right driving mechanism move again; Drive left skateboard 6 and right slide plate 7 backward rollback drive first crossbeam 3, second crossbeam 4, the 3rd crossbeam 5 rollback backward thus; Workpiece gripping head on the 3rd crossbeam 5 will be accomplished the follow-up conveyer that electronic component that the polarity identification machine turns to the location is delivered to balladeur train the place ahead; The electronic component that workpiece gripping head on second crossbeam 4 is cut pin with completion is delivered to polarity identification and is turned to detent mechanism to carry out the polarity identification machine to turn to the location; Workpiece gripping head on first crossbeam 3 is delivered to cutter mechanism with electronic component and is cut pin, thereby accomplishes a circulation.Constantly repeat the course of work that above-mentioned circulation has just formed the utility model.
