As shown in fig. 3, a fourth position detecting sensor 94 is installed at an upstream end of the second conveying unit 2, and a fourth detecting end of the fourth position detecting sensor 94 is disposed toward the second conveying unit 2. The fourth position detecting sensor 94 preferably employs a third correlation sensor, the transmitting end and the receiving end of the third correlation sensor are respectively located on two opposite sides of the second transmission chain, and when the jig 4 is placed on the second conveying unit 2, the downstream end of the jig 4 is just located between the transmitting end and the receiving end of the third correlation sensor along the second conveying direction, so that the receiving end of the third correlation sensor cannot receive the signal sent by the transmitting end of the third correlation sensor. The fourth position detecting sensor 94 is used for detecting whether there is a jig 4 in the third preset position at the upstream end of the second conveying unit 2, so as to prevent the empty jig 4 from overlapping on the second conveying unit 2 when the first transplanting unit 3 transfers the empty jig 4 on the first conveying unit 1 to the second conveying unit 2, and further prevent the jig 4 from falling off from the second conveying unit 2.

The operation of the feeding device 8 is briefly described below with reference to fig. 1 to 15:

when the first conveying unit 1 conveys the jig 4 to the second preset position, the first clamping unit clamps the jig 4. Then, the second driving mechanism 62 and the third driving mechanism 63 of the turnover unit 6 cooperate to drive the second clamping mechanism 61 to rotate to the first turnover position, so that the second clamping mechanism 61 moves to the jig 4, so that the second clamping mechanism 61 will clamp the corresponding electronic component on the jig 4, and subsequently, the second driving mechanism 62 and the third driving mechanism 63 cooperate to drive the second clamping mechanism 61 to rotate to the second turnover position, so as to turn over the clamped electronic component by 180 °.

In addition, when the next fixture 4 of the fixture 4 moves to the first preset position, the second position detecting sensor 92 sends a detection signal to the control system, so that the control system controls the second clamping unit 52 to clamp the next fixture 4, and the clamping of the next fixture 4 is not released until all the electronic components on the fixture 4 are taken out and move out of the taking station.

Next, the fifth driving mechanism 84 of the calibration tool 8 drives the sliding table 8411 to move toward the carrier table 82 through the first driving module 8412, so that the first positioning claw 831 and the second positioning claw 832 are respectively engaged with the first limiting portion 84113 and the second limiting portion 84115 of the sliding table 8411, and meanwhile, the second driving assembly 842 drives the third positioning claw 833 to move back to the second positioning claw 832, at this time, the first positioning claw 831, the second positioning claw 832 and the third positioning claw 833 are in an open state (as shown in fig. 5).

Next, the fourth driving mechanism 72 of the second transplanting unit 7 drives the third clamping mechanism 71 to move to the jig 4 at the material taking station to clamp the electronic component, and then the fourth driving mechanism 72 drives the third clamping mechanism 71 to move to the bearing table 82 of the calibration fixture 8, so that the third clamping mechanism 71 places the clamped electronic component on the bearing table 82.

Next, the fifth driving mechanism 84 of the calibration tool 8 is reset by the first driving module 8412, so that the sliding table 8411 moves back to the carrying table 82 under the action of the elastic potential energy of the third elastic element 8415, the first claw end 8311 of the first positioning claw 831 and the second claw end 8321 of the second positioning claw 832 gradually move towards the electronic component, and the second driving module 842 drives the third positioning claw 833 to move towards the electronic component, so that the first positioning claw 831, the second positioning claw 832 and the third positioning claw 833 are switched to the closed state. When the first fitting portion 8312 of the first positioning claw 831 is out of contact with the first fitting surface of the sliding table 8411, the electronic component abuts against the reference block 821, and the first claw end 8311 abuts against the electronic component; when the second fitting portion 8322 of the second positioning pawl 832 is out of contact with the second fitting surface of the slide table 8411, the second pawl end 8321 abuts against the self-reference block 821. When the electronic component abuts against the reference block 821, the first claw end 8311, the second claw end 8321 and the third claw end 8331, respectively, the position calibration and the orientation of the electronic component are completed (as shown in fig. 2).

Subsequently, the third clamping mechanism 71 grabs the electronic component on the carrier table 82 after the position calibration and orientation are completed, and then the first driving module 8412 of the fifth driving mechanism 84 drives the sliding table 8411 to move towards the carrier table 82 again, so that the first positioning claw 831, the second positioning claw 832 and the third positioning claw 833 are in an open state again.

When the first positioning claw 831, the second positioning claw 832 and the third positioning claw 833 are switched to the open state, the fourth driving mechanism 72 of the second transplanting unit 7 drives the third clamping mechanism 71 to move to the next-stage device of the feeding device 100, and places the electronic component on the second jig of the next-stage device.

Then, the first clamping unit 51 releases the clamping of the jig 4, so that after the first conveying unit 1 controls the jig 4 to move forward by the preset distance, the first clamping unit 51 re-clamps the jig 4, so that the overturning unit 6 takes away the next group of electronic components on the jig 4, and the related steps are repeated until all the electronic components on the jig 4 are taken away.

When all the electronic components on the jigs 4 are taken away, the first conveying unit 1 transfers the jigs 4 to the first transplanting unit 3, so that the first transplanting unit 3 transfers the empty jigs 4 to the second conveying unit 2. Meanwhile, the second clamping unit 52 releases the clamping of the subsequent jig 4, so that the first conveying unit 1 transfers the subsequent jig 4 to the material taking station, and repeats the relevant steps.

In summary, the feeding device provided by the utility model can orderly supply electronic components and prevent the electronic components from being damaged in the feeding process.
