The specific implementation process is as follows: during the use, the diode through welding encapsulation is stacked in feeder hopper 22, step motor drive fortune material wheel 19 rotates, the pin of the diode in the in-process feeder hopper 22 falls into one by one in the clearance between two fortune material teeth 17 just right with feeder hopper 22 in proper order, because fortune material wheel 19's wheel face is preceding, the back both sides all have fortune material tooth 17, make the pin that the diode is in both ends on fortune material wheel 19 by the state of fortune material tooth 17 joint, fortune material wheel 19 rotates the in-process fortune material tooth 17 and drives the pin of diode and then drive the diode and remove along fortune material wheel 19's wheel face, the baffle prevents that diode and pin from droing from fortune material wheel 19. When the diode moves to the right end of the material conveying wheel 19 along with the material conveying teeth 17, the diode is contacted with the conductive probes 26 extending out of the baffle, two pins of the diode are respectively contacted with the two conductive probes 26 from two sides of the material conveying wheel 19 at the same time, and current emitted from the power supply 4 enters the diode through the conductive probes 26. If the diode is intact and the conducting direction is consistent with the current direction, a loop formed by the power source 4, the conductive probe 26, the diode, the discharging cylinder 2 and the electromagnet 24 is conducted, the electromagnet 24 is electrified to generate a magnetic field to repel and push away the magnet 23 on the discharging plate 5, so that the discharging opening is opened, meanwhile, the discharging cylinder 2 drives the discharging rod to move towards the discharging opening, and the material pushing plate 3 on the discharging rod pushes out the pin of the diode from between the material conveying teeth 17, so that the diode is discharged from the discharging opening and falls on the conveyor belt 6.
In another case, after the current from the power source 4 enters the diode through the conductive probe 26, if the diode is damaged or is placed in an extreme wrong position so that the conducting direction is opposite to the current direction, the loop formed by the power source 4, the conductive probe 26, the diode, the discharging cylinder 2 and the electromagnet 24 cannot be conducted, the electromagnet 24 and the discharging cylinder 2 are not electrified and do not work, when the stepping motor rotates again after being intermitted, the material conveying wheel 19 continues to drive the diode to move downwards, and then the diode which moves to the discharging opening continuously repeats the process.
When the diode which is not discharged from the discharge opening continues to move to the material leakage opening along with the material conveying wheel 19, the material pushing cylinder 9 synchronously acts to push the material pushing rod to the supporting plate, the supporting rod and the ejector rod 7 are driven to act in the process, the ejector rod 7 pushes the push rod 14 to overcome the action of the pressure spring 16 through the wedge surface 15 to move downwards, the material pushing plate 3 at the bottom end of the push rod 14 pushes the pin of the diode which is positioned above the material leakage opening, and the diode is separated from the material conveying wheel 19 and pressed into the guide pipe and the reversing piece 10.
