The working process of the screening apparatus 100 is as follows:

firstly, the ejector 22 pushes a plurality of components 200 at the bottom of the bin 21 into the feed runner 11, the ejector 25 moves towards the components 200 supported by the ejector 22 under the drive of the ejector drive 24 so as to push the components 200 higher than the preset spacing 251 into the bin 21, the feed 23 moves along the extending direction of the feed runner 11 and pushes the components 200 into the distributing runner 12 from the feed runner 11, the distributing detector 33 detects that the number of the components 200 in the transmission groove 121 reaches the preset number, and the distributing detector 33 sends an electric signal to the feed assembly 20 so as to stop the feed assembly 20 from providing the components 200;

then, the spacer driving part 311 drives the plurality of spacer parts 313 to synchronously move close to the transmission groove 121 through the linkage part 312, so that the plurality of spacer parts 313 separate the plurality of elements 200 in the transmission groove 121, and the material stop 34 moves towards the element 200 at the lowest layer and the element 200 adjacent to the element in the transmission groove 121, so as to separate the element 200 at the lowest layer and the element 200 adjacent to the element in the transmission groove 121, and avoid material clamping between the two adjacent elements 200;

next, the screening driving part 413 drives the screening part 414 to move below the communicating groove 123, the material distributing member 32 receives the element 200 at the lowest layer in the transmission groove 121 through the penetrating groove 321, and conveys the element 200 into the accommodating space 412 through the communicating groove 123, the screening detecting member 42 detects whether the element 200 in the accommodating space 412 maintains the preset orientation, and sends the detection information obtained thereby to the screening member 41 through an electric signal;

finally, the screening member 41 screens the element 200 with the preset orientation into the main flow channel 132 or screens the element 200 not in the preset orientation into the split flow channel 133 based on the detection information, and the air blowing member 43 blows the element 200 moving to the junction of the split flow channel 133 and the arc-shaped flow channel 134 into the arc-shaped flow channel 134, so that the element 200 is adjusted to the preset orientation under the guidance of the arc-shaped flow channel 134, and the screening of the element 200 conforming to the preset orientation and the adjustment of the orientation of the element 200 not in the preset orientation to the preset orientation are realized in the transmission process of the element 200.
