[0037] In the present invention, after the vibrating disk transfers the fisheye pins to the feeding end of the direct vibrating feeder 2, the direct vibrating feeder 2 works to drive the fisheye pins to move continuously to the right until the fisheye pins reach the position of the conductive component 31, the direct vibrating feeder 2 stops working, and the conductive component 31 performs a conductivity test on the fisheye pins; if the test is qualified, the direct vibrating feeder 2 will work again, driving the fisheye pins to move to the right; if the test is unqualified, the separating component 32 works to screen out and collect the fisheye pins that have failed the test from the direct vibrating feeder 2; when the fisheye pins that have passed the conductivity test move to the discharging end of the direct vibrating feeder 2, the supporting driving component works to drive the moving component to move, so that the fisheye pins can complete the discharge requirements of multiple rows under the condition that only one direct vibrating feeder 2 is needed;

[0042] The material moving assembly includes a sliding plate 43 and a fixing slot 44. The output end of the double-stroke cylinder 41 is fixedly connected to the lower end of the sliding plate 43. The sliding plate 43 is provided with a plurality of fixing slots 44 having the same shape and size as the lower end of the fisheye pin. The fixing slots 44 are evenly distributed linearly and at equal intervals on the sliding plate 43.

[0043] In the present invention, after the vibrating plate transfers the fisheye pin to the feeding end of the direct vibrating feeder 2, the direct vibrating feeder 2 works to drive the fisheye pin to move to the right. When the fisheye pin moves to the screening station, the direct vibrating feeder 2 stops working. At this time, the fisheye pin is in the bearing groove 327 on the front side of the bearing support block 323. Then the first cylinder 312 works to drive the conductive plate 313 to move downward until the lower end of the conductive plate 313 touches the upper end of the fisheye pin; the second cylinder 315 works to drive the conductive column 314 to move upward until it reaches the conductive column 314. The upper end of the fisheye pin touches the lower end of the fisheye pin; then the conductivity test can be carried out; if the test is qualified, the direct vibration feeder 2 works to drive the fisheye pin to continue to move to the right; if the test is unqualified, the third cylinder 322 works to drive the supporting block 323 to move to the right along the sliding groove 328 until the supporting groove 327 on the rear side of the supporting block 323 is aligned with the next fisheye pin, and the fourth cylinder 324 on the front side works to drive the pin 325 to move to the left, pushing the unqualified fisheye pin out of the supporting groove 327 and dropping it into the storage box 326 on the front side;

[0045] When the qualified fisheye pin passes through the discharge end of the direct vibration feeder 2 and enters the fixed groove 44 on the rear side of the sliding plate 43, the double-stroke cylinder 41 then drives the sliding plate 43 to move backward along the guide rod 45. At this time, the right end of the fisheye pin is fixed by the inner wall of the fixed groove 44, and the left end is in contact with the right wall of the baffle plate 42, until the fixed groove 44 in the middle of the sliding plate 43 is aligned with the discharge end of the direct vibration feeder 2. The next fisheye pin enters the fixed groove 44, and the above steps are repeated until multiple fixed grooves 44 on the sliding plate 43 are filled. The fisheye pin on the sliding plate 43 can then be removed by the mechanical claw; the double-stroke cylinder 41 is then reset, and the fisheye pins can continue to be filled in the fixed groove 44; by repeating the above steps, continuous fisheye pin feeding operation can be achieved.
