When the turnover drum 50 rotates to align the two ends of the through hole 501 with the main trough 40 and the connecting groove 41, the stop lever 512 moves to the rear end of the guide lever 53, so that the horizontal height of the baffle plate 51 is unchanged, the side of the turnover drum 50 where the baffle plate 51 is arranged rotates upwards, the distance between the axis of the stop lever 512 and the axis of the turnover drum 50 is gradually increased, so that the baffle plate 51 is drawn out of the through hole 501, and the retraction spring 52 is in a stretching state.
As shown in fig. 15 and 17, when the two ends of the through hole 501 are aligned with the main trough 40 and the connecting trough 41 respectively, the top surface of the baffle 51 is lower than the bottom surface of the through hole 501, and the upper section of the baffle 51 is completely hidden in the solid body of the turnover drum 50, so that the triode in the main trough 40 can enter the through hole 501, and the triode can be smoothly conveyed from the through hole 501 to the connecting trough 41.
The structure uses the rotation of the turnover cylinder 50 to drive the baffle 51 to move, and uses the guide rod 53 to limit the moving range of the baffle 51, thereby realizing the linkage control between the baffle 51 and the turnover cylinder 50.
Preferably, the stop lever 512 is rotatably sleeved with a circular tube, and the circular tube is in rolling contact with the bottom surface of the guide rod 53 to reduce the friction resistance.

Specifically, the bottom surface of the through-hole 501 is inclined downward toward one side of the connection groove 41, thereby forming a tapered structure.
As shown in fig. 15, when one end of the through-hole 501 facing the main trough 40 is aligned with the main trough 40, the bottom surface of the other end of the through-hole 501 is lower than the conveying surface of the connecting groove 41, and the outer wall of the inversion cylinder 50 blocks the outlet of the inversion trough 30.
As shown in fig. 17, when the bottom surface of the through hole 501 facing one end of the connecting groove 41 is flush with the conveying surface of the connecting groove 41, the transistor in the through hole 501 can be input into the connecting groove 41, and at this time, the distance between the top surface of the through hole 501 facing one end of the main material groove 40 and the conveying surface of the main material groove 40 is smaller than the thickness of the transistor, so as to prevent the transistor in the main material groove 40 from continuously entering the through hole 501, and further prevent the transistor in the main material groove 40 from being blocked in the through hole 501 in the process that the turning cylinder 50 rotates to connect the through hole 501 with the turning material groove 30. And at this time, the outer wall of the overturning barrel 50 blocks the outlet of the overturning trough 30 to prevent the triode from falling.
As shown in fig. 18, when the through hole 501 is aligned with the outlet of the inversion bin 30, the outer wall of the inversion bin 50 blocks the main bin 40 to prevent the triodes in the main bin 40 from entering the through hole 501 at the same time.
In use, if a triode in the through hole 501 needs to be fed into the connecting groove 41, the through hole 501 needs to be rotated upward by a predetermined angle toward one end of the connecting groove 41, so that the bottom surface of the through hole 501 is flush with the conveying surface of the connecting groove 41. At this time, the height distance between the top surface of the through hole 501 facing one end of the main material tank 40 and the conveying surface of the main material tank 40 is reduced, and the distance is smaller than the thickness of the triode, so that the triode on the main material tank 40 is prevented from continuously entering the through hole 501. After the triodes in the overturning trough 30 enter the through hole 501, only one end of the through hole 501 facing the overturning trough 30 is required to be lowered to a state that the bottom surface of the through hole 501 is flush with the conveying surface of the connecting groove 41, the triodes in the through hole 501 can smoothly enter the connecting groove 41, and the triodes in the main material groove 40 still cannot directly enter the through hole 501. The rotation direction of the flipping cylinder 50 can be controlled to selectively make the through hole 501 receive the triode conveyed by the main trough 40 or the flipping trough 30. This structure is configured such that the through-hole 501 does not interfere with the communicating between the reversing chute 30 and the main chute 40 by the tapered structure of the through-hole 501.
Preferably, as shown in fig. 2 and 13, a lifting plate 43 is disposed at the end of the connecting groove 41 perpendicular to the conveying surface, a lever 431 is disposed at the lower end of the lifting plate 43 facing the rotating cylinder 60, and the lever 431 is located below the connecting groove 41. The guiding groove has been seted up along the circumference to the outer wall of rotatory section of thick bamboo 60 hypomere, and guiding groove is located in the slip of driving lever 431, and the guiding groove includes a pair of arc groove 621 of downwarping, and arc groove 621 corresponds the below of locating through-hole 61 both ends opening part respectively, communicates through horizontal groove 622 between the arc groove 621.
As shown in fig. 2 and 16, when the two ends of the through hole 61 are aligned with the connecting groove 41 and the output groove 42, respectively, the shift lever 431 is at the lowest point of the arc groove 621, and at this time, the top surface of the elevating plate 43 is lower than the conveying surface of the connecting groove 41.
When the shift lever 431 is located at a position other than the lowest point of the circular arc groove 621, the top surface of the lifting plate 43 protrudes upward beyond the conveying surface of the connecting groove 41, so as to block the triode in the connecting groove 41 from being conveyed backwards continuously in the rotation process of the rotary drum 60. As shown in fig. 14, at this time, the shift lever 431 is located in the horizontal groove 622, the upper section of the lifting plate 43 protrudes out of the top surface of the connecting groove 41 to block the transistor in the connecting groove 41 from being continuously transported until the rotating cylinder 60 rotates to the through hole 61 to communicate with the connecting groove 41 and the output groove 42, the transistor in the connecting groove 41 can not continuously enter the through hole 61, and the rotating cylinder 60 can be provided with a proximity switch to detect the position of the transistor in the through hole, so as to serve as a basis for controlling the rotation timing.
More specifically, as shown in fig. 9, 14 and 16, two detecting sensors 44 are disposed on the same side of the end of the connecting slot 41 along the conveying direction for detecting the pin-in-place signal of the transistor, the detecting sensors 44 may be proximity switches or photoelectric sensors, and the distance between the two detecting sensors 44 is the same as the distance between the two pins on the same side of the transistor. The triode facing the side provided with the detection sensor 44 on the single pin of the connecting groove 41 directly enters the output groove 42 through the through hole 61, and after the triode facing the side provided with the detection sensor 44 on the two pins enters the through hole 61, the triode is discharged into the output groove 42 after the rotary cylinder 60 rotates 180 degrees. The detecting sensor 44 is arranged at the position of the last buffer triode of the connecting groove 41, the left and right orientation of the pins can be judged only when the two detecting sensors 44 simultaneously detect pin signals, and after the triode enters the through hole 61, the rotating cylinder 60 rotates 180 degrees, so that the pins of the triode are changed in orientation, and the pin orientation of the triode is consistent.
The foregoing is only a preferred embodiment of the present invention and is not intended to be exhaustive or to limit the invention. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention.
