[0028] The transmission mechanism includes a dividing disk 5. The surface of the dividing disk 5 is circumferentially provided with a plurality of card slots 6 for workpieces to enter. A servo motor 7 is fixedly installed on the surface of the funnel 3. A through hole is provided on the surface of the funnel 3, and a rotating rod 8 is rotatably installed in the through hole.

[0029] First, the diodes to be processed are all placed in the funnel 3. The diodes located in the funnel 3 will accumulate at the bottom of the funnel 3 along the inner wall of the inclined funnel 3, and some diodes will be located in the card slots 6 on the side wall of the dividing disk 5. Then, at this time, the servo motor 7 is started. The output shaft of the servo motor 7 will drive the driving synchronous pulley 10 to rotate. Then, under the driving action of the synchronous belt 11, the driven synchronous pulley 9 will drive the rotating rod 8 and the dividing disk 5 to rotate. The pins of the diodes located in the plurality of card slots 6 will sequentially contact the guide plate 29 and be guided by the guide plate 29 to the electric control scissors 4. The electric control scissors 4 will cut the pins of the diodes, and the cut diodes will then fall into the discharge track 12.

[0030] Inductive switches 13 and photoelectric sensors 14 are respectively fixedly installed on the surfaces of the funnel 3 and the discharge track 12. An induction ring 15 is fixedly sleeved on the driven synchronous pulley 9. A support column 16 is fixedly installed on the surface of the induction ring 15. The inductive switch 13 is located on the rotation path of the support column 16.

[0031] When the support column 16 on the rotating induction ring 15 rotates to the inductive switch 13, it plays a role in detecting the movement and counting of the driven synchronous pulley 9, while the photoelectric sensor 14 located below is used to sense the state of the product during discharging.

[0032] An oil cavity 17 is provided inside the rotating rod 8. A storage oil tank 18 is provided on the surface of the funnel 3. One end of the rotating rod 8 is provided with an oil supply assembly for supplying the lubricating oil located in the storage oil tank 18 into the oil cavity 17. Symmetrically arranged oil outlets 23 communicating with the oil cavity 17 are provided on the surface of the rotating rod 8 inside the through hole. The oil supply assembly includes a reciprocating lead screw 28, a sliding rod 19 threadedly sleeved on the reciprocating lead screw 28, a hollow rod 20 with a closed end, and a piston rod 21 sealingly and slidably inserted into the hollow rod 20.

The outer wall of the rotating ring 24 is in sliding sealing contact with the wall of the through port. An oil outlet pipe 25 is fixedly installed at the closed end of the hollow rod 20. The end of the oil outlet pipe 25 away from the hollow rod 20 passes through the rotating ring 24. The hollow rod 20 is connected to the storage oil tank 18 through an oil inlet pipe 26.

The sliding rod 19 is restricted from rotating by a restricting component. The restricting component includes a restricting rod 27 horizontally and fixedly installed on the surface of the funnel 3. The sliding rod 19 is slidably sleeved on the restricting rod 27.

[0033] When the rotating rod 8 is rotating, the reciprocating lead screw 28 will also rotate together at this time. The sliding rod 19 threadedly sleeved on the reciprocating lead screw 28 will drive the piston rod 21 to perform a horizontal reciprocating movement under the restricting action of the restricting rod 27. The volume inside the hollow rod 20 will continuously change from small to large and then from large to small. When the volume inside the hollow rod 20 becomes larger, the pressure decreases, and the lubricating oil located in the storage oil tank 18 will enter the hollow rod 20 from the oil inlet pipe 26. When the volume inside the hollow rod 20 becomes smaller, the pressure will increase, and the lubricating oil located inside the hollow rod 20 will enter the oil cavity 17 from the oil outlet pipe 25, and then flow out from the multiple oil outlets 23 and act on the contact surface between the rotating rod 8 and the through hole, playing a lubricating effect to prevent excessive dust between the contact surface of the rotating rod 8 and the through hole, resulting in a large frictional force and affecting the rotation of the rotating rod 8, the driven synchronous pulley 9, and the dividing disc 5.

[0034] In the present utility model, first, the diodes to be processed are all placed in the funnel 3. The diodes located in the funnel 3 will accumulate at the bottom of the funnel 3 along the inner wall of the inclined funnel 3, and some diodes will be located in the card slots 6 on the side wall of the dividing disc 5. Then, at this time, the servo motor 7 is started. The output shaft of the servo motor 7 will drive the driving synchronous wheel 10 to rotate. Then, under the driving action of the synchronous belt 11, the driven synchronous wheel 9 will drive the rotating rod 8 and the dividing disc 5 to rotate. The pins of the diodes located in the multiple card slots 6 will sequentially contact the guiding plate 29 and be guided by the guiding plate 29 to the electric control scissors 4. The electric control scissors 4 will cut the pins of the diodes. The cut diodes will then fall into the discharge track 12, and the pins of multiple diodes to be processed can be quickly cut sequentially, changing the original manual mode and improving the processing efficiency and the dimensional consistency after the pin cutting.

[0035] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense.

[0036] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
