[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes, the positive electrode, also called the anode, and the negative electrode, also called the cathode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on, and when a reverse voltage is applied, the diode is turned off. The on and off of a diode is equivalent to the on and off of a switch. The diode is one of the earliest semiconductor devices and is widely used.

[0049] Control the telescopic rod 54 to extend through the second motor 51, so that the U-shaped fixing frame 53 approaches the annular protection cylinder 29 until the second gear 56 meshes with the annular external rack 291. Control the first sliding block 26 to rise through the first electric cylinder 25, thereby driving the second sliding block 27 to move along the strip hole 242 in the direction away from each other until the first gear 42 meshes with the annular internal rack 292;

[0050] Control the rotation of the threaded rod 12 through the first motor 14, thereby controlling the movement of the moving assembly 2 along the guide rod 13 to the right until the top end of the annular protection cylinder 29 and the bottom end of the annular plate 36 are all correspondingly clamped;

[0051] Then control the rotation of the second gear 56 through the third motor 55. The second gear 56 drives the annular protection cylinder 29 to rotate, and the annular protection cylinder 29 drives a plurality of first gears 42 to rotate simultaneously;

[0052] The second electric cylinder 33 controls the turret 34 to slowly move downward, thereby adjusting the cutting length of the diode pins. The turret 34 is located at the center of the annular protection cylinder 29. At the same time, a plurality of diodes rotate synchronously in the clamping mechanism 4. Control the rotation of the third gear 343 through the fourth motor 342. The third gear 343 drives a plurality of fourth gears 344 meshing with it to rotate synchronously. The fourth gear 344 drives the moving rack 346 to move, so that the cutting knife 35 gradually moves towards the diode direction to complete the synchronous cutting of the rotating diode pins, and the surface of the diode pins is flat and does not require secondary processing. After cutting, control the third gear 343 to rotate in the reverse direction through the fourth motor 342, thereby driving the cutting knife 35 to reset;

[0053] Continue to control the rotation of the threaded rod 12 through the first motor 14, thereby controlling the movement of the moving assembly 2 along the guide rod 13 to the right until the annular protection cylinder 29 leaves the cutting assembly 3. Control the telescopic rod 54 to contract through the second motor 51, so that the second gear 56 is away from the annular protection cylinder 29. Control the first sliding block 26 to descend through the first electric cylinder 25, so that the first gear 42 is away from the annular internal rack 292. First, take out the annular protection cylinder 29, and take out the processed diodes and place them in the material storage box 7 for storage. The waste generated by cutting is cleaned through the notch 281 on the annular clamping plate 28;

[0054] Control the threaded rod 12 to rotate in the reverse direction through the first motor 14 to reset the moving assembly 2 and start the next round of work.
