[0002] The diode is a common component of the integrated circuit board. It is fixed to the circuit board through the pins using the welding process to achieve connection with the circuit. When processing the diode, in order to better fit, the diode pins need to be cut and bent.

[0003] After searching, the Chinese patent publication number CN216027720U discloses a pin processing device for diode processing, including a fixed seat, a movable groove, a bending groove and a bending plate.

On the other hand, it realizes bending and cutting by lifting and lowering the lifting plate, which simplifies the process steps and increases the efficiency.

[0019] 2. The present invention, by providing a linear sliding assembly, can achieve the change of the position of the movable knife and the fixed knife through the cooperation of the slider and the slide rail, thereby achieving the adjustment of the cutting length.

[0020] 3. The present invention, by providing an internal threaded barrel and a screw rod, the internal threaded barrel can rotate to adjust the height of the fixed knife through the connection with the screw rod, so that the device can be specifically adjusted according to the different height positions of the pins.

[0021] 4. In the present invention, after cutting is completed, the bending limit plate contacts the cut pin and continues to descend, so that the pin can be bent, and by setting the rounded corners and the bevel, it can prevent the right-angle edge from damaging the pin during bending.

[0022] 5. The present invention, by setting a lower top plate and a lower pressure plate, on the one hand, when the holding block two cooperates with the holding block one, the lower top plate and the lower pressure plate also cooperate to clamp and limit the protruding pins of the diode, so as to prevent the pins from being disconnected due to axial tension during subsequent bending and cutting. On the other hand, the cooperation between the lower top plate and the lower pressure plate can also determine the bending point of the pin to ensure the bending accuracy.
