Problems solved by technology

[0002] Diode is one of the most commonly used electronic components. Its biggest characteristic is unidirectional conduction, that is, current can only flow from one direction of the diode. The function of the diode is a rectifier circuit, a detection circuit, a voltage stabilization circuit, and various modulation circuits. , are mainly composed of diodes, and in order to distinguish the positive and negative poles of the diode lead angle, the lead angle length of the negative pole is often smaller than the lead angle length of the positive pole, so it is often necessary to lead the diode negative pole in the process of diode production. However, due to the bending of the pins of the diode, it is not easy to distinguish which lead angle is long or short, and it is inconvenient to accurately measure the lead angle length of the diode cathode before correction
