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

Abstract

The invention discloses a diode pin measuring device with a correction function and a use method. The device comprises a fixed bottom plate, a clamping block, a support used for inserting a diode packaging body, a rotary clamping mechanism installed on the support, a correction mechanism used for correcting pins of the diode packaging body, an elastic electric shock block used for making contact with or breaking contact with the pins so as to control power-on and power-off, and a measuring mechanism used for measuring the lengths of the pins. The correcting mechanism can be used for correctinga pin, the measuring mechanism can reflect the length of the corrected pin, the two functions are ingeniously combined, and the elastic electric shock block is used for triggering the correcting mechanism to operate, so the ingenious and accurate effects are achieved. Through the cooperation of the rotary clamping mechanism, the correcting mechanism and the measuring mechanism, the device is reliable in correction, and is easy and convenient in measurement.
