A device for detecting and identifying electrodes of pnp transistors and npn transistors

Abstract

The invention discloses a PNP transistor and an NPN transistor electrode detection and identification device, comprising a body, a top wall of the body is provided with a reversing cavity with two openings on the upper right, and the reversing cavity is symmetrically provided with a transmission extending forward and backward. The outer surface of the transmission shaft is fixedly provided with a transmission wheel. In the present invention, according to the fact that the gravity of the transistor head is greater than that of the electrode part, the adjustment of the direction of the transistor entering the device is realized through two horizontal bars, and then the four bars are inserted between the electrodes of the transistor, and the manipulator is used to lower the direction of the device. The moving force straightens the transistor electrodes, which is convenient for subsequent power-on to locate the position. After positive power is supplied to the transistor base, it is judged whether the transistor is PNP type or NPN type by whether the transistor is powered on, and then controls the printed board with the corresponding words to face down for the transistor to print the corresponding Text to achieve the purpose of marking the type of transistors, and at the same time, the purpose of sorting transistors into different cavities is achieved by controlling the operation of the solenoid or the cylinder by switching on and off.

Description

technical field [0001] The invention relates to the technical field of transistors, in particular to a device for detecting and identifying electrodes of PNP transistors and NPN transistors. Background technique [0002] A transistor is a solid semiconductor device that acts as a variable current switch that can control the output current based on the input voltage, including diodes, triodes, field effect transistors, thyristors, etc.; [0003] The PNP transistor is composed of two P-type semiconductors sandwiching an N-type semiconductor, while the NPN transistor is the opposite, consisting of two N-type semiconductors sandwiching a P-type semiconductor; [0004] Nowadays, energy saving and environmental protection are gradually deepening in various industries, so transistors can also be recycled and reused to achieve the purpose of energy saving and environmental protection. It is necessary to design a device that can identify, sort and mark unmarked PNP and NPN transisto...
