PNP transistor and NPN transistor electrode detection and identification device

Abstract

The invention discloses a PNP transistor and NPN transistor electrode detection and identification device which comprises a machine body, a reversing cavity with two openings in the upper right portion is formed in the top wall of the machine body, transmission shafts extending front and back are symmetrically arranged on the left side and the right side of the reversing cavity, and transmission wheels are fixedly arranged on the outer surfaces of the transmission shafts. Due to the fact that thehead gravity of the transistor is greater than that of the electrode part, the direction of the transistor entering the device is adjusted through the two cross rods; then the four rods are inserted between transistor electrodes; the transistor electrodes are combed through the downward moving force of the mechanical arm, and follow-up electrification and accurate position finding are facilitated; after positive electricity is provided for the transistor base electrode, whether the transistor is of a PNP type or an NPN type is judged according to whether the transistor is electrified or not, so that the the purpose of marking the type of thetransistors is achieved by controlling the printing plate with corresponding words to face down to print corresponding words for the transistors; and meanwhile, the purpose of sorting the transistors into different cavities is achieved by controlling an electromagnet or an air cylinder to work through power on or 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...
