Description

Technical Field

[0001] The present invention relates to the technical field of transistors, and in particular to a transistor pin cutting device and a cutting method thereof. Background Art

[0002] A transistor is a semiconductor device that is mainly used to amplify and switch electronic signals. It is one of the core components of modern electronic technology and is widely used in various electronic devices, such as computers, mobile phones, televisions, and stereos. Transistors are the basic building blocks of integrated circuits and are essential for modern computing and communication devices.

[0003] A transistor usually has three pins, namely the emitter, base and collector. The emitter is an electrode of the transistor, which provides current to the external circuit through the flow of electrons or holes. The emitter of the NPN transistor is a negative electrode, and the emitter of the PNP transistor is a positive electrode. The base is the control end of the transistor, which regulates the current between the emitter and the collector by controlling the current between the base and the emitter. The base current is usually very small, but it plays a decisive role in the working state of the transistor. The collector is the output end of the transistor, and the current flows from the collector to the external circuit. The collector current is regulated by the base current and is usually much larger than the base current.

[0004] During the transistor production process, in order to ensure that the transistor is suitable for different devices, the transistor pins are made relatively long. However, some devices require shorter pins, so the transistor pins need to be cut. In the prior art, the pins are mostly cut manually, and deviations will occur during manual cutting. The accuracy is not high, the operation efficiency is low, and after cutting the pins, the cut pins will splash everywhere, which is difficult to collect and there are certain safety hazards.
