[0002] In the production process of TO-220 packaged transistors, the finished TO-220 packaged transistors produced by the TMTT machine are usually shipped directly in tube packaging. Some customers require the pins of the TO-220 packaged transistors to be trimmed. The conventional cutting machines used for cutting are all bulk TO-220 packaged transistor loading devices (circular oscillation plate loading), which will wear the leads and printing of the transistors, resulting in a decrease in the appearance yield of the tube body.

[0003] To this end, the present application designs an automatic feeding device for a TO-220 packaged transistor corner cutting machine. After using a material tube to assist in feeding, the finished TO-220 packaged transistor can be directly taken out of the material tube and the TO-220 packaged transistor can be introduced into the track for cutting the pins, so as to solve the above problems.
