[0002] The light-emitting diode emits light based on the principle of the unidirectional conductivity of the PN junction. The PN junction is a structure formed at the junction of a P-type semiconductor and an N-type semiconductor. When a forward voltage is applied to the PN junction, electrons flow from the N-type region to the P-type region, and holes flow from the P-type region to the N-type region and meet at the junction of the PN junction.

[0003] In the process of light-emitting diode production, the length of its pins is relatively large. Therefore, a shearing device is needed to process the pins. Most of the existing shearing devices are manual, and the shearing efficiency is very low. There are certain deficiencies in use. For this reason, we propose a pin shearing device for light-emitting diode production. Content of the Utility Model

[0009] Preferably, the driving mechanism includes a support column. A first connecting seat and a second connecting seat are respectively fixed to the top and bottom of the support column. The support column is fixed to the base through the second connecting seat. A movable plate is slidably connected to the support column. A spring is installed between the movable plate and the second connecting seat. A knife groove is installed at the top of the movable plate. The top of the support column is installed with a support frame through the first connecting seat. A second motor is installed at the top of the support frame. An eccentric wheel is installed on the output shaft of the second motor.
