Method for automatically sorting leds according to electrostatic resistance and system using the same

A system for automatically sorting LED according to electrostatic resistance, comprising:

• a transport carrier, provided with an electric conducting member, for laying a LED and passing the LED through an electrostatic discharging zone, a lightening evaluating zone, and a sorting zone in sequence along a detecting path;
• an electrostatic discharging device provided in the electrostatic discharging zone, the electrostatic discharging device being electrically connected with the electric conducting member for discharging an electrostatic power with a detecting voltage to the LED on the transport carrier through the electric conducting member while the transport carrier is in the electrostatic discharging zone;
• a lighting device and an evaluating device provided in the lightening evaluating zone, the lighting device being electrically connected with the electric conducting member for inputting a lightening power to the LED on the transport carrier through the electric conducting member, and the evaluating device being transmitted an evaluating signal according to the lighting result of the LED while the transport carrier is in the lightening evaluating zone;
• and
• a sorting device provided in the sorting zone, the sorting device connected with the evaluating device to sort the LED for moving the LED from the sorting zone to a collecting zone according to the evaluating signal.
