Abstract:
1. A method for automatically sorting LED according to electrostatic resistance, comprising steps of: (a) laying, on a transport carrier, a LED to be tested; (b) transporting the LED for passing the LED through an electrostatic discharging zone, a lightening evaluating zone, and a sorting zone in sequence along a detecting path by the transport carrier; (c) in the electrostatic discharging zone, discharging an electrostatic power with a detecting voltage to the LED on the transport carrier through an electric conducting member by an electrostatic discharging device during an electrostatic discharging period; (d) in the lightening evaluating zone, inputting a lightening power to the LED on the transport carrier via an electrode of the LED electrically connecting with the electric conducting member by a lighting device and transmitting an evaluating signal to a sorting device according to the lighting condition of the LED; and (e) in the sorting zone, sorting the LED for moving the LED from the transport carrier to a collecting zone by the sorting device according to the evaluating signal.
