More Information
Summary:The invention relates to a device for removing bad light-emitting diodes. The above-mentioned defective light-emitting diode removing device is used for removing the defective light-emitting diode from a plurality of light-emitting diodes arranged on a light-emitting diode substrate. The above-mentioned bad light-emitting diode removing device includes: A main stage for setting the above-mentioned light emitting diode substrate; A laser irradiating unit for irradiating a laser to a defective light emitting diode existing on the light emitting diode substrate; A light emitting diode removing portion, located between the light emitting diode substrate and the laser irradiating portion, for adsorbing and removing a bad light emitting diode heated by the laser; And a connecting tube connected between the laser irradiation portion and the light emitting diode removal portion. It is used for sealing the space between the laser irradiation part and the light emitting diode removal part, and has flexibility.
