Abstract

The invention provides a light-emitting sorting apparatus and a sorting machine. The light-emitting element sorting apparatus comprises an accommodation unit and a classification unit. The accommodation unit comprises a first accommodation mechanism equipped with a plurality of first accommodation members for receiving the light-emitting elements after being detected; a second accommodation mechanism equipped with a plurality of second accommodation members for receiving the light-emitting elements after being detected; an accommodation body capable of opening or closing the first accommodation mechanism and the second accommodation mechanism; and a classification unit classifying the light-emitting elements according to the grades thereof. The detected light-emitting elements are classified into any one of the plurality of first and second accommodation members by the classification unit. According to the invention, the reliability of the performance of the light-emitting elements is improved, wherein the light-emitting elements can be classified according to the grades thereof within a short time.

Description

technical field [0001] The present invention relates to a light-emitting element detection and sorting machine for classifying light-emitting elements according to detection results. Background technique [0002] Luminous element (Luminous element) is an element that uses a semiconductor that converts electricity into light. It refers to LED (Light-emitting Diode: light-emitting diode), semiconductor laser (Semiconductor laser), etc., and is widely used in display elements such as automotive instruments, In various fields such as display lamps of various electronic devices such as light sources for optical communication, digital display devices, card readers for computers, and backlights. Such a light-emitting element is manufactured through various steps including a step of testing the performance of the light-emitting element, a step of classifying the light-emitting element according to a test result, and the like. [0003] While eliminating the light-emitting elements t...
