Abstract

The invention relates to a detection and repair system and a detection and repair method for a light emitting diode product. The system comprises a feeding device, a bearing device, a detecting deviceand a repairing device. The feeding device is used for conveying the LED products to the bearing device; the bearing device is used for bearing an LED product; the detection device is used for detecting each LED chip on the bearing device, judging that the LED chip is an abnormal chip when a detection result does not conform to a preset specification, and acquiring and sending position information of each abnormal chip on the LED product; the repairing device is used for obtaining position information and then illuminating and heating a conductive material between the substrate and an abnormal chip according to the position information, so that the abnormal chip is separated from the substrate, and a preset LED chip is used for replacing each abnormal chip separated from the substrate; and the detection device is also used for detecting a preset LED chip on the LED product. The maintenance of abnormal chips on LED products with small-size LED chips is realized.

Description

technical field [0001] The present application relates to the technical field of testing equipment, in particular to a testing and repairing system and a testing and repairing method for LED products, and a computer device. Background technique [0002] Mini LED (Mini Light Emitting Diode, Mini Light Emitting Diode) refers to an LED with a grain size of about 50 microns to 200 microns, which can be used for new display technologies with a distance between adjacent LED grains of 10 mm to 1.0 mm, such as including outdoor Large-size and various medium and large-size displays can also be used to develop a large number of liquid crystal display backlight markets. [0003] Micro LED technology, that is, LED miniaturization and matrix technology, is to thin, miniaturize and array the LED backlight, so that the LED grains are smaller than 50 microns, and the distance between adjacent LED grains is less than 0.01mm. -Emitting Diode (organic light-emitting diode) can also realize in...
