Intelligent light-emitting diode (LED) automatic sorting system

Abstract

The invention relates to the technical field of light-emitting diode (LED) sorting, in particular to an intelligent LED automatic sorting system which comprises a conveying module, a turning module, asorting module and a controller. Due to the fact that miniature LEDs are small in size and mass, collision between the miniature LEDs is prone to happening, and a miscellaneous distribution state isformed, the miniature LEDs need to be adjusted and restored to the proper positions before being detected, and the detected LEDs need to be rapidly sorted according to the mass of the LEDs so as to bematched with the mass production speed of the LEDs. Therefore, according to the intelligent LED automatic sorting system provided by the invention, the conveying module penetrates through all the processes of the sorting system, the sorting speed of the LEDs meets the transfer speed of the LEDs in production, the posture of the LEDs is adjusted in cooperation with the turning module, the LEDs enter the sorting module in the same posture, and the LEDs are measured by a detection unit in a unified mode and sorted into different storage boxes so as to be collected, so that the large-batch production speed of the LEDs is met, and the operation efficiency of the intelligent LED automatic sorting system is improved.

Description

technical field [0001] The invention relates to the technical field of LED sorting, in particular to an intelligent LED automatic sorting system. Background technique [0002] Light-emitting diode (LED) is a widely used display device, so its production volume is very large. After the LED production is completed, it needs to be sorted and packaged according to its detected photoelectric parameters, and divided into different grades according to its quality for storage. [0003] During the transfer process of mass-produced LEDs, due to their small volume and mass, micro-LEDs are prone to collide with each other and form a mixed distribution state, making it necessary to restore the LEDs to their proper positions before testing them. , and the LEDs that have been tested need to be sorted quickly according to their quality to match the mass production speed of LEDs. [0004] There are also some technical solutions about LED automatic sorting systems in the prior art. For examp...

[0004] There are also some technical solutions about LED automatic sorting systems in the prior art. For example, a Chinese patent with application number 2013103480307 discloses a device and method for online detection and sorting of LED bulb lamp products. —The off-line detection method of the spectroradiometer, specially designed the station turntable, detection tooling, detection mechanism, detection system, sorting mechanism, and the control system to realize the integrated collaborative control of the entire equipment for the engineering application of the automated production line; The turntable drives the detection tooling to rotate through each station, and the detection mechanism grabs the LED bulb lamp from the detection tooling transferred to the detection station and sends it to the detection system for finished product inspection; after that, the sorting mechanism transfers it to the sorting worker The detected LED bulbs are sorted in the position detection tool; this technical solution has the characteristics of high detection speed, high detection accuracy, high degree of automation and intelligence, and high cost performance, and can be seamlessly integrated into LED lamps. The automatic production of the whole process is realized in the automatic production line, and it can also be used as an independent finished product inspection unit; Improvement of LED sorting efficiency
