LED (Light Emitting Diode) device sorting machine

Abstract

The invention provides an LED (Light Emitting Diode) device sorting machine which comprises a feeding mechanism, a lifting device, a rotating disc, a testing mechanism and a sorting device, wherein the rotating disc is connected with a step motor; the feeding mechanism comprises a vibrating feeding disc and two rows of straight vibrating tracks; two feeding channels are arranged on the vibrating feeding disc; one ends of the two straight vibrating tracks are respectively connected with outlets of the feeding channels of the vibrating feeding disc. According to the LED device sorting machine, measurement of brightness, hue and electric parameter characteristics can be alternately carried out on two LED devices at the same time; feeding is carried out through the two feeding channels of the vibrating feeding disc and the two rows of tracks, so that the feeding efficiency can be enhanced. The lifting device is provided with a double-head lifting mouth, so that the two LED devices can be lifted at the same time; the sorting device is provided with two rows of suction devices, so that the damage to the LED devices caused by single-channel suction negative pressure in the prior art can be decreased, the sorting correctness is high, the sorting speed is high, the manual interference is less, the production process is continuous, the automation degrees is high and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of LED manufacturing and screening processes, in particular to an LED testing and sorting machine. Background technique [0002] At present, with the development of LED display technology, LED display applications and LED lighting applications have low energy consumption, strong color reproduction, long life, and unique shapes, etc., have been more and more widely used in various occasions. LED In the production of devices, different LED devices have different parameters such as brightness, color tone, and electrical parameters. They need to go through a screening process to make LED devices with the same parameters in the same collection barrel, thereby separating LED devices with different parameters. In the screening process of the prior art, the problem of low work efficiency often occurs, because one machine station can only detect one LED device, so the LED devices are arranged in a row waiting for the machine t...

AI Technical Summary

Problems solved by technology

In the screening process of the prior art, the problem of low work efficiency often occurs, because one machine station can only detect one LED device, so the LED devices are lined up in a row and wait for the machine to detect and screen, so the work efficiency is low

In addition, the single-channel suction negative pressure in the prior art will cause damage to the LED devices, causing damage to the sorted LED devices and affecting product quality
